Ear band detection device for mask

Abstract

The invention discloses an ear band detection device for a mask and relates to the technical field of mask manufacturing equipment. The ear band detection device comprises a detection table, wherein an air cylinder is mounted on the detection table, a lower pressure block is mounted at a telescopic rod end of the air cylinder, rectangular notches are symmetrically formed in the detection table relative to the lower pressure block, the lower surface of the detection table is connected to two detection rods slidably through chutes, a wedged plate and a force cell are connected to the side surface, facing the rectangular notches, of each detection rod, a fixed column is fixed to the lower surface of the detection rod, the lower surface of the detection table is slidably connected to a cam trough plate, two cam troughs are formed in the upper surface of the cam trough plate and the two cam troughs are arranged in a splashed manner, and the cam trough and the fixed column are in clearance fit, and the cam trough moves, so that the two detection rods move close to each other or far away from each other. By arranging the detection rods, the detection rods advance to drive an ear band to stretch. Whether the ear band is welded firmly or not is detected by the force cell, so that the problems that the detection efficiency of an existing ear band of the mask is poor and the detection efficiency is low are solved.

Description

technical field [0001] The invention belongs to the technical field of mask manufacturing equipment, in particular to an ear loop detection device for masks. Background technique [0002] In the manufacturing process of the mask, it is necessary to use a punching machine to process multi-layer non-woven fabrics and filter cloths through edge sealing, cutting and other processes to make the mask body. The ear straps on both sides of the mask are connected to the mask by ultrasonic welding. However, the connection status of the existing earbands needs to be detected manually or by equipment, such as checking whether the earbands are leaking or whether the welding is firm. [0003] If there are defects in the welding of the ear straps of the mask, the ear straps may detach from the mask body during wearing, making the mask unusable. [0004] Manual detection is not only labor-intensive, but also has missed detection. At the same time, the work efficiency of detection is low....

AI Technical Summary

Problems solved by technology

[0006] The object of the present invention is to provide a kind of earband detection device for mask, by setting the detection rod, the earband is driven forward by the detection rod to elongate, and whether the earband is welded firmly by the force sensor, which solves the problem of the existing mask earband Poor detection effect and low detection efficiency
