Description

Technical Field

[0001] This application relates to the field of line drawing equipment technology, and in particular to an inkjet line drawing machine with adjustable spacing. 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 outline drawn on these lines. Taking shoemaking as an example, a single shoe upper is typically punched out from a roll of leather using a punch press. To ensure even folding and accurate shoe pattern shaping, lines are drawn along the connecting edges of the upper, and the folding is done within the drawn lines to achieve uniformity. A marking machine is an indispensable piece of equipment in shoe manufacturing. Before the advent of marking machines, shoe factories relied on manual marking, which had low accuracy and was prone to errors leading to production deviations. Marking machines, controlled by a computer, can replace manual marking, greatly reducing errors. Furthermore, marking machines can mark multiple pieces of material at once, saving labor costs and manpower.

[0003] Existing line marking machines, such as the Chinese patent with authorization announcement number CN113211999B and publication date August 2, 2022, disclose an online intelligent integrated line marking machine, including a frame and a conveyor belt mounted on the frame. A workpiece fixing device is provided above the conveyor belt, which rolls and presses the workpiece against the conveyor belt, and the workpiece fixing device moves synchronously with the conveyor belt. Along the conveying direction of the conveyor belt, the frame is sequentially equipped with a feeding position, a position positioning and identification device, a printing component, and a receiving position. The feeding position and the receiving position are used for feeding and collecting the workpiece, respectively. The position positioning and identification device is used to locate and identify the position of the object to be printed. The printing component includes multiple sets of printed ink cartridges arranged in an array and a controller for controlling the operation of the printed ink cartridges. The controller is connected to the position positioning and identification device and the printed ink cartridges respectively. The object to be printed fixing device includes several winding rollers and yarns. The winding rollers are linked to the drive rollers of the conveyor belt. The yarns are wound around the winding rollers and are adapted to the conveyor belt for rolling. The winding rollers are provided with several equally spaced winding grooves, and the yarns are movably wound and fixed in the winding grooves.

[0004] In the above-mentioned method, the conveyor belt and the filament move synchronously in the same direction, pressing the substrate against the conveyor belt. The substrate can also continue to move forward with the conveyor belt, thus achieving the purpose of fixing the substrate and moving it relative to the printing ink cartridge to cooperate with the subsequent printing line drawing process. Regarding the above-mentioned related technology, the inventor believes that due to the wide variety of substrates or materials to be printed, and the uneven thickness of the substrates or materials to be printed, the fixed distance between the conveyor belt and the filament in the above-mentioned equipment cannot be well applied to the wide variety of substrates or materials to be printed, thus affecting the applicability of the equipment. Utility Model Content

[0005] This application provides an inkjet line drawing machine with adjustable spacing, which has the effects of automatically completing line drawing, strong applicability, and high line drawing efficiency.

[0006] This application provides a pitch-adjustable inkjet line drawing machine using the following technical solution:

[0007] An adjustable-spacing inkjet line marking machine includes a frame and a conveying device mounted on the frame 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 set of drive rollers rotatably mounted on the frame and connected to the output end of the drive source, and a line marking mesh wound around the drive roller set. The drive roller set drives the line marking mesh to rotate and moves synchronously with the conveying surface of the conveying device in the same direction. The line marking mesh is arranged above the conveying device and forms a conveying channel for conveying materials. An adjustment unit is installed on the frame for adjusting the spacing between the drive rollers in the drive roller set. The adjustment unit is used to adjust the height of the conveying channel.

[0008] Preferably, the adjustment unit includes an adjustment block rotatably connected to the axis of the drive roller in the drive roller group, a fixed block fixedly installed on the frame, and an adjustment component connected between the fixed block and the adjustment block for adjusting the relative position of the adjustment block on the fixed block.

[0009] Preferably, a sliding mounting groove is provided on the fixed block, and the adjusting block is directionally and slidably installed in the sliding mounting groove; the adjusting component includes an adjusting rod rotatably mounted on the frame in the middle, an adjusting bolt connected to one end of the adjusting rod by a threaded rotation, and a pressing block installed on the other end of the adjusting rod. The adjusting bolt passes through the adjusting rod and its end abuts against the frame, and the pressing block is pressed against the adjusting block under the action of the adjusting bolt.

