Positioning mechanism for can packaging

Abstract

The invention discloses a positioning mechanism for sealing cans. The positioning mechanism for sealing cans comprises a positioning body, pin shafts, overturning bodies, torsion springs, positioning wheels and a limit rod, wherein the pin shafts are mounted at the upper part and the lower part of the positioning body; the positioning body is respectively articulated with the overturning bodies through the pin shafts at the upper part and the lower part of the positioning body; the positioning wheels are rotatably supported on the overturning bodies through positioning wheel shafts; the torsion springs are mounted on the pin shafts; two ends of each torsion spring are respectively clamped on the pin shaft and the positioning body; the limit rod is located at the top of the overturning body at the upper part, is connected with the overturning body or is integrally manufactured with the overturning body; an arc-shaped opening is formed in the middle of the positioning body at one side of the overturning body. The positioning mechanism for sealing cans is simple in structure and low in cost, can be self-adjusted so as to adapt to the cans with different opening diameters, has no damage to the surfaces of the cans in use, and can also highly adapt to the sealing of the cans in the vacuumizing process; limit pillars at the upper parts of the overturning bodies are capable of preventing caps of the cans from being thrown out when the cans flow among various stations.

Description

technical field [0001] The invention relates to a food packaging technology, in particular to a positioning mechanism for tin can packaging. Background technique [0002] In canned packaging, can sealing is a key process. In the process of can sealing, the positioning of the can, and the flow to vacuum and nitrogen filling, until the can is sealed, the whole process is realized on the rotary table. Therefore , tank positioning is a very important device. [0003] The positioning of traditional seaming uses hydraulic clamps to clamp the cans and push the cans to the operating position. It is often necessary to adjust, and a slight improper adjustment will easily damage the surface of the jar. At the same time, when the flow is transferred to each station, the speed is too fast, and the lid will be thrown out under the action of inertia. Contents of the invention [0004] The purpose of the present invention is to provide a simple structure, low cost, can self-adjust to ad...
