[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Reference Figure 1-Figure 6 The paper notebook paper punching machine provided in this embodiment includes a processing table 1, a mounting frame 2 is fixedly installed on the processing table 1, and a mounting plate 4 that moves up and down above the processing table 1 is arranged on the mounting frame 2 through a cylinder 3, and a plurality of mounting openings 41 arranged at equal intervals along the length direction of the mounting plate 4 are opened on the mounting plate 4, and a tool assembly 5 for punching is detachably installed on the mounting plate 4 through the mounting opening 41.

[0023] In the utility model, when punching paper of a paper notebook, the number of holes to be punched and the spacing of the holes to be punched are determined according to the size of the paper, and then a corresponding number of tool assemblies 5 are inserted into the mounting openings 41 of the mounting plate 4, and the tool assemblies 5 are inserted into the mounting openings 41 of the corresponding spacing according to the required punching spacing, so that the punching machine can adapt to the punching needs of papers of different sizes, and then the paper to be punched is placed on the processing table 1, the cylinder 3 on the mounting frame 2 is started and the mounting plate 4 is driven to descend by the cylinder 3, thereby driving the tool assembly 5 on the mounting plate 4 to contact the paper on the processing table 1, and as the cylinder 3 is driven, the tool assembly 5 performs punching work on the paper.

[0024] Specifically, refer to Figure 1 , Figure 3 and Figure 4The tool assembly 5 includes a socket 51 matched with the mounting opening 41, a punching knife 53 is arranged at the bottom of the socket 51 through a limiting plate 52, the size of the limiting plate 52 is larger than the size of the mounting opening 41, and mounting grooves 54 are provided on the left and right sides of the socket 51, and a limiting block 55 is arranged on the mounting groove 54 through a spring 56. When installing the tool assembly 5, align the socket 51 with the mounting opening 41, and then insert it into the mounting opening 41 from bottom to top. When the socket 51 is inserted, the limiting block 55 is squeezed and the spring 56 is compressed, and the limiting block 55 shrinks in the mounting groove 54. As the limiting plate 52 abuts against the lower side of the mounting plate 4, the upper end of the socket 51 passes through the mounting opening 41, and then the limiting block 55 pops up under the action of the spring 56 and abuts against the upper side of the mounting plate 4, so that the limiting plate 52 and the limiting block 55 fix the socket 51, and then the punching knife 53 is fixed below the mounting plate 4;

[0025] It should be noted that the punching knife 53 is limited by a limiting plate 52 which is larger than the size of the mounting opening 41. When the punching knife 53 punches holes by stamping, the limiting plate 52 abuts against the lower side of the mounting plate 4, thereby avoiding the deviation of the punching knife 53 and ensuring the accuracy of the punching.

[0026] The upper side of the socket 51 is provided with a slide groove 57 connected to the mounting groove 54, and a pull plate 58 is fixedly connected to the limit block 55, which passes through the slide groove 57 and extends to the top of the socket 51. The limit block 55 is pulled by the pull plate 58. When the tool assembly 5 is disassembled, the operator presses the pull plate 58 with his fingers and moves the pull plate 58 toward the middle, so that the limit block 55 is retracted into the mounting groove 54, and then the socket 51 is pulled out downward to realize the disassembly of the tool assembly 5, which is simple and convenient.

[0027] Specifically, refer to Figure 1 and Figure 2 Both ends of the mounting plate 4 are provided with connecting sleeves 42 that match the piston rod of the cylinder 3, and holes for screw connection are provided on the connecting sleeves 42. The piston rod of the cylinder 3 is connected to the connecting sleeves 42 by screws in the holes, which can facilitate the installation and disassembly between the piston rod of the cylinder 3 and the mounting plate 4, thereby facilitating the disassembly of the mounting plate 4 for maintenance.

[0028] Specifically, refer to Figure 1 and Figure 5 The processing table 1 is provided with a baffle plate 6 perpendicular to the mounting plate 4 through a fixing plate 61, and a plurality of mounting openings 41 on the mounting plate 4 are located on the same side of the baffle plate 6. When punching a hole in a paper, one end of the paper is pressed against the baffle plate 6. Since the baffle plate 6 is perpendicular to the mounting plate 4, after the paper is pressed against the baffle plate 6, it can be ensured that the hole opened on the paper by the tool assembly 5 on the mounting plate 4 will not be tilted, thereby improving the accuracy of the punching machine.

[0029] Specifically, refer to Figure 1 and Figure 6 A tool box 7 for storing spare tool assemblies 5 is provided on the mounting frame 2 at one side of the cylinder 3. The tool box 7 is used to store spare tool assemblies 5. When the size of paper is large and multiple holes need to be punched, the tool assemblies 5 can be taken from the tool box 7 and quickly plugged into the mounting plate 4, which is convenient for adjusting the number of tool assemblies 5, so that the punching machine can quickly adapt to the punching needs of papers of different sizes, thereby improving the punching efficiency of the punching machine.
