Detailed description of the invention
See Fig. 1, Fig. 2 and Fig. 2 a, the form of structure that electronic finisher in the present embodiment smears dish speed adjusting gear is: in arrangements for speed regulation, the rotation of drive motors 1 exports the transmission of band drive mechanism, after reductor 2 again through having fixing speed reducing ratio slows down, smear dish 10 by speed reducer output shaft drive to rotate, the size of the effective diameter of the driving pulley 8a in the V belt translation structure utilizing speed adjusting lever 4 adjustment to be arranged between motor 1 and reductor 2 realizes smearing the speed governing of dish 10, V belt translation structure is by the driving pulley 8a of the output shaft end being fixedly installed on motor 1, the driven pulley 9 and the driving belt 11 that are fixedly installed on the output shaft end of reductor 2 are formed.
As shown in Figure 1, on reductor 2, longitudinal rail 3 is fixedly installed in the present embodiment, motor 1 can guide rail 3 slippage along the longitudinal, be connected with wire rope 5 between motor 1 with speed adjusting lever 4, return spring 7 is provided with between motor 1 and frame 6, speed adjusting lever 4 pulls motor drive direction contrary with the force direction of return spring 7 on motor 1, pull speed adjusting lever 4 can change distance between driving pulley 8a and driven pulley 9, the section arranging driving belt 11 is trapezoidal, relative set is wedge shape anchor ring for the belt grooves of setting-in driving belt 11 on driving pulley 8a, the difference being in wedge shape anchor ring with driving belt 11 circumferentially makes driving pulley 8a obtain the effective drive diameter of different driving wheels.
As shown in figures 2 and 2 a, arrange clutch 8 in the present embodiment, clutch 8 comprises and to be in clutch platen 8b on coaxial position and conical centrifuge block 8c with driving pulley 8a; It is trapezoidal belt grooves that the clutch platen 8b that can move axially and driving pulley 8a forms section jointly, and the rear ends of clutch platen 8b is the taper surface be equipped with conical centrifuge block 8c; Conical centrifuge block 8c utilizes the driving of centrifugal force to be formed and moves radially, and promotes with its taper surface the clutch that clutch platen 8b forms axial displacement formation clutch platen 8b and driving pulley 8a.During electric motor starting, the conical centrifuge block 8c under the influence of centrifugal force in clutch 8 is formed and moves radially, and therefore extrudes clutch platen 8b to the skew of driving pulley 8a side, and tightening belt, export transmission.
As shown in Fig. 3 and Fig. 3 a, in the present embodiment, the form of structure of speed adjusting lever 4 is: form latch-up structure by the ratchet 4d be fixedly installed and the ratchet 4c that is meshed with ratchet 4d, both sides symmetrical on ratchet 4d, the radial direction of ratchet 4d is provided with rotating a pair handle bracket, handle 4a is fixedly installed on the top of a pair handle bracket 4f, the clutch 4b that argues for the sake of arguing is supported in the elongated hole of a pair handle bracket 4f, and can moving radially along ratchet 4d in elongated hole, spring pressure bar 4e connects firmly at the middle part of arguing for the sake of arguing 4b, and ratchet 4c connects firmly the top rod end at spring pressure bar 4e.During adjustment, the handle 4a that one hand is held with a firm grip on the speed adjusting lever 4 and 4b that argues for the sake of arguing, drives ratchet 4c by spring pressure bar 4e, makes ratchet 4c rise and be separated with ratchet 4d, now, pulls speed adjusting lever to appropriate location; Unclamp the 4b that argues for the sake of arguing again, under the compressing of spring pressure bar 4e, ratchet 4c return and ratchet 4d clamp and lock, and complete speed-regulating function, and the form of structure of this speed adjusting lever can keep count of according to the ratchet on ratchet and realize corresponding multi-change speed function.
Machine is under job state, when needs adjustment smear dish 10 its rotating speed is reduced time, pull speed adjusting lever 4 backward, motor 1 on sliding guides 3 slides backward, center to center distance L between driving pulley 8a and driven pulley 9 increases, belt 11 is wedged downwards along the belt grooves of active wheel belt, and effective drive diameter of driving pulley 8a reduces relatively, and adjustment is smeared the dish 10 i.e. rotating speed of cutterhead and thus reduced; When the rotating speed needing adjustment to smear dish 10 raises, discharge speed adjusting lever 4 forward, be subject to the effect of return spring 7 pulling force, motor 1 forward slip on guide rail 3, center to center distance L between driving pulley 8a and driven pulley 9 reduces, belt 11 raises up along the belt grooves of driving pulley, and the effective drive diameter of driving wheel increases relatively, and therefore the rotating speed smearing dish 10 raises.
