[0019] To solve the above technical problems, such as Figures 1-5As shown, this utility model designs a high-speed coating production line for alkaline battery steel shells, including a steel shell conveying and sorting system 1, a steel shell coating machine 2, a conductive film spraying system 3, a drying device 4, and a testing device 5. The steel shell conveying and sorting system 1 has two symmetrical conveying paths. The steel shell conveying and sorting system 1, the steel shell coating machine 2, the drying device 4, and the testing device 5 are arranged sequentially from front to back. The conductive film spraying system 3 is located on the side of the steel shell conveying and sorting system 1. The steel shell conveying and sorting system 1 uses... The steel shells that have been sorted and whose cylinder dimensions are qualified are fed into the track input end of the steel shell coating machine 2, while the steel shells that have not been sorted are sent back to the discharge hopper 11. At the same time, the steel shells that have been sorted but whose cylinder dimensions are not qualified are sent to the waste collection box 112. The steel shell coating machine 2 is used to simultaneously coat the inside of the cylinders of the steel shells transported by the two sets of conveying paths of the steel shell conveying and sorting system 1. The conductive film spraying system 3 is connected to the spray gun inside the steel shell coating machine 2. The drying device 4 is used to dry the coated steel shells. The detection... Device 5 is used to inspect the dried steel shells. By integrating the steel shell conveying and sorting system 1, the steel shell coating machine 2, the conductive film spraying system 3, the drying device 4, and the inspection device 5, a complete production line is formed, realizing a continuous and efficient production process. This significantly improves the production efficiency of alkaline battery steel shells. Because the steel shells have already undergone size and quality screening before entering the coating process, it ensures that only qualified steel shells enter subsequent processes, thereby improving the quality of the final product. The sequential arrangement of each device reduces the time and space required for material flow, making the production line layout more compact and improving space utilization efficiency. The automated design of the entire production line reduces manual operation and labor intensity, while also improving the continuous operation capability of the production line. Overall, it achieves improved production efficiency, optimized quality control, improved space utilization, enhanced production flexibility, reduced energy consumption, increased automation, convenient maintenance and cleaning, improved environmental adaptability, and enhanced safety, providing an efficient, stable, and reliable solution for the production of alkaline battery steel shells.

[0020] In this embodiment, it is further preferred that the steel shell conveying and sorting system 1 includes a discharge hopper 11, a vertical elevator 12, and a material distribution conveying mechanism. Two sets of discharge hoppers 11 are symmetrically arranged left and right. The symmetrical two sets of conveying paths improve the system's balance and stability, and allow double the number of steel shells to be processed simultaneously, thereby improving overall production efficiency. The top of the discharge hopper 11 has an opening, and the interior of the discharge hopper 11 has a downward-sloping guide surface. The bottom end of the guide surface faces the feed inlet of the discharge hopper 11. Two sets of vertical elevators 12 are respectively arranged in front of the discharge hoppers 11. The conveyor belts of the vertical elevators 12 are arranged in an inverted L-shape. The bottom of the vertical elevators 12 communicates with the feed inlet of the discharge hoppers 11, and the top of the vertical elevators 12... The unit is equipped with a discharge hopper 13. The inverted L-shaped arrangement of the vertical elevator 12 effectively utilizes space and simultaneously achieves efficient vertical transport of the steel shell from the discharge hopper 11 to the discharge hopper 13, reducing the waiting and accumulation time of the steel shell during the conveying process. The material distribution and conveying mechanism includes a screening hopper 14, guide rods 15, a drive motor 16, a synchronous pulley 17, a collection hopper 18, a first horizontal conveyor 19, and a support 110. The support 110 is fixedly installed between the vertical elevator 12 and the steel shell coating machine 2. The collection hopper 18 is fixedly installed above the support 110. The collection hopper 18 is inclined downward from front to back. The lowest end of the collection hopper 18 is provided with a cylindrical discharge section, which is located inside the waste collection box 112. The two guide rods 15 are positioned on the left and right sides. The guide rod 15 is positioned above the collecting hopper 18, with its axial direction parallel to the upper edge of the collecting hopper 18. The spacing between the two guide rods 15 is adapted to the shell of the steel shell. The end of each guide rod 15 is fixedly connected to a synchronous wheel 17, which are bonded together. One of the synchronous wheels 17 is connected to the output shaft of the drive motor 16 via a transmission belt. The screening hopper 14 is positioned above the guide rods 15 and below the discharge hopper 13. The bottom of the screening hopper 14 has a through hole leading to the inner gap of the two guide rods 15. A return pipe 111 is also provided on one side of the screening hopper 14, facing the input end of the first horizontal conveyor 19. The guide rods 15 are used to feed the steel shells, which have been arranged and whose cylinder dimensions are qualified, into the steel shell coating machine. At the track input end of 2, the first horizontal conveyor 19 is used to send unsorted steel shells back to the discharge hopper 11. This design reduces the time and complexity of material return and improves material flow efficiency. The collection hopper 18 is used to send steel shells that have been sorted but have fallen from the gaps in the guide rod 15 due to unqualified cylinder size to the waste collection bin 112. The system can send unsorted steel shells back to the discharge hopper 11, ensuring that only sorted steel shells enter the coating machine, improving the orderliness of the production process and product quality. For steel shells that have been sorted but have unqualified cylinder size, the system can send them to the waste collection bin 112. This size screening function reduces the risk of unqualified products flowing into subsequent processes and also automates waste processing.This reduces labor costs and time associated with waste disposal, improves product consistency and reliability, and automates material sorting and screening to reduce the need for manual operation, lower labor intensity, reduce human error, and enhance production process stability and product consistency.

