Description

Technical Field

[0001] This utility model relates to the field of paper processing, and in particular to a paper printing device for paper processing. Background Technology

[0002] Paper processing is the process of altering the properties, appearance, or assigning specific functions to base paper or paperboard through a series of processes. Paper printing equipment, as a key piece of equipment in paper processing, plays a vital role in this field. It transfers colorful and diverse designs onto the paper surface using various technologies such as screen printing, digital inkjet printing, and flexographic printing. Whether it's exquisite packaging paper, highly personalized decorative paper, or artistic calligraphy and painting paper, all rely on the support of paper printing equipment. This equipment not only enhances the aesthetics and added value of paper but also meets the diverse and personalized needs of different industries.

[0003] However, current paper printing equipment for paper processing has the following drawbacks: First, the printing screen is inconvenient to disassemble. For example, if it is fixed with screws, multiple screws must be unscrewed each time, which is cumbersome and time-consuming. Moreover, after frequent use, the screw threads are prone to wear and tear, resulting in stripping. This causes the printing screen to get stuck in the printing plate frame and difficult to remove, seriously affecting the printing progress and efficiency. It is also difficult for operators to quickly change screens of different patterns and sizes, affecting the ease of use of the equipment. Second, the paper positioning function is limited, only adapting to specific specifications and unable to effectively position different sizes of paper, resulting in insufficient equipment versatility and difficulty in meeting diverse production needs.

[0004] In response to this technical problem, this application proposes a paper printing device for paper processing. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a paper printing device for paper processing. This device aims to make the printing screen easy to disassemble, thereby facilitating the replacement of printing screens with different patterns and sizes by workers, improving the convenience of the equipment, and enabling the equipment to position paper of different sizes, thus enhancing its versatility.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A paper printing device for paper processing includes a base, with columns fixedly connected to the four corners of the top side of the base. A top plate is fixedly connected to the top of each of the four columns. A threaded rod is directly rotatably connected to the top plate and the base. A lifting plate is slidably connected to the outer wall of each of the four columns. The left side of the lifting plate is threadedly connected to the outer wall of the threaded rod. A motor is mounted on the top side of the top plate, and the top of the threaded rod is fixedly connected to the drive end of the motor. An outer frame is connected to the middle of the lifting plate via a fixing component, which secures the outer frame to the lifting plate. A printing screen is fixedly connected to the bottom side of the outer frame. A positioning component is provided on the bottom side of the lifting plate to position the paper. An adsorption component is provided inside the base to adsorb the paper.

[0008] Furthermore, the fixing assembly includes multiple grooves formed on the top side of the lifting plate, with a rod slidably connected inside the groove, the end of the rod inserted into the inside of the outer frame, and a ring rotatably connected to the outer wall of the rod.

[0009] Furthermore, the ring is fitted inside the groove, a limiting rod is fixedly connected to the outer wall of the ring, a limiting groove is formed on one side of the groove, and the limiting rod is engaged inside the limiting groove.

[0010] Furthermore, a baffle is slidably connected inside the limiting groove, one side of the baffle is inserted into the inside of the limiting groove, and the baffle is located on the top side of the limiting rod.

[0011] Furthermore, the positioning component includes two sliding grooves formed on the bottom side of the lifting plate, two positioning plates are slidably connected between the two sliding grooves, a first bidirectional screw is rotatably connected inside the front sliding groove, and a round rod is fixedly connected inside the rear sliding groove.

[0027] 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.

[0028] Reference Figure 1 , Figure 3 and Figure 7 This utility model provides an embodiment of a paper printing device for paper processing, comprising a base 1, with columns 6 fixedly connected to the four corners of the top side of the base 1. A top plate 5 is fixedly connected to the top of each of the four columns 6. A threaded rod 3 is directly rotatably connected to the top plate 5 and the base 1. A lifting plate 2 is slidably connected to the outer wall of each of the four columns 6. The left side of the lifting plate 2 is threadedly connected to the outer wall of the threaded rod 3. A motor 4 is installed on the top side of the top plate 5, and the top of the threaded rod 3 is fixedly connected to the drive end of the motor 4. The motor 4 drives the threaded rod 3 to rotate, causing the threaded rod 3 to move the lifting plate 2 up and down. An outer frame 9 is connected to the middle of the lifting plate 2, and a printing screen 10 is fixedly connected to the bottom side of the outer frame 9. By selecting a nylon screen with a suitable mesh size, the hollow portion of the printing pattern is formed. (See reference...) Figure 3 and Figure 4The top side of the lifting plate 2 has multiple grooves. A rod 11 is slidably connected inside each groove. The end of the rod 11 is inserted into the inside of the outer frame 9. A ring 12 is rotatably connected to the outer wall of the rod 11. The ring 12 is fitted inside the groove. A limiting rod 13 is fixedly connected to the outer wall of the ring 12. A limiting groove is formed on one side of the groove. The limiting rod 13 engages inside the limiting groove. A baffle 14 is slidably connected inside the limiting groove. One side of the baffle 14 is inserted into the limiting groove. The baffle 14 is located on the top side of the limiting rod 13. By sliding the rod 11, it is inserted into the outer frame 9, thereby fixing the printing screen 10 to the lifting plate 2. The moving ring 12 rotates the limiting rod 13 into the limiting groove to prevent the insert rod 11 from detaching from the outer frame 9. At the same time, the sliding baffle 14 inserts the limiting rod 13 into the limiting groove, thus preventing it from falling out of the limiting groove. This makes it easy to disassemble the printing screen, which makes it convenient for staff to change printing screens of different patterns and sizes, improving the convenience of the equipment. The multiple grooves on the lifting plate 2 allow the lifting plate 2 to fix printing screens 10 of different sizes as needed. That is, when it is necessary to fix the printing screen 10, only the insert rods 11 at the four corners of the outer frame 9 need to be inserted into them, and the other insert rods 11 do not need to be inserted.

