Description

Technical Field

[0001] This utility model relates to the technical field of leather roller coating machines, specifically to a fast self-correcting and self-peeling conveyor belt component for a leather roller coating machine. Background Technology

[0002] A leather roller coating machine is a specialized piece of equipment used for leather surface treatment. Its main function is to evenly apply coatings, paints, and adhesives to the leather surface to achieve processes such as color change, polishing, film application, and embossing. Existing leather roller coating machines mainly have two roller coating solutions: rubber rollers and traditional conveyor belts.

[0003] When using the rubber roller solution, a coating roller is used in conjunction with a rubber roller to coat the leather. At the exit, the leather is peeled off manually or with a peeling roller, and then conveyed by the rubber roller. However, after being coated by the coating roller, the leather is subjected to the squeezing force of the coating roller and the adhesive force of the rubber roller surface. As a result, the coated leather will stick tightly to the rubber roller. At the leather exit, manual or peeling roller mechanisms are required to peel off the leather, which is a waste of labor. Moreover, during peeling, the undried coating is easy to transfer to the back of the leather, causing product defects. After a period of peeling, the position of the peeling roller is prone to change, causing peeling failure, causing leather jamming, and resulting in serious product defects. Furthermore, when the rubber roller solution is used for "repair" processes, the lack of ideal wrapping corners results in poor repair effects.

[0004] Traditional conveyor belt systems use coating rollers in conjunction with rubber conveyor belts for leather coating. The driving and driven rollers have similar diameters, with an adjustable support roller in the middle. At the exit, manual labor or a peeling roller is used to peel off the leather. While the wrap angle of the traditional conveyor belt system is beneficial for "repair" processes, it lacks an effective correction structure, often resulting in conveyor belt deviation, damage, and equipment downtime. Furthermore, leather adhesion is also a problem in traditional conveyor belt systems, still requiring manual labor or a peeling roller mechanism to peel the leather, which can cause product defects. After a period of peeling, the position of the peeling roller is prone to shifting, leading to peeling failure, leather jamming, and serious product defects. Additionally, the surface of the conveyor rollers becomes uneven due to the entry of chemical dyes, indirectly causing unevenness in the conveyor belt and resulting in surface blemishes during coating. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a fast self-correcting and self-peeling conveyor belt component for a leather roller coating machine, which solves the problems of inconvenient automatic correction and automatic leather peeling in leather roller coating machines.

[0007] (II) Technical Solution

[0008] To achieve the purpose of automatic correction and automatic peeling of leather in the above-mentioned leather roller coating machine, this utility model provides the following technical solution: a fast self-correcting and self-peeling conveyor belt component for a leather roller coating machine, including a frame, a coating roller rotating on the upper part of the frame, a mounting bracket for installing coating equipment fixed on the side of the frame and outside the coating roller, a main drive roller rotating on the lower part of the frame, a tension roller rotating on the lower right part of the frame, a rubber conveyor belt driving between the main drive roller and the tension roller, and a conveying component being provided inside the rubber conveyor belt;

[0009] The conveying component includes a retainer fixed to a frame, a correction cylinder fixed on the retainer, a correction roller mounted on the correction cylinder, a central rotary bearing rotating in the middle of the correction roller, a support frame fixed to the side of the retainer, correction sensors fixed at both ends of the support frame, a cleaning scraper fixed on the retainer, and a water spray nozzle fixed on the cleaning scraper.

[0010] Preferably, the center diameter of the tensioning roller is larger than the diameters at both ends.

[0011] Preferably, the correction roller is composed of several small rollers that can rotate flexibly arranged in a straight line, and the center height is higher than the height on both sides.

[0012] Preferably, a motor is installed inside the frame, and the main drive roller is fixedly connected to the output end of the motor.

[0013] Preferably, the spray nozzle is connected to an external water pump via a water pipe.

[0014] Preferably, the correction sensors are located at both ends of the rubber conveyor belt.

[0015] Preferably, the frame is equipped with an electrical control system, which is connected to the correction cylinder, the motor, the water pump and the correction sensor inside the frame.

