Description

Technical Field

[0001] The present application relates to the technical field of belt production, and in particular to a simple leather cutting machine. Background Art

[0002] As a classic and practical accessory, leather belts not only secure clothing but also add sophistication and style to any outfit with their unique texture and grain. During the production process, a cutting device is first used to segment the leather, ensuring the correct size of each section. This facilitates subsequent processing, ultimately completing the production of the leather belt.

[0003] Existing manual leather cutting machines primarily consist of a workbench, a movable crossbeam, a slide, a baffle, and a cutter. The movable crossbeam is mounted on the workbench, the slide slides outside the movable crossbeam, the cutter is mounted at the bottom of the slide for cutting the leather, and the baffle is mounted on the upper side of the workbench for aligning the leather edges. To use the machine, the leather is first placed on the workbench, with one end of the leather passed through the bottom of the movable crossbeam and resting against one side of the baffle. The movable crossbeam is then pressed down to compress the leather. The slide is then pushed linearly along the movable crossbeam, causing the cutter to cut through the leather, completing the cut.

[0004] In the prior art, the cut leather needs to be taken out and placed in a specific place for subsequent sorting or entering the next processing step. This requires manual processing, which is time-consuming and labor-intensive. In addition, there is a lack of linkage between the various components, and the operation steps are cumbersome. Each step needs to be completed manually one by one, which not only increases labor intensity but also reduces the efficiency of leather cutting. Summary of the Invention

[0005] In order to improve the convenience of cutting machine operation and improve the efficiency of leather cutting, the present application provides a simple leather cutting machine.

[0006] The present application provides a simple leather cutting machine that adopts the following technical solutions: The adjusting device is mounted on a top side of the workbench, and the adjusting device is mounted on a bottom side of the workbench to adjust the position of the leather guard. The adjusting device is mounted on a bottom side of the workbench, and the adjusting device is mounted on a bottom side of the workbench to adjust the position of the leather guard. The adjusting device is mounted on a bottom side of the workbench, and the adjusting device is mounted on a bottom side of the workbench to adjust the position of the leather guard. The adjusting device is mounted on a bottom side of the workbench

[0007] By adopting the above technical solution, firstly, it can not only realize the cutting of leather, but also has multiple functions such as blocking, adjusting, and collecting the cut leather, thereby improving the cutting efficiency and cutting quality and reducing the tediousness of manual operation; secondly, by adjusting the position of the blocking plate through the adjustment component, the leather can be accurately positioned to avoid the displacement of the leather during the cutting process, thereby improving the cutting accuracy; thirdly, after the cutting is completed, the rotating plate rotates, and the cut leather slides into the collection box from the open groove, which is convenient for its unified collection and sorting, thereby reducing the steps of personnel sorting the leather and facilitating subsequent processing and transportation.

[0008] Optionally, the reset assembly includes multiple sliding rods and multiple reset springs, the lower ends of the multiple sliding rods are fixedly connected to the upper end of the connecting frame, the multiple sliding rods are respectively passed through the two ends of the workbench and the upper ends are fixedly connected to the two ends of the crossbeam, the multiple reset springs are respectively sleeved on the outside of the sliding rods, the two ends of the multiple reset springs are respectively fixedly connected to the upper side of the connecting frame and the lower side of the workbench, the outsides of the multiple sliding rods are respectively connected to positioning blocks, and both ends of the workbench are provided with slots for inserting positioning blocks.

[0009] By adopting the above technical solution, when the position of the beam needs to be adjusted, the slide rod can slide along the workbench so that the beam can be smoothly moved to the required position. After the adjustment, with the help of the elastic force of the reset spring, the electric connecting frame, the slide rod and the beam return to their original positions, which not only ensures the stability of the beam during the cutting process, but also facilitates the adjustment of the position of the beam according to the size of the leather and the cutting requirements. Through the cooperation of the positioning block, the workbench and the slide rod, the beam can be prevented from being displaced during the cutting process, thereby ensuring the stability and accuracy of the cutting process.

