Description

Technical Field

[0001] This utility model relates to the field of fabric opening machines for leather production and processing, and more specifically, to a fabric opening machine for leather production and processing. Background Technology

[0002] The process of loosening and removing impurities from compressed, tangled fiber raw materials is crucial for spinning. Various fiber raw materials used in spinning, such as raw cotton, wool, short chemical fibers, cotton, linen, polyester, and scrap fabric, are mostly transported to textile mills in bundled form. To produce high-quality fine yarn, the raw materials must first be loosened, various impurities removed, and the mixture homogeneously mixed. The quality of fiber opening significantly impacts the quality of semi-finished products and yarn, as well as material savings. Currently, most fabric opening machines used in leather production employ a method where leather is laid on a conveyor belt and opened by cutters; however, an automatic fabric cutting machine is required. As per existing technology, such as the patent announcement number CN215366505U, this utility model relates to the field of leather production and processing technology, and discloses a leather cutting machine for leather production and processing. The machine includes a main frame, with a discharge port on the upper front of the main frame. Limiting frames are slidably fitted onto both sides of the discharge port. A cutting table is fixedly connected to the middle of the main frame, and a lifting motor is fixedly connected to the top left side of the cutting table. The output shaft of the lifting motor is slidably fitted onto a sliding table, and a servo motor is installed on the top of the sliding table. This leather cutting machine, through the positioning and limiting frames at the inlet and outlet, ensures that the leather does not tilt during conveyor belt transport and moves in a straight line. After the cutting tool cuts the leather, it passes through the discharge port, where the limiting frames gather and transport the cut leather out. This ensures that the leather does not deviate from the conveyor belt during the entire cutting process and is not blocked at the outlet, thus improving the practicality of the device. In the aforementioned patent, the leather fabric is squeezed by setting extrusion components at the four corners. However, a problem arises during processing: the leather is not easily fixed and positioned when squeezed at the corners. Also, different leathers are of different sizes. If the leather cannot be fully laid on the surface, it cannot be squeezed and positioned. Furthermore, when the leather is initially unfolded, the wrinkles are uneven and it cannot be fully unfolded and flattened for positioning. Utility Model Content

[0003] To address the problems existing in the prior art, the purpose of this utility model is to provide a fabric opening machine for leather production and processing. By adopting a moving strip structure that can synchronously shrink and expand, it can drive the positioning strip of the bottom shell to slide, and can press and flatten the leather surface to avoid wrinkles. Its pressing and positioning position is automatically adjusted, and it can accurately position leather of different sizes.

[0004] To solve the above problems, the present invention adopts the following technical solution.

[0005] A fabric cutting machine for leather production and processing includes a fabric cutting machine body. A conveyor belt is installed on the inner surface of the fabric cutting machine body, and a cutting assembly is installed on the outer surface of the fabric cutting machine body. A support base is fixedly connected to the outer surface of the fabric cutting machine body, and a motor is fixedly connected to the outer surface of the support base.

[0007] Furthermore, the lower surfaces of the first and second moving bars are provided with convex sliders, and the upper surface of the fabric cutting machine body is provided with convex slide rails. The outer surfaces of the convex sliders of the first and second moving bars are slidably connected to the inner surface of the convex slide rails of the fabric cutting machine body.

[0008] Furthermore, the convex sliders are distributed at the left and right ends of the lower surfaces of the first and second moving strips, and the convex slide rails are distributed on the left and right sides of the upper end of the fabric cutting machine body.

[0009] Furthermore, the motor is a reversible motor.

[0011] Furthermore, the surfaces of the first and second moving bars are provided with three sets of insertion slots, and the outer surface of the positioning rod slides through the inner surface of the insertion slots of the first and second moving bars.

[0012] Compared with existing technologies, the advantages of this utility model are: (1) By adopting a moving strip structure that can be synchronously contracted and expanded, the positioning strip of the bottom shell can be driven to slide, and can be pressed on the leather surface to flatten it and avoid wrinkles. Its pressing positioning position is automatically adjusted, and different sizes of leather can be accurately positioned. Attached Figure Description

Three sets of positioning rods 9 are fixedly connected to the upper surface of the positioning strip 10. A support base 2 11 is fixedly connected to the end face of the positioning rod 9 at the middle end of the positioning strip 10. An electric cylinder 12 is fixedly connected to the lower surface of the support base 2 11. The end face of the push rod of the electric cylinder 12 is fixedly connected to the upper surface of the first moving strip 7 and the second moving strip 8. In use, the up and down movement of the positioning strip 10 can be adjusted by raising and lowering the electric cylinder 12, which can squeeze and release the leather fabric. The lower surfaces of the first moving bar 7 and the second moving bar 8 are provided with convex sliders 78, and the upper surface of the fabric cutting machine body 1 is provided with convex slide rails 780. The outer surfaces of the convex sliders 78 of the first moving bar 7 and the second moving bar 8 are slidably connected to the inner surface of the convex slide rails 780 of the fabric cutting machine body 1. The convex sliders 78 are distributed at the left and right ends of the lower surfaces of the first moving bar 7 and the second moving bar 8, and the convex slide rails 780 are distributed on the left and right sides of the upper end of the fabric cutting machine body 1. The two sides are slidably positioned, and when the first moving bar 7 and the second moving bar 8 move, they can stably support the sliding. The movement is stable, and when sliding, the convex sliders 78 slide into the convex slide rails 780, making the movement smooth and the support stable. Motor 5 is a forward and reverse motor; motor 5 can be driven in both directions, and can drive the first moving bar 7 and the second moving bar 8 to contract or expand, and can adjust the position of the squeezed leather according to different leather sizes. At the same time, the leather can be moved and its position adjusted by the conveyor belt, with precise and stable positioning. The lower ends of the positioning strip 10 are rounded on both sides, and the overall outer surface of the positioning strip 10 is smoothly polished.
