Description

Technical Field

[0001] The utility model relates to the technical field of cigarette sugar and flavoring preparation equipment, in particular to a high-precision weight control device for preparing cigarette sugar and flavoring. Background Art

[0002] The raw ingredients for tobacco sugar and flavorings are stored in storage barrels. Different cigarette brands and flavors have unique recipes, requiring the use of these barrels for preparation. Given the high value, diverse specifications, and tobacco product monopoly nature of tobacco sugar and flavorings, weight errors often occur during their preparation due to residual raw materials dripping from the discharge port into the preparation container. Conventional weight control is often implemented within the discharge device, achieving precise control through high-precision opening and closing mechanisms at the pipe opening or through empirically adjusted early termination of the pumping mechanism.

[0003] There are several technical problems in conventional technology:

[0004] The high-precision opening and closing device of the pipe mouth often adopts a spring-type air-opening high-precision mechanical system. In order to prevent the mixing of raw materials during the preparation of tobacco sugar flavoring, independent pipeline feeding is often used. The spring-type air-opening high-precision mechanical system is highly dependent on imports and is expensive and difficult to maintain.

[0005] Adjusting the early end time of the pumping mechanism through experience is a common method of precision control. In the field of tobacco sugar flavoring preparation, due to the differences in fluidity and adhesion of sugar flavoring raw materials and the diversity of raw material types, it is difficult to accurately observe a universal early end time, and the precision control effect is difficult to meet the process parameter requirements.

[0006] In order to find a weight control solution that is both economical and high-precision, it is considered to move the weight control link from the discharge accuracy or discharge port to before the liquid enters the preparation container. Through the weight signal of the weighing system and the action signal of the discharge system, after the liquid reaches the preparation weight requirement, a device is designed that can automatically receive the residual liquid from the discharge port. When the prepared liquid reaches the preset weight, the discharge system stops discharging and reverses the material, and the receiving device quickly intervenes to intercept the residual liquid dripping from the discharge port.
