Description

Technical Field

[0001] This utility model relates to the technical field of rust-proof vacuum pumice machine, and more specifically, it relates to a rust-proof vacuum pumice machine. Background Technology

[0002] In existing technologies, vacuum clay mixing machines are key equipment in ceramic production and artistic creation. Their design and function directly affect the quality of clay, operational efficiency, and the lifespan of the equipment. However, existing clay mixing machines have many problems that urgently need to be solved, especially the defects in equipment structure and maintenance. Traditional clay mixing silos are usually produced using an integrated casting process. Although this integrated design simplifies the production process and reduces manufacturing costs in the initial manufacturing process, it brings many inconveniences in long-term use. Because the clay mixing silo is tightly connected to other components, forming an inseparable whole, operators cannot easily disassemble the clay mixing silo. This design limitation leads to huge challenges when the equipment needs cleaning and maintenance. Especially after long-term use, clay forms stubborn residues on the inner wall of the clay mixing silo. If it cannot be thoroughly cleaned, it will not only affect the purity and uniformity of subsequent clay, but also accelerate the corrosion and aging of the equipment. More seriously, these residues may breed bacteria and mold, posing a potential threat to product quality and the health of operators. Due to the inability to effectively clean the clay mixing silo, the lifespan of the equipment is significantly shortened, increasing the equipment replacement costs and maintenance burden for enterprises.

[0003] Secondly, some equipment manufacturers have recognized the above problems and attempted to solve the difficulty of cleaning the mud-refining silo by improving the design. Although these improved models have initially achieved convenient installation and disassembly of the mud-refining silo through the cooperation of some simple components, the design of these connection structures is too simple and crude, resulting in low overall stability. During equipment operation, these simple connection devices are easily affected by strong mechanical vibration and centrifugal force, causing the fixing structure to loosen or even fall off. In addition, in daily operation, external factors such as improper operation by operators and frequent movement of equipment may further aggravate the loosening of these connection parts, eventually leading to accidental loosening or even complete unlocking. Such connection failure will not only cause the mud-refining silo to be unstable, affecting the normal operation of the equipment and the quality of the mud, but in severe cases, it may even cause the mud-refining silo to suddenly fall off during operation, causing not only material waste and equipment damage, but also posing a threat to the personal safety of operators. These potential safety hazards and stability problems seriously restrict the working efficiency and application range of the mud-refining machine. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] In view of the problems existing in the prior art, this utility model provides a rust-proof vacuum pumice machine to solve the technical problems mentioned in the background art.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a rust-proof vacuum pumice machine, comprising a base, a lower shell detachably mounted on the base, an upper shell detachably mounted on the lower shell, a fixing plate fixedly connected to the outer sides of both the upper and lower shells, a locking sleeve mounted on the fixing plate, a locking rod detachably mounted inside the locking sleeve, a locking sleeve mounted outside the locking sleeve, the locking sleeve being threadedly disposed outside the locking sleeve, a release sleeve rotatably mounted outside the locking sleeve, and a locking frame fixedly mounted on one side of the release sleeve. The release sleeve has a variable-diameter release groove on its inner side, the locking sleeve has a locking groove on its outer wall, the locking frame has a sliding locking rod, the release groove has a sliding release plate, the release plate has a locking block connected to one side, the locking rod has a storage groove on its outer side, the storage groove has a rotating shaft, the storage groove has a locking plate, the locking block abuts against one end of the locking plate, the locking plate is rotatably installed in the storage groove via the rotating shaft, the locking plate has a tension spring connected to one side, and the other end of the tension spring is connected to the inner wall of the storage groove.

[0008] The present invention is further configured such that a mud-dividing plate is detachably provided on the inner side of the lower shell and the upper shell, a mud-refining frame is rotatably provided in the upper shell and the lower shell, a feed hopper is detachably connected to the top of the upper shell, a vacuum chamber is provided on one side of the feed hopper, and the vacuum chamber is installed above the upper shell. This modular structure design significantly improves the functionality and ease of maintenance of the equipment. The mud-dividing plate ensures the uniform distribution of mud during the refining process. The rotatably provided mud-refining frame, together with the upper and lower shells, forms a complete mud-refining space, realizing the full mixing and stirring of the mud. The vacuum chamber provided on one side of the feed hopper creates a negative pressure environment by extracting air from the system, effectively removing air bubbles in the mud and improving the quality of the finished product.

