Description

Technical Field

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

[0002] During leather processing, a significant amount of free water is retained in the leather. This free water needs to be removed during subsequent processing, requiring appropriate equipment for treatment.

[0003] Traditional dewatering machines process leather by first operating the control box to activate the drive motor, which in turn starts the rotating rollers and drives the conveyor belt. Workers then place the leather on the conveyor belt, which moves it to the dewatering rollers. The rollers then roll and crush the leather to remove the water. However, in practice, it has been found that when the leather is placed on the conveyor belt, wrinkles appear. When the dewatering rollers roll and crush the leather, these wrinkles are compressed and overlapped, causing damage and breakage. This affects the processing effect and reduces the effectiveness and functionality of the dewatering machine. Utility Model Content

[0004] This utility model addresses the problem that when workers place leather on a conveyor belt, wrinkles appear, causing the wrinkles to overlap and be squeezed by the rolling and pressing of the dewatering roller, resulting in damage and breakage of the leather, affecting the processing effect, and reducing the effectiveness and functionality of the dewatering device. Therefore, this utility model proposes a leather dewatering device for leather processing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a leather squeezing device for leather processing, comprising a squeezing machine, a leveling device, and a fixing device. A control box is fixedly connected to the surface of the squeezing machine. A rotating roller is provided on the surface of the squeezing machine. A conveyor belt is rotatably connected to the arc surface of the rotating roller. A drive motor is provided on the surface of the squeezing machine. A squeezing roller is provided on the surface of the squeezing machine near the conveyor belt. The leveling device is mounted on the surface of the squeezing machine by means of the fixing device. The leveling device includes a mounting frame. The mounting frame is mounted on the surface of the squeezing machine by means of the fixing device. A mounting plate is slidably connected to the surface of the mounting frame. A scraper is fixedly connected to the side of the mounting plate near the conveyor belt. A screw is rotatably connected to the side of the mounting plate away from the scraper. A first gear is fixedly connected to the arc surface of the screw. The screw is threadedly connected to the surface of the mounting frame. A servo motor is fixedly connected to the surface of the mounting plate. A second gear is fixedly connected to the output end of the servo motor. The first gear and the second gear mesh.

[0006] The effects achieved by the above components are as follows: when the water squeezer is in use, it can better pre-treat the leather, make the leather flatter, ensure the flatness of the leather, and prevent wrinkles from forming, which could lead to cracking and damage during the water squeezing process. This further improves the use effect and functionality of the water squeezer.

[0007] Preferably, a stabilizing ring is fixedly connected to the surface of the mounting plate, and the stabilizing ring covers the arc surface of the first gear and the second gear.

[0008] The effect achieved by the above components is that, by setting up the stabilizing ring, the first gear and the second gear can be stably meshed, thereby making the screw rotate more stably and thus better driving the scraper to rise and fall.

[0009] Preferably, positioning blocks are fixedly connected to both sides of the surface of the mounting bracket, and the positioning blocks abut against the surface of the mounting plate.

[0010] The effect achieved by the above components is as follows: by setting the positioning block, when the mounting plate slides on the mounting frame under the drive of the servo motor, it can prevent the scraper from sliding down too much through contact with the auxiliary block, thereby better maintaining the distance from the conveyor belt and ensuring the flattening of leather wrinkles.

[0011] Preferably, an auxiliary sleeve is fitted onto the arc surface of the screw, and the auxiliary sleeve is fixedly connected to the surface of the mounting bracket. The auxiliary sleeve is a sponge sleeve.

[0012] The effect achieved by the above-mentioned components is that, by setting up the auxiliary sleeve, water stains splashed on the screw can be absorbed when the screw moves up and down in the mounting bracket, thereby ensuring a stable threaded connection between the screw and the mounting bracket.

[0013] Preferably, two assembly plates are fixedly connected to one side surface of the mounting plate, and an auxiliary roller is rotatably connected through the side of the two assembly plates that are close to each other.

[0014] The effect achieved by the above components is that, through the assembly plate and auxiliary rolling settings, when the leather is flattened and wrinkled by the scraper on the conveyor belt, the auxiliary roller can pre-squeeze the water from the leather by rolling in contact with it, thereby further improving the use effect and working efficiency of the dewatering machine.

[0015] Preferably, the fixing device includes two mounting frames, which are respectively fixedly connected to both sides of the surface of the dewatering machine. The two ends of the mounting frame are respectively inserted into the inner walls of the two fixed frames. Bolts are inserted through the surfaces of the two mounting frames, and the bolts are threaded through the arc surface of the mounting frame. Nuts are threadedly connected to the arc surface of the bolts.

[0016] The effect achieved by the above components is that the leveling device is easier to assemble during use and easier to inspect and maintain the components of the leveling device, thereby ensuring the normal use of the leveling device.

