Ultrasonic pressing welding device for double-layer non-woven fabric

Abstract

The invention provides an ultrasonic pressing welding device for double-layer non-woven fabric. The ultrasonic pressing welding device comprises a rack, a group of front material passing rollers, a traction roller, an embossing wheel frame, an ultrasonic welding head frame and rear material passing rollers, and the front material passing rollers, the traction roller, the embossing wheel frame, the ultrasonic welding head frame and the rear material passing rollers are sequentially arranged on the rack. A swing arm is arranged below the front material passing rollers, the right end of the swing arm touches a traction roller motor switch to start a traction roller motor, the traction roller motor is connected with the traction roller, the traction roller is connected with an embossing wheel, the embossing wheel is fixed to the embossing wheel frame, and an ultrasonic welding head is fixed to the ultrasonic welding head frame. The traction roller operates to drive the embossing wheel to rotate, a traction pressing roller pulls the double-layer non-woven fabric penetrating through the space between the traction pressing roller and the traction roller to move forwards, the embossing wheel moves downwards under the action of an air cylinder, and the embossing wheel and the ultrasonic welding head conduct pressing welding on the two side edges of the double-layer non-woven fabric at the same time. The ultrasonic pressing welding device not only can adapt to embossing wheels with various different patterns to be used for pressing welding of non-woven fabric with different widths, but also is stable in pressing welding quality.

Description

technical field [0001] The invention relates to the field of pressing and welding of non-woven fabrics, in particular to an ultrasonic pressing and welding device for double-layer non-woven fabrics. Background technique [0002] Non-woven (non-woven) wrapping materials in medical sterilization wrapping materials are generally cut into square or rectangular single pieces of different specifications for medical institutions to wrap various instruments for sterilization. [0003] However, some larger or heavier instruments are easy to cause damage when wrapping instruments for sterilization, so many customers choose to combine two pieces of non-woven fabrics for wrapping, and two pieces of non-woven fabrics that are not connected are not convenient for wrapping operations, so , two pieces of non-woven fabrics need to be ironed and glued together before use. In this way, the two layers of non-woven fabrics need to be bonded together first, and then the equipment for cutting is c...
