Description

Technical Field

[0001] This application relates to the field of zinc battery raw material powder grinding and mixing technology, and in particular to an automatic grinding machine for zinc-based battery electrode powder. Background Technology

[0002] In the production process of zinc batteries, the grinding of electrode powder is a crucial step. If the electrode powder is ground in a metal container, the friction between the grinding bowl and the grinding rod during the grinding process will cause wear on the metal bowl or grinding rod. If metal powder mixes into the powder, it will react with the base material in the powder, thereby affecting the battery performance.

[0003] The existing solution is to use an agate mortar or ceramic mortar with a grinding rod, and then grind the ingredients by hand.

[0004] However, existing technologies have the following problems and drawbacks: 1. Manual grinding is labor-intensive and prone to human error, and prolonged manual operation can easily lead to worker fatigue; 2. Human resources are limited, and the amount of powder ground each time cannot be too large, making manual grinding inefficient for mass production. Therefore, an automatic grinding machine for zinc-based battery electrode powder is proposed. Utility Model Content

[0005] To address the existing problems of human fatigue and low production efficiency, this application provides an automatic grinding machine for zinc-based battery electrode powder.

[0006] The automatic grinding machine for zinc-based battery electrode powder provided in this application adopts the following technical solution:

[0007] An automatic grinding machine for zinc-based battery electrode powder includes:

[0008] The frame is made of welded square tubing, with sheet metal welded to the front and back sides, and movable doors on the left and right sides equipped with flat latches.

[0009] There are two movable doors, one on each side of the frame. The frame is equipped with a power indicator light and a start switch. The power indicator light lights up when the power is on, serving as an indicator of the equipment's energized status. The start switch is used to turn the grinding process on and off. A rotary motor is fixedly installed on the top of the frame. The rotary motor is an asynchronous motor equipped with a frequency converter, which provides power for the rotating platform.

[0010] The vacuuming mechanism is mounted on the frame;

[0011] Four seated bearings are provided. Two of the four seated bearings are fixedly mounted on the frame, while the other two seated bearings are fixedly mounted with grinding cover plates. The seated bearings are the connecting shafts between the grinding cover plates and the frame, and the rotating shafts for opening and closing. The grinding cover plates are the mechanisms required for the operation of the grinding rods. They are connected to the frame by the seated bearings and serve to facilitate operation when loading and unloading powder.

[0012] Furthermore, the dust collection mechanism includes a receiving box, which is fixedly installed on the frame, a fan is rotatably mounted on the receiving box, and a dust collection pipe is provided on the receiving box.

[0013] Furthermore, a flange is installed on the shaft of the rotary motor, and a rotating platform is set on the flange. A grinding bowl is set on the top of the rotating platform. The center of the grinding bowl is concentric with the center of the rotating platform. The rotating platform is driven to rotate by the motor, and the grinding bowl on the platform rotates accordingly. The grinding rod is driven by the connecting rod to move linearly for grinding. Three bowl fixing blocks are evenly fixed around the grinding bowl. The grinding bowl is used to hold the electrode powder to be ground, and the bowl fixing blocks are used to fix the grinding bowl to prevent it from moving or falling during the grinding process.

[0014] Furthermore, the four bearings with seats are connected by a through shaft to the grinding cover plate for opening and closing movement. The frame is provided with two opening and closing latches, which cooperate with the grinding cover plate. The opening and closing latches are the fixing latches when the grinding cover plate is closed, and their function is to prevent the grinding cover plate from loosening or opening during the grinding process.

[0015] Furthermore, a baffle block is fixedly installed on the grinding cover plate. During the grinding process, the powder is pressed towards both sides of the grinding rod's moving path. The function of the baffle block is to push the powder onto the moving path of the grinding rod, ensuring that all the powder is effectively ground. The grinding cover plate is equipped with a baffle block, and a grinding rod is fixedly installed at the bottom of the baffle block. The grinding rod is used to hold the electrode powder to be ground. A linear guide rail is provided on the grinding pressure adjustment mechanism. The linear guide rail is the moving guide rail for the grinding rod and the pressure adjustment mechanism. A guide shaft is provided on the grinding pressure adjustment mechanism. The guide shaft is connected and fixed to the rotating platform. When rotating, it moves along the guide rail, causing the grinding rod to move on the linear guide rail.

[0016] Furthermore, the grinding pressure adjustment mechanism consists of a spring and an adjustable screw. Adjusting the distance of the screw can adjust the pressure of the grinding rod. The rotating platform and the guide shaft cooperate with each other.

[0017] Furthermore, all three bowl-fixing blocks are mounted on a rotating platform, with the grinding bowl and grinding rod working together.

