Description

Technical Field

[0001] The invention belongs to the technical field of printers, and in particular to a substrate printing track device and a control system of a substrate printer. Background Art

[0002] A printer is one of the output devices of a computer, used to print the results of computer processing on relevant media. There are three indicators to measure the quality of a printer: print resolution, print speed and noise. There are many types of printers. According to whether the printing element has an impact action on the paper, they are divided into impact printers and non-impact printers. According to the structure of printed characters, they are divided into full-width character printers and dot matrix character printers. According to the way a line of characters is formed on paper, they are divided into string printers and line printers. In order to meet production needs and production automation processes, traditional static printers require manual loading and unloading, which consumes a lot of human resources. Therefore, when performing assembly line processing, substrate printers become the first choice.

[0003] When a substrate printer prints on the outer surface of paper or board, it needs to rely on its own set trajectory, that is, the substrate itself moves in a directional manner to cover the entire printing plane to achieve printing. However, certain problems may arise in the actual printing process. For example, when the printer head scans the printing surface, because the material to be printed is not completely attached to the bottom surface, during the movement of the printer head, the friction between the head and the printing surface will pull the material to move. Multiple times will result in large deviations, which will cause the printing work to be obstructed or the printed product to be completely unqualified due to errors. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention solves the technical problems by adopting the following technical solutions: a substrate printing track device of a substrate printer, comprising a transport conveyor belt, the outside of which is provided with side rollers, the number of which is two, and the outer surfaces of the side rollers are rotatably connected to the inner wall of the transport conveyor belt, the front and rear sides of the lower part of the outer surface of the side rollers are rotatably connected to a main motor through a friction sleeve, the lower part of the outer surface of the main motor casing is fixedly connected to a bottom support platform; a printing head, the lower part of the outer surface of the printing head is slidably connected to the upper surface of the transport conveyor belt, The front and rear sides of the outer surface of the printing end are symmetrically provided with emitting lamp heads, the upper surface of the printing end is evenly provided with hollow connecting rods, and the upper part of the inner wall of the hollow connecting rod is fixedly connected to a pressurized fixing plate through an air pipe; when the device is used for printing, after the plate or paper to be printed is placed on the left side of the transport conveyor belt, the output shaft of the main motor rotates, and the side rollers on both sides are rotated clockwise through the friction rotating sleeve, thereby rotating the transport conveyor belt clockwise, and the material located on the top is transported from left to right until the material is transported to the middle of the friction rotating sleeve, and the transportation is stopped to start printing.

[0005] The top of the guide rail is symmetrically provided with a guide rail at the front and rear sides of the axis center of the outer surface of the bottom support platform, and the top of the guide rail is symmetrically provided with a bent connecting rod, and the top of the bent connecting rod is fixedly connected with an air guide plate, and the upper surface of the air guide plate is symmetrically provided with a plug-in block; the bottom end of the outer surface of the bent connecting rod is fixedly connected with a fixed gear sleeve, and the upper and lower sides of the outer surface of the fixed gear sleeve are clamped with a filling slider through clamping teeth, and an auxiliary pulley is rotatably connected to the axis center of the inner wall of the filling slider, and the inner wall of the fixed gear sleeve is provided with a threaded groove, and a threaded rotating rod is threadedly connected to a side of the inner wall of the fixed gear sleeve close to the bottom support platform through the threaded groove, and the threaded rotating rod is fixedly connected to a torque motor at one end away from the inner wall of the fixed gear sleeve, and a transmission arm is rotatably connected to the side of the outer surface of the torque motor, and the bottom end of the transmission arm is fixedly connected to the control telescopic rod. Before printing, the device needs to be powered on and started. At this time, the fixed rotating sleeves on the front and rear sides of the printing end are rotated to a horizontal state. At this time, the emitting lamp head is facing the translucent lamp tube below. After the side branch fixing plate receives the light sensor, the torque motors on both sides are started through the inner guide tube, so that the device starts to fix the material, controls the extension of both ends of the telescopic rod, and pushes the bottom end of the transmission arm to both sides. At this time, the transmission arm gradually changes from a bent state to a vertical state, and then pushes the torque motor upward. At this time, the torque motor pulls the bent connecting rod to rise horizontally through the threaded rotating rod, so that the plug-in card block on the upper surface of the air guide plate is directly inserted into the cross-sectional through groove of the transport conveyor belt.

