Description

Background technique

In the production process of tobacco silk making lines, electronic belt scales are mainly used to measure material weight and control material flow. Material flow is a key factor affecting production quality. The tobacco silk making line process includes humidification, warming, adding sugar (flavor), and drying. Processes such as moisture and fiber blending have extremely high requirements on material flow, and the flow needs to be controlled by an electronic belt scale. The control of flow by the electronic belt scale directly affects the stability of product production. The current flow control principle of electronic belt scales is: when the material passes through the weighing area, the weight sensor under the metering roller will collect the instantaneous weight of the material in the weighing area at this time, and then calculate it through the PLC, and then adjust the motor frequency to change Belt speed to control the instantaneous flow of material. However, the current feeding method causes the instantaneous weight of materials in the weighing area to often fluctuate between large and small during production. The belt scale needs to adjust the belt speed in a wide range to control the flow, resulting in the belt speed being adjusted upwards and downwards. During the process, the flow rate fluctuates greatly, which affects the processing accuracy of the next step. Therefore, it is necessary to make improvements to address the above problems.

The instantaneous flow rate of the cut tobacco on the flow regulating conveying device 2 is fine-tuned by adjusting the conveying speed of the cut tobacco on the secondary flow regulating conveying device 2 according to the instantaneous weight of the cut tobacco detected by the secondary load sensor 2-1; in the above structure, the upper and lower distribution and the head and tail are used. The corresponding double scale structure uses the primary flow adjustment conveying equipment and the secondary flow adjustment conveying equipment to achieve precise control of the instantaneous weight of materials in the weighing area and avoids the large-range adjustment of the belt speed of the existing weighing scale platform. Disadvantages: Reduce flow fluctuations, thereby solving the problem of sudden large and small flow rates, stabilizing the incoming material flow rate, and reducing the time for belt speed adjustment on the weighing scale platform;

Among them, the conveying speed adjustment of the primary flow adjustment conveying equipment 1 and the secondary flow regulating conveying equipment 2 is adjusted based on the detection results of the speed sensor: the primary motor 1 in the primary flow regulating conveying equipment 1 - 2 is provided with a primary speed sensor for detecting the instantaneous rotation speed of the primary motor 1-2; specifically, the secondary motor 2-2 in the secondary flow regulating conveying equipment 2 is provided with a primary speed sensor for detecting the instantaneous rotation speed of the secondary motor 2-2.
