[0002] Cigarettes are tobacco products made by rolling tobacco into strips with cigarette paper, also known as paper cigarettes, cigarettes, cigarette rolls, cigarette sticks, etc. In the production process of cigarette sticks, there will be extra-long waste cigarettes that are much longer than standard cigarette sticks. The extra-long waste cigarettes cannot smoothly enter the flow channel during the subsequent sorting and packaging process. Therefore, it is necessary to sort the extra-long waste cigarettes and standard cigarette sticks to remove the extra-long waste cigarettes mixed in the standard cigarette sticks.

[0003] In the related art, the method for sorting extra-long cigarettes is as follows: the cigarettes to be sorted are fed into a circular vibrating plate, which is vibrated and fed through the circular vibrating plate, and then the cigarettes are diverted by the circular vibrating plate, and the cigarettes are adjusted into a single arrangement pattern in the flow channel. Finally, a sorting hole matching the size of standard cigarettes is set at the bottom of the flow channel. The standard cigarettes are collected again after passing through the sorting hole, while the extra-long waste cigarettes cannot pass through the sorting hole and continue to be transported along the flow channel, thereby achieving the sorting of extra-long waste cigarettes and standard cigarettes.

[0004] However, this sorting method requires the cigarettes to be adjusted to be delivered individually first, and the sorting efficiency is low. Utility Model Content

[0036] The utility model provides a material sorting vibration plate, which includes a bottom plate and side plates arranged on opposite sides of the bottom plate, the two side plates cooperate with the bottom plate to form a flow channel, and the flow channel can accommodate multiple materials to be sorted at the same time; a plurality of through holes are arranged through the bottom plate, the apertures of the through holes match the standard materials and are connected to the flow channel; the flow channel is divided into a first area, a second area and a third area in sequence along the conveying direction of the material; the through holes are opened in the first area, the second area and the third area, and a convex point is opened on the bottom plate at the second area. In the material sorting vibration plate, the two side plates cooperate with the bottom plate to form the flow channel that can accommodate multiple materials to be sorted at the same time, and the bottom plate is provided with the through hole. During sorting, the materials to be sorted can be directly sent into the flow channel, and the materials are sorted by the vibration of the material sorting vibration plate, so that the standard materials can flow out of the flow channel through the through hole, while the extra-long materials continue to be transported along the flow channel, thereby realizing the sorting of materials, and there is no need to perform pre-sorting operations on the materials, which can greatly improve the efficiency of sorting. In addition, the convex point is provided on the bottom plate of the second area, and the convex point can increase the resistance of the material flowing through the flow channel, and prevent the material from directly rolling to the end of the flow channel under the action of the initial kinetic energy. At the same time, the direction of the material can be changed through the collision effect, so that the material is adjusted from horizontal to vertical, and it is easier to fall through the through hole.

[0037] Please refer to Figures 1 to 5 In one embodiment, a material sorting vibration plate 100 is provided for conveying and sorting materials by vibration. Specifically, in one embodiment, the material is cigarettes, and the material sorting vibration plate 100 is a cigarette sorting vibration plate for conveying and sorting standard cigarettes (length within the standard range) and extra-long cigarettes (length exceeding the standard range).

[0038] The material sorting vibration plate 100 includes a bottom plate 10 and side plates 20 disposed on opposite sides of the bottom plate 10 . The two side plates 20 cooperate with the bottom plate 10 to form a flow channel 30 . The flow channel 30 can simultaneously accommodate multiple materials to be sorted.

[0039] The bottom plate 10 is provided with a plurality of through holes 11, the apertures of the through holes 11 match the diameters of the standard materials and are connected to the flow channel 30. The apertures of the through holes 11 match the diameters of the standard materials, which means that the apertures of the through holes 11 are not less than the diameters of the standard materials, and the apertures of the through holes 11 are not greater than the lengths of the extra-long materials, so that when the standard materials are in a specific state, they can flow out of the flow channel 30 through the through holes 11, while the extra-long materials are not easy to flow out of the through holes 11, thereby achieving the separation of the standard materials and the extra-long materials.

[0040] When the material sorting vibration plate 100 is in use, multiple materials to be sorted can be directly fed into the flow channel 30, and the material sorting vibration plate 100 can drive the materials to vibrate synchronously, thereby changing the state of the materials. When the standard material is vibrated to a nearly vertical state, it can fall out of the flow channel 30 through the through hole 11, while the extra-long material continues to be transmitted along the flow channel 30, thereby realizing the sorting of the materials, without the need for pre-sorting operations on the materials, which can greatly improve the efficiency of sorting.

