Description

Technical Field

[0001] This invention relates to the field of coating processing technology, and more particularly to coating mixers. Background Technology

[0002] When mixing chemical or architectural coatings, different types of coatings need to be mixed and blended. The coating mixer is essentially designed to solve the fundamental problem of homogenization in coating preparation and use. Unstable operation of the coating mixer and coating sticking to the mixing shaft are common equipment problems. These not only affect mixing efficiency and product quality, but may also shorten the equipment life and even cause safety hazards.

[0003] In actual operation, unstable operation is mainly manifested as abnormal vibration, noise, and shaft oscillation. The root cause is usually the dynamic imbalance caused by the sticky material on the stirring shaft, wear or misalignment of key transmission components, and sudden changes in material load and viscosity. In addition, traditional simple stirring stations often rely on manual labor or simple limiters to place the material bucket without reliable mechanical clamping or locking devices. Under the radial force and vibration introduced by the stirring shaft, especially the high-speed dispersion shaft, the bucket is prone to slippage or paint splashing. Moreover, the paint is generally of an unspecified material, making it inconvenient to guide the stirring shaft to the edge of the bucket during the stirring process, resulting in the inability to guarantee the uniformity of mixing and fluctuations in product quality. At the same time, the adhesion and accumulation of high viscosity or solid content materials on the surface of the stirring shaft and blades not only significantly reduces the mixing efficiency and uniformity, but also increases the cleaning burden and the risk of cross-contamination of products, and can easily cause a series of chain problems such as equipment vibration, increased power consumption, and premature bearing damage. Summary of the Invention

[0004] This invention addresses the problems of unstable operation of paint mixers and paint residue adhering to the mixing shaft. The invention provides a paint mixer.

[0005] The technical solution adopted by the present invention to solve the above-mentioned technical problems is: a paint mixer, including a mixer body;

[0006] The mixer body has fixed handles on both sides, a connecting seat at the bottom of the mixer body, a drive shaft inside the connecting seat, a transmission shaft at the bottom of the connecting seat that is locked onto the drive shaft, a buffer tube at the top of the outer side of the transmission shaft, a docking ring inside the buffer tube, several telescopic shafts connecting the docking ring and the connecting seat, a set of connecting frames at the bottom of the buffer tube, and a support insert plate locked inside the connecting frames.

[0007] The buffer tube has a circular groove at its bottom, and a detection ring is installed inside the groove. The detection ring is concentric with the drive shaft and is used to detect the tilting or offset of the drive shaft. A rotating platform is installed on the outside of the support plate to abut against the top of the barrel and provide auxiliary support during the mixing process. This paint mixer improves the stability of operation and mixing quality through buffering and positioning design. Its anti-collision structure and self-cleaning function enhance durability and ease of maintenance. It also supports flexible adjustment of mixing depth and adaptability to multiple barrel sizes. In addition, integrated sensors can monitor the drive shaft offset in real time and provide early warnings to ensure the safe and stable operation of the equipment.

[0008] A further preferred embodiment of the present invention is as follows: a set of connecting plates is provided on the outside of the drive shaft, and a set of spiral blades is provided between the connecting plates. The surface of the spiral blades is provided with an anti-stick coating. A connecting ring frame is provided on the outside of the bottom connecting plate. An annular groove is opened on the outside of the connecting ring frame, and a protective ring is provided inside the annular groove. The spiral blades are the core stirring components. The anti-stick coating can effectively reduce the adhesion of the coating and facilitate cleaning. The connecting ring frame and the protective ring play a protective role, which can prevent the spiral blades from colliding and deforming with the barrel wall and reduce damage to the barrel body. At the same time, its structure facilitates thorough cleaning with a high-pressure water gun.

[0009] A further preferred embodiment of the present invention is as follows: a locking shaft is fitted at the bottom of the drive shaft. The locking shaft consists of a set of elastic pressure plates and elastic end blocks. A set of retaining rings is fitted around the locking shaft for limiting its movement. The locking shaft restricts the swing amplitude of the drive shaft inside the container, reducing wear caused by impacts. As a bottom fulcrum, the locking shaft can limit and buffer the swing amplitude of the drive shaft during stirring, reducing wear and impacts. Simultaneously, it allows the stirring shaft to move within a certain range, which helps to stir the edge area of ​​the container, eliminates mixing dead zones, and ensures uniform coating.

