Description

Technical Field

[0001] This utility model relates to the field of sheet inkjet printer technology, specifically a sheet inkjet printer with belt paper feeding stability detection function. Background Technology

[0002] A coding machine is an industrial device used to quickly print variable information (such as text, numbers, barcodes, QR codes, dates, batch numbers, etc.) on the surface of products or packaging. It uses non-contact printing technology to accurately attach ink or laser markings to the surface of objects and is widely used in production lines to meet product identification, traceability and compliance requirements.

[0003] For example, the inkjet printer with detection function disclosed in the authorization announcement number CN218749940U includes a frame and a transverse slide, a longitudinal slide and an inkjet head disposed in the frame. The transverse slide is slidably connected to the longitudinal slide. The inkjet head includes a fixed base, a lifting base, a vertical drive device, a stepper motor, a drive wheel, a driven wheel, a synchronous belt and an inkjet printhead. The fixed base is slidably disposed on the transverse slide, and the lifting base is slidably connected to the fixed base.

[0004] Although the operator installs the movable block between a set of semicircular blocks, and uses the handle, the set of semicircular blocks, and the threaded support of the movable block to fix the movable block between the set of semicircular blocks, when the item after inkjet printing moves to the position corresponding to the rubber eraser, the operator controls the output end of the small motor to rotate back and forth clockwise and counterclockwise, so that the rubber eraser rubs back and forth with the inkjet position on the item. If the inkjet is not rubbed off, it is qualified; if the inkjet is rubbed off, it is unqualified. This realizes the quality detection of the inkjet printer's inkjet printing on the item. Under the operator's operation, the telescopic ends of the two sets of telescopic cylinders retract, so that they no longer clamp the item. The operator moves the inspected item away from the conveyor belt, and the two sets of telescopic cylinders move back to their original positions to continue to cooperate with the operator to clamp the item.

[0005] However, this does not solve the problem that existing sheet-fed inkjet printers are generally not convenient for detecting the stability of paper feeding, not convenient for picking out and collecting defective paper, not convenient for spraying paper of different widths and positions, and not convenient for adjusting the spacing to pick up and collect defective paper, thus affecting the efficiency of sheet-fed inkjet printers. Utility Model Content

[0006] The purpose of this utility model is to provide a sheet-fed inkjet printer with a belt-fed paper stability detection function, so as to solve the problems mentioned in the background art, such as the inconvenience of sheet-fed inkjet printers in detecting the stability of paper during feeding, the inconvenience of picking out and collecting unqualified paper, the inconvenience of spraying paper of different widths and positions, and the inconvenience of adjusting the spacing to pick up and collect unqualified paper, which affect the efficiency of sheet-fed inkjet printers.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a sheet-fed inkjet printer with belt-fed paper stability detection function, comprising a frame and a first conveyor. The first conveyor is disposed outside the frame, and a robotic arm is disposed outside the first conveyor. A vacuum adsorption conveyor is mounted on the top of the frame, and a support frame is mounted on the top of the vacuum adsorption conveyor. A first support frame is mounted on the side of the top of the vacuum adsorption conveyor away from the support frame, and a second support frame is mounted on the side of the top of the vacuum adsorption conveyor away from the first support frame. A movable plate is disposed outside the vacuum adsorption conveyor, and a movable bracket is mounted on the top of the robotic arm. A servo motor is mounted on the side wall of the first support frame. A first threaded rod is installed at the output end of the servo motor. The first threaded rod extends through the first support frame to its outside. A first threaded block is fitted on the surface of the first threaded rod. The first threaded rod and the first threaded block are threadedly connected. A first slide rail is installed at the top of the first support frame. A first slider is installed at the bottom of the first threaded block. The first slide rail and the first slider are slidably connected. A support plate is installed at the top of the first threaded block. A second slider is installed on the side of the support plate away from the first threaded block. A second slide rail is installed at the top of the second support frame. The second slider and the second slide rail are slidably connected. A longitudinal moving component is installed on the side wall of the support plate. A vision inspection instrument is installed at the bottom of the longitudinal moving component.

