Description

Technical Field

[0001] The invention relates to the technical field of residual smoke wind selection and recovery, and in particular to a wind selection and recovery device for residual smoke that is not qualified in sectioning. Background Art

[0002] Cigarettes are tobacco products made by rolling tobacco into strips with cigarette paper, also known as paper cigarettes, cigarettes or cigarette rolls. Since cigarette machines will inevitably produce some cigarettes that do not meet quality requirements during the process of rolling cigarettes, they are collectively referred to as waste cigarettes in the industry. Waste cigarettes are divided into thick and thin, and they will be sent to the waste cigarette processing device that matches the model for cutting and processing, and then the tobacco and rolling paper will be separated by vibration screening and other methods. In the process of processing, it is inevitable that there will be a large number of cigarettes that are not cut successfully, so that the subsequent tobacco separation cannot be achieved. Therefore, it is often necessary to collect these unqualified residual cigarettes again, and separate the thin cigarettes from the thick cigarettes through the wind selection recovery device, so that they can be put into the waste cigarette processing device of their respective models for processing again.

[0003] However, when the existing wind-sorting and recovery devices for residual cigarettes that fail to be cut are actually used, since the wind-sorting and recovery devices often use wind flow to blow towards the concentrated falling cigarettes, and take advantage of the difference in weight between thin and thick cigarettes, the lighter thin cigarettes are blown away and removed, while the heavier thick cigarettes continue to fall due to gravity. However, since a large number of thick and thin cigarettes are concentrated and mixed and fall, they are relatively crowded and dense, and the uniform dispersion of the falling cannot be guaranteed, which makes it difficult for the wind flow to effectively blow away and remove the thin cigarettes. In addition, it is inevitable that a large number of loose tobacco shreds will be detached from the residual cigarettes that fail to be cut and their mixed extrusion, and they will be mixed with the recovered cigarettes during wind sorting, making it difficult to clean and separate them later, and the use effect is not good. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a wind selection and recovery device for residual cigarettes that are not up to standard in cutting. By arranging a dispersing mechanism in the shell body, and cooperating with a feeding assembly, a first receiving channel and a second receiving channel, the residual cigarettes entering the feed hopper can be continuously dropped into each screen cylinder, so that the annularly arranged screen cylinders can be circulated and intermittently received, and the tobacco shreds mixed in the residual cigarettes can continuously drop out through the screen holes on the screen cylinders and enter the second receiving channel, and finally fall into the collecting frame for collection, so as to realize the wind selection and recovery of the tobacco shreds in the residual cigarettes that are not up to standard in cutting; at the same time, as the cigarettes in each screen cylinder fall out at intervals, the lighter and thinner cigarettes in the residual cigarettes can be blown into the first receiving channel and conveyed away through the third conveyor belt, and the heavier and thicker cigarettes fall onto the second conveyor belt by gravity and are conveyed away.

[0051] The material dispersing mechanism is arranged in the housing 1 below the feed hopper 2, and includes a roller 26 rotatably mounted in the housing 1 through a bearing, one end of the roller 26 is connected to a driving mechanism, and a plurality of connecting frames 27 are arranged in a circular array on the outer wall of the roller 26, a rotating rod 30 is rotatably connected to the middle of the outer side of the connecting frame 27 through a bearing, a screen drum 28 is fixed to the top of the rotating rod 30, and a swing mechanism is arranged at the bottom of the rotating rod 30, and an opening 29 is opened on the side of the screen drum 28 relative to the connecting frame 27;

[0052] The driving mechanism includes a second motor 25 fixed to one side of the housing 1 , a first gear 40 is fixed to one end of the roller 26 , and an output end of the second motor 25 extends into the housing 1 and is connected to a second gear 41 meshing with the first gear 40 .

[0053] The material conveying assembly includes a first conveyor belt 3, a second conveyor belt 5 and a third conveyor belt 10. The end of the first conveyor belt 3 is arranged above the feed hopper 2, the second conveyor belt 5 is passed through the bottom end of the shell 1 close to the side of the platform 42, and the second conveyor belt 5 is located below the bulk material mechanism.

[0055] When in use, the unqualified residual cigarettes can be sent to the feed hopper 2 through the first conveyor belt 3, so that the residual cigarettes fall into the shell 1, and the second gear 41 is driven to rotate by the second motor 25, so that the second gear 41 drives the first gear 40 to rotate, and then the first gear 40 drives the roller 26 to rotate, so that the roller 26 can drive each screen drum 28 to rotate through the connecting frame 27. When the opening 29 of the top screen drum 28 faces the feed hopper 2, the cigarettes can fall into the screen drum 28, and then the screen drum 28 drives the cigarettes to continue to rotate, and the next empty screen drum 28 moves to the top position and continues to receive materials. Under the action of this structure, the annular screen drum 2 8 is intermittently received in a cycle, and when the screen cylinder 28 drives the cigarette to rotate, the tobacco mixed in the residual smoke can continuously fall out through the screen holes on the screen cylinder 28, and under the action of the blowing component, the tobacco can be blown toward the platform 42. At this time, the first motor 11 can drive the connecting rod 12 to rotate, so that the connecting rod 12 drives the baffle 13 to rotate, so that the angle of the baffle 13 can be adjusted, so that the baffle 13 is rotated to the top of the first receiving channel 8 to expose the second receiving channel 9 with a large area, and then the tobacco can be blown into the second receiving channel 9 and fall into the collecting frame 18 for collection, so as to realize the wind selection and recovery of tobacco in the residual smoke that fails to be cut;

[0056] As the opening 29 of the rotating screen drum 28 slowly moves downward, the cigarettes in each screen drum 28 can fall out at intervals. At this time, the baffle 13 is controlled to rotate and adjust the angle, so that the first material receiving channel 8 can leak out a large area, and when the baffle 13 contacts the inner wall of the arc-shaped cavity 15, the second material receiving channel 9 can be completely blocked so that it can be used according to needs.

[0059] Support frames 31 are symmetrically arranged at both ends of the connecting frame 27 , a guide groove 32 is opened on the top side of the support frame 31 , and guide columns 33 are fixed to both ends of the bottom side of the screen drum 28 , and the guide columns 33 are slidably fitted in the guide groove 32 .

[0060] When the screen drum 28 receives the material and rotates, the third motor 35 can drive the rotating handle 36 to rotate, so that the rotating handle 36 drives the sliding column 37 to slide back and forth in the sliding groove 39, and then the sliding column 37 can push the limiting column 38 to rotate. Under the circumferential rotation of the rotating handle 36, the limiting column 38 can drive the rotating rod 30 to swing continuously, that is, the rotating rod 30 can drive the screen drum 28 to swing back and forth, so that the cigarettes in the screen drum 28 are shaken and oscillated, which can not only better shake out the tobacco shreds and improve the wind separation effect of the tobacco shreds, but also can evenly distribute the cigarettes in the screen drum 28, so that the cigarettes are more evenly dispersed when they fall out of the screen drum 28, further improving the selection effect of separating thick and thin cigarettes;
