Description

Technical Field

[0001] This utility model relates to the field of acrylic sheet processing technology, specifically a protective acrylic sheet coating device. Background Technology

[0002] Acrylic sheets are a chemical material, chemically known as polymethyl methacrylate (PMMA). It belongs to the category of plexiglass and is typically transparent, possessing a crystal-like clarity.

[0003] An acrylic sheet coating device is disclosed in CN214524838U. The device uses a dust-adhesive mechanism to further clean the acrylic sheet after it has been cleaned by the dust-blowing mechanism, in order to remove residual dust. However, when the dust-adhesive roller is used for dust adhesion, a large amount of dust will adhere to its roller wall, which will reduce its utilization rate. Therefore, the dust-adhesive roller needs to be replaced frequently, thereby reducing production efficiency. To address this, we propose a protective acrylic sheet coating device. Utility Model Content

[0004] The purpose of this invention is to provide a protective acrylic sheet coating device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a protective acrylic sheet coating device, comprising a frame, wherein both inner side walls at one end of the frame are provided with sliding grooves, one of which has a through hole at its upper end; a support plate is fixedly connected between the two inner side walls of the frame; a conveying mechanism is provided inside the frame near the upper end of the support plate; a reciprocating screw is rotatably connected to the middle of the bottom end of the support plate, and the reciprocating screw passes through the bottom end of the frame and extends to the lower end; a lifting block is threadedly connected to the wall of the reciprocating screw; and L-shaped lifting rods are fixedly connected to both outer walls of the lifting block. Both lifting rods have connecting blocks fixedly connected to their top ends. A rotating rod is rotatably connected between the two connecting blocks. A connecting box is fixedly connected to one of the connecting blocks near the through hole. One end of the rotating rod extends through into the connecting box. A mounting plate is fixedly connected to the wall of the rotating rod. Several dust-adhesive rollers are arranged between the two mounting plates. A worm gear is fixedly connected to the wall of the rotating rod inside the connecting box. A motor is fixedly connected to one side of the top of the connecting box. A worm is fixedly connected to the output end of the motor, and the worm meshes with the worm gear. A film-coating mechanism is installed on the other side of the top of the frame.

[0006] Preferably, a handle is fixedly connected to the bottom end of the reciprocating lead screw.

[0007] Preferably, the two lifting rods are engaged in the sliding groove.

[0008] Preferably, one of the connecting blocks is engaged within the through hole.

[0009] Preferably, both mounting plates are arranged in a cross shape.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: by rotating the handle to drive the reciprocating screw, and then through the linkage of the set lifting block, lifting rod, slide groove, connecting block and mounting plate, the height of the dust-adhesive roller can be adjusted, thereby cleaning acrylic sheets of different thicknesses. At the same time, through the coordinated use of the set mounting plate, several dust-adhesive rollers, rotating rod, worm gear and motor, different dust-adhesive rollers can be replaced for dust-adhesive work again, thus improving production efficiency.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-5This utility model provides a technical solution: a protective acrylic sheet coating device, including a frame 1. Each of the two inner sidewalls at one end of the frame 1 has a groove 101. One groove 101 has a through hole 102 extending through its upper end. A support plate 11 is fixedly connected between the two inner sidewalls of the frame 1. A conveying mechanism 2 is arranged inside the frame 1 near the upper end of the support plate 11. A reciprocating screw 12 is rotatably connected to the middle of the bottom end of the support plate 11, and the reciprocating screw 12 passes through the bottom end of the frame 1 and extends to the lower end. A lifting block 13 is threadedly connected to the wall of the reciprocating screw 12. Two L-shaped lifting rods 14 are fixedly connected to the two outer walls of the lifting block 13. Each of the 14 top ends is fixedly connected to a connecting block 15. A rotating rod 16 is rotatably connected between two connecting blocks 15. A connecting box 3 is fixedly connected to one of the connecting blocks 15 near the through hole 102. One end of the rotating rod 16 extends through into the interior of the connecting box 3. A mounting plate 17 is fixedly connected to the rod wall of the rotating rod 16. Several dust-adhesive rollers 18 are provided between the two mounting plates 17. A worm gear 19 is fixedly connected to the rod wall of the rotating rod 16 inside the connecting box 3. A motor 31 is fixedly connected to one side of the top end of the connecting box 3. A worm 32 is fixedly connected to the output end of the motor 31, and the worm 32 meshes with the worm gear 19. A film-coating mechanism 4 is installed on the other side of the top end of the frame 1.

[0019] Furthermore, a handle is fixedly connected to the bottom end of the reciprocating screw 12, and rotating the handle will drive the reciprocating screw 12 to rotate.

[0020] Furthermore, the two lifting rods 14 are engaged in the slide groove 101, and the two lifting rods 14 will move up and down along the slide groove 101.

[0021] Furthermore, one of the connecting blocks 15 is engaged in the through hole 102, and the lifting rod 14 slides along the inner wall of the through hole 102 through the connecting block 15.

[0022] Furthermore, both mounting plates 17 are arranged in a cross shape, and the cross-shaped mounting plates 17 can be rotated and adjusted to replace different dust-adhesive rollers 18.

[0023] Specifically, when using this utility model, the acrylic sheet is first placed on the conveying mechanism 2, and then the handle is rotated to drive the reciprocating screw 12 to rotate. The rotation of the reciprocating screw 12 drives the two lifting rods 14 to move downward through the lifting block 13. Then, the dust-adhesive roller 18 is driven to contact the acrylic sheet through the connecting block 15 and the mounting plate 17. Then, the conveying mechanism 2 and the coating mechanism 4 are started. At this time, the acrylic sheet will be dust-adhesive cleaned when it passes through the dust-adhesive roller 18. When the acrylic sheet passes through the coating mechanism 4, its surface will be coated. When the dust-adhesive effect of one of the dust-adhesive rollers 18 becomes poor, the motor 31 is started to drive the worm wheel 19 to rotate through the worm gear 32. The worm wheel 19 will drive the mounting plate 17 through the rotating rod 16. At this time, the mounting plate 17 will drive several dust-adhesive rollers 18 to rotate, so that the unused dust-adhesive rollers 18 can be dust-adhesiveed again, thereby improving production efficiency.