[0029] Reference Figure 2 , Figure 5 and Figure 6The lifting plate 2 has two sliding grooves on its bottom side, and two positioning plates 17 are slidably connected between the two sliding grooves. The front sliding groove is rotatably connected to a first bidirectional screw 15, and the rear sliding groove is fixedly connected to a round rod 16. One end of the positioning plate 17 is threaded to the outer wall of the first bidirectional screw 15, and the other end of the positioning plate 17 is slidably connected to the outer wall of the round rod 16. The right side of the lifting plate 2 is rotatably connected to a first knob 22 through a damping shaft. The right end of the first bidirectional screw 15 is fixedly connected to the inside of the first knob 22. By rotating the first knob 22, the two positioning plates 17 slide to the left and right sides of the outer frame 9 respectively, thereby restricting the paper in the outer frame 9 and thus performing preliminary positioning of the paper. Both positioning plates 17 have strip grooves on their adjacent sides. A second bidirectional screw 18 is rotatably connected inside the strip groove. Two sliders 19 are threadedly connected to the outer wall of the second bidirectional screw 18. The sliders 19 are slidably connected inside the strip groove. A clamping plate 20 is connected to one side of the slider 19 via a torsion spring. A second knob 21 is rotatably connected to the front side of the positioning plate 17 via a damping shaft. The front end of the second bidirectional screw 18 is fixedly connected inside the second knob 21. By rotating the second knob 21, the second bidirectional screw 18 is rotated, causing the second bidirectional screw 18 to drive the two sliders 19 to slide in relative or opposite directions. The torsion spring causes the clamping plate 20 to rotate towards the paper, thereby clamping the paper onto the base 1. This positions the four corners of the paper and allows the device to position paper of different sizes, improving the versatility of the device. The base 1 has multiple adsorption holes on its top side and an adsorption cavity on its top side inside. The adsorption holes and the adsorption cavity are connected. A vacuum pump 8 is installed inside the base 1. The vacuum pump 8 and the adsorption cavity are connected by a pipe 7. The vacuum pump 8 and the pipe 7 provide a vacuum environment for the adsorption cavity and adsorption holes, so that the base 1 adsorbs the paper onto the table surface, thereby achieving full positioning of the paper.

[0030] Working principle: First, as needed, the printing screen 10 with a suitable pattern is fixed onto the lifting plate 2. When this step is required, the outer frame 9 is placed into the lifting plate 2, aligning the four corners of the outer frame 9 with the grooves. Then, the sliding rod 11 is inserted into the outer frame 9, thus fixing the printing screen 10 onto the lifting plate 2. The limiting rod 13 is rotated into the limiting groove by rotating the ring 12 to prevent the rod 11 from detaching from the outer frame 9. At the same time, the sliding baffle 14 is inserted into the limiting groove to prevent the limiting rod 13 from falling out of the limiting groove. The disassembly process is the reverse of the above and will not be described in detail here. Then, the paper is placed on the base 1, and the motor 4 is started. The motor 4 drives the threaded rod 3 to rotate, causing the threaded rod 3 to move the lifting plate 2 downward, so that the printing screen 10 and the paper come into contact with each other. Then, the first knob 22 is rotated to make the two positioning plates 17 slide to the left and right sides of the outer frame 9 respectively, thereby restricting the paper. In the outer frame 9, the paper is initially positioned. Then, the second knob 21 is turned to rotate the second bidirectional screw 18, which drives the two sliders 19 to slide in opposite or relative directions. The torsion spring causes the clamping plate 20 to rotate towards the paper, thus clamping the paper onto the base 1 and positioning the four corners of the paper. The vacuum pump 8 is then started, and the vacuum pump 8 and the pipe 7 provide a vacuum environment for the adsorption chamber and adsorption holes, allowing the base 1 to adsorb the paper onto the table, thus positioning the paper comprehensively. Then, an appropriate amount of printing ink is poured onto the printing screen 10. The operator then uses a scraper or other scraper to scrape the printing ink on the printing screen 10, transferring the ink through the perforated parts of the printing screen 10 onto the paper, completing one printing operation. Then, the motor 4 is started to move the lifting plate 2 upward, and the vacuum pump 8 is turned off. Finally, the paper is removed to complete the printing work.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
