Description
Technical Field
[0001] This utility model relates to the field of printing technology, specifically a printing calibration and positioning device. Background Technology
[0002] Printing is a technology that copies text, images, and other information onto substrates such as paper, cloth, and metal. Its core is to achieve the mass and efficient dissemination of information through steps such as plate making, inking, and pressing. It transforms fleeting language or design into physical carriers that can be preserved for a long time, breaking the limitations of handwriting and allowing an original piece of content to generate thousands of copies. This has promoted the popularization of media such as books, newspapers, and posters, and has become an important tool for the transmission of knowledge, art, and commercial information.
[0003] In stencil printing, a screen printing plate with graphic patterns is usually fixed on a printing press or stand, maintaining a certain distance between the screen and the substrate. Ink is then poured onto one end of the screen, and a squeegee is used to scrape it evenly from one end to the other. The pressure of the squeegee causes the screen and substrate to adhere to each other at the moment of scraping, forcing the ink through the mesh of the graphic portion of the screen and accurately printing onto the substrate surface. When fixing the substrate, a baseline is marked on the printing table or a positioning block is installed according to the size of the substrate and the position requirements of the printed pattern, so that the substrate can be placed in accordance with the baseline for quick positioning and printing. However, in actual use, if the baseline or block is fixed, it can only be used for substrates of a specific size. If different sizes of materials are printed later, the baseline needs to be remeasured, marked, or the block needs to be disassembled and replaced, which is not only time-consuming and labor-intensive, but may also cause baseline deviation due to repeated adjustments. Therefore, we propose a printing calibration and positioning device. Utility Model Content
[0004] The purpose of this invention is to provide a printing calibration and positioning device to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a printing calibration and positioning device, comprising a base, a frame mounted on the surface of the base, a printing plate mounted on the inner wall of the frame, a positioning structure provided on the surface of the base, the positioning structure comprising a plurality of rectangular grooves, the plurality of rectangular grooves being respectively opened on multiple sides of the base, a threaded rod rotatably connected to the inner wall of the rectangular groove, a drive plate threadedly connected to the surface of the threaded rod, and a positioning plate fixedly connected to one end of the drive plate.
[0006] The effect achieved by the above components is as follows: by setting up a positioning structure, it is easy to adjust the position of the positioning plate according to the size of the substrate, thereby facilitating the positioning of the substrate. The positioning plate always maintains the positioning state of the substrate, ensuring that the substrate will not shift due to the pushing force of the squeegee or the bonding pressure of the printing plate.
[0007] Preferably, a rubber pad A is fixedly connected to the side of the positioning plate away from the drive plate.
[0008] The effect achieved by the above components is that the edge of the substrate contacts the rubber pads A on the outside of the multiple positioning plates. The flexible material of the rubber pads A can prevent the positioning plates from causing hard compression damage to the edge of the substrate. At the same time, the friction of the rubber enhances the adhesion stability between the substrate and the positioning plates, preventing the substrate from shifting during the subsequent printing process.
[0009] Preferably, a rubber pad B is placed on the surface of the rubber pad A, and both the surface of the rubber pad A and the rubber pad B have circular grooves. A cylinder is fixedly connected to the side of the rubber pad B near the rubber strip A, and the size of the cylinder is adapted to the size of the circular groove.
[0010] The effect achieved by the above components is as follows: if the substrate to be printed is thick, rubber pad B can be placed on the surface of rubber pad A, and the arc on the surface of rubber pad B can be inserted into the circular groove on the surface of rubber pad B for fixation, thereby further improving the positioning effect of the substrate to be printed.
[0011] Preferably, a guide rod slides through the surface of the drive plate, and one end of the guide rod is fixedly connected to the inner wall of the rectangular groove.
[0012] The effect achieved by the above components is that the guide rod that slides through the surface of the drive plate restricts the movement trajectory of the drive plate, prevents it from deviating as the threaded rod rotates, and ensures that the drive plate always moves smoothly along the axial direction of the guide rod.
[0013] Preferably, a handle is fixedly connected to one end of the threaded rod, and a plurality of anti-slip strips are fixedly connected to the arc surface of the handle.