[0041] The flow channel 30 is divided into a first area 31, a second area 32 and a third area 33 along the material conveying direction. The first area 31, the second area 32 and the third area 33 are all provided with the through holes 11, and the bottom plate 10 in the second area 32 or the third area 33 is provided with a protrusion 12.

[0042] It is understandable that no structure is set at the edge of the through hole 11 in the first area 31. The reason is that the first area 31 is close to the direction of the material, and a large amount of material is transported from the inclined conveyor belt. Once a protruding structure is set at the edge of the through hole 11 in the first area 31, it is easy to cause the material to be blocked and retained in the first area 31 and unable to enter the second area 32 and the third area 33; and the retained materials will squeeze each other, change the direction of the overlong material, and make it easy to become vertical and fall directly from the through hole 11. Therefore, a relatively smooth surface needs to be maintained in the first area 31 to ensure the smooth flow of materials. Under the action of vibration, the standard material falls through the through hole 11, while the overlong material is retained in the flow channel 30 and continues to be transported forward.

[0043] After the material is transported by the conveyor belt, it has a certain initial kinetic energy, and the vibration of the material sorting vibration plate 100 will also provide a certain amount of power to the material. Once the material is oriented horizontally, the sliding friction between the material and the bottom plate 10 changes to rolling friction, which greatly reduces the resistance, making it easy for the material to roll quickly directly on the bottom plate 10 to the end of the flow channel 30, and not easy to enter the through hole 11. Since the cigarette is cylindrical, when the cigarette flows into the flow channel 30, it is easier to roll directly to the end of the flow channel 30 under the action of the initial kinetic energy. The convex point 12 is set at the second area 32 or the third area 33 to increase the resistance of the material in the flow channel 30, and prevent the material from rolling directly to the end of the flow channel 30. At the same time, the direction of the material can be changed through the collision effect, so that the material is adjusted from horizontal to vertical, and it is easier to fall through the through hole 11, so as to better ensure the sorting effect.

[0044] After being sorted in the first area 31, a large amount of standard materials fall through the through hole 11 of the first area 31, and the remaining over-long materials and a small amount of standard materials enter the second area 32 and the third area 33. After being hit by the convex point 12, the direction of the horizontally transmitted standard materials changes to inclined or vertical transmission, making it easier to fall through the through hole 11 of the second area 32; and after hitting the convex point 12, part of the energy will be dissipated, making it difficult for the materials to roll directly to the end of the flow channel 30.

[0045] It should be noted that the material sorting vibration plate 100 needs to be connected to a vibrator when in use, and the vibrator drives the vibration to provide power for conveying the material in the flow channel 30. Conventional technology in the art can be used, and this embodiment will not be described in detail.

[0046] Preferably, in one embodiment, the convex point 12 is only arranged at the second area 32, and the convex point 12 is arranged close to the edge of the through hole 11 at the second area 32, and is located on the side close to the direction of the material. That is to say, the through hole 11 and the convex point 12 at the second area 32 are arranged in such a way that the convex point 12 is located at the front side of the through hole 11, so that when the material flows into the second area 32, it will first flow through the convex point 12, and then flow through the through hole 11 after being blocked by the convex point 12. Through this structure, the direction of the standard material can be better changed through the collision effect, so that the standard material can be more easily dropped through the through hole 11 at the second area 32.

[0047] Preferably, in one embodiment, the convex point 12 is arranged in a one-to-one correspondence with the through hole 11 at the second region 32, and the convex point 12 is a hemispherical convex point. That is to say, in this embodiment, a plurality of the through holes 11 and a plurality of the convex points 12 are arranged at the second region 32, and the plurality of the convex points 12 are arranged in a one-to-one correspondence with the plurality of the through holes 11, so that the sorting efficiency can be further improved. In addition, the convex point 12 has a hemispherical structure with smooth transitions at various places on the surface, which can alleviate the stress concentration phenomenon after the material collides with the convex point 12 on the one hand, and avoid the material from breaking; on the other hand, it can divergently adjust the direction of the material to avoid the material after the collision from gathering in a single direction to form a blockage.

