Description

Technical Field

[0001] The utility model relates to the technical field of leather cleaning machines, in particular to an automatic leather cleaning machine for a leather production line. Background Art

[0002] Leather is a denatured and non-perishable animal skin obtained through physical and chemical processes such as depilation and tanning. Leather is made of natural protein fibers tightly woven in three-dimensional space. Its surface has a special grain layer with natural grain and luster, and feels comfortable.

[0003] During the leather processing, the grease on the leather surface needs to be removed. However, since the thickness of the grease on each leather is different, when the existing equipment removes the grease on the leather, the distance between the cutter and the grease on the leather is fixed. As a result, when the existing equipment removes the thicker grease on some leathers, the grease on the leather surface cannot be removed all at once, so that grease still remains on the leather surface. When removing some thinner grease, the equipment may easily scratch the leather, thereby affecting the quality of the leather. Utility Model Content

A long groove is provided on the bottom surface of the base, and a movable block is threadedly connected to the surface of the threaded rod. The movable block is slidably connected with the threaded rod and the long groove. Connecting rods are fixedly mounted between the two side surfaces of the movable block and the two U-shaped plates. An adjustment device is provided on the side of the base, and the adjustment device includes an L-shaped bracket, and the L-shaped bracket is fixedly mounted on the side of the base. A moving groove is provided on the surface of the vertical end of the L-shaped bracket, and a displacement plate is slidably connected inside the moving groove. Two support rods are fixedly mounted on the end of the displacement plate away from the moving groove, and a scraper is fixedly mounted on the end of the two support rods away from the displacement plate.

[0011] Compared with the prior art, the advantages and positive effects of the utility model are:

[0012] 1. In the utility model, by setting an adjustment device, when it is necessary to adjust the position of the scraper according to the naive thickness of the leather surface, first loosen the bolt and screw it out from the inside of the threaded hole. The bolt and the threaded hole are separated so that the sliding plate loses its limit in the second vertical groove. At this time, the sliding plate is slid, and the sliding plate moves in the second vertical groove to drive the displacement plate to move in the moving groove. The movement of the moving plate in the moving groove drives the support rod to move, and the movement of the support rod drives the scraper to move. When the scraper moves to a suitable position, the bolt is screwed into the corresponding threaded hole again to fix the position of the sliding plate in the second vertical groove at this time. When the position of the scraper is adjusted, the leather on the surface of the unwinding roller is pulled to place the leather on the surface of the bearing plate, and then the air is started. The cylinder is started and drives the pressing plate to move inside the first vertical groove. The pressing plate moves inside the vertical groove so that it presses the leather and fixes it on the surface of the supporting plate. Then the motor is started and drives the threaded rod to rotate. The threaded rod rotates and drives the movable block to move inside the long groove. The movable block moves inside the long groove and drives the connecting rod to move. The movement of the connecting rod drives the two U-shaped plates to move inside the slide groove. The two U-shaped plates move inside the slide groove and drive the leather to move, so that the grease on the leather contacts the scraper. The scraper scrapes off the grease on the leather to complete the cleaning of the leather. Through the cooperation of the above structure, the position of the scraper can be adjusted, so as to prevent the scraper from scratching the leather when removing some thinner grease, thereby improving the quality of leather processing.

[0013] 2. In the utility model, by setting a limit device, when the leather on the unwinding roller is cleaned and the uncleaned leather needs to be rewound on the surface of the unwinding roller, the pull rod is pulled first, and the movement of the pull rod drives the movable plate to move inside the groove. The movement of the movable plate inside the groove will squeeze the spring, so that the spring is compressed. At the same time, the movement of the movable plate inside the groove also drives the insertion rod to move. The movement of the insertion rod causes it to move out from the inside of the socket. The separation of the insertion rod and the socket causes the mounting plate to lose its limit inside the mounting groove. At this time, the mounting plate is pushed upward and pushed out from the inside of the mounting groove to complete the disassembly operation of the unwinding roller. Then the uncleaned leather is rewound on the surface of the unwinding roller. Through the cooperation of the above structure, the unwinding roller and the mounting seat can be disassembled, thereby facilitating subsequent feeding operations and further improving the practicality of the device.
