DETAILED DESCRIPTION

[0024] The following is a specific implementation of the present application, and the technical solution of the present application is further described in combination with the drawings, but the present application is not limited to these embodiments.

[0025] A filter stick staggered drum wheel, as shown in Figure 1 from inside to outside, sequentially includes a main shaft 1, a shaft sleeve 2 sleeved on the main shaft 1, an air distribution valve 3 sleeved on the shaft sleeve 2, a wheel body 4 sleeved on the air distribution valve 3, and a tooth ring 5 sleeved on the wheel body 4. The tooth ring 5 is provided with six, and each two is a group. The angle between each group in the circumferential direction is 10°. In use, the air distribution valve 3 is fixed, the main shaft 1 drives the shaft sleeve 2, and then drives the wheel body 4, and then drives the tooth ring 5 to rotate.

[0026] Among them, in order to make the main shaft 1 drive the shaft sleeve 2 to rotate, the shaft sleeve 2 includes a mounting part 21 connected with the main shaft 1 through a flat key. Under the flat key structure, the shaft sleeve 2 and the main shaft 1 cannot rotate relative to each other. In some embodiments, in order to further avoid the axial movement of the shaft sleeve 2 affecting the rotation effect, the end of the main shaft 1 is threadedly connected with a locking nut 11, and the end of the shaft sleeve 2 abuts against the locking nut 11.

[0027] In order to enable the shaft sleeve 2 to drive the wheel body 4 and the gear ring 5 to rotate, first, the wheel body 4 is provided with a limiting portion 41 at one end and a connecting disc 42 at the other end, and the gear ring 5 is arranged between the limiting portion 41 and the connecting disc 42, so that the wheel body 4 and the gear ring 5 form an integral structure. In some embodiments, the connecting disc 42 is detachably connected with the wheel body 4, so that the gear ring 5 can be adjusted or replaced after the connecting disc 42 is detached. In some embodiments, the detachable connection is that the connecting disc 42 includes a ring-shaped covering portion sleeved on the wheel body 4 and a fixing portion abutting against the end of the wheel body 4, the fixing portion is connected with the end face of the wheel body 4 by a plurality of axial screws to realize detachable connection without affecting the installation of the gear ring 5, and the ring-shaped covering portion is used to abut against the gear ring 5. In some embodiments, the ring-shaped covering portion is detachably connected with the fixing portion, for example, the ring-shaped covering portion and the fixing portion can directly abut against each other, so that different ring-shaped covering portions with different axial lengths can be replaced to adapt to gear rings 5 with different axial lengths.

[0028] Secondly, the shaft sleeve 2 further includes a convex ring portion 22 arranged on the mounting portion 21, and the convex ring portion 22 is provided with a connecting hole. As shown in Figure 3 the fixing portion of the connecting disc 42 of the wheel body 4 is provided with a fan-shaped mounting hole 421 with the main shaft 1 as the center, and the central angle of the fan-shaped mounting hole 421 is preferably 15°. The shaft sleeve 2 and the wheel body 4 are connected by the connecting member 6 which is sequentially threaded through the fan-shaped mounting hole 421 and the connecting hole, and the connecting member 6 can be a screw. The provision of the fan-shaped mounting hole 421 enables the integral structure of the wheel body 4 and the gear ring 5 to rotate by a certain angle in the circumferential direction relative to the shaft sleeve 2 after the connecting member 6 is loosened, and then the integral structure is fixed by the connecting member 6, so that the position of the gear ring 5 in the circumferential direction is adjusted to better realize the transmission of the filter rod between the filter cutter and the displacement wheel. In some embodiments, in order to improve the fixing effect of the connecting member 6, a gasket is arranged between the stop head of the connecting member 6 and the connecting disc 42. Based on this, the fixing of the integral structure of the shaft sleeve 2, the wheel body 4 and the gear ring 5, and the circumferential adjustment of the integral structure of the wheel body 4 and the gear ring 5 relative to the shaft sleeve 2 are completed.