[0010] Optionally, the limit member includes a limit plate, multiple positioning rods and multiple thrust springs. One side of the positioning box is provided with multiple limit openings for the installation of the limit plate. The two ends of the limit plate are rotatably connected to the inner walls on the opposite sides of the limit opening. One end of each of the limit plates is respectively provided with a positioning hole for multiple positioning rods to pass through. A hinge block is connected between one end of each positioning rod and the side wall of the positioning box. Both ends of each positioning rod are fixedly connected to the limit plate. The two ends of each thrust spring are respectively abutted between one of the limit plates and the limit plate, and are sleeved on the outside of the positioning rod. The end of the limit plate facing away from the positioning hole abuts against the lower side of the rotating plate.

[0011] By adopting the above technical solution, through the cooperation of the thrust spring, the positioning rod and the limit plate, when the device is not in use, the elastic force of the thrust spring pushes one end of the limit plate to lift up, so that the positioning hole slides along the positioning rod, and the positioning rod rotates along the hinge block, preventing jamming between the positioning rod and the limit plate. At this time, the other end of the limit plate is lowered, so that the rotating plate can rotate in the open slot, so that the open slot is in a normally open state.

[0012] Optionally, each of the limit plates is hinged to a connecting rod at one end near the positioning hole, and the other end of each connecting rod is hinged to a positioning seat fixedly connected to the upper side of the connecting frame. The lower end of the connecting frame is fixedly connected to a pedal. When the pedal is stepped on, the connecting frame is at the lowest point. At this time, the connecting rod pulls the limit plate to rotate.

[0013] By adopting the above technical solution, the operator can move the connecting frame downward by stepping on the pedal, and the connecting rod pulls one end of the limit plate to rotate. At this time, the limit plate abuts against the lower side of the rotating plate, so that the open groove is closed, preventing the cutting end from bending when cutting leather.

[0014] Optionally, the inner walls on both sides of the opposite sides of the slide are fixedly connected to fixed rods, and sliding grooves for the sliding of the fixed rods are provided on both sides of the beam. Both ends of the beam are fixedly connected to blocking members for limiting the sliding range of the slide, and the lower end of the beam is fixedly connected to a limiting edge strip connected to the lower side of the slide.

[0015] By adopting the above technical solution, the slide can be ensured to move in a straight line, avoiding the slide from deflecting or shaking during the sliding process; at the same time, the blocking parts at both ends of the beam can limit the sliding range of the slide, preventing the slide from sliding out of the beam, and ensuring that the slide always moves within a safe range; the limiting edge strips can provide certain support and limiting effects on the slide, preventing the slide from colliding with the leather during the sliding process, thereby ensuring the accuracy of leather cutting.

[0016] Optionally, an anti-slip pad is fixedly connected to the upper side of the slide, a plurality of rollers that rotate with the upper side of the beam are rotatably connected to the inner side of the slide, and a fixing component for limiting the position of the cutter is installed on one side of the slide.

[0017] By adopting the above technical solution, the anti-slip pad can increase the friction between the slide and the operator's hand, reduce the slide from slipping during operation, and the roller can make the slide smoother during sliding, reduce the friction resistance between the slide and the beam, reduce the physical exertion of the staff, and thus improve the cutting efficiency; the cutter is firmly fixed to the slide through the clamping plate and fasteners to ensure that the cutter is always in the correct position, thereby ensuring the cutting accuracy and quality, and facilitating the installation and disassembly of the cutter, which is convenient for equipment maintenance and replacement of the cutter.

[0018] Optionally, the fixing assembly includes a card plate and multiple fasteners, a card slot for inserting the card plate is opened on one side of the slide seat, multiple fasteners are threadedly connected to the four corners of the card plate and one end is threadedly connected to the inner wall of the card slot, and a groove for inserting the cutter is opened on one side of the card plate.

[0019] By adopting the above technical solution, the cutter can be firmly fixed in the groove of the card plate. The threaded connection method of the fastener makes the fixation of the cutter more firm and reliable, and can withstand a large cutting force, thereby preventing the cutter from loosening or falling off during the cutting process. By adjusting the tightness of the fastener, the position of the cutter can be easily fine-tuned to meet the cutting requirements of leather of different thicknesses, and it is also convenient for maintenance and replacement of parts.

