[0032] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] Combine the following Figures 1 to 5 , through specific embodiments and application scenarios, the discharge cleaning mechanism and the on-site air separator provided by the embodiment of the utility model are described in detail.

[0034] First, as Figure 1 and Figure 2 As shown, the discharging and cleaning mechanism 1 provided by the utility model comprises: a discharging body 11 , a roller 12 , a cleaning assembly 13 and an end cover 14 .

[0035] The discharge body 11 has a discharge cavity 111 and an opening communicating with the discharge cavity 111. An end cover 14 is connected to the wall at the opening, and the end cover 14 is used to cover and seal the discharge cavity 111.

[0036] The bottom of the discharge body 11 is provided with a discharge port 112 communicated with the discharge cavity 111 , and the roller 12 is rotatably disposed in the discharge cavity 111 to guide the tobacco to be discharged from the discharge port 112 .

[0037] The cleaning assembly 13 is disposed between the roller 12 and the end cover 14 . One end of the cleaning assembly 13 is fixed to the end of the roller 12 , and the other end of the cleaning assembly 13 contacts a side surface of the end cover 14 close to the roller 12 .

[0038] The bottom of the end cover 14 near the drum 12 is provided with a flue gas outlet 1421 and a baffle 1422. The baffle 1422 is used to guide the tobacco debris on the end cover 14 to be discharged from the flue gas outlet 1421.

[0039] It is understandable that if Figure 1 As shown, the on-site air separation machine includes an air separation box 2. The discharge cleaning mechanism 1 is arranged at the bottom of the air separation box 2, and is used to discharge the tobacco shreds separated by the air separation box 2. The top of the discharge body 11 is connected to a side of the bottom of the air separation box 2. Optionally, the discharge body 11 and the air separation box 2 are formed as one body by injection molding process to simplify the assembly steps. The bottom of the discharge body 11 is provided with a discharge port 112 connected to the outside. The discharge port 112 is used to discharge the separated tobacco shreds.

[0040] The discharge body 11 is provided with a discharge cavity 111. The cavity of the air separation box 2 is connected with the discharge cavity 111, and the separated tobacco enters the discharge cavity 111 through the air separation box 2. The discharge cavity 111 is connected with the discharge port 112. It can be understood that when the on-site air separation machine works normally, a relatively sealed negative pressure environment needs to be maintained in the air separation box 2. The roller 12 is accommodated in the discharge cavity 111 and can rotate relative to the wall of the discharge cavity 111. On the one hand, during the rotation of the roller 12, it can guide the tobacco in the discharge cavity 111 to be discharged from the discharge port 112; on the other hand, the roller 12 is sandwiched between the air separation box 2 and the discharge port 112, which can prevent outdoor gas from entering the air separation box 2 from the discharge port 112, thereby ensuring the air tightness of the air separation box 2, thereby ensuring the separation effect of the air separation box 2 on the tobacco.

[0041] For the convenience of inspection and cleaning, two opposite sides of the discharge body 11 are provided with openings communicating with the outside world. The openings are also communicated with the discharge cavity 111. There are two end caps 14. After inspection and cleaning, the two end caps 14 are respectively sealed to the openings on the opposite sides of the discharge body 11.

[0042] Optionally, the end cover 14 can be fixed to the wall at the opening by bolts. Alternatively, the end cover 14 can be locked to the wall at the first opening by a clamp.

[0043] The two opposite end surfaces of the roller 12 are respectively located at the openings at the two ends of the discharge body 11. Figure 2 As shown, in order to ensure that the drum 12 has a rotatable space, there is a large gap between the end cover 14 and the end surface of the drum 12.

[0044] like Figure 2 As shown, the end cap 14 is groove-shaped. During the production process, some tobacco debris is still mixed in the tobacco shreds separated by the air separation box 2. When the separated tobacco shreds pass through the roller 12, some of the tobacco debris mixed in them passes through the gap between the end cap 14 and the end surface of the roller 12, falls on the end cap 14, and cannot be discharged.

[0045] The cleaning assembly 13 is located between the end cover 14 and the end surface of the drum 12. One end of the cleaning assembly 13 is fixed to the end surface of the drum 12; the other end of the cleaning assembly 13 is in contact with the end cover 14. The cleaning assembly 13 can rotate with the drum 12, so as to clean the tobacco debris falling on the end cover 14.

[0046] like Figure 2 As shown, the baffle 1422 is fixed to the bottom of the end cover 14. The baffle 1422 can guide the tobacco debris swept by the cleaning assembly 13 to be discharged from the outlet 1421.

