Description

Technical Field

[0001] This utility model belongs to the field of cigarette production technology, specifically relating to a flavoring and fragrance metering device for cigarette filter rods. Background Technology

[0002] Cigarette filters are a common component of cigarettes, primarily used to filter harmful substances in smoke, providing a degree of cleanliness. They are typically made of high-density paper, cotton, or other filter materials, effectively reducing certain harmful components in tobacco smoke. Some cigarette filters are also designed with flavorings and fragrances on their surface, releasing specific aromas while filtering, allowing smokers to experience a richer flavor. Spraying these flavorings and fragrances onto the surface of cigarette filters requires the use of a spraying device.

[0003] However, existing spray devices cannot precisely control the release of flavorings and fragrances during operation, which can easily lead to either excessive or insufficient release. An overly strong aroma may cause discomfort or an unpleasant odor for smokers, while an insufficient aroma may make the tobacco taste too monotonous and lose its function of enhancing aroma. Therefore, uneven aroma release can lead to an unstable taste experience for smokers, which can affect their brand loyalty and overall satisfaction. Utility Model Content

[0004] The purpose of this invention is to provide a flavoring and fragrance metering spraying device for cigarette filter rods, which can meter-spray flavoring and fragrance onto the surface of cigarette filter rods, thereby improving the reliability and consistency of the product.

[0005] The specific technical solution adopted by this utility model is as follows: A flavoring and fragrance metering device for cigarette filter rods includes a liquid storage tank, a support frame, and a filter rod storage box. The support frame is fixedly installed on the top of the liquid storage tank, and the filter rod storage box is installed on the top of the support frame. A metering mechanism is provided on the top of the support frame. The metering mechanism includes a cylinder, a ball, a pad, a liquid extraction port, a compression spring, a pressure plate, a liquid outlet, a tube, a movable ball, a metering pipe, and a metering head. The cylinder is fixedly installed on the inner wall of the support frame, the ball is movably disposed at the bottom of the inner wall of the cylinder, and the pad is fixedly installed on the inner wall of the cylinder and located above the ball. The liquid extraction... An outlet is located at the top of a pad. One end of a compression spring is fixedly connected to the top of the pad. A pressure plate is fixedly connected to the other end of the compression spring. The pressure plate is slidably connected to the inner wall of a cylinder. An outlet is located at the top of the pressure plate. A tube is connected to the top of the pressure plate and is movably disposed inside the cylinder. A movable ball is disposed inside the tube and located at the top of the pressure plate. The movable ball is disposed on the inner wall of the outlet. One end of a spray pipe is connected to the top of the tube, and the other end of the spray pipe extends to the outside of the cylinder. A spray head is connected to one end of the spray pipe.

[0006] Preferably, the top of the support frame is provided with a quantitative output mechanism, which includes a mounting frame, a pressing head, a servo motor and an extrusion component. The mounting frame is fixedly installed on the top of the support frame, the pressing head is fixedly installed on the top of the injection pipe, the servo motor is fixedly installed on the top of the mounting frame, the output shaft of the servo motor passes through the inner side of the mounting frame, and the extrusion component is fixedly connected to the output end at the bottom of the servo motor.

[0007] Preferably, the top of the pressing head is sloped, the extrusion member is arc-shaped, and the extrusion member is used in conjunction with the pressing head.

[0008] Preferably, the pressure plate is made of rubber, and the diameter of the pressure plate is adapted to the cylinder.

[0009] Preferably, a dust cover is installed on the top of the inner wall of the liquid storage tank, and a liquid filling pipe is connected to the top of the dust cover.

[0010] Preferably, an observation window is provided on one side of the liquid storage tank, and a scale line is provided on one side of the observation window.

[0011] Preferably, the bottom of the cylinder is connected to a pipe, and the other end of the pipe is located inside the liquid storage tank.

