Description

Technical Field

[0001] This utility model relates to the field of plastic product processing technology, and more specifically, it relates to a plastic product processing granule mixer. Background Art

[0002] In the plastic product processing industry, the mixer is one of the key pieces of equipment, and its performance directly affects the quality of the products and the production efficiency. However, the existing mixer design still has some significant limitations and shortcomings.

[0003] First, existing mixers generally use a single mixing rack design for mixing. This single-structure design has obvious drawbacks. Due to the limited coverage of the mixing rack, it is difficult to fully stir the entire mixing space in a short time, resulting in uneven mixing. This unevenness may lead to unstable quality of the final product, affecting the physical properties and appearance of plastic products. In addition, the single mixing rack design also limits the mixing efficiency, requiring a longer time to achieve the ideal mixing effect. This not only reduces production efficiency but may also increase energy consumption and production costs. In large-scale production, this inefficiency problem will be further amplified, potentially leading to a decrease in the efficiency of the entire production line.

[0004] Secondly, to address the low efficiency of single mixing racks, some improved designs have adopted rotary mixing tanks. While this design does improve mixing efficiency and facilitates unloading, it introduces new problems, particularly during loading and unloading. Rotary mixing tanks are typically equipped with sealing caps to prevent material leakage and the entry of external impurities. However, the current design for installing and removing these caps is not user-friendly and often requires specialized tools. This increases operational complexity and time costs, necessitating additional training for operators to familiarize themselves with these tools. It also increases the burden of tool management and maintenance. In production environments where material changes or equipment cleaning are frequent, this cumbersome process significantly reduces production efficiency. More importantly, the complex disassembly and assembly process may increase the risk of operational errors, potentially affecting the equipment's sealing and safety.

[0005] Finally, while some devices have achieved rapid disassembly and assembly of the sealing cap by introducing new mechanisms, these designs often suffer from simple structures and imperfect mechanisms. Such structural deficiencies may lead to several hidden dangers. First, simple rapid disassembly and assembly structures may not be able to effectively cope with the continuous vibration and centrifugal force generated by the high-speed rotation of the mixing tank. Long-term vibration and stress may cause the fixing mechanism to gradually loosen, and in extreme cases, it may even cause the sealing cap to fall off unexpectedly. This will not only interrupt the mixing process, but may also cause material waste and equipment damage. Second, insufficient structural stability may affect the sealing performance of the sealing cap, leading to leakage of small particles or dust. This will not only affect the accuracy of mixing, but may also pollute the working environment and even endanger the health of operators. Utility Model Content

The limiting mechanism includes a connecting block 10, a spring 11, a mating sleeve 12, a mating rod 13, an adapter groove 14, an adapter hole 15, a return block 16, an adapter 17, and a mating plate 18. The connecting block 10 is fixedly connected to the outside of the fixed sleeve 6. The two ends of the spring 11 are respectively connected to the connecting block 10 and the return block 16. The mating sleeve 12 is rotatably sleeved on the outside of the fixed sleeve 6. The mating rod 13 is connected to one side of the mating sleeve 12. The adapter groove 14 is opened on the adapter 17. The adapter hole 15 is opened at one end of the adapter groove 14. The return block 16 is fixedly connected to one side of the adapter 17. The adapter 17 is rotatably sleeved on the outside of the fixed sleeve 6. The mating plate 18 is fixedly set on the outside of the mating rod 13.

[0035] The self-locking mechanism includes a self-locking frame 19, a self-locking groove 20, and a return spring 21. The self-locking frame 19 is movably installed in the guide groove 9, the self-locking groove 20 is opened on the outside of the fixed rod 8, and the return spring 21 is connected to the inside of the self-locking frame 19.

[0036] A groove 22 is provided on the outer side of the fixing rod 8, and a slide rail 23 is fixed on the inner wall of the fixing sleeve 6. The slide rail 23 is adapted to the groove 22.

[0037] A limiting rod 24 is slidably provided on the side wall of the guide sleeve 7, and a connecting spring 25 is connected to the outer wall of the guide sleeve 7. One end of the limiting rod 24 is connected to the outer wall of the guide sleeve 7 through the connecting spring 25. A limiting groove 26 is opened on the outer wall of the fixed sleeve 6, and the other end of the limiting rod 24 is inserted into the limiting groove 26.

