Description

Technical Field

[0001] This utility model relates to the field of copper powder processing technology, and in particular to a grinding and processing equipment for ultrafine copper powder. Background Technology

[0002] Copper powder is a metal powder made from pure copper and pulverized into fine particles, typically in the micrometer or nanometer range. As an important metal powder material, copper powder plays a vital role in many fields.

[0003] In the process of grinding copper powder, simply grinding the copper powder may not guarantee the quality of the copper powder. Without sieving, it is difficult to guarantee the quality of the produced ultrafine copper powder. Therefore, it is necessary to sieve the ground copper powder to ensure its quality.

[0004] However, existing copper powder grinding and processing equipment has the following shortcomings:

[0005] (1) Traditional copper powder grinding equipment cannot screen the ground copper powder. If the ground copper powder is not screened, it may contain larger particles that are not completely ground, abrasive residues or other impurities, which reduces the purity of the copper powder, affects its quality and performance, and the unscreened copper powder may not meet these specific requirements, resulting in limited applications.

[0006] (2) In the process of grinding copper powder, traditional equipment may directly feed the powder through the feed port after grinding. The grinding equipment does not have a screen plate installed inside, which causes the copper powder to be fed directly from the feed port after grinding, resulting in a large number of particles of different sizes, affecting the uniformity of the copper powder. Moreover, the grinding equipment is mostly a whole, making it difficult to clean and maintain the inside. Utility Model Content

[0007] The purpose of this invention is to solve the problem that existing equipment, when in use, uses a sieving mechanism to transport the ground copper powder into the sieve frame, where a vibrating motor vibrates and discharges the powder. To prevent clogging of the sieve, a first motor drives a rotating brush to clean the holes on the outside of the sieve. The finer copper powder passes through the sieve and is conveyed into the feed box. The sieved fine copper powder is then output through the discharge port on the outside of the feed box and transported to the inside of the collection frame. This invention provides a grinding and processing equipment for ultrafine copper powder.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: a grinding and processing equipment for ultrafine copper powder, including a powder screening mechanism, wherein a grinding mechanism is fixedly connected to the bottom of the powder screening mechanism;

[0009] The powder screening mechanism includes a screen frame, a support frame fixedly connected to the top of the screen frame, a first bearing provided on the inner wall of the support frame, a rotating brush rotatably connected to the inner wall of the first bearing, a first motor fixedly connected to the top of the rotating brush, a cover plate movably mounted on the top of the screen frame, a screen mesh fixedly connected to the inner wall of the screen frame, a set of nuts threadedly connected to the outer wall of the screen frame, a material box movably mounted on the bottom of the screen frame, a discharge port fixedly connected to one side of the outer wall of the material box, a set of spring dampers fixedly connected to the bottom of the material box, a connecting frame fixedly connected to the bottom of the set of spring dampers, a vibration motor fixedly connected to the bottom of the material box, and a collection frame provided on one side of the outer wall of the connecting frame.

[0011] Preferably, a material cylinder is fixedly connected to the bottom of the hopper, a screw conveyor is provided on the inner wall of the material cylinder, and a shell is fixedly connected to the outer wall of the material cylinder.

[0012] Preferably, a second bearing is provided on the inner surface of the outer shell, and a grinding roller is rotatably connected to the inner surface of the second bearing.

[0013] Preferably, a second motor is fixedly connected to one side of the outer wall of the grinding roller, a mesh plate is provided on the inner surface of the outer shell, and a set of bolts is movably inserted into the inner surface of the outer shell.

[0015] Preferably, the top of the base plate is fixedly connected to the bottom of the connecting frame, and the top of the base plate is movably connected to the bottom of the collection frame.

[0016] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0017] 1. In this utility model, by setting a sieving mechanism, the ground copper powder is conveyed to the inside of the sieve frame and vibrated by a vibrating motor. To prevent the sieve from clogging, a first motor drives a rotating brush to clean the holes on the outside of the sieve. The finer copper powder is conveyed into the material box through the sieve, and the sieved fine copper powder is output through the discharge port on the outside of the material box and conveyed to the inside of the collection frame. By setting a sieving mechanism, the mechanism can effectively remove impurities from the copper powder, improve the purity and quality of the copper powder, and ensure that the ground copper powder meets the required particle size through sieving. It is also detachable for cleaning.

[0018] 2. In this utility model, by setting up a grinding mechanism, the first moving plate and the second moving plate are simultaneously driven by the second electric push rod to close and open the feed inlet of the mixing chamber. In order to improve the stability of the moving plate, a sliding column is set between the two fixed plates. The mechanism saves manpower and improves the feeding efficiency and the sealing of the mixing chamber by automatically closing and opening the feed inlet of the feed mixing chamber.

[0036] Working Principle: First, check if all parts of the equipment are intact. Then, prepare the copper powder material and pour it into the hopper 203. Simultaneously, start the screw conveyor 206 inside the cylinder 205 to rotate. The copper powder material is conveyed through the screw conveyor 206 inside the cylinder 205 to the inside of the outer shell 207. At the same time, the second motor 210 drives the grinding roller 209 inside the outer shell 207 to rotate. The copper powder forms friction between the grinding roller 209 and the inner wall of the outer shell 207. Under the action of friction, the copper powder rubs and impacts the grinding roller 209 and the inner wall of the outer shell 207. Under the action of the high-speed rotating grinding roller 209, the copper powder is gradually ground into fine particles. The ground fine copper powder particles are fed down through the screen plate 211 set in the feed port. Larger particles can be ground again until they are completely discharged from the mesh opening on the outside of the screen plate 211. If a malfunction or blockage occurs, the bolt 212 can be removed, the side plate 213 on the outside of the equipment can be removed, and the inside can be cleaned and inspected. The ground copper powder is conveyed to the inside of the screen frame 101 through the feed port. At the same time, the vibration motor 113 at the bottom of the material box 109 is started to vibrate and screen the copper powder on the top of the screen 107. If the mesh of the screen 107 is blocked, the first motor 105 can be started to rotate the rotating brush 104 to clean the mesh of the top of the screen 107. The screened copper powder is conveyed to the inside of the material box 109, and then conveyed to the inside of the collection frame 114 placed on the top of the base plate 204 through the discharge port 110 on the outside of the material box 109. At the same time, in order to prevent dust, a collection bag can also be installed at the discharge port 110. After screening, since the screen frame 101 and the material box 109 are connected by screws, the screen frame 101 can be removed, the screened impurities inside can be poured out, and then reassembled.

[0037] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
