[0002] Fabric is a commonly used material in decoration, including chemical fiber carpets, non-woven wall cloths, linen, nylon cloth, colored tape, flannel and other fabrics. Fabric plays a considerable role in decorative display and is often the main force that cannot be ignored in the entire sales space. The extensive use of fabric for wall decoration, partitions, and background processing can also form a good commercial space display style. The formation of fabric is naturally inseparable from fabric processing, among which fabric cutting is an important process in production.

[0003] Currently, fabric cutting is mostly done manually by measuring the fabric with a long ruler, cutting it with long scissors, and finally transporting it away. The steps are relatively cumbersome, very time-consuming and labor-intensive, resulting in extremely low work efficiency. Utility Model Content

[0004] The purpose of the utility model is to solve the following shortcomings in the prior art and to propose a fully automatic cloth fixed-length cutting machine.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] The cam is fixedly mounted on the driving roller so as to rotate horizontally on the inner wall of the driving roller, one end of the driving roller passes through the side wall of the driving roller and is connected to a driving component that drives the driving roller to rotate. The driving roller is fixedly sleeved on the first sprocket, and the side wall of the driving roller is provided with a mounting opening. The central rotating shaft is rotatably mounted in the mounting opening, and one end of the central rotating shaft is fixedly sleeved on a disc, and the other end is fixedly sleeved on a second sprocket. A first chain is meshed and wound between the second sprocket and the first sprocket. The surface of the disc is fixedly connected to a boss, and the boss is rotatably sleeved on the cylinder through a connecting rod. Two limiting plates with an L-shaped cross section are fixedly mounted on the inner wall of the driving roller, and the cylinder is fixedly connected to a cutting knife with a surface that slides in contact with the inner walls of the two limiting plates. A unwinding component for controlling the unwinding of the cloth, a guide component for guiding the movement of the cloth, and a transport component for transporting the cut cloth are respectively provided in the machine body.

[0007] In order to better achieve the above-mentioned purpose, the present invention adopts a further technical solution: the unwinding component includes an unwinding roller that rotates horizontally on the inner wall of the machine body, a cloth roll is wrapped around the surface of the unwinding roller, one end of the unwinding roller passes through the side wall of the machine body and is fixedly sleeved with an unwinding gear, a third sprocket is fixedly sleeved on the central rotating shaft, the unwinding gear is meshed with an incomplete gear, the incomplete gear is fixedly sleeved with a fourth sprocket through an auxiliary rotating shaft, and a second chain is meshed and wrapped around the third sprocket and the fourth sprocket.

[0008] In order to better achieve the above purpose, the present invention adopts a further technical solution: the guide component includes a guide plate fixedly installed on the inner wall of the machine body, one end of the guide plate is located directly below the unwinding roller, and the other end is located directly above the transport component, and the guide plate passes through the moving path of the cutter.

[0009] In order to better achieve the above purpose, the present invention adopts a further technical solution: the transport component includes a driven roller that is horizontally rotatably mounted on the inner wall of the machine body, and a transmission belt is wound between the active roller and the driven roller.

[0010] In order to better achieve the above-mentioned purpose, the present invention adopts a further technical solution: the driving component includes a driving motor fixedly sleeved on one end of the active roller, the driving motor is fixedly installed on the side wall of the machine body through two fixing plates, and the output shaft of the driving motor is fixedly connected to one end of the active roller.

When the cloth unrolled by the discharging roller passes through the guide plate, it will be cut by the cutter above it. The cut cloth will fall onto the conveyor crawler and then be transported to the cloth collecting frame, completing the cutting and subsequent transportation of the cloth. The whole process is driven by the motor to achieve fully automatic production, without manual operation, reducing labor costs and increasing cloth cutting efficiency; at the same time, when the central rotating shaft rotates, it will cooperate with the third sprocket, the second chain, the fourth sprocket and the auxiliary rotating shaft to drive the incomplete gear to start rotating, and then the discharging gear meshed with the incomplete gear will drive the discharging roller to rotate periodically, controlling the cloth on the cloth roll to be regularly pulled out onto the guide plate. Compared with the traditional discharging roller for releasing cloth that rotates continuously, this discharging method can reduce the error between the cut cloth lengths and better meet the needs of fixed-length cutting.

A disc 7 is fixedly sleeved on one end of the central rotating shaft 6, and a second sprocket 4 is fixedly sleeved on the other end. A first chain 5 is meshed and wound between the second sprocket 4 and the first sprocket 3. A boss 8 is fixedly connected to the surface of the disc 7, and the boss 8 is rotatably sleeved on the cylinder 10 through the connecting rod 9. Two limiting plates 11 with L-shaped cross-sections are fixedly installed on the inner wall of the body 1. The cylinder 10 is fixedly connected to a cutter 12 whose surface is in sliding contact with the inner walls of the two limiting plates 11. The body 1 is respectively provided with a roll-out component for controlling the unwinding of the cloth, a guide component for guiding the movement of the cloth, and a transport component for transporting the cut cloth.

[0021] Start the drive motor 23, and the drive motor 23 will drive the first sprocket 3 to start rotating through the active roller 2, and then the first sprocket 3 will drive the second sprocket 4 to start rotating through the first chain 5, and the second sprocket 4 will drive the central shaft 6 to rotate, and then drive the disc 7 to start rotating. Because one end of the connecting rod 9 is connected to the boss 8 on the disc 7, it will start circular motion, and because the other end of the connecting rod 9 is connected to the cutter 12 through the cylinder 10, and under the restriction of the limiting plate 11, the disc 7 will eventually carry the cutter 12 to achieve regular reciprocating motion in the vertical direction. The cloth unrolled by the unwinding component will be cut by the cutter 12 when passing through the guide component, and the cut cloth will be transported to the designated position through the transport component.

[0022] The unwinding component includes an unwinding roller 13 that rotates horizontally on the inner wall of the body 1, and a cloth roll 14 is wound around the surface of the unwinding roller 13.
