Description

Technical Field

[0001] This invention relates to the field of mixer technology, specifically to a mixer feeding premixing device. Background Technology

[0002] A mixer is a specialized processing equipment used in industrial production for mixing and homogenizing materials. It relies on the rotation of internal mixing components to disturb the materials and achieve the blending and mixing of various raw materials. In the material processing process, mixers often need to mix multiple raw materials. As a key supporting component to improve the uniformity of mixing, the feeding premixing equipment can complete the preliminary mixing before the raw materials enter the mixing chamber. This helps to optimize the material feeding state and ensure the smooth operation of subsequent processing operations of the mixer.

[0003] Existing mixer-feed premixing equipment typically has a feed inlet at a fixed position on one side of the mixer. Various raw materials are fed into the equipment from a single position for premixing. However, because the feed position is fixed and the raw materials are concentrated and piled up, the diffusion range of the raw materials is limited, making it difficult for different types of materials to mix evenly. The premixing effect is poor, which to some extent reduces the quality and efficiency of material processing and production, and cannot well meet the actual needs of industrial fine mixing.

Detailed Implementation

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0025] Reference Figures 1-7 This is the first embodiment of the present invention. This embodiment provides a mixer feeding premixing device. The mixer feeding premixing device includes a processing box 1. A base 2 is provided below the processing box 1. Strip plates 3 are fixedly connected to both sides of the processing box 1. Support columns 4 are vertically installed at the bottom of both ends of the strip plates 3. The bottom ends of the support columns 4 are connected to the base 2. A premixing chamber 10 is provided inside the processing box 1. A mixing component 11 for mixing different kinds of raw materials evenly is provided inside the premixing chamber 10.

[0026] During use, the base 2 supports the entire equipment, and together with the strip plate 3 and the support column 4, it ensures that the processing box 1 is placed stably and the force is even. The raw materials are uniformly transported to the premixing chamber 10 inside the processing box 1. Then, the stirring component 11 stirs and agitates the various raw materials, thereby achieving the initial mixing of the raw materials and completing the basic operation of material premixing processing.

[0027] The top of the processing box 1 is provided with a box top cover 5. The top of the inner cavity of the box top cover 5 is provided with a mounting shell 7. The bottom of both ends of the mounting shell 7 is fixedly connected with a material trough 6. The material trough 6 is connected to both sides of the inner wall of the box top cover 5. The inside of the material trough 6 is provided with a feeding component 8 for evenly sprinkling the raw materials into the premixing chamber 10. The top of the box top cover 5 is provided with a hopper 12. The outside of the hopper 12 is provided with an anti-blocking component 13 to facilitate breaking the accumulation of raw materials through efficient vibration.

[0028] During use, the staff puts the raw materials required for processing into the hopper 12. Then, the anti-blocking component 13 generates vibration to break up the accumulation of raw materials, thereby preventing the raw materials from blocking the discharge position of the hopper 12. The raw materials fall smoothly into the mounting shell 7 and are diverted to the material tanks 6 on both sides. Then, the feeding component 8 evenly sprinkles the raw materials in the material tanks 6 into the premixing chamber 10, thereby expanding the distribution range of raw materials, avoiding the problem of concentrated accumulation of raw materials, and improving the premixing uniformity. Example

[0029] Reference Figures 1-5 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0030] Specifically, the stirring assembly 11 includes a third drive shaft 111 disposed inside the premixing chamber 10. The top end of the third drive shaft 111 is rotatably connected to the top cover 5 of the chamber. Multiple stirring paddles 113 are symmetrically installed on the outer side of the third drive shaft 111. A second drive motor 112 is disposed between the material tanks 6. The second drive motor 112 is fixedly installed inside the top cover 5 of the chamber. The top end of the third drive shaft 111 passes through the top cover 5 of the chamber and is connected to the output end of the second drive motor 112.

[0031] In use, the second drive motor 112 can drive the third drive shaft 111 to rotate at a constant speed. The rotating third drive shaft 111 then drives multiple sets of stirring paddles 113 on the outside to rotate synchronously, thereby continuously stirring and mixing the various raw materials scattered inside the premixing chamber 10, so that different kinds of raw materials can be quickly blended and mixed, further improving the premixing effect of the equipment.

[0032] Specifically, the anti-blocking component 13 includes a support plate 131 disposed at the top of the inner cavity of the hopper 12. The support plate 131 is connected to both sides of the inner wall of the hopper 12. A vibration motor 132 is fixedly installed on the top of the support plate 131. Limiting plates 137 are fixedly connected to both sides of the hopper 12. An L-shaped plate 134 is provided below the limiting plate 137. The bottom of the L-shaped plate 134 is connected to the top cover 5 of the box. Guide posts 135 are vertically installed at the bottom of both ends of the limiting plate 137. The bottom end of the guide post 135 extends through to the outside of the L-shaped plate 134. A spring 136 is coaxially provided on the periphery of the guide post 135. The spring 136 is connected to the L-shaped plate 134 and the limiting plate 137 respectively. A telescopic material tube 133 is connected to the bottom of the hopper 12. The bottom end of the telescopic material tube 133 is connected to the mounting shell 7.

