[0067] Generating first control information based on the first request information, the first control information is used to control the limiting cutting mechanism to start;

[0068] The first control information is sent to the limiting cutting mechanism to control the limiting cutting mechanism to start limiting;

[0069] The second request information is obtained, which is generated by the limiting cutting mechanism after starting;

[0070] The second control information and the third control information are generated based on the second request information, the second control information being used to control the lead screw driving mechanism to start, and the third control information being used to control the wrapping smoothing mechanism to start;

[0071] The second control information is sent to the lead screw driving mechanism to control the lead screw driving mechanism to start;

[0072] The third control information is sent to the wrapping smoothing mechanism to control the wrapping smoothing mechanism to start;

[0073] The controller 3 generates the first control information after receiving the first request information, and sends the first control information to the limiting cutting mechanism to control the limiting cutting mechanism to start limiting. Then, the controller obtains the second request information. The controller generates the second control information and the third control information after receiving the second request information. The controller controls the lead screw driving mechanism to start through the second control information, and controls the wrapping smoothing mechanism to start through the third control information.

[0074] As shown in Figure 12 , as an embodiment of the present application, the specific triggering method of the limiting cutting mechanism includes the following steps:

[0075] The first trigger information is obtained, which is generated after the cloth laying machine 2 moves to a predetermined position;

[0076] The first request information is generated based on the first trigger information;

[0077] The first request information is sent to the controller 3 to make the controller 3 generate the first control information;

[0078] The limiting cutting mechanism obtains the first trigger information after being moved to the predetermined position by the cloth laying machine 2. Then, the limiting cutting mechanism generates the first request information and sends it to the controller 3.

[0079] As shown in Figure 13 , as an embodiment of the present application, the specific starting method of the lead screw driving mechanism includes the following steps:

[0080] The second control information is obtained;

[0081] The second control information is sent to the lead screw driving mechanism to control the lead screw driving mechanism to start;

[0082] Wherein, the second control information is generated after the controller 3 acquires the second request information, and then the controller 3 controls the screw driving mechanism to start through the second control information.

[0083] The working principle of the embodiment is as follows: the fixed mechanism first fixes the unwinding end of the cloth, then the cloth unwinds and lays flat on the plane of the base 1 under the driving of the cloth laying machine 2, after the cloth moves to the predetermined position under the driving of the cloth laying machine 2, the controller 3 first controls the limiting cutting mechanism to start, the limiting cutting mechanism first moves downward, so that the limiting cutting mechanism first fixes the cloth, and then the cloth is cut, which is beneficial to cutting the predetermined position of the cloth by the limiting cutting mechanism, on the one hand, it is beneficial to avoid the situation that the end of the cloth is not neat when the limiting cutting mechanism cuts the cloth, on the other hand, the end of the cloth is limited to prevent the situation that the cloth shrinks after being cut, the sliding block 8 is slidingly connected with the U-shaped sliding seat 9, and the U-shaped sliding seat 9 and the sliding block 8 are connected through the screw driving mechanism, so that after the cloth is fixed, the screw driving mechanism drives the U-shaped sliding seat 9 to slide along the sliding block 8, the screw driving mechanism is composed of a motor, a threaded rod and the like, the screw driving mechanism is a mature technology, which will not be described one by one here, the U-shaped sliding seat 9 drives the limiting cutting mechanism to cut the cloth along the predetermined track, and the U-shaped sliding seat 9 also synchronously drives the wrapping smoothing mechanism to move, when the wrapping smoothing mechanism passes through the end of the cloth after cutting, the wrapping smoothing mechanism clamps the end of the cloth after cutting, then the wrapping smoothing mechanism reciprocally irones the end of the cloth after cutting through heating of the wrapping smoothing mechanism, so as to reduce the situation that the end of the cloth shrinks and wraps after the cloth is cut by the limiting cutting mechanism.

[0084] The basic principle, main features and advantages of the present application are shown and described above. It should be understood by those skilled in the art that the present application is not limited by the above embodiments, the above embodiments and descriptions in the specification are only the principles of the present application, various changes and improvements can be made without departing from the spirit and scope of the present application, and these changes and improvements all fall within the scope of the claimed present application.
