Description
Technical field
The utility model relates to the extruder that industries such as plastics, chemical industry, food are used, and is specifically related to a kind of extruding machine barrel cleaning mechanism.
Background technology
Along with extruder is constantly expanded in the application of industries such as plastic cement, chemical industry, food, the cleaning of extruder becomes an important step in all kinds of enterprise production process.Because screw rod can pull out cleaning, so that cleaning is got up is relatively convenient, and the cleaning of the inner chamber of the barrel that a plurality of unit couples together wants difficulty a lot.Safe, quick, economic cleaning barrel becomes the active demand that extruder uses producer.The method of using in existing the production is taken the barrel cleaning apart and is used the cleaning of barrel sander.
Take barrel cleaning apart and be about to the single-unit barrel and take its inner chamber of cleaning one by one apart, its shortcoming is: elapsed time is very long, and labour intensity is bigger, delays production.
Application number is that 200620042955.4 Chinese patent discloses " a kind of barrel sander ", disclosed screw rod extracted after, the polishing bar is put in the scheme of carrying out cleaning operation in the barrel.But there is potential safety hazard (as shown in Figure 3) in elongated rotating mechanisms such as polishing bar, and industrial accident has for several times taken place in the actual production, and the actuating unit that the rotation of polishing bar need be extra, need on-the-spot external power supply, and equipment and operating process take bigger space.
Same, application number is that 201020168449.6 Chinese patent discloses " polishing barrel cleaning device ", has disclosed the installation steel brush on horizontal brace rod, utilizes the motor of peripheral hardware to carry out cleaning operation.
The utility model content
At the problem that above-mentioned prior art exists, the purpose of this utility model is, provides a kind of mechanism cleaning effect good, and compact conformation need not extra actuating unit, safe extruding machine barrel cleaning mechanism.
To achieve these goals, the technical solution of the utility model is: a kind of extruding machine barrel cleaning mechanism, be used to clear up the inner chamber of the barrel of extruder, comprise the spline adapter sleeve on the extruder, the spline adapter sleeve is connected with the transmission case of extruder, also comprise drive mandrel, clear material, drive mandrel is packed into and is connected with the spline adapter sleeve behind the barrel, and the clear material is housed on the drive mandrel.Clear material on the drive mandrel provides power to clear up extruding machine barrel by the transmission case of extruder itself.
Further, be with a sleeve on drive mandrel, the clear material is located at sleeve outer surface, and drive mandrel and sleeve constitute the feed screw nut transmission mechanism.Utilize the transmission principle of feed screw nut, make the action of better polishing of clear material, cleaning effect is good, and security is higher.
Further, the screw thread drive mechanism of described feed screw nut transmission mechanism is ball-screw or trapezoidal thread transmission.
Further, better be fixed on the sleeve in order to make the clear material, described clear material is connected with spring, and spring one end is connected with the clear material, and the other end is connected with a trim ring of being located at sleeve; Clear material and spring junction are provided with clamp nut.
Further, the dismounting of clear material for convenience, sleeve is provided with the screw thread with described clamp nut engagement, and clamp nut is located on the sleeve corresponding position with the barrel charge door.
Further, the external diameter of described clear material is more bigger than barrel internal diameter, the clear material with contact better, clean-up performance is better.
Preferably, described clear material is glass cloth or nonwoven, has certain pliability.
Compared with prior art, the utlity model has following advantage: the one, utilize the original transmission case of extruder that polishing power is provided, need not to establish in addition motor, simple in structure, easy to operate; The 2nd, adopt " leading screw-nut " transmission mechanism, the polishing cleaning effect is good, makes particle be difficult for the bonding caking, and operating noise is little; The 3rd, security is good, equipment firm wear-resisting and work in can not pollute material.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model structure explosive view;
Fig. 3 is existing barrel sander structural representation.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail:
As shown in Figure 1 and Figure 2, a kind of extruding machine barrel cleaning mechanism, be used to clear up the inner chamber of the barrel 8 of extruder, comprise spline adapter sleeve 1, drive mandrel 2, clear material 6 on the extruder, spline adapter sleeve 1 is connected with the transmission case of extruder, drive mandrel 2 barrel 8 back of packing into is connected with spline adapter sleeve 1, and clear material 6 is housed on the drive mandrel 2.Also be with a sleeve 7 on drive mandrel 2, clear material 6 is located at sleeve 7 outer surfaces, and drive mandrel 2 and sleeve 7 constitute the feed screw nut transmission mechanism, and the screw thread drive mechanism of feed screw nut transmission mechanism can be ball-screw or trapezoidal thread transmission.Clear material 6 also is connected with spring 4 in barrel 8 charge door corresponding positions, and spring 4 one ends are connected with clear material 6, and the other end is connected with a trim ring 3 of being located at sleeve 7; Clear material 6 is provided with clamp nut 5 with spring 4 junctions.Sleeve 7 is provided with screw thread and clamp nut 5 engagements, causes 6 deformation of clear material thereby compress spring 4 vertically by clamp nut 5, makes it to contact with barrel 8; The external diameter of clear material 6 is more bigger than barrel 8 internal diameters, for glass cloth or nonwoven etc. have certain flexible material.
When polishing prune job, after extruder screw extracted, elder generation overlaps clear material 6 or is wrapped on the sleeve 7, be inserted in trim ring 3, spring 4 more successively, by being threaded into clamp nut 5 on the sleeve 7, the sleeve 7 that will assemble above-mentioned parts then rotates to the bottom of thread of drive mandrel 2 along the feed screw nut transmission, after the assembling as shown in Figure 1.The drive mandrel 2 that assembles above-mentioned parts is packed in the extruding machine barrel 8, and link to each other with the transmission case output shaft of extruder by spline adapter sleeve 1.Thereby cause clear material 6 deformation with instruments such as screwdriver, hammer rotations clamp nut 5 with compression spring 4 by barrel 8 charge doors, the certain radial pressure of generation when making it contact with barrel 8.The low rate start extruder, the moment of torsion of extruder is delivered on the drive mandrel 2, along with the rotation of drive mandrel 2, sleeve 7 is at the effect lower edge of feed screw nut transmission drive mandrel 2 axial moving linearlies, thereby realizes the polishing clearing function by the frictional force between clear material 6 and the barrel 8.
Above embodiment only is used to illustrate the technical solution of the utility model, is not intended to limit; Although the utility model is had been described in detail with reference to preferred embodiment; those of ordinary skill in the field are to be understood that; still can make amendment or the part technical characterictic is equal to replacement the specific embodiment of the present utility model; and not breaking away from the spirit of technical solutions of the utility model, it all should be encompassed in the middle of the technical scheme scope that the utility model asks for protection.
