Description

Technical Field

[0001] This utility model relates to the field of shoemaking equipment technology, and in particular to a breathable fabric cutting device for sports shoe production. Background Technology

[0002] Athletic shoes typically need to be highly breathable to ensure adequate ventilation for the feet during strenuous exercise, maintaining comfort during the activity. Common breathable fabrics used in athletic shoes have a multi-layered composite structure, including an outer high-density mesh layer, a middle functional breathable membrane, and an inner moisture-wicking fiber layer. Through unique weaving techniques and material combinations, the fabric significantly improves breathability and moisture-wicking performance while maintaining high-strength support, making it suitable for high-intensity sports activities.

[0003] Currently, breathable fabrics need to be cut according to specific production standards during production and processing. Because breathable fabrics are soft, the commonly used breathable fabric cutting device uses an external tensioning device to tension the fabric, so that the tensioned fabric can be cut successfully in one go.

[0004] However, when the tensioning device maintains tension on the composite breathable fabric and during the cutting process, the fabric is prone to flyaway threads and layer separation at the cut part, which affects the cutting quality of the fabric. Utility Model Content

[0005] In view of the above problems, this utility model provides a breathable fabric cutting device for sports shoe production.

[0006] To achieve the above-mentioned objectives, the technical solution adopted by this utility model is as follows:

[0007] A breathable fabric cutting device for sports shoe production is provided, characterized in that: it includes a support frame, a processing table is provided on the top of the support frame, an installation bracket is provided above the processing table, a cutting tool assembly for cutting the fabric is provided between the installation bracket and the processing table, and tensioning components for tensioning the fabric are provided on both sides of the cutting tool assembly on the installation bracket.

[0008] The tensioning assembly includes a lifting frame, and a first driving component is provided on the mounting bracket for driving the lifting frame to move vertically up and down. Two rotating rollers are arranged in parallel on the lifting frame. The two rotating rollers are located on both sides of the tool assembly. Both ends of the rotating rollers are unidirectionally connected to the lifting frame and rotate away from the tool assembly.

[0009] A friction roller is coaxially sleeved on the outer side of the rotating roller. The friction roller is used to contact the fabric. A limiting component is provided on the rotating roller to limit the rotation range of the friction roller relative to the rotating roller. A second driving component is provided on the lifting frame to drive the friction roller to rotate by friction. An elastic component is provided on the rotating roller to drive the friction roller to rotate in the direction of the cutter assembly.

[0010] Furthermore, the tool assembly includes a first tool and a second tool. The first tool is vertically slidably mounted on the mounting bracket. A mounting opening is provided on the machining table below the first tool. The second tool is located below the mounting opening and is vertically slidably mounted on the support frame. The support frame is provided with a third driving member for driving the first tool and the second tool to move synchronously in opposite directions in the vertical direction.

[0011] Furthermore, the third driving component includes a first hydraulic cylinder and a second hydraulic cylinder. The first hydraulic cylinder is fixedly mounted on the mounting bracket and is used to drive the first tool to rise and fall. The second hydraulic cylinder is fixedly mounted on the support frame and is used to drive the second tool to rise and fall.

[0012] Furthermore, the limiting component includes a plurality of limiting plate assemblies spaced apart along the circumference of the friction roller; each limiting plate assembly includes two first limiting plates and a second limiting plate located between the two first limiting plates, the first limiting plates being disposed on the inner wall of the friction roller, and the second limiting plate being disposed on the outer wall of the rotating roller;

[0013] The elastic element is a first spring, one end of which is connected to the first limiting plate and the other end of which is connected to the second limiting plate.

[0014] Furthermore, the first driving component is a third hydraulic cylinder, which is fixedly mounted on the mounting bracket to drive the lifting frame to move vertically up and down.

[0015] Furthermore, the second driving component includes a drive motor and a drive roller, the drive roller being located above the friction roller and in rolling contact with the friction roller, and the drive motor being used to drive the drive roller to rotate.

[0016] Furthermore, a movable seat is vertically slidably mounted on the lifting frame, and both the drive motor and the drive roller are mounted on the movable seat. A second spring is mounted on the lifting frame to drive the movable seat to move downward.

