The transverse compression bar 8-2-2 is provided with a transverse shaft 8-2-5 with a roller, the roller is jointed with a wedge-shaped block 8-2-6 at the other end of the pre-pressing cover part 8-1 and the gland swing rod 8-1-2, and a support shaft of the gland swing rod 8-1-2 is provided with a volute spiral spring acting on the gland swing rod 8-1-2.

And a gland guide rod 8-3 in transmission connection is arranged at the other end of the linkage swing rod of the empty cigarette case conveying part of the cover opening mechanism, which is opposite to one end of the transmission connection box pushing guide rod. The gland guide rod 8-3 is provided with a guide sleeve and is vertical to the cigarette case stepping conveying belt 4. A box pushing rod 8-4 corresponding to the closed cover part 8-2 cigarette box jacket 8-2-4 is fixed on the mounting plate at the end of the gland guide rod 8-3.

It should be noted that the sliding sleeve is fixedly installed on the frame 1. In this embodiment, the jacket 8-2-4 is fixed to the sliding sleeve, and the jacket 8-2-4 includes a clamp groove and a clamp plate installed on an inner side surface of the clamp groove through a spring. The box pushing rod 8-4 is mechanically linked with the cover opening mechanism 7 and pushes the cigarette box which passes through the pre-pressing cover to move from the cigarette box stepping conveying belt 4 to the clamping sleeve 8-2-4. The descending action of the lifting rod 8-2-1 drives the vertical pressure head 8-2-3 to press the cigarette case cover, the cigarette case cover is completely closed in the pressing process, and the cigarette case finally falls from the jacket 8-2-4 to the conveying belt below the jacket. In this embodiment, a sliding sleeve supported guide rod is connected between the front end and the rear end of the cover guide rod 8-3 to enhance the stability of the push box guide rod 7-1-5.

Referring to fig. 14, a cigarette case vacancy detection sensor is disposed on a rack on one side of the cigarette case stepping conveyor belt on the rear side of the cover opening mechanism, and a cigarette rejecting mechanism 9 corresponding to the cigarette mold case is disposed on a rack on one side of the cigarette case stepping conveyor belt. The cigarette rejecting mechanism 9 is provided with a disk rejecting cam 9-1 connected with a power mechanism, the disk rejecting cam 9-1 is provided with a control groove and a swing groove, a support of the rack is provided with a transverse lock rod 9-2 connected with a sliding key of the rack, a lock plate 9-3 in sliding connection with the longitudinal slide way of the rack is arranged in the longitudinal slide way of the rack, a groove of the lock plate 9-3 is in locking connection with a bulge of the transverse lock rod 9-2, the upper part of the lock plate 9-3 is provided with an energy storage spring 9-4, the bottom of the lock plate 9-3 is provided with a control rod 9-5 which is up-down corresponding to the control groove of the disk rejecting cam 9-1, the lower part of the lock plate 9-3 is provided with a transverse push-pull rod 9-6 fixedly connected with the lock plate, a contact rod 9-7 which is up-down corresponding to the swing groove of the disk rejecting cam, the machine frame is provided with a swing arm 9-8 supported by a shaft, the end part of a transverse push-pull rod 9-6 is connected with the middle part of the swing arm 9-8 through a shaft, the end part of the swing arm 9-8 is provided with a connecting rod connected with the shaft, and the connecting rod is connected with a cigarette pushing rod 9-9 shaft supported on a sliding sleeve through a shaft. The machine frame is provided with a cigarette pushing cylinder, a piston rod of the cigarette pushing cylinder is connected with a transverse locking rod 9-2, a vacancy signal output by the cigarette case vacancy detection sensor is connected with a PLC (programmable logic controller), and a control output end of the cigarette case vacancy detection sensor is connected with a cigarette pushing cylinder push stroke control electromagnetic valve.

It should be noted that the cigarette pushing cylinder receives the cigarette case vacancy detection sensor to trigger the transverse lock rod 9-2 and the lock plate 9-3 to be separated instantly, and after the disc-shaped rejecting cam 9-1 drives the cigarette pushing rod to reciprocate once, the transverse lock rod 9-2 and the lock plate 9-3 are clamped, so that one-time cigarette rejection is realized.

A baffle plate for preventing the cigarette groups from spilling from the cigarette case is arranged between the cigarette upward pushing mechanism and the cigarette case cover closing mechanism close to the cigarette case stepping conveying belt.

The lining paper storage box of the lining paper laying mechanism and the elastic sheet, the paper taking lifting frame, the supporting rod and the sucking disc thereof are arranged in double stations and synchronously act; the U-shaped bracket, the flanging plate and the cigarette supporting plate of the cigarette upward pushing mechanism are arranged in double stations and synchronously act; the cigarette case stepping conveying belt and the cigarette case pushing cylinder are arranged at double stations and act synchronously; the length of a friction rolling shaft of the cover opening mechanism corresponds to two empty cigarette cases of the cigarette case stepping conveying belt; the right-angle swing rod, the ejector rod, the pre-pressing swing rod and the protrusion double-station of the pre-pressing cover part of the cigarette case cover closing mechanism are arranged and synchronously operated, and the lifting rod, the transverse pressing rod, the vertical pressing head and the jacket double-station of the closing cover part of the cigarette case cover closing mechanism are arranged and synchronously operated; the cigarette case blank detection sensor corresponding to two blank cigarette cases is arranged on the rack on one side of the cigarette case stepping conveying belt, and cigarette rejecting mechanisms corresponding to two cigarette mold cases are arranged on the rack on one side of the cigarette mold case stepping conveying belt.

The double-station arrangement refers to the arrangement symmetrically along the conveying direction of the cigarette stepping conveying belt or the cigarette case stepping conveying belt and synchronously acts on the cigarette groups or the empty cigarette cases of the two cigarette mold boxes. The structure can realize double-station synchronous action of cigarette filling, and the cigarette filling efficiency is doubled.
