[0002] Reconstructed raw materials, including reconstructed tobacco leaves and reconstructed stem shreds, are waste tobacco stems, tobacco dust and low-quality tobacco leaves produced during cigarette production, which are processed in series to produce reconstructed tobacco leaves with quality close to or even better than natural tobacco leaves. At present, during the storage of finished reconstructed raw materials, the reconstructed raw materials are stacked on top of each other, and due to the effect of gravity, there is a common problem of adhesion, and the adhesion rate of reconstructed raw materials increases with the increase of storage time.

[0038] Embodiment 1

[0039] The present embodiment provides a reconstituted tobacco raw material loosening device, which can be used in the storage process of the reconstituted tobacco raw material to reduce the agglomeration behavior of the reconstituted tobacco raw material and ensure the product quality.

[0040] Please refer to Figure 1-2 The reconstituted tobacco raw material loosening device provided in this embodiment includes two conveying mechanisms 1 and a flipping mechanism 3. The two conveying mechanisms 1 are arranged at intervals along the X direction. The conveying mechanism 1 includes a conveyor belt 11. The two ends of the reconstituted raw material finished box 2 in the X direction are respectively supported by the conveyor belts 11 of the two conveying mechanisms 1. The conveyor belt 11 is used to transport the reconstituted raw material finished box 2 to the flipping station along the Y direction. The X direction is perpendicular to the Y direction. The flipping mechanism 3 includes a lifting plate 31, a lifting drive unit 32 and a flipping assembly 33. The lifting plate 31 is arranged between the two conveying mechanisms 1, and the output end of the lifting drive unit 32 is connected to the lifting plate 31.

[0041] When the two conveying mechanisms 1 convey the reconstructed raw material finished box 2 to the flipping station along the Y direction, the lifting drive unit 32 drives the lifting plate 31 to support the reconstructed raw material finished box 2 to rise above the conveyor belt 11, and the flipping assembly 33 is used to push the reconstructed raw material finished box 2 on the lifting plate 31 to flip. Since the lifting drive unit 32 drives the lifting plate 31 to support the reconstructed raw material finished box 2 to rise above the conveyor belt 11, the reconstructed raw material finished box 2 is separated from the support of the conveyor belt 11, and the stability of the reconstructed raw material finished box 2 supported by the support is reduced, which facilitates the flipping assembly 33 to flip the reconstructed raw material finished box 2. When the reconstructed raw material finished box 2 flips 90°, the force between the reconstructed tobacco raw materials stacked therein is converted from the gravity in the vertical direction to the friction in the vertical direction, thereby changing the force condition of the reconstructed tobacco raw materials and alleviating the adhesion problem caused by gravity during the storage of the reconstructed tobacco raw materials. Furthermore, the vibration generated by the reconstructed raw material finished product box 2 falling from the lifting plate 31 to the transmission belt 11 can further loosen the reconstructed tobacco raw material in the reconstructed raw material finished product box 2.

[0042] In addition, the entire turning process does not require stopping the conveying mechanism 1 and opening the reconstituted raw material finished product box 2, which can avoid the reconstituted tobacco raw material from contacting the external environment to ensure product quality and avoid directly loosening the reconstituted tobacco raw material to increase the degree of crushing of the reconstituted tobacco raw material.

[0043] For further information, please refer to Figure 1In this embodiment, the lifting plate 31 is connected to the output end of the lifting drive unit 32 by a first rotating shaft, and the flip assembly 33 includes a linear drive unit 331, and the output end of the linear drive unit 331 is connected to the lifting plate 31 by a second rotating shaft. The first rotating shaft and the second rotating shaft are both extended along the X direction and arranged at intervals along the Y direction. By controlling the different extension speeds of the output end of the linear drive unit 331 and the output end of the lifting drive unit 32 during operation, the lifting plate 31 is rotated around the first rotating shaft, so that the lifting plate 31 is tilted relative to the Y direction, so that the recycled raw material finished box 2 located on the lifting plate 31 falls under the action of gravity and flips at least 90°. Exemplarily, the lifting drive unit 32 and the linear drive unit 331 are both cylinders. In other embodiments, the lifting drive unit 32 and the linear drive unit 331 can also use existing linear drive mechanisms such as linear motors or electric push rods, which are not listed here one by one.

[0044] For example, please refer to Figure 1 The second rotating shaft is located at the upstream edge of the lifting plate 31 along the Y direction. During the process of the lifting drive unit 32 driving the lifting plate 31 to support the recycled raw material finished product box 2 to rise, the extension speed of the output end of the linear drive unit 331 is greater than the extension speed of the output end of the lifting drive unit 32, so that the output end of the linear drive unit 331 is higher than the output end of the lifting drive unit 32 in the vertical direction, so that the lifting plate 31 rotates around the rotating shaft.

[0045] It should be noted that, in other embodiments, the second rotating axis can also be set along the Y direction at the downstream edge of the lifting plate 31, and the extension speed of the output end of the linear drive unit 331 is smaller than the extension speed of the output end of the lifting drive unit 32, so that the output end of the linear drive unit 331 is lower than the output end of the lifting drive unit 32 in the vertical direction.

[0046] For further information, please refer to Figure 1 The conveying mechanism 1 further includes a conveying support 12, a motor 13 and two pulleys 14 both rotatably connected to the conveying support 12. The two pulleys 14 are arranged at intervals along the Y direction, and the two pulleys 14 are connected through the conveyor belt 11. The output end of the motor 13 is connected to one of the pulleys 14 to drive the pulley 14 to rotate. In order to avoid the unstable support of the conveyor belts 11 on the recycled raw material finished box 2 caused by the different running speeds of the two conveyor belts 11, the two transmission mechanisms are exactly the same, so that the edge of the recycled raw material finished box 2 along the X direction is always parallel to the X direction during the conveying process, so as to facilitate the subsequent flipping thereof.

