Description

Technical Field

[0001] The invention relates to a material unloading device, in particular to a lithium battery material unloading and packaging device. Background Art

[0002] Graphite is a material used for the negative electrode of lithium batteries. It is made by reacting coke powder particles at high temperature in a reactor. The dust generated by these coke powder particles during processing and transfer is easily raised. For example, in the process of packaging coke powder particles in the prior art, since the material is not fully sealed during packaging, a large amount of dust will be raised when the coke powder particles fall into the packaging bag. These dusts will float in the air and pollute the atmosphere, which does not meet environmental protection requirements. They will easily cause slipping when deposited on the floor of the workshop, causing people to fall or equipment to be damaged, posing a safety hazard. In addition, inhalation by the human body will damage human health. Therefore, these dusts must be handled in a timely manner. Summary of the invention

[0003] The object of the present invention is to provide a lithium battery material unloading and packaging device which can prevent dust from leaking into the external environment during unloading and packaging, reduce air pollution, effectively improve the production environment, and has high unloading efficiency.

[0004] In order to achieve the above-mentioned purpose, the lithium battery material unloading and packaging device provided by the present invention includes a fixed bracket, a hopper, a cover body, a barrel, a lifting mechanism and a fan; the hopper is fixed on the fixed bracket, and one end of the hopper is provided with an output tube, the output tube is sealed and extends into the interior of the cover body, and one end of the output tube is provided with a control valve for controlling the switch of the hopper; the cover body is arranged to be movable and liftable relative to the output tube; the barrel is arranged below the cover body to position the packaging bag so that the opening edge of the packaging bag is turned over to cover the edges around the opening of the barrel; the edges around the opening of the barrel are provided with a buffer pad, and when the cover body covers the opening of the barrel, the inner wall surface of the cover body elastically contacts the buffer pad; the lifting mechanism is arranged on the fixed bracket and the output end is connected to the cover body to drive the cover body to rise to open the barrel, or descend to cover the barrel; the fan is arranged on the fixed bracket and the input end is connected to the interior of the cover body, and the output end of the fan is connected to the hopper.

[0005] Compared with the prior art, the present invention provides a relatively sliding cover body on the output tube of the hopper, and provides a barrel for positioning the packaging bag under the cover body, and provides a buffer pad at the opening edge of the barrel, and uses a lifting mechanism to drive the cover body to rise or fall, so that the inner side wall of the cover body can be pressed against the buffer pad at the edge of the barrel; at the same time, the packaging bag opening on the edge of the barrel will also be clamped and fixed by the buffer pad and the cover body, so that the cover body and the inside of the packaging bag form a closed space, and when the hopper is unloaded, the raised dust can be prevented from leaking to the outside. In addition, by using the fan connected to the cover body to suck away the dust in time, the inside of the cover body can be quickly purified, and there is no need to wait for the dust to settle before removing the barrel, and the unloading speed is fast. In addition, by connecting the output end of the fan with the hopper, the sucked dust can be returned to the hopper and unloaded again, which not only avoids the waste of materials, but also does not require additional treatment of the dust, which is simple and practical. In summary, the present invention can prevent dust from leaking into the external environment during unloading and packaging, reduce air pollution, effectively improve the production environment, and has high unloading efficiency.

[0006] Preferably, the lithium battery material unloading and packaging device further comprises a screw feeder, which is arranged on the hopper to quantitatively feed the lithium battery material into the hopper. By controlling the feeding amount of the screw feeder, the material is pre-stored in the hopper, and the bag change operation can be performed at any time, which greatly reduces the unloading time and improves the unloading efficiency.

[0018] In order to explain the technical content, structural features and achieved effects of the present invention in detail, the following is a detailed description in conjunction with the implementation methods and the accompanying drawings.

