Problems solved by technology

[0015] However, even in the push-in screw disclosed in Patent Document 4, the raw material tends to adhere to or remain on the inner wall of the bucket shell. In order to scrape off the raw material adhered to the inner wall of the shell, the push-in screw provided at both ends become an overload concern

Abstract

Disclosed is a push screw device wherein: each push screw is arranged such that each rotationally driving shaft is disposed along the same straight line when viewed from above; the bottom end position in the vertical direction of each screw blade is the same and the spiral winding direction of these screw blades is opposite for adjacent screw blades; two push screws disposed at the center of the arranged direction of the push screws are the center screws, and the rotation direction of the screw blades and the supply direction of the raw material is the same, when the section between each of the rotationally driving shafts that contain these center screws is viewed from above.

Description

technical field [0001] The present invention relates to a pressing screw device suitable for use in a roll forming machine for pressing a raw material mixed with a fine powder and a binder into a plate shape, for example, and a roll forming machine equipped with the pressing screw device. [0002] This application claims the priority based on Japanese Patent Application No. 2010-095648 for which it applied to Japan on April 19, 2010, and uses the content here. Background technique [0003] Conventionally, as an apparatus for press-molding granulated raw materials obtained by mixing fine powder and a binder, a briquetting machine (Roll block forming machine) has been used. briquetting machine such as Figure 4 Shown is a forming roll 104 having a pair of fixed rolls 102 and movable rolls 103 having independent rotation axes. The fixed roller 102 is arranged in a fixed position. On the other hand, the movable roller 103 receives a predetermined pressure from the hydraulic cy...
