High-speed end sealing wire structure

Abstract

The invention belongs to the technical field of packaging mechanical equipment, and particularly relates to a high-speed end sealing wiring structure, one end of an external power line is fixed on a copper screw, the other end of the external power line enters an end sealing shaft through an inclined hole and then is connected with a collector ring, a carbon brush extends out under the action of elastic force and is attached to a copper plate, the external power line is connected with a heating pipe through the collector ring, the end sealing shaft, the copper screw, the copper plate, the carbon brush, a hollow copper stud and a copper block to achieve electric heating, in the operation process of equipment, only the carbon brush and the copper plate of a conductive part rub relatively, and the heating pipe, the external power line and a sealer do not move relatively, the external power line cannot leak electricity due to repeated bending, so that the problem of line breakage is solved; the structure is simple, active disconnecting is carried out at the position where the external power line easily generates relative motion, the carbon brush is connected with the copper plate, so that the carbon brush is always tightly combined with the copper plate when sliding on the copper plate, the external power line on one side of the copper plate is relatively static, and the external power line on one side of the carbon brush is also relatively static.

Description

Technical field: [0001] The invention belongs to the technical field of packaging machinery and equipment, and in particular relates to a high-speed end sealing wire structure, which solves the problem of disconnection of packaging machinery and avoids the risk of electric leakage. Background technique: [0002] Packaging bag is a bag for packaging goods, which makes it convenient to transport and store goods in the process of production and circulation. It is widely used in daily life and industrial production. Items such as biscuits, bread, daily necessities and medicine boards are packaged in packaging bags. For sale. The packaging bag is produced by a pillow packaging machine or a vertical packaging machine. For example, the reciprocating packaging machine disclosed in Chinese patent 202021632354.5 includes a packaging machine body. The top of the packaging machine body is provided with a packaging mechanism. The top of the packaging machine body is fixed and installed ...

AI Technical Summary

Problems solved by technology

The material of the packaging bag is generally POF heat-shrinkable film, composite film, aluminum-plated or pure aluminum. When the goods have high requirements on airtightness or light-proof performance, the thickness of the packaging film needs to be increased moderately, which will lead to difficulties in the production of the packaging machine. increase

For the packaging of thick packaging films, reciprocating packaging machines or rotary reciprocating packaging machines are generally used. However, the wires of the end-sealing heating tube and the end-sealing sealer will move relative to each other during operation, and the power wires will be frequently twisted. Layers are easily cracked, resulting in leakage, and even the power cord is broken
