Description

Technical Field

[0001] This utility model relates to the field of battery processing technology, and in particular to an alkaline battery graphite spraying and drying equipment. Background Technology

[0002] During the production of alkaline batteries, a 5-10µm thick graphite coating needs to be sprayed onto the inner wall of the steel casing. The purpose of this coating is to reduce the battery's internal resistance and increase its conductivity. Currently, the graphite coatings used are generally divided into two types: water-soluble graphite and oil-based graphite. Water-soluble graphite coatings are more environmentally friendly, as they do not produce VOCs, but they are more difficult to dry.

[0003] During the graphite spraying and drying process, drying is mostly carried out on the outside of the steel shell. However, during the drying process, a large amount of hot and humid air is generated inside the battery steel shell. If it cannot be removed in time, it will affect the drying efficiency of the sprayed graphite layer.

[0004] Therefore, in order to advance industry technology, better achieve the drying efficiency of alkaline battery graphite spraying, and improve core technological competitiveness, this application proposes a new implementation scheme that differs from the existing alkaline battery graphite spraying drying equipment and application methods. Utility Model Content

[0005] The purpose of this invention is to solve the problem that in the existing graphite spraying and drying process, drying is mostly carried out on the outside of the steel shell. However, during the drying process, a large amount of hot and humid air is generated inside the steel shell of the battery. If it cannot be removed in time, it will affect the drying efficiency of the sprayed graphite layer. Therefore, an alkaline battery graphite spraying and drying device is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An alkaline battery graphite spraying and drying device includes a first workbench, a second workbench, and a battery steel shell. The bottom inner wall of the first workbench is provided with a first rotating disk, and the bottom inner wall of the second workbench is rotatably connected to a second rotating disk. A transmission belt is driven between the first and second rotating disks, and the top of the transmission belt is provided with multiple locking mechanisms. A heating wire is fixedly connected to the circumferential inner wall of the first workbench. A top cover is fixedly connected to the top of the first workbench, and an electric push rod is fixedly connected to the top of the top cover. A partition is fixedly connected to the bottom of the electric push rod. The partition slides between the circumferential inner walls of the first workbench. An air collection box is fixedly connected to the bottom of the partition. Multiple exhaust pipes are sealed and inserted into the circumference of the air collection box, and multiple through holes are provided at the other end of the exhaust pipes.

[0008] Furthermore, a rotating ring is fixedly connected to the bottom of the first rotating disk, and a support base is fixedly connected to the bottom inner wall of the first worktable, with the rotating ring rotating on the support base.

[0009] Furthermore, the snap-fit ​​mechanism includes multiple snap-fit ​​brackets, which are fixed to the top of the transmission belt by bolts. Two snap rings are fixedly connected to one side of the snap-fit ​​bracket, and a base is fixedly connected inside one of the snap rings. The battery steel shell is placed on the base and snapped into the snap ring.

[0010] Furthermore, the bottom inner wall of the first worktable and the bottom inner wall of the second worktable are rotatably connected to two guide rollers, and the transmission belt is wound around the guide rollers.

[0011] Furthermore, a temperature controller is fixedly connected to one side of the outer wall of the first workbench, and the temperature controller is electrically connected to the heating wire.

[0012] Furthermore, a drive motor is fixedly connected to the bottom outer wall of the first worktable, and the output end of the drive motor is fixedly connected to the bottom of the first rotating disk.

[0013] Furthermore, an exhaust fan is fixedly connected to the top of the top cover, and a connecting hose is sealed and inserted into the air inlet end of the exhaust fan. The other end of the connecting hose is sealed and inserted into the top of the air collection box.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. The partition moves downward under the drive of the electric push rod, which in turn moves the air collection box downward. This causes the exhaust pipe to be inserted into the battery steel shell at the perforated end. Then, under the action of the exhaust fan, the hot and humid air inside the battery steel shell is drawn into the exhaust pipe through the perforation. The air is then fed into the external equipment for processing through the connecting hose, thereby timely expelling the hot and humid air and improving the drying efficiency.

[0016] 2. By placing the battery steel casing on the base and within the retaining ring, the battery steel casing can be quickly and securely installed for transport. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-4 An alkaline battery graphite spraying and drying device includes a first workbench 1 and a second workbench 2. The bottom inner wall of the first workbench 1 is provided with a first rotating disk 3. The bottom inner wall of the second workbench 2 is rotatably connected to a second rotating disk 4 via bearings. A transmission belt 5 is connected between the first rotating disk 3 and the second rotating disk 4. A drive motor 17 is fixed to the bottom outer wall of the first workbench 1 by bolts. The output end of the drive motor 17 is fixedly connected to the bottom of the first rotating disk 3. Under the drive of the drive motor 17, the first rotating disk 3 rotates, thereby driving the transmission belt 5 to rotate, and then driving the battery steel shell 18 to rotate, thereby conveying the battery steel shell 18.

