Description

Technical Field

[0001] This utility model relates to the field of leather processing technology, and in particular to a leather uniform water squeezing device. Background Technology

[0002] In leather processing, squeezing is an important step. Its main purpose is to remove excess water from the leather, laying the foundation for subsequent processing steps. The leather is then washed and pre-coagulated in a water washing tank. Finally, it is ironed, stretched, squeezed, and laminated to form microfiber leather with a strong leather feel. Therefore, the leather being processed will contain a certain amount of water. In order to remove the water from the leather, a squeezing machine is often needed to squeeze out the water.

[0003] Existing leather squeezing devices often suffer from low single-pass processing capacity and low squeezing efficiency. The leather is prone to displacement during the squeezing process, resulting in uneven moisture removal and affecting processing quality. Furthermore, it is difficult to ensure the continuity of squeezing and winding during the winding process, and the winding components are inconvenient to disassemble and assemble, and material handling is time-consuming. In order to address these technical problems, this application proposes a leather uniform squeezing device. Utility Model Content

The contact surface with the snap-fit ​​groove 11 is roughened to enhance the anti-slip effect after fixing.

[0018] Reference Figures 6-10 Several take-up frames 6 are fixedly connected to the left end of the support frame 3. A control box 7 is fixedly connected to the outer wall of the foremost take-up frame 6. A motor 17 is fixedly connected to the inner wall of the control box 7.

[0019] Working principle: When using this squeezing device, multiple sets of leather that need to be squeezed can be passed sequentially through the inlet and outlet on both sides of the water collection tank 1, around the guide wheel and tension roller 9, and placed on the squeezing plate 13. Then, they pass out from the tension roller 9 and the inlet and outlet on the other side and are wound around the outer wall of the take-up roller 15 on the take-up frame 6. Then, the hydraulic push rod 5 is activated by the controller to push the squeezing roller 2 downward to squeeze multiple sets of leather simultaneously. This makes the leather subject to the combined squeezing action from the squeezing roller 2 and the squeezing plate 13 below, so that the water is squeezed out evenly and flows out from the holes on the squeezing plate 13. The water enters the inner wall of the water collection tank 1 and can be discharged through the front outlet pipe. During the squeezing operation, the threaded sleeve 10 can be rotated to make the snap-fit ​​block 12 and the snap-fit ​​groove 11 on the outer wall of the water collection tank 1 come into close contact, thereby preventing the leather from shifting during the squeezing process and affecting the squeezing effect. Then, each section of leather that is squeezed can be driven by the motor 17 to rotate the drive gear 18, which in turn drives the driven gear 19 that meshes with it to rotate, thereby causing the winding shaft 8 to rotate and drive each winding wheel 15 that is snapped with it to rotate, so as to realize the water squeezing and winding operation of the leather section by section. Meanwhile, after the water is squeezed and the roll is finished, the slide plate 20 can be slid on the inner wall of the take-up shaft 8 by rotating the threaded rod 16, so that the insert 21 can be pulled out from the inner wall of the slot 23 on the inner wall of each take-up wheel 15 and the driven gear 19, and then the entire take-up shaft 8 can be gradually pulled out, and then the rolled-up leather can be removed one by one.
