Description

Technical Field

[0001] This invention relates to the field of warp-knitted fabric slitting and winding technology, and more particularly to a slitting and winding device for warp-knitted fabric. Background Technology

[0002] Warp-knitted fabrics are widely used in clothing, home textiles, and industrial textiles due to their advantages such as good elasticity, high stability, and fast production efficiency. In the production and processing of warp-knitted fabrics, slitting and winding are crucial steps connecting fabric weaving and subsequent finished product processing. Wide warp-knitted fabrics need to be slitted into narrower widths according to actual usage requirements and simultaneously wound neatly to facilitate subsequent cutting, printing, or further processing. Currently, the warp-knitted fabric slitting and winding devices used in the industry still have several technical shortcomings in actual operation: Firstly, insufficient slitting accuracy. Because warp-knitted fabrics often have a certain degree of elasticity, slight deviations during fabric transport and fluctuations in tension can easily occur during the slitting process. Firstly, the slitting and winding processes suffer from several problems. Firstly, the slitting cuts often have rough edges and are skewed, affecting the dimensional accuracy and appearance quality of subsequent products. Secondly, tension control is unstable. Existing devices often use a single tension adjustment mechanism, which is insufficient to adapt to the varying tension requirements of warp-knitted fabrics with different thicknesses and elastic coefficients during the slitting and winding process. When the tension is too low, the fabric is prone to wrinkles and stacking; when the tension is too high, the fabric is easily stretched and deformed, damaging its physical properties. Thirdly, the automation level is low. Some devices still require manual intervention to adjust parameters such as slitting width and winding speed, which not only increases the labor intensity of operators but also easily leads to inconsistent slitting and winding parameters due to human error, reducing production efficiency and product consistency.

[0003] During the use of the slitting and winding device, the warp-knitted fabric needs to be slitted. Therefore, the two ends of the warp-knitted fabric need to be pressed down and fixed. Otherwise, the warp-knitted fabric will shift when slitted, making it impossible to cut accurately. In addition, the position of the fully automatic laser cutting machine also needs to be adjusted up and down. Otherwise, the fully automatic laser cutting machine will not be able to adapt to fabrics of different thicknesses, which will affect the cutting quality and efficiency. Summary of the Invention

[0004] This invention relates to a slitting and winding device for warp-knitted fabrics. When an electric cylinder pushes a support plate and a fully automatic laser cutter downwards, the protective gravity plates at both ends of the support plate move downwards simultaneously, causing the stabilizing plate at the bottom to smoothly press against the surface of the warp-knitted fabric. This achieves reliable and uniform downward pressure and fixation of both ends of the warp-knitted fabric, effectively preventing the fabric from shifting or wrinkling during the cutting process. Subsequently, the fully automatic laser cutter continues to descend precisely, quickly adjusting the distance between itself and the warp-knitted fabric to the optimal cutting position. This not only significantly improves the laser focus positioning accuracy and cutting consistency but also avoids cut deformation or energy scattering caused by fabric loosening. Ultimately, this ensures the flatness of the slitting edge of the warp-knitted fabric and processing efficiency, while reducing manual adjustment errors and equipment operation risks.

[0005] In a first aspect, the present invention provides a slitting and winding device for warp-knitted fabrics, specifically comprising: a worktable; two fixing slots at the rear end of the worktable; rectangular slots at both ends of the worktable, and two threaded slots at the outer ends of the rectangular slots; fixing bases fixedly installed at the two fixing slots of the worktable, and grooves at the upper ends of the fixing bases; the structures on the two fixing bases are identical; and symmetrical fixing plates are fixedly installed at the rear end of the top of the worktable, and the structures on the two fixing plates are identical. A fixed frame is fixedly installed at the rectangular slots at both ends of the workbench, and a slot is opened at the rear end of the fixed frame; a support slot is opened at the front end of the fixed frame; a through electric cylinder is fixedly installed at the middle of the upper end of the fixed frame; a bearing plate is fixedly installed at the lower end of the electric cylinder, and adjustment ports are opened at the middle of both ends of the bearing plate; a fully automatic laser cutting machine is slidably installed at the bottom of the bearing plate; and symmetrical guide rods are fixedly installed at both ends of the top of the bearing plate. The bearing plate has parallel track holes at both ends. Protective gravity plates are slidably installed at both ends of the lower end of the electric cylinder. Stabilizing plates are fixedly installed at the bottom of the two protective gravity plates. Track plates are fixedly installed at both ends of the two protective gravity plates. Symmetrical connecting blocks are fixedly installed at the top of the two protective gravity plates. Bearing rings are fixedly installed on the side walls of the connecting blocks. Threaded rods are fixedly installed in the inner rings of the four bearing rings. Threaded cylinders are rotatably fitted onto the opposite ends of the left and right threaded rods.

