Abstract
The utility model discloses a feeding device for a tubing extrusion line. The feeding device for the tubing extrusion line comprises a material storage bin, a sensor and a hopper, the sensor is arranged in a material discharging opening of the material storage bin, a material discharging opening of the hopper is communicated with a material feeding opening of the tubing extrusion line, and the sensor is connected with a controller which controls automatic feeding. The feeding device for the tubing extrusion line is accurate and stable in feeding flow control, the controller is simple in arrangement and operation, short time is required, and the feeding device for the tubing extrusion line is suitable for feeding control in the process of continuous production.
Description
Technical field
The utility model relates to a kind of feeding device, is specifically related to a kind of reinforced metering device for the tube extrusion line.
Background technology
In the production process of HDPE plastics solid wall pipe material, at first be that each required component of extruder is weighed, secondly be the component that every extruder needs is altogether mixed, be the material supply extruder hopper that will mix melt extrudes at last.Conventional way is that off-line carries out counterweight, namely determines the proportioning of major ingredient and auxiliary material, by the artificial stirring extruder hopper of packing into.Can cause so inaccurate such as weighing, batch mixing is inhomogeneous, particularly additive disperses the problems such as insufficient in the multicomponent batching, even can be because artificial batching too much cause the waste of raw material and the increase of cost of labor.
The structure of the characteristic of the fluctuation of extruder motor, plastics materials, screw barrel and the technique change in the extrusion all can affect extruding of tubing in the tube extrusion line, with regard to the characteristic aspect of material, in process of production, if it is stable that the flow of material can not keep, the impact that its result must be very large on the mass formation of product.Therefore, how effectively to control the stability of mass flow, accurately record and the mass flow of testing product and carry out corresponding measure with the Mi Chong of control product, namely adopt the automatic Weighing measure control to guarantee that the economic benefit of production line and product quality are extremely important in extrusion.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of stable simple feeding device that is used for the tube extrusion line of accurately controlling, arrange.
For solving the problems of the technologies described above, a kind of feeding device for the tube extrusion line of the utility model, comprise storage bin, sensor and hopper, described installation of sensors is in the discharging opening of storage bin, the feeding inlet of the discharging opening of described hopper and tube extrusion line, described sensor are connected with the controller of control auto feed.
Compared with prior art, the beneficial effect that the utlity model has is: the utility model directly records measured value from storage bin, reinforced flow precise control and stable, the simple time that only need extremely lack of the setting operation of controller; Bian gravity type sensor, rather than use volume metering, be applicable to the charging control in the continuous flow procedure.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the structural representation of a kind of feeding device for the tube extrusion line of the utility model.
The specific embodiment
As shown in Figure 1, a kind of feeding device for the tube extrusion line, comprise storage bin 1, sensor 2 and hopper 3, described sensor 2 is installed in the discharging opening of storage bin 1, the feeding inlet of the discharging opening of described hopper 3 and tube extrusion line, described sensor 2 are connected with the controller 4 of control auto feed.
In controller 4 setting values, the reinforced flow of reality in the sensor 2 Bian collection storage bins 1 feeds back to controller 4, again with setting value relatively, if actual value less than setting value, controller just increases the rotating speed of charger, otherwise just reduce the rotating speed of charger, thereby make actual approaching with setting value.The reinforced flow precise control of the utility model and stable, simple only need of the setting operation of controller is applicable to the charging control in the continuous flow procedure the extremely short time.
