Fully automatic coffee cup welding machine and forming die for ultrasonic welding

Abstract

The invention provides a molding die for ultrasonic welding, which includes a cup for placing a welding seat and a forming pressure head; the cup for placing a welding seat includes a cup housing and a conical concave Poor; the inner wall of the conical recess is provided with the first zigzag lines arranged vertically; the forming indenter is provided with a through hole for accommodating the ultrasonic welding head; the lower end of the forming indenter is provided with The first zigzag pattern on the conical concave groove is matched with the second zigzag pattern; the non-woven fabric is placed in the conical concave groove, and the forming pressure head is matched with the conical concave groove and pressed into shape , the zigzag pattern folds and wraps the non-woven fabric neatly to form a cone, the ultrasonic welding head passes through the through hole, and pushes the non-woven fabric into the cup placed in the cup housing shell, so that The non-woven fabric is in contact with the inner wall of the cup through ultrasonic welding, so that the non-woven fabric is neat and beautiful, and firmly bonded to the inner wall of the cup.

Description

technical field [0001] The invention relates to the technical field of coffee cup processing, in particular to a forming die for ultrasonic welding, an ultrasonic welding forming mechanism with the forming die, and a fully automatic coffee cup welding machine with the ultrasonic welding forming mechanism. Background technique [0002] The coffee cup welding machine is a processing equipment that ultrasonically welds the non-woven fabric to the cup body and bonds the inner wall of the cup with the non-woven fabric. [0003] During the molding process of the coffee cup, the non-woven fabric needs to be punched into a circle first, then the non-woven fabric is wrapped into the cup body through the welding head, and finally the cup body and the non-woven fabric are bonded by ultrasonic waves. However, in the prior art, the tapered surface matched by the ultrasonic welding head and the cup body is designed to be a smooth plane; when the non-woven fabric is wrapped into the cup by...

Problems solved by technology

However, in the prior art, the tapered surface matched by the ultrasonic welding head and the cup body is designed to be a smooth plane; when the non-woven fabric is wrapped into the cup by the welding head, the circular non-woven fabric will The non-woven fabric is rolled into a conical shape due to the push of the smooth ultrasonic welding head, so that the non-woven fabric forms irregular folds, so that when the non-woven fabric is ultrasonically welded and bonded to the inner wall of the cup, the finished cup body that is bonded is not neat and beautiful , it will also cause the non-woven fabric to be not firmly bonded to the inner wall of the cup, so that the non-woven fabric and the inner wall of the cup are easily separated, and the welding quality of the coffee cup cannot be guaranteed.
