TECHNICAL FIELD

[0001] The utility model relates to leather processing technical field, concretely is a multifunctional leather cutting machine. BACKGROUND

[0002] Leather is often used as automotive interior materials, and is animal skin that has been denatured and is not easy to rot through physical and chemical processes such as unhairing and tanning. Leather is made of natural protein fibers tightly woven in three-dimensional space, and has a special grain layer on its surface, with natural grain and gloss, and comfortable hand feeling. Currently, in the production and processing of leather, especially in the production of finished products, in order to better produce finished products and save leather, the leather is cut accordingly to achieve better use effect.

[0003] A leather cutting machine is disclosed in the patent with the announcement number CN220579316U, which relates to the field of leather processing technology, and includes a workbench. A door-shaped frame is slidably installed on the workbench, and a cutting head is installed on the door-shaped frame. A cavity is formed in the workbench, and a pair of pull wires is rotatably installed in the cavity. A pair of first sliding blocks is rotatably connected to each of the pair of pull wires. A first sliding opening is formed in the workbench, and the first sliding blocks are slidably installed in the first sliding opening. A moving plate is fixedly installed on each of the first sliding blocks. A pneumatic cylinder clamp is fixedly installed at the center of each moving plate. This effectively solves the technical problem of the lack of a leather fixing assembly in existing leather cutting machines, which makes it difficult to fix the leather during cutting, leading to easy movement of the leather and deviation of the cutting position.

[0004] However, the above-mentioned leather cutting machine cannot perform cutting and pressing operations simultaneously during the cutting process, and the leather needs to be refilled by the staff each time, which cannot be filled with multiple groups of leather at one time and cut in sequence, which increases the cutting time of each leather product and reduces the overall production efficiency. UTILITY MODEL CONTENTS

[0005] The utility model aims at providing a multifunctional leather cutting machine to solve the problem of the inability to simultaneously perform cutting and pressing operations during the cutting process of leather, and the need for staff to refill the leather each time during the cutting process, which cannot fill multiple groups of leather at one time and cut in sequence.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical scheme:

[0007] A multi-functional leather cutting machine includes: a support frame, two sets of baffles fixedly installed on the upper surface of the support frame, a bearing cylinder fixedly installed between the two sets of baffles, a conveyor belt driven between the two sets of baffles, a baffle provided inside the conveyor belt, the baffles fixedly installed between the two sets of baffles, two sets of linear modules fixedly installed on one side of each of the two sets of baffles, an mounting plate fixedly installed between the moving blocks of the four sets of linear modules, and a cutting mechanism fixedly installed on the lower surface of the mounting plate;

[0008] The mounting plate has a connecting cylinder fixedly installed on its upper surface, and a storage groove is provided on the lower surface of the connecting cylinder. The storage groove is connected to the lower surface of the mounting plate, and a pressing mechanism is slidably installed in the storage groove.

[0009] Preferably, the cutting mechanism includes a cross slide, which is fixedly installed on the lower surface of the mounting plate. A connecting plate is fixedly installed at one end of the moving block of the cross slide, a brake motor is fixedly installed on the lower surface of the connecting plate, and a cutting scissor column is fixedly installed on the lower surface of the output shaft of the brake motor.

[0010] Preferably, a sleeve is fixedly installed on the lower surface of the moving block of the cross slide, and the sleeve is fitted onto the outer surface of the brake motor.

[0011] Preferably, the pressing mechanism includes a slide bar, which is slidably installed in the receiving groove. A pressing rod is fixedly installed between the two sets of slide bars. The pressing rod protrudes 15-20cm longer than the cutting column, and the pressing rod is flush with and equal in width to the conveyor belt.

[0012] Preferably, a sliding column is fixedly installed inside the storage slot, and a spring is fitted on the outer surface of the sliding column. The two ends of the spring respectively contact the upper surface of the storage slot and the upper surface of the sliding column.

