Heating head capable of detecting hot-melting piece and heater

Abstract

The invention discloses a heating head capable of detecting a hot-melting piece. The heating head is provided with at least one hot-melting piece detector. The hot-melting piece detectors are metal detectors. The metal detectors are electro-magnetic inducted metal detectors or X-ray detection type metal detectors or ultrasonic detection type metal detectors. The hot-melting piece detectors are cylindrical. The number of the hot-melting piece detectors is four. The four hot-melting piece detectors are distributed on the side face of the heating head. The distribution shape of the four hot-melting piece detectors is rectangular. The detection heads of the hot-melting piece detectors are fixedly connected with the heating head through fixing racks. The hot-melting piece detectors are identical to the heating head in orientation. A heater comprises a heating head, wherein the heating head is the heating head capable of detecting the hot-melting piece. The correct position of the hot-melting piece is easy to find, and caused solder skips, false solder and solder deviations are avoided.

Description

technical field [0001] The invention relates to a heating component and a heating device, in particular to a heating head and a heater capable of detecting a thermal melt sheet. Background technique [0002] Heating and welding is a common processing method in industry and production fields, such as the plastic and rubber industry, transportation such as tunnel engineering, such as plastic film blowing machines, wire drawing machines or injection molding machines, pharmaceutical industry, energy and food industries, etc. Electromagnetic heating is a more popular heating method over the years. Since the ordinary heating coil heating method is usually a contact heat transfer heating method, the heat utilization rate is low, and only 30%-70% of its energy consumption is converted to work. Thermal energy, due to the phenomenon of cooling inertia at the same time as heating, if the heating is not timely, the heating time will be prolonged under the action of heat dissipation, whi...

AI Technical Summary

Problems solved by technology

[0005] First, most tarpaulins are not transparent tarpaulins. In the process of heating and welding, it is difficult to find the correct position of the hot-melt sheet, which can easily cause missing welding, false welding, and partial welding.

[0006] Second, the electromagnetic heating coil is easy to burn out, which affects the normal operation of the welding work

[0007] Third, bipolar transistors (IGBTs) are easy to burn out. After repeated analysis, testing, and research, the cause of burning out bipolar transistors (IGBTs) has not been found

[0008] Fourth, the front end of the heating source is not easy to approach the hot-melt sheet (hot-melt sheet equipped with metal, such as iron mesh, iron nails, etc.), which cannot further improve the heating efficiency

[0009] Fifth, although the hand-held electromagnetic heater is equipped with a variety of heating heads with different front panels, it was found in use that the hot-melt sheet was seriously deformed after being nailed to the wall, and the state was different. The heating head of the panel is far from enough. Even if the heating head of different front panels is doubled, it cannot meet the needs of the work. Moreover, frequent replacement of the heating head will not only increase the labor intensity of the operator, but also affect To work efficiency, can not achieve the best results

[0010] Sixth, since there is a straight groove behind the heating head, the front end of the cavity is provided with a corresponding straight groove to coincide, just like the buckle-type bottle mouth and bottle cap with a chuck and bayonet, forming a plug-in buckle to fix In the work, it is found that the connection fastness of this structure fixed by the plug-in buckle is weak. Because the heating head is heavy, it is easy to fall off from the gun body. In severe cases, the heating head will be damaged.

When working, the operation line with a length of about 16 meters is in the humid and harsh tunnel working environment, which is extremely dangerous
