Description

Technical Field

[0001] This utility model relates to the field of vertical grinding machines for producing zinc powder with uniform and stable grinding, and in particular to a vertical grinding machine for producing zinc powder with uniform and stable grinding. Background Technology

[0002] A grinding mill is a machine that grinds large solid raw materials to the required size. Driven by electricity, it uses grinding media to process the raw materials, representing a refined pulverization process. Grinding mills are widely used in many sectors such as mining, metallurgy, building materials, highways, railways, water conservancy, and chemical industries. In the production of zinc powder, the particle size is inconsistent, necessitating further processing with a grinding mill to improve the quality of the zinc powder.

[0003] For example, the utility model disclosed in CN217796620U discloses a vertical grinding mill for producing uniform and stable zinc powder. This mill uses a feed cone plate to allow zinc powder to fall from the top of the feed box. When the feed box rotates to the bottom, the zinc powder entering from the bottom cannot fall through the feed cone plate, preventing zinc powder from scattering during the rotation of the feed box and improving the stability of the device. However, most current vertical grinding mills for producing uniform and stable zinc powder cannot fully grind the material during use, leading to incomplete grinding and failure to achieve the appropriate fineness. This necessitates secondary grinding, which is time-consuming, labor-intensive, and impractical. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, this utility model provides a vertical grinding mill for producing zinc powder with uniform and stable grinding. It solves the problem that existing vertical grinding mills for zinc powder production use a feed cone plate to allow zinc powder to fall from the top of the feed box. When the feed box rotates to the bottom, the zinc powder entering from the bottom cannot fall through the feed cone plate, preventing zinc powder from scattering during the rotation of the feed box and improving the stability of the device. However, most current vertical grinding mills for producing zinc powder with uniform and stable grinding cannot fully grind the material during use, leading to incomplete grinding and failure to achieve the appropriate fineness. This results in the need for secondary grinding, which is time-consuming, labor-intensive, and impractical.

[0005] To solve the above technical problems, this utility model provides the following technical solution: a vertical grinding machine for producing zinc powder with uniform and stable grinding, comprising a machine body, a top cover distributed on the top of the machine body, a cylinder provided at the bottom corner of the top cover, a first motor provided at the top center of the top cover, and a rotating shaft connected to the output end of the first motor, a first grinding roller sleeved on the outer surface of the rotating shaft, and a second grinding roller distributed below the first grinding roller, a first grinding chamber opened on the inner side of the top of the machine body, and the bottom of the first grinding chamber connected to the second grinding chamber, a first protrusion provided on the inner side wall of the top of the machine body, a sieve plate provided on the inner side of the first grinding chamber, a guide seat distributed on the west side of the sieve plate, a fixed seat provided at the bottom of the guide seat, and an auxiliary structure provided on the inner side of the fixed seat, the auxiliary structure including a second motor, a rotating plate, a rotating roller, and a second protrusion, the second motor being fixedly installed on the inner side of the fixed seat, and the output end of the second motor being connected to the rotating plate, a rotating roller being connected to the bottom of one end of the rotating plate, and a second protrusion being provided on the surface of the rotating roller.

[0006] As a preferred embodiment of this utility model, the bottom inner wall of the machine body is provided with a slide rail, and a collection frame is distributed on one side of the slide rail, and a pulley is rotatably connected to the side wall of the collection frame.

[0007] As a preferred embodiment of the present invention, the first grinding roller is symmetrically distributed along the vertical center line of the rotating shaft, and the first grinding roller and the second grinding roller are distributed in parallel.

[0008] As a preferred embodiment of the present invention, the first protrusion is equidistantly distributed along the center point of the body, and the first protrusion and the body form an integrated structure.

[0009] As a preferred embodiment of this utility model, the second protrusion is equidistantly distributed along the center point of the rotating roller, and the rotating roller is symmetrically distributed along the vertical center line of the rotating plate.

[0010] Compared with the prior art, the beneficial effects that this utility model can achieve are:

[0011] 1. By using the first motor, rotating shaft, grinding roller and first protrusion, the subsequent grinding process of the material can be easily and fully realized, and the material to be ground can be ground to a suitable fineness for convenient use. When the first motor works, the rotating shaft will rotate accordingly, and then the rotation of the rotating shaft realizes the synchronous movement of the grinding roller. Combined with the setting of multiple first protrusions, the material can be fully ground, and the whole structure has a higher grinding effect.

[0012] 2. By using the second motor, rotating plate, and rotating roller, the material after the initial grinding process can be further ground to achieve a thorough grinding process. When the second motor is working, the rotating plate will rotate accordingly, and the rotating plate will drive the rotating roller connected to its bottom to move synchronously. Then, combined with the multiple second protrusions set on the surface of the rotating roller, the grinding process of the material can be further achieved. Attached Figure Description

A first grinding chamber 8 is opened on the inner side of the top of the machine body 1, and the bottom of the first grinding chamber 8 is connected to a second grinding chamber 9. A first protrusion 10 is arranged on the inner side wall of the top of the machine body 1. A sieve plate 11 is arranged on the inner side of the first grinding chamber 8, and a guide seat 12 is distributed on the west side of the sieve plate 11. A fixed seat 13 is arranged at the bottom of the guide seat 12, and an auxiliary structure is arranged on the inner side of the fixed seat 13. A slide rail 18 is arranged on the inner side wall of the bottom of the machine body 1, and a collection frame 19 is distributed on one side of the slide rail 18. A pulley 20 is rotatably connected to the side wall of the collection frame 19.