[0010] A further preferred embodiment of the present invention is as follows: the buffer tube has several transmission grooves on its edge, the docking ring has a threaded rod that moves inside the transmission grooves on its edge, the buffer tube has a fixed slide rail at its bottom, the fixed slide rail has slots on both sides, and a reset block is movably disposed inside the slots. The reset block has a hinge shaft on its top, and the hinge shaft is movably locked at the bottom of the docking ring. When the equipment vibrates, the hinge shaft drives the reset block to move within the slide rail, using the buffer pad to absorb energy, thereby effectively buffering the vibration and maintaining the stability of the stirring process and the life of the equipment.

[0011] A further preferred embodiment of the present invention is as follows: the bottom of the detection ring is provided with several docking grooves, and a cleaning shaft is inserted inside the symmetrical grooves. The cleaning shaft is in a continuous bending shape. The cleaning shaft is evenly arrayed on the outside of the transmission shaft. A plastic block is sleeved on the side of the cleaning shaft near the transmission shaft for auxiliary cleaning of the external part of the transmission shaft. Before the detection ring moves to perform detection, the cleaning shaft can pre-scrape and clean the debris and dried coating on the surface of the transmission shaft to prevent dirt from interfering with the subsequent sensor detection accuracy, and at the same time assist in daily maintenance.

[0012] A further preferred embodiment of the present invention is as follows: a plurality of pressure-sensitive sensors are provided inside the detection ring. The pressure-sensitive sensors are used to press against the outer wall of the transmission shaft. The detection ring detects the transmission shaft as it moves along with the buffer tube, and is used to detect the longitudinal displacement of the transmission shaft. This realizes intelligent monitoring of the operating status of the transmission shaft. By analyzing the change pattern of the pressure data of each sensor, it is possible to accurately determine whether the transmission shaft is in a normal, pure bending, overall translation, or complex deformation state, providing data basis for equipment maintenance and calibration, and preventing failures.

[0013] A further preferred embodiment of the present invention is as follows: hinged pressure plates are movably arranged on both sides of the connecting frame, a transmission frame is connected to the outer end of the hinged pressure plate, the transmission frame is symmetrically arranged on both sides of the connecting frame, a docking rod is inserted inside the transmission frame, a connecting pressure plate is connected to the side of the docking rod near the transmission shaft, and a grinding shaft is inserted on both sides of the connecting pressure plate;

[0014] The rear end of the hinged pressure plate is connected to a push plate, and the rear end of the connecting frame is provided with a positioning plate. Fixed shafts are connected to both ends of the positioning plate, and an elastic shaft connects the outer end of the fixed shaft to the push plate. A set of positioning inserts are connected to the positioning plate, and a support insert is engaged with the positioning insert for auxiliary positioning. When the support insert is engaged inside the connecting frame, it abuts against the push plate, driving the hinged pressure plate to abut against both sides of the support insert. At this time, the transmission frame moves outward with the hinged pressure plate to control the connecting pressure plate away from the transmission shaft. When the support insert is inserted, the cleaning mechanism disengages. After the support insert is pulled out, the cleaning mechanism automatically clamps the transmission shaft under the action of the elastic element, allowing it to move with the buffer tube to polish and clean its surface, which is convenient and quick.

[0015] A further preferred embodiment of the present invention is as follows: the connecting pressure plate has several straight grooves in the middle, and a partition plate is installed inside the straight grooves. The partition plate abuts against the surface of the drive shaft to control the gap between the grinding shaft and the drive shaft. This can clean residual paint on the surface while reducing damage to the paint coating. As a gap control component, the partition plate can accurately adjust the distance between the grinding shaft and the drive shaft surface, which can effectively clean residual paint and avoid excessive grinding that could damage the body coating of the drive shaft, thus protecting the equipment.

[0016] A further preferred embodiment of the present invention is as follows: a set of tension shafts is provided outside the support plate, and a fixed end block is connected to the outer end of the tension shafts. The rotary table is rotatably disposed outside the fixed end block, and a set of straight plates located on both sides of the fixed end block are connected to the rotary table. Positioning holes for inserting limiting pins are provided on both the fixed end block and the straight plates. The tension shafts can adapt to barrels of different diameters and have strong versatility. The design of the rotary table allows the mixer to reciprocate at a certain angle in the supported state. This dynamic mixing method can further promote the uniform mixing of the coating in the barrel and improve the mixing quality.

