Description

Technical Field

[0001] This invention belongs to the field of leather cutting, specifically relating to a leather cutting device for leather shoe processing. Background Technology

[0002] Leather cutting is a crucial process for precisely cutting raw or finished leather into designed shapes. Traditional methods rely on die-cutting and manual cutting, resulting in low material utilization and difficulty in handling imperfections in natural leather. Modern technology has evolved to employ high-definition projection positioning, visual recognition, and automatic nesting systems, combined with high-frequency vibrating blades or laser cutting, to achieve efficient, precise, and imperfection-avoiding intelligent cutting.

[0003] Patent CN221028497U discloses a cutting device for leather processing, belonging to the field of leather processing technology. It includes a cutting table with a feeding roller rotatably mounted at one end. A cutting mechanism is provided on the cutting table, comprising a driving component, a pressing component, and a cutting component. The driving component includes two cylinders and two fixed seats. The two cylinders are symmetrically fixed to the two side walls of the cutting table, and the two fixed seats are respectively fixed to the extended ends of the two cylinders. A pressing component is symmetrically arranged between the two fixed seats. The cutting component is fixed between the two fixed seats and located between the two pressing components. This patent, by setting a driving component and a pressing component on the cutting table, can prevent leather position shift and cut edge tilting during leather cutting, improving the accuracy of leather cutting. Although this device solves the aforementioned problems, it suffers from leather wrinkling and bulging during cutting, affecting the cutting quality. Therefore, a leather cutting device for shoe processing is proposed to solve the aforementioned problems. Summary of the Invention

[0004] The purpose of this invention is to provide a leather cutting device for shoe processing, so as to solve the problem that wrinkles and bulges in leather during the cutting process affect the cutting quality.

[0005] To achieve the above objectives, the present invention provides a leather cutting device for shoe processing, including a bottom connecting seat, a limiting partition plate fixedly connected to the top of the bottom connecting seat, a leather cutting knife slidably connected to the outer wall of the limiting partition plate, a stretching mechanism provided at the top of the bottom connecting seat, a cleaning mechanism provided at the top of the bottom connecting seat, a collecting mechanism provided at the left side of the bottom connecting seat, a shaft wheel provided at the left side of the collecting mechanism, and the leather material being wound around the outer circumference of the shaft wheel; The stretching mechanism includes a limiting groove, a sliding block, a pull rod, a bidirectional screw, and a hollow rod. The limiting groove is formed on the inner wall of the limiting isolation plate. The sliding block is slidably connected to the inner wall of the limiting groove. The pull rod is rotatably connected to the inner wall of the sliding block. The bidirectional screw is fixedly connected to the outer wall of the pull rod. The hollow rod is slidably connected to the top of the bottom connecting seat and is in contact with the limiting isolation plate.

[0006] In one or more embodiments of the present invention, the stretching mechanism further includes a bearing seat, a top slider, a first helical rod, and an upper clamping seat. The bearing seat is movably connected to the outer circumferential surface of the bidirectional screw. The top slider is slidably connected to the inner wall of the hollow rod. The bearing seat and the hollow rod are slidably connected. The first helical rod is rotatably connected to the inner wall of the top slider. The upper clamping seat is movably connected to the outer circumferential surface of the first helical rod. The upper clamping seat and the hollow rod are slidably connected.

