Cup-mouth copying rotary welding machine

Abstract

The invention relates to a cup-mouth copying rotary welding machine, which comprises a stander, a rotatable rotation fixing mould which is arranged on the stander and is used for fixing a cup, and a welding device. The welding device comprises a welding torch, a fixing seat for fixing the welding torch, a horizontal sliding seat which is slidingly arranged on the stander in the radial direction of the cup, a horizontal pinch roller which is rotatablely arranged on the horizontal sliding seat, a vertical sliding seat which is slidingly arranged on the horizontal sliding seat in the vertical direction, and a vertical pinch roller which is rotationally connected with the vertical sliding seat through a pivot. The outer periphery of the vertical pinch roller is pressed tightly on the cup-mouth upper surface of the cup, and the outer periphery of the horizontal pinch roller is butted against the cup-mouth outer wall surface of the cup; and the vertical sliding seat is fixedly connected with the fixing seat. The rotary welding machine has the advantages of good welding quality, smooth welded cup-mouth surface and beautiful product.

Description

technical field [0001] The invention relates to a welding device for processing cups. Background technique [0002] Welding equipment is well known in the prior art and usually includes a welding torch. The quality of welding is not only affected by the solder, how to fix the object to be processed during welding and the degree of cooperation between the welding torch and the part to be processed are key factors affecting the quality of welding. [0003] Water cups such as thermos cups usually adopt welding methods when sealing the bottom. For example, after the inner layer and the outer layer of the thermos cup are made separately, the gap between the inner cup mouth and the outer cup mouth is sealed by welding. When the machine is used to process the mouth of the cup, the relative position of the welding torch and the mouth of the cup is fixed. For the cup whose surface is not completely flat and the mouth of the cup is not round, it is difficult for the welding torch to ...

AI Technical Summary

Problems solved by technology

[0003] Water cups such as thermos cups usually adopt welding methods when sealing the bottom. For example, after the inner layer and the outer layer of the thermos cup are made separately, the gap between the inner cup mouth and the outer cup mouth is sealed by welding. When the machine is used to process the mouth of the cup, the relative position of the welding torch and the mouth of the cup is fixed. For the cup whose surface is not completely flat and the mouth of the cup is not round, it is difficult for the welding torch to have a good fit with the mouth of the cup everywhere. The cooperation of the cup will easily cause the surface of the cup mouth to be uneven after welding, which will affect the appearance of the product
