Shearing mechanism for assembly of cup lid

Abstract

The invention relates to the field of manufacturing industries of articles for daily use, in particular to a shearing mechanism for assembly of a cup lid. The shearing mechanism comprises a base, a shearing structure, a supporting structure, a clamping structure, an adjusting structure and a controlling structure, wherein through arrangement of the shearing structure, the cup lid can be sheared and ground; through arrangement of the supporting structure, a cup lid blank body can be moved at any angles, so that the cup lid blank body can be cooperated with the shearing structure to perform theprocedures of shearing and grinding; through arrangement of the clamping structure, the cup lid blank body can be clamped, and cup lid blank bodies with different diameters can be clamped; through arrangement of the adjusting structure, the adjusting structure is controlled so as to drive the clamping structure to clamp the cup lid blank body, and due to the adjusting structure, the phenomenon that the cup lid blank body cannot be easily loosened even if vibration occurs in shearing and grinding processes also can be ensured, and the stability of the clamping structure is ensured; and througharrangement of the controlling structure, the adjusting structure and the supporting structure can be controlled more conveniently through hands, and thus, convenience for operation is improved.

Description

technical field [0001] The invention relates to the field of daily necessities manufacturing industry, in particular to a shearing mechanism for assembling cup lids. Background technique [0002] Water cups are common items in daily life. There are many kinds of water cups, but the lids of most water cups are made of plastic. The plastic water cup lids are mainly made by injection molding process. Molten plastic is injected into the mold and cooled. After that, a cup cover of a specific shape can be formed, and the cup cover made by injection molding, like wood products, usually has the problem of leftovers or burrs on the finished blank, so the blank of the cup cover The process of shearing and grinding is also required to remove surface scraps and burrs. [0003] For the semi-automatic cup cover equipment workshop, when the blank body of the cup cover is sheared, it is not convenient for cutting and grinding due to the inconsistent shape and position of the leftover mater...

AI Technical Summary

Problems solved by technology

[0003] For the semi-automatic cup cover equipment workshop, when the blank body of the cup cover is sheared, it is not convenient for cutting and grinding due to the inconsistent shape and position of the leftover material and the burr of each cup cover blank, so the cup cover blank The shearing and grinding process is mainly completed by manual cooperation with machinery. When the existing shearing mechanism is in operation, the worker mainly holds the cup lid body and slowly moves to the shearing tool for cutting and grinding. The worker's hand often needs to be close to the cutter, so there is a big safety hazard, that is, the worker's hand is prone to be injured by the cutter of the shearing mechanism