[0009] The present invention is further configured such that a drive assembly is detachably mounted on the base, and the output end of the drive assembly is connected to one end of the mud-pumping frame. This power transmission structure design improves the operational reliability of the equipment.

[0010] The present invention is further provided with multiple anti-slip strips connected to the outer sides of both the release sleeve and the locking sleeve. This user-friendly operation design significantly improves the safety and convenience of equipment operation. The anti-slip strips increase the friction between the fingers and the operating parts, preventing operational errors caused by slipping or wetness during rotation, especially in muddy environments where hands may be covered in mud. The anti-slip strips ensure that the operator can accurately control the rotation angle and force of the release sleeve and the locking sleeve even under less than ideal conditions. At the same time, the raised structure of the anti-slip strips also provides clear tactile feedback.

[0011] The present invention is further configured such that a guide groove is provided on the outer side of the locking rod, and a guide rail is fixedly provided on the inner side of the locking sleeve. The guide groove and the guide rail are adapted to each other. This precise guiding structure design greatly improves the accuracy and stability of component installation. The adaptation design of the guide groove and the guide rail forms a strict positioning constraint, ensuring that the locking rod and the locking sleeve can be precisely connected along the predetermined trajectory during installation, preventing skewness and misalignment.

[0012] The present invention is further configured such that a locking spring is movably sleeved on the outside of the locking rod, a locking plate is connected to one end of the locking rod, and the two ends of the locking spring are respectively connected to the locking plate and the locking frame. This elastic locking structure design realizes the automatic reset of the locking mechanism.

[0013] The present invention is further configured such that one end of the locking rod and the edge of the inner wall of the locking groove are both designed with rounded corners. This detailed optimization design greatly improves the smoothness of operation and service life of the locking mechanism. The rounded corners eliminate sharp edges, allowing the locking rod to slide smoothly when entering and exiting the locking groove, reducing jamming and wear, lowering operating resistance, and improving operating comfort.

[0014] The present invention is further configured such that the top of the inner part of the locking sleeve adopts a sloping structure design. The sloping structure forms a natural guide surface during the docking process between the locking sleeve and the locking rod, which can guide the locking plate to automatically adjust its position and achieve precise docking.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a rust-proof vacuum pumice machine, which has the following beneficial effects:

[0017] 1. By designing a detachable upper and lower shell structure, along with an innovative connection mechanism consisting of a fixing plate, locking sleeve, locking rod, and release sleeve, the problem of the inability to separate the integral casting of the mud refining bin in existing technologies is completely solved. This design allows operators to easily separate the upper and lower shells without the need for tools, facilitating a thorough cleaning of the inside of the mud refining bin. This effectively removes stubborn residues from the inner wall, preventing the growth of bacteria and mold. During the cleaning process, internal components such as the mud separating plate and mud refining rack can also be fully exposed for thorough cleaning. By ensuring the cleanliness and hygiene of the equipment's interior, not only is the purity and uniformity of the subsequent mud material improved, but the corrosion and aging rate of the equipment is also effectively slowed down, extending the equipment's service life and reducing the company's equipment replacement costs and maintenance burden. At the same time, it also ensures product quality and the health and safety of operators. The detachable design makes maintenance simple and efficient, greatly enhancing the equipment's practicality and economic value.

[0018] 2. Through a meticulously designed locking mechanism, including the locking sleeve limiting the locking plate and locking rod, and the interlocking structure between the locking rod and the locking groove, the problem of low stability in existing simple connection devices is successfully solved. This forms multiple locking protections, preventing accidental loosening caused by mechanical vibration and centrifugal force during equipment operation. The anti-slip strip on the outside of the release sleeve enhances the friction and control precision of operation, while the rounded corner design of the locking rod and the edge of the locking groove ensures smooth locking and unlocking. The sloping structure at the top of the inner end of the locking sleeve allows the locking plate to automatically adjust its position, forming a reliable locking relationship. This multi-safety locking system can maintain the stability of the connection even when the equipment is running at high speed or subjected to external interference, effectively preventing the safety hazard of the mud-making bin suddenly falling off during operation, avoiding material waste and equipment damage, and ensuring the personal safety of operators. At the same time, the design of the entire locking system takes into account both ease of installation and robustness, making the disassembly and assembly process of the equipment simple and efficient, significantly improving the working efficiency and application range of the mud-making machine.