[0020] Optionally, the clamping plate is threadedly connected to a knob, one end of the knob is rotatably connected to a splint, a movable groove for sliding the splint is provided on the inner side of the groove, and a gasket is fixedly connected to the side of the splint close to the cutter.

[0021] By adopting the above technical solution, by turning the knob, the splint slides in the movable groove, so that the cutter can be pressed tightly between the clamping plate and the slide seat, which can further prevent the cutter from loosening or shaking during the cutting process. The operation is simple and convenient; and the gasket can protect the cutter, preventing the splint from directly contacting the cutter and causing damage to the cutter, thereby extending the service life of the cutter.

[0022] Optionally, a knife groove for the lower end of the cutter to be inserted and slid is provided on the upper side of the workbench and the upper side of the rotating plate.

[0023] By adopting the above technical solution, the knife groove can provide a stable sliding space for the lower end of the cutter, ensuring that the cutter can slide smoothly during the cutting process, and can avoid the cutter from colliding or getting stuck with the workbench or rotating plate, so that the leather can be completely cut, thereby ensuring cutting accuracy and straightness, and improving cutting quality.

[0024] Optionally, the adjusting assembly includes a threaded rod and multiple connecting blocks, the upper sides of the multiple connecting blocks are fixedly connected to the lower side of the baffle plate, the workbench is provided with multiple limit slots for inserting the connecting blocks, the two ends of the threaded rod are rotatably connected to the inner walls on both sides of the middle limit slot, and the outer wall is threadedly connected to the inner wall of the connecting block, the end of the threaded rod extending out of the workbench is fixedly connected to a crank, the inner wall fixing rods of the limit slots at both ends are connected to the limit rods passing through the inner wall of the connecting block, and the baffle plate is provided with a slot for inserting leather on the side close to the opening slot.

[0025] By adopting the above technical solution, the rotation of the threaded rod drives the connecting block to move along the limiting groove, thereby changing the position of the material blocking plate to accommodate leathers of different sizes. At the same time, the setting of the limiting groove and limiting rod can limit the connecting block to prevent it from shifting or shaking during movement. After one end of the leather is inserted into the notch, the cut end of the leather can be prevented from bending during placement, thereby improving cutting accuracy.

The lower end of the reset component 6 is fixedly connected to a connecting frame 5, and the lower end of the connecting frame 5 is fixedly connected to a pedal 51. When the pedal 51 is stepped on, the connecting frame 5 can be driven to move, thereby driving the reset component 6 and the crossbeam 2 to move. A slide 3 is slidably mounted on the outer side of the crossbeam 2, and a cutter 4 for cutting leather is mounted on one side of the slide 3. An adjustment component 8 is fixedly mounted on the upper side of the workbench 1, and a baffle plate 7 is fixedly connected to the upper end of the adjustment component 8. The baffle plate 7 is used to block the leather to ensure the accuracy of leather cutting. The adjustment component 8 is used to quickly adjust the position of the baffle plate 7, so that the cutting size of the leather can be quickly adjusted.

[0033] When in use, first, spread the leather flat on the workbench 1, and then operate the adjustment component 8 to adjust the position of the baffle plate 7 according to the cutting size of the leather; then, move the leather until one side of it abuts against the baffle plate 7; then, step on the pedal 51 to drive the connecting frame 5, the reset component 6 and the beam 2 to move downward until the beam 2 is pressed against the upper side of the leather to complete the positioning of the leather; then, push the slide 3 to slide along the beam 2, at this time, the cutter 4 will pass through the leather to complete the cutting of the leather; finally, release the pedal 51, and use the reset component 6 to drive the connecting frame 5 and the beam 2 back to their original position. At this time, remove the cut leather and repeat the above steps to complete the cutting of the leather.

