Description
Technical field
The present invention relates to plastic extruder technical field, especially a kind of plastic extruder measurement charging 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, and then control feeding quantity by the cutting device of feed hopper bottom, this technical scheme exists following deficiency: feeding quantity is inaccurate, charging rate is uneven, unstable product quality.
Summary of the invention
The object of this invention is to provide a kind of plastic extruder measurement charging device, this device can solve existing plastic extruder measurement charging device and exist reinforced inaccurate, uneven, causes unstable product quality problem.
In order to solve the problem, the technical solution used in the present invention is: this plastic extruder measurement charging device comprises hopper and hopper cover, described hopper cover offers charging aperture, the bottom of described hopper has the charging line erect and arrange, and described charging line is connected with the machine barrel of plastic extruder; 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 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 communicated with by the charging aperture of pipeline with described hopper cover; 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.
In the technical scheme of above-mentioned plastic extruder measurement charging device, technical scheme can also be more specifically: in described hopper, be provided with many shift forks on the top of described rotating shaft.
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.
