Description

Technical Field

[0001] The utility model relates to a grooved roller of an open mixing mill, belonging to the field of open mixing mills. Background Art

[0002] In the application field of open mixing mills, the traditional press roller design has certain limitations. Many press rollers in the prior art adopt a straight line design on both sides of the groove, that is, they are composed of inclined surfaces and vertical surfaces. Since the two sides are designed as straight lines, an angle will be formed at the lowest point of the groove. This angle is easy to cause material residue and is difficult to clean thoroughly, which not only affects the product quality, but also may cause damage to the equipment. The residual material may gradually accumulate during multiple processing, causing the groove shape to change, affecting the subsequent material tableting effect.

[0003] In addition, this traditional groove design is not adaptable enough when processing materials with different characteristics and processing requirements, and it is difficult to meet the needs of diversified production. For example, for some materials with high viscosity or requiring fine mixing, the straight groove cannot provide sufficient shear force and mixing effect, resulting in uneven material mixing and unstable product quality. At the same time, due to its structural limitations, when facing materials with different hardness and viscosity, it is impossible to optimize the processing process by adjusting the groove parameters, which limits the versatility and production efficiency of the equipment. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model aims to provide a grooved roller for an open mixing mill to solve the existing problems.

[0005] In order to achieve the above object, the utility model is implemented through the following technical scheme: a grooved roller of an open mixing mill, comprising:

[0006] A groove assembly, wherein the groove assembly comprises an arc portion with an inner wall on one side being an arc and a slope portion with an inner wall on the other side being an inclined portion, wherein the bottom end of the arc portion is connected to the bottom end of the slope portion, wherein the lowest point of the arc portion forms an inclined angle with the slope portion along its horizontal direction, and the inclined angle is 75 to 89 degrees;

[0007] A first roller, wherein a plurality of groove components are provided on the first roller, and the groove components are one of an integrally formed or divided design;

[0008] The second roller is arranged on the mixing mill together with the first roller. When the material passes between the first roller and the second roller, the first roller supports and preliminarily shapes the material, and the second roller performs the final flattening and shaping of the material, thereby jointly realizing the sheeting of the material.

[0009] Furthermore, the groove assembly is integrally formed, so that the groove and the first roller have higher structural strength, which can effectively withstand the extrusion and friction of the material on the groove during the refining process.

[0010] Furthermore, the groove assembly is of a split-piece design, which enables the groove to gradually adapt to different material materials during the refining process, thereby achieving a more uniform material distribution and a more efficient mixing effect.

[0011] Furthermore, the groove assembly is arranged around the axis of the roller on the outer circumferential surface of the roller in an axial direction in an equidistant or unequally spaced manner, and the spacing between the grooves is greater than or equal to 15 mm.

[0012] Furthermore, the arc portion in the groove assembly is composed of a circle with a radius of 4.5 to 5 mm.

[0013] Furthermore, an arc transition is adopted at the junction of the arc portion and the inclined portion, and the arc is a circle with a radius of 0.1 to 0.3 mm.

[0014] Furthermore, the second roller is a smooth roller, and its rotation speed is faster than that of the first roller, so as to achieve accurate sheeting and high-quality shaping of the material.

[0015] Furthermore, the first roller and the second roller rotate in opposite directions to achieve bidirectional extrusion of the material and a more uniform mixing effect.

[0016] Furthermore, the groove assembly has a depth of 1 to 2 mm and a width of 2.5 to 3.5 mm.

[0017] The beneficial effects of the utility model are:

[0018] 1. The groove in the present application is composed of an arc side and a slope side. This structural design enables the material to obtain more uniform force and more sufficient shearing effect during the tableting process, thereby effectively improving the mixing effect and tableting quality of the material, ensuring that the material thickness is uniform, and the inclined design of the groove helps the smooth flow of the material on the roller, reduces the resistance and accumulation of the material during the tableting process, and improves the working efficiency and production continuity of the open mill.

[0019] 2. This application further enhances the bidirectional extrusion and mixing effect of the material by designing the second roller as a smooth roller with a faster rotation speed than the first roller, and the rotation directions of the first roller and the second roller are opposite, so that the material can quickly reach the ideal tableting state, while improving the density and surface smoothness of the material. This design also improves the adaptability of the entire mixing mill system to different materials, can meet the tableting needs of a variety of materials, and broadens the application range of the equipment.

[0026] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0027] like Figure 1 , Figure 2 and Figure 3 As shown, the utility model provides a technical solution of a grooved roller of an open mixing mill, which includes:

[0028] A groove assembly 1, wherein the groove assembly 1 comprises an arc portion 101 with an inner wall on one side being an arc and a slope portion 102 with an inner wall on the other side being an inclined portion, wherein the bottom end of the arc portion 101 is connected to the bottom end of the slope portion 102, wherein the lowest point of the arc portion 101 forms an inclined angle with the slope portion 102 along its horizontal direction, wherein the inclined angle is 75 to 89°, wherein the inclined angle is preferably 86°;

[0029] A first roller 2, on which a plurality of groove components 1 are provided, wherein the groove components 1 are one of an integrally formed or divided design;

[0030] The second roller 3 is arranged on the mixing mill together with the first roller 2. When the material passes between the first roller 2 and the second roller 3, the first roller 2 supports and preliminarily shapes the material, and the second roller 3 finally flattens and shapes the material, thereby jointly realizing sheeting of the material.

[0031] In order to increase the wear resistance and structural strength of the groove, the groove assembly 1 is formed in one piece, so that the groove and the first roller 2 have higher structural strength and can effectively withstand the extrusion and friction of the material on the groove during the refining process.

