Abstract
The utility model provides a retrieve screw rod for granulator, there is the cutting axle sleeve including fixed rotating shaft, thread bush, the outside cover of thread bush, be equipped with the screens on the fixed rotating shaft, the thread bush block is in the screens, and the thread bush is including connecting gradually first screw thread section, second screw thread section, third screw thread section, and the diameter of first screw thread section, second screw thread section, third screw thread section reduces in proper order, be connected with the cutting axle sleeve in the third screw thread section, be provided with a plurality of blown down tanks in the inner wall axial of cutting axle sleeve, this screw rod during operation, plastic materials moves towards between cutting axle sleeve and the thread bush along the thread bush, relative motion between cutting axle sleeve and the thread bush, plastic materials receives between blown down tank and third screw thread section and tears to shreds, extrude, plastic materials is along the blown down tank ejection of compact, and because the rotation of thread bush, form plastic pellet, the process that does not have heating and melting, the cutting of physics nature completely, and the particle diameter is little, accord with the production requirement, the fog nature that has also kept plastic materials.
Description
Technical field
This utility model relates to pelletizer equipment parts technical field, particularly relates to a kind of recovery screw for pelletizer。
Background technology
Comminutor is mainly used in processing waste plastic film。Including industrial packaging film, agricultural film, awning film, medicated beer bag, handbag, woven bag, agricultural convenient bag, basin, bucket, carafe, furniture, articles for daily use etc., it is applicable to the waste or used plastics that major part is common, it is that waste plastic regeneration industrial applications is the widest, use the most extensive, plastic reclaimed processing equipment the most popular with users, in existing technology, comminutor is important is pass through high-temperature fusion, plasticizing, the physical property of the process change plastics of extrusion, reach the plasticizing to plastics and molding, so generally melting plant all can be provided with, but plastics melted time, high temperature can make the mist of plastics lose, the plastic pellet mist produced is poor。
Utility model content
For solving above-mentioned technical problem, the utility model proposes a kind of recovery screw for pelletizer, be cased with cutting axis set including outside fixed rotating shaft, thread bush, described thread bush；Described fixed rotating shaft is provided with screens, and described thread bush is sticked in described screens, and described thread bush includes being sequentially connected with the first thread segment, the second thread segment, the 3rd thread segment, described first thread segment, the second thread segment, the 3rd thread segment diameter be sequentially reduced；Being connected to described cutting axle sleeve on described 3rd thread segment, the inwall of described cutting axle sleeve is axially provided with some blow tanks。
Preferably, being cased with sleeve outside described fixed rotating shaft, described sleeve is provided with charging aperture, and described charging aperture stretches to described fixed rotating shaft。
Preferably, described cutting axle sleeve is provided with annular mounting groove towards the face of described first thread segment, is provided with female thread in described annular mounting groove, and described sleeve is threaded onto on described female thread。
Preferably, the fixed rotating shaft between described thread bush and described fixed rotating shaft is provided with some oil grooves caved in。
Preferably, the fixed rotating shaft stretching out described first thread segment is provided with conical section, and described conical section is provided with fine thread。
The recovery screw for pelletizer that the utility model proposes has following beneficial effect: during the work of this screw rod; plastic material threadingly overlaps and moves towards between cutting axle sleeve and thread bush; relative motion between cutting axle sleeve and thread bush; plastic material receives between blow tank and the 3rd thread segment and tears up; extrusion; plastic material is along blow tank discharging; and due to the rotation of thread bush; form plastic pellet; do not add the process of heat fusing, be entirely the cutting of physical property, and particle diameter is little; meet production requirement, also maintain the mist of plastic material。

Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described。
As shown in Figure 1, Figure 2, Figure 3 shows, the utility model proposes a kind of recovery screw for pelletizer, overlap 3 including fixed rotating shaft 1, thread bush 2, the outside cutting axis that is cased with of described thread bush 2；Described fixed rotating shaft 1 is provided with screens 4, and described thread bush 2 is sticked in described screens 4, and screens 4 prevents thread bush 2 sliding axially along fixed rotating shaft 1；Described thread bush 2 includes first thread segment the 5, second thread segment the 6, the 3rd thread segment 7 being sequentially connected with, as shown in Figure 4, the diameter of described first thread segment the 5, second thread segment the 6, the 3rd thread segment 7 is sequentially reduced, and the diameter being sequentially reduced contributes to plastic material along screw sleeve 2 transmission to cutting axle sleeve 3；Described 3rd thread segment 7 is connected to described cutting axle sleeve 3, the inwall of described cutting axle sleeve 3 is axially provided with some blow tanks 8, blow tank 8 and the 3rd thread segment 7 are fitted, the direction of blow tank 8 is intersected with the 3rd thread segment 7 top discharge passage, plastic material is subject to rubbing and extruding between cutting axle sleeve 3 and the 3rd thread segment 7, plastic material, along blow tank 8 discharging, is added owing to thread bush 2 for for oblique, cutting into particle discharging by plastic material。
When this screw rod uses, being installed in the sleeve 9 of comminutor, described sleeve 9 is provided with charging aperture 10, and described charging aperture 10 stretches to described fixed rotating shaft 1, and plastic material enters from charging aperture 10, is sent to cutting axle sleeve 3 place along screw sleeve。
Wherein, sleeve 9 is connected with cutting axle sleeve 3, described cutting axle sleeve 3 is provided with annular mounting groove 11 towards the face of described first thread segment 5, it is provided with female thread in described annular mounting groove 11, described sleeve 9 is threaded onto on described female thread, sleeve 9 is provided with the external screw thread matched with female thread, and is threaded onto on cutting axle sleeve 3。
Owing to there is frictional force between fixed rotating shaft 1 and thread bush 2, during rotation, fixed rotating shaft 1 and thread bush 2 can be damaged, so fixed rotating shaft 1 between described thread bush 2 and described fixed rotating shaft 1 is provided with some oil grooves 12 caved in, it is provided with lubricating oil in oil groove 12, ensure lubricity between the two, it is prevented that abrasion。
Preferably, the fixed rotating shaft 1 stretching out described first thread segment 5 is provided with conical section 13, and described conical section 13 is provided with fine thread, it is simple to be connected with head and discharging。
The multiple amendment of embodiment be will be apparent from for those skilled in the art, and generic principles defined herein when without departing from spirit or scope of the present utility model, can realize in other embodiments。Therefore, this utility model is not intended to be limited to the embodiments shown herein, and is to fit to the widest scope consistent with principles disclosed herein and features of novelty。