[0028] Please see Figures 1-5 A rust-proof vacuum pumice machine includes a base 1, a lower shell 2 detachably mounted on the base 1, and an upper shell 3 detachably mounted on the lower shell 2. A fixing plate 4 is fixedly connected to the outer sides of both the upper shell 3 and the lower shell 2. A locking sleeve 5 is mounted on the fixing plate 4. A locking rod 6 is detachably mounted inside the locking sleeve 5. A locking sleeve 7 is mounted outside the locking sleeve 5, and the locking sleeve 7 is threadedly mounted on the outside of the locking sleeve 5. A release sleeve 8 is rotatably mounted on the outside of the locking sleeve 5. A locking frame 9 is fixedly mounted on one side of the release sleeve 8. A release groove 10 with a variable diameter is opened on the inner side of the release sleeve 8. The outer wall of the sleeve 5 is provided with a locking groove 11, the locking frame 9 is provided with a locking rod 12, the release groove 10 is provided with a release plate 13, the release plate 13 is connected to a locking block 14 on one side, the locking rod 6 is provided with a storage groove 15 on the outside, the storage groove 15 is provided with a rotating shaft 16, the storage groove 15 is provided with a locking plate 17, the locking block 14 abuts against one end of the locking plate 17, the locking plate 17 is rotatably installed in the storage groove 15 through the rotating shaft 16, the locking plate 17 is connected to a tension spring 18 on one side, and the other end of the tension spring 18 is connected to the inner wall of the storage groove 15.

[0029] The inner sides of the lower shell 2 and the upper shell 3 are detachably equipped with mud-dividing plates 19. The upper shell 3 and the lower shell 2 are rotatably equipped with mud-powdering racks 20. The top of the upper shell 3 is detachably connected to a feed hopper 21. A vacuum chamber 22 is provided on one side of the feed hopper 21. The vacuum chamber 22 is installed above the upper shell 3.

[0030] A drive assembly 23 is detachably mounted on the base 1, and the output end of the drive assembly 23 is connected to one end of the mud-mixing frame 20.

[0031] In this embodiment, when the mud-making operation is required, the raw mud is first fed into the machine through the top feed hopper 21. The design of the feed hopper 21 allows the raw material to enter the upper shell 3 and begin to contact the mud-making frame 20. The drive assembly 23, as the power source of the entire system, is installed on the base 1 and connected to the mud-making frame 20. The mechanical energy generated by the motor drives the mud-making frame 20 to rotate within the upper and lower shells 2. The rotating mud-making frame 20 applies stirring and shearing forces to the mud, making it fully and evenly mixed. At the same time, the vacuum chamber 22 on one side of the upper shell 3 starts to work, extracting air from the system and creating a negative pressure environment inside the machine. This vacuum state can effectively remove air bubbles in the mud, prevent pores in the finished product, and improve the quality of the mud. The mud-dividing plate 19 is set inside the upper and lower shells 2 and plays a guiding and diversion role during the rotation of the mud-making frame 20, ensuring that the mud is evenly stressed. The fully-made mud is finally discharged from the outlet at one end of the equipment, completing the entire mud-making process.

[0032] Please see Figures 3-5 As a further implementation of the overall device: multiple anti-slip strips 24 are connected to the outer sides of both the release sleeve 8 and the locking sleeve 7.

[0033] The outer side of the locking rod 6 is provided with a guide groove 25, and the inner side of the locking sleeve 5 is fixed with a guide rail 26. The guide groove 25 is adapted to the guide rail 26.

[0034] A locking spring 27 is movably sleeved on the outside of the locking rod 12. A locking plate 28 is connected to one end of the locking rod 12. The two ends of the locking spring 27 are connected to the locking plate 28 and the locking frame 9, respectively.

[0035] Both the locking rod 12 and the inner edge of the locking groove 11 are designed with rounded corners.

[0036] The top of the inner part of the card sleeve 5 adopts a sloping structure design.

