DETAILED DESCRIPTION

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Example 1

[0034] like Figures 1-8 As shown, the pressing device of the printing machine proposed in this invention includes a base 1, a cylinder 2 fixedly connected to the outside of the base 1, a fixing rod 3 provided at the output end of the cylinder 2, and a mounting block 4 fixedly connected to the side of the fixing rod 3 away from the cylinder 2.

[0035] Mounting block 4 is symmetrically fixedly connected to fixing blocks 9 on the outside. Mounting block 4 is provided with a sliding mechanism. The sliding mechanism includes a sliding support block 11 provided on the outside of mounting block 4. A pressing platform 12 is provided on the side of sliding support block 11 away from fixing block 9. Sliding support block 11 is slidably connected to mounting block 4. An inclined block 13 is fixedly connected on the side of sliding support block 11 close to fixing block 9. A buffer shaft 10 is slidably connected inside fixing block 9. A sliding plate 16 is fixedly connected to the outside of buffer shaft 10. A second spring 15 is fixedly connected to the outside of sliding plate 16. The side of second spring 15 away from sliding plate 16 is fixedly connected to mounting block 4.

[0036] A support frame 6 is fixedly connected to the outside of the base 1. A conveyor belt 5 is provided on the side of the support frame 6 away from the base 1. The mounting block 4 is symmetrically provided with first sliding grooves 8. A sliding block 14 is fixedly connected to the outside of the sliding support block 11. The sliding block 14 is slidably connected to the first sliding groove 8.

[0037] The sliding block 14 is externally fixedly connected to a first spring 7. The side of the first spring 7 away from the sliding block 14 is fixedly connected to the mounting block 4. The fixed block 9 has a fourth sliding groove 23 inside. The sliding plate 16 is slidably connected to the fourth sliding groove 23.

[0038] The working principle of the pressing device of the printing machine proposed in this invention is as follows: the product to be printed is placed on the conveyor belt 5. When the product passes under the mounting block 4, the movement of the conveyor belt 5 is stopped, the cylinder 2 is started, the cylinder 2 drives the fixed rod 3 to move downward, and the movement of the fixed rod 3 drives the mounting block 4 to move downward as a whole. During the downward movement, when the buffer shaft 10 contacts the conveyor belt 5, it continues to move downward. The buffer shaft 10 slides upward under the force of the conveyor belt 5. The buffer shaft 10 drives the sliding plate 16 to slide inside the fourth slide groove 23. During the sliding process, the sliding plate 16 will squeeze the second spring 15.

[0039] When the buffer shaft 10 moves upward and contacts the inclined block 13, the buffer shaft 10 continues to move upward. While moving, the buffer shaft 10 will squeeze the inclined block 13. Since the inclined surface of the inclined block 13 is in contact with the inclined surface of the buffer shaft 10, the inclined block 13 will move away from the fixed block 9 after being squeezed. The movement of the inclined block 13 will drive the sliding support block 11 to move together. The sliding block 14 installed on the sliding support block 11 will also move in the same way. The sliding block 14 moves inside the first slide groove 8. During the process of the sliding block 14 moving away from the fixed block 9, it will squeeze the first spring 7. During this process, the distance between the two sliding support blocks 11 will get closer and closer.

[0040] When the buffer shaft 10 stops squeezing and pushing the inclined block 13, the two pressing tables 12 will come into contact to complete the pressing of the product. After the pressing tables 12 have come into contact, that is, when the buffer shaft 10 stops squeezing and pushing the inclined block 13, the buffer shaft 10 will continue to move upward for a period of time under the action of the mounting block 4 and the conveyor belt 5, to provide a buffer distance for pressing, and to avoid irregular printing caused by the pressing device being unable to change the downward pressing distance. Since the sliding support block 11 moves along the first sliding groove 8 on the mounting block 4 during the movement process, the movement of the pressing table 12 is also kept horizontal, and the ink will not float on the surface of the printed material, thus completing the pressing process efficiently with guaranteed quality and quantity.

[0041] Example 2

[0042] like Figures 1-8 As shown, a quick-fixing mechanism is provided on the outside of the sliding support block 11. The quick-fixing mechanism includes a fifth slide groove 24 provided on the outside of the sliding support block 11. A support block 21 is fixedly connected to the outside of the pressing table 12. The support block 21 and the fifth slide groove 24 are slidably connected.

[0043] The support block 21 has a second sliding groove 19 symmetrically opened on the outside. The sliding support block 11 is rotatably connected to a bidirectional threaded rod 17. The bidirectional threaded rod 17 is symmetrically threaded to a fixing plate 18. The fixing plate 18 is slidably connected to the second sliding groove 19.

[0044] The sliding support block 11 has symmetrically opened control holes 25 on its exterior. The bidirectional threaded rod 17 is rotatably connected to the control holes 25. The fixed plate 18 has threaded holes 20 on its exterior. The bidirectional threaded rod 17 is threadedly connected to the threaded holes 20. The sliding support block 11 has symmetrically opened third slide grooves 22 inside. The fixed plate 18 is slidably connected to the third slide grooves 22.

[0045] The working principle of the pressing device of the printing machine is that when the pressing table 12 needs to be replaced or overhauled, the bidirectional threaded rod 17 is rotated to make the two fixed plates 18 move outward, the fixed plates 18 slide in the third sliding groove 22, when the bidirectional threaded rod 17 cannot continue to rotate, the fixed plates 18 no longer limit the support blocks 21 through the second sliding groove 19, and the support blocks 21 can easily slide in the fifth sliding groove 24, at this time, the pressing table 12 is removed, and the pressing table 12 is replaced or overhauled;

[0046] When the pressing table 12 needs to be installed in place to work, the support blocks 21 on the pressing table 12 are inserted into the fifth sliding groove 24 on the sliding support block 11, the bidirectional threaded rod 17 is reversed, the bidirectional threaded rod 17 reverses to drive the two fixed plates 18 to slide to the inside of the sliding support block 11, the fixed plates 18 slide into the second sliding groove 19, at this time, the fixed plates 18 have completed the limitation of the support blocks 21, that is, the pressing table 12 has been fixedly installed on the sliding support block 11, when the bidirectional threaded rod 17 cannot continue to rotate, the fixed plates 18 completely slide into the second sliding groove 19 to realize the strong fixation of the support blocks 21, that is, the pressing table 12, the whole process is simple and fast, and the replacement and overhaul efficiency of the pressing table 12 is improved.

[0047] Although the embodiments of the present application have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the present application, and the scope of the present application is limited by the appended claims and their equivalents.