[0008] Preferably, a stepper motor is installed on the side wall of the support frame, and a second threaded rod is installed at the output end of the stepper motor. The second threaded rod extends through the support frame to its outside, and a second threaded block is fitted on the surface of the second threaded rod. The second threaded block is threadedly connected to the second threaded rod.

[0009] Preferably, an L-shaped plate is installed on the side wall of the second threaded block, and a coding machine nozzle is installed at the bottom end of the L-shaped plate. Power motors are installed on both sides of the frame, and a third threaded rod is installed at the output end of each power motor.

[0010] Preferably, all the third threaded rods extend through the frame to the outside of it, and all the surfaces of the third threaded rods are fitted with third threaded blocks, and all the third threaded blocks are connected to the moving plate.

[0011] Preferably, a variable frequency motor is installed on the side wall of the movable support, and a bidirectional threaded rod is installed at the output end of the variable frequency motor.

[0012] Preferably, the bidirectional threaded rod extends into the interior of the movable bracket and is movably connected thereto, and a fourth threaded block is symmetrically fitted onto the surface of the bidirectional threaded rod.

[0013] Preferably, the fourth threaded block is threadedly connected to the bidirectional threaded rod, and a connecting plate is installed at the bottom end of each fourth threaded block.

[0014] Preferably, connecting plates are installed on both sides of the connecting plate, and vacuum suction cups are symmetrically fitted on both sides of the connecting plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the sheet inkjet printer not only realizes the convenient detection of the stability of paper feeding, which makes it easy to pick out and collect unqualified paper, and makes it easy to spray paper of different widths and positions, but also makes it easy to adjust the spacing to pick up and collect unqualified paper, thus improving the efficiency of sheet inkjet printing.

[0016] (1) When using a sheet inkjet printer with belt feeding stability detection function, the paper is placed on the surface of the vacuum adsorption conveyor. The servo motor drives the first threaded rod to rotate. The first threaded rod drives the first threaded block to move. The first threaded block drives the support plate, longitudinal moving component and vision inspection instrument to move to the detection area to detect the paper. If the paper is detected to be stable on the surface of the vacuum adsorption conveyor, it is marked as qualified and continues to be conveyed to the spraying area for inkjet printing. If the paper is detected to be unstable or wrinkled, it is marked as unqualified. The robot uses a vacuum suction cup to pick up the unqualified paper and place it on the surface of the first conveyor for conveying and collection. This realizes that the sheet inkjet printer can conveniently detect the stability of the paper during conveying, which makes it convenient to pick out and collect the unqualified paper and improves the inkjet printing efficiency of the sheet inkjet printer.

[0017] (2) The stepper motor drives the second threaded rod to rotate, the second threaded rod drives the second threaded block to move, the second threaded block drives the L-shaped plate and the inkjet printer nozzle to move, so that the inkjet printer nozzle moves to the top of the paper to print. When it is necessary to adjust the width of the paper being transported, the power motor drives the third threaded rod to rotate, the third threaded rod drives the third threaded block to move, the third threaded block drives the moving plate to move, so that the moving plate can limit the transport of paper of different widths, realizing the convenient movement of the sheet inkjet printer for printing, facilitating the printing of paper of different widths and positions, and improving the printing range of the sheet inkjet printer.

[0018] The variable frequency motor drives the bidirectional threaded rod to rotate, which in turn drives two sets of fourth threaded blocks to move in opposite directions or in opposite directions to adjust the distance between the connecting plate, the connecting plate, and the vacuum suction cup. The vacuum suction cup picks up the paper, enabling the sheet inkjet printer to conveniently adjust the distance and pick up and collect unqualified paper. This facilitates the picking up of paper of different widths and improves the convenience of the sheet inkjet printer in picking up paper. Attached Figure Description