[0037] More specifically, when the upper shell 3 and lower shell 2 need to be disassembled for internal cleaning, firstly, the locking sleeve 7 is rotated forward. The locking sleeve 7 will move along the outer thread of the retaining sleeve 5, so that the inner wall of the retaining sleeve 5 gradually no longer limits the outer wall of the retaining plate 17. Then, the release sleeve 8 is rotated forward. The release sleeve 8 will then drive one side of the locking frame 9 to rotate forward, so that the locking frame 9 drives the locking rod 12, the locking plate 28 and the locking spring 27 to rotate forward. Then, the inner wall of the locking groove 11 presses against one end of the locking rod 12. Due to the rounded corner design of the inner wall edge of the locking groove 11 and one end of the locking rod 12, one end of the locking rod 12 will slide out of the locking groove 11, and the other end of the locking rod 12 will be stretched outward by the locking plate 28 and the locking spring 27. At the same time, the release sleeve 8 will drive the locking rod 12 to rotate outward. The release groove 10, which has a variable diameter on the inner side, rotates in the forward direction, causing the release plate 13 to slide the locking block 14 outward, so that the locking block 14 no longer abuts against the lower end of the locking plate 17. Then, the locking sleeve 5 and the locking rod 6 are pulled up and down respectively, causing the locking sleeve 5 to drive the inner guide rail 26 to gradually slide out of the guide groove 25, and the outer wall of the locking plate 17 is gradually no longer limited by the sloping inner wall at the top of the locking sleeve 5. Then, the tension spring 18 will gradually reset and pull the locking plate 17 to rotate along the rotating shaft 16, so that one end of the locking plate 17 rotates into the receiving groove 15, thus completely separating the locking sleeve 5 and the locking rod 6. Then, following the above steps, the other locking sleeves 5 and locking rods 6 are removed, and then the upper shell 3 is removed, thus achieving the separation of the locking sleeve 5 and the locking rod 6. Cleaning of the upper shell 3 and the inner shell (the parts between them) is performed. After cleaning, the upper shell 3 is reinstalled on top of the lower shell 2, ensuring that the pre-drilled mounting holes on the outer fixing plate 4 of the upper shell 3 and the outer fixing plate 4 of the lower shell 2 are concentric. Then, the locking rod 6 is passed through the mounting hole from the bottom, and the locking sleeve 5 is re-fitted onto the outside of the locking rod 6, allowing the inner guide rail 26 of the locking sleeve 5 to slide back into the guide groove 25. The sloping inner wall at the top of the locking sleeve 5 will then press against the upper outer wall of the locking plate 17 again, causing the upper end of the locking plate 17 to move inward. The locking plate 17 then rotates in the opposite direction along the rotating shaft 16, causing the lower inner wall of the locking plate 17 to stretch the tension spring 18. When the locking sleeve 5 is fully fitted onto the outside of the locking rod 6, the sleeve 8 is rotated in the opposite direction to release it. The release sleeve 8, through the locking frame 9, drives the locking plate 28, locking spring 27, and locking rod 12 to rotate in the opposite direction. Simultaneously, the release sleeve 8 drives the inner release groove 10 to rotate in the opposite direction, causing the release plate 13 to slide the locking block 14 inwards to reset, so that one side of the locking block 14 abuts against one end of the locking plate 17, forming an engagement. At this time, the locking frame 9 drives the locking rod 12 and other components to rotate and reset to the position corresponding to the original locking groove 11. Then, the locking spring 27 pulls the locking plate 28 to slide and reset, causing the locking plate 28 to drive the locking rod 12 to slide and reset into the original locking groove 11. Then, the locking sleeve 7 rotates in the opposite direction, causing the locking sleeve 7 to move and reset along the threads on the outer wall of the locking sleeve 5, thus limiting the inner wall of the locking sleeve 7 against the outer wall of the locking plate 28.This prevents the locking plate 28 and locking rod 12 from moving outwards. Then, the locking rod 12, in conjunction with the locking groove 11, limits the locking frame 9, preventing accidental rotation of the locking frame 9 and release sleeve 8. This avoids accidental loosening and unlocking, ensuring convenient and stable installation between the upper shell 3 and the lower shell 2.

[0038] In summary, during the use or operation of the overall equipment: When the mud-making operation is required, the raw mud is first fed into the machine through the top feed hopper 21. The design of the feed hopper 21 allows the raw material to enter the upper shell 3 and begin to contact the mud-making frame 20. The drive assembly 23, as the power source of the entire system, is installed on the base 1 and connected to the mud-making frame 20. The mechanical energy generated by the motor drives the mud-making frame 20 to rotate within the upper and lower shells 2. The rotating mud-making frame 20 applies stirring and shearing forces to the mud, making it fully and evenly mixed. At the same time, the vacuum chamber 22 on one side of the upper shell 3 starts to work, extracting air from the system and creating a negative pressure environment inside the machine. This vacuum state can effectively remove air bubbles in the mud, prevent porosity in the finished product, and improve the quality of the mud. The mud-dividing plate 19 is set inside the upper and lower shells 2 and plays a guiding and diversion role during the rotation of the mud-making frame 20, ensuring that the mud is evenly stressed. The fully processed mud is finally discharged from the outlet at one end of the equipment, completing the entire mud-making process.

