Description

Technical Field

[0001] This utility model relates to the field of leather product processing technology, specifically to a surface treatment device for leather production. Background Technology

[0002] In the production of leather products, in order to improve the appearance, texture and performance of leather, it is often necessary to treat the leather surface. Traditionally, leather surface treatment is carried out by applying coatings with specific effects manually or mechanically.

[0003] According to a public notice (CN219597163U) regarding a leather surface treatment device for leather product manufacturing, the leather is advanced to the surface and comes into contact with the brush on the brush shaft. Then, the dust on the leather surface is swept away, and the suction device is activated to draw the dust generated when the brush shaft sweeps the impurities on the leather into the collection box inside the suction device. This solves the problem that the leather surface treatment device is inconvenient to clean during use, and that impurities on the surface of the leather are often difficult to clean after processing.

[0004] However, in actual use, after the coating is sprayed onto the leather surface, a scraper or other leveling equipment is needed to ensure that the coating thickness on the leather surface is uniform. However, such a leveling structure will continuously accumulate material during continuous operation and will continuously affect the formation effect of the subsequent leather surface coating. Therefore, we propose a surface treatment device for leather production. Utility Model Content

[0005] The purpose of this invention is to provide a surface treatment apparatus for leather production to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a surface treatment device for leather production, comprising a workbench, with I-beams symmetrically fixedly installed at the top of the workbench, a top frame fixedly installed on the top of the two I-beams, and symmetrical transmission rollers rotatably connected between the two I-beams, with a transmission belt sleeved on the outer wall of the two transmission rollers, and a driving component provided between one of the transmission rollers and the I-beam located in front, a conveying pump fixedly installed at the lower edge of the front end of the workbench, the output end of the conveying pump being connected to a hose, a spraying frame fixedly installed between the front and rear ends of the inner side of the top frame, the hose being connected through the spraying frame, and two hydraulic cylinders symmetrically fixedly installed at the top of the top frame, with a scraper fixedly connected to the telescopic shaft ends of the two hydraulic cylinders, the scraper having a drainage mechanism inside for scraping off excess coating from the leather surface and separating and discharging it.

[0007] Preferably, the driving component includes a servo motor, which is fixedly mounted on the front end of the I-beam located near the edge, and the output shaft of the servo motor movably passes through the inner wall of the I-beam located at the front, and the output shaft end of the servo motor is fixedly connected to the front end of one of the transmission rollers.

[0008] Preferably, the drainage mechanism includes a feed trough, an arc-shaped trough, two drainage ports, and two discharge troughs. The feed trough is located on the side wall of the scraper near the lower edge. The arc-shaped trough is located on the inner wall of the scraper near the lower edge, and the arc-shaped trough is connected to the feed trough. The bottom of the arc-shaped trough is lower than the bottom of the feed trough, and an arc-shaped band is fixedly installed on the inner surface of the arc-shaped trough. The two drainage ports are symmetrically located at the bottom of the top frame, and the two discharge troughs are fixedly installed on the inner top of two I-beams.

[0009] Preferably, the scraper is arranged at an angle with its top end close to the spray frame and its bottom end away from the spray frame.

[0010] Preferably, multiple auxiliary rollers are linearly arrayed and rotatably mounted between the two I-beams, and the outer walls of the multiple auxiliary rollers are all in contact with the inner surface of the transmission belt.

[0011] Preferably, the arc-shaped groove is an inverted V-shape with one side higher than the center of the scraper and both ends lower, and the arc-shaped groove is connected to the two drain ports.

[0012] Preferably, the scraper is configured in an arc shape, and the two ends of the arc-shaped scraper are in contact with the inner surfaces of both sides of the top frame.

[0013] Preferably, a triangular baffle is fixedly installed on the outer surface of the scraper near the spray frame. The edge of the triangular baffle away from the scraper is rounded, and the top of the triangular baffle is flush with the lower surface of the feed trough.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: through the cooperation of the scraper, feed trough, arc-shaped trough, arc-shaped belt, drain port, and discharge trough, the scraper can scrape off the excess coating on the leather surface when it comes into contact with the continuously conveyed leather surface. Then, as the coating accumulates, the coating will enter the arc-shaped trough along the feed trough. Since the arc-shaped trough is low at both ends and high in the center, the coating that enters the arc-shaped trough through the feed trough moves towards both ends of the arc-shaped trough. The coating will eventually enter the discharge trough through the drain port and through hole, so that the workers can collect it, realize the separation of excess coating from the leather, ensure the treatment effect of the coating on the leather surface, and reduce the waste of coating.

