Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive seat processing technology, and in particular to a device for cutting leather for automotive seat cushions. Background Technology
[0002] Car seats are seats used when riding in a car. They are usually made of leather and foam covering the frame. Leather is a key component of the seat, and cutting equipment is usually needed to cut the leather during the production process.
[0003] Existing car seat cushion leather cutting devices typically place the leather directly on a flat surface for cutting. When the leather wrinkles, the cut leather shape deviates, making it impossible to accurately cut the desired shape and reducing the processing quality. Summary of the Invention
[0004] In view of this, the present invention provides a leather cutting device for car seat cushions. The main technical problem to be solved is that the leather cannot be accurately cut into the required shape due to wrinkles during leather cutting.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a leather cutting device for car seat cushions, comprising a frame, a cutting device fixedly connected to the upper part of the frame, fixed cylinders fixedly connected to the front and rear sides of the lower part of the cutting device, a movable shell fixedly connected to the lower part of the fixed cylinder, a pull plate movably connected to the lower part of the movable shell, a leather winding cylinder fixedly connected to the front side of the frame, the fixed cylinder comprising a cylinder body fixedly connected to the front and rear sides of the lower part of the cutting device, an inclined block fixedly connected to the inside of the cylinder body, a first sliding column fixedly connected to the inner side of the inclined block, a first slider movably connected to the outer side of the first sliding column, and a first spring fixedly connected between the inclined block and the first slider.
[0006] By adopting the above technical solution, the bottom of the inclined block is inclined, and the angle of inclination of the first sliding column is the same as the angle of inclination of the bottom of the inclined block, so that the first slider can move upward to both sides of the cutter when it is squeezed. The first spring is used to squeeze the first slider so that the first slider can be stably located on the right side outside the first sliding column, and when the first slider moves due to external force and can return to its original position after the external force is removed.
[0007] As a further description of the above technical solution: the frame includes a cutting plate, the lower part of which is fixedly connected to a support column, and the top of which is fixedly connected to a frame.
[0008] By adopting the above technical solution, the cutting board is used for placing the leather, and the frame is used to fix and support the cutting device.
[0009] As a further description of the above technical solution: the cutting device includes a hydraulic telescopic rod fixedly connected inside the frame body, a fixed plate fixedly connected to the bottom end of the hydraulic telescopic rod, a cutter fixedly connected to the lower part of the fixed plate, and limit rods fixedly connected to both sides of the top of the fixed plate, the limit rods being movably connected to the frame body.
[0010] By adopting the above technical solution, the hydraulic telescopic rod is activated to drive the fixed plate down, which in turn causes the cutter to descend. By continuously descending, the cutter comes into contact with the leather and cuts it under pressure.
[0011] As a further description of the above technical solution: the movable shell includes a connecting post fixedly connected to the lower part of the first slider, the bottom end of the connecting post is fixedly connected to the shell, the inner side of the shell is fixedly connected to a second sliding post, and the rear side of the inner side of the shell is fixedly connected to a second spring.
[0012] By adopting the above technical solution, the second spring is used to compress the second slider.
[0013] As a further description of the above technical solution: the pull plate includes a second slider movably connected to the outside of the second slide column, a plate body is fixedly connected to the lower part of the second slider, an anti-slip pad is fixedly connected to the lower part of the plate body, and the second slider is fixedly connected to the second spring.
[0014] By adopting the above technical solution, the hydraulic telescopic rod is controlled to lower the fixed plate. Since the bottom of the pull plate is lower than the bottom of the cutter, the anti-slip pad contacts the leather first as the plate descends. The anti-slip pad has a certain anti-slip effect and will not easily move when it contacts the leather. Furthermore, the continuous descent causes the connecting column to press against the first slider, which in turn causes the slider to move inside the inclined block. This movement causes the moving shell to move upwards and away from the sides of the cutter relative to the fixed cylinder, ultimately raising the position of the pull plate relative to the cutter. This allows the lower part of the cutter to contact the leather and cut it through compression. Simultaneously, as the moving shell moves away from the sides of the cutter, it compresses the second spring. During compression, there is a certain distance between the left side of the second slider and the shell. Under the compression of the second spring, the second slider generates a force on both sides of the cutter, which in turn generates a force on both sides of the plate and the anti-slip pad. This allows the leather in contact with the anti-slip pad to be flattened by the force generated by the anti-slip pad, ensuring that no wrinkles appear at the cutting position and accurately cutting out the leather of the desired shape.
[0015] As a further description of the above technical solution: the leather take-up drum includes a connecting block fixedly connected to the front side of the cutting board, the connecting block is internally threaded with bolts, a fixed shaft is placed between the bolts, and the take-up drum body is movably connected to the outside of the fixed shaft.
