Description

Technical Field

[0001] The utility model belongs to the technical field of tobacco processing, and specifically relates to a tobacco fragrance spraying mechanism. Background Art

[0002] In the past, the silk-making and flavoring process was often used as the last step in the production of silk lines. This step is considered to be a key technology in cigarette making. It mainly involves spraying the spices evenly onto the finished tobacco to fully mix the tobacco material and spices, thereby improving the smell of the tobacco and enhancing the taste of the tobacco, thereby improving the quality of the tobacco.

[0003] For the flavoring process, the uniformity of the flavoring process of the same batch of tobacco and the consistency of the flavoring process of different batches of the same brand are the two most important indicators. Although the setting parameters of the system are determined during the tobacco flavoring process, the system parameters such as tobacco flow, air pressure, flavor viscosity, nozzle status, etc. will still change during the production process. Their changes will lead to the atomization effect of the flavor and the combination effect of the material curtain and the atomized flavor, thus affecting the production quality of tobacco.

[0004] In the traditional tobacco production process, in order to simplify the complexity of the equipment, the fragrance flow rate is followed by the tobacco mass flow rate to ensure that a certain ratio is maintained between the fragrance flow rate and the tobacco mass flow rate. However, nozzle parameters, such as the nozzle angle and the nozzle ejector position, are fixed after a single adjustment, and the nozzle is point-oriented. In actual production, these two parameters have a great influence on the fragrance atomization effect, and also affect the fusion effect between the atomized flavor and the tobacco material, thereby affecting the uniformity and consistency of tobacco fragrance and the quality of tobacco.

[0005] The utility model patent with announcement number CN204519338U was published on August 5, 2015. The name of the device is a flow guide device inside a tobacco flavoring drum. The device includes a drum body. The inner wall of the drum body is provided with more than one flow guide device distributed along the circumference of the drum body. An angle is set between each flow guide device and the axis of the drum body. The device has a simple structure and the uniformity of tobacco flavoring is limited. Utility Model Content

[0029] like Figures 1 to 7 As shown, the tobacco fragrance spraying mechanism comprises a support base 101, a roller support frame 102 is arranged on the support base 101, a roller 103 is arranged inside the roller support frame 102, and the roller 103 is connected to a driving device; a fragrance tank 401 is arranged on the side of the support base 101, and the fragrance tank 401 is connected to the nozzle 301; an end cover 104 is arranged at one end of the roller 103, a spray port 106 is arranged on the end cover 104, and a nozzle 301 is arranged on one side of the spray port 106, and the nozzle 301 is connected to a deflection mechanism. The two ends of the roller support frame 102 are square structures, which can ensure that the roller 103 is in a horizontal posture, and the middle part of the roller support frame 102 is a cylinder structure, which is used to stably support the roller 103, and the first bearing 205 is arranged at both ends of the roller 103, so that the first motor 201 can control the rotation of the roller 103 while the roller support frame 102 is fixed. The nozzle 301 sprays the flavoring agent into the drum 103 from the spray port 106. The second motor 306 drives the nozzle 301 to rotate and the first motor 201 drives the drum 103 to rotate so that the tobacco follows the rotation of the drum 103 and is fully mixed with the flavoring agent, thereby achieving the effect of improving the uniformity of tobacco flavoring.

[0030] like Figure 1As shown, the driving device includes a first motor 201, which is arranged at one end of the drum 103, and is connected to a first coupling 202, which is connected to a driving gear 203, and a driven gear 204 is arranged at the end of the drum 103, and the driving gear 203 is meshed with the driven gear 204; the drum 103 is arranged horizontally, and a first bearing 205 is arranged between the drum 103 and the drum support frame 102. The first motor 201 is a reduction motor, and the first motor 201 is fixed to the motor mounting seat 206 by bolts, and the motor mounting seat 206 and the support foot 111 of the support seat 101 are fixed to the ground, and the driven gear 204 is arranged on the outer surface of the drum 103, and the driving gear 203 and the driven gear 204 are meshed with each other, and the first motor 201 drives the drum 103 to rotate.