[0033] During use, the vibrating motor 132 generates high-frequency vibration and transmits it to the entire hopper 12, thereby breaking up the raw materials accumulated inside the hopper 12 and preventing the raw materials from clogging the discharge port. At the same time, the guide column 135, together with the spring 136, limits and buffers the hopper 12 during the vibration process to prevent the vibration amplitude from being too large and causing the equipment structure to loosen. The telescopic material tube 133 can adapt to the slight vibration displacement of the hopper 12 to ensure that the raw materials are stably transported to the inside of the mounting shell 7.

[0034] Specifically, the bottom of the processing box 1 is provided with a discharge port 14, the bottom of the premixing chamber 10 is connected to the outside through the discharge port 14, a solenoid valve is installed inside the discharge port 14, and the top of the processing box 1 and the bottom of the box cover 5 are provided with a docking part 9, which are connected by bolts.

[0035] During use, after the raw materials have completed premixing, the operator can control the solenoid valve inside the discharge port 14 to open, and the material that has been mixed inside the premixing chamber 10 will be discharged from the discharge port 14. This makes it easier for the operator to transport the premixed raw materials to the mixing equipment. The docking part 9 is fastened with bolts, which can realize the closed assembly of the processing box 1 and the box top cover 5. It is easy to disassemble and assemble, and it is convenient for the operator to inspect and maintain the internal components of the equipment later. Example

[0036] Reference Figures 4-7 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0037] Specifically, the feeding assembly 8 includes a distribution plate 81 disposed inside the material tank 6. A first drive shaft 82 is provided on both sides of the distribution plate 81. The first drive shaft 82 is rotatably connected to the distribution plate 81 and the inner wall of the material tank 6, respectively. A spiral auger 83 is fixedly installed on the outer side of the first drive shaft 82. The bottom of the inner cavity of the material tank 6 is provided with intermittently spaced discharge ports 84. The top of the premixing chamber 10 is connected to the inside of the material tank 6 through the discharge ports 84. A distribution block 811 is fixedly installed at the bottom of the inner cavity of the mounting shell 7.

[0038] During use, the raw materials fall into the housing 7 through the telescopic material pipe 133. Then, the material is evenly distributed to the material tanks 6 on both sides by the material distribution block 811. At the same time, the material distribution plate 81 divides and guides the material. The first drive shaft 82 drives the spiral auger 83 to rotate at a constant speed, thereby smoothly conveying the raw materials in the material tank 6. The raw materials are evenly sprinkled into the premixing chamber 10 through the equally spaced drop ports 84. This expands the material drop area and avoids the accumulation of raw materials, laying the foundation for subsequent mixing and premixing operations.

[0039] Specifically, a quadrilateral frame 85 is fixedly connected to both sides of the top cover 5. A second drive shaft 86 is provided inside the quadrilateral frame 85. One end of the first drive shaft 82 passes through the quadrilateral frame 85 and is fixedly installed with a driven bevel gear 88. A driving bevel gear 87 is provided on one side of the driven bevel gear 88. The driving bevel gear 87 is fixedly installed on the outside of the second drive shaft 86. One side of the driving bevel gear 87 is meshed with the driven bevel gear 88. A first drive motor 89 is fixedly installed on one side of the quadrilateral frame 85. One end of the second drive shaft 86 passes through the quadrilateral frame 85 and is connected to the output end of the first drive motor 89.

[0040] In use, the first drive motor 89 drives the second transmission shaft 86 to rotate. Then, the power is transmitted to the first transmission shaft 82 through the meshing transmission between the active bevel gear 87 and the driven bevel gear 88, thereby realizing the synchronous and unidirectional rotation of the spiral augers 83 on both sides. This ensures that the material dropping rate of the material tanks 6 on both sides is consistent, so that the raw materials fall symmetrically and evenly, further improving the premixing uniformity of the materials. Moreover, the gear transmission structure is stable and not prone to jamming or slippage.

[0041] Specifically, an inspection cover 810 is provided at the opening on one side of the quadrilateral frame 85, and the inspection cover 810 is connected to the quadrilateral frame 85 by bolts.

[0042] When wear or jamming occurs in the bevel gears, drive shafts and other transmission components inside the quadrilateral frame 85 during use, the staff can remove the bolts and take off the inspection cover 810 to facilitate the inspection, replacement and lubrication of the internal transmission components.

[0043] Working principle: First, the staff moves the equipment to the processing area, then puts the raw materials required for processing into the hopper 12. Next, the anti-blocking component 13 generates vibration to break up the accumulation of raw materials, thereby preventing the raw materials from blocking the discharge position of the hopper 12. The raw materials fall smoothly into the mounting shell 7 and are diverted to the material tanks 6 on both sides. Then, the feeding component 8 drives the spiral auger 83 to rotate at a constant speed, thereby smoothly conveying the raw materials in the material tank 6. The raw materials are evenly sprinkled into the premixing chamber 10 through the equally spaced discharge ports 84, thus expanding the raw material discharge area, avoiding the problem of concentrated accumulation of raw materials, and improving the premixing uniformity. After the raw materials enter the premixing chamber 10, the stirring component 11 stirs and agitates the various raw materials, thereby achieving the initial mixing of raw materials and completing the basic operation of material premixing processing.
