Welding module for a nonwoven bag making machine

Abstract

The utility model relates to a kind of welding module of non-woven fabric bag making machine, including substrate, workbench, cylinder and ultrasonic welding plate, workbench is fixedly installed at the top of substrate, the fixed portion of cylinder is fixedly installed at the top of workbench, the movable portion of cylinder passes through and extends to the top end bottom of workbench, the movable portion bottom end of cylinder is fixedly installed with fixed plate, cylinder is communicated with two five-way solenoid valves, the top of substrate is provided with ultrasonic welding plate, the bottom of fixed plate is fixedly installed with knife plate, by using above-mentioned technical scheme, the double-layer non-woven fabric to be welded is placed at the top of ultrasonic welding plate, cylinder drives fixed plate to move downward, to drive knife plate to move downward, so that knife plate presses double-layer non-woven fabric downward, then ultrasonic welding plate generates high-frequency vibration, vibration energy is focused on the joint surface of non-woven fabric, heating is generated by the friction of the contact surface with knife plate, and then the fusion of double-layer non-woven fabric is realized, and double-layer non-woven fabric is made into bag.
