Description

Technical Field

[0001] This utility model relates to the field of paper bag processing technology, and in particular to a punching machine for paper bag processing. Background Technology

[0002] Paper bags are made from trees, a renewable resource, and are inherently biodegradable and recyclable. Paper bags play an important role in people's daily lives. There are many varieties of paper bags, with diverse paper materials and styles. During the production of paper bags, a punching machine is used to punch holes to assemble parts.

[0003] A search revealed a paper bag punching machine under publication number CN218804340U, comprising a worktable, a support frame fixedly connected to the worktable, an mounting bracket fixedly above the support frame, a first rotating rod below the mounting bracket, a first gear fixedly connected to the lower end of the first rotating rod, a second gear fixedly located to the right of the first gear, a second rotating rod fixedly connected to the upper end of the second gear, and telescopic devices respectively located on the lower end faces of the first and second gears. The top end of a threaded rod is fixedly fixed to the lower end faces of the first and second gears, and the lower end of the threaded rod is threadedly connected to a threaded cylinder. A mounting plate is fixedly connected to the lower end of the telescopic device, a rotating shaft is rotatably connected below the mounting plate, a punch is fixedly located at the bottom end of the rotating shaft, a sleeve is sleeved on the outside of the rotating shaft, the bottom of the sleeve is rotatably connected to the punch, and a limit rod is fixedly sleeved on the sleeve. This design reduces labor costs, allows for more accurate punching of paper, and improves the product qualification rate.

[0004] Although the above solution prevents paper from wrinkling during the punching process and ensures the pass rate of paper bags through the design of the puncher and limiting device, it cannot easily adjust the punching position and has low applicability. Therefore, we propose a punching machine for paper bag processing. Utility Model Content
