Abstract
The utility model relates to plastic weaving machinery, in particular to a vacuum exhaust drawing mill which is improved on the basis of an original drawing mill, and is characterized in that an extruding screw rod is manufactured to be in a two-section plasticization extruding structure; a vent hole is arranged in the middle of a cylinder; one end of a suction pipe is fixedly connected with the vent hole in the cylinder, and the other end of the suction pipe is fixedly connected with an air suction port of a vacuum pump; an exhaust pipe is fixedly connected with a vent hole of the vacuum pump; and one end of a cooling pipe is connected with the vacuum pump, and the other end of the cooling pipe is connected with a water tank. As the extruding screw rod is designed to be in the two-section plasticization extruding structure, and the vent hole is arranged in the cylinder, large amount of gas generated by regenerated plastic granules during the heating, plasticizing and extruding process at a first plasticization extruding section of the extruding screw rod is discharged from the vent hole in the cylinder by negative pressure generated by the vacuum pump, and a second plasticization extruding section performs uniform plasticization extruding on melted plastic again and manufacture the plastic into ribbon-like filaments smoothly through a tee joint and a die head, so that the recycling problem of the recovered plastic is solved, environmental pollution is avoided, and renewable resources can be utilized.
Description
[technical field]
The utility model relates to plastic knitting machinery, particularly a kind of vacuum exhaust wire drawing machine.
[background technology]
After must causing particle, the waste or used plastics that reclaims at present could utilize once more; Heat during because of waste plastic granulation the fusing after to cool off fast through supercooled water; But the steam that when cooling off fast, produces produces bubble and can't separate out in particle; And its extrusion screw rod of plastic-wire drawing machine of manufacturing both at home and abroad at present and use all adopts one section plasticizing to extrude; Machine barrel is not provided with steam vent, can not use the regenerated plastics particle that contains more bubble and moisture to draw flat filament, if the untimely reclaiming utilization of a large amount of waste plastics will inevitably cause the environmental pollution and the wasting of resources.
[utility model content]
The utility model improves on the basis of former structure of wire drawing machine to above-mentioned deficiency, and a kind of vacuum exhaust wire drawing machine that can utilize 100% regenerated plastics particle to draw flat filament is provided.
The technical scheme of the utility model is improved on the basis of former wire drawing machine and is realized, its structure comprises motor 1, reduction box 2, extrusion screw rod 3, machine barrel 4, threeway 10, die head 11, frame 12; It is characterized in that extrusion screw rod 3 processes two sections plasticizings and extrude structure, machine barrel 4 middle parts are shaped on steam vent, and air intake duct 5 one ends are fixedly connected with steam vent on the machine barrel 4, and the other end is fixedly connected with the air entry of vavuum pump 9; Blast pipe 6 is fixedly connected with the exhaust outlet of vavuum pump 9, and cooling tube 8 one ends are connected with vavuum pump 9, and the other end is connected with water tank 7.
The characteristics of the utility model are to extrude structure because extrusion screw rod is designed to two sections plasticizings; Steam vent is set on machine barrel again; The negative pressure that is produced by vavuum pump the steam vent of a large amount of gases from machine barrel that the regenerated plastics particle is produced in the extrusion screw rod first plasticizing extruding zone heating plasticizing extrusion emits gas; The second plasticizing extruding zone is the plastics that melted evenly to be plastified to extrude through threeway and die head once more process flat filament smoothly; Solve the problem of utilizing again after the waste plastics recovery, neither can cause environmental pollution can utilize regenerated resources again.

Fig. 3 is the structural representation of machine barrel.
[specific embodiment]
Further specify embodiment below in conjunction with accompanying drawing with optimal way.
With reference to Fig. 1,1-motor, 2-reduction box, 3-extrusion screw rod, 4-machine barrel, 5-air intake duct, 6-blast pipe, 7-water tank, 8-cooling tube, 9-vavuum pump, 10-threeway, 11-die head, 12-frame.As shown in the figure, motor 1 is packed on the frame 12, is in transmission connection with reduction box 2.Machine barrel 4 is packed on the casing of reduction box 2, and extrusion screw rod 3 ends are fixedly connected again with the output shaft of reduction box 2 and cooperate with machine barrel 4 activities.Air intake duct 5 one ends are fixedly connected with steam vent on the machine barrel 4, and the other end is fixedly connected with the air entry of vavuum pump 9.Blast pipe 6 is fixedly connected with the exhaust outlet of vavuum pump 9, and cooling tube 8 one ends are connected with vavuum pump 9, and the other end is connected with water tank 7.
With reference to Fig. 2, the 3-extrusion screw rod.As shown in the figure, the A section is the first plasticizing extruding zone, and the B section is the second plasticizing extruding zone.
With reference to Fig. 3, the 4-machine barrel.As shown in the figure, C is a charge door, and D is a steam vent.
During the utility model work; Motor 1 drives reduction box 2 and makes extrusion screw rod 3 rotations; The plastic pellet that gets into from machine barrel 4 charge doors is pushed forward at the first plasticizing extruding zone; Plastic pellet begins fusing under the extruding of machine barrel that heats 4 and extrusion screw rod 3; The negative pressure that a large amount of gases that produce during the plastic pellet fusing produce when the steam vent of machine barrel 4 is worked by vavuum pump 9 is discharged by force, and the plastics after the fusing push even plasticizing through the second plasticizing extruding zone more once more, extrude smooth drawing flat filament through threeway 10 through die head 11.
