Abstract
Description
Technical Field
[0001] This utility model relates to the field of printing plate technology, and in particular to a quick printing plate changing device for a printing press. Background Technology
[0002] A printing press is a machine for printing text and images. Modern printing presses generally consist of mechanisms for plate mounting, inking, printing, and paper feeding (including folding). The printing plate is an essential part of the printing press and plays a crucial role in printing text and images.
[0003] Currently, printing plates are typically installed using multiple sets of bolts, which results in slow installation or removal speeds and reduces the efficiency of plate replacement.
[0004] Meanwhile, the screen in the printing plate is usually fixed and the tension of the screen cannot be adjusted. This means that the screen cannot adjust the printing diameter according to the size of the ink particles, or the screen may loosen after long-term use, resulting in thick or uneven ink thickness during the printing process, which affects the printing quality of the item.
[0005] Therefore, we propose a quick plate changing device for printing presses to solve the problems mentioned above. Utility Model Content
[0006] By using a fixed socket to fit and connect the printing plate mounting plate, the screen printing plate can be quickly replaced, improving the efficiency of screen printing plate replacement. At the same time, the tension of the screen can be adjusted by using the inclined plate and push plate to push and stretch the screen, which can prevent excessive ink printing thickness and improve the printing quality of the items, thus solving the problems mentioned in the background art.
[0007] To achieve the above objectives, the present invention adopts the following technical solution: including a screen printing plate, a tension adjustment mechanism, and a quick replacement mechanism. The quick replacement mechanism includes a fixed socket, which is used to fix and splice the screen printing plate, thereby improving the efficiency of screen printing plate replacement.
[0008] The tension adjustment mechanism includes a push plate and an inclined plate. The rear surface of the inclined plate is fixedly connected to the front surface of the push plate. The inclined plate and the push plate are used to adjust the tension of the screen, thereby improving the printing quality of the items.
[0009] Preferably, the quick-change mechanism further includes a bearing plate, the side surface of which is movably connected to a connecting plate via a bearing, and the lower surface of the connecting plate is fixedly connected to the upper surface of the fixed socket. Rubber seats are provided on both sides of the fixed socket.
[0010] Preferably, the tension adjustment mechanism further includes two sets of baffles, the lower and upper surfaces of the two sets of baffles being fixedly connected to the upper and lower surfaces of the push plate, and magnets being provided on the rear surfaces of the two sets of baffles.
[0011] Preferably, a printing plate mounting plate is fixedly connected to the rear surface of the screen printing plate, and the upper surface of the printing plate mounting plate is fitted into a fixed socket. A splicing plate is fixedly connected to the rear surface of the printing plate mounting plate, and a movable seat is fitted into the rear surface of the splicing plate. The upper surface of the movable seat is fixedly connected to the lower surface of the bearing plate.
[0012] Preferably, both sides of the movable seat are movably connected to concave seats via bearings, and a threaded plate is fixedly connected to the rear surface of the concave seat, with a threaded rod connected to the internal thread of the threaded plate.
[0013] Preferably, the screen printing plate has a screen inside, a support plate is fixedly connected to the upper surface of the screen printing plate, and the support plate is slidably connected to the push plate. An extrusion seat is fixedly connected to the upper surface of the screen printing plate, and the interior of the extrusion seat is fitted and connected to the inclined plate.
[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0015] 1. In this utility model, the screen printing plate can be positioned by the interlocking connection between the splicing plate and the movable seat. By moving the connecting plate, the connecting plate moves downward, causing the fixed socket to swing downward, so that the lower surface of the fixed socket can extend into the interior of the printing plate mounting plate. The rubber seat can increase the friction between the fixed socket and the printing plate mounting plate during the interlocking connection, thereby improving the stability of the fixed socket and the printing plate mounting plate during the interlocking. When the lower part of the fixed socket is interlocked into the interior of the mounting base, the screen printing plate can be fixed in both directions in conjunction with the interlocking of the splicing plate and the movable seat. In the reverse operation, the screen printing plate can be disassembled, thereby improving the efficiency of screen printing plate replacement.
[0016] 2. In this invention, the top of the screen printing plate extends through the interior of the screen printing plate. By sliding the support plate and the push plate, the push plate can move the inclined plate together. Since the surface of the inclined plate is in contact with the surface of the screen, when the push plate moves, the inclined plate can push the screen into the interior of the extrusion seat, allowing the screen to extend out from the interior of the extrusion seat. The tension of the screen can be adjusted according to the position of the inclined plate pushing the screen. Through the continuous movement of the push plate, the magnet can attract the support plate to fix the push plate, thereby improving the printing quality of the screen printing plate.

[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention can also be implemented in other ways than those described herein, and therefore the present invention is not limited to the specific embodiments disclosed in the following specification.
[0024] Example 1, as shown in the attached document Figure 1 - Figure 4 As shown, it includes a screen printing plate 1, a tension adjustment mechanism 4 and a quick replacement mechanism 11. The quick replacement mechanism 11 includes a fixed socket 113, which is used to fix and splice the screen printing plate 1, thereby improving the replacement efficiency of the screen printing plate 1.
[0025] The tension adjustment mechanism 4 includes a push plate 401 and an inclined plate 404. The rear surface of the inclined plate 404 is fixedly connected to the front surface of the push plate 401. The inclined plate 404 and the push plate 401 are used to adjust the tension of the screen 3, thereby improving the printing quality of the items.
