[0024] In order to facilitate the understanding of the present invention, the present invention is described more comprehensively with reference to the accompanying drawings. The accompanying drawings provide preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. The purpose of providing these embodiments is to make the disclosure of the present invention more thoroughly and comprehensively understood.

[0025] See attached Figure 1 To Attachment Fig. 9 As shown, Figure 1 and attached Figure 7In the embodiment, a shield crushing device for processing raw materials for lithium battery sintering includes a loading sagger 1 loaded with sintering raw materials, a device body 2, a shield cutter head 3 disposed at the top of the device body 2 and placed vertically inverted, a conveying slide 4 and a suction device 6 disposed below the shield cutter head 3 and used for conveying the loading sagger 1, wherein at least one suction hole 33 is provided on the shield cutter head 3 for the suction device 6 to suck materials; the shield cutter head 3 is provided with a driving unit 5 for driving it to reciprocate in the up and down directions. Specifically, after the charging sagger 1 is fed into the device body 2, the charging sagger 1 is fed along the conveying slide 4; then, when the charging sagger 1 is conveyed and positioned directly below the shield cutter head 3, the shield cutter head 3 is driven by the driving unit 5 to be axially fed downward until it contacts the surface of the sintered raw material in the charging sagger 1; at this time, the shield cutter head 3 starts to rotate and progressively mills layer by layer in the charging sagger 1 to shield-crush the sintered raw material in the charging sagger 1, and while the shield cutter head 3 is performing the shield-crushing operation, the suction device 6 starts to suck the material, and sucks the sintered raw material crushed by the shield cutter head 3 away from the suction hole 33 ( Here, the aperture size and number of the suction holes 33 are set according to production requirements and the specifications and models of the suction device 6, and are not limited here); thus, through the screening function of the aperture of the suction holes 33, the sintered raw material fragments with a particle size that meets the production size requirements are sucked into the suction device 6 (the suction device 6 here can be externally connected to a collecting device to extract the stored sintered raw material fragments for subsequent production use), and the sintered raw material particle size screening is realized while collecting the sintered raw material fragments to ensure that the particle size of the sintered raw material fragments meets the production size requirements, effectively avoiding the accumulation of sintered raw material fragments in the charging sagger 1 and affecting the subsequent crushing work of the shield cutter head 3.

[0026] More specifically, when the shield cutter head 3 reaches a preset advancement amount (the preset advancement amount here is set according to the specifications of the loading sagger 1 and the feeding speed of the shield cutter head 3, and when the shield cutter head 3 reaches the preset advancement amount, the shield cutter head 3 is about to contact the inner bottom wall of the loading sagger 1, thereby achieving the best crushing effect), the shield crushing operation is completed, and the shield cutter head 3 is controlled to rise and reset, waiting for the next loading sagger 1 to be transported and positioned directly below the shield cutter head 3 to repeat the shield crushing operation.

[0027] Among them, the shield cutter head 3 in this embodiment includes a shank seat 31 and a cutter disc 32. Specifically, the shank seat 31 can be fixedly connected to the device body 2 by welding, screw connection, etc.; the cutter disc 32 is rotatably connected to the bottom end of the shank seat 31, and at least one Lenaud triangle blade 321 is installed at a certain angle at the bottom end of the cutter disc 32, and in this embodiment, three Lenaud triangle blades 321 are installed at an angle to improve the crushing efficiency. As a result, each blade can break the surface with a point when rotating, greatly improving the crushing effect of the sintered raw materials; at the same time, each blade can be closer to the inner wall of the loading sagger 1 when rotating, and the sintered raw materials adhered to the inner wall of the sagger can be unloaded, so as to achieve thorough and uniform crushing. More specifically, the suction device 6 in this embodiment includes a suction pipe, which is arranged in parallel with the tool rod seat 31, and the upper end of the suction pipe can be externally connected to the collecting device and serve as a discharge port, and the lower end can be close to the suction hole 33 to serve as a suction port; wherein, in order to improve the suction effect, three suction holes 33 are opened on the shield cutter head 3 to make the suction coverage wider; and the shape of each suction hole 33 matches the shape of the suction port of the suction pipe (that is, the shape of the suction hole 33 matches the shape of the suction port of the suction pipe, and the size of the suction hole 33 is slightly larger than or equal to the size of the suction port) so that when the suction port and the suction hole 33 are close to suction, the port can completely cover the suction, thereby improving the suction accuracy and suction efficiency; and the suction port of the suction pipe in this embodiment adopts a rectangular structure, which can achieve a better suction effect.

