Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] See also Figure 1-3The utility model provides a technical solution: a trough device for feeding a lithium-ion battery coating machine, including a trough body 1, the trough body 1 is composed of an arc portion 101 and a horizontal portion 102, the horizontal portion 102 is located at the bottom of the arc portion 101, and the two constitute an integral main structure of the trough body 1, the design of the arc portion 101 can help the slurry flow more smoothly, reduce dead angles, and avoid accumulation of slurry in certain areas to cause unevenness or bubble formation, the horizontal portion 102 is the bottom of the trough body 1, which can ensure that the slurry can be evenly distributed in the trough body 1, which is beneficial to the subsequent coating process, and the inner walls on both sides of the arc portion 101 are provided with an oscillation plate 2, and both sides of the oscillation plate 2 are connected with a connector 6, which is an L-shaped structure. The outer ends of the same group of connecting parts 6 are commonly connected with connecting plates 5, and a vibrator 7 is fixedly installed in the middle of the top of the connecting plate 5 by screws, and the bottom of the outer end of the connecting part 6 is provided with a support rod 8 that is movably connected to the outer wall of the trough body 1. The connection between the support rod 8 and the connecting part 6 is connected and installed by a sleeve and a bolt. After the vibrator 7 of this structure is started, it will drive the connecting plate 5 to vibrate, and then drive the oscillation plate 2 to vibrate inside the trough body 1 through the connecting part 6, further effectively improving the fluidity of the slurry, reducing the formation of dead angles, ensuring the uniformity of the discharge, and simplifying the cleaning process, improving the production efficiency and reliability of the equipment. Positioning sleeves 10 are symmetrically provided on the outer walls of both sides of the trough body 1, and the bottom ends of the support rods 8 are slidably inserted into the interior of the positioning sleeves 10, and the outer The sleeve is provided with a supporting spring 11. The support rod 8 of this structure will slide inside the positioning sleeve 10 as the vibration plate 2 moves. The supporting spring 11 plays the role of buffering and resetting, ensuring that the vibration plate 2 can move smoothly during the vibration process and quickly return to the initial position after each vibration. This not only improves the fluidity of the slurry, reduces the formation of dead angles, and ensures the uniformity of discharging, but also enhances the stability and reliability of the system through the sliding cooperation between the support rod 8 and the positioning sleeve 10 and the elastic effect of the supporting spring 11. The top walls of the edges on both sides of the trough body 1 are bonded and fixed with elastic pads 9. The elastic pads 9 are made of elastic rubber material with good elasticity and durability, and the top of the elastic pad 9 fits in with the corresponding position of the bottom of the connecting plate 5. The bottom of the connecting plate 5 of this structure It will periodically contact the elastic support pad 9, which can absorb part of the vibration energy, reduce the impact of the connecting plate 5, and ensure the smooth vibration of the connecting plate 5 and the oscillation plate 2. The surface of the oscillation plate 2 is evenly provided with a number of guide grooves 3 with arc-shaped inner walls, and a number of overflow holes 4 are evenly provided on the horizontal part 102.

When the vibration plate 2 needs to be installed, this structure can be installed by pulling the pull block 14 to move the pressure shaft 13 outward, compressing the spring 15, and the card block 12 moves accordingly, so that the card block 12 can be smoothly inserted into the card slot of the vibration plate 2, and after releasing the pull block 14, the spring 15 returns to its original state, pushing the card block 12 to be fastened in the card slot, thereby completing the installation of the vibration plate 2. When the vibration plate 2 needs to be disassembled, it is only necessary to pull the pull block 14 again to make the card block 12 disengage from the card slot and the vibration plate 2 can be easily removed. This not only simplifies the installation and disassembly process of the vibration plate 2, but also improves the convenience of maintenance and cleaning. ,

[0018] Working principle: When using the trough device for feeding the lithium-ion battery coating machine, first add the slurry into the trough body 1 composed of the arc part 101 and the horizontal part 102. After the vibrator 7 is started, it will drive the connecting plate 5 to vibrate, and then drive the vibration plate 2 to vibrate inside the trough body 1 through the connecting piece 6. The vibration of the vibration plate 2 improves the fluidity of the slurry and reduces the formation of dead angles. The support rod 8 will slide inside the positioning sleeve 10 with the movement of the vibration plate 2. The support spring 11 plays a role of buffering and resetting, and quickly returns to the initial position after each vibration. The bottom of the connecting plate 5 will periodically contact the elastic support pad 9, which can absorb part of the vibration energy and reduce the vibration of the connecting plate 5. The guide groove 3 on the surface of the oscillation plate 2 helps to guide the slurry to flow in a specific direction, reducing the stagnation of the slurry inside the trough body 1. The overflow hole 4 on the horizontal part 102 is designed to cause the slurry to form a small vortex flow, which helps to further evenly disperse the slurry and ensure the uniform distribution of the slurry in the trough body 1, thereby improving the uniformity and consistency of the discharge. When the oscillation plate 2 needs to be installed or removed, the pressure shaft 13 is moved outward by pulling the pull block 14, and the spring 15 is compressed, and the card block 12 moves accordingly, so that the card block 12 can be smoothly inserted into or out of the slot of the oscillation plate 2, completing the rapid installation or removal of the oscillation plate 2, thereby completing a series of tasks.
