Description

Technical Field

[0001] The invention mainly relates to the field of paper cup production, and in particular to a paper cup and a cup bottom cutting die. Background Art

[0002] Disposable paper cups are made by mechanically processing and gluing base paper (white paperboard) made from chemical wood pulp. They are cup-shaped. Paper cups for frozen foods are coated with wax and can hold ice cream, jam, butter, etc. Paper cups for hot drinks are coated with plastic and can withstand temperatures above 90°C and can even hold boiling water. Paper cups are safe, hygienic, light and convenient. They can be used in public places, hotels and restaurants and are disposable items. The paper cup wall and the cup need to be cut by a cutting die during the production process; However, when the paper is cut by the cutting die, the paper is easily attached to the inside of the cutting die, causing the cut paper to accumulate inside the cutting die. When there is a lot of accumulation, the cutting die needs to be cleaned manually on a regular basis.
