Description

Technical Field

[0001] This utility model relates to the technical field of printhead guide rail calibration equipment, specifically a calibration structure for the straightness of a printhead guide rail for an inkjet printer. Background Technology

[0002] During the operation of an inkjet printer, the printhead needs to move stably along the guide rail to complete continuous printing. The straightness of the guide rail is the core indicator to ensure the clarity and positional accuracy of the printing. At present, the industry mainly uses manual methods such as dial indicators and straightedges to calibrate the straightness of the printhead guide rail. The calibration process requires multiple adjustments to the guide rail support position and repeated measurements, and the whole process depends on the operator's experience and judgment.

[0003] Existing calibration procedures are cumbersome, relying heavily on manual adjustments based on experience, resulting in low calibration efficiency, a lack of precise adjustment components, poor calibration accuracy, and an inability to meet the requirements of high-precision inkjet printing. Furthermore, the calibration process cannot detect changes in the straightness of the guide rail in real time, and cannot provide timely feedback on the calibration effect, leading to insufficient stability of the straightness of the calibrated guide rail. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a calibration structure for the straightness of the inkjet printer printhead guide rail, thereby solving the problems mentioned in the background. This invention features a novel structure, incorporating an adjusting block, adjusting bolt, roller, bracket, trigger switch, and buzzer. The adjustment bolt and adjusting block work together to achieve precise adjustment of the guide rail, eliminating the need for manual operation based on experience and improving calibration efficiency. The roller slides along the guide rail with the slider; if there is a deviation in the guide rail, it will cause the bracket to rotate, triggering the switch and activating the buzzer. This enables real-time detection and timely feedback of changes in guide rail straightness during calibration, ensuring the stability of the guide rail straightness after calibration.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a linearity calibration structure for a printer nozzle guide rail, comprising a positioning plate, multiple support frames fixedly connected to the upper side of the positioning plate, support seats fixedly connected to the upper side of the multiple support frames, a transverse adjusting bolt threaded onto one side of the support seat, a transverse adjusting block rotatably fitted at one end of the transverse adjusting bolt, a longitudinal adjusting bolt threaded onto the lower side of the support seat, a longitudinal adjusting block rotatably fitted at the upper end of the longitudinal adjusting bolt, two limiting mechanisms symmetrically arranged on the upper side of the positioning plate, a linear guide rail arranged on the upper side of the multiple support seats, a guide rail slider slidably fitted on the linear guide rail, a mounting box arranged on the upper side of the guide rail slider, a snap-fit ​​mechanism arranged inside the mounting box, a support plate fixedly connected to the upper side of the mounting box, two L-shaped brackets rotatably fitted on one side of the support plate, and rollers rotatably fitted at the lower ends of the L-shaped brackets that cooperate with the upper side of the linear guide rail.

[0006] Furthermore, the lateral adjusting block is slidably fitted on one side of the inner wall of the support base, and the longitudinal adjusting block is slidably fitted on the lower side of the inner wall of the support base.

[0007] Furthermore, trigger plates are fixedly connected to the upper ends of both L-shaped brackets, and two sets of trigger switches that cooperate with the trigger plates are fixedly connected to one side of the support plate.

[0008] Furthermore, a horizontal plate is fixedly connected to one side of the support plate, and two mounting rods are fixedly connected to the lower side of the horizontal plate. A second spring is fixedly connected to the lower end of the mounting rod, and the lower end of the second spring is fixedly connected to the upper side of the L-shaped bracket. A buzzer electrically connected to the trigger switch is installed on the upper side of the mounting box.

[0009] Furthermore, the limiting mechanism includes a fixed plate fixedly connected to the upper side of the positioning plate, a threaded rod threadedly engaged on one side of the fixed plate, a side pressure plate rotatably engaged at one end of the threaded rod, and two limiting plates fixedly connected to one side of the side pressure plate.

[0010] Furthermore, the two limiting plates are slidably fitted on one side of the fixed plate, and one side of the side pressure plate is fitted with the linear guide rail.

[0011] Furthermore, the snap-fit ​​mechanism includes a gear shaft rotatably fitted on the inner wall of the mounting box. The inner wall of the mounting box has two connecting plates that slide together. A rack that meshes with the gear shaft is fixedly connected to one side of each of the two connecting plates. A snap-fit ​​plate is fixedly connected to the opposite side of each of the two connecting plates. Limiting rods are fixedly connected to both sides of the inner wall of the mounting box. A first spring is sleeved on the limiting rod. A knob is fixedly connected to the upper end of the gear shaft extending to the upper side of the mounting box. Slots that engage with the snap-fit ​​plates are provided on both sides of the guide rail slider.