[0007] In one or more embodiments of the present invention, the stretching mechanism further includes a bottom clamping plate, a second spiral rod, and a horizontal fixing lug. The bottom clamping plate is fixedly connected to the outer wall of the shaft seat, and the bottom clamping plate is slidably connected to the hollow rod. The horizontal fixing lug is fixedly connected to the outer wall of the bottom connecting seat, the second spiral rod is rotatably connected to the outer wall of the bottom connecting seat, the horizontal fixing lug is fixedly connected to the hollow rod, and the horizontal fixing lug is movably connected to the outer circumferential surface of the second spiral rod. A motor is provided on the left side of the second spiral rod. Before use, the leather is wound around the outer circumference of the axle wheel. Before cutting, one end of the leather is pulled and placed between the bottom clamp and the upper clamp. Then, the rotating screw drives the upper clamp downward under the limitation of the hollow rod through the spiral groove on the circumference. During the movement, the upper clamp moves closer to the bottom clamp, clamping and fixing the leather. Then, the pull rod is pulled to move the hollow rod to the other end of the device. The movement of the hollow rod causes the leather to unfold on the top of the bottom connecting seat, so that the leather material is stretched and flattened during cutting, avoiding wrinkles and bulges during the cutting process. At the same time, it can also keep the cutting smooth and improve the utilization rate of the leather. After the leather is clamped by the upper clamp and the bottom clamp, the rotating pull rod drives the double screw to rotate. The rotation of the double screw drives the bottom clamp to move under the limitation of the hollow rod through the spiral groove on the circumference. The movement of the bottom clamp causes the clamped leather to unfold to both sides, so that the device can adapt to leather of different lateral dimensions and also avoid wrinkles and bulges in the lateral dimensions of the leather.

[0008] In one or more embodiments of the present invention, the cleaning mechanism further includes a fixed base plate, a vertical L-shaped frame, a spiral rod, and a rotating column. The fixed base plate is fixedly connected to the outer wall of the limiting isolation plate, the vertical L-shaped frame is slidably connected to the inner wall of the limiting isolation plate, the spiral rod is rotatably connected to the top of the fixed base plate, the vertical L-shaped frame is movably connected to the outer circumferential surface of the spiral rod, and the rotating column is fixedly connected to the top of the spiral rod.

[0009] In one or more embodiments of the present invention, the cleaning mechanism further includes a limiting post, a lateral moving block, a vertical connecting frame, and a horizontal pressing column. The limiting post is fixedly connected to the top of the base plate, the vertical L-frame is slidably connected to the limiting post, the lateral moving block is fixedly connected to the outer wall of the vertical L-frame, the vertical connecting frame is fixedly connected to the inner wall of the lateral moving block, and the horizontal pressing column is fixedly connected to the bottom of the vertical connecting frame.

[0010] In one or more embodiments of the present invention, the cleaning mechanism further includes a sliding connecting rod, a flexible joint, a horizontal pressure column, and a cleaning roller brush. The sliding connecting rod is slidably connected to the inner wall of the horizontal pressure column, the flexible joint is fixedly connected to the top of the sliding connecting rod, and the flexible joint is connected to the horizontal pressure column by a spring. The horizontal pressure column is fixedly connected to the bottom of the sliding connecting rod, and the cleaning roller brush is rotatably connected to the inner wall of the vertical L-frame. The leather material is located on the movement trajectory of the cleaning roller brush. Before use, the leather is wound around the outer circumference of the axle wheel. Before cutting, one end of the leather is pulled and placed between the bottom clamp and the upper clamp. Then, the rotating screw drives the upper clamp downward under the limitation of the hollow rod through the spiral groove on the circumference. During the movement, the upper clamp moves closer to the bottom clamp, clamping and fixing the leather. Then, the pull rod is pulled to move the hollow rod to the other end of the device. The movement of the hollow rod causes the leather to unfold on the top of the bottom connecting seat, so that the leather material is stretched and flattened during cutting, avoiding wrinkles and bulges during the cutting process. At the same time, it can also keep the cutting smooth and improve the utilization rate of the leather. After the leather is clamped by the upper clamp and the bottom clamp, the rotating pull rod drives the double screw to rotate. The rotation of the double screw drives the bottom clamp to move under the limitation of the hollow rod through the spiral groove on the circumference. The movement of the bottom clamp causes the clamped leather to unfold to both sides, so that the device can adapt to leather of different lateral dimensions and also avoid wrinkles and bulges in the lateral dimensions of the leather.