[0034] Reference Figure 1 、 Figure 2 An open slot 10 is provided on the side of the workbench 1 close to the baffle plate 7, and a rotating plate 11 is hinged on the inner side of the open slot 10. The rotation of the rotating plate 11 can complete the covering and opening of the open slot 10, so that the cut leather can slide through the open slot 10. A positioning box 9 is fixedly connected to the lower side of the workbench 1, and the upper end of the positioning box 9 is in communication with the open slot 10. A collection box 91 is slidably provided on the inner wall of the positioning box 9. When the leather slides into the open slot 10 along the rotating plate 11, it can fall into the collection box 91, which is convenient for uniformly collecting and sorting the cut leather. A slot 71 for inserting leather is provided on the side of the baffle plate 7 close to the open slot 10. The connection between the slot 71 and the leather is used to prevent the leather from bending when the open slot 10 is opened, thereby ensuring the cutting quality of the leather.

[0035] Reference Figure 1 、 Figure 2 and Figure 4 The adjustment assembly 8 includes a threaded rod 81 connected to the workbench 1 and a plurality of connecting blocks 82 fixedly connected to the lower side of the material retaining plate 7. The upper side of the workbench 1 is provided with a plurality of limit slots 15 for the sliding movement of the plurality of connecting blocks 82. The limit slots 15 are used to limit the sliding range of the connecting blocks 82 and ensure the smoothness of the sliding. The two ends of the threaded rod 81 are rotatably connected to the inner walls on the opposite sides of the middle limit slot 15, and the outer wall is threadedly connected to the inner wall of the middle connecting block 82. The end of the threaded rod 81 extending from the workbench 1 is fixedly connected to a crank 811. Turning the crank 811 can drive the threaded rod 81 to rotate, thereby driving the connecting blocks 82 to move in the limit slot 15, and then driving the material retaining plate 7 to slide on the upper side of the workbench 1. The inner walls of the connecting blocks 82 at both ends are pierced with limiting rods 83, and the two ends of each limiting rod 83 are fixedly connected to the inner walls of the limiting grooves 15 at both ends. The connecting blocks 82 slide in the limiting grooves 15 along the limiting rods 83 to prevent them from being misplaced during movement.

[0036] Reference Figure 2 、 Figure 3 and Figure 4The inner walls of the slide 3 are fixedly connected to fixed rods 31 on opposite sides. Slots 21 are provided on both sides of the crossbeam 2 for the sliding movement of the fixed rods 31. The sliding movement of the fixed rods 31 within the slots 21 prevents the slide 3 from becoming dislocated or detaching from the crossbeam 2 during movement. Both ends of the crossbeam 2 are fixedly connected to stoppers 22, which limit the sliding range of the slide 3. In this application, the stoppers 22 are bolts. In other embodiments, the stoppers 22 can also be steel nails, metal blocks, or other materials. The lower end of the crossbeam 2 is fixedly connected to a limiting edge strip 23 connected to the underside of the slide 3. The limiting plates 121 prevent the slide 3 from contacting the leather during sliding, thereby further ensuring the stability of the slide 3. The inner side of the slide 3 is rotatably connected to two rollers 33 that rotate with the upper side of the crossbeam 2. The sliding of the rollers 33 on the crossbeam 2 improves the sliding efficiency of the slide 3 and reduces physical exertion. An anti-skid pad 32 is fixedly connected to the upper side of the slide 3 , and the anti-skid pad 32 is used to prevent an operator from slipping when gripping the slide 3 to slide.

[0037] Reference Figure 2 、 Figure 3 and Figure 4 The limiting assembly includes a slide rod 61 fixedly connected to the upper end of the connecting frame 5, a positioning block 63 slidably mounted on the outside of the slide rod 61, and a return spring 62 fixedly connected and sleeved on the outside of the slide rod 61. Slots 13 for the positioning blocks 63 are provided at both ends of the workbench 1. The slide rod 61 passes through the underside of the workbench 1 and is slidably connected to the inner wall of the positioning block 63. The positioning block 63 is used to ensure the stable sliding of the slide rod 61 and reduce friction between the slide rod 61 and the workbench 1. The return spring 62 is fixedly connected between the connecting frame 5 and the underside of the workbench 1. The elastic force of the return spring 62 is used to keep the connecting frame 5 in its original position at all times, ensuring the stability of the structure.

[0038] When the pedal 51 is stepped on to drive the connecting frame 5 to move downward, the slide rod 61 will slide on the inner wall of the positioning block 63. At this time, the return spring 62 will extend until it drives the beam 2 to contact the leather and press the leather. When the pedal 51 is released, the return spring 62 will contract, driving the connecting frame 5, the slide rod 61 and the beam 2 back to their original positions, completing the automatic reset of the structure.

