Technical Field

[0001] The present application relates to the field of cloth cutting machines, and in particular to a cloth cutting device. Background Art

[0002] At present, polyester is a synthetic fiber, also known as polyester fiber. It has excellent elasticity and durability, and is often used to make various textiles such as clothing, bedding, sports equipment, etc. Polyester fiber has strong resistance to sunlight and chemicals, and is easy to clean and maintain. Because of its stable performance and not easy to wrinkle and deform, it is deeply loved by consumers. In addition, polyester fiber also has the characteristics of anti-wear and non-sticky hair, making the fabric look neater. Polyester is also often blended with other fibers to improve its properties. For example, blending with cotton and wool can increase breathability and comfort, and blending with nylon can increase wear resistance.

[0003] According to the needs of different products, the cloth needs to be cut into cloth segments of corresponding lengths. The Chinese utility model with application number CN202320903705.9 discloses a novel textile cloth cutting machine, including a bottom box, a support frame welded on the top outer wall of the bottom box, and a fixed rod is arranged inside the support frame, a fixed ring is slidably connected to the outside of the fixed rod, and a cutting wheel is welded to the outside of the fixed ring, a connecting block is integrally formed on the inner wall of one side of the fixed ring, two connecting grooves are opened on the outer wall of one side of the fixed rod, and the connecting block is slidably connected to the inside of the connecting groove, and a top block is welded on the outer wall of one side of the fixed ring; the utility model can install several cutting wheels on the outside of the fixed rod through the fixed rod, so that it is convenient for the staff to adjust the number of cutting wheels when using, and the fixed ring can be moved outside the fixed rod, so that it is convenient for the staff to adjust the position of the cutting wheel when using, and then it can improve the cutting efficiency of the cloth when using, and it is convenient for the staff to adjust the position of the cutting wheel.

[0004] Since polyester fabric has good elasticity, it is easy to deform when cutting it, which will result in low cutting accuracy. Utility Model Content

[0005] In order to improve the cutting accuracy of polyester fabric, the present application provides a fabric cutting device.

[0006] The present application provides a cloth cutting device, which adopts the following technical solution:

[0017] Preferably, the driving assembly includes a rodless cylinder, a bracket and a motor, the rodless cylinder is horizontally arranged, the rodless cylinder is connected to the lifting frame, the bracket is connected to the rodless cylinder, the rodless cylinder is used to move the bracket along the width direction of the fabric, the cutting knife is rotatably connected to the bracket, and the output shaft of the motor is connected to the cutting knife.

[0018] By adopting the above technical solution, after the lifting frame drives the driving assembly to descend, the rodless cylinder drives the cutting knife to rotate while the motor moves the bracket, so that the cutting knife can cut the cloth.

[0019] Preferably, the cloth feeding platform is provided with a long hole, the length direction of the long hole is consistent with the length direction of the fixed plate, the long hole is located between the two fixed plates, and a suction hood is provided at the bottom of the cloth feeding platform, the opening of the suction hood faces the long hole, and the suction hood is connected to a vacuum pump.

[0020] By adopting the above technical solution, the vacuum pump can suck air from the long hole through the suction hood, and the debris generated by the cutting knife when cutting the cloth can enter the suction hood through the long hole, thereby preventing the debris from floating in the air as much as possible.

[0025] 2. The fixing plate can press the fabric on the top of the support strip through the first rubber strip. The first rubber strip can increase the friction between the fixing plate and the fabric, and can avoid the fabric from slipping between the fixing plate and the support strip when the cutting knife cuts the fabric. This can improve the stability of the fabric during cutting and the cutting accuracy of polyester fabric.

[0026] 3. After the fabric is cut, the fixed plate separates from the fabric after rising, and the filter screen can block the fabric to prevent the fabric from being sucked into the long holes as much as possible. The debris generated by the cutting knife when cutting the fabric can still enter the suction hood through the filter screen. BRIEF DESCRIPTION OF THE DRAWINGS
