With being fitted in mounting shell 1 for two the first guide grooves 24.
As shown in figure 16, above-mentioned trigger mechanism 8 include triggering block 42, triggering shell 43, triggering spring 44, the second guide block 45,
4th guide groove 46, triggering slot 47, wherein as shown in figure 18, triggering on shell 43 has triggering slot 47, on the two sides for triggering slot 47
It symmetrically opens there are two the 4th guide groove 46, driving shell 53 is mounted on mounting shell 1 by fixed support 41;As shown in figure 17, it touches
The upside for sending out block 42 has inclined-plane, and symmetrically there are two the second guide blocks 45 for installation on the two sides of triggering block 42, as shown in figure 16,
Triggering block 42 is fitted on triggering shell 43 by two the second guide blocks 45 and two the 4th guide grooves 46, and triggering block 42 and
It triggers and triggering spring 44 is installed between the bottom side of slot 47.
As shown in Figure 10, the both ends of above-mentioned threaded rod 18 are equipped with limit disk 33;The action type of limit disk 33 prevents
Actuating arm 4 skids off threaded rod 18.
Specific workflow: when the plastics pipe welding machine designed using the present invention, pass through two actuating arms 4 when in use
Two section plastic tubes are fixed, first control driving swing rod 10 is swung up, so that on 7 drive block 50 of driving mechanism and hot melt block 3
Driving plate 49 cooperates;Then control driving swing rod 10 drives swing rod 10 to will drive two oscillating rods 9 and swings to lower swing, and two
The swing of oscillating rod 9 just will drive 20 slide downward of sliding block connected to it, and sliding block 20 moves down will be by driving spring 19
Driving mechanism 7 is driven to move down;Driving mechanism 7 is moved down by the driving hot melt block 3 of drive block 50;When driving mechanism 7 is driven
Dynamic hot melt block 3 moves down the teeth so that heat block 3 and when limit plate 5 contacts, in second gear 23 with first gear 22 just
Good engagement, later, driving swing rod 10 continue on the one hand to drive swing rod 10 that will stretch through drive rod and sliding block 20 to lower swing
Driving spring 19;On the other hand controlling second gear 23 by driving swing rod 10 makes second gear 23 drive 22 turns of first gear
Dynamic, first gear 22 drives threaded rod 18 to rotate, and threaded rod 18, which rotates, will to pass through 4 edge of actuating arm being threadedly engaged with it
Threaded rod 18 axis it is mobile;It is heated so that two plastic tubes are contacted with hot melt block 3, after plastic tube heating, control
Drive 10 backswing of swing rod, drive swing rod 10 in initial reverse swing process, driving swing rod 10 can by second gear 23,
First gear 22 drive threaded rod 18 rotate backward, threaded rod 18 rotate backward will make actuating arm 4 drive plastic tube along
Threaded rod 18 is mobile to two sides;Swing rod 10 is driven to swing meeting simultaneously so that driving spring 19 is stretched partially gradually resets, when the
After teeth and first gear 22 on two gears 23 disengage, actuating arm 4 is restored to initial position, and driving spring 19 is restored to freedom
Retracted position drives swing rod 10 to continue to swing and hot melt block 3 will be pushed to move up by sliding block 20 and driving spring 19 at this time;
During driving mechanism 7 moves up, triggering block in the upper side and trigger mechanism 8 of the drive block 50 in driving mechanism 7
After 42 downside face contact, triggering block 42 will squeeze the inclined-plane of 50 upper side of drive block, so that drive block 50 is to far from touching out
The side for sending out block 42 is mobile, and after triggering block 42 is disengaged with drive block 50 completely, drive block 50 will be in corresponding return spring 51
Under the action of remove again;When driving mechanism 7 is during moving up, before triggering block 42 is disengaged with drive block 50 completely,
Drive block 50 can be disengaged first with the driving plate 49 being mounted on hot melt block 3, be drawn since in this state, driving spring 19 is in
State is stretched, so hot melt block 3 will be moved up quickly and be returned to original state;And then secondary control driving swing rod 10 is downward
It swings, drives plastic tube mobile by driving 10 weave control of swing rod, two actuating arms 4, finally contact pressure for two plastic tubes
Weld together;To reduce because manually influencing welding effect because nozzle cannot be aligned to two plastic tube pressures,
Welding is caused leak occur;It is prevented when using the heating plate that can only carry out unilateral heating simultaneously, two plastic tubes cannot be same
Shi Jinhang heating, in this state, in butt welding, one of them in two plastic tubes can heat first, after the completion of heating,
During heating to another plastic tube, if overlong time, the plastic tube originally heated just will appear solidification phenomenon,
Lead to weld failure.
