[0002] In tobacco redrying processing link, it is often needed to carry out node sampling to each key link to detect stem rate in strip tobacco leaf, leaf structure rate, broken piece rate and other key process indexes. At present, the sampling detection mode of most enterprises still adopts artificial quantitative sampling mode. Taking the cabinet outlet node sampling position of secondary hot air leaf conditioning machine buffer cabinet as an example, strip tobacco is stored in buffer cabinet after being processed by secondary hot air leaf conditioning machine, and is output to next stage by belt conveyor at buffer cabinet outlet. Since the net depth of secondary cabinet is 3 meters, belt conveyor needs to be elevated to more than 3 meters by stand to meet the requirement of cabinet outlet of secondary cabinet, to guarantee the authenticity of node sampling material, sampling personnel need to climb three-meter-high belt conveyor inlet position to complete node sampling work.

[0003] The node sampling method of threshing and redrying processing link contains 32 sampling nodes, four groups of sampling personnel are arranged for each node sampling, each group has 2 persons, and 8 persons complete node sampling work. Sampling time is arranged according to different tobacco incoming production batches for each node sampling, and the average sampling time is 1 hour / time, and the required manpower is great. In the sampling process, since multiple nodes are covered, sampling personnel need to climb stairs with special stainless steel alloy metal sampling box, the weight of each node sampling sample is 3000 (±300) g / batch, the weight of sampling carrying object is heavy, and the volume is large, sampling work is time-consuming and laborious, and the personal safety of sampling personnel is difficult to guarantee. In the sampling process, sampling weight may deviate from the standard due to the operation difference of sampling personnel, and at the same time, process indexes such as stem rate in leaf and leaf structure are greatly different, sometimes even need to be repeatedly sampled, causing waste of sampling manpower.

[0027] In view of the problem of serious waste of manpower for node sampling in the leaf threshing and redrying industry, and the problem of heavy climbing and high safety risk for sampling, some enterprises adopt the mode of manpower rotation sampling. As described above, in combination with the mode of continuous production for a long time, the mode of manpower rotation sampling cannot reduce the sampling work intensity, and the manpower is also wasted, and the situation of heavy climbing for sampling is not improved. The original sampling port at the end of the belt conveyor which needs to be climbed is additionally provided with an automatic sampling device, and the motor of the belt conveyor is transformed to have a forward and reverse rotation function, the belt conveyor is forward rotated in normal production, the belt conveyor is reverse rotated during sampling, and a timing setting is adopted, when the reverse rotation time makes the sampling weight reach the process standard, the reverse rotation is stopped and switched to the normal production mode. By using the reverse rotation mode, the conveyed material can be transported in the reverse direction, the material falling is controlled through the electric control flap of the material falling port, so that the function of quantitative automatic sampling is achieved.

[0028] The embodiment of the tobacco sheet automatic sampling device is provided, and specifically as shown in Figure 1 , which comprises a motor 2, a sampling port 3 and a material falling port 4; the motor 2 is installed at the head or tail of the belt conveyor 1 and drives the conveying belt to run through the driving roller; the sampling port 3 is located on the side of the belt conveyor 1 and corresponds to the material falling port 4, the material falling port 4 is located below the sampling port 3, the material falling port 4 is internally connected with an electric control flap 5, and the electric control flap 5 is located between the sampling port 3 and the material falling port 4; the motor 2 and the electric control flap 5 are electrically connected with a controller, and the forward rotation or reverse rotation of the motor 2 is controlled through the controller, so that the conveying belt is forward rotated or reverse rotated.

[0029] In the embodiment of the utility model, the material falling port 4 is made of corrosion-resistant alloy material.

[0030] In the embodiment of the utility model, the material falling port 4 is configured as a cylindrical seamless pipe, and the diameter of the cylindrical seamless pipe is 40 cm. The cylindrical seamless pipe has a circular cross section, which is beneficial to the smooth flow of the material in the pipe and reduces the possibility of material blockage. The selection of the pipe diameter should consider the flow and flow rate of the material to ensure that the material can pass smoothly and stably. The pipe wall of the seamless pipe has no welding seam, which makes the pipeline more structurally strong and can withstand higher pressure and impact. In addition, the material falling port 4 can also be configured as a seamless pipe of a square, as shown in Figure 2 .

[0031] In the embodiment of the utility model, the inner surface of the material falling port 4 is a smooth surface, and the smooth inner surface can reduce the friction and adhesion between the material and the material falling port, thereby reducing the adhesion of the material on the inner wall of the material falling port, helping the material to pass through the material falling port more smoothly, reducing the possibility of blockage and stagnation, and improving the production efficiency.

[0032] In the embodiment of the utility model, the horizontal placement of the belt conveyor 1, the non-perpendicularity between the material dropping port 4 and the horizontal plane of the belt conveyor 1.

[0033] In the embodiment of the utility model, the included angle between the material dropping port 4 and the horizontal plane of the belt conveyor 1 is 100°. The included angle structure leaves a buffer when the material drops, and prevents the material from accumulating on the inner wall of the material dropping port 4 due to an excessively large included angle.

[0034] In the embodiment of the utility model, as shown in Figure 3 The controller is in communication connection with the electronic screen, and the electronic screen is provided with a sampling button for triggering the automatic sampling process. The controller is in communication connection with the electronic screen through a data line or a wireless communication protocol (such as Bluetooth, Wi-Fi, etc.), so as to realize real-time transmission and interaction of information.

[0035] In the embodiment of the utility model, the controller is a PLC controller, and a timer is arranged in the controller to set the forward rotation time or the reverse rotation time of the motor 2. When sampling is needed, the sampling trolley is pushed to the position below the material dropping port, and the sampling control is manually clicked by the sampling personnel to submit the demand. When the sampling button on the electronic screen is pressed, the motor 2 is controlled to perform reverse motion to drive the belt conveyor to operate in reverse. The PLC controller sets the reverse rotation time delay of each time to be 2.6s through the timer. According to the fixed flow of the belt conveyor 6000KG / H, the single sampling dropping is about 4.3kg. The batch material quantity (about 4.3kg per batch) is dropped into the material dropping port 4 through the reverse operation of the belt conveyor. At this time, the electric control flap 5 in the material dropping port 4 is opened downward, and the running material passes through, so that the sampling trolley completes the batch sampling work through the standard dropping track of the material dropping port 4.

[0036] It should be noted that the use of the strip tobacco automatic sampling device is as follows: when sampling at the node in the shift, the sampling trolley is pushed to the position below the material dropping port 4 by the sampling personnel in advance. After the sampling personnel manually confirms that the sampling can be performed, the "sampling" button is clicked, and the material drops along the material dropping port to complete the node sampling work. When the unqualified products need to be returned to the warehouse in the daily shift, the automatic sampling port is used as the node. The sampling time delay can be modified by the operator to complete the dropping work of a large batch of materials, so as to isolate the unqualified products in time and prevent the unqualified products from flowing into the next process.

[0037] The automatic sampling device after leaf beating and redrying provided by the utility model can provide automatic sampling work for the material conveyed by the belt conveyor, is simple to add, does not damage the original machine structure, only needs to utilize the original sampling port of the belt conveyor, adds the material dropping port 4 with the electric control flap 5, controls the motor reverse rotation and sampling time setting through the PLC controller, and automatically reaches the sampling control function.
