However, with the progress of production technology, the method relying on thermal shrinkage is not suitable for production, and firstly, the thermal shrinkage method is easy to cause potential safety hazards; secondly, the energy consumption of this approach is high; thirdly, the thermal shrinkage film is poor in environmental protection performance and not beneficial to environmental protection requirements.

The inventor of the utility model has made a lot of research and development on the film covering, sealing and packaging, and the utility model is disclosed in Chinese patent application No.: CN202110558346.3 discloses a packaging process for a cigarette carton without cracking its envelope, but in actual production tests, the production process has a defect of poor stability, but the reason is that the packaging of cigarette carton piles belongs to a high-speed packaging process, and the control of the cigarette carton envelope is easy to have defects in the high-speed packaging process.

Therefore, the inventor readjusts the idea of the scheme, adopts a mode of combining incomplete film covering sealing with surrounding envelope, and only realizes the circumferential packaging of one cigarette carton pile by using the film covering sealing, so that the problems of untight coating and poor stability are avoided, and the other circumferential winding is realized by using the surrounding envelope, so that the tightness is enhanced, and the stability is improved. However, in the process, the cigarette carton pile subjected to film covering for the first time needs to pass through the surrounding film covering mechanism, the process needs to be wound in the circumferential direction, the bottom support cannot be realized, a relatively effective pushing structure is needed to realize stable transition of the cigarette carton pile, and therefore the scheme is formed.

SUMMERY OF THE UTILITY MODEL

Therefore, aiming at the problems, the utility model provides a cigarette carton pile pushing device which solves the technical problems of low efficiency and poor stability of the existing cigarette carton pile in the film coating process.

In order to achieve the purpose, the utility model adopts the following technical scheme: the strip cigarette stack pushing device comprises a support, an input conveying belt and a supporting bedplate, wherein the input conveying belt and the supporting bedplate are arranged on the support according to a production line, a push plate used for pushing a strip cigarette stack is arranged above the input conveying belt on the support, a pushing driving mechanism used for realizing the reciprocating motion of the push plate from the input conveying belt to the supporting bedplate is arranged on the support, and an avoiding mechanism used for realizing the avoidance of the strip cigarette stack by the push plate in a return motion is further arranged on the pushing driving mechanism.

Furthermore, a horizontal extension plate is arranged on the support and positioned on the support platen, a stretching driving mechanism for driving the horizontal extension plate to stretch out is arranged on the support, and the extension direction of the horizontal extension plate faces one side of the conveying direction.

Further, the horizontal extension plate is formed by a plurality of extension plates in parallel, each extension plate is connected with one extension driving mechanism, or each extension plate and the extension driving mechanism can be connected or disconnected.

Furthermore, a pressing auxiliary device for pressing or rolling the cigarette carton stack is arranged on the support above the supporting bedplate and on one side far away from the input conveyer belt.

Furthermore, the auxiliary pressing device comprises a pressing roller lifting mechanism arranged on the support and a roller rotatably arranged at the lower end of the pressing roller lifting mechanism.

Furthermore, the compression roller lifting mechanism is composed of a plurality of compression roller cylinders arranged side by side, and rollers are respectively and rotatably arranged at the free ends of the piston rods of the compression roller cylinders.

Furthermore, the avoiding mechanism is a push plate lifting mechanism and/or a push plate bending mechanism.

Furthermore, push pedal bending mechanism is including locating first connecting seat on the propelling movement actuating mechanism, locating the second connecting seat on the push pedal, locating the pushing mechanism that buckles on first connecting seat, first connecting seat passes through pivot rotatable coupling with the second connecting seat, and when the pushing mechanism that buckles moved, the change of vertical state to the horizontality was realized around the pivot to the push pedal.

A cigarette carton packing machine based on the same invention concept comprises a rack, a film covering mechanism, a cigarette carton stack pushing mechanism, a surrounding film covering mechanism and an output conveying belt, wherein the film covering mechanism, the film cigarette carton stack pushing mechanism, the surrounding film covering mechanism and the output conveying belt are arranged according to a production line, the distance between the output conveying belt and the cigarette carton pushing mechanism is larger than the film covering width of the surrounding film covering mechanism, the film covering mechanism is used for covering one circumference of a cigarette carton stack to form a first film covering, the surrounding film covering mechanism is used for covering the other circumference of the cigarette carton stack to form a second film covering, and the first film covering and the second film covering are respectively distributed along the transverse direction and the longitudinal direction of the cigarette carton stack.

Furthermore, a clamping and conveying mechanism used for being matched with the output conveying belt to realize clamping and conveying is arranged above the output conveying belt on the rack, and the clamping and conveying mechanism comprises a clamping and lifting mechanism arranged on the rack and a clamping and conveying belt arranged on the clamping and lifting mechanism.