[0006] Preferably, the inner wall of the transport conveyor belt is evenly provided with transverse through grooves, the number of the bent connecting rods is four, the top ends of the bent connecting rods extend to the interior of the transport conveyor belt, and the outer surface of the plug-in card block is slidably connected to the inner wall of the transport conveyor belt through the transverse through grooves. If the middle material is a plate, and the four plug-in blocks inserted into the conveyor belt are not sufficient to clamp the outer surface of the plate, at this time, the output shaft of the torque motor controls the threaded rotating rod to rotate clockwise, and when the threaded rotating rod rotates clockwise, it will be inserted into the interior of the fixed gear sleeve along the threaded groove on the inner wall of the fixed gear sleeve. However, because the fixed gear sleeve cannot be twisted under the blocking effect of the filling slider, and the torque motor cannot move to one side of the fixed gear sleeve, the fixed gear sleeve is pulled to one side of the torque motor, so the bent connecting rods on the front and rear sides begin to approach each other, and the plug-in blocks slide close to each other along the cross-sectional through groove on the inner wall of the conveyor belt, thereby clamping the plate in the middle. At this time, the upper surface of the plate is scanned and sprayed back and forth by the printing end, and the plate will not move relative to each other. After processing is completed, the clamping effect of the plug-in block is released, and the air guide plate is lowered. At this time, the plug-in block is detached from the inner wall of the conveyor belt, and the conveyor belt is started again for transportation to obtain the processed product.

[0007] Preferably, the number of the emitting lamp heads is two, the outer surface of the emitting lamp head is sleeved with a fixed rotating sleeve, and the upper part of the outer surface of the fixed rotating sleeve is rotatably connected to the axis of the outer surface of the printing end through a rotating shaft, the side branch fixing plate and the emitting lamp head are both at the same mid-plane, and the end of the inner guide tube close to the bottom support table is fixedly connected to the torque motor terminals on both sides through elastic wires. The device flexibly controls the movement of the air guide plate and the plug-in card block through the relevant structure inside the bottom support table, so that the object moved to the middle of the transport conveyor belt can be fixed in the middle of the transport conveyor belt. Compared with the traditional card rack fixation, the device does not need to use a card rack to perform a separate fixation work for each plate or paper, thereby avoiding the redundant process of clamping and unloading, and is convenient to use, saving the purchase cost of the card rack. At the same time, in the process of long-line transportation, the device can directly transport the printed products to the next work location, thereby omitting the handling work and improving production efficiency.

[0008] Preferably, the outer surface of the torque motor housing is slidably connected to the inner wall of the bottom support platform, the outer surface of the threaded rotating rod is slidably connected to the inner wall of the bottom support platform through a vertical slide groove, and the outer surface of the filling slide is slidably connected to the inner wall of the guide slide rail through an auxiliary pulley. The device can transport the materials to be processed to the printing end in the middle for printing through a conveyor belt. If it is a hard material such as a printing plate, the plate can be reinforced by plug-in blocks on the front and rear sides to prevent the outer surface of the plate from generating relative friction with the printing end during the printing process, resulting in the problem of random sliding of the plate, thereby avoiding the problem of obstruction of printing work or the problem of completely unqualified printed products due to errors.

