Among them, the old cloth 200 refers to the cloth roll that is about to be used up, and the new cloth 100 refers to the cloth roll that is being replenished.

[0032] The automatic cloth joining device of the shaping machine transfers the new cloth to the old cloth through the cloth moving robot, and sews the new cloth and the old cloth end to end through the cloth sewing mechanism, thereby realizing automatic cloth joining, saving time and labor, and the new cloth head is clamped from bottom to top by the clamping claw, and the naturally hanging flat cloth head cooperates with the clamping claw, which can effectively avoid the situation that the clamping claw cannot effectively grasp the cloth due to the uneven cloth head.

[0033] Correspondingly, the interior of the cloth storage bucket 2 is a cavity with an upper opening, and the exterior of the cloth storage bucket 2 is larger at the top and smaller at the bottom, or a flange extends outward from the opening of the cloth storage bucket 2, so that the cloth head of the new cloth 100 naturally hangs down when it extends from the opening. The external shape of the cloth storage bucket 2 provides space for the cloth head of the new cloth to naturally hang down, and at the same time makes way for the clamping action of the clamping claw.

[0034] Furthermore, the cloth moving robot 3 includes a transverse movement mechanism 31 and a vertical movement mechanism 32, the clamping jaw 30 is arranged on the vertical movement mechanism 32, the clamping jaw 30 includes a clamping jaw body 311 and a plurality of clamping plate groups 312 arranged on the clamping jaw body 311, the clamping plate group 312 includes two cloth clamping plates 3121 that can be relatively clamped, a pneumatic clamping jaw 3122 that drives the two cloth clamping plates 3121 to clamp relatively, and a first detection switch 3123 for detecting whether the cloth head is clamped in place. Among them, the transverse movement mechanism 31 and the vertical movement mechanism 32 can adopt conventional linear modules, and the first detection switch 3123 can adopt detection switches such as photoelectric switches, which will not be described in detail here. The clamp utilizes multiple groups of clamping plates to clamp cloth ends simultaneously, which can not only meet the effective gripping requirements of cloth ends of different widths, but also facilitate modular manufacturing. The clamping state is detected by the first detection switch of each group of clamping plates. When it is detected that each group of clamping plates is clamped in place, the cloth roll is transferred, so that the clamped cloth ends are smoother.

[0035] Furthermore, the cloth sewing mechanism 1 includes a cloth guide groove 11 and a first traction roller 12. The lower end of the cloth guide groove 11 is provided with a cloth guide outlet 111 for merging the cloth ends of the new cloth 100 with the cloth ends of the old cloth 200.
