Description

Technical Field

[0001] The utility model relates to the technical field of coating devices, in particular to a coating device for PU leather production. Background Art

[0002] PU leather consists of a base fabric and a polyurethane coating applied on the base fabric. The polyurethane coating is applied by a coating device. After coating, a smoothing mechanism is used to smooth the coating to ensure the flatness of the polyurethane coating. During smoothing, the smoothing roller rotates in the opposite direction to the movement direction of the base fabric. When the smoothing roller is working, it will be contaminated with paint. After long-term use, there will be a layer of paint on the surface. If it is not removed in time, it will affect the normal use of the smoothing roller. The existing technology generally uses a scraper for scraping, but the scraper will also be contaminated with paint during the scraping process, affecting the scraping effect. Utility Model Content

DETAILED DESCRIPTION

[0021] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0022] like Figure 1 and Figure 3 As shown, a coating device for PU leather production includes a smoothing mechanism, and the smoothing mechanism includes a fixed plate 1, a smoothing roller 2, an opening and closing roller 3 and a scraper 4.

[0023] The number of the fixing plates 1 is two.

[0024] The smoothing roller 2 is rotatably arranged between the two fixed plates 1, and one end is transmission-connected to the driving motor 5 arranged on the fixed plates 1. Preferably, the end of the smoothing roller 2 extends to the outside of a fixed plate 1 and is transmission-connected to the driving motor 5 through a belt 9.

[0025] The opening and closing roller 3 is horizontally movably arranged on the fixed plate 1 through a translation mechanism, and is arranged above the smoothing roller 2. The position of the opening and closing roller 3 is adjustable to adapt to different usage requirements, thereby improving the applicability of the device.

[0026] Specifically, Figure 1 and Figure 2 As shown, the translation mechanism includes a slide rail 10, a slider 11 and a cylinder 12. The slide rail 10 is horizontally arranged on the inner side of the fixed plate 1. The slider 11 is slidably arranged on the slide rail 10, one side of which is connected to the cylinder 12 and driven to slide by the cylinder 12, and the cylinder 12 is fixed on the fixed plate 1. Both ends of the opening and closing roller 3 are connected to the slider 11, and can move along the slide rail 10 with the slider 11 driven by the cylinder 12.

[0027] like Figure 3 As shown, the scraper 4 is arranged on one side of the trowel roller 2, and its top is rotatably arranged on the fixed plate 1 through a rotating mechanism, and its bottom is arranged as a tip. A waste collection box 6 is arranged below the scraper 4. The scraper 4 can rotate so that the tip of its bottom moves away from or close to the trowel roller 3. When it is close to the trowel roller 3, it can scrape off the paint adhered to the surface of the trowel roller 3, so that the paint falls into the waste collection box 6 below under the action of gravity.

[0028] The rotating mechanism includes a rotating rod 13 and a rotating motor 14. The rotating rod 13 is rotatably arranged on the fixed plate 1, and one end is transmission-connected to the rotating motor 14. The top of the scraper 4 is connected to the rotating rod 13 and can rotate with the rotating rod 13. The rotating motor 14 is arranged on the fixed plate 1.

[0029] A scraper cleaning mechanism is provided on one side of the scraper 4. Figure 4 and Figure 5As shown, the scraper cleaning mechanism includes a mounting plate 7 and a rejection block 8. The mounting plate 7 is fixed and vertically arranged between two fixed plates 1. When the scraper 4 is rotated to abut against the mounting plate 7, it is arranged vertically. The rejection block 8 is slidably arranged at the bottom of the mounting plate 7, and a groove is provided on the top thereof, and one end is arranged as an inclined knife portion. The groove is adapted to the tip of the bottom of the scraper 4, so that the rejection block 8 can slide along the bottom of the scraper 4. Since the groove at the top of the rejection block 8 is adapted to the bottom of the scraper 4, it can slide around the bottom of the scraper 4, and the paint adhering to the scraper 4 is removed under the action of the inclined knife portion of the rejection block 8.

[0030] Specifically, the rejection block 8 slides through a sliding mechanism. The sliding mechanism includes a slide groove 15, a sliding protrusion 16, a screw 17 and a sliding drive motor 18. The slide groove 15 is provided at the bottom of the mounting plate 7. The sliding protrusion 16 is fixedly connected to one side of the rejection block 8 and is slidably arranged in the slide groove 15. The screw 17 is arranged in the slide groove 15 and is threadedly connected to the sliding protrusion 16, and one end is transmission-connected to the sliding drive motor 18. The sliding drive motor 18 drives the screw 17 to rotate, and the screw 17 drives the sliding protrusion 16 and the rejection block 8 to slide, thereby realizing the removal of the paint on the scraper 4.

[0031] When the scraper 4 needs to be cleaned, the rotating motor 14 drives the grabbing sensor 13 to rotate, and drives the scraper 4 to rotate until it abuts against the mounting plate 7. At this time, the scraper 4 is arranged vertically, and then the removal block 8 moves to remove the paint stuck on the scraper 4. After the removal is completed, the scraper 4 rotates back to a position close to the smoothing roller 2.

[0032] The preferred specific embodiments of the utility model are described in detail above. It should be understood that ordinary technicians in this field can make many modifications and changes based on the concept of the utility model without creative work. Therefore, all technical solutions that can be obtained by technicians in this technical field based on the concept of the utility model through logical analysis, reasoning or limited experiments on the basis of the existing technology should be within the scope of protection determined by the claims.
