Description

Technical Field

[0001] This utility model relates to a mixing device for coating production, and in particular a highly flexible mixer for washable ceramic coatings. Background Technology

[0002] In the production of ceramic coatings, a mixer is needed to uniformly mix various raw materials. Existing mixers mainly consist of a mixing motor, a mixing shaft, and a mixing head mounted on the end of the shaft. The mixing head is typically fixed to the mixing shaft. However, in actual use, the addition of different raw materials in each mixing step results in varying mixing speeds and times, and different materials exert different resistances on the mixing head. Therefore, different shaped mixing heads are needed to mix different materials. However, the fixed mounting of the mixing head on the mixing shaft in existing mixers limits their ability to handle only one type of material, resulting in poor overall flexibility. Therefore, existing mixers lack flexibility in handling materials with diverse mixing requirements. Utility Model Content

[0003] The purpose of this invention is to provide a highly flexible mixer for washable ceramic coatings. This invention offers the advantage of high flexibility in use.

[0004] The technical solution of this utility model: A highly flexible, washable ceramic coating mixer, including a base, a mixing motor, and a mixing tank. A mixing main shaft is mounted on the mixing motor, and a first external thread section is provided on the outer side of the end of the mixing main shaft. A mixing secondary shaft is threadedly connected to the end of the mixing main shaft, and the end of the mixing secondary shaft has a mounting groove for connecting to the mixing main shaft. A first internal thread section that mates with the first external thread section is provided on the inner wall of the mounting groove. A second external thread section with a thread direction opposite to that of the first thread section is provided on the outer side of the mixing secondary shaft. An outer fixing sleeve is threadedly connected to the second external thread section, and a second internal thread section that mates with the second external thread section is provided on the inner wall of the outer fixing sleeve. A mixing head is mounted on the end of the mixing secondary shaft. Two symmetrically arranged lifting devices are mounted on the base. A lifting base for mounting the stirring motor is provided between the lifting devices. The stirring auxiliary shaft and the stirring main shaft are connected by a threaded connection, so that when it is necessary to change the style of the stirring head, only the stirring auxiliary shaft needs to be removed from the stirring main shaft to replace the stirring head. This allows one stirring motor to drive different stirring heads in multiple times, improving the flexibility of use. The external fixing sleeve not only fixes and protects the connection between the stirring main shaft and the stirring auxiliary shaft, ensuring the stability of the structure and extending its service life, but also increases the mutual reaction force during the rotation of the stirring main shaft driven by the stirring motor by the stirring auxiliary shaft, increasing the tightness of the connection between the stirring main shaft and the stirring auxiliary shaft during rotation, ensuring the stability of the structure.

[0005] In the aforementioned highly flexible washable ceramic coating mixer, the end of the mixing main shaft is provided with a positioning groove; the center of the bottom surface of the mounting groove is provided with a positioning component that cooperates with the positioning groove; by providing a positioning groove at the end of the mixing main shaft, and cooperating with the positioning component at the end of the mixing auxiliary shaft, the installation between the mixing main shaft and the mixing auxiliary shaft is positioned, which facilitates replacement and assembly, and also increases the connection area between the mixing main shaft and the mixing auxiliary shaft, ensuring the stability of the structure.

[0006] In the aforementioned highly flexible and washable ceramic coating mixer, a limiting ring is provided on the mixing sub-shaft, located directly below the second external thread section, and a first magnetic ring is provided on the top surface of the limiting ring; an auxiliary ring is provided on the mixing main shaft, located directly above the first external thread section, the distance between the auxiliary ring and the first external thread section being greater than the length of the outer fixing sleeve, and a first magnetic ring is also provided on the bottom surface of the auxiliary ring; a second magnetic ring is provided on both the upper and lower sides of the outer fixing sleeve, and the second magnetic ring cooperates with the first magnetic ring; the limiting ring can limit, support, and fix the outer fixing sleeve from below, further ensuring the stability of the structure; the first and second magnetic rings connect the auxiliary ring to the outer fixing sleeve, so that during the replacement of the mixing head, the outer fixing sleeve can be stably fixed on the auxiliary ring on the mixing main shaft, preventing the outer fixing sleeve from slipping off, further facilitating the replacement of the mixing head.

