Description

Technical Field

[0001] This utility model relates to the field of packaging equipment technology, specifically to an automatic packaging equipment for micronized lithium hydroxide. Background Technology

[0002] Micronized lithium hydroxide refers to lithium hydroxide particles with a particle size of less than a few micrometers. Compared with traditional micron-sized lithium hydroxide powder, micronized lithium hydroxide has a finer particle morphology, higher specific surface area and reactivity, as well as better dispersibility and flowability. Micronized lithium hydroxide is often used in battery electrolytes, lithium salt preparation, and the production of high-nickel ternary cathode materials.

[0003] When producing micronized lithium hydroxide, it needs to be packaged. However, it is inconvenient to package in quantitative quantities according to demand. Moreover, after packaging, it is often necessary for staff to remove it and put it into a sealing machine for sealing, which is quite troublesome. The separate loading and sealing process leads to low packaging efficiency, so it is urgent to improve. Utility Model Content

[0004] The purpose of this invention is to provide an automatic packaging device for micronized lithium hydroxide to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic packaging device for micronized lithium hydroxide, comprising a device platform, a device frame, a hopper, a weighing hopper, and a heat sealing strip. The device frame is welded to one side of the top of the device platform. The hopper is fixed to one side of the device frame, and a discharge port is installed at the bottom of the hopper. A weighing frame is fixed to the outer wall of the device frame below the hopper, and weighing blocks are installed on both sides of the top of the weighing frame. The weighing hopper is located inside the weighing frame, and a discharge pipe is installed at the bottom of the weighing hopper. Side plates are welded to the outer walls of the device frame on both sides of the discharge pipe. A third cylinder is installed on the surface of the side plate. The heat sealing strip is installed at the output end of the third cylinder. A packaging bag is located below the discharge pipe.

[0006] Preferably, a first cylinder is installed inside the equipment platform, and a packaging platform is fixed to the output end of the first cylinder.

[0007] Preferably, a rotating rod is installed at the center of the hopper, and a propeller is fixed at the bottom of the rotating rod, with the propeller extending into the interior of the discharge port.

[0008] Preferably, a servo motor is installed at the center of the top of the hopper, and the output end of the servo motor is fixedly connected to the rotating rod.

[0009] Preferably, a baffle is installed inside the discharge pipe via a rotating shaft, and a stepper motor is installed on the outer wall of the discharge pipe at the position of the baffle, with the output end of the stepper motor fixedly connected to the baffle.

[0010] Preferably, a second cylinder is mounted on the side plate surface above the third cylinder, and an arc-shaped clamp is mounted on the output end of the second cylinder.

[0011] Preferably, the weighing hopper passes through the weighing frame, and the weighing hopper is in close contact with the weighing block.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] A servo motor drives a rotating rod to rotate, which in turn drives a propeller to rotate. This causes the fine lithium hydroxide powder inside the hopper to fall into the weighing hopper through the discharge port. The weighing block at the top of the weighing frame weighs the hopper. When the weight reaches the preset value, the servo motor stops rotating and stops discharging. The stepper motor drives the baffle to flip, causing the fine lithium hydroxide powder inside the weighing hopper to fall into the packaging bag through the discharge pipe, thus facilitating quantitative packaging.

[0014] The packaging bag is placed on the packaging table. The first cylinder drives the packaging table to move upward, so that the opening of the packaging table fits over the outside of the discharge pipe. The second cylinder drives the arc-shaped clamp to extend, clamping the packaging bag over the outside of the discharge pipe and sealing the opening of the packaging bag to prevent the lithium hydroxide powder from scattering during feeding. The second cylinder drives the arc-shaped clamp to retract and release the packaging bag. The first cylinder drives the packaging table to move downward, causing the packaging bag to move downward, and the opening of the packaging bag moves down to the position of the heat sealing strip. The third cylinder drives the heat sealing strip to extend, clamping the opening of the packaging bag and heat sealing it. This design can seal the packaging opening immediately, improving packaging efficiency. Attached Figure Description

[0022] Please see Figure 1-4 An embodiment of this utility model is provided: an automatic packaging device for micronized lithium hydroxide, including a device platform 1, a device frame 4, a hopper 5, a weighing hopper 10 and a heat sealing strip 19. The device frame 4 is welded to one side of the top of the device platform 1. The hopper 5 is fixed to one side of the device frame 4, and a discharge port 9 is installed at the bottom of the hopper 5. A weighing frame 15 is fixed on the outer wall of the device frame 4 below the hopper 5, and weighing blocks 16 are installed on both sides of the top of the weighing frame 15.

[0023] The weighing hopper 10 is located inside the weighing rack 15, and a discharge pipe 11 is installed at the bottom of the weighing hopper 10.

