[0027] This utility model provides a ball milling device for lithium battery cathode materials, including a fixed base plate 101, a ball mill body 102, and a collection assembly. The collection assembly includes a fixed plate 103, a collection box 104, casters 105, a supporting base plate 106, a moving handle 107, a fixing component, a rubber sleeve 108, a reinforcing frame 109, and an observation window 110. The fixing component includes a connecting base plate 111, a fixing frame 112, an abutment plate 113, a mounting component, a moving component, and a rubber pad 114. The mounting component includes a mounting frame 115 and mounting bolts 116. The moving component includes a limiting slide 117, fixing bolts 118, and an anti-detachment block 119. The fixing frame 112 has a sliding through hole 120. This solution solves the problem that existing equipment often discharges milled raw materials directly onto the ground, making it difficult for operators to collect and transport them. It is understood that this solution can be used in situations where convenient centralized collection and transportation of discharged raw materials is required.

[0028] In this embodiment, the ball mill body 102 is mounted on the fixed base plate 101. The ball mill body 102 can process lithium battery cathode materials. The structure of the ball mill body 102 is described in detail in the prior art CN221310891U, and will not be repeated here.

The supporting base plate 106 is fixedly connected to the fixed base plate 101 and is located on the side of the fixed base plate 101 near the universal wheel 105. The moving handle 107 is fixedly connected to the collection box 104 and is located on one side of the collection box 104. The fixing member is mounted on the ball mill body 102 and connected to the fixed plate 103. There are two fixing plates 103, which are connected to the lower part of the ball mill body 102 by the fixing member. The collection box 104 is welded to the two fixing plates 103. The collection box 104 can collect the material processed by the ball mill body 102. There are four casters 105, which are arranged below the collection box 104. The rolling of the casters 105 can facilitate the transport and movement of the collection box 104 on the plane. The supporting base plate 106 is welded to the fixing base plate 101. The supporting base plate 106 can support the collection box 104 and the casters below the ball mill body 102. The ball mill body 104 is supported by wheels 105. A movable handle 107 is welded to the collection box 104, allowing the operator to easily move the collection box 104. A fixing component is mounted on the ball mill body 102 and connected to the fixing plate 103. This fixing component secures the fixing plate 103 to the underside of the ball mill body 102. When materials processed by the ball mill body 102 need to be collected, the operator pushes the collection box 104 onto the supporting base plate 106 below the ball mill body 102, causing the fixing plate 103 to move to a corresponding installation position. The fixing component then secures the fixing plate to the base plate. The 103 and its collection box 104 are connected and fixed below the ball mill body 102. The collection box 104 can collect the material processed by the ball mill body 102. After collection, it contacts the fixing component to fix the fixing plate 103, so that the operator can push the universal wheel 105 below the collection box 104 to move the collection box 104 by pushing it with the moving handle 107. Thus, the rolling of the collection box 104 and the universal wheel 105 can prevent the raw material after ball milling from being discharged directly onto the ground. This allows the operator to push the collection box 104 after collection to collect and transport the raw material after ball milling.

The two abutment plates 113 are connected to the corresponding two fixed frames 112 via the moving component. The moving component can drive the abutment plates 113 to move towards the connecting base plate 111, thereby enabling the connecting base plate 111 to abut and clamp the fixed plate 103 between the abutment plates 113 and the connecting base plate 111 through the movement of the abutment plates 113. The mounting component is disposed on the ball mill body 102 and connected to the connecting base plate 111 and the fixed frame 112. The mounting component connects and fixes the connecting base plate 111 and the fixing frame 112 to the ball mill body 102. The moving component is disposed on the fixing frame 112 and connected to the abutment plate 113. The moving component can drive the abutment plate 113 to move. There are two rubber pads 114, which are bonded to the corresponding two abutment plates 113.

[0032] Additionally, the limiting slide 117 is slidably connected to the fixed frame 112 and fixedly connected to the abutment plate 113, and is located on the side of the fixed frame 112 closer to the abutment plate 113; the fixing bolt 118 is disposed on the fixed frame 112 and abuts against the abutment plate 113; the anti-detachment block 119 is fixedly connected to the limiting slide 117 and is located on the side of the limiting slide 117 away from the abutment plate 113; the sliding through hole 120 is located at...

The fixing frames 112 can connect, support, and directionally limit the sliding of the limiting slides 117. Two abutment plates 113 are welded to the four corresponding limiting slides 117, thereby allowing the limiting slides 117 to move. The device can connect, support, and directionally limit the movement of the abutment plate 113. There are two fixing bolts 118, which are set on the corresponding two fixing brackets 112. The fixing brackets 112 have threaded holes that cooperate with them. By turning the fixing bolts 118, the fixing bolts 118 can move and abut against the top of the abutment plate 113, thereby pushing the abutment plate 113 to move downward to cooperate with the connecting base plate 111 to abut against and clamp the fixing plate 103. There are four anti-detachment blocks 119, which are welded to the corresponding four limiting slides 117. The anti-detachment blocks 119 can prevent the limiting slides 117 from moving excessively and detaching from the fixing brackets 112. The fixing brackets 112 have sliding through holes 120, which can achieve the purpose of directional limiting movement of the limiting slides 117 on the fixing brackets 112.

[0033] Finally, the rubber sleeve 108 is fixedly connected to the movable handle 107 and located on one side of the movable handle 107; the reinforcing frame 109 is fixedly connected to the movable handle 107 and the collection box 104 respectively, and located on the side of the movable handle 107 near the collection box 104; the observation window 110 is fixedly connected to the collection box 104 and located on one side of the collection box 104.

The fixing plate 103 and the collection box 104 are connected and fixed below the ball mill body 102 by the fixing component. The collection box 104 can collect the material after processing by the ball mill body 102. After collection, the fixing plate 103 is fixed by contact with the fixing component, so that the operator can push the universal wheel 105 below the collection box 104 to move the collection box 104 by pushing it with the moving handle 107. Thus, the rolling of the collection box 104 and the universal wheel 105 can prevent the raw material after ball milling from being discharged directly onto the ground, so that the operator can push the collection box 104 after collection to collect and transport the raw material after ball milling.
