Paper-plastic straw and manufacturing method thereof

Abstract

The invention discloses a paper-plastic straw and a manufacturing method thereof. The manufacturing method comprises the following steps that firstly, a paper-plastic finished product manufacturing method is adopted to manufacture a base plate, the base plate is provided with at least one bent arc part, the base plate is also provided with plane parts at the positions without the bent arc parts, then the base plate is subjected to primary punching, two end parts of each bent arc part in the base plate are subjected to transverse punching according to the length required for manufacturing the paper-plastic straw in expectation, so that a short base plate with two empty ends of the bent arc part is formed, glue is further sprayed on each plane part on the inner side surface of the short baseplate, then the two short base plates subjected to glue spraying are attached in an inner surface opposite state, the bent arc parts originally belonging to the two short base plates are combined into a round pipe, the plane parts are correspondingly glued, a precursor finished product of the paper-plastic straw is formed, finally, secondary punching is carried out on the outer side surface of the precursor finished product at the position a tiny distance away from the bent arc parts, tiny joint sheets and bent arc parts are left behind, and two ends are each provided with a round opening toform the paper-plastic straw.

Description

【Technical field】 [0001] The invention relates to a paper-plastic straw and a manufacturing method thereof, in particular to a paper-plastic straw that is recyclable, naturally decomposable, and fully meets environmental protection requirements and a manufacturing method thereof. 【Background technique】 [0002] There are many hand-cranked beverage shops on the street. The fact that every hand-cranked beverage shop has people queuing up to buy drinks almost from morning till night shows the prosperity of the hand-cranked beverage shop industry. In hand-cranked beverage shops, the customer who purchases specifies which beverage he wants on the spot and completes the payment, and then the clerk quickly uses a beverage cup to fill the required materials to directly brew the beverage ordered by the customer, and then uses the stability of the lid to Cover the mouth of the cup, or use a sealing machine to seal the mouth of the cup, so that the production of a hand-shake drink is q...

AI Technical Summary

Problems solved by technology

The reason is that the so-called "straw" must be formed as a long tubular body with openings at both ends, which can be inserted into the beverage and drink the beverage surrounded by the other open end from one open end. Therefore, plastic straws are the easiest to drink. The forming method is drawing, but it is impossible to directly implement drawing in the manufacturing technology of paper-plastic products, so no paper-plastic straws have appeared so far.
