Description

Technical Field

[0001] This utility model belongs to the field of fiber equipment, and in particular relates to a laser cutting device for ultrafine fiber wiping cloth. Background Technology

[0002] In the fabric manufacturing process, large pieces of fabric need to be cut. Laser cutting involves focusing a laser beam emitted from a laser source into a high-power-density beam through an optical path system. This laser beam irradiates the surface of the fabric, causing it to reach its melting or boiling point. Simultaneously, high-pressure gas coaxial with the beam blows away the molten or vaporized metal. As the relative position of the beam and the workpiece moves, a slit is formed in the material, achieving the cutting purpose. Currently, laser cutting devices for fabric typically place the fabric directly flat on the cutting table, lacking the function of straightening the fabric. This easily leads to unevenness and wrinkles in the fabric, affecting the quality of the cut.

[0003] For example, Chinese patent literature discloses a laser cutting device for fabric used in garment manufacturing [patent application number: CN202411784933.4], which includes: a frame, in which two conveyor rollers are symmetrically and rotatably installed, and a conveyor belt is sleeved between the two conveyor rollers, and a drive motor for driving one of the conveyor rollers is fixedly installed on the outside of the frame; a lifting plate, which is slidably sleeved on the frame, and an electric push rod for driving the lifting plate is fixedly installed inside the frame. Utility Model Content

[0004] The purpose of this invention is to address the above-mentioned problems by providing a laser cutting device for microfiber wiping cloths.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A laser cutting device for microfiber wiping cloth includes a machine tool. The machine tool has a take-up device and a take-up drum at each end. The machine tool is provided with a cloth feeding table. A laser cutting table is provided on the cloth feeding table. A laser cutting emitter is laterally moved on the side of the laser cutting table near the cloth feeding table. Several cloth clamping structures are provided on both sides of the cloth feeding table. The cloth clamping structures are moved on the machine tool by a transport moving structure.

[0007] In the aforementioned microfiber wiping cloth laser cutting device, each side of the cloth-laying table is provided with at least four cloth-clamping structures. When the wiping cloth covers the entire cloth-laying table, two of the cloth-clamping structures are located at both ends of the cloth-laying table, and the other two cloth-clamping structures are located on both sides of the laser cutting table.

[0008] In the aforementioned microfiber wiping cloth laser cutting device, the cloth clamping structure includes a cloth clamping block connected to a transport and moving structure. Two cloth clamping plates are movably connected inside the cloth clamping block and placed opposite each other. The cloth clamping block is also provided with a moving block that can move along the vertical direction. The cloth clamping plates are connected to the moving block, and the moving block is screwed to the output shaft of a rotating motor provided on the cloth clamping block.

[0009] In the aforementioned microfiber wiping cloth laser cutting device, a connecting plate is provided between the clamping plate and the moving block. One end of the connecting plate is fixedly connected to the clamping plate, and the other end extends into the moving block and is slidably connected to the moving block laterally. The connecting plate is also slidably connected to an inclined rod fixed inside the clamping block and placed at an angle. When the two clamping plates move closer to each other, the connecting plate will move the clamping plates away from the moving block.

[0010] In the aforementioned microfiber wiping cloth laser cutting device, power interface plates are provided at both ends of the machine tool. When the cloth clamping block moves to the end of the machine tool near the output drum, the rotating motor is connected to the power interface plate.

[0011] In the aforementioned microfiber wiping cloth laser cutting device, the transport and movement structure includes a transport and movement circulation loop formed by a conveyor belt, the conveyor belt is connected to a power source, and the cloth clamping block is connected to the conveyor belt.

[0012] In the aforementioned microfiber wiping cloth laser cutting device, the transport and movement structure further includes a transport support ring whose shape corresponds to and is placed parallel to the transport and movement circulation ring. The conveyor belt is provided with a plurality of driven shafts, the driven shafts extend through the transport support ring, and the transport support ring passes through the driven shafts and is slidably connected to the driven shafts. The driven shafts are connected to the cloth clamping block.

