DETAILED DESCRIPTION

[0035] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0036] Reference is made to the accompanying Figure 1 - the accompanying Figure 7 A tobacco leaf piece-by-piece separating device comprises a body 1, a feeding mechanism 2 and a separating mechanism 3. The body 1 is provided with a bracket 10, and the bracket 10 is provided with a first slot 101. The feeding mechanism 2 is installed on the bracket 10 and can convey stacked tobacco leaves in the first slot 101. The separating mechanism 3 comprises a dial 31 and a servo motor 32. The dial 31 is rotatably arranged at the end of the first slot 101, and the circumferential edge of the dial 31 is arrayed with a plurality of dial gears 310, each of which is designed to correspond to a single tobacco leaf. The servo motor 32 is installed on the bracket 10 and is drivingly connected with the dial 31.

[0037] Specifically, before use, the stacked tobacco leaves are moved to the front end of the first slot 101 by a mechanical hand (not shown in the figure) or other feeding equipment, and then the feeding mechanism 2 and the servo motor 32 are started at the same time. The feeding mechanism 2 will extrude and convey the stacked tobacco leaves, so that the multiple tobacco leaves entering the first slot 101 are laid out in a straight line. When the feeding mechanism 2 conveys the first tobacco leaf into the end of the first slot 101, the servo motor 32 synchronously drives the dial 31 to rotate, so that the dial gear 310 corresponding to the tobacco leaf is driven to separate the tobacco leaf from the first slot 101. Since one dial gear 310 corresponds to one tobacco leaf, as the feeding mechanism 2 continuously conveys the tobacco leaves to the end of the first slot 101, the rotating dial 31 will also drive the dial gear 310 to continuously separate the tobacco leaves at the end of the first slot 101.

[0038] In summary, the present application provides a passage for tobacco leaves by designing a first slot 101 on the bracket 10 of the machine body 1, installs a feeding mechanism 2 on the bracket 10 for extruding and driving the suspended tobacco leaves to move along the first slot 101, and finally drives the ratchet wheel 31 by the servo motor 32 of the separating mechanism 3, so that the ratchet teeth 310 drive the single tobacco leaf to separate from the end of the first slot 101, thereby realizing the piece-by-piece discrete operation of the tobacco leaves, and the degree of automation is high, which can effectively make up for the uneven experience of the staff, avoid the overlapping of tobacco leaves, damage of tobacco leaves and other situations, thereby improving the production efficiency and reducing the failure rate.

[0039] It should be noted that the separated tobacco leaves can be first automatically identified and processed by an image + AI system to screen out qualified tobacco leaves for processing, or directly placed in other equipment for corresponding processing, and since the types of corresponding processes are various, the present application does not limit them.

[0040] Referring to the accompanying drawings Figure 6 - the accompanying drawings Figure 9 The present application also includes a feeding mechanism 4 and a throwing and separating mechanism 5 which has the same structure as the separating mechanism 3, and the bracket 10 is also provided with a second slot 102 for the tobacco leaves to pass through; the throwing and separating mechanism 5 is installed on the bracket 10, and the first and second ends of the second slot 102 are located at the separating mechanism 3 and the throwing and separating mechanism 5, respectively; the feeding mechanism 4 is installed on the bracket 10 and can convey the tobacco leaves in the second slot 102, and the running speed of the feeding mechanism 4 is lower than that of the throwing and separating mechanism 5.

[0041] Specifically, during use, the feeding mechanism 2, the separating mechanism 3, the feeding mechanism 4 and the throwing mechanism are started at the same time; when the feeding mechanism 2 conveys the tobacco leaves to the end of the first slot 101, the separating mechanism 3 drives the single tobacco leaf to the first end of the second slot 102, at this time, the feeding mechanism 4 conveys the tobacco leaves along the second slot 102 to the throwing and separating mechanism 5; since the running speed of the feeding mechanism 4 is lower than that of the throwing and separating mechanism 5, when the single tobacco leaf contacts the throwing and separating mechanism 5, it will be thrown out quickly, and the subsequent tobacco leaves in the second slot 102 will fall behind slightly, thereby pulling apart the relative distance between the front and rear tobacco leaves, avoiding the overlapping of the two tobacco leaves after they are separated from the throwing and separating mechanism 5.

