Technical Field

The invention belongs to the technical field of tobacco equipment, and particularly relates to a novel side push plate guide mechanism device based on a cigarette packet turnover machine.

Background

The side push plate guide mechanism is an important component of a cigarette packet overturning machine, the existing guide mechanism is matched with a linear bearing seat through a cylindrical guide rod to play a role in guiding and positioning, in order to prevent the cigarette packet from shifting and sliding off in the overturning process of the overturning machine, a side push plate is connected and fixed on a left linear bearing seat and a right linear bearing seat which are parallel through a U-shaped connecting plate, and under the driving of a push plate cylinder, the linear bearing seats move back and forth on the cylindrical guide rod to drive the side push plate to stretch out and draw back to realize the function of clamping and fixing the position of the cigarette packet; in the production process, due to the fact that the stretching synchronism of the left air cylinder and the right air cylinder of the side push plate is poor, the friction force between the straight bearing seat and the cylindrical guide rod is not balanced when the straight bearing seat moves on the guide rod, the surface of the straight bearing and the surface of the cylindrical guide rod are damaged, the surface of the guide rod is seriously abraded after the operation time is long, the stretching process of the side push plate is blocked, the service life of the bearing is greatly shortened, and the phenomena of sliding deflection and sliding when the turnover machine is turned over due to the fact that the side push plate is not in place seriously. The tobacco bale is time-consuming and labor-consuming to handle the skew cigarette packet that shifts, and linear bearing and guide arm are frequently changed simultaneously, and the accessory expense is higher, and the maintenance difficulty of the position stenosis.

Therefore, need design a novel side push pedal guiding mechanism, eliminate because of the asynchronous guiding mechanism jamming and the damage problem that leads to of cylinder, effectively guarantee the stability of side push pedal function, reduce because of the upset machine trouble that the side push pedal leads to not in place, guarantee the continuity of production and product quality's stability, reduce the expense and the maintenance work volume that guiding mechanism spare part was changed simultaneously.

Disclosure of Invention

1. adopt the guiding mechanism that combination bearing and guide rail formed, when the push pedal is flexible, eliminate because of the asynchronous guiding mechanism jamming and the damage problem that leads to of cylinder, effectively guarantee the stability of side push plate function, reduce because of the upset machine trouble that the side push plate does not put in place and lead to, guarantee the continuity of production and product quality's stability, reduce the expense and the maintenance work volume that guiding mechanism spare part was changed simultaneously.

2. Two combined bearings are used as guide wheels, when the side push plate extends out of and clamps the cigarette packet, the gravity of the gravity center forward-moving side push plate is large, the combined bearing of the guide mechanism needs to bear large reaction force at the moment, and the guide rail is high in strength and not prone to abrasion.

3. When the telescopic displacement difference of the left cylinder and the right cylinder of the push plate is large, the combined bearing can be subjected to a large extrusion force towards the left side or the right side, and the needle roller bearing on the end face of the combined bearing plays a guiding role, so that the clamping stagnation phenomenon cannot occur during telescopic movement.

4. When the combined bearing is contacted with the bearing supporting bottom plate, a certain gap exists between the combined bearing and the guide rail, so that the gap tolerance value between the combined bearing and the guide rail is increased, and the problem of bearing clamping stagnation caused by the asynchronism of the air cylinders is effectively solved.

5. The invention has simple structure, convenient manufacture and use, convenient disassembly and installation and is suitable for popularization and application.
