Description

Technical Field

[0001] This utility model relates to a device for processing defective cigarettes, and more particularly to an online sorting device for defective cigarettes. Background Technology

[0002] When cigarette factories produce cigarettes, due to defects in raw materials, malfunctions in cigarette rolling equipment, or malfunctions in auxiliary material supply equipment, a certain amount of defective cigarettes will be generated, which have problems such as appearance defects, insufficient fullness and tightness of tobacco, unqualified splicing, and inconsistent draw resistance. In order to improve the utilization rate of raw materials, it is necessary to extract the tobacco from these defective cigarettes without damage and send them to the production line of cigarettes of the same grade for recycling.

[0003] Various methods exist for extracting residual tobacco from cigarettes on the market. However, each method requires the cigarettes to be arranged neatly. Cigarettes discarded by cigarette rolling machines are disordered and contain a certain number of irregularly shaped cigarettes. Therefore, it is necessary to tidy up the cigarettes and remove the irregularly shaped ones. The main method for tidying up cigarettes on the market is the single-vibration method. This method assembles multiple components into a single-vibration system based on the characteristics of single vibration. This single-vibration system can be roughly divided into receiving components, tidying components, and conveying components. However, in the single-vibration method, all components have the same vibration source, resulting in a uniform cigarette conveying speed, which can lead to excessive cigarette accumulation and blockage.

The technical solution is as follows: A defective cigarette online sorting device includes a primary conveying assembly, a secondary conveying assembly, a tertiary conveying assembly, an accelerating conveying assembly, and a cigarette output belt arranged sequentially on a frame.

[0010] The accelerated conveying assembly includes an upper feed shaft and a lower feed shaft arranged vertically. The left and right sides of the upper feed shaft and the lower feed shaft are respectively mounted on the left and right fixed seats of the feed shaft through bearings. The upper feed shaft and the lower feed shaft mesh with each other through gear transmission.

Detailed Implementation

[0014] like Figure 1 As shown, the online sorting device for defective cigarettes includes a primary conveying assembly 1, a secondary conveying assembly 2, a tertiary conveying assembly 3, an accelerating conveying assembly 4, and a cigarette output belt 5, which are installed on a frame 8 and arranged in sequence. The primary conveying assembly 1 is used to place scattered cigarettes 6. The scattered cigarettes 6 are sorted into axially output cigarettes 7 when they reach the secondary conveying assembly 2. The vibrators in the primary conveying assembly 1, the secondary conveying assembly 2, and the tertiary conveying assembly 3 are all independent mechanisms that can provide their own vibration sources, and the vibration source parameters are adjustable.

[0015] The primary conveying assembly 1, secondary conveying assembly 2, tertiary conveying assembly 3, accelerating conveying assembly 4, and cigarette output belt 5 are fixed at corresponding positions on the frame 8. The secondary conveying assembly 2 and the tertiary conveying assembly 3 have a distance of 21-30 mm in the length direction and a distance of 8-12 mm in the height direction.

[0016] like Figure 2 As shown, the primary conveying assembly includes a primary cigarette conveying plate 104. A primary vibrator 101 is fixedly installed at the bottom of the primary cigarette conveying plate 104. A left side baffle 102, a right side baffle 103, and a head end baffle 106 are installed around the periphery of the primary cigarette conveying plate 104. A quantitative cigarette conveying roller brush 105 is provided at the conveying end of the primary cigarette conveying plate 104. The primary cigarette conveying plate 104 is sinusoidal in shape, and the distance between the troughs and crests is approximately 2 mm.

[0017] The primary cigarette conveying plate 104 is fixed on the primary vibrator 101. The left side baffle 102 and the right side baffle 103 of the cigarette are located on the left and right sides of the primary cigarette conveying plate 104, respectively. The quantitative cigarette conveying roller brush 105 rotates clockwise at the tail end of the primary cigarette conveying plate 104 and is about 12mm above the horizontal plane of the primary cigarette conveying plate 104. The head end baffle 106 of the cigarette is located at the head end of the primary cigarette conveying plate 104.

