Description

Technical Field

[0001] This utility model relates to the technical field of cigarette packaging machine equipment, and in particular to a cigarette pack pushing device. Background Technology

[0002] In the cigarette packaging process, the pack pushing device is used to push the cigarette packs into the carton folding station for packaging. Existing pack pushing devices typically involve two movements: one is the continuous pushing of cigarette packs horizontally, and the other is the pushing of multiple cigarette packs as a group vertically for packaging. Existing pack pushing devices suffer from instability during pack ejection, resulting in unevenly ejected packs. Furthermore, existing pack pushing devices are inconvenient to adjust when changing cigarette pack sizes. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide a cigarette pack pushing device to solve the problem that the cigarette pack pushing device in the prior art is unstable in the pushing process and the pushed cigarette packs are not neatly pushed out.

[0004] This utility model solves the above-mentioned technical problems through the following technical means: a cigarette pack pushing device, which is set on the transverse conveying channel of cigarette packs, includes a pushing mechanism for pushing multiple cigarette packs vertically in the transverse conveying direction. The pushing mechanism includes a transverse push plate, a longitudinal baffle, a limiting plate, and a driving rod for pushing the transverse push plate to move reciprocally in the longitudinal direction. The limiting plate is set at the end point of the transverse conveying direction. A guide sleeve that slides with the driving rod is sleeved on the surface of the driving rod. The guide sleeve is fixedly set on the limiting plate. The transverse push plate and the longitudinal baffle are perpendicular to each other, and the longitudinal baffle, the limiting plate, and the driving rod are parallel. The length of the longitudinal baffle is greater than the maximum distance of the longitudinal movement of the transverse push plate.

[0005] Optionally, one end of the push plate is provided with a protrusion, and the limiting plate is provided with a sliding groove that matches the movement trajectory of the protrusion. The protrusion and the sliding groove are slidably engaged. The sliding groove restricts the displacement of the push plate in all directions through the protrusion. At the same time, the sliding groove also serves to limit the travel of the push plate in reciprocating longitudinal movement.

[0006] Optionally, the side of the horizontal push plate that contacts the cigarette pack is provided with horizontally arranged movable small push plates, the number of which is equal to the number of cigarette packs pushed out simultaneously in each longitudinal pushing action. Each movable small push plate is slidably connected to the horizontal push plate along the horizontal conveying direction through a horizontal guide rail structure, and each movable small push plate corresponds to the pushing position of one cigarette pack. Using independent movable small push plates to form a segmented push plate, so that each movable small push plate corresponds to the position of one cigarette pack, ensures that each cigarette pack is subjected to uniform force and reduces the possibility of cigarette pack tilting.

[0007] Optionally, the horizontal push plate is provided with a longitudinal groove, and the helical tooth plate forms a sliding pair with the longitudinal groove through a slider mechanism; the helical tooth plate is provided with a plurality of equally spaced helical teeth, each helical tooth being embedded in a mating groove on the back of an adjacent movable push plate, and the helical tooth plate is used to drive adjacent movable push plates to slide towards or away from each other, thereby adjusting the distance between the movable push plates. The helical tooth plate has a simple structure and can ensure the synchronicity of the adjustment of the distance between the movable push plates.

[0008] Optionally, guide plates are provided on both sides of the transverse conveying channel of the cigarette pack near the longitudinal baffle.

[0009] Optionally, the guide plates on both sides are provided with a guide bevel on the side of the tobacco pack conveying inlet.

[0010] Optionally, a fixed seat that can move along the transverse conveying direction is provided above the guide plate, and the guide plate and the fixed seat are slidably connected in the longitudinal direction to accommodate changes in the size and thickness of the cigarette pack.

[0011] The beneficial effects of this utility model are:

[0012] This invention utilizes a drive mechanism consisting of a horizontal push plate, a vertical baffle, a limiting plate, and a drive rod for reciprocating longitudinal movement of the horizontal push plate. This mechanism enables the vertical ejection of multiple cigarette packs along the transverse conveying direction. By incorporating a guide bushing to reduce wobbling during the reciprocating longitudinal movement of the drive rod, and by using a groove on the limiting plate with protrusions to restrict the horizontal push plate's directional offset, the ejection process is stable and the cigarette packs are ejected neatly. Furthermore, the use of a serrated plate allows for the synchronous outward expansion of all movable small push plates. Simultaneously, the guide plate can move along the transverse conveying direction and slide longitudinally, enabling this invention to adapt to variations in cigarette pack size and thickness, thus expanding its applicability.

[0018] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can understand the advantages and effects of this utility model from the content disclosed in this specification. It should be noted that the illustrations provided in the following embodiments are for illustrative purposes only and represent schematic diagrams, not actual pictures.

It is understandable that some well-known structures and their descriptions may be omitted in the figures for those skilled in the art.

In the description of this utility model, it should be understood that if terms such as "upper", "lower", "left", "right", "front", "rear", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the figure, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the terms used to describe the positional relationship in the figure are only for illustrative purposes and should not be construed as limiting this utility model. For those skilled in the art, the specific meaning of the above-mentioned terms can be understood according to the specific circumstances.

