Description

Technical Field

[0001] This utility model relates to the field of screen printing technology, specifically a screen printing device. Background Technology

[0002] A screen printing machine is a mechanical device used for screen printing. Its core is to achieve precise printing operations and efficient production processes. It is suitable for various materials such as paper, plastic, textiles, and ceramics. It can print on both flat and curved surfaces, has the ability to print large quantities of products quickly, and the pigments used are usually environmentally friendly, with minimal impact on the environment.

[0003] However, most screen printing equipment is prone to screen misalignment due to displacement during repeated printing. This can lead to character halo after printing, resulting in blurry patterns on the printed product and lower printing quality. This makes screen printing equipment inconvenient for repeated printing. Utility Model Content

[0004] The purpose of this invention is to provide a screen printing device to solve the problem of misalignment that easily occurs during the use of the screen printing device mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a screen printing device, comprising a base, a placement plate, a processing plate, an adjusting seat, a mounting seat, a clamping plate, a printing plate, and a coating plate. The placement plate is provided at the top of the base, the processing plate is provided at one end of the base, the adjusting seat is provided on one side of the processing plate, the mounting seats are provided on both sides of the adjusting seat, the clamping plate is provided on one side of the mounting seat, the printing plate is provided on the side of the adjusting seat near the mounting seat, the coating plate is provided on one side of the printing plate, and a fixing frame is provided at the top of the clamping plate.

[0006] Preferably, the fixed frame is internally threaded with a first threaded rod, a rotating handwheel is connected to one side of the first threaded rod, and a handle is provided at the end of the rotating handwheel away from the first threaded rod.

[0007] Preferably, the surface of the first threaded rod is threadedly connected to a pressing seat, and the bottom end of the pressing seat is provided with a movable seat, the movable seat and the pressing seat being trapezoidal in shape.

[0008] Preferably, the clamping plate is provided inside the clamping plate, and the clamping plate is connected to the movable seat by symmetrically distributed connecting rods.

[0009] Preferably, a reset spring that is welded to the fixed frame is provided on the side of the bottom of the movable seat near the connecting rod.

[0010] Preferably, the reset springs are symmetrically distributed inside the fixed frame.

[0011] Preferably, a control seat is provided on the side of the base near the placement plate, and a drive motor is installed on one side of the control seat.

[0012] Preferably, the output end of the drive motor is connected to a second threaded rod via a coupling, and a displacement block is threadedly connected to the surface of the second threaded rod.

[0013] Preferably, both ends of the displacement block are provided with welded guide rods, and a guide groove is provided inside the control seat on the side near the guide rod.

[0014] Preferably, one end of the displacement block is provided with a welded movable rod, and the end of the movable rod away from the displacement block is connected to a cleaning brush.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This screen printing device, by rotating the handwheel, allows the connected first threaded rod to push the moving seat through the extrusion seat, thereby allowing the moving seat to move the clamping plate through the connecting rod, so that the clamping force is the same when the screen is clamped, avoiding the misalignment caused by different clamping forces due to multiple locking seats during movement. Starting the drive motor allows the second threaded rod connected to the output end to move the moving rod through the displacement block, so that the moving rod can clean the surface of the placement plate through the cleaning brush, thus avoiding excessive surface impurities when the screen printing device is in use.

[0016] 1. In this screen printing device, when the screen printing device is in use, multiple locking seats are required to lock the screen, which makes it difficult to generate the same squeezing force during tightening. This makes it easy for the screen to deviate during movement, resulting in halo effect on the characters during screen printing. By rotating the rotating handwheel, the first threaded rod connected to it can be rotated. The first threaded rod can push the moving seat through the squeezing seat, and the moving seat can move the clamping plate through the connecting rod. This allows the clamping plate to clamp the screen, ensuring that the clamping force is the same when the screen is clamped. This avoids the problem of different clamping forces caused by multiple locking seats, which can lead to deviation during movement. Therefore, the screen printing device has a better stable limiting effect during use.

[0017] 2. In this screen printing device, when it is in use, a lot of impurities tend to adhere to the surface during placement, making subsequent printing inconvenient. This can be addressed by starting the drive motor, which rotates the second threaded rod connected to the output end. The rotation of the second threaded rod moves the displacement block connected to the surface thread, which in turn moves the connected moving rod. This moving rod then moves the connected cleaning brush, which cleans the surface of the placement plate. This prevents excessive surface impurities during screen printing, making subsequent printing more convenient. Attached Figure Description

[0023] 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.