[0016] By adopting the above technical solution, both sides of the fixed shaft are provided with grooves that are compatible with the bolts, and the sum of the depth of the groove and the thickness of the connecting block is less than the thread length on the bolt, so that the bolt can be pressed into the grooves on both sides of the fixed shaft, which is convenient for fixing and can be disassembled. When the leather on the leather winding drum is used up, a new leather winding drum can be replaced.
[0017] As a further description of the above technical solution: the upper front side of the cutting board is rounded.
[0018] By adopting the above technical solution, it is guaranteed that it will not scratch the leather.
[0019] As a further description of the above technical solution: the anti-slip mat is made of rubber.
[0020] By adopting the above technical solution, its anti-slip effect is better, ensuring that it will not easily move when in contact with leather, thereby ensuring that the force exerted by the pull plate on the leather to both sides is more stable, so that the wrinkles on the leather can be smoothed out better.
[0021] By employing the above technical solution, the automotive seat cushion leather cutting device of this utility model has at least the following beneficial effects:
[0022] Compared with existing technologies, this automotive seat cushion leather cutting device, with its fixed cylinder, movable shell, and pull plate, facilitates the smoothing of wrinkles on the leather. By controlling the hydraulic telescopic rod, the fixed plate is lowered. Since the bottom of the pull plate is lower than the bottom of the cutter, the continuous descent allows the anti-slip pad to contact the leather first. The anti-slip pad provides a certain degree of slip resistance and will not easily move when in contact with the leather. Furthermore, the continuous descent causes the connecting column to press against the first slider, which in turn moves the slider below the inside of the inclined block. This movement causes the movable shell to continuously move upwards and away from the sides of the cutter relative to the fixed cylinder. The movement causes the pull plate to rise relative to the cutter, allowing the lower part of the cutter to contact the leather and cut it through compression. Simultaneously, as the moving housing moves away from the sides of the cutter, it compresses the second spring. During compression, there is a certain distance between the left side of the second slider and the housing. Under the compression of the second spring, the second slider generates a force on both sides of the cutter, which in turn generates a force on both sides of the plate and the anti-slip pad. This allows the leather in contact with the anti-slip pad to be flattened by the force generated by the anti-slip pad, ensuring that no wrinkles appear at the cutting point and accurately cutting out the desired shape of leather.

[0029] Reference Figure 1-4 This utility model provides a leather cutting device for car seat cushions, including a frame 1. A cutting device 2 is fixedly connected to the upper part of the frame 1. Fixed cylinders 3 are fixedly connected to the front and rear sides of the lower part of the cutting device 2. A movable shell 4 is fixedly connected to the lower part of the fixed cylinder 3. A pull plate 5 is movably connected to the lower part of the movable shell 4. A leather winding cylinder 6 is fixedly connected to the front side of the frame 1. The leather winding cylinder 6 is used to wind and place the leather. The fixed cylinder 3 includes a cylinder body 301 fixedly connected to the front and rear sides of the lower part of the cutting device 2. An inclined block 302 is fixedly connected to the inside of the cylinder body 301. A first sliding column 3 is fixedly connected to the inner side of the inclined block 302. 03. The bottom of the inclined block 302 is inclined. The angle of inclination of the first sliding column 303 is the same as the angle of inclination of the bottom of the inclined block 302. The first slider 305 is movably connected to the outside of the first sliding column 303. The first slider 305 can move between the outside of the first sliding column 303 and the inside of the inclined block 302. A first spring 304 is fixedly connected between the inclined block 302 and the first slider 305. The first spring 304 is used to squeeze the first slider 305 so that the first slider 305 can be stably located on the right side outside the first sliding column 303. When the first slider 305 moves due to external force, it can return to its original position after the external force is removed.
[0030] Furthermore, the frame 1 includes a cutting plate 101 for placing leather. A support column 102 is fixedly connected to the lower part of the cutting plate 101, and a frame 103 is fixedly connected to the top of the cutting plate 101 for fixing and supporting the cutting device 2.
[0031] Furthermore, the cutting device 2 includes a hydraulic telescopic rod 201 fixedly connected inside the frame 103. A fixed plate 203 is fixedly connected to the bottom end of the hydraulic telescopic rod 201. A cutter 204 is fixedly connected to the lower part of the fixed plate 203. Limiting rods 202 are fixedly connected to both sides of the top of the fixed plate 203. The limiting rods 202 are used to ensure that the movement of the cutter 204 is more stable. The limiting rods 202 are movably connected to the frame 103. By activating the hydraulic telescopic rod 201, it can drive the fixed plate 203 to descend, thereby causing the cutter 204 to descend. By continuously descending, it can contact the leather and cut the leather under pressure.
