Description

Technical Field

[0001] This utility model relates to the field of cigarette equipment technology, and in particular to a tobacco moisture balance device. Background Technology

[0002] In the development of cigarette products, tobacco leaves of different years, origins, and grades need to be used on the tobacco processing line. However, different raw materials have different hygroscopic properties. The moisture content of the raw materials directly affects their appearance quality, such as color, and physical properties, such as elasticity. It also affects the processing resistance and safety of the tobacco leaves, resulting in different processing conditions.

[0003] Currently, most manufacturers ignore the uneven moisture content of most materials when starting production and directly cut the bales for rehydration. When the moisture content of the tobacco leaves is too low, they are prone to breakage when cutting the bales, affecting the subsequent processing. When the moisture content of the tobacco leaves is too high, adding water a second time during rehydration can easily cause clumping, making them difficult to process.

[0004] Therefore, there is an urgent need to provide a tobacco moisture balancing device to solve the above problems. Utility Model Content

[0048] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0049] To automatically and quickly balance the moisture content of tobacco leaves based on the pre-production moisture content, this embodiment provides a tobacco leaf moisture balancing device, which is described below in conjunction with... Figure 1The specific content of this embodiment will be described in detail. It should be noted that the first direction mentioned in this embodiment is... Figure 1 The X direction in this embodiment, and the second direction mentioned in this embodiment are... Figure 1 in the Y direction.

[0050] like Figure 1 As shown, the tobacco moisture balancing device in this embodiment includes a first balancing chamber 1, a second balancing chamber 3, a conveying unit, and a microwave moisture meter 7. The first balancing chamber 1 is equipped with a micro-mist humidification unit 2, which regulates the humidity within the first balancing chamber 1. The second balancing chamber 3 is equipped with a hot air circulation unit 4, which regulates the temperature within the second balancing chamber 3. The conveying unit includes a moving mechanism 5 and a conveying mechanism 6. Materials can be placed on the conveying mechanism 6, which is mounted on the moving mechanism 5. The moving mechanism 5 can drive the conveying mechanism 6 into the first balancing chamber 1 or the second balancing chamber 3. The microwave moisture meter 7 is mounted on the conveying mechanism 6 and is used to detect the moisture content of the materials. The microwave moisture meter 7 measures the moisture content of materials by utilizing the principle that the propagation speed and intensity of microwaves change when they penetrate water-containing materials. When microwaves pass through water-containing materials, their propagation speed slows down and their intensity weakens. The microwave moisture meter 7 calculates the moisture content of the materials by detecting these two changes in physical properties after the microwaves pass through them.

[0051] In summary, the tobacco moisture balancing device provided in this embodiment uses a first balancing chamber 1 with a micro-mist humidification unit 2 to regulate internal humidity, thereby increasing the moisture content of the material. The second balancing chamber 3 uses a hot air circulation unit 4 to automatically heat and ventilate, thereby reducing the moisture content of the material. A microwave moisture meter 7 is used to detect the moisture content of the material on the conveying mechanism 6. Based on the different moisture contents of the materials, the moving mechanism 5 transports the materials to the first balancing chamber 1 for humidification or to the second balancing chamber 3 for drying, ensuring the moisture content of the materials is at a suitable level for subsequent processing.

[0052] Furthermore, the first balancing chamber 1 and the second balancing chamber 3 are arranged along a first direction, and the moving mechanism 5 includes a first moving module 51 and a second moving module 52. The conveying mechanism 6 is disposed on the first moving module 51, and the first moving module 51 is used to drive the conveying mechanism 6 to move along the first direction. The first moving module 51 is disposed on the second moving module 52, and the second moving module 52 is used to drive the first moving module 51 to move along a second direction. The first moving module 51 and the second moving module 52 can be, but are not limited to, a lead screw slide, a telescopic cylinder, or an electric actuator, etc., without further restrictions.

[0053] Furthermore, the conveying mechanism 6 includes a mounting frame 61, multiple rollers 62, and a conveyor belt. The mounting frame 61 is mounted on the first moving module 51, and the microwave moisture meter 7 is mounted on the mounting frame 61. The multiple rollers 62 are rotatably disposed within the mounting frame 61 and arranged at intervals along a second direction. The conveyor belt is wound around the multiple rollers 62, allowing materials to be placed on the conveyor belt. Using a conveyor belt to convey the tobacco flakes ensures smooth movement and prevents the tobacco flakes from scattering during movement.

