Description

Technical Field

[0001] The utility model relates to the technical field of cigarette packet conveying, in particular to a cigarette packet conveying reversing device. Background Art

[0002] In the tobacco field, a packaging unit is used to complete the packaging and forming process of slim cigarettes. The packaging machine consists of various packaging machines (such as small box packaging machines, small box transparent paper packaging machines, strip box packaging machines, etc.) and a conveying device.

[0003] At present, during the packaging process of a certain brand of cigarettes, unlike most traditional cigarette packaging, the strips need to be packaged in upright packs (the traditional packaging of cigarette packs in strip boxes is in the form of "25 flat packs", with two packs of cigarette packs stacked in each pack, and a total of five groups of horizontal stacks are conveyed. However, some existing cigarette packs in strip boxes are packaged vertically), that is, the cigarette packs need to be conveyed vertically, and ten packs of flat cigarette packs need to be turned to an upright state.

[0004] The existing cigarette pack conveying reversing device consists of a reciprocating cigarette pushing mechanism, a discharge conveyor belt, a feed conveyor belt, a rotating dial wheel and a negative pressure adsorption mechanism. The cigarette pack enters through the feed conveyor belt, and then turns through the cooperation of various components, and finally is discharged through the discharge conveyor belt, thereby realizing the transformation from lying flat to standing.

[0005] However, in actual use, it was found that its structure is complex and it adopts many mechanisms, which not only has high manufacturing costs, but also high subsequent maintenance costs. At the same time, the reciprocating smoke pushing mechanism, the discharge conveyor belt, the feed conveyor belt and the rotating dial wheel all need to occupy a certain workshop space for installation. Although the discharge conveyor belt and the rotating dial wheel can partially overlap, other mechanisms all need to occupy the workshop space independently for installation, which makes the overall workshop space occupied larger. For this reason, improvements are proposed. Utility Model Content

A rotating assembly is installed between the two support seats. Multiple groups of adsorption rollers are evenly fixedly installed on the outer surface of the rotating assembly, and the adsorption rollers match the through grooves.

[0010] Multiple groups of adsorption rollers are fixedly connected to a circular sleeve, and a plurality of connection holes are opened on one side of the outer surface of the circular sleeve, and the connection holes are connected to adjacent adsorption rollers;

[0011] An annular seat is sealed and rotatably sleeved on one side of the outer surface of the circular sleeve. An arc cavity is opened inside the annular seat, and the arc cavity is communicated with the adjacent connecting hole. A vacuum assembly is installed between the arc cavity and the roller conveyor.

[0012] Furthermore, the rotating assembly includes a motor, and the motor is fixedly mounted on one side of the outer surface of the adjacent support seat. The drive shaft of the motor passes through the support seat and is fixedly connected to a rotating drum, and the rotating drum is rotatably connected to the two support seats to facilitate driving multiple adsorption rollers to rotate.

[0013] Furthermore, multiple groups of adsorption rollers each include two support rods, and the support rods are fixedly connected to the rotating drum and the circular sleeve and are connected to adjacent connecting holes. An auxiliary rod is fixedly passed through one side of the outer surface of the two support rods. Multiple adsorption holes are opened on one side of the outer surface of the two auxiliary rods, and the adsorption holes are connected to the interior of the auxiliary rods. A local area inside the support rods is hollowed out to facilitate the connection between the connecting holes and the auxiliary rods.

[0014] Furthermore, the vacuum assembly includes a fixed tube, and the fixed tube is fixedly connected to the annular seat and communicates with the arc cavity. A vacuum pump is fixedly passed through the other end of the fixed tube, and the vacuum pump is fixedly installed on one side outer wall of the roller conveyor. The vacuum pump can vacuum the arc cavity through the fixed tube.

[0015] Furthermore, the annular seat is fixedly connected to the adjacent support seat, and the support seat supports the annular seat, which is beneficial to the installation of the annular seat.

[0016] Furthermore, the two through slots are both located between two adjacent rollers on the roller conveyor. When the support rod moves through the through slots, the rollers on the roller conveyor can avoid affecting it.

[0017] Furthermore, a fixing frame is fixedly connected between the outer walls of the two discharging conveyor belts, and the provision of the fixing frame is conducive to the installation of the two discharging conveyor belts.

[0018] Beneficial effects of the utility model:

[0019] When the utility model is in use, the cigarette pack conveying reversing device, through the roller conveyor, U-shaped limit frame, through groove, support seat, rotating assembly, adsorption roller, round sleeve, annular seat, connecting hole and vacuum assembly, utilizes the roller gap of the roller conveyor to partially overlap the steering mechanism with it, replacing the original feed conveyor belt and reciprocating cigarette pushing mechanism, reducing the mechanism setting, reducing the manufacturing cost and the subsequent maintenance cost, and at the same time the steering mechanism overlaps with the roller conveyor and the discharge conveyor belt, and eliminates the space occupied by the original reciprocating cigarette pushing mechanism, making the whole more compact and reducing the workshop space occupied.

[0031] Multiple groups of adsorption rollers are evenly fixedly installed on the outer surface of the rotating component, and the adsorption rollers are matched with the through groove 6. Multiple groups of adsorption rollers are commonly fixedly connected to the circular sleeve 7. Multiple connecting holes 16 are provided on one side of the outer surface of the circular sleeve 7, and the connecting holes 16 are connected to adjacent adsorption rollers.
