The specific embodiment
As Fig. 1-Figure 4 shows that cutterhead precise adjusting device of the present utility model, comprise cutter spindle 1, cutter spindle 1 is provided with drive unit and for the cutterhead of mounting cutter, wherein drive unit is the driving pulley 7 that is arranged on cutter spindle 1 axle head, driving pulley 7 is connected with drive motors by belt, cutter spindle 1 one end peripheries are rotatably connected to worm gear pivoted housing 3 by bearing 1, worm gear pivoted housing 3 peripheries are connected by guide thread 6 with support 4 endoporus, cutter spindle 1 other end and support 4 are rotationally connected by bearing 22, and the outer ring of bearing 22 and support 4 endoporus matched in clearance, be rotatablely equipped with the worm screw 9 with the engagement of the worm-gear toothing of worm gear pivoted housing 3 peripheries in support 4, worm screw 9 is provided with and stretches out the outer adjustable side of support 4, adjustable side is provided with the regulating handle 10 of being convenient to turn, its middle (center) bearing one can be selected angular contact ball bearing, and bearing two is selected cylinder roller bearing, also be provided with locking device in the support 4 of worm gear pivoted housing 3 peripheries, but this locking device comprise and the axial check lock lever 12 of vertical turn of worm gear pivoted housing 3, the locking end of check lock lever 12 against worm gear pivoted housing 3 peripheries for locking worm gear pivoted housing 3.Stretch out outside support 4 and be provided with the set lever 13 of being convenient to turn with the locking end other end in opposite directions of check lock lever 12; For ease of lubricated, be evenly equipped with some radial direction through hole on the middle part circumference of worm gear pivoted housing 3, this radial direction through hole is communicated with fuel tank 11, and the outer end of bearing 1 and bearing 22 is respectively equipped with outside framework oil seal 8.
Adjusting device of the present utility model, cutter spindle 1 is arranged on the discharge end of bulking machine by support 4, and can the coarse adjustment cutterhead in installation and the distance of material discharging mould, when need accurate adjustment cutterhead and discharge die of extruder plate apart from the time, only need hand rotation regulating handle 10, making worm screw 9 drive worm gear pivoted housing 3 rotates, worm gear pivoted housing 3 moves axially in support 4 holes along guide thread 6 in rotation process, and drive cutter spindle 1 synchronous shift realizes the adjusting of cutterhead and discharge die of extruder distance between plates, after the cutterhead positional precision is adjusted, turn set lever 13, make the locking end of check lock lever 12 prevent the unexpected rotation of worm gear pivoted housing 3 in the course of work and change cutter location with locking worm gear pivoted housing 3 against worm gear pivoted housing 3 peripheries.The displacement of the relative material discharging mould of cutterhead can be by the transmission parameter of worm and gear and the dimensional parameters accurate adjustment of guide thread.
The middle worm and gear of the present embodiment and guide thread parameter and degree of regulation calculate as follows:
Worm spiral lift angle Φ=8.13 °; Reference diameter of worm d=21mm; Reference circle of wormwheel diameter D=105mm, the screw thread of worm gear pivoted housing is M110 * 2;
The helical pitch T=d of worm screw * tan Φ=3mm
Be that worm screw often rotates a circle, worm screw drives worm gear and rotates 3mm;
The reference circle girth A=π D=329.7mm of worm gear;
Worm screw often rotates a circle, and the angle that the worm gear pivoted housing rotates is α:
α=3/329.7×360°=3.276°
The screw thread of worm gear pivoted housing is M110 * 2, and helical pitch is 2mm,
When the worm gear pivoted housing turns the α angle, the displacement L that the worm gear pivoted housing is axial:
L=3.276/360×2=0.02mm，
