Description

Technical Field

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

[0002] An existing fabric processing cutting device consists of a robust frame structure to ensure stability during the cutting process. Equipped with sharp cutting blades, it can quickly and accurately cut various fabrics. A conveyor system smoothly transports the fabric to the cutting area, ensuring continuous cutting. Some advanced devices also feature automatic adjustment functions, automatically adjusting the cutting force and speed according to the fabric thickness and material. In terms of operation, a user-friendly control panel is designed for easy parameter setting and monitoring of the cutting process. Furthermore, some cutting devices consider environmental factors by incorporating a dust collection system to effectively collect debris and dust generated during cutting. This fabric processing cutting device significantly improves production efficiency, reduces human error, and brings higher quality standards and more reliable production methods to the fabric processing industry.

[0003] A search revealed Chinese patent publication number CN221218245U, which discloses a knitted fabric cutting device. The device includes a worktable, a first support block on the upper left side of the worktable, a fixed block at the rear end of the first support block, a roll roller rotatably connected to the fixed block, a support frame at the upper end of the worktable, and a cutting assembly at the upper end of the worktable. The cutting assembly includes a cylinder mounted on the upper end of the support frame, a connecting frame fixedly connected to the bottom end of the cylinder's output rod, a protective cover at the front end of the connecting frame, a first motor inside the protective cover, a rotating shaft fixedly connected to the rear end of the first motor's output shaft, a cutting blade in the middle of the rotating shaft, and second support blocks at the front and rear ends of both sides of the support frame. This invention not only accelerates the cutting process of knitted fabrics but also avoids deviations that could affect the processing quality of the knitted fabrics, thus improving the cutting efficiency. However, different fabrics require different cutting tools. In actual use, because the cutting tools are threadedly connected to the cutting equipment via a fixed block, changing them requires a significant amount of time, leading to reduced work efficiency. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a cutting device for fabric processing, which aims to improve the problem in the prior art that requires a lot of time to change different cutting tools for different fabrics.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a fabric processing cutting device, comprising a U-shaped base, a U-shaped block slidably connected to the top of the U-shaped base, a notch formed at the top of the U-shaped block, a rack fixedly connected to the left side of the top of the U-shaped block, a shaped moving block slidably connected to the inner wall of the notch, a servo motor fixedly connected to the top of the shaped moving block, a gear fixedly connected to the output end of the servo motor, the gear meshing with the rack, a telescopic rotating assembly fixedly connected to the bottom of the shaped moving block, and a rotating plate fixedly connected to the bottom of the telescopic rotating assembly. A DC motor is fixedly connected to the rear side of the rotating plate. The output end of the DC motor passes through the rotating plate and is fixedly connected to a rotating column. Multiple L-shaped columns are fixedly connected to the outer side of the rotating column. A hollow column is fixedly connected to the front side of the rotating column. Triangular blocks are slidably connected to the upper and lower sides of the inner wall of the hollow column. A spring is fixedly connected to the adjacent side of two triangular blocks. A cutting blade is provided on the outer side of the hollow column. A fixing ring is provided on the front side of the hollow column. A conveyor belt is provided on the top of the U-shaped base. A linkage mechanism is provided on the bottom of the U-shaped block. The linkage mechanism is used to move together with the fabric during cutting.

[0006] As a further description of the above technical solution:

[0007] Through the above technical solution: the fabric is placed on a conveyor belt and moves. By starting the servo motor, the gear one can be driven to rotate, which in turn moves the servo motor and the irregularly shaped moving block above it through meshing with the rack one. Then, the position of the rotating plate can be moved by the telescopic rotating component. By starting the DC motor, the rotating column can be driven to rotate, which in turn drives the outer L-shaped column to rotate, thereby driving the outer cutting blade to rotate. When the cutting blade needs to be replaced, simply press the triangular latch to release the engagement between the triangular latch and the fixed ring. Then, remove the fixed ring and the cutting blade, insert the replacement cutting blade along the hollow column, and then insert the fixed ring. Release the triangular latch, and the fixed ring and the cutting blade will be firmly fixed by the action of the spring one to prevent loosening during the cutting process.

