Description

Technical Field

[0001] This invention belongs to the field of down jacket processing technology, specifically a down jacket fabric scratch positioning and cutting device. Background Technology

[0002] The outer layer of a down jacket is made of fabric, which is the material used to make clothing. Fabric not only interprets the style and characteristics of clothing, but also directly affects the color and shape of the clothing, presenting its own noble perfection and soft feel. In the processing of down jacket fabric, the cutting process is essential.

[0003] Currently, traditional down jacket fabric scratch positioning cutting equipment involves placing the fabric to be cut on the surface of a vacuum adsorption table, then starting the vacuum pump. The vacuum pump then creates a negative pressure environment inside the vacuum adsorption table, which adsorbs and fixes the fabric, ensuring that the fabric will not move randomly during the subsequent cutting process. After the fabric is fixed, the cutting component is driven to make precise cuts along the cutting lines pre-marked on the fabric surface.

[0004] However, in actual use, especially in the fabric laying process, many factors can lead to problems. On the one hand, down jacket fabric is relatively soft and thin, making it difficult to lay it completely evenly and flat manually. Slightly uneven force applied by the workers or squeezing and folding of the fabric during handling can easily cause slight undulations and wrinkles on the fabric surface. When wrinkles appear during vacuum adsorption and fixing, the height of the fabric at the wrinkled area is inconsistent with that at the flat area when the cutting component cuts along the cutting line, resulting in uneven cutting depth. This leads to uneven edges and inaccurate dimensions of the cut down jacket fabric, greatly reducing the cutting quality. Summary of the Invention

[0005] To address the problems mentioned in the background section, this invention provides a down jacket fabric scratch positioning and cutting device.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a down jacket fabric scratch positioning and cutting device, comprising a main body, a fabric vacuum adsorption table, and a cutting assembly, and further comprising: The smoothing mechanism is located on both sides inside the main body; The driving component is located at the top of the main body; The smoothing mechanism includes limiting rods fixedly connected to both sides inside the main body. A mounting plate is slidably fitted on the surface of the limiting rod. Two gears are rotatably connected inside both ends of the mounting plate. A swing rod is fixedly installed at the bottom end of each of the two gears. A rack and a rack that mesh with the gears are fixedly installed at the bottom end of the limiting rod. The rack and rack are designed to be in opposite directions.

[0007] Preferably, the drive assembly includes a motor fixedly connected to the top of the main body. A bidirectional lead screw is fixedly installed at the output end of the motor. A threaded block is threaded onto the surface of the bidirectional lead screw, and the threaded block is fixedly connected to the mounting plate. A vacuum pump and an adsorption table generate strong suction to fix the fabric and prevent displacement. After fixing, the drive motor drives the bidirectional lead screw to rotate. Because it is threadedly connected to the threaded block, the threaded block slides on its surface, causing the two mounting plates to move towards each other on the limit rod, which in turn drives the gear to move. The gear meshes with rack one on both sides of the main body of the equipment in a longitudinal array. When moving, the two gears rotate towards each other along rack one, causing the swing rod to rotate. At a certain position, the gear meshes with rack two. Because rack two is facing rack one, the gear rotates in the opposite direction. The swing rod rotates repeatedly to smooth out wrinkles. Then, it drives the cutting assembly consisting of a slide rail, a lifting cylinder, and a cutting blade assembly. The lifting cylinder is operated to make the cutting blade assembly descend and fit against the fabric, moving smoothly along the cutting line for precise cutting, thereby improving the cutting quality of the fabric.

[0008] Preferably, it further includes: A tension adjustment mechanism is provided at the top of the main body. The tension adjustment mechanism includes a fixed shell fixedly connected to the top of the main body. An elastic element is fixedly installed inside the fixed shell. A sealing cylinder is fixedly installed at one end of the elastic element. A connecting pipe is fixedly installed at the bottom end of the outer surface of the sealing cylinder. An adsorption head is fixedly installed at the bottom end of the connecting pipe. The extraction component is located inside the sealed cylinder.

