Description

Technical Field

[0001] The utility model relates to the technical field of tobacco shred-making auxiliary equipment, in particular to a dual-medium nozzle regulating device. Background Art

[0002] In the process of tobacco shreds, it is necessary to atomize the prepared sugar, flavors and other viscous liquids with high pressure compressed air or steam and apply them to the corresponding tobacco leaves and shredded tobacco. Adding tobacco leaves can improve the sensory quality and physical properties of tobacco leaves, and adding flavors to shredded tobacco can supplement, set off or improve the aroma of tobacco. The above liquids are transported to the dual-medium nozzle through pipelines and valves, and then steam or compressed air is used to spray the flavors and sugars evenly in proportion to the tobacco materials at a certain angle.

[0003] Since flavors and sugars are mixed and dissolved substances, they have certain particle size and viscosity. When they are ejected through a dual-medium nozzle under high temperature and high pressure for a long time, it is easy to cause a small amount of material to carbonize and adsorb on the inner wall of the nozzle, thus causing the nozzle to be blocked. In order to completely unclog the nozzle, it must be disassembled and cleaned. This process will destroy the original injection angle of the dual-medium nozzle, so that the injection angle needs to be repeatedly adjusted when the nozzle is reset after cleaning. It is not only time-consuming and laborious, but the accuracy of the angle adjustment cannot meet expectations, which affects the effect of flavoring and adding.

[0004] Therefore, it is necessary to provide a dual-medium nozzle adjustment device so that the dual-medium nozzle can easily adjust the spray angle after replacement or resetting, so as to achieve free selection and precise control of the spray angle, so as to ensure that the material is mixed and contacted with the flavor and sugar material to the maximum extent at an appropriate angle in the cylinder, thereby meeting the process quality requirements of flavoring and adding materials.

[0008] The pitch adjustment bracket includes a circular ring and a rectangular block for fixing the dual-medium nozzle. The circular ring and the rectangular block are vertically arranged. Two second through holes are opened on the rectangular block. The center distance between the two second through holes is equal to the concentric spacing between the waist-shaped groove and the first through hole. The rectangular block is threadedly connected to the fan-shaped block, and the rectangular block is arranged between the two fan-shaped blocks.

[0009] Furthermore, the axial center line of the second through hole on the rectangular block away from the circular ring is used as the rotation axis to drive the pitch adjustment bracket to swing along the waist-shaped groove on the fan-shaped block to adjust the pitch angle of the dual-medium nozzle.

[0010] Furthermore, a first angle scale line for measuring the left and right angles of the dual-medium nozzle is provided on the end surface of the first cylinder.
