Description

Technical Field

[0001] This application relates to the field of line marking machine technology, and in particular to a feeding device and a visual inkjet line marking machine using the feeding device. 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 equipment for automatic line drawing typically uses manual material feeding. For example, Chinese Patent No. CN222661732U, published on March 25, 2025, discloses an automated vision inkjet line drawing machine, which includes a frame. On the frame are mounted a conveying device for transporting materials, a vision positioning device for capturing and uploading the position of the material on the conveying device, a pressing device for fixing and flattening the material on the conveying device, and an inkjet line drawing device for drawing lines on the material on the conveying device. The inkjet line drawing device is located above the conveying device and is electrically connected to the vision positioning device. The pressing device includes a drive source mounted on the frame, a drive roller assembly connected to the output end of the drive source, and a pressing mesh wound around the drive roller assembly. The drive roller assembly drives the pressing mesh to rotate and moves synchronously in the same direction as the conveying surface of the conveying device. The pressing mesh is arranged above the conveying device and forms a conveying channel for transporting materials.

[0004] In operation, the above-mentioned device requires a worker to be stationed on one side of the conveyor to place the materials to be marked on the conveyor in sequence. As the conveyor transports the materials, it achieves the function of continuous feeding. This device greatly increases labor costs and is inefficient. Utility Model Content

[0008] Preferably, the material distribution unit includes a material distribution mounting frame erected on the base and a material distribution baffle installed on the material distribution mounting frame. The material distribution baffle is located above the conveying unit and forms a material distribution gap with the conveying surface of the conveying unit.

[0014] Preferably, it further includes a pressing unit for conveying a single material on the conveying surface of the auxiliary conveying unit; the pressing unit includes a pressing roller, a fixed shaft mounted on a base, and an elastic element installed between the fixed shaft and the pressing roller. The pressing roller contacts the conveying surface of the conveying unit under the action of the elastic element and rotates, and the material is conveyed between the pressing roller and the conveying surface of the conveying unit.

[0015] Preferably, the elastic element includes a reset spring and a pressure arm rotatably mounted on a fixed shaft at one end, and the pressure roller is rotatably mounted on the other end of the pressure arm; the reset spring acts on the pressure arm to cause the pressure roller to abut against the conveying surface of the conveying unit, thereby realizing the passive rotation of the pressure roller.

[0016] The second application provides a vision inkjet line drawing machine, which features automatic material arrangement and feeding, automatic line drawing, convenient and fast production, high line drawing efficiency, and low production cost.

[0017] The visual inkjet line drawing machine provided in this application adopts the following technical solution:

[0018] The device includes a frame, a feeding device as described above, 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 drawing device for drawing lines on the materials on the conveying device. The inkjet drawing device is located above the conveying device and is electrically connected to the visual positioning device. The feeding device is arranged on the feeding side of the conveying device and is used to sequentially convey materials onto the conveying device.

[0019] In summary, this application includes at least one of the following beneficial technical effects:

[0020] By placing the stacked material in the feeding unit, the material at the bottom of the stacked material in the feeding unit is fed sequentially by the conveying unit under the interaction of the conveying unit and the distributing unit. During the conveying process, the pressing unit helps to stabilize the conveying of individual materials on the conveying surface of the conveying unit, which has the effect of improving feeding efficiency and reducing labor costs.

[0021] By rotating the adjusting bolt of the discharge baffle, the position of the discharge baffle on the base can be changed, thereby adjusting the size of the limiting area so that the limiting area can be used for material stacking of different sizes.

[0022] By installing limit rods on the material distribution frame, a guide area is formed between the multiple limit rods and the material distribution baffle to guide the stacked materials. The material distribution baffle is tilted towards one end of the conveying unit in the conveying direction of the conveying unit. Through the action of the conveying unit, the materials under the stacked materials are placed in a locomotive shape, which better allows the bottom material to be fed one by one sequentially with the conveying unit.

[0023] A height adjustment component is connected to the material distribution baffle to adjust the height of the material distribution gap. By rotating the height adjustment component, the material distribution baffle can be moved up and down, thereby adjusting the height of the material distribution gap. This allows for the distribution, feeding, and conveying of materials of different thicknesses.

