Description

Technical Field

[0001] The utility model relates to a tobacco fermentation production line, in particular to a material humidification circulation control device for a tobacco fermentation line. Background Art

[0002] The cigarette fermentation production line is a production line that adds bacterial liquid or enzyme liquid to tobacco raw materials such as tobacco leaves, tobacco shreds or tobacco stems for fermentation. Before entering the fermentation line, the tobacco raw materials need to be humidified so that they can better blend with the bacterial liquid or enzyme liquid in the subsequent fermentation process.

[0003] In the tobacco production and manufacturing process, the production volume is huge, and there are special tobacco humidification processing equipment, such as the tobacco loosening and rehumidification unit, which has excellent humidification effect.

[0004] However, this type of equipment is often huge in size and overly dependent on system construction, making it difficult to apply to pilot and small-scale production lines designed in laboratories. Researchers cannot directly use the production lines to conduct experimental research, which makes some experiments based on production line transformation difficult to execute, and each step can only be disassembled and dispersed for separate processing.

[0005] In order to improve the humidification efficiency and detection efficiency of tobacco raw materials based on laboratory level, it is necessary to design a miniaturized automatic fermentation line and transform the feeding and humidification process of the fermentation line.

[0006] In order to solve the above problems, people have been seeking an ideal technical solution. Utility Model Content

[0007] The purpose of the utility model is to provide a humidification circulation control device for tobacco fermentation line material which can realize automatic detection and automatic adjustment, cyclic humidification and detection.

[0008] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a feeding humidification circulation control device on a tobacco fermentation line, comprising a feeding conveyor belt, a humidification component, a tobacco-specific moisture meter and a controller;

[0009] The humidifying assembly is arranged at the front half of the feeding conveyor belt, and cooperates with the feeding conveyor belt to form a semi-enclosed humidifying space, and humidifying units are distributed in the humidifying space;

[0010] The tobacco-specific moisture meter is arranged at the rear half of the feeding conveyor belt, and is used to detect the moisture content of the humidified tobacco raw materials on the feeding conveyor belt;

[0011] The controller is associated with the transmission motor of the tobacco-specific moisture meter, the humidification component and the feeding conveyor belt, controls the transmission motor to run slowly in the humidification link of the humidification component, and controls the transmission motor to run quickly in the measurement link of the tobacco-specific moisture meter.

[0012] Based on the above, the humidification unit includes an airflow inlet and an airflow outlet distributed in the humidification space, and the airflow inlet and the airflow outlet are externally connected to a high-temperature and high-humidity airflow circulation component.

[0013] Based on the above, the humidification unit includes a humidification nozzle, an air flow inlet and an air flow outlet distributed in the humidification space, and the air flow inlet and the air flow outlet are externally connected to a high-temperature and high-humidity air flow circulation component.

[0014] Based on the above, the humidification component includes an upper cover enclosing the front half of the feeding conveyor belt, the front end and the rear end of the upper cover are connected, and the upper cover and the feeding conveyor belt enclose the semi-enclosed humidification space.

[0015] Based on the above, the humidification component and the tobacco-specific moisture meter are respectively installed at the installation positions thereof with a through-beam sensor, the detection height of the through-beam sensor being lower than the loading height of the feeding conveyor belt, and the through-beam sensor being associated with a controller so as to pause the tobacco raw materials carried by the feeding conveyor belt at the humidification component and the tobacco-specific moisture meter.

[0016] Based on the above, the controller controls the transmission motor of the feeding conveyor belt to switch between low speed and high speed, and the ratio of the transmission motor speed during the humidification process of the humidification component to the transmission motor speed before and after detection by the tobacco-specific moisture meter is ≤1:5.

[0018] Based on the above, the external high-temperature and high-humidity air flow circulation component includes an air heater, a circulation pipeline, a circulation fan and a valve group.

[0019] Based on the above, the feeding conveyor belt is a slope feeding conveyor belt.

[0020] The utility model has substantial characteristics and progress compared with the prior art. Specifically, the utility model has the following advantages:

[0021] 1. The tobacco-specific moisture meter and humidification component are respectively set at the front and back half of the feeding conveyor belt. After humidification, it is transported to the back half for testing. If it passes the test, it will be sent to the next process. If it fails the test, the feeding conveyor belt will be controlled to return to the humidification component for humidification again. The process is repeated until the humidification parameters meet the standards, which solves the inconvenience of manual operation in traditional solutions.

[0022] 2. The humidification process and the detection process of the tobacco material are switched by alternating low and high speeds to ensure the high efficiency of the feeding conveyor belt. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The technical solution of the utility model is further described in detail below through specific implementation methods.

[0027] like Figure 1 and Figure 2 As shown, a tobacco fermentation line feed humidification cycle control device includes a feed conveyor belt 1, a humidification component 2, a tobacco-specific moisture meter 3 and a controller 4.

