Abstract
The utility model relates to a kind of negative-pressure suction device of plastic granulator crushing knife box, includes that suction bucket, cylindrical shell, water conservancy diversion are stifled, compressed air inlet suction port; Described compressed air inlet suction port is arranged on the hole seat of cylinder lateral wall, suction bucket screws in the screw thread of cylindrical shell upper inside wall, the stair-stepping shaft shoulder of bucket pipe outer rim of suction bucket forms backflash mutually across a certain distance with the stair-stepping shaft shoulder in cylindrical shell hollow form top, the bucket pipe outer rim of suction bucket and the inwall of cylindrical shell hollow form leave gap, described water conservancy diversion is stifled to be inserted in cylindrical shell from the press-fit of cylindrical shell bottom, and the outer chamfering of bucket pipe pipe end of suction bucket is communicated with compressed air inlet suction port with the passage that the interior chamfering that water conservancy diversion blocks up through hole is formed.The utility model advantage is as follows: this product structure is simple, and the negative pressure produced by cylindrical shell compressed air air-flow is sucked the plastic glue strip in semi-molten state in crushing knife box and pulverizes, and guarantees that feeding process is smooth and easy, not putty, improves feeding efficiency.
Description
Technical field
The utility model relates to a kind of plastic granulator, more specifically to a kind of negative-pressure suction device of plastic granulator crushing knife box.
Background technology
LCP class raw material is all have employed at present in the electronic product such as communication, automobile coupling product, due to a large amount of material bars can be produced in product less event injection moulding production, and the expensive per kilogram unit up to a hundred that reaches of this material, it is the reduction cost of material that improves liquidity that usual connector injection moulding is produced, and allows the feed back dosed and do not surpass 20% in production.Therefore utilize material bar feed back to be directly connected to the cost of product.But the particularity due to this type of raw material: the adhesive tape that on the one hand this kind of plastics melt extrude when hot is very soft, is difficult to traction and controls, can not enter crushing knife box smoothly; Stiff especially after the cooling period on the other hand, after pulverizing, particle is uneven, directly can not mix in raw material and use, be between two fires.
Summary of the invention
The purpose of this utility model be provide for prior art weak point a kind of structure simple, can by smooth and easy for hot plastic glue strip, the not negative-pressure suction device of plastic granulator crushing knife box introduced of putty.
The purpose of this utility model is realized by following measures: a kind of negative-pressure suction device of plastic granulator crushing knife box, is characterized in that, includes that suction bucket, cylindrical shell, water conservancy diversion are stifled, compressed air inlet suction port; Wherein:
Described cylindrical shell is hollow form, and hollow form top, bottom are each stepped, and hollow form upper inside wall is provided with the screw thread screwed in for suction bucket, and the sidewall at the middle part of cylindrical shell is provided with the hole seat for installing compressed air inlet suction port;
The bucket pipe outer rim of described suction bucket is stepped, and bucket pipe outer rim end is provided with chamfering;
It is corresponding with cylindrical shell hollow form lower step shape that described water conservancy diversion blocks up outer rim, and the through hole porch that water conservancy diversion blocks up is provided with interior chamfering;
Described compressed air inlet suction port is arranged on the hole seat of cylinder lateral wall, suction bucket screws in the screw thread of cylindrical shell upper inside wall, the stair-stepping shaft shoulder of bucket pipe outer rim of suction bucket forms backflash mutually across a certain distance with the stair-stepping shaft shoulder in cylindrical shell hollow form top, the bucket pipe outer rim of suction bucket and the inwall of cylindrical shell hollow form leave gap, described water conservancy diversion is stifled to be inserted in cylindrical shell from the press-fit of cylindrical shell bottom, and the outer chamfering of bucket pipe pipe end of suction bucket is communicated with compressed air inlet suction port with the passage that the interior chamfering that water conservancy diversion blocks up through hole is formed.
Compared with prior art; the negative-pressure suction device of a kind of plastic granulator crushing knife box that the utility model proposes; tool has the following advantages: structure is simple; the negative pressure produced by cylindrical shell compressed air air-flow is sucked the plastic glue strip in semi-molten state in crushing knife box and pulverizes; guarantee that feeding process is smooth and easy, not putty, improve feeding efficiency.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the embodiment that the utility model proposes.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention is elaborated: shown in Fig. 1, give the embodiment that the utility model is different.In figure, a kind of negative-pressure suction device of plastic granulator crushing knife box, is characterized in that, includes that suction bucket 1, cylindrical shell 2, water conservancy diversion are stifled 3, compressed air inlet suction port 4; Wherein:
Described cylindrical shell 2 is in hollow form, and hollow form top, bottom are each stepped, and hollow form upper inside wall is provided with the screw thread screwed in for suction bucket 1, and the sidewall at the middle part of cylindrical shell 2 is provided with the hole seat for installing compressed air inlet suction port 4;
The bucket pipe outer rim of described suction bucket 1 is stepped, and bucket pipe outer rim end is provided with chamfering 11;
Stifled 3 outer rims of described water conservancy diversion are corresponding with cylindrical shell 2 hollow form lower step shape, and the through hole porch that water conservancy diversion blocks up is provided with interior chamfering 31;
Described compressed air inlet suction port 4 is arranged on the hole seat of cylindrical shell 2 sidewall, suction bucket 1 screws in the screw thread of cylindrical shell 2 upper inside wall, the stair-stepping shaft shoulder of bucket pipe outer rim of suction bucket 1 forms backflash 5 mutually across a certain distance with the stair-stepping shaft shoulder in cylindrical shell 2 hollow form top, the bucket pipe outer rim of suction bucket 1 and the inwall of cylindrical shell hollow form leave gap, described water conservancy diversion stifled 3 inserts in cylindrical shell 2 from the press-fit of cylindrical shell 2 bottom, and interior 31 jiaos of passages formed that the outer chamfering 11 of bucket pipe pipe end of suction bucket and water conservancy diversion block up through hole are communicated with compressed air inlet suction port 4.
The effect that backflash of the present utility model can play shunting, regulate.When compressed-air actuated pressure is excessive, air velocity can sharply amplify, and not only the fluctuation of device for suction material negative pressure even has fraction oppositely upwards to flow greatly, can make adsorption mechanism job insecurity.Have backflash rear portion air-flow evenly to flow out along material sucking port fuse surrounding again through backflash, peak load shifting, smooth air effect can be played like this.
Describe embodiment of the present utility model by reference to the accompanying drawings above; the structure that embodiment provides does not form restriction of the present utility model, and in this area, those skilled in the art make various distortion within the scope of the appended claims or revise all in protection domain.
