Paper buckling assembly for cigarette manufacturing machine

Abstract

A paper buckling assembly for a cigarette manufacturing machine comprises a buckling frame having a first end and a second end. The buckling frame is configured to be coupled to a support frame of a cigarette manufacturing machine, such that the first end of the buckling frame aligns with a filling pipe of the cigarette manufacturing machine. The buckling frame carries a rear buckling element and a front buckling element. The rear buckling element is distal to the first end of the buckling frame, and the front buckling element is proximal to the first end of the buckling frame. The rear buckling element and the front buckling element are slidably disposed within the buckling frame and are connected through an elastic member. The rear buckling element includes a catch member for engagement with an actuating assembly of the cigarette manufacturing machine.

         4 . The paper buckling assembly according to  claim 1 , wherein a gripping element is disposed on the front buckling element. 
     
     
         5 . The paper buckling assembly according to  claim 4 , wherein the gripping element is provided with a curved surface, and the curved surface is configured to fit with the outside surface of the cigarette tube. 
     
     
         6 . A machine for manufacturing a cigarette, the machine comprising:
 a housing;   a support frame disposed within the housing, the support frame comprising a tobacco cavity aligned with an opening in the housing for receiving tobacco into the tobacco cavity;   a filling pipe at least partially disposed outside of the housing, wherein the filling pipe is in communication with the tobacco cavity and configured to support an empty cigarette tube;   a paper buckling assembly comprising:
 a buckling frame coupled to the support frame, such that a first end of the buckling frame aligns with the filling pipe; 
 a rear buckling element carried by the buckling frame, distal to the first end of the buckling frame; and 
 a front buckling element carried by the buckling frame, proximal to the first end of the buckling frame; 
 wherein the rear buckling element and the front buckling element are slidably disposed within the buckling frame and are connected through an elastic member, and 
   an actuation assembly assembled with the housing and operatively connected to the rear buckling element, wherein actuation of the actuation assembly causes the rear buckling element to slide toward the front buckling element, such that the elastic member supplies a buckling force to the front buckling element for movement of the front buckling element against a cigarette tube installed on the filling pipe.   
     
     
         7 . The machine according to  claim 6 , further comprising a push plate at least partially disposed within the support frame, wherein the actuation assembly is operatively connected to the push plate, such that actuation of the actuation assembly causes the push plate to move from a first position to a second position to push tobacco in the tobacco cavity into alignment with the filling pipe. 
     
     
         8 . The machine according to  claim 6 , wherein the actuation assembly comprises a handle connected with a rotation rod for rotating actuation of the rotation rod, and a connector disposed on the rotation rod for engagement with a catch member of the rear buckling element. 
     
     
         9 . The machine according to  claim 8 , wherein a protrusion is disposed on the connector, wherein the catch member is configured as a rectangular frame disposed on an end of the rear buckling element away from the front buckling element, and wherein the catch member is sleeved on the protrusion such that the protrusion contacts the inner wall of the catch member. 
     
     
         10 . The machine according to  claim 9 , wherein the protrusion is configured to follow an arc-shaped path during operation of the actuation assembly. 
     
     
         11 . The machine according to  claim 6 , wherein a positioning assembly is disposed between the front buckling element and the rear buckling element and is configured to limit the elastic member. 
     
     
         12 . The machine according to  claim 11 , wherein the elastic member comprises a spring and the positioning assembly comprises a rear spring seat and a front spring seat, and wherein the rear spring seat is disposed on the rear buckling element, the front spring seat is disposed on the front buckling element, and two ends of the spring are respectively sleeved on the rear spring seat and the front spring seat. 
     
     
         13 . The machine according to  claim 6 , wherein a gripping element is disposed on the front buckling element. 
     
     
         14 . The machine according to  claim 13 , wherein the gripping element is provided with a curved surface, and the curved surface is configured to fit with the outside surface of the cigarette tube.