[0026] 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.

[0027] Example 1: As Figures 1-5As shown, this utility model provides a technical solution: a surface treatment device for leather production, including a workbench 1, with I-beams 2 symmetrically fixedly installed at the top of the workbench 1, a top frame 7 fixedly installed on the top of the two I-beams 2, and symmetrical transmission rollers 4 rotatably connected between the two I-beams 2, with a transmission belt 5 sleeved on the outer wall of the two transmission rollers 4, and a driving component between one of the transmission rollers 4 and the I-beam 2 located in front, a conveying pump 8 fixedly installed at the lower edge of the front end of the workbench 1, with a hose 9 connected to the output end of the conveying pump 8, a spray frame 10 fixedly installed between the front and rear ends of the inner side of the top frame 7, with the hose 9 connected to the spray frame 10, and two hydraulic cylinders 11 symmetrically fixedly installed at the top of the top of the top frame 7, with a scraper 12 fixedly connected to the telescopic shaft ends of the two hydraulic cylinders 11, and a drainage mechanism provided inside the scraper 12 to scrape off excess coating from the leather surface and separate and discharge it.

[0028] Two sets of I-beams 2 provide shielding and support on both sides of the transmission belt 5. At the same time, several sets of auxiliary rollers 6 are set between the two sets of I-beams 2. Meanwhile, the top end of the hose 9 passes through the top frame 7 and is connected to the spray frame 10. When the conveying pump 8 is working, it extracts the coating for leather surface treatment and conveys it to the spray frame 10 through the hose 9. Finally, it is sprayed onto the leather surface conveyed above the transmission belt 5 to form a coating.

[0029] The driving component includes a servo motor 3, which is fixedly mounted on the front end of the I-beam 2 near the edge. The output shaft of the servo motor 3 extends through the inner wall of the I-beam 2 and is fixedly connected to the front end of one of the transmission rollers 4.

[0030] The servo motor 3 acts as a drive device to control one of the transmission rollers 4 to rotate, which, together with the transmission belt 5, enables the horizontal transport of leather materials.

[0031] The drainage mechanism includes a feed trough 13, an arc-shaped trough 14, two drainage ports 16, and two discharge troughs 17. The feed trough 13 is located on the side wall of the scraper 12 near the lower edge. The arc-shaped trough 14 is located on the inner wall of the scraper 12 near the lower edge, and the arc-shaped trough 14 is connected to the feed trough 13. The bottom of the arc-shaped trough 14 is lower than the bottom of the feed trough 13. An arc-shaped band 15 is fixedly installed on the inner surface of the arc-shaped trough 14. The two drainage ports 16 are symmetrically located at the bottom of the top frame 7. The two discharge troughs 17 are fixedly installed on the inner top of the two I-beams 2.

[0032] Please see Figure 4 , Figure 5 , Figure 6The feed trough 13 is located on the side of the scraper 12 near the spray frame 10. Under the control of the hydraulic cylinder 11, the bottom surface of the scraper 12 is close to the leather surface conveyed above the transmission belt 5 to control the gap thickness between the bottom surface of the scraper 12 and the leather, thereby avoiding excessive coating thickness formed by spraying on the leather surface. The scraper 12 scrapes off the excess coating on the leather surface. As the coating accumulates, the paint will enter the arc groove 14 along the feed trough 13. Furthermore, there are two sets of arc belts 15. Both sets of arc belts 15 are located on the side of the arc groove 14 near the feed trough 13, and the arc belts 15 are arranged in a triangular shape to prevent the paint in the arc groove 14 from flowing back to the feed trough 13, thereby facilitating the discharge of excess paint.

[0033] The scraper 12 is inclined with its top end close to the spray frame 10 and its bottom end away from the spray frame 10.

[0034] Please see Figure 3 , Figure 4 The inclined scraper 12 allows excess paint scraped from the leather surface to accumulate at the bottom edge of the scraper 12 and eventually enter the feed trough 13, thus preventing the paint from continuously affecting the leather surface and reducing the leather surface treatment effect.

[0035] Multiple auxiliary rollers 6 are linearly arrayed and rotated between two I-beams 2, and the outer walls of the multiple auxiliary rollers 6 are all in contact with the inner surface of the transmission belt 5.