[0031] like Figure 3 As shown, the deflection mechanism includes an ejector pin 302, a first support plate 108 is provided on the end cover 104, a motor support seat 304 and a spring support column 305 are respectively provided at both ends of the first support plate 108, a second motor 306 is provided on the motor support seat 304, the second motor 306 is connected to a second coupling 307, the ejector pin 302 is connected to the second coupling 307, a thread 311 is provided in the middle of the ejector pin 302, an ejector pin support column 309 is provided on one side of the motor support seat 304, and the ejector pin 302 is threadedly connected to the ejector pin support column 309; the spring support column 305 is connected to a spring 303, a support panel 308 is provided above the first support plate 108, and both ends of the support panel 308 are respectively connected to the ejector pin 302 and the spring 303, the nozzle 301 is fixedly connected to the support panel 308, a support column 405 is connected to the bottom end of the nozzle 301, and a second bearing 310 is provided between the support column 405 and the first support plate 108. The above structure realizes the rotation of the nozzle 301 driven by the second motor 306. When the second motor 306 rotates forward, the ejector pin 302 pushes the support panel 308 in the forward state to realize the deflection of the nozzle 301. At this time, the spring 303 is in the extended state; when the second motor 306 rotates reversely, the support panel 308 loses its supporting force when the ejector pin 302 retreats. Under the tensile effect of the spring 303, the nozzle 301 deflects to the other side. Therefore, the second motor 306 can control the reciprocating deflection function of the nozzle 301. The motor support seat 304 is used to support and bolt the second motor 306. The second motor 306 is a small motor. The spring support column 305 provides a connection position for the spring 303. In order to prevent the rotation of the nozzle 301 from affecting the first support plate 108, a second bearing 310 is arranged between the two to realize the rotation of the nozzle 301 while ensuring the fixation of the first support plate 108. The thread 311 is distributed in the middle of the ejector pin 302, and the ejector pin 302 and the ejector pin support column 309 are connected by threads. The thread 311 of the ejector pin 302 is driven by the rotation of the motor to move forward. The angle deflection process of the nozzle 301 has a small movement amplitude and high stability.

[0032] like Figure 3 As shown, a second support plate 109 is provided below the first support plate 108, a pipe 402 is provided on the second support plate 109, a pipe fixing clamp 403 is provided on the pipe 402, the pipe 402 extends from the aroma tank 401 and is connected to the bottom end of the support column 405, and a hose 404 is provided at the top end of the pipe 402. The pipe fixing clamp 403 fixes the pipe 402 horizontally on the second support plate 109 to ensure the stability of the pipe 402, and the pipe 402 is connected to the spray head 301 through the hose 404 to adapt to the rotation of the spray head 301. The support column 405 plays the role of supporting the spray head 301, and a through hole is penetrated inside it to facilitate the connection between the pipe 402 and the spray head 301.

[0033] like Figure 3 and Figure 6 As shown, the support panel 308 is a square structure, and the support panel 308, the ejector pin 302 and the spring 303 are at the same height. Designing the support panel 308 to be square is conducive to establishing a mathematical model of the deflection parameters of the nozzle 301, thereby facilitating the design and adjustment to the required deflection parameters of the nozzle 301, so that it is suitable for different tobacco flavoring equipment; the support panel 308, the ejector pin 302 and the spring 303 are of the same height to ensure the stability of the installation of the nozzle 301.

[0034] like Figure 1 As shown, stirring gear shafts 105 are evenly distributed in the drum 103. The stirring gear shafts 105 evenly stir the tobacco in the drum 103 to improve the mixing degree of the tobacco and the spices.

[0035] like Figure 2 As shown, a camera observation port 107 is provided on one side of the injection port 106, and both the injection port 106 and the camera observation port 107 are circular structures. A feed port 112 is provided at the lower part of the end cover 104. The camera observation port 107 is used for the visual camera to observe the mixing of the tobacco shreds in the internal drum 103, and the machine vision technology is used to identify the fusion effect between the atomized flavor and the tobacco shreds in the flavoring drum 103, so as to adjust to a better position of the ejector pin 302 and the angle of the atomizing nozzle. Both the injection port 106 and the camera observation port 107 are circular structures to ensure that they will not block the nozzle 301 and the visual camera. The feed port 112 is a square structure and is used for feeding tobacco shreds.

