Abstract

The invention provides a plastic film punching device, and belongs to the mechanical technical field, which can solve the problem that punching needles are difficult to change in the conventional plastic film punching devices. The plastic film punching device includes a support and a roller; one end of the roller is axially fixed on the support and is connected to a motor, and a circular groove is formed in the other end of the roller; a cylindrical electric magnet is inserted into and fixed in the circular groove; a seal plate for sealing an opening of the circular groove is fixed on the roller; a connection portion is arranged on the seal plate; the connection portion is axially fixed on the support; a storage battery for supplying power to the electric magnet and a switch for controlling communication or disconnection between the electric magnet and the storage battery are fixed on the connection portion; a plurality of connection holes communicating with the circular groove are formed in an outer wall of the roller; punching needles made of a stainless steel material are inserted into the connection holes; and one ends of the punching needles are pressed against an outer side wall of the electric magnet, and the other ends of the punching needles are solid cone-shaped and stretch out of the connection holes. The plastic film punching device can facilitate changing punching needles.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to a punching device, in particular to a plastic film punching device. Background technique [0002] When plastic film is used in some fields, such as packaging, it is often necessary to punch holes, otherwise there will be problems such as large packaging volume. The existing plastic film punching generally uses manual punching, but the speed of manual punching is slow, uneven, and the size of the punched holes is different, it is easy to be biased, the size of the punched holes is not easy to control, and the punching efficiency is low. Low. [0003] For this situation, people have been aware of this deficiency and have improved it, such as a kind of plastic film punching device disclosed in Chinese patent documents [ Application Number: 201520402183.X ; Authorization announcement number: CN 204748776 U ] , including a drum and a bracket, the drum is provided with ...
