Description

Technical Field

[0001] This invention relates to the field of cleaning equipment, and more specifically to an automatic cleaning machine for powder conveying baskets. Background Technology

[0002] As is well known, dust accumulated in the material baskets during the batching process of automated equipment can have many negative impacts on production. For example, inaccurate formulation ratios can cause residual dust to alter the actual volume of the basket, leading to unstable material quantities and fluctuations in product quality. Cross-contamination can also occur; when the same basket is used to transport different materials, residual material from the previous batch can mix into the next, causing contamination. This is particularly critical in industries such as food, pharmaceuticals, and fine chemicals, potentially leading to the scrapping of an entire batch and resulting in significant economic losses. Furthermore, there are high safety hazards. Drifting dust can interfere with photoelectric sensors and precision components of weighing modules, causing batching errors or sudden equipment malfunctions. Additionally, flammable dust, when accumulated to a certain concentration, can potentially explode upon contact with static electricity or sparks. Toxic dust can also threaten the physical and mental health of operators. Currently, the main methods for cleaning material baskets remain manual cleaning and basic mechanical cleaning, i.e., daily, scheduled cleaning at fixed points, using brushes and scrapers to directly remove residual material inside the basket. However, neither method can effectively, promptly, and thoroughly eliminate the problem of dust residue accumulation. Summary of the Invention

[0003] In order to overcome the shortcomings of the prior art, the present invention provides an automatic cleaning machine for powder conveying baskets to prevent powder residue on the surface of the baskets from affecting the accuracy of the batching weight and the risk of mixing.

[0004] The technical solution adopted by this invention to solve its technical problem is as follows: an automatic cleaning machine for powder conveying baskets, equipped with a conveying track, characterized in that a cleaning cover for the basket is installed on the conveying track, and an inlet and outlet are sealed on the cleaning cover. An upper dust removal pipe and a lower dust removal pipe are provided on the outside of the cleaning cover and are connected to the inner cavity of the cleaning cover. The upper dust removal pipe and the lower dust removal pipe are connected to a dust collector box above. A dust collector filter bag is provided inside the dust collector box. An induced draft fan is connected to the top of the dust collector box through an induced draft pipe. A dust collector discharge port is provided at the bottom of the dust collector box. A rotating air blowing pipe is provided inside the cleaning cover. A rotating motor is installed on the top of the cleaning cover. The rotating motor can drive the rotating air blowing pipe to rotate. An air blowing nozzle is provided on the rotating air blowing pipe. The air blowing nozzle is driven by the rotating motor above the cleaning cover. An electromagnetic valve is installed on the air source main pipe and is connected to the rotating air blowing pipe.

[0005] The upper end of the rotary air blowing pipe is sealed to the main air source pipe via a mechanical seal.

[0006] The beneficial effects of this invention are that it can effectively remove dust residue in the material basket, avoid the inaccurate batching ratio caused by residual materials changing the actual volume of the material basket, and realize the automation of material basket cleaning.

[0010] In the figure, the present invention includes a conveying track 2, on which a material basket cleaning cover 3 is installed. The material basket cleaning cover 3 has a sealed inlet and outlet. An upper dust removal pipe 4 and a lower dust removal pipe 5, connected to the inner cavity of the material basket cleaning cover 3, are located on the outside of the cover. The upper dust removal pipe 4 and the lower dust removal pipe 5 are connected to a dust collector housing 13 above. The dust collector housing 13 contains dust filter bags 14 for filtering dust 12. An induced draft fan 17 is connected to the top of the dust collector housing 13 via an induced draft pipe 16. A dust collector discharge port 15 is located at the bottom of the dust collector housing 13 for discharging the collected dust. The cleaning hood 3 is equipped with a rotating air blowing pipe 6. A rotating motor 11 is installed above the material basket cleaning hood 3. The rotating motor 11 can drive the rotating air blowing pipe 6 to rotate. The rotating air blowing pipe 6 is equipped with an air blowing nozzle 7. The air blowing nozzle 7 is driven by the rotating motor 11 above the material basket cleaning hood 3 to perform rotating air blowing cleaning on the material basket. The upper end of the rotating air blowing pipe 6 is sealed and connected to the air source main pipe 8 through a mechanical seal 10. When the rotating motor 11 drives the rotating air blowing pipe 6, it plays a sealing role. An electromagnetic valve 9 is installed on the air source main pipe 8. Compressed air enters the pipeline from the air source main pipe 8 and is controlled by the electromagnetic valve 9.

[0011] After feeding, the powder basket 1 automatically enters the basket cleaning hood 3 via the conveyor track 2, and then automatically closes the inlet and outlet to form a sealed space. Once the powder basket 1 is fixed in place, the induced draft fan 17 of the dust collector housing 13 starts, and through the filtration of the dust collector filter bag 14, a negative pressure space is formed inside the basket cleaning hood 3. The rotating air pipe 6 installed inside the basket cleaning hood 3 rotates around the powder basket 1 via the rotating motor 11 above the basket cleaning hood 3. The control system opens the inlet solenoid valve 9, spraying high-pressure compressed air around the powder basket 1 through the air nozzle 7 for cleaning. All residual dust 12 is blown away, and the dust inside the basket cleaning hood 3 is collected from all directions through the upper dust collection pipe 4 and the lower dust collection pipe 5.

[0012] This invention automates and thoroughly cleans the dust and residual materials inside the material basket, effectively removing dust residue and preventing inaccurate batching ratios caused by residual materials altering the basket's actual volume. This ensures stable material additions each time, significantly improving batching accuracy and reducing product quality fluctuations. Simultaneously, it thoroughly removes residues from previous batches, eliminating cross-contamination between different materials. This is particularly suitable for industries with stringent hygiene requirements, such as food, pharmaceuticals, and fine chemicals, preventing the scrapping of entire batches due to mixed materials and reducing economic losses. Furthermore, this invention promptly removes scattered and accumulated dust from the material basket, reducing dust interference with precision components such as photoelectric sensors and weighing modules, lowering the risk of equipment malfunctions and batching errors. It also avoids the explosion hazards caused by the accumulation of flammable dust and the health threats posed by toxic dust to operators, significantly improving production safety. This invention replaces traditional manual and basic mechanical cleaning methods, solving the problems of low efficiency, incomplete results, and inability to remove dust residue in a timely manner. It realizes the automation and high efficiency of material basket cleaning, eliminating the need for manual cleaning at fixed times and locations, ensuring production continuity, and reducing labor costs.
