Description

Technical Field

[0001] This invention relates to the field of horizontal sand mill technology, and more specifically to a horizontal sand mill for coating production. Background Technology

[0002] The production process of coatings involves batching, dispersion, milling, paint mixing, filtration, testing, and filling. Coatings contain powder particles, and the smaller the particles, the better the performance. Therefore, milling is necessary during the coating preparation process.

[0003] However, existing coating sand mills are difficult to maintain and clean, which increases the cost of using and maintaining the equipment. They cannot prevent coating from adhering to the inner wall of the equipment, reducing the sand milling efficiency. They are also less flexible and cannot adjust the sand milling position according to the amount of coating inside the equipment. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides a horizontal sand mill for coating production, which solves the problem of high maintenance and cleaning difficulty of existing coating sand mills, reduces the cost of equipment use and maintenance, avoids coating adhering to the inner wall of the equipment and reducing sand milling efficiency, improves the flexibility of equipment use, and allows adjustment of the sand milling position according to the amount of coating inside the equipment.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a horizontal sand mill for paint production, comprising a base plate, a mounting frame fixedly connected to the top of the base plate, a drive motor installed inside the mounting frame, a sand mill barrel fixedly connected to the top of the base plate near the drive motor, a rotating rod installed on one side of the inner wall of the sand mill barrel, the output end of the drive motor penetrating the sand mill barrel and fixedly connected to the rotating rod, sand mill plates evenly installed on the outer side of the rotating rod, an annular mesh cloth installed on the inner wall of the sand mill barrel, and positioning bolts evenly installed on the inner wall of the annular mesh cloth, the positioning bolts penetrating the annular mesh cloth and the sand mill barrel and extending into the interior of the sand mill barrel, enabling... The device facilitates the replacement of worn parts inside, ensuring long-term operation and extending its service life. An elastic rope is fixedly connected to the outer side of the annular mesh between the positioning bolts. The end of the elastic rope away from the annular mesh is fixedly connected to the grinding drum. An elastic plate is fixedly connected to the inner wall of the annular mesh near the grinding plate. Both the grinding plate and the elastic plate have an arc-shaped structure at one end, which pushes the coating adhering to the inner wall of the device towards the center during grinding, preventing the coating from adhering to the inner wall and reducing the grinding effect, thus improving the grinding efficiency. A discharge pipe is connected to the top of the grinding drum, and a feed pipe is connected to one side of the grinding drum.

[0006] Preferably, a sealing plug is installed at the end of the sand mill barrel away from the drive motor. The sealing plug penetrates into the interior of the sand mill barrel and is slidably connected to it. A handle groove is provided on the side of the sealing plug away from the sand mill barrel. A handle is fixedly connected to one side of the inner wall of the handle groove. This allows the sand mill barrel to be easily opened for replacement, repair, and cleaning of the internal parts, reducing the difficulty and cost of equipment maintenance.

[0007] Preferably, a longitudinal groove is formed on the side of the sand mill barrel near the drive motor, the longitudinal groove penetrates the sand mill barrel, the output end of the drive motor penetrates the longitudinal groove and is slidably connected to the inner wall of the longitudinal groove, a sealing plate is sleeved on the outside of the output end of the drive motor, the sealing plate is slidably connected to the sand mill barrel, and adjusting bolts are symmetrically installed on the side of the sealing plate away from the sand mill barrel, the adjusting bolts penetrate the sealing plate, which improves the flexibility of the equipment, can adjust the position of the rotating sand mill inside the equipment as needed, and can reduce the sand milling height when there is less paint inside the equipment, thereby improving the sand milling efficiency of the paint.

[0008] Preferably, a support spring is fixedly connected to the bottom inner side of the mounting frame, and a support plate is fixedly connected to the top of the support spring. The support plate is slidably connected to the inner wall of the mounting frame. The drive motor is fixedly connected to the top of the support plate. A control groove is provided inside the rotating rod. A wear-resistant block is slidably connected to the inner wall of the control groove. An arc-shaped notch is provided on the outer side of the wear-resistant block. One end of the sanding plate extends into the control groove and is slidably connected to the wear-resistant block. A magnetic suction groove is provided inside the wear-resistant block. The magnetic suction groove penetrates the wear-resistant block. A magnet is fixedly connected inside the magnetic suction groove. One end of the sanding plate extending into the control groove is made of magnetic metal. One end of the wear-resistant block is fixedly connected to the control groove through a torsion spring. This improves the intelligence of the equipment, enabling the sanding plates in other positions to automatically retract after the rotating rod and sanding plate are lowered, ensuring that all sanding plates extend to the outside of the rotating rod with the same length, thus preventing the sanding plates from colliding with the inner wall of the sanding barrel during the sanding process.

