Description

Technical Field

[0001] This utility model relates to the field of nylon yarn processing technology, and in particular to a rapid cutting device for high-strength, wrinkle-resistant nylon yarn. Background Technology

[0002] Nylon yarn is a type of textile fabric, which comes in various types such as monofilament, plied yarn, and specialty yarn. Compared to the luster of silk, nylon yarn fabrics have a poorer luster, giving the impression of being coated with a layer of wax. When rubbed back and forth by hand, you can feel the friction between the fabrics. However, nylon yarn has a beautiful elasticity.

[0003] Existing nylon filament cutting devices have some drawbacks: due to the soft and easily deformable nature of nylon filaments, some filaments may not be completely cut during the cutting process due to pressure slippage or incomplete blade closure, resulting in incomplete cutting and residual filament adhesion. This not only affects cutting efficiency and finished product quality but also requires secondary manual processing, reducing the practicality and production efficiency of the device. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a rapid cutting device for high-strength, wrinkle-resistant nylon yarn.

[0005] This utility model provides a rapid cutting device for wrinkle-resistant, high-strength nylon yarn, comprising:

[0006] Mounting plate, on which a bracket is fixedly mounted, and a guide rod is fixedly mounted between the mounting plate and the bracket;

[0007] A cutting assembly includes a cylinder, a lifting plate, a mounting block, and a cutting blade. The cylinder is fixedly mounted on a bracket, and a roller is mounted on the output end of the cylinder. A support rod is fixedly mounted on the mounting block, and a limit block is fixedly mounted on the top of the support rod. The support rod slides through the lifting plate. A spring is fixedly mounted on the mounting block, and the other end of the spring is fixedly mounted on the bottom of the lifting plate. The cutting blade is located at the bottom of the mounting block.

[0008] A fixing component is provided for fixing the cutting blade. The fixing component includes a pressure plate and a threaded rod. The bottom of the mounting block is provided with a mounting groove. One end of the threaded rod is rotatably connected to one side of the pressure plate. The threaded rod passes through one side of the mounting block and is threadedly connected to it. A rotating block is fixedly provided at the outer end of the threaded rod.

[0009] Furthermore, a positioning post is fixedly provided on one side of the pressure plate, and a positioning hole is provided through the cutting blade.

[0010] Furthermore, the output end of the cylinder is movably disposed through the bracket, and the roller is abutted against the lifting plate.

[0011] Furthermore, the guide rod is inclined and slides through the lifting plate.

[0012] Furthermore, the mounting plate is provided with a placement groove, and a cutting board is placed in the placement groove. Notch grooves are provided on both sides of the placement groove.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. A cutting component is installed. The lifting plate is pushed diagonally downward by a cylinder and rollers. When the cutting blade comes into contact with the cutting board, the cutting blade is pushed to one side by the support rod, simulating the diagonal cutting trajectory when cutting vegetables manually. This diagonal cutting of nylon filaments ensures that the nylon filaments are completely cut, avoiding the problem of residual and sticky filaments caused by incomplete cutting, thus improving the quality of finished products and production efficiency.

[0015] 2. A fixing assembly is provided. First, rotate the threaded rod outward to separate the pressure plate from the cutting blade and the positioning pin from the positioning hole, thus removing the cutting blade. Then, rotate the threaded rod inward by rotating the block to insert the positioning pin into the positioning hole, and use the pressure plate to press the cutting blade against the hole, thus fixing the cutting blade. The operation is simple and convenient, facilitating the replacement or maintenance of the cutting blade.

[0016] In summary, this utility model is equipped with a cutting component that can cut nylon yarn at an angle, avoiding the problem of yarn residue and adhesion caused by incomplete cutting, thus improving the quality of finished products and production efficiency. It is also equipped with a fixing component that allows for easy disassembly and assembly of the cutting blade, facilitating replacement or maintenance and increasing its practicality.

