[0034] Refer to Figure 1 As shown, an embodiment of the present application provides a secondary recovery device 100, which can be used for the recovery of tobacco shreds in the process of waste cigarette treatment to reduce the tobacco shred content in cigarette paper and improve the recovery rate of tobacco shreds. It should be noted that the secondary recovery device 100 provided in this application is applicable to various recovery scenarios. For the sake of easy understanding, the processing scenario of tobacco shred recovery is taken as an example for illustration.

[0035] Specifically, the secondary recovery device 100 includes a processing device 110, a first conveying device 120 and a second conveying device 130. Among them, the processing device 110 can be used to crush waste cigarettes to form a mixed material of cigarette paper and tobacco shreds, and recover the tobacco shreds in the mixed material. The input end of the first conveying device 120 is connected to the output end of the processing device 110 to convey the cigarette paper to the first conveying device 120 after the tobacco shreds are recovered by the processing device 110. The input end of the second conveying device 130 is connected to the output end of the first conveying device 120, and the output end of the second conveying device 130 is connected to the input end of the processing device 110 to receive the cigarette paper that has undergone primary tobacco shred recovery from the first conveying device 120. When there is still a certain content of tobacco shreds in the cigarette paper, the second conveying device 130 conveys the cigarette paper that has undergone primary tobacco shred recovery to the processing device 110 again for secondary tobacco shred recovery to improve the recovery rate of tobacco shreds, reduce the tobacco shred content in the cigarette paper, and reduce tobacco shred waste.

[0036] It should be noted that in this application, the number of times of tobacco shred recovery is not limited to two times in the above embodiment, and can be reasonably selected according to the tobacco shred content in the cigarette paper. For example, when the tobacco shred content in the cigarette paper still does not meet the industry requirements, the second conveying device 130 can continue to convey the cigarette paper to the processing equipment for three times, four times and other tobacco shred recovery treatments.

[0037] Exemplarily, the processing device 110 may be a drum - type shredded tobacco recycling device, such as the tobacco shred recycling device provided in the patent document with the applicant Changde Ruihua Manufacturing Co., Ltd. and the publication number CN209449661U. The tobacco shred recycling device cited in this embodiment is only for illustrative reference to meet the functions of crushing waste tobacco and recycling tobacco shreds, but is not limited to the above - cited device. Other devices with the same functions can be applied to this application, and no specific limitation is made here.

[0038] In some embodiments, the secondary recycling device 100 further includes a switching device 140 and a third conveying device 150. The input end of the third conveying device 150 is connected to the output end of the first conveying device 120, and the output end of the third conveying device 150 is connected to the input end of the second conveying device 130 to receive the cigarette paper from the first conveying device 120 and transfer it to the second conveying device 130. The switching device 140 is installed at the output end of the first conveying device 120 and controls the output direction of the cigarette paper to achieve the connection or blockage of material conveyance between the first conveying device 120 and the third conveying device 150.

[0039] Specifically, the processing device 110, the first conveying device 120, the third conveying device 150, and the second conveying device 130 are arranged perpendicular to each other in pairs to form a circulating conveying path. The output end of the processing device 110 is above the input end of the first conveying device 120 in the direction of gravity. The input end of the third conveying device 150 and the switching device 140 are both provided below the output end of the first conveying device 120. The input end of the second conveying device 130 is provided below the output end of the third conveying device 150, and the input end of the processing device 110 is provided below the output end of the first conveying device 120, so that the cigarette paper falls onto the next device under the action of gravity.

