[0032] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0033] like Figures 1 to 3 As shown, an embodiment of the utility model provides a tobacco raw material foreign matter screening device, including: a base 1, a barrel box 2, a dust exhaust component 3, a vibration separation component 4, a negative pressure purification component 5 and a driving component 6.

In addition, there is a certain distance between the bottom of the barrel box 2 and the base 1.

[0035] The dust exhaust assembly 3 is arranged in the barrel box 2, and the dust exhaust assembly 3 is used to collect foreign matter in the tobacco raw material. Specifically, when the vibration separation assembly 4 drives the tobacco raw material to shake, the gap between the tobacco raw materials is increased, and then the foreign matter in the tobacco raw material is separated from the tobacco raw material, so that the foreign matter falls into the dust exhaust assembly 3.

[0036] The vibration separation assembly 4 includes a collection plate 41, a vibrator 42 and a screen frame 43. The collection plate 41 is rotatably arranged in the barrel box 2, the screen frame 43 is arranged on the end surface of the collection plate 41, and the vibrator 42 is fixed on the collection plate 41 and connected to the screen frame 43. Specifically, the first end of the collection plate 41 takes the central axis of the barrel box 2 as the axis and rotates around the central axis of the barrel box 2 in the barrel box 2, and the screen frame 43 contacts the tobacco raw material, thereby driving the tobacco raw material to shake.

[0037] The negative pressure purification component 5 is arranged at the first end of the barrel box 2 and is used to suck out foreign matter in the dust exhaust component 3.

[0038] The driving assembly 6 is connected to the negative pressure purification assembly 5 and the collecting plate 41 respectively. It should be noted that the driving assembly 6 drives the negative pressure purification assembly 5 and the collecting plate 41 to work respectively, so that the collecting plate 41 rotates around the central axis of the barrel box 2 in the barrel box 2, and the negative pressure purification assembly 5 works to absorb foreign matter in the dust exhaust assembly 3.

[0039] During operation, the driving component 6 starts to control the collection plate 41 and the negative pressure purification component 5 to work, the collection plate 41 rotates in the barrel box 2, and the vibrator 42 drives the screen frame 43 to vibrate, thereby driving the tobacco raw materials to shake. During the dynamic movement of the tobacco raw materials, the gaps between the tobacco raw materials are increased, and foreign matter in the tobacco raw materials falls into the dust exhaust component 3, thereby removing debris in the tobacco raw materials.

[0040] The utility model is provided with a dust discharge assembly 3 in the barrel box 2, a collection plate 41 rotatably provided in the barrel box 2, a screen frame 43 provided on the end surface of the collection plate 41, a vibrator 42 fixed on the collection plate 41 and connected with the screen frame 43; and a negative pressure purification assembly 5 is provided at the first end of the barrel box 2, so that a driving assembly 6 is connected with the negative pressure purification assembly 5 and the collection plate 41 respectively. When working, the driving assembly 6 starts to control the collection plate 41 and the negative pressure purification assembly 5 to work, the collection plate 41 rotates in the barrel box 2, the vibrator 42 drives the screen frame 43 to vibrate, and then drives the tobacco raw material to shake, and in the process of dynamic movement of the tobacco raw material, the gap between the tobacco raw materials is increased, and then the foreign matter in the tobacco raw material falls into the dust discharge assembly 3, thereby removing the sundries in the tobacco raw material, improving the separation effect of the tobacco raw material and the foreign matter, and improving the quality of screening the foreign matter of the tobacco raw material.

[0041] In one embodiment of the tobacco raw material foreign matter screening device of the utility model, as Figure 3 As shown, the vibration separation assembly 4 also includes a flexible brush 44 , the driving assembly 6 is connected to the first end of the collecting plate 41 , the flexible brush 44 is arranged at the second end of the collecting plate 41 , and the flexible brush 44 abuts against the inner wall of the barrel box 2 .

[0042] The utility model connects the driving assembly 6 to the first end of the collecting plate 41, and the flexible brush 44 is arranged at the second end of the collecting plate 41, and the flexible brush 44 abuts against the inner wall of the barrel box 2. The flexible brush 44 reduces the friction between the inner wall of the collecting plate 41 and the barrel box 2, and also prevents the tobacco raw materials from falling from the collecting plate 41 and the barrel box 2, thereby further improving the screening quality of foreign matter in the tobacco raw materials.