[0039] When the upper shell 3 and lower shell 2 need to be disassembled for internal cleaning, first rotate the locking sleeve 7 clockwise. The locking sleeve 7 will move along the outer thread of the locking sleeve 5, so that the inner wall of the locking sleeve 5 gradually no longer limits the outer wall of the locking plate 17. Then rotate the release sleeve 8 clockwise. The release sleeve 8 will drive the locking frame 9 on one side to rotate clockwise, so that the locking frame 9 drives the locking rod 12, the locking plate 28 and the locking spring 27 to rotate clockwise. Then the inner wall of the locking groove 11 presses against one end of the locking rod 12. Due to the rounded corner design of the inner wall edge of the locking groove 11 and one end of the locking rod 12, one end of the locking rod 12 will slide out of the locking groove 11, and the other end of the locking rod 12 will be stretched outward by the locking plate 28 and the locking spring 27. At the same time, the release sleeve 8 will drive the inner side to change The radially opened release groove 10 is rotated in the forward direction, causing the release plate 13 to slide the locking block 14 outward, so that the locking block 14 no longer abuts against the lower end of the locking plate 17. Then, the locking sleeve 5 and the locking rod 6 are pulled up and down respectively, so that the locking sleeve 5 drives the inner guide rail 26 to gradually slide out of the guide groove 25, and the outer wall of the locking plate 17 is gradually no longer limited by the sloping inner wall at the top of the locking sleeve 5. Then, the tension spring 18 will gradually reset and pull the locking plate 17 to rotate along the rotating shaft 16, so that one end of the locking plate 17 rotates into the receiving groove 15, thus completely separating the locking sleeve 5 and the locking rod 6. Then, following the above steps, the other locking sleeves 5 and locking rods 6 are removed, and then the upper shell 3 is removed, thus realizing the removal of the upper shell. 3. Clean the components between the upper shell and the inner shell. After cleaning, reinstall the upper shell 3 on top of the lower shell 2, ensuring that the pre-drilled mounting holes on the outer fixing plate 4 of the upper shell 3 and the outer fixing plate 4 of the lower shell 2 are concentric. Then, pass the locking rod 6 through the mounting hole from the bottom, and then re-fit the locking sleeve 5 onto the outside of the locking rod 6, so that the inner guide rail 26 of the locking sleeve 5 slides back into the guide groove 25. Then, the sloping inner wall at the top of the locking sleeve 5 will press against the upper outer wall of the locking plate 17 again, causing the upper end of the locking plate 17 to move inward. Then, the locking plate 17 rotates in the opposite direction along the rotating shaft 16, causing the lower inner wall of the locking plate 17 to drive the tension spring 18 to stretch. When the locking sleeve 5 is fully fitted onto the outside of the locking rod 6, rotate in the opposite direction to release the sleeve 8. The release sleeve 8, through the locking frame 9, drives the locking plate 28, locking spring 27, and locking rod 12 to rotate in the opposite direction. Simultaneously, the release sleeve 8 drives the inner release groove 10 to rotate in the opposite direction, causing the release plate 13 to drive the locking block 14 to slide inward and reset, so that one side of the locking block 14 abuts against one end of the locking plate 17, forming an engagement relationship. At this time, the locking frame 9 drives the locking rod 12 and other components to rotate and reset to the position corresponding to the original locking groove 11. Then, the locking spring 27 pulls the locking plate 28 to slide and reset, causing the locking plate 28 to drive the locking rod 12 to slide and reset into the original locking groove 11. Then, the locking sleeve 7 rotates in the opposite direction, causing the locking sleeve 7 to move and reset along the threaded outer wall of the locking sleeve 5, so that the inner wall of the locking sleeve 7 limits the outer wall of the locking plate 28.This prevents the locking plate 28 and locking rod 12 from moving outwards. Then, the locking rod 12, in conjunction with the locking groove 11, limits the locking frame 9, preventing accidental rotation of the locking frame 9 and release sleeve 8. This avoids accidental loosening and unlocking, ensuring convenient and stable installation between the upper shell 3 and the lower shell 2.