[0040] After the processing device 110 recycles the tobacco shreds, the cigarette paper is output from the output end of the processing device 110. Under the action of gravity, the cigarette paper falls onto the first conveying device 120, is output by the first conveying device 120, and the switching device 140 guides the scattering direction of the cigarette paper so that the cigarette paper falls onto the third conveying device 150. When only the primary tobacco shred recycling is carried out or there is still a large amount of tobacco shreds in the cigarette paper, the switching device 140 guides and conveys the cigarette paper to the third conveying device 150 and finally enters the processing device 110 for secondary tobacco shred recycling. When the tobacco shred content in the cigarette paper meets the standard, the switching device 140 blocks the material connection between the first conveying device 120 and the third conveying device 150 to prevent the cigarette paper from entering the processing device 110 again, facilitating the collection and storage of the cigarette paper.

[0041] In some embodiments, the secondary recycling device 100 further includes a collecting device 160. The collecting device 160 is connected to the output end of the first conveying device 120. Under the control of the switching device 140, the first conveying device 120 conveys the cigarette paper after primary tobacco shred recycling to the second conveying device 130, and conveys the cigarette paper after secondary tobacco shred recycling to the collecting device 160.

[0042] Specifically, after secondary tobacco shred recycling, the tobacco shred content in the cigarette paper meets the standard. The cigarette paper falls from the output end of the first conveying device 120 and falls into the collecting device 160 under the guidance of the switching device 140 for recycling of the cigarette paper.

[0043] Exemplarily, the collecting device 160 can be a paper press, a collecting box, a collecting bag, etc. to meet the storage of the cigarette paper.

[0044] In some embodiments, a fourth conveying device 170 is provided between the collecting device 160 and the first conveying device 120. The input end of the fourth conveying device 170 is connected to the output end of the first conveying device 120, and the output end of the fourth conveying device 170 is connected to the collecting device 160.

[0045] Specifically, the input end of the fourth conveying device 170 is also located below the output end of the first conveying device 120, and the fourth conveying device 170 is arranged in parallel with the third conveying device 150, so that during the scattering process of the cigarette paper, the switching device 140 guides the cigarette paper to the corresponding conveying device according to the number of times of tobacco shred recycling of the cigarette paper.

[0046] Exemplarily, the first conveying device 120, the second conveying device 130, the third conveying device 150 and the fourth conveying device 170 can all be belt conveyors or screw conveyors, as long as they can meet the conveying of the cigarette paper.

[0047] Continue to refer to Figure 2 and Figure 3 As shown, in some embodiments, the switching device 140 includes a first corner turner 141, a first rotating shaft 142 and a guide plate 143. Among them, the first rotating shaft 142 is connected to the first corner turner 141 to rotate at an angle under the drive of the first corner turner 141. One side of the guide plate 143 is mounted on the first rotating shaft 142 to follow the angle adjustment of the first rotating shaft 142, so as to limit the conveying direction of the cigarette paper by the rotation of the guide plate 143 when receiving the cigarette paper output by the first conveying device 120.

[0048] Specifically, when the cigarette paper falls from the output end of the first conveying device 120, it contacts the surface of the guide plate 143 and enters different conveying devices under the guidance of the guide plate 143. When the cigarette paper only undergoes primary tobacco shred recycling or the tobacco shred content in the cigarette paper does not meet the standard, through the angle adjustment of the first corner device 141, the end of the guide plate 143 far from the first rotating shaft 142 faces the input end of the third conveying device 150, so as to guide the cigarette paper to the third conveying device 150 and finally enter the processing device 110 for secondary tobacco shred recycling. When the cigarette paper undergoes secondary tobacco shred recycling, the first corner device 141 controls the end of the guide plate 143 far from the first rotating shaft 142 to face the input end of the fourth conveying device 170, so as to guide the cigarette paper to the fourth conveying device 170 and finally enter the collection device 160 to complete the recycling process of the cigarette paper.

[0049] Continue to refer to Figure 6 As shown, in some embodiments, the secondary recycling device 100 further includes a material level detector 190, which is installed on the second conveying device 130 and is used to detect the height of the cigarette paper on the second conveying device 130.