[0006] Furthermore, a support frame is fixedly installed at the top center of the workbench, and a limiting frame is installed at both ends of the upper end of the support frame.

[0007] Furthermore, a synchronous motor is fixedly installed in the groove of the fixed base, and a coupling is fixedly connected to the shaft of the synchronous motor.

[0008] Furthermore, a driven shaft is fixedly connected to the other end of the coupling, and a fabric roller is installed on the annular sidewall of the driven shaft.

[0009] Furthermore, the lower end of the fixed upright plate is provided with a through shaft hole, and an extension plate is fixedly installed on the front side of the upper end of the fixed upright plate. The front end of the extension plate is provided with a through round hole, and through anti-detachment holes are provided on both sides of the round hole at the front end of the extension plate.

[0010] Furthermore, a through-hole electric rod is fixedly installed at the circular hole of the extension plate, and an arc-shaped limiting plate is fixedly installed at the lower end of the electric rod. Two vertically upward anti-detachment rods are fixedly installed at the upper end of the limiting plate.

[0011] Furthermore, through guide holes are provided at the four corners of the upper end of the fixed frame, and side plates are fixedly installed on the outer side of the lower end of the fixed frame. Through bolts are rotatably inserted at both ends of the side plates, and a dust collection box is installed at the slot of the fixed frame.

[0012] Furthermore, symmetrical stabilizing blocks are fixedly installed at the upper and lower ends of the dust collection box, and a through screw is inserted in the middle of the stabilizing block. A support beam is fixedly installed at the support slot at the front end of the fixed frame, and a hair dryer is fixedly installed in the middle of the support beam.

[0013] This invention provides a slitting and winding device for warp-knitted fabrics, which has the following beneficial effects: In this invention, when the slitting and winding device is in use, the electric cylinder pushes the support plate and the fully automatic laser cutter downwards, and the protective gravity plates at both ends of the support plate move downwards simultaneously, so that the stabilizing plate at the bottom presses smoothly onto the surface of the warp-knitted fabric. This achieves reliable and uniform downward pressure and fixation of both ends of the warp-knitted fabric, effectively preventing the fabric from shifting or wrinkling during the cutting process. Subsequently, the fully automatic laser cutter continues to descend precisely, quickly adjusting the distance between itself and the warp-knitted fabric to the optimal cutting position. This not only significantly improves the laser focus positioning accuracy and cutting consistency, but also avoids cut deformation or energy scattering caused by loose fabric. Ultimately, this ensures the flatness of the slitting edge of the warp-knitted fabric and processing efficiency, while reducing manual adjustment errors and equipment operation risks.

[0014] Furthermore, by simultaneously rotating the two threaded cylinders clockwise, the threaded rods at both ends can be driven to retract inward in sync, thereby efficiently pulling the protective gravity plates on both sides in opposite directions, quickly shortening the gap between the plates, and enhancing the compactness and stability of the overall structure. Conversely, by simultaneously rotating the threaded cylinders counterclockwise, the threaded rods can be pushed outward, causing the protective gravity plates to move backward and rapidly increasing the gap. While adjusting the plate spacing, the bottom stabilizing plate is also moved accordingly, allowing it to accurately press down and adhere tightly to the surface of the warp-knitted fabric. This effectively improves the tension control and stable support of the fabric, preventing displacement or loosening during processing, and ensuring operational stability and consistency in fabric processing quality.

