Abstract

The utility model belongs to a platen heater, particularly to a platen heater used for plastic welding machines. The utility model is characterized in that a snakelike electric heating tube is bent into two planes of which the space is orthogonal; the whole electric heating tube is contained between aluminum plates. The platen heater has the advantages of high heating efficiency, etc., and can uniformly heat the whole body of the substance needing to be heated. The utility model can be arranged on the plastic welding machines for welding various plastic members.

Description

Platen heater

The utility model relates to a kind of electric boiling plate, particularly a kind of electric boiling plate that is applied on the plastic welding machine.

The common electrical heating elements that is used for industrial circles such as aviation, oil, chemical industry, automobile is so at present; Do shell with metal tube, insert the metallic resistance silk in the pipe and do heater, its complementary space is filled magnesia in the pipe, or in metal tube, directly insert the heating wire of the some insulators of series connection, after this electrothermal tube is switched on power supply, the resistance wire heating, because magnesium oxide and insulator have electric insulation, heat conducting character, make metal tube outer surface heating up, can heat static or flow air with it, also can be immersed in water or other liquid and directly heat, and can the melting light metal or do metal die heating usefulness, yet if when some occasion needs whole evenly heat medium, this electrothermal tube just expose it existing can not whole evenly heating, the deficiency that surface area is little.

The purpose of this utility model provides a kind of novel electric boiling plate, and it has solved that existing electric heating tube is existing can not be little to whole heating of medium and surface area, and the deficiency that the heat efficiency is low is specially adapted to Plastic Welding.

The technical solution of the utility model is achieved in that

This kind electric boiling plate is two planes that formed orthogonal space by the electrothermal tube that crawls of the importation of electrothermal tube or output bending and remainder, and whole electrothermal tube is contained within the aluminium sheet, the thickness of aluminium sheet is preferably between the 10-12mm, and two planes that electrothermal tube bends to quadrature equate with place aluminium sheet two outer surfaces distance respectively.Wherein electrothermal tube be with in the copper pipe be with heating wire in series connection heating wire of some insulators or the copper pipe and in managing its complementary space fill magnesium oxide.

The utility model has the following advantages and good effect compared with prior art.At first it can be to the whole evenly heating of the material of need heating.After energized, the electrothermal tube heating is because electrothermal tube is contained within the aluminium sheet fully, and formed plane of electrothermal tube and aluminium sheet outer surface are equidistant, aluminium itself is the good heat transfer conductor, opens temperature so the electric boiling plate surface evenly generates heat, and can reach the effect of even heating.The second, this kind heating plate has the high advantage of the heat efficiency, the contrast electrothermal tube, and electric hot plate has increased heating area, has improved the efficient that electric energy is converted into heat energy, has saved the energy.The 3rd, because this kind heating plate is the planar quadrature type, can be assembled on the Welding plate plastics are welded.

The utility model description of drawings is as follows:

Fig. 1 is an overall structure schematic diagram after the exhibition of the utility model L part of horizontal.

Fig. 2 is the utility model vertical view;

Fig. 3 is the utility model left view;

Fig. 4 is the A-A profile of Fig. 2.

Below in conjunction with the accompanying drawings the utility model is further elaborated with embodiment:

Embodiment: with reference to the accompanying drawings 1,2,3,4, select external diameter 4mm for use, the heating wire of long 1500mm (1), its rated power is 1500 watts, heating wire is stretched in the copper pipe (2) of φ 8 * 1500, in pipe, fill magnesia powder (3) again, then with bending machine with the bending of crawling of its integral body, again its output bending and the electrothermal tube that crawls of remainder are formed two planes of orthogonal space (vertical mutually), in two outlets of copper pipe binding post (7) is installed successively, insulation cushion (9), wiring nut (8), the fixed circle of aluminium circle at the some φ 12 of copper pipe outer surface socket puts it in the pictograph Cast Aluminum Dies then, the aluminium water (4) of casting fusing, treat that it solidifies the back molding, (plugging in thermocouple uses) and other pilot hole (6) in binding post one sidetracking hole (5) are made the single tube bending and are planar quadrature type electric hot plate.The corresponding site that is installed in plastic welding machine can play the effect of heating welding plastic spare.