[0030] Example 1

[0031] Please see Figure 1-7This utility model provides an embodiment of a sheet inkjet printer with belt-fed paper stability detection function, comprising a frame 1 and a first conveyor 2. The first conveyor 2 is disposed outside the frame 1, and a robot arm 3 is disposed outside the first conveyor 2. A vacuum adsorption conveyor 4 is mounted on the top of the frame 1, and a support frame 5 is mounted on the top of the vacuum adsorption conveyor 4. A first support frame 6 is mounted on the side of the top of the vacuum adsorption conveyor 4 away from the support frame 5, and a second support frame 7 is mounted on the side of the top of the vacuum adsorption conveyor 4 away from the first support frame 6. A movable plate 8 is disposed outside the vacuum adsorption conveyor 4, and a movable bracket 27 is mounted on the top of the robot arm 3. A servo motor 9 is mounted on the side wall of the first support frame 6, and a first screw is mounted on the output end of the servo motor 9. A threaded rod 10 extends through the first support frame 6 to its outside. A first threaded block 11 is fitted on the surface of the first threaded rod 10. The first threaded rod 10 and the first threaded block 11 are threadedly connected. A first slide rail 13 is installed at the top of the first support frame 6. A first slider 14 is installed at the bottom of the first threaded block 11. The first slide rail 13 and the first slider 14 are slidably connected. A support plate 12 is installed at the top of the first threaded block 11. A second slider 16 is installed on the side of the support plate 12 away from the first threaded block 11. A second slide rail 15 is installed at the top of the second support frame 7. The second slider 16 and the second slide rail 15 are slidably connected. A longitudinal moving assembly 17 is installed on the side wall of the support plate 12. A visual inspection instrument 18 is installed at the bottom of the longitudinal moving assembly 17.

[0032] When using a sheet-fed inkjet printer with belt-fed paper stability detection, the vacuum adsorption conveyor 4 adopts the same model as the Elida S880. When paper needs to be inspected and marked, the paper is placed on the surface of the vacuum adsorption conveyor 4, and the vacuum adsorption conveyor 4 is turned on to convey the paper sequentially. When the paper reaches the detection area, the servo motor 9 is turned on. Supported by the first support frame 6, the servo motor 9 drives the first threaded rod 10 to rotate. With the threaded connection between the first threaded rod 10 and the first threaded block 11, the first threaded rod 10 moves the first threaded block 11. With the sliding connection between the first slider 14 and the first slide rail 13, and the sliding connection between the second slide rail 15 and the second slider 16, the first threaded block 11 moves the support plate 12, the longitudinal movement component 17, and the vision inspection instrument 18 to the detection area. The detection area inspects the paper. If the paper is stably conveyed on the surface of the vacuum suction conveyor 4, it is marked as qualified and continues to be conveyed to the spraying area for coding. If the paper is unstable or wrinkled, it is marked as unqualified. The robot arm 3 is then activated. The robot arm 3 uses the vacuum suction cup 33 to pick up the unqualified paper and place it on the surface of the first conveyor 2 for conveying and collection. The vision inspection instrument 18 feeds the data back to the external Internet computer via wires. The external Internet computer performs logical analysis and processing and controls the conveying of electrical equipment such as the robot arm 3, vacuum suction cup 33, and first conveyor 2. This enables the sheet inkjet printer to conveniently detect the stability of paper conveying, facilitates the picking out and collection of unqualified paper, and improves the coding efficiency of the sheet inkjet printer.

[0033] A stepper motor 19 is installed on the side wall of the support frame 5. A second threaded rod 21 is installed at the output end of the stepper motor 19. The second threaded rod 21 extends through the support frame 5 to its outside. A second threaded block 20 is fitted on the surface of the second threaded rod 21. The second threaded block 20 is threadedly connected to the second threaded rod 21.

[0034] An L-shaped plate 22 is installed on the side wall of the second threaded block 20. A coding machine nozzle 23 is installed at the bottom of the L-shaped plate 22. A power motor 24 is installed on both sides of the frame 1. A third threaded rod 25 is installed at the output end of the power motor 24.

[0035] The third threaded rod 25 extends through the frame 1 to its outside, and the surface of the third threaded rod 25 is fitted with a third threaded block 26, and the third threaded block 26 is connected to the moving plate 8.