[0024] By connecting a pre-tension spring between the two adjusting arms, the ends of the width adjusting parts on the two rotating arms are always in contact with the mounting frame under the action of the pre-tension spring; at the same time, the distance between the two limiting rods can be adjusted by rotating the width adjusting parts, thereby adjusting the size of the guide area, thus improving the limiting stacking of stacked materials and the applicability of materials of different sizes;

[0025] By stacking the materials to be drawn on the feeding device, the materials are sequentially and individually conveyed to the conveying device. The materials to be drawn are located in the conveying channel formed by the pressing device and the conveying device. The conveying device and the pressing device move synchronously in the same direction. At this time, the vision positioning device on the frame takes a picture of the materials to be drawn in the conveying channel, and then the inkjet drawing device completes the drawing work in the corresponding zone. It has the advantages of automatic material arrangement and feeding, automatic drawing, convenient and fast production, high drawing efficiency and low production cost. Attached Figure Description

[0033] The present application will be further described in detail below with reference to the accompanying drawings. Example 1

[0034] This application discloses a feeding device.

[0035] Reference Figure 1 , Figure 2The feeding device 800 includes a base 1, a conveying unit 2, a distributing unit 3, a discharging unit 4, and a pressing unit 5 installed on the base 1; the discharging unit 4 is located above the conveying unit 2 for stacking materials; the distributing unit 3 is located on one side of the conveying direction of the conveying unit 2 and distributes the materials at the discharging unit 4 one by one, so that the materials are sequentially conveyed on the conveying unit 2; the pressing unit 5 is used to assist in stabilizing the conveying of individual materials on the conveying surface of the conveying unit 2.

[0036] Reference Figures 2 to 4 The conveying unit 2 is a motor belt conveyor structure, which is an existing technology and will not be described in detail here. The unloading unit 4 includes unloading baffles 41 installed on the base 1 and located on both sides of the conveyor belt of the conveying unit 2. A limiting area 42 for limiting the placement of stacked materials is formed between the multiple unloading baffles 41. At the same time, an adjusting bolt 43 is rotatably connected to at least one of the unloading baffles 41, and a fixing block 44 is provided on the base 1. The adjusting bolt 43 is threadedly rotatably connected to the fixing block 44. By adjusting the rotation of the adjusting bolt 43, the position of the unloading baffle 41 on the base 1 can be changed, and the size of the limiting area 42 can be adjusted so that the limiting area 42 is suitable for stacking materials of different sizes.

[0037] The material distribution unit 3 includes a material distribution mounting frame 31 mounted on the base 1 and a material distribution baffle 32 mounted on the material distribution mounting frame 31. The material distribution baffle 32 is located above the conveying surface in the conveying unit 2 and forms a material distribution gap 33 between it and the conveying surface of the conveying unit 2. The material distribution gap 33 is greater than the thickness of a single material and less than the thickness of two stacked materials.

[0038] To improve the flatness of the material stack in the limiting area 42 and to guide and feed the material, limiting rods 34 are provided on the material distribution mounting frame 31. A guiding area 35 for guiding the stacked material is formed between the multiple limiting rods 34 and the material distribution baffle 32. Preferably, two limiting rods 34 are arranged on both sides of the material distribution baffle 32. The limiting area 42 is formed between the multiple material discharge baffles 41 and the guiding area 35.

[0039] To facilitate the stable sequential conveying of stacked materials within the limiting area 42, the end of the material distribution baffle 32 facing the conveying unit 2 is set as an inclined end 321, and the inclined direction of the inclined end 321 is arranged in the conveying direction of the conveying unit 2; through the action of the conveying unit 2, the materials below the stacked materials are placed in a locomotive shape, so that the bottommost materials are fed sequentially with the conveying unit 2.

[0040] Reference Figures 2 to 4To further improve the applicability of the feeding unit 4 to materials, a height adjustment component 36 for adjusting the height of the material distribution gap 33 is connected to the material distribution baffle 32. The height adjustment component 36 is a bolt-adjustable structure; that is, an extension plate 322 is fixedly connected to the material distribution baffle 32, and the height adjustment component 36 is threadedly rotatably connected to the extension plate 322. The other end of the height adjustment component 36 is idling and mounted on the material distribution mounting frame 31. By rotating the height adjustment component 36, the material distribution baffle 32 can be moved up and down, thereby adjusting the height of the material distribution gap 33. This allows for the feeding and conveying of materials of different thicknesses.