[0029] In some embodiments, due to the design of the fan-shaped mounting hole 421, the connecting piece 6 is only pressed by the hole wall in the radial direction in the fan-shaped mounting hole 421, and there is a gap between the hole wall in the circumferential direction and the fan-shaped mounting hole 421, which may cause the problem of relatively poor installation stability. Therefore, the connecting disc 42 is further designed to control the internal hollow of the fixed part of the connecting disc 42, and the internal hollow of the fan-shaped mounting hole 421 is not connected with the internal hollow. Specifically, the fixed part is first composed of two annular plates, a small-diameter sleeve ring and a large-diameter sleeve ring, and the annular plates, the small sleeve ring and the large sleeve ring are made of non-deformable material. Then, fan-shaped holes are formed on the two annular plates, respectively, and the ends of the two fan-shaped holes in the radial direction are connected by a non-deformable connecting plate, and the ends in the circumferential direction are connected by a deformable deformation part 422, such as latex. Based on this, a cavity is formed between the two annular plates, the small sleeve ring, the large sleeve ring, the connecting plate and the deformation part 422, and a gas member for introducing or extracting gas into the cavity is further included. By introducing gas into the cavity, the deformation part 422 can be deformed into the fan-shaped mounting hole 421 to press the connecting piece 6 in the circumferential direction, thereby improving the fixing effect.

[0030] In order to maintain the stability of the air distribution valve 3, as shown in Figure 1 and Figure 2 , one end of the air distribution valve 3 is provided with a flange plate 33 for connecting with the wall plate, and the other end is provided with an abutting part 34 for abutting with the convex ring part 22. The air distribution valve 3 is fixed by the flange plate 33 to avoid rotating with the shaft sleeve 2. In some embodiments, the distance from the surface of the abutting part 34 of the air distribution valve 3 to the surface of the mounting part 21 of the shaft sleeve 2 is greater than the distance from the surface of the convex ring part 22 to the surface of the mounting part 21, so that a half groove is formed between the abutting part 34 and the convex ring part 22. Correspondingly, the wheel body 4 is also provided with an inner convex part 43 which can be inserted into the half groove, and the cooperation of the half groove and the inner convex part 43 improves the stability of air distribution of the air distribution valve 3. In some embodiments, based on the premise that the fixed part is detachably connected with the end surface of the wheel body 4 by a plurality of axial screws, the fixed part is connected with the inner convex part 43 of the wheel body 4 by axial screws. The provision of the inner convex part 43 increases the thickness of the end surface of the wheel body 4, and improves the connection stability between the two.

[0031] In addition, in order to realize air distribution, the air distribution valve 3 is provided with a negative pressure air duct 31, and the wheel body 4 and the gear ring 5 are provided with air holes which can communicate with the negative pressure air duct 31; at the same time, as shown in Figure 2 , the gear ring 5 is provided with a smoke slot 51 which communicates with the air hole. When the overall structure of the wheel body 4 and the gear ring 5 rotates to the position where the air hole communicates with the negative pressure air duct 31, the filter rod coming from the upstream is adsorbed by the negative pressure of the smoke slot 51 and rotates together; after rotating for a certain angle, when the air hole of the overall structure of the wheel body 4 and the gear ring 5 can no longer communicate with the negative pressure air duct 31, the smoke slot 51 can no longer adsorb the filter rod, and the filter rod falls and is caught by the downstream drum, completing the transfer work of the filter rod.

[0032] In some embodiments, the air distribution valve 3 is further provided with a positive pressure air channel 32, and the air holes of the wheel body 4 and the tooth ring 5 can communicate with the positive pressure air channel 32. When the filter rod is transferred to the downstream wheel drum, the air holes of the wheel body 4 and the tooth ring 5 are instantaneously connected with the positive pressure air channel 32 on the air distribution valve 3, so as to remove the ash in the air holes and keep the air holes clean and unobstructed.

[0033] In some embodiments, the slot wall of the smoke slot 51 is an arc with a central angle of 120°, so that when the filter rod is transferred, the tangent of the wheel slot vertex to the direction of the filter rod entering and separating the wheel body is 90°, there is no circumferential component force interference, the transfer is more stable, and the maintenance process is greatly simplified, the operation efficiency and product quality are improved.

[0034] The specific embodiments described herein are merely illustrative of the spirit of the present application. Those skilled in the art to which the present application belongs can make various modifications or supplements to the described specific embodiments or replace them with similar ways, without departing from the spirit of the present application or exceeding the scope defined by the appended claims.
