[0018] Working principle: When in use, place the stirring device on the stirring platform 1, and drive the whole equipment to move through the moving wheel 2 at the bottom. The vibration acts on the vibration-damping protective bag 3 604. After the vibration-damping protective bag 3 604 is subjected to pressure, the gas inside it is discharged through the force-unloading air hole 605 to form a preliminary buffer. The shaking impact force continues to act on the vibration-damping protective bag 2 603. After the vibration-damping protective bag 2 603 is subjected to pressure, the gas inside it is discharged through the force-unloading air hole 605 to form a secondary buffer. The shaking impact force continues to act on the vibration-damping protective bag 1 602. After the vibration-damping protective bag 1 602 is subjected to pressure, the gas inside it is discharged through the force-unloading air hole 605 to form a further buffer, which greatly reduces the impact force caused by the shaking. The damping bracket 6 06 moves toward the mixing platform 1 under the action of the shaking impact force, and the damping plate 607 exerts pressure on the vibration reduction spring 608, which cooperates with the elastic effect of the vibration reduction spring 608 to form a certain degree of vibration reduction buffering, and the buffering protection effect is good, which reduces the influence of the shaking force on the stirring device on the mixing platform 1 and improves the stirring efficiency of the stirring device. After the shaking occurs, the vibration reduction front stopper 601 generates an impact force on the I-shaped frame 701, and the I-shaped frame 701 generates a backward thrust to push the vibration reduction seat 702 and the inner rack plate 708 to move toward the side of the mixing platform 1. When the vibration reduction seat 702 moves backward, the side of the guide plate 705 close to the vibration reduction seat 702 rotates toward the side of the mixing platform 1, and at the same time, the clamping frame 703 moves along the front wall of the mixing platform 1 through the positioning slider and the positioning slot 704 The two clamping frames 703 slide and approach each other, so that the outer limit frame 706 fits with the inner limit frame 707, and the arc-surface protrusions 714 on the surfaces of the outer limit frame 706 and the inner limit frame 707 generate mutual friction, which limits the I-frame 701 from continuing to move backward to a certain extent, forming a reverse impulse, and the reverse impulse and the impact force offset each other, reducing the impact caused by the shaking, and the inner rack plate 708 meshes with the linkage gear 709. During the movement of the inner rack plate 708, the linkage gear 709 rotates accordingly, and the linkage gear 709 meshes with the outer rack plate 710. The I-frame 701 moves forward with the rotation of the linkage gear 709, so that the anti-impact airbag 712 is against the surface of the vibration-damping front stopper 601, which offsets the impact force again and forms a shaking. The reverse impact force of the shaking object acts on the shaking object through the vibration reduction buffer component 6 to form a reverse rebound force. The reverse rebound force induces the shaking object to separate from the mixing platform 1 to prevent the mixing platform 1 from falling into the shaking object. When the inner rack plate 708 moves backward under the action of the shaking force, the driving gear 801 rotates with the rotation of the linkage gear 709, the driving gear 801 is meshed with the synchronous toothed belt 802, and the driven gear 803 is meshed with the synchronous toothed belt 802. The driving gear 801 and the driven gear 803 realize synchronous rotation. After the driven gear 803 rotates, the anti-vibration bracket 805 drives the anti-vibration splint 806 to rotate to one side of the mixing platform 1, and the anti-vibration splint 806 produces pressure on the stirring device of the mixing platform 1.The stirring device is made more stable on the stirring platform 1, and the stirring device is prevented from falling off the stirring platform 1 due to shaking force, and the stirring device is prevented from being damaged, and the stirring efficiency of the stirring device is improved, and the durability of the stirring device is improved.

[0019] (III) Beneficial effects

[0020] The present invention provides a raw material mixing device for lithium ion battery production, which has the following beneficial effects:

[0021] 1. The present invention has the effects of reducing the impact force caused by shaking and forming vibration reduction and buffering protection, reducing losses, increasing stirring speed and efficiency, and improving the durability and stability of the device;

[0022] 2. The present invention forms a buffer protection for the stirring platform and the stirring device loaded thereon through the vibration-damping buffer component.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Example:

[0033] Reference Figure 1-Figure 7 A raw material mixing device for lithium-ion battery production includes a stirring platform 1, wherein moving wheels 2 are fixedly connected at the four corners of the bottom of the stirring platform 1, and a receiving frame 3 is fixedly connected to the top wall of one side of the stirring platform 1, and a receiving rod 4 is fixedly connected to the outer wall of the receiving frame 3, and a protective shell 5 is fixedly connected to the top wall of the stirring platform 1 away from the receiving frame 3. A vibration damping and buffering component 6 is arranged on the outer wall of the stirring platform 1, and the vibration damping and buffering component 6 is arranged at the front end of the stirring platform 1, and an anti-impact component 7 is arranged on the vibration damping and buffering component 6, and the anti-impact component 7 is arranged between the protective shell 5 and the vibration damping and buffering component 6, and an anti-vibration limiting component 8 is arranged on the anti-impact component 7.