[0020] like Figures 1-4 As shown, this utility model discloses a cigarette pack pushing device, which is installed on the transverse cigarette pack conveying channel. It includes a pushing mechanism for pushing multiple cigarette packs (typically 10 packs at a time) vertically along the transverse conveying direction. The pushing mechanism includes a transverse push plate 11, a longitudinal baffle 2, a limiting plate 31, and a drive rod 4 for pushing the transverse push plate 11 to reciprocate longitudinally. The limiting plate 31 is fixedly installed at the end point of the transverse conveying direction to restrict the transverse movement of the cigarette packs. A sliding contact is provided on the surface of the drive rod 4. The guide sleeve 5 is fixedly mounted on the limiting plate 31. The guide sleeve 5 reduces the shaking when the drive rod 4 moves longitudinally back and forth. The horizontal push plate 11 is perpendicular to the vertical baffle 2, and the vertical baffle 2, the limiting plate 31 and the drive rod 4 are parallel. The length of the vertical baffle 2 is greater than the maximum distance of the longitudinal movement of the horizontal push plate 11. When the horizontal push plate 11 is fully pushed out longitudinally, the vertical baffle 2 still blocks the subsequent cigarette pack. When the horizontal push plate 11 retracts with the drive rod 4, the end of the vertical baffle 2 will not touch the cigarette pack.

[0021] In this embodiment, to further ensure the stability of the movement of the horizontal push plate 11, a protrusion 12 is provided at one end of the horizontal push plate 11. A groove 32 matching the protrusion 12 is provided on the limiting plate 31 corresponding to the movement trajectory of the protrusion 12. The protrusion 12 and the groove 32 are slidably engaged. The groove 32 restricts the displacement of the horizontal push plate 11 in all directions through the protrusion 12. At the same time, the groove 32 also serves to limit the travel of the reciprocating longitudinal movement of the horizontal push plate 11.

[0022] In this embodiment, the side of the horizontal push plate 11 that contacts the cigarette pack is provided with horizontally arranged movable small push plates 13, the number of which is equal to the number of cigarette packs pushed out at the same time in each longitudinal pushing action. Each movable small push plate 13 is slidably connected to the horizontal push plate 11 along the horizontal conveying direction through a horizontal guide rail structure, and each movable small push plate corresponds to the pushing position of a cigarette pack.

[0023] In this embodiment, the horizontal push plate 11 is provided with a longitudinal slide groove, and the oblique tooth plate 14 forms a sliding pair with the longitudinal slide groove through a slider mechanism; the oblique tooth plate 14 is provided with a number of equally spaced oblique teeth, and the inclination direction of the oblique teeth forms an acute angle with the transverse conveying direction. Each oblique tooth is embedded in the mating groove on the back of the adjacent movable push plate 13. The oblique tooth plate 14 is used to drive the adjacent movable push plates 13 to slide towards or away from each other, thereby adjusting the distance between the movable push plates and realizing the synchronous distance adjustment of all movable push plates 13 to adapt to cigarette packs of different thicknesses. The oblique tooth plate 14 that has slid into place can be fixed by fastening bolts and shims.

[0024] In this embodiment, guide plates 61 are provided on both sides of the transverse conveying channel for cigarette packs near the longitudinal baffle 2. The guide plates 61 on both sides have guide bevels 62 on one side of the cigarette pack conveying inlet. A fixed seat 63 is provided above the guide plate 61, which can move along the transverse conveying direction. The guide plate 61 and the fixed seat 63 are slidably connected in the longitudinal direction. This allows the guide plate 61 to move along the transverse conveying direction and slide along the longitudinal direction to accommodate and guide cigarette packs of different sizes.

[0025] It should be understood that this embodiment does not mention the speed adjustment of the transverse conveying channel, the proximity switch for transverse movement into position, the cylinder power source or other power source structure of the drive rod 4, the limit switch for the reciprocating longitudinal movement of the drive rod 4, and the corresponding control system, etc., which are in the prior art. Those skilled in the art can make their own settings and adjustments as needed without any inventive creativity.

[0026] It should be understood that in this embodiment, the direction of the cigarette pack conveying channel is set to horizontal, while the direction perpendicular to the cigarette pack conveying channel is vertical.

[0027] The working principle of this utility model is as follows:

[0028] In use, the cigarette pack pushing device of this utility model moves the rows of cigarette packs along the transverse conveying direction, passing through the guide plates 61 on both sides of the conveying channel. The guide slope 62 of the guide plate 61 is a gradually tightening inverted conical inlet shape, guiding the cigarette packs into the space between the guide plates 61 and arranging them neatly. When they reach the limit plate 31, the transverse conveying channel stops, and the drive rod 4 pushes the cigarette packs vertically. After the transverse push plate 11 reaches the maximum longitudinal movement distance, the longitudinal baffle 2 still blocks the cigarette packs inside the guide plate 61. With this setting, when the transverse push plate 11 retracts with the drive rod 4, the end of the longitudinal baffle 2 will not touch the cigarette pack. This cycle can continuously push a certain number of cigarette packs vertically to the subsequent process.

[0029] During this process, the swaying of the drive rod 4 during reciprocating longitudinal movement is reduced by setting the guide sleeve 5, and the slide groove 32 on the limit plate 31 restricts the offset of the horizontal push plate 11 in all directions through the protrusion 12, so that the pushing process is stable when the cigarette pack is pushed out and the pushed cigarette pack is neat.

[0030] Furthermore, when the inclined toothed plate 14 slides downward, the inclined teeth simultaneously engage between adjacent movable push plates 13, forcing the movable push plates 13 to slide along the transverse conveying direction. This achieves synchronous outward expansion of all movable push plates 13 to accommodate cigarette packs of different thicknesses. Simultaneously, the guide plate 61, in conjunction with the fixed base 63, can move both along the transverse conveying direction and slide along the longitudinal direction to accommodate and guide cigarette packs of different sizes. This allows the pusher device in this embodiment to adapt to changes in the size and thickness of the cigarette packs, thus improving the device's applicability.

[0031] The above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model. Technologies, shapes, and structural parts not described in detail in this utility model are all known technologies.
