Description

Technical Field

[0001] This invention relates to the field of phenolic resin pre-curing equipment technology, and in particular to a pre-curing device based on phenolic resin lithium battery anode material. Background Technology

[0002] During the pre-curing process of phenolic resin, additives are sprayed onto the flocculent material. Generally, the atomizing nozzles inside the cylinder are located on the cylinder wall, and the stirring blades inside the cylinder are multi-segmented. In order to avoid the atomizing nozzles, the multi-segmented stirring blades will create dead zones when stirring the material, resulting in uneven stirring. At the same time, the pressure inside the atomizing nozzle is insufficient when preparing to spray the additives or after spraying. This causes the additives to flow down along the spray nozzle and form water droplets. The water droplets of additives cause the material inside the main cylinder to stick together, affecting the pre-curing effect of the material. Summary of the Invention

[0003] To overcome the shortcomings of the prior art, this invention discloses a pre-curing device for phenolic resin lithium battery negative electrode materials. The spraying mechanism of this invention is located on the main rod of the stirring mechanism, making the stirring blades of the stirring mechanism an integrated structure, avoiding dead zones during the stirring process. The spraying mechanism sprays additives onto the material inside the main cylinder.

[0023] Combined with appendix Figures 1-4 The aforementioned pre-curing device for phenolic resin lithium battery negative electrode material includes a main cylinder 1, a stirring mechanism 2 installed inside the main cylinder 1, a feed inlet and a discharge outlet on the main cylinder 1, both of which are equipped with closing caps, and a spraying mechanism 3 installed on the rotating end of the stirring mechanism 2. A liquid supply pipe 4 is installed on the feed end of the spraying mechanism 3. The material being stirred inside the main cylinder 1 is sprayed through the spraying mechanism 3, while preventing residual liquid in the spraying end of the spraying mechanism 3 from dripping into the main cylinder 1 before or after spraying. All electrical equipment used in this invention is electrically connected to an external control device, and the operation of the electrical equipment used in this invention is controlled by the external control device.

[0024] The stirring mechanism 2 includes a main rod 201, stirring blades 202, driving rods 203, a gear ring 204, and a servo motor. The main rod 201 is located on the main cylinder 1 and rotatably connected, and the gear ring 204 is fixedly connected to one end of the main rod 201 outside the main cylinder 1. The servo motor is located on the main cylinder 1 and fixedly connected, and the servo motor is connected to a motor gear through a motor shaft. The position of the motor gear corresponds to the position of the gear ring 204 and they are meshed. The driving rods 203, which are arranged at equal intervals, are fixedly connected to the rod wall inside the main cylinder 1, and the stirring blades 202 are fixedly connected to the driving rods 203.

[0025] The main body rod 201 is provided with a liquid supply groove, and the main body rod 201 is provided with mounting grooves arranged at equal intervals.

[0026] A drain trough is provided between the mounting slots, and the drain trough is connected to the mounting slot. The drain trough is used to collect the residual droplets on the atomizing nozzle 310.

[0027] The spraying mechanism 3 includes an electric telescopic rod 301, a sealed bearing 302, a transmission rod 303, a rotating ring 304, a push plate 305, a connecting plate 306, a rotating ring 307, a sleeve 308, a rotating block 309, and an atomizing nozzle 310. There are two electric telescopic rods 301, both located on the main body cylinder 1 and fixedly connected. A connecting plate 306 is fixedly connected to the telescopic end of each electric telescopic rod 301. A push plate 305 is fixedly connected between the two connecting plates 306, and a rotating ring 304 is rotatably connected to the push plate 305. A transmission rod 303 is fixedly connected to the upper part, and a rotating ring 307 is slidably connected to the transmission rod 303. Sealing bearings 302 are fixedly connected to the two side ring walls of the rotating ring 307, and the fixed end of the sealing bearing 302 is located in the liquid supply tank and fixedly connected. Sleeves 308 are equidistantly arranged on the main body rod 201 and rotatably connected. The position of the sleeves 308 corresponds to the position of the mounting groove. A rotating block 309 is fixedly connected to the sleeve 308, and an atomizing nozzle 310 is installed in the rotating block 309. The position of the sleeves 308 corresponds to the position of the transmission rod 303 and is slidably connected.

[0028] The transmission rod 303 is provided with a spiral protrusion, and the inner wall of the sleeve 308 is provided with a spiral groove. The position of the spiral groove corresponds to the position of the spiral protrusion and is slidably connected. The transmission rod 303 drives the sleeve 308 to rotate through the spiral protrusion. The rotation of the sleeve 308 adjusts the orientation of the atomizing nozzle 310. The principle is the same as that of a hand-pushed frisbee.

[0029] The rotating block 309 is provided with a liquid supply tank, and the drain port of the liquid supply tank is connected to the liquid inlet of the atomizing nozzle 310.

[0030] The sleeve 308 is provided with a drain port, and the drain port of the sleeve 308 is connected to the inlet of the liquid supply tank inside the rotating block 309.

[0031] The transmission rod 303 is provided with a liquid inlet groove, and the liquid inlet of the liquid inlet groove is located outside the sleeve 308, while the liquid outlet of the liquid inlet groove is located inside the sleeve 308. Liquid is supplied to the liquid outlet of the sleeve 308 through the liquid inlet groove on the transmission rod 303.

[0032] A liquid supply pipe 4 is fixedly connected inside the liquid inlet of the rotating ring 307.

[0033] In the aforementioned phenolic resin lithium battery negative electrode material pre-curing device, during use, a servo motor drives the main body rod 201 to rotate via a motor gear. The rotation of the main body rod 201 drives the stirring blade 202 to rotate, stirring the material inside the main body cylinder 1. Liquid is supplied to the liquid supply tank inside the main body rod 201 via a liquid supply pipe 4. The additive supplied by the liquid supply pipe 4 is supplied to the drain port of the sleeve 308 via a liquid inlet on the transmission rod 303, allowing the additive to enter the atomizing nozzle 310. After spraying for a certain period, the extension and retraction of the electric telescopic rod 301 drives the push plate 305. The movement is achieved by pushing the transmission rod 303 via the push plate 305. The movement of the transmission rod 303 causes the sleeve 308 to rotate. The rotation of the sleeve 308 controls the orientation of the atomizing nozzle 310, preventing water droplets from the atomizing nozzle 310 from falling into the main cylinder 1 before spraying. When spraying is about to be completed, the transmission rod 303 adjusts the orientation of the atomizing nozzle 310, causing the atomizing nozzle 310 to retract into the main rod 201, preventing water droplets from the atomizing nozzle 310 from falling into the main cylinder 1 after spraying. The liquid dripping from the atomizing nozzle 310 will enter the installation groove, and the collected dripping liquid will be discharged through the drainage groove in the installation groove.
