The cleaning apparatus has the advantage of being able to remove fluff on the surface of a fabric and solves the problem of a reduced production quality of fabrics.
A: A polishing apparatus for mobile phone housing production, comprising a base (1). Partition plates (2) are provided at both sides of an inner cavity of the base (1); both the tops and the bottoms of the partition plates (2) are fixedly connected to the inner wall of the base (1); a first motor (3) is fixedly connected to the bottom of the inner cavity of the base (1); threaded rods (4) are fixedly connected to both sides of an output end of the first motor (3); sides of the two threaded rods (4) facing away from each other are movably connected to the partition plates (2). By providing the base, the partition plates, the first motor, the threaded rods, threaded sleeves, an adjustment plate, adjustment recesses, adjustment wheels, support rods, a placement plate, fixed rods, second air cylinders, clamping plates, dust suction hoods, dust removal boxes, fans, filtering elements, third air cylinders, cleaning brushes, accommodation housings, and blocking plates, the problems of the existing polishing apparatuses for mobile phone housing production that fixing is not stable enough and that the apparatuses have no dust collection function are solved. The polishing apparatus for mobile phone housing production has the advantages of stable fixing and dust collection, and is worthy of promotion.
B: Disclosed is a textile dye stirrer capable of uniform stirring, comprising a workbench (1), wherein the top of the workbench (1) is provided with a sliding groove (3), two sides of an inner chamber of the sliding groove (3) are both provided with a sliding rod (19), the top of the sliding rod (19) is provided with a stirring box (5), the top of the workbench (1) is provided with a connecting rod (18), the top of the connecting rod (18) is provided with a bearing plate (10), the bottom of the bearing plate (10) is provided with a stirring motor (9), an output end of the stirring motor (9) is provided with a rotary shaft (6), the top of the rotary shaft (6) passes into the stirring box (5) and extends into the inner chamber of the stirring box (5), two sides of the rotary shaft (6) are both provided with a stirring blade (7), the top of the left side of the stirring box (5) is provided with a feed port (11), and the bottom of the right side of a stirring box (5) is provided with a discharge port (4).
C: A rapid carding device for a textile fabric, comprising a machine body (1). The inner wall of the machine body (1) is rotatably connected to two rotating rollers (2). Hollow cavities are arranged in the middles of the two rotating rollers (2). Dust suction holes (20) in communication with the hollow cavities are uniformly arranged on outer walls of the rotating rollers (2). Bristles (3) are uniformly arranged on the surfaces of the rotating rollers (2). A negative pressure device for enabling the dust suction holes (20) to generate negative pressure is mounted on the inner wall of the machine body (1). The machine body (1) is further provided with an ironing mechanism for ironing the textile fabric. The inner wall of the machine body (1) is rotatably connected to a press roller (18). The surface of the fabric is cleaned by the bristles (3) to remove thread residues and debris on the surface of the fabric. A sliding plug (21) reciprocates to keep the negative pressure at the dust suction holes (20) so as to clean the thread residues and debris brushed by the bristles (3). Gas heated by a heating wire (13) sprays out of a gas spray hole (16) by means of a second gas guide tube (14) so as to iron the fabric. The device can adapt to the carding of different fabrics by setting to adjust the distance between an arc-shaped plate (19) and the press roller (18).
D: Disclosed is a vacuum pump maintenance device, comprising a base (1), wherein an adjusting base (2) is arranged at the top of the base (1), a frame (3) is fixedly connected to the top of the adjusting base (2), a partition plate (4) is fixedly connected to the bottom of an inner cavity of the base (1), first air cylinders (5) are fixedly connected to two sides of the partition plate (4), moving blocks (6) are fixedly connected, on the sides away from the partition plate (4), to the output ends of the first air cylinders (5), supporting strips (7) are movably connected to the tops of the moving blocks (6), and the ends of the supporting strips (7) away from the moving blocks (6) extend to the top of the base (1) and are movably connected to the adjusting base (2).