[0054] Furthermore, the conveying mechanism 6 includes a drive motor, which is connected to one of the rollers 62 for transmission, and the drive motor drives the conveyor belt to move. Optionally, a reducer can be added between the drive motor and the corresponding roller 62 to increase the output torque.

[0055] Furthermore, a first temperature and humidity acquisition system 8 is installed in the first balance storage 1, and / or a second temperature and humidity acquisition system 9 is installed in the second balance storage 3. By adding the first temperature and humidity acquisition system 8, the temperature and humidity in the first balance storage 1 can be acquired; by adding the second temperature and humidity acquisition system 9, the temperature and humidity in the second balance storage 3 can be acquired. Materials before production are placed into the balance storage silos, which are equipped with temperature and humidity acquisition systems. A microwave moisture meter 7 can measure the moisture content of the materials before production to determine the amount of water required for balance.

[0056] Optionally, in some application scenarios, different temperature and humidity zones can be set up in the first balancing tank 1 and the second balancing tank 3, so that the material can be placed in different zones to carry out multi-mode moisture balancing according to its moisture content.

[0057] Furthermore, the micro-mist humidification unit 2 includes a water storage tank 21, a pump body 22, and a humidification pipe 23. The water inlet of the pump body 22 is connected to the water storage tank 21; one end of the humidification pipe 23 is connected to the first balance tank 1, and the other end of the humidification pipe 23 is connected to the water outlet of the pump body 22. By adding the pump body 22, water in the water storage tank 21 can be quickly transported to the humidification pipe 23, improving humidification efficiency. An ultrasonic humidifier is installed on the humidification pipe 23, which uses the principle of high-frequency oscillation to atomize water into ultrafine particles of 1-5 micrometers and disperse them into the air. This type of humidifier has high humidification intensity, high efficiency, and low energy consumption.

[0058] Furthermore, the micro-mist humidification unit 2 also includes a spray pipe 24 with multiple nozzles 241, and the humidification pipe 23 is connected to the spray pipe 24. Spraying water mist through multiple nozzles 241 not only increases the effective humidification area, but also helps to improve the uniformity of humidification of the tobacco.

[0059] Optionally, the micro-mist humidification unit 2 includes a return pipe 25, one end of which is connected to the water inlet of the pump body 22, and the other end of which is connected to the water storage tank 21. By adding the return pipe 25, excess water can be returned to the water storage tank 21, thus relieving pressure.

[0060] Furthermore, the hot air circulation unit 4 includes a circulation pipe 41 and a heater 42. The air inlet and outlet of the circulation pipe 41 are both connected to the second balance chamber 3, and the heater 42 is located at the air outlet of the circulation pipe 41. The air entering the circulation pipe 41 is heated by the heater 42, and the high-temperature gas then enters the second balance chamber 3 to increase the temperature of the tobacco, which helps to evaporate the moisture in the tobacco and reduce its moisture content.

[0061] Furthermore, the hot air circulation unit 4 also includes a fan 43, which is located at the air inlet end of the circulation pipe 41. By adding the fan 43, the air circulation speed can be accelerated, which helps to improve the heating efficiency of the hot air circulation unit 4 for the smoke.

[0062] In summary, the working principle of the tobacco leaf moisture balancing device in this embodiment is as follows: The first balancing chamber 1 is equipped with a micro-mist humidification unit 2, which can automatically spray water into the chamber area and automatically adjust the spray volume. The second balancing chamber 3 is equipped with a hot air circulation unit 4, which can automatically heat up and ventilate to treat moisture loss. Before production, the material is placed on a conveyor belt and its moisture content is first detected by a microwave moisture meter 7. When the moisture content is low, it is placed in the first balancing chamber 1. Based on the tobacco leaf moisture detection results and the pre-production time requirements, water is automatically sprayed to humidify the tobacco leaves. When the material moisture content is too high, it is transported to the second balancing chamber 3, where, based on the pre-production time requirements, heating and ventilation circulation are performed to reduce the moisture content of the material to a suitable level for subsequent processing.

[0063] Raw material moisture content varies depending on storage conditions, year, season, and storage location. The moisture content directly affects the processing resistance of tobacco leaves, leading to different processing requirements. This invention, based on the characteristics of tobacco raw materials, enables multi-mode tobacco moisture balance treatment to meet the needs of different materials, achieving rapid and balanced moisture content, facilitating subsequent production and processing, and ultimately improving cigarette quality.
