Full automatic ultrasonic welding machine for plastic pen

Abstract

The invention discloses a full automatic ultrasonic welding machine for a plastic pen. The full automatic ultrasonic welding machine for the plastic pen comprises a mounting rack, an ultrasonic generator, energy converters and energy converter guide rail brackets, wherein an energy converter sliding power mechanism is arranged on the energy converter guide rail brackets; the symmetric center position of the two energy converter guide rail brackets is provided with a welding mechanism for two ends of the plastic pen; the welding mechanism for two ends of the plastic pen comprises a one-by-one pen feeding mechanism, a delivery mechanism, a plastic pen clamping welding mechanism and a pen arranging mechanism; the plastic pen clamping welding mechanism comprises a lower mould, an upper mould, and a power mechanism for joining and separating the moulds; the lower mould and the upper mould are correspondingly provided with a plurality of mould dents matched with the plastic pen; and the left side and the right side of the joint position of the lower mould and the upper mould, and the left ultrasonic welding head and the right ultrasonic welding head which are arranged on the left energy converter and the right energy converter are oppositely arranged in a matching way. The full automatic ultrasonic welding machine for the plastic pen has the advantages of high work efficiency and beautiful weld appearance.

Description

technical field [0001] The invention relates to a welding machine, in particular to a full-automatic ultrasonic plastic pen welding machine suitable for connecting a plastic pen holder, a pen back cover and a pen tip sleeve. Background technique [0002] At present, a new type of manufacturing plastic pen (color plastic pen) process is favored by many consumers. The production process is: use a tube pulling machine to directly pull out the formed long plastic pen tube, and then cut it into a section of the pen tube. , and then put the pen core, and install the pen back cover and the nib cover at both ends of the pen holder, and then weld the pen back cover and the nib cover to the pen holder through ultrasonic welding. The production process of this kind of plastic pen is simple, the production cost is reduced, and it is especially suitable for the large-scale production of the assembly line. However, this process also has a new bottleneck: the welding speed of the pen back ...

AI Technical Summary

Problems solved by technology

The production process of this kind of plastic pen is simple, the production cost is reduced, and it is especially suitable for the large-scale production of the assembly line. However, this process also has a new bottleneck: the welding speed of the pen back cover and the nib cover is far behind the speed of the assembly line. , the current welding process is to use a vertical ultrasonic plastic welding machine to weld one end of the pen holder at a time and then turn around and then weld the other end. The skilled workers of each welding machine can only weld about 500-800 pens per hour, which is far from satisfying the production Require