[0043] In one embodiment of the tobacco raw material foreign matter screening device of the present invention, the length of the collecting plate 41 is slightly smaller than the diameter of the barrel box 2, and the width of the collecting plate 41 is equal to the depth of the barrel box 2. This arrangement allows the collecting plate 41 to rotate smoothly in the barrel box 2.

[0044] In one embodiment of the tobacco raw material foreign matter screening device of the utility model, as Figure 1 to Figure 2 As shown, a feed cylinder 21 is provided on the top of the barrel box 2 , and the feed cylinder 21 is connected to the barrel box 2 for introducing tobacco raw materials into the barrel box 2 .

[0045] Specifically, an electromagnetic valve is provided on the inner side of the top of the feed barrel 21, and the feed barrel 21 can be connected to the feeding device on the top (not shown in the figure). When feeding, the electromagnetic valve inside the feed barrel 21 opens, and the tobacco raw material is introduced into the barrel box 2 through the feed barrel 21.

[0046] The utility model provides a feed cylinder 21 on the top of the barrel box 2, the feed cylinder 21 is connected with the barrel box 2, and tobacco raw materials are brought into the barrel box 2 through the feed cylinder 21, thereby ensuring the normal operation of the equipment.

[0047] In one embodiment of the tobacco raw material foreign matter screening device of the utility model, as Figure 1 to Figure 2 As shown, the dust exhaust assembly 3 includes a first dust exhaust net slot 31 and a second dust exhaust net slot 32 . The first dust exhaust net slot 31 is arranged parallel to the base 1 and is in the same plane as the central axis of the barrel box 2 . The second dust exhaust net slot 32 is located at the bottom of the barrel box 2 .

[0048] like Figure 1 As shown, when the collecting plate 41 drives the tobacco raw material to rotate 90 degrees, at this time, the collecting plate 41 moves to the position of the first dust removal mesh slot 31, and the vibrator 42 runs regularly for a certain period of time, driving the tobacco raw material and the screen frame 43 to vibrate, thereby increasing the separation gap between the tobacco raw materials, separating foreign matter and dust from the tobacco raw materials, and some of the separated foreign matter and dust are collected by the first dust removal mesh slot 31, and another part of the foreign matter and dust with larger mass falls to the bottom side of the barrel box 2 and is collected by the second dust removal mesh slot 32.

[0049] Moreover, when the collecting plate 41 drives the tobacco raw material to rotate at an angle greater than 90 degrees, under the action of gravity, the tobacco raw material slides off the collecting plate 41 and falls to the bottom side of the barrel box 2. During the falling process, foreign matter and dust are also separated from the tobacco raw material. When the collecting plate 41 rotates to the bottom of the barrel box 2 again, the above operation is repeated, and the tobacco raw material is dynamically driven multiple times, thereby effectively separating the tobacco raw material from foreign matter.

[0050] In one embodiment of the tobacco raw material foreign matter screening device of the utility model, as Figure 1 to Figure 2 As shown, the bottom of the barrel box 2 has a discharge port, and a blocking base frame 22 is provided on the outer wall of the barrel box 2. The blocking base frame 22 is slidably connected to the outer wall of the barrel box 2, and the blocking base frame 22 is used to close or open the discharge port.

[0051] The blocking base frame 22 can close and block the bottom groove on the bottom side of the barrel box 2, and in this position, the arc-shaped inner side of the blocking base frame 22 away from the connecting shaft frame 62 is on the same curved surface as the inner wall of the barrel box 2, so that the inner wall of the barrel box 2 forms a complete circumference.

[0052] Specifically, the driving assembly 6 is connected to the blocking chassis 22. When the tobacco raw material needs to be cleaned, the driving assembly 6 drives the blocking chassis 22 to move, so that the blocking chassis 22 blocks the discharge port, and then the driving assembly 6 drives the collecting plate 41 to rotate, so that the collecting plate 41 removes impurities from the tobacco raw material. After the tobacco raw material is cleaned, the driving assembly 6 drives the blocking chassis 22 to move out of the discharge port, so that the tobacco raw material can be discharged from the discharge port.

