Description

Technical Field

[0001] The invention relates to the technical field of material feeding and mixing, in particular to a vacuum feeding integrated mixer and a mixing method. Background Art

[0002] The vacuum mixer is a highly integrated device that combines the functions of vacuum conveying and material mixing, and is widely used in the pharmaceutical, food, chemical and other industries. This equipment is mainly designed to handle powdered or granular materials, ensuring that the materials are conveyed and mixed in a dust-free, closed environment to achieve the purpose of improving production efficiency, ensuring product quality and complying with GMP (Good Manufacturing Practice) standards.

[0003] At present, in the prior art, vacuum feeding mixers are usually composed of a vacuum pump, a suction device, a conveying pipeline, a filter, a discharge door, and a mixing container. When working, the vacuum pump generates negative pressure, so that the material is sucked into the mixing container through the pipeline under the action of vacuum. In the mixing container, the material is fully mixed under controlled conditions and then discharged through the discharge door. The whole process is completed in a closed system, effectively avoiding external contamination.

[0004] However, when the discharge end of the vacuum feeder is connected to the feed end of the mixing container, they are usually connected manually to form a complete sealing structure. After the feeding is completed, the feeder is manually disassembled to separate the mixing container, which increases the workload, easily wastes time, increases the difficulty of work, and reduces work efficiency.

[0021] Reference Figure 1-Figure 4The feeding mechanism 200 includes a lifting component 220 and a vacuum feeder 210, and a feeding pipe 211 is connected to the vacuum feeder 210 by bolts. The mixing mechanism 300 includes a mixing and stirring chamber 310, a rotating component 320, a clamping component 330 and a docking component 340. A discharge port 311 is provided on the side wall of the mixing and stirring chamber 310. A second drive motor 400 is provided at the lower end of the mixing and stirring chamber 310. An auger 500 is rotatably connected inside the mixing and stirring chamber 310, and an output end of the second drive motor 400 is coaxially connected to the auger 500. The rotating assembly 320 includes a first driving motor 321, a motor support frame 322 and a connecting plate 323. The motor support frame 322 is welded or connected to the bracket 100 by bolts. The first driving motor 321 is connected to the motor support frame 322 by bolts. The connecting plate 323 is drivingly connected to the output end of the first driving motor 321. The mixing and stirring chamber 310 is fixed to the connecting plate 323 by a clamping assembly 330. The clamping assembly 330 includes a first clamping rod 331, a second clamping rod 332, a rotating shaft 333, and a locking bolt 334. The first clamping rod 331 is connected to the second clamping rod 332. The first through hole is formed at one end of the first clamping rod 31 and the second clamping rod 332, the second through hole is formed on the connecting plate 323, the rotating shaft 333 is penetrated in the first through hole and the second through hole, the first clamping rod 331 and the second clamping rod 332 are welded with a locking plate at the other end, the locking plate is provided with a threaded hole, and the locking bolt 334 is penetrated in the threaded hole; the docking assembly 340 includes a fixing ring 341, a plurality of blocking blocks 342, a sliding bar 343, a guide column 344 and a spring 345, the fixing ring 341 is connected to the feed pipe 312 away from the mixing and stirring bin 31 by bolts 0, a placement cavity is provided on the fixed ring 341, the slide bar 343 is arranged in the placement cavity, a slide groove is provided on the blocking block 342, the blocking block 342 is slidably connected in the placement cavity through the slide bar 343, a plurality of sliding holes are provided on the outer circumferential surface of the fixed ring 341, one end of the guide column 344 is fixedly connected to the blocking block 342, the other end of the guide column 344 is slidably connected in the sliding hole, the spring 345 is sleeved on the sliding column, one end of the spring 345 abuts against the blocking block 342, and the other end of the spring 345 abuts against the fixed ring 341.

[0022] When mixing and stirring the materials, the mixing and stirring bin 310 is placed between the first clamping rod 331 and the second clamping rod 332 by opening the first clamping rod 331 and the second clamping rod 332, and then the first clamping rod 331 and the second clamping rod 332 are rotated to clamp the mixing and stirring bin 310, and the first clamping rod 331 and the second clamping rod 332 are fixed by fixing bolts, so that the mixing and stirring bin 310 is stably connected to the rotating component 320. When the mixing and stirring bin 310 is fixed, the first driving motor 321 is started to drive the mixing and stirring bin 310 to rotate, which actually makes the mixing clamping bin rotate slightly and adjusts the mixing and stirring bin 310 to a vertical state. After that, the lifting component 220 drives the vacuum loader 210 to move downward, and the discharge pipe 211 first contacts the blocking block. At this time, the blocking block shrinks under the extrusion of the discharge pipe 211. The vacuum loader 210 transports the material to the mixing bin 310 through its own negative pressure. When the material transportation is completed, the lifting assembly 220 drives the vacuum loader 210 to move upward. When the lower feed pipe 211 is separated from the feed pipe 312, each blocking block moves toward the center of the circle under the action of the spring 345 (here, each blocking block is equipped with a guide column 344 and a spring 345, so that each blocking block, guide column 344, and spring 345 form a blocking module), so that multiple blocking blocks 342 form a circle to block the feed pipe 312, and then start the first drive motor 321 and the second drive motor 400 to make the mixing bin 310 rotate, and the auger 500 in the mixing bin 310 mixes and stirs the materials.