[0014] The effect achieved by the above components is that when the operator holds the handle at the end of the threaded rod, the anti-slip strip on its arc surface can increase the friction of the hand and prevent slippage when rotating.
[0015] Preferably, the surface of the drive plate is uniformly and fixedly connected with several scale marks.
[0016] The effect achieved by the above components is that when adjusting the position of the positioning plate, the operator can observe the adjustment distance through the scale markings on the surface of the drive plate, and make the spacing between multiple positioning plates fit perfectly by reading the scale markings corresponding to the positioning plate, thus achieving visual and precise adjustment.
[0017] Preferably, the drive plate has a plurality of ball bearings rotatably connected to the side near the base.
[0018] The effect achieved by the above components is that the ball bearings at the bottom of the drive plate contact the surface of the base, converting the sliding friction between the drive plate and the base into rolling friction, greatly reducing the resistance during adjustment and making the movement of the positioning plate smoother.
[0019] Compared with the prior art, the beneficial effects of this utility model are: This utility model, through the setting of a positioning structure, allows the operator to rotate a threaded rod, which in turn drives a drive plate to move. The drive plate then moves positioning plates, ensuring that the spacing between multiple positioning plates is precisely matched. Once all positioning plates are adjusted to positions suitable for the size of the substrate, the substrate to be printed is placed in the printing area at the center of the base. At this point, the edge of the substrate contacts the multiple positioning plates, making it easy to adjust the position of the positioning plates according to the size of the substrate. This facilitates the positioning of the substrate, ensuring that the substrate does not shift due to the pushing force of the squeegee or the adhesion pressure of the printing plate.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figure 1-2This utility model provides a technical solution: a printing calibration and positioning device, including a base 1, a frame 2 mounted on the surface of the base 1, a printing plate 3 mounted on the inner wall of the frame 2, and a positioning structure 4 provided on the surface of the base 1. The positioning structure 4 includes several rectangular grooves 401, which are respectively opened on multiple sides of the base 1. A threaded rod 402 is rotatably connected to the inner wall of the rectangular groove 401, and a drive plate 403 is threadedly connected to the surface of the threaded rod 402. A positioning plate 404 is fixedly connected to one end of the drive plate 403. By setting the positioning structure 4, the position of the positioning plate 404 can be easily adjusted according to the size of the object to be printed, thereby facilitating the positioning and placement of the object to be printed. The positioning plate 404 always maintains the positioning state of the object to be printed, ensuring that the object to be printed will not shift due to the pushing force of the squeegee or the adhesion pressure of the printing plate 3.
[0024] Reference Figure 3-5As shown in this embodiment: a rubber pad A405 is fixedly connected to the side of the positioning plate 404 away from the drive plate 403. The edge of the substrate contacts the rubber pads A405 on the outer side of the multiple positioning plates 404. The flexible material of the rubber pads A405 can prevent the positioning plates 404 from causing hard compression damage to the edge of the substrate. At the same time, the friction of the rubber enhances the adhesion stability between the substrate and the positioning plates 404, preventing the substrate from shifting during the subsequent printing process. A rubber pad B408 is placed on the surface of rubber pad A405. Both rubber pads A405 and B408 have circular grooves 406 on their surfaces. A cylinder 407 is fixedly connected to the side of rubber pad B408 near the rubber strip A. The size of the cylinder 407 matches the size of the circular groove 406. If the substrate to be printed is thick, rubber pad B408 can be placed on the surface of rubber pad A405, and the arc of the surface of rubber pad B408 can be inserted into the circular groove 406 on the surface of rubber pad B408 for fixation, thereby further improving the positioning effect of the substrate to be printed. A guide rod 409 slides through the surface of the drive plate 403. One end of the guide rod 409 is fixedly connected to the inner wall of the rectangular groove 401. The guide rod 409 sliding through the surface of the drive plate 403 restricts the movement trajectory of the drive plate 403, preventing it from shifting with the rotation of the threaded rod 402, and ensuring that the drive plate 403 always moves smoothly along the axial direction of the guide rod 409. A handle 410 is fixedly connected to one end of the threaded rod 402. Several anti-slip strips 411 are fixedly connected to the arc-shaped surface of the handle 410. When the operator grips the handle 410 at the end of the threaded rod 402, the anti-slip strips 411 on the arc-shaped surface increase hand friction, preventing slippage during rotation. Several scale markings 412 are evenly fixedly connected to the surface of the drive plate 403. When adjusting the position of the positioning plate 404, the operator can observe the adjustment distance through the scale markings 412 on the surface of the drive plate 403. By reading the corresponding scale markings 412 on the positioning plate 404, the distance between the multiple positioning plates 404 can be precisely matched, achieving visual and precise adjustment. Several ball bearings 413 are rotatably connected to the side of the drive plate 403 near the base 1. The ball bearings 413 at the bottom of the drive plate 403 contact the surface of the base 1, converting the sliding friction between the drive plate 403 and the base 1 into rolling friction, significantly reducing resistance during adjustment and making the movement of the positioning plate 404 smoother.
