Description

Technical Field

[0001] This utility model relates to the field of new energy battery manufacturing technology, and in particular to a vacuum feeding machine for new energy battery manufacturing. Background Technology

[0002] A vacuum feeder is an industrial device that uses the principle of vacuum to automatically transport materials. Its core function is to use the negative pressure generated by a vacuum pump to suck up bulk materials from the material source and transport them to the target location through pipelines.

[0003] Vacuum feeders play a crucial role in the manufacturing process of new energy batteries, especially lithium-ion batteries. In the manufacturing of new energy batteries, vacuum feeders can transport positive and negative electrode materials, electrolytes and separators, achieving efficient and precise feeding; at the same time, they can also prevent dust leakage, protect workers' health and improve the production environment.

[0004] The particle size range of new energy battery raw materials is usually wide, between 0.1 and 50 μm. Fine particles with a particle size of <10 μm are easily adsorbed on the inner wall of the pipe due to van der Waals forces or electrostatic effects, while coarse particles with a particle size of >20 μm are easily deposited at the bends of the pipe due to centrifugal force. After the material is deposited in the pipe, it is difficult to clean, and it is necessary to stop the machine and disassemble the pipe for cleaning, which affects production efficiency. Utility Model Content

[0005] Given that the aforementioned materials are difficult to clean after accumulating in the pipeline, requiring machine shutdown and pipeline disassembly for cleaning, which affects production efficiency, this utility model was proposed.

[0006] Therefore, the purpose of this utility model is to provide a vacuum feeding machine for manufacturing new energy batteries. By connecting components, the segmented pipes can be quickly disassembled or assembled, and the segmented pipes and the feeding pipes can be quickly assembled and adjusted according to actual needs, which improves the convenience of installation and transportation. After the entire pipeline is disassembled, the multiple segmented pipes can be cleaned, which improves the convenience of pipeline maintenance.

[0007] To solve the above technical problems, this utility model provides the following technical solution: a vacuum feeding machine for manufacturing new energy batteries, including a vacuum feeding machine body, the vacuum feeding machine body is connected to a plurality of segmented pipes, the segmented pipes are connected to a feeding pipe, the segmented pipes and the feeding pipe are provided with flanges, and the plurality of segmented pipes are provided with connecting components.

[0008] The connecting assembly includes a first clamp and a second clamp, which are rotatably connected. The first clamp has an installation groove, and a screw is rotatably connected to the installation groove. A nut is threaded onto the screw, which is integrally formed with a baffle. A spring is sleeved on the screw, with one end of the spring abutting against the baffle and the other end of the spring abutting against the nut. The second clamp has a limit groove.

[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0027] Example 1

[0028] Reference Figures 1-5This is the first embodiment of the present utility model, which provides a vacuum feeding machine for manufacturing new energy batteries, including a vacuum feeding machine body 1, a plurality of segmented pipes 2 connected to the vacuum feeding machine body 1, a feeding pipe 3 connected to the segmented pipes 2, a flange 4 provided on the segmented pipes 2 and the feeding pipe 3, and a connecting component 5 provided between the plurality of segmented pipes 2.

[0029] The connecting assembly 5 includes a first clamp 501 and a second clamp 502, which are rotatably connected. The first clamp 501 has an installation groove 503, and a screw 504 is rotatably connected to the installation groove 503. A nut 505 is threaded onto the screw 504. A baffle 506 is integrally formed on the screw 504. A spring 507 is sleeved on the screw 504. One end of the spring 507 abuts against the baffle 506, and the other end of the spring 507 abuts against the nut 505. The second clamp 502 has a limit groove 508.

[0030] Several flanges 4 are arranged in pairs with positioning grooves 6 on their opposite faces. A rubber gasket 7 is placed between two flanges 4, and the rubber gasket 7 is provided with positioning protrusions 8, which are located in the positioning grooves 6.

[0031] The first clamp 501 and the second clamp 502 are provided with receiving grooves 9, and the flange 4 and the rubber gasket 7 are located in the receiving grooves 9.

[0032] The feed pipe 3 consists of a stable section 301 and a contraction section 302.

[0033] Example 2

[0034] Reference Figures 1-5 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that: a mounting frame 10 is provided in the stable section 301 of the feed pipe 3, and an impeller 11 is rotatably connected to the mounting frame 10. The edge of the impeller 11 is provided with a blunt blade.

[0035] A ring 12 is provided in the stable section 301 of the feed pipe 3. The inner wall of the ring 12 is provided with teeth 13, and the teeth 13 are coaxially arranged with the impeller 11.

[0036] When in use, align the flanges 4 of multiple segmented pipes 2, or align the segmented pipes 2 with the flanges 4 of the feed pipe 3, place the rubber gasket 7 between the two flanges 4, and press the two flanges 4 together so that the positioning protrusion 8 is located in the positioning groove 6. The rubber gasket 7 is deformed by compression to fill the tiny gaps between the flanges 4, enhance the sealing effect, and prevent dust leakage. The length and number of segmented pipes 2 can be adjusted according to the actual layout.

[0037] Place the first clamp 501 and the second clamp 502 onto the flange 4 and surround it, ensuring that the flange 4 and the rubber gasket 7 are located in the receiving groove 9 to further improve the sealing effect. Then rotate the screw 504 so that the screw 504 lies in the mounting groove 503 and the limiting groove 508. Finally, tighten the nut 505 to complete the installation. When the conveying of materials causes the nut 505 to vibrate, the spring 507 provides thrust to prevent the nut 505 from loosening, thereby ensuring the stability of the connecting assembly 5 and preventing dust leakage.

[0038] When the vacuum feeder body 1 is working, it adsorbs materials through the feed pipe 3 and transports materials through the segmented pipe 2. When the high-speed airflow carries the materials through the feed pipe 3, the diameter of the constriction section 302 gradually decreases, which can increase the material flow rate. At the same time, the high-speed airflow drives the impeller 11 to rotate at high speed. The material clumps entering are impacted by the rotating impeller 11 and thrown to the surrounding teeth 13. Due to the shearing and impact, the material clumps are effectively broken up, which improves the smoothness of material flow.

[0039] The remaining structure is the same as that in Example 1.

[0040] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
