Description
(1) technical field
The present invention relates to a kind of servicing unit, particularly relate to a kind of sanding apparatus screw of plastic extruder at modified plastics field plastic extruder.
(2) background technology
In plastic extruding forming equipment, plastic extruder is referred to as main frame usually, and the follow-up equipment plastic extruding forming machine supporting with it then is called subsidiary engine.Plastic extruder derives twin-screw, multiscrew by original single screw rod through 100 years of development, even does not have different types of machines such as screw rod.Plastic extruder (main frame) can mate with various plastic shaping subsidiary engines such as tubing, film, handful material, monofilament, flat filament, strap, crowded net, plate (sheet) material, profile shapes, granulation, cable coatings, form various plastic extruding forming production lines, produce various plastic products.Therefore, no matter now or in the future plastic extruding forming machinery all be one of machine of being used widely in the plastic processing industry.
The main frame of plastic extruder is an extruding machine, and it is made up of extrusion system, transmission system and heating and cooling system.
Extrusion system mainly comprises screw rod, machine barrel, hopper, head and mould, and plastics plastify into uniform melt by extrusion system, and in this course under institute's build-up pressure, by the continuous extruder head of screw rod.
Screw rod: be the main parts of extruding machine, it is directly connected to the range of application and the productivity ratio of extruding machine, is made by the steel alloy of high-strength corrosion-resisting.
Machine barrel: be a metallic cylinder, generally with heat-resisting, compressive resistance is higher, the composite steel tube of firm wear-resisting, corrosion resistant steel alloy or liner steel alloy is made.Machine barrel cooperates with screw rod, realizes the pulverizing to plastics, softening, fusion, plasticizing, exhaust and compacting, and evenly carries sizing material continuously to formation system.The length of general machine barrel is 15～30 times of its diameter, so that plastics are fully heated and abundant plasticizing is principle.
Hopper: feed hopper bottom is equipped with cutting device, so that adjust and cut off materials flow, the side of hopper is equipped with window and is demarcated metering device.
Head and mould: head is made of cover and carbon steel overcoat in the steel alloy, mould is housed in the head, the effect of head is that the plastic melt that will rotatablely move changes the parallel lines motion into, in the importing die sleeve of uniform and stable, and gives the briquetting pressure of plastics with necessity.
During modified plastics is produced, often need produce different products, when the replacing different product, just have cleaning, when cleaning, need to such an extent that the dial-out of the screw rod in the extruder is polished extruder by same extruder.
Conventional at present polishing mode is that screw rod cooling is earlier polished off with the hand sand machine material on the screw rod then with its material.So there is following defective in the polishing mode, one, the operative employee must concentrate by energy when using manual angle grinding machine in bruting process, and polishing overlong time, the cover of polishing according to statistics needs spend man-hour more than 3 hours during screw rod, there is carelessness can have very big potential safety hazard slightly as operative employee's notice in the meantime, hurts sb.'s feelings, hinder accidents such as hand; Its two, because of using the hand sand overlong time, influence manufacturing schedule.
(3) summary of the invention
Purpose of the present invention is intended a kind of screw rod sanding apparatus is provided, and overcomes and changes form by operative employee's hand sand screw rod, to overcome the potential safety hazard that original manually-operated exists, accelerates polishing speed, raising production work efficient.
Purpose of the present invention is realized by following technical scheme:
A kind of screw of plastic extruder sanding apparatus, it is characterized in that: described screw rod is placed on two cradling pieces that vertically dispose in two ends, between two cradling pieces, parallel, optical axis of horizontal arrangement and a lead screw shaft, slide arrangement one motor bracing frame on optical axis and lead screw shaft, bracing frame cooperates with optical axis with unthreaded hole, bracing frame is with nut and lead screw shaft threaded engagement, motor is set on bracing frame, and fixing polishing wire wheel on the output shaft of motor is at lead screw shaft termination configuration turning handle.
Further, the support frame as described above height can be adjusted up and down.
Further again, support frame as described above is two parts up and down, is connected in elongated slot by bolt.
Further, described motor output shaft is parallel with extruder screw.
Adopt the technical program, screw rod to be polished is placed on two cradling pieces that vertically dispose in two ends, rotary electric machine, the polishing wire wheel rotates, and the screw rod to be polished of the top of can polishing is because the unthreaded hole of bracing frame is subjected to placing restrictions on of optical axis, by manual rotation turning handle, turning handle interlock lead screw shaft is rotated, and makes the bracing frame that is cooperated by nut thread to walk along lead screw shaft, polishing wire wheel top wait the to polish whole length of screw rod of can polishing.With manually rotating top wait the to polish angle of screw rod slightly, turning handle moves a bracing frame again, comprises moving of polishing wire wheel, again an angle of the clean polishing of polishing screw rod.By that analogy, whole angles of the clean extruder screw of polishing are finished polishing operation.
The invention has the beneficial effects as follows that the device overall structure is simple, easy to use, improved the efficient of polishing screw rod greatly, changed the potential safety hazard of not concentrating existence because of energy in the operation.
(4) description of drawings
Fig. 1 is the configured in one piece structure chart of a kind of embodiment of screw of plastic extruder sanding apparatus of the present invention;
Fig. 2 be Fig. 1 wherein support frame component be two parts up and down, the simplified schematic diagram that in elongated slot, connects by bolt.
Among the figure: the 1st, handle, the 2nd, cradling piece, the 3rd, lead screw shaft, the 4th, bracing frame, the 5th, optical axis, the 6th, polishing wire wheel, the 7th, motor, the 8th, screw rod.
(5) specific implementation method
Below in conjunction with accompanying drawing, the present invention is elaborated:
A kind of screw of plastic extruder sanding apparatus, described screw rod 8 is placed on two cradling pieces 2 that vertically dispose in two ends, between two cradling pieces 2, parallel, optical axis 5 of horizontal arrangement and a lead screw shaft 3, slide arrangement one bracing frame 4 on optical axis 5 and lead screw shaft 3, bracing frame 4 cooperates with optical axis 5 with unthreaded hole, bracing frame 4 is with nut and lead screw shaft 3 threaded engagement, motor 7 is set on bracing frame 4, fixing polishing wire wheel 6 on the output shaft of motor 7 is at the termination of lead screw shaft 3 configuration turning handle 1.
Support frame as described above 4 is two parts up and down, is connected in elongated slot by bolt, and structure can realize the adjustment of bracing frame 4 height very simply and easily thus.
Described motor 7 output shafts are parallel with extruder screw 8, to guarantee to be installed in the screw rod 8 above polishing after wire wheel 6 rotation on the output shaft.
As shown in Figure 1, screw rod 8 is placed on the cradling piece 2, and optical axis 5 and lead screw shaft 3 are fixed on the bracing frame 4, handle 1 is fixed on the screw axis 3, optical axis 5 and lead screw shaft 3 are interspersed in the unthreaded hole and nut bore of bracing frame 4, and motor 7 is fixed on the bracing frame 4, and polishing wire wheel 6 is fixed on motor 7 output shafts.Motor is connected power supply make wire wheel 6 transhipment at a high speed, screw rod 8 is polished, rotating screw bolt 8 and handle 1 are regulated bracing frame 4 and are moved forward and backward, and to reach are polished in screw rod 8 front and back.
By above-mentioned public technology scheme as seen, advantage of the present invention is very clear and definite, and is simple in structure easy to use, and polishing is clean, and the high efficiency of especially polishing has been eliminated potential safety hazard, and practicality is high.