[0007] In the aforementioned highly flexible washable ceramic coating mixer, the lifting device includes a support seat vertically mounted on a base, and a ball screw is provided on the side of the support seat facing the mixing tank; a servo motor is connected to the end of the ball screw, and a sliding seat is slidably mounted on the ball screw, with the top surface of the sliding seat fixedly connected to the bottom surface of the lifting seat.

[0008] In the aforementioned highly flexible and washable ceramic coating mixer, the ball screw is equipped with support rails on both sides, and each support rail has limit blocks at both ends; the lifting seat has two symmetrically arranged through holes at both ends; the support rails are slidably disposed within the through holes; the support rails support and guide the movement of the lifting seat, ensuring structural stability; and the limit blocks at both ends of the support rails limit the movement at the upper and lower ends of the lifting seat's sliding path, preventing over-movement and ensuring operational stability.

[0009] In the aforementioned highly flexible and washable ceramic coating mixer, the outer surface of the outer fixing sleeve is provided with multiple annularly distributed anti-slip ridges; the anti-slip ridges can increase the friction between the outer fixing sleeve and the external force-applying object, which facilitates the rotation of the outer fixing sleeve and makes it convenient to use.

[0010] Compared with existing technologies, this invention improves the existing stirring device for ceramic coating production. By incorporating a main stirring shaft on the stirring motor and a secondary stirring shaft on the stirring head, the main and secondary stirring shafts are connected by a threaded connection. This allows for easy replacement of the stirring head simply by removing the secondary stirring shaft from the main stirring shaft. Unlike previous stirring devices where a single stirring motor could only drive a single stirring head, this invention enables a single motor to drive different stirring heads multiple times, improving operational flexibility. Furthermore, by providing an outer fixing sleeve at the connection point between the main and secondary stirring shafts, and threading the outer fixing sleeve to the secondary stirring shaft, with the threaded connection direction aligned with the secondary stirring shaft... The design is the opposite of the threaded connection of the main mixing shaft. The external fixing sleeve not only secures and protects the connection between the main mixing shaft and the auxiliary mixing shaft, preventing wear from the material during mixing and ensuring structural stability while extending service life, but also increases the mutual reaction force as the mixing motor drives the main mixing shaft. This enhances the tightness of the connection between the main and auxiliary mixing shafts during rotation, further ensuring structural stability. The lifting device and lifting seat allow the mixing motor, main mixing shaft, auxiliary mixing shaft, and mixing head to move up and down inside and outside the mixing tank, enabling the mixing head to be removed from the tank. This facilitates not only the replacement of mixing components but also the loading and unloading of materials into the mixing tank, making it convenient to use.

[0011] Furthermore, this invention also provides a positioning groove at the end of the main stirring shaft, which, in conjunction with a positioning component at the end of the auxiliary stirring shaft, positions the main stirring shaft and the auxiliary stirring shaft for installation. This facilitates replacement and assembly while increasing the connection area between the main stirring shaft and the auxiliary stirring shaft, ensuring structural stability. A limiting ring is provided on the auxiliary stirring shaft, which limits, supports, and fixes the outer fixing sleeve from below, further ensuring structural stability. An auxiliary ring is provided on the main stirring shaft, connected to the outer fixing sleeve via a first magnetic ring and a second magnetic ring. This ensures that the outer fixing sleeve is stably fixed to the auxiliary ring on the main stirring shaft during head replacement. The design prevents the outer fixing sleeve from slipping, further facilitating the replacement of the stirring head. Support rails are provided on both sides of the ball screw, and the lifting seat has through holes for these rails to pass through, ensuring structural stability. Limiting blocks at both ends of the support rails limit movement at the upper and lower ends of the lifting seat's sliding path, preventing over-movement and ensuring operational stability. Multiple evenly distributed annular anti-slip ridges on the outer surface of the outer fixing sleeve increase friction between the sleeve and external objects, facilitating rotation and ease of use. Therefore, this invention not only improves flexibility but also offers advantages such as high structural stability, long service life, ease of use, and high operational stability.

Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0018] Example. Using a highly flexible mixer for washable ceramic coatings, a structure is formed as follows: Figures 1 to 4 As shown, the system includes a base 1, a stirring motor 2, and a stirring tank 3. A stirring main shaft 4 is mounted on the stirring motor 2, and a first external thread section is provided on the outer surface of the end of the stirring main shaft 4. A stirring auxiliary shaft 5 is threadedly connected to the end of the stirring main shaft 4, and the end of the stirring auxiliary shaft 5 has a mounting groove for connecting to the stirring main shaft 4. A first internal thread section that mates with the first external thread section is provided on the inner wall of the mounting groove. A second external thread section with the opposite thread direction to the first thread section is provided on the outer surface of the stirring auxiliary shaft 5. An outer fixing sleeve 6 is threadedly connected to the second external thread section, and a second internal thread section that mates with the second external thread section is provided on the inner wall of the outer fixing sleeve 6. A stirring head 7 is mounted on the end of the stirring auxiliary shaft 5. Two symmetrically arranged lifting devices are mounted on the base 1, and a lifting seat 8 for mounting the stirring motor 2 is provided between the two lifting devices.

[0019] The stirring main shaft 4 is provided with a positioning groove 9 at its end; a positioning element 10 that cooperates with the positioning groove 9 is provided in the middle of the bottom surface of the mounting groove; a limiting ring 11 located directly below the second external thread section is provided on the stirring auxiliary shaft 5, and a first magnetic ring 12 is provided on the top surface of the limiting ring 11; an auxiliary ring 13 located directly above the first external thread section is provided on the stirring main shaft 4, the distance between the auxiliary ring 13 and the first external thread section is greater than the length of the outer fixing sleeve 6, and a first magnetic ring 12 is also provided on the bottom surface of the auxiliary ring 13; a second magnetic ring 14 is provided on both the upper and lower sides of the outer fixing sleeve 6, and the second magnetic ring 14 cooperates with the first magnetic ring 12; The lifting device includes a support base 15 vertically mounted on a base 1, and a ball screw 16 is provided on the side of the support base 15 facing the mixing tank 3. A servo motor 17 is connected to the end of the ball screw 16, and a sliding seat 18 is slidably mounted on the ball screw 16. The top surface of the sliding seat 18 is fixedly connected to the bottom surface of the lifting seat 8. Support rails 19 are provided on both sides of the ball screw 16, and limit blocks 20 are provided at both ends of each support rail 19. Two symmetrically arranged through holes are provided at both ends of the lifting seat 8. The support rails 19 are slidably disposed in the through holes. Multiple annularly distributed anti-slip ridges 22 are provided on the outer surface of the outer fixing sleeve 6.

[0020] Working Principle: During operation, first place the entire device on a horizontal surface and connect it to an external safe mains power supply. Then, place the mixing tank 3 directly below the mixing head 7. After placing the mixing tank 3, add the raw materials for the ceramic coating to be mixed into it. Once the raw materials are added, start the servo motor 17 in the forward direction. This will drive the ball screw 16 to rotate, which in turn will move the sliding seat 18 towards the bottom of the base 1. During this movement, the sliding seat 18 will also move the lifting seat 8, which in turn will move the mixing motor 2, the main mixing shaft 4, the secondary mixing shaft 5, and the mixing head 7 together, ultimately causing the main mixing shaft 4, secondary mixing shaft 5, and mixing head 7 to enter the mixing tank 3. Once the main mixing shaft 4, secondary mixing shaft 5, and mixing head 7 have entered the mixing tank 3 and reached a certain depth, stop the servo motor 17. The sliding seat 18 and the lifting seat 8 are stopped from moving, thus fixing the stirring head 7 at a fixed depth inside the mixing tank 3. Then, the stirring motor 2 is started, which drives the stirring main shaft 4 to rotate. The stirring main shaft 4 then drives the stirring secondary shaft 5 to rotate, which in turn drives the stirring head 7 to rotate, thereby mixing the ceramic coating raw materials inside the mixing tank 3. After the mixing is completed, the stirring motor 2 is stopped first, and then the servo motor 17 is started in reverse. After the servo motor 17 starts, it drives the ball screw 16 to rotate in reverse again, so that the sliding seat 18 can drive the lifting seat 8 and the stirring motor 2 and stirring head 7 on the lifting seat 8 to move upward together. Finally, the stirring head 7 is moved out of the mixing tank 3 from the top port. Then, the servo motor 17 is stopped, and the mixing tank 3 and the raw materials that have completed the mixing are moved out of the base 1, completing the unloading process.