[0042] Referring to the accompanying drawings Figure 6 - the accompanying drawings Figure 9 The present application also includes a feeding mechanism 4 and a throwing and separating mechanism 5 which has the same structure as the separating mechanism 3, and the bracket 10 is also provided with a second slot 102 for the tobacco leaves to pass through; the throwing and separating mechanism 5 is installed on the bracket 10, and the first and second ends of the second slot 102 are located at the separating mechanism 3 and the throwing and separating mechanism 5, respectively; the feeding mechanism 4 is installed on the bracket 10 and can convey the tobacco leaves in the second slot 102, and the running speed of the feeding mechanism 4 is lower than that of the throwing and separating mechanism 5.

[0043] Specifically, when the tobacco leaves pass through the throwing mechanism 5 to the first end of the third slot 103, the discharging mechanism 6 can transport the single tobacco leaves thrown along the third slot 103 to the outside, thereby improving the stability of the single tobacco leaves; and the running speed of the discharging mechanism 6 is not lower than the running speed of the throwing mechanism 5, so that the conflict between the discharging mechanism 6 and the throwing mechanism 5 can be avoided to prevent the tobacco leaves from being damaged.

[0044] Referring to the accompanying drawings Figure 6 - the accompanying drawings Figure 9 The feeding mechanism 2 and the discharging mechanism 6 are various in type, and the present application does not limit the same. For the convenience of understanding, the feeding mechanism 2 in the embodiment includes the first belt 21 and the first power part 22. The first belt 21 is provided with two roots and is symmetrically arranged on both sides of the first slot 101. A first clamping groove 20 corresponding to the first slot 101 is formed between the two first belts 21 to orderly arrange the stems of the tobacco leaves. The first power part 22 is installed on the support 10 and is synchronously drivenly connected with the two first belts 21. The discharging mechanism 6 is the same in structure as the feeding mechanism 2.

[0045] Specifically, in use, the first driving part is started to drive the two first belts 21 to synchronously run. Since the spacing of the first clamping groove 20 is limited, the number of the tobacco leaves entering is limited, so that the stacked tobacco leaves are sequentially arranged and moved along the direction of the end of the first slot 101 until being separated one by one by the separating mechanism 3. Similarly, when the separated single tobacco leaves are driven by the throwing mechanism 5 to enter the discharging mechanism 6, the discharging mechanism 6 also stably transports the single tobacco leaves.

[0046] Referring to the accompanying drawings Figure 9 The first power part 22 includes the first wheel set 221 and the first driving piece 222. The first wheel set 221 is provided with two sets and is respectively installed on both sides of the first slot 101. The first wheel set 221 includes the first driving wheel 2211 and the first auxiliary wheel 2212. The first driving wheel 2211 is provided with at least two and is respectively rotatably installed on both ends of one side of the first slot 101. The first auxiliary wheel 2212 is provided with a plurality of and is rotatably installed on one side of the first slot 101. The first belt 21 is wound on the two first driving wheels 2211 and the plurality of first auxiliary wheels 2212. The first driving piece 222 is installed on the support 10 and is synchronously drivenly connected with the first driving wheels 2211 of the two first wheel sets 221.

[0047] Specifically, in use, the first driving piece 222 drives the first driving wheel 2211 to rotate, thereby synchronously driving the two first belts 21 to move.

[0048] It should be noted that, regarding the first driving member 222, a motor or other structure with driving ability can be adopted, and in the embodiment, the motor is taken as an example, and the output shaft of the motor is drivingly connected with the first driving wheels 2211 on both sides of the first slot 101, so that the first wheel set 221 can be controlled to run synchronously.

[0049] Referring to the accompanying drawings Figure 6 - the accompanying drawings Figure 11 The feeding mechanism 4 comprises a second wheel belt 41 and a second power part 42. The second wheel belt 41 is provided with two roots which are symmetrically arranged on both sides of the second slot 102, and a second clamping groove 40 corresponding to the second slot 102 is formed between the two roots of the second wheel belt 41 to orderly arrange the stems of the tobacco leaves. The second power part 42 is installed on the support 10 and is drivingly connected with the two roots of the second wheel belt 41.