[0010] Preferably, the adjusting component is a second adjusting bolt that is rotatably connected to the fixed block by means of a threaded rotation, and the end of the second adjusting bolt is connected to the adjusting block in a relatively free-rotating connection manner.

[0011] Preferably, the pressing mesh is composed of multiple pressing units arranged in parallel to each other and wound sequentially around the drive roller group; the adjusting block moves relative to the fixed block under the combined action of the adjusting component and the pressing mesh.

[0012] Preferably, the drive roller group consists of multiple drive rollers arranged in a rectangular shape, and the multiple pressing units are arranged in a ring and sequentially wound around the outer surface of the multiple drive rollers.

[0013] Preferably, a synchronous drive belt assembly is also provided on the multiple drive rollers, the synchronous drive belt assembly being rectangular in shape and wound around one side of the multiple drive rollers.

[0014] Preferably, the drive roller assembly consists of four drive rollers arranged in a rectangular shape, and the adjustment unit is symmetrically arranged on both sides of the two drive rollers below the frame.

[0015] In summary, this application includes at least one of the following beneficial technical effects:

[0016] Based on the thickness of the material to be drawn, the spacing between the drive rollers in the drive roller group is adjusted by adjusting the adjustment unit, thereby adjusting the height of the conveying channel to accommodate the pressing and conveying of substrates or materials to be drawn of different thicknesses. The material to be drawn is then placed sequentially on the conveying device. As the conveying device and the pressure screen move synchronously in the same direction, the material to be drawn is conveyed within the conveying channel formed between the pressure screen and the conveying device. The material to be drawn is fixed, flattened, and conveyed through the interaction of the pressure screen. 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, strong applicability, and high drawing efficiency.

[0017] By rotating the adjusting bolt in the adjusting unit, the adjusting rod is rotated relative to the frame, which in turn causes the pressing block to act on the adjusting block. Under the combined action of the adjusting component and the pressure wire mesh, the adjusting block and the fixed block move relative to each other, thereby adjusting the spacing between the driving rollers in the driving roller group, thus realizing the adjustment of the height of the conveying channel.

[0018] The synchronous drive belt is wound in a rectangular shape around one side of multiple drive rollers to achieve the purpose of synchronous rotation of multiple drive rollers;

[0019] By rotating the adjusting bolt one in the adjusting component, the adjusting bolt two and the adjusting block rotate freely, causing the adjusting block to slide relative to the sliding mounting groove of the fixed block, thereby adjusting the spacing between the driving rollers in the driving roller group, thus realizing the adjustment of the height of the conveying channel to suit the pressing and conveying of substrates or materials to be drawn with different thicknesses.

[0027] The present application will be further described in detail below with reference to the accompanying drawings.

[0028] This application discloses an inkjet line drawing machine with adjustable spacing. Example

[0029] Reference Figure 1 , Figure 2 The adjustable spacing inkjet line marking machine includes a frame 1 and a conveying device 2 for conveying materials, a vision positioning device 3 for capturing and uploading the position of the materials on the conveying device 2, a pressing device 4 for fixing and flattening the materials on the conveying device 2, and an inkjet line marking device 5 for marking lines on the materials on the conveying device 2. The inkjet line marking device 5 is located above the conveying device 2 and is electrically connected to the vision positioning device 3.

[0030] Among them, the conveying device 2, the visual positioning device 3, and the inkjet drawing device 5 are identical to the utility patent design of the applicant filed on June 22, 2024, with application number 202421441061.7, and will not be described in detail here.

[0031] Reference Figures 2 to 4 The pressing device 4 includes a drive source 41 mounted on the frame 1, a frame 42 mounted on the frame 1, a drive roller assembly 43 rotatably mounted on the frame 42 and connected to the output end of the drive source 41, and a pressing wire mesh 44 wound around the drive roller assembly 43. The drive source 41 is a synchronous motor assembly, a ball screw assembly, a gear transmission assembly, or a crank connecting rod transmission assembly. The drive roller assembly 43 drives the pressing wire mesh 44 to rotate and moves synchronously with the conveying surface of the conveying device 2 in the same direction. The pressing wire mesh 44 is arranged above the conveying device 2 and forms a conveying channel for conveying materials.