[0015] Furthermore, the limiting plate is first pushed downwards using an electric lever, ensuring its sidewalls fit tightly against the fabric roller's sidewalls. This effectively blocks and limits the fabric roller, preventing axial shift or radial wobble during high-speed rotation. This ensures a consistently smooth and uniform output of the warp-knitted fabric. The fabric is then drawn from the right-hand fabric roller and wound onto the left-hand fabric roller. Simultaneously, two synchronous motors are activated, driving the driven shaft and fabric roller to rotate in tandem. This design not only achieves efficient right-to-left transfer of the warp-knitted fabric but also ensures constant tension, no shaking, and no wrinkles during transmission through dual-motor synchronous drive, significantly improving the neatness of the fabric winding and overall production efficiency.

[0016] After the fully automatic laser cutting machine completes the slitting of the warp-knitted fabric below, two protective gravity plates above the fabric immediately press down to firmly fix it, ensuring the fabric remains stable during subsequent processing. Subsequently, the system simultaneously starts the blower and dust collection box. The blower generates directional airflow to blow debris, dust, and other impurities generated during the slitting process backward, removing them from the processing area and preventing accumulation. At the same time, the dust collection box at the rear quickly and efficiently absorbs and collects the blown-out debris. The combined effect of these two processes achieves rapid and thorough removal of impurities from the surface of the support frame. This process not only significantly improves the cleanliness of the cut fabric, avoiding secondary pollution or the inconvenience of manual cleaning, but also improves the continuity, efficiency, and product quality consistency of the slitting operation.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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, not all, of the embodiments of the present invention. Based on the described 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.

[0021] Example 1: Please refer to Figures 1 to 9 : This invention proposes a slitting and winding device for warp-knitted fabric, comprising: a workbench 1; two fixed slots are provided at the rear end of the workbench 1; rectangular slots are provided at both ends of the workbench 1, and two threaded slots are provided at the outer ends of the rectangular slots; a support frame 101 is fixedly installed at the middle of the top of the workbench 1, the support frame 101 supports the conveyed warp-knitted fabric, and a limiting frame 102 is installed at both ends of the upper end of the support frame 101. The warp-knitted fabric passes through the bottom of the two limiting frames 102 and is blocked and restricted by the two limiting frames 102, so that the warp-knitted fabric will not deviate during the conveying process and is conveyed smoothly; a fixed base 2 is fixedly installed at the two fixed slots of the workbench 1, and a groove is provided at the upper end of the fixed base 2. The structures on the two fixed bases 2 are identical; symmetrical fixed upright plates 3 are fixedly installed at the rear end of the top of the worktable 1, and the structures on the two fixed upright plates 3 are identical; fixed frames 4 are fixedly installed at the rectangular slots at both ends of the worktable 1, and the rear end of the fixed frames 4 has a slot opening; the front end of the fixed frames 4 has a through support slot; a through electric cylinder 5 is fixedly installed in the middle of the upper end of the fixed frames 4; a bearing plate 501 is fixedly installed at the lower end of the electric cylinder 5, and adjustment ports are respectively opened in the middle of both ends of the bearing plate 501; a fully automatic laser cutting machine 502 is slidably installed at the bottom of the bearing plate 501; symmetrical guide rods 503 are fixedly installed at both ends of the top of the bearing plate 501. The guide rod 503 slides through the guide hole 401. When the support plate 501 slides up and down, the guide rod 503 is restricted by the guide hole 401, and the support plate 501 can only slide up and down to prevent it from shifting or tilting. Parallel track holes 504 are respectively opened at both ends of the support plate 501. Protective gravity plates 6 are slidably installed at both ends of the lower end of the electric cylinder 5. When the electric cylinder 5 pulls the support plate 501 upwards, the support plate 501 will pull the protective gravity plates 6 upwards. The two protective gravity plates 6 are slidably installed in the adjustment ports at both ends of the support plate 501, and stabilizing plates 601 are fixedly installed at the bottom of the two protective gravity plates 6. The electric cylinder 5 is used to push the support plate 501 downwards. 1. With the fully automatic laser cutting machine 502, the protective gravity plates 6 at both ends of the support plate 501 will also move downwards, and the stabilizing plate 601 at the bottom of the protective gravity plate 6 will be placed smoothly on the warp-knitted fabric. The two stabilizing plates 601 are used to press down smoothly on both ends of the warp-knitted fabric, temporarily fixing and restricting the warp-knitted fabric. When the support plate 501 and the fully automatic laser cutting machine 502 continue to move downwards to adjust their positions, the protective gravity plate 6 will move upwards and protrude from the adjustment port of the support plate 501, adjusting the distance between the fully automatic laser cutting machine 502 and the warp-knitted fabric to a suitable level, so that the fully automatic laser cutting machine 502 can cut the warp-knitted fabric below. The two ends of the two protective gravity plates 6 are respectively fixedly installed with track plates 602.The track plate 602 is slidably installed in the track hole 504. When the protective gravity plate 6 slides left and right, the track plate 602 is restricted by the track hole 504, and the protective gravity plate 6 can only slide left and right, preventing the protective gravity plate 6 from shifting or tilting when sliding left and right. The top of the two protective gravity plates 6 are respectively fixedly installed with mutually symmetrical connecting blocks 603, and the side wall of the connecting block 603 is fixedly installed with a bearing ring 604. The outer ring of the bearing ring 604 is fixedly connected to the side wall of the connecting block 603, and the inner ring of the four bearing rings 604 is respectively fixedly installed with threaded rods 605, and the left and right threads are respectively fixedly installed with threaded rods 605. A threaded cylinder 606 is rotatably fitted onto the opposite end of rod 605. Grasping both threaded cylinders 606 and rotating them clockwise simultaneously causes the threaded rods 605 at both ends of the threaded cylinders 606 to pull the protective gravity plates 6 in opposite directions, shortening the distance between the two protective gravity plates 6. Conversely, grasping both threaded cylinders 606 and rotating them counterclockwise causes the threaded rods 605 at both ends of the threaded cylinders 606 to push the protective gravity plates 6 in opposite directions, lengthening the distance between the two protective gravity plates 6. This also adjusts the stabilizing plate 601 at the bottom of the protective gravity plates 6, facilitating the downward pressure of the stabilizing plate 601 on the warp-knitted fabric.

