Technical Field

[0001] This utility model relates to the technical field of leather finishing machines, specifically a leather finishing machine with a self-cleaning scraper. Background Technology

[0002] A leather finishing machine is a specialized device used to apply a protective coating to the surface of leather to improve its appearance and physical properties. It mainly uses a rotating printing roller with engraved patterns to precisely apply the finishing paste to the surface of the leather.

[0003] For example, announcement number CN215843871U (named "A Leather Roller Printing and Finishing Machine") includes a frame, and an infeed conveyor belt device, a leather feeding device, a finishing roller, a scraper device, a liquid collection device, and a liquid storage tank mounted on the frame. The leather feeding device includes a leather feeding roller and a drive roller. The leather feeding roller is located near the leather output side of the infeed conveyor belt device. A conveyor belt is fitted onto the outer surfaces of the leather feeding roller and the drive roller. The drive roller is connected to a reducer shaft fixed to the frame, and the reducer is connected to a motor shaft. The finishing roller is located above the leather feeding roller. The scraper devices are respectively arranged on both sides of the finishing roller. The liquid collection device is located below the leather feeding roller and includes a liquid collection box. A connecting arm is provided on the side of the collection box near the feed conveyor belt device. A mounting base is fixed on the top of the connecting arm, and a scraper is installed on the mounting base. A brush roller is rotatably installed on the side of the collection box away from the connecting arm. A second motor is fixed on the outer wall of the collection box, and the second motor is connected to the shaft of the brush roller. Both the scraper and the brush roller are in close contact with the outer surface of the conveyor belt. A detachable filter screen is installed inside the collection box. A liquid outlet is provided at the bottom of the collection box, and a detachable filter screen is installed on the liquid outlet. A solenoid valve is installed below the filter screen at the liquid outlet. The solenoid valve is connected to a storage tank located outside the frame through a liquid outlet pipe. A liquid level sensor is installed on the inner wall of the collection box.

[0004] The aforementioned leather finishing machine uses a scraper mechanism to apply coating to leather. However, the scraper mechanism cannot be effectively cleaned during use, which leads to stains easily adhering to the scraper surface and affecting the coating effect. To address this, we provide a leather finishing machine with a self-cleaning scraper. Utility Model Content

[0005] The purpose of this invention is to provide a leather finishing machine with a self-cleaning scraper, in order to solve the problem mentioned in the background art that the existing leather finishing machines use a scraper mechanism to scrape and coat the leather, but the scraper mechanism cannot be effectively cleaned during use, resulting in stains easily adhering to the scraper surface and affecting the scraping effect.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a leather coating machine with a self-cleaning scraper, comprising a machine frame, a guide roller rotatably arranged inside the machine frame via a rotating shaft, a coating scraper arranged above the guide roller, a hydraulic cylinder arranged on the top of the machine frame, and the coating scraper being welded to one end of the piston rod of the hydraulic cylinder.

[0007] Also includes:

[0008] A water collection pipe frame is provided on both sides of the coating scraper, and a diversion pipe is connected to the inner wall of the water collection pipe frame. One end of the diversion pipe is connected to a cleaning nozzle.

[0009] A water tank is welded to the front end of the machine frame, and two water pumps are installed at the bottom of the water tank. The inlet of each water pump is connected to the inside of the water tank.

[0010] The water trough is located below the guide roller. The water trough and the machine frame are an integral structure. A water receiving pool is provided below the water trough, and a drain outlet is provided on one inner wall of the water receiving pool.

[0011] Preferably, one end of the drain outlet is connected to a water pump, a water pump is provided on one side of the water pump, the inlet end of the water pump is sealed to the drain end of the water pump, and a water supply conduit is provided on the outlet end of the water pump.

[0012] Preferably, belt conveyors are provided on both sides of the machine frame, and a connecting rod is provided between the belt conveyor and the machine frame. The two ends of the connecting rod are welded to the belt conveyor and the machine frame, respectively.

[0013] Preferably, a guide pipe is connected to the outlet end of the water injection pump, and one end of the guide pipe is connected to the water collection pipe frame.

[0014] Preferably, there are seventeen diversion pipes, with equal spacing between adjacent diversion pipes, and the thirty-four cleaning nozzles are arranged in groups of seventeen, located on both sides of the coating blade.

[0015] Preferably, a filter plate is welded inside the drain channel, and a filter screen is fixed inside the drain outlet by screws.

[0016] Preferably, a drive motor is fixedly mounted on the rear end face of the machine frame by screws, and the output shaft of the drive motor is connected to the guide roller via a coupling.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] This invention provides cleaning water to the distribution pipe through a water collection frame. After being discharged through the distribution pipe, the cleaning water is sprayed through a cleaning nozzle to clean the outer walls of both sides of the coating scraper. After cleaning, the cleaning water flows into the water receiving tank through a drain channel and is pre-filtered by a filter plate. After secondary filtration by a filter screen, the cleaning water is pumped out by the water pump through the water pump pipe and injected into the water storage tank for reuse through the water supply conduit. Two water pumps extract water from the water storage tank and inject it into the water collection frame through a guide pipe, achieving the purpose of self-cleaning of the scraper by circulating water. This overcomes the problem that existing leather coating machines use a scraper mechanism to coat leather, but the scraper mechanism cannot be effectively cleaned during use, resulting in stains easily adhering to the scraper surface and affecting the coating effect.
