Description

Technical Field

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

[0002] A leather dewatering machine is a specialized piece of equipment used in the leather manufacturing process to squeeze out the moisture from leather. It mainly uses rollers or pressure rollers to apply pressure to the leather to squeeze out the moisture, thereby improving the quality and durability of the leather. It is widely used in leather manufacturing, footwear, bags, furniture and other industries.

[0003] When using a leather squeezing machine to squeeze out water from leather, the main method is to use two opposing rotating pressure rollers to mechanically squeeze the leather, which in turn moves the leather and processes the entire piece of leather. However, as the leather gradually enters the two pressure rollers, it may shift. The shifted leather may fold during the processing, which will result in incomplete squeezing and reduce the quality of the leather. Utility Model Content

[0004] This invention provides a leather dewatering device to address the problem that leather may shift as it gradually enters the two rollers, and the shifted leather may fold during processing, resulting in inadequate dewatering and reduced leather quality.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a leather squeezing device, comprising an operating table and a side plate, wherein the side plate is disposed on one side of the operating table, and two squeezing belts are disposed between the side plate and the operating table, wherein pressure rollers are symmetrically disposed inside the squeezing belts, and the two ends of the pressure rollers are respectively rotatably disposed on one side of the operating table and the side plate, wherein the same connecting plate is fixedly installed on the top of the side of the operating table and the side plate that are close to each other, and one side of the connecting plate abuts against the outer surface of one of the squeezing belts, wherein a limiting device is disposed on the outer surface of the other squeezing belt, and the limiting device limits and squeezes the leather by driving the circular hole plate of the roller.

[0006] The effects achieved by the above components are as follows: the perforated plate and rollers can limit the leather, which helps to prevent the leather from shifting during movement, thereby preventing the leather from folding during processing, facilitating the squeezing process of the leather, and ensuring the quality of the leather.

[0007] Preferably, the limiting device includes a threaded rod, with both ends of the threaded rod fixedly installed on one side of the operating table and the side plate, respectively. Two circular hole plates are slidably connected to the outer surface of the threaded rod. Several rollers are provided on one side of the circular hole plates, with one roller rotatably disposed on one side of the circular hole plate. Nuts are provided on both sides of the circular hole plates, and the outer surface of the threaded rod is threadedly connected to the inner walls of the two nuts.

[0008] The effect achieved by the above components is as follows: by setting two perforated plates, the perforated plates are pushed to slide on the outer surface of the threaded rod until the two perforated plates are located on both sides of the leather and are about to come into contact with the leather. At the same time, the roller comes into contact with the top of the leather. The perforated plates and the roller can limit the movement of the leather, and the roller will not obstruct the movement of the leather, which helps to prevent the leather from shifting during the movement.

[0009] Preferably, a limiting plate is fixedly installed on one side of the perforated plate, and one side of the limiting plate abuts against the outer surface of one of the extrusion strips.

[0010] The effect achieved by the above components is that by setting the limiting plate, the circular hole plate can be limited and guided, so that when the circular hole plate is adjusted, the circular hole plate will not deviate excessively, resulting in a large gap between the circular hole plate and the bottom extrusion strip.

[0011] Preferably, a rubber ring is fixedly installed on the outer surface of the roller.

[0012] The effect achieved by the above-mentioned components is that by setting a rubber ring, the outer surface of the roller can be used to contact the outer surface of the leather, thus providing a certain degree of protection for the leather.

[0013] Preferably, one side of the roller is symmetrically provided with a T-shaped groove, and the other side of the roller is symmetrically fixedly installed with a pin. One end of the pin is fixedly installed with a rubber block, and the pin and the rubber block are inserted into the inner wall of the T-shaped groove of the adjacent roller.

[0014] The effect achieved by the above components is as follows: by setting a rubber block, one end of the rubber block is smaller, which makes it easier to insert the rubber block and the pin into the inner wall of the T-slot by taking advantage of the good deformation ability of the rubber block. At the same time, the other end of the rubber block is larger, which can limit the position between the pin and the T-slot, thereby enabling the connection of adjacent rollers and facilitating the disassembly of the rollers. The number of rollers can be increased or decreased according to the actual situation of the leather.