[0017] Furthermore, the end of the rotating roller is provided with several ratchet blocks, and a third spring is provided inside the rotating roller to drive the ratchet blocks to rotate and protrude from the outside of the rotating roller. The lifting frame is provided with a ratchet groove, which can cooperate with the ratchet blocks protruding from the rotating roller to restrict the unidirectional rotation of the rotating shaft.

[0018] The beneficial effects of this utility model are as follows: When cutting breathable fabric on the processing table, the lifting frame is first lowered so that the friction roller presses on the fabric. During the rotation of the drive roller, the friction roller is driven to rotate as a whole. The friction rollers on both sides of the cutter assembly rotate synchronously in the opposite direction, so that the fabric position corresponding to the cutter assembly is tensioned. After tensioning is completed, the drive roller stops rotating. Since the rotating roller inside the friction roller restricts unidirectional reversal, the friction roller is reversed at a certain angle relative to the rotating roller under the elastic force of the elastic element. Thus, after ensuring that the fabric is tensioned, the tensioned fabric can also be relaxed, so that the fabric remains flat and not tight when the cutter assembly cuts the fabric, thereby improving the final cutting effect of the fabric.

[0023] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0024] This application discloses a breathable fabric cutting device for sports shoe production, referring to... Figure 1The system includes a support frame 1, with a processing table 11 on top. Fabric is placed on the processing table 11. A mounting bracket 12, shaped like a gate, is fixedly installed above the processing table 11. A cutting tool assembly for cutting the fabric is located between the mounting bracket 12 and the processing table 11. Tensioning components 3 for tensioning the fabric are located on both sides of the cutting tool assembly on the mounting bracket 12. Specifically, the tensioning component 3 includes a lifting frame 31. A first driving component for vertically raising and lowering the lifting frame 31 is provided on the mounting bracket 12. The first driving component can be a third hydraulic cylinder 6, which is bolted to the mounting bracket 12. The third hydraulic cylinder 6 drives the lifting frame 31 to vertically raise and lower. A guide rod can be provided on the lifting frame 31, which cooperates with the mounting bracket 12 to keep the lifting frame 31 vertically raised and lowered.

[0025] Two rotating rollers 32 are arranged in parallel on the lifting frame 31, located on both sides of the cutter assembly. Both ends of the rotating rollers 32 are unidirectionally rotatably connected to the lifting frame 31, and the lower part of the rotating rollers 32 rotates away from the cutter assembly. A friction roller 33 is coaxially sleeved on the outer side of the rotating rollers 32. The friction roller 33 is used to contact the fabric. A limiter is provided on the rotating rollers 32 to limit the rotation range of the friction rollers 33 relative to the rotating rollers 32. A second driving member is provided on the lifting frame 31 to drive the friction rollers 33 to rotate by friction. An elastic member is provided on the rotating rollers 32 to drive the bottom of the friction rollers 33 to rotate towards the cutter assembly.

[0026] In use, the first drive unit on the mounting bracket 12 drives the lifting frame 31 to descend, causing the two friction rollers 33 to press against the fabric on both sides of the cutter assembly. Driven by the second drive unit, the friction rollers 33 on both sides of the cutter assembly rotate, stretching and tensioning the fabric towards both sides of the cutter assembly. During the tensioning process, the rotating roller 32 maintains unidirectional rotation. After the tensioning operation is completed, the second drive unit stops, and under the elastic force of the elastic element, pushes the friction rollers 33 to rotate in the opposite direction by a certain angle. This allows the fabric to be fully tensioned and flattened, and then the friction rollers 33 rotate in the opposite direction by a certain angle, allowing the fabric to relax from a fully taut state. When the cutter assembly cuts the fabric, this effectively avoids flyaways and delamination caused by tension at the cut point, improving the cutting effect.