[0017] Preferably, an operating block is fixedly connected to the surface of the bolt, and the surface of the operating block is provided with a plurality of anti-slip protrusions.

[0018] The effect achieved by the above components is that the operation block makes the bolts more convenient and quick to use, thereby making the installation and disassembly of the mounting bracket more convenient and improving the ease of use of the fixing device.

[0019] Preferably, slots are provided on both sides of the surfaces of the two mounting frames, and a locking block is engaged with the inner wall of the slot. The locking block is fixedly connected to the arc surface of the mounting frame.

[0020] The effect achieved by the above components is that the locking mechanism of the slot and the locking block allows the mounting bracket to be inserted more stably into the inner wall of the mounting frame, thereby ensuring the stability of the leveling device and improving the performance of the fixing device.

[0021] In summary, the beneficial effects of this utility model are as follows:

[0022] When in use, a wringer can better pre-treat leather, making it smoother and preventing wrinkles that could cause breakage during the wringing process. This further improves the effectiveness and functionality of the wringer. Attached Figure Description

[0028] Reference Figure 1 As shown, this embodiment discloses a leather squeezing device for leather processing, including a squeezing machine 1, a flattening device 7, and a fixing device 8. A control box 5 is fixedly connected to the surface of the squeezing machine 1. A rotating roller 2 is provided on the surface of the squeezing machine 1. A conveyor belt 3 is rotatably connected to the arc surface of the rotating roller 2. A drive motor 4 is provided on the surface of the squeezing machine 1. A squeezing roller 6 is provided on the surface of the squeezing machine 1 near the conveyor belt 3. The flattening device 7 is mounted on the surface of the squeezing machine 1 by means of the fixing device 8.

[0029] Reference Figure 1 and Figure 2 as well as Figure 3As shown, this embodiment discloses a flattening device 7 including a mounting frame 71. The mounting frame 71 is mounted on the surface of the dewatering machine 1 by means of a fixing device 8. A mounting plate 72 is slidably connected to the surface of the mounting frame 71. A scraper 73 is fixedly connected to the side of the mounting plate 72 near the conveyor belt 3. A screw 74 is rotatably connected to the side of the mounting plate 72 away from the scraper 73. A first gear 75 is fixedly connected to the arc surface of the screw 74. The screw 74 is threadedly connected to the surface of the mounting frame 71. A servo motor 76 is fixedly connected to the surface of the mounting plate 72. A second gear 77 is fixedly connected to the output end of the servo motor 76. The first gear 75 and the second gear 77 mesh. However, when using the dewatering machine 1 to dewater the processed leather, the control box 5 is first operated to start the rotating roller 2 on the dewatering machine 1, thereby driving the conveyor belt 3 to run. Then, the leather is placed on the conveyor belt 3, and the mounting plate 74 is activated. The servo motor 76 on plate 72 rotates, and the second gear 77 on the output end of the servo motor 76 rotates. Because the first gear 75 and the second gear 77 mesh with each other, the screw 74 rotates, thus rotating the thread on the surface of the mounting bracket 71. At this time, the mounting plate 72 slides on the mounting bracket 71 until the scraper 73 on the mounting plate 72 just comes into contact with the leather on the conveyor belt 3. During the sliding contact between the leather and the scraper 73, the wrinkles on the leather can be smoothed out. Then, when the leather passes through the squeezing roller 6, the water in the leather can be squeezed out by the rolling and crushing of the squeezing roller 6. At this time, when the squeezing machine 1 is in use, it can better pre-treat the leather, make the leather flatter, ensure the flatness of the leather, and prevent wrinkles from forming, which could lead to overlapping and crushing damage during the squeezing process. This further improves the use effect and functionality of the squeezing machine 1.

[0030] Reference Figure 1 and Figure 2 as well as Figure 3 As shown, this embodiment discloses that a stabilizing ring 78 is fixedly connected to the surface of the mounting plate 72. The stabilizing ring 78 covers the arc surface of the first gear 75 and the second gear 77. By setting the stabilizing ring 78, the first gear 75 and the second gear 77 can be stably meshed, thereby making the screw 74 rotate more stably, thus better driving the scraper 73 to rise and fall. Positioning blocks 710 are fixedly connected to both sides of the surface of the mounting frame 71. The positioning blocks 710 abut against the surface of the mounting plate 72. By setting the positioning blocks 710, when the mounting plate 72 slides on the mounting frame 71 under the drive of the servo motor 76, it can prevent the scraper 73 from sliding down excessively by contacting the auxiliary blocks, thereby better maintaining the distance from the conveyor belt 3 and ensuring the flattening of leather wrinkles.