[0032] Reference Figures 2 to 4 The drive roller group 43 is composed of multiple drive roller groups 43 arranged in a rectangular shape. In this scheme, the drive roller group 43 is preferably composed of four drive roller groups 43 arranged in a rectangular shape. A synchronous drive belt group 45 is also provided on the four drive rollers. The synchronous drive belt group 45 is wrapped around one side of the four drive rollers in a rectangular shape to achieve the purpose of synchronous rotation of multiple drive rollers. The pressure wire mesh 44 is composed of multiple pressure wire units arranged in parallel to each other and wound around multiple drive rollers in sequence. The multiple pressure wire units are wound around the outer surface of multiple drive rollers in a ring shape.

[0033] An adjustment unit 46 is installed on the frame 42 for adjusting the spacing between the drive rollers in the drive roller group 43. The adjustment unit 46 is used to adjust the height of the conveying channel to accommodate the pressing and conveying of substrates or materials to be drawn with different thicknesses.

[0034] Adjustment units 46 are symmetrically arranged on both sides of the two drive rollers below the frame 42. Each adjustment unit 46 includes an adjustment block 461 rotatably connected to both sides of the drive roller on its axis, a fixed block 462 fixedly installed on the frame 42, and an adjustment component 463 connected between the fixed block 462 and the adjustment block 461 for adjusting the relative position of the adjustment block 461 on the fixed block 462. The two ends of the drive roller are rotatably connected to the adjustment block 461 through a bearing 468. Under the combined action of the adjustment component 463 and the pressure wire mesh 44, the relative movement between the adjustment block 461 and the fixed block 462 is realized.

[0035] A sliding mounting groove 4621 is provided on the fixed block 462, and the adjusting block 461 is slidably installed in the sliding mounting groove 4621 in the vertical direction; the adjusting component 463 includes an adjusting rod 464 rotatably mounted on the frame 42 in the middle, an adjusting bolt 465 threadedly connected to one end of the adjusting rod 464, and a pressing block 466 installed on the other end of the adjusting rod 464. The end of the pressing block 466 is preferably spherical; the adjusting bolt 465 is threadedly inserted into the adjusting rod 464 and its end abuts against the frame 42, and the pressing block 466 is pressed against the adjusting block 461 under the action of the adjusting bolt 465.

[0036] The implementation principle is as follows: According to the thickness of the material to be drawn, by rotating the adjusting bolt 465 in the adjusting unit 46, the adjusting rod 464 is rotated relative to the frame 42, which causes the pressing block 466 to act on the adjusting block 461. Under the combined action of the adjusting component 463 and the pressing mesh 44, the adjusting block 461 and the fixed block 462 move relative to each other, thereby adjusting the spacing between the driving rollers in the driving roller group 43, thus realizing the adjustment of the height of the conveying channel, so as to be suitable for pressing and conveying substrates or materials to be drawn with different thicknesses.

[0037] During operation, the material to be drawn is placed sequentially on the conveyor 2. As the conveyor 2 and the pressure mesh 44 move synchronously along the same plane, the material to be drawn is transported within the conveying channel formed between the pressure mesh 44 and the conveyor 2. The material to be drawn is fixed, flattened, and transported through the interaction of the pressure mesh 44. At this time, the vision positioning device 3 located 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. The image analysis module calculates the drawing trajectory according to the shape and placement position of the material to be drawn. 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, strong applicability, and high drawing efficiency. Example

[0038] An inkjet line drawing machine with adjustable spacing, combined with Figure 3 , Figure 4 , Figure 6The difference from Embodiment 1 is that the adjusting member 463 is an adjusting bolt 467 that is screwed to the fixed block 462. The end of the adjusting bolt 467 and the adjusting block 461 are connected in a relatively free-spinning manner. According to the thickness of the material to be drawn, by rotating the adjusting bolt 465 in the adjusting member 463, the adjusting bolt 467 and the adjusting block 461 are free-spinning, causing the adjusting block 461 to slide relative to the sliding mounting groove 4621 of the fixed block 462. This allows the spacing between the driving rollers in the driving roller group 43 to be adjusted, thereby realizing the adjustment of the height of the conveying channel to be suitable for pressing and conveying substrates or materials to be drawn of different thicknesses.

[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
