Abstract
The utility model relates to an inorganic filler side feeding device for screw rod extruding machine. The side wall of the raw material non-heating section of the screw extruder is connected with the discharge port of the filler feeding machine, and the filler and the master batch fed from the feed port of the screw extruder are mixed at the section. The utility model discloses can be directly pass through the feeding machine with the powder material and raw materials (synthetic resin and other auxiliaries) homogeneous mixing in the feed cylinder of screw rod extruding machine, avoid the use of dispersant, reduce mixing time, reduce manufacturing cost.
Description
Technical Field
The utility model belongs to the technical field of the plastics processing, a granulation equipment is related to, especially an inorganic filler side feeding device for screw rod extruding machine.
Background
In the production process of modified plastics, according to the performance requirements of products, inorganic fillers are usually required to be added, and the inorganic fillers are usually powder fillers, such as talcum powder, calcium carbonate, mica, barium sulfate and the like, so that the rigidity of the materials is improved, and the cost is reduced. At present, a certain amount of dispersing agent (such as white oil) is generally added in a mode of adding the inorganic filler, and the inorganic filler, the synthetic resin and other auxiliaries are mixed by a mixer.
Disclosure of Invention
An object of the utility model is to overcome prior art's weak point, provide an effectively reduce raise dust, reduce cost's an inorganic filler side feeding device for screw rod extruding machine.
The utility model provides a technical scheme that technical problem adopted is:
an inorganic filler side feeding device for a screw extruder is characterized in that the side wall of a raw material non-heating section of the screw extruder is connected with a discharge port of a filler feeding machine, and a filler and a master batch fed from a feed port of the screw extruder are mixed at the section.
Furthermore, the unheated section is located adjacent to the feed port of the screw extruder in a second section of the screw extruder.
Moreover, the screw extruder is a twin-screw extruder.
Moreover, the filler feeder is a screw feeder.
And a frequency converter for controlling the rotating speed of the filler feeder is arranged on a driving motor of the filler feeder.
The utility model has the advantages that:
1. the utility model discloses can be directly pass through feeding machine and masterbatch homogeneous mixing in screw rod extruding machine's feed cylinder with powder material, avoid the use of dispersant, reduce mixing time, reduce the running cost.
2. The utility model discloses a motor of feeding machine is inverter motor, can control the add volume that adds the filler through the rotational speed of control screw rod, guarantees the performance of product.

Fig. 1 is a schematic structural view of the present invention;
fig. 2 is a sectional view taken along line a-a in fig. 1.
Detailed Description
The present invention will be described in further detail with reference to the following embodiments, which are illustrative, not restrictive, and the scope of the invention should not be limited thereto.
An inorganic filler side feeding device for a screw extruder is characterized in that the side wall of a raw material non-heating section of the screw extruder 1 is connected with a discharge port of a filler feeding machine 2. The filler and the master batch fed from the feed inlet 3 of the screw extruder are mixed in the section and then enter the heating section together for heating and melting.
The unheated section is located near the feed inlet of the screw extruder, particularly in the second section of the screw extruder.
The type of the filler feeder is a single screw or a double screw, and a frequency converter is arranged on a motor of the filler feeder and used for controlling the rotating speed of the filler feeder.
When the feeding device is used, the filler feeding machine is started, the frequency converter is adjusted according to the adding amount of the inorganic filler, the rotating speed of the screw extruder is enabled to reach the preset rotating speed, the screw extruder is started, the master batch enters the screw extruder, the inorganic filler is placed into the feeding hopper, and the feeding cover is covered. The inorganic filler enters the second cylinder of the screw extruder through the filler feeder to be mixed, and because the second cylinder is not heated yet, the master batch and the inorganic filler advance in the cylinder in a rotating manner and are uniformly mixed with the inorganic filler before the master batch is melted, the uniformity of the product is ensured.
The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, many variations and modifications can be made without departing from the inventive concept, and these are all within the scope of the present invention.
