Further, the plastic granulator raw material mixture is to synchronize each component of plastic granulator raw material in proportion to be added to hot mix
In machine, after the mixed machine high-speed stirred mixing temperature of overheat reaches 95~115 DEG C, the material mixed is put into cold mixer, it is low
Speed mixing is cooled to 65~85 DEG C of progress transition granulations up to material temperature, is drawn onto the mixed material mixed using suction feeder
Granulating extruder feed hopper, uniformly mixed raw material is inputted through hopper in the machine barrel of extruder, with the rotation of screw rod, raw material quilt
Auger pressure push head to, due to having filter screen, flow distribution plate and the resistance of mold before machine barrel, along with the volume between screw thread by
Gradual change is small, and the raw material to be advanced by auger is subject to large compressive, while the raw material heating by machine barrel again, and raw material is by crowded
When pressure, shearing, stirring action and the friction between machine barrel, spiral shell and the friction between raw molecule, certain heat can be all generated, therefore
Temperature of the raw material in machine barrel is higher and higher, and physical state is also gradually transformed into elastomeric state, finally becomes viscous state, until complete
The plastic cement of overall plasticization, viscous state is divided into two-way and is extruded into noodles by left blow tank and right blow tank by plastic band distribution mould
Then shape is cut into graininess by the synchronous high-speed rotating cutter of pellet device, then direct by cooling blower and wind conveying pipe

Tube body cooling device is designed to the combination of alignment cooling bath, transition cooling bath and terminal cooling bath, respectively to crowded
It is cooling that the pipe of extrusion successively carries out shaping and three-level, and alignment cooling bath, transition cooling bath and terminal cooling bath successively straight line
Distribution, wherein alignment cooling bath, transition cooling bath and terminal cooling bath are back and forth to meet back calandria cooling bath, and alignment is cooling
The shaping casement accommodated to shaping pipe is formed after shaping arc groove docking in slot on upper alignment wheel and lower alignment wheel, in sink
It is middle that the shaping roller group being made of upper alignment wheel and lower alignment wheel is equipped with along straight line, annular is formed by deflecting roller after tube body shaping
The reciprocal cooling path of annular, which is realized, solidifies the primary cooling of shaping tube body, then is transferred to transition cooling bath and terminal cooling bath,
It is again provided with the train group being made of deflecting roller in transition cooling bath and terminal cooling bath and holding wheel, tube body to be cooled pass through wheel
It is that group forms reciprocating circular cooling tube body group, the overall length of tube body cooling bath can be greatly shortened in this way, reduce workshop and account for
Use area.
This programme is used through Experimental Comparison, the crowded pipe speed of the tube extruding machine is three times of conventional tube extruding machine, same production capacity
Power consumption can reduce by 27%~30%, the overall length of cooling trough does not increase anti-drop, the cooling water flute length of existing tube extruding machine
Degree is 20 meters, if squeezing pipe speed improves 3 times, by existing cool down criteria requirement, the length of cooling trough should reach 60 meters, and originally
The overall length of cooling trough only has 12 meters in invention, this just greatly reduces crowded pipe and produces occupied plant area, reduces investment,
This mainly has benefited from applicant and improves the structure of cooling trough, and cooling trough is divided into alignment cooling bath, mistake in the present invention
Cross cooling bath and terminal cooling bath, and shaping water-cooling groove, transition cooling bath and terminal cooling bath are that back and forth to meet back calandria cold
But slot uses the present invention program, although squeezing Guan Su improves three times, the total length of three groups of cooling troughs is only 12 meters, due to
It is all provided with the tube body being made of deflecting roller in cooling troughs at different levels back and forth around train, tube body to be cooled is made by train group
It is formed around train group compound around cooling tube body group, although the length of cooling trough in this way shortens, the cooling overall length of tube body
Degree reaches 60 meters, thus can be shortened the overall length of tube body cooling bath, reduces the workshop area occupied of cooling trough.

4. special according to claim 3 by the method for plastic granulator machine and tube extruding machine series connection high efficiency production energy-saving plastic pipe
Sign is: the plastic granulator raw material mixture is to synchronize each component of plastic granulator raw material in proportion to be added in the mixed machine of heat, is passed through
After the mixed machine high-speed stirred mixing temperature of heat reaches 95~115 DEG C, the material mixed is put into cold mixer, mixed on low speed until
Material temperature is cooled to 65~85 DEG C of progress transition granulations, and the mixed material mixed is drawn onto granulating extruder using suction feeder
Feed hopper, uniformly mixed raw material is inputted through hopper in the machine barrel of extruder, and with the rotation of screw rod, raw material is pushed away by auger pressure
To head, due to having filter screen, flow distribution plate and the resistance of mold before machine barrel, along with the volume between screw thread gradually becomes smaller, quilt
The raw material that auger advances is subject to large compressive, while raw material heating by machine barrel again, raw material is squeezed, shears,
The friction between friction and raw molecule when stirring action between machine barrel, spiral shell, can all generate certain heat, therefore raw material is in machine
Temperature in cylinder is higher and higher, and physical state is also gradually transformed into elastomeric state, finally becomes viscous state, until being plasticized completely,
The plastic cement of viscous state is divided into two-way by plastic band distribution mould (2) and is extruded by left blow tank (27) and right blow tank (28)
Then noodle shape is cut into graininess by synchronous pellet device (3) high-speed rotating cutter, then by cooling blower (5) and
Wind conveying pipe (51), which is directly blown into tube extruding machine (6) hopper on both sides, starts to squeeze pipe processing, is solidified by the appearance of pelletizer output
Internal still hot PVC transition particle is sent into the machine barrel of tube extruding machine (6) by wind conveying pipe (51), and PVC transition particle passes through second
Heating and screw extruding are quickly plasticized again, then squeeze out specific standard plastic cement pipe by molding die, and pipe passes through tube body
Cooling device (7) shaping, multistage cooling and solidifying molding, obtain predetermined plastic tube body.
