Description

Technical Field

[0001] This utility model relates to the field of mixing technology, and more specifically, to a mixing and blending device for lithium battery binders. Background Technology

[0002] Traditional mixing devices typically employ fixed mixing torque and speed. When changes occur during production or the raw material ratios need adjustment, complex manual adjustments are often required. This method is not only time-consuming and labor-intensive but also prone to inaccurate or incorrect adjustments, leading to uneven mixing and affecting the quality of the final product. In traditional devices, adjusting the mixing torque usually relies on mechanical devices or manual operation, making the adjustment process extremely cumbersome, especially during production when frequent adjustments to the mixing intensity are necessary. Furthermore, traditional adjustment methods lack real-time feedback, preventing operators from promptly understanding changes in mixing torque and their effects, thus increasing the risk of errors.

[0003] Existing equipment often cannot flexibly adapt to the production requirements of different batches and materials. Especially when dealing with high-viscosity or low-viscosity materials, traditional adjustment mechanisms cannot provide sufficient flexibility to cope with different mixing needs. Excessive or insufficient mixing force may lead to poor material dispersibility, affecting the mixing effect and the consistency of the final product. Utility Model Content

[0012] The present invention is further configured such that a rubber ring is installed at the bottom end of the side wall of the clamping tube, and one end of the longitudinal pressure ring can contact the top end of the rubber ring, thereby reducing friction and extending the service life of the clamping tube.

[0013] The present invention is further configured such that a discharge hopper is connected to the bottom end of the mixing tank, and a sealing plate is slidably installed on the discharge hopper. The design of the discharge hopper and the sealing plate ensures that the material at the bottom of the mixing tank can be discharged in a timely manner, avoiding accumulation and waste.

[0014] The present invention is further configured such that a second liquid cylinder is installed at the bottom end of the mixing tank, and one end of the second liquid cylinder is connected to the sealing plate. The second liquid cylinder is used to precisely control the movement of the sealing plate and can ensure the sealing state of the sealing plate when discharging materials.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, the present invention provides a lithium battery binder mixing and stirring device, which has the following beneficial effects:

[0017] This invention features a stirring mechanism that drives a rotating shaft via a drive motor and mounting sleeve, thereby causing the stirring blades to mix efficiently.

[0029] Please see Figures 1-5 A lithium battery binder mixing and blending device includes a mixing tank 1, a mixing mechanism, a torque clamping mechanism, and a clamping auxiliary mechanism. The mixing mechanism includes a drive motor 2 and a mounting sleeve 3. The drive motor 2 is mounted on the side of the mixing tank 1. The mixing tank 1 is rotatably supported by a rotating shaft 4. The mounting sleeve 3 is mounted on the rotating shaft 4 and a mixing blade 5 is mounted on the mounting sleeve 3. The torque clamping mechanism includes a torque rod 6, a clamping tube 7, and a horizontal insertion rod 8. Multiple sets of torque rods 6 are installed between the mixing blade 5 and the mounting sleeve 3. The torque rods 6 have adjustment... The joint hole 9 has multiple sets of adjustment holes 9. One end of the horizontal insertion rod 8 can extend into different adjustment holes 9 to pass through multiple sets of torque rods 6. Both ends of the horizontal insertion rod 8 extend into the clamping tube 7 for engagement. The clamping tube 7 is set to contact the side of a set of torque rods 6 to fix the horizontal insertion rod 8 on the torque rod 6. Embedding grooves 10 are opened on the side walls of both ends of the horizontal insertion rod. A rotating plate 11 is rotatably installed on the side wall of the clamping tube 7. An embedding ball 12 is installed on one end of the rotating plate 11. The embedding ball 12 is embedded into the embedding groove 10 to fix the horizontal insertion rod 8 in the clamping tube 7.