[0047] The utility model provides a discharging cleaning mechanism 1, wherein the discharging body 11 has a discharging cavity 111, and the bottom of the discharging body 11 has a discharging port 112 connected with the discharging cavity 111, and the separated tobacco shreds are discharged from the discharging port 112 through the discharging cavity 111; the discharging body 11 is provided with an opening connected with the discharging cavity 111, which is convenient for maintenance and cleaning; the end cover 14 is connected with the wall at the opening, and the discharging cavity 111 is sealed by the end cover 14 to maintain a relatively stable sealing environment in the on-site air separator; the drum 12 can rotate It is arranged in the discharge cavity 111 to guide the tobacco to be discharged from the discharge port 112; at the same time, one end of the cleaning component 13 is fixed to the end of the drum 12, and the other end of the cleaning component 13 contacts the side of the end cover 14 close to the drum 12, and the cleaning component 13 rotates with the drum 12 to clean the tobacco debris on the end cover 14; the bottom of the end cover 14 close to the side of the drum 12 is provided with a discharge port 1421 and a baffle 1422, and the baffle 1421 can guide the tobacco debris cleaned by the cleaning component 13 to be discharged from the discharge port 1422.

[0048] Specifically, Figure 2 and Figure 3 As shown, the end cover 14 includes an end cover body 141 and a peripheral wall 142 . The peripheral wall 142 is disposed at the outer edge of the end cover body 141 and extends along the circumference of the end cover body 141 .

[0049] The debris outlet 1421 and the baffle 1422 are both disposed on the peripheral wall 142 and arranged in parallel along the extension direction of the peripheral wall 142. The baffle 1422 is located at one end of the peripheral wall 142 close to the drum 12, and the debris outlet 1421 is located at one end of the baffle 1422 away from the drum 12.

[0050] It is understandable that the end cover body 141 is connected to the surrounding wall 142. Optionally, the end cover body 141 and the surrounding wall 142 are an integrally connected structure. The baffle 1422 is provided on the surrounding wall 142, and the baffle 1422 is located in the bottom area of ​​the end cover body 141. Specifically, the debris outlet 1421 and the baffle 1422 are spaced apart along the extension direction of the surrounding wall 142. Among them, the debris outlet 1421 is located between the end cover body 141 and the baffle 1422. Thus, a groove is formed between the end cover body 141, the surrounding wall 142 and the baffle 1422. The debris outlet 1421 is located at the bottom of the groove. The tobacco debris swept by the cleaning component 13 falls into the groove due to gravity and is discharged to the outside along the debris outlet 1421.

[0051] The baffle 1422 is located at one end of the peripheral wall 142 close to the drum 12 to block a portion of the gap between the end surface of the drum 12 and the end cover 14, thereby preventing tobacco debris from passing through the gap and being discharged from the discharge port 112 together with the tobacco that subsequently enters the discharge cavity 111, thereby ensuring the quality of the tobacco.

[0052] In some embodiments, the cleaning assembly 13 includes a bracket 131 and a cleaning member 132. The bracket 131 is fixed to the end surface of the drum 12. One end of the cleaning member 132 is mounted on the bracket 131, and the other end of the cleaning member 132 contacts a side surface of the end cover 14 close to the drum 12.

[0053] It is understandable that the cleaning member 132 is used to clean tobacco debris on the end cover 14; the bracket 131 is used to provide support for the cleaning member 132 to be fixed to the end surface of the drum 12. Figure 4 As shown, the bracket 131 is L-shaped. The bracket 131 has a straight portion and a bent portion. The straight portion is used to connect with the drum 12; the bent portion is used to provide support for the cleaning member 132. The straight portion fits the end surface of the drum 12, and the bracket 131 is locked on the end surface of the drum 12 by means of a fastener; one end of the cleaning member 132 is fixed to the bent portion by another fastener, and the other end of the cleaning member 132 contacts a side of the end cover 14 close to the drum 12. Optionally, the fastener is a screw.

[0054] In other embodiments, the cleaning assembly 13 includes an adhesive and a cleaning member 132. One side of the adhesive is fixedly connected to the roller 12, and the other side of the adhesive is fixedly connected to one end of the cleaning member 132. The end of the cleaning member 132 facing away from the adhesive contacts the side of the end cap 14 close to the roller 12.

[0055] It is understandable that the adhesive member has good adhesive properties and can firmly fix the cleaning member 132 to the end of the roller 12. Optionally, the adhesive member is a glue stick. Optionally, the adhesive member is a double-sided adhesive.

[0056] In some embodiments, cleaning member 132 is annular.

[0057] It is understandable that the cleaning member 132 is a circular ring-shaped cleaning member. The circular ring-shaped cleaning member is relatively large in size to increase the contact area between it and the end cover 14, thereby enhancing the cleaning force on the end cover 14. The center of the circular ring-shaped cleaning member coincides with the center of the end cover 14.

