Description

Technical Field

[0001] The utility model relates to the technical field of tape cutting machines, in particular to a double-head edge-folding tape cutting machine. Background Art

[0002] Garments and luggage usually have straps. Some strap materials are made of high-molecular materials such as nylon and polyester fiber. Such woven tapes are relatively smooth. During the processing of garments and luggage, the woven tapes will be cut according to the design requirements. Such cut edges are prone to thread shedding, affecting the sewing effect, causing material waste, and greatly increasing the production cost.

[0003] Most of the existing technologies are manual operations. Workers heat the cut position of the woven tape with an electric iron (usually need to be heated to about 250 °C, and most high-molecular materials will melt at this temperature), then fold it up, and then sew it. During the heating and folding process, it is easy to scald the operators. Both ends of a woven tape need to be melted and folded, and the quality of the folded woven tape cannot be guaranteed, wasting a lot of manpower and time, with extremely low work efficiency. The operators will also inhale harmful fumes. Moreover, completing this process occupies a large area, is not easy to manage, and is prone to safety hazards.

[0004] There are also various hot-melt tape cutting machines on the market, but their structures are relatively complex, with high requirements for workers, complex operation processes, low work efficiency, and inconvenient maintenance. The products cut can only be cut into strips and cannot be folded and fused at both ends, unable to meet the market demand.

[0005] Therefore, engineers and technicians in this field are required to develop a double-head edge-folding tape cutting machine with a simple structure, convenient use, high production efficiency, and safety and reliability. Content of the Utility Model

[0050] The working principle of the present utility model:

[0051] The present utility model is controlled by a computer to achieve full-automatic operation. The computer controls the cutting knife to first cut the webbing, and then the corresponding double-sided heating knife 14 descends to the working position. At this time, the rotary folding device starts to work and rotates a certain angle to press the webbing on the heating knife. After the surface of the webbing is melted, the heating knife withdraws from the working position. At this time, the rotary folding device continues to rotate until the two sides of the webbing come into contact, and after pressing for a certain time, the rotary folding device returns to its original position. The feeding mechanism conveys the webbing forward. At this time, the clamping mechanism 5 enters the working position and clamps the port of the webbing that has completed the hemming. After the feeding mechanism 2 and the clamping mechanism 5 run with the webbing to the preset webbing length, the feeding mechanism stops feeding. At this time, the cutting knife cuts the webbing, and the double-sided heating knife 14 runs to the working position, and the rotary folding device starts to work to complete the hemming of the other port of the webbing. After the hemming is completed, the clamping mechanism runs with the webbing to the finished product placement area, and the clamping mechanism releases, and the webbing drops.