[0012] Furthermore, the buckle plate is slidably fitted on both sides of the mounting box, the connecting plate is slidably fitted on the limiting rod, and the two ends of the first spring abut against the mounting box and the connecting plate respectively.

[0013] The beneficial effects of this utility model are:

[0014] 1. This utility model, through the setting of an adjusting block, adjusting bolt, roller, bracket, trigger switch and buzzer, etc., achieves precise adjustment of the guide rail by the cooperation of the adjusting bolt and adjusting block, eliminating the need for manual operation based on experience and improving calibration efficiency. The roller slides on the guide rail with the slider. If there is a deviation in the guide rail, it will drive the bracket to rotate, causing the trigger plate to trigger the switch, and the buzzer will then sound an alarm. This realizes real-time detection and timely feedback of changes in the straightness of the guide rail during the calibration process, ensuring the stability of the straightness of the guide rail after calibration.

[0015] 2. By setting a limiting structure such as a fixed plate, a threaded rod, a side pressure plate, and a limiting plate, this utility model can stably limit the lateral position of the guide rail. Rotating the threaded rod can drive the side pressure plate to move and press against the guide rail, preventing the guide rail from shifting laterally during adjustment and use, further ensuring the stability of the guide rail position after calibration, and helping to improve the reliability of the overall structure.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] Please refer to Figures 1 to 5This utility model provides a technical solution: a linearity calibration structure for a printer nozzle guide rail, including a positioning plate 1, multiple support frames 2 fixedly connected to the upper side of the positioning plate 1, support seats 3 fixedly connected to the upper side of the multiple support frames 2, a transverse adjusting bolt 4 threadedly fitted on one side of the support seat 3, a transverse adjusting block 5 rotatably fitted at one end of the transverse adjusting bolt 4, a longitudinal adjusting bolt 6 threadedly fitted on the lower side of the support seat 3, a longitudinal adjusting block 7 rotatably fitted at the upper end of the longitudinal adjusting bolt 6, two limiting mechanisms 8 symmetrically arranged on the upper side of the positioning plate 1, a linear guide rail 9 arranged on the upper side of the multiple support seats 3, a guide rail slider 10 slidably fitted on the linear guide rail 9, a mounting box 11 arranged on the upper side of the guide rail slider 10, a snap-fit ​​mechanism 12 arranged inside the mounting box 11, a support plate 13 fixedly connected to the upper side of the mounting box 11, two L-shaped brackets 14 rotatably fitted on one side of the support plate 13, and a roller 15 rotatably fitted at the lower end of the L-shaped bracket 14 that cooperates with the upper side of the linear guide rail 9. The horizontal adjusting block 5 is slidably fitted on one side of the inner wall of the support base 3, and the vertical adjusting block 7 is slidably fitted on the lower side of the inner wall of the support base 3. A trigger plate 16 is fixedly connected to the upper end of each of the two L-shaped brackets 14. Two sets of trigger switches 17, which cooperate with the trigger plates 16, are fixedly connected to one side of the support plate 13. A horizontal plate 18 is fixedly connected to one side of the support plate 13. Two mounting rods 19 are fixedly connected to the lower side of the horizontal plate 18. A second spring 20 is fixedly connected to the lower end of the mounting rod 19. The lower end of the second spring 20 is fixedly connected to the upper side of the L-shaped bracket 14. A buzzer 21, electrically connected to the trigger switch 17, is installed on the upper side of the mounting box 11. The linear guide rail 9 is placed on multiple support bases 3. The horizontal adjustment bolt 4 can be rotated to drive the horizontal adjustment block 5 to slide on one side of the inner wall of the support base 3 to adjust the horizontal position of the linear guide rail 9. The vertical adjustment bolt 6 can be rotated to drive the vertical adjustment block 7 to slide on the lower side of the inner wall of the support base 3 to adjust the vertical position of the linear guide rail 9. When the guide rail slider 10 slides on the linear guide rail 9, it drives the mounting box 11 and related components to move. The roller 15 rolls in contact with the upper side of the linear guide rail 9. If there is a deviation in the linear guide rail 9, the L-shaped bracket 14 will rotate, and the trigger piece 16 will move accordingly, triggering the corresponding trigger switch 17. The buzzer 21 will sound an alarm after receiving the signal. The horizontal and vertical adjustment bolts, together with the corresponding adjustment blocks, can achieve precise adjustment of the linear guide rail 9. The roller 15, L-shaped bracket 14, trigger piece 16, trigger switch 17 and buzzer 21 form a detection and early warning structure, which can detect the straightness of the linear guide rail 9 in real time during the movement of the guide rail slider 10 and issue a deviation alarm in time.

