Description

Technical Field

[0001] The present application relates to the technical field of feeders in cigarette factories, and in particular to a drum cleaning device. Background Art

[0002] In the current production process of tobacco factories, there is a phenomenon of material adhering to the inner wall of the feeder. After long-term use, the feed end, inner wall and discharge end of the cylinder are affected by various factors, resulting in material residue in the cylinder. The details are as follows:

[0003] During the drum feeding process, when the material rotates with the drum, due to the high viscosity of the feed liquid itself, the material falls naturally under the influence of gravity, and the material fragments are suspended inside the drum under the influence of airflow. The smoke absorbs moisture and the aerosol solution of the feed liquid and adheres to the end plate of the feeding chamber, causing more and more smoke to adhere there.

[0004] On the inner wall of the cylinder, the rake nails arranged in a spiral or circular array are prone to material adhesion;

[0005] During the discharge process of the cylinder, the smoke foam contacts the discharge chamber and instantly adheres to the inner wall surface of the discharge chamber.

[0006] In summary, the above and more factors are likely to cause materials to remain in the drum. If the drum is not cleaned in time, it will affect the quality of subsequent production and processing materials and the quality of the final product.

[0007] In the prior art, for the maintenance and cleaning of the cylinder, the materials adhering to the inside of the cylinder need to be manually blown away. Since the inner wall of the cylinder is slippery and has many rake nails, there are great safety hazards. Utility Model Content

The main purpose of the injection is to increase the pressure of the tap water. The cleaning time is centrally controlled by the PLC. When the one-button cleaning is clicked, the sealing door set at the feed end of the drum will automatically open, and the equipment will move forward with the set time. When it enters the inside of the drum, the cleaning work will begin. The equipment can be set to a one-way cleaning mode: so it starts cleaning from the feed end, and after reaching the set position, the spray mode is turned on to blow away the remaining water stains in the cleaning pipeline. Then the equipment shrinks backward until it reaches the set position and stops. The reciprocating cleaning mode can also be set: so it automatically shrinks backward after the forward cleaning reaches the specified position. At this time, the control valve is not closed until the drum outlet position stops closing the water vapor and the compressed air is opened to blow the remaining water stains in the pipeline. The equipment automatically withdraws from the drum and closes the sealing door to complete the entire cleaning process.
