Description

Technical Field

[0001] This utility model relates to the field of coating equipment, specifically an automatic coating device for surface treatment of plastic sheets. Background Technology

[0002] When processing plastic sheets, a film needs to be applied to the surface of the plastic sheets to prevent scratches later. The plastic sheets are directly unwound for film application. Due to the long unwinding line, the unwinding speed is not easy to control, resulting in poor film bonding quality. Furthermore, the machine needs to be stopped and the roll changed when the unwinding of a roll of plastic sheet is finished. When the machine is stopped, it is impossible to limit and fix the film roll.

[0003] According to a patent document with publication number CN214820877U, a double-sided laminated board laminating device includes a worktable with multiple support columns evenly installed at the lower end. Sliding mechanisms are provided on both sides of the worktable, and a U-shaped frame is slidably mounted via two sets of sliding mechanisms. A laminated board is placed in the center of the upper surface of the worktable. An electric telescopic column is fixedly installed in the center of the upper inner side of the U-shaped frame. Limiting mechanisms are provided on the upper inner sides of the U-shaped frame. In this technical solution, after lamination, the laminated board is placed on the worktable, and rollers are used to remove air bubbles from the outer surface of the laminated board and eliminate internal gaps, thereby improving the product's adhesion. However, while this solution achieves air bubble removal, it cannot perform friction cleaning of surface impurities before laminating the plastic board, which is inconvenient during use. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide an automatic coating device for plastic sheet surface treatment, thereby solving the problems mentioned in the background section. This invention features a novel structure. During use, a DC motor drives a friction roller to rotate and rub the top of the plastic sheet. The friction roller is a dry cloth roller. The rotation of the friction roller cleans the surface of the plastic sheet while generating static electricity to facilitate the adsorption of the coating later.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic coating device for plastic sheet surface treatment, comprising a base, a housing fixed on the base, a sliding groove on the side of the housing, a slider movably mounted inside the sliding groove, the slider being mounted inside the sliding groove via a support mechanism, a movable box fixed to one end of the slider, a limit roller rotatably mounted inside the movable box, a fixing block fixed to the side of the housing, a displacement mechanism fixed to the fixing block, a support block fixed to one end of the displacement mechanism, and a support component fixed to the support block.

[0006] Furthermore, the support assembly includes a fixing seat with a fixing groove, and a membrane roll is movably installed inside the fixing groove. The membrane roll is installed inside the fixing groove by a limiting ring seat.

[0007] Furthermore, a positioning post is fixed to one side of the fixed base, a limit block is movably installed on the top of the fixed groove, and one end of the limit block is fixed to the bottom of the movable box.

[0008] Furthermore, a support base is welded to one side of the housing, a drive motor is fixedly installed on the support base, an active roller is installed on the drive motor, a driven roller is rotatably installed inside the housing, and a conveyor belt is movably installed between the driven roller and the active roller.

[0009] Furthermore, a fixed tube is fixed on the bottom inner wall of the box, and a movable column is movably installed inside the fixed tube. The movable column is installed inside the fixed tube through a reset mechanism.

[0010] Furthermore, a fixed frame is fixed on the movable column, a DC motor is fixedly installed on the fixed frame, and a friction roller is rotatably installed between the DC motor and the fixed frame.

[0011] Furthermore, a support roller is rotatably installed inside the housing, the support roller moves in coordination with a limiting roller, and a limiting cylinder is rotatably installed inside the housing.

[0012] Furthermore, a rotating motor is fixedly installed on the side of the box, and a transmission roller is installed on the rotating motor, which cooperates with the limiting cylinder.

[0013] The beneficial effects of this utility model are:

[0014] 1. In use, the DC motor drives the friction roller to rotate and rub the top of the plastic sheet. The friction roller is a dry cloth roller. The rotation of the friction roller cleans the surface of the plastic sheet while generating static electricity to facilitate the adsorption of the subsequent film.

[0015] 2. In this utility model, when the fixed seat moves and loses support for the limiting block, the movable box moves downward by its own weight. After the movable box moves downward, the limiting roller and the supporting roller cooperate to squeeze and limit the film plate, thereby facilitating the replacement and use of the film roll.