[0038] A push spring 27 is sleeved on the outside of the mating rod 13. One end of the push spring 27 is connected to the mating sleeve 12, and the other end of the push spring 27 is in contact with the mating sleeve 17.

[0039] In this embodiment, when the sealing cap 5 needs to be removed, firstly, the adapter 17 is rotated. The adapter 17 will drive the adapter hole 15, the adapter groove 14, and the return block 16 to rotate. At the same time, the return block 16 will cooperate with the connecting block 10 to compress the spring 11. When the spring 11 is compressed to its limit, the adapter hole 15 is in a position concentric with the mating plate 18. Then, the mating sleeve 12 is pushed, causing the mating sleeve 12 to drive the mating plate 18 and the mating rod 13 to slide. At the same time, the mating sleeve 12 will cooperate with the adapter 17 to compress the push spring 27 sleeved on the outside of the mating rod 13. When the push spring 27 is compressed to its limit, the mating plate 18 just passes through the adapter hole 15 and moves to the other side of the adapter 17. At this time, the adapter 17 is released, and the return block 16 will... The adapter 17 is reset, which in turn causes the adapter groove 14 and adapter hole 15 to rotate and reset. Then, the mating rod 13 enters the adapter groove 14, and the mating sleeve 12 is restricted to one side of the adapter 17 through the mating of the mating rod 13 and the mating plate 18. At this time, the outer side of the limiting rod 24 loses the restriction of the mating sleeve 12. Then, the guide sleeve 7 is rotated, which causes the limiting rod 24 to rotate. Then, the side wall of the limiting groove 26 presses against one end of the limiting rod 24. Due to the rounded corner treatment at the edge of the limiting groove 26 and the rounded corner structure design at the end of the limiting rod 24, one end of the limiting rod 24 will slide out of the limiting groove 26, and the other end of the limiting rod 24 will cause the connecting spring 25 to be stretched. At the same time, the guide sleeve 7 will cause the guide groove 9 to rotate. Due to the variable diameter structure design of the guide groove 9, the return spring 21 will push the self-locking frame 19 to move, so that the outer side of the self-locking frame 19 is always in contact with the inner wall of the guide groove 9. Then, one end of the self-locking frame 19 will gradually disengage from the self-locking groove 20. Then, the fixing sleeve 6 can be pulled upward to remove the fixing sleeve 6. Then, the sealing cover 5 can be removed. After the material feeding operation is completed, the sealing cover 5 is replaced on the mixing tank 2, and the fixing rod 8 passes through the mounting hole opened on the sealing cover 5. Then, the fixing sleeve 6 is re-fitted onto the outside of the fixing rod 8, so that the sliding groove 22 opened on the outside of the fixing rod 8 corresponds to the position of the sliding rail 23 set on the inner side of the fixing sleeve 6. Then, the guide sleeve 7 is rotated in the opposite direction, so that the guide sleeve 7 guides the guide groove 9 to rotate and reset. Then, the guide groove 9 The inner wall pushes the self-locking frame 19 to move, causing it to press against the return spring 21. Simultaneously, one end of the self-locking frame 19 inserts into the self-locking groove 20. Then, the adapter 17 rotates again, causing the adapter groove 14 and adapter hole 15 to move. The adapter 17 also causes the return block 16 to press against the spring 11 again. When the adapter hole 15 and the mating plate 18 are concentric, the push spring 27 pushes the mating sleeve 12 to slide back to its original position. Then, the mating sleeve 12 drives the mating rod 13 and mating plate 18 to slide back to their original position. After the push spring 27 has fully returned to its original position, the adapter 17 is released. The spring 11 pushes the return block 16 back to its original position. Then, the adapter 17 drives the adapter hole 15 and adapter groove 14 to return to their original positions, no longer corresponding to the mating rod 13 and mating plate 18.Then, the mating rod 13 and the fitting 17 cooperate to limit the mating sleeve 12, preventing it from sliding. The inner wall of the mating sleeve 12 then further limits the outer end of the limiting rod 24, preventing it from moving. Finally, the limiting rod 24 and the limiting groove 26 cooperate to limit the guide sleeve 7, preventing it from rotating. This ensures the relative stability of the structure and reduces the possibility of accidental loosening or even detachment.