[0053] The utility model sets a discharge port at the bottom of the barrel box 2, so that the blocking base frame 22 is slidably connected with the outer wall of the barrel box 2, thereby opening and closing the discharge port, thereby cooperating with the barrel box 2 to remove impurities from the tobacco raw materials.

[0054] In one embodiment of the tobacco raw material foreign matter screening device of the utility model, as Figure 1 to Figure 2 As shown, the driving assembly 6 includes a first driving member 61 and a connecting shaft frame 62. The first driving member 61 is arranged on the outer wall of the barrel box 2, and the output shaft of the first driving member 61 is connected to the first end of the connecting shaft frame 62, and the second end of the connecting shaft frame 62 is connected to the blocking base frame 22 to drive the blocking base frame 22 to move along the axial direction of the barrel box 2.

[0055] The utility model arranges the first driving member 61 on the outer side wall of the barrel box 2, and the output shaft of the first driving member 61 is connected to the first end of the connecting shaft frame 62, and the second end of the connecting shaft frame 62 is connected to the blocking base frame 22. The first driving member 61 drives the connecting shaft frame 62 to move, and the movement of the connecting shaft frame 62 drives the blocking base frame 22 to move along the axial direction of the barrel box 2, so that the blocking base frame 22 controls the opening and closing of the discharge port, thereby improving the automation of the utility model and reducing the labor intensity of the operator.

[0056] In addition, the blocking chassis 22 can also be tilted on one side of the blocking chassis 22 after the foreign matter and dust are screened out, so as to discharge the tobacco raw materials. Specifically, when the foreign matter and dust are screened out, the first driving members 61 on both sides move synchronously, driving the blocking chassis 22 to move down a certain distance longitudinally, and then the first driving member 61 on one side continues to move down a certain distance, so that the blocking chassis 22 rotates and tilts to one side, thereby realizing the directional conveying of the tobacco raw materials on the blocking chassis 22.

[0057] Furthermore, the first driving member 61 is not limited to an electric telescopic rod, and may also be driven by a linear motor, an electric cylinder, or a pneumatic cylinder, etc., as long as the movement and adjustment of the blocking base frame 22 can be achieved, and no specific limitation is made here.

[0058] In one embodiment of the tobacco raw material foreign matter screening device of the utility model, as Figure 1 to Figure 2As shown, a mounting hole 23 is provided on the first end of the barrel box 2; the negative pressure purification component 5 includes a filter wind bin 51, a negative pressure blade 52, a first connecting bin 53 and a second connecting bin 54, the filter wind bin 51 is arranged in the mounting hole 23, the negative pressure blade 52 is arranged in the filter wind bin 51, and is connected to the driving component 6, the first end of the first connecting bin 53 and the first end of the second connecting bin 54 are respectively connected to the first dust exhaust net slot 31 and the second dust exhaust net slot 32, the second end of the first connecting bin 53 and the second end of the second connecting bin 54 are connected to the mounting hole 23, and are used to suck out foreign matter in the first dust exhaust net slot 31 and the second dust exhaust net slot 32.

[0059] Specifically, a filter element (not shown in the figure) is arranged inside the first connecting chamber 53 and the second connecting chamber 54. When working, the driving assembly 6 controls the collection plate 41 and the negative pressure blade 52 to rotate at the same time. Due to the rapid rotation of the negative pressure blade 52, negative pressure is formed inside the filter air chamber 51, the first connecting chamber 53 and the second connecting chamber 54. At the same time, negative pressure is also formed inside the first dust discharge net slot 31 and the second dust discharge net slot 32 connected to the first connecting chamber 53 and the second connecting chamber 54. The foreign matter and dust sucked by the negative pressure of the first dust discharge net slot 31 and the second dust discharge net slot 32 are filtered by the filter element, and the foreign matter is sucked into the filter air chamber 51 and discharged.

[0060] The utility model arranges the filter wind bin 51 in the mounting hole 23, the negative pressure blade 52 is arranged in the filter wind bin 51 and is connected to the drive assembly 6, the first end of the first connecting bin 53 and the first end of the second connecting bin 54 are respectively connected to the first dust exhausting net slot 31 and the second dust exhausting net slot 32, the second end of the first connecting bin 53 and the second end of the second connecting bin 54 are connected to the mounting hole 23, thereby ensuring that foreign matter in the tobacco raw material can be discharged from the barrel box 2, and further improving the quality of screening out foreign matter in the tobacco raw material.

