Description

Technical Field

[0001] The utility model relates to the technical field of popping bead screening, in particular to a popping bead screening machine for cigarettes. Background Art

[0002] Popping beads are also called fragrance pills, brittle capsules, and beads. They come in different sizes, with a diameter of 2.6 to 4.6 mm. They are squeezable beads that feel like they are popping when squeezed. They are mainly used in cigarette filters, which are often called popping bead cigarettes. After production, the popping beads may be broken, empty, or too small in size. These need to be removed and quality-compliant popping beads selected.

[0003] Because the particle sizes of popping beads vary, traditional screening structures can easily cause the beads to get stuck in the sieve holes, causing blockage and preventing further screening. Defective products that meet the required size but are empty shells can also affect the screening effect. Therefore, we propose a popping bead sorting machine for tobacco. Utility Model Content

[0004] The purpose of the utility model is to provide a pill-selecting machine for popping beads for cigarettes, which is provided with a first fan for horizontal blowing above the side of the feed hopper and a second fan for obliquely blowing upward toward the inside of the feed hopper. By utilizing the horizontal and oblique upward blowing effects, the empty shells therein can be effectively removed, and the popping beads will be filtered and screened through the filter screen and the filter cartridge after entering the screening cylinder. During screening, the filter screen and the filter cartridge are in a flipped state, which makes it difficult for the popping beads to be stuck in the sieve holes, thereby solving the problems raised in the background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a pill-selecting machine for popping beads for cigarettes, comprising a screening drum and a feed hopper, the feed hopper being arranged above the side of the screening drum, and the bottom of the feed hopper being connected to the interior of the screening drum; a rotating rod is longitudinally rotatably installed inside the screening drum, and a cylindrical filter drum is fixed to the outer ring of the rotating rod through a connecting rod, and a plurality of filter screens are evenly fixed on the outer surface of the filter drum, the bottom of the screening drum is connected to a first discharge port connected to the interior thereof, and a second discharge port connected to the interior thereof is connected to the lower position of the side of the screening drum; a vertical plate is vertically fixed to the upper side of the feed hopper, a first fan is installed on the surface of the vertical plate, the outside of the feed hopper below the vertical plate is obliquely connected to an air inlet duct connected to the interior thereof, and a second fan is installed in the air inlet duct.

[0006] By adopting the above technical solution, when the popping beads enter through the feed hopper, they are blown by the first fan and the second fan to remove empty shell impurities, and then enter the screen cylinder. After being screened by the filter screen and the filter cylinder, large-sized popping beads that meet the requirements and small-sized popping beads that do not meet the requirements are separated.

[0007] Optionally, a stepping motor is installed at the middle position of the front end of the screening drum, and the stepping motor is transmission-connected to the rotating rod.

[0008] By adopting the above technical solution, the stepping motor drives the longitudinal rotating rod to rotate, thereby driving the filter cartridge and the filter screen to rotate.

[0009] Optionally, a through opening is provided on the surface of the vertical plate at the air outlet of the first fan, and the through opening passes through the vertical plate.

[0010] By adopting the above technical solution, the wind blown out by the first fan is blown to the right through the opening.

[0011] Optionally, a baffle is embedded and fixed on the upper part of the interior of the air inlet cylinder, and the baffle is flush with the inner wall of the feed hopper.

[0012] By adopting the above technical solution, the barrier net can prevent the dropped explosive beads from falling into the air inlet tube.

[0013] Optionally, the filter screen and the filter cartridge have the same filter pore diameter, and the edge of the filter screen is close to the inner wall of the screening cartridge.

[0014] By adopting the above technical solution, the filter screen and the filter cartridge can filter the explosive beads of the same size.

[0015] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0016] 1. The technical solution of the present application is to set a first fan for blowing air horizontally above the side of the feed hopper, and a second fan for blowing air obliquely upward inside the feed hopper is set below. By utilizing the horizontal and oblique upward blowing effects, the empty shells therein can be effectively removed, and after the burst beads enter the screening cylinder, they will be filtered and screened by the filter screen and the filter cartridge. During screening, the filter screen and the filter cartridge are in a flipped state, which makes it less likely for the burst beads to be stuck in the sieve holes.