[0016] 3. In this utility model, after the displacement mechanism pushes the support seat to move outward, the top of the fixing groove opens, which facilitates the quick disassembly of the membrane roll from the inside of the fixing groove. Later, the top of the fixing groove is limited by a limiting block to avoid the impact caused by the up and down shaking of the membrane roll. Attached Figure Description

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] Please see Figures 1 to 5This utility model provides a technical solution: an automatic coating device for plastic sheet surface treatment, including a base 1, a housing 2 fixed on the base 1, a sliding groove 3 on the side of the housing 2, a slider 12 movably mounted inside the sliding groove 3, the slider 12 being mounted inside the sliding groove 3 via a support mechanism 13, a movable box 4 fixed to one end of the slider 12, a limit roller 14 rotatably mounted inside the movable box 4, a fixing block 9 fixed to the side of the housing 2, and a displacement mechanism 10 fixed to the fixing block 9. One end of the displacement mechanism 10 is fixed with a support block 16, and a support component 5 is fixed on the support block 16. The support component 5 includes a fixed seat 17, and a fixed groove 18 is opened on the fixed seat 17. A membrane roll 19 is movably installed inside the fixed groove 18. The membrane roll 19 is installed inside the fixed groove 18 through a limiting ring seat 20. The displacement mechanism 10 is a linear reciprocating electric push rod. The displacement mechanism 10 drives the fixed seat 17 to move back and forth. When the fixed seat 17 moves back and forth, it achieves secondary support through the positioning column 21.

[0025] In this embodiment, a positioning column 21 is fixed on one side of the fixed base 17, a limiting block 15 is movably installed on the top of the fixed groove 18, one end of the limiting block 15 is fixed to the bottom of the movable box 4, a support base 6 is welded on one side of the box body 2, a drive motor 7 is fixedly installed on the support base 6, an active roller 23 is installed on the drive motor 7, a driven roller 22 is rotatably installed inside the box body 2, a conveyor belt 8 is movably installed between the driven roller 22 and the active roller 23, a fixed tube 28 is fixed on the bottom inner wall of the box body 2, a movable column 27 is movably installed inside the fixed tube 28, the movable column 27 is installed inside the fixed tube 28 through a reset mechanism 29, the reset mechanism 29 is a reset spring, the reset spring pushes the movable column 27 to move downward, the movable column 27 moves downward so that the friction roller 24 contacts the top of the plastic plate of different thicknesses to achieve friction cleaning.

[0026] In this embodiment, a fixed frame 25 is fixed on the movable column 27, and a DC motor 26 is fixedly installed on the fixed frame 25. A friction roller 24 is rotatably installed between the DC motor 26 and the fixed frame 25. A support roller 30 is rotatably installed inside the housing 2. The support roller 30 is movably engaged with the limiting roller 14. A limiting cylinder 31 is rotatably installed inside the housing 2. A rotating motor 11 is fixedly installed on the side of the housing 2. A transmission roller 32 is installed on the rotating motor 11. The transmission roller 32 engages with the limiting cylinder 31. The support mechanism 13 is a support spring. The support spring pushes the movable box 4 to move downward. After the limiting block 15 separates from the fixed seat 17, the movable box 4 can descend quickly.

[0027] Working Principle: In use, one end of the plastic sheet is placed on the conveyor belt 8. The drive motor 7 is started to move the conveyor belt 8 and the plastic sheet. When the plastic sheet moves to the bottom of the friction roller 24, the top of the plastic sheet contacts the friction roller 24. According to the thickness of the plastic sheet, the friction roller 24 is pushed upward. When the friction roller 24 moves upward, the reset mechanism 29 pushes the movable column 27 to apply the opposite force. Under the push of the movable column 27, the friction roller 24 is kept in constant contact with the plastic sheet. The DC motor 26 is started to drive the friction roller 24 to rotate. When the friction roller 24 rotates, it removes impurities from the surface of the plastic sheet. At the same time, the friction roller 24 is made of drying cloth. The friction of the insulating drying cloth generates static electricity on the plastic sheet. After the plastic sheet generates static electricity, it is easier for the film to be adsorbed later. After the plastic sheet passes the bottom of the transmission roller 32, the film at the bottom of the transmission roller 32 is pressed and installed on the plastic sheet. On the board, as the plastic board moves, the transmission roller 32 rotates, driving the film to move. The transmission roller 32 adheres the film to the surface and provides compression, which facilitates the film to fully cover the plastic board. When the film on the film roll 19 is about to run out, the displacement mechanism 10 is activated to push the fixed seat 17 to move outward. After the fixed seat 17 moves outward, one end of the top of the fixed seat 17 separates from the limiting block 15. After the limiting block 15 loses its support, the movable box 4 loses its support force. Under the push of the support mechanism 13, the movable box 4 descends rapidly. After the movable box 4 descends, the limiting roller 14 moves to the top of the support roller 30. The limiting roller 14 and the support roller 30 cooperate to complete the compression and fixation of the film, effectively avoiding the impact caused by the separation between the film and the roller. After the fixed seat 17 moves outward, the top opening of the fixing groove 18 opens, and the film roll 19 is removed upward for replacement.