[0041] Meanwhile, two limiting rods 34 are respectively fixedly connected to adjusting arms 37, and the other end of each adjusting arm 37 is rotatably mounted on the material distribution mounting frame 31. Each adjusting arm 37 is provided with a width adjusting component 38 for adjusting the size of the guide area 35. The width adjusting component 38 is a bolt adjustment structure; that is, the height adjusting component 36 is threaded through the rotating arm, and the end of the height adjusting component 36 abuts against the mounting frame. A pre-tension spring 39 is connected between the two adjusting arms 37. Under the action of the pre-tension spring 39, the ends of the width adjusting components 38 on the two rotating arms are always abutting against the mounting frame. At the same time, by rotating the width adjusting component 38, the distance between the two limiting rods 34 can be adjusted, thereby adjusting the size of the guide area 35, thus improving the limiting stacking of stacked materials and the applicability of materials of different sizes.

[0042] Reference Figures 2 to 4 The pressing unit 5 includes a pressing roller 51, a fixed shaft 52 mounted on the base 1, a limiting plate 53 mounted on the fixed shaft 52, and an elastic element connecting the fixed shaft 52 and the pressing roller 51. The limiting plate 53 is located above the conveying surface of the conveyor belt of the conveying unit 2 and is used to prevent the conveying unit 2 from tilting when conveying materials. The two pressing rollers 51 are arranged along the conveying direction of the conveying unit 2 and are located at both ends of the limiting plate 53. Under the action of the elastic element, the pressing rollers 51 contact the conveying surface of the conveyor belt of the conveying unit 2 and rotate, and the material is conveyed between the pressing rollers 51 and the conveying surface of the conveying unit 2.

[0043] The elastic element includes a reset spring 54 and a pressure arm 55 rotatably mounted on a fixed shaft 52 at one end. The two pressure arms 55 are arranged on both sides of the fixed shaft 52 and form an included angle. Two pressure rollers 51 are rotatably mounted on the other end of the two pressure arms 55 respectively. The reset spring 54 acts between the two pressure arms 55 and causes the pressure rollers 51 to abut against the belt conveyor surface of the conveyor unit 2, thereby realizing the passive rotation of the pressure rollers 51.

[0044] The implementation principle is as follows: Based on the area and thickness of the material to be marked, the size of the limiting area 42 formed between the feeding baffles 41 is adjusted by operating the adjusting bolts 43 to accommodate material stacking of different areas. The height adjustment component 36 at the distributing unit 3 is adjusted to regulate the height of the distributing gap 33, accommodating material feeding and conveying of materials of different thicknesses. The width adjustment component 38 allows for adjustment of the size of the guiding area 35, thereby improving the limiting stacking of materials and its applicability to materials of different sizes. By placing the stacked material in the feeding unit 4, and conveying it via the conveyor belt of the conveyor unit 2, the interaction between the conveyor unit 2 and the distributing unit 3 causes the lowest material in the limiting area 42 to be sequentially fed by the conveyor unit 2. During conveying, the pressing unit 5 assists in stabilizing the conveying of individual materials on the conveying surface of the conveyor unit 2, thus improving feeding efficiency and reducing labor costs.

The inkjet line drawing device 500 is located above the conveying device 200 and is electrically connected to the visual positioning device 300. Multiple feeding devices 800 can be configured and arranged side-by-side on the feeding side of the conveying device 200 to sequentially convey materials onto the conveying device 200. A discharge conveyor belt 600 is arranged on the discharge side of the conveying device 200, and a receiving rack 700 is arranged on the side of the discharge conveyor belt 600 away from the conveying device 200.

[0047] The implementation principle is as follows: the materials to be drawn are stacked on the feeding device 800 to be individually conveyed to the conveying device 200. The materials to be drawn are located in the conveying channel formed by the pressing device 400 and the conveying device 200. The conveying device 200 and the pressing device 400 move synchronously in the same direction. At this time, the vision positioning device 300 on the frame 100 takes pictures of the materials to be drawn in the conveying channel, and then the inkjet drawing device 500 completes the drawing work in the corresponding zone.
