Horizontal screw-type quantitative feeding devices for conventional single-screw and multi-screw extruders usually place a screw inside a cylinder, and feed plastic raw materials, stabilizers, fillers, and other powder raw materials such as flour from one side of the cylinder. By rotating the cylinder, it was supplied to the extruder through an open mouth at the tip of the cylinder.
In this case, especially if the rotational speed of the screw is slow, the raw material will become tight and fill the inside of the cylinder, forming a cylindrical block and falling from the cylinder mouth to the extruder supply port. Therefore, raw materials are supplied to the extruder intermittently, and surging occurs, making it impossible to obtain a homogeneous product and causing quality deterioration.

The present invention eliminates these drawbacks, and its purpose is to provide a horizontal screw-type quantitative feeding device for an extruder that enables smooth and continuous feeding of raw materials in a constant amount.

The horizontal screw-type quantitative feeding device for an extruder according to the present invention is a horizontal screw in which a rotating screw is disposed inside a cylinder, and the rotation of the screw supplies powder raw materials to the extruder through an opening at the tip of the cylinder. This feeding device is characterized in that a gate having a plurality of intersecting weirs made of wire is attached to the opening at the tip of the cylinder at right angles to the screw shaft.

The present invention will be explained below with reference to FIGS. 1 and 2 showing one embodiment. A screw 13 rotated by a drive source 12 such as an electric motor is arranged on the inner diameter side of the cylinder 11 placed horizontally.
Plastic raw materials and the like are inputted from a supply port 14 near the base end of the tube. This raw material is sent forward (to the left) by a screw 13, passes through a gate 15 attached to the opening at the tip of the cylinder 11, is divided into pieces, falls into a chute 16, and is supplied to an extruder (not shown) located below the chute 16. fed into the mouth.

押えることが必要である。 The gate 15 has a plurality of weirs 17 that intersect vertically and horizontally.If the width of the weirs 17 is wide, the resistance increases and heat is generated inside the cylinder 11. Therefore, the weirs 17 are made of thin piano wire or the like. It is necessary to have low resistance and suppress heat generation.

As explained above, the horizontal screw-type quantitative feeding device for an extruder according to the present invention has a simple configuration in which a gate having a plurality of intersecting weirs made of wire rods is attached to the opening at the tip of the cylinder, Even if it becomes a cylinder, it is subdivided by gates when it is extruded. Therefore, a constant amount of the raw material is supplied to the extruder continuously rather than intermittently, so that the product obtained by the extruder has the advantage of being homogeneous and improving in quality.