[0021] When the mixing requirements of the raw materials requiring stirring change, the stirring head 7 needs to be replaced. First, ensure that the stirring head 7 is stopped and not inside the mixing tank 3. Then, fix the stirring sub-shaft 5 while simultaneously rotating the outer fixing sleeve 6. This creates a threaded connection between the second internal thread section on the outer fixing sleeve 6 and the second external thread section on the outer surface of the stirring sub-shaft 5, ultimately separating the outer fixing sleeve 6 from the stirring sub-shaft 5 and allowing it to move up and down on the stirring main shaft 4. Next, move the fixing sleeve 6 upwards until it contacts the auxiliary ring 13 on the stirring main shaft 4. The second magnetic ring 14 on the top surface of the outer fixing sleeve 6 engages with the first magnetic ring 12 on the auxiliary ring 13, allowing the outer fixing sleeve to move up and down. The fixed sleeve 6 can be stably attracted to the auxiliary ring 13, preventing the outer fixed sleeve 6 from slipping off during subsequent replacement and installation. Next, the stirring main shaft 4 is fixed and the stirring auxiliary shaft 5 is rotated, causing a threaded transmission between the first external thread section on the stirring main shaft 4 and the first internal thread section on the stirring auxiliary shaft 5. This allows the stirring auxiliary shaft 5 to be rotated away from the stirring main shaft 4 and removed. During the rotation of the stirring auxiliary shaft 5 away from the stirring main shaft 4, the positioning element 10 on the stirring auxiliary shaft 5 will slowly separate from the positioning groove 9. Finally, when the stirring main shaft 4 and the stirring auxiliary shaft 5 are completely separated, the positioning groove 9 and the positioning element 10 are also completely separated. Then, the stirring head 7, which meets the stirring requirements, is installed onto the stirring main shaft 4. During installation, the positioning element 10 is first aligned with the positioning groove 9. The process involves inserting the end portion of the main stirring shaft 4 into the mounting groove at the end of the auxiliary stirring shaft 5, then rotating the auxiliary stirring shaft 5. Utilizing the threaded connection between the first internal thread section and the first external thread section, the auxiliary stirring shaft 5 is stably threadedly connected to the main stirring shaft 4. Next, the outer fixing sleeve 6 is pulled down, separating it from the auxiliary ring 13 and allowing the top end of the auxiliary stirring shaft 5 to initially enter a small section of the outer fixing sleeve 6 from its bottom end. The auxiliary stirring shaft 5 is then fixed in place, and the outer fixing sleeve 6 is rotated until it is threaded onto the outer side of the end of the auxiliary stirring shaft 5. Finally, the bottom surface of the outer fixing sleeve 6 contacts the top surface of the limiting ring 11. The first magnetic ring 12 and the second magnetic ring 14 cooperate to enhance the external fixing... The tightness of the connection between sleeve 6 and the stirring sub-shaft 5; and because the thread orientation of the second external thread section on the outer fixed sleeve 6 is opposite to that of the first external thread section on the stirring main shaft 4, the two will have a mutual restraining effect during the actual operation, thereby ensuring that the stirring sub-shaft 5 can be stably installed on the stirring main shaft 4; during the entire stirring process, the start and stop of the stirring motor 2 and the servo motor 17 can be controlled by manually pressing a button, or by controlling an external setting on a controller. When using a controller, the controller can be a programmable controller such as FX2C-20MRD, Cortex-R8, or Cortex-M7, and the controller can be installed on the base 1;Furthermore, during the up-and-down movement of the lifting seat 8 driven by the sliding seat 18, the support rails 19 on both sides of the ball screw 16 guide and support the movement of the lifting seat 8, ensuring operational stability; moreover, the limit blocks at both ends of the support rails 19 can limit the movement of the lifting seat 8, preventing over-movement.
