Description

Technical Field

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

[0002] Polyester fabric is a synthetic fabric made of polyester fiber, with polyethylene terephthalate as its main component. It possesses strong wrinkle resistance, good shape retention, and is wear-resistant and heat-resistant, making it widely used in clothing, bags, and industrial products. While its moisture absorption is relatively poor, this can be improved through modification techniques, leading to the development of functional products with flame retardant and antistatic properties.

[0003] In the production and processing of polyester fabrics, cutting equipment is usually required to slit the polyester fabric. However, the existing cutting equipment is difficult to adjust the tension of the fabric during cutting. When the fabric tension changes, wrinkles will appear on the fabric surface, resulting in skewed cutting. Utility Model Content

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A polyester fabric cutting device includes a base plate, a support block fixedly connected to the bottom surface of the base plate, a cutting groove extending through the top surface of the base plate, a fixed frame fixedly connected to the top surface of the base plate, an electric push rod fixedly connected to the inner wall of the fixed frame, a fixed plate fixedly connected to the output end of the electric push rod, a cutting tool fixedly connected to the bottom surface of the fixed plate, a connecting plate fixedly connected to the surface of the fixed plate, a pressing and straightening mechanism disposed inside the connecting plate, an auxiliary component disposed on the top surface of the base plate, a feeding mechanism disposed on the right side of the base plate, and a traction component disposed on the left side of the base plate.

[0006] Preferably, the pressing mechanism consists of a limiting shaft, a fixed frame, a pressure roller, and a spring. The limiting shaft is slidably connected to the inner wall of the connecting plate, the fixed frame is fixedly connected to the bottom end of the limiting shaft, the pressure roller is rotatably connected to the inner wall of the fixed frame, the spring is fixedly connected to the top surface of the fixed frame, and the spring is also fixedly connected to the bottom surface of the connecting plate.

[0007] Preferably, the auxiliary component consists of a support plate and an auxiliary roller, wherein the support plate is fixedly connected to the top surface of the base plate, and the auxiliary roller is rotatably connected to the inner wall of the support plate.

[0008] Preferably, the feeding mechanism consists of a first support frame and a feeding roller, the first support frame being fixedly connected to the right side of the base plate, and the feeding roller being rotatably connected to the inner wall of the first support frame.

[0009] Preferably, the traction assembly consists of a second support frame, a servo motor, a traction roller, and a transmission gear. The second support frame is fixedly connected to the left side of the base plate, the servo motor is fixedly connected to the front of the second support frame, and the output end of the servo motor is rotatably connected to the inner wall of the second support frame. The traction roller is rotatably connected to the inner wall of the second support frame, and the traction roller is fixedly connected to the output end of the servo motor.

[0010] Preferably, the fixing frame is rectangular and made of metal.

[0011] Preferably, there are multiple connecting plates, and all of the multiple connecting plates are located on the surface of the fixed plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This polyester fabric cutting equipment, when the traction component is activated, pulls the fabric to the left, and the electric push rod is activated to push the fixed plate downward. The movement of the fixed plate drives the connecting plate and the pressing mechanism to move downward and contact the fabric, thus pressing the fabric down to the top of the base plate to adjust the moving tension and avoid wrinkles in the fabric. The pressing mechanism's compression and rebound can buffer the downward pressure. The movement of the fixed plate drives the cutting blade to move downward and enter the cutting groove, thus performing the cutting work on the polyester fabric. This achieves the goal of automatically adjusting and sorting the cutting tension of the polyester fabric, avoiding wrinkles caused by changes in the moving tension of the polyester fabric, which would lead to the problem of skewed cutting of the polyester fabric.
