Description

Technical Field

[0001] The utility model relates to the technical field of leather processing, in particular to a leather water squeezing device for leather processing. Background Art

[0002] In leather processing production, leather will enter a water washing tank for pre-solidification by water washing, and finally form a superfine leather with a very strong sense of genuine leather through ironing, stretching, water squeezing, and film laminating. Therefore, the leather to be processed contains a certain amount of water. In order to remove the water in the leather, a water squeezing machine is often needed to squeeze the water out of the leather, and this kind of water squeezing machine is called a leather water squeezing machine.

[0003] However, when the current leather water squeezing machine squeezes water from leather, most of them stack the leather together and then squeeze it through a pressing plate. This method is prone to uneven stress surfaces on the leather or incomplete extrusion, resulting in poor water squeezing effects, and the leather is easily damaged due to mutual extrusion during force pressing and water squeezing.

[0004] Therefore, a leather water squeezing device is proposed. Content of the Utility Model

Detailed implementation

[0025] In order to make the purpose, technical solution and advantages of the present utility model clearer, the following further details the present utility model in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0026] Please refer to Figures 1 - 4 , the present utility model provides a leather water squeezing device for leather processing, including a water squeezing tank 1 for squeezing water inside to avoid water running out. A rewinder 5 is installed outside the water squeezing tank 1 to facilitate pulling the leather to move, making it easier for the leather to move in the water squeezing tank 1 and ensuring uniform force on the leather during movement. A box door 15 is installed outside the water squeezing tank 1 to facilitate opening the water squeezing tank 1 to place the leather on the extrusion ring 6, and a control panel 14 is installed on the side of the box door 15 for easy operation by the staff. A water outlet hole 4 is provided at the bottom of the water squeezing tank 1 to discharge the water after squeezing for recycling. A first observation window 16 is installed inside the box door 15, and a second observation window 17 is installed at the lower end of the water squeezing tank 1. Through the first observation window 16, it is convenient to observe the water squeezing situation inside, and through the second observation window 17, it is convenient to observe the water storage situation inside to avoid excessive water storage.

[0027] On both sides of the water squeezing tank 1, inlets and outlets 2 penetrating the inside are symmetrically provided to facilitate the leather to penetrate and be pulled from both sides. The inlets and outlets 2 are inclined inwards to make it easier for the leather to move downwards, resulting in better force application. Guide wheels 3 are rotatably connected inside both the inlets and outlets 2 to reduce friction during leather pulling and improve safety. A semi-circular extrusion ring 6 is connected to the lower end inside the water squeezing tank 1, and holes penetrating up and down are provided inside the extrusion ring 6 to facilitate the downward dropping of the squeezed water. The inner wall of the extrusion ring 6 is smoothly arranged to facilitate pulling the leather. An installation bracket 8 is provided at the upper end inside the water squeezing tank 1, and an extrusion roller 9 is connected inside the installation bracket 8. The extrusion roller 9 and the extrusion ring 6 cooperate with each other, so that when the leather is inside the extrusion ring 6, the contact area between the extrusion roller 9, the extrusion ring 6 and the leather is increased, enabling more water to be squeezed out during water squeezing and achieving better water squeezing effect. A first electric push rod 10 is installed at the top of the water squeezing tank 1, and the output end of the first electric push rod 10 penetrates the water squeezing tank 1 and is connected to the installation bracket 8. By pushing the installation bracket 8 with the first electric push rod 10, the extrusion roller 9 moves downward to contact the leather together with the extrusion ring 6 to perform the extrusion work on the leather.

[0028] Rotating rollers 7 are arranged at the upper ends on both sides of the extrusion ring 6 and are rotatably connected to the water extrusion tank 1. An electric motor 18 is installed outside the water extrusion tank 1 and is connected to the rotating roller 7. Moreover, the rotating rollers 7 are all provided with electric motors 18. When the electric motor 18 drives the rotating roller 7 to rotate, the rotating roller 7 can drive the leather to move, facilitating the transmission of the leather under force. On both sides of the mounting frame 8, extension frames 11 are symmetrically arranged, and side extrusion rollers 13 are connected inside the extension frames 11. On both sides of the top end of the water extrusion tank 1, second electric push rods 12 are installed, and the output ends of the second electric push rods 12 penetrate through the water extrusion tank 1 and are connected to the extension frames 11, enabling the second electric push rods 12 and the first electric push rods 10 to simultaneously push the extension frames 11, facilitating the simultaneous pressing of the leather under the action of the rotating rollers 7 and the side extrusion rollers 13, so that both sides of the leather are also subjected to extrusion. And the extrusion on both sides is carried out simultaneously with the extrusion by the extrusion roller 9 and the extrusion ring 6, avoiding the situation of uneven force. Moreover, through the second electric push rods 12, it is convenient to increase the force on both sides, making the downward acting force stronger, resulting in a better water extrusion effect. And in the case of pulling the leather in this way, folding water extrusion can be avoided, reducing the damage situation.

[0029] Working principle: When in use, first connect the winding machine 5, the first electric push rod 10, the second electric push rod 12, the control panel 14 and the electric motor 18 to an external power supply. Then, after opening the box door 15, put the leather placed inside the water extrusion tank 1 through the inlet and outlet 2 onto the upper end of the extrusion ring 6 and connect it to the winding machine 5. Subsequently, the first electric push rod 10 and the second electric push rod 12 work simultaneously, causing the mounting frame 8 and the extension frames 11 to move downward simultaneously. After the extrusion roller 9 first contacts the leather with the extrusion ring 6, the side extrusion rollers 13 and the rotating rollers 7 on both sides press the leather on both sides. Then, with the operation of the winding machine 5 and the electric motor 18, the leather is pulled, enabling the leather to be subjected to water extrusion under pressure, so that the leather is subjected to multiple water extrusions, achieving the purpose of a better water extrusion effect, and thus completing the work.