[0024] The top of the transmission belt 5 is provided with multiple snap-fit ​​mechanisms, each including multiple plug-in brackets 501. The plug-in brackets 501 are fixed to the top of the transmission belt 5 by bolts. Two snap rings 502 are welded to one side of the plug-in brackets 501. A base 503 is welded inside one of the snap rings 502. The battery steel shell 18 is placed on the base 503 and snapped into the snap ring 502. Placing the battery steel shell 18 on the base 503 and within the snap ring 502 facilitates the fixation of the battery steel shell 18.

[0025] Heating wires 9 are fixed to the inner circumference of the first workbench 1 by bolts. The heating range of heating wires 9 is 80-120℃. Heating wires 9 are evenly distributed along the inner circumference of the first workbench 1. A temperature controller 10 is fixed to the outer wall of one side of the first workbench 1 by bolts. The temperature controller 10 is electrically connected to the heating wires 9. Its model can be selected according to the actual situation, such as KP71 (060L111366) of the DANFOSS series. The working state of the heating wires 9 is controlled by the temperature controller 10. The target temperature is set by the buttons and digital display panel. The internal circuit of the temperature controller converts this signal into a control reference, thereby controlling the heating temperature of the heating wires 9. The heating wires 9 are used to heat and dry the battery steel shell 18.

[0026] The top of the first workbench 1 is fixed with a top cover 11 by bolts. The top of the top cover 11 is fixed with an electric push rod 13 by bolts. The bottom of the electric push rod 13 is fixed with a partition 12 by bolts. The partition 12 slides between the inner circumference of the first workbench 1. The bottom of the partition 12 is fixed with an air collection box 14 by bolts.

[0027] Multiple exhaust pipes 15 are circumferentially sealed and inserted into the air collection box 14. Multiple through holes 16 are provided at the other end of the exhaust pipes 15. Under the drive of the electric push rod 13, the partition 12 moves downward, thereby driving the air collection box 14 to move downward, so that the exhaust pipes 15 are inserted into the battery steel shell 18 at one end of the through hole 16.

[0028] The top of the top cover 11 is fixed with an exhaust fan 19 by bolts. The air inlet end of the exhaust fan 19 is sealed with a connecting hose 20. The other end of the connecting hose 20 is sealed with the top of the air collection box 14. Under the action of the exhaust fan 19, the hot and humid air inside the battery steel shell 18 is drawn into the exhaust pipe 15 through the perforation 16. Then, it is input into the external equipment for processing through the connecting hose 20, so as to discharge the hot and humid air in time and improve the drying efficiency of the battery steel shell 18.

[0029] A rotating ring 6 is welded to the bottom of the first rotating disk 3, and a support seat 7 is welded to the inner wall of the bottom of the first worktable 1. The rotating ring 6 rotates on the support seat 7, thereby providing support for the rotation of the first rotating disk 3.

[0030] Two guide rollers 8 are rotatably connected to the bottom inner wall of the first workbench 1 and the bottom inner wall of the second workbench 2. The transmission belt 5 is wound around the guide rollers 8, thereby guiding the transmission belt 5.

[0031] The working principle of this embodiment is as follows: In use, at the second workbench 2 end, the graphite-sprayed battery steel shell 18 is placed on the base 503 and can be placed within the retaining ring 502. Then, the drive motor 17 is started by controlling the control panel. Under the drive motor 17, the first rotating disk 3 rotates, thereby driving the transmission belt 5 to rotate, which in turn drives the battery steel shell 18 to rotate, thus conveying the battery steel shell 18 into the first workbench 1. The battery steel shell 18 is then heated and dried using the heating wire 9, and the temperature of the heating wire 9 is controlled by the temperature controller 10. The hot and humid air generated during drying is controlled by the control panel to start the electric push rod 13 and the exhaust fan 19. Driven by the electric push rod 13, the partition 12 moves downward, thereby moving the air collection box 14 downward. This causes the exhaust pipe 15 to be inserted into the battery steel shell 18 at one end of the perforation 16. Then, under the action of the exhaust fan 19, the hot and humid air inside the battery steel shell 18 is drawn from the perforation 16 into the exhaust pipe 15. Then, it is introduced into the external equipment for processing through the connecting hose 20, so as to expel the hot and humid air in time and better dry the battery steel shell 18.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
