AI Technical Summary
Existing leather squeezing devices become more difficult to squeeze when the leather has a high moisture content, and are also inconvenient to feed, resulting in low squeezing efficiency and potential damage to the leather.
A dewatering device for producing metal-free plain-grain calfskin shoe uppers was designed. It adopts a double-layer conveyor belt structure, with the first conveyor belt being higher than the second conveyor belt. The leather first passes through the first conveyor belt for preliminary dewatering, and the remaining water is then completely squeezed out through the second conveyor belt. The pressure is adjusted by regulating the spacing between the conveyor belts and the height of the rollers using a cylinder. The inclined guide pattern is also designed to facilitate water discharge.
It enables staged water squeezing, reduces the difficulty of squeezing when the moisture content is high, improves squeezing efficiency, reduces the risk of damage to the leather, and facilitates leather loading.

Abstract
Description
Technical Field
[0001] This utility model belongs to the field of leather dewatering technology, specifically, it relates to a dewatering device for producing metal-free plain-weave calfskin shoe uppers. Background Technology
[0002] Leather is a common material in daily life. It is animal hide that has undergone physical and chemical processing, such as hair removal and tanning, and is therefore less prone to decay. Leather is composed of natural protein fibers tightly woven in three-dimensional space. Its surface has a special grain layer, which has a natural grain and luster, and a comfortable feel. When processing leather, a dewatering machine is needed to process it. Existing devices often squeeze the leather in one pass, which becomes more difficult when the leather has a high moisture content. It is also inconvenient to feed the leather. Therefore, a leather dewatering machine for leather processing is proposed. Utility Model Content
[0003] To solve the above-mentioned technical problems, this utility model provides a new technical solution:
[0004] A dewatering device for producing metal-free plain-weave calfskin shoe uppers includes a housing and a conveyor. The housing has openings on the left and right sides. The conveyor passes through the openings on both sides and is installed inside the housing. Inside the housing, there is a first conveyor belt and a second conveyor belt. The first conveyor belt is located on the upper left side of the conveyor, and the second conveyor belt is located on the upper right side of the conveyor. The conveyor drives the leather to pass through the first conveyor belt and the second conveyor belt in sequence.
[0005] The height of conveyor belt one is higher than the height of conveyor belt two, and both conveyor belt one and conveyor belt two include a first roller, a second roller, a support, and a cylinder. The first roller and the second roller are both set perpendicular to the forward direction of the conveyor. The rollers at both ends of the first roller are rotatably connected to the inner wall of the housing. The second roller is an electric roller. The support is fixedly connected to the inner top of the housing, or the support is vertically connected to the inner top of the housing through a cylinder. The rollers of the electric roller are fixedly connected to the lower part of the support.
[0006] Furthermore, the fixed end of the cylinder is fixedly connected to the top inner side of the housing, and the moving end of the cylinder is fixedly connected to the top center of the bracket. The cylinder drives the bracket to move closer to or further away from the conveyor. The cylinder can adjust the position of the bracket up and down, thereby adjusting the squeezing interval to meet the squeezing needs of different leathers.
[0007] Furthermore, the second roller includes a roller, a motor, and two roller shafts. The roller shafts are located at the center of both ends of the roller and are rotatably connected to the roller. The motor is coaxially located inside one end of the roller. The output shaft of the motor is fixedly connected to the roller shaft near the motor. The housing of the motor is fixedly connected to the roller.
[0008] Furthermore, the support frame is in the shape of a "door", and the rollers of the electric roller are fixedly connected to the lower two ends of the "door" shaped support frame.
[0009] Furthermore, a base frame is provided at the bottom of the shell to support the bottom of the shell.
[0010] Furthermore, a drainage pipe is provided at the bottom of the shell. The upper end of the drainage pipe is fixedly connected to the shell through a horn-shaped cover. Small holes are evenly distributed on the bottom surface of the shell corresponding to the horn-shaped cover. The lower end of the drainage pipe is connected to the drain pipe to collect the wastewater generated by the extrusion and to centrally treat the wastewater.
[0011] Furthermore, the surface of the conveyor belt of conveyor belt one is provided with guide patterns to guide the moisture generated by the leather during the squeezing process.
[0012] Furthermore, the guide ripples are set at an angle relative to the conveying direction of the conveyor belt, and the angled setting of the guide ripples makes it easier to drain water during the squeezing process.
[0013] This utility model also includes other devices or components that enable the dewatering device for producing metal-free plain-weave calfskin shoe uppers to function normally, all of which are conventional technical means in the art. Furthermore, the housing and motor not specified in this utility model also employ conventional technical means in the art.
[0014] The working principle of this utility model is as follows: when this device is in use, the leather is placed on the conveyor through the opening on the left side of the housing and is driven to move to the right by the conveyor. It passes through conveyor belt one and conveyor belt two in sequence. The height of conveyor belt one is higher than that of conveyor belt two. The leather passes through conveyor belt one first, squeezing out a large amount of water inside the leather. Then it passes through conveyor belt two, where the remaining water in the leather is squeezed out.
[0015] The beneficial effects of this invention are that the device performs the water-squeezing operation on the leather in two stages, avoiding the problem that the squeezing of the roller is difficult and the water-squeezing efficiency is low when the leather has a large amount of moisture. The device can also adjust the height of the second roller in the first and second conveyor belts by means of a cylinder. Lowering the height of the second roller can gradually increase the squeezing force on the leather and reduce the damage that may be caused to the leather by a sudden increase in squeezing pressure.
