[0052] As Figures 1 to 4As shown, some embodiments of the present disclosure provide a device for recycling tobacco and burst beads, which comprises a conveying line 3 and a plurality of workstations.

[0053] The conveying line 3 has a working surface 30 for conveying cigarettes 6. The plurality of workstations are arranged on the conveying line 3. The plurality of workstations comprise a tobacco separation workstation 2 and a burst bead separation workstation 5, the tobacco separation workstation 2 comprising a tobacco separation device for separating tobacco 61 in a paper tube 64 of the cigarette 6 from the cigarette 6, and the burst bead separation workstation 5 comprising a burst bead separation device for separating a burst bead 62 embedded in a filter 63 of the cigarette 6 from the cigarette 6.

[0054] In the present disclosure, the positions of the tobacco separation workstation 2 and the burst bead separation workstation 5 are not strictly limited. Figure 1 In the embodiment as shown, the tobacco separation workstation 2 can be arranged upstream of the burst bead separation workstation 5, and the tobacco separation is performed first and then the burst bead separation; in some embodiments not shown, the tobacco separation workstation 2 can also be arranged downstream of the burst bead separation workstation 5, and the burst bead separation is performed first and then the tobacco separation.

[0055] Some embodiments of the present disclosure provide a device for recycling tobacco and burst beads, in which the tobacco separation device can automatically separate the tobacco, and the burst bead separation device can automatically separate the burst beads, so that the separation and recycling of the tobacco and the burst beads in the waste cigarette are realized in the same device, the recycling of the raw materials of the cigarette is realized, and the efficiency of the tobacco separation operation and the burst bead separation operation is improved, thereby reducing the cost and increasing the efficiency.

[0056] In some embodiments, as shown in Figure 2 As shown, the tobacco separation device comprises a jet nozzle 21, which is configured to spray air into the cigarette 6 to blow the tobacco 61 out of the cigarette 6.

[0057] Figure 1 And Figure 2 In the embodiment as shown, the filter end of the cigarette 6 is arranged close to the jet nozzle 21, and the airflow sprayed by the jet nozzle 21 acts on the tobacco 61 in the paper tube 64 through the filter 63.

[0058] Based on the above arrangement, the efficiency of separating the tobacco by the jet method is high, and the airflow will not cause damage to the tobacco and the burst beads.

[0059] In some embodiments, as shown in Figure 2 As shown, the jet direction of the jet nozzle 21 is parallel to the working surface 30 and perpendicular to the conveying direction of the conveying line 3.

[0060] Considering that the cigarette is generally placed on the working surface, when the cigarette 6 is conveyed to the tobacco separation workstation 2 by the conveying line 3, the jet nozzle 21 can spray air along the axial direction of the cigarette 6, which can improve the efficiency of blowing the tobacco out of the cigarette and reduce the disturbance of the airflow to the position of the cigarette.

[0061] In order to separate the tobacco from the cigarettes more thoroughly and improve the recovery rate of the tobacco, in some embodiments, the plurality of workstations comprises at least two tobacco separating workstations 2 arranged in series along the conveying direction of the conveying line 3.

[0062] In some embodiments, as shown in Figure 4 The ejection component 51 is movably arranged relative to the working surface 30 and is configured to eject the balloon 62 out of the filter 63.

[0063] The ejection force of the ejection component is appropriate to be able to press into the filter and push the balloon out, without crushing the balloon. In the above embodiment, the ejection component 51 is able to extend into the filter 63 and act on the balloon 62, thereby ejecting the balloon out of the filter and achieving separation of the balloon.

[0064] In some embodiments, as shown in Figure 4 The moving direction of the ejection component 51 is parallel to the working surface 30 and perpendicular to the conveying direction of the conveying line 3.

[0065] Figure 1 In the embodiment shown in Figure 4 The filter end of the cigarette 6 is arranged close to the ejection component 51, and the required stroke of the ejection component is shorter, facilitating ejection of the balloon by the ejection component.

[0066] In some embodiments, as shown in Figure 1 and Figure 3 The plurality of workstations further comprises a cigarette cutting workstation 4 located upstream of the balloon separating workstation 5 along the conveying direction of the conveying line 3, and the cigarette cutting workstation 4 comprises a cutter 41 configured to cut the filter 63 at a position separated from the balloon 62 by a preset distance.

