Technical Field

[0001] The utility model relates to the technical field of cigarette preparation, in particular to a feeding device of an empty cigarette tube cigarette maker. Background Art

[0002] In the preliminary experiments to study and evaluate the composition, smoke and taste of tobacco, the experimental cigarettes are usually prepared by filling empty tubes with modulated tobacco. The automation of the equipment is mainly focused on the automated supply process of tobacco, because the compaction of tobacco into rods is more difficult to solve through automation and the entire process is relatively long.

[0003] The empty cigarette tube itself is a product output by the production line. During the process of filling tobacco, the empty tube only needs to be placed in the preset position. In the past, the empty tube was mostly installed manually. Because the processing of tobacco is long and the processing rhythm of the empty tube is slow, manual participation does not affect the preparation efficiency.

[0004] With the improvement of automation requirements, there is a method of automation using rollers surrounding the empty tube slots, such as the application number CN202410267298.6, the invention name is: an invention patent for automatic filling equipment of multiple specifications of tobacco, etc. This method uses negative pressure to adsorb the empty tube, but the empty tube structure is empty inside, the adsorption force is difficult to control, and it is easy to cause damage to the empty tube. Therefore, it is necessary to develop a new empty tube feeding method to solve the problem of automatic feeding while ensuring that the empty tube is not easy to deform.

[0005] In order to solve the above problems, people have been seeking an ideal technical solution. Utility Model Content

[0011] When the empty cylinder loading top plate is in a high stroke state, the extension line of the guide surface can extend to the top of the circular arc groove.

DETAILED DESCRIPTION

[0026] The technical solution of the utility model is further described in detail below through specific implementation methods.

[0027] like Figure 1-Figure 4 As shown, a loading device for an empty cigarette tube maker comprises a hopper 1, an empty tube lifting mechanism 2 and an empty tube transferring mechanism 3.

[0028] The hopper 1 includes an inclined bottom wall 11 and side walls 12 on both sides. The front end of the hopper 1 is empty. The width of the bottom wall 11 of the hopper 1 is greater than the length of the empty cigarette tube 4. It is generally set in a slightly larger manner to leave a small gap between the empty cigarette tube 4 and the side walls 12 on both sides. On the one hand, it is convenient for the rolling of the empty cigarette tube 4, and on the other hand, it prevents the empty cigarette tube 4 accumulated in the hopper 1 from having excessive axial deviation. A crossbeam is provided on the top of the front end of the hopper 1, and the two ends of the crossbeam 13 are respectively fixed to the side walls 12 on both sides, so as to ensure the stability of the hopper 1 without hindering the loading work.

[0029] The empty barrel lifting mechanism 2 includes an empty barrel loading top plate 21 that can be raised and lowered and stopped at the front end of the hopper, and a lifting drive mechanism 22 for driving the empty barrel loading top plate to lift and lower. The top end of the empty barrel loading top plate 21 is provided with a guide surface 23 inclined forward and downward. In this embodiment, a stepped structure 14 is provided on the side wall of the front end of the hopper 1, and the two ends of the empty barrel loading top plate 21 are provided with corresponding stepped structures with bosses 24 structures that cooperate with them, which are used to limit the displacement stroke of the empty barrel loading top plate 21.

[0030] The lower end of the empty barrel loading top plate 21 is in close contact with the front end of the bottom wall 11 of the hopper, and the main body of the empty barrel loading top plate 21 is provided with a plurality of vertically distributed tooth grooves.

[0031] The empty tube transfer mechanism 3 includes an empty tube translation placement plate 31 arranged close to the outer side surface of the empty tube loading top plate 21 and a translation driving mechanism 32 for driving the empty tube translation placement plate to move horizontally. The top of the empty tube translation placement plate 31 is provided with an arc groove 33 for accommodating cigarette empty tubes, and the rear end of the arc groove 33 is provided with a stop surface 34 and the front end is empty; the arc groove 33 at the top of the empty tube translation placement plate 31 is an arc groove with an inclined section and a straight section on the upper part, which can effectively prevent the cigarette empty tube 4 from falling off.

[0032] In this embodiment, the rear end surface of the empty tube translation placement plate is a plane, and the front end surface of the empty tube loading top plate is a plane, so that the two can move relative to each other to prevent interference. In addition, they can also serve as guide surfaces for moving against each other and stop surfaces to prevent the empty cigarette tube 4 from falling.

[0033] When the empty tube loading top plate is in a high stroke state, the extension line of the guide surface can extend to the top of the arc groove, so that the lifted cigarette empty tube 4 can enter the arc groove 33.

[0034] In this embodiment, the lifting drive mechanism is a pneumatic slide. In other embodiments, an electric slide or an electric screw mechanism may also be used.

[0035] In this embodiment, the translation drive mechanism is an electric control module slide. In other embodiments, a pneumatic slide or an electric screw mechanism may also be used.

[0036] Working principle description:

[0037] A certain amount of empty cigarette tubes 4 are manually placed into the hopper 1. The empty cigarette tubes 4 can be stacked in multiple layers. To ensure accuracy, only one layer can be stacked. The following is an explanation of the stacking of one layer of empty cigarette tubes 4 in conjunction with the accompanying drawings.

[0038] First, the empty tube lifting mechanism 2 is controlled to descend so that the guide surface 23 at the top of the empty tube loading top plate 21 is lowered to be aligned with the bottom wall 11 at the same height. The frontmost cigarette empty tube 4 moves forward a distance under the action of its own gravity and the pressure of the cigarette empty tube 4 behind. The overall width of the empty tube loading top plate 21 is equal to or slightly larger than the diameter of a single cigarette empty tube 4, so that when the empty tube loading top plate 21 moves upward again, only one cigarette empty tube can be carried and lifted by the guide surface 23. At the same time, the rear side surface of the empty tube translation placement plate 31 on the front side serves as a stop surface to prevent the cigarette empty tube 4 from moving further.

[0039] When the empty tube loading top plate 21 moves to the highest position, the lowest position of the front side of the guide surface 23 exceeds the height of the arc groove 33 of the empty tube translation placement plate 31, and the cigarette empty tube 4 loses the stop constraint and enters the arc groove 33 of the empty tube translation placement plate 31 under the action of its own gravity.

[0040] The empty tube transfer mechanism 3 is driven by the translation drive mechanism 32 to transfer the empty cigarette tube 4 to a required work station.

[0041] The transfer direction can be along the axial direction of the empty cigarette tube or along other directions.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the utility model can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the utility model, which should be included in the scope of the technical solution for protection of the utility model.
