Description

Technical Field

[0001] The utility model relates to the technical field of grinding wheel production, in particular to a device for uniformly mixing raw materials for grinding wheel production. Background Technique

[0002] A grinding wheel, also known as a vitrified abrasive tool, is a vitrified abrasive tool in which ordinary abrasives are solidified into a certain shape (mostly circular with a through hole in the center) by a binder and have a certain strength. It generally consists of abrasives, binders, and pores, and these three parts are often referred to as the three elements of vitrified abrasive tools. The grinding wheel is the most widely used and most widely applied abrasive tool. When in use, it rotates at a high speed and can be used for rough grinding, semi-precise grinding, and precise grinding, as well as grooving and cutting of the outer circle, inner circle, plane, and various profiles of metal or non-metal workpieces. The characteristics of the grinding wheel are mainly determined by factors such as abrasives, grit size, binders, hardness, structure, shape, and size. When producing grinding wheels, various raw materials need to be placed inside the mixing tank for mixing.

[0003] In the prior art, the conventional device for mixing raw materials for grinding wheel production lacks a crushing function during use. There are large-sized condensates in the raw materials, resulting in poor subsequent mixing effects. Moreover, the raw materials are all piled up at a certain place inside the tank and then stirred by a single stirring component, causing the mixing of raw materials to consume a large amount of time, with low work efficiency and uneven mixing, making it inconvenient to use.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] Please refer to Figures 1 - 3 , the present invention discloses a device for uniformly mixing raw materials for grinding wheel production, including support legs 1. There are two support legs 1 arranged on the left and right. Rotating mechanisms 2 are arranged at positions near the upper side of the support legs 1. A tank body 3 is fixedly installed between the left and right rotating mechanisms 2. The cross-section of the tank body 3 near the lower side is a conical structure, so that the raw materials in the tank body 3 can flow to the turning mechanism 12. A feeding hopper 4 is installed at a position near the left side of the upper surface of the tank body 3, and a sealing cover 5 is installed on the upper surface of the feeding hopper 4 by threading.

A spreading plate 10 is arranged on the transmission rod 7 below the deflector 8. A stirring mechanism 11 is fixedly installed on the outer surface of the transmission rod 7 near the lower side. A turning mechanism 12 is arranged between the lower surface of the transmission rod 7 and the inner wall of the lower side of the tank body 3. A discharge valve 13 is fixedly installed on the lower surface of the turning mechanism 12.

[0020] Specifically, the rotating mechanism 2 includes a second motor 201, a rotating shaft 202 and a fixed block 203. The second motor 201 is fixedly installed on the support leg 1. A rotating shaft 202 is fixedly installed on the output shaft of the second motor 201, and the rotating shaft 202 is fixedly connected to the side wall of the tank body 3 through the fixed block 203.

[0021] In this embodiment, the left and right synchronous second motor 201 drives the rotating shaft 202 to rotate. The rotating shaft 202 drives the tank body 3 to swing back and forth through the fixing block 203. The front and back rotation range of the tank body 3 is 0-60 degrees. A through hole is provided on the corresponding support leg 1 of the rotating shaft 202.

[0022] Specifically, the cross-section of the guiding hopper 8 is a conical structure with openings at the top and bottom.

[0023] In this embodiment, the guiding hopper 8 enables the added raw materials to accurately flow to the spreading plate 10.

[0024] Specifically, the crushing mechanism 9 includes a filter screen plate 901, through holes 902, and crushing blades 903. The filter screen plate 901 is fixedly installed on the inner wall of the guiding hopper 8, and through holes 902 are provided at positions corresponding to the transmission rod 7 on the filter screen plate 901. Crushing blades 903 are arranged on the transmission rod 7 above the filter screen plate 901.

[0025] In this embodiment, the filter screen plate 901 filters large particle condensates in the raw materials poured into the feeding hopper 4. The crushing blades 903 rotate with the transmission rod 7 to crush the large particle condensates, making the raw material particles smaller.

