Description

Technical Field

[0001] This utility model relates to the field of inkjet printing machine technology, and in particular to a side-limiting mechanism for a sheet metal of a double-table inkjet printer. Background Technology

[0002] Dual-table inkjet printers are widely used in industrial production, primarily for printing patterns, text, or markings on the surfaces of materials such as sheet metal. With the development of industrial automation and intelligent manufacturing, higher demands are being placed on the precision, efficiency, and automation level of inkjet printers. During the printing process, the positioning and limiting of the sheet metal are key factors in ensuring printing quality. Therefore, the side-limiting mechanism of the sheet metal plays a crucial role in dual-table inkjet printers. Traditional limit devices often use fixed baffles or simple manual adjustment methods, which are difficult to achieve high-precision positioning. During the printing process, the positional accuracy of the printing plate directly affects the printing quality. Insufficient positioning accuracy will lead to offset or inaccurate printing patterns, affecting the appearance and quality of the product. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a side-limiting mechanism for the printing plate of a double-table inkjet printer.

[0004] This utility model adopts the following technical solution: a side limiting mechanism for a double-tabletop inkjet printer, including a support base, a support bar fixedly connected to the top of the support base, a threaded rod provided at the bottom of the support bar, two threaded rods, a moving block connected to the surface of the two threaded rods, two moving blocks, a connecting block fixedly connected to the end of the two moving blocks that are close to each other, two connecting blocks, a rotating shaft fixedly connected to the inner wall of the two connecting blocks, four rotating shafts, a sliding wheel connected to the surface of the four rotating shafts, four sliding wheels slidably connected to the surface of the support bar, the four sliding wheels being symmetrically distributed around the center of the support bar, a connecting column fixedly connected to the inner wall of the two connecting blocks, two connecting columns, a side locking block connected to the surface of the two connecting columns, two side locking blocks, the ends of the two side locking blocks that are far from each other contact the inner wall of the support bar, the two side locking blocks being symmetrically distributed around the center of the inner wall of the support bar.

[0005] Through the above technical solution, the threaded rod is connected to the servo motor, converting the motor's rotational motion into the linear motion of the moving block. This achieves precise adjustment of the printing component's position, making it a key component for automated control. Utilizing the transmission characteristics of the thread, high-precision position adjustment is achieved, meeting the precise positional requirements of different printing needs. The sliding wheel slides on the support bar surface, while the rotating shaft ensures stable rotation of the sliding wheel, allowing the moving block to move smoothly and steadily along the support bar, reducing friction and resistance during movement and improving stability and reliability. Working in conjunction with the support bar, it guides and positions the moving block, ensuring accurate movement along a predetermined trajectory and improving positional adjustment accuracy. The limit locking block, driven by the connecting column, contacts the inner wall of the support bar, locking and fixing the moving block to prevent displacement due to external forces during printing. This ensures the stability of the printing component's position, thereby guaranteeing printing quality. During printing, the limit locking block also provides safety protection, preventing printing errors or equipment damage caused by accidental movement of the moving block.

[0006] As a further improvement to the above solution, a servo motor is fixedly connected to the top of the support bar. There are two servo motors. The output ends of the two servo motors are connected to the tops of two threaded rods through the inside of the support bar. Limiting plates are fixedly connected to the bottoms of the two threaded rods. There are two limiting plates.

[0007] Through the above technical solution, the limiting plate is installed at the bottom of the threaded rod, which plays the role of limiting the movement stroke of the moving block, preventing the moving block from disengaging from the threaded rod due to excessive movement, ensuring the safe operation of the equipment, increasing the structural strength of the bottom of the threaded rod, and improving the stability and reliability of the entire transmission system.

[0008] As a further improvement to the above solution, a mounting frame is fixedly connected to one end of the two connecting blocks that are close to each other, a movable placement frame is slidably connected to the surface of the mounting frame, and a printing assembly is fixedly connected to the bottom end of the movable placement frame.

