Abstract
The utility model relates to a rotary cutter for a plastic pulverizer, comprising a plurality of cutter blocks connected in series. The cutter blocks are composed of cutter bodies and cutter heads. The cutter heads made of high-quality metal material are connected with the cutter bodies via screws. The cutter edges of the cutter heads are parallel to a rotating axial line. The cutter heads of adjacent cutter blocks differ in definite angles in turn on the outer cylindrical surface of the rotary cutter, and three cutting edges forming a step shape approximating to a spiral line. The cutter of the utility model overcomes the disadvantage that a composite inclined cutter has nonuniform stress, large resistance and axial force in the process of cutting, and the rotary cutter for a plastic pulverizer has the advantages of sharp cutting edges, strong capability of crushing thick objects, and the cutter heads can be detached singly for sharpening or replacement after abrasion.
Description
The utility model is a kind of plastic cement Material disintegrator rotary cutter.
Plastic cement Material disintegrator rotary cutter commonly used is a kind of combined inclined cutter, and this combined type inclined cutter is to be formed by screw attachment by the cutter hub of an integral body and several blades.Knife face and cutting edge are inclined to certain angle with respect to rotation in the planar shaped of blade.There are three shortcomings in this cutter:
1. produce very big axial force when cutting material.
2. material is concentrated to a side vertically when working, and makes the cutter discontinuity.
3. cutting resistance is very big.
It is little that the purpose of this utility model provides a kind of cutting resistance, and cutter is stressed evenly, do not produce the plastic cement Material disintegrator rotary cutter of axial force during the cutting material.
The characteristics of the utility model cutter are:
Rotary cutter is to be made by the combined cutter piece series connection of several bikinis; Each cutter piece is made up of cutter head and cutter hub; Cutter head is made with the high-test metal material, is fixed on the cutter hub by screw; Blade on the cutter head is parallel to rotation.
By two key connecting, the keyway that is connected on each the cutter piece on the main shaft differs certain angle successively between cutter piece and the main shaft, so the blade of each cutter head forms the cutting edge that three steps are similar to helix on the cylinder of the outer garden of rotary cutter.
Because the utility model cutter structurally has These characteristics, to have a blade sharp so it is compared with combined inclined cutter commonly used, cutting resistance is little, the thickness of comminuting matter is big, cutter is stressed evenly, vibrate little, noise is low, does not have axial force during cutting, can pull down sharpening or replacing behind any one tool bit abrasion separately and needn't change advantages such as cutter hub.
The structure of cutter piece and rotary cutter as shown in Figure 1 and Figure 2.
Number in the figure is represented respectively:
1 cutter hub, 2 cutter heads, 3 soket head cap screws, 4 main shafts, 5 round nuts, 6 rotary cutters, 7 rotating circular disks.
The broken machine structure of plastic cement of using the utility model cutter is as shown in Figure 3, Figure 4:
This plastic cement Material disintegrator is made up of base (8), lower support (9), flange (10), upper frame (11), the L shaped flange of hopper (12) (13), flywheel (14), main shaft (15), big belt pulley (16), belt (17), small belt pulley (18), motor (19), rotary cutter (20), fixed blade parts such as (21).Rotary cutter is positioned in the inner chamber of upper frame and lower support formation, with the cutting that is fixed on the adjustable fixed blade formation comminuting matter on the upper frame power of motor is done and passed to main shaft by small belt pulley, belt, big belt, the motion of comminuting matter is finished in the rotation of driven rotary cutter.
Compare this novel Material disintegrator as can be known except the advantage with above-mentioned rotary cutter with this Material disintegrator and other Material disintegrator, also have simple in structure easy to usely, pulverize to render a service that the low cleaning of high production cost is convenient can change rapidly the advantage that other Material disintegrator such as comminuting matter kind does not possess.
Claims (1)
- A kind of plastic cement Material disintegrator rotary cutter is characterized in that rotary cutter is to be in series by several cutter pieces; Each cutter piece is to be made of a cutter hub and several cutter heads; Cutter head by screw attachment on the flute profile table top on the cutter hub circumference, the blade of cutter head is parallel to rotation, and the cutter piece connects with main shaft by two keys, on the external cylindrical surface of rotary cutter, adjacent each cutter piece cutter head differs certain angle successively, constitutes the cutting edge of the approximate helix of step.