[0027] Specifically, the tool assembly includes a first tool 21 and a second tool 22. Slide rails are provided on both the mounting bracket 12 and the support frame 1. The first tool 21 and the second tool 22 are vertically slidably mounted on the mounting bracket 12 and the support frame 1, respectively. The cutting edges of the first tool 21 and the second tool 22 face each other and are staggered. A mounting opening is provided on the machining table 11 below the first tool 21. The support frame 1 is provided with a third driving member for driving the first tool 21 and the second tool 22 to move synchronously and in opposite directions in the vertical direction.

[0028] The third driving component includes a first hydraulic cylinder 23 and a second hydraulic cylinder 24. The first hydraulic cylinder 23 is fixedly mounted on the mounting bracket 12 by bolts, and the second hydraulic cylinder is fixedly mounted on the support frame 1 by bolts. The first hydraulic cylinder 23 and the second hydraulic cylinder 24 are used to drive the first tool 21 and the second tool 22 to move vertically up and down, respectively.

[0029] Reference Figure 2 In this embodiment, a plurality of ratchet blocks 81 are rotatably provided at the end of the rotating roller 32. A third spring 82 is provided inside the rotating roller 32 to drive the ratchet blocks 81 to rotate and protrude outward from the outside of the rotating roller 32. A ratchet groove 83 is provided on the lifting frame 31. The ratchet groove 83 can cooperate with the ratchet blocks 81 protruding from the rotating roller 32 to restrict the unidirectional rotation of the rotating roller 32. The third spring 82 pushes the ratchet blocks 81 to protrude out of the rotating roller 32 and cooperate with the ratchet groove 83. When the lower part of the rotating roller 32 rotates in the forward direction away from the tool assembly, the ratchet blocks 81 and the ratchet groove 83 cooperate to squeeze the third spring 82, so that the rotating roller 32 can rotate smoothly. When the rotating roller 32 has a tendency to reverse, the ratchet blocks 81 cannot reverse under the restriction of the ratchet groove 83, so that the elastic element can smoothly push the friction roller 33 to rotate in the opposite direction relative to the rotating roller 32.

[0030] Reference Figure 3 In this embodiment, the limiting components include a first limiting plate 41 and a second limiting plate 42. The first limiting plate 41 is fixedly disposed on the side end face of the friction roller 33, and two first limiting plates 41 are spaced apart along the rotation axis. The second limiting plate 42 is fixedly disposed on the outer wall of the rotating roller 32, and the second limiting plate 42 is located between the two first limiting plates 41. The elastic element is a first spring 5, one end of which is connected to the first limiting plate 41, and the other end is connected to the second limiting plate 42. By limiting the second limiting plate 42 with the first limiting plate 41, the maximum rotation angle of the friction roller 33 relative to the rotating roller 32 can be limited, preventing the friction roller 33 from reversing by a large angle under the action of the elastic element, which would cause the fabric between the two friction rollers 33 to wrinkle again. When the friction roller 33 is driven to rotate forward under the force of the second driving element, the friction roller 33 overcomes the elastic force of the elastic element to compress the first spring 5, and rotates closer to the first limiting plate 41 through the second limiting plate 42, pushing the first limiting plate 41 and the rotating roller 32 to rotate.

[0031] The second driving component includes a drive motor 71 and a drive roller 72. The drive roller 72 is located above the friction roller 33 and makes rolling contact with the friction roller 33. The drive motor 71 is used to drive the drive roller 72 to rotate. During the rotation of the drive roller 72, the friction roller 33 can be driven to rotate through friction. When the fabric is stretched to its limit, the drive roller 72 and the friction roller 33 can slip to prevent the friction roller 33 from continuously rubbing against or even damaging the fabric.

[0032] Furthermore, a vertical groove is provided on the lifting frame 31, and a movable seat is vertically slidably arranged in the groove. The drive motor 71 and the drive roller 72 are both mounted on the movable seat. A second spring 74 is provided on the lifting frame 31 to drive the movable seat to move downward. By providing the second spring 74, the movable seat has a flexible lifting range. When slippage occurs between the drive roller 72 and the friction roller 33, the movable seat can push the second spring 74 to compress, so that the drive roller 72 and the friction roller 33 can be smoothly separated, avoiding excessive wear between the drive roller 72 and the friction roller 33.