[0036] like Figure 3 As shown, both ends of the bottom of the first support plate 108 and the second support plate 109 are provided with tripods 110. The tripods 110 are used to support the first support plate 108 and the second support plate 109 to ensure that they are in a horizontal state, thereby ensuring that the components installed thereon are in a stable position.

[0037] like Figure 5As shown, the two ends of the spring 303 are fixedly connected with spring fixing frames 313. The two ends of the spring 303 are fixed with spring fixing frames 313, and holes are punched on the support panel 308 and the spring support column 305 to weld and fix the spring 303 brackets at the two ends of the spring 303 in the holes.

[0038] like Figure 4 As shown, a limiting plate 312 is provided on the ejector pin 302 at one end of the thread 311. The limiting plate 312 can ensure that the ejector pin 302 will not fall out of the ejector pin support column 309.

[0039] The working process of the mechanism is as follows: tobacco material is fed from the feed port 112, the first motor 201 drives the drum 103 to rotate, the tobacco material rolls in the drum 103, the nozzle 301 sprays the fragrance of the fragrance tank 401 into the drum 103 from the spray port 106, and the ejector pin 302 is driven forward and backward by the forward and reverse rotation of the second motor 306. During the advance and retreat process of the ejector pin 302 and the stretching action of the spring 303, the reciprocating deflection of the angle of the nozzle 301 is realized, so that the fragrance is sprayed into the drum 103 from different angles and fully mixed with the tobacco material, so as to achieve the purpose of improving the uniformity of flavoring.

[0040] For the convenience of explanation, the following mathematical model is established:

[0041] See attached Figure 6 , the ABCD area in the figure is the initial state of the support panel 308, and the A'B'C'D' area in the figure is the state after the support panel 308 is deflected. When the ejector pin 302 is extended by L, the deflection angle of the ejector head 301 support panel 308 is r, that is, the deflection angle of the ejector head 301 is also r. Since the thread 311 is designed in the middle of the ejector pin 302, and its pitch is set to p, the number of turns driven by the second motor 306 to drive the ejector pin 302 to rotate is n, that is, L = p × n; the support panel 308 is set to be a square with a side length of a, so the angle between the two diagonals and the side length is 45°.

[0042] The extension L of the ejector pin 302, the deflection angle r of the nozzle 301, and the side length a of the support panel 308 satisfy the following formula after the following derivation:

[0043] ∠OAB=∠D′A′O=45°

[0044]

[0045] Let A′H=EH=x

[0046] ∠EHO=90°,∠EOH=r

[0047]

[0048]

[0049]

[0050]

[0051]

[0052]

[0053] L=AE·cos45°

[0054] After substituting and simplifying, we can get:

[0055]

[0056] According to the above formula, the required deflection angle of the nozzle 301 can be adjusted by determining the three parameters of the extension L of the ejector pin 302, the deflection angle r of the nozzle 301, and the side length a of the support panel 308, thereby achieving a better mixing uniformity of the tobacco and the flavoring.

[0057] The tobacco shredded aroma spraying mechanism is designed with a deflection mechanism controlled by a motor drive for the nozzle 301. The cooperation of the ejector pin 302 and the spring 303 is used to realize the reciprocating deflection function of the nozzle 301, solving the problem that the traditional nozzle 301 used in the existing tobacco shredded aroma spraying process cannot turn, and realizing the deflection function of the nozzle 301 in the aroma spraying process. The motor drives the nozzle 301 to rotate in combination with the rotation of the drum 103 so that the tobacco shredded material can be fully mixed with the spices, thereby improving the mixing uniformity of the tobacco shredded material and the spices, thereby improving the aroma spraying process quality and ensuring the quality of the processed product. The mechanism is reasonably designed, and the design parameters of the deflection mechanism are defined by a mathematical model, which can not only facilitate the adjustment of the deflection parameters, but also be adapted for application in different tobacco shredded aroma spraying equipment.

[0058] The above is an exemplary description of the utility model in conjunction with the accompanying drawings. Obviously, the specific implementation of the utility model is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the utility model; or the above concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
