[0002] With the popularization of fancy cigarettes, the consumer market of Jinzhongzhi is getting wider and wider, the demand is getting bigger and bigger, and the requirements for equipment are getting higher and higher. In the production of cigarette packaging, the problem of small boxes being stuck due to the failure of cigarette box blanking to be pushed into place will bring serious problems to the equipment in production and use. To this end, we analyzed the reasons for the failure of cigarette box blanking to be pushed into place, and summarized the factors that cause the failure of cigarette box blanking to be pushed into place: Figure 1 As shown, there is a cigarette box blanking pushing protection device under the No. 1 pressing plate of the YB417C hard box packaging machine. The main components include the existing mounting plate 01, the elastic steel plate 02 and the existing anti-retraction roller 03. The existing anti-retraction roller 03 is connected to the existing mounting plate 01 through the elastic steel plate 02. The function of the existing anti-retraction roller 03 is to stop the retreat. The cigarette pusher pushes the box into the crawler mold box. When the cigarette pusher retracts, it is easy to deviate the small box belt from the mold box. The existing anti-retraction roller 03 uses the elasticity of the elastic steel plate 02 to make the pushed small box overcome the force of the elastic steel plate 02 and enter the mold box channel. However, the elastic steel plate 02 is easy to break after a long time, causing the fragments of the elastic steel plate 02 to fall into the belt or the mold box, causing equipment damage, breaking the mold box, affecting production, and the elastic steel plate 02 is hard and used frequently, resulting in fatigue damage, and easy plastic deformation, resulting in poor anti-retraction effect, and the small box is not pushed into the mold box position, which is stuck. The above situation is the main factor causing the cigarette boxes to not be pushed into place. Failure to push the cigarette boxes into place will cause the small boxes to be stuck, resulting in equipment downtime, product quality problems, etc. Utility Model Content

[0059] The following is a description of the implementation of the present invention by means of specific embodiments. People familiar with the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification.
[0060] It should be noted that the structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the limiting conditions for the implementation of the utility model, so they have no substantial technical significance.

Each mold box 53 is in a groove shape and is used to load a cigarette box to be transported (not shown in the figure). Since the mounting structure 1 of the cigarette box blanking push protection device is arranged on the swing frame 6, the cigarette box blanking push protection device moves with the swing frame 6. When the hard box packaging machine is running, the swing frame 6 switches to the first state so that the cigarette box blanking push protection device is close to the blanking push mechanism 7 to avoid the cigarette box pushed into the mold box 53 from being returned. When the cigarette box blanking push protection device needs to be disassembled for maintenance, the swing frame 6 switches to the second state so that the cigarette box blanking push protection device is away from the blanking push mechanism 7.
[0067] Recombination Figure 3 and Figure 4 In view of the shortcomings of the prior art, the present application changes the elastic steel plate in the original design into a retractable pre-stressed elastic member 32. Specifically, the cigarette box falling material pushing protection device of the present utility model includes:
[0068] The mounting structure 1 comprises a mounting body 11 and a cantilevered portion 12 disposed on the top of the mounting body 11, and a mounting hole 13 is disposed on the cantilevered portion 12;
[0069] A suspension arm 2, wherein two ends of the suspension arm 2 are respectively a hinged end and a suspended end, and the hinged end of the suspension arm 2 is rotatably disposed on the mounting body 11;
[0070] The elastic limiting component 3 includes a suspension constraint 31 and a preload elastic component 32. The suspension constraint 31 is movably inserted into the mounting hole 13. The bottom end of the suspension constraint 31 is connected to the suspension arm 2. The top end of the suspension constraint 31 has a stopper head 311 that abuts against the cantilever part 12. The preload elastic component 32 is sleeved on the suspension constraint 31. The two ends of the preload elastic component 32 along the elastic force direction respectively apply pressure to the cantilever part 12 and the suspension arm 2.
[0071] The anti-retraction roller 4 is arranged horizontally, and includes a mounting shaft 41 and a roller body 42 rotatably sleeved on the mounting shaft 41. The mounting shaft 41 is connected to the suspended end of the suspension arm 2 to move with the suspension arm 2. The distance between the roller body 42 and a cigarette box pushing slideway of a blanking pushing mechanism is less than the thickness of the cigarette box.
[0072] When the cigarette box passes the lower side of the anti-retraction roller 4 along the cigarette box pushing slide, the cigarette box lifts the anti-retraction roller 4 to a preset height and the upper surface of the cigarette box rolls with the roller body 42;
[0073] When the cigarette box is pushed into place, the stop roller 4 drops to its original position.

When the cigarette box passes the lower side of the anti-retraction roller 4 along the cigarette box pushing slide, the cigarette box lifts the anti-retraction roller 4 to a preset height and the upper surface of the cigarette box rolls with the roller body 42. At this time, the stop head 311 no longer abuts against the cantilever 12, and the elastic potential energy of the preload elastic member 32 becomes larger. When the cigarette box is pushed into place, since there is no cigarette box at the lower side of the anti-recoil roller 4, the anti-recoil roller 4 falls to the original position; at this time, the stop head 311 abuts against the cantilevered part 12, and the elastic potential energy of the pre-stressed elastic member 32 becomes smaller. The pre-stressed elastic member 32 can be a compression spring.
