Description

Technical Field

[0001] The invention relates to the technical field of waste smoke collection and separation recovery, and in particular to a waste smoke collection and separation recovery device for a cigarette making machine. Background Art

[0002] During the production process of the ZJ17 cigarette making machine, unqualified cigarettes may be produced due to tobacco quality problems, cigarette making machine failures, improper operation and improper adjustment. The unqualified cigarettes are rejected by the waste smoke solenoid valve and fall into the waste smoke collection box under the drum wheel due to gravity for collection so that they can be processed later.

[0003] In the Chinese patent with publication number CN115736333A, a waste smoke collection and separation and recovery device for a cigarette making machine is mentioned, including a protective cover, a drive motor, a conveyor roller, a conveyor belt, a separation chamber, an air suction hood, a tobacco collection box and a mouthpiece collection box; the protective cover is located around the conveyor belt, the drive motor is located on the side of the protective cover, the conveyor roller is installed below the drum wheel of the filter tip assembling machine of the ZJ17 cigarette making machine and is connected to the power of the drive motor, the conveyor roller cooperates with the conveyor belt, the separation chamber is located below one end of the conveyor belt, a suction hood is arranged above the separation chamber, the mouthpiece collection box is located below the separation chamber, and the tobacco collection box is located below the mouthpiece collection box. On one side of the box, the tobacco collection box is connected to the top of the suction hood. The invention is composed of a plurality of rollers that are staggered with each other and are close to the upper surface of the conveyor belt through a rolling roller. The residual smoke on the conveyor belt can be crushed multiple times to facilitate the separation of the mouthpiece and the tobacco part of the residual smoke. After separation, they enter the separation chamber. Above the separation chamber is the suction hood. Due to the different weights of the mouthpiece and the tobacco in the residual smoke mixture, the mouthpiece with a smaller weight falls to the mouthpiece collection box below, and the tobacco with a smaller weight is sucked up by the suction hood and enters the suction duct. The negative pressure generator provides negative pressure for the suction hood and the suction duct. After entering the suction duct, the tobacco will be conveyed to the tobacco collection box.

[0004] However, in daily use, placing cigarettes directly under the rolling roller for rolling will most likely only flatten the cigarettes instead of separating the tobacco from the cigarette butts and cigarettes, so the tobacco separation effect of this scheme is poor; tobacco and cigarette butts are relatively light in weight, and directly using a negative pressure generator and a suction hood to separate the tobacco and cigarette butts will most likely suck all the cigarette butts and tobacco into the tobacco collection box, further resulting in poor separation effect of this scheme and increasing the workload of subsequent manual screening. Summary of the invention

[0005] The object of the present invention is to provide a device for collecting, separating and recovering waste smoke from a cigarette making machine, so as to solve the problems raised in the above-mentioned background technology.

[0006] To achieve this object, the present invention adopts the following technical solutions:

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0039] like Figures 1 to 8 As shown, the present invention provides a device for collecting, separating and recovering waste smoke from a cigarette making machine.

[0040] Embodiment 1

[0041] The present invention provides a waste cigarette collection and separation recovery device for a cigarette making machine, comprising a collection mechanism 100 , wherein the collection mechanism 100 comprises a support groove 101 , and a lower hopper 106 is fixedly mounted at the front end of the support groove 101 .

[0042] The collecting mechanism 100 includes a driving shaft 102 which is rotatably arranged inside a supporting groove 101, a driving motor 103 is fixedly installed at one end of the driving shaft 102, and the driving motor 103 is fixedly installed on one side of the supporting groove 101. A transmission belt 104 is transmission-connected to the outer surface of the driving shaft 102, and a driven shaft 105 is transmission-connected inside the transmission belt 104. The driven shaft 105 is rotatably connected to the supporting groove 101.

[0043] As can be seen from the above, by installing the collection mechanism 100 below the drum wheel of the filter assembler of the ZJ17 cigarette making machine, the rear end of the transmission belt 104 is placed directly below the waste smoke outlet. When waste smoke is discharged, the waste smoke falls onto the transmission belt 104, and the drive motor 103 is started to drive the driving shaft 102 to rotate, and then the transmission belt 104 rotates. The transmission belt 104 carries the waste smoke into the lower hopper 106 for collection, waiting for subsequent processing.

[0044] Embodiment 2

[0045] The second embodiment of the present invention comprises a crushing mechanism 200 , wherein the crushing mechanism 200 comprises a crushing box 201 fixedly connected to the lower end of the lower hopper 106 , and a driving assembly is arranged inside the crushing box 201 .

[0046] The driving assembly includes two crushing rollers 202 that are relatively rotatable and penetrate the inside of the crushing box 201. A number of crushing blades 203 are evenly and fixedly installed on the outer surfaces of the two crushing rollers 202. Pulleys 204 are fixedly installed at the front ends of the two crushing rollers 202. The two pulleys 204 are connected through a transmission belt 205. A rotating motor 206 is fixedly installed at the front ends of the pulleys 204. The rotating motor 206 is fixedly installed on one side of the crushing box 201.

[0047] As can be seen from the above, the waste smoke enters the crushing box 201 through the lower hopper 106, and the rotating motor 206 is started. The rotating motor 206 and the transmission belt 205 cooperate to make the two pulleys 204 rotate at the same time, and then drive the two crushing rollers 202 to rotate respectively. The crushing blades 203 cooperate to generate shear force, and the waste smoke that falls on the crushing blades 203 is crushed, so that the cigarette paper is broken, and then the tobacco shreds and cigarette butts in the waste smoke are separated, and the crushing and separation effect is better.

