Description

Technical Field

[0001] This utility model relates to the technical field of artificial leather winding equipment, and in particular to a cutting machine and PVC artificial leather winding equipment. Background Technology

[0002] In the production process of PVC artificial leather, winding is one of the key steps. Traditional PVC artificial leather winding equipment mostly uses a single winding roller design. When the winding roller is full, the machine needs to be stopped to change the roll. This not only interrupts the production process and reduces production efficiency, but may also cause quality problems such as wrinkles and deformation of the artificial leather due to the downtime. At the same time, the cutting of artificial leather during winding also has problems such as low cutting accuracy and inconvenient storage of cutting tools, which may cause safety hazards.

[0003] Therefore, we propose a cutting machine and a PVC artificial leather winding device. Utility Model Content

[0004] The main purpose of this utility model is to provide a cutting machine and a PVC artificial leather winding device to prevent production process interruptions and efficiency reduction caused by stopping the machine to change the roll when the traditional single winding roller design is full, and to avoid quality problems such as wrinkles and deformation of artificial leather caused by machine stoppage. At the same time, it prevents safety hazards caused by low cutting accuracy and inconvenient tool storage during winding and switching, thereby improving the continuity of PVC artificial leather production, production efficiency and product quality, and ensuring the safety of equipment use. It can effectively solve the problems in the background technology.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A cutting machine and a PVC artificial leather winding device include a frame. A first winding assembly and a second winding assembly are arranged sequentially from front to back on the rear inner side of the frame. The first winding assembly includes a first winding roller rotatably connected to the inner side of the frame. One end of the first winding roller passes through the frame and is fixedly connected to a first positioning plate. A plurality of positioning blocks are arranged in a circular array on the side of the first positioning plate away from the frame. A support is fixedly connected to the outer wall of the frame near the first winding roller. A movable seat is moved back and forth on the upper end of the support. A motor is fixedly installed on the top of the movable seat. A second positioning plate is fixedly connected to the output shaft of the motor. The second positioning plate is provided with positioning holes that match the positioning blocks. Two take-up reels are fixedly connected to the outer side of the first take-up roller and located inside the frame. Each of the two take-up reels has a groove on its opposite side. Each of the two grooves has a sliding seat that slides up and down in fit. A crossbar is fixedly connected between the two sliding seats. A cutting blade is fixedly installed at the bottom end of the crossbar. A storage groove for accommodating the cutting blade is provided at the top end of the first take-up roller.

[0006] By adopting the above technical solution, the equipment uses a double take-up roller design. In the initial state, the PVC artificial leather passes through the channel between the cutting blade and the collection slot and is wound up by the second take-up roller. When the second take-up roller is fully wound up, the first cylinder pushes the moving seat to move, so that the positioning hole on the second positioning plate is precisely engaged with the positioning block on the first positioning plate. Then the motor is started, and the first take-up roller is driven to rotate through the transmission between the second and first positioning plates. At this time, the end of the PVC artificial leather is fixed on the first take-up roller, and the first take-up roller takes over the winding operation.

[0007] Furthermore, a channel for PVC artificial leather to pass through is provided between the cutting blade and the storage slot, and the storage slot is matched with the cutting blade.

[0008] By adopting the above technical solution, in the initial state, the PVC artificial leather passes through the channel between the cutting blade and the receiving groove. At this time, the cutting blade is in the initial position above the receiving groove, which does not affect the winding action of the second winding roller. When the second winding roller is full and needs to switch to the first winding roller, the cutting blade moves downward and embeds itself into the receiving groove. The cooperation of the two cuts the PVC artificial leather in the channel precisely. After cutting, the first winding roller begins to wind up the new PVC artificial leather.

[0009] Furthermore, the bottom end of the movable seat is fixedly connected to two limiting blocks, and the top of the support is provided with a limiting groove for limiting the limiting blocks and slidingly engaging with them.

