[0002] In modern industrial production, metal powder raw materials are widely used, covering many fields such as electronics, aerospace, new energy, and building materials. In the manufacture of new energy batteries, metal powders of specific specifications are used as electrode materials, which play a key role in the battery's charge and discharge performance and lifespan. However, many conventional crushers only have a single crushing function, making it difficult to achieve multi-stage crushing of metal raw materials, resulting in uneven particle size of the final product and difficulty meeting the needs of high-precision industrial production. In particular, some simple jaw crushers rely solely on the relative movement of two jaw plates to squeeze and crush the material, and are unable to perform fine processing of the material. During the crushing process, some crushing equipment has poor grinding effect on the metal, resulting in irregular particle shape of the powder, which affects the formability and fluidity of the metal powder in subsequent processing. Summary of the Invention

[0028] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0029] The following describes a metal powder raw material crushing device with a multi-stage gear roller linkage provided by some embodiments of the present invention in conjunction with the accompanying drawings.

[0030] Example 1:

[0031] In the powder metallurgy industry, if the metal powder has an irregular shape, the density of the pressed green body will be uneven, which will affect the product quality. In order to solve the above problems, combined with Figure 1 、 Figure 2 、 Figure 4 and Figure 5 As shown, the multi-stage gear roller linkage metal powder raw material crushing device provided by the present invention includes a housing 100, and a grinding mechanism 200 and a crushing mechanism 300 for multiple metal crushing are disposed within the housing 100, so that the metal raw material can be crushed multiple times in the same closed space, thereby reducing dust emission, improving the working environment, and increasing production efficiency while reducing equipment installation and maintenance costs.

[0032] Conventional equipment often lacks an efficient screening and reprocessing mechanism. For metal particles that do not meet the particle size standards, it is impossible to perform secondary crushing in a timely and effective manner, which reduces production efficiency and raw material utilization. In order to solve the above problems, the grinding mechanism 200 includes a filter plate 1 201 fixed to the housing 100, and filter plates 202 are hinged on both sides of the filter plate 1 201. The filter plate 202 is installed at an angle, and multiple springs 206 are fixed between the filter plate 202 and the inner wall of the housing 100. A grinding roller 204 for crushing metal is movably installed in the housing 100. The housing 100 0 is fixedly attached to a triangular plate 203, located above filter plate 1 201 and filter plate 2 202. After a single grinding operation, metal powder is guided by triangular plate 203 onto filter plate 2 202. The powder then moves diagonally downward. Powder that meets the size standard is discharged through the filter holes, while powder that does not meet the size standard moves to filter plate 1 201. Grinding roller 204 then moves back and forth on filter plate 1 201, re-grinding the non-standard powder. Filter plate 1 201 and the hinged filter plate 2 202 cooperate with spring 206 to form an elastic screening system. When grinding roller 204 performs a secondary grinding of non-standard powder, the elastic vibration of the filter plates facilitates powder flow and screening, improving screening efficiency and accuracy. The guiding effect of triangular plate 203 ensures more even powder distribution, avoids localized accumulation, and further enhances the grinding effect.

[0033] Specifically, a screw 208 is rotatably installed in the housing 100, and a slide bar 212 is also fixedly connected. A connecting frame 213 is threadedly connected to the screw 208. The connecting frame 213 is slidably connected to the slide bar 212. A transmission shaft 214 is rotatably installed on the connecting frame 213. The end of the transmission shaft 214 is fixedly connected to a spur gear 215. A rack 211 meshing with the spur gear 215 is fixedly connected in the housing 100. The grinding roller 204 is sleeved on the transmission shaft 214. The grinding roller 204 fits with the filter plate 201. The screw 208 rotates to drive the connecting frame 213 to move. The connecting frame 213 drives the grinding roller 204 on the transmission shaft 214 to move, and at the same time, the spur gear 215 on the transmission shaft 214 engages with the rack 211 to drive the transmission shaft 214 thereon to rotate, and the grinding roller 204 rotates along with the transmission shaft 214, so that the grinding roller 204 also rotates during the movement, thereby improving the quality of powder grinding. Subsequently, the ground powder is discharged through the filter holes on the filter plate 201, which increases the contact area and friction times between the grinding roller 204 and the powder, significantly improving the grinding quality of the powder, and making the particle size of the final product more fine and uniform.

[0034] Furthermore, a feed port 102 is provided above the housing 100 , a discharge port is provided below the housing 100 , and a material frame 103 is placed below the discharge port. The discharged powder falls into the material frame 103 , and the crushed powder is collected centrally.

[0035] A chassis 101 for protecting the power assembly is installed on the side of the housing 100. Motor 1 207 and motor 2 307 are both located in the chassis 101, which can protect the power assembly.

[0036] According to the embodiment, chassis 101 encloses and protects power components such as motor 1 207 and motor 2 307, effectively preventing metal powder from corroding and damaging the motors, extending the motor's service life and reducing equipment failure rates and maintenance costs. Furthermore, chassis 101 reduces noise generated by the motors during operation, improving the working environment.