[0024] Please see Figures 1-3This utility model provides a technical solution: a screen printing device, including a base 1, a placement plate 2, a processing plate 3, an adjusting seat 4, a mounting seat 5, a clamping plate 6, a printing plate 7, and a coating plate 8. The placement plate 2 is located at the top of the base 1, the processing plate 3 is located at one end of the base 1, the adjusting seat 4 is located on one side of the processing plate 3, mounting seats 5 are located on both sides of the adjusting seat 4, the clamping plate 6 is located on one side of the mounting seat 5, the printing plate 7 is located on the side of the adjusting seat 4 near the mounting seat 5, the coating plate 8 is located on one side of the printing plate 7, and a fixing frame 9 is located at the top of the clamping plate 6. The fixing frame 9 is internally threaded with a first... A threaded rod 10 is provided, with a rotating handwheel 11 connected to one side of the first threaded rod 10. A handle is provided at the end of the rotating handwheel 11 away from the first threaded rod 10. A pressing seat 12 is threadedly connected to the surface of the first threaded rod 10. A movable seat 13 is provided at the bottom end of the pressing seat 12. The movable seat 13 and the pressing seat 12 are trapezoidal in shape. A clamping plate 14 is provided inside the clamping plate 6. A symmetrically distributed connecting rod 15 is connected between the clamping plate 14 and the movable seat 13. A return spring 16 is provided at the bottom end of the movable seat 13 near the connecting rod 15 and is welded to the fixed frame 9. The return spring 16 is symmetrically distributed inside the fixed frame 9.

[0025] In practice,

[0026] See Figures 1-3 It is known that when the screen printing device is in use, multiple locking seats are required to lock the screen, making it difficult to generate the same extrusion force during tightening. This can easily cause the screen to shift during movement, resulting in character halos during printing. This can be addressed by rotating the handwheel 11, which in turn rotates the connected first threaded rod 10. This, in turn, moves the threaded pressing seat 12, thus... When the extrusion seat 12 moves, it can push the movable seat 13 at the bottom, so that the movable seat 13 can move the connected connecting rod 15, and the connected clamping plate 14 can move when the connecting rod 15 moves. This allows the clamping plate 14 to clamp the screen placed inside the clamping plate 6 when it moves, so that the clamping force is the same when the screen is clamped. This avoids the misalignment caused by different clamping forces due to multiple locking seats during movement, thus enabling the screen printing device to have a better stable limiting effect during use.

[0027] A control seat 17 is provided on the side of the base 1 near the placement plate 2. A drive motor 18 is installed on one side of the control seat 17. The output end of the drive motor 18 is connected to a second threaded rod 19 via a coupling. A displacement block 20 is threadedly connected to the surface of the second threaded rod 19. Both ends of the displacement block 20 are provided with welded guide rods 21. A guide groove 22 is provided inside the control seat 17 on the side near the guide rod 21. A moving rod 23 is provided at one end of the displacement block 20. A cleaning brush 24 is connected to the end of the moving rod 23 away from the displacement block 20.

[0028] In practice,

[0029] See Figure 1 and Figure 4 It is known that when a screen printing device is in use, it is easy for a lot of impurities to adhere to the surface during placement, which makes subsequent printing inconvenient. By starting the drive motor 18, the drive motor 18 can rotate the second threaded rod 19 connected to the output end. When the second threaded rod 19 rotates, it can move the displacement block 20 connected to the surface thread. When the displacement block 20 moves, it can drive the connected moving rod 23 to move. When the moving rod 23 moves, it can move the connected cleaning brush 24. In turn, the cleaning brush 24 can clean the surface of the placement plate 2, so that the screen printing device can avoid a lot of surface impurities during use. When the displacement block 20 moves, it can move the connected guide rod 21, so that the guide rod 21 can slide in the opened guide groove 22, making subsequent printing more convenient.

[0030] In summary, a screen printing device is a mechanical device used for screen printing. Its core lies in achieving precise printing operations and efficient production processes. It is suitable for various materials such as paper, plastics, textiles, and ceramics. By rotating the handwheel 11, the handwheel 11 rotates the connected first threaded rod 10, which in turn pushes the moving seat 13 through the pressing seat 12. The moving seat 13 then moves the clamping plate 14 through the connecting rod 15, thereby clamping the screen with the clamping plate 14. This ensures that the clamping force is uniform when the screen is held, avoiding the misalignment caused by different clamping forces from multiple locking seats. This results in a stable and limiting effect for the screen printing device during use.
