[0001] The utility model relates to the technical field of tobacco processing, in particular to a binless cut tobacco processing system. Background Art

[0002] In the blending process of the cigarette making workshop, cut stem, expanded cut tobacco, pneumatic cut tobacco, recycled cut tobacco, etc. are accurately and evenly blended into the main cut tobacco according to the product formula requirements. During the whole process, the flow control of the blending scale is regulated by the flow delay of the main cut tobacco scale. Therefore, the material flow stability of the main cut tobacco scale plays a key role in the accuracy and reliability of the blending process. According to the requirements of the latest version of the cigarette process specification: when the proportional blending method is adopted, the main cut tobacco flow should be uniform and stable, and the flow coefficient of variation should not be greater than 0.15%.

[0003] In the existing cut tobacco processing system in the cigarette making workshop, the average value of the flow coefficient of variation of the main cut tobacco scale is relatively large, the average value of the flow fluctuation is relatively large, and the flow peak value and the low value are relatively large, all exceeding the standard by several times, which has a greater impact on the stability of the blending process.

[0004] Therefore, there is an urgent need for a binless cut tobacco processing system to solve the above problems. Content of the Utility Model

[0009] An adding flavor machine, the adding flavor machine is connected to the discharge end of the buffer metering device;

[0010] An inverter, the inverter is communicatively connected to the conveyor belt, and the inverter is used for controlling the conveying speed of the conveyor belt.

[0011] According to the binless cut tobacco processing system provided by the utility model, a detection device for detecting the amount of cut tobacco is arranged in the buffer metering device, and the detection device is communicatively connected to the inverter.

[0014] According to the non-bin tobacco processing system provided by the present utility model, it further includes a control unit. The buffer metering device, the weighing and conveying device, and the frequency converter are all communicatively connected to the control unit.

[0015] According to the non-bin tobacco processing system provided by the present utility model, the weighing and conveying device is an electronic belt scale.

[0016] According to the non-bin tobacco processing system provided by the present utility model, the buffer metering device is a metering pipe.

[0017] According to the non-bin tobacco processing system provided by the present utility model, the feeding unit includes multiple conveyor belts.

[0031] The following will be combined with Figure 1 to describe the non-bin tobacco processing system provided by the present utility model.

[0032] Refer to Figure 1 As shown, the non-bin tobacco processing system provided by the embodiments of the present utility model includes a feeding unit 1, a buffer metering device 2, a flavoring machine 3 and a frequency converter 4. Among them, the feeding unit 1 includes a conveyor belt; the buffer metering device 2 is connected to the discharge end of the conveyor belt, and the buffer metering device 2 is used to buffer the incoming tobacco and control the tobacco flow rate; the flavoring machine 3 is connected to the discharge end of the buffer metering device 2; the frequency converter 4 is communicatively connected to the conveyor belt, and the frequency converter 4 is used to control the conveying speed of the conveyor belt.

[0033] The tobacco processing system without a bin provided by the utility model replaces the feeding bin in the traditional processing system with a feeding unit 1. The running speed of the conveyor belt in the feeding unit 1 is controlled by a frequency converter 4. When the incoming material remains unchanged, the material thickness is basically inversely proportional to the running speed of the conveyor belt. When the running speed of the conveyor belt decreases, the material thickness on the conveyor belt increases, and the weight of the tobacco on the entire conveyor belt increases; conversely, when the running speed of the conveyor belt increases, the material thickness on the conveyor belt decreases, and the weight of the tobacco on the entire conveyor belt decreases. Therefore, the belt conveyor can be regarded as a feeder with a certain tobacco storage capacity. By adjusting the motor frequency of the belt conveyor, the tobacco flow rate at the outlet of the belt conveyor can be adjusted, which can prevent the coefficient of variation of the main cut tobacco flow rate from exceeding the set value and improve the processing efficiency and flexibility.

[0034] Specifically, in this embodiment, the conveyor belt is controlled by a motor. The frequency converter 4 is communicatively connected to the motor of the conveyor belt, and the running speed of the conveyor belt can be adjusted by controlling the rotation speed of the motor through the frequency converter 4.

