[0002] The anode of a lithium battery cell is coated or laminated with lithium-containing amorphous carbon powder on both sides of a copper foil, while the cathode is coated or laminated with lithium iron phosphate powder or nickel manganese cobalt phosphate powder on both sides of an aluminum foil. These powders are all mixtures. For example, the nickel manganese cobalt phosphate powder is actually a mixture of dry powders such as nickel powder, manganese powder, cobalt powder, flame retardant powder, and binder powder, all of which need to be stirred evenly.
[0003] Dry powder mixing requirements:
[0004] 1. Stir and disperse evenly.
[0005] 2. The mixture is flocculent.
[0006] To address this, we developed a satellite mixing device. Summary of the Invention
[0007] The purpose of this invention is to provide a satellite stirring device for uniformly dispersing and stirring powder.
[0008] The present invention is implemented as follows: a satellite mixing device includes a mixing bracket, a mixing transmission system, a mixing drive component, and a mixing mechanism. The mixing bracket and the mixing drive component are fixed on an external machine base, the mixing mechanism is mounted inside the mixing bracket, and the mixing transmission system is connected between the output end of the mixing drive component and the input end of the mixing mechanism.
[0009] The stirring mechanism includes two stirring paddles. The stirring drive unit drives the two stirring paddles of the stirring mechanism to revolve together through the stirring transmission system. The two stirring paddles rotate simultaneously, which can disperse and stir the powder evenly.
[0010] Furthermore, the stirring support includes a stirring base, a stirring shroud, end bushings, and three stirring support sealing rings. The stirring base includes a stirring support base plate, a stirring support upright plate, and a stirring support bracket. The stirring support base plate is fixed to an external machine base.

The stirring support bracket is fixed to the right side of the stirring support base plate. The stirring shroud is fixed to the stirring support upright plate with one open end, and the stirring shroud is fixed to the stirring support with its cylindrical body. On the support plate, the end bushing is dynamically matched with the outer end face of the end bushing and is fixed close to the top surface of the two stirring paddles to the other open end of the stirring hood. The left stirring bracket sealing ring is fixed in the sealing groove of the stirring bracket upright plate to the stirring hood to seal the left end of the stirring hood and the right side of the stirring bracket upright plate. The middle stirring bracket sealing ring is fixed in the sealing groove of the left end of the end bushing to seal the left end of the end bushing and the right end of the stirring hood. The right stirring bracket sealing ring is fixed in the outer sealing groove of the end bushing on the outer end face of the right end of the end bushing to seal the external stirring space.
[0011] Furthermore, the stirring mechanism includes a main shaft support assembly, a fixed gear, a main shaft assembly, a rotating drum assembly, an end sealing plate, an end sealing plate sealing strip, and two satellite stirring assemblies. The main shaft support assembly is fixed to the stirring support upright plate. The fixed gear is fixed to the end of the main shaft support assembly near the stirring support upright plate. The main shaft assembly is mounted inside the main shaft support assembly. The rotating drum assembly is fixed to the output end of the main shaft assembly. The end sealing plate is fixed to the rotating drum assembly with its left side facing out. The end sealing plate sealing strip is fixed in the end sealing plate sealing strip groove on the right side of the end sealing plate. The two satellite stirring assemblies are separately mounted inside the rotating drum assembly.

The sealing tape and the power input ends of the two satellite stirring groups are sealed inside the stirring hood. The end sealing plate sealing tape dynamically seals the end sealing plate and the left end face of the end bushing fixed to the stirring hood inside the stirring hood. The sealing of the satellite stirring device can prevent dust from entering the external stirring space and ensure the sealing of the external vacuum stirring space. The stirring drive unit drives the main shaft assembly together with the rotating drum assembly through the stirring transmission system, carrying the two satellite stirring groups to revolve around the center line of the main shaft assembly to stir the powder. At the same time, the two satellite stirring groups are driven by the rotating drum assembly and rotated by the fixed gear fixed on the main shaft support assembly to stir the powder. The stirring mechanism can disperse and stir the powder evenly.
[0012] Furthermore, the main shaft support assembly includes a main shaft support cylinder, a main shaft support cylinder end sealing ring, a rotary drum end cover, a rotary drum end cover wear-resistant sleeve, a rotary drum sealing ring, two rotary drum bearings, an inner ring support for the rotary drum bearings, an outer ring support for the rotary drum bearings, and a rotary drum bearing retaining ring. The main shaft support cylinder is aligned with the main shaft through hole of the stirring support upright plate and fixed to the stirring support upright plate with its left end flange. The main shaft support cylinder end sealing ring is fixed to the sealing joint between the left end flange of the main shaft support cylinder and the stirring support upright plate. The fixing gear is fixed to the main shaft support cylinder close to the right end face of the left end flange of the main shaft support cylinder. The rotary drum end cover passes through the main shaft support cylinder, is limited by the left end step of the main shaft support cylinder, and is fixed to the rotary drum assembly. The wear-resistant sleeve of the rotary drum end cover is disposed inside the rotary drum end cover to bear the rotational friction of the main shaft support cylinder. The rotary drum sealing ring is fixed in the sealing groove of the rotary drum end cover to seal the connection with the rotary drum assembly. The inner rings of the two rotary drum bearings pass through the outside of the main shaft support cylinder. The inner ring support of the rotary drum bearing passes through the outside of the main shaft support cylinder and is separated between the inner rings of the two rotary drum bearings to support the inner rings of the two rotary drum bearings. The outer ring support of the rotary drum bearing passes through the outer ring support of the inner ring of the rotary drum bearing and is separated between the outer rings of the two rotary drum bearings to support the outer rings of the two rotary drum bearings. The rotary drum bearing retaining ring is engaged in the retaining ring groove outside the right end of the main shaft support cylinder to limit the right end of the rotary drum bearing.