[0009] Preferably, the extraction assembly includes a sealing block slidably connected inside the sealing cylinder. A connecting rod is fixedly installed on one side of the sealing block, and a moving rod is fixedly installed at one end of the connecting rod. The sealing block and the sealing cylinder are elastically connected by an elastic element. The installation plate moves, pushing the moving rod, connecting rod, and sealing block to slide inside the sealing cylinder. When the sealing block moves, it squeezes the sealing cylinder, and the surface of the connecting rod tightly engages and adheres to the sealing cylinder. Because the connecting pipe is connected to the sealing cylinder, when the sealing cylinder is squeezed, it will draw air from the connecting pipe and the suction head to form a negative pressure, causing the suction head to tightly adhere to the fabric surface. When the sealing cylinder is compressed to its limit, the sealing block pushes it to move as a whole. During this process, the sealing cylinder compresses the elastic element, which drives the connecting pipe and the suction head to move. The suction head is located at the four corners of the fabric, which can pull the fabric to increase tension. In conjunction with the smoothing mechanism, it can process the fabric from different angles, preventing wrinkles from all directions and ensuring the cutting quality.

[0010] Preferably, a damping block is fixedly installed inside the mounting plate on the surface of the gear. The surface of the damping block is in contact with the surface of the gear, and the damping blocks are distributed in an array on the surface of the gear. By utilizing the direct contact between the surface of the damping block and the gear, and the surface being rough, a strong frictional force can be generated when the two are in contact. This frictional force enhances the damping effect of the gear rotation. When the gear moves away from the surface of the rack, this damping can effectively prevent it from resetting due to inertia and other factors, thereby ensuring the stability of the equipment operation.

[0011] Preferably, the bottom end of the movable rod is circular, and the inner wall of the sealing cylinder contacts the surface of the connecting rod. The circular design of the bottom end of the movable rod reduces friction with the mounting plate; the inner wall of the sealing cylinder contacts the connecting rod, supporting the stable movement of the movable rod.

[0012] Preferably, the fixing shell is designed with an inclination, and the inner wall of the fixing shell is in contact with the surface of the moving rod. The inclination of the fixing shell allows the moving rod to move naturally along its inclination direction, which can guide the adsorption head to apply appropriate tension and pull from the four corners of the fabric, keeping the fabric flat during processing.

[0013] Preferably, there is a gap between the connecting tube and the moving rod, and the connecting tube is made of rigid PVC material. By utilizing the gap between the moving rod and the connecting tube, the connecting tube does not interfere with the movement of the moving rod when it moves. Moreover, the connecting tube is made of rigid PVC material, which can stably drive the suction head and effectively pull the four corners of the fabric.

[0014] Preferably, a baffle is provided at the top of the gear, and the surface of the baffle is in contact with the top of the mounting plate. By providing a baffle at the top of the gear and having the surface of the baffle in contact with the top of the mounting plate, the baffle rotates along with the gear when it rotates, and at the same time, it can limit the gear and prevent it from coming out of the mounting plate during rotation.

[0015] Preferably, the elastic element one is provided with a telescopic rod inside, and both ends of the telescopic rod are fixedly connected to the fixed shell and the sealing cylinder. When the elastic element one is compressed or reset, the internal telescopic rod can support the sealing cylinder, which can effectively prevent the sealing cylinder from shifting its position due to uneven force or external interference during movement, and ensure that it always moves stably along the predetermined trajectory.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention uses a drive motor to rotate a bidirectional lead screw. As the lead screw rotates, a threaded block slides on its surface. The movement of the threaded block causes two mounting plates and gears to move together. As the gears move, the two gears rotate in opposite directions along rack one, simultaneously driving the swing arm to rotate. During the movement, the gears move away from the surface of rack one, and then the gears rotate in the opposite direction along rack two. In this repeated rotation process, the swing arm can smooth out the wrinkles generated when the fabric is laid. Finally, the drive motor makes the swing arm rotate back and forth, effectively smoothing out the wrinkles on the fabric surface and greatly improving the quality of fabric cutting. This invention continues to drive the mounting plate to move, using its own power to propel the moving rod forward, which in turn drives the connected connecting rod and sealing block to slide inside the sealing cylinder. When the sealing block moves, it squeezes the second elastic element. When the second elastic element is squeezed, it draws air from the connecting pipe and the suction head to form a negative pressure, allowing the suction head to tightly adhere to the fabric surface. When the second elastic element is compressed to its limit, the sealing block exerts force to push the whole thing to move. During this process, the sealing cylinder compresses the first elastic element, and the first elastic element, under force, drives the connecting pipe and the suction head to move. The suction head is located at the four corners of the fabric, which can pull the fabric to increase tension. This works in conjunction with the smoothing operation of the smoothing mechanism to process the fabric from different angles, avoiding wrinkles from all directions and greatly ensuring the quality of the fabric cutting.