[0021] In use, the zinc powder to be ground is placed on the inner side of the top of the machine body 1. Then, the zinc powder is fully ground by the grinding roller and rotating roller 16. The ground material will fall into the inner side of the collection box 19, which is convenient to slide along the slide rail 18 by the pulley 20, so that the ground zinc powder can be taken out.

[0022] As a further implementation of this embodiment, such as Figure 1 , Figure 2 , Figure 3 and Figure 4The machine body 1 shown has a top cover 2 on its upper part, and a cylinder 3 is installed at the bottom corner of the top cover 2. A first motor 4 is installed at the top center of the top cover 2, and the output end of the first motor 4 is connected to a rotating shaft 5. A first grinding roller 6 is fitted on the outer surface of the rotating shaft 5, and a second grinding roller 7 is distributed below the first grinding roller 6. The first grinding roller 6 is symmetrically distributed along the vertical center line of the rotating shaft 5, and the first grinding roller 6 and the second grinding roller 7 are parallel to each other. A first grinding cavity 8 is opened on the inner side of the top of the machine body 1, and the bottom of the first grinding cavity 8 is connected to the second grinding cavity 9. A first protrusion 10 is provided on the inner side wall of the top of the machine body 1. The first protrusion 10 is equidistantly distributed along the center point of the machine body 1, and the first protrusion 10 is connected to the machine body 1. The body 1 forms an integrated structure. A sieve plate 11 is provided on the inner side of the first grinding chamber 8, and a flow guide seat 12 is distributed on the west side of the sieve plate 11. A fixed seat 13 is provided at the bottom of the flow guide seat 12. A second motor 14 is fixedly installed on the inner side of the fixed seat 13, and the output end of the second motor 14 is connected to a rotating plate 15. A rotating roller 16 is connected to the bottom of one end of the rotating plate 15, and a second protrusion 17 is provided on the surface of the rotating roller 16. The second protrusion 17 is equidistantly distributed along the center point of the rotating roller 16, and the rotating roller 16 is symmetrically distributed along the vertical center line of the rotating plate 15. The second motor 14, the rotating plate 15, the rotating roller 16 and the second protrusion 17 form an auxiliary structure, and the auxiliary structure is provided on the inner side of the fixed seat 13.

[0023] In use, the zinc powder to be ground is placed inside the first grinding chamber 8. Then, the cylinder 3 operates, causing the top cover 2, which is fixedly connected to its top, to move longitudinally, thereby sealing the opening at the top of the machine body 1. Next, the first motor 4 operates, causing the rotating shaft 5 connected to its output end to rotate. The rotation of the shaft 5 achieves synchronous movement of the first grinding roller 6 and the second grinding roller 7. The rotation of the two grinding rollers, in conjunction with the sieve plate 11, ensures thorough grinding of the zinc powder. Multiple first protrusions 10 on the inner wall of the first grinding chamber 8 assist the first grinding roller 6 in better grinding the zinc powder. After thorough grinding, the zinc powder falls through the guide seat 12 into the annular groove at the top of the fixed seat 13. Then, the second motor 14 works to rotate the rotating plate 15 connected to its output end. The rotation of the rotating plate 15 is used to realize the synchronous movement of the rotating roller 16. Since multiple second protrusions 17 are evenly distributed along the center point on the surface of the rotating roller 16, the rotation of the two rotating rollers 16 on both sides can further realize the secondary grinding of the zinc powder after the initial grinding, so that it can reach a finer degree. After thorough grinding, the zinc powder will be exposed through the hole at the bottom of the fixed seat 13.

[0024] Specific working principle:

[0025] In use, the zinc powder to be ground is placed inside the first grinding chamber 8. Then, the cylinder 3 operates, causing the top cover 2, which is fixedly connected to its top, to move longitudinally, thereby sealing the opening at the top of the machine body 1. Next, the first motor 4 operates, causing the rotating shaft 5 connected to its output end to rotate. The rotation of the shaft 5 achieves synchronous movement of the first grinding roller 6 and the second grinding roller 7. The rotation of the two grinding rollers, in conjunction with the sieve plate 11, ensures thorough grinding of the zinc powder. Multiple first protrusions 10 on the inner wall of the first grinding chamber 8 assist the first grinding roller 6 in better grinding the zinc powder. After thorough grinding, the zinc powder passes through the guide seat 1. 2. The zinc powder falls into the annular groove at the top of the fixed base 13. Then, the second motor 14 works to make the rotating plate 15 connected to its output end rotate. The rotation of the rotating plate 15 realizes the synchronous movement of the rotating roller 16. Since multiple second protrusions 17 are evenly distributed along the center point on the surface of the rotating roller 16, the rotation of the two rotating rollers 16 on both sides can further realize the secondary grinding process of the zinc powder after the initial grinding, so that it can reach a finer degree. After the zinc powder has been fully ground, it will fall into the inner side of the collection frame 19 through the hole at the bottom of the fixed base 13, so that it can be easily removed by sliding along the slide rail 18 via the pulley 20.