[0040] Please see Figures 1-3 As a further implementation of the overall equipment: a mixing rack 28 is movably provided inside the mixing tank 2, a mixing motor 29 is provided below the rotating frame 4, and a handle 30 is connected to the top of the sealing cover 5.

[0041] A connecting frame 31 is fixedly installed on the inner wall of the mixing tank 2.

[0042] A reducer 32 is installed below the rotating frame 4 and on one side of the base 1. The output end of the reducer 32 is connected to the bottom end of the mixing frame 28 and one end of the rotating frame 4, respectively. The input end of the reducer 32 located below the rotating frame 4 is connected to the output end of the mixing motor 29, and the input end of the reducer 32 located on one side of the base 1 is connected to the output end of the drive motor 3.

[0043] More specifically, when using this equipment, first ensure that the sealing cover 5 is at the top of the mixing tank 2, then remove the sealing cover 5 and use the handle 30 to remove it. Next, feed the required raw material particles into the mixing tank 2. Then, reinstall and fix the sealing cover 5 to the opening of the mixing tank 2. Then, first turn on the mixing motor 29. After being reduced in speed by the reducer 32, the output of the mixing motor 29 drives the mixing frame 28 to rotate, thus mixing the raw material particles inside the mixing tank 2. Simultaneously, the fixed connecting frame 31 further enhances the uniformity of the mixing. Then, turn on the drive motor 3 installed on one side of the base 1. After being reduced in speed by the reducer 32, the output of the drive motor 3 drives the rotating frame 4 inside the base 1. The mixing tank 2 and the sealing cover 5 are flipped up and down, and the rotating frame 4 will drive the mixing tank 2 and the sealing cover 5 to flip up and down. This allows the raw material particles inside the mixing tank 2 to be mixed horizontally and vertically at the same time. This not only improves the uniformity of the mixture but also improves the mixing efficiency. After mixing, the external collection device is placed inside the base 1, below the mixing tank 2. Then the mixing tank 2 is inverted so that the sealing cover 5 is facing down. Then the sealing cover 5 is removed, allowing the mixed raw material particles to enter the collection device below by gravity. Then the mixing tank 2 is rotated back to its original position, and the sealing cover 5 is reinstalled on the opening of the mixing tank 2. When mixing is required again, the above steps can be followed.

