Rotary conveying mechanism

Technical Field

The invention belongs to the field of mechanical devices and transportation, and particularly relates to a rotary conveying mechanism.

Background

At present, a conveying and conveying line of materials is generally fixed, for some materials with larger volume or heavier weight, because the materials are inconvenient to rotate, a common conveying mechanism mostly realizes the steering of products through a facility of an arc-shaped line, but in order to keep the stability of the products, the curvature radius of an arc-shaped conveying track is generally larger, the occupied space is occupied, and the situation that the steering angle is larger is difficult to realize. There is therefore a need for a conveyor mechanism that facilitates the turning of the transfer rail. Prior art for example chinese patent CN102344031A discloses a revolving stage conveyer, set up in material delivery track, connect other delivery tracks, its characterized in that includes: a base; a roller bracket arranged above the base and a plurality of rollers arranged in parallel; the rotary support bearing is arranged between the base and the roller bracket; the driving device is eccentrically arranged on one side of the rotary supporting bearing and drives the inner wheel of the rotary supporting shaft to rotate through the driving gear, so that the roller bracket and the roller connected with the inner wheel are driven to rotate.

However, the above-mentioned device is not suitable for large-volume objects, especially for high-quality materials, and has a limited range of use; the materials rotate on the roller along with the driving equipment, the position is easy to deviate, the conveying is unstable, and the precision is poor; the material rotates after the upper roller and waits to be output, and the output efficiency is lower.

Disclosure of Invention

Aiming at the defects of the prior art, the invention particularly provides the rotary conveying mechanism which has the advantages of wide application range, stable conveying, high conveying precision and high efficiency.

In order to achieve the purpose, the technical scheme of the invention is as follows:

a rotary conveying mechanism is arranged in a material conveying track and comprises a rack, a rotary shaft vertically penetrates through the middle of a rack platen of the rotary conveying mechanism, a bearing is arranged between the rotary shaft and the rack platen, and the rotary shaft is driven to rotate by a rotary shaft driving piece; the top end of the rotating shaft is horizontally connected with a turntable, and a plurality of rotating material racks for bearing materials are hung on the lower end face of the turntable at intervals in the circumferential direction; and a material pulling component for pulling materials out of the rotary material rack is arranged below one rotary material rack, and the bag pulling component is fixed on the machine frame bedplate.
