Long straight cylindrical helical spring type powder conveying piece

Abstract

The invention discloses a long straight cylindrical helical spring type powder conveying piece, which relates to the technical field of parts of a duplicating machine. The main parts for conveying the carbon powder in the conventional duplicating machine are all long bolt type parts, based on multiple helical surfaces outside the body of the bolt, each long bolt type part rotates around an axis to push the powder and conveys the powder in a powder box to a further powder utilization place. But the long bolt type parts also have too many defects. The invention uses a long straight cylindrical helical spring, which has large length-width ratio and rectangular cross section, as the powder conveying piece, wherein the plane of a long side of the rectangular cross section of the belt material is similar to the helical surface on the long bolt structure, when the helical spring rotates, the powder conveying piece has the same function of pushing and conveying the powder, but the powder conveying piece has a simpler structure, is very easy to produce and process, and can realize high-speed manufacturing, moreover, a hollow inner bore has no bolt body, the powder conveying piece can be more light, the material consumption is relatively low, and the cost (including manufacturing) is reduced obviously.

Description

[0001] technical field [0002] The invention discloses a long straight cylindrical helical spring type powder conveying part, which relates to the technical field of copier parts. Background technique [0003] The structure of the main parts used to transport and provide toner powder in the existing copiers (including some printers) is a long screw type, relying on the many helicoids arranged uniformly outside the screw body to transfer the inner cavity of the matching copier tube to the circle The helical surface rotates around the screw axis in the tube hole to produce a pushing effect, and the powder is transferred from the powder box to a far away powder place. However, the long screw with the helical surface is difficult to manufacture, the material consumption is relatively large, and the cost is relatively high. Tall and relatively heavy. Contents of the invention [0004] The purpose of the present invention is to provide a long straight cylindrical helical s...