[0024] Specifically, the servo motor 6 drives the rotating rod 7 to rotate, and the rotating rod 7 drives the propeller 8 to rotate, so that the micro-powdered lithium hydroxide inside the hopper 5 falls into the weighing hopper 10 through the discharge port 9. At this time, the weighing block 16 at the top of the weighing frame 15 weighs the weighing hopper 10. When the weight reaches the preset value, the servo motor 6 stops rotating and stops discharging. At this time, the micro-powdered lithium hydroxide in the weighing hopper 10 is the amount for a single package, which facilitates quantitative packaging.

[0025] Side plates 12 are welded to the outer walls of the equipment frame 4 on both sides of the discharge pipe 11. A third cylinder 18 is installed on the surface of the side plate 12. A heat sealing strip 19 is installed at the output end of the third cylinder 18. A packaging bag 20 is set below the discharge pipe 11.

[0026] The first cylinder 2 is installed inside the equipment platform 1, and the output end of the first cylinder 2 is fixed to the packaging platform 3;

[0027] A rotating rod 7 is installed at the center of the hopper 5, and a propeller 8 is fixed at the bottom of the rotating rod 7. The propeller 8 extends into the interior of the discharge port 9.

[0028] A servo motor 6 is installed at the center of the top of the hopper 5, and the output end of the servo motor 6 is fixedly connected to the rotating rod 7.

[0029] A baffle 17 is installed inside the discharge pipe 11 via a rotating shaft, and a stepper motor 21 is installed on the outer wall of the discharge pipe 11 at the position of the baffle 17. The output end of the stepper motor 21 is fixedly connected to the baffle 17.

[0030] The second cylinder 13 is mounted on the surface of the side plate 12 above the third cylinder 18, and the output end of the second cylinder 13 is mounted with an arc-shaped clamping plate 14.

[0031] Specifically, the packaging bag 20 is placed on the packaging table 3. By operating the external control panel, the first cylinder 2 drives the packaging table 3 to move upward, so that the opening of the packaging table 3 fits over the outside of the discharge pipe 11. Next, the second cylinder 13 drives the arc-shaped clamp 14 to extend. The arc-shaped clamp 14 clamps the packaging bag 20 over the outside of the discharge pipe 11, sealing the opening of the packaging bag 20 to prevent the lithium hydroxide powder from scattering during feeding. Then, the stepper motor 21 drives the baffle 17 to flip, so that the lithium hydroxide powder inside the weighing hopper 10 falls into the packaging bag 20 through the discharge pipe 11.

[0032] The second cylinder 13 drives the arc-shaped clamping plate 14 to retract and release the packaging bag 20. The first cylinder 2 drives the packaging table 3 to move down, causing the packaging bag 20 to move down. The opening of the packaging bag 20 moves down to the position of the heat sealing strip 19. The third cylinder 18 drives the heat sealing strip 19 to extend. The heat sealing strip 19 clamps the opening of the packaging bag 20 and heat seals it. This design can seal the packaging opening immediately, improving packaging efficiency.

[0033] The weighing hopper 10 passes through the weighing frame 15, and the weighing hopper 10 is in close contact with the weighing block 16.

[0034] In this embodiment, the following steps are taken: First, the servo motor 6 drives the rotating rod 7 to rotate, which in turn drives the propeller 8 to rotate, causing the micro-powdered lithium hydroxide inside the hopper 5 to fall into the weighing hopper 10 through the discharge port 9. At this time, the weighing block 16 at the top of the weighing frame 15 weighs the weighing hopper 10. When the weight reaches the preset value, the servo motor 6 stops rotating and stops discharging. At this time, the micro-powdered lithium hydroxide in the weighing hopper 10 is the amount for a single package, which facilitates quantitative packaging. Then, the packaging bag 20 is placed on the packaging platform 3. By operating the external control panel, the first cylinder 2 drives the packaging platform 3 to move upward, so that the opening of the packaging platform 3 fits over the outside of the discharge pipe 11. Next, the second cylinder 13 drives the arc-shaped clamping plate 14 to extend. The arc-shaped clamp 14 clamps the packaging bag 20 outside the discharge pipe 11, sealing the opening of the packaging bag 20 to prevent the lithium hydroxide powder from scattering during feeding. Then, the stepper motor 21 drives the baffle 17 to flip, so that the lithium hydroxide powder inside the weighing hopper 10 falls into the packaging bag 20 through the discharge pipe 11. Immediately afterwards, the second cylinder 13 drives the arc-shaped clamp 14 to retract and release the packaging bag 20. The first cylinder 2 drives the packaging platform 3 to move down, so that the packaging bag 20 moves down and the opening of the packaging bag 20 moves down to the position of the heat sealing strip 19. The third cylinder 18 drives the heat sealing strip 19 to extend, and the heat sealing strip 19 clamps the opening of the packaging bag 20 and heat seals it. This design can seal the packaging opening immediately, improving packaging efficiency.

[0035] Obviously, the embodiments described above 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 should fall within the protection scope of this utility model.