[0009] Through the above technical solution, the mounting frame is used to install the printing components, and the movable placement frame can slide on the surface of the mounting frame to realize the horizontal position adjustment of the printing components, so that the printing components can be flexibly adjusted according to different printing needs and board positions, thereby improving the applicability and flexibility of the printing machine.

[0010] As a further improvement to the above solution, the inner wall of the support base is fixedly connected with a connecting strip. There are two connecting strips, and each of the two connecting strips has a movable plate at its upper and lower ends. There are several movable plates, and each movable plate has a placement plate fixedly connected to its top. A rotating shaft is fixedly connected to one end of each movable plate that is close to the other.

[0011] The above technical solution provides support and guidance for the moving plate and wheels, fixedly connected to the inner wall of the support base. This allows the moving plate to move smoothly along the connecting strip, acting like a track to ensure accurate and stable movement. A placement plate is fixedly connected to the top for holding the printing plate. By moving along the connecting strip, the position of the placement plate can be adjusted to accommodate plates of different sizes, ensuring accurate placement within the printing area and improving the equipment's adaptability.

[0012] As a further improvement to the above solution, a plurality of rotating shafts are provided, and a plurality of movable wheels are connected to the surfaces of the plurality of rotating shafts. A plurality of movable wheels are provided, and the surfaces of the plurality of movable wheels are slidably connected to the surfaces of two connecting strips. A plurality of locking bolts are provided at the bottom ends of a plurality of movable plates, and the plurality of locking bolts are threadedly connected to the interior of the plurality of rotating shafts through the interior of the plurality of movable plates.

[0013] Through the above technical solution, the moving wheel slides on the surface of the connecting strip, and the rotating shaft ensures the stable rotation of the moving wheel, enabling the moving plate to move smoothly and steadily along the connecting strip. This reduces friction and resistance during movement, improving the stability and reliability of the movement. In conjunction with the connecting strip, it guides and positions the moving plate, ensuring accurate movement along a predetermined trajectory and improving the precision of position adjustment. Through threaded connections inside the moving plate and the rotating shaft, the moving plate is fixed to the connecting strip, preventing displacement due to external forces during printing and ensuring the stability of the plate's position, thereby guaranteeing printing quality. When adjusting the position of the moving plate, the locking bolts can be loosened for movement, and then tightened after adjustment to the appropriate position, achieving quick and convenient position adjustment and locking, improving the ease of operation of the equipment.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model, through the transmission connection of the threaded rod and the moving block, can precisely adjust the distance between the printing component and the board, ensuring high precision in the printing process. The design of the limit locking block can effectively prevent the moving block from shifting during the printing process, further improving the stability of positioning. The sliding connection design of the mounting bracket and the movable placement bracket allows the printing components to be adjusted in position as needed, increasing the flexibility and applicability of the printer. The position adjustment of the printing components is not limited to the horizontal direction, but can also be adjusted vertically by moving the moving block up and down to meet different printing needs. This invention achieves automatic movement of the moving block by using a servo motor, reducing manual operation and improving work efficiency. The precise control of the servo motor can quickly and accurately adjust the position of the printing components to adapt to different sizes of boards. Attached Figure Description

[0019] A servo motor 3 is fixedly connected to the top of the support bar 2. There are two servo motors 3. The output ends of the two servo motors 3 are connected to the top of the two threaded rods 4 through the inside of the support bar 2. The bottom of the two threaded rods 4 is fixedly connected to a limit plate 5. There are two limit plates 5.

[0020] Two connecting blocks 7 are fixedly connected to one end of each other with a mounting bracket 18. A movable placement bracket 19 is slidably connected to the surface of the mounting bracket 18. A printing assembly 20 is fixedly connected to the bottom of the movable placement bracket 19.

[0021] There are two connecting strips 16 fixedly connected to the inner wall of the support base 1.
