Technical Field

[0001] This utility model relates to the field of wine box printing technology, specifically a screen printing drying and correction device for wine box printing. Background Technology

[0002] Screen printing equipment refers to a device that uses a screen as a base and produces a screen printing plate with images and text through a photosensitive plate-making method. It is an important production equipment in the modern printing industry. Usually, multiple drying processes are required during the screen printing process to obtain printed products with rich colors.

[0003] In response, Chinese patent application number CN202122246587.2 discloses a screen printing drying and correction device for wine box printing. The device includes a worktable with conical rubber supports fixedly connected to its four bottom corners. A conveying mechanism is horizontally arranged on the top of the worktable. Side plates are symmetrically fixedly connected to the front and rear sides of the top of the worktable. A support mechanism is longitudinally arranged at the rear end of the middle of the back of the worktable. A driving mechanism is located at the upper end of the support mechanism, and a printing squeegee is located at the lower end of the driving mechanism. Rectangular adjustment slots are respectively opened on the top of the two side plates, and drive seats are respectively arranged at the left and right ends of the top of the two side plates. This screen printing drying and correction device for wine box printing, through the cooperation of the L-shaped connecting block, through hole, limiting connecting post, and return spring, facilitates automatic reset of the screen printing plate. No manual lifting is required after each printing cycle, saving time and improving work efficiency.

[0004] The device uses a reset spring to automatically reset the screen printing plate. However, in actual use, the screen printing plate may stick to the paper box. Therefore, when the screen printing plate resets, it will cause the paper box to move upward, causing the paper box to shift on the conveying mechanism, which will affect the subsequent processing effect of the paper box.

[0005] Therefore, in order to solve the above problems, a screen printing drying and correction device for wine box printing is proposed. Utility Model Content

[0006] The purpose of this utility model is to provide a screen printing drying and correction device for wine box printing, so as to solve the problem mentioned in the background art that the device can automatically reset the screen printing plate by setting a reset spring, but in actual use, the screen printing plate will stick to the paper box. Therefore, when the screen printing plate is reset, it will drive the paper box to move upward, causing the paper box to deviate on the conveying mechanism, which will affect the subsequent processing effect of the paper box.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a screen printing drying and correction device for wine box printing, comprising: a box body, a conveyor belt installed on the top surface of the box body, an mounting frame installed at the rear end of the top surface of the conveyor belt, and a blower installed on the front side of the bottom end of the mounting frame;

[0008] The mounting frame is equipped with a positioning structure, which includes a cylinder. The cylinder is fixedly mounted on the top surface of the mounting frame. A connecting column is fixedly connected to the extended end of the cylinder. A mounting plate is connected to the upper end of the side wall of the connecting column. Pressure plates are inserted into both ends of the mounting plate. A first spring is fixedly connected to the upper end of the pressure plate. A connecting frame is connected to the lower end of the side wall of the connecting column. A stop rod is inserted into the end of the connecting frame. A second spring is fixedly connected to the bottom surface of the connecting frame. A printing scraper is installed at the bottom end of the connecting column. A fixing block is installed on the top surface of the conveyor belt. A threaded rod is movably mounted on the inner side of the fixing block through a bearing. A motor is installed on the rear wall of the fixing block. A moving block is slidably mounted on the inner side of the fixing block. A screen printing plate is passed through the surface of the moving block. A third spring is fixedly connected to the top surface of the moving block.

[0009] Preferably, the pressure plate is located outside the fixing block, and the first spring is sleeved on the outside of the pressure plate and fixedly connected to the mounting plate.

[0010] Preferably, the abutment is located on the upper side of both the front and rear ends of the screen printing plate, the second spring is sleeved on the outside of the abutment, and one end of the second spring is fixedly connected to the connecting frame.

[0011] Preferably, the output end of the motor is fixedly connected to the threaded rod, and the threaded rod is threadedly connected to the moving block.

[0012] Preferably, the third spring is sleeved on the outside of the screen printing plate, and one end of the third spring is fixedly connected to the moving block.

[0013] Preferably, the screen printing plate is located on the front side of the hair dryer.

[0014] Compared with the prior art, the beneficial effects of this utility model are: by setting a pressure plate, this utility model can ensure that the pressure plate is always in contact with the cardboard before the screen printing plate moves away from the cardboard, which can limit the cardboard and fix its position on the conveyor belt, avoid positional deviation, and ensure printing quality.