[0013] Preferably, when the top pressing rod is driven by the linear module to press against the leather surface on the upper surface of the conveyor belt, the top pressing rod will slide into the storage groove through the slide rod so that the cutting scissors can contact the leather on the upper surface of the conveyor belt for multi-directional cutting.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. Through the design of the conveyor belt, linear module, connecting cylinder, storage groove, pressing mechanism, and cutting mechanism, when cutting leather, the operator can place multiple sets of leather on the upper surface of the conveyor belt. As the conveyor belt moves, it sequentially transports the leather to directly below the mounting plate and then stops. Once the leather is under the mounting plate, the linear module is activated, causing the mounting plate between the moving blocks to move vertically downwards. The pressing mechanism, which is slidably installed in the storage groove of the connecting cylinder on the upper surface of the mounting plate, will initially contact the front and rear ends of the leather. As the mounting plate is continuously pressed down by the linear module, the pressing mechanism will continuously slide into the storage groove until the cutting mechanism contacts the surface of the leather and stops. The cutting mechanism then performs the cutting operation according to the programmed cutting path, thus achieving simultaneous cutting and pressing, saving time because it eliminates the need for separate... The process involves two steps. Performing both operations simultaneously ensures that the cut leather edges are smoother and neater, as the pressing immediately fixes the cut edges in the correct position. Most importantly, simultaneous cutting and pressing improves work efficiency and makes the entire cutting process smoother. After cutting, the linear module drives the mounting plate to reset, and the conveyor belt transports the cut leather out, then sequentially transports the next set of leather to be aligned with the mounting plate for the next cutting operation. This allows workers to lay out multiple sets of leather at once, eliminating the need to lay out leather again after each cutting operation. This improves work efficiency and the continuity of the production process. By laying out multiple sets of leather at once, multiple cutting operations can be performed continuously without having to spend time re-laying leather each time, saving a significant amount of time and increasing work efficiency.

[0016] 2. Through the design of the cross slide, brake motor, and cutting scissor column, when cutting leather, the operator can place multiple sets of leather on the upper surface of the conveyor belt. As the conveyor belt moves, it sequentially transports the leather to directly below the mounting plate, then stops. Once the leather is directly below the mounting plate, the linear module is activated, causing the mounting plate between the moving blocks to move vertically downwards. The top-pressing mechanism, slidably installed in the receiving groove of the connecting cylinder on the upper surface of the mounting plate, will preferentially contact the front and rear ends of the leather. As the mounting plate is continuously pressed down by the linear module, the top-pressing mechanism will continuously slide into the receiving groove until the cutting scissor column contacts the surface of the leather, at which point it stops. Then, the cross slide... The platform can cut the leather by driving the cutting scissor column at one end of the output shaft of the brake motor according to the cutting path set in the program. During the cutting process, the linear module will drive the mounting plate to lift up and pull the cutting scissor column out of the leather. Then, the brake motor will drive the cutting scissor column on the lower surface of the output shaft to change the cutting path. Subsequently, the linear module will drive the cutting scissor column to cut into the leather again for a second cutting operation. Each time the cutting scissor column is lifted, the top pressing mechanism will slide out of the storage slot for a certain length and always keep pressing on the surface of the leather. The cross slide table can ensure that the movement trajectory of the cutting scissor column is very accurate. Therefore, the cut leather is accurate in size and meets the design requirements.

[0017] 3. Through the design of the top pressure rod, spring, and slide rod, the conveyor belt stops when the leather is conveyed directly below the mounting plate. Then, the linear module is activated to drive the mounting plate between the moving blocks to move vertically downward. The slide rod, which is slidably installed in the storage groove of the connecting cylinder on the upper surface of the mounting plate, will first contact the front and rear ends of the leather through the top pressure rod. Subsequently, as the mounting plate is continuously driven and pressed down by the linear module, the top pressure rod will continuously slide into the storage groove through the slide rod and simultaneously contact one end of the spring in the storage groove. The spring will then apply a downward elastic force to the slide rod, which will cause the slide rod to drive the top pressure rod to press against the front and rear ends of the leather until the cutting scissors touch the surface of the leather, thus achieving the purpose of cutting and pressing simultaneously. Performing these two operations at the same time ensures that the edges of the cut leather are flatter and neater because pressing can immediately fix the cut edges in the correct position. Most importantly, performing cutting and pressing simultaneously can improve work efficiency and make the entire cutting process smoother. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-5 The present invention provides the following technical solution:

[0026] like Figures 1-3 As shown, a multi-functional leather cutting machine includes: a support frame 1, two sets of baffles 2 are fixedly installed on the upper surface of the support frame 1, a bearing cylinder 202 is fixedly installed between the two sets of baffles 2, a conveyor belt 201 is driven between the two sets of baffles 2, a baffle 2 is provided inside the conveyor belt 201, the baffles 2 are fixedly installed between the two sets of baffles 2, two sets of linear modules 3 are fixedly installed on one side of each of the two sets of baffles 2, an mounting plate 4 is fixedly installed between the moving blocks of the four sets of linear modules 3, and a cutting mechanism 6 is fixedly installed on the lower surface of the mounting plate 4;

[0027] The upper surface of the mounting plate 4 is fixedly mounted with a connecting cylinder 401, and the lower surface of the connecting cylinder 401 is provided with a storage groove 402. The storage groove 402 is connected to the lower surface of the mounting plate 4, and a top pressing mechanism 5 is slidably installed in the storage groove 402.

