Parallel twin screw side feeder

The lateral forced feeding device designed and manufactured by our company and matched with the twin-screw extruder is used for filling and reinforcing inorganic materials such as glass fiber, talc powder, carbonic acid and titanium dioxide in the production of twin-screw extrusion. The dosing device is dosed to the side feeding device by a quantitative feeder, and then forced into the twin-screw main body through a dedicated barrel and a constant gap twin screw. If the additive material is added from the main feed port by a conventional method, on the one hand, due to the different bulk density of the plurality of materials, especially when the powder is added, the layering of the powder is easy, and the composition of the finished product is uneven. On the other hand, the hardness of the added materials is mostly compared. High, solid, not plasticized, the addition of solids from the barrel will cause wear on the screw and barrel of the feed section. However, if the lateral feeding method is adopted, the filling material is added from the melting section of the material, and the filling material is wrapped and mixed by the molten material as soon as it enters the main machine, thereby avoiding the wear of the screw and the barrel, and reducing the friction caused by the friction. Energy waste, effectively increase production and production efficiency, and reduce production costs.

According to the customer's production experience, the use of our company's side feeding system, the amount of calcium carbonate can reach 550Kg / h, the amount of short fiber can reach 500 Kg / h, and improve the filling content accuracy. Taking the introduction of glass fiber as an example, the accuracy of the glass fiber content introduced by the long fiber is ±5%, and the short-cut glass fiber is introduced by the side feeding system, and the measured glass fiber content accuracy is ±2%. It can be proved that the side feeding system not only greatly increases the output of the main engine, but also reduces the energy consumption, reduces the wear, improves the life of the barrel screw, and prolongs the screw assembly.

The barrel of the new side feeder designed and produced by our company adopts the whole wear-resistant steel sleeve for the introduction of glass fiber material, which improves the wear resistance and prolongs the service life;

The screw of the side feeder abandoned the early design structure of the whole screw and the equal pitch, and adopted the structure of the mandrel plus the equal-gap fully-engaged thread block, adopting various pitches and building blocks to improve the forced conveying effect and ensure the side. Feeding accuracy and yield;

Moreover, more humanized structures have been added, such as observation holes at the spline sleeve, drawers for cleaning leaks, flat screw heads, height-adjusting brackets, and the like. Make it easier for users to use.