[0036] When it is necessary to continue feeding and coding qualified paper, stepper motor 19 is turned on. Under the support of support frame 5, stepper motor 19 drives second threaded rod 21 to rotate. With the threaded connection between second threaded rod 21 and second threaded block 20, second threaded rod 21 drives second threaded block 20 to move. Second threaded block 20 drives L-shaped plate 22 and inkjet printer nozzle 23 to move, so that inkjet printer nozzle 23 moves above the paper for coding. When it is necessary to adjust the width of the paper being fed, two sets of power motors 24 are turned on. With the support of frame 1, power motor 24 drives third threaded rod 25 to rotate. With the threaded connection between third threaded rod 25 and third threaded block 26, third threaded rod 25 drives third threaded block 26 to move. Third threaded block 26 drives moving plate 8 to move, so that moving plate 8 can limit the feeding of paper of different widths. This realizes convenient movement of the sheet inkjet printer for coding, which facilitates the coating of paper of different widths and positions and improves the coating range of sheet inkjet printer.

[0037] A variable frequency motor 28 is installed on the side wall of the movable bracket 27. A bidirectional threaded rod 29 is installed at the output end of the variable frequency motor 28. The bidirectional threaded rod 29 extends into the interior of the movable bracket 27 and is movably connected thereto. A fourth threaded block 30 is symmetrically fitted on the surface of the bidirectional threaded rod 29.

[0038] The fourth threaded block 30 is threadedly connected to the bidirectional threaded rod 29. A connecting plate 31 is installed at the bottom of the fourth threaded block 30. A connecting plate 32 is installed on both sides of the connecting plate 31. Vacuum suction cups 33 are symmetrically fitted on both sides of the connecting plate 32.

[0039] When it is necessary to pick up and collect defective paper, the robotic arm 3 is activated. The robotic arm 3 moves the movable support 27 above the paper. The variable frequency motor 28 is activated. Supported by the movable support 27, the variable frequency motor 28 drives the bidirectional threaded rod 29 to rotate. With the threaded connection between the bidirectional threaded rod 29 and the fourth threaded block 30, the bidirectional threaded rod 29 drives the two sets of fourth threaded blocks 30 to move in opposite directions or in opposite directions to adjust the distance between the connecting plate 31, the connecting plate 32, and the vacuum suction cup 33. The paper is then picked up by the vacuum suction cup 33. This allows the sheet inkjet printer to conveniently adjust the distance to pick up and collect defective paper, making it easier to pick up paper of different widths and improving the convenience of the sheet inkjet printer in picking up paper.

[0040] Work steps

[0041] When using a sheet-fed inkjet printer with belt-fed paper stability detection, the vacuum suction conveyor 4 is turned on to transport the paper sequentially. When the paper reaches the detection area, the servo motor 9 drives the first threaded rod 10 to rotate. The first threaded rod 10 drives the first threaded block 11 to move. The first threaded block 11 drives the support plate 12, the longitudinal movement component 17, and the vision inspection instrument 18 to move to the detection area to detect the paper. If the paper is transported stably on the surface of the vacuum suction conveyor 4, it is marked as qualified and continues to be transported to the spraying area for inkjet printing. If the paper is transported unstablely or is wrinkled, it is marked as unqualified. The robot arm 3 uses the vacuum suction cup 33 to pick up the unqualified paper and place it on the surface of the first conveyor 2 for transport and collection. The stepper motor 19 drives the second threaded rod 21 to rotate. The second threaded rod 21 drives the second threaded block 20 to move. The second threaded block 20 moves the L-shaped plate 22 and the inkjet printer nozzle 23, causing the inkjet printer nozzle 23 to move above the paper for printing. When the width of the paper to be conveyed needs to be adjusted, the power motor 24 drives the third threaded rod 25 to rotate. The third threaded rod 25 moves the third threaded block 26, which in turn moves the moving plate 8, allowing the moving plate 8 to limit the conveying of paper of different widths. When it is necessary to pick up and collect unqualified paper, the robot arm 3 moves the moving bracket 27 above the paper, and the frequency conversion motor 28 drives the bidirectional threaded rod 29 to rotate. The bidirectional threaded rod 29 drives the two sets of fourth threaded blocks 30 to move in opposite directions or in opposite directions to adjust the distance between the connecting plate 31, the connecting plate 32, and the vacuum suction cup 33. The vacuum suction cup 33 picks up the paper to complete the operation of the sheet inkjet printer.
