Description
Technical field
The invention belongs to the plastic processing machinery field, specifically a kind of energy-saving self-traction strand pelletizer for plastic extruder.
Background technology
The granulation mode of plastic extruder mainly comprises two kinds of tie rod pelletizing (cold cut) and die face cuttings (earnestly); wherein the tie rod pelletizing refers to that extruding material strip by extruder cools off in air by the tank cooling or by conveyer belt, and cooled material strip is cut into 2～5mm particle in pelleter.
General pelleter is the towed pelleter with the traction rubber roll apparatus now; the power transmission shaft of pelleter is by the carry-over pinch rolls interlock of linkage part and draw-gear; the driving carry-over pinch rolls rotate; carry-over pinch rolls traction material strip enters the pelleter pelletizing; be the Chinese invention patent application of CN101138870A such as publication number; disclose a kind of " pelleter that is used for the plastic extruder stretching and granulation "; it comprises metal machine frame; be installed on the pelletizing chamber on the frame; power transmission shaft an end be connected with motor by drive disk assembly; the other end extends into joint grain indoor location moving knife; at the indoor stationary knife seat that is fixed with of pelletizing; power transmission shaft is by linkage part and draw-gear interlock, and this machinery is provided with annular coolant guiding channel around drive bearing.
There is following shortcoming in above-mentioned existing strand pelletizer: always continuous operation of pelleter in enterprise production process, in case draw-gear is malfunctioning, cause normally feeding of pelleter, thereby impact is produced, and draw-gear complex structure, maintenance trouble, have influence on further the normal operation of production line; The cooling of tradition pelleter generally will be equipped with blower and utilize compressed air to carry out cool-down dehumidification, and it is larger to consume energy; The trailer-type machine complex structure, production cost and maintenance cost are higher.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of energy-saving self-traction strand pelletizer for plastic extruder, adopts the self-traction structure to substitute traditional traction device, simplifies complete machine structure, reduces cost; The pelletizing indoor air flow strengthens, and has substituted traditional cooling system, environmental protection and energy saving; But pelletizing blade single-piece is replaced, Decrease production cost and maintenance cost.
The present invention will solve above-mentioned technical problem, is to be achieved by following technical scheme:
A kind of energy-saving self-traction strand pelletizer for plastic extruder, comprise metal machine frame, rack-mounted pelletizing chamber and pellet gathering-device, the pelletizing chamber comprises grain-cutter and the outdoor cover of pelletizing, its special feature is that grain-cutter comprises cutter shaft and the moving knife blade that is fixedly installed on the cutter shaft, be interval with vertically the tooth form knife film trap on the cutter shaft, the ring gear of each insert groove is uniform around cutter shaft, and the cutter shaft radius at each tooth and place, its position is the acute angle setting; Both sides, pelletizing chamber are fixed with respectively two radian bearings, and an end bearing of cutter shaft is on the radian bearing, and the other end extends after the supporting of radian bearing and is connected with motor through drive disk assembly.
There is tooth 10-14 on the described insert groove.
Described acute angle is 30-60 °.
Described drive disk assembly is belt and pulley assembly.
The frame bottom is equiped with at least three castors, and wherein at least one castor is universal wheel.
The frame bottom is equiped with at least three height-adjustable adjusting bolts.
Design feature of the present invention is as follows:
1. grain-cutter comprises cutter shaft and the moving knife blade that is fixedly installed on the cutter shaft, is evenly equipped with the tooth form knife film trap on the cutter shaft, the in a certain angle setting of cutter shaft radius at each insert groove and place, its position.Cutting knife has forward tractive force to material strip in the pelletizing process; The centrifugal force that produces owing to the cutting knife High Rotation Speed simultaneously falls at the indoor air pressure that causes of pelletizing; pelletizing indoor and outdoor air pressure unbalanced; become and to make material strip be subject to forward draw at pelletizing chamber inlet place; thereby abandoned the draw-gear of traditional towed pelleter; realize from drawing purpose; saved the traction power that original draw-gear needs, and complete machine structure is simplified saving manufacturing cost and maintenance cost.
In addition, because this design feature strengthens the pelletizing indoor air flow, substituted the pressure-air cooling system of traditional strand pelletizer, can reach energy-conservation purpose, complete machine is environmental protection more.
The pelleter of this structure has saved stationary knife, and its moving knife blade is the unified standard type, can replace, thereby further save manufacturing cost and maintenance cost.
2. described acute angle is 30-60 °, and the direction of rotation lopsidedness of teeth directional cutter shaft can guarantee the turn effect in the machine operation procedure to the full extent, thereby realizes from drawing purpose and certainly cooling off effect.Angle is large or less then by rotating produce relatively poor from traction effect and flow rotation effect again, can not satisfy well the requirement that machine runs well.
3. the quantity of tooth and moving knife blade is designed to 10-14 on the insert groove, can guarantee best production efficiency and pelletizing effect.Quantity is too large, and then separating effect is not good enough after the pelletizing; The too little production effect that directly affects again of quantity, therefore preferential knife number is 10-14.
4. drive disk assembly adopts belt and pulley assembly, is guaranteeing to simplify whole structure under the prerequisite that machine runs well as far as possible, reducing production costs and maintenance cost, increasing the service life.
5. the castor and the universal wheel that are equiped with bottom the frame can make things convenient for the moving and location of moving of complete machine.
6. the design of height bolt is regulated in frame bottom, be for the ease of fine setting complete machine height with in just spend, be used for the complete machine location, operate steadily guaranteeing.
To sum up, the present invention compared with prior art its obtained technological progress be:
The pelletizing process implementation is save power traction from traction, and simplified structure reduces cost, energy-conservation electric energy;
The abandoning tradition cooling system is realized from cooling, simplified structure, and cost is saved in environmental protection and energy saving;
The pelletizing blade can be damaged part and upgrade displacement, reduces cost of manufacture and maintenance cost.
The present invention is applicable on the plastic extruder as energy-saving self-traction strand pelletizer.
The present invention is described in further detail below in conjunction with Figure of description and specific embodiment.
