Background technique

A paper cup is a paper container made by mechanically processing and gluing base paper (white cardboard) made of chemical wood pulp. It has a cup-shaped appearance. Wax-coated paper cups for frozen foods can be used to hold ice cream, jam, butter, etc.

The paper cup preparation device is a device used to prepare paper cups. At present, when the existing paper cup preparation device is used, the traditional preparation and processing production line is converted into a disc shape, saving floor space, and the cup body is realized through a paper cup mold unit The steps of forming, heating the cup body connection, and splicing the cup bottom do not require the paper cup to be transported and re-clamped and positioned multiple times, ensuring the accuracy of the processing and making the processing steps more compact; the clamping structure and the rotary disk A synchronous movement ensures sufficient time for the cup body to be bonded and improves the pass rate. The hinged setting of the rotating block saves pressing time and is more efficient; the stepper motor is easy to control and ensures that each rotation coincides with the processing time; Removable threaded connections allow easy replacement of parts.

However, during the implementation of the above technical solution, it was discovered that at least the following technical problems exist:

It cannot be formed at one time and the production efficiency is low: when using the existing paper cup preparation device, it is necessary to process the cup body and cup bottom of the paper cup at the same time, and then combine the cup body and cup bottom, which requires a lot of time and energy The production efficiency of paper cups is poor.
