Description

Technical Field

[0001] This application relates to the field of line marking machine technology, and in particular to an inkjet line marking machine that is clogging-resistant and easy to clean. 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 aforementioned ink cartridge, the ink cartridge is fixedly mounted on the frame. When the machine is not in operation, because the ink cartridge is usually installed higher than the printhead, the inkjet system is affected by gravity, and the ink can naturally flow from the secondary ink cartridge into the printhead. The ink located at the printhead is prone to drying when in contact with air, causing the printhead nozzles to become clogged. When it is needed to be used again, the main ink cartridge needs to be disassembled and the printhead nozzles need to be cleared with scissors or a needle, which greatly affects the working efficiency of the line drawing equipment. Sometimes, the operator may mistakenly believe that the main ink cartridge is empty and directly replace the ink cartridge, wasting materials and increasing production costs. Utility Model Content

[0005] This application provides an inkjet line printer that is easy to clean and prevents clogging, which has the effects of being easy to clean, reducing the frequency of ink supply system clogging, and improving the inkjet efficiency of the ink supply system.

[0006] The inkjet line marking machine that is clogging-resistant and easy to clean provided in this application adopts the following technical solution:

[0007] An anti-clogging and easy-to-clean 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 inkjet line marking device includes a support plate mounted above the conveying surface of the conveying device and an inkjet system mounted on the support plate. The inkjet system is electrically connected to the visual positioning device. One side of the support plate is hinged to the frame so that the support plate can be flipped onto the frame. An opening and closing locking device is installed on the other side of the support plate to lock the support plate onto the frame.

[0008] Preferably, the opening and closing locking component includes a fixed base mounted on the frame, a connecting base mounted on the support plate, and a fixing element installed between the fixed base and the connecting base for fixing or disassembling the two.

[0009] Preferably, the fixing element is a pin, and both the fixing seat and the connecting seat have insertion holes. When the support plate is erected parallel above the conveying surface of the conveying device, the insertion holes on the fixing seat and the connecting seat are located on the same axis, and the pin passes through the insertion hole to fix the fixing seat and the connecting seat.

[0010] Preferably, a handle is provided on the support plate.

[0011] Preferably, the inkjet drawing device further includes a protective cover slidably mounted on the frame to protect the inkjet system.

[0012] Preferably, the inkjet drawing device is connected to a lifting unit for driving the inkjet system to move up and down relative to the inkjet working surface.

[0013] Preferably, the lifting unit includes a reset spring, a cylinder mounted on the frame, and a lifting plate slidably mounted on the frame; one end of the lifting plate is connected to a fixed base, the reset spring is connected between the frame and the lifting plate, the drive rod of the cylinder can act on the lifting plate, and the lifting plate is raised and lowered on the frame under the interaction of the reset spring and the cylinder.

[0014] Preferably, it also includes a pad with an elastic pad provided on the pad, and when the inkjet system is located above the pad, the printhead of the inkjet system abuts against the elastic pad.

[0015] Preferably, the pad is slidably mounted on the frame, and the pad is located above the conveying surface of the conveying device.

[0016] In summary, this application includes at least one of the following beneficial technical effects:

[0017] By operating the locking mechanism, the support plate is loosened from the frame, and then an action is applied to one side of the support plate to flip it over. This allows for wiping, cleaning, or maintenance of the printheads in the inkjet system on the support plate, facilitating quick cleaning and maintenance of the inkjet system and reducing the frequency of ink supply system clogging. By placing the material to be drawn on the conveyor device sequentially, and with the conveying surfaces of the conveyor and the pressing device moving synchronously in the same direction, the material is transported within the conveying channel formed between the pressing and conveying devices. At this time, a vision positioning device on the frame photographs the material in the conveying channel, and the inkjet drawing device then completes the drawing within the corresponding zone. This method features automatic drawing, convenient and fast production, strong applicability, and high drawing efficiency.

[0018] By pulling the pin out from between the fixed seat and the connecting seat, and then flipping the support plate, the printhead in the inkjet system can be wiped clean or repaired. This facilitates quick cleaning or repair of the inkjet system and reduces the frequency of ink supply system clogging.

[0019] A handle is fixedly installed on one side of the support plate to facilitate the flipping of the support plate; at the same time, a protective cover for protecting the inkjet system is slidably installed on the frame. When the inkjet system is working, the protective cover covers the outer perimeter of the inkjet system, improving the protection of the inkjet system in the inkjet drawing device.

[0020] By connecting a lifting unit to the inkjet marking device, which drives the inkjet system to rise and fall relative to the inkjet working surface; and by changing the interval height between the inkjet system and the conveying surface of the conveying device through the interaction of the return spring and the cylinder, the applicability of the inkjet marking device to marking lines on materials of different thicknesses is improved.

[0021] When the inkjet system stops working, the support plate is lowered by the lifting unit, so that the printhead of the inkjet system comes into contact with the elastic pad on the pad plate. The elastic pad is then sealed to the printhead of the inkjet system, isolating the ink at the printhead from contact with air, reducing the frequency of ink supply system clogging, so that the inkjet line printer can work smoothly next time, and improving the inkjet efficiency of the ink supply system.

[0028] The present application will be further described in detail below with reference to the accompanying drawings.

[0029] This application discloses an inkjet line drawing machine that is clogging-resistant and easy to clean.

[0030] Reference Figure 1 , Figure 2The anti-clogging and easy-to-clean inkjet line marking machine includes a frame 1 and a conveying device 2 for conveying materials, a visual 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 conveying surface of the conveying device 2 and the conveying surface of the pressing device 4 move synchronously in the same direction. The inkjet line marking device 5 is located above the conveying device 2 and is electrically connected to the visual positioning device 3.

