Disintegrating machine mainly carries out crushing operation to all types of plastic, can produce according to user's requirement the plastic pellet of variable grain size, and disintegrating machine is widely used in the fields such as plastic products, household electrical appliance, small household appliances, engineering plastics industry, plastics recovery.The rotor arrangement major part of disintegrating machine is formed by the rotor assembling of multiple points of profiles of tooth at present, and the area of tool assembly is little, and the set-up time is long, and the precision of assembling is also poor, and disintegrating machine operation is uneven, affects the life-span of disintegrating machine when serious.
Utility model content
In view of current, for the rotor arrangement above shortcomings of disintegrating machine, the utility model provides the rotor arrangement for disintegrating machine that a kind of area of tool assembly precision large, assembling is high, move balance.
For achieving the above object, embodiment of the present utility model adopts following technical scheme:
A kind of rotor arrangement for disintegrating machine, comprise main shaft, fixed block and rotor, described rotor is connected with main shaft by fixed block, the integrated welding of described rotor forms, rotor is connected with main shaft by multiple fixed blocks, the top of described rotor is provided with cutter, and described cutter is divided into multiple edges of a knife, and described multiple edges of a knife are arranged on cutter symmetrically.
According to an aspect of the present utility model, described cutter is divided into two edges of a knife, and the size of the outer end wall thickness of described each edge of a knife is large, and the size of middle wall thickness is little.
According to an aspect of the present utility model, the cross sectional shape of the described edge of a knife is right-angled trapezium.
According to an aspect of the present utility model, the flank of tool that the described edge of a knife is corresponding is provided with multiple cutting edges, and the top of described cutting edge is not higher than the top of cutter.
According to an aspect of the present utility model, described cutting edge is by bolt or be weldingly fixed on the flank of tool.
According to an aspect of the present utility model, the bottom of described rotor is provided with groove, in described groove, is provided with hole, and described rotor is connected with fixed block by hole.
According to an aspect of the present utility model, the two ends of described rotor are provided with locating hole.
According to an aspect of the present utility model, the width of described fixed block is 2-20 ㎝, and the distance between described fixed block is adjacent is 5-30 ㎝.
The advantage that the utility model is implemented: because the integrated welding of rotor of the present utility model forms, rotor is connected with main shaft by multiple fixed blocks, the top of rotor is provided with cutter, cutter is divided into multiple edges of a knife, multiple edges of a knife are arranged on cutter symmetrically, and therefore high, the operation balance of the area of the tool assembly of rotor arrangement of the present utility model precision large, assembling, set-up time are short.
Brief description of the drawings
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, to the accompanying drawing of required use in embodiment be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the schematic diagram of a kind of rotor arrangement for disintegrating machine described in the utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, a kind of rotor arrangement for disintegrating machine, comprise main shaft 1, fixed block 2 and rotor 7, rotor 7 is connected with main shaft 1 by fixed block 2, the integrated welding of described rotor 7 forms, and rotor 7 is connected with main shaft 1 by multiple fixed blocks 2, and the top of rotor 7 is provided with cutter 9, cutter 9 is divided into multiple edges of a knife 6, and multiple edges of a knife 6 are arranged on cutter 9 symmetrically.
In actual applications, cutter 9 is divided into two edges of a knife 6, and the size of the outer end wall thickness of each edge of a knife 6 is large, and the size of middle wall thickness is little, and the cross sectional shape of the edge of a knife 6 is right-angled trapezium, can be also other shape, such as isosceles trapezoid etc.In addition, cutter 9 also can be divided into three edges of a knife 6, such as the cross sectional shape of the middle edge of a knife 6 is rectangle, the cross sectional shape of the edge of a knife 6 on both sides is right-angled trapezium, only needs to ensure that multiple edges of a knife 6 are arranged on cutter 9 symmetrically, like this in the time of mounting cutter 9, the area assembling due to cutter 9 is large, so the speed that rotor 7 is installed is fast, the precision of assembling is also high, ensures also disintegrating machine operation balance.
In actual applications, cutter 9 sides of the edge of a knife 6 correspondences are provided with multiple cutting edges 8, the top of cutting edge 8 is not higher than the top of cutter 9, cutting edge 8 is by bolt or be weldingly fixed on cutter 9 sides, the cutting edge 8 of the present embodiment is fixed on cutter 9 sides by screw thread, cutter 9 sides of the each edge of a knife 6 correspondences are provided with four cutting edges 8, and the distance between adjacent two cutting edges 8 equates.
In actual applications, the bottom of rotor 7 is provided with groove 4, is provided with hole 3 in groove 4, and rotor 7 is connected with fixed block 2 by hole 3, and for easy for installation, hole 3 adopts screwed hole, and rotor 7 is connected with fixed block 2 by bolt.
In addition, the width of fixed block 2 is 2-20 ㎝, and the distance between fixed block 2 is adjacent is 5-30 ㎝, and the two ends of rotor 7 are provided with locating hole 5, the lifting when location while facilitating rotor arrangement to install and maintenance, replacing.
The above; it is only detailed description of the invention of the present utility model; but protection domain of the present utility model is not limited to this; the technical staff of any skilled is in the disclosed technical scope of the utility model; the variation that can expect easily or replacement, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of described claim.