[0017] A further preferred embodiment of the present invention is as follows: a movable seat is movably mounted on one side of the rotating platform, a limiting ball is connected to the bottom of the movable seat, a set of positioning end blocks are mounted on the bottom of the rotating platform, and a fixing rod with a rubber tube sleeve is provided at the bottom of the positioning end blocks. The fixing tube is used to cooperate with the limiting ball to be mounted on the edge of the barrel. By clamping from both the inside and outside of the barrel, the mixer can be stably installed on the edge of the barrel. During operation, when the rotating platform is locked, the bottom of the barrel is pressed down, which plays a limiting role, effectively preventing the equipment from shifting or the barrel from tipping over during the mixing process, reducing paint splashing, and ensuring operational safety.

[0018] Compared with the prior art, the advantages of the present invention are as follows:

[0019] 1. This invention effectively reduces the vibration of the transmission shaft caused by shock during the mixing process through the synergistic action of the buffer tube, telescopic shaft and reset block, making the mixing operation more stable. With the auxiliary positioning design of the support plate and the rotating table, the mixer can be firmly pressed against the edge of the barrel, further reducing the overall shaking, thereby improving the uniformity of coating mixing and avoiding the occurrence of mixing dead corners.

[0020] 2. The present invention provides a connecting ring frame and a protective ring around the drive shaft to prevent the spiral blades from directly colliding with the inner wall of the barrel, reducing the risk of blade deformation or damage. The clamping shaft and hoop structure can limit excessive swing of the drive shaft and reduce wear. At the same time, the anti-stick coating on the surface of the spiral blades can reduce paint residue, extend the cleaning cycle, and improve the service life of the components.

[0021] 3. The present invention uses a lockable telescopic shaft structure, which allows users to flexibly adjust the stirring position of the drive shaft according to the depth of the bucket. The tension shaft on the support plate can be used to adapt to bucket openings of different diameters. The rotary table and movable seat, together with the limiting ball and fixing rod, can quickly fix the mixer to the edge of the bucket, simplifying the installation and positioning steps and improving operating efficiency.

[0022] 4. After the mixing is completed, the support plate can be detached, so that the connecting pressure plate automatically fits the surface of the drive shaft under the action of the elastic mechanism. The residual dried coating is cleaned by the grinding shaft. The cleaning shaft set inside the detection ring can remove dirt from the surface of the drive shaft in advance before detection. The high-pressure water gun washes the stirring blades with residual undried coating, which greatly reduces the difficulty of maintenance and keeps the drive shaft clean.

[0023] 5. The multiple pressure-sensitive sensors integrated within the detection ring of this invention can detect the pressure distribution on the surface of the drive shaft in real time. By analyzing the data changes, it can determine whether bending, translation, or combined displacement has occurred. This monitoring mechanism can convert physical deformation into analyzable electrical signals, helping users to understand the equipment's operating status in a timely manner, intervene and correct in advance, and ensure the safety and stability of the stirring process.

[0038] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0039] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0040] This embodiment mainly describes the title of the paint mixer; please refer to [link / reference]. Figures 1-12 Specifically, the paint mixer is characterized by comprising a mixer body 1;

[0041] The mixer body 1 has fixed handles 11 connected to both sides. The bottom of the mixer body 1 has a connecting seat 12. The connecting seat 12 has a drive shaft inside. The bottom of the connecting seat 12 has a transmission shaft 2 that is locked onto the drive shaft. The top of the outer side of the transmission shaft 2 has a buffer tube 3. The buffer tube 3 has a docking ring 31 inside. Several telescopic shafts 32 are connected between the docking ring 31 and the connecting seat 12. The bottom of the buffer tube 3 has a set of connecting frames 4. The connecting frames 4 have a support plate 5 locked inside.

[0042] The buffer tube 3 has a circular groove at its bottom, and a detection ring 36 is installed inside the groove. The detection ring 36 is concentric with the drive shaft 2 and is used to detect the tilting or offset of the drive shaft 2. A rotating platform 53 is installed on the outside of the support plate 5 to abut against the top of the barrel and provide auxiliary support during the mixing process. The paint mixer improves the stability of operation and the mixing quality through buffering and positioning design. Its anti-collision structure and self-cleaning function enhance its durability and ease of maintenance. It also supports flexible adjustment of mixing depth and adaptability to multiple barrel sizes. In addition, the integrated sensor can monitor the drive shaft offset in real time and provide early warning to ensure the safe and stable operation of the equipment.