[0018] like Figure 3As shown, the secondary conveying assembly includes a secondary cigarette sorting and conveying plate 203. A secondary direct vibrator 206 is installed on the underside of the secondary cigarette sorting and conveying plate 203. A left baffle 201 and a right baffle 202 of the secondary assembly are installed on the left and right sides, respectively. A cigarette sorting blocking block 204 and a cigarette sorting blocking pin 205 are provided on the surface of the secondary cigarette sorting and conveying plate 203.

[0019] The secondary cigarette sorting and conveying plate 203 is fixed on the secondary vibrator 206. The left baffle 201 and the right baffle 202 of the secondary component are located on the left and right sides of the secondary cigarette sorting and conveying plate 203, respectively. The secondary cigarette sorting and conveying plate 203 has a V-shaped structure with a 4 mm arc at the bottom and a distance of about 6 mm between the peak and the bottom. Four cigarette sorting blocking blocks 204 and twelve cigarette sorting blocking pins 205 are fixed on the peaks of the secondary cigarette sorting and conveying plate 203 and are arranged in a regular pattern.

[0020] The cigarette sorting and blocking block 204 is triangular in shape, and the cigarette sorting and blocking pin 205 is cylindrical with a hemispherical end face.

[0021] like Figure 4 As shown, the three-stage conveying assembly includes a three-stage cigarette conveying plate 303, a deformed cigarette cleaning plate 304, a deformed cigarette cleaning module 305, and a deformed cigarette chute 306. The three-stage cigarette conveying plate 303 is fixed on the three-stage vibrator 307, and a left baffle 301 and a right baffle 302 of the three-stage assembly are respectively installed on the left and right sides.

[0022] The deformable cigarette cleaning plate 304 lies horizontally on the three-stage cigarette conveying plate 303, and the distance between it and the plate is adjustable from 0 to 5 mm. The deformable cigarette cleaning module 305 is connected to the deformable cigarette cleaning plate 304, which serves as its power source, allowing the deformable cigarette cleaning plate 304 to move back and forth along the upper surface of the three-stage cigarette conveying plate 303. The deformable cigarette chute 306 is located below the three-stage cigarette conveying plate 303 and is fixed to the left baffle 301 and the right baffle 302 of the three-stage component.

[0023] The deformable cigarette cleaning module 305 can be a linear module. The slider of the linear module is fixedly connected to one side of the deformable cigarette cleaning plate 304. The linear module's drive motor drives the deformable cigarette cleaning plate 304 to move back and forth.

[0024] The upper part of the three-stage cigarette conveying plate 303 has a V-shaped structure, with a 13mm flat bottom and a peak about 6mm away from the flat surface. There is a 10mm diameter circular groove in the center of the flat surface.

[0025] like Figure 5As shown, the accelerated conveying assembly includes an upper feed shaft 404 and a lower feed shaft 405 arranged vertically. The left and right sides of the upper feed shaft 404 and the lower feed shaft 405 are respectively mounted on the left fixed seat 402 and the right fixed seat 403 of the feed shaft via bearings. The upper feed shaft 404 and the lower feed shaft 405 mesh with each other through gear transmission. The lower feed shaft 405 is connected to a drive motor 406 through one end of the upper feed shaft 404, serving as the power source for the two feed shafts. Cigarette restricting baffles 401 are installed at the front ends of the two feed shafts. The left and right sides of the cigarette restricting baffles 401 are respectively fixed to the left fixed seat 402 and the right fixed seat 403 of the feed shaft.

[0026] When using this utility model, the following steps are followed: S1: When the defective cigarettes discharged from the rejection port of the cigarette machine production line fall into the primary conveying component 1, the defective cigarettes discharged from the rejection port of the cigarette machine production line can be dispersed on the entire primary cigarette conveying plate 104 as scattered cigarettes 6 through the special structure of the primary cigarette conveying plate 104 and the action of the direct vibrator. If the amount of defective cigarettes discharged from the rejection port of the cigarette machine production line is too large and exceeds 100 cigarettes at one time, the cigarette quantitative conveying roller brush 105 will intercept part of the scattered cigarettes 6, so that all the scattered cigarettes 6 are not sent to the secondary conveying component 2 at one time. When a stray cigarette 6 falls onto the primary cigarette conveyor plate 104, the left side baffle 102, the right side baffle 103, and the head baffle 106 surround the primary cigarette conveyor plate 104 on three sides. The primary vibrator 101 provides forward movement for the cigarette, and the stray cigarette 6 can only move towards the tail end of the primary cigarette conveyor plate 104. When the amount of stray cigarette 6 falling is too large, the cigarette metering conveying brush 105 moves clockwise to block a certain amount of cigarettes, allowing only a small number of cigarettes to pass through.

