[0014] 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.

[0015] This embodiment discloses an automatic roller wiping mechanism, which aims to solve the problems of time-consuming and labor-intensive manual wiping of coating machine rollers, safety hazards, and reduced production efficiency in the prior art, so as to realize automated and efficient wiping of rollers and ensure coating quality and stable equipment operation.

[0016] Specifically, as shown in the attached document Figure 1 Appendix Figure 2 As shown, the automatic roller wiping mechanism includes a support frame 1, on which a complete wiping assembly is integrated, enabling the positioning, wiping, and residue collection of the roller 4 in one integrated operation.

[0017] As attached Figure 1 Appendix Figure 5 As shown, a slag receiving hopper 2 is provided in the middle of the support frame 1. The slag receiving hopper 2 is located directly below the roller 4 and is slidably connected to the support frame 1, and its position can be adjusted up and down.

[0018] As attached Figure 1 Appendix Figure 4 As shown, positioning discs 3 are respectively provided at both ends of the slag receiving hopper 2. The positioning discs 3 are used for the precise installation and positioning of the roller 4. A limit block 5 is provided on one side of the positioning disc 3. The limit block 5 is fixed to the support frame 1 by bolts to further strengthen the stability of the roller 4 after installation and prevent displacement during the wiping process.

[0019] As attached Figure 1 Appendix Figure 3 As shown, a connecting frame 7 is provided on one side of the slag receiving hopper 2. A guide rod 6 is slidably connected to the middle of the connecting frame 7. The guide rod 6 is fixedly installed on the support frame 1 to provide stable guidance for the movement of the connecting frame 7. A cylinder 8 is hinged to one side of the bottom of the connecting frame 7. A scraper 9 is provided at the output end of the cylinder 8. The scraper 9 is hinged to the connecting frame 7. The extension and retraction of the cylinder 8 can drive the scraper 9 to adhere to or move away from the surface of the roller 4, thereby switching the wiping action.

[0020] As attached Figure 1 Appendix Figure 3 As shown, the bottom of the connecting frame 7 is threaded with a lead screw 10, which is horizontally placed in the middle of the support frame 1. A motor 11 is provided on the outside of the support frame 1 to drive the lead screw 10 to rotate. When the motor 11 is working, it drives the lead screw 10 to rotate, thereby driving the connecting frame 7 to move laterally along the guide rod 6, so as to realize the scraper 9 to wipe the surface of the roller 4.

[0021] As attached Figure 1 Appendix Figure 5As shown, a handle 12 is provided at the bottom of the guide rod 6. The handle 12 is horizontally placed on the support frame 1 and rotatably connected to the support frame 1. Gears 13 are provided at both ends of the handle 12. A limiting frame 14 is provided on the outer side of the gear 13. The limiting frame 14 is installed on the support frame 1 by bolts. A toothed rod 15 is slidably connected to the limiting frame 14. The toothed rod 15 meshes with the gear 13. The top end of the toothed rod 15 extends to the bottom of the slag receiving hopper 2.

[0022] The specific working principle is as follows: First, the roller 4 to be wiped is installed on the support frame 1 through the positioning plate 3, and the position of the roller 4 is fixed by the limit block 5 to ensure its stable operation.

[0023] Start the motor 11, which drives the lead screw 10 to rotate, causing the connecting frame 7 to move laterally along the guide rod 6 to the corresponding position of the roller 4; control the cylinder 8 to extend and retract, pushing the scraper 9 to adhere to the surface of the roller 4. During the rotation of the roller 4, the scraper 9 moves laterally to wipe the glue and residue off the surface of the roller 4.

[0024] The residue generated during wiping falls into the slag hopper 2 below and is collected. When it is necessary to clean the slag hopper 2, turn the handle 12 to drive the gear 13 to rotate. Through the meshing transmission between the gear 13 and the rack 15, the rack 15 pushes the slag hopper 2 upward and adjusts the position of the slag hopper 2 on the support frame 1.

[0025] After wiping is completed, the control cylinder 8 retracts, driving the scraper 9 away from the roller 4, and the motor 11 reverses to drive the connecting frame 7 to reset, waiting for the next wiping operation.

[0026] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