[0010] By adopting the above technical solution, when the second take-up roller is fully wound and needs to be switched to the first take-up roller, the first cylinder pushes the movable seat to move on the support. The limiting block at the bottom of the movable seat slides along the limiting groove, ensuring that the movable seat drives the motor and the second positioning plate to move smoothly, so that the second positioning plate can accurately dock with the first positioning plate, ensuring the stable start of the first take-up roller. When the first take-up roller does not need to work, the first cylinder pulls the movable seat to reset, and the cooperation between the limiting block and the limiting groove also ensures the smoothness of the movement process.

[0011] Furthermore, a first cylinder is fixedly installed on the inner wall of one side of the support, and the telescopic end of the first cylinder passes through the support and is fixedly connected to the movable seat.

[0012] By adopting the above technical solution, in the initial state, the first cylinder is in the extended state, the second positioning plate is separated from the first positioning plate, the first take-up roller is not working, and the second take-up roller performs the winding alone. When the second take-up roller is fully wound, the first cylinder retracts, pushing the movable seat to move the second positioning plate towards the first positioning plate and achieve docking, so that the motor can drive the first take-up roller to rotate; when it is necessary to pause the operation of the first take-up roller or change the roll material, the first cylinder extends, pulling the movable seat and the second positioning plate to reset, so that the first take-up roller stops rotating.

[0013] Furthermore, each of the two winding reels has a mounting groove on one of its opposite sides, and the mounting groove is located directly above the slide groove.

[0014] By adopting the above technical solution, the mounting groove provides a stable mounting space for the second cylinder, allowing it to be fixed on the take-up reel and located directly above the slide groove. This ensures that the extension and retraction direction of the second cylinder is consistent with the sliding direction of the slide block in the slide groove, providing a structural basis for the precise up and down movement of the cutting blade and ensuring that the cutting action of PVC artificial leather can be completed smoothly when switching the take-up roller.

[0015] Furthermore, a second cylinder is fixedly installed at the bottom of the mounting groove, and the telescopic end of the second cylinder extends into the slide groove and is fixedly connected to the top of the slide block.

[0016] By adopting the above technical solution, in the initial state, the second cylinder is in a retracted state, and the slide block drives the cutting blade to be positioned above the receiving groove, without affecting the conveying of PVC artificial leather to the second take-up roller. When the second take-up roller is fully wound and needs to be switched, the second cylinder extends, pushing the slide block to slide downwards along the slide groove, causing the cutting blade to move downwards and embed into the receiving groove, completing the cutting of the PVC artificial leather; after cutting, the second cylinder retracts, driving the slide block and the cutting blade to return to their initial position, and the cutting blade is retracted to its initial position, without affecting the winding operation of the first take-up roller; when the equipment is not in use, the second cylinder remains in a retracted state, so that the cutting blade is stably stored above the receiving groove, avoiding damage caused by exposed blades.

[0017] Compared with the prior art, the present invention has the following beneficial effects: (1) The present invention provides a cutting machine and a PVC artificial leather winding device, which adopts a double winding roller design. When the second winding roller is fully wound, it can quickly switch to the first winding roller for winding through the cooperation of the first cylinder, motor and other components. There is no need to stop the machine to change the roll material, which effectively avoids production interruption and greatly improves the continuity of PVC artificial leather production and overall production efficiency.

[0018] (2) This utility model provides a cutting machine and a PVC artificial leather winding device. The cutting blade is precisely moved up and down by a second cylinder. Combined with the matching design of the storage groove and the cutting blade, it can accurately cut PVC artificial leather during winding and switching. When the equipment is not in use, the cutting blade can be stably stored above the storage groove, avoiding damage caused by exposed blades. This ensures both cutting quality and safety of equipment use. Attached Figure Description

