Mask ear welding machine with cam mechanism

Abstract

The invention relates to the technical field of mask production equipment, in particular to a mask ear welding machine with a cam mechanism. The mask ear welding machine comprises a rack; an ear thread conveying device arranged on the rack and used for conveying an ear thread to a welding point; an ear thread spot welding device used for welding the ear thread conveyed by the ear thread conveyingdevice; and a cam connecting rod mechanism connected with the ear thread spot welding device and used for controlling the ear thread spot welding device to move in the vertical direction. According tothe provided mask ear welding machine, the cam connecting rod mechanism is adopted for controlling the movement of the ear thread spot welding device in the vertical direction, the action is accurateand reliable, the structure is simple and compact, and the transmission efficiency and precision are high. In order to enable each processing procedure of the ear welding machine to be better matched, the transmission of the clamping mechanism is also arranged on the same transmission shaft, and the movement of the clamping mechanism is still controlled by adopting the cam mechanism, so that themechanism relevance is good, the processing rhythm is compact, the gap waiting time of each link is shortened, and the production efficiency of masks is greatly improved.

Description

technical field [0001] The invention relates to the technical field of mask production equipment, in particular to a mask welding earphone with a cam mechanism. Background technique [0002] A mask is a kind of hygiene product, which generally refers to being worn on the mouth and nose to filter the air entering the mouth and nose, so as to prevent harmful gases, odors, droplets, viruses and other substances, and it is also one of the methods to prevent respiratory infectious diseases . It is generally welded with ear straps at both ends, and each ear strap is welded to the upper and lower ends of the mask body at both ends. However, the existing mask machine can only weld one side of the earband by manual operation when welding the earband, and then the operator turns over the head of the mask and welds the other side. It can be seen that the existing manual operation way, the production efficiency is very low. [0003] Patent No. CN111251618A, patent name "An Ear Loop W...

AI Technical Summary

Problems solved by technology

However, the disadvantages of using the cylinder to drive the lifting are that the precision of the cylinder is low, the travel time is long, the speed is slow, the transmission efficiency is low, and the control systems are many and complicated, and the noise is large.
