Description

Technical Field

[0001] This utility model relates to the field of paper cup production technology, specifically to a paper cup machine's rim-rolling mechanism. Background Technology

[0002] In the automated production of paper cups, the rim rolling is a crucial final step. It refers to the mechanical curling of the paper at the rim edge into a smooth, continuous ring after the cup body and base are joined. The rim rolling mechanism is one of the core components of a paper cup machine, and its performance directly determines the consistency of paper cup quality, production efficiency, and scrap rate. With the increasing demand for high-speed production and high-quality paper cups, the limitations of traditional rim rolling mechanisms are becoming increasingly apparent.

[0003] In existing technologies, when traditional edge-rolling mechanisms are running at high speeds, the continuous high-speed friction between the edge-rolling wheel and the paper edge of the cup mouth causes accelerated wear, and after a period of operation, the edge-rolling quality begins to decline.

Then, the airflow from the air compressor blows out from the bottom of the cup-down guide rod 1205, blowing the paper cup down and realizing the cup-down operation.

[0026] Implementation Plan: By connecting the eccentric shaft connecting rod 1401 to an external starting point, the entire assembly reciprocates up and down. During this process, the eccentric shaft connecting rod 1401 swings around the pin 1404. The pre-rolling mechanism 11 reciprocates up and down to first roll the paper cup. When the pre-rolled nylon 1108 touches the paper cup, the pre-rolled nylon buffer spring 1109 can act as a buffer. The pre-rolled nylon 1108 rolls the paper cup into a preliminary arc edge. The final rolling mechanism 10 rolls the paper cup into a preliminary arc edge in the process of the pre-rolling mechanism 11. While pressing, the final nylon 1009 rolls the paper cup into a rounded and tight edge. The oiling mechanism 13 lubricates the pre-rolling mechanism 11 and the final rolling mechanism 10 to prevent wrinkles and uneven rolling of the cup, thereby improving product quality. The lower cup blowing mechanism 12 reciprocates, and the rubber block 1207 touches the paper cup. At this time, the lower cup buffer spring 1206 buffers the left and right sides. Then, the airflow from the air compressor blows out from the bottom of the lower cup guide rod 1205, blowing the paper cup down to complete the lower cup operation.