[0027] S2: The secondary conveying component 2 contains multiple cigarette sorting and blocking blocks 204 and cigarette sorting and blocking pins 205, which sort the scattered cigarettes 6 into axially output cigarettes 7.

[0028] The cigarettes from the primary conveying assembly 1 are conveyed to the secondary conveying assembly 2 and fall onto the secondary cigarette sorting conveying plate 203. The secondary vibrator 206 provides the cigarettes with forward momentum and a slight vibration. The left and right baffles 201 and 202 of the secondary assembly block the left and right sides, preventing the cigarettes from falling off. As the secondary cigarette sorting conveying plate 203 moves forward, the scattered cigarettes 6 contact the cigarette sorting blocking block 204 and the cigarette sorting blocking pin 205. Because the contact is line contact, and the cigarettes move forward with slight vibration, and because the secondary cigarette sorting conveying plate 203 has a V-shaped structure, the scattered cigarettes 6, when landing on it, make point contact and are more likely to change direction. The scattered cigarettes 6 will tilt towards one side of the cigarette sorting blocking block 204 and the cigarette sorting blocking pin 205, thus transforming the scattered cigarettes 6 into axially output cigarettes 7.

[0029] The vibration-based sorting of the multiple cigarette sorting blocking blocks 204 and cigarette sorting blocking pins 205 is achieved by adding thin and narrow blocks or pins to the conveyor plate to intercept the cigarettes lying across the conveyor plate. Under the action of vibration and forward movement, the cigarettes lying across the plate will tilt to the left and right sides of the blocks or pins, thereby achieving the sorting effect.

[0030] The rejects from the cigarette machine production line are diverse, including severely deformed cigarettes, pieces of tipping paper, and unwrapped cigarette mouthpieces. The secondary conveyor assembly 2 cannot convert all of these into axial output.

[0031] S3: To handle severely deformed cigarettes, flakes of tipping paper, and unwrapped cigarette mouthpieces, a 21-30mm gap is reserved in the length direction and an 8-12mm gap in the height direction between the secondary conveying component 2 and the tertiary conveying component 3 as a rejection opening. The deformed cigarette cleaning plate 304 pushes these items into the opening, where they fall onto the deformed cigarette chute 306 and slide into the external collection box of the mechanism. Specifically, the rejects in the cigarette machine production line are diverse, including severely deformed cigarettes, flakes of tipping paper, and unwrapped mouthpieces. Flakes of tipping paper and unwrapped mouthpieces fall through the gap between the secondary conveyor assembly 2 and the tertiary conveyor assembly 3. Severely deformed cigarettes, due to their length, cannot be completely converted into axially output cigarettes 7 by the secondary conveyor assembly 2, and therefore need to be rejected. Due to the special structure of the tertiary cigarette conveyor plate 303, the axially output cigarettes 7 can move within its circular groove without being rejected by the deformed cigarette cleaning plate 304. Severely deformed cigarettes, due to changes in cylindricity, are easily blocked by the deformed cigarette cleaning plate 304 and pushed into the gap between the secondary and tertiary conveyor 305 by the movement of the deformed cigarette cleaning module 305, falling onto the deformed cigarette chute 306 and sliding into the external collection box.

[0032] S4: The axially output cigarette 7 falls from the secondary conveying assembly 2 into the tertiary conveying assembly 3 and is conveyed to the next assembly, the acceleration conveying assembly 4. The cigarette limiting baffle 401 restricts the passage of only one cigarette at a time through the acceleration conveying assembly 4. The two feed shafts mesh and move, giving the axially output cigarette 7 a forward thrust, which accelerates the axially output cigarette 7 forward.

