Abstract
The utility model relates to a plastifying extruding mechanism of a reciprocating type single-screw extruder. The plastifying extruding mechanism comprises a screw rod and a machine barrel, wherein the screw rod is sleeved with the machine barrel; the screw rod and the machine barrel are fixedly arranged on a transmission box of the extruder; a core shaft of the screw rod is provided with a mixing screw block and a conveying screw block along the axial direction; each of the mixing screw block and the conveying screw block, and a rod body of the screw rod are integrally molded; the machine barrel is an integral barrel body; a screw rod sleeve which is used for fixing the front end of the screw rod to prevent the rod body from shaking is arranged at the front end of the barrel body; a heat-conduction oil hole is further formed in the end face of the connection end between the screw rod and the transmission box of the extruder along the axial direction. The plastifying extruding mechanism of the reciprocating type single-screw extruder is convenient to mount and detach, high in durability and capable of effectively preventing the screw rod from shaking.
Description
Technical field
The utility model relates to reciprocating single-bolt extruder, relates in particular to the plasticizing extruder structure of reciprocating single-bolt extruder.
Background technology
The plasticizing extruder structure of reciprocating single-bolt extruder all comprises a machine barrel and a screw rod, the cylindrical shell of machine barrel generally adopts split type structure, screw rod is positioned in the cylinder chamber of machine barrel, on screw mandrel, be socketed with various independently mixing spiral shell pieces and carry spiral shell piece, same one end of machine barrel and screw rod is all fixed on transmission case, and screw rod is driven and is rotated and seesaws by this transmission case.
The plasticizing extruder structure of said structure exists following defect: its machine barrel adopts split type structure, causes installation, dismounting all to be wasted time and energy; Mixing spiral shell piece on its screw rod and conveying spiral shell piece are independent member, are sleeved on one by one on screw rod, higher to the requirement on machining accuracy of screw rod and spiral shell piece, otherwise easily form cumulative errors problem, and then affect service life; One end of its screw rod is fixed, and the other end is unsettled, easily shake when work.
Utility model content
Above-mentioned defect for the plasticizing extruder structure of existing reciprocating single-bolt extruder, the utility model discloses a kind of installation, dismantle more convenient, outputting torsion is larger, longer service life and can effectively prevent the plasticizing extruder structure of the reciprocating single-bolt extruder of screw rod shake.
The technical solution of the utility model is as follows:
A kind of plasticizing extruder structure of reciprocating single-bolt extruder, comprise screw rod and be socketed on the machine barrel outside described screw rod, described screw rod and machine barrel are all fixed on extruder transmission case, on the mandrel of described screw rod, be provided with vertically mixing spiral shell piece and carry spiral shell piece, described mixing spiral shell piece and conveying spiral shell piece are all formed in one with the shaft of described screw rod;
Described machine barrel is a monoblock type cylindrical shell, the front end of its stack shell be provided with a fixing described screw rod front end, prevent the screw sleeve of its shaft shake.
As the further improvement of such scheme, the end face of described screw rod and extruder transmission case link is also provided with a heat conduction oilhole vertically.
Plasticizing extruder structure compared to existing reciprocating single-bolt extruder, because machine barrel of the present utility model is monolithic construction, during installation, without two machine barrel splits are combined and are fixed together in advance, only its rear end need be fixed, install, dismantle all more convenient; Mixing spiral shell piece of the present utility model and conveying spiral shell piece are all formed in one with the shaft of described screw rod, and the spiral shell piece installing than cover has larger outputting torsion and stronger durability; Because the two ends of screw rod of the present utility model are all fixed, the jitter amplitude of shaft in the time of can effectively reducing work; In addition, at the link end face of screw rod and transmission case, be provided with a heat conduction oilhole, logical cocycle conduction oil in oilhole, can play thermolysis to the screw rod of rotation.

Fig. 1 is the general structure schematic diagram of the utility model embodiment
Fig. 2 is the general structure explosive view of the utility model embodiment
In figure, be labeled as: 1, screw rod, 11, mixing spiral shell piece, 12, carry spiral shell piece, 13, heat conduction oilhole, 2, machine barrel, 21, screw sleeve.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described.
See figures.1.and.2:
A kind of plasticizing extruder structure of reciprocating single-bolt extruder, comprise screw rod 1 and be socketed on the machine barrel 2 outside described screw rod 1, described screw rod and machine barrel 1,2 are all fixed on extruder transmission case, on the mandrel of described screw rod 1, be provided with vertically mixing spiral shell piece and carry spiral shell piece 11,12, described mixing spiral shell piece and conveying spiral shell piece 11,12 are all formed in one with the shaft of described screw rod 1;
Described machine barrel 2 is a monoblock type cylindrical shell, the front end of its stack shell be provided with a fixing described screw rod 1 front end, prevent the screw sleeve 21 of its shaft shake.
Described screw rod 1 is also provided with a heat conduction oilhole 13 vertically with the end face of extruder transmission case link.
Principle of the present utility model is: screw rod 1 is inserted from the rear end nozzle of machine barrel 2, the front end of screw rod 1 is fixed in the screw sleeve 21 of machine barrel 2 front portions, the rear end of machine barrel 2 is fixed on transmission case body, the rear end of screw rod 1 is fixedly connected with the drive in transmission case, by this drive band action rotation and front and back reciprocating.