[0013] Furthermore, the main shaft assembly includes a main shaft and two main shaft bearings. The main shaft includes a central main shaft body, a main shaft power input end at the left end, a main shaft power output end at the right end, and a main shaft bolt groove on the end face of the main shaft power output end. The inner rings of the two main shaft bearings are fixed at both ends of the main shaft body. The main shaft, carrying the two main shaft bearings, passes through the main shaft through hole of the stirring support plate and extends into and through the main shaft support cylinder. The right end of the main shaft power output end and the main shaft bolt groove on its end face are exposed for connecting the rotating drum assembly to output rotational power. The outer rings of the two main shaft bearings are supported inside the main shaft support cylinder. The main shaft power input end remains outside the main shaft through hole of the stirring support plate for connecting the stirring transmission system to input rotational power.
[0014] Furthermore, the rotary drum assembly includes a rotary drum, a rotary bolt, and multiple end-sealing plate flexible connection assemblies. The rotary drum has a rotary bearing seat hole in the center of its left end face, two rotary satellite bearing seat holes on each side of the left end face and the corresponding two on each side of the right end face, multiple sliding sleeve fixing holes around the right end face, multiple sliding sleeve mounting through holes on both sides of the left end face, and a rotary bolt groove in the center of the right end face that has the same width and depth as the main shaft bolt groove and can be aligned when the rotary drum assembly is assembled to the outside of the main shaft support assembly. The rotary bolt is fixed in the main shaft bolt groove, and... Located in the rotating drum groove aligned with the main shaft groove, it is used to output the rotational power of the main shaft to the rotating drum assembly; multiple end-sealing plate flexible connection assemblies pass through multiple sliding sleeve mounting holes and are fixed in multiple sliding sleeve fixing holes to fix the end-sealing plate; multiple end-sealing plate flexible connection assemblies apply sensitive elastic force to the end-sealing plate so that the end-sealing plate, along with the end-sealing plate sealing strip fixed in the end-sealing plate sealing strip groove on the right side of the end-sealing plate, forms a tight dynamic seal with the left end face of the end bushing fixed on the stirring shroud.
[0015] Furthermore, the end-sealing plate flexible connection assembly includes a sliding sleeve, a sliding rod, a loose sleeve, and a compression spring. The sliding sleeve passes through the sliding sleeve mounting hole of the rotary drum and is fixed inside the sliding sleeve fixing hole of the rotary drum. The sliding rod passes through the sliding sleeve mounting hole of the rotary drum and is inserted into the sliding sleeve. The end of the sliding rod protrudes from the sliding sleeve and is exposed outside the right side of the rotary drum. The loose sleeve on the left and the compression spring on the right both pass through the end of the sliding rod exposed outside the right side of the rotary drum. The end faces of the ends of the multiple sliding rods are used to fix the end-sealing plate. The multiple compression springs are kept in a compressed state and can be further compressed to apply a sensitive elastic force to the end-sealing plate.
[0016] Furthermore, the satellite stirring assembly includes a satellite shaft, a satellite gear, two satellite shaft bearings, a satellite shaft end sleeve, and the stirring paddle. The outer rings of the two satellite shaft bearings are respectively fitted into the two satellite bearing seat holes on both sides of the rotating drum. The satellite shaft passes partially through the satellite shaft hole of the end sealing plate from right to left. The middle part of the satellite shaft is fitted into the inner rings of the two satellite shaft bearings. The satellite gear is fixed to the left end of the satellite shaft for meshing with the fixed gear. The satellite shaft end sleeve is fitted outside the right side of the middle part of the satellite shaft and fixed to the right side of the end sealing plate, which is pressed by multiple end sealing plate flexible connection components, to dynamically seal the satellite shaft hole of the end sealing plate. The stirring paddle is fixed outside the left end of the satellite shaft. The satellite gear can be rotated by the fixed gear to make the satellite shaft and the stirring paddle rotate and stir the powder.
[0017] Furthermore, the impeller includes an impeller head, two impeller shoulders, two impeller arms, and an impeller foot. The impeller head is fixed to the left end of the satellite shaft. The two impeller shoulders are symmetrically distributed on both sides of the impeller head. The two impeller arms are respectively connected to the two impeller shoulders. The impeller foot is connected between the two impeller arms. When the satellite shaft, together with the impeller, rotates around the center line of the satellite shaft like a satellite, the generatrix of the top surface of the impeller shoulder rotates to form the top surface of the impeller cylinder and is close to the outer end face of the end bushing. The generatrixes of the oppositely twisted sides of the two impeller arms rotate to form the side surface of the impeller cylinder. The generatrix of the bottom surface of the impeller foot rotates to form the bottom surface of the impeller cylinder. The top surface, side surface, and bottom surface of the impeller cylinder combine to form the stirring area of the impeller cylinder.
[0018] Furthermore, when the stirring drive unit drives the two stirring paddles of the stirring mechanism to revolve together like planets through the stirring transmission system, the two cylindrical parts of the two stirring paddles that rotate simultaneously overlap and revolve together, forming a seamless satellite stirring cylinder stirring area, which can disperse and stir the powder in the satellite stirring cylinder stirring area evenly.