[0048] Embodiment 3

[0049] The third embodiment of the present invention comprises a separation mechanism 300, which comprises two support frames 301 relatively fixedly installed at the lower end of the crushing box 201, wherein a fixing plate 302 is fixedly installed inside the two support frames 301, and a shaking assembly is arranged inside the two support frames 301.

[0050] The shaking assembly includes two elastic members 303 relatively fixedly installed on both sides of the fixed plate 302, the front ends of the two elastic members 303 are fixedly installed with sliding grooves 304, the two sliding grooves 304 are both slidably connected to the support frame 301, the front sides of the two sliding grooves 304 are fixedly installed with springs 305, and the two springs 305 are respectively fixedly connected to the two sides inside the support frame 301.

[0051] A motor 306 is fixedly installed inside the sliding groove 304, and a rotating shaft 307 is fixedly installed at the output end of the motor 306. The rotating shaft 307 is rotatably arranged inside the sliding groove 304. An eccentric linkage rod 308 is connected to the outer surface of the rotating shaft 307. The rear end of the eccentric linkage rod 308 is connected to the sliding groove 304 away from the side of the supporting groove 101. A separation frame 309 is installed between the two sliding grooves 304, and a screening net 310 is installed inside the separation frame 309.

[0052] As can be seen from the above, the crushed and separated cigarette butts and shredded tobacco fall onto the screening net 310 through the lower end of the crushing box 201, and the starting motor 306 drives the rotating shaft 307 to rotate, so that the eccentric linkage rod 308 drives the two sliding grooves 304 to slide inside the support frame 301. Since the two sliding grooves 304 are respectively provided with springs 305 and elastic members 303 on both sides, the elastic members 303 and springs 305 have elastic potential energy characteristics, so that the sliding grooves 304 drive the separation frame 309 to swing back and forth, thereby screening the shredded tobacco and cigarette butts on the screening net 310. The volume of the shredded tobacco is relatively small, and it falls into the storage mechanism 400 through the sieve holes of the screening net 310. The cigarette butts are relatively large in volume, so they will be left on the screening net 310, thereby completing the separation of the shredded tobacco and the cigarette butts, and the separation efficiency is relatively high. The separation effect of the cigarette butts and the shredded tobacco is better, which can reduce the mixing of the shredded tobacco and the cigarette butts, and then reduce the workload of subsequent manual screening, thereby improving the efficiency of the waste smoke treatment process.

[0053] Exemplarily, among the two sliding grooves 304 , one sliding groove 304 may be fixedly connected to the separation frame 309 , and the other sliding groove 304 may be slidably connected to the separation frame 309 .

[0054] Embodiment 4

[0055] The fourth embodiment of the present invention comprises a cleaning mechanism 500, which is installed on one side of the interior of the shaking assembly.

[0056] The cleaning mechanism 500 includes a threaded rod 501 rotatably connected to the inside of the separation frame 309, a transmission motor 502 is fixedly installed on one side of the separation frame 309, the output end of the transmission motor 502 passes through the separation frame 309 and is fixedly connected to the threaded rod 501, a threaded ring 503 is meshed on the outer surface of the threaded rod 501, and a movable plate 504 is fixedly installed on the outer surface of the threaded ring 503.

[0057] A cleaning brush 505 is fixedly installed on the front side of the movable plate 504 , and the cleaning brush 505 is in contact with the screening net 310 .

[0058] As can be seen from the above, when a large number of cigarette butts are accumulated on the screening net 310, the operation of the collecting mechanism 100, the crushing mechanism 200 and the separating mechanism 300 is stopped, and the transmission motor 502 is started to drive the threaded rod 501 to rotate. Since the threaded ring 503 is meshed with the threaded rod 501, the threaded ring 503 can drive the moving plate 504 to move horizontally inside the separation frame 309, and then drive the cleaning brush 505 to move on the screening net 310. On the one hand, the cleaning brush 505 can clean the cigarette butts for easy storage; on the other hand, the cleaning brush 505 moves on the screening net 310 to clean the tobacco shreds blocked in the sieve holes, so as to avoid the sieve holes being blocked and affecting the screening efficiency.

[0059] Embodiment 5

[0060] The fifth embodiment of the present invention comprises a storage mechanism 400 , and the storage mechanism 400 comprises a tobacco storage box 401 disposed between two support frames 301 .

[0061] The storage mechanism 400 also includes a suction fan 402 fixedly installed on the upper surface of the support frame 301. The feeding end of the suction fan 402 is fixedly connected to a pipe 403, the lower end of the pipe 403 is fixedly connected to a dust hood 404, the output end of the suction fan 402 is fixedly connected to a discharge pipe 405, and a cigarette butt storage box 406 is arranged below the output end of the discharge pipe 405.

[0062] As can be seen from the above, after the tobacco is screened by the screening net 310, it enters the tobacco storage box 401 for storage for subsequent processing. The cigarette butts are swept to the bottom of the dust hood 404 by the cleaning brush 505, and the suction fan 402 is started to adsorb the cigarette butts through the dust hood 404 and the pipe 403, and transported to the inside of the cigarette butt storage box 406 through the discharge pipe 405, thereby completing the separate storage of cigarette butts and tobacco, which is convenient for subsequent processing.