[0009] Preferably, the plug-in card block includes an inner slider, the top of the inner slider is fixedly connected to a top fixing frame, and extension sliders are symmetrically arranged on both sides of the inner wall of the top fixing frame, the lower surface of the inner slider is fixedly connected to the lower part of the inner wall of the plug-in card block through a connecting spring, the upper part of the inner wall of the top fixing frame is fixedly connected to the inner wall of the extension slider through a spring belt, and the elastic coefficient of the connecting spring is smaller than the elastic coefficient of the spring belt. If printing is done on paper materials, the paper cannot be fixed by the mutual clamping effect of the front and rear plug-in blocks. At this time, it is necessary to start the air guide plate after the plug-in block is inserted into the cross-sectional through-slot of the transport conveyor belt. The air guide plate inflates the interior of the plug-in block. Since the elastic coefficient of the connecting spring is smaller than the elastic coefficient of the spring belt, when the pressure inside the plug-in block increases, the connecting spring is first stretched. At this time, the inner slider rises along the inner wall of the plug-in block, allowing the top fixed frame to pass through the cross-sectional through-slot of the transport conveyor belt. Subsequently, the extended sliders on both sides begin to slide out from the inner wall of the top fixed frame under the action of pressure, and the limited length of the top fixed frame is stretched. Then, the bent connecting rod is slid downward along the inner wall of the guide rail. At this time, the lower surfaces of the extended sliders extending on both sides just clamp the upper surface of the paper and the upper surface of the transport conveyor belt, thereby fixing the paper. If printing is done on paper materials, the paper cannot be fixed by clamping the front and rear plug-in blocks together. In this case, the extended sliders extending from both sides can be used to press the upper surface of the paper, so that the paper cannot slide relative to each other during the printing process, thereby fixing the paper. The paper is pressed at the corners, and even if indentations occur, they can be eliminated by cutting the borders, thereby ensuring the aesthetics of the finished paper.

[0010] Preferably, the printing end includes an inkjet, a movable pulley is fixedly connected to the upper surface of the inkjet, a control power box is symmetrically arranged on the left and right sides of the inner wall of the printing end, force blocks are symmetrically arranged on the front and rear ends of the control power box, a solid push rod is fixedly connected to the top of the force block away from the control power box, and a fixed hollow tube is slidably connected to the side of the solid push rod away from the force block, and a folding tube is fixedly connected to one end of the fixed hollow tube away from the solid push rod. When the inkjet of the device moves, it will squeeze each other through the suction cup and the end of the folding tube. At this time, the folding tube on the squeezed side will fill the gas into the interior of the fixed hollow tube, and the solid push rod on the other side of the fixed hollow tube will begin to slide in the opposite direction along the inner wall of the fixed hollow tube under the action of pressure, thereby pushing the force block to slide along the inner wall of the force block. At this time, the insulating plate pulls the conductive plate to slide out of the control power box, and the fixed batteries on both sides of the control power box cannot be powered after being disconnected, so the moving pulley is immediately powered off at this time, and the inkjet starts to decelerate under the action of the resistance of the folding tube. When the inkjet stops moving, the compressed folding tube begins to push back to the center position of the inner wall of the printing end, and the conductive plate is reinserted into the control power box, and the fixed batteries on both sides power the moving pulley through the conductive spring tube, so that the moving pulley can work again. When printing, the upper surface of the inkjet slides back and forth along the inner wall of the print head through the moving pulley, thereby realizing comprehensive printing of the lower material. However, each time the inkjet moves to the unidirectional end position, it needs to change direction immediately. However, the mass of the inkjet itself is usually large, and a large reverse force needs to be provided to the inkjet at this time. The moving pulley itself relies on friction to control the movement of the inkjet, so the moving pulley and the inner wall of the print head may slip, causing wear. Long-term work may cause the inkjet to move with difficulty and be unable to stop in time. The device buffers the inkjet through a folding tube and cuts off the power to the moving pulley at the same time, thereby realizing a smooth change of direction of the inkjet, thereby avoiding the problem of the inkjet being squeezed due to excessive reverse force on the inkjet.