[0022] A synchronous motor 201 is fixedly installed in the groove of the fixed base 2. The warp-knitted fabric is pulled from the right fabric roller 204 and wound onto the left fabric roller 204. At this time, the two synchronous motors 201 are started, causing the rotating shaft to drive the driven shaft 203 and the fabric roller 204 to rotate, pulling the warp-knitted fabric from the right fabric roller 204 and conveying it to the left. A coupling 202 is fixedly connected to the rotating shaft of the synchronous motor 201, and the other end of the coupling 202 is fixedly connected to the driven shaft. Shaft 203, driven shaft 203 passes through shaft hole 301, and fabric roller 204 is installed on the annular side wall of driven shaft 203. Warp-knitted fabric is wound on the right end fabric roller 204. The lower end of fixed vertical plate 3 has a through shaft hole 301. An extension plate 302 is fixedly installed on the front side of the upper end of fixed vertical plate 3. The front end of extension plate 302 has a through round hole. Through anti-detachment holes 303 are respectively opened on both sides of the round hole at the front end of extension plate 302. An electric rod 304 is fixedly installed through the circular hole of the extension plate 302, and an arc-shaped limiting plate 305 is fixedly installed at the lower end of the electric rod 304. The concave surface of the lower end of the limiting plate 305 is attached to the front end of the driven shaft 203. The electric rod 304 is used to push the limiting plate 305 downward. At this time, the side wall of the limiting plate 305 is attached to the side wall of the fabric roller 204, which blocks and restricts the fabric roller 204. When the fabric roller 204 rotates, it will not deviate, thus smoothly outputting the warp-knitted fabric on the fabric roller 204 and preventing the fabric roller 204 from moving forward and falling off during rotation. Two vertically upward anti-detachment rods 306 are fixedly installed at the upper end of the limiting plate 305. The anti-detachment rods 306 slide through the anti-detachment hole 303. When the limiting plate 305 slides up and down, the anti-detachment rods 306 are restricted by the anti-detachment hole 303, and the limiting plate 305 can only slide up and down, preventing the limiting plate 305 from deviating or tilting when sliding up and down.