[0021] In this embodiment, it is further preferred that the steel shell coating machine 2 includes a positioning conveyor turntable 21 and a coating module 22. The positioning conveyor turntable 21 is located at the transmission end of the guide rod 15 of the steel shell conveying and sorting system 1. The axis of the positioning conveyor turntable 21 is perpendicular to the guide rod 15. The positioning conveyor turntable 21 rotates intermittently. The positioning conveyor turntable 21 is provided with a plurality of positioning slots arranged in a circular array. Magnetic adsorption blocks are installed in the positioning slots. The positioning conveyor turntable 21 is used to send the steel shells sent by the guide rod 15 into the track of the coating module 22. The intermittent rotation of the positioning conveyor turntable 21 ensures that the steel shells can be accurately positioned before entering the coating module 22, improving the accuracy and consistency of the coating process. At the same time, it optimizes the spatial layout, making the entire coating area more compact and saving space in the production line. The continuous rotation of the positioning conveyor turntable 21 and the coordinated work of the steel shell coating machine 2 ensure the continuity of the production process and reduce production interruptions caused by improper positioning.

[0022] In this embodiment, it is further preferred that the conductive film spraying system 3 includes a housing 31, with a lifter 32 located at the bottom inner side of the housing 31. A container 33 is mounted on the lifting plate of the lifter 32. A fixing plate 34 is also located inside the housing 31, and a stirring module 35 is mounted on the fixing plate 34. After the lifter 32 raises the container 33, the stirring shaft of the stirring module 35 extends into the inside of the container 33. The design of the lifter 32 and container 33 inside the housing 31 makes the supply of coating more precise and controllable. After the container 33 is raised, the stirring module 35 can evenly stir the coating to ensure the spraying quality. The machine box 31 is also equipped with a pump body 36, which connects the container 33 to the spray gun of the coating module 22 through a pipeline. This realizes efficient transfer and use of the coating, reduces coating waste, improves coating utilization, simplifies the coating stirring and supply process, makes operation more convenient, reduces the labor intensity of operators, and ensures uniform mixing of the coating before spraying, thereby ensuring the stability and consistency of the spraying quality.

