Description

Technical Field

[0001] The utility model relates to the technical field of vacuum screen printing machines, in particular to a vacuum screen printing machine. Background Art

[0002] The vacuum screen printer is a highly efficient printing device that is widely used in printing processes such as screen printing ink, varnish and UV oil. Its working principle is to use vacuum negative pressure to adsorb the material on the printing table, and then use a scraper to evenly apply the ink on the surface of the material to achieve high-precision printing.

[0003] Existing vacuum screen printing machines generally require manual placement of the plastic plate to be printed. In order to ensure printing quality, the plastic plate needs to be placed in the center position, which requires manual calibration, is inefficient and prone to errors. Therefore, a vacuum screen printing machine is proposed to address the above problems. Utility Model Content

[0004] The purpose of the present invention is to provide a vacuum screen printing machine to solve the problems raised in the above background technology.

[0005] To achieve the above purpose, the present invention provides the following technical solutions:

[0006] A vacuum screen printing machine includes a vacuum screen printing machine base and a vacuum adsorption table. The top of the vacuum screen printing machine base is provided with a vacuum adsorption table, and baffles are provided on both sides of the vacuum adsorption table. The outer side of the baffle is provided with symmetrically arranged limit grooves, and the inner part of the limit groove is slidably connected to the limit rod. The top of the baffle is fixedly connected to a connecting plate, the outer side of the connecting plate is provided with a first fixing hole, the outer side of the connecting plate is slidably connected to an outer shell, and the outer side of the outer shell is provided with a second fixing hole, and the inner parts of the first fixing hole and the second fixing hole are spirally connected to threaded rods.

[0007] Preferably, a spring is fixedly connected to the inside of the shell, the bottom end of the spring is fixedly connected to a push plate, the bottom end of the push plate is fixedly connected to a rubber layer, and the bottom end of the rubber layer is provided with a plastic plate located inside the shell.

[0008] Preferably, there are four springs, and the springs are symmetrically arranged between the housing and the push plate.

[0009] Preferably, the limiting grooves and limiting rods form a group, and there are four groups of limiting grooves and limiting rods in total, which are symmetrically arranged below the shell.

[0010] Preferably, the first fixing holes and the second fixing holes form a group, there are twelve groups of the first fixing holes and the second fixing holes in total, and the shapes and sizes of the first fixing holes and the second fixing holes match.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. In the utility model, the hollow adsorption platform, baffle, limit groove, limit rod, connecting plate, spring, push plate and rubber layer and other components are provided. First, the limit rod is pulled out of the limit groove, and then the plastic plates are placed in the shell in sequence. As the plastic plates are placed, the plastic plates will squeeze the rubber layer and the push plate, and the spring will be compressed by the push plate. After a certain number of plastic plates are placed, the limit rod is reinserted into the limit groove to prevent the plastic plates from popping out. After the plastic plates are installed, the threaded rod is rotated to remove them from the first fixing hole and the second fixing hole, and then the distance between the baffle and the shell is adjusted according to the current thickness of the plastic plates. After adjustment, the threaded rod is screwed into the overlapping first fixing hole and the second fixing hole again, and then the baffle is directly engaged on both sides of the vacuum adsorption platform from above, and the baffle and the shell are aligned with the vacuum adsorption platform, and then pulled out. When the limit rod comes out, the spring, push plate and rubber layer will push the plastic plate and the vacuum adsorption table to fit together. At this time, the plastic plate is exactly in the center position, and there is no need to adjust the position of the plastic plate at all. Then pull the shell directly towards yourself. When the baffle moves to only half of the contact with the vacuum adsorption table, press the plastic plate with your hand to prevent it from popping out, and then continue to pull the shell until the baffle and the vacuum adsorption table are completely separated. Repeat the above actions directly to align the shell and the baffle with the vacuum adsorption table, and then release the hand holding the plastic plate. The new plastic plate can be placed. When it is necessary to pause, just reinsert the limit rod into the limit slot, thereby solving the problem that the existing vacuum screen printing machine generally needs to manually place the plastic plate to be printed. In order to ensure printing quality, the plastic plate needs to be placed in the center position, which requires manual calibration, which is inefficient and prone to errors.

[0013] 2. In the present invention, by providing the first fixing hole, the second fixing hole and the threaded rod and other components, corresponding adjustments can be made according to the plastic plates of different thicknesses, so that the distance between the shell and the vacuum adsorption table is the same as the thickness of the plastic plate, thereby ensuring smooth removal of the shell.

The top of the baffle 3 is fixedly connected to a connecting plate 6, and a first fixing hole 7 is provided on the outer side of the connecting plate 6. The outer side of the connecting plate 6 is slidably connected to an outer shell 8, and a second fixing hole 9 is provided on the outer side of the outer shell 8. The first fixing hole 7 and the second fixing hole 9 are spirally connected to a threaded rod 10.

[0025] The inside of the shell 8 is fixedly connected to a spring 11, and the bottom end of the spring 11 is fixedly connected to a push plate 12, and the bottom end of the push plate 12 is fixedly connected to a rubber layer 13. The bottom end of the rubber layer 13 is provided with a plastic plate 14 located on the inside of the shell 8. There are four springs 11, and the springs 11 are symmetrically arranged between the shell 8 and the push plate 12. The multiple springs 11 set up can push the push plate 12 more smoothly; the limit slot 4 and the limit rod 5 are a group, and there are four groups of limit slots 4 and limit rods 5, and they are symmetrically arranged at the bottom of the shell 8. The four groups of limit rods 5 set up can better engage the plastic plate 14 and maintain the balance of the plastic plate 14 when being squeezed by the spring 11; the first fixing hole 7 and the second fixing hole 9 are a group, and there are twelve groups of first fixing holes 7 and second fixing holes 9. The shapes and sizes of the first fixing holes 7 and the second fixing holes 9 match, which is convenient for adjusting the direct spacing between the shell 8 and the connecting plate 6.

[0026] Working process: When a vacuum screen printing machine is needed, first pull the limit rod 5 to pull it out of the limit groove 4, and then put the plastic plate 14 into the shell 8 in turn. As the plastic plate 14 is put in, the plastic plate 14 will squeeze the rubber layer 13 and the push plate 12, and the spring 11 will be compressed by the push plate 12.