[0011] Preferably, the control power supply box includes a conductive plate, both ends of the outer surface of the conductive plate are fixedly connected with insulating plates, the middle of the inner wall of the conductive plate is evenly provided with conductive spring cylinders, fixed batteries are symmetrically provided on both sides of the inner wall of the control power supply box, one end of the insulating plate away from the conductive plate is fixedly connected to the outer surface of the force-bearing block, the outer surface of the force-bearing block is slidably connected to the inner wall of the print head, the outer surface of the conductive plate is slidably connected to the inner wall of the control power supply box through a groove, the top of the fixed battery is slidably connected to the outer surface of the conductive spring cylinder, the upper part of the inner wall of the control power supply box is fixedly connected to the rotating machine of the movable pulley through a connecting wire, the upper surface of the inkjet is slidably connected to the axis of the upper part of the inner wall of the print head through the movable pulley, and the outer surface of the fixed hollow tube is fixedly connected to the inner wall of the print head. Because in the process of changing the direction of the inkjet, the folding tube exerts a thrust on the inkjet through its own elastic force. This avoids the problem of the movable pulley relying on reverse friction to change direction and causing wear on the outer surface of the wheel body. In addition, the control power box no longer supplies power during this process and the movable pulley does not work, so electric energy can be saved during the resetting process, greatly reducing the power consumption of the device during operation.

[0012] Select the material to be printed and place it on the left side of the conveyor belt and transport the material to the middle of the conveyor belt, then stop transporting, and then start the internal device of the bottom support table to insert the plug-in card block into the cutting groove of the conveyor belt. According to the different carrier materials, tighten the plug-in card blocks on both sides to clamp the material carrier, and then start the printing head to print on the upper surface of the material. After printing, release the clamping effect of the plug-in card block, separate the plug-in card block from the conveyor belt, and finally transport the printed material to the right end of the conveyor belt.

[0013] The beneficial effects of the present invention are as follows: 1. The device can transport the materials to be processed to the printing head in the middle for printing through a conveyor belt. If it is a hard material such as a printing plate, the plate can be reinforced by the plug-in blocks on the front and back sides to prevent the outer surface of the plate from generating relative friction with the printing head during the printing process, causing the plate to slide randomly, thereby avoiding the problem of obstruction of printing work or the problem of the printed product being completely unqualified due to errors.

[0014] 2. If printing is done on paper materials, the paper cannot be fixed by the mutual clamping effect of the front and rear plug-in blocks. At this time, the extended sliders extending from both sides can be used to press the upper surface of the paper, so that the paper cannot slide relative to each other during the printing process, thereby fixing the paper. The position where the paper is pressed is the corner, and even if indentation occurs, it can be eliminated by cutting the border, thereby ensuring the aesthetics of the finished paper.

[0015] 3. The device flexibly controls the movement of the air guide plate and the plug-in card block through the relevant structure inside the bottom support platform, so that the object moved to the middle of the transport conveyor belt can be fixed in the middle of the transport conveyor belt. Compared with the traditional card rack fixation, the device does not need to use a card rack to perform separate fixation work for each plate or paper, thereby avoiding the unnecessary process of clamping and unloading, making it convenient to use and saving the purchase cost of the card rack. At the same time, in the process of long-line transportation, the device can directly transport the printed products to the next work location, thereby omitting the handling work and improving production efficiency.

[0016] 4. When printing, the upper surface of the inkjet slides back and forth along the inner wall of the print head through the moving pulley, thereby realizing comprehensive printing of the lower material. However, each time the inkjet moves to the unidirectional end position, it needs to change direction immediately. However, the mass of the inkjet itself is usually large, and a large reverse force needs to be provided to the inkjet at this time. The moving pulley itself relies on friction to control the movement of the inkjet, so the moving pulley and the inner wall of the print head may slip, causing wear. Long-term work may cause the inkjet to move with difficulty and cannot be stopped in time. The device buffers the inkjet through a folding tube and cuts off the power to the moving pulley at the same time, thereby realizing a smooth change of direction of the inkjet, thereby avoiding the problem of the inkjet being squeezed due to excessive reverse force on the inkjet.

