The subject matter herein generally relates to a sleeve wrapping device.

BACKGROUND

Before entering a dust-free workshop, sleeves of the personnel need to be sealed to decrease a risk of product contamination. However, it is inconvenient to wrap the sleeves manually.

Therefore, there is room for improvement within the art.

DETAILED DESCRIPTION

FIG.1illustrates an embodiment of a sleeve wrapping device100. The sleeve wrapping device100includes a first fixing base12, a second fixing base14, a first supporting frame22, a second supporting frame24, a first roller32, a second roller34, a discharge box42, a receiving box44, and a sleeve wrapping film70.

The first fixing base12is spaced from the second fixing base14. The first supporting frame22is protruded from a side of the first fixing base12facing the second fixing base14, and the second supporting frame24is protruded from a side of the second fixing base14facing the first fixing base12. The first supporting frame22faces and is spaced from the second supporting frame24. The first roller32is rotatably mounted on the first supporting frame22, and the second roller34is rotatably mounted on the second supporting frame24. The first roller32moves back and forth relative to the first supporting frame22and the second supporting frame24. The second roller34moves back and forth relative to the first supporting frame22and the second supporting frame24. That is, the first roller32moves back and forth between the first supporting frame22and the second supporting frame24, and the second roller34moves back and forth between the first supporting frame22and the second supporting frame24.

The discharge box42is used to contain a portion of the sleeve wrapping film70which is unused. The receiving box44is used to collect the sleeve wrapping film70which is used. In at least one embodiment, the discharge box42is located between the first fixing base12and the second fixing base14. The receiving box44is located between the discharge box42and the second fixing base14.

When the first roller32and the second roller34move, the sleeve wrapping device100is switched between a first state and a second state. The first state is that the first roller32and the second roller34are in contact with each other. The second state is that the first roller32and the second roller34are separated.

In at least one embodiment, the sleeve wrapping film70includes a substrate72and a plurality of adhesive layers74on a side of the substrate72. The plurality of the adhesive layers74is spaced from each other and arranged along a length direction of the substrate72. The substrate72includes a first end and a second end. The first end and the second end are located two opposite side of the substrate72along the length direction. The first end of the substrate72is received in the discharge box42, the second end of the substrate72after sequentially winding the first roller32and the second roller34is received in the receiving box44.

When the sleeve wrapping device100is switched from the second state to the first state, two end portions of one of the plurality of adhesive layers74along the length direction are connected to surround a target object80(for example, an arm). Thus, the sleeve wrapping device100may automatically complete a sleeve wrapping process by the adhesive layer74.

In at least one embodiment, the first fixing base12and the second fixing base14may be rectangular parallelepipeds. The first fixing base12and the second fixing base14may be symmetrically arranged. In another embodiment, each of the first fixing base12and the second fixing base14may have any shape. The first fixing base12supports the first supporting frame22, and the second fixing base14supports the second supporting frame24.

In at least one embodiment, the first fixing base12includes a first surface122. The second fixing base14includes a second surface144. The second surface144faces the first surface122. The first supporting frame22is protruded from the first surface122. The second supporting frame24is protruded from the second surface144.

In at least one embodiment, a first end portion222of the first supporting frame22away from the first fixing base12and a second end portion242of the second supporting frame24away from the second fixing base14are at the same height. In at least one embodiment, the first supporting frame22and the second supporting frame24are both horizontally arranged.

In at least one embodiment, the sleeve wrapping device100includes two first supporting frames22and two second supporting frames24. Two first supporting frames22are mounted on the first fixing base12and spaced from each other. Two second supporting frames24are mounted on the second fixing base14and spaced from each other. A first connecting rod322connects the first ends222of the first supporting frames22and passes through the first roller32. The first roller32rotates around the first connecting rod322. A second connecting rod342connects the second ends242of the second supporting frames24and passes through the second roller34. The second roller34rotates around the second connecting rod342.