[0015] This invention features a positioning structure. A starting cylinder drives a connecting column, which in turn moves a pressure plate downwards onto the top surface of the cardboard, fixing it to the top of the conveyor belt. As the connecting column descends, the pressure plate moves on the mounting plate, pulling the first spring and causing the abutment rod to press downwards against the top edge of the screen printing plate. As the connecting column moves, it pushes the screen printing plate downwards via the abutment rod, causing the plate to move downwards on the moving block surface and compress the third spring, thus pressing the screen printing plate against the cardboard. The abutment rod then moves on the connecting frame, stretching the second spring, allowing the printing squeegee to adhere to the screen printing plate and print on the cardboard. After completion, the cylinder retracts, raising the connecting column and causing the printing squeegee to move upwards away from the screen printing plate. The second spring returns to its original position, and the abutment rod resets on the connecting frame. The screen printing plate then resets under the elastic force of the third spring, moving away from the cardboard, while the pressure plate remains in contact with the cardboard. This limits the cardboard's position, preventing the screen printing plate from lifting and displacing it, ensuring a fixed position and optimal processing results. Attached Figure Description

Pressure plates 24 are inserted into both ends of the mounting plate 23. A first spring 25 is fixedly connected to the upper end of the pressure plate 24. A connecting frame 26 is connected to the lower end of the side wall of the connecting column 22. A stop rod 27 is inserted into the end of the connecting frame 26. A second spring 28 is fixedly connected to the bottom surface of the connecting frame 26. A printing scraper 29 is installed at the bottom end of the connecting column 22 for conveying. A fixed block 210 is installed on the top surface of the conveyor belt 11. A threaded rod 211 is movably installed on the inner side of the fixed block 210 via a bearing. A motor 212 is installed on the rear wall of the fixed block 210. A movable block 213 is slidably installed on the inner side of the fixed block 210. A screen printing plate 214 is passed through the surface of the movable block 213. A third spring 215 is fixedly connected to the top surface of the movable block 213. The pressure plate 24 ensures that the screen printing plate 214 is always in contact with the cardboard before it moves away from the cardboard. This limits the position of the cardboard on the conveyor belt 11, prevents positional deviation, and ensures printing quality.

[0025] Furthermore, the pressure plate 24 is located outside the fixing block 210, and the first spring 25 is sleeved on the outside of the pressure plate 24 and fixedly connected to the mounting plate 23. The pressure plate 24 can fix the cardboard, and the first spring 25 provides power for the pressure plate 24 to reset on the mounting plate 23.

[0026] Furthermore, the abutment 27 is located on the upper side of the front and rear ends of the screen printing plate 214, and the second spring 28 is sleeved on the outside of the abutment 27. One end of the second spring 28 is fixedly connected to the connecting frame 26, and the second spring 28 provides power for the reset of the abutment 27.

[0027] Furthermore, the output end of the motor 212 is fixedly connected to the threaded rod 211, and the threaded rod 211 is threadedly connected to the moving block 213. The motor 212 can drive the threaded rod 211 to rotate, and the rotation of the threaded rod 211 can drive the moving block 213 to move on the fixed block 210.

[0028] Furthermore, a third spring 215 is sleeved on the outside of the screen printing plate 214, and one end of the third spring 215 is fixedly connected to the moving block 213. The third spring 215 provides power for the screen printing plate 214 to reset on the moving block 213.

[0029] Furthermore, the screen printing plate 214 is located in front of the blower 12, which can dry the printed area of ​​the screen printing plate 214 on the cardboard.

[0030] Working principle: When in use, the cardboard is conveyed on the conveyor belt 11. When the motor 212 is started, it can drive the threaded rod 211 to rotate. The threaded rod 211 is threadedly connected to the moving block 213. The rotation of the threaded rod 211 drives the screen printing plate 214 to move through the moving block 213, and the printing position can be adjusted back and forth.

[0031] The cylinder 21 is activated, which drives the connecting column 22. The connecting column 22 drives the pressure plate 24 to press down on the top surface of the cardboard, thus fixing the cardboard to the top surface of the conveyor belt 11. As the connecting column 22 descends, the pressure plate 24 moves on the mounting plate 23 and pulls the first spring 25. The abutment rod 27 moves downward to meet the top edge of the screen printing plate 214. When the connecting column 22 moves, it pushes the screen printing plate 214 downward through the abutment rod 27. The screen printing plate 214 moves downward on the surface of the moving block 213 and squeezes the third spring 215. The screen printing plate 214 then meets the cardboard. Then the abutment rod 27 moves on the connecting frame 26 and stretches the second spring 28. The printing squeegee 29 then meets the screen printing plate 214 to achieve printing on the cardboard.

[0032] After completion, the control cylinder 21 retracts, causing the connecting column 22 to rise. The printing squeegee 29 then moves upward away from the screen printing plate 214, the second spring 28 returns to its original position, and the stop rod 27 resets on the connecting frame 26. Then, the screen printing plate 214 resets under the elastic action of the third spring 215, and the screen printing plate 214 moves away from the cardboard. The pressure plate 24 remains in contact with the cardboard, which can limit the cardboard and prevent the screen printing plate 214 from lifting and displacing the cardboard. This ensures that the cardboard is fixed in position and guarantees the processing effect. The blower 12 is then started to dry the printed area of ​​the cardboard.