[0035] To improve the material storage capacity of the conveyor belt, in some embodiments, vertical baffle plates can be provided at both ends of the conveyor belt. The baffle plate can include a fixed plate and at least one stage of telescopic plates. The fixed plate is fixedly provided on both sides of the conveyor belt, and the telescopic plate is slidably fitted to the fixed part. The height of the baffle plate can be adjusted by sliding the telescopic plate, thereby adjusting the material storage capacity of the conveyor belt.

[0036] It should be noted that the flavoring machine 3 is used to evenly spray or add flavorings to tobacco to improve the taste, smell or other characteristics of the tobacco. The flavoring machine 3 includes a drum, a spraying system, a control system, and a flavoring supply system. The drum is used to hold the tobacco. The spraying system is used to convert the flavoring solution or flavoring powder into fine particles and evenly spray them on the surface of the tobacco. The spraying system can use compressed air, rotary nozzles or other spraying technologies to ensure that the flavorings are evenly covered on the surface of the tobacco. The control system is used to adjust parameters such as the spraying amount, spraying speed, and spraying mode of the spraying system to ensure the uniformity and consistency of the added flavorings. The control system can be adjusted according to production requirements to achieve an automated production process. The flavoring machine 3 is usually equipped with a flavoring supply system for supplying the flavoring solution or flavoring powder to the spraying system. The flavoring supply system can include equipment such as flavoring storage tanks, conveying pipelines, and pumps to ensure that the flavorings can be supplied to the spraying system in a timely and accurate manner.

[0037] According to some embodiments of the present utility model, a detection device for detecting the amount of cut tobacco is provided inside the buffer metering device 2, and the detection device is communicatively connected to the frequency converter 4. By providing the detection device inside the buffer metering device 2, it is possible to feedback-regulate the frequency converter 4 by detecting the amount of cut tobacco inside the buffer metering device 2, thereby further reducing the flow coefficient of variation of the main cut tobacco. For example, when there is less cut tobacco inside the buffer metering device 2, the conveyor belt can be controlled by the frequency converter 4 to increase the conveying speed, and when there is more cut tobacco inside the buffer metering device 2, the conveyor belt can be controlled by the frequency converter 4 to reduce the conveying speed.

[0038] See Figure 1 As shown, according to some embodiments of the present utility model, the cut tobacco processing system without a bin further includes a weighing conveyor 5. The weighing conveyor 5 is connected to the discharge end of the buffer metering device 2, and the discharge end of the weighing conveyor 5 is connected to the flavoring machine 3. By providing the weighing conveyor 5, it is possible to accurately measure the weight of the cut tobacco in real time, ensure the correct dosage is added in the flavoring machine 3, and thus ensure the quality and taste consistency of the product. In addition, the weighing conveyor 5 can monitor the conveying and weighing conditions of the cut tobacco in real time, promptly discover and solve any possible problems, and ensure the stability and continuity of the production process. Through precise metering control, the weighing conveyor 5 can reduce the waste of cut tobacco, avoid over-adding or under-adding caused by inaccurate metering, and thus reduce the production cost.

The discharge end of the weighing conveyor 5 is connected to the vibrating conveyor 6, and the discharge end of the vibrating conveyor 6 is connected to the flavoring machine 3. By providing the vibrating conveyor 6, it is possible to evenly lay the cut tobacco on the vibrating conveyor 6 through vibration, so as to evenly convey the cut tobacco to the next processing stage, ensure the even distribution of the cut tobacco in the flavoring machine 3, and thus improve the quality and consistency of the product.

In addition, the electronic belt scale has a simple structure, is easy to install, is applicable to different types of conveying systems, and has relatively low maintenance costs and a long service life.

[0042] According to some embodiments of the present utility model, the buffer metering device 2 is a metering tube. Using a metering tube for buffer metering of tobacco shreds can provide high metering accuracy, ensuring that the material flows at a relatively constant rate when passing through, thereby reducing metering errors. Secondly, the metering tube can provide stable flow and pressure conditions, enabling the metering device to maintain relatively stable metering performance under different working conditions, thus improving the stability and reliability of the system. In addition, the design of the metering tube is relatively flexible and can be adjusted and customized according to specific application requirements to adapt to the metering requirements of different materials, improving the applicability and flexibility of the system.
