Description

Technical Field

[0001] This utility model relates to the field of industrial automation technology, and in particular to a conveying system for unified feeding of multiple sets of mixers. Background Technology

[0002] Metal surface pretreatment agents, as core materials for modifying metal surfaces and improving corrosion resistance, are experiencing continuous market demand growth. Currently, common metal surface pretreatment agents include magnesium alloy conversion coating agents, aluminum alloy trivalent chromium passivating agents, chromium-free passivating agents, ceramic silane agent series agents, high-efficiency cleaning agents, phosphorus-free and nitrogen-free degreasing agents, and phosphating agent series agents. These agents require specific production processes. Specifically, multiple raw materials are added to a mixing device according to a preset ratio, and after thorough mixing and reaction, a metal surface pretreatment agent meeting quality standards is formed. The agent is then filled into designated containers using filling equipment for storage, transportation, and sales.

[0003] With the increasing market demand for metal surface pretreatment agents and the urgent pursuit of improved production efficiency by enterprises, automated production equipment is being used more and more widely in this field. Among them, automated chemical filling equipment, with its advantage of enabling automated quantitative filling operations, effectively reduces manual intervention, lowers labor intensity, and significantly improves the efficiency of the agent filling process, making it the preferred equipment for most pharmaceutical manufacturers.

[0004] However, in actual production, the contradiction between increasing filling speed and the stirring efficiency of the mixing device has gradually become prominent. Because the raw materials for metal surface pretreatment agents require a certain amount of time to be stirred in the mixing device to ensure that all components are fully mixed and reacted completely to meet the specified product quality requirements, the stirring operation in existing production systems often takes a long time. When using automated quantitative filling equipment at a high rate, once the agent in the currently supplied mixing device is filled, subsequent filling operations must stop and wait for the next mixing device to complete the raw material mixing and supply the agent. This problem seriously affects the continuity of the entire production process, making it difficult to further improve production efficiency. Therefore, it is necessary to propose an improved technical solution to address the above problems. Utility Model Content

[0005] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the above problems.

Detailed Implementation

[0018] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] Please see Figure 1-5 In this embodiment of the present invention, a conveying system for unified feeding of multiple sets of mixers includes a lifting frame 10, on which multiple sets of mixing devices 20 and a feeding device 30 are installed. The mixing device 20 includes a mixing tank 21 fixed on the lifting frame 10 and extending to the lower part of the lifting frame 10, a cover 22 disposed on the mixing tank 21, a mixing power mechanism 23 mounted on the cover 22, and a first discharge connector 24 mounted on the lower end of the mixing tank 21. The feeding device 30 includes a feeding bucket assembly 31 mounted on the lifting frame 10, a feed connector 32 connected to one side of the feeding bucket assembly 31, and a second discharge connector 33 connected to the lower part of the feeding bucket assembly 31. The system also includes a water pump 40, the input end of which is connected to a feed pipe 41, and the water pump 40 is connected to the first discharge connector 24 of the multiple sets of mixing devices 20 through the feed pipe 41. The output end of the water pump 40 is connected to a discharge pipe 42, which is connected to the feed connector 32.

[0020] During operation, the number of mixing devices 20 required is first calculated based on the required material quantity. Then, the mixing of the raw materials for the metal surface pretreatment agent is completed by the set number of mixing devices 20. The mixing power mechanism 23 of each mixing device 20 drives the mixing components in the mixing tank 21 to operate, fully mixing the raw materials put into the mixing tank 21 to react into qualified agents. After the agent is mixed, the water pump 40 is started. Its input end is connected to the first discharge joint 24 of multiple sets of mixing devices 20 through the feed pipe 41. It can selectively extract any one or more sets of agents from the mixing tank 21 according to actual needs. Then, the water pump 40 transports the extracted agent to the feed joint 32 of the feeding device 30 through the discharge pipe 42 at the output end. Finally, the agent is stored in the feeding tank assembly 31. The feeding tank assembly 31 then continuously supplies materials to the subsequent filling equipment through the second discharge joint 33 at the bottom. The whole process does not require frequent switching of the feeding pipeline between the mixing tanks 21, realizing a continuous connection from mixing to feeding.

[0021] Therefore, this conveying system effectively solves the problem of short shutdowns when multiple mixing tanks 21 are alternately fed. By connecting the water pump 40 and the feed pipe 41 with the first discharge joint 24 of multiple mixing devices 20, the system can flexibly extract the reagents from different mixing tanks 21 and uniformly transport them to the feeding device 30. The feeding device 30 can store a certain amount of reagents and can play a transitional role when switching mixing tanks 21. There is no need to interrupt the feeding process when switching mixing tanks 21, which completely eliminates the downtime during the switching process and significantly improves the continuity and overall efficiency of metal surface pretreatment reagent production.

