Description

Technical Field

[0001] The utility model relates to the technical field of automatic welding and cutting equipment, in particular to an automatic welding and cutting equipment for webbing. Background Art

[0002] In the garment manufacturing industry, overlapping multiple layers of fabric to create webbing is a widely used process. Traditional processes involve sewing on a sewing machine, with manual trimming of threads and edges, or using ultrasonic lace machines for rolling welding followed by trimming of the edges. Sewing on a sewing machine creates seams, and ultrasonic rolling welding requires manual cutting and removal of the edges. Therefore, both processes are extremely inefficient for automation.

However, ultrasonic continuous welding and cutting can achieve rapid, one-step production. This significantly improves production efficiency and saves labor and process costs. The drawback of the first existing solution is that the use of a continuous tape-line process ensures product consistency, but the only drawback is that for strip-shaped products, there is waste material at the end or beginning, which requires manual or automated removal.

If the webbing 90 on the lower cutting die is not severed after the ultrasonic welding device 4 welds and cuts, it indicates that the lower cutting die has broken or the ultrasonic welding device is not working properly. The second detection sensor 21 then sends a signal to the control device. If the webbing 90 on the lower cutting die is severed after the ultrasonic welding device 4 welds and cuts, it indicates that the ultrasonic welding device 4 and the lower cutting die are properly cutting and welding the webbing 90.

[0043] The working principle of this utility model is:

[0044] The worker passes the front end of the webbing 90 through multiple tensioning rollers 18, and then through the webbing support plate 13. The feeding clamp cylinder 7 clamps the webbing 90. Then the worker starts the utility model through the start-stop switch 22. The first detection sensor 20 detects in real time whether there is webbing 90 in the webbing tensioning device 12. The servo motor 61 drives the transmission screw 63 to rotate forward. The transmission screw 63 drives the horizontal slider 62 to slide forward horizontally. The horizontal slider 62 drives the feeding clamp cylinder 7 to slide forward horizontally. The feeding clamp cylinder 7 drives the webbing 90 horizontally forward. Move, the jig translation cylinder drives the lower cutting die 14 to slide horizontally to the bottom of the webbing 90. At this time, a part of the webbing 90 has crossed the lower cutting die 14. The second detection sensor 21 detects whether there is webbing 90 on the lower cutting die 14. Then the welding lifting cylinder 5 drives the ultrasonic welding device 4 to descend, and the ultrasonic welding device 4 starts to weld the webbing 90 and cut the webbing 90. When the webbing 90 of the utility model is cut and welded by the ultrasonic welding device, the webbing is cut into two sections, including the rear section webbing 91 and the front section webbing 93.

[0045] The servo motor 61 continues to drive the transmission screw 63 to rotate forward, and the feeding clamp cylinder 7 continues to drive the front section of the webbing 93 to move horizontally forward to just above the waste discharge port. Then the shearing translation cylinder 11 drives the pneumatic scissors 9 to slide horizontally, and then the pneumatic scissors 9 start and cut off the front end of the front section of the webbing 93. The generated waste 92 falls to the waste discharge port, and then the blanking translation cylinder 81 drives the blanking clamp cylinder 82 to slide backward, and the blanking clamp clamps the front section of the webbing 93, and the clamp cylinder 7 releases the front section of the webbing. At the same time, the welding lifting cylinder 5 drives the ultrasonic welding device 4 to rise, the jig translation cylinder drives the lower cutting die 14 to slide horizontally back to the initial position, and the blanking clamp cylinder 82 drives the front section of the cut ribbon to move forward. The blanking clamp cylinder 82 releases the front section of the ribbon, and the front section of the ribbon falls onto the blanking inclined plate 15.