[0036] Several sets of auxiliary rollers 6 are arranged in a linear array between two sets of I-beams 2, and the auxiliary rollers 6 can provide support for the transmission belt 5 in the vertical direction, so as to avoid uneven coating due to deformation of the transmission belt 5 during the transportation of leather products.

[0037] The feed trough 13 and the arc-shaped trough 14 are connected, and the bottom of the arc-shaped trough 14 is lower than the bottom of the feed trough 13.

[0038] Please see Figure 4 Excess paint flowing into the arc-shaped groove 14 will not easily flow back from the arc-shaped groove 14 to the feed groove 13 and back to the leather surface, ensuring the stable discharge of excess paint.

[0039] The arc-shaped groove 14 is an inverted V-shape with one side higher than the center of the scraper 12 and both ends lower, and the arc-shaped groove 14 is connected to the drain port 16 opened on the inner wall of the top frame 7.

[0040] Please see Figure 5The arc-shaped groove 14 is low at both ends and high in the center, which allows excess paint entering the arc-shaped groove 14 through the feed groove 13 to move towards both ends of the arc-shaped groove 14 under the action of gravity. At the same time, the drain port 16 is located above the discharge groove 17, and the inner wall of the top of the I-beam 2 is provided with a through hole that matches the drain port 16. The excess paint entering the drain port 16 through the arc-shaped groove 14 will eventually enter the discharge groove 17 through the through hole, so that the staff can collect it, realize the separation of excess paint from leather, ensure the treatment effect of the coating on the leather surface, and reduce paint waste.

[0041] Working principle: The leather is placed on the conveyor belt 5, and the servo motor 3 is started. In conjunction with the rotation of the transmission roller 4, the leather is continuously conveyed to one end. At the same time, the conveyor pump 8 is started to extract the coating for the external leather surface treatment and deliver it through the hose 9 into the spray frame 10. Finally, it is sprayed onto the surface of the leather conveyed above the conveyor belt 5 to form a protective coating. Meanwhile, the coating formed by the spraying on the leather surface will come into contact with the scraper 12 as the leather moves. The gap between the bottom surface of the scraper 12 and the leather surface is controlled by the hydraulic cylinder 11. The scraper 12 scrapes off the excess coating on the leather surface. Then, as the coating accumulates, the coating will enter the arc groove 14 along the feed chute 13. Because the arc groove 14 is low at both ends and high in the center, the coating entering the arc groove 14 through the feed chute 13 moves to both ends of the arc groove 14. The coating will finally enter the discharge chute 17 through the drain port 16 and the through hole, so that the staff can collect it and separate the excess coating from the leather. This ensures the treatment effect of the coating on the leather surface while reducing the waste of coating.

[0042] Example 2: Please refer to Figures 9-10 Based on Embodiment 1, the scraper 12 is configured in an arc shape, and the two ends of the arc-shaped scraper 12 are in contact with the inner surfaces of both sides of the top frame 7.

[0043] In this embodiment, the arc-shaped scraper 12 can guide the excess paint scraped off from the contact area between the scraper 12 and the leather from the center to both sides, causing the paint to move away from the center of the leather. While the paint is dispersed and guided, it enters the arc-shaped groove 14 through the feed trough 13 and is discharged outward, avoiding the accumulation of paint on the leather surface and the contact area between the scraper 12.

[0044] A triangular baffle 18 is fixedly installed on the outer surface of the scraper 12 near the spray frame 10. The edges of the triangular baffle 18 away from the scraper 12 are rounded, and the top of the triangular baffle 18 is flush with the lower surface of the feed trough 13.

[0045] Please see Figure 9 , Figure 10The triangular design of the triangular baffle 18 can better guide excess coating on the leather surface upward, causing it to enter the feed groove 13 along the surface of the triangular baffle 18. The rounded corners at the ends of the triangular baffle 18 can prevent the triangular baffle 18 from abrading the leather surface, thus providing a certain degree of protection.

[0046] Working principle: When the arc-shaped scraper 12 is pressed against the continuously conveyed leather surface, the excess coating on the leather surface will be scraped off by the bottom edge of the scraper 12 and flow to both ends through the arc-shaped surface of the scraper 12. Finally, guided by the triangular baffle 18, it will flow towards the feed trough 13 and the arc-shaped trough 14, and finally fall into the discharge trough 17 through the drain port 16 for collection.