[0022] Please see Figure 5 The feeding hopper assembly 31 includes a water channel plate 311 fixedly mounted on the lifting frame 10, a bracket 312 fixedly mounted on the water channel plate 311, and a hopper body 313 mounted on the bracket 312. A feed inlet 32 ​​is located on the side of the hopper body 313, and a second discharge hopper 33 is located in front of the water channel plate 311. A connecting pipe 314, which connects to the water channel plate 311, is located at the lower end of the hopper body 313. The connecting pipe 314 and the second discharge hopper 33 are connected through the water channel plate 311. This ensures stable installation of the hopper body 313 and, with the help of the water channel plate 311, connects the connecting pipe 314 at the lower end of the hopper body 313 to the second discharge hopper 33, allowing the second discharge hopper 33 to extend from the side for easy connection to automatic chemical filling equipment. Multiple second discharge joints 33 are provided, and multiple first solenoid valves 315 acting on each second discharge joint 33 are provided on the water circuit board 311. This enables independent control of the feeding status of each second discharge joint 33. It can flexibly adjust the feeding start / stop and feeding amount according to the needs of different filling equipment to avoid waste of reagents. When a filling equipment is under maintenance or suspended, only the corresponding first solenoid valve 315 is closed, without affecting the normal feeding of other equipment, thus ensuring the stability and flexibility of the overall production process.

[0023] Please see Figure 1-2 The lifting frame 10 includes a base plate 11, support rods 12 evenly distributed at the lower end of the base plate 11, and railings 13 installed above the edge of the base plate 11. The mixing device 20 and the feeding device 30 are both installed on the base plate 11. The lifting frame 10 provides a stable installation foundation for the mixing device 20 and the feeding device 30 through the base plate 11. The evenly distributed support rods 12 at the lower end can provide stable support for the base plate 11 and raise the overall height of the equipment to facilitate operation below or space utilization. The railings 13 above the edge of the base plate 11 can effectively protect the equipment and the safety of the operators. The overall structure takes into account the stability of equipment installation, ease of operation and safety of use.

[0024] Please see Figure 4When the conveying system is set to manual control mode, a manual valve 25 is provided at the first discharge joint 24, the feed pipe 41 is a flexible hose, and a water pipe quick connector 43 is provided at one end of the feed pipe 41 that connects to the first discharge joint 24. The feed pipe 41 is detachably connected to the first discharge joint 24 through the water pipe quick connector 43. This design allows operators to precisely control the start / stop and feed rate of the corresponding mixing tank 21 to the feed pipe 41 via manual adjustment, without relying on automated control components. This adapts to the manual operation needs of small-batch production, equipment debugging, or automated system failures, improving the system's compatibility. Simultaneously, the feed pipe 41 is detachably connected to the first discharge connector 24 via a quick-connect water pipe 43. This simplifies the installation and disassembly process between the feed pipe 41 and the mixing device 20, facilitating subsequent individual inspection, replacement, or cleaning of the pipe, mixing tank 21, or water pump 40. Furthermore, it allows for flexible adjustment of the connection between the feed pipe 41 and different mixing devices 20 according to actual production needs, enhancing the system's ease of operation and adaptability in manual control mode.

[0025] Please see Figure 3 When the conveying system is set to automatic control mode, a second electrically controlled valve 26 is installed at the first discharge joint 24, and the feed pipe 41 is connected to multiple branch pipes 44, which are respectively connected to the first discharge joints 24 of multiple sets of stirring devices 20. A liquid level sensor 27 is also installed in the stirring tank 21. The conveying system also includes a PLC control module 50. The stirring power mechanism 23, the liquid level sensor 27, the water pump 40, and the second electrically controlled valve 26 are all electrically connected to the PLC control module 50. Through this setup, the level sensor 27 can monitor the liquid level of the reagent in the mixing tank 21 in real time and transmit the data to the PLC control module 50. When the reagent in a certain mixing tank 21 reaches the preset feeding level, the PLC control module 50 can automatically control the corresponding second solenoid valve 26 to open and the water pump 40 to start, drawing the reagent from the mixing tank 21. If the reagent level in a certain mixing tank 21 is too low, the PLC control module 50 can automatically close the corresponding second solenoid valve 26 and switch to feeding from other mixing tanks 21 with sufficient liquid levels. At the same time, the PLC control module 50 can also control the stirring motion. The operation of the force mechanism 23 is linked and controlled to ensure that the mixing and feeding operations are coordinated. This not only greatly reduces the intensity of manual operation, but also further improves the continuity, stability and accuracy of feeding, which is suitable for the production needs of large-scale, highly automated metal surface pretreatment agents. In addition, in order to prevent the liquid level in the feeding tank assembly 31 from being too high, a liquid level sensor 27 can also be installed in the feeding tank assembly 31 for control based on the PLC control module 50. Seamless switching of the mixing tank 21 can be completed without manual intervention, eliminating the downtime of feeding switching.

[0026] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