[0037] Example 2:

[0038] Combine Figure 4As shown, on the basis of embodiment 1, connecting shafts 210 are rotatably installed on both sides of the shell 100, and a cam 205 is mounted on the connecting shaft 210. The cam 205 is located below the adjacent filter plate 202 and is used to drive the filter plate 202 to vibrate. A belt assembly 209 is provided between the connecting shaft 210 and the screw 208. A motor 207 for driving the screw 208 to rotate is fixedly installed on the shell 100. The motor 207 starts to drive the screw 208 to rotate, and the screw 208 drives the connecting shaft 210 to rotate through the belt assembly. The connecting shaft 210 drives the cam 205 to rotate. The cam 205 rotates and contacts the filter plate 202 to cause it to vibrate, thereby increasing the speed at which the powder passes through the filter holes. The movement of the grinding roller 204 and the vibration of the filter plate 202 can be achieved by using a single motor 207, thereby reducing the manufacturing cost of the equipment.

[0039] According to the embodiment, the belt assembly 209 includes a pulley mounted on the screw 208 and the connecting shaft 210, and the pulleys are connected via a belt transmission.

[0040] Example 3:

[0041] Combine Figure 2 and Figure 3 As shown, based on the first embodiment, the pulverizing mechanism 300 includes two bearing shafts 1 303 rotatably mounted within the housing 100. Each bearing shaft 1 303 is fitted with a crushing roller 301. Both bearing shafts 1 303 are fitted with meshing spur gears 2 304. A motor 2 307 is fixed to the housing 100 to drive one of the bearing shafts 1 303. When motor 2 307 is activated, bearing shaft 1 303 rotates. Bearing shaft 1 303, via spur gear 2 304, drives the other bearing shaft 1 303 in reverse rotation, causing the crushing rollers 301 on the two bearing shafts 1 303 to rotate in opposite directions, pulverizing the metal. Upon entering the pulverization zone, the metal material is subjected to two opposing squeezing and shearing forces, effectively crushing larger metal particles. This relative rotation also prevents the metal material from slipping during the pulverization process, improving crushing efficiency and reducing energy consumption. Furthermore, the meshing transmission of spur gears 2 304 ensures the synchronization of the rotational speeds of the two crushing rollers 301, ensuring a stable and consistent crushing effect.

[0042] Specifically, two bearing shafts 305 are rotatably mounted within the housing 100. Grinding columns 302 are mounted on bearing shafts 305, and meshing spur gears 3 are mounted on bearing shafts 305. A belt assembly 2 306 is provided between bearing shaft 1 303 and bearing shaft 2 305. Belt assembly 1 209 and belt assembly 2 306 have the same structure. Bearing shaft 1 303 drives bearing shaft 2 305 to rotate via belt assembly 2 306. Bearing shaft 2 305 then drives the other bearing shaft 2 305 in reverse direction via spur gear 3, causing the grinding columns 302 on the two bearing shafts 1 303 to rotate in opposite directions, further crushing the metal. This allows motor 2 307 to simultaneously drive the grinding columns 302 while driving the crushing roller 301, resulting in a secondary crushing of the metal. The relative rotation of the grinding columns 302 further refines the metal particles, improving the fineness and uniformity of the product. At the same time, the use of the second belt assembly 306 simplifies the transmission structure, reduces the complexity and manufacturing cost of the equipment, and can also play a role in buffering and overload protection, thereby extending the service life of the equipment.

[0043] A baffle 308 is fixedly connected to the housing 100 , and the baffle 308 is located outside the crushing roller 301 .

[0044] It can be seen from the above embodiment that: the metal raw material enters the shell 100 from the feed port 102, the motor 2 307 is started to drive one of the bearing shafts 1 303 to rotate, and the bearing shaft 1 303 drives the other bearing shaft 1 303 to reverse through the spur gear 2 304, so that the two crushing rollers 301 rotate relative to each other to perform the initial crushing of the metal; at the same time, the bearing shaft 1 303 drives the bearing shaft 2 305 to rotate through the belt assembly 2 306, and the bearing shaft 2 305 drives the other bearing shaft 2 305 to reverse through the spur gear 3, so that the two grinding columns 302 rotate relative to each other to crush the metal again. After the initial crushing, the metal powder is guided to the second filter plate 202 through the triangular plate 203. Powder that meets the size standard is discharged through the filter holes, and powder that does not meet the size standard is moved to the first filter plate 201. The motor 1 207 is started to drive the screw 208 to rotate. The screw 208 drives the connecting frame 213 to move on the slide bar 212. The connecting frame 213 drives the transmission shaft 214 and the grinding roller 204 to move. At the same time, the spur gear 1 215 engages with the rack 211 to rotate the transmission shaft 214, which drives the grinding roller 204 to rotate, and the powder that does not meet the standard on the filter plate 1 201 is ground again. The ground powder is discharged through the filter holes of the first filter plate 201. The rotation of the screw 208 also drives the connecting shaft 210 to rotate through the belt assembly 1 209. The connecting shaft 210 drives the cam 205 to rotate. The cam 205 drives the second filter plate 202 to vibrate, thereby increasing the speed at which the powder passes through the filter holes. Finally, all powder that meets the size falls into the material frame 103 through the discharge port for centralized collection.

[0046] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
