Micro rails for large printers

Abstract

The invention provides a miniature guiding rail for a large-scale printer. The miniature guiding rail comprises an arc-shaped plate, a sliding plate, a sliding groove, a base, lug bosses, a plastic holding frame, heat-dissipating through holes, a plurality of steel balls, a supporting rod, a sliding rail, a groove, an insertion pile, a sliding block, a limiting block, a flange bearing, an insertion block, a gear rack, a gear, a rotating shaft, a bearing, a rotating plate and screws, wherein the sliding groove is formed in the base; inward-concave first concave strips are correspondingly arranged on the left and right side walls of the interior of the sliding groove; the plastic holding frame is arranged in the sliding groove; the lug bosses are correspondingly mounted on the left and right sides of the bottom of the plastic holding frame, and positioned on the sliding groove; the lower bottom surfaces of the lug bosses cling to but are not fixedly connected with the upper bottom surface of the sliding groove; the steel balls are correspondingly mounted on the left and right sides of the plastic holding frame; and the sides, close to the base, of the steel balls are embedded in the first concave strips in the base. The miniature guiding rail provided by the invention has the advantage that the moving distance of the sliding plate can be changed.

Description

technical field [0001] The invention relates to a miniature guide rail for a large printer and belongs to the technical field of miniature guide rails. Background technique [0002] The inkjet head of a large printer needs to move up and down continuously. Generally, the inkjet head and the sliding plate of the linear slide rail are installed together, and the inkjet head moves up and down with the help of the sliding plate. A rolling guide, which uses steel balls to perform infinite rolling cycles between the sliding plate and the guide rail, so that the load platform can easily move linearly with high precision along the guide rail, and generally a limit plug is set between the sliding plate and the chute Stakes to limit the travel distance of the sliding panels. The stakes in the prior art are fixed structures, and the moving distance between the sliding plate and the chute cannot be changed. In order to solve the above difficulties, it is necessary to develop a micro-r...
