Abstract
The invention discloses an installation structure of transmission shafts in a conical double screw extruder special for polyolefine, which comprises a machine barrel, wherein a pair of conical screws is arranged in the machine barrel; one of the conical screws is connected with a driving transmission shaft, and the other conical screw is connected with a driven transmission shaft; the driving transmission shaft and the driven transmission shaft form a mesh type transmission through a pair of cone gears; as for the conical double screws of which the outer diameter of the maximum screw thread is 132 mm and the outer diameter of the minimum screw thread is 65 mm, the included angle between the driving transmission shaft and the driven transmission shaft is 2DEG 11'19'' to 2DEG20'0''; and as for the conical double screws of which the outer diameter of the maximum screw thread is 188 mm and the outer diameter of the minimum screw thread is 92 mm, the included angle between the driving transmission shaft and the driven transmission shaft is 1DEG52'39'' to 1DEG63'0''. The conical double screw extruder special for polyolefine, which is provided with the installation structure of the transmission shafts, can enhance the compounding and plastication effects of the polyolefine material.
Description
Technical field
The invention belongs to the conical double screw extruder field, relate in particular to the mounting structure of power transmission shaft in a kind of conical double screw extruder of the brand-new professional processing of polyolefins material of energy.
Background technology
Traditional conical double screw extruder comprises: machine barrel, in machine barrel, be provided with a pair of conical screw, on every conical screw, all be provided with feed zone, shunting section, compression section, choke section, exhaust section, plasticizing homogenizing zone totally six sections spiral shell ribs, machine barrel is provided with charging aperture and exhaust outlet, and the position correspondence of charging aperture the feed zone on the conical screw, the position of exhaust outlet faces the exhaust section on the conical screw, is connected with separately power transmission shaft respectively at an end of conical screw.Usually distinguish conical double screw extruder according to the size of maximum spiral shell rib on the screw rod and minimum spiral shell rib outside dimension, as maximum spiral shell rib external diameter is that 132 millimeters, minimum spiral shell rib external diameter are 65 millimeters 65/132 machine that is called, and maximum spiral shell rib external diameter is that 188 millimeters, minimum spiral shell rib external diameter are 92 millimeters 92/188 machine that is called.The conical double screw extruder of said structure can only be to the thermal sensitivity plastics---and plastify well with mixing as polyvinyl chloride (being called for short PVC) material, therefore be used to specialty processing thermal sensitivity plastics.But can not plastify well with mixing polyolefine material, can not be used for the processing of polyolefins material.
Summary of the invention
Technical problem to be solved by this invention is: the mounting structure that power transmission shaft in a kind of conical double screw extruder special for polyolefine of the mixing and plasticizing effect that can improve polyolefine material is provided.
In order to solve the problems of the technologies described above, technical scheme of the present invention is: the mounting structure of power transmission shaft in the conical double screw extruder special for polyolefine, comprise: machine barrel, in machine barrel, be provided with a pair of conical screw, described wherein conical screw is connected with final drive shaft in the distributor box by main shaft joint, another root conical screw is by being connected from power transmission shaft in shaft joint and the distributor box, final drive shaft with from power transmission shaft by the transmission that is meshing with each other of a pair of angular wheel; And for maximum spiral shell rib external diameter is that 132 millimeters, minimum spiral shell rib external diameter are 65 millimeters conical double-screw, final drive shaft and be that 2 degree 11 minutes and 19 seconds are between 2 degree 20 minutes and 0 second from the angle α between the power transmission shaft; For maximum spiral shell rib external diameter is that 188 millimeters, minimum spiral shell rib external diameter are 92 millimeters conical double-screw, final drive shaft and be that 1 degree 52 minutes and 39 seconds is between 1 degree 63 minutes and 0 second from the angle α between the power transmission shaft.
Advantage of the present invention is: the conical double screw extruder special for polyolefine that above-mentioned power transmission shaft mounting structure is housed can improve the mixing and plasticizing effect of polyolefine material, can be used for professional processing of polyolefins material, the output height, and it is little to consume energy.