[0047] For further information, please refer to Figure 2In order to prevent one end of the recycled raw material finished box 2 in the X direction from falling into the gap between the two conveyor belts 11 during the flipping process, the width of the recycled raw material finished box 2 along the X direction is L1, and the distance between the inner edges of the conveyor belts 11 of the two conveying mechanisms 1 is L2, L1≥2L2. Since L1≥2L2, during the conveying process, the conveyor belt 11 has a stable supporting effect on both ends of the recycled raw material finished box 2 in the X direction.

[0048] For further information, please refer to Figure 2 In order to improve the working accuracy of the turning mechanism 3, the reconstituted tobacco raw material loosening device further includes a position detection unit 4, which is used to detect whether a reconstituted raw material finished product box 2 has arrived at the turning station. It should be noted that the position detection unit 4 can be an existing position detector such as a photoelectric sensor or an infrared sensor, which will not be listed here one by one.

[0049] For further information, please refer to Figure 2 In order to prevent the reconstituted raw material finished box 2 from separating from the conveyor belt 11 along the X direction, the reconstituted tobacco raw material loosening device also includes two baffles 5 arranged at intervals along the X direction, the top surface of the baffle 5 is higher than the upper surface of the conveyor belt 11, and the reconstituted raw material finished box 2 on the conveyor belt 11 is limited between the two baffles 5.

[0050] For details, please refer to Figure 2 To prevent one end of the recycled raw material finished product box 2 from falling into the gap between the two conveyor belts 11, the distance between the two baffles 5 is L3, L1<L3, and the distance between the baffle 5 on one side of the lifting plate 31 in the X direction and the inner edge of the conveyor belt 11 on the other side of the lifting plate 31 in the X direction is L4, L1>L4.

[0051] Since L4<L1<L3, the baffle 5 can limit the reconstructed raw material finished box 2, and the reconstructed raw material finished box 2 will not have a large positional displacement during the flipping process due to the wide interval between the two baffles 5, thereby preventing one end of the reconstructed raw material finished box 2 from falling into the gap between the two conveying mechanisms 1 during flipping, so that the reconstructed tobacco raw material loosening device can flip multiple reconstructed raw material finished boxes 2 in turn.

[0052] In this embodiment, a turnover mechanism 3 is provided to make the reconstituted raw material finished box 2 turn over at least 90°. In other embodiments, a plurality of turnover mechanisms 3 may be provided at intervals along the Y direction to continuously turn over the reconstituted raw material finished box 2 during the conveying process, and the problem of adhesion between the reconstituted tobacco raw materials is improved by continuously changing the stress conditions between the reconstituted tobacco raw materials inside the reconstituted raw material finished box 2, so as to reduce the agglomeration rate of the reconstituted tobacco raw materials during storage without unpacking the package.

[0053] Embodiment 2

[0054] like Figure 3-4 As shown, the reconstituted tobacco raw material loosening device provided in this embodiment can also use other turning components 33. For details, please refer to Figure 3 The flipping assembly 33 includes a linear drive unit 331 and a push plate 332. The push plate 332 is located upstream of the lifting plate 31 along the Y direction and is spaced apart from the lifting plate 31 along the Y direction. The push plate 332 can act on the bottom of the recycled raw material finished product box 2 at the flipping station. The output end of the linear drive unit 331 is connected to the push plate 332, which is used to drive the push plate 332 to move linearly so that the push plate 332 pushes the recycled raw material finished product box 2 upward.

[0055] Exemplarily, the output end of the linear drive unit 331 is arranged obliquely relative to the Y direction. After the lifting drive unit 32 drives the lifting plate 31 to support the recycled raw material finished product box 2 to rise to a suitable position and stop, the linear drive unit 331 drives the push plate 332 to push the bottom edge of the recycled raw material finished product box 2 in an oblique upward direction, so that the recycled raw material finished product box 2 falls from the lifting plate 31 and flips at least 90 degrees. It should be noted that in other embodiments, the output end of the linear drive unit 331 can also be arranged in the vertical direction.

[0056] For further information, please refer to Figure 5 In order to enhance the loosening effect of the reconstituted tobacco raw material loosening device, an elastic element 6 extending in the vertical direction is arranged between the output end of the lifting drive unit 32 and the lifting plate 31, and the lifting plate 31 is slidably connected with the output end of the lifting drive unit 32 in the vertical direction. When the lifting drive unit 32 drives the lifting plate 31 to rise, the output end of the lifting drive unit 32 drives the elastic element 6 and the lifting plate 31 to move forward at the same speed. When the output end of the lifting drive unit 32 stops driving, the elastic element 6 and the lifting plate 31 have inertia, so that the elastic element 6 is elastically deformed again. Under the action of the elastic restoring force of the elastic element 6, the lifting plate 31 and the reconstituted raw material finished box 2 above it vibrate up and down, and the reconstituted tobacco raw material in the reconstituted raw material finished box 2 is further loosened by the vibration effect, so as to enhance the loosening effect of the reconstituted tobacco raw material loosening device. It should be noted that the elastic element 6 can be a spring.

[0057] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there will be changes in the specific implementation methods and application scopes. The contents of this specification should not be understood as limiting the present invention.