[0058] Specifically, the two ends of the annular cleaning member have a first radial surface and a second radial surface, respectively. The first radial surface can be fixed to the end of the drum 12 by means of an adhesive or a bracket 131; the second radial surface of the annular cleaning member contacts a side of the end cover 14 close to the drum 12; and the annular cleaning member can clean tobacco debris on the side of the end cover 14 close to the drum 12 during the rotation of the drum 12.

[0059] Optionally, the number of the annular cleaning member is one. When the annular cleaning member rotates to the area near the baffle 1422, the distance between the circumferential wall of the large circumference of the annular cleaning member and the baffle 1422 is small. The distance between the circumferential wall of the large circumference of the annular cleaning member and the baffle 1422 is sufficient as long as it can ensure that the annular cleaning member avoids the baffle 1422 during the rotation process. In addition, the radial dimension of the annular cleaning member can be set as large as possible to increase the cleaning area of ​​the end cover 14 by the annular cleaning member.

[0060] Alternatively, the cleaning member 132 is directly configured as a circular cleaning member. On the premise that the circular cleaning member can avoid the baffle 1422 during the rotation process, the size of the circular cleaning member can be configured as large as possible to increase the cleaning area of ​​the end cover 14 by the circular cleaning member.

[0061] In other embodiments, Figure 4 As shown, the cleaning member 132 is a strip-shaped protrusion, and a plurality of strip-shaped protrusions are arranged at intervals along the circumference of the end surface of the drum 12 .

[0062] It is understandable that the plurality of strip-shaped protrusions are arranged at intervals along the same circumference on the end surface of the drum 12. Correspondingly, there are a plurality of brackets 131. The plurality of strip-shaped protrusions are connected to the plurality of brackets 131 in a one-to-one correspondence. Optionally, the number of the strip-shaped protrusions is four.

[0063] Specifically, one end of the strip-shaped protrusion is mounted on the bracket 131 by a screw or other fixing member; the other end of the strip-shaped protrusion contacts a side of the end cover 14 close to the drum 12. During the rotation of the drum 12, the multiple strip-shaped protrusions clean the tobacco debris on the end cover 14 at the same time.

[0064] In some other embodiments, the strip-shaped protrusions are provided in multiple layers, the multiple layers of strip-shaped protrusions are arranged at intervals along the radial direction of the drum 12, and the strip-shaped protrusions in the same layer are arranged at intervals along the circumference of the drum 12. The adhesive has multiple layers, and the multiple layers of adhesive are arranged at intervals along the radial direction of the drum 12. The multiple layers of strip-shaped protrusions are connected to the multiple layers of adhesive in a one-to-one correspondence; the multiple strip-shaped protrusions in the same layer are connected to the multiple adhesives in the same layer in a one-to-one correspondence.

[0065] The number of strip-shaped protrusions in each layer may be the same or different. Optionally, the strip-shaped protrusions are provided in two layers, and the number of strip-shaped protrusions in each layer is three.

[0066] Of course, the cleaning member 132 may also be an arc-shaped protrusion. The present invention does not specifically limit the specific structure of the cleaning member 132, nor does it limit the corresponding relationship between the structure of the cleaning member 132 and the way it is fixed to the drum 12. The user can select a suitable cleaning member 132 and the way it is fixed to the drum 12 according to actual needs. In addition, the present invention does not specifically limit the number of cleaning members 132, and the user can reasonably increase or decrease the number of cleaning members 132 according to the specifications of the drum 12 and the end cover 14.

[0067] Specifically, in some embodiments, the cleaning member 132 is a flexible member, and a wavy stripe is provided on one end surface of the flexible member close to the end cover 14 .

[0068] It is understandable that the material of the cleaning member 132 is a light and flexible material. The flexible member has a certain strength and wear resistance to ensure the cleaning strength of the end cover 14. In addition, the flexible member will not scratch the end cover 14, and will not affect the normal use of the end cover 14.

[0069] Optionally, the flexible member is a rubber member.

[0070] Optionally, the flexible member is a sponge sheet.

[0071] Furthermore, a wave-shaped stripe is provided on one end surface of the flexible member close to the end cover 14 to increase the friction between the flexible member and the end cover 14 , thereby increasing the cleaning force of the flexible member on the end cover 14 .

[0072] Furthermore, the drum 12 includes a first end plate 121, blades 122 and a second end plate 123. There are a plurality of blades 122, which are disposed between the first end plate 121 and the second end plate 123 and arranged at intervals along the circumference of the first end plate 121.