Detailed Implementation

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] like Figures 1 to 8 As shown, the present invention provides a down jacket fabric scratch positioning and cutting device, including a main body 100, a fabric vacuum adsorption table 200, and a cutting component 300, and further including: The smoothing mechanism 400 is located on both sides inside the main body 100; The drive component 500 is located at the top of the main body 100; The smoothing mechanism 400 includes a limiting rod 401 fixedly connected to both sides inside the main body 100. A mounting plate 402 is slidably fitted onto the surface of the limiting rod 401. Two gears 403 are rotatably connected inside both ends of the mounting plate 402. A swing rod 404 is fixedly installed at the bottom end of each of the two gears 403. A rack 405 and a rack 406 that mesh with the gears 403 are fixedly installed at the bottom end of the limiting rod 401. The rack 405 and the rack 406 are designed to be in opposite directions.

[0021] like Figure 3 and Figure 4 As shown, the drive assembly 500 includes a motor 501 fixedly connected to the top of the main body 100. A bidirectional lead screw 502 is fixedly installed at the output end of the motor 501. A threaded block 503 is threadedly fitted on the surface of the bidirectional lead screw 502, and the threaded block 503 is fixedly connected to the mounting plate 402.

[0022] The above solution involves the operator placing the fabric to be cut on top of the fabric vacuum adsorption table 200. The fabric vacuum adsorption table 200 is a clever combination of a vacuum pump and vacuum suction cups. The operator starts the vacuum pump, generating a powerful suction that instantly adheres to the fabric, ensuring it doesn't shift during subsequent operations. After fixation, the drive motor 501 causes the connected bidirectional lead screw 502 to rotate. The bidirectional lead screw 502 is threadedly connected to the threaded block 503. This design allows for… When the bidirectional lead screw 502 rotates, the threaded block 503 slides on its surface. The movement of the threaded block 503 causes the two mounting plates 402 to move towards each other on the surface of the limit rod 401. Then the mounting plates 402 drive the gear 403 to move together. The gear 403 meshes with the rack 405. Every two racks 405 and rack 406 form a group and are arranged in a longitudinal array on both sides of the main body 100. As the gear 403 moves, the two gears 403 rotate towards each other along the rack 405, and at the same time drive the swing rod 404 to rotate. When it moves to a certain position, gear 403 moves away from the surface of rack 405 and engages with rack 406. Since rack 406 and rack 405 are designed to face each other, gear 403 rotates in the opposite direction along rack 406. During this repeated rotation, swing arm 404 can smooth out the wrinkles generated when the fabric is laid out. Then it drives the cutting assembly 300, which consists of a slide rail, a lifting cylinder and a cutting blade assembly. The operator controls the lifting cylinder to make the cutting blade assembly slowly descend and accurately fit against the fabric surface. Then, the cutting blade assembly moves smoothly along the cutting lines drawn on the fabric surface in advance to make precise cuts. Finally, the drive motor 501 makes the swing arm 404 reciprocate, effectively smoothing out the wrinkles on the fabric surface and greatly improving the quality of fabric cutting.