[0028] Through the design of the conveyor belt 201, linear module 3, connecting cylinder 401, storage groove 402, pressing mechanism 5, and cutting mechanism 6, when cutting leather, the operator can place multiple sets of leather on the upper surface of the conveyor belt 201. As the conveyor belt 201 is conveyed, it sequentially transports the leather to directly below the mounting plate 4 and then stops. Once the leather is directly below the mounting plate 4, the linear module 3 is activated, causing the mounting plate 4 between the moving blocks to move vertically downwards. The pressing mechanism 5, which is slidably installed in the storage groove 402 of the connecting cylinder 401 on the upper surface of the mounting plate 4, will preferentially contact the front and rear ends of the leather. As the mounting plate 4 is continuously pressed down by the linear module 3, the pressing mechanism 5 will continuously slide into the storage groove 402 until the cutting mechanism 6 contacts the surface of the leather and stops. The cutting mechanism 6 then performs the cutting operation according to the programmed cutting path, thus achieving simultaneous cutting and pressing. This saves time because the two steps don't need to be performed separately. Secondly, performing both operations simultaneously ensures that the edges of the cut leather are flatter and neater, as the pressing immediately fixes the cut edges in the correct position. Most importantly, simultaneous cutting and pressing improves work efficiency and makes the entire cutting process smoother. After cutting, the straight module 3 can drive the mounting plate 4 to reset and the conveyor belt 201 can transport the cut leather out, then transport the subsequent leathers to the mounting plate 4 to be aligned for the next cutting operation. This allows workers to lay out multiple sets of leather at once, eliminating the need to lay out the leather again each time during the cutting process, thus improving work efficiency and the continuity of the production process. By laying out multiple sets of leather at once, multiple cutting operations can be performed continuously without having to spend time re-laying the leather each time, which saves a lot of time and improves work efficiency.

[0029] like Figure 4 As shown, the cutting mechanism 6 includes a cross slide 601, which is fixedly installed on the lower surface of the mounting plate 4. A connecting plate 602 is fixedly installed on one end of the moving block of the cross slide 601. A brake motor 605 is fixedly installed on the lower surface of the connecting plate 602. A cutting scissor column 604 is fixedly installed on the lower surface of the output shaft of the brake motor 605.

[0030] A sleeve 603 is fixedly installed on the lower surface of the moving block of the cross slide table 601, and the sleeve 603 is fitted onto the outer surface of the brake motor 605.

[0031] Through the design of the cross slide 601, the brake motor 605, and the cutting shear column 604, when cutting leather, the operator can place multiple sets of leather on the upper surface of the conveyor belt 201. As the conveyor belt 201 is conveyed, it sequentially transports the leather to directly below the mounting plate 4 and then stops. Once the leather is directly below the mounting plate 4, the linear module 3 is activated, causing the mounting plate 4 between the moving blocks to move vertically downwards. The pressing mechanism 5, which is slidably installed in the receiving groove 402 of the connecting cylinder 401 on the upper surface of the mounting plate 4, will preferentially contact the front and rear ends of the leather. Subsequently, as the mounting plate 4 is continuously pressed down by the linear module 3, the pressing mechanism 5 will continuously slide into the receiving groove 402 until the cutting shear column 604 contacts the surface of the leather, at which point it stops. The slide table 601 can drive the cutting scissor column 604 at one end of the output shaft of the brake motor 605 to cut the leather according to the cutting path set in the program. During the cutting process, the linear module 3 will drive the mounting plate 4 to lift up and pull the cutting scissor column 604 out of the leather. Then, the brake motor 605 will drive the cutting scissor column 604 on the lower surface of the output shaft to change the cutting path. Subsequently, the linear module 3 will drive the cutting scissor column 604 to cut into the leather again for cutting. Each time the cutting scissor column 604 is lifted, the pressing mechanism 5 will slide out a certain length from the storage groove 402 and always keep pressing on the surface of the leather. The cross slide table 601 can ensure that the movement trajectory of the cutting scissor column 604 is very accurate. Therefore, the cut leather is accurate in size and meets the design requirements.

[0032] like Figure 5 As shown, the top pressing mechanism 5 includes a slide rod 504, which is slidably installed in the storage groove 402. A top pressing rod 501 is fixedly installed between the two sets of slide rods 504. The top pressing rod 501 protrudes 15-20cm longer than the cutting column 604. The top pressing rod 501 is flush with and equal in width to the conveyor belt 201.

