The present invention has the advantages that 1. double screw extruder power control cabinets are independently arranged, all on lines use Quick connector.
Double feeding designs can ensure the health of operator without artificial filling parking material.Vacuum line design: pipeline arrangement side
Just the buildup in pipeline is cleared up, keeps pipeline unimpeded, production efficiency improves.The double-wall corrugated pipe bore produced is bigger, is applicable in
Range is wider.
2. squeezing out head inner wall runner and outer wall runner being stablized, the inner and outer wall of double-wall corrugated pipe is not likely to produce bubble.
The ring stiffness of double-wall corrugated pipe enhances.Mechanical disorder is reduced, and improves production efficiency.
There is respective servo motor to drive 3. molding machine module drives upside down respectively, facilitates adjustment gear phase, eliminate
Gear phase trouble is manually adjusted, while driving link few, transmission cumulative errors reduce, and transmission accuracy is improved.
Conjunction divides mould inserted block structure to improve, and mechanical disorder is reduced, and improves production efficiency.Former inserted block moves up and down unilateral stress, unbalance stress
Even that cylinder is caused to run incomplete phenomena sometimes, machine just will call the police, and exit operating position, and production line is caused to suspend, and release report
It is alert, trombone slide could be continued.The above problem is solved by the production line.It is ball wire that workbench, which is moved forward and backward driving form,
Thick stick+linear guide, coefficient of friction is small, and transmission effect is high, and guiding accuracy is high.It is ball-screw that workbench, which moves left and right driving form,
Ball-screw-transmission coefficient of friction is small, and feed screw nut gap is small, is conducive to die gap adjustment.
4. it is that a mountain one is flat that cutting machine coaster, which is moved forward and backward guide rail, compared to common rectangular guideway, linearity is good, gapless,
Advantageous cutting.Cutter clamp can be adjusted with respect to cutter holder housing shaft angle by gear and adjusting tooth, not have to unclamp toolholder bodies, side
Adjustment, and adjust angular dimension have foundation.Walking is variable-frequency motor driving before and after cutting coaster, can be driven with molding machine
Module movement speed is synchronous.Tubing is cut off by high-speed steel blade, noiseless and chip.Tubing wave crest fluctuates travel switch and counts hair
It enables, it is accurate.
5. pipe-expanding machine first preheats before being flared to tube body, flaring efficiency is improved.Setting in front of the heating furnace of pipe-expanding machine
Cutting means enclosure, prevents heat loss, has saved the energy, also improve flaring efficiency.The adjustment mechanism up and down of heating furnace can be adjusted
Homogeneous tube body height, so that the tube body for being suitable for different-diameter is flared, the scope of application is wider.It is flared frame and is furnished with cooling device,
So that flaring is more perfect, it is more advantageous to the connection of tube body.The conveying device delivery pipe body of pipe-expanding machine is more efficient, and conveying device
Adjustable height can be adapted for the tube body flaring of different tube diameters.
6. mold width becomes smaller, can be used interchangeably with adapted module on the molding machine of various models, molding machine main motion
Apart from short, advantageous Die Design, the short melt pressure of machine barrel is easy to control, and trombone slide speed is fast, also reduces for centre distance workbench front end
Manufacturing cost.PVC-U pipe molds and divides mould strength ratio HDPE pipe big, inlays wear-resisting key in module end face, prevent module molding with
Divide mould Shi Lamao.Outer gas pressure ratio PE is big when PVC-U pipe forms, and rack gear clamping plate chucking power is big, the easy plucking in the rack gear back side, to solve
This problem tumbles in Quenching Sheet in rack gear back.It is vacuumized for the waveform of major diameter PVC-U pipe, 1 seam 1 is taken to take out, pumping speed
Rate improves, and tubing shape is fuller.