[0025] Working Principle: Before printing, the device is first placed on a horizontal printing table, ensuring that the base 1 is stable and does not wobble. The frame 2 and the printing plate 3 fixed to the inner wall are in the preset printing position. The drive plate 403 and the positioning plate 404 are both in their initial positions, that is, the positioning plate 404 maintains a certain distance from the center printing area of the base 1, leaving space for the substrate. Then, the operator holds the handle 410 at the end of the threaded rod 402. The anti-slip strip 411 on its arc surface increases the friction of the hand and prevents slippage during rotation. By rotating the handle 410 clockwise or counterclockwise, the threaded rod 402 is driven to rotate synchronously at the rotation connection point on the inner wall of the rectangular groove 401. Since the drive plate 403 and the threaded rod 402 are threadedly connected, the threaded rod 402 rotates synchronously at the rotation connection point on the inner wall of the rectangular groove 401. The rotational motion of the threaded rod 402 is converted into the linear motion of the drive plate 403. Simultaneously, the guide rod 409, which slides through the surface of the drive plate 403, restricts its movement trajectory, preventing it from shifting as the threaded rod 402 rotates. This ensures that the drive plate 403 always moves smoothly along the axial direction of the guide rod 409. As the drive plate 403 moves, it simultaneously moves the positioning plate 404, fixed at one end, closer to or further away from the central printing area of the base 1. The operator can observe and adjust the distance through the scale markings 412 on the surface of the drive plate 403. By reading the corresponding scale markings 412 on the positioning plate 404, the spacing between multiple positioning plates 404 can be precisely matched, achieving visual and precise adjustment. Furthermore, the ball bearings 413 at the bottom of the drive plate 403 contact the surface of the base 1. The sliding friction between the drive plate 403 and the base 1 is converted into rolling friction, significantly reducing the resistance during adjustment and making the movement of the positioning plate 404 smoother. After all the positioning plates 404 are adjusted to a position suitable for the size of the substrate, the substrate to be printed is placed in the printing area in the center of the base 1. At this time, the edge of the substrate contacts the rubber pads A405 on the outside of the positioning plates 404. The flexible material of the rubber pads A405 can prevent the positioning plates 404 from causing hard compression damage to the edge of the substrate. At the same time, the friction of the rubber enhances the adhesion stability between the substrate and the positioning plates 404, preventing the substrate from shifting during subsequent printing. If the substrate to be printed is thick, a rubber pad B40 can be placed on the surface of the rubber pads A405. 8. Insert the arc of the rubber pad B408 surface into the circular groove 406 on the surface of the rubber pad B408 for fixation, thereby further improving the positioning effect of the substrate to be printed. After the substrate is positioned, start the printing process. The squeegee scrapes from one end of the printing plate 3 to the other end at a uniform speed. The squeegee pressure makes the printing plate 3 and the substrate adhere to each other at the moment of scraping. During this process, the positioning plate 404 always maintains the positioning state of the substrate, ensuring that the substrate will not shift due to the pushing force of the squeegee or the adhesion pressure of the printing plate 3. At the same time, the stable support of the base 1 and the fixing effect of the frame 2 on the printing plate 3 ensure that the relative position of the printing plate 3 and the substrate always meets the reference requirements of the printing pattern. The ink can accurately pass through the mesh of the image part of the printing plate 3 and be printed on the surface of the substrate.