[0008] The linkage mechanism includes multiple springs, which are respectively fixedly connected to the front and rear sides of the inner wall of the U-shaped block. A moving plate is fixedly connected to the bottom of the multiple springs, and a cutting base plate is fixedly connected to the bottom of the moving plate.

A hydraulic rod is fixedly connected to the right side of the fixed plate, and one end of two hydraulic rods is fixedly connected to the U-shaped block.

[0009] Through the above technical solution: when the cutting blade falls to cut the fabric, it will cause the cutting base plate to come into contact with the conveyor belt. At this time, the limiting block at the bottom of the cutting base plate will engage with the limiting groove above the conveyor belt, so that the cutting base plate moves together with the conveyor belt, and at the same time, it will drive the U-shaped block to move together, so that there will be no deviation when cutting the fabric. After the cutting is completed, the cutting base plate will be reset under the action of the second spring, thereby releasing the limiting block from the limiting groove, and resetting under the action of the hydraulic rod, which is convenient for the next cutting.

[0010] As a further description of the above technical solution:

[0011] The telescopic rotating assembly includes a cylinder, which is fixedly connected to the bottom of the irregularly shaped moving block. One end of the cylinder is rotatably connected to a gear. A fixing plate is fixedly connected to the bottom left side of the irregularly shaped moving block, and an electric telescopic rod is fixedly connected to the bottom right side of the fixing plate. A rack is fixedly connected to one side of the electric telescopic rod, and the rack meshes with the gear.

[0012] The above technical solution allows the cylinder to move gear two up and down, and the electric telescopic rod to move the rack, thereby causing gear two to rotate.

[0013] As a further description of the above technical solution:

[0014] A fixing block is fixedly connected to the front side of the U-shaped block, and a hazard sign block is fixedly connected to the front side of the fixing block.

[0015] The above technical solution allows hazard warning blocks to remind operators to pay attention to safety.

[0019] As a further description of the above technical solution:

[0020] A lighting lamp is fixedly connected to the front inner wall of the U-shaped block, and an infrared sensor is fixedly connected to the bottom of the irregularly shaped moving block.

[0021] The above technical solution allows for additional lighting through a lamp and precise control of the cutting size through an infrared sensor.

[0022] As a further description of the above technical solution:

[0023] The top front and rear sides of the U-shaped base are fixedly connected with slide rails, which are slidably connected to the U-shaped block. The inner wall of the recess is provided with a sliding groove, which is slidably connected to the irregularly shaped moving block.

[0024] The above technical solution allows for the sliding of U-shaped blocks via a slide rail and facilitates the movement of irregularly shaped moving blocks via a slide groove.

[0025] As a further description of the above technical solution:

[0026] A support plate is fixedly connected to the bottom of the rotating plate, and auxiliary wheels are rotatably connected to the front and rear sides of the support plate.

[0027] The above technical solution allows the moving plate to move effectively using the support plate and auxiliary wheels.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, by starting the servo motor to rotate gear one, it meshes with rack one, driving the irregular moving block to move. The telescopic rotating component then adjusts the position of the rotating plate. After the DC motor starts, the rotating column and the outer L-shaped column rotate accordingly, driving the cutting blade to rotate. When replacing the cutting blade, press the triangular locking block to release the fixing ring, remove and replace the cutting blade, reinstall the fixing ring, loosen the triangular locking block, and spring one ensures that the fixing ring and the cutting blade are firmly engaged, which can quickly complete the replacement.

[0030] 2. In this utility model, when the cutting blade descends to cut the fabric, it pushes the cutting base plate to contact the conveyor belt. The limiting block of the cutting base plate engages with the limiting groove above the conveyor belt to ensure that the base plate and the conveyor belt move synchronously. At the same time, it drives the U-shaped block to ensure accurate cutting. After the cutting is completed, the spring resets the cutting base plate and releases the engagement between the limiting block and the groove. The hydraulic rod assists in the reset, which can facilitate the correction of errors caused by movement during cutting. Attached Figure Description
