Description

Technical Field

[0001] The utility model relates to the technical field of non-woven fabric cutting, in particular to a non-woven fabric cutting device. Background Art

[0002] Non-woven fabrics are made of directional or random fibers. They are a new generation of environmentally friendly materials with the characteristics of moisture-proof, breathable, flexible, light, non-combustible, easy to decompose, non-toxic and non-irritating, rich in colors, low price, and recyclable. For example, polypropylene (pp material) pellets are often used as raw materials, and are produced by a continuous one-step process of high-temperature melting, spinning, laying, hot pressing and winding. It is called cloth because it has the appearance and certain properties of cloth.

[0003] It is not made of yarns interwoven and knitted together, but the fibers are directly bonded together by physical methods, so when you take the sticky scales in your clothes, you will find that you cannot pull out the threads one by one. Nonwoven fabrics break through the traditional textile principles and have the characteristics of short process flow, fast production rate, high output, low cost, wide application, and multiple sources of raw materials.

[0004] In the production and packaging process of non-woven fabrics, the non-woven fabrics are cut according to different needs. Manual cutting is time-consuming and labor-intensive. At the same time, there will be length errors when cutting the same batch of fabrics. Even if there are cutting devices, when it is necessary to cut fabrics of different lengths, the cutting device needs to be replaced. Although this saves time and effort than manual work, the cost is too high and is not suitable for large-scale use. At the same time, when cutting, the cutting edges of the fabrics will produce debris and wool, which can easily cause pollution to the working environment and harm the human respiratory tract.

Both sides of the top of the cutting table 1 are provided with a non-woven fabric driving mechanism. The non-woven fabric driving mechanism comprises a driving pulley 8 and a driven pulley 9. The driving pulley 8 and the driven pulley 9 are sleeved with a synchronous belt 10 on the outer side. A plurality of sockets 11 are evenly distributed on the outer side of the synchronous belt 10. The sockets 11 are connected with clamping mechanisms through connectors 12. The clamping mechanisms are arranged in groups of two.

[0028] The driving pulley 8 rotates to drive the synchronous belt 10 to move, thereby driving the clamping mechanism to move. The clamping mechanism can clamp the two side edges of the non-woven fabric, so that the non-woven fabric can move with the synchronous belt 10, and the cut part of the non-woven fabric can be sent to the bottom of the cutting blade 4, so that the cutting blade 4 can be driven by the cutting cylinder 3 to cut the non-woven fabric. The cutting position is located between the clamping mechanisms in groups of two. After the cutting is completed, the clamping mechanism located at the rear of the moving direction continues to hold, and the clamping mechanism located in front of the moving direction is released, so that the cut part can be separated, and the remaining non-woven fabric that needs to be cut continues to move with the synchronous belt 10, and then continues the next cutting, and cooperates with the unwinding device to cut, which is more efficient and convenient.

[0029] Among them, a first rotating motor 19 is fixed to the bottom end of the cutting table 1, and two first bevel gears 20 are fixed to the output shaft of the first rotating motor 19. The two first bevel gears 20 are symmetrically arranged up and down, and second bevel gears 23 are fixed to the mounting shafts of the two driving pulleys 8.

The two synchronous belts 10 move in the same direction on the sides close to each other, thereby driving the non-woven fabric to move.

[0031] The top of the cutting table 1 is provided with a cutting matching seat 6 just below the cutting blade 4, and the top of the cutting matching seat 6 is provided with a notch 7 that matches with the cutting blade 4;

[0034] The guiding function of the guide rod 5 can improve the stability of the lifting and lowering movement of the cutting blade 4.

[0036] The second rotary motor 14 can drive the bidirectional threaded rod 15 to rotate, thereby driving the two lifting blocks 16 to move closer to or farther away from each other, so that the non-woven fabric can be clamped and released by the approach and distance of the two clamping plates 17 .

[0037] A rubber pad 18 is fixed to one side of the two clamping plates 17 that are close to each other, and a groove is provided on the rubber pad 18 for increasing friction.
