[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0019] See also Figures 1 to 5In an embodiment of the present invention, a tobacco shred screening and loosening device includes a vibration separation component 1, a vibration motor 2, a step vibration groove 3, a shock absorbing assembly 4, a bracket A5 and a bracket B6, both sides of the step vibration groove 3 are connected to the top of the bracket A5 through the shock absorbing assembly 4, the vibration separation component 1 is located above the step vibration groove 3 and is arranged close to one end of the step vibration groove 3, and brackets B6 are arranged on both sides of the vibration separation component 1, one end of the bracket B6 is fixedly connected to the bracket A5, and the other end of the bracket B5 is connected to the side of the vibration separation component 1 through another shock absorbing assembly 4.
[0020] The shock absorbing component can be a spring or a rubber block. The shock absorbing component is used to reduce the vibration transmitted to the bracket.
[0021] The vibration separation component 1 includes a vibration separation rake nail group 11, a vibration separation shell 12 and a connecting angle 13. The vibration separation shell 12 is a square cylindrical shell with inlets and outlets opened at the top and bottom. The vibration separation rake nail group 11 is arranged inside the vibration separation shell 12. The outer surface of the vibration separation shell 12 is fixedly connected with multiple connecting angles 13. The connecting angle 13 is used to connect one end of the shock absorbing component 4. The outer surface of the vibration separation shell 12 is also fixedly connected with a vibration motor 2. The output end of the vibration motor 2 contacts the outer surface of the vibration separation shell 12, so as to vibrate the entire vibration separation shell 12 and the internal vibration separation rake nail group 11 to loosen the tobacco shreds.
[0022] The vibration separation rake nail group 11 includes a mounting plate 111 and a vibration separation rake nail 112. One side of the mounting plate 111 is fixedly connected to one end of a plurality of vibration separation rake nails 112. The plurality of vibration separation rake nails 112 are equidistantly distributed and horizontally arranged in the middle of the vibration separation shell 12. The tobacco shreds are fed in from the upper end of the vibration separation shell 12, are vibrated and separated on the vibration separation rake nails 112, and fall from the lower end opening of the vibration separation shell 12 onto the stepped vibration groove 3.
[0023] The step vibration trough 3 includes a cantilever rake nail group 31 and a vibration trough body 32. The other end of the vibration trough body 32 is opened as a discharge port. Multiple groups of cantilever rake nail groups 31 are arranged in the vibration trough body 32. The multiple groups of cantilever rake nail groups 31 are gradually reduced from the feeding position to the discharge port position. One end of the cantilever rake nail group 31 (feeding position) located below the discharge of the vibration separation component 1 is fixed on both sides of the vibration trough body 32, and the other end of one end of the cantilever rake nail group 31 (feeding position) located below the discharge of the vibration separation component 1 is located above another adjacent cantilever rake nail group 31. And so on, the distribution is gradually reduced, and the screening of tobacco shreds is achieved, that is, the debris is screened, and the qualified tobacco is shaken out from the discharge port. The surface of the vibration trough body 32 of the step vibration trough 3 is also fixedly connected to another vibration motor 2, and the output end of the vibration motor 2 is in contact with the outer surface of the vibration trough body 32.
[0024] The cantilever rake nail group 31 includes an installation cantilever rake nail 311, a cross beam 312 and a connecting flange 313. The two ends of the cross beam 312 are fixedly connected to the connecting flange 313. The connecting flange 313 is fixedly connected to the inner two side walls of the vibration groove body 32 by bolts. A plurality of coplanar installation cantilever rake nails 311 are welded on the surface of the cross beam 312, and the plurality of installation cantilever rake nails 311 are equidistantly distributed.
[0025] Another connecting angle 13 is also welded to the outer surface of the vibration groove body 32 , and the connecting angle 13 is used to connect one end of the shock absorbing component 4 .
[0026] The feeding equipment conveys the tobacco to the vibration separation component 1. While the tobacco moves downward under the action of its own gravity and vibration force, some short tobacco is separated from the tobacco mass under the action of vibration force and falls in the gap of the vibration separation rake nail group 11. The unloosened tobacco mass continues to move downward to the end of the vibration separation rake nail 112 under the action of gravity. Due to the special structural design of the vibration separation rake nail group 11, the amplitude of the vibration separation rake nail 112 gradually increases as it moves away from the mounting plate 111 in the length direction. That is, the loosening strength of the tobacco gradually increases during the sliding process along the vibration separation rake nail 112 until the large tobacco mass is loosened by vibration and falls, and the tobacco falls into the stepped vibration groove 3 below, loosening the small tobacco mass and screening it into free tobacco, providing favorable conditions for the separation of the tobacco from sundries such as stems and stem blocks.
[0027] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