[0028] In the present embodiment, the feeding conveyor belt is an inclined feeding conveyor with an inlet end lower than the outlet end. The humidifying component 2 is arranged in the front half of the feeding conveyor belt 1, and cooperates with the feeding conveyor belt 1 to form a semi-closed humidifying space. The humidifying unit is distributed in the humidifying space. Specifically, the humidifying component 2 includes an upper cover enclosing the front half of the feeding conveyor belt, the front end and the rear end of the upper cover are connected, and the upper cover and the feeding conveyor belt enclose the semi-closed space. The humidifying unit includes an air flow inlet and an air flow outlet distributed in the humidifying space, and the air flow inlet and the air flow outlet are externally connected to a high-temperature and humidity air flow circulation component, and the external high-temperature and high-humidity air flow circulation component includes an air heater 5, a humidifier 6, a circulation pipeline 7, a circulation fan 8 and a valve group 9.

[0029] The tobacco-specific moisture meter 3 is arranged at the rear half of the feeding conveyor belt 1, and the tobacco-specific moisture meter 3 is used to detect the moisture content of the tobacco raw material on the feeding conveyor belt 1;

[0030] The controller 4 is respectively connected to the transmission motors of the tobacco-specific moisture meter 3, the humidification component 2 and the feeding conveyor belt 1, controls the transmission motor to run slowly in the humidification link of the humidification component, and controls the transmission motor to run quickly in the measurement link of the tobacco-specific moisture meter.

[0031] The external high-temperature and high-humidity air flow circulation component includes an air heater, a circulation pipeline, a circulation fan and a valve group, which are used to heat and humidify the circulating air.

[0032] In a preferred embodiment, in order to keep the conveyor belt running continuously, the controller controls the transmission motor of the feeding conveyor belt to switch between two speeds. In the humidification process, in order to ensure the humidification effect and the conveyor belt does not stop running, low-speed operation is adopted. When the tobacco-specific moisture meter 3 is needed to measure the humidification effect, high-speed operation is adopted. Specifically, the transmission motor adopts a servo motor, and the ratio of the transmission motor speed of the conveyor belt is set to ≤1:5, which can meet the needs.

[0033] In a preferred embodiment, in order to control the recognition accuracy, a through-beam sensor is installed at the installation position of the humidification component and the tobacco-specific moisture meter 3, respectively. The installation height of the through-beam sensor is lower than the loading height of the feeding conveyor belt. The through-beam sensor is associated with a controller so that the tobacco raw material carried by the feeding conveyor belt can be paused at the humidification component and the tobacco-specific moisture meter 3.

[0034] In other embodiments, the humidification unit includes a humidification nozzle, an air flow inlet and an air flow outlet distributed in the humidification space, and the air flow inlet and the air flow outlet are externally connected to a high-temperature air flow circulation component and three sets of temperature and humidity sensors.

[0035] Working principle description:

[0036] The front end of the feeding conveyor belt 1 is connected to a hopper. The feeding process is performed by manually putting raw materials into the hopper. The raw materials are spread out in the front half of the feeding conveyor belt and enter the action range of the humidification component 2. Then the feeding conveyor belt runs at a lower speed and enters the humidification stage.

[0037] During the low-speed humidification process, the feeding conveyor belt steadily takes away a certain amount of raw materials from the hopper. The time for the head material of the same batch of materials to pass through the humidification component 2 is controlled by the speed of the feeding conveyor belt 1. After reaching the set humidification time, it enters the detection stage.

[0038] In the detection stage, the feeding conveyor belt is switched to fast operation, and the humidified material is quickly transferred to the tobacco-specific moisture meter 3 for detection;

[0039] If the test is up to standard, it means that the humidification time set in the humidification link is reasonable. At this time, the feeding conveyor belt is controlled to return to the original position, and then humidification and feeding are carried out according to the originally set slow mode. The tobacco moisture meter 3 only needs to randomly check whether the humidification effect of subsequent tobacco materials in the same batch of materials meets the standard;

[0040] If the test fails to meet the standard, it means that the humidification time set in the humidification link is not enough. At this time, the feeding conveyor belt is controlled to return to the original position and humidification continues. The increased humidification time is superimposed on the original set time, and the test process is repeated until the test meets the standard. The accumulated total time is used as the humidification set time for subsequent tobacco materials in the same batch, and then it is operated in the manner that meets the test standard.

[0041] When the batch of tobacco raw materials is changed, the process needs to be restarted in order to configure the appropriate humidification time.

[0042] Under this solution, since the non-stop running speed of humidification is too low, the efficiency of the detection link is too low without speed change, so the acceleration and deceleration switching method is set to improve the efficiency of the entire humidification time adjustment.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the utility model can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the utility model, which should be included in the scope of the technical solution for protection of the utility model.