[0039] Reference Figure 4 、 Figure 5 and Figure 6The upper end of the positioning box 9 is provided with a plurality of limiting openings 92, and a limiting member 12 is installed on the inner side of each limiting opening 92. The limiting member 12 is used to limit the opening and closing of the rotating plate 11. The limiting member 12 includes a limiting plate 121 rotatably installed on the inner wall of the limiting opening 92. One end of the limiting plate 121 abuts against the lower side of the rotating plate 11 and is used to drive the rotating plate 11 to rotate. Two positioning holes 124 are provided at the other end of the limiting plate 121. A positioning rod 122 is pierced through the inner wall of each positioning hole 124. The positioning rod 122 can move on the inner wall of the positioning hole 124 as the limiting plate 121 rotates. Both ends of the positioning rod 122 are fixedly connected to a limiting plate 1221. The limiting plate 1221 is used to prevent the positioning rod 122 from disengaging from the positioning hole 124. A thrust spring 123 is fixedly connected between one side of one of the limiting plates 1221 and the underside of the limiting plate 121. The thrust spring 123 is sleeved around the outside of the positioning rod 122 to prevent the thrust spring 123 from bending or deforming during extension or contraction. A hinge block 125 is fixedly connected between one end of the positioning rod 122 and the positioning box 9. The hinge block 125 positions the positioning rod 122 and enables it to rotate accordingly with the rotation of the limiting plate 121.

[0040] When the end of the limiting plate 121 close to the positioning hole 124 is pulled to rotate downward, the thrust spring 123 will be pressed to contract. At this time, one end of the positioning rod 122 will move in the positioning hole 124, and the other end of the positioning rod 122 will rotate along the hinge block 125 until the other end of the limiting plate 121 pushes the rotating plate 11 to abut against the inner side of the opening slot 10, completing the closure of the opening slot 10; when the limiting plate 121 is released, the elastic force extended by the thrust spring 123 pushes one end of the limiting plate 121 to rise and the other end to fall. At this time, the rotating plate 11 can rotate in the opening slot 10, so that the opening slot 10 is in an open state.

[0041] Reference Figure 4 、 Figure 5 and Figure 6 One end of each limiting plate 121 is hinged to a connecting rod 126, and the other end of each connecting rod 126 is hinged to a positioning seat 127, and each positioning seat 127 is fixedly installed on the upper side of the connecting frame 5, and the connecting rod 126 is rotatably installed between the limiting plate 121 and the positioning seat 127, so that when the connecting frame 5 moves, it can drive one end of the limiting plate 121 to rotate through the positioning seat 127 and the connecting rod 126, so that the limiting member 12 and the reset assembly 6 can operate synchronously.

[0042] Reference Figure 7A fixing assembly 34 for locking the cutter 4 is mounted on one side of the slide 3. The fixing assembly 34 includes a clamping plate 341 and fasteners 342 threadedly connected to the four corners of the clamping plate 341. A slot 35 is defined on one side of the slide 3 for inserting the clamping plate 341. The slot 35 is used to accurately position the clamping plate 341. One end of each fastener 342 is threadedly connected to the inner wall of the slot 35, securing the clamping plate 341 within the slot 35. A groove 343 is defined on one side of the clamping plate 341 for inserting the cutter 4, preventing the cutter 4 from misaligning between the clamping plate 341 and the slot 35. A movable slot 344 is defined within the recess 343. A clamping plate 346 is slidably connected to the inside of the movable slot 344. A knob 345, threadedly connected to the clamping plate 341, is rotatably connected to one side of the clamping plate 346. Rotating the knob 345 drives the clamping plate 346 to move within the movable slot 344, thereby clamping the cutter 4. A gasket 347 is fixedly connected to the side of the clamping plate 346 near the cutter 4. The gasket 347 increases friction between the clamping plate 346 and the cutter 4, preventing the cutter 4 from sliding or misaligning during use.