[0030] In this embodiment, the stirring mechanism is powered by the drive motor 2 to achieve the stirring function. During operation, the drive motor 2 starts and drives the rotating shaft 4 to rotate. The mounting sleeve 3 installed on the rotating shaft 4 rotates accordingly. The stirring blade 5 on the mounting sleeve 3 rotates in the stirring tank 1 to mix and stir the lithium battery binder. The rotating shaft 4 is supported at the upper limit of the stirring tank 1 to ensure that the stirring process is stable and reliable. The torque clamping mechanism is used to adjust the stirring force and connect the stirring components. First, multiple sets of torque rods 6 are installed between the stirring blade 5 and the mounting sleeve 3. Multiple sets of adjustment holes 9 are provided on the torque rods 6. According to the required stirring force, the appropriate adjustment hole 9 position is selected, and the horizontal insertion rod 8 is passed through the corresponding adjustment hole 9 of the torque rod 6. The two ends of the horizontal insertion rod 8 extend into the clamping tube 7. The clamping tube 7 contacts the side of the torque rod 6. The rotating plate 11 inside the clamping tube 7 rotates, and the embedded ball 12 at the end of the rotating plate 11 is embedded into the embedded groove 10 on the side wall of the horizontal insertion rod 8, thus firmly fixing the horizontal insertion rod 8 in the clamping tube 7, completing the connection and torque adjustment.

[0031] The snap-fit ​​auxiliary mechanism includes an outer rotating ring 13 and a longitudinal pressure ring 14. The outer rotating ring 13 is rotatably mounted on the outer wall of the snap-fit ​​tube 7, and the longitudinal pressure ring 14 is slidably mounted on the outer wall of the snap-fit ​​tube 7. The longitudinal pressure ring 14 presses against the rotating plate 11, causing the rotating plate 11 to embed inward. A spiral plate 15 is installed at the bottom end of the outer rotating ring 13, and a longitudinal moving tube 16 is installed at the top end of the longitudinal pressure ring 14. A spiral groove 17 is opened on the longitudinal moving tube 16. The spiral groove 17 and the spiral plate 15 are screwed and slidably connected. The rotation of the spiral plate 15 causes the longitudinal pressure ring 14 to move longitudinally.

[0032] In this embodiment, the snap-fit ​​auxiliary mechanism provides precise control for the snap-fit ​​process. The outer rotating ring 13 is limited to rotate and is installed on the outer wall of the snap-fit ​​tube 7. The longitudinal pressure ring 14 is longitudinally slidably installed on the outer wall of the snap-fit ​​tube 7. When the outer rotating ring 13 is rotated, the bottom spiral plate 15 cooperates with the spiral groove 17 on the longitudinal moving tube 16 to convert the rotational motion into the longitudinal movement of the longitudinal pressure ring 14. When the longitudinal pressure ring 14 moves down, it presses against the rotating plate 11, causing the rotating plate 11 to embed inward. The embedding ball 12 is more firmly embedded in the embedding groove 10 of the horizontal insertion rod 8. When the longitudinal pressure ring 14 moves up, it reduces the pressure on the rotating plate 11, making it easier for the rotating plate 11 to be in the released state, so that the snap-fit ​​tube 7 and the horizontal insertion rod 8 are separated, realizing reliable locking and quick unlocking of the snap-fit ​​mechanism.

[0033] Please see Figures 1-5As a supplementary embodiment of a lithium battery binder mixing and blending device with a stirring mechanism, a torque clamping mechanism, and a clamping auxiliary mechanism: A main frame 18 is installed at the bottom of the mixing tank 1, and the main frame 18 is in contact with the ground. A flip cover 19 is rotatably installed on the side of the mixing tank 1. A first liquid cylinder 20 is rotatably installed between the side of the flip cover 19 and the side of the mixing tank 1. A rotating groove 21 is opened on the side wall of the clamping pipe 7. A rotating plate 11 is rotatably installed in the rotating groove 21. A rubber ring 22 is installed at the bottom of the side wall of the clamping pipe 7. One end of the longitudinal pressure ring 14 can contact the top end of the rubber ring 22. A discharge hopper 23 is connected to the bottom of the mixing tank 1. A sealing plate 24 is slidably installed on the discharge hopper 23. A second liquid cylinder 25 is installed at the bottom of the mixing tank 1, and one end of the second liquid cylinder 25 is connected to the sealing plate 24.