[0019] like Figure 1 to Figure 2 As shown, the lithium battery material unloading and packaging device 100 of the present invention includes a fixed bracket 1, a hopper 2, a cover body 3, a barrel 4, a lifting mechanism 5, a fan 6 and a control system. The hopper 2 is fixed on the fixed bracket 1, and one end of the hopper 2 is provided with an output tube 21, and the output tube 21 extends into the interior of the cover body 3 in a sealed manner. One end of the output tube 21 is provided with a control valve 22 for controlling the opening and closing of the hopper 2. The cover body 3 is arranged to be movable relative to the output tube 21; the cover body 3 is a cone structure and a hard fixed shape structure, and the diameter of the upper end is smaller than the diameter of the lower end, that is, the cover body 3 is a structure that is narrow at the top and wide at the bottom, so that it can be matched with barrels 4 of different calibers, so as to be suitable for packaging bags 200 or barrels 4 of different capacities, thereby improving the applicability of the equipment. The barrel 4 is arranged below the cover body 3 to position the packaging bag 200, so that the opening edge of the packaging bag 200 is turned over to cover the edges around the opening of the barrel 4. The diameter of the opening of the barrel 4 is smaller than the diameter of the lower end of the cover 3 and larger than the diameter of the upper end of the cover 3. The edges of the opening of the barrel 4 are provided with a buffer pad 41. When the cover 3 covers the opening of the barrel 4, the inner wall surface of the cover 3 elastically contacts the buffer pad 41; the buffer pad 41 is a rubber ring. The cross section of the rubber ring is circular, elliptical or triangular. When the cross section of the rubber ring is triangular, the outer side of the triangle is inclined to cooperate with the oblique inner wall surface of the cover 3 to seal the inside of the cover 3. The lifting mechanism 5 is arranged on the fixed bracket 1 and the output end is connected to the cover 3 to drive the cover 3 to rise and open the barrel 4, or to descend and cover the barrel 4; the fan 6 is arranged on the fixed bracket 1 and the input end is connected to the inside of the cover 3, the output end of the fan 6 is connected to the hopper 2, and the output end 61 of the fan 6 is located between the contact position of the buffer pad 41 and the outlet of the output cylinder 21. The lifting mechanism, the fan 6 and the control valve 22 are electrically connected to the control system respectively, and the control system can control the start and stop of the first three.

[0020] Please refer to Figure 1A flexible cover 31 is provided between the upper end of the cover body 3 and the output cylinder, and the flexible cover 31 is arranged in a foldable manner. One end of the flexible cover 31 is fixedly connected to the upper end of the cover body 3, and the other end is fixedly connected to the outer wall of the output cylinder 21 to seal the gap between the cover body 3 and the output cylinder 21. Since the position of the cover body 3 relative to the output cylinder 21 changes during lifting and lowering, in order to close the gap between the cover body 3 and the output cylinder 21 and prevent dust from leaking from there, the flexible cover 31 is provided, which not only meets the movement requirements of the cover body 3, but also can seal the cover body 3, with a simple structure and convenient use. The flexible cover 31 can be a dustproof cloth or a leather cloth.

[0021] Please refer to Figure 1 The lithium battery material unloading and packaging device 100 also includes a screw feeder 7, which is arranged on the hopper 2 to quantitatively convey the lithium battery material into the hopper 2. By controlling the feeding amount of the screw feeder 7, the material is pre-stored in the hopper 2, and the barrel 4 can perform bag change operation at any time, which greatly reduces the unloading time and improves the unloading efficiency. Specifically, the screw feeder 7 includes a servo motor 71, a screw 72 and a feeding pipeline 73, and the servo motor 71 is electrically connected to the control system. An inlet 731 is provided at one end of the feeding pipeline 73, and an outlet 732 is provided at the other end, and the outlet 732 is connected to the hopper 2; the screw 72 is coaxially arranged in the feeding pipeline 73 and one end is connected to the output shaft of the servo motor 71 to convey the material of the inlet 731 to the outlet 732. By using the servo motor 71 to control the number of revolutions of the screw 72, the amount of material discharged into the hopper 2 can be accurately controlled, so that the material can be delivered to the packaging bag 200 at one time, greatly reducing the time for a single discharge and improving production efficiency.

[0022] Please refer to Figure 1, the outer side of the cover body 3 is connected to the movable bracket 8, and the movable bracket 8 can be moved up and down relative to the fixed bracket 1 by slidingly connecting to the guide rod 81 on the fixed bracket 1. One end of the lifting mechanism 5 is arranged on the fixed bracket 1, and the other end is connected to the movable bracket 8. Specifically, the lifting mechanism 5 is a cylinder. The cylinders are distributed on opposite sides of the cover body 3, and the synchronous extension and contraction of the two cylinders can drive the cover body 3 to rise or fall. In other embodiments, the lifting mechanism 5 can also be a motor-driven belt, and the belt drives the movable bracket 8 to rise and fall, which can also achieve similar functions. In addition, the lifting mechanism 5 can also drive the movable bracket 8 to rise or fall by driving the motor to drive the screw nut. For example, the motor is arranged on the fixed bracket 1, the nut is rotatably arranged on the fixed bracket 1, one end of the screw is threadedly connected to the nut, and the other end of the screw is fixedly connected to the movable bracket 8, so that the screw can rise or fall, thereby driving the cover body 3 to rise and fall.

[0023] See also Figure 2 At least two opposite sides of the outer wall of the barrel 4 are provided with hooks 42, and when the packaging bag 200 is placed in the barrel 4, the handles of the packaging bag 200 are buckled on the hooks 42. The packaging bag 200 is positioned by the hooks 42, so that the packaging bag 200 can be prevented from being pulled and displaced by the material when the material is unloaded, and the material is ensured to fall into the packaging bag 200.

