Technical Field
[0001] This utility model relates to the field of bag making machine punching technology, specifically to an automatic correction punching device for bag making machines. Background Technology
[0002] A bag-making machine is a highly automated packaging machine mainly used to produce plastic bags, paper bags, and composite bags of various specifications. It can process packaging bags of various sizes and thicknesses made of plastic or other materials, with plastic packaging bags being the primary product. Bag-making machines can be divided into fully automatic and semi-automatic types. Fully automatic bag-making machines achieve fully automated operation, requiring only 1-2 operators, and allow adjustment of production speed and product size. These machines are typically equipped with touchscreen operation, stepper length control, photoelectric tracking, automatic counting, and automatic punching devices.
[0003] Chinese patent discloses a punching device for a bag making machine (authorization announcement number CN 210759512 U). This patented technology allows for convenient adjustment of the punching spacing and number of punches as needed by setting up a first slide, a second slide, a connecting seat, a punching column, and fastening bolts. The punching column and connecting seat can be easily disassembled, and the connecting seat can also be easily removed from the sliding seat, making the maintenance and repair of the device very convenient. However, this device requires workers to place bags under the punching column one by one, which is a large workload.
