Abstract
The invention provides a welding gun head of a plastic spiral pipe, which comprises a cavity, two end plates and a heating element. The two end plates seal the two ends of the cavity, the heating element is arranged in an entity with the two end plates and the cavity; the cavity is sequentially provided with a feeding hole, a first material storage chamber, a first channel, a second material storage chamber and a second channel from top to bottom, the feeding hole, the first material storage chamber, the first channel, the second material storage chamber and the second channel are communicated with each other, and the second channel is an outlet channel of a molten welding rod. The welding gun head of the plastic spiral pipe has a small structure, is economical and practical, and can be applied in series extruders with small diameters. Moreover, the welding gun head of the plastic spiral pipe has a wide welding surface and can ensure the quality of the welding connection of the plastic spiral pipe and the injection faucet pipeline.
Description
Technical field
The present invention relates to a kind of process equipment of plastic pipe, relate 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 this type 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, is difficult in the construction guarantee not leak, and pipe of concrete belongs to rigid pipe in addition; There is mobile (like 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 receive corrosivity easily.In addition, the general weight of this type 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 solve through 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; Weld together them with plastics fusion welding rod (claiming PUR again) then; The solder bond face is wide in the axial direction in this welding requirements; Also certain thickness to be reached, the defective and the not firm problem of welding that are not that once-forming brings can be avoided 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.
Summary of the invention
The object of the invention, 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 present invention 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 through 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 invention is small and exquisite, economical and practical, can on the extruder of minor diameter series, use and the welding face width, can guarantee the quality that is welded to connect between plastic spiral pipe and the injection moulding bell and spigot pipe fitting.
Description of drawings
Fig. 1 is the perspective view of welding gun head of plastic spiral pipe of the present invention;
Fig. 2 be among the present invention cavity look closely structural representation;
Fig. 3 is that cavity among the present invention is along the vertical sectional structure sketch map of the direction of length;
Fig. 4 is the structural representation of another embodiment of the present invention;
Fig. 5 is an applying examples of the present invention.
The specific embodiment
Referring to Fig. 1, Fig. 2, Fig. 3, welding gun head of plastic spiral pipe of the present invention 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.
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 among the present invention and the two end plates 2.
Welding gun head of plastic spiral pipe of the present invention is used for through the fusion welding rod plastic spiral pipe and injection moulding bell and spigot pipe fitting being welded to connect, and its applying examples is as shown in Figure 5, and shown in the figure, 3 is plastic spiral pipe, and 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 welding gun head of plastic spiral pipe of the present invention to be; The fusion welding rod that extruder is extruded gets into cavity 1 by charging hole 11; Get into 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 gets into 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.
