At the position for stating locating slot 22, screw rod end passes freely through 22 rear thread of locating slot and connects and tense the sliding block 21, into
And position of the baffle 20 in the rack 1 is fixed.
When plastic tube is truncated, it is necessary first to according to the specification regulation position limiting mechanism of plastic tube, make position-limit mechanism
On connecting screw 16 between formed for plastic tube 5 across guide rail be aligned with the center two blades 4,
I.e. plastic tube is axial in truncation is aligned with the center between two blades 4, and concrete operations are as follows:
Most start to unscrew binding nut 23, enables connecting screw 16 to slide along regulating tank 17, on the one hand to pass through phase
Pair two connecting screws 16 limitation 5 transverse direction of plastic tube on movement；On the other hand lower clamp plate 13 and upper clamp plate 14 are existed
It is slided on vertical direction, it is to limit the movement on 5 vertical direction of plastic tube by lower clamp plate 13 and upper clamp plate 14, i.e., opposite
Two connecting screws 16 position corresponding with lower clamp plate 13 and upper clamp plate 14 forms guide rail (such as Fig. 7 of former and later two frame-shaped
It is shown).By the position of the slidable adjustment connecting screw 16 in regulating tank 17, and simultaneously by the with screw 19 in lifting groove 18
The position of interior up and down adjustment studdle 15 finally makes the centre bit between the longitudinal centre line of guide rail and two blades 4
Set alignment, the upper and lower sides of plastic tube 5 respectively can close in guide rail upper clamp plate 14 and lower clamp plate 13 slide, it is preferred: to lead
It is greater than 5 outer diameter 0.5-3mm of plastic tube to the upper-lower height of track, when meeting the requirement of above-mentioned size, one side plastic tube 5 can led
It is slided into track；It is axial inclined with the longitudinal centre line of guide rail after another aspect plastic tube 5 is directed to tracks positioned
Difference is negligible.Plastic tube 5 be sent between lower clamp plate 13 and upper clamp plate 14 and sequentially pass through the guide rail of former and later two frame-shaped with
Complete positioning.After plastic tube 5 is completed to position, axial to be overlapped with the longitudinal centre line of guide rail, also just reaching makes to mould
The purpose that expects pipe is axially aligned with the center between two blades 4.
After completing above-mentioned adjusting, further according to the position for needing the size being truncated to carry out controllable register 20: loosen the second screw 24,
Along sliding slot sliding slider 21 and baffle 20, the distance according to the scale on board 1 come the place's of identification baffle 20 apart from blade 4 is
Cut down the length of plastic tube 5, baffle 20, which slides into behind corresponding position, locks the second screw 24 and can consolidate the position of baffle 20
It is fixed.So far, adjusting work terminates, and can be sent into plastic tube 5 and start that work is truncated, the plastic tube 5 of feeding sequentially passes through front and back two
The guide rail of a frame-shaped, and baffle 20 is resisted after between two blades 4 to complete to position.After plastic tube 5 completes positioning, cylinder
7 telescopic end pulls two sector gears 8 to rotate simultaneously by connecting rod 10, and two sector gears 8 pass sequentially through shaft after rotating
9, the plastic tube 5 that swing arm 11 and section bar 12 drive two blades, about 4 relative motion to be truncated between two blades 4.Due to
Two sector gears 8 can synchronize under the driving of cylinder 7 relatively rotates same angle, therefore two blades 4 can also synchronize therewith
The same amplitude of upper and lower relative motion, i.e., it is consistent in section pipe depth of two blades 4, to can guarantee that two blades 4 are perpendicular in plastic tube 5
The center in section is docked, and avoids two blades, 4 docking location from being in 5 vertical section center of plastic tube amesiality and plastics occur
The phenomenon that cross section deformation of pipe.
The foregoing is merely presently preferred embodiments of the present invention, is not intended to limit the invention, it is all in spirit of the invention and
Within principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