[0015] Preferably, the adjusting assembly includes a slider that is slidably mounted on the inner wall of the circular hole plate. An auxiliary plate is fixedly mounted on one side of the slider, and one of the rollers is rotatably mounted on one side of the auxiliary plate via a bearing. Bolts are symmetrically threaded onto one side of the auxiliary plate.

[0016] The effect achieved by the above components is as follows: by setting a slider, the roller connected to the slider can move on one side of the circular hole plate. At the same time, by rotating the two bolts, one end of the bolts abuts against one side of the auxiliary plate, the roller can be fixed, thus facilitating the adjustment of the roller height according to the thickness of the leather.

[0017] Preferably, the top of the slider and one side of the inner wall of the circular hole plate are fixedly installed with the same spring, the spring is provided with a guide rod, the slider is slidably installed on the outer surface of the guide rod, and the two ends of the guide rod are respectively fixedly installed on both sides of the inner wall of the circular hole plate.

[0018] The effect achieved by the above components is as follows: by setting a spring, the spring will move the slider without the influence of external force, which can drive the roller to move downward until the roller abuts the leather, thus facilitating the quick adjustment of the roller by the spring. At the same time, by setting a guide rod, the spring can be limited to prevent the spring from bending during deformation.

[0019] Preferably, a rubber plate is symmetrically fixedly connected to one side of the perforated plate, and grooves are uniformly provided on one side of the rubber plate.

[0020] The effect achieved by the above components is that by setting a rubber plate with grooves, the friction between the bolt and the round hole plate can be increased, making the bolt more securely fixed to the roller.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this invention, by setting a limiting plate with rollers, the limiting plate and rollers can block and limit the leather, which helps to prevent the leather from shifting during movement, thereby preventing the leather from folding during processing, facilitating the squeezing process of the leather, and ensuring the quality of the leather.

Detailed Implementation

[0024] Example 1, referring to Figures 1-3 As shown, this embodiment discloses a leather squeezing device, including an operating table 1 and a side plate 2. The side plate 2 is disposed on one side of the operating table 1. Two squeezing belts 3 are disposed between the side plate 2 and the operating table 1. Pressure rollers 4 are symmetrically disposed inside the squeezing belts 3. The two ends of the pressure rollers 4 are respectively rotatably disposed on one side of the operating table 1 and the side plate 2. The operating table 1 is equipped with a motor and a reducer, which can drive the upper and lower pressure rollers to rotate, thereby driving the two squeezing belts 3 to mechanically squeeze the leather. The two squeezing belts 3 are of different widths, with the wider one located at the bottom and the narrower one at the top, which facilitates feeding. The same connecting plate 5 is fixedly installed on the top of the side of the operating table 1 and the side plate 2 that are close to each other. One side of the connecting plate 5 abuts against the outer surface of one of the squeezing belts 3. The connecting plate 5 can limit the top squeezing belt 3 to ensure that the top squeezing belt 3 remains extended during rotation. The outer surface of the other squeezing belt 3 is disposed... A limiting device 6 is provided, which includes a threaded rod 61. The two ends of the threaded rod 61 are fixedly installed on one side of the operating table 1 and the side plate 2, respectively. Two circular hole plates 62 are slidably connected to the outer surface of the threaded rod 61. Several rollers 63 are provided on one side of the circular hole plates 62. One of the rollers 63 is rotatably mounted on one side of the circular hole plate 62. Nuts 64 are provided on both sides of the circular hole plates 62. The outer surface of the threaded rod 61 is threadedly connected to the inner wall of the two nuts 64. By setting the two circular hole plates 62, the circular hole plates 62 are pushed to slide on the outer surface of the threaded rod 61 until the two circular hole plates 62 are respectively located on both sides of the leather and are about to abut against the leather. At the same time, the rollers 63 abut against the top of the leather. The circular hole plates 62 and the rollers 63 can limit the movement of the leather. At the same time, the rollers 63 will not obstruct the movement of the leather, which helps to prevent the leather from deviating during the movement.

