Description

Technical Field

[0001] This application relates to the field of line drawing equipment technology, and in particular to a visual inkjet line drawing machine. Background Technology

[0002] Currently, the processing of shoes, balls, toys, and leather goods involves marking lines on the raw materials during the manufacturing process. The materials are then processed or positioned according to the outlines drawn on these lines. Taking shoemaking as an example, shoe uppers are typically punched from a roll of leather using a punch press. To ensure even folding and accurate shaping of the shoe pattern, lines are drawn at the connecting edges of the upper, and the folding is done along the areas within these lines to achieve a symmetrical appearance. Generally, the markings are done by placing a template with the same shape and size as the upper on the shoe surface. The template has grooves engraved inside, and lines are drawn along the edges of these grooves. These markings are often used to guide the tailor in sewing and gluing shoe materials, and they can further guide the tailor in placing decorative patterns on the required locations for each shoe component.

[0003] Existing automatic line marking equipment typically uses a single line marking head. However, since the edges and corners of the insole are prone to curling up when it is first formed, it affects the accuracy of the line marking. The current solution is to add a high-power exhaust fan below the feeding component. The exhaust fan uses suction to flatten the curled insole and also to fix the insole in place, making it easier for the line marking component to work. However, this structure requires the high-power exhaust fan to work for a long time, resulting in high power consumption and high cost. Utility Model Content

[0004] This application provides a vision inkjet line drawing machine, which features automatic line drawing, convenient and fast production, high line drawing efficiency, and low production cost.

[0005] The visual inkjet line drawing machine provided in this application adopts the following technical solution:

[0006] A visual inkjet line marking machine includes a frame and a conveying device for conveying materials, a visual positioning device for capturing 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 marking device for marking lines on the materials on the conveying device. The inkjet line marking device is located above the conveying device and is electrically connected to the visual positioning device. The pressing device includes a drive source mounted on the frame, a frame mounted on the frame, a drive roller assembly rotatably mounted on the frame and connected to the output end of the drive source, multiple line marking meshes arranged parallel to each other and sequentially wound around the drive roller assembly, and a positioning guide component mounted on the frame. The multiple line marking meshes are respectively limited and passed through the positioning guide component. The drive roller assembly drives the line marking meshes to rotate and moves synchronously in the same direction as the conveying surface of the conveying device. The line marking meshes are arranged above the conveying device and form a conveying channel for conveying materials.

[0007] Preferably, the positioning guide component includes a positioning plate installed on the frame, and multiple positioning slots are sequentially opened on the positioning plate along its length direction, with multiple pressure wire meshes arranged sequentially in the multiple positioning slots.

[0008] Preferably, multiple positioning and guiding components are provided.

[0009] Preferably, the positioning guide further includes a cover plate, which is installed on the positioning plate to cover the multiple positioning slots.

[0010] Preferably, the positioning plate is L-shaped, and the positioning slots are provided on both sides of the positioning plate.

[0011] Preferably, the drive roller group consists of multiple drive rollers arranged in a rectangular shape, and the multiple pressure wire meshes are wound in a ring around the outer surface of the multiple drive rollers. A drive belt is also provided on the multiple drive rollers, and the drive belt is wound in a rectangular shape around the outer surface of the multiple drive rollers.

[0012] In summary, this application includes at least one of the following beneficial technical effects:

[0013] By placing the material to be drawn on the conveying device in sequence, the material is positioned within the conveying channel formed by the pressure mesh in the pressing device and the conveying device. The pressure mesh fixes and flattens the material. The drive source in the pressing device acts on the drive roller group, causing multiple pressure meshes to operate parallel and synchronously under the limiting action of the positioning and guiding components. This achieves synchronous movement of the conveying device and the pressure mesh along the same plane. At this time, the vision positioning device on the frame takes a picture of the material to be drawn in the conveying channel, and then the inkjet drawing device completes the drawing work in the corresponding zone. This method has the advantages of automatic drawing, convenient and fast production, high drawing efficiency, and low production cost.