[0023] The fixed frame 4 has through guide holes 401 at its four corners. Side plates 402 are fixedly installed on the outer side of the lower end of the fixed frame 4. Through bolts are rotatably inserted into both ends of the side plates 402, and these bolts are rotated into the threaded grooves of the workbench 1 to fix and restrict the side plates 402 and the fixed frame 4. The fixed frame 4 will not move when touched, thus stably supporting the electric cylinder 5. A dust collection box 403 is installed at the slot of the fixed frame 4. Symmetrical stabilizing blocks 404 are fixedly installed at the upper and lower ends of the dust collection box 403. Through screws are inserted into the middle of the stabilizing blocks 404, and these screws are rotated into the threaded grooves of the workbench 1. On frame 4, the stabilizing block 404 and the dust collection box 403 are fixed and restricted, so that the dust collection box 403 will not move or fall off when touched. A support beam 405 is fixedly installed at the support slot at the front end of the fixed frame 4, and a blower 406 is fixedly installed in the middle of the support beam 405. The fan blades on the blower 406 correspond to the front end of the dust collection box 403. The fully automatic laser cutting machine 502 completes the cutting of the warp-knitted fabric below. At this time, the two protective gravity plates 6 on the warp-knitted fabric press down and fix it. The blower 406 and the dust collection box 403 are started. The blower 406 blows the debris from the cutting of the warp-knitted fabric backward, and the dust collection box 403 absorbs the blown debris, thereby cleaning the debris on the support frame 101.

[0024] Example 2, based on Example 1, such as Figure 1 and Figure 9 As shown, side plates 402 are fixedly installed on the outer side of the lower end of the fixed frame 4, and through bolts are inserted into both ends of the side plates 402. After removing the side plates 402 and the bolts, the fixed frame 4 is fixedly welded to the workbench 1 to stabilize and restrict the fixed frame 4. This way, the fixed frame 4 will not tilt when touched, avoiding the bolts from loosening after long-term use and failing to stabilize the fixed frame 4, while also saving on parts costs.

[0025] The working principle of this embodiment is as follows: In use, the warp-knitted fabric is first drawn from the right-side fabric roller 204 and wound onto the left-side fabric roller 204. Two synchronous motors 201 are started, driving the driven shaft 203 and fabric roller 204 to rotate synchronously via the coupling 202, achieving smooth conveying of the warp-knitted fabric from right to left. To ensure that the fabric roller 204 does not shift axially during rotation, the electric rod 304 pushes the limiting plate 305 downwards, causing its curved surface to fit tightly against the side wall of the fabric roller 204, thus limiting and fixing the roller body. During conveying, the warp-knitted fabric is supported by the support frame 101 and passes through the two limiting frames 102, thereby preventing fabric shifting during conveying and ensuring the stability of the conveying path. Subsequently, the distance between the two protective gravity plates 6 is adjusted by manually rotating the threaded cylinder 606. The bottom stabilizing plate 601 is designed to accommodate fabrics of varying widths and provides initial pressure on both sides of the warp-knitted fabric. Next, the electric cylinder 5 is activated, pushing the support plate 501 and the fully automatic laser cutter 502 mounted at its bottom downwards. During this process, the protective gravity plate 6 also moves downwards, and the stabilizing plate 601 is smoothly pressed onto the fabric surface, temporarily fixing the warp-knitted fabric. As the support plate 501 continues to move downwards, the protective gravity plate 6 moves upwards relative to it, adjusting the cutting distance between the fully automatic laser cutter 502 and the fabric to achieve precise slitting. During the slitting process, the blower 406 and the dust collection box 403 are activated. The blower 406 blows the cutting debris towards the dust collection box 403, which then collects and absorbs it, effectively keeping the working area clean and preventing impurities from affecting the slitting quality and equipment operation.
