Description

A flow regulating device for measuring tube of tobacco blending scale

technical field

The invention relates to the technical field of silk-making equipment in the tobacco industry, in particular to a flow regulating device for a measuring tube of a tobacco blending scale.

Background technique

The blending scale is mainly used in the tobacco silk production line. According to the material formula specified by the production grade and the set blending ratio, the weighing and blending work is completed through the joint action of the weighing sensor and the speed sensor. It can be used together with other equipments to convey the material flow in a constant, uniform and quantitative manner. The metering tube is a device used to control the flow of materials. It provides a constant flow of material input for the belt scale to ensure weighing and blending accuracy. It is mainly composed of a barrel, a steel frame, a hopper and a photoelectric tube. The side wall panel is made of transparent plexiglass plate, and two pairs of opposite photoelectric cells are installed on the photocell sliding rod to control the storage amount of materials in the tube. Output to other devices with stable layer width and layer thickness.

The upper wall panel of the discharge port of the metering tube is designed as a swing valve (valve door page), which can manually or automatically adjust the yaw angle of the swing valve and adjust the width of the material layer. The thickness of the layer to control the thickness of the material layer sent out. Due to the different blending ratios of materials of different grades, generally within the range of 10-60%, when changing the card during the production process, the operator needs to manually adjust the swing valve and sliding door to adjust the width and height of the discharge section to meet the requirements of the metering tube. The flow rate of the material is matched with the flow rate required by the mixing ratio. Because the adjustment amount of the swing valve and the sliding door ratio depends on the operator's personal experience, if the adjustment amount is too low, it will easily lead to insufficient mixing and feeding. The high thickness causes the output material to collapse into the next process, which affects the uniformity and accuracy of the blended material. Therefore, the operator needs to repeatedly adjust the flow rate of the metering tube to meet the requirements of the mixing ratio. The number of times is large, and the labor intensity of the operator is high. In addition, the existing automatic adjustment device has a complex structure and high cost, which is not conducive to comprehensive promotion and use.
