Description

Technical Field

[0001] The utility model relates to the technical field of conveying for preparing dry powder coatings, and more specifically, to a spiral conveying mechanism for preparing dry powder coatings. Background Art

[0002] In the current technical environment, there are some obvious design limitations for the screw conveying mechanism used in the preparation of dry powder coatings. These problems mainly focus on the height adjustability of the conveying mechanism, the flexibility of the conveying length, and the ability to quickly disassemble and assemble components. These limitations may lead to inefficiency and adaptability problems in the changing industrial production environment, thereby affecting the continuity and efficiency of the overall production process.

[0003] First of all, most of the existing spiral conveyor mechanisms adopt a fixed height structure design, which means that the height of the discharge port cannot be adjusted. In the actual production line, different processing equipment and production layouts require the conveying mechanism to have a certain flexibility to adapt to different working heights. The fixed height design limits the versatility and flexibility of the mechanism, making the spiral conveyor mechanism unable to easily adapt to the changing production line requirements. It may require additional modifications or the use of other non-standard adaptation facilities, thereby increasing production costs and complexity.

[0004] Secondly, the conveying length of existing conveying mechanisms is usually fixed, and this design also limits its applicability. When materials need to be transported over long distances or the production line needs to be reconfigured in a space-constrained environment, fixed-length conveying mechanisms often cannot meet these requirements. The fixed conveying length not only reduces the adaptability of the equipment, but may also cause inconvenience in the production process, because any adjustment or expansion of the production line may require major modifications or replacements to the entire conveying system.

[0005] In addition, although there are some conveying mechanism designs on the market that can extend the conveying length, the connection and disconnection operations of the conveyor racks in these systems are often cumbersome, and the existing designs fail to provide a mechanism for rapid disassembly and assembly, which is particularly inconvenient when the conveying mechanism needs to be frequently adjusted or maintained. The complicated disassembly and assembly process not only consumes time, but also increases labor intensity, thereby affecting construction efficiency. In a fast-paced production environment, the ability to quickly disassemble and assemble is the key to improving production efficiency and flexibly responding to changes in production needs.

[0017] (III) Beneficial effects

[0018] Compared with the prior art, the utility model provides a spiral conveying mechanism for preparing dry powder coating, which has the following beneficial effects:

[0019] 1. The adjustment device makes the discharge port height of the conveying mechanism adjustable through the hydraulic system, which solves the problem of being unable to adapt to different production line heights and increases the flexibility and applicability of the mechanism. This height adjustment function is particularly critical because it allows a single device to work effectively in a variety of different production environments, reducing production delays and cost increases caused by mismatches.

[0020] 2. The splicing device achieves variability in conveying length through modular cylinder design. This design allows the cylinder length to be increased or decreased according to actual needs, thus overcoming the limitations of traditional fixed conveying length. The modular cylinder not only enables the equipment to adapt to production needs of different lengths, but also provides great convenience when adjusting or expanding the production line, making the adjustment work faster and more cost-effective. In addition, this splicing method also simplifies the expansion and maintenance of the production line, improves production efficiency and reduces maintenance costs.

Through the improved connection sleeve and guide groove design, the quick-connect device ensures the rapid connection and removal of the feed rod, significantly improving the efficiency of construction and maintenance. This is especially important in a production environment that requires frequent replacement or maintenance. It not only reduces machinery downtime, but also reduces labor intensity and safety risks.

The guide sleeve 8 slides along the side wall of the connecting sleeve 7 and compresses the push spring 13 connected on one side, and then the guide sleeve 8 drives the guide groove 9 to move.