[0017] 5. During the change of direction of the inkjet, the folding tube applies thrust to the inkjet through its own elastic force. This avoids the problem of wear on the outer surface of the moving pulley due to the reverse friction force. In addition, the control power box will no longer supply power during this process, and the moving pulley will not work, so it can save energy during the reset process, greatly reducing the power consumption of the device during operation.

Example

[0021] See also Figure 1-Figure 5 The present invention provides a technical solution: a substrate printing track device of a substrate printer, comprising a transport conveyor belt 1, a side roller shaft 11 is arranged outside the transport conveyor belt 1, the number of the side roller shafts 11 is two, and the outer surface of the side roller shaft 11 is rotatably connected to the inner wall of the transport conveyor belt 1, the front and rear sides of the lower part of the outer surface of the side roller shaft 11 are rotatably connected to the main motor 21 through a friction sleeve, and the lower part of the outer surface of the main motor 21 is fixedly connected to the bottom support platform 2; a printing head 3, the lower part of the outer surface of the printing head 3 is slidably connected to the upper surface of the transport conveyor belt 1, the front and rear sides of the outer surface of the printing head 3 are symmetrically arranged with emission lamp heads 31, the upper surface of the printing head 3 is evenly arranged with hollow connecting rods 32, and the upper part of the inner wall of the hollow connecting rod 32 is fixedly connected to a pressurized fixing plate 33 through an air pipe; The bottom support platform 2 includes a side branch fixing plate 23, a light-transmitting lamp tube 24 is fixedly connected to the upper part of the inner wall of the side branch fixing plate 23, an inner guide tube 25 is fixedly connected to one end of the inner wall of the light-transmitting lamp tube 24 close to the bottom support platform 2, and guide rails 22 are symmetrically arranged on the front and rear sides of the axis of the outer surface of the bottom support platform 2, a bent connecting rod 4 is slidably connected to the inner wall of the guide rail 22, an air guide plate 5 is fixedly connected to the top end of the bent connecting rod 4, and a plug-in card block 51 is symmetrically arranged on the upper surface of the air guide plate 5; A fixed gear sleeve 41 is fixedly connected to the bottom end of the outer surface of the bent connecting rod 4, and a filling slider 42 is clamped on the upper and lower sides of the outer surface of the fixed gear sleeve 41 through clamping teeth. An auxiliary pulley 43 is rotatably connected to the axis of the inner wall of the filling slider 42. A threaded groove is provided on the inner wall of the fixed gear sleeve 41, and a threaded rotating rod 44 is threadedly connected to the side of the inner wall of the fixed gear sleeve 41 close to the bottom support platform 2 through the threaded groove. A torque motor 45 is fixedly connected to one end of the threaded rotating rod 44 away from the inner wall of the fixed gear sleeve 41, and a transmission arm 46 is rotatably connected to one side of the outer surface of the torque motor 45, and a control telescopic rod 47 is fixedly connected to the bottom end of the transmission arm 46.

[0022] The inner wall of the conveyor belt 1 is evenly provided with transverse through grooves, there are four bent connecting rods 4, the top ends of the bent connecting rods 4 extend to the inside of the conveyor belt 1, and the outer surface of the plug-in block 51 is slidably connected to the inner wall of the conveyor belt 1 through the transverse through grooves.

[0023] There are two emitting lamp heads 31, and a fixed rotating sleeve is sleeved on the outer surface of the emitting lamp head 31, and the upper part of the outer surface of the fixed rotating sleeve is rotatably connected to the axis of the outer surface of the printing end 3 through a rotating shaft. The side branch fixing plate 23 and the emitting lamp head 31 are both at the same mid-plane, and one end of the inner guide tube 25 close to the bottom support platform 2 is fixedly connected to the terminal ends of the torque motor 45 on both sides through an elastic wire.