[0031] Among them, the conveying device 2, the visual positioning device 3, and the pressing device 4 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.

[0032] Reference Figures 2 to 4 The inkjet drawing device 5 includes a support plate 51 mounted above the conveying surface of the conveying device 2 and an inkjet system 52 mounted on the support plate 51. The inkjet system 52 is electrically connected to the vision positioning device 3. One side of the support plate 51 is hinged to the frame 1 so that the support plate 51 can be flipped on the frame 1. On the other side of the support plate 51, an opening and closing locking member 53 is installed to lock the support plate 51 on the frame 1.

[0033] Reference Figures 3 to 5 The locking and unlocking mechanism 53 includes a fixed base 531 mounted on the frame 1, a connecting base 532 mounted on the support plate 51, and a fastener 533 installed between the fixed base 531 and the connecting base 532 for fixing or disassembling the two. In this solution, the fastener 533 is preferably a pin. Both the fixed base 531 and the connecting base 532 are provided with insertion holes. When the support plate 51 is mounted parallel above the conveying surface of the conveying device 2, the insertion holes on the fixed base 531 and the connecting base 532 are located on the same axis and parallel to the conveying surface of the conveying device 2. The pin passes through the insertion hole to fix the fixed base 531 and the connecting base 532.

[0034] The fastener 533 can also be a bolt, which can be used to fix or disassemble the fixed seat 531 and the connecting seat 532 through a threaded rotation connection.

[0035] When it is necessary to wipe, clean or repair the printhead in the inkjet system 52, the pin can be pulled out from between the fixed seat 531 and the connecting seat 532, and the printhead in the inkjet system 52 can be wiped, cleaned or repaired by flipping the support plate 51. This facilitates quick cleaning or repair of the inkjet system 52 and reduces the frequency of ink supply system clogging.

[0036] To facilitate the flipping of the support plate 51, a handle 534 is fixedly installed on one side of the support plate 51; at the same time, to improve the protection of the inkjet system 52 in the inkjet drawing device 5, a protective cover 54 for protecting the inkjet system 52 is slidably installed on the frame 1; when the inkjet system 52 is working, the protective cover 54 covers the outer periphery of the inkjet system 52.

[0037] To improve the ability of the inkjet marking device 5 to mark lines on materials of different thicknesses, the inkjet marking device 5 is connected to a lifting unit 55 for driving the inkjet system 52 to rise and fall relative to the inkjet working surface; the two lifting units 55 are symmetrically arranged on both sides of the support plate 51.

[0038] The lifting unit 55 includes a reset spring 551, a cylinder 552 mounted on the frame 1, and a lifting plate 553 slidably mounted on the frame 1. One end of the lifting plate 553 is connected to the fixed seat 531. The reset spring 551 is connected between the frame 1 and the lifting plate 553. The drive rod of the cylinder 552 can act on the lifting plate 553. The lifting plate 553 moves up and down on the frame 1 under the interaction of the reset spring 551 and the cylinder 552. The interval height between the inkjet system 52 and the conveying surface of the conveying device 2 in the inkjet drawing device 5 is changed by the interaction of the reset spring 551 and the cylinder 552, thereby improving the applicability of the inkjet drawing device 5 to drawing lines on materials of different thicknesses.

[0039] Furthermore, in order to reduce the frequency of clogging in the ink supply system of the inkjet drawing device 5, a pad 56 is slidably installed on the frame 1, and the pad 56 is driven by a cylinder to reciprocate above the conveying surface of the conveying device 2; an elastic pad 561 is provided on the pad 56, and the elastic pad 561 is a gasket made of a sealing material with a certain elasticity, such as a rubber pad or a silicone pad.

[0040] When the inkjet system 52 is above the pad 56, the support plate 51 is lowered by the lifting unit 55, so that the printhead of the inkjet system 52 contacts the elastic pad 561 on the pad 56. This achieves a seal between the elastic pad 561 and the printhead of the inkjet system 52, isolating the ink at the printhead from contact with air, reducing the frequency of ink supply system clogging, and ensuring smooth operation of the inkjet line printer next time, thus improving the inkjet efficiency of the ink supply system. When the inkjet line printer restarts, the drive rod of the cylinder 552 acts on the lifting plate 553, causing the support plate 51 to move upward and the pad 56 to slide out from under the inkjet system 52, so that the inkjet line printer 5 can work normally.

[0041] The implementation principle is as follows: During operation, the material to be drawn is placed sequentially on the conveying device 2. As the conveying surface of the conveying device 2 and the conveying surface of the pressing device 4 move synchronously in the same direction, the material to be drawn is conveyed in the conveying channel formed between the pressing device 4 and the conveying device 2. At this time, the vision positioning device 3 located on the frame 1 takes pictures of the material to be drawn in the conveying channel and transmits the captured image 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.

[0042] When the inkjet system 52 of the inkjet marking device 5 needs to be wiped, cleaned, or repaired, the fixing member 533 in the locking mechanism 53 is operated to loosen the fixing seat 531 and the connecting seat 532. Then, the action on one side of the support plate 51 causes the support plate 51 to flip, allowing the printheads in the inkjet system 52 on the support plate 51 to be wiped, cleaned, or repaired. This facilitates quick cleaning or repair of the inkjet system 52 and reduces the frequency of ink supply system clogging. At the same time, when the inkjet system 52 stops working, the lifting unit 55 controls the support plate 51 to descend, causing the printheads of the inkjet system 52 to come into contact with the elastic pad 561. This achieves a seal between the elastic pad 561 and the printheads of the inkjet system 52, isolating the ink at the printheads from contact with air, reducing the frequency of ink supply system clogging, and ensuring smooth operation of the inkjet marking machine next time, thus improving the inkjet efficiency of the ink supply system.

[0043] 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.