[0009] Preferably, a drive rod is fixedly connected to the end of the wear-resistant block away from the torsion spring. An arc-shaped plate is evenly installed on the outer side of the drive rod. A heat-conducting rod is evenly installed on the outer side of the rotating rod near the arc-shaped plate. The heat-conducting rod extends into the interior of the control groove and is slidably connected to the rotating rod. The heat-conducting rod is slidably connected to the arc-shaped plate. A heat dissipation groove is symmetrically opened at the end of the heat-conducting rod extending to the outside of the rotating rod. A heat dissipation plate is rotatably connected to one side of the inner wall of the heat dissipation groove, which improves the heat dissipation capacity of the equipment and can reduce the internal temperature of the rotating rod during the operation of the equipment, avoiding damage caused by excessive temperature during the use of the sand mill.

[0010] This invention provides a horizontal sand mill for coating production. It has the following beneficial effects:

[0011] (I) This horizontal sand mill for paint production allows grinding steel balls to be added to the inside of the sand mill barrel by opening the sealing plug. The sealing plug is then moved towards the sand mill barrel until it blocks the barrel. Paint liquid is then introduced into the sand mill barrel through the feed pipe. The drive motor drives the rotating rod and the sand milling plate to rotate. During the rotation, the sand milling plate grinds the paint liquid inside the sand mill barrel. After grinding, the paint liquid is discharged from the discharge pipe. The inside of the sand mill barrel can be cleaned after opening the sealing plug. This allows for easy opening of the sand mill barrel to replace, repair, and clean the internal parts, reducing the difficulty and cost of equipment maintenance.

[0012] (II) The horizontal sand mill used for coating production gradually moves the grinding plate closer to the elastic plate during rotation. The grinding plate continues to rotate, pushing the elastic plate to move. The annular mesh is bent and concave by the elastic plate. The coating liquid adhering to the surface of the annular mesh on the inner wall of the sand mill is pulled to the middle position of the sand mill. The annular mesh stretches and deforms the elastic rope. The grinding plate gradually pushes and deforms the elastic plate, and then it detaches from the surface of the elastic plate. The elastic plate is no longer pushed by the grinding plate. The elastic rope pulls the annular mesh back to the initial position. This can push the coating adhering to the inner wall of the equipment to the middle position of the equipment for sanding during the sanding process, avoiding the coating adhering to the inner wall of the equipment and reducing the sanding effect, thus improving the sanding effect.

[0013] (III) The horizontal sand mill used for coating production can remove the positioning bolts after the annular mesh is deformed by the elastic plate, replace the annular mesh inside the sand mill barrel with a new one, and then fix the annular mesh back to the sand mill barrel using the positioning bolts. This allows for easy replacement of worn parts inside the equipment, ensuring that the equipment can work for a long time and improving its service life.

[0014] (iv) The horizontal sand mill used for paint production drives the motor and rotating rod to move downward along one side of the sand mill barrel. The output end of the drive motor slides downward along the longitudinal groove. The sealing plate always blocks the longitudinal groove as the drive motor moves downward. After rotating the adjusting bolt until it is pressed against the sand mill barrel, the sealing plate is fixed on the sand mill barrel. After the drive motor starts, it drives the rotating rod and sand mill plate to rotate at a lower position inside the sand mill barrel for sand milling. This improves the flexibility of the equipment and allows the position of the rotating sand mill inside the equipment to be adjusted as needed. When there is less paint inside the equipment, the sand milling height can be reduced, which can improve the sand milling efficiency of the paint.

[0015] (V) The horizontal sand mill used for paint production uses a torsion spring to push the wear-resistant block to rotate, pushing the sand mill plate outwards from the rotating rod. The rotating rod and sand mill plate move downwards, and after the sand mill plate contacts the inner bottom of the sand mill barrel, it is squeezed against the inner wall of the sand mill barrel. The bottom sand mill plate is squeezed into the control slot. The sand mill plate pushes the wear-resistant block to rotate clockwise and then continues to move inwards from the rotating rod. The magnetic block attracts the sand mill plates in other positions to move inwards from the rotating rod and is attracted and fixed to the wear-resistant block. This improves the intelligence of the equipment. After the rotating rod and sand mill plate are lowered, the sand mill plates in other positions can be automatically retracted to ensure that the length of all sand mill plates extending to the outside of the rotating rod is the same, avoiding damage caused by the sand mill plates colliding with the inner wall of the sand mill barrel during the sand milling process.