[0014] By setting positioning guides at multiple drive rollers, multiple pressure wire meshes are arranged sequentially in the positioning slots on multiple positioning guides. This causes the multiple pressure wire meshes to run parallel and synchronously under the limiting action of the positioning guides, improving the stability of the pressure wire meshes in fixing, flattening and synchronously conveying the material to be drawn, thereby improving the drawing quality of the inkjet drawing device in the corresponding zone.

[0015] By setting a cover plate on the positioning plate to cover and seal multiple positioning slots, multiple pressure wire meshes are sequentially inserted into multiple positioning slots, thereby achieving the purpose of circumferential line limiting when the pressure wire meshes move, and thus improving the stability of the pressure wire meshes in the pressing device and the conveying device in conveying the material to be marked.

The inkjet line drawing device 5 is located above the conveying device 2 and is electrically connected to the visual positioning device 4.

[0025] Among them, the conveying device 2, the visual positioning device 4, and the inkjet drawing device 5 are identical to the utility patent design of the applicant filed on June 24, 2024, with application number 202421441061.7, and will not be described in detail here.

[0026] Reference Figures 1 to 4 The pressing device 3 includes a drive source mounted on the frame 1, a frame 31 mounted on the frame 1, a drive roller group 32 rotatably mounted on the frame 31 and connected to the output end of the drive source, multiple pressing wire meshes 33 sequentially wound around the drive roller group 32 and arranged in parallel with each other, and a positioning guide member 34 mounted on the frame 31. The multiple pressing wire meshes 33 are respectively limited and passed through the positioning guide member 34.

[0027] The drive roller assembly 32 consists of multiple rectangular drive rollers 32. Multiple pressure wire meshes 33 are arranged in a ring and sequentially wound around the outer surface of the multiple drive rollers. A drive belt 35 is also provided on the multiple drive rollers, and the drive belt 35 is also rectangular and wound around the outer surface of the multiple drive rollers to achieve synchronous rotation of the multiple drive rollers. The drive roller assembly 32 drives the pressure wire meshes 33 to rotate and moves synchronously in the same direction as the conveying surface of the conveying device 2. The pressure wire meshes 33 are arranged above the conveying device 2 and form a conveying channel for conveying materials. The drive source is a synchronous motor assembly, a ball screw assembly, a gear transmission assembly, or a crank-connecting rod transmission assembly.

[0028] Multiple positioning guides 34 are provided and are respectively located at multiple drive rollers; the positioning guides 34 include a positioning plate 341 installed on the frame 31, and multiple positioning slots 342 are sequentially opened on the positioning plate 341 along its length direction, and multiple pressure wire meshes 33 are sequentially arranged in the multiple positioning slots 342.

[0029] Preferably, the two positioning plates 341 above the frame 31 are arranged in an L-shape, and positioning slots 342 are provided on both sides of the positioning plates 341. The two positioning plates 341 above the frame 31 are respectively arranged on the sides of the two drive rollers above the frame 31. The two pressure wire meshes 33 on both sides located on the tangent of the drive rollers form a ring with the positioning plates 341, and the drive rollers are located in the ring.

[0030] The implementation principle is as follows: the material to be drawn is placed sequentially on the conveying device 2. As the conveying device 2 conveys the material, it is positioned within the conveying channel formed by the pressing mesh 33 in the pressing device 3 and the conveying device 2. The pressing mesh 33 fixes and flattens the material to be drawn. The driving source in the pressing device 3 acts on the driving roller group 32, causing multiple pressing meshes 33 to operate parallel and synchronously under the limiting action of the positioning guide 34, so that the conveying device 2 and the pressing meshes 33 move synchronously in the same direction. At this time, the vision positioning device 4 on the frame 1 takes a picture of the material to be drawn in the conveying channel and transmits the picture to the image analysis module of the host.

Finally, the information processing module transmits the electrical signal of the drawing trajectory to the inkjet drawing device 5, so that the inkjet drawing device 5 completes the drawing work in the corresponding zone. It has the effects of automatic drawing, convenient and fast production, high drawing efficiency and low production cost. Example
