Abstract
The invention provides a glass tube heater of screw-type fluorescent tube bender, which comprises a first furnace and a second furnace which are open-close engaged, wherein the middles or the portions near the middle of the first and second furnaces are respectively provided with a heating blank area, the first and second furnaces are respectively arranged with electric heaters at two sides of the heating blank area. The technical scheme of the invention can heat glass tube uniformly and quickly, while the open-close furnaces can be engaged with mechanical arm, to apply screw-type fluorescent tube bender, to automatically bend glass tube, reduce labor strength, improve production efficiency and confirm product quality.
Description
Technical field
The present invention relates to make the mechanism of helical fluorescent lamp tube, relate in particular to lighting tube heating mechanism wherein.
Background technology
At present, the fluorescent tube of helical type florescent lamp tube-bending machine adopts manual operations, and its process furnace is formed around round combustion chamber by an electric stove wire.During operation, get a glass-tube and be placed on the stove internal heating, see after glass-tube softens fully and immediately glass-tube is taken out process furnace, be placed in the middle of the mould, both hands keeping parallelism position, the switch that foot-operated simultaneously mould rises carries out bend pipe, when glass-tube has been bent soon, and inlet open, to glass-tube blowing bulging, after seeing that glass-tube on the mould sticks out fully, close intake valve, put down a glass-tube then and heat, both hands are arrested two pin of the glass-tube on the mould again, open the air valve that mould descends, the glass-tube after being shaped is taken out, carry out the operation cycle of next root glass-tube bend pipe again.In heating process, entirely by manual operation and control, difficult quality is stable, easily because of heating problems affect glass-tube bend pipes such as inhomogeneous.
Summary of the invention
Technical problem to be solved by this invention provides a kind of glass-tube heating unit that can make the helical type florescent lamp tube-bending machine that glass-tube is heated evenly.The present invention by the following technical solutions for this reason: it comprises first body of heater and second body of heater that folding cooperates, the centre of first body of heater and second body of heater or close middle part are respectively equipped with the heating neutral area, and first body of heater and second body of heater are respectively equipped with an electric heating element in the both sides of heating neutral area.Owing to adopt technical scheme of the present invention, glass-tube is heated evenly, heating is fast, the body of heater of folding can cooperate with mechanical manipulator, thereby can be applied to the helical type florescent lamp tube-bending machine, realizes glass-tube automatization bend pipe, reduce labour intensity, enhance productivity, guarantee quality product.
Description of drawings
Fig. 1 is the side-view of one embodiment of the present invention.
Fig. 2 is first body of heater or the combustion chamber of second body of heater and the side-view of nichrome wire combination among Fig. 1.
Fig. 3 is first body of heater or the combustion chamber of second body of heater and the front schematic view of nichrome wire combination among Fig. 1
Embodiment
With reference to accompanying drawing.The present invention includes the centre of first body of heater 1 that folding cooperates and second body of heater, 2, the first bodies of heater and second body of heater or be respectively equipped with heating neutral area 3, the first bodies of heater and second body of heater is respectively equipped with an electric heating element in the both sides of heating neutral area near the middle part.
In the present invention, it is the same that first body of heater 1 and second body of heater 2 can be made, and they are respectively equipped with tabular combustion chamber 4 and shell 5, and described combustion chamber is provided with the locating structure of an electric heating element, and the length of combustion chamber can customize according to the length of glass-tube.Be provided with lagging material 6 between shell and combustion chamber, such as asbestos.
Described an electric heating element is located at the 11 and second furnace body inside surface 21, first furnace body inside surface respectively, described combustion chamber is provided with the locating slot 7 as an electric heating element locating structure, like this, can make the heating effect of electrical heating element reach best, help glass-tube and be heated evenly.
In the present embodiment, described an electric heating element is a nichrome wire 8.On the combustion chamber of the present invention's first body of heater 1 and second body of heater 2 each be wound in two semi-enclosed pipelines respectively by two nichrome wire 8, and, two nichrome wire on the same body of heater be divided into combustion chamber about, the combustion chamber between them for the heating neutral area 3.8 nichrome wire heads are connected on the controller 10 by screw 9, and 4 nichrome wire are connected respectively to 4 temp controlled meters 20 on the controller.During work, 4 temperature control tables carry out the temperature adjustment heating to 4 nichrome wire respectively.
In the present invention, heating neutral area 3 is meant does not establish an electric heating element in this interval, or is markedly inferior to an electric heating element density in its both sides body of heater in this interval an electric heating element density.Like this, can avoid in heating unit, occurring the low phenomenon of the high both sides of medium temperature temperature, glass-tube is heated evenly in heating unit, can help the operation of mechanize bend pipe.
In the helical type florescent lamp tube-bending machine, the folding of first body of heater 1 and second body of heater 2 cooperates and can drive realization by cylinder or other mechanical actuation devices.