[0018] In summary, this application includes at least one of the following beneficial technical effects:

[0019] 1. This solution replaces manual labor with equipment. The original method of manually holding a grinding rod and grinding electrode powder in a grinding bowl can grind about 600g each time, and the grinding time for each time is required to be 1 hour. The equipment can grind 2500g each time, the powder loading time is about 10 minutes, and the automatic grinding time of the equipment is 3 hours, which effectively improves the problem of manual fatigue.

[0020] 2. The equipment can grind 2500g per batch, with a powder loading time of about 10 minutes and an automatic grinding time of 3 hours. Manual grinding can grind about 600g per batch, with a grinding time of 1 hour per batch. The equipment grinding efficiency is about 1.3 times that of manual grinding, thus improving production efficiency. Attached Figure Description

[0030] The following is in conjunction with the appendix Figures 1-8 This application will be described in further detail.

[0031] Example 1

[0032] An installation method for an automatic grinding machine for zinc-based battery electrode powder is described below. Figure 1 ,include:

[0033] Rack 1;

[0034] The frame 1 is made of square tubing welded together. The front and rear sides are fixed by sheet metal welding. The left and right sides are movable doors with flat latches. The power indicator light 3 and start switch 4 are installed on the front sheet metal. The top mounting plate has a rotary motor 2 in the center, with the motor shaft protruding above the mounting plate surface.

[0035] Reference Figure 2 The circular rotating platform 5 is connected to the central flange and is mounted on the shaft of the rotating motor 2.

[0036] Reference Figure 3 The center of the grinding bowl 6 is concentric with the center of the rotating platform 5, and the grinding bowl 6 is fixed in place by three bowl fixing blocks 7.

[0037] Reference Figure 4 Below the grinding pressure adjustment mechanism 10, a grinding rod 8 is installed. The grinding pressure is adjusted by the spring inside the grinding pressure adjustment mechanism 10. When the rotating platform 5 rotates, it drives the guide shaft 9 to move along the surrounding guide rails. The grinding mechanism will move back and forth in a straight line on the linear guide rail 12. The baffle block 11 is fixed on the grinding cover plate 14 and passes through the grinding mechanism to block the electrode powder in the grinding bowl 6 to the grinding position of the grinding rod 8.

[0038] Reference Figure 5 Two bearings 13 with seats are mounted on the frame 1 and two are mounted on the grinding cover plate 14. The grinding cover plate 14 is connected by a through shaft to open and close. After the grinding cover is closed, it is locked and fixed by the opening and closing lock 15.

[0039] Reference Figure 6When opened, the grinding mechanism and baffle plate mounted on the grinding cover flip upwards together, making it easy to add the electrode powder to be ground into the grinding bowl 6. After the powder is ground, the bowl body fixing block 7 can be loosened after opening the grinding cover, and the grinding bowl 6 can be removed together, poured out, and then put back in its original position.

[0040] Reference Figure 7 After adding the electrode powder to be ground into the grinding bowl 6, close the grinding cover, fix the grinding cover with the opening and closing lock 15, turn on the grinding start switch 4, and start grinding. During grinding, the rotating platform 5 rotates, driving the guide shaft 9 to move along the surrounding guide rails. The grinding mechanism will drive the grinding rod 8 to grind back and forth in a straight line on the linear guide rail 12. The baffle plate will block the electrode powder to the grinding position of the grinding rod 8 for grinding.

[0041] Reference Figure 8 The dust collection mechanism includes a housing 17, which is fixedly installed on the frame 1. A fan 18 is rotatably mounted on the housing 17, and a dust collection pipe 16 is provided on the housing 17.

[0042] The implementation principle of an automatic grinding machine for zinc-based battery electrode powder in this application embodiment is as follows: the powder is loaded into the bowl, and then the bowl is placed on the machine table. The motor is started, and the rotating table begins to rotate. The platform guide rail is driven by the connecting rod to move, thereby causing the grinding rod 8 to move above the bowl according to a predetermined trajectory. At the same time, the baffle plate guides the powder under the grinding rod 8. Under the pressure of the grinding rod 8, the powder is ground. When loading and unloading materials, the grinding platform is opened. After the operation is completed, the grinding platform is closed and the grinding machine is started again. The fan 18 rotates and blows air, so that the dust suction pipe 16 sucks the dust generated during grinding into the container 17 for storage, so that the frame 1 remains clean and tidy.

[0043] Example 2

[0044] The difference between this embodiment and embodiment one is that a support frame is provided on the suction pipe 16, and one end of the support frame is fixedly installed on the frame 1. The suction pipe 16 is supported by the support frame, which can increase the life of the suction pipe 16.

[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
