Description
Technical field
The present invention relates to plastic extruder technical field, especially a kind of plastic extruder feeding device.
Background technology
The processing and forming of plastics is the important steps making plastic raw materials be converted into goods, extrusion molding is one of important forming method of plastics processing, the method refers to that material is by the effect between the barrel of plastic extruder and screw rod, limit is by thermoplastification, while by screw rod pushed forward, after being forced through head, made a kind of processing method of various goods by cooling and shaping and cutter sweep.Plastic extruder is commonly called main frame in plastic extruding forming equipment, it is made up of extrusion system, transmission system and heating and cooling system, and the hopper be arranged on above extruder barrel is the feeding device of extrusion system, it is directly for machine barrel provides raw materials for production.Existing hopper only arranges cutting device in bottom, to regulate and to block stream, time reinforced, pour in hopper after raw material is mixed, raw material relies on self gravitation to enter in barrel, then control feeding quantity by the cutting device of feed hopper bottom, there is following deficiency in this technical scheme: charging rate is uneven, unstable product quality.
Summary of the invention
The object of this invention is to provide a kind of plastic extruder feeding device, this device can solve existing plastic extruder feeding device, and to there is charging rate uneven, causes unstable product quality problem.
In order to solve the problem, the technical solution used in the present invention is: this plastic extruder feeding device comprises hopper and hopper cover, described hopper cover offers charging aperture, and the bottom of described hopper has the charging line erect and arrange, and the port of export of described charging line is provided with magnetic valve; Described hopper cover is provided with motor, the output shaft of described motor is arranged down, described output shaft is connected with the rotating shaft stretching into described charging line, helical blade is installed with, the outer rim of described helical blade and the inwall matched in clearance of described charging line in described rotating shaft bottom and described charging line; The top of described rotating shaft is provided with many shift forks.
In the technical scheme of above-mentioned plastic extruder feeding device, technical scheme can also be more specifically: the inner chamber upper angled of described hopper is provided with screen cloth, described charging aperture corresponds to the higher one end of described screen cloth, offers residue-removing opening with cover at the sidewall of described hopper in one end that described screen cloth is lower.
Further, the lower end of described residue-removing opening is provided with the support swash plate stretched in described hopper, and the bottom surface of described support swash plate and described screen cloth is inconsistent.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect:
1, the present invention is by the cooperation of helical blade and charging line, is accurately controlled the charging rate of extruder by the rotating speed controlling rotating shaft, thus makes evenly reinforced, improves the stability of product quality.
2, arranging shift fork can make raw material be easy to enter charging line, avoids the raw material in charging line to occur being interrupted.
3, screen cloth is set and can screens out larger raw material, avoid raw material to occur jam in charging line.
4, residue-removing opening is set and can be convenient to cleaning by the raw material screened out.
Accompanying drawing explanation
Fig. 1 is the structural representation of this plastic extruder feeding device.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the invention will be further described:
Plastic extruder feeding device shown in Fig. 1 mainly comprises hopper 1, hopper cover 2, motor 3, rotating shaft 5 and screen cloth 4, hopper 1 bottom of taper has the charging line 1-1 erectting and arrange, charging line 1-1 is connected with the machine barrel 9 of plastic extruder, at the port of export of charging line 1-1, magnetic valve 8 is installed, for blocking feeding; The inner chamber upper angled of hopper 1 is provided with screen cloth 4, residue-removing opening 1-2 with cover is offered in one end that screen cloth 4 is lower at the sidewall of hopper 1, be provided with the support swash plate 1-3 stretched in hopper 1 in the lower end of residue-removing opening 1-2, the bottom surface of this support swash plate 1-3 and screen cloth 4 is inconsistent; One end that hopper cover 2 corresponds to screen cloth 4 higher offers charging aperture 2-1, the middle part of hopper cover 2 is provided with motor 3, the output shaft of motor 3 is arranged down, output shaft is connected with the rotating shaft 5 stretched into through screen cloth 4 in charging line 1-1, inner chamber on the top of rotating shaft 5 in hopper 1 is provided with many shift forks 6, many shift forks 6 are obliquely installed down, and these shift fork 6 apportions become upper and lower two circles; Helical blade 7 is installed with, the outer rim of helical blade 7 and the inwall matched in clearance of charging line 1-1 in rotating shaft 5 bottom and charging line 1-1.
Raw material is poured in hopper 1 from charging aperture 2-1, the major part of raw material tumbles feed hopper 1 bottom downwards through screen cloth 4, larger raw material then slides to for 4 times along screen cloth and supports swash plate 1-3, starter motor 3, motor 3 drives rotating shaft 5 to rotate, the rotating shaft 5 of rotating makes shift fork 6 constantly stir raw material, raw material is made continuously smoothly to enter in charging line 1-1, raw material in charging line 1-1 is along helical blade 7 constantly conveying downwards, when raw material arrives charging line 1-1 lower end, magnetic valve 8 is opened, and raw material at the uniform velocity enters in machine barrel 9 from the port of export of charging line 1-1.
