Closed link transportation device driven by permanent magnet linear motor

Abstract

The invention discloses a closed link transportation device driven by a permanent magnet linear motor, which comprises an even number of chain links which are connected with each other end to end, wherein every two chain links are connected with each other through a connection lock catch, so as to form a closed transportation link; each chain link is fixedly connected with a runner of a linear motor; a plurality of runners are sleeved on one or more stators of the linear motor; a permanent magnet is arranged between each stator and each runner; the polarities of permanent magnets on adjacent runners are opposite; and each chain link is supported through a transportation rail, and can move freely on the transportation rail. According to the invention, a long chain is driven by the double side permanent magnet coreless permanent magnet linear motor, so as to disperse driving power, overcome centralized tension accumulation as well as limitation and adverse effects caused by the centralized tension accumulation when a chain wheel driving manner is adopted, improve the maintainability and the reliability of a product, prolong the service life of the product, and can infinitely extend the length of the link.

Description

technical field [0001] The invention relates to a tobacco machine, in particular to a closed link transport device driven by a permanent magnet linear motor. Background technique [0002] In traditional tobacco machinery, a rotating motor is generally used to drive the sprocket to drive the logistics conveyor chain. Due to the concentrated accumulation of motion friction of each chain link, the tension of the chain links near the sprocket is huge, which often causes the chain to be elongated and damaged, and increases the maintenance workload, thereby limiting the length of the chain driven by a single sprocket. In addition, the mechanism of using the rotating motor to drive the sprocket is relatively complicated. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a closed link transport device driven by a permanent magnet linear motor, which can reduce the chain link tension of the closed link transport device and...