[0016] (vi) The horizontal sand mill used for coating production generates heat during the sand milling process through the rotating rod and the sand milling plate. The heat is transferred to the inside of the rotating rod. The heat-conducting rod absorbs the heat inside the rotating rod and its temperature rises. During the descent of the sand milling plate, the wear-resistant block is pushed to rotate. The wear-resistant block drives the arc plate to rotate. The arc plate pushes the heat-conducting rod outward from the rotating rod. The heat dissipation plate moves to the outside of the rotating rod along with the heat-conducting rod. During the rotation of the rotating rod, the heat dissipation plate deflects away from the heat-conducting rod. The heat on the heat-conducting rod is transferred to the inside of the coating. The heat dissipation plate increases the heat dissipation area of ​​the heat-conducting rod and improves the heat dissipation capacity of the equipment. It can reduce the internal temperature of the rotating rod during the operation of the equipment and avoid damage caused by excessive temperature during the use of the sand milling equipment.

Detailed Implementation

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0026] Example 1

[0027] Please see Figures 1-3 This invention provides a technical solution: a horizontal sand mill for paint production, comprising a base plate 1, a mounting frame 2 fixedly connected to the top of the base plate 1, a drive motor 3 installed inside the mounting frame 2, a sand mill 4 fixedly connected to the top of the base plate 1 near the drive motor 3, a rotating rod 5 installed on one side of the inner wall of the sand mill 4, the output end of the drive motor 3 passing through the sand mill 4 and fixedly connected to the rotating rod 5, sand mill plates 6 evenly installed on the outer side of the rotating rod 5, and an annular mesh 7 installed on the inner wall of the sand mill 4. The wall is uniformly equipped with positioning bolts 8, which pass through the annular mesh 7 and the grinding barrel 4 and extend into the interior of the grinding barrel 4. An elastic rope 9 is fixedly connected to the outer side of the annular mesh 7 between the positioning bolts 8. The end of the elastic rope 9 away from the annular mesh 7 is fixedly connected to the grinding barrel 4. An elastic plate 10 is fixedly connected to the inner wall of the annular mesh 7 near the grinding plate 6. One end of the grinding plate 6 and the elastic plate 10 are both arc-shaped. The top of the grinding barrel 4 is connected to the discharge pipe 11, and one side of the grinding barrel 4 is connected to the feed pipe 12.

[0028] A sealing plug 13 is installed at the end of the sanding barrel 4 away from the drive motor 3. The sealing plug 13 penetrates into the interior of the sanding barrel 4 and is slidably connected to the sanding barrel 4. A handle groove 14 is provided on the side of the sealing plug 13 away from the sanding barrel 4. A handle 15 is fixedly connected to one side of the inner wall of the handle groove 14.

[0029] In use, open the sealing plug 13, add grinding steel balls into the sand mill 4, move the sealing plug 13 towards the sand mill 4 until the sealing plug 13 blocks the sand mill 4, and let the paint liquid enter the sand mill 4 from the feed pipe 12. The drive motor 3 drives the rotating rod 5 and the sand mill plate 6 to rotate. During the rotation, the sand mill plate 6 sands the paint liquid inside the sand mill 4. After sanding, the paint liquid is discharged from the discharge pipe 11. After opening the sealing plug 13, the inside of the sand mill 4 can be cleaned. It is convenient to open the sand mill 4 to replace, repair and clean the internal parts of the sand mill 4, which reduces the difficulty of equipment maintenance and reduces the maintenance cost of the equipment.

[0030] As the grinding plate 6 rotates, it gradually approaches the elastic plate 10. The grinding plate 6 continues to rotate, pushing the elastic plate 10 to move. The annular mesh 7 is bent and concave by the elastic plate 10. The paint liquid adhering to the surface of the annular mesh 7 on the inner wall of the grinding barrel 4 is pulled towards the middle position of the grinding barrel 4. The annular mesh 7 stretches and deforms the elastic rope 9. The grinding plate 6 gradually pushes the elastic plate 10 to deform and detaches it from the surface of the elastic plate 10. The elastic plate 10 is no longer pushed by the grinding plate 6. The elastic rope 9 pulls the annular mesh 7 to the initial position. This can push the paint adhering to the inner wall of the equipment towards the middle position of the equipment for grinding during the grinding process, avoiding the paint adhering to the inner wall of the equipment and reducing the grinding effect, thus improving the grinding effect.

[0031] After the ring mesh 7 is deformed by the elastic plate 10, the positioning bolt 8 is removed, and a new ring mesh 7 is replaced inside the sand mill 4. The positioning bolt 8 is then used to fix the ring mesh 7 to the sand mill 4. This allows for easy replacement of worn parts inside the equipment, ensuring that the equipment can work for a long time and improving its service life.

[0032] Example 2

[0033] Please see Figures 1-7 The present invention provides a technical solution: Based on embodiment 1, a longitudinal groove 16 is provided on the side of the sand grinding barrel 4 near the drive motor 3. The longitudinal groove 16 penetrates the sand grinding barrel 4. The output end of the drive motor 3 penetrates the longitudinal groove 16 and is slidably connected to the inner wall of the longitudinal groove 16. A sealing plate 17 is sleeved on the outside of the output end of the drive motor 3.

