In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0046] like Figures 1 to 6 As shown, on the one hand, this embodiment provides a pushing fixture, which includes a pin seat 10 and a pin shaft 20. The pin seat 10 is provided with two insertion holes 121. The two ends of the pin shaft 20 are respectively inserted into the two insertion holes 121 and are detachably connected to the pin seat 10. A penetration space is enclosed between the pin shaft 20 and the pin seat 10 for penetrating a conveyor belt 30. The pin shaft 20 is clamped between two adjacent teeth of the conveyor belt 30. The conveyor belt 30 can drive the pin seat 10 to move synchronously through the pin shaft 20 for pushing cigarette packs.

[0047] By setting a pin shaft 20 and a pin seat 10, the pin shaft 20 is clamped between two adjacent teeth of the conveyor belt 30, and the conveyor belt 30 is inserted into the insertion space between the pin shaft 20 and the pin seat 10, so that the push-fixer is fixed to the conveyor belt 30, so as to replace the fixing method of screws, reduce the stress concentration of the conveyor belt 30, thereby effectively improving the fatigue damage of the conveyor belt 30 and increasing the service life of the conveyor belt 30; when replacing the conveyor belt 30, the pin shaft 20 can be removed from the pin seat 10 to remove the push-fixer from the conveyor belt 30, which is more convenient and quicker than loosening the screws, and can save replacement time, thereby ensuring production efficiency.

[0048] Specifically, the pin seat 10 includes a base 11 and two supporting parts 12. The base 11 is used to protrude on the outside of the conveyor belt 30 to push the cigarette pack; the two supporting parts 12 are relatively arranged on the base 11 at a preset distance, and the insertion hole 121 is arranged on the supporting part 12; the preset distance between the two supporting parts 12 matches the width of the conveyor belt 30.

[0049] Optionally, the pin seat 10 and the pin shaft 20 are both made of metal; when removing the push-fixer from the conveyor belt 30, a tool is used to pry apart the two support portions 12, and the distance between the two support portions 12 is increased, so that the pin shaft 20 is removed. It can be understood that a single push-fixer can be removed for replacement; after all the push-fixers on the conveyor belt 30 are removed, the conveyor belt 30 can be replaced, and then the push-fixer can be installed on the conveyor belt 30.

[0050] In this embodiment, both of the two insertion holes 121 are through holes, and the axes of the two insertion holes 121 coincide; the shape of the insertion hole 121 matches the shape of the pin shaft 20, and the size of the insertion hole 121 is slightly smaller than the size of the pin shaft 20; the inner side of the conveyor belt 30 has teeth, and there are grooves between adjacent two teeth; the pin shaft 20 is cylindrical, the cross section of the groove is semi-circular, and the pin shaft 20 is clamped in the groove.

[0051] In this embodiment, the pin seat 10 is in a π shape; the base 11 and the two supporting parts 12 are of an integral structure. By arranging the base 11 on the outer side of the conveyor belt 30 and the pin shaft 20 on the inner side of the conveyor belt 30, the pushing fixture can be fixed on the conveyor belt 30 by using the tooth shape on the inner side of the conveyor belt 30, without setting screws, and the structure is compact and convenient for disassembly and assembly.

[0052] Optionally, the base 11 is in a flat plate shape, the supporting part 12 extends perpendicular to the plane where the base 11 is located, and the two supporting parts 12 respectively fit the conveyor belt 30 from both sides; the width of the supporting part 12 gradually increases towards the direction close to the base 11.

[0053] By arranging the base 11 in a flat plate shape and the supporting part 12 extending perpendicular to the plane where the base 11 is located, the base 11 fits on the outer side of the conveyor belt 30, and the two supporting parts 12 respectively fit on the left and right sides of the conveyor belt 30, which is beneficial to ensuring the stability of the pushing fixture. By arranging the width of the supporting part 12 to gradually increase towards the direction close to the base 11, the strength at the connection of the base 11 and the supporting part 12 is ensured, the pin seat 10 is made more durable, and the service life of the pin seat 10 is improved.

[0054] As Figures 6 to 9 shown, on the other hand, this embodiment provides a cigarette packet conveying device, which includes a driving component, a conveyor belt 30 and the above-mentioned pushing fixture. The pushing fixture is arranged on the conveyor belt 30, and the conveyor belt 30 moves under the action of the driving component and drives the pushing fixture to move synchronously.

