Feeding quantity and charging rate for the ease of the control extruder; Optimized technical scheme also has; On said controller, be connected with display, control button and/or knob; Said display is used to show the feeding quantity and the charging rate of extruder, and said control button and/or knob are used to control the feeding quantity and the charging rate of extruder.
For the ease of the wall thickness according to feeding quantity control extruder basis pipe fitting, optimized technical scheme also has, and also is connected with plastic tube wall thickness detecting sensor at said controller, and said sensor is used to detect the wall thickness of extruder extrusion plastic pipe.
In order to make the smooth and easy difficult obstruction of discharging, optimized technical scheme also has, and said support is connected with said machine barrel is vertical, or tilts to connect.
In order to remove impurities in raw materials, optimized technical scheme also has, and between said loading hopper and material mouth, is provided with filter screen.
In order to remove the impurity of iron filings class in the raw material, optimized technical scheme also has, and described filter screen has two-layer, is provided with magnet on the one deck in said two-layer filter screen.
The advantage and the beneficial effect of the utility model are: the fully automatic culculating feeding device of this plastic tube extruder can be controlled the feeding quantity of extruder exactly; Thereby the tube wall thickness that extruder is extruded is even; Steady quality; Both can improve the quality of products, can save raw material again, can also realize the full-automation that raw material adds.

The specific embodiment
Below in conjunction with accompanying drawing and embodiment, the specific embodiment of the utility model is further described.Following examples only are used for more clearly explaining the technical scheme of the utility model, and can not limit the protection domain of the utility model with this.
Like Fig. 1, shown in 2, the utility model is a kind of fully automatic culculating feeding device of plastic tube extruder, and this device comprises support 1; Be provided with backgauge plug 2 at the top of said support 1; Side at said support 1 is provided with machine barrel 3, and the inside of said machine barrel 3 is connected with the inside of support 1, and an end of said machine barrel 3 is fixed on the support 1 through machine barrel flange 4; The other end at said machine barrel 3 is provided with stepper motor 5; Set inside at said machine barrel 3 has feeding spiro rod 6, and an end of said feeding spiro rod 6 links to each other with the output shaft of stepper motor 5, and said machine barrel 3 is provided with loading hopper 7; The material mouth 8 of said loading hopper 7 is connected with the inside of said machine barrel 3, and 8 places are provided with LOAD CELLS 10 at said material mouth.
Reinforced for the mixing that is fit to different material in the utility model, embodiment preferred is, said support 1, backgauge plug 2 and machine barrel 3 respectively have two covers.
For the ease of the feeding quantity and the charging rate of control extruder, embodiment preferred also has in the utility model, and said stepper motor 5 is connected with the output of controller 11, and said LOAD CELLS 10 is connected with the input of said controller 11 through line.
In the utility model for the ease of control extruder feeding quantity and charging rate; Embodiment preferred also has; On said controller 11, be connected with display 12, control button and/or knob 13; Said display 12 is used to show the feeding quantity and the charging rate of extruder, and said control button and/or knob 13 are used to control the feeding quantity and the charging rate of extruder.
For the ease of the wall thickness according to feeding quantity control extruder basis pipe fitting, embodiment preferred also has, and also is connected with plastic tube wall thickness detecting sensor at said controller in the utility model, and said sensor is used to detect the wall thickness of extruder extrusion plastic pipe.
In order to make the smooth and easy difficult obstruction of discharging, embodiment preferred also has in the utility model, said support 1 and said 3 vertical connections of machine barrel, or tilt to connect.
In order to remove impurities in raw materials, embodiment preferred also has in the utility model, between said loading hopper 7 and material mouth 8, is provided with filter screen 14.
