[0025] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] The utility model provides a strip box pushing device, such as Figure 1 As shown, it includes a push module 1 for pushing the strip box and a drive module 2 for driving the push module 1; the push module 1 is connected to the drive module 2 through a connecting portion 3, the connecting portion 3 is detachably connected to the drive module 2 and there is a connecting force between them; the push module 1 includes a push portion 11, the strip box abuts against the push portion 11, and applies a reaction force to the push portion 11, when the reaction force is greater than the connecting force, the connecting portion 3 is separated from the drive module 2. When in use, once a cigarette jam occurs on the conveyor line, the reaction force applied by the strip box to the push portion 11 will be greater than the connecting force of the detachable connection, and the connecting portion 3 and the drive module 2 will separate by themselves, protecting the various components of the strip box pushing device from chain damage caused by overload, and extending the service life of the equipment. As a further improvement of this embodiment, the connecting portion 3 is magnetically connected to the drive module 2. In a specific embodiment, a magnetic attraction portion 7 is provided on the drive module 2, the connecting portion 3 is made of 45# steel, and the drive module 2 is adsorbed on the connecting portion 3 through the magnetic attraction portion 7. The magnetic connection can ensure a stable connection between the connecting portion 3 and the driving module 2 under normal working conditions, and allow the connecting portion 3 to be quickly separated from the driving module 2 when overloaded.

[0027] In some embodiments, the pushing module 1 and the driving module 2 are also movably connected via a movable part 4, so as to ensure that after the connecting part 3 is separated from the driving module 2, the relative position of the driving module 2 and the pushing module 1 can be ensured, thereby preventing the driving module 2 from falling and damaging components, and effectively protecting the safety of the equipment.

[0028] In some embodiments, the push module 1 further includes a guide structure, which includes a guide groove 12 and a slider 13 disposed in the guide groove 12. The slider 13 performs linear reciprocating motion in the guide groove 12 and is connected to the push unit 11. When in use, the slider 13 performs linear reciprocating motion in the guide groove 12, driving the push unit 11 to continuously push the bar box at intervals, which helps to improve the accuracy and consistency of the bar box pushing. As a further improvement of the above embodiment, a lubricating layer is provided in the guide groove 12, which can reduce the friction resistance of the slider 13 when it moves in the guide groove 12, so that the push unit 11 can move more smoothly when pushing the bar box, and reduce the wear rate of the slider 13, thereby extending the service life of related parts. The lubricating layer can be a smooth polishing treatment of the guide groove 12, or a lubricant can be coated on the surface of the guide groove 12.

[0029] In some embodiments, the driving module 2 includes a trigger 24 and a rocker 21, the trigger 24 and the rocker 21 are connected in a clutch manner, and the rocker 21 and the connecting portion 3 are detachably connected; when the trigger 24 contacts the rocker 21, the slider 13 moves along the guide groove 12 to drive the pushing portion 11 to push the box. When in use, the trigger 24 contacts the rocker 21 to trigger the rocker 21 to swing, driving the slider 13 along the guide groove 12 from left to right (in degrees). Figure 1 The trigger member 24 is separated from the rocker 21, driving the slider 13 along the guide groove 12 from right to left (in the direction shown in the figure). Figure 1 The pusher 11 moves in the direction shown in the figure as an example, and returns to the initial position to wait for the next push of the cartridge, further ensuring the accuracy and consistency of the cartridge push. When a cigarette is stuck, the slider 13 is stuck on the left side of the guide groove 12 (in the figure). Figure 1 The direction shown in the figure is taken as an example), and a reaction force is applied to the connecting part 3. The reaction force is greater than the connecting force between the connecting part 3 and the rocker 21. The connecting part 3 and the rocker 21 separate themselves, thereby protecting the components of the box push device from damage.

[0030] In some embodiments, the connecting portion 3 includes a first connecting rod 31 and a second connecting rod 32 that are movably connected to each other, the first connecting rod 31 is connected to the slider 13, and the second connecting rod 32 is connected to the rocker 21. The movable connection between the first connecting rod 31 and the second connecting rod 32 allows the two connecting rods to rotate relative to each other within a certain range to adapt to the relative position change between the slider 13 and the rocker 21.

[0031] In some embodiments, in order to achieve precise control of the pushing action, the driving module 2 includes a cam 23, and the raised portion of the cam 23 forms a trigger 24. As a further improvement of this embodiment, a roller 22 is provided on the rocker 21, and the roller 22 is clutch-connected with the trigger 24. Compared with sliding friction, the rolling friction between the roller 22 and the cam 23 significantly reduces the friction resistance between the contact surfaces, reduces energy loss, and improves the transmission efficiency of the device.

[0032] In some embodiments, a rotating portion 5 is provided at the end of the rocker 21, and the rocker 21 performs a reciprocating rotational motion around the rotating portion 5 at a certain angle; the rocker 21 is installed through the elastic portion 6, and when the trigger member 24 contacts the rocker 21, the trigger member 24 applies a thrust to the rocker 21 to drive the rocker 21 to rotate around the rotating portion 5 in a clockwise direction (in degrees). Figure 1 The elastic part 6 applies a rebound force to the rocker 21 to drive the rocker 21 to rotate around the rotating part 5 in a counterclockwise direction (in the direction shown in FIG. Figure 1 When in use, when the trigger member 24 pushes the rocker 21 to rotate in the clockwise direction, the elastic part 6 is stretched to store energy; when the trigger member 24 is separated from the rocker 21, the elastic part 6 releases the stored energy and drives the rocker 21 to rotate in the counterclockwise direction. This process realizes energy recycling and helps to reduce the energy consumption of the device. In addition, the rebound force provided by the elastic part 6 can play a buffering role in the pushing process, reduce the impact of the rotation of the rocker 21 on the device itself, and extend the service life of the device.