[0023] During feeding and mixing, the feeding and mixing are carried out simultaneously and sequentially through the docking assembly 340, thereby saving the connection time between the vacuum feeder 210 and the mixing and stirring bin 310, thereby improving the feeding and mixing efficiency; during the opening and closing of the blocking block, the spring 345 provides the power for the movement of the blocking block, and the guide column 344 and the slide bar 343 ensure that the blocking block slides along a specific track, so that the sealing of the blocking block can be improved when it shrinks into a circle. After the blocking block blocks the feed pipe 312, it can be determined whether the blocking block has completed the blocking operation by observing the length of the guide column 344 protruding outside the fixed ring 341, thereby reducing the probability of material leaking from the feed pipe 312 during the rotation of the mixing and stirring bin 310.

[0024] Reference Figure 1The lifting assembly 220 includes a lifting plate 221, a guide slide 222, a support frame 223 and a lifting cylinder 224. There are multiple guide slides 222, and the guide slides 222 are arranged on the bracket 100. The lifting plate 221 is slidably connected to the guide slides 222. The lifting cylinder 224 is arranged on the bracket 100. The output end of the lifting cylinder 224 is transmission-connected to the lifting plate 221. The support frame 223 is arranged on the lifting plate 221, and the vacuum loader 210 is arranged on one end of the support frame 223 away from the lifting plate 221.

[0025] When driving the vacuum loader 210 to rise and fall, the lifting cylinder 224 drives the lifting plate 221 to move upward or downward, thereby driving the support frame 223 to move upward or downward, thereby driving the vacuum loader 210 to move upward or downward. Due to the setting of the guide slide column 222, the vacuum loader 210 can move along the axial direction of the guide slide column 222 when moving up and down, thereby reducing the probability of the vacuum loader 210 being offset, thereby improving the accuracy of the docking between the discharge pipe 211 and the feed pipe 312.

[0026] The implementation principle of a mixed spraying device in the embodiment of the present application is: When mixing and stirring the materials, the mixing and stirring bin 310 is placed between the first clamping rod 331 and the second clamping rod 332 by opening the first clamping rod 331 and the second clamping rod 332, and then the first clamping rod 331 and the second clamping rod 332 are rotated to clamp the mixing and stirring bin 310, and the first clamping rod 331 and the second clamping rod 332 are fixed by fixing bolts, so that the mixing and stirring bin 310 is stably connected to the rotating component 320. When the mixing and stirring bin 310 is fixed, the first driving motor 321 is started to drive the mixing and stirring bin 310 to rotate, which actually makes the mixing clamping bin rotate slightly and adjusts the mixing and stirring bin 310 to a vertical state. After that, the lifting component 220 drives the vacuum loader 210 to move downward, and the discharge pipe 211 first contacts the blocking block. At this time, the blocking block shrinks under the extrusion of the discharge pipe 211. The vacuum loader 210 transports the material to the mixing bin 310 through its own negative pressure. When the material transportation is completed, the lifting assembly 220 drives the vacuum loader 210 to move upward. When the lower feed pipe 211 is separated from the feed pipe 312, each blocking block moves toward the center of the circle under the action of the spring 345 (here, each blocking block is equipped with a guide column 344 and a spring 345, so that each blocking block, guide column 344, and spring 345 form a blocking module), so that multiple blocking blocks 342 form a circle to block the feed pipe 312, and then start the first drive motor 321 and the second drive motor 400 to make the mixing bin 310 rotate, and the auger 500 in the mixing bin 310 mixes and stirs the materials.

[0027] Embodiment 2: The present invention provides a material mixing method, which comprises the following steps: S1: Fix the mixing and stirring chamber 310 on the rotating assembly 320 through the clamping assembly 330; S2: Start the first driving motor 321 to drive the mixing and stirring chamber 310 to rotate, so that the mixing and stirring chamber 310 is in a vertical state with the feeding pipe 312 at the top, and the feeding pipe 312 is aligned with the feeding pipe 211 of the vacuum loader 210; S3: Start the lifting cylinder 224 to move the vacuum feeder 210 downward. The feed pipe 211 applies pressure to the blocking block during the downward movement, so that the blocking block squeezes the spring 345 and moves in the direction of the spring 345. Then, the feed pipe 211 penetrates into the mixing and stirring chamber 310. S4: Start the vacuum feeder 210 to transport the material to the mixing and stirring chamber 310. When the material transportation is completed, the lifting cylinder 224 drives the vacuum feeder 210 to move upward. At this time, the blocking block 342 moves toward each other under the thrust of the spring 345 and blocks the feed pipe 312. S5: Start the second drive motor 400 and the first drive motor 321 , the first drive motor 321 drives the mixing and stirring bin 310 to rotate, and the second drive motor 400 drives the auger 500 to rotate, so as to achieve uniform mixing of the materials inside the mixing and stirring bin 310 .

[0028] The above are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
