Example 1

Referring to fig. 1, 10 and 11, the rotary distribution mechanism 200 of the present embodiment includes a hopper 210, a distribution bin 260 and a driving motor 230, wherein the distribution bin 260 includes a feeding port at an upper end thereof and a plurality of distribution ports 261 arranged along a circumferential direction thereof at a lower end thereof, the hopper 210 is driven to rotate along a center line of the distribution bin 260 by the driving motor 230, i.e., along a normal line of a geometric center of a lower side surface of the distribution bin 260, and the discharge port 214 of the hopper 210 is engaged with the plurality of distribution ports 261, so as to achieve the purpose of distributing materials to the distribution ports 261.

To achieve the above purpose, the discharge port 214 of the hopper 210 of this embodiment should be offset from the geometric center of the lower side of the discharge port 261. The hopper 210 can be a common hopper, i.e. a funnel-shaped container with a large top and a small bottom, and a guide groove is arranged at the discharge port 214 thereof, so that the cut tobacco can deviate from the center line of the feed port 212 of the hopper 210 when the hopper 210 discharges; referring to fig. 2, 3 and 4, the hopper 210 may also be an eccentric hopper with the discharge outlet 214 offset from the centerline of the feed inlet 212. In addition, the shape and the position of the material distributing opening 261 of the material distributing bin 260 should match with the material outlet 214 of the hopper 210, and the size of the material distributing opening 261 should be not smaller than the size of the material outlet 214 of the hopper 210, so that when a certain material distributing opening 261 is used for distributing materials, the cut tobacco cannot be mistakenly fed into other material distributing openings. The plurality of material distributing openings 261 can be uniformly distributed on the circumferential direction of the lower side surface of the material distributing bin 260, and the working time of the driving motor 230 can be controlled during material distribution, so that the rotating angle of the hopper 210 is controlled, and finally the material outlet 214 and the material distributing openings 261 are matched all the time.

Specifically, referring to fig. 6, a cylindrical vertical section may be disposed on a side surface of the hopper 210, and the hopper 210 is connected to the driving wheel 231 through a belt, and when the driving motor 230 operates, the driving wheel 231 drives the hopper 210 to rotate through the belt, so as to realize batching; referring to fig. 7, a gear ring 211 may be provided on the vertical section to link the driving wheel 231 with the hopper 210 by a chain, and to transmit the driving force of the driving motor 230 to the hopper 210 to rotate the hopper 210; referring to fig. 1, a gear transmission mode may be directly adopted, and the driving wheel 231 is a gear and is engaged with a gear ring 211 on the side surface of the hopper 210 to drive the hopper 210 to rotate.

It should be noted that the gear ring 211 can be arranged according to the shape of the hopper 210, when the upper end of the hopper 210 comprises a cylindrical vertical section, the gear ring 211 can be arranged along the vertical section, the gear ring 211 should be fixedly connected with the vertical section, and the gear ring 211 and the feed inlet 212 of the hopper 210 maintain high concentricity; when the side surface of the hopper 310 does not comprise a cylindrical vertical section, the center of the gear ring 211 and the center of the feeding port 212 of the hopper 210 should keep high concentricity, so that the hopper 210 only has the freedom of rotating along the central line thereof, and the relative positions of the feeding port 212 and the material distribution bin 260 are not changed.

Further, in order to support the hopper 210 to be more stable in rotation, referring to fig. 4, a rotation shaft 213 may be provided at a side surface of the hopper 210, and the rotation shaft 213 may be provided on a center line of the feed port 212. The rotating shaft 213 is fixedly disposed on a side surface of the hopper 210, and the rotating shaft 213 may be fixedly connected to an outer side surface of the hopper 210 by contacting the outer side surface, or may penetrate through the side surface of the hopper 210 and extend into the hopper 210.

The rotation axis of the support wheel 240 is arranged obliquely so that the support wheel 240 leans against the vertical section of the hopper 210, i.e. the support force provided by the support wheel 240 to the hopper 210 is oblique. When the hopper 210 rotates, the supporting force in the vertical direction provided by the supporting wheels 240 can support the hopper 210, and the force in the horizontal direction provided by the supporting wheels 240 can limit the degree of freedom of movement in the horizontal direction when the hopper 210 rotates, so that the hopper 210 rotates more stably, and the vibration amplitude of the hopper is reduced.

It should be noted that the rotating shaft 213 and the supporting wheels 240 of the present embodiment can both support the hopper 210 and maintain the rotational stability of the hopper 210, and one of the rotating shaft 213 and the supporting wheels 240 can be selected according to the size, shape and installation site of the hopper 210, or the two can be combined to make the rotational stability of the hopper 210 higher, so as to reduce the noise generated during rotation, reduce the wear of the hopper 210, and prolong the service life thereof.

When the rotary distribution mechanism 200 is provided with a plurality of auxiliary wheels 250, the auxiliary wheels 250 may be uniformly distributed in the circumferential direction of the ring gear 211 of the hopper 210. When the hopper 210 rotates, the gear ring 211 drives the auxiliary wheel 250 to rotate, so that the concentricity of the hopper 210 during rotation can be maintained.

In the cigarette production process, the cleanliness of the cut tobacco should be maintained, so as to further optimize the embodiment, a dust cover 220 may be disposed on the hopper 210, and the dust cover 220 covers the upper port of the dispensing bin 260 to prevent dust or impurities from entering the dispensing bin 260 and polluting the cut tobacco. Referring to fig. 3, the dust cover 220 may be attached to the discharge port 214 of the hopper 210, and a hole matching with the discharge port 214 is formed in the dust cover 220, and referring to fig. 1, the discharge port 214 of the hopper 210 further includes a connecting plate, the discharge port 214 is aligned with the hole formed in the dust cover 220, and the dust cover 220 is connected to the connecting plate of the discharge port 214 by riveting, welding, screwing, and the like, so that the dust cover 220 is fixed on the hopper 210; the dust cover 220 can also be arranged on the discharge port 214, that is, the discharge port 214 penetrates through a hole formed in the dust cover 220 and extends into the material distribution bin 260, and the dust cover 220 and the discharge port 214 are fixedly connected in a riveting manner, a welding manner and the like, and can also be detachably connected in a threaded connection manner and the like; similarly, the dust cover 220 may be provided on the outer side surface of the hopper 210.