[0073] It is understandable that the drum 12 further includes a connecting rod. The blade 122 is plate-shaped. There are a plurality of blades 122. Optionally, as Figure 5 As shown, there are six blades 122. The plurality of blades 122 are all fixedly connected to the outer wall of the connecting rod, and the plurality of blades 122 are arranged at intervals along the circumference of the connecting rod.

[0074] The first end plate 121 and the second end plate 123 are circular. The first end plate 121 and the second end plate 123 are respectively located at the two ends of the drum 12. One end of the connecting rod is fixed to the first end plate 121; the other end of the connecting rod is fixed to the second end plate 123. The line connecting the center of the first end plate 121 and the center of the second end plate 123 coincides with the axis of the connecting rod to ensure the balance of the drum 12.

[0075] The two ends of the blade 122 are fixedly connected to the first end plate 121 and the second end plate 123 respectively to ensure the integrity of the drum 12. Figure 5 As shown, the plurality of blades 122 are radially arranged along the circumference of the first end plate 121 .

[0076] Preferably, the first end plate 121, the second end plate 123, the plurality of blades 122 and the connecting rod can be formed into one piece by an injection molding process so as to simplify the assembly steps.

[0077] Furthermore, the discharge cleaning mechanism 1 also includes a driving assembly 15 , which is connected to the drum 12 , and is used to drive the drum 12 to rotate.

[0078] It is understandable that if Figure 2 As shown, the driving assembly 15 includes a driving motor 151 and a rotating shaft 152. The rotating shaft 152 is connected to the drum 12. Specifically, a first through hole is provided on the first end plate 121. A second through hole is provided on the second end plate 123. A third through hole is provided on the connecting rod. The first through hole, the second through hole and the third through hole are connected to form a through hole. The axis of the through hole wall is parallel to the axial direction of the drum 12. The aperture of the through hole is adapted to the diameter of the rotating shaft 152. The rotating shaft 152 is penetrated through the through hole. The driving motor 151 drives the rotating shaft 152 to rotate, and then the rotating shaft 152 drives the drum 12 to rotate.

[0079] On the second aspect, the utility model also provides an on-site air separation machine, including an air separation box 2, a conveying mechanism 3 and the discharge cleaning mechanism 1 as described above; the discharge cavity 111 is connected to the cavity of the air separation box 2, and the conveying mechanism 3 is arranged in the bottom area of ​​the air separation box 2, and the conveying mechanism 3 is used to convey the tobacco from the air separation box 2 to the discharge cavity 111.

[0080] Since the on-site air separator includes a discharge cleaning mechanism 1, and the specific structure of the discharge cleaning mechanism 1 refers to the above embodiment, the on-site air separator of this embodiment includes all the technical solutions of the above embodiment, and therefore has at least all the beneficial effects achieved by all the technical solutions of the above embodiment, which will not be repeated here one by one.

[0081] It is understandable that if Figure 1As shown, the on-site air separator also includes a feeding mechanism, a secondary air separation box 4, an air regulating mechanism 5 and a support leg 6. Among them, the support leg 6 is arranged at the bottom of the on-site air separator to support the entire device. The feeding mechanism is used to transport the tobacco to be processed to the air separation box 2. The air separation box 2 separates the tobacco from the impurities mixed therein by floating selection, and can break up the clumped tobacco.

[0082] Specifically, the shredded tobacco to be processed enters the air separation box 2 through the feeding mechanism. An air regulating mechanism 5 is provided on the side of the air separation box 2. The air regulating mechanism 5 can introduce lateral wind into the air separation box 2. Due to the differences in density and wind receiving area of ​​impurities and shredded tobacco in the shredded tobacco to be processed, the positions where the two fall under the action of the lateral wind are also different. Therefore, the wind direction and wind speed of the lateral wind of the air regulating mechanism 5 can be reasonably adjusted to control the separation accuracy.

[0083] The cavity of the secondary air separation box 4 is connected to the cavity of the air separation box 2, and can further process the tobacco shreds processed by the air separation box 2 to further improve the separation effect. Specifically, the secondary air separation box 4 adopts vertical air inlet to further screen and separate the tobacco shreds processed by the air separation box 2, so as to separate the fine impurities mixed in the tobacco shreds from the tobacco shreds, and discharge the overweight and oversized tobacco shreds from the outlet of the secondary air separation box 4.

[0084] like Figure 1 As shown, the conveying mechanism 3 is located in the bottom area of ​​the air separation box 2. The tobacco shreds separated by the air separation box 2 and the secondary air separation box 4 fall on the conveyor belt of the conveying mechanism 3. The conveyor belt conveys the tobacco shreds to the discharge chamber 111.