By adopting the technical scheme, the utility model has the beneficial effects that:

1. this scheme has realized that the strip cigarette piles the automatic propelling movement process when going into around diolame mechanism after carrying out the cover membrane, because encircle the particularity of diolame mechanism, when it realizes encircleing the diolame, the week side of being wrapped by the thing is not allowed to have other objects, otherwise will be wrapped together, and the mode that utilizes the conveyer belt to carry is no longer suitable naturally. And because the surrounding envelope can also generate a circumferential shearing force on the packaged object, if a stable structure cannot be provided, errors in the packaging process can be easily caused.

In addition, the packaged article is a cigarette stack and is a set formed by stacking a plurality of cigarettes, and the circumference of the packaged article in the conveying direction is coated once, so that the whole cigarette stack is stable, but sealing and stabilizing are not realized. When the push plate is used for pushing, the side face of one side of the cigarette carton pile can be better covered, and a good pushing effect can be achieved. This causes a problem in that the area of the push plate is greatly increased, that is, the space occupied by its reciprocating stroke is increased, its weight is increased, and its cost is increased. At this time, of course, more than two push plates can be used to realize the dislocation action in a cyclic alternating manner, that is, the double stations are often said, but the occupied space is increased again, the weight is increased again, and the cost is increased again.

Therefore, the inventor realizes the purpose of effective avoidance by the design of the avoidance mechanism when the push plate reciprocates. The avoiding mechanism only needs to avoid the next entering cigarette stack when resetting after the cigarette stack is pushed once. The avoidance mechanism in the scheme can have a plurality of forms, such as lifting, left-right transverse moving, folding and the like.

Such as: the push plate lifting cylinder can be adopted to realize the lifting of the push plate, so that the stacking of the cigarette carton is avoided; the avoidance of the push plate can be realized by adopting the descending of the push plate lifting cylinder; if the push plate can be folded, the push plate is changed from vertical to horizontal, and the push plate can be avoided.

2. Because the film that encircles the diolame mechanism and adopt has certain width, when the width is less, the strip cigarette heap should encircle the diolame mechanism through, can utilize supporting platform and subsequent output conveyer belt just can realize the bearing without supporting. However, when the width of the film is wide, the stability of the cigarette carton stack as it passes through the wrapping mechanism is insufficient, and the wrapping process is not sufficiently maintained, and a certain amount of support is required.

By utilizing the horizontal extension plate, the cigarette carton can be extended out when the cigarette carton pile is pushed out, so that effective support is realized. The horizontally extending plate can be retracted when the other end of the stack of cigarettes has been supported by the output conveyor. The horizontally extending plate, although wrapped at one end within the membrane, is retractable toward the support deck.

3. If the width of the horizontally extending plate does not change when the width of the cigarette carton changes, the support is not favorable. That is, when the width of the horizontally extending plate is too small, the effect of supporting is poor, and when the width of the horizontally extending plate is large, a major force of the membrane is applied to the side of the horizontally extending plate, so that the membrane may be damaged when the horizontally extending plate is retracted. Thus, this problem is solved by forming the horizontally extending plates side by side with a plurality of extending plates that can be driven by a plurality of extension drive mechanisms or detachably connected to one extension drive mechanism.

4. The setting of pressing material auxiliary device, firstly in order to realize piling the leveling of the surperficial membrane of strip cigarette, secondly carry out the support of top to the strip cigarette heap to realize that the strip cigarette heap is when stretching out the support platen, its one end that stretches out does not have too big flagging. If the horizontal extension plate is provided, the acting force on the horizontal extension plate is also reduced, thereby realizing the increase of the service life. The pressing auxiliary device is not required to be too high in structure, and can be used for realizing smooth passing of the cigarette carton pile and pressing of the cigarette carton pile. In this scheme, set up a compression roller elevating system and roller, can make things convenient for the passing through of strip cigarette heap through the roller, through compression roller elevating system, can effectively realize effectively pressing when strip cigarette piles altitude variation.

5. When the width of the cigarette carton pile changes, the rolling change of the corresponding width can be realized by adjusting the actions of the plurality of compression roller cylinders, such as increasing or reducing the number of the actions of the compression roller cylinders.

6. The avoidance mechanism is a push plate lifting mechanism and/or a push plate bending mechanism, the push plate lifting mechanism and the push plate bending mechanism can be respectively arranged or can be simultaneously arranged, and the purpose of avoidance can be achieved. Of course, the push plate can also be a transverse moving mechanism, namely, the movement in the width direction is realized. The push plate lifting mechanism and the push plate transverse moving mechanism can be realized by adopting simple cylinders, and the push plate bending mechanism can also be realized by adopting a simple rotating mechanism. In this scheme, the push pedal bending mechanism adopts the mode of buckling to realize.

7. A cigarette carton packing machine realizes a reasonable work flow through the cooperation of a cigarette carton stacking and pushing mechanism, comprises a film covering mechanism, a cigarette carton stacking and pushing mechanism, a surrounding film covering mechanism and an output conveying belt, can realize quick and efficient packing, can realize the packing of 12-20 cigarette carton stacks per minute through tests, has better stability, and has better commercial application value compared with the packing of the existing cigarette carton stacks.