[0024] The outer surface of the torque motor 45 housing is slidably connected to the inner wall of the bottom support platform 2, the outer surface of the threaded rotating rod 44 is slidably connected to the inner wall of the bottom support platform 2 through a vertical slide groove, and the outer surface of the filling slider 42 is slidably connected to the inner wall of the guide slide rail 22 through an auxiliary pulley 43.

[0025] When the device is used for printing, after the plate or paper to be printed is placed on the left side of the transport conveyor belt 1, the output shaft of the main motor 21 rotates, and the side rollers 11 on both sides are rotated clockwise through the friction sleeve 1, thereby causing the transport conveyor belt 1 to rotate clockwise, and the material located above is transported from left to right until the material is transported to the middle of the friction sleeve 1, and then the transportation is stopped and printing begins.

[0026] Before printing, the device needs to be powered on and started. At this time, the fixed rotating sleeves on the front and rear sides of the printing end 3 are rotated to a horizontal state. At this time, the emitting lamp head 31 is facing the light-transmitting lamp tube 24 below. After the side branch fixing plate 23 receives the light induction, the torque motors 45 on both sides are started through the inner guide tube 25, so that the device starts to fix the material, controls the extension of the two ends of the telescopic rod 47, and pushes the bottom end of the transmission arm 46 to both sides. At this time, the transmission arm 46 gradually changes from a bent state to a vertical state, and then pushes the torque motor 45 upward. At this time, the torque motor 45 pulls the bent connecting rod 4 to rise horizontally through the threaded rotating rod 44, so that the plug-in block 51 on the upper surface of the air guide plate 5 is directly inserted into the cross-sectional through groove of the transport conveyor belt 1.

[0027] If the middle material is a plate, and the four plug-in blocks 51 inserted into the transport conveyor belt 1 are not sufficient to clamp the outer surface of the plate, the output shaft of the torque motor 45 controls the threaded rotating rod 44 to rotate clockwise. When the threaded rotating rod 44 rotates clockwise, it will be inserted into the interior of the fixed gear sleeve 41 along the thread groove on the inner wall of the fixed gear sleeve 41. However, because the fixed gear sleeve 41 cannot be twisted under the blocking effect of the filling slider 42, and the torque motor 45 cannot move to one side of the fixed gear sleeve 41, the fixed gear sleeve 41 is pulled toward the torque motor 45. 5, so the bent connecting rods 4 on the front and rear sides begin to approach each other, and the plug-in card block 51 slides close to each other along the cross-sectional through groove of the inner wall of the transport conveyor belt 1, thereby clamping the middle plate. At this time, the upper surface of the plate is scanned and sprayed back and forth through the printing end 3, and the plate does not move relatively. After the processing is completed, the clamping effect of the plug-in card block 51 is released, and the air guide plate 5 is lowered. At this time, the plug-in card block 51 is separated from the inner wall of the transport conveyor belt 1, and the transport conveyor belt 1 is started again for transportation to obtain a finished product.

[0033] The printing end 3 includes an inkjet ejector 34, and a movable pulley 35 is fixedly connected to the upper surface of the inkjet ejector 34. A control power box 6 is symmetrically arranged on the left and right sides of the inner wall of the printing end 3. Force blocks 39 are symmetrically arranged on the front and rear ends of the control power box 6. A solid push rod 38 is fixedly connected to the top of the force block 39 away from the control power box 6, and a fixed hollow tube 36 is slidably connected to the side of the solid push rod 38 away from the force block 39, and a folding tube 37 is fixedly connected to the end of the fixed hollow tube 36 away from the solid push rod 38.

