It is identical as the quantity of each group plastic tube.
By using above-mentioned technical proposal: at the beginning of feeding, it is only necessary to by manually by plastic tube (such as: φ 16*1.5
Model) it is placed on conveying assembly, by the conveying one by one of conveying assembly, plastic tube can successively be heated (in preheating group
In part) and extrusion forming (in thread forming component), without repeatedly accurate feeding and time-consuming feeding, and then improve pair
The shaping efficiency of plastics pipe interface external thread；
In more detail:
1. the working principle (such as FIG. 1 to FIG. 3) of conveying assembly:
Firstly, plastic tube being placed between adjacent positioning plate or being placed on material storing box, drawn by drive module
It will drive the positioning plate activity on driving chain while dynamic driving chain movement, to drive the plastics between positioning plate
Pipe activity；The working principle of drive module: motor drives drive block rotation, since the shape of drive block is set as " sector ", and
When drive block is rotated around motor output shaft, the articulated shaft being fixedly connected on drive block will drive around motor output shaft public affairs
Turn, due to being rotatably connected to pull rod on articulated shaft, the one end that will drive pull rod is swung in " circumferential ", finally, can band
Hook type block on dynamic pull rod free end is caught in the chain link of driving chain, and it is mobile to pull driving chain, and then passes through positioning
Strip moves plastic tube movement, can be roughly divided into two states: first, driving status, it may be assumed that hook type portion is in chain link and draws
Dynamic driving chain is mobile；Second, preparing state: i.e.: drive block enters hook type portion in next chain link in drive pull rod
Segment；
2. the effect (such as Fig. 3 and Fig. 7) of preheating assembly:
When positioning plate drives plastic tube mobile, initially enters in preheating assembly and heated, it may be assumed that one end of plastic tube
It is moved in the pre- heat channel of preheating table, while mobile, external air is pumped into hot air pipe and passes through heater by blower
To the air heating in hot air pipe, hot gas (or hot wind) is made, when hot gas enters in pre- heat channel, with plastic tube
Interface contact, so that slight softening occurs for the interface of plastic tube, convenient for the molding of subsequent screw thread；
3. the working principle (such as Fig. 3~Fig. 6) of thread forming component:
By the plastic tube that preheating assembly heats, pass through its extruding slot for entering mold under thread forming of the guidance of pre- heat channel
Interior (mold and the setting of thread forming upper mold interval under thread forming at this time), after plastic tube is completely into squeezing in slot, this
When, since drive module is in " preparing state ", driving chain stops moving at this time, therefore plastic tube also stop motion, at this point, gas
Cylinder (can be controlled by PLC) driving thread forming upper mold contacts with mold under thread forming and clamps plastic tube, and
Motor (can be controlled by PLC) drive cam shaft rotation, and by drive shaft and squeeze outer shaft drive squeeze inner shaft slowly into
The one end for entering plastic tube, the variation of the diameter of axle due to squeezing inner shaft can make the one of plastic tube when it is in entrance plastic tube
End expansion, and interaction force is contacted and generates with the mold outside threads squeezed in slot, so that the end in plastic tube is formed
External screw thread；It should be understood that due to the thickness change of camshaft overhead cam, it, can interval promotion driving in cam axle
Axis, when the cam on camshaft does not push drive shaft, reset spring may make drive shaft to reset, so that one end of drive shaft is begun
It is contacted eventually with the side of cam, the normal operation of component so that guarantee is extruded to shape；
After the molding of plastic tube external screw thread, drive module is in " driving status ", so that next group of plastic tube be sent
Enter and carries out screw thread moulding in thread forming component；
It should be understood that plastic tube from preheating assembly is transferred on thread forming component disengaging conveying group in order to prevent
Part is equipped with positioning mainboard in the top gap of positioning plate, can effectively place plastic tube disengaging；
Through counting, one equipment of this hot extrusion molding machine can process 1800 siphon pipes per hour, wherein a people can be with
3 equipment are controlled simultaneously；Again because the present invention is before extrusion forming, first there is axial compression to increase at plastic tube thread forming heating position
Therefore thickness effect in processing, can use relatively thin tubing instead of traditional way, such as: with the pipe of existing φ 16*1.5
For material, this equipment can by using with a thickness of 1.2mm tubular object extruding at hickey with a thickness of the tubing of 1.5mm, therefore
It can largely save material.
Embodiment 2, with embodiment 1 the difference is that
As shown in figure 8, further including for being spaced the limitation movable limit of driving chain 41 in the specific embodiment of the invention
Device 5；The limiting device 5 includes driving and being spaced to be caught in the internal limit of driving chain 40 (that is: chain link) by cylinder 50
Block 51.
By using above-mentioned technical proposal: in plastic tube, just in moulding, (that is: one end of plastic tube is in thread forming component
It is interior), driving chain is mobile (such as: due to equipment fault) in order to prevent, and the chain of driving chain can be caught in by limited block
In ring, to can reach the effect to driving chain limit, guarantee the efficiency of production.
Embodiment 3, with above-described embodiment the difference is that
Such as Fig. 9, one layer is equipped in the specific embodiment of the invention, in the slot bottom of the pre- heat channel 300 for transmitting hot wind
322 internal heat of pipe to joint for plastic tube heat transfer plate 6.
In the specific embodiment of the invention, the thickness of the heat transfer plate 6 can gradually thicken from the conveying direction of conveying assembly.
Can be equipped in the specific embodiment of the invention, on the heat transfer plate 6 from conveying assembly direction through heat transfer plate 6 and
Hot air discharge channel 60 is connected to hot air pipe 322.
By using above-mentioned technical proposal: heat transfer plate can not only guarantee that the connector of plastic tube was softened because heated, but also can
Plastic tube is blown to avoid due to hot wind excessive heat, causes subsequent plastic tube installation not in place, influences externally threaded molding effect；
And the variation for the plate thickness that conducts heat can arrange forming plastic pipe end, be further ensured that the externally threaded molding effect of joint for plastic tube.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Within mind and principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
