Double-station automatic line drawing machine for shoe materials

Abstract

The invention discloses a double-station automatic line drawing machine for shoe materials. The double-station automatic line drawing machine includes a machine frame; a workbench is arranged on the machine frame; a line drawing device is arranged above the workbench; the workbench comprises two vacuum adsorption plates which are arranged on the rack up and down and are of a hollow structure; thetwo sides of the upper vacuum adsorption plate extend forwards to form communicated transverse pipes; the transverse pipe is connected with a first draught fan through a first hose; the lower vacuum adsorption plate is provided with two connector pipes, the connector pipes are connected with a second draught fan through second hoses; a plurality of adsorption holes are formed in the upper surfaceof the vacuum adsorption plate; a template is fixed to the vacuum adsorption plate; a plurality of positioning frames used for containing shoe materials are hollowed out in the template; and a double-station switching mechanism is arranged on the rack. Double-station operation is achieved, cut pieces are positioned through the positioning frame, line drawing can be automatically completed, production is convenient and rapid, manpower is saved, the production quality is improved, and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of automatic line drawing machines, in particular to a double-station automatic line drawing machine for shoe materials. Background technique [0002] At present, in the production process of shoes, balls, toys and leather goods in the prior art, it is necessary to draw lines on the raw materials, and then process or position according to the outline drawn by the lines. Now take shoemaking as an example. When making shoes, Generally, a single piece of shoe upper is punched out on the whole roll of leather through a punching machine. In order to make the hemming even and the shoe shape accurate, it is necessary to draw a line at the connecting edge of the shoe upper, and fold the edge according to the area within the drawn line. , so that it is well-proportioned; generally, a template with the same shape and size as the upper is placed on the upper of the shoe, and a wire groove is engraved in the template, a...

Ink, frame and screen waste, not conducive to environmental protection

[0003] In the patent No. CN201821088908.2, a double-station visual line drawing machine is disclosed, including a frame, which is equipped with a double-station conveyor belt, and the shoe materials that need to be drawn are released into the double-station conveyor belt, located on the frame The visual positioning device above takes real-time photos of shoe materials, and the computer control device drives the X-Y transmission mechanism, up-and-down lifting mechanism and line-drawing mechanism to move according to the real-time photos, draws lines according to the set trajectory, and automatically completes the line-drawing through visual positioning. The production is convenient and quick, but this kind of line drawing machine equipment is complicated, the cost is high, and the machine vision has certain limitations. At present, the graphics recognition processing technology for the outline of irregular shoe upper pieces is not yet mature, resulting in low precision of line drawing. Under the influence of different factors such as curved surface, depth and direction of scratches, reflection of materials, different material surfaces reflect different light, etc., the market utilization rate of visual line drawing machines is still relatively low.

[0004] The patent No. CN201711228315.1 discloses a fully automatic intelligent line drawing machine and its line drawing method, including a workbench, a feeding device, a camera positioning device and a line drawing device. The invention has high line drawing efficiency and can reduce worker labor. The advantages of strength and low production cost, but the internal cavity of the workbench is large, the vacuum adsorption effect on the pieces is not good, and a high-power fan is required, which increases labor costs
