Description

Technical Field

[0001] This utility model relates to the field of balancing mechanism technology, specifically to a quick rack changing balancing mechanism for a centrifuge used for fruit and vegetable extraction. Background Technology

[0002] Centrifuges, as key equipment in fruit and vegetable extraction and processing, work by using centrifugal force generated at high speed to separate juice from solid residue. However, traditional centrifuges often neglect dynamic balance and support stability in their structural design, leading to vibration, noise, and even mechanical failures during operation, severely impacting production efficiency and equipment lifespan.

[0003] Early centrifuges mostly used a fixed filter basket structure, lacking an automatic balancing mechanism. During high-speed rotation, uneven material distribution would directly disrupt the rotor's dynamic balance, causing severe vibration. Furthermore, the rotor structure of traditional centrifuges was relatively simple, relying solely on initial static balance calibration, which could not adapt to dynamic imbalances caused by material changes during operation. Utility Model Content

[0004] The present invention aims to solve the problems mentioned in the background art by providing a quick rack changing and balancing mechanism for a centrifuge used for fruit and vegetable extraction.

[0020] Example The quick rack-changing balancing mechanism for a centrifuge used for fruit and vegetable extraction provided in this embodiment, such as... Figures 1-7As shown, it includes: a lifting ring 5, which is sleeved on the outside of the centrifuge filter basket 1 and can move up and down; a support structure 6 is provided on the outside of the centrifuge filter basket 1, which plays a supporting and balancing role, preventing the centrifuge filter basket 1 from tilting to one side due to uneven distribution of internal materials; the support structure 6 includes a lifting column 66; a quick-change base 8 is detachably connected to the lower side of the centrifuge filter basket 1; the quick-change base 8 has a through hole for the lifting column 66 to pass through; the lifting column 66 is inserted into the through hole; two springs 68 are sleeved on the lifting column 66, which are respectively set at the upper and lower parts of the quick-change base 8; the springs 68 buffer the lifting column 66 as it moves up and down; a damping rod is installed between the quick-change base 8 and the drive connecting piece 9, which plays a role in shock absorption and energy absorption.

[0021] A limit plate 67 is welded to the lower part of the lifting column 66 to prevent the lower spring 68 from coming out. The upper end of the lifting column 66 is connected to a sleeve 65 by a thread. The sleeve 65 has a large diameter to prevent the upper spring 68 from coming out. A diagonal rod 62 is welded to the sleeve 65.

[0022] A hollow plastic block 63 is fixedly connected to the inclined rod 62. The hollow plastic block 63 supports the hopper 13, and its hollow structure provides a buffering effect. A rectangular rod 61 is rotatably connected to the upper part of the inclined rod 62. When installing the centrifuge filter basket 1, the rectangular rod 61 can be rotated outward for easy installation. The centrifuge filter basket 1 is provided with a guide groove 12, and one end of the rectangular rod 61 is located inside the guide groove 12. The hollow plastic block 63 is provided with a stepped portion 64, which can better buffer the vibration of the hopper 13.

[0023] The lower part of the quick-change base 8 is fixedly connected to a drive connecting piece 9, and the lower part of the drive connecting piece 9 is fixedly connected to a rotating plate 10. The rotating plate 10 has a keyway for connecting the output structure of the drive motor.

[0024] The upper part of the centrifuge filter basket 1 is fixedly connected to a flange 2, and the lower part of the flange 2 is fixedly connected to a guide rod 4. A guide hole is opened on the lifting ring 5. Several magnetic plates 7 are fixedly connected to the outside of the centrifuge filter basket 1. The lifting ring 5 serves to limit the rectangular rod 61. An iron block is provided inside the lifting ring 5, which can magnetically attract the magnetic plates 7 after installation.

[0025] The lifting ring 5 has a first groove 51, which is used to limit the rectangular rod 61. The drive connecting piece 9 has a mounting hole.

[0026] The centrifuge filter basket 1 has a drain hole 3 and a bucket 13 at the bottom. The centrifuge filter basket 1 can extract juice from fruits and vegetables during rotation.

[0027] An arc-shaped connecting groove 14 is provided on the bottom surface of the bucket 13. A connecting column 11 is fixedly connected to the quick-change base 8. A circular plate is fixedly connected to the top of the connecting column 11. The bucket 13 can be rotated and locked onto the connecting column 11 through the arc-shaped connecting groove 14. The circular plate prevents it from falling out.

[0028] In summary, the quick-change balancing mechanism for the centrifuge used for fruit and vegetable extraction provided in this embodiment has the following advantages: When installing the centrifuge filter basket 1, first rotate the rectangular rod 61 outward, then align and rotate the arc-shaped connecting groove 14 on the bottom surface of the bucket 13 onto the connecting post 11 of the quick-change base 8 to achieve initial positioning and connection. Next, reset the rectangular rod 61 so that one end is embedded in the guide groove 12 on the centrifuge filter basket 1. At this time, the lifting ring 5 moves down along the guide rod 4, and the first groove 51 on it limits the rectangular rod 61. At the same time, the iron block inside the lifting ring 5 is magnetically attracted to the magnet plate 7 on the outside of the centrifuge filter basket 1, thereby locking the entire filter basket assembly.

[0029] During operation, the output structure of the drive motor drives the rotating plate 10 to rotate via the keyway, which in turn drives the quick-change base 8 and the centrifuge filter basket 1 to rotate at high speed via the drive connecting piece 9 to extract fruit and vegetable juice. The juice is discharged through the drain hole 3. At this time, if uneven distribution of internal materials causes the centrifuge filter basket 1 to tilt, the support structure 6 will play a balancing and buffering role: the vibration of the bucket 13 will be transmitted to the stepped part 64 of the hollow plastic block 63, whose hollow structure acts as a buffer; the vibration is further transmitted to the lifting column 66 through the inclined rod 62 and the sleeve 65. The two springs 68 sleeved on the lifting column 66 and the damping rod installed between the quick-change base 8 and the drive connecting piece 9 work together to absorb vibration energy and provide buffering. The limit plate 67 and the sleeve 65 prevent the lower and upper springs 68 from coming out, respectively. The entire system effectively suppresses vibration and ensures smooth operation through the above-mentioned multi-level buffering and adaptive adjustment mechanism.

[0030] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
