The two pressing rollers are respectively located on both sides below the punching head. The two pressing rollers are connected to the mounting plate through a connecting mechanism. A hydraulic pump is arranged on the connecting frame, and the telescopic end of the hydraulic pump is connected to the mounting plate to push the pressing rollers and the punching head to move downward to flatten and fix the sheet material during punching.

[0005] Further, the moving module is composed of two first electric sliders, two second electric sliders and a third electric slider. The two first electric sliders are arranged on the workbench at intervals in the front-back direction, and a second electric slider is vertically arranged on the sliding end of the first electric slider. The third electric slider is located between the first electric sliders, and both ends of the third electric slider are respectively connected to the moving ends of the second electric sliders. The sliding end of the third electric slider is connected to a connecting frame.

[0006] Further, the connecting mechanism includes two vertical plates arranged at intervals left and right at the bottom end of the connecting frame. Two connecting rods are arranged between the two vertical plates. Limiting cylinders are fixedly sleeved in the middle of the two connecting rods. Two connecting blocks are slidably arranged on each of the two connecting rods, and the connecting blocks are respectively hinged to the mounting plate through movable rods. The bottom ends of the connecting blocks bulge downward, and two relatively front and rear connecting blocks form a group. The front and rear ends of the pressing roller are respectively rotatably connected to the connecting blocks of the same group through bearings. The connecting blocks and the vertical plates are connected through elastic members.

[0007] Further, limiting grooves are formed in both of the two vertical plates. Sliders are arranged at the left and right ends of the mounting plate and are respectively slidably connected to the adjacent limiting grooves through the sliders.

[0008] Further, the elastic member is a spring. The spring is fixedly sleeved on the connecting rod, and one end of the spring is fixed to the connecting block, and the other end is fixed to the vertical plate.

[0009] Compared with the prior art, the technical solution of this application has the following beneficial effects: The air cylinder drives the mounting plate to displace downward. The mounting plate simultaneously drives the punching head and the pressing roller to displace downward, so that the pressing roller first contacts the paper. At this time, the pressing roller continues to be under pressure and rolls to both sides through the connecting mechanism, fixing and flattening the paper, so as to facilitate the punching head to punch the paper.

Detailed Embodiment

[0014] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model.

[0015] Please refer to Figures 1 - 3, A punching machine for printing plates in this embodiment includes a workbench 1. A moving module 2 is arranged on the workbench 1. A connecting frame 3 is arranged on the moving end of the moving module 2. An installation plate 6 is arranged below the connecting frame 3. A punching head 14 and two pressing rollers 13 are respectively arranged on the installation plate 6. The two pressing rollers 13 are respectively located on both sides below the punching head 14. The two pressing rollers 13 are connected to the installation plate 6 through a connecting mechanism. A hydraulic pump 4 is arranged on the connecting frame 3, and the telescopic end of the hydraulic pump 4 is connected to the installation plate 6 to push the pressing rollers 13 and the punching head 14 to move downward to flatten and fix the sheet material during punching.

[0016] In this embodiment, the moving module 2 drives the connecting frame 3 and the structures on the connecting frame 3 to move back and forth, up and down, left and right to adjust the punching position and distance. After the punching position and distance are adjusted, the air cylinder drives the installation plate 6 to move downward, so that the pressing rollers 13 first contact the paper and press the paper downward and fix it through pressure. Then the installation plate 6 continues to move downward so that the two pressing rollers roll away from each other. At this time, the punching head 14 contacts the paper and punches the paper.

[0017] Preferably, as another embodiment of the present invention, the moving module 2 is composed of two first electric sliding tables, two second electric sliding tables and a third electric sliding table. The two first electric sliding tables are arranged on the workbench 1 at intervals in the front-back direction. A second electric sliding table is vertically arranged on the sliding end of the first electric sliding table. The third electric sliding table is located between the first electric sliding tables, and both ends of the third electric sliding table are respectively connected to the moving ends of the second electric sliding tables. The sliding end of the third electric sliding table is connected to a connecting frame 3.

[0018] In this embodiment, the first sliding table is used to adjust the punching position of the punching head 14 in the front-back direction, the second sliding table is used to adjust the height between the punching head 14 and the punching paper, and the third sliding table is used to adjust the punching position of the punching head 14 in the left-right direction.

[0019] Preferably, as another embodiment of the present invention, the connecting mechanism includes two vertical plates 5 arranged at intervals left and right at the bottom end of the connecting frame 3. Two connecting rods 8 are arranged between the two vertical plates 5. Limiting cylinders 10 are sleeved and fixed in the middle of the two connecting rods 8. Two connecting blocks 9 are slidably arranged on the two connecting rods 8, and the connecting blocks 9 are respectively hinged to the installation plate 6 through movable rods 12. The bottom ends of the connecting blocks 9 protrude downward, and two front-back opposite connecting blocks 9 are in a group. Both the front and rear ends of the pressing roller 13 are respectively rotatably connected to the connecting blocks 9 of the same group through bearings. The connecting blocks 9 are connected to the vertical plates 5 through elastic members.

[0020] In this embodiment, the second sliding table is first used to control the pressing roller to contact and press the paper, and then the hydraulic pump 4 is started to drive the mounting plate 6 to move downward, so that the two movable rods 12 on the same side are opened, and the connecting blocks 9 are driven to move away from each other. The connecting blocks 9 drive the pressing rollers 13 to move, so as to roll and flatten the paper to be punched, ensuring the punching quality of the punching head 14.

[0021] Preferably, as another embodiment of the present invention, limiting grooves 7 are formed on both vertical plates 5, and sliding blocks 15 are arranged at the left and right ends of the mounting plate 6, and are respectively slidably connected to the adjacent limiting grooves 7 through the sliding blocks 15.

[0022] In this embodiment, the mounting plate 6 is limited by the design of the sliding blocks 15 and the limiting grooves 7, so that the mounting plate 6 moves linearly up and down to ensure the accuracy of the punching of the punching head 14.

[0023] Preferably, as another embodiment of the present invention, the elastic member is a spring 11. The spring 11 is sleeved and fixed on the connecting rod 8, and one end of the spring 11 is fixed to the connecting block 9, and the other end is fixed to the vertical plate 5.

[0024] In this embodiment, the spring 11 is compressed when the connecting blocks 9 move away from each other, and rebounds when the pressure is lost, so as to reduce the buffer during the movement of the connecting blocks 9.

[0025] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
