Description

Technical Field

[0001] The present invention relates to the field of processing equipment for umbrella accessories, and particularly to a hemming device for umbrella cloth based on image reading. Background Art

[0002] At present, in order to improve the aesthetic degree of umbrellas, lace strips are usually arranged on the umbrella surfaces of many umbrellas. The lace strips are generally realized by sewing. In order to sew both sides simultaneously, basically two sewing machines need to be configured at present, and each sewing machine requires a staff member. In this way, a great deal of manpower, material resources and time are consumed. In the current increasingly competitive environment, it is simply impossible to control costs and there is an urgent need for innovation.

[0003] The Chinese invention patent with the patent application number 201711488440.6 and the patent name of "A Double-Head Ultrasonic Hemming Machine for Umbrella Cloth" discloses a double-head ultrasonic hemming machine for umbrella cloth. Through the arrangement relationship among the edge cloth winding mechanism, the hemming mechanism and the conveying mechanism, the conveying mechanism keeps the umbrella cloth in a tensioned state all the time, so that there can be a certain distance between the edge cloth winding mechanism and the hemming mechanism, but still ensure high-quality hemming. Since the traditional sewing method is changed, the cost is greatly reduced and the production efficiency is improved.

[0004] Although the above patent realizes automatic hemming of umbrella cloth, the following problems still exist: Before the umbrella cloth starts to be processed, the end of the umbrella cloth needs to be drawn out and passed through the edge cloth winding mechanism, the hemming mechanism and the conveying mechanism in sequence. Only at this time can the conveying mechanism drive to realize automatic hemming of the umbrella cloth. It is time-consuming and laborious for workers to draw out the end of the umbrella cloth and pass it through the edge cloth winding mechanism, the hemming mechanism and the conveying mechanism in sequence. And in order to ensure the safety of workers, the hemming mechanism cannot be started. Therefore, the end section of the umbrella cloth cannot be hemmed, resulting in waste of materials.

It further includes a tension output device arranged on the frame between the cloth winding wheel and the edge winding device for adjusting the tension of the umbrella cloth during the output of the umbrella cloth and turning the umbrella cloth to output it to the edge winding device, and a flattening device arranged on the frame at a position corresponding to the pressing device for flattening the fixed area after the pressing device presses and fixes the edges of both sides of the umbrella cloth to the umbrella cloth. A traction device is arranged on the frame at a position corresponding to the flattening device for clamping the end of the umbrella cloth before the cloth winding wheel outputs and pulling the end of the umbrella cloth to sequentially pass through the tension output device, the edge winding device, the pressing device, and the flattening device so that the umbrella cloth can complete the edge pressing and fixing when passing through the pressing device from the end, and the traction device is also used for winding the umbrella cloth flattened by the flattening device.
