[0002] During the production process of traditional paper bag machines, the punching link is a crucial step, used to create holes through which fingers or other tools can pass to facilitate the use of the paper bags. It directly affects the finished product quality and usability of the paper bags. However, the punching devices of traditional paper bag machines usually rely on fixed punching mechanisms and position settings, and cannot flexibly and quickly adjust the punching positions. In actual production, due to the diverse specifications of paper bags and different requirements for punching positions, traditional punching devices often struggle to meet such diverse needs. Therefore, it is necessary to solve the above technical problems. Summary of the Invention

[0029] Please refer to Figures 1 to 3 together. Now, a punching device for a paper bag machine provided by an embodiment of the present application will be described. The punching device for the paper bag machine includes a wallboard 101, a conveying assembly, a moving assembly, and a punching assembly. Among them:

[0030] The conveying assembly includes a support plate 102 that is spaced apart and connected to the wallboard 101, and a push rod 103 that is movably arranged within the space between the support plates 102 and can move linearly along the channel formed by the space between the support plates. The moving assembly includes a punching seat 104 and an adjusting mechanism that is connected to the punching seat 104 and is used to drive the punching seat 104 to move within a plane parallel to the support plate 102. The punching seat 104 forms a spaced-apart top plate 105 and a bottom plate 106 in a direction perpendicular to the support plate 102. The upper end surface of the support plate 102 is flush with the upper end surface of the bottom plate 106. The punching assembly includes a cylinder 107 connected to the top plate 105, a punch 108 connected to the output end of the cylinder 107, and a die 109 connected to the bottom plate 106 and through which the punch 108 passes.

According to the above structure provided in this embodiment, the punching seat 104 can move relative to the second guide rod 114 through the moving seat 115 and move relative to the first guide rod 112 through the moving guide plate 113, so as to flexibly move in a plane parallel to the support plate 102, which is beneficial to further improving the punching flexibility of the punching device of the paper bag machine in this embodiment.