[0032] In order to adapt to different material properties and improve the mixing effect, the groove assembly 1 is designed in a split-piece manner, which enables the groove to gradually adapt to different material properties during the mixing process, thereby achieving more uniform material distribution and more efficient mixing effect.

[0033] In order to optimize the flow and distribution of materials, the groove assembly 1 is arranged around the axis of the roller on the outer circumferential surface of the roller in an axial direction in an equidistant or unequal manner, and the spacing between the grooves is greater than or equal to 15 mm.

[0034] In order to achieve specific material guiding and shearing, the arc portion 101 in the groove assembly 1 is composed of a circle with a radius of 4.5 to 5 mm, wherein the arc side is preferably composed of a circle with a radius of 4.7.

[0035] In order to enhance the structural strength of the groove and reduce the risk of material jamming, an arc transition is adopted at the junction of the arc portion 101 and the inclined portion 102, and the arc is composed of a circle with a radius of 0.1 to 0.3 mm.

[0036] In order to achieve accurate tableting and high-quality shaping, the second roller 3 is a smooth roller, and its rotation speed is faster than that of the first roller 2, so as to achieve accurate tableting and high-quality shaping of the material.

[0037] In order to achieve a better bidirectional extrusion effect, the first roller 2 and the second roller 3 rotate in opposite directions to achieve bidirectional extrusion of the material and a more uniform mixing effect.

[0038] In order to optimize the shearing and mixing effects of the material, the groove component 1 has a depth of 1 to 2 mm and a width of 2.5 to 3.5 mm, wherein the depth is preferably 1.5 mm and the width is preferably 3 mm.

[0039] The groove in the present application is composed of an arc side and a slope side. This structural design enables the material to obtain more uniform force and more sufficient shearing effect during the tableting process, thereby effectively improving the mixing effect and tableting quality of the material, ensuring that the material thickness is uniform, and the inclined design of the groove helps the smooth flow of the material on the roller, reducing the resistance and accumulation of the material during the tableting process, and improving the working efficiency and production continuity of the mixing mill.

[0040] The present application further enhances the bidirectional extrusion and mixing effect of the material by designing the second roller 3 as a smooth roller with a faster rotation speed than the first roller 2, and the rotation directions of the first roller 2 and the second roller 3 are opposite, so that the material can quickly reach the ideal tableting state, while improving the density and surface smoothness of the material. This design also improves the adaptability of the entire mixing mill system to different materials, can meet the tableting needs of a variety of materials, and broadens the application range of the equipment.

[0041] Figure 1 It is a structural schematic diagram of the present application for an open mixing mill, in which the first roller 2 and the second roller 3 are arranged side by side inside the frame A1 of the open mixing mill through fixed structures on the left and right sides, and the groove design on the surface of the first roller 2 and the smooth surface design of the second roller 3, combined with their different rotation directions and rotation speeds, efficient mixing and precise tableting of materials are achieved, wherein the rotation direction of the first roller 2 is counterclockwise toward the inside of the open mixing mill, and the second roller 3 is clockwise toward the inside of the open mixing mill.

[0042] Figure 2 The groove is one-piece formed in the middle. Since there is no trace of splicing or combination between the one-piece groove and the roller body, the overall structure is more solid and can effectively withstand the extrusion and friction of the material on the groove during the refining process, avoiding deformation or damage of the groove, thereby extending the service life of the roller. The surface is smooth without burrs or unevenness caused by subsequent processing or splicing, which helps to reduce the residue and adhesion of materials in the groove, and there is no problem of groove falling off or damage due to loose or corrosion at the connection. Therefore, it can maintain stable performance during long-term use and reduce equipment maintenance costs and downtime.

[0043] Figure 3 The middle part is a split groove. The split groove adopts the method of installing a new sheet structure or spraying an additional coating on the basis of the original groove, and can be installed by fixing methods such as bolts, welding or gluing. The additional structure of the split groove can be customized according to different material characteristics and processing requirements. By adjusting the shape, size and material of the additional structure, the precise mixing and tableting effect of the material can be achieved to meet the diversified production needs. When the groove is worn or damaged, the additional structure can be quickly replaced to reduce equipment downtime and improve production efficiency. In addition, the design of the split groove avoids the replacement of the entire roller. Only the additional groove structure needs to be replaced or repaired, thereby reducing maintenance costs, achieving precise control of materials, and avoiding material waste. In summary, the split groove has significant advantages in enhancing adaptability, improving maintainability, improving surface performance, optimizing cost-effectiveness, enhancing structural strength, improving processing accuracy and promoting technological innovation, which can effectively improve the comprehensive performance and market competitiveness of the mixing mill.

[0044] Figure 4 The present invention shows a common V-groove design in the prior art. This V-groove is composed of an inclined surface and a vertical surface intersecting to form a sharp angle. In actual application, this angle area is prone to cause material residue, which is difficult to clean thoroughly. The residual material may not only affect the product quality, but also cause damage to the equipment, such as corrosion or wear. In addition, the design of the V-groove is not adaptable enough when processing materials with different characteristics and processing requirements, and it is difficult to meet the needs of diversified production. In contrast, the arc groove design adopted in the present application is smoother, which can effectively reduce the residue of material in the groove, improve cleaning efficiency and product quality, and enhance the adaptability and versatility of the equipment. In summary, the arc groove design of the present application has achieved significant technological progress in structure, adaptability, cleaning efficiency and quality assurance, and is an effective innovation of the prior art.
