High-frequency soldering assembly for composite soft tube shoulder

Abstract

The invention relates to a high-frequency welding module for composite hose shoulder, belonging to the constitution of high-frequency welding to composite hose shoulder except aluminum-plastic composite hose in package hose sealing welding field. The welding module comprises mandrel body with hose cylinder docking with welding hose shoulder and above mentioned high-frequency welding head. Thereinto, the mandrel body comprises mandrel bar and mandrel head allocated at the front end and mandrel figure of hose cylinder combining hose shoulder is formed integrally. The high-frequency welding head comprises base. Thereinto, single-turn high-frequency induction coil clings to cooling water pipe to form the constitution device set in circular high-frequency magnetic body, which can cool the single-turn high-frequency induction coil directly. All welding regions are integrated to form the welding forming cavity coincided with welded region of hose shoulder and the extension region. The shoulder part coincided with the integral welding forming cavity is formed at the lower of mandrel head. Guide circular block device, on which magnetic shielding ring is embedded, is set on the base. The invention can make welding shoulder form in one time and the welded surface is brightness. The rate of finished product is high.

Description

technical field [0001] The invention belongs to the field of packaging hose sealing welding, in particular to the high-frequency welding structure of the shoulder of the composite hose other than the aluminum-plastic composite hose. Background technique [0002] Known technology for high-frequency heat sealing of aluminum-plastic composite hose packaging, such as the published Chinese patent application 02104536.4 "High-frequency heat-sealing device", the device is composed of free-opening and closing sealing jaws and opposite-to-staggered openings It is used to heat-seal the tube-shaped packaging material in the transverse direction under the liquid surface. On the active surface of the high-frequency coil that is set on the same surface as the sealing jaw, there is a device that can be squeezed in a The left and right sides are circular and elongated in the central part of the sealing tape area and contain a part of curved protrusions, and the active surface adjacent to th...

Problems solved by technology

[0005] When welding the shoulders of aluminum-plastic composite hoses such as toothpaste hoses and ointment hoses, the high-frequency welding devices used in the market require a high-frequency heating power supply, generally up to 6KW, due to the high-frequency induction coil. The magnetic field line cuts the aluminum foil on the top of the tube through the ceramic welding ring to generate eddy current, thereby increasing the magnetic resistance and reducing the heating efficiency. To solve this problem, people need to pre-heat the tube shoulder with hot air at the previous station to ensure that the tube and tube The welding of the tube shoulder is firm, so the problems of complex manufacturing process, high power consumption of production line equipment and low manufacturing efficiency in the conventional technology need to be solved urgently