[0032] Furthermore, the movable shell 4 includes a connecting post 401 fixedly connected to the lower part of the first slider 305. The bottom end of the connecting post 401 is fixedly connected to a shell 404. The inner side of the shell 404 is fixedly connected to a second sliding post 402, which is used for the movement of the second slider 501. The rear side of the inner side of the shell 404 is fixedly connected to a second spring 403, which is used to compress the second slider 501.
[0033] Furthermore, the pull plate 5 includes a second slider 501 movably connected to the outside of the second sliding column 402. A plate 502 is fixedly connected to the lower part of the second slider 501, and an anti-slip pad 503 is fixedly connected to the lower part of the plate 502. The second slider 501 is fixedly connected to the second spring 403. In use, the hydraulic telescopic rod 201 is controlled to lower the fixed plate 203. Since the bottom of the pull plate 5 is lower than the bottom of the cutter 204, the anti-slip pad 503 contacts the leather first through continuous descent. The anti-slip pad 503 has a certain anti-slip effect and will not easily move when it contacts the leather. Furthermore, the continuous descent allows the connecting column 401 to press against the first slider 305. This pressing causes the first slider 305 to move inside the inclined block 302, and this movement causes the position of the moving shell 4 relative to the fixed cylinder 3 to continuously rise and fall. The sliding shell 4 moves away from the sides of the cutter 204, causing the pull plate 5 to rise relative to the cutter 204. This allows the lower part of the cutter 204 to contact the leather and cut it by squeezing. Simultaneously, as the sliding shell 4 moves away from the sides of the cutter 204, it squeezes the second spring 403. During this squeezing, there is a certain distance between the left side of the second slider 501 and the shell 404. Under the squeezing of the second spring 403, the second slider 501 generates a force on both sides of the cutter 204. This, in turn, causes the plate 502 and the anti-slip pad 503 to generate a force on both sides of the cutter 204. This allows the leather in contact with the anti-slip pad 503 to be flattened by the force generated by the anti-slip pad 503, ensuring that no wrinkles appear at the cutting position of the cutter 204 and accurately cutting out the leather of the desired shape.
[0034] Furthermore, the leather winding drum 6 includes a connecting block 601 fixedly connected to the front side of the cutting plate 101. The connecting block 601 is internally threaded with bolts 602, and a fixing shaft 603 is placed between the bolts 602. Both sides of the fixing shaft 603 are provided with slots that are adapted to the bolts 602, and the sum of the depth of the slot and the thickness of the connecting block 601 is less than the thread length on the bolt 602, ensuring that the bolts 602 can be pressed against the slots on both sides of the fixing shaft 603, which facilitates fixing and disassembly. When the leather on the leather winding drum 6 is used up, a new leather winding drum 6 can be replaced. The outer side of the fixing shaft 603 is movably connected to the winding drum body 604, which can rotate on the outer side of the fixing shaft 603, making it easy to pull out the leather.
[0035] Furthermore, the upper front of the cutting board 101 is rounded to ensure that it will not scratch the leather.
[0036] Furthermore, the anti-slip mat 503 is made of rubber, which has a good anti-slip effect and ensures that it will not easily move when in contact with the leather. This ensures that the force exerted by the pull plate 5 on the leather to both sides is more stable, so that the wrinkles on the leather can be smoothed out better.
[0037] Working principle: During use, the leather on the leather winding drum 6 is placed on the cutting plate 101. By controlling the hydraulic telescopic rod 201, the fixed plate 203 is lowered. Since the bottom of the pull plate 5 is lower than the bottom of the cutter 204, the anti-slip pad 503 can contact the leather first through continuous descent. The anti-slip pad 503 has a certain anti-slip effect and will not easily move when it contacts the leather. The continuous descent also causes the connecting column 401 to squeeze the first slider 305. Through squeezing, the first slider 305 can move inside the inclined block 302. Through this movement, the moving shell 4 moves upward and away from the sides of the cutter 204 relative to the fixed cylinder 3. Through this movement, the pull plate 5 moves relative to the cutter 204. The position rises, allowing the lower part of the cutter 204 to contact the leather and cut it through compression. Simultaneously, as the moving housing 4 moves away from the sides of the cutter 204, the housing 404 can compress the second spring 403. During compression, there is a certain distance between the left side of the second slider 501 and the housing 404. Under the compression of the second spring 403, the second slider 501 can generate a force on both sides of the cutter 204, which in turn allows the plate 502 and the anti-slip pad 503 to generate a force on both sides of the cutter 204. This allows the leather in contact with the anti-slip pad 503 to be flattened under the force generated by the anti-slip pad 503, ensuring that no wrinkles appear at the cutting position of the cutter 204, and accurately cutting out the leather of the required shape.
[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