[0034] The sealing plate 17 is slidably connected to the grinding barrel 4. Adjusting bolts 18 are symmetrically installed on the side of the sealing plate 17 away from the grinding barrel 4, and the adjusting bolts 18 penetrate the sealing plate 17.

[0035] A support spring 19 is fixedly connected to the bottom inner side of the mounting frame 2, and a support plate 20 is fixedly connected to the top of the support spring 19. The support plate 20 is slidably connected to the inner wall of the mounting frame 2, and the drive motor 3 is fixedly connected to the top of the support plate 20.

[0036] The rotating rod 5 has a control groove 21 inside, and a wear-resistant block 22 is slidably connected to the inner wall of the control groove 21. An arc-shaped notch is provided on the outer side of the wear-resistant block 22. One end of the abrasive plate 6 extends into the interior of the control groove 21 and is slidably connected to the wear-resistant block 22.

[0037] The wear-resistant block 22 has a magnetic groove 23 inside, which runs through the wear-resistant block 22. A magnet block 24 is fixedly connected inside the magnetic groove 23. The end of the abrasive plate 6 that extends into the control groove 21 is made of magnetic metal. One end of the wear-resistant block 22 is fixedly connected to the control groove 21 by a torsion spring 25.

[0038] A drive rod 26 is fixedly connected to the end of the wear-resistant block 22 away from the torsion spring 25. Arc-shaped plates 27 are evenly installed on the outer side of the drive rod 26. Heat-conducting rods 28 are evenly installed on the outer side of the rotating rod 5 near the arc-shaped plates 27. The heat-conducting rods 28 penetrate into the interior of the control groove 21 and are slidably connected to the rotating rod 5. The heat-conducting rods 28 are slidably connected to the arc-shaped plates 27. A heat dissipation groove 29 is symmetrically opened at the end of the heat-conducting rods 28 extending to the outside of the rotating rod 5. A heat dissipation plate 30 is rotatably connected to one side of the inner wall of the heat dissipation groove 29.

[0039] In use, the drive motor 3 and the rotating rod 5 are moved downward along one side of the sanding barrel 4. The output end of the drive motor 3 slides downward along the longitudinal groove 16. The sealing plate 17 always blocks the longitudinal groove 16 as the drive motor 3 moves downward. After rotating the adjusting bolt 18 until it is pressed against the sanding barrel 4, the sealing plate 17 is fixed on the sanding barrel 4. After the drive motor 3 is started, it drives the rotating rod 5 and the sanding plate 6 to rotate at a lower position inside the sanding barrel 4 for sanding. This improves the flexibility of the equipment and allows the position of the rotating sanding inside the equipment to be adjusted as needed. When there is less paint inside the equipment, the sanding height can be reduced, which can improve the sanding efficiency of the paint.

[0040] The torsion spring 25 pushes the wear-resistant block 22 to rotate, pushing the sanding plate 6 outwards towards the rotating rod 5. The rotating rod 5 and the sanding plate 6 move downwards. After the sanding plate 6 contacts the bottom inner side of the sanding barrel 4, it is squeezed against the inner wall of the sanding barrel 4. The bottom sanding plate 6 is squeezed into the control groove 21. The sanding plate 6 pushes the wear-resistant block 22 to rotate clockwise and continues to move inwards towards the rotating rod 5. The magnet block 24 attracts the remaining sanding plates 6 to move inwards towards the rotating rod 5 and is attracted and fixed to the wear-resistant block 22. This improves the intelligence of the equipment. After the rotating rod 5 and the sanding plate 6 are lowered, the remaining sanding plates 6 can be automatically retracted to ensure that the length of all sanding plates 6 extending to the outside of the rotating rod 5 is the same, avoiding damage caused by the sanding plates 6 colliding with the inner wall of the sanding barrel 4 during the sanding process.

[0041] During the sanding process, the rotating rod 5 and the grinding plate 6 generate heat, which is transferred to the interior of the rotating rod 5. The heat-conducting rod 28 absorbs the heat from the interior of the rotating rod 5 and its temperature rises. As the grinding plate 6 descends, it pushes the wear-resistant block 22 to rotate. The wear-resistant block 22 drives the arc plate 27 to rotate. The arc plate 27 pushes the heat-conducting rod 28 outward from the rotating rod 5. The heat dissipation plate 30 moves to the outside of the rotating rod 5 along with the heat-conducting rod 28. During the rotation of the rotating rod 5, the heat dissipation plate 30 deflects away from the heat-conducting rod 28. The heat on the heat-conducting rod 28 is transferred to the interior of the coating. The heat dissipation plate 30 increases the heat dissipation area of ​​the heat-conducting rod 28, improves the heat dissipation capacity of the equipment, and can reduce the internal temperature of the rotating rod 5 during the operation of the equipment, avoiding damage caused by excessive temperature during the use of the sanding equipment.

[0042] Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art or related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.