[0028] Furthermore, in order to realize the accurate conveying and positioning of the loading sagger 1, the loading sagger 1 is accurately stopped directly below the shield cutter head 3. In this embodiment, the conveying slide 4 is arranged along the length of the device body 2 or in the width direction according to the position of the inlet and outlet of the loading sagger 1 on the device body 2; and the device body 2 is provided with a stopper 9 on at least one side of the conveying direction of the conveying slide 4 and adjacent to the shield cutter head 3, and the stopper 9 can be partially extended into the conveying slide 4 to block the conveying slide 4. When the loading sagger 1 is conveyed to the stopper 9, it touches the stopper 9 and is stopped, and then is limited and stops moving; wherein, the stopper 9 in this embodiment uses a blocking cylinder, and the working principle of the blocking cylinder belongs to conventional technical means, which will not be elaborated here.

[0029] Secondly, the device body 2 is provided with a clamp 8 on both sides of the conveying direction of the conveying slide 4, and the two clamps 8 are respectively located at the opposite sides directly below the shield cutter head 3; when the loading sagger 1 is conveyed thereto, the two clamps 8 respectively clamp and press on the opposite sides of the loading sagger 1 to clamp and fix the loading sagger 1 and at the same time drive the loading sagger 1 to move along the front and rear direction to fine-tune the position of the loading sagger 1, so that the loading sagger 1 is opposite to the shield cutter head 3 in the vertical direction (that is, the loading sagger 1 is aligned with the shield cutter head 3 in the vertical direction); wherein, the clamp 8 in this embodiment uses a centering cylinder, and the working principle of the centering cylinder belongs to conventional technical means, which will not be elaborated here.

[0030] In addition, in order to avoid a large amount of dust generated during the crushing process of the sintered raw materials, which may cause dust pollution, in this embodiment, the device body 2 is provided with an accordion cover 7 along the edges around the outer sides of the shield cutter head 3. During crushing, the accordion cover 7 surrounds the shield cutter head 3 and the charging sagger 1, so that the dust generated during the crushing process of the sintered raw materials is blocked by the inner wall of the accordion cover 7 and cannot penetrate, effectively preventing dust from splashing and polluting the environment, and endangering the surrounding environment and the health of the operators.

[0031] For ease of understanding, the shield crushing device for processing raw materials for sintering of lithium batteries is further described below in conjunction with a specific working method.

[0032] The shield crushing device for processing lithium battery sintering raw materials in this embodiment includes the following steps:

[0033] Step S1. A plurality of loading saggers 1 loaded with sintering raw materials to be crushed are sequentially waiting to be transported into the shield crushing device.

[0034] Step S2. A single loading sagger 1 enters from the entrance of the shield crushing device, is sent to the stopper 9 through the conveying slide 4 and is stopped and limited, and is then clamped and fixed in the center by the clamp 8; then, the shield clamp descends to contact the surface of the sintered raw material in the loading sagger 1 and starts to rotate for crushing. At this time, the suction device 6 is synchronously opened, and the sintered raw material crushed materials with a particle size that meets the production size requirements will be sucked away and collected through the suction hole 33 by the suction device 6.

[0035] Step S3. When the shield cutter head 3 reaches the preset progressive amount, the shield crushing operation is completed, and the shield cutter head 3 is controlled to rise and reset; then, the two clamps 8 and the stopper 9 are controlled to avoid and exit the conveying slide 4, and the empty loading sagger 1 is moved and sent out along the conveying slide 4, and the above steps S1 to S3 are repeated to complete the crushing operation of multiple loading saggers 1 loaded with sintering raw materials to be crushed. In this way, the crushing operation of large quantities of sintering raw materials is realized.
