The roll shafts 2 are erected on the sliding rails 12, and the conveying direction is the same as that of the production line, so that materials are connected and conveyed between two adjacent conveyor stations. Specifically, when the maintainer needs to pass through the assembly line, the assembly line is temporarily closed through the switch, and then the roller shaft 2 is pushed to enable the sliding rail 12 to retract, so that the channel is opened, and the maintainer can conveniently pass through the channel.
Compared with the prior art, the embodiment of the invention can complete opening and closing of the channel and the gap through simple telescopic motion of the sliding rail 12, has short motion stroke and linear motion, and has lower requirement on the size of an external space. Meanwhile, compared with the closing of the traditional folding cylinder, the push-pull mechanism 1 provided by the embodiment of the invention has a simpler structure and is convenient to install. And the failure rate of the embodiment of the invention is linearly reduced due to the double simplification of the motion stroke and the mechanical structure, thereby effectively ensuring the smooth production.