[0024] Please see again Figure 1 The side wall of the hopper 2 is provided with a through hole 22 communicating with the outside, and a filter device 9 is provided at the through hole 22. Since the fan 6 transports the gas mixed with dust and air into the hopper 2, the air pressure of the hopper 2 will increase. Therefore, by providing the through hole 22 and arranging the filter device 9 on the through hole 22, the dust can be filtered into the hopper 2, and the clean gas is discharged from the hopper 2 after filtering, which will not affect the surrounding environment.

[0025] Please see again Figure 1The lithium battery material unloading and packaging device 100 also includes a guide rail 10, which extends outward from the bottom of the cover body 3. The end of the guide rail 10 close to the bottom of the cover body 3 is provided with a positioning member 101 for positioning the barrel 4. The bottom surface of the barrel 4 is provided with a moving trolley or roller 43, so that the barrel 4 is movably arranged on the guide rail 10. The barrel 4 can be easily moved out of the cover body 3 by using the guide rail 10 to guide the barrel 4, so as to facilitate the replacement of the packaging bag 200 and improve the convenience of unloading. The positioning member 101 of this embodiment can be a positioning reference to limit the position of the barrel 4 so that it can be accurately docked with the cover body 3. The positioning member 101 can also be a positioning block, which is pushed into or out of the guide rail 10 by a cylinder, so that the barrel 4 is fixed below the cover body 3.

[0026] Combining the above and Figure 3 The working principle of the lithium battery material unloading and packaging device 100 of the present invention is described in detail as follows:

[0027] When unloading, the lithium battery material is transported from the reaction furnace to the inlet 731 of the screw feeder 7. At this time, the control system controls the screw feeder 7 to start and transport the lithium battery material to the hopper 2. At this time, the control valve 22 is in a closed state, and the lithium battery material is temporarily stored in the hopper 2. After the quantitative feeding is completed, the screw feeder 7 stops. At the same time, the worker can place the packaging bag 200 in the barrel 4, so that the edge of the bag mouth of the packaging bag 200 turns over the cushion pad 41 covering the material root and buckles the lifting ear on the hook 42 on the outside of the barrel 4. At this time, the barrel 4 can be pushed to the bottom of the cover 3 and positioned by the positioning member. Then, the control system controls the lifting mechanism 5 to start, thereby pushing the movable bracket 8 to move downward, and the movable bracket 8 drives the cover 3 to descend toward the barrel 4. Finally, the cover body 3 is placed on the barrel 4, and the inner side wall of the cover body 3 is against the buffer pad 41, and the cover body 3 and the buffer pad 41 clamp the bag opening of the packaging bag 200 together. After that, the control system controls the control valve 22 to open, so that the lithium battery material in the hopper 2 falls into the packaging bag 200 through the output tube 21. After the unloading is completed, the control system controls the control valve 22 to close, and at the same time, the fan 6 is started, and the fan 6 draws the dust raised in the cover body 3 and the packaging bag 200 back into the hopper 2. After the dust collection is completed, the lifting mechanism 5 drives the cover body 3 to rise and open the barrel 4. At this time, the barrel 4 can be pulled out, and the packaging bag 200 can be sealed and packaged. At the same time, a new packaging bag 200 can be loaded into the barrel 4 to prepare for the next unloading operation. When the packaging bag 200 is sealed, the control system controls the screw feeder 7 to start feeding the hopper 2 again, so as to prepare for the next feeding operation. Similarly, the packaging can be continuously performed.

[0028] Compared with the prior art, the present invention provides a relatively sliding cover body 3 on the output tube 21 of the hopper 2, and provides a barrel 4 for positioning the packaging bag 200 below the cover body 3, and provides a buffer pad 41 at the opening edge of the barrel 4, and uses a lifting mechanism 5 to drive the cover body 3 to rise or fall, so that the inner side wall of the cover body 3 can be pressed against the buffer pad 41 at the edge of the barrel 4; at the same time, the opening of the packaging bag 200 on the edge of the barrel 4 will also be clamped and fixed by the buffer pad 41 and the cover body 3, so that the cover body 3 and the inside of the packaging bag 200 form a closed space, and when the hopper 2 is unloading, the raised dust can be prevented from leaking to the outside. In addition, by using the fan 6 connected to the cover body 3 to suck away the dust in time, the inside of the cover body 3 can be quickly purified, and there is no need to wait for the dust to settle before removing the barrel 4, and the unloading speed is fast. In addition, by connecting the output end of the fan 6 to the hopper 2, the dust sucked away can flow back into the hopper 2 and be re-loaded, which not only avoids material waste, but also eliminates the need for additional dust treatment, and is simple and practical. In summary, the present invention can prevent dust from leaking into the external environment during unloading and packaging, reduce air pollution, effectively improve the production environment, and has high unloading efficiency.

[0029] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the scope of the patent application of the present invention still fall within the scope covered by the present invention.