[0012] The technical effects achieved by this utility model are as follows: In this invention, when spraying flavoring liquid onto the surface of the filter rod, a servo motor can be activated first. The servo motor drives the extruder to rotate, which in turn engages with the pressing head and presses it downwards. The pressing head, under pressure, moves the spray pipe and tube body downwards inside the cylinder. Simultaneously, the tube body moves downwards, causing the pressure plate to move down and compress the compression spring. This forces the gas inside the cylinder to exit through the outlet, tube body, and spray pipe. Simultaneously, the gas is expelled, lifting the movable ball upwards and separating it from the outlet, creating a vacuum inside the cylinder. When the extruder releases its pressure on the pressing head, the rebound force of the compression spring pushes the pressure plate, tube body, and spray pipe upwards again, causing the movable ball to move upwards under its own weight. When the outlet is blocked, the negative pressure inside the cylinder increases, allowing the ball to be lifted upwards through the suction port. Simultaneously, the flavoring liquid from the storage tank is forced into the cylinder cavity through the connecting pipe. When the extruder presses the pressing head again, the above steps are repeated, allowing the flavoring liquid inside the cylinder to be sprayed out from the outlet, the tube, and the spray pipe. Finally, the flavoring liquid is sprayed onto the surface of one side of the filter rod through the spray head. By rotating the extruder and using an extruder at a fixed height, the force of each press on the pressing head is the same, thus controlling the amount of flavoring liquid sprayed to be consistent. This ensures that the amount of flavoring liquid sprayed on each filter rod is consistent, avoiding too much or too little flavoring, and ensuring the stability and consistency of the aroma.

[0015] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0016] like Figures 1-4As shown, a flavoring and fragrance metering injection device for cigarette filter rods includes a liquid storage tank 1, a support frame 101, and a filter rod storage box 102. The support frame 101 is fixedly installed on the top of the liquid storage tank 1, and the filter rod storage box 102 is installed on the top of the support frame 101. An injection mechanism is provided on the top of the support frame 101. The injection mechanism includes a cylinder 201, a ball 202, a pad 203, a liquid extraction port 204, a compression spring 205, a pressure plate 206, a liquid outlet 207, a tube 208, a movable ball 209, an injection pipe 210, and an injection head 211. The cylinder 201 is fixedly installed on the inner wall of the support frame 101, and the ball 202 is movably disposed on the cylinder. At the bottom of the inner wall of cylinder 201, a pad 203 is fixedly installed on the inner wall of cylinder 201 and located at the top of ball 202. A liquid extraction port 204 is opened at the top of the pad 203. One end of a compression spring 205 is fixedly connected to the top of the pad 203. A pressure plate 206 is fixedly connected to the other end of the compression spring 205 and slidably connected to the inner wall of cylinder 201. A liquid outlet 207 is opened at the top of the pressure plate 206. A tube body 208 is connected to the top of the pressure plate 206 and movably disposed inside cylinder 201. A movable ball 209 is disposed inside the tube body 208 and located at the top of the pressure plate 206. The movable ball 209 is... On the inner wall of the outlet 207, one end of the spray pipe 210 is connected to the top of the pipe body 208, and the other end of the spray pipe 210 extends to the outside of the cylinder 201. The spray head 211 is connected to one end of the spray pipe 210. A metering output mechanism is provided on the top of the support frame 101. The metering output mechanism includes a mounting frame 301, a pressing head 302, a servo motor 303, and a squeezing component 304. The mounting frame 301 is fixedly installed on the top of the support frame 101, the pressing head 302 is fixedly installed on the top of the spray pipe 210, and the servo motor 303 is fixedly installed on the top of the mounting frame 301. The output shaft of the servo motor 303 extends through the mounting frame 301. Inside the mounting bracket 301, the extrusion component 304 is fixedly connected to the output end of the servo motor 303. Through the cooperation of the quantitative output mechanism and the spraying mechanism, a consistent downward pressure can be provided under the drive of the servo motor 303. Through consistent extrusion motion, the amount of flavoring liquid sprayed each time is kept consistent, thereby achieving quantitative control and avoiding the situation of too much or too little flavoring, improving the stability of the aroma, and ensuring that the aroma concentration of each filter rod is consistent. In addition, the compression spring 205, the ball 202 and the movable ball 209 are all made of stainless steel, which has strong corrosion resistance and prevents rust from affecting normal operation.

[0017] like Figure 3 and Figure 4As shown, the top of the pressing head 302 is set as a slope, and the extruder 304 is arc-shaped. The extruder 304 is used in conjunction with the pressing head 302. The sloped design of the top of the pressing head 302 allows the extruder 304 to apply pressure evenly when it comes into contact with the pressing head 302. This design can avoid excessive local extrusion, thereby ensuring the uniform output of fragrance and flavor. At the same time, the cooperation between the sloped pressing head 302 and the arc-shaped extruder 304 makes the extrusion process smoother and avoids the impact caused by hard right-angle contact.

