Full-automatic coffee cup welding machine and forming die for ultrasonic welding

Abstract

The invention provides a forming die for ultrasonic welding. The forming die comprises a cup body placing welding seat and a forming pressing head. The cup body placing welding seat comprises a cup body containing shell and a conical groove formed in the cup body containing shell. A first sawtooth pattern arranged in the vertical direction is arranged on the inner wall of the conical groove. A through hole allowing an ultrasonic welding head to penetrate through is formed in the forming pressing head, and a second sawtooth pattern connected with the first sawtooth pattern on the conical groovein a matched mode is arranged at the lower end of the forming pressing head. Non-woven fabric is placed in the conical groove, the forming pressing head is connected with the conical groove in a matched mode to be subjected to press-fitting forming, the sawtooth patterns uniformly fold and wrap the non-woven fabric to form a conical body, and the ultrasonic welding head penetrates through the through hole and pushes the non-woven fabric into a cup body placed in the cup body containing shell, so that the non-woven fabric and the inner wall of the cup body are bonded by ultrasonic welding, andthe non-woven fabric is neat and attractive and firmly bonded to the inner wall of the cup body.

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.