[0048] Preferably, in one embodiment, a baffle 13 is provided on the bottom plate 10 at the third area 33. By setting the baffle 13, the vertical materials can be blocked, so that the standard materials can smoothly fall through the through hole 11, and the overlong materials are intercepted by the baffle 13. By combining the baffle 13 with the convex point 12, the separation of standard materials and overlong materials can be better achieved, and all materials are synchronously sorted in the material sorting vibration plate 100, without the need for pre-sorting operations, which can greatly improve the efficiency of sorting.

[0049] Preferably, in one embodiment, the baffle 13 is arranged close to the edge of the through hole 11 at the third area 33 and is located on the side away from the direction of the material. That is, the through hole 11 and the baffle 13 at the third area 33 are arranged in such a manner that the baffle 13 is located at the rear side of the through hole 11. With this structure, the standard material can be dropped through the through hole 11 more smoothly.

[0050] Preferably, in one embodiment, the baffle 13 is arranged in one-to-one correspondence with the through hole 11 in the third area 33. The baffle 13 is an arc-shaped baffle, and the central angle corresponding to the baffle 13 ranges from 60° to 90°. That is to say, in this embodiment, a plurality of through holes 11 and a plurality of baffles 13 are arranged in the third area 33, and the plurality of baffles 13 are arranged in one-to-one correspondence with the plurality of through holes 11, thereby further improving the sorting efficiency. And the baffle 13 is an arc-shaped structure, thereby improving the blocking and interception effect on the standard material.

[0051] Preferably, in one embodiment, the height of the protrusion 12 is equal to that of the baffle 13, and the height H of the protrusion 12 and the diameter D of the standard material satisfy the following conditions:

[0052] 1 / 3D≤H≤1 / 2D.

[0053] Through this structure, the standard materials can be better guided to fall from the through hole 11, thereby improving the sorting effect, while not excessively hindering the conveyance of the extra-long materials to the rear side.

[0054] Preferably, in one embodiment, the aperture d of the through hole 11 and the length L of the standard material satisfy the following conditions:

[0055] 1 / 2L≤d≤L.

[0056] Through this structure, the sorting effect can be further ensured.

[0057] After sorting in the second area 32, the remaining overlong materials and a small amount of standard materials enter the third area 33, and the ends of the materials touch the baffle 13 and are intercepted by the baffle 13. When the intercepted materials are standard materials, due to the relationship between the aperture of the through hole 11 and the length of the materials, the center of gravity of the standard materials is located within the range of the through hole 11, and under the dual effects of vibration and gravity, the end of the standard cigarette close to the baffle 13 falls into the through hole 11; and when the intercepted materials are overlong materials, the center of gravity of the overlong materials is located outside the range of the through hole 11, and can maintain a high stability, be carried on the bottom plate 10, and cannot fall from the through hole 11, so they are retained on the bottom plate 10, and the separation of standard materials and overlong materials is achieved.

[0058] Preferably, in one embodiment, the distance between two adjacent through holes 11 in the first area 31 is a, the distance between two adjacent through holes 11 in the second area 32 is b, and the distance between two adjacent through holes 11 in the third area 33 is c, and a, b, and c satisfy the following conditions:

[0059] a>b>c.

[0060] Through this structure, the sorting efficiency can be further improved.

[0061] The material sorting vibration plate 100 combines two material blocking methods through the setting of the protrusion 12 and the baffle 13, so as to better realize the sorting of standard materials and extra-long materials. All materials are sorted synchronously in the material sorting vibration plate 100 without the need for pre-sorting operations, which can greatly improve the sorting efficiency and realize the sorting of a maximum of 180 kilograms of materials per hour.

[0062] Please refer to Figure 6 . In one embodiment, a vibration plate assembly 1000 is also provided, which includes two layers of the material sorting vibration plates 100 arranged in parallel and spaced apart, the feeding ends of the two layers of the material sorting vibration plates 100 are aligned, and the length of the flow channel 30 of the material sorting vibration plate 100 located at the bottom is greater than the length of the flow channel 30 of the material sorting vibration plate 100 located at the top. The sorting rate of standard materials and over-long materials can be improved by a two-layer sorting method. The initially sorted standard materials are collected from under the through hole 11 of the material sorting vibration plate 100 located at the bottom, for example, collected by a collection bucket, or directly collected by a conveyor belt and transported to a subsequent process.

[0063] The above is only an implementation method of the present invention. It should be pointed out that a person skilled in the art can make improvements without departing from the inventive concept of the present invention, but these improvements are all within the protection scope of the present invention.