[0023] like Figure 7 and Figure 8 As shown, it also includes: Tension adjustment mechanism 600 is disposed at the top of main body 100. Tension adjustment mechanism 600 includes fixed shell 601 fixedly connected to the top of main body 100. An elastic element 602 is fixedly installed inside the fixed shell 601. A sealing cylinder 603 is fixedly installed at one end of the elastic element 602. A connecting pipe 604 is fixedly installed at the bottom end of the outer surface of the sealing cylinder 603. An adsorption head 605 is fixedly installed at the bottom end of the connecting pipe 604. Extraction component 700 is located inside sealing cylinder 603.

[0024] like Figure 7 and Figure 8As shown, the extraction assembly 700 includes a sealing block 701 that is slidably connected inside the sealing cylinder 603. A connecting rod 702 is fixedly installed on one side of the sealing block 701, and a moving rod 703 is fixedly installed on one end of the connecting rod 702. The sealing block 701 and the sealing cylinder 603 are elastically connected by an elastic element 704.

[0025] Using the above scheme: Through the design of the tension adjustment mechanism 600 and the extraction component 700, after the swing rod 404 smooths out the wrinkles on the fabric surface, it can continue to drive the mounting plate 402 to move. As the mounting plate 402 moves, one side of it slowly contacts the surface of the moving rod 703. At the moment of contact, the moving mounting plate 402 pushes the moving rod 703 forward with its own power. The moving rod 703 drives the connecting rod 702 and the sealing block 701 connected to it to slide together inside the sealing cylinder 603. During the movement of the sealing block 701, it will exert a squeezing effect on the elastic element 704, and the surface of the connecting rod 702 will be tightly engaged and adhered to the sealing cylinder 603. Meanwhile, since the connecting pipe 604 is connected to the sealing cylinder 603, when the sealing cylinder 603 is squeezed, it will draw out the air inside the connecting pipe 604 and the suction head 605, forming a negative pressure environment. This allows the suction head 605 to tightly adhere to the surface of the fabric. When the elastic element 704 is compressed to its limit, the sealing block 701 will exert force to push the sealing cylinder 603 to move as a whole. During the movement, the sealing cylinder 603 compresses the elastic element 602. After being subjected to force, the elastic element 602 drives the connecting pipe 604 and the suction head 605 to move together. Because the suction head 605 is set at the four corners of the fabric, it can pull the fabric, effectively increasing the tension of the fabric. Then, in conjunction with the smoothing operation of the smoothing mechanism 400, the fabric is processed from different angles, avoiding wrinkles in the fabric in all directions and greatly ensuring the quality of the fabric cutting.

[0026] like Figure 5 and Figure 6 As shown, a damping block 801 is fixedly installed inside the mounting plate 402 on the surface of the gear 403. The surface of the damping block 801 is in contact with the surface of the rotating rod at the top of the gear 403, and the damping blocks 801 are arrayed on the surface of the rotating rod. The bottom end of the moving rod 703 is circular, and the inner wall of the sealing cylinder 603 is in contact with the surface of the connecting rod 702.

[0027] The above solution employs the following: The damping block 801 is designed so that its surface directly contacts the rotating rod at the top of the gear 403. Its rough surface generates strong friction when in contact with the rotating rod, increasing the damping effect of the gear 403's rotation. This effectively prevents the gear 403 from resetting due to inertia or other factors when it moves away from the rack 405 surface, ensuring the stability of the equipment. The moving rod 703, with its circular bottom end, reduces friction with the mounting plate 402, ensuring the mounting plate 402 can stably push the moving rod 703. Furthermore, the inner wall of the sealing cylinder 603 contacts the surface of the connecting rod 702, providing support and ensuring stable movement of the moving rod 703.

[0028] like Figure 1 and Figure 7 As shown, the fixed shell 601 is designed with an inclination, and the inner wall of the fixed shell 601 is in contact with the surface of the moving rod 703. There is a gap between the connecting pipe 604 and the moving rod 703, and the connecting pipe 604 is made of rigid PVC material.

