Description

Technical Field

[0001] This utility model relates to a leather processing liming treatment device, belonging to the field of liming technology. Background Technology

[0002] Lime impregnation is an important process in leather manufacturing. It involves using a lime water emulsion of a certain concentration to increase the weight and thickness of the raw leather hide after soaking and rehydration, slightly shortening its length while keeping its surface area almost unchanged. The purpose of liming is to remove the interfibrous matrix within the hide, weaken the connection between the hair, epidermis, and dermis, modify elastic fibers, and break down muscle tissue, thus facilitating the action of other materials on the hide in subsequent processes. Simultaneously, it saponifies the oils in the raw hide, removing some of the internal oils and achieving a certain degree of degreasing. Furthermore, it can break some secondary bonds in the collagen, allowing the collagen fibers to become appropriately loose and releasing more active collagen groups, while also removing the hair and epidermis.

[0003] Chinese Patent Publication No. CN 212925068 U discloses a leather liming device, including an upper cover plate, a lifting hydraulic press, support columns, a base plate, pads, a processing chamber, a drain pipe, and a control device. The pads are located at both ends of the lower base plate, the support columns are located at both ends of the top of the base plate, the upper cover plate is located at the top of the support columns, the lifting hydraulic press is located below the center of the upper cover plate, the control device is located below the lifting hydraulic press, the processing chamber is located at the center of the top of the base plate, and is directly below the control device. The drain pipe extends through the lower side of the processing chamber. This utility model belongs to the field of leather production technology, specifically referring to a leather liming device that uses a control device to control the immersion of leather in liming liquid and press the leather to accelerate the liming speed and improve efficiency. The aforementioned device mainly uses a lever to move the compression block to compress the leather. However, in actual use, since there is only one compression block, it often takes a lot of time to compress larger pieces of leather. In addition, the device is not equipped with a structure to fix the leather, which may cause the leather to fall out of the compression block during compression, making it inconvenient for operators to use.

[0004] Therefore, a leather processing liming treatment device is proposed. Utility Model Content

[0005] In view of this, the present invention provides a leather processing liming device to solve or alleviate the technical problems existing in the prior art, and at least provides a beneficial option.

[0006] The technical solution of this utility model is achieved as follows: a leather processing liming treatment device, comprising: A liming assembly includes a water tank, a support table fixedly installed in the inner cavity of the water tank, an inlet valve fixedly installed on the rear side of the water tank, a drain valve fixedly installed on the rear side of the water tank, a support frame fixedly installed on the top of the water tank, a base plate fixedly installed on the bottom of the water tank, mounting brackets fixedly installed around the top of the support table, threaded screws connected to the inner surfaces of the four mounting brackets, knobs fixedly installed on the top of the four screws, and pressure blocks movably connected to the bottom of the four screws.

The connecting rods are slidably connected to the inner cavities of the three frames. Vertical rods are fixedly mounted on the bottom of each of the three frames. A lifting plate is fixedly mounted on the other end of each vertical rod. A first extrusion block is fixedly mounted on the bottom of each lifting plate. A second extrusion block is fixedly mounted on the top of each support table.

[0007] More preferably, driven sprockets are fixedly connected to the outer sides of both turntables, and chains are meshed with the surfaces of both driven sprockets and both driving sprockets.

[0008] More preferably, both the first extrusion block and the second extrusion block are arc-shaped, and neither the first extrusion block nor the second extrusion block is in the same vertical direction.

[0009] More preferably, guide rods are fixedly installed on the top of each of the three frames, and guide grooves are opened on the top of each support frame. The guide rods pass through the inner cavity of the guide grooves and extend to the top of the support frame.

[0014] The present invention has the following advantages due to the adoption of the above technical solution: I. This utility model, by setting up an impregnation assembly, uses the rotation of a knob to cause the screw to move the lower pressure block downwards, thereby pressing and fixing the leather. This effectively avoids displacement of the leather when the second and first pressure blocks are close to each other, ensuring the stability of the squeezing and cleaning of residues on the leather surface. It is also convenient for operators to use. By setting up the squeezing assembly, through the output of a bidirectional motor, the turntable drives the connecting rod to move circumferentially, which in turn drives the lifting plate to move up and down reciprocally. This, in turn, enables the first pressure block to move up and down reciprocally to squeeze the leather, achieving the squeezing and cleaning of residues on the leather surface. By increasing the speed of cleaning residues on the leather surface, the quality and speed of the impregnation process are improved.

[0015] II. This utility model, by setting guide grooves and guide rods, can guide the direction of frame lifting and lowering, preventing it from deviating during movement and thus affecting the squeezing of leather. By setting support blocks, it can support the drive shaft, preventing it from falling off after long-term use. By setting limit rods, it can limit the lower pressure block, preventing it from rotating synchronously with the screw. By setting anchor bolts, it can stabilize the entire equipment, preventing the equipment from shaking due to accidental collisions.

