Description

Technical Field

[0001] The invention relates to the technical field of line drawing machines, and in particular to a multi-ink cartridge calibration and positioning method for an automatic line drawing machine. Background Art

[0002] At present, in the prior art, during the production process of shoes, balls, toys and leather goods, it is necessary to draw lines on the raw materials, and then process or position them according to the outline drawn by the lines. Taking shoemaking as an example, when making shoes, a single-piece upper is generally punched out on a whole roll of leather by a punch press. In order to make the folding edge uniform and the shoe pattern accurately shaped, it is necessary to draw lines at the connecting edge of the upper, and fold the edges according to the area within the lines, so that it is symmetrical; generally, the lines are drawn by placing a template with the same shape and size as the upper on the upper, and a wire groove is engraved in the template, and then drawing lines along the wire groove edge of the template. These line marks are often used to guide the tailor to sew and bond the shoe materials, and these line marks can further guide the tailor to make decorative pattern marks at the required position of each shoe material component. The traditional working method is to print lines by a silk screen screen to realize the splicing and positioning method of the cut pieces. There are some disadvantages of manual silk screen printing. For example, it is difficult to operate, labor-intensive, and inefficient. Ink, plate frame and silk screen are wasted, which is not conducive to environmental protection.

[0003] Patent No. CN201821088908.2 discloses a double-station visual line marking machine, including a frame, the frame is provided with a double-station conveyor belt, the shoe materials that need to be marked are released into the double-station conveyor belt, the visual positioning device located above the frame takes real-time photos of the shoe materials, and the computer control device drives the XY transmission mechanism, the up and down lifting mechanism and the line marking mechanism to move according to the real-time photos, and the line is drawn according to the set trajectory. Through visual positioning, the line drawing is automatically completed, and the production is convenient and fast. However, this type of line marking machine is complex and costly, and the machine vision has certain limitations. At present, the graphic recognition and processing technology for the contour of irregular shoe upper pieces is not yet mature, resulting in low line drawing accuracy. Under the influence of different factors such as the arc surface, the depth and direction of scratches, the reflection of the material, and the different reflection of different light on the surface of different materials, the market utilization rate of the visual line marking machine is still relatively low.

After the inkjet cartridges 2 are installed, the inkjet cartridge 2 most protruding from the sliding frame 1 is set to be fixed, and the remaining inkjet cartridges 2 are adjusted in turn along the sliding frame 1 toward the inside of the line drawing machine. After the inkjet cartridges 2 are adjusted, the overall mounting plate 3 is driven to move up, the screen pressing is placed, and then the mounting plate 3 is reset, and the positioning ink cartridge assembly is at the vertex of the lower right corner of the screen pressing as the printing starting point to start printing.

[0025] The top of the mounting plate 3 is telescopically connected to the sliding frame 1 , and a plurality of slide grooves 4 are provided on the side of the mounting plate 3 away from the sliding frame 1 . The number of the slide grooves 4 is consistent with the number of the inkjet cartridges 2 , and the bottoms of the slide grooves 4 are all conductive.

[0026] Meanwhile, a sliding plate 5 is clamped at the bottom of the inkjet cartridge 2 , and a through groove 6 corresponding to the inkjet port of the inkjet cartridge 2 is provided on the sliding plate 5 .

[0027] The sliding plate 5 is in an L-shaped structure. A piston rod 7 is fixed to the end of the sliding plate 5 close to the sliding frame 1. The end of the piston rod 7 away from the sliding plate 5 is connected to a first cylinder 8. A plurality of first cylinders 8 are independently controlled.

[0028] The first cylinder 8 is electrically connected to a control valve, and the control valve is connected in series with a timing switch. The control valve is used to control the first cylinder 8 to open, and the timing switch is set to control the interval time to be 1-3s.

[0029] The sliding plate 5 slides along the slide groove 4 inside the mounting plate 3, wherein the sliding plate 5 is driven to move by the first cylinder 8, and when the first cylinder 8 is driven, each sliding plate 5 can move independently, and when the sliding plate 5 moves, the ink cartridge clamped therewith is driven to move, and the sliding plates 5 move independently, and thus the protruding spacing between two adjacent ink cartridges can be adjusted.

When the inkjet cartridge 2 is positioned and adjusted, the first cylinder 8 is turned on to drive the sliding plate 5 to move, and the first cylinder 8 is automatically closed after 2s, so that the stroke distance of the inkjet cartridge 2 is adjusted each time and is related to the power of the first cylinder 8, and the single movement of the inkjet cartridge 2 can be achieved by installing first cylinders 8 with different powers. Dynamic distance control can automatically locate the position of the inkjet cartridge 2 according to the real-time settings of the printer; during printing operation, the second cylinder 10 can be used to drive the mounting plate 3 to move up and down to control the placement of the screen press. When the mounting plate 3 rises, the screen press is placed. At the same time, the height of the inkjet cartridge 2 from the screen press can be adjusted according to the thickness of the leather cutting piece.
