[0022] The intermittent adjustment component 6 includes a fixed plate 61, which is installed on the punching frame 3. A cylinder 62 is provided in the middle of the top of the fixed plate 61, and a telescopic shaft 63 is provided on the top of the cylinder 62. The top of the telescopic shaft 63 is connected to the top of the upper punching component 4. The top of the upper punching component 4 is lifted up by the cylinder 62, so that the upper punching component 4 is away from the upper surface of the paper, and the punching can be stopped.

[0023] In this embodiment, the paper output rack 1 is provided with an output shaft 11 and a first tensioning shaft 12, so that the paper is kept taut during transmission.

[0024] Specifically, the paper winding frame 2 is provided with a winding shaft 21 and a second tensioning shaft 22 to ensure that the paper is taut during transmission. One end of the winding shaft 21 is driven to rotate by a servo motor.

[0025] Furthermore, a spring 64 is connected between the top of the upper punching assembly 4 and the fixing plate 61. The spring 64 can pull the upper punching assembly 4 back to its original position through elastic force after the cylinder 62 stops lifting the upper punching assembly 4.

[0026] Furthermore, the upper punching assembly 4 includes an upper horizontal plate 41, both ends of which are supported by the intermittent adjustment assembly 6, upper vertical plates 42 are provided at the bottom of both ends of the upper horizontal plate 41, and an upper shaft 43 is provided between the upper vertical plates 42, both ends of the upper shaft 43 are rotatably connected with the upper vertical plates 42 through bearings, and the upper shaft 43 is driven to rotate by a servo motor, and a plurality of punching needles 44 are provided on the outer wall of the upper shaft 43, and the upper shaft 43 is driven to rotate by the servo motor, thereby achieving synchronization with the paper, and when the upper shaft 43 passes through the paper, micropores are generated on the surface of the paper by the punching needles 44 to realize the punching operation of the paper.

[0027] Furthermore, the punching needles 44 are divided into several groups, and the spacing between each group is equal. Each group of punching needles 44 is installed on the outer wall of the upper shaft 43 in a ring shape with equal spacing, ensuring that the punched holes are evenly arranged.

[0028] Furthermore, the lower punching assembly 5 includes a lower horizontal plate 51, which is installed on the outer wall of the punching frame 3. Lower vertical plates 52 are provided at both ends of the top of the lower horizontal plate 51, and a lower shaft 53 is provided between the tops of the lower vertical plates 52. Both ends of the lower shaft 53 are rotatably connected to the lower vertical plates 52 through bearings. The lower shaft 53 is driven to rotate by a servo motor. A plurality of annular grooves 531 are provided on the outer surface of the lower shaft 53. The annular grooves 531 are arranged at equal intervals.

[0030] When the intermittent punching mechanism for paper bag processing of the utility model is used, the device is first assembled, and the paper to be punched is wound on the output shaft 11 of the paper output rack 1, and then the paper is pulled to pass between the upper punching assembly 4 and the lower punching assembly 5, and finally wound on the reeling shaft 21 of the paper reeling rack 2, and the reeling shaft 21, the upper shaft 43, and the lower shaft 53 are driven by the servo motor to rotate synchronously, so that when the paper passes between the upper punching assembly 4 and the lower punching assembly 5, its movement speed is the same as that of the upper shaft 43 and the lower shaft 53. The linear speed of the shaft 53 is consistent, and micropores are generated on the surface of the paper through the punching needle 44 to realize the punching operation of the paper. The punched paper is rolled up on the winding shaft 21. When the sealed end of the paper passes between the upper punching component 4 and the lower punching component 5, the cylinder 62 lifts the top of the upper punching component 4 to make the upper punching component 4 away from the upper surface of the paper, and the punching can be stopped. After the sealing end of the paper passes, the telescopic shaft 63 of the cylinder 62 is retracted to realize the return of the upper punching component 4 and continue to realize the punching operation.