[0024] In this embodiment, the limiting mechanism 8 includes a fixed plate 81 fixedly connected to the upper side of the positioning plate 1. A threaded rod 82 is threadedly engaged on one side of the fixed plate 81, and a side pressure plate 83 is rotatably engaged at one end of the threaded rod 82. Two limiting plates 84 are fixedly connected to one side of the side pressure plate 83. The two limiting plates 84 are slidably engaged on one side of the fixed plate 81, and one side of the side pressure plate 83 engages with the linear guide rail 9. Rotating the threaded rod 82 causes it to rotate threadedly on the fixed plate 81, driving the side pressure plate 83 to move. The side pressure plate 83 drives the limiting plates 84 to slide on one side of the fixed plate 81 until the side pressure plate 83 contacts and abuts against the side of the linear guide rail 9. The movement of the side pressure plate 83 is achieved through the threaded transmission of the threaded rod 82, which laterally limits and fixes the linear guide rail 9, preventing lateral displacement of the linear guide rail 9 during adjustment and use. The limiting plates 84 act as guides, ensuring the smooth movement of the side pressure plate 83.

[0025] In this embodiment, the snap-fit ​​mechanism 12 includes a gear shaft 121 rotatably fitted on the inner wall of the mounting box 11. Two connecting plates 122 are slidably fitted on the inner wall of the mounting box 11. A rack 123 meshing with the gear shaft 121 is fixedly connected to one side of each connecting plate 122, and a snap-fit ​​plate 124 is fixedly connected to the opposite side of each connecting plate 122. Limiting rods 125 are fixedly connected to both sides of the inner wall of the mounting box 11, and a first spring 126 is sleeved on each limiting rod 125. A knob 127 is fixedly connected to the upper end of the gear shaft 121 extending to the upper side of the mounting box 11. Slots 128 for engaging with the snap-fit ​​plates 124 are provided on both sides of the guide rail slider 10. The snap-fit ​​plates 124 are slidably fitted on both sides of the mounting box 11, and the connecting plates 122 are slidably fitted on the limiting rods 125. The two ends of the first spring 126 abut against the mounting box 11 and the connecting plates 122, respectively. Rotating the knob 127 drives the gear shaft 121 to rotate. The gear shaft 121 meshes with the rack 123, causing the two connecting plates 122 to slide on the limiting rod 125 and move closer to each other. The snap plate 124 moves and disengages from the slot 128 of the guide rail slider 10. The first spring 126 is compressed. Releasing the knob 127 resets the first spring 126, pushing the connecting plate 122 to reset. The snap plate 124 snaps into the slot 128. Through gear and rack transmission and spring reset, the snap plate 124 and the guide rail slider 10 slot 128 are quickly engaged and disengaged, facilitating the assembly and disassembly of the mounting box 11 and the guide rail slider 10. The limiting rod 125 ensures the stable sliding of the connecting plate 122.

[0026] When using the device, place the linear guide 9 on the support base 3, operate the limiting mechanism 8, and rotate the threaded rod 82 to make the side pressure plate 83 press against the side of the linear guide 9 to complete the limiting. If it is necessary to adjust the straightness of the linear guide 9, the horizontal adjusting bolt 4 and the vertical adjusting bolt 6 are used to drive the horizontal adjusting block 5 and the vertical adjusting block 7 to move, thereby adjusting the linear guide 9 horizontally and vertically. During installation, rotate the knob 127 of the locking mechanism 12 to open the buckle plate 124, put the mounting box 11 on the guide rail slider 10, and release the knob 127. Under the action of a spring 126, the device is inserted into the slot 128 to complete the installation. During use, the guide rail slider 10 slides on the linear guide rail 9, driving the mounting box 11 and support plate 13 and other components to move. The roller 15 rolls along the upper side of the linear guide rail 9. If there is a straightness deviation in the linear guide rail 9, the roller 15 drives the L-shaped bracket 14 to rotate, the trigger plate 16 triggers the trigger switch 17, and the buzzer 21 sounds an alarm. At the same time, the second spring 20 can reset the L-shaped bracket 14. Through the coordination of the above structures, the linear guide rail 9 can be limited, adjusted, detected, and related components can be easily disassembled and assembled.

It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.

[0028] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