[0043] like Figure 2 and Figure 3 As shown, a set of connecting plates is provided on the outside of the drive shaft 2, and a set of spiral blades 22 are provided between the connecting plates. The surface of the spiral blades 22 is provided with an anti-stick coating to reduce the adhesion of paint residue during actual use. A connecting ring frame 21 is provided on the outside of the bottom connecting plate. The connecting ring frame 21 can prevent the spiral blades 22 from colliding with the edge of the barrel during the stirring process, and reduce the deformation of the spiral blades 22 during use, which affects the stirring efficiency. The connecting ring frame 21 has an annular groove on its outside, and a protective ring is provided inside the annular groove. The protective ring can reduce the damage caused by the connecting ring frame 21 colliding with the barrel during the stirring process. After the stirring process is completed, the edges and dead corners of the spiral blades 22 are impacted by a high-pressure water gun to reduce the residue.

[0044] like Figure 2 and Figure 3 As shown, a locking shaft 23 is fitted at the bottom of the drive shaft 2. The locking shaft 23 consists of a set of elastic pressure plates and elastic end blocks. A set of retaining rings 24 are fitted on the outside of the locking shaft 23. The locking shaft 23 restricts the swing amplitude of the drive shaft 2 inside the barrel, reducing wear caused by collisions. The locking shaft 23 can act as a buffer during the swing of the stirring shaft 2 inside the barrel. The locking shaft 23 can also be used to hold against the edge of the barrel. In actual operation, it is not necessary to control the range of motion, which can reduce the unexpected situation of uneven mixing due to dead corners inside the barrel.

[0045] like Figure 4 and Figure 5As shown, the buffer tube 3 has several transmission grooves on its edge, and the docking ring 31 has a threaded rod that moves inside the transmission groove. The docking ring 31 can move within the range of the transmission groove. With the help of the bottom buffer mechanism, the impact of vibration during the stirring process can be reduced. The bottom of the buffer tube 3 has a fixed slide rail 33. The fixed slide rail 33 has slots on both sides, and a reset block 34 is movably installed inside the slot. The top of the reset block 34 has a hinge shaft 35. The hinge shaft 35 is movably locked at the bottom of the docking ring 31. When the bottom rotating table 53 is locked at the edge of the barrel, the operator can adjust and lock the telescopic shaft 32 to determine the stirring depth. In actual operation, if the main body of the equipment vibrates, the reset block 34 can be moved by the hinge shaft 35. The side of the reset block 34 that contacts the buffer tube 3 has a buffer pad, which can buffer under continuous vibration and maintain the stability during the stirring process.

[0046] like Figure 11 and Figure 12 As shown, the bottom of the detection ring 36 has several mating grooves, and a cleaning shaft 37 is inserted into the symmetrical grooves. The cleaning shaft 37 is continuously bent and is evenly arrayed on the outside of the transmission shaft 2. The cleaning shaft 37 can play an auxiliary cleaning role before the pressure sensor 38 measures, and during the movement of the buffer tube 3 outside the transmission shaft 2, it can reduce the adhesion of debris or dirt and affect subsequent detection. A plastic block is sleeved on the side of the cleaning shaft 37 near the transmission shaft 2 for auxiliary cleaning of the outside of the transmission shaft 2. The plastic block can also play a cleaning role by adhering to the outside of the transmission shaft 2, which can reduce the adhesion of paint after drying.

[0047] like Figure 12 As shown, the detection ring 36 is equipped with several pressure sensors 38. The pressure sensors 38 are used to press against the outer wall of the transmission shaft 2. The detection ring 36 detects the transmission shaft 2 as it moves with the buffer tube 3. It is used to detect the longitudinal displacement of the transmission shaft 2. During the detection process, the pressure sensors 38 can provide feedback based on the changes in the readings. This transforms the measurement of geometric deformation into a relatively simple distributed pressure measurement problem. The data-driven method is used to effectively monitor the bending, displacement and vibration of the straight rod.

[0048] When the data fed back by all pressure sensors 38 are basically consistent and small, it indicates that no offset has occurred. When the data of a symmetrical pair of pressure sensors 38 changes significantly, i.e., the pressure on one side increases while the pressure on the other side decreases or remains unchanged, it indicates that pure bending has occurred. When the data of pressure sensors 38 in a single direction or sector continues to increase while the data of the pressure sensors 38 on the opposite side remains unchanged, it indicates that the drive shaft 2 has shifted in one direction as a whole. When the data pattern is asymmetrical, more complex vector synthesis is required for analysis, i.e., the drive shaft 2 is simultaneously shifting and bending. Based on the estimated situation, subsequent corrections can be made and the shaft can be put back into use. This can effectively diagnose the overall offset type and provide a basis for subsequent accurate corrections and safe reuse.