[0055] By arranging the pushing fixture with the pin shaft 20 and the pin seat 10, the fatigue damage of the conveyor belt 30 is effectively improved. The pushing fixture is convenient to replace and disassemble, saves the replacement and maintenance time, and improves the production efficiency.

[0056] In the prior art, the pushing block is fixed on the conveyor belt by screws, and the conveyor belt is prone to fatigue damage such as stretching or breaking; when the conveyor belt is stretched, the cigarette packets cannot be pushed in place, resulting in wrinkles or damage caused by the collision of the cigarette packets, making the cigarette packet products unqualified; when irregular cigarette packets such as rotten or damaged packets pass through, it is very easy to cause the equipment to clamp cigarettes, resulting in equipment shutdown; when the clamping position occurs at the position of the pushing block, the conveyor belt is prone to stretching or breaking and is basically difficult to repair; replacing the conveyor belt during shutdown takes a long time, increasing the production cost and reducing the production efficiency.

[0057] By setting a pushing and fixing device with a pin shaft 20 and a pin seat 10, the stress concentration of the conveyor belt 30 is reduced, the service life of the conveyor belt 30 is increased, and the frequent damage and frequent replacement of the conveyor belt 30 are avoided; the damage of cigarette packets caused by the stretching of the conveyor belt 30 is improved, which helps to ensure the quality of cigarette packet products.

[0058] Specifically, the conveyor belt 30 is connected end to end, the inner side of the conveyor belt 30 has teeth, and the outer side surface of the conveyor belt 30 is smooth; the driving assembly includes belt pulleys 41 and a driving shaft 42. Two belt pulleys 41 are arranged at intervals. The conveyor belt 30 is arranged outside the two belt pulleys 41 and meshes with the belt pulleys 41; the driving shaft 42 is arranged corresponding to the belt pulley 41 one by one. The driving shaft 42 passes through the belt pulley 41 and can drive the belt pulley 41 to rotate. The cooperation of the two belt pulleys 41 and the two driving shafts 42 can realize the movement of the conveyor belt 30. The movement of the conveyor belt 30 drives the pushing and fixing device to move synchronously, so as to convey cigarette packets. In this embodiment, the two belt pulleys 41 are arranged at intervals in the vertical direction, and the conveyor belt 30 can move and drive the pushing and fixing device to rise or fall in the vertical direction.

[0059] In order to avoid the pushing and fixing device, the belt pulley 41 has a toothed area 413 and an avoidance area 414. The toothed area 413 meshes with the conveyor belt 30, and the avoidance area 414 is used to avoid the pushing and fixing device. By setting the avoidance area 414 on the belt pulley 41, when the conveyor belt 30 moves, the pin shaft 20 of the pushing and fixing device can be placed in the avoidance area 414, which can not only drive the conveyor belt 30 to move, but also set the pin shaft 20 inside the conveyor belt 30.

[0060] In this embodiment, there are two conveyor belts 30, which are the first conveyor belt 311 and the second conveyor belt 312 respectively. The first conveyor belt 311 and the second conveyor belt 312 are arranged oppositely and are both provided with pushing and fixing devices for clamping the cigarette packets from both sides and driving the cigarette packets to move synchronously; there are two driving assemblies, and the two driving assemblies are respectively used to drive the two conveyor belts 30 to move. By setting two opposite conveyor belts 30 and using the two conveyor belts 30 to clamp the cigarette packets from both sides, it helps to improve the stability of cigarette packet transportation.

[0061] In this embodiment, each driving assembly includes two belt pulleys 41 and two driving shafts 42. The two belt pulleys 41 are the first belt pulley 411 and the second belt pulley 412 respectively, and the two driving shafts 42 are the first driving shaft 421 and the second driving shaft 422 respectively; the first driving shaft 421 is inserted into the first belt pulley 411, and the second driving shaft 422 is inserted into the second belt pulley 412.

[0062] In this embodiment, a plurality of pushing fixators are arranged at intervals on each conveyor belt 30; two adjacent pushing fixators on one conveyor belt 30 and two adjacent pushing fixators on the other conveyor belt 30 can cooperate to convey a cigarette packet together.

[0063] It can be understood that one conveyor belt 30 can also be provided, and a pushing fixator is arranged on the conveyor belt 30. The cigarette packet is placed on the base 11 of the pushing fixator, and the base 11 supports the cigarette packet and drives the cigarette packet to move.

[0064] Obviously, the above embodiments of the present utility model are merely examples for clearly illustrating the present utility model, rather than limiting the implementation manners of the present utility model. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present utility model. It is not necessary and impossible to enumerate all the implementation manners here.