[0011] In one or more embodiments of the present invention, the collection mechanism includes a collection chamber, a hinged door, and a connecting block. The collection chamber is fixedly connected to the outer wall of the bottom connecting seat, the hinged door is rotatably connected to the inner wall of the collection chamber, and the connecting block is fixedly connected to the outer wall of the bottom connecting seat.

[0012] In one or more embodiments of the present invention, the collection mechanism further includes a water tank, a bottom sealing plate, and a water transfer trough. The water tank is fixedly connected to the outer wall of the connecting block, the bottom sealing plate is fixedly connected to the bottom of the water tank, the water transfer trough is fixedly connected to the outer wall of the drive shaft, and the water transfer trough is slidably connected to the bottom sealing plate.

[0013] In one or more embodiments of the present invention, the collection mechanism further includes a drive shaft and a sieve plate, the drive shaft being located at the bottom of the bottom sealing plate, and the sieve plate being fixedly connected to the inner wall of the collection chamber. As the leather is pulled, it causes the axle to rotate. This rotation, via a pulley system, drives the drive shaft, which in turn rotates the water tank. The water tank's rotation evenly disperses the clean water from inside the tank onto the leather's surface. Then, a cleaning roller brush ensures even contact between the water and the leather. Leather, typically dry and brittle when removed from the warehouse, softens and regains its resilience with the added water. This reduces the likelihood of chipping or cracking during cutting, making the leather more durable. After the leather is cut, the axle rotates in the opposite direction, collecting the cut leather waste. The finished leather products fall into the collection chamber and remain on top of the sieving plate. Excess water in the water tank also falls into the collection chamber. Under the isolation of the sieving plate, the clean water drips to the bottom of the sieving plate, while the finished products remain on top of the sieving plate. The finished products remaining on top of the bottom connecting seat pull the lever to push the remaining finished products on top of the sieving plate, facilitating manual collection of the finished products.

[0014] Compared with the prior art, the beneficial effect of the present invention is that, through

[0015] 1. This invention uses a base clamp, a pull rod, and a perforated rod to clamp and fix the leather material. Then, pulling the pull rod moves the perforated rod to the other end of the device. The movement of the perforated rod causes the leather material to unfold on the top of the base, thereby stretching and flattening the leather material during cutting, preventing wrinkles and bulges during the cutting process, while also maintaining smooth cutting and improving the utilization rate of the leather material. The movement of the base clamp causes the clamped leather material to unfold to both sides, so that the device can adapt to leather materials of different lateral dimensions, and at the same time, it can also prevent wrinkles and bulges in the lateral dimensions of the leather material.

[0016] 2. In this invention, with the cooperation of the horizontal pressure lower column, the vertical L-frame, and the horizontal pressure upper column, the vertical L-frame moves downward under the limitation of the limiting partition plate. The downward movement of the vertical L-frame drives the cleaning roller brush to move downward, so that the cleaning roller brush comes into contact with the leather. Then, the hollow rod moves and pulls the leather to bring the leather into contact with the cleaning roller brush, so that the cleaning roller brush wipes away the sand and dust on the surface of the leather, preventing the dust on the surface of the leather from scratching the leather surface during cutting. The downward movement of the horizontal pressure upper column drives the horizontal pressure lower column to move downward, and the downward movement of the horizontal pressure lower column fixes and squeezes the edge of the leather, preventing the leather from being too wide in the lateral length, which would cause the leather edge to fray, spread out, or delaminate during the cutting process.

[0017] 3. In this invention, with the cooperation of the rotating water tank, the cleaning roller brush, and the water tank, the water inside the water tank is evenly dispersed on the surface of the leather during the rotation of the water tank. Then, under the cleaning of the cleaning roller brush, it is evenly contacted with the leather. When the leather is taken out of the warehouse, it is usually dry and brittle. The introduction of water softens the leather and restores its toughness, reducing the probability of chipping and cracking during the cutting process, making the leather easier to cut.

