[0045] In the strap buffer mechanism 4, the strip-shaped strap is wound between the smooth roller 48 and the patterned roller 47 in sequence.

The lifting belt is attached to the product by the support arm 62 as the support arm 62 rotates, and the lifting belt is cut by two cutter mechanisms. The cutting process of the cutter mechanism is that the guide wheel 645 contacts the slope 631 on the abutment block 63, so that the guide wheel 645 is pushed during the rotation process, so that the fixed block 644, the connecting rod 642 and the cutter 646 are all moved relative to the limit block 641, so that the cutter 646 extends out of the support arm 62, thereby cutting the lifting belt. After the guide wheel 645 is separated from the abutment block 63, the connecting rod 642 is reset under the pulling force of the reset spring 643, and the cutter 646 retreats into the support arm 62, wherein the abutment block 63 is installed on the frame of the lifting belt sticking machine.

[0052] The function of the pressing assembly 65 is that during the bonding process, the pressing wheel 653 can press the strip-shaped handle onto the polyurethane bonding part 621 as the support arm 62 rotates, thereby ensuring the bonding effect. The roller 654 cooperates with the cam 655 to make the two pressing wheels 653 abut against or away from the polyurethane bonding part 621. The connecting rod 651 is driven by the roller 654 to rotate relative to the rotating shaft, thereby realizing the movement of the pressing wheel 653.

The previous support sheet 3210 used a single point contact with the material roll barrel core, but now it is changed to a toothed multi-point contact, which improves the friction with the inner wall of the material roll barrel core and eliminates the slipping phenomenon. In addition, the transmission component and the support component of the material tray 32 are made and assembled separately, which can improve the concentricity of the entire material tray 32 and reduce the assembly precision requirements, thereby improving the efficient production efficiency of the material tray 32, and making the later installation and maintenance more convenient.

[0055] Preferably, a side photoelectric sensor 410 capable of detecting the counterweight 45 is provided on the buffer fixed bottom plate 41 at one side of the lifting plate 44 . The side photoelectric sensor 410 is used to detect the position of the lifting plate 44 .

[0056] Preferably, a lower photoelectric sensor 411 capable of detecting the belt-shaped handle is provided between the feeding patterned roller and the feeding smooth roller on the buffer fixed bottom plate 41. The lower photoelectric sensor 411 is used to detect whether the belt-shaped handle is disconnected.

[0057] Preferably, protective covers 647 are provided at both ends of the support arm 62 for the cutter 646 to extend in and out. The protective covers 647 are in contact with the belt-shaped handle, and when the cutter 13 is not extended, the belt-shaped handle is prevented from contacting the cutter 13, thereby reducing the harm to the operator.

[0058] Preferably, the support arm 62 is provided with a limiting groove 623 capable of abutting against two sides of the fixing block 644. The provision of the limiting groove 623 can make the process of the cutting knife 646 extending in and out more stable and accurate.

[0059] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
