DETAILED DESCRIPTION

[0023] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0024] Embodiment 1

[0025] like Figure 1 As shown, this embodiment provides a built-in flavoring device for a cigarette making machine, wherein the flavoring device 2 is arranged below the tobacco hopper 1 of the cigarette making machine, and is used to add flavors to the tobacco entering the cigarette making machine.

[0026] In view of the problem that in the prior art, the added flavorings of tobacco will be lost to a certain extent during the storage and air conveying process, thereby affecting the sensory quality and style characteristics of the cigarettes, this embodiment proposes to build a flavoring device inside the cigarette making machine to add a flavoring process to the tobacco before rolling the cigarettes to ensure the sensory quality of the cigarettes.

[0027] Specifically, if Figure 2 As shown, the flavor replenishing device 2 includes a device housing and a tobacco inlet air lock assembly 6, a nozzle 10 and a tobacco outlet air lock assembly 12 arranged inside the device housing. The device housing is made of stainless steel, and the top and bottom of the device housing are open. The tobacco inlet air lock assembly 6 is arranged below the top opening of the device housing, and the tobacco outlet air lock assembly 12 is arranged above the bottom opening of the device housing. The position between the tobacco inlet air lock assembly 6 and the tobacco outlet air lock assembly 12 forms a flavor replenishing chamber. The nozzle 10 is arranged on the inner wall of the device housing, located between the tobacco inlet air lock assembly 6 and the tobacco outlet air lock assembly 12, that is, located in the flavor replenishing chamber, and the direction of the nozzle 10 is toward the inside of the device housing, and is used to spray flavors to the tobacco passing through the inside of the flavor replenishing device.

[0028] The nozzle 10 is a dual-medium nozzle, wherein the ejection medium of the nozzle is compressed air, and the dual-medium nozzle is connected to the flavor material tank and the compressed air supply part through pipelines respectively. When replenishing the flavor, the compressed air and the flavor are mixed in the nozzle and ejected. The number of nozzles is preferably 2, and the 2 nozzles are respectively arranged on both sides of the device housing.

[0029] like Figure 3-4 As shown, the tobacco inlet air lock assembly 6 includes a first axle 7, which is rotatably mounted in the device housing around its own axis. A plurality of first scrapers 8 are connected to the first axle 7, and the plurality of first scrapers 8 are arranged circumferentially along the first axle 7, and a feeding space is formed between two adjacent first scrapers. A motor 4 is also provided on the flavor replenishing device to provide power for the tobacco inlet air lock assembly 6. The first axle 7 is transmission-connected to the output end of the motor, and rotates under the action of the motor.

[0030] One end of each first scraper 8 is fixedly connected to the first wheel shaft 7, and the other end is connected to a rubber sleeve 15, and the rubber sleeve 15 contacts the inner wall of the device housing. The rubber sleeve 15 and the first scraper 8 are fastened by a screw 13, and the rubber sleeve 15 is in close contact with the inner wall of the device housing 14 and can rotate flexibly to avoid material leakage.

[0031] Similarly, the tobacco outlet air lock assembly 12 includes a second axle, which is rotatably connected in the device housing, and a plurality of second scrapers are connected to the second axle, and the plurality of second scrapers are arranged circumferentially along the second axle. The second axle is also driven by a motor and is in transmission connection with the motor. The tobacco outlet air lock assembly 12 has the same structure as the tobacco inlet air lock assembly 6, and will not be described in detail here.

[0032] In addition, the fragrance replenishing device is also provided with a first photodetector 5 and a second photodetector 9. The first photodetector 5 is arranged on the inner wall of the device housing, located on the upper part of the tobacco inlet air lock assembly 6, and is used to sense the tobacco entering the fragrance replenishing device. The second photodetector 9 is arranged on the inner wall of the device housing, and is located between the tobacco inlet air lock assembly 6 and the nozzle 10, and is used to sense the tobacco entering the fragrance replenishing chamber. The first photodetector 5 and the second photodetector 9 are connected to the control system and receive control of the control system. At the same time, the control system is also connected to structures such as motors to control the overall action of the fragrance replenishing device. When the first photodetector detects tobacco, the control system receives a sensing signal (such as a high-level signal), and at this time, the motor connected to the first axle and the second axle can be controlled to work, and the inlet and outlet air lock assemblies can be controlled to work; when the second photodetector detects tobacco, the control system receives a sensing signal, and at this time, the nozzles on both sides of the fragrance replenishing chamber can be controlled to work, and the incoming tobacco can be replenished with fragrance. In some embodiments, the flavoring flow rate can be further controlled, such as by providing a valve controlled by a control system on a pipeline connected to the nozzle to control the flow rate of compressed air and flavor, thereby controlling the flow rate.

[0033] In some embodiments, a moisture exhaust door switch 11 is also provided on one side of the fragrance replenishing chamber, and the moisture exhaust door switch is connected to the moisture exhaust air duct, and the moisture exhaust air duct is further connected to the exhaust gas duct (not shown in the figure). The moisture exhaust door switch is arranged on the inner wall of the device housing and is located between the tobacco inlet air lock assembly and the tobacco outlet air lock assembly. The moisture exhaust door switch is a manually rotatable switch. When the device needs to be cleaned, the moisture exhaust air duct is opened by hand, and the moisture exhaust air duct is closed during normal production.

[0034] Before normal production, according to the requirements of the production brand, prepare an appropriate amount of tobacco flavoring of the brand and place it in the flavoring material tank. At the same time, manually close the dehumidification damper switch and the corresponding negative pressure switch of the dehumidification air duct. When the cigarette machine is started, the upstream feeder supplies tobacco to the cigarette machine, and the tobacco enters the tobacco hopper, and the tobacco in the hopper is transported downward to the flavoring device. When the first photoelectric detector on both sides of the device entrance detects tobacco, the motor starts, and the first and second wheel shafts in the tobacco inlet and outlet air lock components rotate. The first scraper transports the falling tobacco to the flavoring chamber. After the second photoelectric detector detects the tobacco, the dual-medium nozzle acts to add flavor. The flavor is sprayed into the flavoring chamber under the irradiation of compressed air and fully contacts with the falling tobacco. The operator can also control the flavoring flow rate through the control system according to the process standards. The tobacco that has been flavored falls into the tobacco outlet air lock component. Under the action of the second scraper, the tobacco is transported to the pre-supply device 3 of the cigarette machine and enters the subsequent production process. This process is used to add flavor to the tobacco in the cigarette making machine.

[0035] When the cigarette machine needs to produce different brands of cigarettes or needs maintenance, the aroma replenishing device can be cleaned. First, clean the flavor material tank with alcohol. After cleaning, add an appropriate amount of alcohol, manually open the dehumidification air duct, and control the dual-media nozzle to spray alcohol on the aroma replenishing device. The residual flavor in the device is removed by spraying alcohol. After the alcohol is sprayed, compressed air is sprayed to further remove the residual odor. The waste gas in the cleaning process is discharged through the dehumidification air duct. After a certain period of spraying alcohol and compressed air, the aroma replenishing device is cleaned.