[0031] Reference Figure 1 and Figure 2 as well as Figure 3As shown, this embodiment discloses that an auxiliary sleeve 79 is sleeved on the arc surface of the screw 74. The auxiliary sleeve 79 is fixedly connected to the surface of the mounting frame 71. The auxiliary sleeve 79 is a sponge sleeve. By setting the auxiliary sleeve 79, when the screw 74 moves up and down with the mounting frame 71, the water stains splashed on the screw 74 can be absorbed, thereby ensuring a stable threaded connection with the mounting frame 71. Two assembly plates 711 are fixedly connected to one side surface of the mounting plate 72. An auxiliary roller 712 is rotatably connected through the side of the two assembly plates 711 that are close to each other. By setting the assembly plates 711 and the auxiliary roller, when the leather is flattened and wrinkled by the scraper 73 on the conveyor belt 3, the auxiliary roller 712 can pre-squeeze the water from the leather by rolling in contact with the leather, thereby further improving the use effect and working efficiency of the dewatering machine 1.

[0032] Reference Figure 1 and Figure 2 as well as Figure 4 As shown, this embodiment discloses a fixing device 8 including two mounting frames 81, which are respectively fixedly connected to both sides of the surface of the dewatering machine 1. The two ends of the mounting bracket 71 are respectively inserted into the inner walls of the two fixing frames. Bolts 82 are inserted through the surfaces of the two mounting frames 81, and the bolts 82 are threaded through the arc surface of the mounting bracket 71. Nuts 83 are threadedly connected to the arc surface of the bolts 82. When using the fixing device 8 to install and fix the leveling device 7, firstly, the two ends of the mounting bracket 71 are inserted into the inner walls of the mounting frames 81 fixedly connected to both sides of the surface of the dewatering machine 1. Then, the bolts 82 are inserted through the surface of the mounting frame 81, and the bolts 82 are rotated so that the bolts 82 are threadedly connected to the arc surface of the mounting bracket 71. Finally, the nuts 83 are threadedly connected to the bolts 82 until the nuts 83 are pressed against the surface of the mounting frame 81. At this time, the leveling device 7 is more convenient to assemble during use, and it is easier to inspect and maintain the components of the leveling device 7, thereby ensuring the normal use of the leveling device 7.

[0033] Reference Figure 1 and Figure 2 as well as Figure 4 As shown in the figure, this embodiment discloses that the surface of the bolt 82 is fixedly connected to the operating block 84. The surface of the operating block 84 is provided with several anti-slip protrusions. The operation block 84 makes the bolt 82 more convenient and quick to use, thereby making the installation and disassembly of the mounting bracket 71 more convenient and improving the ease of use of the fixing device 8. The two mounting frames 81 are respectively provided with slots 85 on both sides of their surfaces. The inner wall of the slots 85 is engaged with a block 86. The block 86 is fixedly connected to the arc surface of the mounting bracket 71. Through the engagement of the slots 85 and the block 86, the mounting bracket 71 is more stably inserted into the inner wall of the mounting frame 81, thereby ensuring the stability of the leveling device 7 and improving the use effect of the fixing device 8.

[0034] Working Principle: When using the dewatering machine 1 to dewater the processed leather, firstly, the control box 5 is operated to start the drive motor 4 on the dewatering machine 1, which drives the rotating roller 2 to start running, thereby driving the conveyor belt 3 to operate. Then, the leather is placed on the conveyor belt 3. By starting the servo motor 76 on the mounting plate 72, the second gear 77 on the output end of the servo motor 76 rotates. Because the first gear 75 and the second gear 77 mesh with each other, the screw 74 will rotate, thereby rotating the threaded surface on the mounting frame 71. At this time, the mounting plate 72 will rotate on the mounting frame 71. The leather slides until the scraper 73 on the mounting plate 72 comes into contact with the leather on the conveyor belt 3. During the sliding contact between the leather and the scraper 73, the wrinkles on the leather can be smoothed out. Then, when the leather passes through the squeezing roller 6, the water in the leather can be squeezed out by the rolling and pressing of the squeezing roller 6. At this time, when the squeezing machine 1 is in use, it can better pre-treat the leather, make the leather flatter, ensure the flatness of the leather, and prevent wrinkles from forming, which could cause overlapping and squeezing damage during the squeezing process. This further improves the use effect and functionality of the squeezing machine 1.

[0035] When installing and fixing the leveling device 7 using the fixing device 8, first insert both ends of the mounting bracket 71 into the inner wall of the mounting frame 81 fixedly connected to both sides of the surface of the wringer 1. Then, pass the bolt 82 through the surface of the mounting frame 81 and rotate the bolt 82 so that the bolt 82 is threaded onto the arc surface of the mounting bracket 71. Finally, thread the nut 83 onto the bolt 82 until the nut 83 contacts and presses against the surface of the mounting frame 81. At this time, the leveling device 7 is more convenient to assemble and easier to inspect and maintain the components of the leveling device 7, thereby ensuring the normal use of the leveling device 7.
