The welding gun head for the plastic wound pipes provided by the utility model has the advantages of small structure, economization and practicability, can be used on small diameter series extruders, has wide welding surface, and can ensure the quality of the welding connection between the plastic wound pipes and injection molding faucet pipe fittings.
Description
Technical field
The utility model relates to a kind of process equipment of plastic pipe, relates in particular to a kind of welding gun head of plastic spiral pipe.
Background technology
Traditional ground draining blow-off pipe that buries is mainly used these class pipe-line systems such as concrete or reinforced concrete pipiline.The sealing of pipe of cement is very poor, the straight cut pipe of concrete only depends in the junction smears a circle concrete sealing, be difficult in the construction guarantee not leak, pipe of concrete belongs to rigid pipe in addition, there be mobile (as the soil differential settlement) just can cause the junction to destroy slightly, when setting of ground, interface very easily breaks, and causes secondary pollution.Moreover sanitary sewage, rainwater etc. have corrosivity usually, and the corrosivity of trade effluent is bigger, use metal, cement buried drain pipe to carry, and are subjected to corrosivity easily.In addition, the general weight of this class tubing is big, and installing needs main equipment, and efficiency of construction is low.The life-span of pipe of concrete is short, generally has only 15 years.
Compare with traditional pipe-line system, the plastic underground drainpipe has the following advantages: 1, do not leak, prevent contaminated environment; 2, belong to flexible pipe, more can realize the pipeclay acting in conjunction; 3, good hydraulic characteristic(s); 4, long service life can be with 50 years; 5, in light weight, corrosion-resistant, nontoxic, wear-resistant; 6, be convenient to lay installation; 7, comprehensive cost is low; 8, good serviceability and quick for installation.Thereby the plastic underground drainpipe develops rapidly in recent years.
But the plastic underground drainpipe also has a problem of expanding with heat and contract with cold, and this problem can be solved by the type of attachment that changes the plastic construction wall tube material, and adopting unidirectional socket joint connected mode is exactly a kind of good settling mode.This connected mode makes the end of each root tubing have a bell and spigot, and its diameter is greater than plastic winding pipes, because the forming technology of wrapped tube, also can't once-forming.Need produce wrapped tube and injection moulding bell and spigot pipe fitting respectively, then they are welded together with plastics fusion welding rod (claiming PUR again), the solder bond face is wide in the axial direction in this welding requirements, also certain thickness to be reached, the defective that once-forming brings and the problem of not prison welding can be avoided not being like this.Therefore, the fusion weld quality of plastic winding pipes and injection moulding bell and spigot pipe fitting has determined the construction quality of plastic underground drainpipe.
The utility model content
The purpose of this utility model, exactly for provide a kind of can be in high quality with plastic winding pipes and injection moulding bell and spigot pipe fitting fusion weld welding gun head of plastic spiral pipe together.
In order to achieve the above object, the utility model has adopted following technical scheme: a kind of welding gun head of plastic spiral pipe, be used for plastic spiral pipe and injection moulding bell and spigot pipe fitting being welded to connect by the fusion welding rod, comprise cavity, two end plates and heating element heater, two end plates is sealed in the two ends of cavity, and heating element heater is arranged in the entity of two end plates and cavity;
Described cavity is sequentially with charging hole, first storage cavity, first passage, second storage cavity and second channel from top to bottom and is interconnected, and second channel is the exit passageway of fusion welding rod.
Described first storage cavity, first passage, second storage cavity and second channel length direction extension and the length along cavity respectively are identical, wherein, first storage cavity and second storage cavity all are the Circularhole diameter of the Circularhole diameter of the circle hole shape chamber and first storage cavity greater than second storage cavity; First passage and second channel all are the width of the width of narrow slit shape passage and first passage less than second channel.
Described cavity is constituted by two half identical cavitys of symmetrical configuration.
The unified a plurality of installing holes that are used to install heating element heater that connect along its length that are provided with on described cavity and the two end plates.
Welding gun head of plastic spiral pipe structure of the present utility model is small and exquisite, economical and practical, can use on the extruder of minor diameter series and welds face width, can guarantee the quality that is welded to connect between plastic spiral pipe and the injection moulding bell and spigot pipe fitting.

The specific embodiment
Referring to Fig. 1, Fig. 2, Fig. 3, the utility model welding gun head of plastic spiral pipe comprises cavity 1, two end plates 2 and heating element heater (not shown come out), and two end plates 2 is sealed in the two ends of cavity 1, and heating element heater is arranged in the entity of two end plates and cavity.
Cavity 1 in the utility model is sequentially with charging hole 11, first storage cavity 12, first passage 13, second storage cavity 14 and second channel 15 from top to bottom and is interconnected, and second channel 15 is the exit passageway of fusion welding rod.First storage cavity 12, first passage 13, second storage cavity 14 and second channel 15 length direction extension (or perforation) and the length along cavity 1 respectively are identical, wherein, first storage cavity 12 and second storage cavity 14 all are the Circularhole diameter of the Circularhole diameter of the circle hole shape chamber and first storage cavity 12 greater than second storage cavity 14; First passage 13 and second channel 15 all are the width of the width of narrow slit shape passage and first passage 13 less than second channel 15.
Cavity 1 in the utility model also can be constituted by two identical half cavity 1a and 1b of symmetrical configuration as shown in Figure 4.
The unified a plurality of installing holes 16,21 that are used to install heating element heater that connect along its length that are provided with on cavity 1 in the utility model and the two end plates 2.
The utility model welding gun head of plastic spiral pipe is used for by the fusion welding rod plastic spiral pipe and injection moulding bell and spigot pipe fitting being welded to connect, it uses example as shown in Figure 5, and shown in the figure, 3 is plastic spiral pipe, 4 are injection moulding bell and spigot pipe fitting, and 5 is the welding rod that welding is got on.Adopt the welding process of the utility model welding gun head of plastic spiral pipe to be, the fusion welding rod that extruder is extruded enters cavity 1 by charging hole 11, enter first storage cavity 12 subsequently, because the width of first passage 13 is little, the fusion welding rod is squeezed and because of the fusion welding rod is easy to flow, comes thereby sprawl herein at first storage cavity, 12 places.Then the fusion welding rod enters second storage cavity 14, and comes out through second channel 15 extruding from here, is bonded in the tubing and the pipe fitting place that need welding subsequently.This kind structure is small and exquisite, and is easy for installation, economical and practical, can solve solder side well and want wide problem.