[0050] Further, the second power part 42 comprises a second wheel set 421 and a second driving member 422. The second wheel set 421 is provided with two sets and is respectively installed on both sides of the second slot 102. The second wheel set 421 comprises a second driving wheel 4211 and a second auxiliary wheel 4212. The second driving wheel 4211 is provided with at least two roots which are rotatably installed at both ends of one side of the second slot 102. The second auxiliary wheel 4212 is provided with a plurality of roots which are rotatably installed on one side of the second slot 102. The second wheel belt 41 is wound on the two second driving wheels 4211 and the plurality of second auxiliary wheels 4212. The second driving member 422 is installed on the support 10 and is drivingly connected with the second driving wheels 4211 of the two sets of second wheel sets 421 to synchronously drive the two roots of the second wheel belt 41.

[0051] Based on the above, it can be known that the feeding mechanism 4 is used for feeding the tobacco leaves to the throwing and separating mechanism 5 to assist the throwing and separating mechanism 5 to complete the rapid separating operation of the single tobacco leaf. Since the operation principle of the feeding mechanism 4 is the same as that of the feeding mechanism 2, the specific content description of the feeding mechanism 2 in the embodiment can be referred to, and the present application will not be described in detail.

[0052] Referring to the accompanying drawings Figure 2 and the accompanying drawings Figure 11 The feeding mechanism 4 further comprises a guide rod 43 which is installed on the support 10 and is internally provided with a guide groove 430 extending along the length direction of the second slot 102. The picking teeth 310 can enter and exit the guide groove 430 along with the rotation of the picking wheel 31.

[0053] Specifically, when the feeding mechanism 2 feeds the tobacco leaves to the separating mechanism 3, the picking teeth 310 on the picking wheel 31 drive the tobacco stems and extrude part of the tobacco stems into the guide groove 430, so as to increase the force point of the tobacco leaves and reduce the possibility of the tobacco leaves falling during the operation of the feeding mechanism 4.

[0054] Referring to the accompanying drawings Figure 1 - the accompanying drawingsFigure 6 The conveying mechanism 7 is installed on the machine body 1 and located directly below the end of the third slot 103.

[0055] Specifically, when the single tobacco leaf is thrown out by the throwing mechanism 5, it will fall onto the conveying mechanism 7, which can carry and transfer the tobacco leaf to the next process, facilitating subsequent screening and processing of qualified tobacco leaves.

[0056] Referring to the accompanying drawings Figure 1 and the accompanying drawings Figure 6 , considering that the single tobacco leaf may deviate in position when falling from the throwing mechanism 5, causing the conveying mechanism 7 to fail to accurately receive, to solve this problem, the conveying mechanism 7 in the application includes a conveying belt body 71 and a position adjusting assembly 72, the conveying belt body 71 is swingably installed on the machine body 1; the position adjusting assembly 72 includes a support rod 721 and a rotating rod 722, the support rod 721 is obliquely installed on the machine body 1 from bottom to top, and a plurality of fixing holes 7210 are arranged on the upper part of the support rod 721, the plurality of fixing holes 7210 are arranged in an array along the length direction of the support rod 721; one end of the rotating rod 722 is rotatably connected with the conveying belt body 71, and the other end of the rotating rod 722 is fixedly connected with any one of the fixing holes 7210, so as to adjust the inclination of the conveying belt body 71.

[0057] Specifically, in use, the user can swing the conveying belt body 71 according to the actual running track of the tobacco leaf when falling, and after adjusting the inclination of the conveying belt body 71 to a suitable state, the rotating rod 722 is fixedly connected with the corresponding fixing hole 7210; wherein the conveying belt body 71 belongs to the prior art, and therefore this embodiment will not be further described.

[0059] Specifically, the design of the limiting rod 8 can provide support for the tobacco leaf, avoiding shaking of the tobacco leaf during passing through the first slot 101, the second slot 102 and the third slot 103, and reducing the possibility of falling of the tobacco leaf during movement.

[0060] Further, the limiting rod 8 is designed to be inclined relative to the moving track of the tobacco leaf, and the end point of the limiting rod 8 is designed to correspond to the middle part of the conveying mechanism 7, so that the tobacco leaf can be evenly laid on the conveying mechanism 7 after leaving the third slot 103.

[0061] In addition, the limiting rods 8 can be provided in plurality and uniformly abut the tobacco body, so that the tobacco leaf movement is more stable.

[0062] It should also be noted that although the embodiments of the present application have been shown and described, those skilled in the art can understand that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the present application.
