Heating end and heater

Abstract

The invention discloses a heating end and a heater. The heating end comprises a shell; a locking matching part is arranged behind the shell; the locking matching part comprises a locking neck and locking heads; the locking neck is a circular annular body which extends from the back part of the shell backwardly; the locking heads are multiple arc-shaped flanges which extend outwardly from the backpart of the outer side surface of the locking neck in the radial direction; the locking heads are uniformly distributed in the circumferential direction of the locking neck; the arc length of the locking heads is less than or equal to two times of the arc-shaped distance between two adjacent locking heads; the number of the locking heads is at least two; the number of the locking heads can be two,three or four; an opening is formed in the outer side of each locking head; and the opening is close to one end of each locking head. The heater comprises the heating end which is the abovementionedheating end. The connection firmness of the heating end can be greatly improved; an operator can hold a gun type electromagnetic heater by only one hand; and the heating end does not fall off easily,damage of the heating end caused by falling off can be avoided, and the heating end is very convenient to use.

Description

technical field [0001] The invention relates to a heating component and a heating device, in particular to a heating head and a heater. 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, while electromagnetic induction heating can u...

Problems solved by technology

[0005] First, since there is a straight groove behind the heating head, the front end of the cavity is provided with a corresponding straight groove to match, just like the snap-on bottle mouth and bottle cap with a chuck and a bayonet, forming a plug-in buckle and fixing 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.

In order to prevent the heating head from falling off, the operator has to hold the electromagnetic heater with both hands, or hold the heating head upwards, which is inconvenient to use

[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, 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.

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