[0034] More specifically, open the flip-top cover 19 on the side of the mixing tank 1, add lithium battery binder raw materials into the mixing tank 1, close the flip-top cover 19, adjust the stirring force through the torque clamping mechanism according to the characteristics of the binder material and the stirring requirements, select the appropriate position of the torque rod 6 adjustment hole 9, insert the horizontal insertion rod 8, and fix it with the clamping mechanism and clamping auxiliary mechanism. Start the drive motor 2 to drive the rotating shaft 4, the mounting sleeve 3 and the stirring blade 5 to rotate, mix and stir the binder in the tank. After the stirring is completed, start the second liquid cylinder 25, push the sealing plate 24 to slide open, and let the mixed binder be discharged through the discharge hopper 23 at the bottom of the mixing tank 1. After emptying, the flip-top cover 19 can be opened again to clean the inside of the mixing tank 1 and the stirring blade 5, and prepare for the next batch of production.

[0035] In summary, when the overall equipment is in use or running: when the stirring mechanism needs to run, the stirring mechanism is powered by the drive motor 2 to achieve the stirring function. During operation, the drive motor 2 starts and drives the rotating shaft 4 to rotate. The mounting sleeve 3 installed on the rotating shaft 4 rotates accordingly. The stirring blades 5 on the mounting sleeve 3 rotate inside the mixing tank 1 to mix and stir the lithium battery binder. The rotating shaft 4 is supported at the upper limit of the mixing tank 1 to ensure that the stirring process is stable and reliable.

[0036] When the torque clamping mechanism is required to operate, it is used to adjust the stirring force and connect the stirring components. First, multiple sets of torque rods 6 are installed between the stirring blade 5 and the mounting sleeve 3. Multiple sets of adjustment holes 9 are provided on the torque rods 6. According to the required stirring force, the appropriate position of the adjustment hole 9 is selected, and the horizontal insertion rod 8 is passed through the corresponding adjustment hole 9 of the torque rod 6. The two ends of the horizontal insertion rod 8 extend into the clamping tube 7. The clamping tube 7 contacts the side of the torque rod 6. The rotating plate 11 inside the clamping tube 7 rotates, and the embedded ball 12 at the end of the rotating plate 11 is embedded into the embedded groove 10 on the side wall of the horizontal insertion rod 8, thus firmly fixing the horizontal insertion rod 8 in the clamping tube 7, completing the connection and torque adjustment.

[0037] When the locking auxiliary mechanism is required to operate, it provides precise control for the locking process. The outer rotating ring 13 is limited to rotating and installed on the outer wall of the locking tube 7, and the longitudinal pressure ring 14 is longitudinally slidably installed on the outer wall of the locking tube 7. When the outer rotating ring 13 is rotated, the bottom spiral plate 15 cooperates with the spiral groove 17 on the longitudinal moving tube 16 to convert the rotational motion into the longitudinal movement of the longitudinal pressure ring 14. When the longitudinal pressure ring 14 moves down, it presses against the rotating plate 11, causing the rotating plate 11 to embed inward. The embedding ball 12 is more firmly embedded in the embedding groove 10 of the horizontal insertion rod 8. When the longitudinal pressure ring 14 moves up, it reduces the pressure on the rotating plate 11, making it easier for the rotating plate 11 to be in the release state, so that the locking tube 7 and the horizontal insertion rod 8 are separated, realizing reliable locking and quick unlocking of the locking mechanism.

[0038] Open the flip-top cover 19 on the side of the mixing tank 1, add lithium battery binder raw material into the mixing tank 1, close the flip-top cover 19, adjust the stirring force through the torque clamping mechanism according to the characteristics of the binder material and the stirring requirements, select the appropriate position of the torque rod 6 adjustment hole 9, insert the horizontal insertion rod 8, and fix it with the clamping mechanism and clamping auxiliary mechanism, start the drive motor 2, drive the rotating shaft 4, the mounting sleeve 3 and the stirring blade 5 to rotate, mix and stir the binder in the tank, after the stirring is completed, start the second liquid cylinder 25, push the sealing plate 24 to slide open, so that the mixed binder is discharged through the discharge hopper 23 at the bottom of the mixing tank 1. After emptying, the flip-top cover 19 can be opened again to clean the inside of the mixing tank 1 and the stirring blade 5, and prepare for the next batch of production.
