[0002] The roller mixer is mainly suitable for rolling, mixing, homogenizing, crushing and plasticizing raw materials such as fly ash, clay and coal gangue, which can significantly improve the comprehensive performance of the raw materials. The roller mixer has a wide range of applications and is suitable for building materials, refractory materials, chemicals, casting and other industries.

[0003] The structure of a roller mixer is relatively simple, primarily utilizing a pair of rollers that rely on gravity to crush the material. These rollers rotate around the axis of the trough while rolling. The production efficiency of existing roller mixers relies primarily on the speed and weight of the rollers. However, the mixing method employed by roller mixers requires a limited rotational speed, as the centrifugal force is too high and the rollers are easily thrown out. Furthermore, the rollers should be neither too heavy nor too heavy, making repair and maintenance inconvenient. Consequently, the production efficiency of existing roller mixers is limited and needs to be improved. Utility Model Content

An elastic component is provided between the bottom surface of the mounting plate and the upper surface of the connection between the second rotating shaft of the connecting plate. The force of the elastic component presses the connecting plate and the roller downward. An inclined inner scraper is provided at the bottom of the center frame plate. The inner scraper can scrape and push the material in the trough to the outside. The upper surface of the center frame plate is detachably connected to a fixing frame. The fixing frame is connected to an outer scraper. The outer scraper can flip the material in the trough and concentrate it on the movement trajectory of the roller.

[0006] Preferably, the outer scraper consists of an integrally formed plane opening and a rolled-up opening, the plane opening abuts against the bottom of the material trough, the rolled-up opening is higher than the plane opening, and corresponds to and is above the movement trajectory of the roller, and the width of the plane opening is greater than the width of the rolled-up opening.

The bottom of the trough 1 is provided with a plurality of support legs 15. The drive assembly is provided at the bottom of the trough 1. The main shaft 14 rotates through the center position of the trough 1, and the lower end is connected to the output end of the drive assembly, and the upper end is connected to the bottom of the center frame plate 9. The left and right side walls of the center frame plate 9 are respectively provided with a first rotating shaft 4. The center frame plate 9 is connected to the left and right side walls. The side walls of one end of the connecting plate 10 are rotatably connected through the first rotating shaft 4, and the side walls of the other end of the connecting plate 10 are rotatably connected to a pair of rollers 2 through the second rotating shaft 8. The first rotating shaft 4, the connecting plate 10, the second rotating shaft 8 and the rollers 2 on the left and right sides of the center frame 9 are symmetrical with each other. The left and right side walls of the center frame 9 are respectively provided with mounting plates 3. An elastic component is provided between the bottom surface of the mounting plate 3 and the upper surface of the connection point of the second rotating shaft 8 of the connecting plate 10. The force of the elastic component presses the connecting plate 10 and the roller 2 downward. 9 is provided with an inclined inner scraper 11 at the bottom, and the inner scraper 11 can scrape and push the material in the trough 1 to the outside. The upper surface of the central frame plate 9 is detachably connected to the fixing frame 7, and the fixing frame 7 is connected to the outer scraper 6. The outer scraper 6 can turn over the material in the trough 1 and concentrate it on the motion trajectory of the roller 2; the outer scraper 6 is composed of an integrally formed plane opening 62 and a roll-up opening. The plane opening 62 is in contact with the bottom of the trough 1, and the roll-up opening is higher than the plane opening 62, and corresponds to the movement of the roller 2. Above the track, the width of the plane opening 62 is greater than the width of the rolled-up opening; the elastic component adopts a compression spring 16, the upper end of the compression spring 16 is connected to the lower bottom surface of the mounting plate 3, and the lower end is connected to the upper surface of the connecting plate 10 corresponding to the position of the second rotating shaft 8, and the compression spring 16 is in a compressed state; the driving component includes a motor 12 and a reducer 13, the motor 12 is fixed to the ground and is connected to the lower end of the main shaft 14 through the reducer; the upper end of the fixing frame 7 is detachably connected to the upper surface of the center frame plate 9 by a screw 5.

[0019] The detailed connection means are well-known in the art. The following mainly introduces the working principle and process, which are as follows:

[0020] According to the instruction manual Figure 1-3It can be seen that when the present invention is working, the driving component drives the main shaft 14 to rotate. The main shaft 14 is connected to the center position of the bottom of the material trough 1 through a bearing and is sealed. The rotation of the main shaft 14 drives the center frame plate 9 to rotate, thereby driving the connecting plate 10 connected to the first rotating shaft 4 and the roller 2 connected to the connecting plate 10 to rotate around the axis of the material trough 1. At the same time, the roller 2 rolls and moves, thereby crushing, crushing and mixing the material in the material trough 1. The first rotating shaft 4, connecting plate 10, second rotating shaft 8 and roller 2 on the left and right sides of the center frame plate 9 are centrally symmetrical to ensure the stability of the movement of the roller 2. Since an elastic component is provided between the mounting plate 3 and the connecting plate 10, the force of the elastic component presses the connecting plate 10 and the roller 2 downward, thereby increasing the crushing effect of pushing the material and improving work efficiency. At the same time, the inner scraper 11 can scrape the material to the outer ring, and the outer scraper 6 can flip the material in the trough 1 and concentrate it on the movement trajectory of the roller 2. In the prior art, the materials on both sides of the movement trajectory of the roller 2 can only enter the movement trajectory of the roller 2 through multiple flippings, while in the utility model, the roller 2 can crush and mix most of the materials each time, thereby improving work efficiency.

[0021] Among them, the outer scraper 6 is composed of an integrally formed plane opening 62 and a rolled-up opening. The plane opening 62 is in contact with the bottom of the material trough 1, and the rolled-up opening is higher than the plane opening 62, and corresponds to and is above the movement trajectory of the roller 2. The width of the plane opening 62 is greater than the width of the rolled-up opening. The plane opening 62 ensures the scooping of the material, and the rolled-up opening turns and concentrates the material, ensuring that the roller 2 can crush and mix most of the material each time, thereby improving work efficiency.

[0022] Among them, the elastic component adopts a compression spring 16, the upper end of the compression spring 16 is connected to the lower bottom surface of the mounting plate 3, and the lower end is connected to the upper surface of the connecting plate 10 corresponding to the position of the second rotating shaft 8. The compression spring 16 is in a compressed state and can exert a downward force on the roller 2. The compression spring 16 can meet slight axial bending without affecting the overall use effect. It is simple and convenient to install and easy to repair and maintain.

[0023] The drive assembly includes a motor 12 and a reducer 13. The motor 12 is fixed to the ground and connected to the lower end of the main shaft 14 through the reducer. In addition, the upper end of the fixing frame 7 is detachably connected to the upper surface of the center frame plate 9 by screws 5, which facilitates the replacement of the outer scraper 6.

[0024] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
