Part 5.
The operation principle of the present embodiment is:
Put tubing into loading plate 1, tubing is slipped down at barb 103 by hopper 101 into guide rack 102, cylinder drives
The dynamic material block 201 that pulls out is rotated, and makes the bearing groove for pulling out material block 201 drive tubing to leave the retainer that guide rack 102 turns to feeding material component 3
In the feeding groove of plate 301, motor drives crank block 305 to rotate one and encloses, so as to drive the delivery sheet 302 of feeding material component 3 to do arc
Shape is moved, and tubing is held up from feeding groove, and be transported in another adjacent feeding groove.Until retainer plate 301
When being equipped with tubing in several feeding grooves, delivery sheet 302 tries again arcuate movement, a tubing can be sent into retainer group
In the retainer groove 411 of the reducing pallet 401 of part 4, while other several tubing can be held up toward moving in the feeding groove of sky.This
When, pull out material block 201 and continue to be sent in the feeding groove of retainer plate from the extraction tubing of loading plate 1.Tubing is reached on retainer component 4
When, tubing is clamped in active roller 503 and return idler 504 by the Mobile base 502 for clamping feeding assembly 5 under the driving of cylinder
Groove in, then motor drive active roller 503 rotate so as to drive tubing to move into next process.
In the present embodiment, the loading plate 1 includes hopper 101 and is obliquely installed in the discharging opening of hopper 101
The guide rack 102 of lower section, one end of the guide rack 102 is provided with the barb 103 for stopping tubing.The guide rack 102 has
Constant slope, allows tubing to be slided along guide rack 102 under the inertia of deadweight, and the barb 103 of guide rack 102 effectively stops tubing
Skid off guide rack 102.It is this simple structure, compact, manufacturing cost can be effectively reduced.
In the present embodiment, the material component 2 that pulls out includes the first rotating shaft support base 202, the peace that are used to fix first rotating shaft 203
