[0035] Example

[0036] Reference Figure 1-5 The present embodiment provides a residual tobacco separation device, comprising a vibrating plate, the vibrating plate comprising a feeding channel 1 which spirally ascends (along the conveying direction) and a separation channel which spirally descends (along the conveying direction) and is arranged on the periphery of the feeding channel 1. The feeding channel 1 and the separation channel are both arranged in a clockwise direction (such as Figure 2 Transport in the direction (as shown in the top view).

[0037] The cigarettes are arranged in a row (connected head to head, head to head or tail to tail) in the feeding channel 1 and transported upward. The outlet end of the feeding channel 1 extends outward to form a cutting channel 2. Cutting components 5 are mirror-imaged on both sides of the cutting channel 2. When the cigarettes pass through the cutting components 5, the cigarette paper is cut from both sides.

[0038] The separation channel includes a tobacco screen 3 and an auxiliary material channel 4 in sequence. The tobacco screen 3 is located directly below the cutting channel 2. A collection box 6 is provided below the tobacco screen 3. The area of ​​the collection box 6 is larger than the area of ​​the tobacco screen 3, so that all tobacco dropped from the tobacco screen 3 can be collected by the collection box 6. The output end of the collection box 6 is connected to a tobacco hopper 7, which is located at the bottom of the lower end of the collection box 6. The output end of the tobacco hopper 7 is connected to a negative pressure pipe 8, through which the separated tobacco is directly transported to the rolling unit for production. The output end of the auxiliary material channel 4 is provided with a drop port, which is connected to a collection channel, which can be a collection pipe or a guide groove, through which the auxiliary materials (filter tip and cigarette paper) are discharged outward.

[0039] The cigarettes cut by the cutting assembly 5 fall from the cutting channel 2 to the tobacco screen 3. The tobacco and other cigarette accessories (filter and cigarette paper) are separated by the vibration of the tobacco screen 3. The tobacco falls from the tobacco screen 3 to the collection box 6, and then is directly transported to the cigarette making unit through the tobacco hopper 7 for production. The cigarette accessories are transported to the accessories channel 4 along the tobacco screen 3 and discharged from the drop port.

[0040] The cutting assembly 5 comprises a roller cutter 51, a cutting motor 52 and a fixing seat 53. The inner end of the fixing seat 53 is fixedly connected to the outer side of the cutting channel 2. The roller cutter 51 is installed above the fixing seat 53. The motor is installed below the fixing seat 53 and is connected to the roller cutter 51 in a transmission manner. The roller cutter 51 is located at the two outer sides of the cutting channel 2. The roller cutter 51 is driven by the cutting motor 52 to rotate to cut cigarette paper. The width of the cutting channel 2 allows only one cigarette to pass through. Baffles 21 are provided on both sides of the cutting channel 2. Notches 22 adapted to the edges of the roller cutter 51 are provided on the baffles 21. The edges of the roller cutter 51 are located in the notches 22. The distance between the blades of the two roller cutters 51 is slightly smaller than the diameter of the cigarette, so that the roller cutter 51 only cuts the cigarette paper without damaging the internal tobacco, thereby ensuring the quality of the tobacco and reducing the fragmentation of the tobacco, so that the separated tobacco does not need to be downgraded and can be directly applied to the cigarette making unit. In addition, the device is still applicable to cigarettes with burst beads. When cutting the two sides of the filter tip, the burst beads will not be damaged. The burst beads are still inside the filter tip, and the burst beads and the filter tip are collected together.

[0041] The above-mentioned roller cutter 51 includes a roller 511, and the side edge of the roller 511 is concave inward to form an arc-shaped clamping part 5111 adapted to the cigarette. An alloy circular blade 512 is detachably installed in the middle of the arc-shaped clamping part 5111. The circular blade 512 is on the same horizontal plane as the central axis of the cigarette to be cut. The roller 511 is driven to rotate by the cutting motor 52, so that the circular blade 512 rotates to cut the cigarette paper. When the cigarette passes through the cutting assembly, the cigarette is clamped and conveyed forward by the arc-shaped clamping part 5111, and the two sides of the cigarette are cut simultaneously by the circular blade 512. Specifically, the cutting effect can be controlled by replacing the circular blades 512 with different outer diameters or the distance between the two rollers 5111, so as to ensure that the cigarette paper is cut while reducing the damage to the tobacco.

[0042] The distance between the two roller cutters 51 is adjustable, and the height of the roller cutters 51 is also adjustable to adapt to the cutting of cigarette paper for cigarettes of different diameters. In addition, by adjusting the distance between the two roller cutters 51, the roller cutters 51 can smoothly cut the cigarette paper while ensuring the quality of the shredded tobacco. Specifically, a waist-shaped hole 531 is provided on the fixing seat 53, and the distance between the roller cutters 51 can be adjusted through the waist-shaped hole 531.

[0043] The diameter of the circular holes of the above-mentioned tobacco screen 3 is Φ6 mm. The tobacco screen 3 of this size can screen out tobacco of all lengths and ensure that other cigarette auxiliary materials pass through the tobacco screen 3 and enter the auxiliary material channel 4.

[0044] The working process of this embodiment is as follows:

[0045] The distance between the roller cutters 51 on both sides of the cutting channel 2 is adjusted to adapt to the diameter of the cut cigarette, that is, the distance between the blades of the two roller cutters 51 is slightly smaller than the diameter of the cigarette, so that the cigarette paper can be cut smoothly while ensuring the quality of the shredded tobacco.

[0046] The vibration plate is started to generate a certain frequency of vibration, and the cigarettes are transported upward along the feeding channel 1 and transported in a row to the cutting channel 2. When the cigarettes pass through the roller cutter 51, the cigarette paper is axially cut from both sides by the cutting assembly 5.

[0047] The cut cigarettes fall into the tobacco screen 3, and the tobacco screen 3 is vibrated to separate the tobacco from other cigarette accessories (filter and cigarette paper).

[0048] The separated tobacco falls from the tobacco screen 3 into the collecting box 6, and is concentrated and adsorbed into the tobacco hopper 7 through the negative pressure channel and directly transported to the rolling and connecting unit for production; the separated cigarette auxiliary materials are vibrated along the tobacco screen 3 and transported to the auxiliary material channel 4 and discharged from the collection channel.

[0049] It should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
