AI Technical Summary

Technical Problem

The existing dustproof rack's limiting structure is prone to sealing failure due to inertial over-winding, which cannot effectively prevent dust from entering the machine tool.

Method used

A machine tool dustproof frame with a roller shutter cover was designed, which includes a winding drive mechanism, a guiding mechanism, a self-cleaning mechanism, and a limiting mechanism to ensure the smoothness and reliability of the roller shutter cover during unfolding and retraction, and to achieve precise positioning through the limiting mechanism to prevent over-winding.

Benefits of technology

It effectively blocks dust from entering the machine tool, reduces wear, extends the machine tool's lifespan, keeps the roller shutter cover clean, ensures dust prevention, prevents the roller shutter cover from shifting or over-rolling, and reduces friction noise.

Abstract

This utility model discloses a machine tool dustproof frame with a roller shutter cover, relating to the field of dustproof frame technology. It aims to solve the technical problem that the limiting mechanism relies solely on the sliding cooperation between the snap-fit ​​block and the limiting groove, which easily leads to sealing failure due to inertial over-winding. The key technical points are: it includes a frame, with two dustproof support plates on the top of the frame. A roller shutter cover for dust prevention is positioned above the two dustproof support plates. A winding drive mechanism is provided on the roller shutter cover. Several sets of guide mechanisms are provided on opposite sides of the roller shutter cover, respectively disposed on the surfaces of the two dustproof support plates. A self-cleaning mechanism is provided above the roller shutter cover. A limiting hole is also provided on each opposite side of the roller shutter cover. A limiting mechanism for abutting the limiting hole is provided on each of the two dustproof support plates. The purpose of this utility model is to provide a machine tool dustproof frame with a roller shutter cover.
