Pneumatic engaging and disengaging device for overhead cigarette carton conveying line

Abstract

The invention provides a pneumatic engaging and disengaging device for an overhead cigarette carton conveying line. The pneumatic engaging and disengaging device is sleeved on a main shaft through a steel sleeve, and comprises a plastic annular cylinder, a plastic movable gear and a plastic fixed gear, wherein the plastic annular cylinder is assembled on the steel sleeve through a big cylinder bearing and a small cylinder bearing; a plastic chain wheel is assembled on the steel sleeve through a chain wheel bearing; the plastic fixed gear is assembled on the plastic chain wheel and positioned on one side of the plastic annular cylinder; the plastic movable gear is positioned in the plastic fixed gear and contacted with the big cylinder bearing; a spring is positioned in the plastic movable gear and connected with one end of a spring head; the other end of the spring head is pressed against the chain wheel bearing; a forward buffer device is positioned in the plastic chain wheel; and a backward buffer device is positioned in the plastic fixed gear. By adopting a pure mechanical mode, the device has the advantages of high transfer force of single-way engagement and disengagement, high torque, no electromagnetic noise, no need of electric wire, no influence of current and voltage and capability of improving weather resistance, stability and greatly prolonging service life.

Description

Technical field: [0001] The invention relates to the field of factory automation logistics elevated conveying machinery and equipment, in particular to a pneumatic clutch device used on the elevated conveying line of tobacco rods. Background technique: [0002] In the production line of the existing cigarette factory, the cigarettes must be transported through the elevated conveyor line. In order to ensure the conveying speed, a set of elevated conveyor lines contains multiple cigarette conveyor belts. The existing conveyor belts are all It is composed of multiple chain plate bases connected in series through bolts, and then driven by a main shaft to convey. In this way, when a certain conveyor belt fails during the transportation process, the conveyor belt must be stopped for maintenance. At present, a set of electromagnetic clutches is installed on each conveyor belt for separate clutching. The structure of this type of scheme is complex and the cost is high, and the elect...

[0002] In the production line of the existing cigarette factory, the cigarettes must be transported through the elevated conveyor line. In order to ensure the conveying speed, a set of elevated conveyor lines contains multiple cigarette conveyor belts. The existing conveyor belts are all It is composed of multiple chain plate bases connected in series through bolts, and then driven by a main shaft to convey. In this way, when a certain conveyor belt fails during the transportation process, the conveyor belt must be stopped for maintenance. At present, a set of electromagnetic clutches is installed on each conveyor belt for separate clutching. The structure of this type of scheme is complex and the cost is high, and the electromagnetic clutches are often overloaded and burned due to unstable current and voltage.
