Upper ear belt mechanism of mask machine

Abstract

The invention provides an upper ear belt mechanism of a mask machine. The upper ear belt mechanism comprises a machine box, a working table is arranged at the upper end of the machine box, a mask piece conveying belt and the upper ear belt mechanism are fixed to the top face of the working table, the upper ear belt mechanism comprises a guiding device, a transmission device, a welding device, a wire clamping device and a wire cutting device, and the transmission device further comprises a motor, a driving gear and a driven gear. The motor drives the driving gear to rotate, the driving gear is connected with the driven gear through a belt, a plurality of fixing seats which are uniformly distributed are arranged on the belt, each fixing seat is fixedly provided with one wire clamping device and one welding device, and the wire cutting device is used for cutting off an ear wire on each wire clamping device, so that the ear wire becomes a single ear belt. The guide device enables the welding gun of the welding device to be pressed downwards, and the welding gun enables the ear belts and the mask pieces conveyed by the mask piece conveying belt to be welded together to form a complete mask.

Description

technical field [0001] The invention belongs to the field of mask machines, in particular to an upper ear strap mechanism of a mask machine. Background technique [0002] At present, the mask upper earband machine generally includes two types of turntable-type upper earband mechanism and clamp arm-type upper earband mechanism. Among them, the turntable-type upper earband mechanism has its ear wires rotated by the turntable to determine the length, and then the thread cutting device cuts the ear wires, and finally The upper earband is welded by the welding device, and the clamp arm type upper earband mechanism pulls the wire through the wire pulling device, the clamp arm fixes the length of the clamp line, and then cuts the line through the wire cutting device, and then flips the clamp arm and cooperates with the welding device to weld the earband to complete the upper earband. Earbands, these two types of upper earband mechanisms are independent of each other, and each devic...

[0002] At present, the mask upper earband machine generally includes two types of turntable-type upper earband mechanism and clamp arm-type upper earband mechanism. Among them, the turntable-type upper earband mechanism has its ear wires rotated by the turntable to determine the length, and then the thread cutting device cuts the ear wires, and finally The upper earband is welded by the welding device, and the clamp arm type upper earband mechanism pulls the wire through the wire pulling device, the clamp arm fixes the length of the clamp line, and then cuts the line through the wire cutting device, and then flips the clamp arm and cooperates with the welding device to weld the earband to complete the upper earband. Earbands, these two types of upper earband mechanisms are independent of each other, and each device is controlled by multiple cylinders. The cooperation between the various devices lacks continuity, so that the waiting time from one process to the next process Longer, causing the problem of low production efficiency of the mask machine