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] To prevent production interruptions and efficiency reductions caused by shutdowns for material changes when the traditional single-roller design is full, and to avoid quality issues such as wrinkles and deformation in artificial leather caused by downtime; and to prevent safety hazards arising from low cutting accuracy and inconvenient tool storage during roll changes, thereby improving the continuity, efficiency, and product quality of PVC artificial leather production and ensuring equipment safety, such as… Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a cutting machine and a PVC artificial leather winding device include a frame 1. A first winding assembly 2 and a second winding assembly 3 are arranged sequentially from front to back on the inner rear side of the frame 1. The first winding assembly 2 includes a first winding roller 22 rotatably connected to the inner side of the frame 1. One end of the first winding roller 22 passes through the frame 1 and is fixedly connected to a first positioning plate 4. A plurality of positioning blocks 5 are arranged in a ring on the side of the first positioning plate 4 away from the frame 1. A support 21 is fixedly connected to the outer wall of the frame 1 near the first winding roller 22. A movable seat 6 is movable back and forth on the upper end of the support 21. A motor 7 is fixedly installed on the top of the movable seat 6. A second positioning plate 8 is fixedly connected to the output shaft of the motor 7. The second positioning plate 8 is provided with positioning holes 9 that match the positioning blocks 5. Two take-up reels 10 are fixedly connected to the outer side of the first take-up roller 22 and inside the frame 1. Each of the two take-up reels 10 has a groove 11 on its opposite side. Each of the two grooves 11 has a sliding seat 12 that slides up and down in each groove. A crossbar 13 is fixedly connected between the two sliding seats 12. A cutting blade 14 is fixedly installed at the bottom end of the crossbar 13. A storage groove 15 for accommodating the cutting blade 14 is provided at the top end of the first take-up roller 22.

[0026] In use, the equipment adopts a double take-up roller design. In the initial state, the PVC artificial leather passes through the channel between the cutting blade 14 and the storage groove 15 and is wound up by the second take-up roller. When the second take-up roller is fully wound up, the first cylinder 18 pushes the moving seat 6 to move, so that the positioning hole 9 on the second positioning plate 8 and the positioning block 5 on the first positioning plate 4 are precisely engaged. Then, the motor 7 is started, and the first take-up roller 22 is driven to rotate through the transmission between the second positioning plate 8 and the first positioning plate 4. At this time, the end of the PVC artificial leather is fixed on the first take-up roller 22, and the first take-up roller 22 takes over the winding operation.

[0027] For example, such as Figure 3 As shown, the present invention also includes a channel for PVC artificial leather to pass through between the cutting blade 14 and the storage groove 15, and the storage groove 15 is matched with the cutting blade 14.

[0028] In use, initially, the PVC artificial leather passes through the channel between the cutting blade 14 and the storage groove 15. At this time, the cutting blade 14 is in its initial position above the storage groove 15, which does not affect the winding action of the second winding roller. When the second winding roller is fully wound and needs to switch to the first winding roller 22, the cutting blade 14 moves downward and embeds itself into the storage groove 15. The cooperation of the two precisely cuts the PVC artificial leather in the channel. After cutting, the first winding roller 22 begins to wind up new PVC artificial leather.

[0029] For example, such as Figure 4 As shown, the present invention also includes two limiting blocks 16 fixedly connected to the bottom end of the movable seat 6, and a limiting groove 17 for limiting the limiting blocks 16 and slidingly engaging with the limiting blocks 16 is provided on the top of the support 21.

[0030] In use, when the second take-up roller is fully wound and it is necessary to switch to the first take-up roller 22, the first cylinder 18 pushes the movable seat 6 to move on the support 21. The limiting block 16 at the bottom of the movable seat 6 slides along the limiting groove 17 to ensure that the movable seat 6 drives the motor 7 and the second positioning plate 8 to move smoothly, so that the second positioning plate 8 can accurately dock with the first positioning plate 4, ensuring the stable start of the first take-up roller 22. When the first take-up roller 22 is not needed to work, the first cylinder 18 pulls the movable seat 6 to reset. The cooperation between the limiting block 16 and the limiting groove 17 also ensures the smoothness of the movement process.

[0031] For example, such as Figure 4 As shown, the present invention also includes a first cylinder 18 fixedly installed on the inner wall of one side of the support 21, and the telescopic end of the first cylinder 18 passes through the support 21 and is fixedly connected to the movable seat 6.

