Description

Continuous plastic paper cup plastic packaging machine Technical Field The invention belongs to the technical field of packaging, and particularly relates to a continuous plastic paper cup plastic packaging machine. Background In the paper cup production and distribution process, in order to facilitate storage, transportation and keep the product clean and sanitary, a plurality of paper cups are usually packaged together into an independent sales unit. The package can not only effectively prevent paper cups from scattering and deforming in the process of carrying, but also prevent the drinking edge parts of the paper cups from being polluted by dust, moisture and the like, and is an important link for guaranteeing the product quality and improving the commodity display image. At present, a heat shrinkage film is commonly adopted in the market to carry out plastic package packaging on paper cups. The basic packaging material used in common packaging machines is a preformed tubular (or sleeve-like) plastic film. When the film cutting and heat sealing mechanism of the packaging machine acts, a film sleeve with a fixed size is sleeved into a group of paper cups which are orderly arranged from top to bottom, and the cylindrical film is structurally designed so that the packaging can be completed only by performing a heat sealing process on the bottom. However, this packaging approach, which relies on a "telescoping" action, implies an inherent operational difficulty. Because the packaging film is of a cylindrical structure with a preset caliber, the opening size of the packaging film is fixed, and the whole paper cup group to be packaged is approximately cone-shaped with a big upper part and a small lower part. In the film coating process, operators must precisely align and pass through the cylindrical film opening, and the operation fault tolerance is low, so that the packaging efficiency is poor. Disclosure of Invention The embodiment of the invention provides a continuous plastic paper cup plastic packaging machine, which aims to solve the technical problems of low fault tolerance and poor packaging efficiency caused by a cylindrical packaging film.
