Please refer to Figures 1 to 4As shown in the figure, a preferred embodiment is shown, which is an automatic unpacking and feeding machine for lithium battery slurry mixing, including a base 1, a feeding assembly 2, a cutting mechanism 3, a slurry mixing barrel 4, a material guiding mechanism 5 and a driving member 6. The upper end of the base 1 is provided with a feeding assembly 2. One end of the feeding assembly 2 is provided with a driving member 6. The output end of the driving member 6 is provided with a cutting mechanism 3. The slurry mixing barrel 4 is arranged inside the base 1. The slurry mixing barrel 4 faces the feeding assembly 2. The upper end of the slurry mixing barrel 4 is provided with a material guiding mechanism 5. In this embodiment, refer to Figure 1 As shown in the figure, one end of the feeding assembly 2 is connected to one side of the upper end of the base 1. The base 1 is provided with an open upper end. The lower end of the slurry mixing barrel 4 is arranged on the lower inner wall of the base 1. The material guiding mechanism 5 is located at the upper end of the slurry mixing barrel 4 and is detachably connected to the slurry mixing barrel 4. The material guiding mechanism 5 is used to guide the slurry mixing material into the slurry mixing barrel 4. The empty material bag 8 can enter the vicinity of the slurry mixing barrel 4, that is, the inside of the base 1 under the action of the material guiding mechanism 5. Among them, after the material bag 8 enters the feeding assembly 2, the driving member 6 drives the cutting mechanism 3 to rotate to cut the bottom of the material bag 8, so that the material bag 8 is automatically cut open, facilitating the falling of the slurry mixing material inside the material bag 8, eliminating manual operation and improving work efficiency. The empty material bag 8 will be concentrated in the base 1 for easy manual collection.

[0027] Further, as a preferred implementation manner, the feeding assembly 2 includes a first bracket 201 and a feeding cylinder 202. One end of the first bracket 201 is connected to the base 1, and the other end of the first bracket 201 is connected to the feeding cylinder 202. The feeding cylinder 202 is provided with upper and lower openings. Among them, one end of the first bracket 201 is connected to one side of the upper end of the base 1 by bolts or welding. The feeding cylinder 202 is connected to the first bracket 201 by welding or bolts. The material bag 8 enters the feeding cylinder 202. At this time, the outer wall of the material bag 8 abuts against the inner wall of the feeding cylinder 202, and the bottom of the material bag 8 will abut against the upper end of the material guiding mechanism 5, facilitating the direct falling of the slurry mixing material on the material guiding mechanism 5 after the material bag 8 is cut.

[0028] Further, as a preferred implementation manner, it further includes a second bracket 7. One end of the second bracket 7 is connected to the feeding assembly 2, and the other end of the second bracket 7 is connected to the driving member 6. Among them, the driving member 6 is a motor. One end of the second bracket 7 is fixedly welded to the side wall of the feeding cylinder 202, and the driving member 6 is installed on the upper side of the other end of the second bracket 7. The output end of the driving member 6 penetrates the second bracket 7 and extends to the lower end of the second bracket 7.

[0029] Further, as a preferred embodiment, the cutting mechanism 3 includes a rotating arm 301 and a saw blade 302. One end of the rotating arm 301 is connected to the output end of the driving member 6, and the other end of the rotating arm 301 is provided with a saw blade 302. The saw blade 302 is disposed opposite to the position between the feeding assembly 2 and the guiding mechanism 5. The outer edge of the saw blade 302 is a sharp cutting edge, capable of cutting open the bracket of the material package 8. The output end of the driving member 6 is connected to the rotating arm 301, which can drive the rotating arm 301 to rotate, and the rotating arm 301 can drive the saw blade 302 to rotate, facilitating the cutting of the material package 8. Moreover, the radius of the saw blade 302 is greater than the thickness of the material package 8.

[0030] Further, as a preferred embodiment, the guiding mechanism 5 includes a retaining net 501. The retaining net 501 is installed at the upper end of the pulp mixing barrel 4 and has a frustum-shaped structure with a wider upper part and a narrower lower part. Since the pulp mixing material is in powder form, it is convenient to directly pass through the retaining net 501 and enter the pulp mixing barrel 4. The outer wall of the retaining net 501 is inclined, facilitating the material package 8 to slide along the outer wall of the retaining net 501 and fall into the base 1.