[0050] Specifically, the second conveying device 130 can cache the cigarette paper. During the process of the cigarette paper falling into the second conveying device 130, the second conveying device 130 can pause the conveying, so that the cigarette paper accumulates on the second conveying device 130. When the material level detector 190 detects that the cigarette paper reaches the preset height value, the second conveying device 130 conveys the cigarette paper to the processor to facilitate the batch processing of the cigarette paper and improve the tobacco shred recycling efficiency of the processing device 110.

[0051] Exemplarily, the material level detector 190 can be a height sensor and is electrically connected to the motor of the second conveying device 130, so as to obtain the stacking height of the cigarette paper, send the signal to the control system, and then drive the motor to operate, and the second conveying device 130 performs the conveying operation.

[0052] In some embodiments, there are multiple material level detectors 190, and each material level detector 190 is arranged at intervals along the conveying direction of the second conveying device 130. The second conveying device 130 limits the traveling distance of the conveyor belt according to the height of the cigarette paper detected by each material level detector 190.

[0053] Exemplarily, taking the input end of the second conveying device 130 as the front end and the output end of the second conveying device 130 as the rear end, multiple material level detectors 190 are arranged on the second conveying device 130 from front to back in sequence to judge the storage amount of the cigarette paper at different positions of the second conveying device 130.

[0054] Specifically, when the cigarette paper falls from the third conveying device 150 into the second conveying device 130, since the second conveying device 130 stops operating, the cigarette paper falls to the front end of the second conveying device 130 and accumulates. At this time, when the level detector 190 at the front end detects that the cigarette paper reaches the maximum height, the second conveying device 130 conveys a set distance backward, so that the part without cigarette paper is located below the output end of the third conveying device 150, and continues to receive the cigarette paper. This process is repeated until all the level detectors 190 detect that the height of the cigarette paper reaches the preset value, and then the second conveying device 130 conveys all the cigarette paper to the feed hopper of the processing device 110.

[0055] In some embodiments, the secondary recovery device 100 further includes a blocking device 180, which is installed at the output end of the second conveying device 130 to limit the flow of cigarette paper on the second conveying device 130.

[0056] Specifically, the blocking device 180 is arranged at the output end of the second conveying device 130. Thus, during the conveying process of the second conveying device 130, the cigarette paper on the second conveying device 130 is blocked, causing the cigarette paper to accumulate on the second conveying device 130 until the set storage amount of cigarette paper on the second conveying device 130 is reached. Then the blocking device 180 opens, and the cigarette paper enters the feed hopper of the processing device 110 under the conveying of the second conveying device 130.

[0057] Continue to refer to Figure 4 and Figure 5 As shown in, in some embodiments, the blocking device 180 includes a second corner turner 181, a second rotating shaft 182 and a baffle 183. Among them, the second rotating shaft 182 is connected to the second corner turner 181 to rotate under the drive of the second corner turner 181. One side of the baffle 183 is installed on the second rotating shaft 182 to rotate following the second rotating shaft 182. By changing the angle of the baffle 183, the flow of cigarette paper on the second conveying device 130 is limited.

[0058] Specifically, the bottom of the baffle 183 is flush with the surface of the conveyor belt of the second conveying device 130 and rotates under the action of the second corner turner 181. When the baffle 183 is perpendicular to the conveying direction of the second conveying device 130, the blocking device 180 is in the closed state to block the cigarette paper on the second conveying device 130. When the baffle 183 is parallel to the conveying direction of the second conveying device 130, the blocking device 180 is in the open state, and the cigarette paper on the second conveying device 130 can enter the processing device 110 for secondary tobacco shred recovery.

[0059] The embodiment of the present application also provides a waste cigarette recovery system, including the secondary recovery device 100 in any of the above embodiments.

[0060] In this embodiment, the secondary recycling device 100 in any of the above embodiments is included. Therefore, all the beneficial effects of the secondary recycling device 100 in any of the above embodiments are achieved, and they will not be elaborated here one by one.

[0061] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0062] The above-described embodiments only represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