[0043] When in use, first, install the cutter 4 into the inner side of the groove 343, then move the clamping plate 341 to fit the inner wall of the clamping groove 35. At this time, use a tool to rotate the fastener 342 through the clamping plate 341 and into the inner wall of the clamping groove 35 to complete the installation of the clamping plate 341; then, rotate the knob 345 to drive the clamping plate 341 and the gasket 347 to move in the movable groove 344 until one side of the gasket 347 abuts against the outer side of the cutter 4, so that the cutter 4 is fixed between the knife groove 14 and the inner wall of the clamping groove 35.

[0044] When it is necessary to adjust the extended length of the cutter 4, first, control the crossbeam 2 to press the leather of corresponding size; then, loosen the knob 345 to release the lock of the cutter 4. At this time, the cutter 4 will naturally slide down until the lower end of the cutter 4 contacts the bottom wall of the knife groove 14 on the workbench 1, and then tighten the knob 345 to lock the cutter 4 again, completing the adjustment of the position of the cutter 4.

[0045] The implementation principle of the simple leather cutting machine in the embodiment of the present application is: When cutting leather, the first step is to lay the leather flat on the workbench 1. According to the size of the leather to be cut, the crank 811 is turned to drive the threaded rod 81 to rotate, and the connecting block 82 and the baffle plate 7 are moved to the specified position; then, the leather is pulled through the lower side of the crossbeam 2 and one end of it is inserted into the notch 71 on one side of the baffle plate 7, completing the work of straightening the plate before cutting the leather; In the second step, the pedal 51 is stepped on to move the connecting frame 5 downward. At this time, the return spring 62 extends, and the slide bar 61 slides vertically along the positioning block 63 at both ends of the workbench 1 until the lower side of the crossbeam 2 is pressed tightly against the upper side of the leather, completing the fixation of the leather position; and during the movement of the connecting frame 5, the connecting rod 126 is driven by the positioning seat 127 to pull one end of the limit plate 121 to rotate. At this time, the thrust spring 123 contracts, and the other end of the limit plate 121 presses against the rotating plate 11 and presses against the inner wall of the opening groove 10, so that the opening groove 10 is in a closed state; In the third step, the slide 3 is pushed to slide along the outer wall of the crossbeam 2, driving the fixed rod 31 to slide inside the slide groove 21 and the roller 33 to rotate on the upper side of the crossbeam 2, thereby driving the cutter 4 to slide in the knife groove 14 until the cutter 4 completely cuts through the leather and the slide 3 contacts one of the stoppers 22, completing the cutting of the leather. In the fourth step, the pedal 51 is released, and the return spring 62 is used to return and contract the connecting frame 5 and the sliding rod 61 to move upward until the crossbeam 2 is brought back to its original position, completing the restoration of the crossbeam 2. In the process of the connecting frame 5 moving upward, the connecting rod 126 releases the traction on the limit plate 121. At this time, the thrust spring 123 extends, pushing one end of the limit plate 121 to rotate and lift along the positioning rod 122, so that the other end of the limit plate 121 descends, releasing the lock on the rotating plate 11, so that the opening groove 10 is in an open state, and the cut leather is gently pushed to slide along the upper side of the rotating plate 11 from the opening groove 10 into the collection box 91, completing the collection of the cut leather. Step 5: Repeat the above operation to repeatedly complete the cutting of the leather. After cutting a certain amount of leather, the collection box 91 is pulled out from the positioning box 9. After the leather is taken out, the collection box 91 is inserted into the positioning box 9 again to collect the cut leather again.

[0046] When the size of the leather changes, leather of corresponding thickness is placed on the lower side of the beam 2, and then the pedal 51 is stepped on to drive the beam 2 to press the leather; then, the knob 345 is loosened, so that the gasket 347 on one side of the clamping plate 346 is separated from the cutter 4. At this time, the cutter 4 naturally falls with the help of its own gravity until the lower end of the cutter 4 contacts the bottom of the knife groove 14; then, the knob 345 is tightened until the gasket 347 on one side of the clamping plate 346 is pressed against one side of the cutter 4, fixing the cutter 4 between the clamping plate 341 and the clamping groove 35, and completing the adjustment of the position of the cutter 4.