[0032] In the initial state of use, the first cylinder 18 is in the extended state, the second positioning plate 8 is separated from the first positioning plate 4, the first take-up roller 22 is not working, and the second take-up roller performs the winding alone. When the second take-up roller is fully wound, the first cylinder 18 retracts, pushing the movable seat 6 to move the second positioning plate 8 towards the first positioning plate 4 and achieve docking, so that the motor 7 can drive the first take-up roller 22 to rotate; when it is necessary to pause the operation of the first take-up roller 22 or change the roll, the first cylinder 18 extends, pulling the movable seat 6 and the second positioning plate 8 to reset, so that the first take-up roller 22 stops rotating.

[0033] For example, such as Figure 3 As shown, the present invention also includes mounting grooves 19 on opposite sides of the two winding reels 10, the mounting grooves 19 being located directly above the slide groove 11.

[0034] During use, the mounting groove 19 provides a stable mounting space for the second cylinder 20, allowing it to be fixed on the take-up reel 10 and located directly above the slide groove 11. This ensures that the extension and retraction direction of the second cylinder 20 is consistent with the sliding direction of the slide block 12 within the slide groove 11, providing a structural basis for the precise up and down movement of the cutting blade 14 and ensuring that the cutting action of PVC artificial leather can be completed smoothly when switching the take-up roller.

[0035] For example, such as Figure 3 As shown, the present invention also includes a second cylinder 20 fixedly installed at the bottom end of the mounting groove 19, the telescopic end of the second cylinder 20 extending into the slide groove 11 and fixedly connected to the top end of the slide block 12.

[0036] In operation, initially, the second cylinder 20 is in a retracted state, and the slide block 12 drives the cutting blade 14 to be positioned above the receiving groove 15, without affecting the conveying of PVC artificial leather to the second take-up roller. When the second take-up roller is fully wound and needs to be switched, the second cylinder 20 extends, pushing the slide block 12 to slide downwards along the slide groove 11, causing the cutting blade 14 to move downwards and embed into the receiving groove 15, completing the cutting of the PVC artificial leather. After cutting, the second cylinder 20 retracts, driving the slide block 12 and the cutting blade 14 to return to their original position, and the cutting blade 14 is retracted to its initial position, without affecting the winding operation of the first take-up roller 22. When the equipment is not in use, the second cylinder 20 remains in a retracted state, so that the cutting blade 14 is stably stored above the receiving groove 15, avoiding damage caused by exposed blades.

[0037] It should be noted that this utility model is a cutting machine and a PVC artificial leather winding device, which adopts a double winding roller design. In the initial state, the second cylinder 20 retracts, the cutting blade 14 is located above the storage groove 15, and the PVC artificial leather passes through the channel between the cutting blade 14 and the storage groove 15. The first cylinder 18 extends, and the second positioning plate 8 separates from the first positioning plate 4, and is wound up separately by the second winding roller. When the second winding roller is fully wound, the first cylinder 18 retracts, pushing the moving seat 6 to move. The bottom limiting block 16 of the moving seat 6 slides along the limiting groove 17 of the support 21, so that the second positioning plate 8 and the first positioning plate 4 are precisely aligned. Subsequently, motor 7 starts, driving the first take-up roller 22 to rotate via the second positioning plate 8 and the first positioning plate 4. At the same time, the second cylinder 20 extends, pushing the slide 12 down along the slide groove 11. The cutting blade 14 is embedded in the storage groove 15 to complete the cutting of the PVC artificial leather, fixing the end of the artificial leather on the first take-up roller 22, which then takes over the winding. After cutting, the second cylinder 20 retracts, driving the slide 12, crossbar 13 and cutting blade 14 to return to their original position, without affecting the winding of the first take-up roller 22. When the equipment is not in use, the second cylinder 20 remains retracted, and the cutting blade 14 is stored above the storage groove 15 to prevent the blade from being exposed and damaged.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
