Abstract
The utility model relates to a connecting device of a screw of a waste plastic extruder. The connecting device comprises a feed screw, an exhaust ring, a compensation ring, a fusing screw and a screw connecting piece. The connecting device is characterized in that the screw connecting piece is a double end stud type part, and the feed screw and the fusing screw can be connected into a whole. The connecting device disclosed by the utility model has the advantages of simple structure, easiness for material seeking and easiness for processing, and most importantly, the service life of an imported screw is prolonged and the usage cost of the imported screw is reduced.
Description
Technical field
The utility model relates to a kind of jockey of waste plastic extruding screw rod.
Background technology
The structure of import screw rod is, it is made up of feed worm and melting screw rod two joints, and their connection is as a whole by being formed by connecting of the screw thread of melting screw rod end and the screwed hole of feed worm end.In the course of the work, because the viscosity of material is high, the moment of torsion of generation is large, and the moment of torsion maximum that the screw thread neck place of melting screw rod end is subject to, under long-term strong torsional interaction, the screw thread neck place fracture of melting screw rod end.If we are this model screw rod of import again, the fund of minimum 120,000 yuan, this is for small-sized company's financial difficulty; If will then process use in its neck place repair welding, work in-process centering difficulty, difficulty of processing are large.
Summary of the invention
The utility model is for solving reparation and the quick-replaceable connectivity problem of fracture screw rod.
The technical scheme addressing the above problem is: original feed worm head is processed to a seam, make it ensure the location of bolt jointing part; Original melting screw head is processed to screwed hole, make it ensure being connected of bolt jointing part and melting screw rod.Increase a bolt jointing part, with it, feed worm and melting screw rod coupled together, and ensure the length of original whole screw rod and function constant.
Beneficial effect: a kind of improvement of jockey of waste plastic extruding screw rod, the screw rod having ruptured is re-started to process and assemble, and ensure the length of original whole screw rod and function constant.So not only improve the utilization rate of former screw rod, and extended the service life of import screw rod.The screw rod import of a present same model needs 120,000 yuan, and we process the fund that a bolt jointing part only needs thousand yuan of less thaies, the import screw rod of a same model can use 3 to 4 campaigns, and can use a campaign in the good situation of connector, just calculate by half campaign, in the situation that other all can't harm if rupture in the neck place that former screw rod is junction, just ensure 4 campaigns, so just can save 4000 yuan by 8 bolt jointing parts.The life that simultaneously makes screw rod due to its use, has reduced production cost significantly.
Brief description of the drawings
The jockey of a kind of waste plastic extruding screw rod of Fig. 1.
In figure: 1 is feed worm, 2 is exhaust flange, and 3 is compensated loop, and 4 is melting screw rod, and 5 is bolt jointing part.
Detailed description of the invention
Fig. 1 describes a kind of jockey structure chart of waste plastic extruding screw rod, comprises feed worm, air exhaust loop, compensated loop, melting screw rod, bolt jointing part.In the time that material enters feed worm place, material limit heating edge is carried, when material is heated to certain temperature, material just melts, and produces certain gas, carries out exhaust by exhaust flange, has expected the further melting homogeneous micronization of melting spiro rod section, to produce qualified pellet.Can find out from its production technology, because the viscosity of material is large, the moment of torsion of generation is large, easily makes the neck place fracture of bolt jointing part, just directly changes bolt jointing part.So constantly the former screw rod of Reusability, scraps until screw rod cannot be repaired.
Claims (4)
1. the jockey of a waste plastic extruding screw rod, comprised feed worm, air exhaust loop, compensated loop, melting screw rod, bolt jointing part, it is characterized in that bolt jointing part is that a studs type part can be connected as a whole feed worm with melting screw rod simultaneously.
2. the jockey of a kind of waste plastic extruding screw rod according to claim 1, is characterized in that bolt jointing part is a studs type structure.
3. according to the jockey of a claim 1 waste plastic extruding screw rod, the middle part that it is characterized in that bolt jointing part is a cylinder boss, for location.
4. the jockey of a kind of waste plastic extruding screw rod according to claim 1, is characterized in that bolt jointing part can be connected feed worm as a whole with melting screw rod simultaneously.
