Abstract
An oil-temperature controlled extruder screw comprises a screw, a rotating coupling, an oil pipe and an oil circulation temperature controller, and is characterized in that oil is output by the rotating coupling from the oil circulation temperature controller to the screw through the oil pipe, and is returned to the oil circulation temperature controller through an oil return hole on the screw torealize circulation. The novel oil-temperature controlled extruder screw is adopted for achieving plastic extrusion technology with a small melt index range (such as PE foam, LSOH, as well as FEP); and compared with the prior art, the utility model adopts a screw direct heating method, so that the temperature of the screw can be controlled according to the physical property of extruded materials,the accuracy of the temperature control of the screw can reach plus or minus 1 DEG, and the plasticizing efficiency of the plastic can be ensured, thereby enabling China's plastic extrusion technologyto reach the advanced international standards.
Description
One. technical field:
The extruder screw of the utility model oil temperature control, what relate to is cable equipment design and manufacturing technology field, being applied to high-quality wideband data cable and railway digital signal cable insulated single wire manufactures, being specially adapted to the less plastics of melt index scope extrudes, as PE and PVC foamed material, materials such as low smoke and zero halogen and FEP.
Two. background technology:
The quality of production of insulated single wire has determined the wideband data cable, whether the quality of railway digital signal cable and foamed coaxial cable final products can reach the world/request of national standard, the mode of heating of tradition extruder adopts the aluminium block heat form, sleeve is heated, heat passes to heat on the screw rod by extruded material, because this indirect heat transfer mode makes the temperature control precision of extrusion screw rod low, cause the plasticizing capacity of plastics poor easily, directly influence the technical performance of insulated single wire.
Three. summary of the invention:
The purpose of the extruder screw of the utility model oil temperature control is, adopt a kind of novel screw rod heating temperature control mode, heat simultaneously by sleeve and screw rod, reach the temperature control requirement of the required extruded material of insulating exruded production, material temperature is controlled at ± the 1 degree margin of tolerance in, guarantee extruded material plasticizing capacity evenly.
Its technology is achieved in that
The extruder screw of oil temperature control, comprise screw rod, the rotation shaft joint, oil circulating temperature controller, vitta structure, it is characterized in that: the oily circulating temperature controller of the temperature control module of employing band PID function is controlled the temperature of extrusion screw rod, set required screw rod oil Wen Wendu according to the physics plasticizing capacity of material, screw rod connects oily circulating temperature controller by the rotation shaft joint, by oil pipe oil is imported in the screw rod, spill port by screw rod makes oil flow back to oily circulating temperature controller through the rotation shaft joint again, thereby forms the temperature that screw rod is controlled in circulation.
Its obvious advantage is: compare with the screw rod of domestic traditional extruder, the extruder screw of novel oily temperature control has that heat temperature raising speed is fast, and extruder temperature is controlled easily, and the extruder temperature control accuracy is up to ± 1 degree, and the plasticizing capacity of plastics is guaranteed.
Four. description of drawings:
Fig. 1 is that the extruder screw of the utility model oil temperature control is applied to the structural representation in the extruder.
Fig. 2 is the local enlarged diagram of extruder screw of the utility model oil temperature control.
Wherein: 1-reduction box, 2-screw rod, 3-rotation shaft joint, 4-sleeve, 5-oil circulating temperature controller, 6-oil pipe, 7-sleeve heater, 8-cooling blower.
Five. the specific embodiment:
Below in conjunction with Fig. 1 and Fig. 2 the extruder screw of the utility model oil temperature control is further described:
See Fig. 1, the extruder of oily temperature control screw rod is by reduction box 1, and screw rod 2 rotates shaft joint 3, sleeve 4, and oily circulating temperature controller 5, sleeve heater 7 and cooling blower 8 are formed.
See Fig. 2, screw rod 2 connects oily circulating temperature controller 5 by rotation shaft joint 3, by oil pipe 6 oil is imported in the screw rod 2, and the spill port by screw rod 2 flows back to oil in the oily circulating temperature controller 5, thereby forms circulation, makes the temperature of screw rod 2 controlled.
Claims (1)
1. the extruder screw of oily temperature control, comprise screw rod, the rotation shaft joint, oil pipe, oil circulating temperature controller, it is characterized in that: the extruder screw of described oily temperature control is imported screw rod from oily circulating temperature controller by oil pipe with oil by the rotation shaft joint, and makes oil flow back to oily circulating temperature controller formation circulation through the spill port of screw rod.