[0034] The control power box 6 includes a conductive plate 61, both ends of the outer surface of the conductive plate 61 are fixedly connected with insulating plates 62, the middle of the inner wall of the conductive plate 61 is evenly provided with conductive spring tubes 63, and fixed batteries 64 are symmetrically provided on both sides of the inner wall of the control power box 6.

[0035] One end of the insulating plate 62 away from the conductive plate 61 is fixedly connected to the outer surface of the force-bearing block 39, the outer surface of the force-bearing block 39 is slidably connected to the inner wall of the print end 3, the outer surface of the conductive plate 61 is slidably connected to the inner wall of the control power box 6 through a groove, the top of the fixed battery 64 is slidably connected to the outer surface of the conductive spring tube 63, the upper part of the inner wall of the control power box 6 is fixedly connected to the rotating machine of the movable pulley 35 through a connecting wire, the upper surface of the inkjet 34 is slidably connected to the axis center of the upper part of the inner wall of the print end 3 through the movable pulley 35, and the outer surface of the fixed hollow tube 36 is fixedly connected to the inner wall of the print end 3.

[0036] If printing is performed on paper materials, the paper cannot be fixed by the mutual clamping effect of the front and rear plug-in card blocks 51. At this time, it is necessary to start the air guide plate 5 after the plug-in card block 51 is inserted into the cross-sectional through-slot of the transport conveyor belt 1. The air guide plate 5 inflates the interior of the plug-in card block 51. Since the elastic coefficient of the connecting spring is smaller than the elastic coefficient of the spring belt, when the pressure inside the plug-in card block 51 increases, the connecting spring is first stretched. At this time, the inner slider 52 rises along the inner wall of the plug-in card block 51, allowing the top fixing frame 53 to pass through the cross-sectional through-slot of the transport conveyor belt 1. Subsequently, the extended sliders 54 on both sides begin to slide out from the inner wall of the top fixing frame 53 under the action of pressure. The limited length of the top fixing frame 53 is stretched, and then the bent connecting rod 4 is slid downward along the inner wall of the guide rail 22. At this time, the lower surfaces of the extended sliders 54 extending on both sides just clamp the upper surface of the paper with the upper surface of the transport conveyor belt 1, thereby achieving the effect of fixing the paper.

[0037] When printing, the upper surface of the inkjet 34 slides back and forth along the inner wall of the print head 3 through the movable pulley 35, thereby realizing comprehensive printing of the lower material. However, each time the inkjet 34 moves to the unidirectional end position, it needs to change direction immediately. However, the mass of the inkjet 34 itself is usually large, and a large reverse force needs to be provided to the inkjet 34 at this time. The movable pulley 35 itself relies on friction to control the movement of the inkjet 34, so the movable pulley 35 and the inner wall of the print head 3 may slip, thereby causing wear. Long-term operation may cause the inkjet 34 to have difficulty in moving and cannot be stopped in time.

[0038] When the inkjet 34 of the device moves, it will squeeze each other through the suction cup and the end of the folded tube 37. At this time, the folded tube 37 on the squeezed side will fill the gas into the interior of the fixed hollow tube 36, and the solid push rod 38 on the other side of the fixed hollow tube 36 begins to slide in the opposite direction along the inner wall of the fixed hollow tube 36 under the action of pressure, thereby pushing the force block 39 to slide along the inner wall of the force block 39. At this time, the insulating plate 62 pulls the conductive plate 61 to slide out of the control power box 6, and the fixed batteries 64 on both sides of the control power box 6 cannot be powered after being disconnected, so the moving pulley 35 is immediately powered off at this time, and the inkjet 34 begins to decelerate under the resistance of the folded tube 37. When the inkjet 34 stops moving, the compressed folded tube 37 begins to push back to the center position of the inner wall of the printing end 3, and the conductive plate 61 is reinserted into the control power box 6, and the fixed batteries 64 on both sides power the moving pulley 35 through the conductive spring tube 63, thereby making the moving pulley 35 work again.