[0061] In one embodiment of the tobacco raw material foreign matter screening device of the utility model, as Figure 1 to Figure 2 As shown, the driving assembly 6 further includes a second driving member 63 and a reducer 64 . The output shaft of the second driving member 6 is connected to the negative pressure blade 52 and the reducer 64 respectively, and the reducer is connected to the collecting plate 41 .

[0062] Specifically, a shaft is installed on the first end of the collecting plate 41 , and the shaft is connected to the reducer 64 . When the tobacco raw material is introduced into the barrel box 2 , it is located at the second end of the collecting plate 41 .

[0063] When the second driving member 63 is running, in cooperation with the reducer 64, it can drive the vibration separation component 4 to rotate axially at a slow speed. The second driving member 63 is not limited to an electric roller shaft, and can also be driven by a linear motor, an electric cylinder or a cylinder, etc., as long as the synchronous rotation drive of the negative pressure blade 52 and the vibration separation component 4 can be achieved, and no specific limitation is made here.

[0064] The utility model connects the output shaft of the second driving member 6 to the negative pressure blade 52 and the reducer 64 respectively, and the reducer is connected to the collecting plate 41, so that the collecting plate 41 is caused to rotate axially at a slow speed through the reducer 64, thereby avoiding the problem of poor debris separation effect caused by excessive rotation of the collecting plate 41.

[0065] The working process of the tobacco raw material foreign body screening device of the utility model is as follows: when feeding, the electromagnetic valve inside the feed barrel 21 is opened, and the tobacco raw material is introduced into the barrel box 2 through the feed barrel 21. The first driving member 61 works to drive the blocking chassis 22 to block the discharge port.

[0066] Next, the second driving member 63 works, and the second driving member 63 controls the collection plate 41 and the negative pressure blade 52 to rotate at the same time, so that the reducer 64 decelerates the collection plate 41, and the collection plate 41 rotates slowly in the barrel box 2, and the vibrator 42 drives the screen frame 43 to vibrate, thereby driving the tobacco raw material to shake, and in the process of dynamic movement of the tobacco raw material, the gap between the tobacco raw materials is increased. When the collection plate 41 drives the tobacco raw material to rotate 90 degrees, at this time, the collection plate 41 moves to the position of the first dust removal mesh slot 31, and the vibrator 42 runs regularly for a certain period of time, driving the tobacco raw material and the screen frame 43 to vibrate, thereby increasing the separation gap between the tobacco raw materials, separating foreign matter and dust from the tobacco raw material, and the separated foreign matter and dust are collected by the first dust removal mesh slot 31, and the other part of the foreign matter and dust with larger mass falls to the bottom side of the barrel box 2 and is collected by the second dust removal mesh slot 32.

[0067] Moreover, when the collecting plate 41 drives the tobacco raw material to rotate at an angle greater than 90 degrees, under the action of gravity, the tobacco raw material slides off the collecting plate 41 and falls to the bottom side of the barrel box 2. During the falling process, foreign matter and dust are also separated from the tobacco raw material. When the collecting plate 41 rotates to the bottom of the barrel box 2 again, the above operation is repeated, and the tobacco raw material is dynamically driven multiple times, thereby effectively separating the tobacco raw material from foreign matter.

[0068] At this time, due to the rapid rotation of the negative pressure blade 52, negative pressure is formed inside the filter wind bin 51, the first connecting bin 53 and the second connecting bin 54. At the same time, negative pressure is also formed inside the first dust exhaust net slot 31 and the second dust exhaust net slot 32 connected to the first connecting bin 53 and the second connecting bin 54. The foreign matter and dust sucked in by the negative pressure of the first dust exhaust net slot 31 and the second dust exhaust net slot 32 are filtered through the filter element, and then the foreign matter is sucked into the filter wind bin 51 and discharged.

[0069] When the screening of foreign matter and dust is completed, the first driving members 61 on both sides move synchronously, driving the blocking base 22 to move downward longitudinally for a certain distance, and then the first driving member 61 on one side continues to move downward for a certain distance, so that the blocking base 22 rotates and tilts to one side, thereby realizing the directional guiding of the tobacco raw materials on the blocking base 22.

It should be understood by those skilled in the art that the above embodiments may be modified without departing from the scope and spirit of the present invention.