[0067] The preset distance can be specifically set according to the position of the cigarette on the working surface, the size and position of the filter, the size and position of the balloon, and the type and size of the cutter, as long as the cut position of the filter is close to the balloon and the balloon is not damaged.

[0068] Based on the above arrangement, the cutter can cut a part of the filter, and the balloon is located in the remaining part of the filter, and the position of the balloon is closer to the cut surface than the original axial end surface of the filter. The required stroke for separating the balloon from the filter is shorter, which is beneficial to improve the separation efficiency of the balloon and reduce the probability of damaging the balloon during the separation process. When the cutter cuts the filter, it can avoid the position of the balloon and will not damage the balloon.

[0069] Figure 1 In the embodiment shown in Figure 3 The cutter 41 can be a rotary cutter, and the rotary axis of the rotary cutter can be parallel to the working surface 30 and perpendicular to the conveying direction of the conveying line 3.

[0070] In some embodiments, as shown in Figure 3 The working surface 30 is provided with an avoidance groove 32 corresponding to the position of the cutter 41, which is configured to provide space for the working surface 30 to avoid the bottom edge of the cutter 41.

[0071] By providing the avoidance groove 32, the collision between the bottom edge of the cutter and the working surface can be avoided, and the cutter can completely cut off the filter tip, avoiding the part that needs to be cut off remaining on the part embedded with the balloon, affecting the separation of the balloon.

[0072] In some embodiments, as shown in Figure 1 The tobacco separation station 2, the cigarette cutting station 4, and the balloon separation station 5 are sequentially arranged along the conveying direction of the conveying line 3.

[0073] In the above embodiments, the device for recovering cigarettes and balloons first separates the tobacco from the paper tube to recover the tobacco, then cuts the filter tip to separate the balloon, and finally separates the balloon from the cut filter tip to recover the balloon.

[0074] In some embodiments, the tobacco separation station 2, the cigarette cutting station 4, and the balloon separation station 5 are arranged on the same side of the conveying line 3.

[0075] In the above embodiments, the other side of the conveying line opposite to the tobacco separation station, the cigarette cutting station, and the balloon separation station can be provided with corresponding tobacco collection devices and balloon collection devices to realize the reasonable layout of the separation device and the recovery device.

[0076] In some embodiments, as shown in Figures 1 to 4 The working surface 30 is provided with a plurality of accommodation grooves 31 configured to accommodate the cigarettes 6. The two ends of the extension direction of the accommodation grooves 31 are provided with axial limiting components 33 extending in a direction perpendicular to the working surface 30, which are configured to limit the displacement of the cigarettes 6 along the extension direction of the accommodation grooves 31.

[0077] In the above embodiments, the accommodation grooves 31 can be circular arc grooves matched with the shape of the cigarettes 6. The accommodation grooves can limit the movement of the cigarettes along the conveying direction of the conveying line, and the axial limiting components can limit the movement of the cigarettes along the axial direction. The accommodation grooves and the axial limiting components can jointly limit the position of the cigarettes on the conveying line, thereby avoiding the displacement of the cigarettes during the separation of the tobacco and the balloon, affecting the separation effect.

[0078] In some embodiments, at least one of the plurality of stations further comprises a vertical limiting component arranged above the working surface 30 and configured to limit the displacement of the cigarettes 6 in a direction perpendicular to the working surface 30.

The vertical limiting component can be a limiting plate.

[0080] In the above embodiment, the vertical limiting component can limit the movement of the cigarette in the vertical direction, and the accommodating groove, the axial limiting component, and the vertical limiting component can jointly limit the position of the cigarette on the conveying line, thereby further avoiding displacement of the cigarette during tobacco-segmenting and balloon-separating, and affecting the separating effect.

[0081] In some embodiments, as shown in Figure 1 As shown, the plurality of stations further comprises a cigarette-providing station 1, which is arranged at the inlet of the conveying line 3 and is configured to place the cigarettes 6 on the working face 30.

[0082] In some embodiments, the cigarette-providing station 1 comprises a hopper 11 and a cigarette-feeding device 12, which is in communication with the outlet of the hopper 11 and has at least one cigarette-feeding passage arranged inside, each of which is configured to place one cigarette 6 on the working face 30 at a time.

[0083] In order to improve the placing efficiency of the cigarettes, Figure 1 In the illustrated embodiment, the inside of the cigarette-feeding device 12 is provided with a plurality of cigarette-feeding passages, so that the cigarette-providing station can simultaneously stack a plurality of cigarettes on the working face of the conveying line.