[0018] like Figure 2 As shown, the pressure plate 206 is made of rubber. The diameter of the pressure plate 206 is adapted to the cylinder 201. The rubber material has strong elasticity and can fit tightly against the inner wall of the cylinder 201 to ensure that there are no gaps during operation. The adapted diameter ensures that the pressure plate 206 can fully cover the opening of the cylinder 201, avoiding leakage or overflow of fragrance liquid.

[0019] like Figure 4 As shown, a dust cover 401 is installed on the top of the inner wall of the storage tank 1. The top of the dust cover 401 is connected to a liquid filling pipe 402. The main function of the dust cover 401 is to prevent external dust, debris, etc. from entering the storage tank 1, so as to avoid contaminating the fragrance and flavoring liquid inside the storage tank 1. Especially when storing chemicals, food, or other sensitive liquids, the entry of dust and debris will cause damage to the quality of the materials. This can maintain the purity of the liquid in the storage tank 1, reduce external pollution, and improve the safety and quality of the fragrance and flavoring liquid. The top of the dust cover 401 is connected to the liquid filling pipe 402, which allows the operator to easily add fragrance and flavoring liquid to the storage tank 1 through the liquid filling pipe 402 without removing the dust cover 401. This design can reduce the complexity of operation and improve convenience.

[0020] like Figure 1 and Figure 4 As shown, an observation window 501 is provided on one side of the storage tank 1, and a scale line 502 is provided on one side of the observation window 501. The observation window 501 and the scale line 502 allow the operator to easily observe the height or level change of the fragrance liquid in the storage tank 1, thereby judging the remaining amount of fragrance liquid. When the liquid level is close to the required position, the addition of liquid can be stopped in time to avoid over-addition.

[0021] like Figure 2 As shown, the bottom of the cylinder 201 is connected to a pipe 6, and the other end of the pipe 6 is located inside the storage tank 1. The design of the pipe 6 allows the fragrance liquid in the storage tank 1 to be drawn into the cylinder 201 through the bottom pipe 6, which simplifies the transfer process of the fragrance liquid and enables the fragrance liquid to be drawn quickly and safely from the bottom of the storage tank 1, avoiding the accumulation of fragrance liquid at the bottom of the storage tank 1.

[0022] The working principle of this utility model is as follows: When spraying flavoring liquid onto the surface of the filter rod, the servo motor 303 is first activated. The operation of the servo motor 303 drives the extruder 304 to rotate. The rotation of the extruder 304 cooperates with the pressing head 302 and presses the pressing head 302 downward. After being pressed, the pressing head 302 drives the spray pipe 210 and the pipe body 208 to move downward inside the cylinder 201. When the pipe body 208 moves downward, it drives the pressure plate 206 to move downward and presses the compression spring 205, causing the gas inside the cylinder 201 to be discharged through the liquid outlet 207, the pipe body 208 and the spray pipe 210. At the same time as venting, the movable ball 209 is pushed upward and separated from the liquid outlet 207, thus creating a vacuum inside the cylinder 201. When the extruder 304 releases its pressure on the pressing head 302, it can push the pressure plate 206, the pipe body 208 and the spray pipe 210 again under the rebound force of the compression spring 205. 10 moves upward, and the movable ball 209 blocks the liquid outlet 207 under its own weight, increasing the negative pressure inside the cylinder 201. This allows the ball 202 to be lifted upward through the liquid extraction port 204. At the same time, the flavoring liquid inside the storage tank 1 is forced into the cylinder 201 cavity through the connected pipe 6. When the extruder 304 squeezes the pressing head 302 again, the above steps are repeated, and the flavoring liquid inside the cylinder 201 is sprayed out from the liquid outlet 207, the tube 208, and the spray pipe 210. Finally, the flavoring liquid is sprayed onto the surface of the tobacco filter rod on one side through the spray head 211. Thus, by rotating the extruder 304 and under the action of the extruder 304 at a fixed height, the force of the extruder 304 pressing down on the pressing head 302 is the same each time, which can control the amount of flavoring liquid sprayed out to be consistent. This ensures that the amount of flavoring liquid sprayed on each tobacco filter rod is consistent, avoiding too much or too little flavoring, and ensuring the stability and consistency of the aroma.

[0023] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