[0016] Compared with the prior art, this utility model provides a fast self-correcting and self-peeling conveyor belt component for a leather roller coating machine, which has the following beneficial effects:

[0017] 1. The leather roller coating machine features a fast self-correcting and self-peeling conveyor belt component. The diameter of the drive roller is larger than that of the tension roller. Utilizing the diameter difference, when the leather is conveyed to the exit, due to the larger curvature of the smaller diameter tension roller, the regular leather will automatically detach from the rubber conveyor belt, requiring almost no external force to peel the leather adhering to the conveyor belt.

[0018] 2. The leather roller coating machine features a fast self-correcting and self-peeling conveyor belt component. By using a conveyor belt design, it incorporates a correction roller. The correction roller structure uses the midpoint of the structure as the rotation center, allowing for a large correction angle. It also features a medium-high structure, resulting in a significant correction effect and more efficient change of the conveyor belt's offset direction. Compared to traditional conveyor belts that lack an effective correction structure, this patented correction structure is faster and more effective.

[0019] 3. The leather roller coating machine features a fast self-correcting and self-peeling conveyor belt component. This patent uses a conveyor belt solution. While the correction roller plays a correcting role, its position and height, compared with the existing rubber roller solution, form a more ideal conveyor belt wrap angle, which can make the "damage repair" process more effective than the rubber roller solution.

[0020] 4. The leather roller coating machine features a fast self-correcting and self-peeling leather conveyor belt component. This patented design includes a cleaning scraper and a water spray nozzle structure. Compared with existing conveyor belt solutions, it can effectively clean the main drive roller of chemical dyes that may be attached, thus preventing coating defects caused by dirt.

For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0028] Please see Figure 1-5 This utility model provides a fast self-correcting and self-peeling leather conveyor belt component for a leather roller coating machine, including a frame 1, a coating roller 2 rotating on the upper part of the frame 1, a mounting frame 3 for installing coating equipment fixed on the side of the frame 1 and outside the coating roller 2, a main drive roller 4 rotating on the lower part of the frame 1, a tension roller 5 rotating on the lower right part of the frame 1, a rubber conveyor belt 6 driving between the main drive roller 4 and the tension roller 5, and a conveying component 7 being provided inside the rubber conveyor belt 6;

[0029] The conveying component 7 includes a retainer 8, which is fixed to the frame 1. A correction cylinder 9 is fixed on the retainer 8, and a correction roller 10 is installed on the correction cylinder 9. A central rotary bearing 11 rotates in the middle of the correction roller 10. A support frame 12 is fixed on the side of the retainer 8, and correction sensors 13 are fixed at both ends of the support frame 12. A cleaning scraper 14 is fixed on the retainer 8, and a water spray nozzle 15 is fixed on the cleaning scraper 14. By connecting the main drive roller 4 to a motor installed inside the frame 1, the main drive roller 4 can be driven to rotate. The main drive roller 4 drives the tension roller 5 and the correction roller 10 to rotate through the rubber conveyor belt 6. By utilizing the diameter difference between the main drive roller 4 and the tension roller 5, when the leather is conveyed to the outlet, the leather adhering to the conveyor belt can be peeled off the conveyor belt without the need for external force.

[0030] Furthermore, the center diameter of the tension roller 5 is larger than the diameters at both ends. When a suitable force is applied for tensioning, its outlet end remains almost straight after being bent by the tension force, which can effectively reduce the problem of conveyor belt deviation.

[0031] Furthermore, the correction roller 10 is composed of several small rollers that can rotate flexibly arranged in a straight line, and the center height is higher than the height on both sides, so that the correction roller 10 can be driven by the correction cylinder 9, which drives the entire correction roller 10 to move around the central rotating bearing 11.

[0032] Furthermore, a motor is installed inside the frame 1, and the main drive roller 4 is fixedly connected to the output end of the motor, so that the motor can drive the main drive roller 4 to rotate and work.

[0033] Furthermore, the water nozzle 15 is connected to an external water pump via a water pipe. The electrical control system controls the opening and closing of the water pump by controlling the solenoid valve, thereby realizing the timed control of the water nozzle 15 to spray water mist at time intervals.