[0013] In the aforementioned microfiber wiping cloth laser cutting device, the cloth clamping block is connected to two driven shafts. The side of the cloth clamping block connected to the driven shafts is recessed with an arc-shaped abutment. One driven shaft is rotatably connected to the cloth clamping block, and the other driven shaft extends into the arc-shaped abutment. When the driven shaft abuts against the apex of the arc-shaped abutment, the cloth clamping block is in the working position.

[0014] In the aforementioned microfiber wiping cloth laser cutting device, the machine tool is also provided with a clamping shaft on the side near the output drum, and the clamping shaft is connected to the lifting structure.

[0015] In the aforementioned microfiber wiping cloth laser cutting device, smoke inlets are provided on both sides of the laser cutting table.

[0016] Compared with existing technologies, the advantages of this utility model are:

[0017] 1. Several clamping structures can clamp the wiping cloth on the cloth-laying table and move the wiping cloth with the transport and moving structure. When the wiping cloth is spread on the cloth-laying table, it is in a tensile state under the action of several clamping structures, which makes the cutting effect better.

[0018] 2. The clamping plate is positioned on the outside of the wiping cloth in the initial state before clamping it, to prevent the wiping cloth from being blocked by the clamping plate and folding up when it moves.

[0019] 3. Since the fabric clamping block needs to move continuously during operation, it is inconvenient to connect to the power supply via wires. Furthermore, the fabric clamping plate only works to clamp or release the fabric when it is located at both ends of the machine tool. Therefore, power interface plates are provided at both ends of the machine tool to provide power and optimize the distribution of wires. Attached Figure Description

Detailed Implementation

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0026] This utility model provides a laser cutting device for microfiber wiping cloths, combined with... Figure 1-4 As shown, the machine tool includes a machine tool 10, which has a take-up device and a take-out drum at each end. The machine tool 10 is provided with a fabric feeding table 11, on which a laser cutting table 12 is provided. A laser cutting emitter is laterally moved on the side of the laser cutting table 12 near the fabric feeding table 11. Several fabric clamping structures 13 are provided on both sides of the fabric feeding table 11. The several fabric clamping structures 13 move on the machine tool 10 through a transport moving structure 14.

[0027] In this embodiment, the rotating roll unfolds the wiping cloth and moves it onto the cloth-laying platform 11. Several cloth-clamping structures 13 can clamp the wiping cloth on the cloth-laying platform 11 and move it along with the cloth under the operation of the transport and moving structure 14. After the wiping cloth covers the cloth-laying platform 11, it is in a taut state under the operation of the several cloth-clamping structures 13. Then, the taut wiping cloth is cut by the laser cutting emitter. The front end of the cut wiping cloth is collected by the cloth-collecting device. The rear end of the cut wiping cloth continues to be laid on the cloth-laying platform 11 under the operation of the cloth-clamping structure 13 and the transport and moving structure 14 and then undergoes the cutting step.

[0028] Each side of the cloth-laying table 11 is provided with at least four cloth-clamping structures 13. When the wiping cloth is fully laid on the cloth-laying table 11, two of the cloth-clamping structures 13 are located at both ends of the cloth-laying table 11, and the other two cloth-clamping structures 13 are located on both sides of the laser cutting table 12.

[0029] In this embodiment, when the end of the wiping cloth moves to the cloth placement table 11, the first clamping structure 13 clamps the wiping cloth and moves forward under the drive of the transport moving structure 14. Then, the second clamping structure 13 clamps the wiping cloth and moves forward under the drive of the transport moving structure 14. The above steps are repeated until all four clamping structures 13 clamp the wiping cloth. After cutting, both ends of the wiping cloth after being cut are clamped by two clamping structures 13. The front part of the wiping cloth is collected by the cloth collection device under the drive of the two clamping structures 13 and the transport moving structure 14. The rear part of the wiping cloth moves forward to the next cutting position under the drive of the other clamping structures 13 and the transport moving structure 14.

[0030] The fabric clamping structure 13 includes a fabric clamping block 15 connected to the transport moving structure 14. Two fabric clamping plates 16 are movably connected inside the fabric clamping block 15 and placed opposite each other. The fabric clamping block 15 is also provided with a moving block 17 that can move along the vertical direction. The fabric clamping plates 16 are connected to the moving block 17. The moving block 17 is screwed to the output shaft of the rotating motor 18 provided on the fabric clamping block 15.