[0031] Further, as a preferred embodiment, it further includes a support block 502. The upper end of the retaining net 501 is provided with a support block 502, and a through hole 503 is formed in the support block 502. Through the setting of the through hole 503, it is convenient to inject other liquid materials into the pulp mixing barrel 4, facilitating subsequent pulp mixing. Among them, when the material package 8 is placed in the feeding cylinder 202, the lower end of the material package 8 can abut against the support block 502.

[0032] Further, as a preferred embodiment, it further includes an outer shell 203, a light emitter 204, and a light receiver 205. The two outer shells 203 are respectively disposed on both sides of the feeding cylinder 202. The light emitter 204 and the light receiver 205 are respectively fixedly connected inside the two outer shells 203, and the light receiver 205 is electrically connected to the driving member 6. The outer shell 203 is used to protect the light emitter 204 and the light receiver 205. The light emitted by the light emitter 204 can be received by the light receiver 205, used to determine whether there is a material package 8 inside the feeding cylinder 202. And the light receiver 205 is electrically connected to the driving member 6. When the light emitted by the light emitter 204 cannot be received, it indicates that there is a material package 8 inside the feeding cylinder 202 at this time. At this time, the light receiver 205 can send a signal to the driving member 6, causing the driving member 6 to start working.

[0033] As a preferred embodiment, it further includes a PLC controller. The PLC controller is disposed on the outer wall of the base 1 and is used to be electrically connected to the driving member 6 and the light receiver 205. The light receiver 205 can send a signal to the PLC controller, and then the PLC controller controls the driving member 6 to start or pause.

[0034] Further, as a preferred embodiment, it further includes a glass sheet 206. Light-transmitting holes 207 are formed on both sides of the feed cylinder 202, and a glass sheet 206 is respectively arranged in each light-transmitting hole 207. The arranged glass sheet 206 is used to seal the light-transmitting holes 207 and can also prevent the outer wall of the material packet 8 from directly contacting the light receiver 205 or the light emitter 204, thereby protecting the light receiver 205 and the light emitter 204.

[0035] Further, as a preferred embodiment, there is a gap between the glass sheet 206 and the inner wall of the feed cylinder 202, which can prevent the dust on the outer wall of the material packet 8 from directly contacting the glass sheet 206 and causing the phenomenon that the glass sheet 206 is not clear in light transmission. Among them, the glass sheet 206 can be wiped regularly.

[0036] During use, the material packet 8 is placed into the feed cylinder 202 so that the bottom of the material packet 8 abuts against the support block 502. At this time, the light receiver 205 cannot receive the light emitted by the light emitter 204. Then the light receiver 205 sends a signal to the driving member 6, and the driving member 6 starts to drive the rotating arm 301 to rotate, and the rotating arm 301 will drive the saw blade 302 to rotate, so that the saw blade 302 cuts open the bottom of the material packet 8. Then the mixing slurry material in the material packet 8 falls onto the retaining net 501 and enters the mixing slurry barrel 4 through the holes in the retaining net 501. Then the empty material packet 8 or the material packet 8 with some remaining mixing slurry material will fall onto the side wall of the retaining net 501 and can slide down along the retaining net 501 to the inside of the base 1 and accumulate inside the base 1, which is convenient for manual collection later. When manually collecting the empty material packet 8, the mixing slurry material scattered inside the base 1 can be collected at the same time. When the material packet 8 detaches from the feed cylinder 202, at this time the light receiver 205 can receive the light emitted by the light emitter 204, and then the light receiver 205 sends a signal to the driving member 6, and the driving member 6 stops working.

[0037] The above are only the preferred embodiments of the present invention, and thus do not limit the implementation manners and protection scope of the present invention. For those skilled in the art, it should be realized that all the equivalent replacements and obvious changes made by using the description and illustrations of the present invention should be included in the protection scope of the present invention.