Detailed Implementation

[0027] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0028] Please see Figures 1-7One embodiment of the present invention is: a leather cutting device for shoe processing, including a bottom connecting seat 1, a limiting partition plate 4 fixedly connected to the top of the bottom connecting seat 1, a leather cutting knife 2 slidably connected to the outer wall of the limiting partition plate 4, a stretching mechanism 3 provided at the top of the bottom connecting seat 1, a cleaning mechanism 5 provided at the top of the bottom connecting seat 1, a collecting mechanism 6 provided at the left side of the bottom connecting seat 1, a shaft wheel 7 provided at the left side of the collecting mechanism 6, and leather 8 wound around the outer circumference of the shaft wheel 7; The stretching mechanism 3 includes a limiting groove 301, a sliding block 302, a pull rod 303, a bidirectional screw 304, and a hollow rod 305. The limiting groove 301 is formed on the inner wall of the limiting isolation plate 4. The sliding block 302 is slidably connected to the inner wall of the limiting groove 301. The pull rod 303 is rotatably connected to the inner wall of the sliding block 302. The bidirectional screw 304 is fixedly connected to the outer wall of the pull rod 303. The hollow rod 305 is slidably connected to the top of the bottom connecting seat 1 and is in contact with the limiting isolation plate 4.

[0029] The stretching mechanism 3 also includes a bearing seat 306, a top slider 307, a spiral rod 308, and an upper clamp 309. The bearing seat 306 is movably connected to the outer circumferential surface of the bidirectional screw 304. The top slider 307 is slidably connected to the inner wall of the hollow rod 305. The bearing seat 306 and the hollow rod 305 are slidably connected. The spiral rod 308 is rotatably connected to the inner wall of the top slider 307. The upper clamp 309 is movably connected to the outer circumferential surface of the spiral rod 308. The upper clamp 309 and the hollow rod 305 are slidably connected.

[0030] The stretching mechanism 3 also includes a bottom clamping plate 310, a second spiral rod 311, and a horizontal fixing ear 312. The bottom clamping plate 310 is fixedly connected to the outer wall of the bearing seat 306. The bottom clamping plate 310 is slidably connected to the hollow rod 305. The horizontal fixing ear 312 is fixedly connected to the outer wall of the bottom connecting seat 1. The second spiral rod 311 is rotatably connected to the outer wall of the bottom connecting seat 1. The horizontal fixing ear 312 is fixedly connected to the hollow rod 305. The horizontal fixing ear 312 is movably connected to the outer circumferential surface of the second spiral rod 311. A motor is provided on the left side of the second spiral rod 311. The leather material 8 is clamped and fixed, and then the pull rod 303 is pulled to move the hollow rod 305 to the other end of the device. The movement of the hollow rod 305 causes the leather material 8 to unfold on the top of the bottom connecting seat 1, so that the leather material is stretched and flattened during cutting, avoiding wrinkles and bulges in the leather during the cutting process, while also keeping the cutting smooth and improving the utilization rate of the leather material 8. The bottom clamping plate 310 moves to cause the clamped leather material 8 to unfold to both sides, so that the device can adapt to leather materials 8 of different lateral dimensions, and at the same time avoid wrinkles and bulges in the lateral dimensions of the leather material 8.

[0031] The cleaning mechanism 5 also includes a fixed base plate 501, a vertical L-shaped frame 502, a spiral rod 503, and a rotating column 504. The fixed base plate 501 is fixedly connected to the outer wall of the limiting isolation plate 4, the vertical L-shaped frame 502 is slidably connected to the inner wall of the limiting isolation plate 4, the spiral rod 503 is rotatably connected to the top of the fixed base plate 501, the vertical L-shaped frame 502 is movably connected to the outer circumferential surface of the spiral rod 503, and the rotating column 504 is fixedly connected to the top of the spiral rod 503.