[0026] Specifically, the stirring mechanism 11 includes a cross bar 111 and stirring blades 112. The cross bar 111 is fixedly installed on the left and right sides of the transmission rod 7, and stirring blades 112 are uniformly arranged on the lower surface of the cross bar 111.

[0027] In this embodiment, the cross bar 111 rotates with the transmission rod 7, causing the cross bar 111 to drive the stirring blades 112 to rotate, and the stirring blades 112 stir the raw materials in the tank body 3.

[0028] Specifically, the turning mechanism 12 includes a feeding cylinder 121, a feeding port 122, and a spiral feeding rod 123. The feeding cylinder 121 is fixedly embedded in the lower side wall of the tank body 3. The lower surface of the feeding cylinder 121 is connected to the discharge valve 13. Feeding ports 122 are provided on the front and back side walls of the feeding cylinder 121 at positions corresponding to the inner wall of the lower side of the tank body 3. A spiral feeding rod 123 is fixedly installed on the lower surface of the corresponding transmission rod 7 of the feeding cylinder 121, and the spiral feeding rod 123 is inserted into the feeding cylinder 121.

[0029] In this embodiment, the feeding port 122 allows the raw materials on the lower side of the tank body 3 to enter the feeding cylinder 121. Then, as the spiral feeding rod 123 rotates with the transmission rod 7, the spiral feeding rod 123 drives the raw materials at the bottom to turn upward and is discharged from the upper side of the feeding cylinder 121, turning up and down reciprocally to promote the mixing of the raw materials.

[0030] In use, the output shaft of the first motor 6 drives the transmission rod 7 to rotate. The raw materials used in the production of grinding wheels are poured into the tank body 3 through the feeding hopper 4. The raw materials will be filtered by the filter screen plate 901 in the crushing mechanism 9 for the large-particle condensates in the raw materials poured from the feeding hopper 4. The crushing blades 903 rotate with the transmission rod 7 to break the large-particle condensates, making the raw material particles smaller. The raw materials falling from the filter screen plate 901 flow through the diversion hopper 8 to the spreading plate 10. The cross bar 111 rotates with the transmission rod 7, driving the stirring blades 112 to rotate. The stirring blades 112 stir the raw materials in the tank body 3. Then, in the turning mechanism 12, the transmission rod 7 drives the spreading plate 10 to rotate, and the spreading plate 10 evenly spreads the raw materials in the tank body 3, making the raw material particles small and evenly distributed, which is beneficial for subsequent stirring and mixing. Through the feeding port 122 in the stirring mechanism 11, the raw materials at the lower side of the tank body 3 enter the feeding cylinder 121. Then, the spiral feeding rod 123 rotates with the transmission rod 7, driving the raw materials at the bottom to turn upward and be discharged from the upper side of the feeding cylinder 121, turning up and down reciprocally to promote the mixing of the raw materials. And in the rotating mechanism 2, the left and right synchronous second motor 201 drives the rotating shaft 202 to rotate. The rotating shaft 202 drives the tank body 3 to swing back and forth through the fixing block 203, making the mixing of the raw materials more efficient and uniform, which is beneficial for use. After the mixing is completed, the first motor 6 drives the transmission rod 7 to rotate in the reverse direction, and the transmission rod 7 drives the spiral feeding rod 123 to rotate in the reverse direction. The discharge valve 13 is opened to discharge the raw materials.

[0031] In summary, the device for evenly mixing the raw materials for grinding wheel production can break the coagulated raw materials, evenly spread the raw materials in the tank body 3, which is beneficial for subsequent stirring and mixing. It can turn the raw materials at the bottom of the tank body 3 to the upper side position of the tank body 3, and increase the function of the tank body 3 swinging back and forth reciprocally, making the mixing of the raw materials more efficient and uniform, which is beneficial for use.
