Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of line drawing equipment, and particularly relates to a visual inkjet line drawing machine. BACKGROUND

[0002] At present, the processing of shoes, balls, toys and leather goods on the market needs to draw lines on raw materials during the production process, and then the lines drawn are used for processing or positioning. Taking shoemaking as an example, when shoes are made, a single shoe surface is generally punched out on a whole roll of leather by a punch. In order to make the folded edge uniform and the shoe pattern accurately shaped, lines need to be drawn at the connecting edge of the shoe surface, and the folded edge is folded according to the area inside the lines. Only in this way can the shoe surface be uniform. Generally, a template with the same shape and size as the shoe surface is placed on the shoe surface, the template has a line groove, and then lines are drawn along the edge of the line groove of the template. These line marks are often used as guides for seamsters to sew and bond shoe materials, and the line marks can further guide seamsters to make decorative pattern marks on the required positions of the shoe material components.

[0003] The existing Chinese patent with the authorization announcement number CN222661732U and the announcement date of 2025-03-25 discloses an automatic visual inkjet line drawing machine. The machine comprises a rack, a conveying device for conveying materials, a visual positioning device for shooting and uploading the position of the materials on the conveying device, a pressing device for fixing and flattening the materials on the conveying device, and an inkjet line drawing device for drawing lines on the materials on the conveying device are installed on the rack. The inkjet line drawing device is located above the conveying device and is electrically connected with the visual positioning device. The pressing device comprises a driving source installed on the rack, a driving roller group connected with the output end of the driving source, and a pressing net wound on the driving roller group. The driving roller group drives the pressing net to rotate and synchronously moves with the conveying surface of the conveying device in the same direction. The pressing net is arranged above the conveying device and forms a conveying channel for conveying materials with the conveying device.

[0004] In the above-mentioned process, the material to be drawn is placed on a conveyor. As the conveyor moves, the material is positioned within the conveying channel formed between the pressing mesh in the pressing device and the conveyor. The pressing mesh then fixes and flattens the material. With the conveyor belt and the pressing mesh moving synchronously in the same direction, a vision positioning device on the frame takes a picture of the material's position. The device then calculates the drawing trajectory based on the material's shape and placement. Finally, the information processing module sends an electrical signal for the drawing trajectory to the inkjet drawing device, enabling the inkjet drawing device to complete the drawing within the corresponding zone. Regarding the aforementioned technology, the inventors believe that the pressing mesh, wound around the drive roller assembly, is prone to deformation or elongation during long-term operation and high-speed rotation. This can cause relative slippage or idling between the pressing mesh and the drive roller assembly, affecting the stability of the material's transmission between the conveyor and the pressing device, and consequently, the quality of the drawn lines.
