For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. The following is a description of the embodiments of the present invention based on its overall structure.

[0027] The utility model provides an automatic strapping device, comprising a cloth 1, and also comprising: a rotating shaft 2, a tensioning roller 3, a fixing device 4, a driving unit 5 and a resetting unit 6, wherein the rotating shaft 2 and the tensioning roller 3 are placed side by side, the resetting unit 6 is arranged on the roller of the tensioning roller 3, and is used for resetting the tensioning roller 3, the driving unit 5 is arranged at the rotating shaft 2, and is used for rotating the rotating shaft 2, the tensioning roller 3 is wrapped with the cloth 1, and the fixing device 4 is arranged at the rotating shaft 2, and is used for fixing and disassembling the rotating shaft 2.

[0028] Before work, place the tensioning roller 3 and the rotating shaft 2 side by side, and then rotate the tensioning roller 3 in the opposite direction of the rotating shaft 2. For example, if the rotating shaft 2 is on the left, rotate the tensioning roller 3 clockwise, and vice versa. After the tensioning roller 3 rotates to the limit, place the cloth 1 on the fixing unit, which is fixedly connected to the tensioning roller 3. Then, withdraw the force applied to the tensioning roller 3, and the tensioning roller 3 recovers under the action of the reset unit 6. The reset unit 6 includes a coil spring 601. The middle part of the rotating shaft of the tensioning roller 3 is hollow. The coil spring 601 is arranged in the middle part of the tensioning roller 3. The output end of the coil spring 601 is fixedly connected to the rotating shaft of the tensioning roller 3. Support rods 7 are arranged at both ends of the tensioning roller 3. The rotating shaft of the tensioning roller 3 is rotatably connected to the support rod 7, and the end of the coil spring 601 away from the tensioning roller 3 is fixedly connected to the support rod 7. The coil spring 601 drives the cloth 1 to be wound around the tension roller 3, and then one end of the cloth 1 is connected to the rotating shaft 2. The driving unit 5 drives the rotating shaft 2 to rotate. The driving unit 5 includes a rotating motor 501 and a control panel 502. The control panel 502 can control the rotation speed and torque of the rotating motor 501. The output end of the rotating motor 501 is fixedly connected to the rotating shaft of the rotating shaft 2. The rotation direction of the rotating shaft 2 is opposite to the reset direction of the tension roller 3. Figure 1 The arrow direction indicates the force direction of the rotating shaft 2 and the tensioning roller 3. The torque of the driving unit 5 is slightly higher than the torque of the resetting unit 6 when it is reset. The rotating shaft 2 rotates to drive the cloth 1 to wrap around the rotating shaft 2. The resetting unit 6 continuously applies a force to the cloth 1 in the direction of the tensioning roller 3, so that the cloth 1 is kept in a taut state. This process can be completed by one person, thereby improving the efficiency of tie-dyeing.

[0029] End plates 401 are provided at both ends of the rotating shaft 2. The size of the end plates 401 is larger than that of the rotating shaft 2. The end plates 401 and the rotating shaft 2 are detachable. The fixing device 4 includes fixing holes provided on the end plates 401. The fixing holes are provided on the inner sides of the two end plates 401. Threads are provided in the fixing holes. External threads 402 matching the fixing holes are provided on both sides of the rotating shaft 2.

[0030] A rotating connection part 404 connected to the output shaft of the motor is provided on the outer side of an end plate 401. The tightening direction of the inner thread of the fixing hole is opposite to the rotation direction of the motor. When installing the rotating shaft 2, the rotating shaft 2 is first connected to the two end plates 401 through threads, and then the rotating connection part 404 is connected to the output shaft of the rotating motor 501. The connection method is preferably a detachable coupling. The rotating motor 501 drives the end plate 401 to rotate. Since the tightening direction of the inner thread of the fixing hole is opposite to the rotation direction of the motor, when the rotating motor 501 rotates, the rotating shaft 2 is simultaneously subjected to the tension of the tensioning roller 3. The connection between the fixing hole and the rotating shaft 2 will tend to be subjected to force in the tightening direction, thereby obtaining a good anti-loosening and anti-slip effect.

[0031] Two moving rods 403 are provided, and the two end plates 401 are rotatably connected to one moving rod 403 respectively, and the rotating motor 501 is fixedly connected to one moving rod 403. Because the cloth 1 has different widths, the width of the cloth 1 is not necessarily the same during each operation. Therefore, the rotating shaft 2 is provided with a variety of length specifications. The moving rod 403 moves relative to the ground to cope with the rotating shaft 2 of different lengths. The moving rod 403 adopts a lockable universal wheel to move relative to the ground. After the installation is completed, the moving rod 403 is locked to prevent the moving rod 403 from sliding during the operation.

[0032] In order to ensure that the end of the cloth 1 can continue to maintain the tension state when it is separated from the tension roller 3, the two ends of the tension roller 3 are larger than the middle size, and the cloth 1 is wrapped around the middle of the tension roller 3. One end of the two ends of the tension roller 3 is provided with a groove concave toward the axis, and a counterweight rod 8 is slidably connected in the groove. One end of the cloth 1 is fixedly connected to the configuration rod. When the end of the cloth 1 is separated from the tension roller 3, the counterweight rod 8 on the tension roller 3 is brought down along the groove. The counterweight rod 8 will continue to pull the cloth 1 until the cloth 1 is completely wrapped around the rotating shaft 2, and then the counterweight rod 8 is removed to complete the strapping.

[0033] The rotating shaft 2 is made of a bendable material, such as a spring or a bamboo tube. A layer of cloth or paper is wrapped on the rotating shaft 2 to maintain the smoothness of the rotating shaft 2. By setting the bendable rotating shaft 2, it can be bent when the cloth 1 is wrapped, so that the tie-dyeing effect is improved. When the rotating shaft 2 is put into the steamer at a later time, in order to avoid the length of the rotating shaft 2 being longer than the length of the steamer and unable to be put in, the rotating shaft 2 is bent to reduce the distance between the two ends so that the rotating shaft 2 can be put into the steamer as a whole. The moving rod 403 uses a lockable universal wheel to move relative to the ground, and the moving rod 403 can be locked. During the working process, by locking the moving rod 403, the rotating shaft 2 cannot be bent, so it will not affect the wrapping tightness of the cloth 1. When the cloth 1 is pulled out from the tensioning roller 3 to the rotating roller, the two ends of the end of the cloth 1 can be connected to the rotating roller by detachable fixing measures such as tape or thumbtacks. After the rotating shaft 2 rotates one circle, the force on the end of the cloth 1 will be reduced, so the end of the cloth 1 will not be stressed for a long time.
