Abstract

The invention discloses a feeding device of a plastic extruder, relating to the technical field of plastic extruders. The feeding device comprises a hopper, wherein the hopper is communicated with a cylinder of the plastic extruder through a horizontally-arranged feeding cylinder; the upper part of one end of the feeding cylinder is connected with the hopper, and the lower part of the other end of the feeding cylinder is connected with the cylinder; the feeding cylinder is internally provided with a feeding screw driven by a motor; and a vibrating motor is arranged outside the hopper. Compared with the prior art, the feeding device is uniform in feeding and stable in product quality.

Description

Plastic extruder feed arrangement
Technical field
The present invention relates to plastic extruder technical field, especially a kind of plastic extruder feed arrangement.
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 feed arrangement, this device can solve existing plastic extruder feed arrangement and exist reinforced uneven, causes unstable product quality problem.
In order to solve the problem, the technical solution used in the present invention is: this plastic extruder feed arrangement comprises hopper, be connected by the feed cylinder of a horizontally set between described hopper and the machine barrel of plastic extruder, the top of described feed cylinder one end is connected with described hopper, the bottom of the other end connects described machine barrel, is provided with by motor-driven feeding spiro rod in described feed cylinder; The outer setting of described hopper has vibrating motor.
In the technical scheme of above-mentioned plastic extruder feed arrangement, technical scheme can also be more specifically: the top of described hopper is provided with weighing hopper, and the bottom of described weighing hopper is provided with weight sensor, and the outlet of described weighing hopper is positioned at directly over described hopper; The top of described weighing hopper is provided with a material storing box, and the bottom of described material storing box has an outlet and is positioned at conveying pipeline directly over described weighing hopper; The outlet of described conveying pipeline is provided with the first magnetic valve, and the outlet of described weighing hopper is provided with the second magnetic valve.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect:
1, weighing hopper is set and accurately controls feeding quantity, and by the cooperation of helical blade and charging line, accurately controlled the charging rate of extruder by the rotating speed controlling rotating shaft, thus make evenly reinforced, improve 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.
Accompanying drawing explanation
Fig. 1 is the structural representation of this plastic extruder feed arrangement.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the invention will be further described:
Plastic extruder feed arrangement shown in Fig. 1 mainly comprises hopper 3, feed cylinder 6, feeding spiro rod 7 and motor 5, between the machine barrel 8 of feed cylinder 6 horizontally set and hopper 3 and plastic extruder, the top of feed cylinder 6 one end offers the import be connected with the discharging opening of hopper 3, the bottom of feed cylinder 6 other end offers the outlet be connected with the charging aperture of machine barrel 8, hopper 3 is connected with machine barrel 8 by feed cylinder 6, feeding spiro rod 7 is provided with in feed cylinder 6, helical blade 7-1 on feeding spiro rod 7 and the inwall matched in clearance of feed cylinder 6, one end of feeding spiro rod 7 is stretched out feed cylinder 6 and is connected with motor 5, feed cylinder 6 is provided with sealing device near one end of motor 5, and the other end is closed, in order to prevent material from tying arch, the material in hopper 3 can be entered in feed cylinder 6 more swimmingly, have vibrating motor 4 in the outer setting of hopper 3.Preferably, in order to accurately control feeding quantity, above hopper 3, be also provided with weighing hopper 2, the bottom of weighing hopper 2 is provided with weight sensor 2-2, and the outlet of weighing hopper 2 is positioned at directly over hopper 3; The top of weighing hopper 2 is also provided with a material storing box 1, and the bottom of material storing box 1 has an outlet and is positioned at conveying pipeline 1-1 directly over weighing hopper 2; The outlet of conveying pipeline 1-1 is provided with the first magnetic valve 1-2, and the outlet of weighing hopper 2 is provided with the second magnetic valve 2-1, and the first magnetic valve 1-2, the second magnetic valve 2-1, vibrating motor 4 and motor 5 are all electrically connected with controller.
During work, raw material is poured in material storing box 1, open the first magnetic valve 1-1, raw material in material storing box 1 drops down onto in weighing hopper 2 by conveying pipeline 1-1, when weight sensor 2-2 bottom weighing hopper 2 senses that the raw material in weighing hopper 2 reaches scheduled volume, weight sensor 2-2 sends signal to controller, control the first magnetic valve 1-2 by controller to close, open the second magnetic valve 2-1 simultaneously, Vibration on Start-up motor 4 and motor 5, raw material in weighing hopper 2 falls in hopper 3, material in hopper 3 enters continuously in feed cylinder 6 under the effect of vibration of vibrating motor 4, material is constantly pushed to the other end along the feeding spiro rod 7 rotated, finally enter in machine barrel 8 from the outlet of the other end.