[0025] Reference Figure 2 and Figure 3 As shown, a limiting plate 65 is fixedly installed on one side of the perforated plate 62. One side of the limiting plate 65 abuts against the outer surface of one of the extrusion belts 3. By setting the limiting plate 65, the perforated plate 62 can be limited and guided, so that when the perforated plate 62 is adjusted, the perforated plate 62 will not deviate excessively, resulting in a large gap between the perforated plate 62 and the bottom extrusion belt 3. A rubber ring 66 is fixedly installed on the outer surface of the roller 63. By setting the rubber ring 66, it can replace the outer surface of the roller 63 to abut against the outer surface of the leather, which can play a certain protective role for the leather.

[0026] Reference Figure 4As shown, T-shaped slots 67 are symmetrically provided on one side of the roller 63, and pins 68 are symmetrically fixedly installed on the other side of the roller 63. A rubber block 69 is fixedly installed at one end of the pin 68. The pin 68 and the rubber block 69 are inserted into the inner wall of the T-shaped slot of the adjacent roller 63. By setting the rubber block 69, one end of the rubber block 69 is smaller, which makes it easier to use the good deformation ability of the rubber block 69 to insert the rubber block 69 and the pin 68 into the inner wall of the T-shaped slot. At the same time, the other end of the rubber block 69 is larger, which can limit the position between the pin 68 and the T-shaped slot, thereby connecting the adjacent rollers 63 and making it easy to disassemble the rollers 63. The number of rolling can be increased or decreased according to the actual situation of the leather.

[0027] Reference Figure 5 As shown, the adjustment assembly 7 includes a slider 71, which is slidably mounted on the inner wall of the perforated plate 62. An auxiliary plate 72 is fixedly mounted on one side of the slider 71. One of the rollers 63 is rotatably mounted on one side of the auxiliary plate 72 via a bearing. Bolts 73 are symmetrically threaded into one side of the auxiliary plate 72. By setting the slider 71, the roller 63 connected to the slider 71 can move on one side of the perforated plate 62. At the same time, by rotating the two bolts 73, one end of the bolt 73 abuts against one side of the auxiliary plate 72, thus fixing the roller 63. This facilitates the adjustment of the height of the roller 63 according to the thickness of the leather.

[0028] Reference Figure 5 As shown, the same spring 74 is fixedly installed on the top of the slider 71 and one side of the inner wall of the circular hole plate 62. A guide rod 75 is provided inside the spring 74. The slider 71 is slidably installed on the outer surface of the guide rod 75. The two ends of the guide rod 75 are respectively fixedly installed on both sides of the inner wall of the circular hole plate 62. By setting the spring 74, the spring 74 will move the slider 71 without the influence of external force, which can drive the roller 63 to move downward until the roller 63 abuts against the leather. This facilitates the quick adjustment of the roller 63 by the spring 74. At the same time, by setting the guide rod 75, the spring 74 can be limited to prevent the spring 74 from bending during deformation. A rubber plate 76 is symmetrically fixedly connected to one side of the circular hole plate 62. The rubber plate 76 has grooves evenly provided on one side. By setting the rubber plate 76 with grooves, the friction between the bolt 73 and the circular hole plate 62 can be increased, making the bolt 73 more firmly fixed to the roller 63.

[0029] Working principle: While the bottom of the limiting plate 65 abuts against the outer surface of the bottom extrusion band 3, it pushes the perforated plate 62 to slide on the outer surface of the threaded rod 61 until the two perforated plates 62 are located on both sides of the leather and are about to abut against it. Simultaneously, the bolt 73 is rotated, moving one end of the bolt 73 away from the auxiliary plate 72. The spring 74 then compresses the slider 71, causing the slider 71 to drive the roller 63 downwards until the rubber ring 66 on the outer surface of the roller 63 abuts against the top of the leather. Then, the bolt 73 is rotated in the opposite direction, causing one end of the bolt 73 to abut against the auxiliary plate 72. When the rubber plate 76 on one side of the plate 72 abuts, the roller 63 can be fixed. The limiting plate 65 and the roller 63 can limit the movement of the leather. At the same time, the roller 63 will not obstruct the movement of the leather, which helps to prevent the leather from shifting during movement. When it is necessary to add roller 63, the two rubber blocks 69 and the two pins 68 on one side of the roller 63 are respectively inserted into the inner wall of the two T-shaped slots 67 on the corresponding side of the roller 63. The rubber blocks 69 can limit the movement between the pins 68 and the T-shaped slots, thereby connecting the adjacent rollers 63.