[0032] The cleaning mechanism 5 also includes a limiting post 505, a lateral moving block 506, a vertical connecting frame 507, and a horizontal pressing column 508. The limiting post 505 is fixedly connected to the top of the fixed base plate 501. The vertical L-frame 502 is slidably connected to the limiting post 505. The lateral moving block 506 is fixedly connected to the outer wall of the vertical L-frame 502. The vertical connecting frame 507 is fixedly connected to the inner wall of the lateral moving block 506. The horizontal pressing column 508 is fixedly connected to the bottom of the vertical connecting frame 507.

[0033] The cleaning mechanism 5 also includes a sliding connecting rod 509, a flexible joint 510, a horizontal pressure column 511, and a cleaning roller brush 512. The sliding connecting rod 509 is slidably connected to the inner wall of the horizontal pressure column 508. The flexible joint 510 is fixedly connected to the top of the sliding connecting rod 509. The flexible joint 510 and the horizontal pressure column 508 are connected by a spring. The horizontal pressure column 511 is fixedly connected to the bottom of the sliding connecting rod 509. The cleaning roller brush 512 is rotatably connected to the inner wall of the vertical L-frame 502. The leather 8 is located on the movement trajectory of the cleaning roller brush 512. The spiral groove drives the vertical L-frame 502 to move downward under the limitation of the isolation plate 4. The downward movement of the vertical L-frame 502 drives the cleaning roller brush 512 to move downward, so that the cleaning roller brush 512 comes into contact with the leather material 8. Then the hollow rod 305 moves and pulls the leather material 8 to bring the leather material 8 into contact with the cleaning roller brush 512, so that the cleaning roller brush 512 wipes away the sand and dust on the surface of the leather material 8, preventing the dust on the surface of the leather material 8 from scratching the leather surface during cutting. The horizontal pressure upper column 508 moves downward, driving the horizontal pressure lower column 511 to move downward. The horizontal pressure lower column 511 moves downward to fix and squeeze the edge of the leather material 8, preventing the horizontal length of the leather material 8 from being too wide, which would cause the leather edge to fray, spread out, or delaminate during the cutting process.

[0034] Working principle: Before use, the leather material 8 is wound around the outer circumference of the shaft wheel 7. Before the leather is cut, one end of the leather is pulled and placed between the bottom clamping plate 310 and the upper clamping seat 309. Then, the rotating spiral rod 308 drives the upper clamping seat 309 to move downward under the limitation of the hollow rod 305 through the spiral groove on the circumference. During the movement, the upper clamping seat 309 moves closer to the bottom clamping plate 310, clamping and fixing the leather material 8. Then, the pull rod 303 is pulled to move the hollow rod 305 to the other end of the device. The movement of the hollow rod 305 causes the leather material 8 to unfold on the top of the bottom connecting seat 1, thereby allowing the leather material to be cut. The leather is stretched and flattened during cutting to prevent wrinkles and bulges during the cutting process, while also ensuring smooth cutting and improving the utilization rate of the leather material 8. After the leather material 8 is clamped by the upper clamp 309 and the bottom clamp 310, the rotating pull rod 303 drives the bidirectional screw 304 to rotate. The rotation of the bidirectional screw 304 drives the bottom clamp 310 to move under the limitation of the hollow rod 305 through the spiral groove on the circumferential surface. The movement of the bottom clamp 310 causes the clamped leather material 8 to unfold to both sides, so that the device can adapt to leather materials 8 with different lateral dimensions, and at the same time, it can also prevent wrinkles and bulges in the lateral dimensions of the leather material 8.

