[0002] A screen printing machine is a machine that uses a screen printing plate to apply printing. It is a type of printing machine that prints text and images. It is a general term for machines or equipment used to produce printed materials. Screen printing machines are a representative type of printing equipment among stencil printing machines. In addition to silk, the materials used to make screens can also be nylon, copper, steel, or stainless steel wire. They can be divided into flat screen printing machines, curved screen printing machines, rotary screen printing machines, etc.

[0003] However, some screen printing machines require changing screen printing plates with different patterns when screen printing different products. However, screen printing plates are usually fixed in the printing plate frame by the cooperation of screws and screw holes, which makes the disassembly and replacement of screen printing plates cumbersome. Therefore, this does not meet the current needs. In response, we have proposed a screen printing machine that makes it easy to replace screens. Utility Model Content

[0004] The purpose of this utility model is to provide a screen printing machine that facilitates screen replacement, in order to solve the problem mentioned in the background art that screen printing machines need to change screen printing plates with different patterns when screen printing different products. However, screen printing plates are generally fixed in the printing plate frame by the cooperation between screws and screw holes, which makes the disassembly and replacement of screen printing plates cumbersome.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a screen printing machine that facilitates screen replacement, comprising a worktable and a screen printing plate. A drive box is fixedly installed on one side of the upper end of the worktable. A linear motor is connected to the front surface of the drive box via a motor drive. A movable seat is movably connected to one side of the linear motor. Cylinders are fixedly connected to both sides of the upper end of the movable seat. A printing squeegee is driven by one cylinder on one side, and a return ink squeegee is driven by the other cylinder on the other side. Limit seats are fixedly connected to both ends of the linear motor. Sliding grooves are opened on the front sides of the two limit seats. Sliding plates are slidably connected inside the two sliding grooves. Clamping plates are fixedly connected to the bottom ends of the two sliding plates. A screen printing plate is provided between the two clamping plates, and the screen printing plate is located below the printing squeegee and the return ink squeegee.

[0006] Preferably, the upper ends of the two clamping plates, and the rear side of the sliding plate, are rotatably connected to threaded rods via rotating shafts. The upper end of the threaded rods is threaded through the limiting seat and extends to the upper end of the limiting seat.

[0007] Preferably, the inner walls of both clamping plates at the ends away from the sliding plate are provided with grooves, and rollers are rotatably connected inside the two grooves.

[0008] Preferably, the two sides of the screen printing plate are slidably connected to the inside of the two clamping plates, and the outer wall of the screen printing plate is in rolling contact with the roller.

[0009] Preferably, each of the two clamping plates has a movable groove inside its interior at the end away from the groove, and a movable rod extending through and to the outside of the movable groove is movably connected inside the movable groove.

[0010] Preferably, a limiting plate is fixedly connected to the outer surface of the movable rod located inside the movable groove. A spring is fixedly connected between one side of the limiting plate and one side of the inner wall of the movable groove, and the spring is wound around the outer surface of the movable rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model involves sliding the two ends of the screen printing plate into the interior of the clamping plate. Rollers inside the clamping plates make rolling contact with the two ends of the screen printing plate, improving the smoothness of plate extraction. When the screen printing plate is inserted near the top of the clamping plate, the arc surfaces on both sides of the top of the screen printing plate abut against the outer surface of the limiting block. This pushes the limiting block and the movable rod towards the interior of the movable groove, compressing the limiting plate's compression spring. When the screen printing plate is inserted at the top of the clamping plate, the limiting grooves on both sides correspond to the limiting block. The limiting block, pushed by the spring, is inserted into the limiting groove, thus limiting the installation of the screen printing plate. When the screen printing plate needs to be removed, it is simply pulled out. The outer wall of the limiting groove slides against the outer surface of the limiting block, pushing the limiting block to retract back into the movable groove, thus releasing the limitation on the screen printing plate and facilitating its removal.

[0014] 2. This utility model rotates the threaded rods on both sides, so that the threaded rods are threadedly connected to the inside of the limiting seat and rotate at the upper end of the clamping plate. Then, through the sliding limit of the sliding plate and the sliding groove, the clamping plate with the screen printing plate is driven to move up, so that the upper end of the screen printing plate is close to the printing squeegee and the ink return squeegee.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Please see Figures 1 to 4 This utility model provides an embodiment of a screen printing machine that facilitates screen replacement, comprising a worktable 1 and a screen printing plate 8. A drive box 2 is fixedly installed on one side of the upper end of the worktable 1. A linear motor 3 is connected to the front surface of the drive box 2 via a motor drive. A movable seat 4 is movably connected to one side of the linear motor 3. Cylinders 5 are fixedly connected to both sides of the upper end of the movable seat 4. A printing squeegee 6 is driven by one cylinder 5, and a return ink squeegee 7 is driven by the other cylinder 5. Limit seats 9 are fixedly connected to both ends of the linear motor 3. A sliding groove 901 is opened on the front side of each of the two limit seats 9. A sliding plate 11 is slidably connected inside each of the two sliding grooves 901. A clamping plate 10 is fixedly connected to the bottom end of each of the two sliding plates 11. The screen printing plate 8 is provided between the two clamping plates 10, and the screen printing plate 8 is located below the printing squeegee 6 and the return ink squeegee 7.

