Axle center with movable arbor is an initial point, and adjacent two formed angles of stationary knife plate are respectively 35 degree, 150 degree, 35 degree and 140 degree.
Ledger-plate is fixed on the stationary knife plate by fixed screw, between ledger-plate and fixed screw, be provided with a stationary knife pressing plate, one side of ledger-plate is provided with the top tool section, the bossing of this top tool section is stuck on the stationary knife plate in the corresponding grooves, the stationary knife pressing plate is pressed on ledger-plate and top tool section on the stationary knife plate, be provided with one in the tool section of top and adjust screw, adjust screw and pass the top tool section, the one end withstands on the ledger-plate.
Cutting blade is fixed on by fixed screw on the end of movable knife rack, is provided with a moving knife pressing plate between cutting blade and fixed screw, and one side is provided with screw base in the end, adjusts screw and passes this screw base, and the one end withstands on the cutting blade.
The beneficial effects of the utility model are: this machine is installed four cuttves that are ranked, and makes moving knife can carry out twice shearing to plastics when rotating a circle, thereby has improved the efficient of pulverizing plastics; And adopt the mode of symmetric design, make the machine stress equalization, process is more smooth and easy; By adjusting, can adjust the shearing inclination between cutting blade and the ledger-plate, thereby can cut into plastics the particle of various different sizes, to meet different requirements to adjusting screw.
Description of drawings
Fig. 1 is a structure chart of the present utility model.
Among the figure:
10 fixed screws, 20 adjust screw,
50 movable arbors, 60 movable knife racks,
70 stationary knife pedestals, 201 screw bases,
301 stationary knife pressing plates, 302 ledger-plates,
303 stationary knife plates, 304 top tool sections,
401 cutting blades, 402 moving knife pressing plates.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described:
Plastic crusher comprises cutting mechanism and the drive unit that drives cutting mechanism work.Cutting mechanism as shown in Figure 1 comprises stationary knife pedestal 70, movable arbor 50 and movable knife rack 60, and the middle part of stationary knife pedestal 70 is an open circles, is arranged with four stationary knife plates 303 at the two ends of circle, fixes a ledger-plate 302 on each stationary knife plate 303.Movable arbor 50 places open circles, and movable knife rack 60 is socketed on the movable arbor 50, and drive unit drives movable knife rack 60 by movable arbor 50 and rotates.Movable knife rack 60 is provided with three ends, and the equidistant each other equal angles in these three ends distributes, and fixes a cutting blade 401 on each end.
Axle center with movable arbor 50 is an initial point, and adjacent two stationary knife plates, 303 formed angles are respectively 35 degree, 150 degree, 35 degree and 140 degree.Adopt such arrangement mode, stress equalization when making machine shearing plastics, process is more smooth and easy, and charging and discharging are also than being easier to.
Described ledger-plate 302 is fixed on the stationary knife plate 303 by fixed screw 10, is provided with a stationary knife pressing plate 301 between ledger-plate 302 and fixed screw 10.The stationary knife pressing plate of setting up 301 can strengthen lifting surface area, and ledger-plate 302 is fixed on the stationary knife plate 303 more firmly.One side of ledger-plate 302 is provided with top tool section 304, the bossing of this top tool section 304 is stuck on the stationary knife plate 303 in the corresponding grooves, stationary knife pressing plate 301 is pressed on ledger-plate 302 and top tool section 304 on the stationary knife plate 303, because the effect that holds of bossing is shifted top tool section 304 stressed being not easy.Be provided with one in the top tool section 304 and adjust screw 20, adjust screw 20 and pass top tool section 304, the one end withstands on the ledger-plate 302, by adjusting adjustable angle of adjusting blade 302 to adjusting screw 20.
Described cutting blade 401 is fixed on the end of movable knife rack 60 by fixed screw 10, between cutting blade 401 and fixed screw 10, be provided with a moving knife pressing plate 402, the moving knife pressing plate of setting up 402 can strengthen lifting surface area, and cutting blade 401 is fixed on the end of movable knife rack 60 more firmly.One side is provided with screw base 201 in the end, adjusts screw 20 and passes this screw base 201, and the one end withstands on the cutting blade 401, by adjusting adjusting screw 20, can adjust the angle of cutting blade 401.
This machine is installed four cuttves that are ranked, and makes moving knife can carry out twice shearing to plastics when rotating a circle, thereby has improved the efficient of pulverizing plastics.By adjusting, can adjust the shearing inclination between cutting blade 401 and the ledger-plate 302, thereby can cut into plastics the particle of various different sizes, to meet different requirements to adjusting screw 20.
Certainly, above embodiment just is explanation rather than restriction the utility model, the above only is preferred embodiment of the present utility model, so all equivalences of being done according to the described method of the utility model patent claim change or modify, is included in the utility model patent claim.
