Description

New Paper Cup Paper Bowl Forming Machine

technical field

The utility model belongs to the technical field of paper cup forming and processing, in particular to a novel paper cup and paper bowl forming machine.

Background technique

Paper cup (bowl) is a kind of paper container made by mechanical processing and bonding of base paper (white cardboard) made of chemical wood pulp. Mainly divided into single-sided PE coating and double-sided PE coating. The size of the paper cup measures the size of the paper cup in ounces (OZ). From the perspective of shape and paper quality, it has gone through the development process of conical paper cups → waxed paper cups → straight wall double-layer cups → polyethylene coated paper cups. At present, polyethylene coated paper cups are mainly used, which can carry cold and hot drinks. .

At present, the production of polyethylene-coated paper cups mainly includes low, medium and high-speed forming machines, which are special light industrial equipment for the production of disposable paper cups (bowls). Its main production process: take cup body paper → paper feeding → cup body forming → cup body feeding → flipping → upper cup body; cup bottom paper feeding → cutting → bottom feeding → preheating → heating → rolling bottom → rolling bottom forming →Lower the cup→coat with silicone oil→first roll mouth→second roll mouth→(paper bowl water line)→cup out and other processes. It is mainly composed of paper feeding system, cup bottom forming system, cup mouth forming system, transmission system, electrical control system and so on.

Domestic paper cup forming machines generally use three indexing turntables. Bottom rolling and roll opening are completed by the main indexing turntable and the lifting platform below. This structure requires that the up and down movement of the lifting platform must be higher than the height of the paper cup. The rolling bottom and mouth rolling process in the area increases the load of the working cam, and the stability of the machine is poor, which seriously restricts the improvement of the speed, which can only reach about 40 pieces/minute, but the paper quality suitable for the domestic market has already been used. rare. There are also two indexing turntables, and the bottom rolling and rolling mouth are completed on their own forming components. The working stroke has nothing to do with the height of the paper cup, which can be greatly shortened and the mechanism load is greatly improved. However, due to the stability and reliability of the system integration Poor and other problems, the average production speed can be maintained at about 80 pieces/minute, and the market share is the highest.

Foreign paper cup forming machines generally adopt two indexing turntable structures, and the bottom rolling and mouth rolling are also completed on the two turntables respectively. Due to the superior processing quality of its parts and high level of system integration, its speed can reach 120 pieces/minute Above, but the requirements for paper quality are high. When used domestically, most of them use imported paper, and the equipment market price is high. It is the main direction of molding machine development and has a certain market share.

At the same time, there are vacancies in both domestic and foreign molding equipment, resulting in swollen mechanisms, long production lines, high manufacturing costs, and low competition levels.

At present, there is a huge demand for paper cups in the market, and there is an urgent need to improve and improve the defects of the existing three-turntable, double-turntable and single-turntable machines to meet the market's requirements for price, quality, energy consumption, and efficiency. .