[0044] In summary, during the use or operation of the overall equipment: when it is necessary to remove the sealing cover 5, first rotate the adapter 17. The adapter 17 will drive the adapter hole 15, the adapter groove 14, and the return block 16 to rotate. At the same time, the return block 16 will cooperate with the connecting block 10 to compress the spring 11. When the spring 11 is compressed to its limit, the adapter hole 15 is in a concentric position with the mating plate 18. Then push the mating sleeve 12, so that the mating sleeve 12 drives the mating plate 18 and the mating rod 13 to slide. At the same time, the mating sleeve 12 will cooperate with the adapter 17 to compress the push spring 27 sleeved on the outside of the mating rod 13. When the push spring 27 is compressed to its limit, the mating plate 18 just passes through the adapter hole 15 and moves to the other side of the adapter 17. At this time, the adapter 17 is released. The return block 16 will cause the adapter 17 to reset, and the adapter 17 will cause the adapter groove 14 and the adapter hole 15 to rotate and reset. Then, the mating rod 13 will enter the adapter groove 14, and the mating sleeve 12 will be restricted to the side of the adapter 17 through the mating of the mating rod 13 and the mating plate 18. At this time, the outer side of the limiting rod 24 will lose the restriction of the mating sleeve 12. Then, the guide sleeve 7 will rotate, and the guide sleeve 7 will cause the limiting rod 24 to rotate. Then, the side wall of the limiting groove 26 will press against one end of the limiting rod 24. Due to the rounded corner treatment at the edge of the limiting groove 26 and the rounded corner structure design at the end of the limiting rod 24, one end of the limiting rod 24 will slide out of the limiting groove 26, and the other end of the limiting rod 24 will cause the connecting spring 25 to be stretched. At the same time, the guide sleeve 7 will drive the guide... As the guide groove 9 rotates, due to the variable diameter structure design of the guide groove 9, the return spring 21 will push the self-locking frame 19 to move, so that the outer side of the self-locking frame 19 is always in contact with the inner wall of the guide groove 9. Then, one end of the self-locking frame 19 will gradually disengage from the self-locking groove 20. Then, pull the fixing sleeve 6 upward to remove the fixing sleeve 6, and then remove the sealing cover 5. After the material feeding operation is completed, put the sealing cover 5 back on the mixing tank 2, and let the fixing rod 8 pass through the mounting hole opened on the sealing cover 5. Then, put the fixing sleeve 6 back on the outside of the fixing rod 8, so that the sliding groove 22 opened on the outside of the fixing rod 8 corresponds to the position of the sliding rail 23 set on the inside of the fixing sleeve 6. Then, rotate the guide sleeve 7 in the opposite direction, so that the guide sleeve 7 guides the guide groove 9 to rotate and reset. The self-locking frame 19 is pushed to move against the inner wall of the groove 9, causing it to press against the return spring 21. Simultaneously, one end of the self-locking frame 19 inserts into the self-locking groove 20. Then, the adapter 17 is rotated again, causing the adapter groove 14 and adapter hole 15 to move. The adapter 17 also causes the return block 16 to press against the spring 11 again. When the adapter hole 15 and the mating plate 18 are concentric, the push spring 27 pushes the mating sleeve 12 to slide back to its original position. Then, the mating sleeve 12 drives the mating rod 13 and mating plate 18 to slide back to their original position. After the push spring 27 has fully returned to its original position, the adapter 17 is released, and the spring 11 pushes the return block 16 back to its original position. Then, the adapter 17 drives the adapter hole 15 and adapter groove 14 to return to their original positions, no longer corresponding to the mating rod 13 and mating plate 18.Then, the mating rod 13 and the fitting 17 cooperate to limit the mating sleeve 12, preventing it from sliding. The inner wall of the mating sleeve 12 then further limits the outer end of the limiting rod 24, preventing it from moving. Finally, the limiting rod 24 and the limiting groove 26 cooperate to limit the guide sleeve 7, preventing it from rotating. This ensures the relative stability of the structure and reduces the possibility of accidental loosening or even detachment.

[0045] When using the equipment, first ensure that the sealing cover 5 is at the top of the mixing tank 2. Then remove the sealing cover 5 and use the handle 30 to remove it. Next, feed the required raw material particles into the mixing tank 2. Then, reinstall and fix the sealing cover 5 to the opening of the mixing tank 2. Then, first turn on the mixing motor 29. After being reduced in speed by the reducer 32, the output of the mixing motor 29 drives the mixing frame 28 to rotate, thus mixing the raw material particles inside the mixing tank 2. Simultaneously, the fixed connecting frame 31 further enhances the uniformity of the mixing. Then, turn on the drive motor 3 installed on one side of the base 1. After being reduced in speed by the reducer 32, the output of the drive motor 3 drives the rotating frame 4 to rotate inside the base 1. The mixing tank 2 and the sealing cover 5 are flipped upside down by the rotating frame 4. This causes the raw material particles inside the mixing tank 2 to be mixed vertically while being mixed horizontally. This not only improves the uniformity of the mixture but also increases the mixing efficiency. After mixing, the external collection device is placed inside the base 1, below the mixing tank 2. Then, the mixing tank 2 is inverted so that the sealing cover 5 is facing down. The sealing cover 5 is then removed, allowing the mixed raw material particles to enter the collection device below due to gravity. The mixing tank 2 is then rotated back to its original position, and the sealing cover 5 is then reinstalled at the opening of the mixing tank 2. When mixing is required again, the above steps can be followed.

For all the fixed connections mentioned above, welding is preferred.