[0031] In this embodiment, during the process of the cloth clamping structure 13 clamping the wiping cloth, the rotating motor 18 works to cause the moving block 17 to drive the two cloth clamping plates 16 to move closer to each other, thereby clamping the wiping cloth.

[0032] A connecting plate 19 is provided between the fabric clamping plate 16 and the moving block 17. One end of the connecting plate 19 is fixedly connected to the fabric clamping plate 16, and the other end extends into the moving block 17 and is slidably connected to the moving block 17. The connecting plate 19 is also slidably connected to an inclined rod 21 fixed in the fabric clamping block 15 and placed at an angle. When the two fabric clamping plates 16 move closer to each other, the connecting plate 19 will move the fabric clamping plates 16 away from the moving block 17.

[0033] In this embodiment, the clamping plate 16 is located outside the wiping cloth in the initial state before clamping the wiping cloth, to prevent the wiping cloth from being blocked by the clamping plate 16 and folding up when moving. During the clamping process, the rotating motor 18 works to make the moving block 17 drive the two clamping plates 16 to move closer to each other. During this process, due to the guiding effect of the inclined rod 21, the two moving blocks 17 move towards the outside of the clamping block 15 while moving closer to each other, so that the wiping cloth enters between the two clamping plates 16 and is finally clamped by the two clamping plates 16.

[0034] The machine tool 10 is provided with power interface pieces at both ends. When the clamping block 15 moves to the end of the machine tool 10 close to the output drum, the rotating motor 18 is connected to the power interface piece.

[0035] In this embodiment, since the clamping block 15 needs to move continuously during operation, it is inconvenient to connect to the power supply via wires. Furthermore, the clamping plate 16 only works to clamp or release the fabric when it is located at both ends of the machine tool 10. Therefore, power interface plates are provided at both ends of the machine tool 10 to provide power, thus optimizing the distribution of wires.

[0036] The transport and movement structure 14 includes a transport and movement loop formed by a conveyor belt 22, the conveyor belt 22 is connected to a power source, and the fabric clamping block 15 is connected to the conveyor belt 22.

[0037] The transport moving structure 14 also includes a transport support ring 23 whose shape corresponds to and is placed parallel to the transport moving loop. A plurality of driven shafts 24 are provided on the conveyor belt 22. The driven shafts 24 extend through the transport support ring 23, and the transport support ring 23 passes through the driven shafts 24 and is slidably connected to the driven shafts 24. The driven shafts 24 are connected to the fabric clamping block 15.

[0038] The fabric clamping block 15 is connected to two driven shafts 24. The side of the fabric clamping block 15 connected to the driven shafts 24 is recessed with an arc-shaped abutment ring 25. One driven shaft 24 is rotatably connected to the fabric clamping block 15, and the other driven shaft 24 extends into the arc-shaped abutment ring 25. When the driven shaft 24 abuts against the apex of the arc-shaped abutment ring 25, the fabric clamping block 15 is in the working position.

[0039] In this embodiment, since the clamping block 15 is large in size and the movement path has an arc, the problem is overcome by the arc-shaped abutment 25 to prevent jamming.

[0040] The machine tool 10 is also provided with a clamping shaft 26 on the side near the output drum, and the clamping shaft 26 is connected to the lifting structure.

[0041] In this embodiment, the wiping cloth passes through the lower surface of the pressing shaft 26. After the first clamping structure 13 clamps the cloth, when several remaining clamping structures 13 are needed to clamp the cloth, the pressing shaft 26 moves downward under the action of the lifting structure to tension the wiping cloth.

[0042] The laser cutting stage 12 is provided with smoke inlets 27 on both sides.

Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0044] Although this article frequently uses terms such as machine tool 10, fabric feeding table 11, laser cutting table 12, fabric clamping structure 13, transport and moving structure 14, fabric clamping block 15, fabric clamping plate 16, moving block 17, rotating motor 18, connecting plate 19, diagonal bar 21, conveyor belt 22, conveyor support ring 23, driven shaft 24, arc abutment ring 25, pressing shaft 26, and smoke inlet 27, these terms are used merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any kind of additional limitation would be contrary to the spirit of this utility model.