[0034] Furthermore, the correction sensor 13 is located at both ends of the rubber conveyor belt 6. The correction sensor 13 is used to detect the position of the rubber conveyor belt 6. If the deviation from the ideal position is too large, the deviation direction is detected and the correction cylinder 9 is informed of the movement direction, so that the correction roller 10 rotates in a certain direction, causing the rubber conveyor belt 6 to deflect during the movement and move in the opposite direction of the original deviation. The correction roller 10 is composed of several small rollers that can rotate flexibly arranged in a straight line, with the center height higher than the height on both sides. They are arranged in sequence and connected to the correction cylinder 9 at both ends. The correction roller 10 can be driven by the correction cylinder 9 to drive the entire correction roller 10 to move around the central rotating bearing 11.

[0035] Furthermore, the frame 1 is equipped with an electrical control system, which is connected to the correction cylinder 9, the motor, water pump, and correction sensor 13 inside the frame 1. This allows the electrical control system to control the correction cylinder 9, the motor, water pump, and correction sensor 13 to work together, either individually or simultaneously. In this application, the electrical control system controls the entry and exit of compressed air into the cylinder via a solenoid valve, causing the cylinder to extend or retract. The force is adjusted by a pressure regulating valve in the pipeline and can be set according to the scraping force. During the extension stroke, there is a blocking block and a blocking shaft welded to it to limit the extension position of the cylinder. The blocking block and the blocking shaft are welded together and can be adjusted forward and backward via a handwheel and a lead screw. The blocking shaft can block the swing arm, indirectly limiting the extension stroke of the cylinder.

[0036] The working principle of this utility model is as follows: During use, by connecting the main drive roller 4 to a motor located inside the frame 1, the main drive roller 4 can be driven to rotate. Therefore, when the roller coating machine is working, the rubber conveyor belt 6 is tensioned by the tension roller 5, effectively connecting the main drive roller 4 and the tension roller 5, and pressing the correction roller 10. The motor drives the main drive roller 4 to drive the rubber conveyor belt 6, and drives the correction roller 10 and the tension roller 5 to rotate. Figure 2 and Figure 5As shown, the correction roller 10 is composed of several small, flexibly rotatable rollers arranged in a straight line, with the center height higher than the sides. These rollers are arranged sequentially and connected to correction cylinders 9 at both ends. The correction roller 10 is driven by the correction cylinders 9, causing it to move around the central rotating bearing 11. During the movement of the rubber conveyor belt 6, belt deviation inevitably occurs. When the correction sensors 13 on both sides receive signals, the electronic control system causes the correction cylinders 9 to move up and down, driving the correction roller 10 to rotate around the central rotating bearing 11. Based on the deviation direction, the correction roller 10 rotates in the opposite direction. At this time, the rubber conveyor belt 6 moves in the opposite direction under the action of the correction roller 10. This process repeats, thus achieving the correction action. The cleaning scraper 14 has water nozzles 15 at both ends along its length. The water nozzles 15 are connected to water pipes outside... The water pump is connected to the electrical control system, which controls the opening and closing of the solenoid valve to start and stop the water pump. This allows the spray nozzle 15 to spray water mist at time intervals, so that the water mist is sprayed on the surface of the main drive roller 4. In conjunction with the cleaning scraper 14, the chemical dye dirt on the roller surface is cleaned during operation. The center diameter of the tension roller 5 is larger than the diameters at both ends to compensate for the bending effect after tensioning. Its size has been calculated so that when a suitable force is applied for tensioning, its outlet end remains almost straight after bending due to the tension force, which can effectively reduce the problem of conveyor belt deviation. The diameter of the main drive roller 4 is larger than that of the tension roller 5. Utilizing the diameter difference, when the leather is conveyed to the outlet, due to the larger curvature of the smaller diameter of the tension roller 5, the regular leather will automatically detach from the rubber conveyor belt 6. No external force is needed to peel the leather adhering to the conveyor belt, thus achieving the purpose of automatic leather peeling.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