[0034] The stirring device is placed on the stirring platform 1, and the whole equipment is driven to move by the moving wheel 2 at the bottom. When the stirring platform 1 is affected by shaking during the stirring process, the vibration-damping buffer component 6 forms a buffer protection for the stirring platform 1 and the stirring device loaded thereon. The vibration-damping buffer component 6 generates pressure on the anti-impact component 7. The anti-impact component 7 limits the vibration-damping buffer component 6 to reduce the reverse impact force caused by the shaking, form anti-impact vibration reduction, and generate the effect of force in the opposite direction to the shaking. The anti-vibration limiting component 8 stabilizes the stirring device loaded on the stirring platform 1 to prevent the stirring device from falling due to the shaking, so as to facilitate continued stirring and improve stirring efficiency.

[0035] The vibration damping and buffering component 6 includes a vibration damping front stopper 601, which is fixedly connected to the front end outer wall of the mixing platform 1, and a vibration damping protection capsule 1 602 is fixedly connected to the outer wall of the vibration damping front stopper 601 away from the mixing platform 1, and a plurality of vibration damping protection capsules 2 603 are fixedly connected to the outer wall of the vibration damping protection capsule 1 602 away from the vibration damping front stopper 601, and a plurality of vibration damping protection capsules 3 604 are fixedly connected to the outer wall of the vibration damping protection capsule 2 603 away from the vibration damping protection capsule 1 602.

[0036] When shaking occurs during the stirring process, the shaking force acts on the vibration-damping protective bag three 604. After the vibration-damping protective bag three 604 is subjected to pressure, the gas inside it is discharged through the force unloading air hole 605 to form a preliminary buffer. The shaking impact force continues to act on the vibration-damping protective bag two 603. After the vibration-damping protective bag two 603 is subjected to pressure, the gas inside it is discharged through the force unloading air hole 605 to form a secondary buffer. The shaking impact force continues to act on the vibration-damping protective bag one 602. After the vibration-damping protective bag one 602 is subjected to pressure, the gas inside it is discharged through the force unloading air hole 605 to form a further buffer, thereby greatly reducing the impact force caused by the shaking. The damping bracket 606 moves toward the stirring platform 1 under the action of the shaking impact force, and the damping plate 607 produces pressure on the vibration-damping spring 608, which cooperates with the elastic effect of the vibration-damping spring 608 to form a certain degree of vibration-damping buffer, with good buffering protection effect, reducing the influence of the shaking force on the stirring device on the stirring platform 1, and improving the stirring efficiency of the stirring device.

[0037] The impact-resistant assembly 7 includes a work-shaped frame 701, the outer wall of the side of the work-shaped frame 701 away from the mixing platform 1 is fixedly connected to the outer wall of the side of the vibration-damping front stop 601 close to the mixing platform 1, and the outer wall of the side of the work-shaped frame 701 close to the mixing platform 1 is fixedly connected to a vibration-damping seat 702, and clamping frames 703 are symmetrically arranged on both sides of the vibration-damping seat 702.

The anti-impact airbag 712 is provided on the side of the vibration-damping front bumper 601.

[0038] After the shaking occurs, the vibration-damping front stopper 601 generates an impact force on the I-shaped frame 701, and the I-shaped frame 701 generates a backward thrust to push the vibration-damping seat 702 and the inner rack plate 708 to move toward the side of the mixing platform 1. When the vibration-damping seat 702 moves backward, the side of the guide plate 705 close to the vibration-damping seat 702 rotates toward the side of the mixing platform 1.

The reverse impulse and the impact The forces offset each other, reducing the impact of shaking, the inner rack plate 708 is meshed with the linkage gear 709, and during the movement of the inner rack plate 708, the linkage gear 709 rotates accordingly, and the linkage gear 709 is meshed with the outer rack plate 710. The I-frame 701 moves forward with the rotation of the linkage gear 709, so that the anti-impact airbag 712 is offset against the surface of the shock-absorbing front stop 601, offsetting the impact force again, and forming a reverse impact force toward the shaking animal. The reverse impact force acts on the shaking animal through the shock-absorbing buffer assembly 6, forming a reverse rebound force. The reverse rebound force induces the shaking animal to separate from the stirring platform 1, avoiding the stirring platform 1 from sinking into the shaking animal, making it easier to continue stirring the stirring device, thereby improving the stirring efficiency of the stirring device.