[0035] Before the leather material 8 is pulled by the hollow rod 305, the rotating column 504 drives the vertical L-shaped frame 502 to move downward under the limitation of the limiting plate 4 through the spiral groove on the circumferential surface. The downward movement of the vertical L-shaped frame 502 drives the cleaning roller brush 512 to move downward, so that the cleaning roller brush 512 comes into contact with the leather material 8. Then the hollow rod 305 moves and pulls the leather material 8 to bring the leather material 8 into contact with the cleaning roller brush 512, so that the cleaning roller brush 512 can wipe away the sand and dust on the surface of the leather material 8, preventing the dust on the surface of the leather material 8 from being exposed during cutting. The scratching of the leather surface of the leather material 8 causes damage to the leather. When the cleaning roller brush 512 moves downward, it drives the horizontal block 506 and the vertical connecting frame 507 to move downward. The downward movement of the vertical connecting frame 507 drives the horizontal pressure upper column 508 to move downward. The downward movement of the horizontal pressure upper column 508 drives the horizontal pressure lower column 511 to move downward. The downward movement of the horizontal pressure lower column 511 fixes and squeezes the edge of the leather material 8 to prevent the horizontal length of the leather material 8 from being too wide, which would cause the leather edge to fray, spread out, or delaminate during the cutting process.

[0036] Please see Figures 1-7 Based on the above embodiments, in another embodiment of the present invention, the collection mechanism 6 includes a central chamber 601, a hinge door 602, and a connecting block 607. The central chamber 601 is fixedly connected to the outer wall of the bottom connecting seat 1, the hinge door 602 is rotatably connected to the inner wall of the central chamber 601, and the connecting block 607 is fixedly connected to the outer wall of the bottom connecting seat 1.

[0037] The collection mechanism 6 also includes a water tank 603, a bottom sealing plate 604, and a water transfer trough 605. The water tank 603 is fixedly connected to the outer wall of the connecting block 607, the bottom sealing plate 604 is fixedly connected to the bottom of the water tank 603, and the water transfer trough 605 is fixedly connected to the outer wall of the drive shaft 606. The water transfer trough 605 and the bottom sealing plate 604 are slidably connected.

[0038] The collection mechanism 6 also includes a drive shaft 606 and a sieve plate 608. The drive shaft 606 is located at the bottom of the bottom sealing plate 604, and the sieve plate 608 is fixedly connected to the inner wall of the collection chamber 601. During the rotation of the water tank 605, the clean water inside the water tank 603 is evenly dispersed onto the surface of the leather material 8. Then, under the cleaning of the cleaning roller brush 512, it is evenly contacted with the leather material 8. When the leather material 8 is taken out of the warehouse, it is usually dry and brittle. The intervention of clean water makes the leather material 8 soft and restores its toughness, reducing the probability of chipping and cracking during the cutting process, making the leather material 8 easier to cut.

[0039] Working principle: As the leather 8 is pulled, it drives the shaft wheel 7 to rotate. The rotation of the shaft wheel 7, via the pulley assembly, drives the drive shaft 606 to rotate. The rotation of the drive shaft 606, in turn, drives the water tank 605 to rotate. During the rotation of the water tank 605, the clean water inside the water chamber 603 is evenly dispersed onto the surface of the leather 8. Subsequently, under the cleaning brush 512, the water is evenly applied to the leather 8. When the leather 8 is taken out of the warehouse, it is usually dry and brittle. The introduction of clean water softens the leather 8 and restores its toughness, reducing the probability of chipping and cracking during cutting, making the leather 8 more durable. After the leather material 8 is cut, the shaft wheel 7 rotates in the opposite direction. After the shaft wheel 7 rotates, the cut leather waste is collected. The finished leather product after cutting will fall into the interior of the collection chamber 601 and stay on the top of the sieve plate 608. Excess water in the water chamber 603 will also fall into the interior of the collection chamber 601. Under the isolation of the sieve plate 608, the clean water will drip down to the bottom of the sieve plate 608. The finished product will stay on the top of the sieve plate 608. The finished product stuck on the top of the bottom connecting seat 1 pulls the lever 303 to push the finished product remaining on the top of the bottom connecting seat 1 to the top of the sieve plate 608, which is convenient for manual collection of the finished product.