[0033] S5: Finally, the axially output cigarette 7 is accelerated by the conveying assembly 4 and falls onto the cigarette output belt 5, where it is transferred to the cigarette collection box.

[0034] To prevent blockages during cigarette handling, the speed of each component is increased progressively. Specifically: the cigarette conveying speed of the first-stage conveying component 1 is less than that of the second-stage conveying component 2, which is less than that of the third-stage conveying component 3.

[0035] The online defective cigarette sorting device provided by this utility model, through multi-dimensional technical improvements, addresses the core pain points of traditional single-vibration sorting schemes, such as "cigarette accumulation and blockage, incomplete removal of irregularly shaped cigarettes, and low conveying efficiency," achieving a more efficient, refined, and stable defective cigarette sorting process. Specific technical effects are as follows: (1) Solve the problem of "cigarette accumulation and blockage" and improve the stability of the sorting process; Traditional single-vibration systems, due to the identical vibration sources and uniform conveying speeds of all components, are prone to cigarette accumulation in the conveying path, ultimately leading to equipment blockage and shutdown. This device, through a design of "multi-segment independent vibration + gradual speed increase," fundamentally avoids this defect. Independent adjustable vibration source: The direct vibrators (101, 206, 307) of the first, second and third stage conveying components are all independent mechanisms, and the amplitude, frequency and other parameters can be flexibly adjusted according to the amount of cigarettes conveyed, avoiding the problem of insufficient adaptability of a single vibration parameter; Speed ​​gradient design: Strictly following the gradient relationship of "first-level conveying speed < second-level conveying speed < third-level conveying speed", the cigarettes are always kept in a state of "no backlog in the previous stage and no gaps in the next stage" during the transmission process. Combined with the cigarette quantitative conveying roller brush 105 of the first-level component (which can intercept excessive cigarettes and avoid concentrated conveying of more than 100 cigarettes at a time), the risk of cigarette accumulation and blockage is completely eliminated, and the failure rate of continuous operation of the equipment is reduced.

[0036] (2) Achieve “efficient sorting of disordered cigarettes + precise removal of irregularly shaped cigarettes” to improve the purity of tobacco recycling; To address the issue of "disordered cigarettes + diverse impurities (deformed cigarettes, flakes of tipping paper, and unwrapped cigarette mouthpieces)" rejected by cigarette rolling machines, this device achieves a dual function of "sorting + rejection" through structural optimization, ensuring the purity and efficiency of subsequent tobacco extraction. High-efficiency axial sorting of disordered cigarettes: The secondary cigarette sorting conveyor plate 203 of the secondary conveying component adopts a V-shaped structure (4mm arc at the bottom of the valley and 6mm distance between the peak and the valley). Combined with the regular arrangement of cigarette sorting blocking blocks 204 and cigarette sorting blocking pins 205, the scattered cigarettes 6 are quickly transformed into axially output cigarettes 7 through "point contact direction change + line contact guidance" during vibration. The sorting efficiency is effectively improved compared with the traditional single vibration scheme. Multi-dimensional precise impurity removal: Utilizing a 21-30mm length gap + 8-12mm height gap between the secondary and tertiary components, small impurities such as flake tipping paper and unwrapped cigarette mouthpieces fall directly, initially filtering out non-cigarette-related impurities. The tertiary component's tertiary cigarette conveying plate 303 features a 13mm flat surface + 10mm diameter circular groove structure, working in conjunction with the deformed cigarette cleaning plate 304 (0-5mm adjustable spacing). This allows only qualified axially oriented cigarettes to pass through the circular groove, while deformed cigarettes are intercepted by the cleaning plate and pushed into the gap. This significantly reduces the impurity handling costs in subsequent tobacco extraction processes.

[0037] (3) Reduce the cost of manual intervention and improve the level of automation; Compared to a single vibration device, this device has lower manual maintenance costs, as it is directly connected to the rejection port of the production line and requires no secondary manual handling.