[0029] The above solution employs the following: Due to the inclined design of the fixed housing 601, the moving rod 703 naturally moves along the inclined direction of the fixed housing 601, guiding the adsorption head 605 to apply appropriate pulling force, effectively pulling the fabric from its four corners and ensuring the fabric remains flat during processing. Furthermore, the design of the moving rod 703 and the connecting tube 604 ensures that the connecting tube 604 does not interfere with the movement of the moving rod 703. Since the connecting tube 604 is made of rigid PVC, it ensures that the connecting tube 604 can stably drive the adsorption head 605 to pull the fabric from its four corners.

[0030] like Figure 5 and Figure 8 As shown, a baffle is provided at the top of the gear 403, and the surface of the baffle is in contact with the top of the mounting plate 402. A telescopic rod is provided inside the elastic element 602, and both ends of the telescopic rod are fixedly connected to the fixed shell 601 and the sealing cylinder 603.

[0031] The above solution is adopted as follows: Through the design of gear 403, since a baffle is provided at the top of gear 403 and the surface of the baffle is in contact with the top of mounting plate 402, the baffle can rotate along with gear 403 during rotation and can limit gear 403, preventing gear 403 from disengaging from the interior of mounting plate 402 when it rotates. Through the design of elastic element 602, when elastic element 602 is compressed or reset, its internal telescopic rod can support sealing cylinder 603, effectively preventing sealing cylinder 603 from shifting position due to uneven force or external interference during movement, and ensuring that sealing cylinder 603 always moves along the predetermined trajectory.

[0032] Working principle and usage process of this invention: First, the operator needs to lay the fabric to be cut on the top of the fabric vacuum adsorption table 200. After laying, the fabric vacuum adsorption table 200 is started. A strong adsorption force is generated instantly, firmly fixing the fabric to the table surface. After the fabric is fixed, the drive motor 501 starts to run, driving the bidirectional lead screw 502 to rotate. The bidirectional lead screw 502 and the threaded block 503 are connected by threads. When the bidirectional lead screw 502 rotates, the threaded block 503 will slide smoothly along its surface. The movement of the threaded block 503 further drives the two mounting plates 402 and the gear 403 to move together. As the gear 403 moves, the two gears 403 rotate towards each other along the pre-set rack 1 405, while driving the swing rod 404 to rotate. During the movement, the gear 403 will gradually move away from the surface of rack 1 405, and then rotate in the opposite direction along rack 2 406. In this repeated rotation process, the swing rod 404 smooths out the wrinkles generated when the fabric is laid, making the fabric surface flat again.

[0033] After the swing rod 404 successfully smooths out the wrinkles on the fabric surface, it continues to drive the mounting plate 402 to move. The moving mounting plate 402, using its own power, pushes the moving rod 703 forward. The moving rod 703 drives the connecting rod 702 and the sealing block 701 to slide together inside the sealing cylinder 603. During the movement of the sealing block 701, it exerts a squeezing effect on the elastic element 704, while simultaneously drawing air from the connecting pipe 604 and the suction head 605, creating a negative pressure environment. This causes the suction head 605 to tightly adhere to the surface of the fabric. When the elastic element 704 is compressed to its limit, the sealing block 701 exerts force to push the sealing cylinder 603 to move as a whole, thereby further squeezing the elastic element. The elastic element 602 is compressed, and after being stressed, it drives the connecting tube 604 and the suction head 605 to move together. Since the suction head 605 is set at the four corners of the fabric, it can pull the fabric and effectively increase the fabric tension. This series of operations works in conjunction with the smoothing operation of the smoothing mechanism 400 to process the fabric from different angles and avoid wrinkles in the fabric in all directions. Finally, the cutting component 300 is driven to make the cutting blade group slowly descend and fit against the fabric surface. Then, the cutting blade group moves smoothly along the cutting lines drawn on the fabric surface in advance to make precise cuts. After this series of fine operations, the entire fabric cutting process is finally completed.
