Description

Technical Field

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

[0002] Leather is quite common in our daily life. It is a denatured and non-perishable animal skin obtained through physical and chemical processing 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 it feels comfortable. When processing leather, a water squeezer is needed to process the leather;

[0003] After searching, it was found that a leather squeezer suitable for leather processing is disclosed with publication number CN212560310U, including a horizontal plate, and a first support plate and a second support plate are fixedly connected on both sides of the top of the horizontal plate. Although the pressure can be adjusted during use, the leather is squeezed through a single squeeze during use. When the moisture content of the leather is high, the squeezing difficulty increases and it is inconvenient to load the leather. Therefore, a leather squeezer for leather processing is proposed. Utility Model Content

[0004] The purpose of the utility model is to provide a leather squeezing machine for leather processing. Before the leather is completely squeezed, it can be gradually squeezed under the cooperation of a first conveyor belt and a second conveyor belt, thereby reducing the difficulty of leather squeezing and improving the squeezing efficiency. At the same time, a baffle can be used to block debris on the surface of the incoming material to prevent the debris from being squeezed along with the leather, thereby improving the safety of use and solving the existing technical problems.

[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0006] A leather squeezer for leather processing, comprising: a frame, arc-shaped second slideways are provided on both sides of the frame, first sliders are slidably connected in the second slideways, a first lower roller is rotatably connected between the two first sliders, a second lower roller used in conjunction with the first lower roller is rotatably connected between the two sides of the frame, a first conveyor belt is transmission-connected between the first lower roller and the second lower roller, and the upper part of the first conveyor belt is inclined;

[0007] A first upper roller is rotatably connected between the two sides of the frame, an arc-shaped first slideway is provided on both sides of the frame, a second slider is slidably connected in the first slideway, a second upper roller is rotatably connected between the two second sliders, a second conveyor belt is transmission-connected between the first upper roller and the second upper roller, the second conveyor belt is horizontally arranged, a tension spring is fixedly connected between the second slider and the frame, the first conveyor belt is tiltedly arranged, and is used in conjunction with the second conveyor belt, so that the leather can be gradually squeezed under the cooperation of the first conveyor belt and the second conveyor belt before being completely squeezed, thereby reducing the difficulty of leather squeezing and improving the squeezing efficiency;

[0008] The first conveyor belt is longer than the second conveyor belt.

[0009] As a further solution of the utility model, a second motor is fixedly connected to one side of the frame, and one end of the second motor output shaft is fixed to the first upper roller; one side of one of the first sliders is fixedly connected to the first motor, and one end of the first motor output shaft is fixed to the first lower roller.

[0010] As a further solution of the utility model, a connecting frame is fixedly connected between the bottoms of the two first sliding blocks, and a hydraulic cylinder is rotatably connected between the bottom of the connecting frame and the bottom of the frame.

[0011] As a further solution of the utility model, the tops of both sides of the frame are rotatably connected with swing frames, the swing frames are rotatably connected with limit rollers, and an inclined baffle is fixedly connected between the two swing frames.

[0012] As a further solution of the utility model, two horizontal plates are fixedly connected to one side of the frame, and the bottoms of the two horizontal plates are threadedly connected with limiting rods that penetrate through them. The tops of the two limiting rods respectively contact the bottoms of the two swing frames, and limiting rollers and baffles are installed at the feed point, so that the baffle can be used to block debris on the surface of the incoming material to prevent the debris from being squeezed along with the leather, thereby improving safety in use.

[0013] As a further solution of the utility model, a top cover is fixedly connected to the top of the frame.

[0014] As a further solution of the utility model, a material guide plate is fixedly connected to one side of the frame.

[0015] In the present application, when in use, the height of the swing frame is adjusted so that the limit roller on the swing frame is close to the leather. When adjusting, the limit rod is rotated, and the limit rod pushes the swing frame to rotate. After adjustment, the leather that needs to be squeezed is placed on the surface of the first conveyor belt, and the first motor and the second motor are started. The first motor drives the first lower roller to rotate, and the first lower roller and the second lower roller cooperate to drive the first transmission belt to rotate. Similarly, the first upper roller and the second upper roller cooperate to drive the second conveyor belt to rotate. Since the first conveyor belt is inclined and its length is greater than the second conveyor belt, the leather first enters under the second upper roller, and the second upper roller cooperates with the first conveyor belt to perform preliminary squeezing on the leather, and then is gradually squeezed. As the leather gradually enters between the first upper roller and the first lower roller, the water therein is completely squeezed out, reducing the difficulty of squeezing the leather and improving the squeezing efficiency. At the same time, when the leather passes through the baffle, the baffle pushes away the debris placed on the surface of the leather to avoid being squeezed along with the leather, thereby improving the safety of use.

[0016] The embodiments of the present invention have the following beneficial effects:

[0017] In the utility model, the first conveyor belt is tilted and used in conjunction with the second conveyor belt, so that the leather can be gradually squeezed under the cooperation of the first conveyor belt and the second conveyor belt before being completely squeezed, thereby reducing the difficulty of leather squeezing and improving the squeezing efficiency;

[0018] In the utility model, by installing the limiting roller and the baffle at the feeding place, the baffle can block the sundries on the surface of the incoming material, so as to prevent the sundries from being squeezed along with the leather, thereby improving the safety of use;

[0019] In the utility model, before the leather is completely squeezed, it can be gradually squeezed under the cooperation of the first conveyor belt and the second conveyor belt, which reduces the difficulty of leather squeezing and improves the squeezing efficiency. At the same time, the baffle can block the sundries on the surface of the incoming material to prevent the sundries from being squeezed along with the leather, thereby improving the safety of use.

[0020] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