[0023] In this embodiment, it is further preferred that the drying device 4 includes a second horizontal conveyor 41, the input end of which is located below the guide rail outlet end of the coating module 22. The second horizontal conveyor 41 has a synchronous belt 42 that can reciprocate linearly in the horizontal direction. The synchronous belt 42 has a plurality of grooves evenly spaced along its length, which cause the steel shell to be arranged laterally in the axial direction. A high-pressure hot air knife 43 is mounted on one side of the second horizontal conveyor 41 via a support frame. The air outlet of the high-pressure hot air knife 43 faces the synchronous belt 42. A [further details about the second horizontal conveyor 41 are missing from the original text.] A high-pressure hot air blower 44 is provided, which is connected to a high-pressure hot air knife 43. The transmission end of the second horizontal conveyor 41 is provided with a material drop cover 45, and a material box 46 is provided below the material drop cover 45. Through the design of the second horizontal conveyor 41, the steel shell can quickly enter the drying area after coating, realizing seamless connection with the coating process and improving drying efficiency. Since the steel shell is set in the left and right direction in the axial direction, the high-pressure hot air knife 43 can evenly dry the inside of the steel shell, ensuring the uniform distribution of heat energy on the entire cross section of the steel shell, avoiding the problem of local overheating or incomplete drying, and improving the drying quality.

[0024] In this embodiment, it is further preferred that the detection device 5 includes a support base 51, a detection probe 52, an air blowing pipe 53, and a waste box 54. The support base 51 is fixed to one side of the rear of the second horizontal conveyor 41, located between the high-pressure hot air knife 43 and the material discharge baffle 45. The detection probe 52 and the air blowing pipe 53 are fixed to the support base 51. The detection probe 52 is located in front of the air blowing pipe 53, with the detection end of the probe 52 and the air outlet end of the air blowing pipe 53 both facing the synchronous belt 42 of the second horizontal conveyor. The waste box 54 is located below the support base 51. The detection device 5 ensures accurate quality inspection of the dried steel shell, improving the reliability and consistency of product quality. The use of the air blowing pipe 53 can promptly identify unqualified steel shells and remove defective products from the production line, reducing the risk of defective products flowing into subsequent processes. The detection device 5 is located between the high-pressure hot air knife 43 and the material drop baffle 45, ensuring that the steel shells have completed quality inspection before entering the next process, avoiding ineffective work and improving overall production efficiency. The reasonable layout of the detection device 5 makes the production line more compact, reduces space occupation, and facilitates monitoring and maintenance by operators. The automated detection device 5 reduces the need for manual inspection, lowers labor intensity, and reduces detection errors caused by human factors. The integration of the detection device 5 improves the automation level of the production line, making the production process more stable and predictable.

[0025] In practice, the steel shells enter the vertical elevator 12 through the discharge hopper 11. After being lifted to a certain height, they are further divided and sorted by the material distribution and conveying mechanism. The design of the discharge hopper 11 allows the steel shells to smoothly enter the vertical elevator 12, while the inclined guide surface helps the steel shells slide smoothly down. In the material distribution and conveying mechanism, the steel shells are screened by the screening hopper 14 and guide rod 15. Qualified steel shells are sent to the steel shell coating machine 2, while unqualified steel shells fall into the collection hopper 18 through the gaps in the guide rod 15 and are finally sent to the waste collection box 112. Qualified steel shells are sent by the guide rod 15 to the positioning conveying turntable 21 of the steel shell coating machine 2. The intermittent rotation of the turntable and the magnetic adsorption blocks ensure the precise positioning of the steel shells during the coating process. The coating module 22 internally coats the steel shell. After coating, the steel shell enters the drying device 4. The synchronous belt 42 of the second horizontal conveyor 41 transports the steel shell to one side of the high-pressure hot air knife 43 for uniform drying. After drying, the steel shell is inspected by the detection device 5. The detection probe 52 and the air blowing pipe 53 work together to ensure that only qualified steel shells can enter the next process. Unqualified steel shells are blown out of the production line and fall into the waste box 54. Qualified steel shells continue to move along the second horizontal conveyor 41 and finally fall into the material box 46, completing the entire production process. Throughout the entire process, the operator continuously monitors the operating status of the production line to ensure the normal operation of the equipment and performs necessary maintenance and adjustments.