[0026] The overall effect of Embodiment 1 is as follows: by using the fixed socket 113 to fit and connect the printing plate mounting plate 12, the screen printing plate 1 can be quickly replaced, improving the replacement efficiency of the screen printing plate 1. At the same time, by using the inclined plate 404 and the push plate 401 to push and stretch the screen 3, the tension of the screen 3 can be adjusted, which can prevent the ink printing thickness from being too large and improve the printing quality of the items.
[0027] Example 2, as Figure 1 - Figure 3 As shown, the quick-change mechanism 11 also includes a bearing plate 112. A connecting plate 111 is movably connected to the side surface of the bearing plate 112 via bearings. The lower surface of the connecting plate 111 is fixedly connected to the upper surface of the fixed socket 113. Rubber seats 114 are provided on both sides of the fixed socket 113. A printing plate mounting plate 12 is fixedly connected to the rear surface of the screen printing plate 1. The upper surface of the printing plate mounting plate 12 is fitted into the fixed socket 113. A splicing plate 10 is fixedly connected to the rear surface of the printing plate mounting plate 12. A movable seat 9 is fitted into the rear surface of the splicing plate 10. The upper surface of the movable seat 9 is fixedly connected to the lower surface of the bearing plate 112. A concave seat 8 is movably connected to both sides of the movable seat 9 via bearings. A threaded plate 6 is fixedly connected to the rear surface of the concave seat 8. A threaded rod 7 is threadedly connected to the inside of the threaded plate 6.
[0028] The overall effect of embodiment 2 is as follows: Tightening the threaded rod 7 allows the screen printing plate 1 to be installed at the printing position of the printing machine; the interlocking connection between the splicing plate 10 and the movable seat 9 positions the screen printing plate 1; the movement of the connecting plate 111 causes the fixed socket 113 to swing downwards, allowing the lower surface of the fixed socket 113 to extend into the interior of the printing plate mounting plate 12; and the rubber seat 114 improves the friction between the fixed socket 113 and the printing plate mounting plate 12 during the interlocking connection. The friction enhances the stability of the fixed socket 113 when it is fitted into the printing plate mounting plate 12. When the lower part of the fixed socket 113 is fitted into the interior of the mounting base, it can fix the screen printing plate 1 in both directions in conjunction with the fitting of the splicing plate 10 and the movable base 9. In reverse operation, the screen printing plate 1 can be disassembled, thereby improving the replacement efficiency of the screen printing plate 1. After the screen printing plate 1 is installed, the movement of the concave base 8 and the movable base 9 makes it convenient to pick up or place the printed objects below the screen printing plate 1.
[0029] Example 3, as Figure 1 and Figure 4As shown, the tension adjustment mechanism 4 also includes two sets of baffles 403. The lower and upper surfaces of the two sets of baffles 403 are fixedly connected to the upper and lower surfaces of the push plate 401. Magnets 402 are provided on the rear surfaces of the two sets of baffles 403. A screen 3 is provided inside the screen printing plate 1. A support plate 2 is fixedly connected to the upper surface of the screen printing plate 1, and the support plate 2 is slidably connected to the push plate 401. An extrusion seat 5 is fixedly connected to the upper surface of the screen printing plate 1, and the interior of the extrusion seat 5 is fitted and connected to the inclined plate 404.
[0030] The effect achieved by the entire embodiment 3 is as follows: When the screen printing plate 1 is in use, the top of the screen 3 passes through the interior of the screen printing plate 1. By sliding the support plate 2 and the push plate 401, the push plate 401 can drive the inclined plate 404 to move together. Since the surface of the inclined plate 404 is in contact with the surface of the screen 3, when the push plate 401 moves, the inclined plate 404 can push the screen 3 into the interior of the extrusion seat 5, so that the screen 3 can extend out from the interior of the extrusion seat 5. The tension of the screen 3 can be adjusted according to the position of the inclined plate 404 pushing the screen 3. By continuously moving the push plate 401, the magnet 402 can attract the support plate 2 to fix the push plate 401, thereby improving the printing quality of the screen printing plate 1.
[0031] The working principle of the entire device is as follows: Tightening the threaded rod 7 can install the screen printing plate 1 at the printing position of the printing machine. The screen printing plate 1 can be positioned by the interlocking connection of the splicing plate 10 and the movable seat 9. By moving the connecting plate 111, the connecting plate 111 is driven downward to swing the fixed socket 113 downward, so that the lower surface of the fixed socket 113 can extend into the interior of the printing plate mounting plate 12. The rubber seat 114 can increase the friction between the fixed socket 113 and the printing plate mounting plate 12 when they are interlocked, thus improving the stability of the fixed socket 113 when it is interlocked with the printing plate mounting plate 12. When the lower part of the fixed socket 113 is interlocked into the interior of the mounting seat, the screen printing plate 1 can be fixed in both directions in conjunction with the interlocking of the splicing plate 10 and the movable seat 9.
[0032] The screen 3 extends through the interior of the screen printing plate 1. By sliding the support plate 2 and the push plate 401, the push plate 401 can move the inclined plate 404 together. Since the surface of the inclined plate 404 is in contact with the surface of the screen 3, when the push plate 401 moves, the inclined plate 404 can push the screen 3 into the interior of the extrusion seat 5, allowing the screen 3 to extend out from the interior of the extrusion seat 5. The tension of the screen 3 can be adjusted according to the position of the inclined plate 404 pushing the screen 3. As the push plate 401 moves continuously, the magnet 402 can attract the support plate 2 to fix the push plate 401. Ink is poured onto the surface of the screen 3, and the printing press can print on the object using the squeegee. The movement of the concave seat 8 and the movable seat 9 makes it easy to pick up or place the printed object below the screen printing plate 1, thus completing the printing of the object.
[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