In at least one embodiment, referring toFIG.2, the first supporting frame22may be elastically connected to the first fixing base12via a first elastic component50(such as a spring), so that the first supporting frame22is telescopically mounted on the first fixing base12. The first connecting rod322is fixedly connected the first supporting frame22. Thus, the first roller32moves back and forth relative to the first fixing base12. The second supporting frame24may be elastically connected to the second fixing base14via a second elastic component55, so that the second supporting frame24is telescopically mounted on the second fixing base14. The second connecting rod342is fixedly connected the second supporting frame24. Thus, the second roller34moves back and forth relative to the second fixing base14.

In at least one embodiment, referring toFIG.2, the first supporting frame22may include a fixing rod224and a movable rod226. The fixing rod224is fixed on the first fixing base12. The movable rod226is connected to an end portion of the fixing rod224facing away from the first fixing base12via the first elastic component50, so that the movable rod226moves back and forth relative to the first fixing base12. The second supporting frame24may also include a fixing rod224and a movable rod226. The movable rod226is connected to an end portion of the fixing rod224of the second supporting frame24facing away from the second fixing base14via the second elastic component55, so that the movable rod226of the second supporting frame24moves back and forth relative to the second fixing base14.

In another embodiment, the first supporting frame22may be fixedly connected to the first fixing base12, and the first connecting rod322may be connected to the first supporting frame22via a first elastic component50. So that the first connecting rod322is telescopically mounted on the first supporting frame22, and the first roller32moves back and forth relative to the first fixing base12. The second supporting frame24may be fixedly connected to the second fixing base14, and the second connecting rod342may be connected to the second supporting frame24via a second elastic component55. So that the second connecting rod342is telescopically mounted on the second supporting frame24, and the second roller34moves back and forth relative to the second fixing base14.

The plurality of adhesive layers74is disposed on a surface of the substrate72. The substrate72is non-sticky, and each adhesive layer74is sticky. A part of the sleeve wrapping film70received in the discharge box42is wound. A third roller442is received in the receiving box44and is connected to a driving device60(such as a motor). The second end of the substrate72is connected to the third roller442. When the driving device60drives the third roller442to rotate, the sleeve wrapping film70is pulled out of the discharge box42and is wound on the third roller442after winding around the first roller32and the second roller34.

Referring toFIG.3, when in the first state, the first roller32is in contact with the second roller34, one of the plurality of adhesive layers74is located at a first side of the first roller32and the second roller34facing away from the discharge box42and the receiving box44. At this time, a target object80is located at a side of the adhesive layer74facing away from the first roller32and the second roller34.

Referring toFIG.4, the target object80contacts the adhesive layer74and moves downward in the vertical direction, thereby separating the first roller32and the second roller34and converting into the second state. The first roller32moves toward the first fixing base12and the second roller34moves toward the second fixing base14until the target object80moves from the first side of the first roller32and the second roller34to a second side of the first roller32and the second roller34opposite to the first side.

Referring toFIG.5, when the target object80is located at the second of the first roller32and the second roller34, the first roller32and the second roller34move toward to each other, thereby converting into the first state. At this time, the first roller32and the second roller34are in contact with each other, so that the two end portions of the adhesive layer74are attached to each other and surround the target object80under the cooperation of the first roller32and the second roller34.

Referring toFIG.6, after the two end portions of the adhesive layer74are attached, the target object80surrounded by the adhesive layer74moves upward in the vertical direction, thereby separating the first roller32and the second roller34and converting into the second state. The target object80surrounded by the adhesive layer74moves from the second side of the first roller32and the second roller34to the first side of the first roller32and the second roller34.

Referring toFIG.7, after the target object80surrounded by the adhesive layer74is located at the first side of the first roller32and the second roller34again, the sleeve wrapping device100returns to the first state. A used part of the sleeve wrapping film70(i.e. the substrate without the adhesive layer74) is transferred into the receiving box44under a pulling of the third roller442driven by the driving device60, and another adhesive layer74is located at the first side of the first roller32and the second roller34facing away from the discharge box42and the receiving box44for wrapping around a next target object.

The first roller32and the second roller34of the sleeve wrapping device100provided in the present disclose moves back and forth relative to the first fixing base12and the second fixing base14, thereby contacting and separating under an action of the target object80. So that the sleeve wrapping device100is switched between the second state and the first state to complete the sleeve wrapping process.