[0020] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0021] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0022] Example 1 like Figure 1-6 As shown, this utility model embodiment provides a leather processing liming treatment apparatus, including: The immersion assembly 1 includes a water tank 101. A support table 102 is fixedly installed in the inner cavity of the water tank 101. An inlet valve 103 and a drain valve 104 are fixedly installed on the rear side of the water tank 101. A support frame 105 is fixedly installed on the top of the water tank 101. A base plate 106 is fixedly installed on the bottom of the water tank 101. Mounting brackets 107 are fixedly installed on all four sides of the top of the support table 102. Screws 108 are threadedly connected to the inner surfaces of the four mounting brackets 107. Knobs 109 are fixedly installed on the top of the four screws 108. A pressure block 110 is movably connected to the bottom of the four screws 108. The extrusion assembly 2 includes a bidirectional motor 201, which is fixedly mounted on the top of the support frame 105. Drive shafts 202 are fixedly connected to the output ends of both the front and rear sides of the bidirectional motor 201. A drive sprocket 203 is fixedly connected to the other end of each drive shaft 202. Turntables 206 are movably connected to the front and rear sides of the surface of the drain valve 104. Connecting rods 207 are fixedly mounted on the inner sides of the two turntables 206. Frames 208 are provided on the top of each water tank 101. The connecting rods 207 are slidably connected to the inner cavities of the three frames 208. Vertical rods 209 are fixedly installed at the bottom of each support table 102. Lifting plates 210 are fixedly installed at the other end of each vertical rod 209. First pressing blocks 211 are fixedly installed at the bottom of each lifting plate 210. Second pressing blocks 212 are fixedly installed at the top of each support table 102. Driven sprockets 204 are fixedly connected to the outer sides of each turntable 206. Chains 205 are meshed between the surfaces of the two driven sprockets 204 and the two driving sprockets 203. The first pressing block 211 and the second pressing block 212 are both arc-shaped. The first pressing block 211 and the second pressing block 212 are not in the same vertical direction.

[0023] By setting up the ash-soaking component 1, the rotation of the knob 109 causes the screw 108 to drive the lower pressure block 110 downward, thereby pressing and fixing the leather. This effectively prevents the leather from shifting when the second pressing block 212 and the first pressing block 211 are pressed close to each other, ensuring the stability of the pressing and cleaning of residues on the leather surface and making it convenient for operators to use. By setting up the pressing component 2, the output of the bidirectional motor 201 causes the turntable 206 to drive the connecting rod 207 to move circumferentially, which in turn causes the lifting plate 210 to move up and down reciprocally. This, in turn, enables the first pressing block 211 to move up and down reciprocally to press the leather, thus achieving the pressing and cleaning of residues on the leather surface. By increasing the speed of cleaning residues on the leather surface, the quality and speed of the ash-soaking process are improved.

[0024] Example 2 In one embodiment, guide rods 213 are fixedly installed on the top of each of the three frames 208, and guide grooves 214 are opened on the top of each support frame 105. The guide rods 213 pass through the inner cavity of the guide grooves 214 and extend to the top of the support frame 105. Support blocks 215 are movably connected to the surfaces of the two drive shafts 202 through bearings. The bottoms of the two support blocks 215 are fixedly installed on the front and rear sides of the top of the support frame 105. A control switch 216 is fixedly installed on the front side of the support frame 105. The output end of the control switch 216 is electrically connected to the input end of the bidirectional motor 201. Limit rods 111 are fixedly installed on the top of each of the four pressing blocks 110. The limit rods 111 pass through the inner surface of the mounting frame 107 and extend to the top of the mounting frame 107. Anchor bolts 112 are threaded around the top of the base plate 106. The bottom of the anchor bolts 112 is threaded to the ground.

[0025] By setting guide groove 214 and guide rod 213, the direction of frame 208 during lifting can be guided to avoid deviation during movement, which would affect the squeezing of leather. By setting support block 215, the transmission shaft 202 can be supported to prevent it from falling off after long-term use. By setting limit rod 111, the lower pressure block 110 can be limited to prevent it from rotating synchronously with screw 108. By setting anchor bolt 112, the overall equipment can be stabilized to prevent the equipment from shaking due to accidental collision.

[0026] In operation, this invention works as follows: First, the ash-impregnating liquid is injected into the water tank 101 through the water inlet valve 103. Then, the leather is placed on top of the support table 102. At this time, the second pressing block 212 is at the bottom of the leather, stretching it. Then, by rotating the knob 109, the knob 109 drives the screw 108 to rotate synchronously. The screw 108 drives the lower pressing block 110 to move downward, pressing and fixing the leather. Then, through the output of the bidirectional motor 201, the drive shaft 202 drives... The driving sprocket 203 rotates, and through the cooperation of the driving sprocket 203 and the chain 205, the chain 205 drives the driven sprocket 204 and the turntable 206 to rotate synchronously. At this time, the turntable 206 drives the connecting rod 207 to move in the circumferential direction in the inner cavity of the frame 208, so that the frame 208 drives the vertical rod 209 and the lifting plate 210 to move up and down reciprocally. At this time, the lifting plate 210 drives the first pressing block 211 to press down reciprocally, realizing the pressing and cleaning of residues on the leather surface.

Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model.