[0017] 2. The technical solution of the present application enables the second fan to blow air upward at an angle, thereby easily blowing away the empty shells that have not been removed completely. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] See also Figure 1-2 The utility model provides a technical solution: a tobacco popping bead selection machine, comprising a screening drum 1 and a feed hopper 2, the feed hopper 2 being arranged above the right side of the screening drum 1, the bottom of the feed hopper 2 being connected with the interior of the screening drum 1, the popping beads to be selected and screened can be fed downward from the feed hopper 2 into the interior of the screening drum 1, and the bottom outer ring of the screening drum 1 is vertically supported by a support leg.

[0023] A vertical plate 21 is fixed vertically on the upper left side of the feed hopper 2, and a first fan 211 is installed on the left surface of the vertical plate 21. A through hole 212 is opened on the surface of the vertical plate 21 at the air outlet on the right side of the first fan 211, and the through hole 212 runs through the vertical plate 21. When the popping beads are put into the feed hopper 2, the first fan 211 is started to blow air to the right through the through hole 212, so as to blow away the empty shells in the popping beads. The outer part of the lower left side of the feed hopper 2 is obliquely connected to an air inlet tube 22 connected with its interior, and a second fan 221 is installed in the air inlet tube 22. The second fan 221 can blow air obliquely into the upper feed hopper 2, and the empty shells that have not been completely blown away are blown away again by tilting them toward the upper right side. A blocking net 222 is embedded and fixed on the upper part of the interior of the air inlet tube 22, and the blocking net 222 is flush with the inner wall of the feed hopper 2 to prevent the popping beads from entering the air inlet tube 22.

[0024] The interior of the screening drum 1 is longitudinally rotatably equipped with a rotating rod 3, and a stepping motor 13 is installed in the middle position of the front end of the screening drum 1. The stepping motor 13 is connected to the rotating rod 3 for transmission, and can drive the rotating rod 3 to rotate counterclockwise. The outer ring of the rotating rod 3 is fixed with a cylindrical filter cartridge 31 through a connecting rod 32. The front and rear ends of the filter cartridge 31 are close to the front and rear end inner walls of the screening drum 1. A plurality of filter screens 311 are evenly fixed on the outer surface of the filter cartridge 31. The filter screens 311 and the filter cartridge 31 have the same filter pore diameter. The edge of the filter screen 311 is close to the inner wall of the screening drum 1. The small and medium-sized beads will pass through the filter screen 311 and the filter cartridge 31 and fall to the bottom of the screening drum. At the bottom of the separation cylinder 1, the bottom of the screening cylinder 1 is connected to a first discharge port 11 that is connected to the interior thereof, so that small-sized or broken popping beads are discharged to the outside from the first discharge port 11. When the filter screen 311 and the filter cartridge 31 rotate, they will drive the popping beads with large size and load requirements to rotate counterclockwise. During rotation, the filter screen 311 and the filter cartridge 31 will also flip over, so that the popping beads stuck in the filter holes of the filter screen 311 or the filter cartridge 31 can fall under the action of gravity and avoid getting stuck. The left side lower position of the screening cylinder 1 is connected to a second discharge port 12 that is connected to the interior thereof, and finally the popping beads that meet the requirements are discharged from the second discharge port 12.

[0025] When in use, the stepper motor 13, the first fan 211 and the second fan 221 are all connected to the control device and powered on, the stepper motor 13 is started to drive the rotating rod 3, the filter cartridge 31 and the filter screen 311 to rotate counterclockwise, and the first fan 211 and the second fan 221 are started at the same time, and the popping beads to be screened by the pills are thrown from the top of the feed hopper 2 to the bottom. First, the first fan 211 blows air to the right to blow the empty shells in the popping beads to the side so that they cannot fall into the feed hopper 2. When the popping beads continue to fall downward, the second fan 221 blows air upward at an angle, which can further blow the empty shells mixed in the popping beads that have not been completely blown away upward and blow them out and separate them, and the remaining popping beads are blown from the bottom The beads fall into the interior of the screening drum 1 and fall into the side of the filter drum 31 between the filter screens 311. The beads that are small in size and do not meet the requirements or are broken can leak to the bottom through the filter screen 311 or fall into the filter drum 31, and then pass through the filter screen 311 at the bottom or the bottom of the filter drum 31 again, and finally are discharged to the outside from the first discharge port 11 at the bottom. The beads that are large in size and meet the requirements are driven by the filter screen 311 to rotate counterclockwise to the left. The filter screen 311 will turn over when it rotates counterclockwise, so that the beads stuck in the mesh will fall under the action of gravity. Finally, when it rotates to the position of the second discharge port 12, the beads that meet the requirements are discharged from the second discharge port 12.