[0033] A sliding column 503 is fixedly installed inside the storage slot 402. A spring 502 is fitted on the outer surface of the sliding column 503. The two ends of the spring 502 respectively contact the upper surface of the storage slot 402 and the upper surface of the sliding rod 504.

[0034] When the top pressure rod 501 is driven by the linear module 3 to press against the leather surface on the upper surface of the conveyor belt 201, the top pressure rod 501 will slide into the storage groove 402 through the slide rod 504 so that the cutting scissor column 604 can contact the leather on the upper surface of the conveyor belt 201 for multi-directional cutting.

[0035] Through the design of the top pressure rod 501, spring 502, and slide rod 504, when the leather is conveyed to the area directly below the mounting plate 4, the conveyor belt 201 stops conveying the leather. Then, the linear module 3 is activated to drive the mounting plate 4 between the moving blocks to move vertically downward. The slide rod 504, which is slidably installed in the storage groove 402 of the connecting cylinder 401 on the upper surface of the mounting plate 4, will first contact the front and rear ends of the leather through the top pressure rod 501. Subsequently, as the mounting plate 4 is continuously driven and pressed down by the linear module 3, the top pressure rod 501 will continuously slide into the storage groove 402 through the slide rod 504 and simultaneously contact the storage groove 402. One end of the spring 502 inside will apply a downward elastic force to the slide bar 504, which will cause the slide bar 504 to drive the top pressure bar 501 to press against the front and rear end surfaces of the leather until the cutting scissor column 604 touches the surface of the leather and stops. This achieves the purpose of cutting and pressing at the same time. Performing two operations at the same time can ensure that the edges of the cut leather are flatter and neater, because pressing can immediately fix the cut edges in the correct position. Most importantly, cutting and pressing at the same time can improve work efficiency and make the whole cutting process smoother.

[0036] Based on the above technical solution, the working steps of this solution are summarized as follows: When cutting leather, the worker can place multiple sets of leather on the upper surface of the conveyor belt 201. Then, as the conveyor belt 201 is conveyed, it can be sequentially conveyed to the area directly below the mounting plate 4, and then the conveyor belt 201 can be stopped. After the leather is conveyed to the area directly below the mounting plate 4, the linear module 3 can be activated to move the mounting plate 4 between the moving blocks vertically downward. The sliding rod 504, which is slidably installed in the storage groove 402 of the connecting cylinder 401 on the upper surface of the mounting plate 4, will preferentially push against the pressure rod 501 between them. The push rod 501 contacts the front and rear ends of the leather. As the mounting plate 4 is continuously pressed down by the linear module 3, the push rod 501 slides into the receiving groove 402 via the slide rod 504, simultaneously contacting one end of the spring 502 within the receiving groove 402. The spring 502 then applies a downward elastic force to the slide rod 504, causing the slide rod 504 to push the push rod 501 against the front and rear ends of the leather until the cutting scissor column 604 contacts the surface of the leather. Then, the cross slide 601 activates the brake according to the cutting path set in the program. The cutting scissor column 604 at one end of the output shaft of machine 605 performs a cutting operation on the leather. During the cutting process, the linear module 3 drives the mounting plate 4 to lift, pulling the cutting scissor column 604 out of the leather. Then, the brake motor 605 drives the cutting scissor column 604 on the lower surface of the output shaft to change the cutting path. Subsequently, the linear module 3 drives the cutting scissor column 604 to cut into the leather again for a second cutting operation. Each time the cutting scissor column 604 is lifted, the slide bar 504 slides out of the storage groove 402 for a certain length, ensuring that it always presses against the leather. On the surface, the cross slide 601 ensures that the movement trajectory of the cutting scissor column 604 is very accurate, so the cut leather is precisely sized. After cutting, the straight module 3 can drive the mounting plate 4 to reset and the conveyor belt 201 can transport the cut leather out, and then transport the leather that is placed next to it to be aligned with the mounting plate 4 for the next cutting operation. This allows workers to lay out multiple sets of leather at once, eliminating the need for workers to lay out the leather again during each cutting process, thereby improving work efficiency and the continuity of the production process.

[0037] In summary: This allows for simultaneous cutting and pressing operations, saving time as these two steps can be performed separately. Secondly, performing both operations simultaneously ensures smoother and neater edges on the cut leather, as pressing immediately fixes the cut edges in the correct position. Most importantly, simultaneous cutting and pressing improves work efficiency, making the entire cutting process smoother. It also allows workers to lay out multiple sets of leather at once, eliminating the need for workers to lay out the leather again after each cutting process, thus improving work efficiency and the continuity of the production process.
