## Background
FIELD
The subject matter herein generally relates to a cross-cut tester, and in particular to a cross-cut tester for adhesion testing of decorative painted film.
BACKGROUND
A cross-cut tester is mainly used to test an adhesion of decorative painted films. The cross-cut tester can carve crosswise on the surface of the film along vertical and horizontal directions, and the film can form many separate grids. A piece of tape can be covered over the separate grids, and the tape is quickly pulled up. The adhesion of the film can be determined by the number of the grids peeling off the film.

DETAILED DESCRIPTION
It will be appreciated that for simplicity and clarity of illustration, where appropriate, reference numerals have been repeated among the different figures to indicate corresponding or analogous elements. In addition, numerous specific details are set forth in order to provide a thorough understanding of the embodiments described herein. However, it will be understood by those of ordinary skill in the art that the embodiments described herein can be practiced without these specific details. In other instances, methods, procedures, and components have not been described in detail so as not to obscure the related relevant feature being described. Also, the description is not to be considered as limiting the scope of the embodiments described herein. The drawings are not necessarily to scale and the proportions of certain parts have been exaggerated to better illustrate details and features of the present disclosure.
Several definitions that apply throughout this disclosure will now be presented.
The term “outside” refers to a region that is beyond the outermost confines of a physical object. The term “substantially” is defined to be essentially conforming to the particular dimension, shape, or other feature that the term modifies, such that the component need not be exact. For example, “substantially cylindrical” means that the object resembles a cylinder, but can have one or more deviations from a true cylinder. The term “comprising” when utilized, means “including, but not necessarily limited to”; it specifically indicates open-ended inclusion or membership in the so-described combination, group, series and the like.
FIG. 1 illustrates an embodiment of a cross-cut tester 100. The cross-cut tester 100 can include a handle 10, a plurality of gaskets 20, a plurality of blades 30, and a position limiting frame 40. The handle 10 can be substantially hollow and columnar. The gaskets 20 can be received in the handle 10. A portion of the blades 30 can be received in the handle 10. The blades 30 and the gaskets 20 can be alternately positioned one-by-one. The position limiting frame 40 can be positioned at one end of the handle 10, and can prevent the blades 30 from moving. The blades 30 can be fixed in the handle 10 with a first screw 51. The gaskets 20 can be fixed in the handle 10 with a second screw 52. The position limiting frame 40 can be fixed in the handle 10 with a third screw 53. A distance between the blades 30 can be the same, and the cross-cut tester 100 can draw many uniform lines at one time.
FIG. 2 illustrates that one end of the first screw 51 (as shown in FIG. 1) can be locked by a nut 54. Thus, the blades 30 can be detachably mounted in the handle 10. One end of the second screw 52 (as shown in FIG. 1) can be locked by a nut 55. Thus, the gaskets 20 can be detachably mounted on the handle 10.
FIG. 3 illustrates that at least one groove 11 can be defined in one end of the handle 10 which can be sealed. A blunt part of the blades 30 (as shown in FIG. 1) can be positioned in the groove 11, and can be broken by the groove 11. A receiving cavity 12 can be defined in the handle 10. The receiving cavity 12 can be configured to receive the gaskets 20 (as shown in FIG. 1) and the blades 30. The other end of the handle 10 can define an obliquely arranged opening 121. An oblique angle of the opening 121 can be the substantially the same as an angle of a front end of each blade 30. The handle 10 can further include a first sidewall 13 and a second sidewall 14, and the first sidewall 13 and the second sidewall 14 are relatively arranged.
A position of the first sidewall 13 adjacent to the opening 121 can define a screw hole 15, the third screw 53 can be screwed into the handle 10, and can be resisted against the position limiting frame 40. A through hole 16 can be defined in a position of the handle 10 away from the opening 121. The through hole 16 can pass through the first sidewall 13 and the second sidewall 14. The through hole 16 can include a resisting portion 161. The resisting portion 161 can be located in the through hole 16 adjacent to the receiving cavity 12. The resisting portion 161 can be substantially a ring, and can be configured to resist against the first screw 51 (as shown in FIG. 1). A substantially long sliding groove 17 can be defined in a substantially central position of the handle 10. An edge of the sliding groove 17 can include a resisting portion 171. The resisting portion 171 can be located in the sliding groove 17 adjacent to the receiving cavity 12. The resisting portion 171 can be substantially ring shaped, and can be configured to resist against the second screw 52 (as shown in FIG. 1). The second screw 52 can resist against the different positions of the sliding groove 17.
FIG. 4 illustrates that each gasket 20 can be substantially a parallelogram. One end of the gasket 20 can include a bevel 21, and a shape of the bevel 21 can be the same as a shape of the front end of the blade 30. The other end of the gasket 20 can define a fixing hole 22. The first screw 51 (as shown in FIG. 1) can pass through the fixing hole 22 to fix the gasket 20 in the handle 10. A substantially central position of the gasket 20 can define a fixing groove 23. A shape of the fixing groove 23 can be substantially the same as a shape of the sliding groove 17 (as shown in FIG. 3). The second screw 52 (as shown in FIG. 1) can pass through the fixing groove 23, and the blades 30 can be fixed to the different positions of the fixing groove 23.
FIG. 5 illustrates that each blade 30 can be substantially a parallelogram. The blade 30 can include a plurality of creases 31. When the blade 30 is blunt, the blunt part of the blade 30 can be easily broken along the creases 31. One end of the blade 30 can define a fixing hole 32. The second screw 52 (as shown in FIG. 1) can pass into the sliding groove 17 (as shown in FIG. 3), the fixing groove 23 (as shown in FIG. 4) and the fixing hole 32, and can pass through the other sliding groove 17. Thus, each gasket 20 can resist against each blade 30, and the blades 30 can be fixed between the gaskets 20.
FIG. 6 illustrates that the position limiting frame 40 can include a first plate 41, a second plate 42, and a third plate 43. The second plate 42 and the third plate 43 can extend along a vertical direction of the first plate 41. The first plate 41, the second plate 42 and the third plate 43 can combine to form a front opening 44 and a back opening 45. An oblique angle of the front opening 44 can be the substantially the same as an angle of the opening 121 (as shown in FIG. 3). A size of the front opening 44 can be smaller than a size of the back opening 45 to prevent the blades 30 (as shown in FIG. 5) from moving. Thus, lines drawn by the blades 30 can be equal. The position limiting frame 40 can be mounted in the opening 121, and the first plate 41 can be attached to the second sidewall 14 (as shown in FIG. 3). The third screw 53 (as shown in FIG. 1) can pass through the screw hole 15 (as shown in FIG. 3) and resist against the blades 30 and the gaskets 20 (as shown in FIG. 1) to the first plate 41. Thus, the blades 30 can be partly and steady surrounded by the position limiting frame 40. A standard width of each blade 30 can be about 9.0±0.1 mm, and the width of some blades 30 can be about 9.24 mm. Therefore, a width of the front opening 44 can be 9.12 mm or 9.26 mm allowing the blade 30 be held in the position limiting frame 40.
The embodiments shown and described above are only examples. Many details are often found in the art such as the other features of a cross-cut tester 100. Therefore, many such details are neither shown nor described. Even though numerous characteristics and advantages of the present technology have been set forth in the foregoing description, together with details of the structure and function of the present disclosure, the disclosure is illustrative only, and changes may be made in the details, especially in matters of shape, size, and arrangement of the parts within the principles of the present disclosure, up to and including the full extent established by the broad general meaning of the terms used in the claims. It will therefore be appreciated that the embodiments described above may be modified within the scope of the claims.