[0022] The inner walls of the two clamping plates 10 away from the sliding plate 11 are each provided with a groove 1001. Rollers 13 are rotatably connected inside the two grooves 1001. The two sides of the screen printing plate 8 are slidably connected to the inside of the two clamping plates 10, and the outer side of the screen printing plate 8 is in rolling contact with the rollers 13. The smoothness of the screen printing plate 8 is improved by the rolling contact between the rollers 13 inside the clamping plates 10 and the two ends of the screen printing plate 8.

[0023] Both clamping plates 10 have movable grooves 1002 inside the ends away from the grooves 1001. Movable rods 14 extend through and out of the movable grooves 1002 and are movably connected inside the movable grooves 1002. A limiting plate 15 is fixedly connected to the outer surface of the movable rod 14 on one side inside the movable groove 1002. A spring 16 is fixedly connected between one side of the limiting plate 15 and one side of the inner wall of the movable groove 1002 and is wrapped around the outer surface of the movable rod 14. A limiting block 17 is fixedly connected to the end of the movable rod 14 that extends through and out of the movable groove 1002 and is arc-shaped. Limiting grooves 801 are opened on both sides near the top of the screen printing plate 8. The limiting blocks 17 are movably engaged with the corresponding limiting grooves 801. The outer walls of the limiting grooves 801 are arc-shaped and the limiting blocks 17 slide in contact with the outer walls of the limiting grooves 801.

[0024] When it is necessary to disassemble the screen printing plate 8, simply pull out the screen printing plate 8. The outer wall of the limiting groove 801 slides into contact with the outer surface of the limiting block 17, pushing the limiting block 17 to move and retract back into the movable groove 1002, thereby releasing the limitation on the screen printing plate 8 and making it convenient to disassemble the screen printing plate 8.

[0025] The upper ends of the two clamping plates 10, located behind the sliding plate 11, are rotatably connected to threaded rods 12 via rotating shafts. The upper ends of the threaded rods 12 are threaded through the limiting seat 9 and extend to the upper end of the limiting seat 9. By rotating the threaded rods 12 on both sides, the threaded rods 12 are threadedly connected to the inside of the limiting seat 9 and rotate at the upper end of the clamping plate 10. Then, under the sliding limitation of the sliding plate 11 and the slide groove 901, the clamping plate 10 with the screen printing plate 8 is moved upward, so that the upper end of the screen printing plate 8 is close to the printing squeegee 6 and the ink return squeegee 7.

[0026] When the screen printing machine is in use, the two ends of the screen printing plate 8 are slidably inserted into the inside of the clamping plate 10. At this time, the rollers 13 inside the clamping plates 10 make rolling contact with the two ends of the screen printing plate 8, thereby improving the smoothness of the screen printing plate 8 being extracted. Then, when the screen printing plate 8 is inserted near the top end of the clamping plate 10, the arc surfaces on both sides of the top end of the screen printing plate 8 abut against the outer surface of the limiting block 17, and then push the limiting block 17 and the movable rod 14 to move into the movable groove 1002, and drive the limiting plate 15 to compress the spring 16. When the screen printing plate 8 is inserted into the top of the clamping plate 10, the limiting grooves 801 on both sides correspond to the limiting blocks 17. At this time, the limiting blocks 17 are inserted into the limiting grooves 801 under the push of the spring 16, thereby limiting the installation of the screen printing plate 8. When it is necessary to remove the screen printing plate 8, simply pull out the screen printing plate 8. The outer wall of the limiting groove 801 slides into contact with the outer surface of the limiting block 17, pushing the limiting block 17 to move and retract back into the movable groove 1002, thereby releasing the limitation on the screen printing plate 8 and facilitating the removal of the screen printing plate 8.

[0027] After the screen printing plate 8 is installed, by rotating the threaded rods 12 on both sides, the threaded rods 12 are threadedly connected to the inside of the limiting seat 9 and rotated at the upper end of the clamping plate 10. Then, under the sliding limit of the sliding plate 11 and the sliding groove 901, the clamping plate 10 with the screen printing plate 8 is moved upward, so that the upper end of the screen printing plate 8 is close to the printing squeegee 6 and the ink return squeegee 7.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