Detailed Implementation

[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0022] like Figures 1-3 As shown in the figure, this utility model embodiment proposes a rapid cutting device for wrinkle-resistant high-strength nylon yarn, including:

[0023] Mounting plate 1, with bracket 2 fixedly mounted on it. Mounting plate 1 has a placement groove 17, within which a cutting board 18 is placed. The placement groove 17 is used to hold the cutting board 18. The cutting board 18 is used in conjunction with the cutting blade 6 to cut nylon yarn; the cutting board 18 is made of a wear-resistant flexible material (ultra-high molecular weight polyethylene) to ensure its lifespan. Notches 19 are provided on both sides of the placement groove 17 to facilitate the removal of the cutting board 18 from the placement groove 17.

[0024] The cutting assembly includes a cylinder 3, a lifting plate 4, a mounting block 5, and a cutting blade 6. The cylinder 3 is fixedly mounted on the bracket 2, and the output end of the cylinder 3 is movably disposed through the bracket 2. A roller 10 is installed on the output end of the cylinder 3, so that the cylinder 3 can drive the roller 10 to move. The roller 10 is disposed against the lifting plate 4, and the roller 10 can reduce the friction between the cylinder 3 and the lifting plate 4, so that the lifting plate 4 can move more smoothly along the guide rod 9.

[0025] Two guide rods 9 are fixedly installed between the mounting plate 1 and the bracket 2. The two guide rods 9 are parallel and inclined, and slide through the lifting plate 4. The guide rods 9 guide the lifting plate 4. A support rod 7 is fixedly installed on the mounting block 5. A limit block is fixedly installed on the top of the support rod 7. The support rod 7 slides through the lifting plate 4 and guides and supports the mounting block 5. A spring 8 is fixedly installed on the mounting block 5. The other end of the spring 8 is fixedly installed at the bottom of the lifting plate 4, so that the mounting block 5 can be elastically connected to the lifting plate 4 through the spring 8. A cutting blade 6 is located at the bottom of the mounting block 5.

[0026] A fixing assembly is used to fix the cutting blade 6. The fixing assembly includes a pressure plate 13 and a threaded rod 15. The bottom of the mounting block 5 is provided with a mounting groove 11, and the cutting blade 6 is placed in the mounting groove 11. A positioning hole 12 is provided through the cutting blade 6. A positioning post 14 is fixedly provided on one side of the pressure plate 13 and is inserted into the positioning hole 12. The positioning post 14 is used to position the cutting blade 6. One end of the threaded rod 15 is rotatably connected to one side of the pressure plate 13. The threaded rod 15 passes through one side of the mounting block 5 and is threadedly connected to it. A rotating block 16 is fixedly provided on the outer end of the threaded rod 15. The rotating block 16 is used to rotate the threaded rod 15.

[0027] The detailed working process of this utility model is as follows:

[0028] 1. In use, the cylinder 3 drives the roller 10 to move downward, and the roller 10 presses the lifting plate 4 downward. The lifting plate 4 will move diagonally downward along the guide rod 9 to cut the nylon filament. When the cutting blade 6 comes into contact with the cutting board 18, the lifting plate 4 continues to move diagonally downward, compressing the spring 8, and then the support rod 7 pushes the cutting blade 6 to one side, simulating the diagonal cutting trajectory when cutting vegetables, to diagonally cut the nylon filament, thus ensuring that the nylon filament is completely cut.

[0029] 2. When replacing, first rotate the threaded rod 15 outward by rotating the rotating block 16 to separate the pressure plate 13 from the cutting blade 6 and the positioning pin 14 from the positioning hole 12, so that the cutting blade 6 can be removed; put the cutting blade 6 into the mounting groove 11, then rotate the threaded rod 15 inward by rotating the rotating block 16 and insert the positioning pin 14 into the positioning hole 12. Finally, use the pressure plate 13 to press the cutting blade 6 firmly.
