Abstract

The invention discloses a plastic bag punching device which comprises a rotating shaft, and the rotating shaft is wrapped with a semi-annular upper needle shell and a semi-annular lower needle shell.Puncture needles are formed on the upper needle shell and the lower needle shell. Annular grooves matched with the upper needle shell and the lower needle shell are formed in the rotating shaft. Fixing sections extend out of the two sides of the upper needle shell and the two sides of the lower needle shell and are fixed to the rotating shaft through bolts. The upper needle shell and the lower needle shell can be replaced according to needs, so that a whole needle roller does not need to be disassembled and replaced, and the time for replacing needle rollers of different specifications is shortened.

Description

technical field [0001] The invention belongs to the field of machinery, and in particular relates to a plastic bag piercing device. Background technique [0002] Existing plastic bags are usually used for packaging, and when used for packaging seeds, etc., holes are required on the bag, so holes need to be pricked on the bag. But different bags require different hole specifications and spacing. Therefore need often change needle roller, operation is complicated. Contents of the invention [0003] In order to solve the above problems, the invention discloses a plastic bag piercing device. The upper needle case and the lower needle case of the present invention can be replaced as required, so that the entire needle roller need not be disassembled and replaced, and the time for replacing needle rollers of different specifications is accelerated. [0004] To achieve the above object, the technical solution of the present invention is: [0005] A plastic bag piercing device...