[0049] like Figure 8 and Figure 9 As shown, hinged pressure plates 41 are movably arranged on both sides of the connecting frame 4. The outer end of the hinged pressure plates 41 is connected to the transmission frame 42. The transmission frame 42 is symmetrically arranged on both sides of the connecting frame 4. The transmission frame 42 is fitted with a docking rod 431. The docking rod 431 is connected to a connecting pressure plate 43 on the side near the transmission shaft 2. The connecting pressure plate 43 is fitted with a grinding shaft 45 on both sides. The grinding shaft 45 is equipped with several abrasive balls, which can clean the dried coating residue on the surface of the transmission shaft 2 and reduce the accumulation of coating. During the operation of the transmission shaft 2, the coating will vortex due to the centrifugal effect of the stirring blades 22. The coating adheres to the part of the transmission shaft 2 and is continuously exposed to the air, which makes the coating on the surface easy to dry and accumulate. Regular maintenance and cleaning are required. Otherwise, if the dried coating is too thick, it will not only be difficult to peel off, but it will also easily cause wear to the coating or paint on the surface of the transmission shaft 2.

[0050] A push plate is connected to the rear end of the hinged pressure plate 41, and a positioning plate 46 is provided at the rear end of the connecting frame 4. Fixed shafts 461 are connected to both ends of the positioning plate 46. An elastic shaft is connected between the outer end of the fixed shaft 461 and the push plate to drive the hinged pressure plate 41 to reset. A set of positioning inserts 462 is connected to the positioning plate 46. A support insert 5 is engaged with the positioning inserts 462 for auxiliary positioning. The cooperation between the positioning inserts 462 and the support inserts 5 increases the stability of the subsequent support for the barrel and reduces the possibility of unilateral loosening. When plate 5 is inserted into the connecting frame 4, it abuts against the push plate, which drives the hinged pressure plate 41 to abut against both sides of the support plate 5. At this time, the transmission frame 42 moves outward with the hinged pressure plate 41 to control the connecting pressure plate 43 away from the transmission shaft 2. After the mixing of the coating is completed, the support plates 5 on both sides can be removed. At this time, the push plate can be pulled back to its original position by means of the elastic shaft. During the resetting process of the hinged pressure plate 41, the connecting pressure plate 43 can be pressed against the outside of the transmission shaft 2, and can clean the outer wall of the transmission shaft 2 by moving with the buffer tube 3.

[0051] like Figure 8As shown, the connecting pressure plate 43 has several straight grooves in the middle, and a partition plate 44 is installed inside the straight grooves. The partition plate 44 abuts against the surface of the drive shaft 2 and is used to control the gap between the grinding shaft 45 and the drive shaft 2. This can clean the residual paint on the surface while reducing damage to the paint coating. With the help of the partition plate 44, the gap between the connecting pressure plate 43 and the surface of the drive shaft 2 can be controlled. In the subsequent grinding and cleaning process, the amount of grinding of the abrasive balls set on the grinding shaft 45 can be controlled, reducing the accidental damage to the surface coating.

[0052] like Figure 7 and Figure 10 As shown, a set of tension shafts 51 are provided on the outside of the support plate 5. The length of the tension shafts 51 can be adjusted according to the actual diameter of the barrel to hold the mixer against the top of the barrel, which can play a limiting role. Compared with the traditional external positioning components, it is more convenient and faster. The outer end of the tension shafts 51 is connected to a fixed end block 52. The rotating table 53 is rotatably set on the outside of the fixed end block 52. A set of straight plates located on both sides of the fixed end block 52 are connected to the rotating table 53. The fixed end block 52 and the straight plates are provided with positioning holes for inserting limiting pins. During the mixing process, the limiting pins can be removed according to actual needs, which can make the mixer set inside the rotating table 53 swing back and forth, reducing the uneven mixing of the coating inside the barrel.

[0053] Additionally, it should be noted that the support plate 5 can be disassembled according to actual usage, enhancing the flexibility of the equipment and its adaptability to various usage scenarios. Compared with traditional external positioning devices, it eliminates the need for additional accessories, significantly improving installation efficiency and ease of operation. During mixing operations, if a stronger mixing effect is required, the operator can remove the limit pin at any time, allowing the mixer mounted on the rotary table 53 to reciprocate at a certain angle, thereby effectively agitating the fluid inside the container and preventing the coating from settling or becoming unevenly mixed in certain areas.

[0054] like Figure 10 As shown, a movable seat 54 is movably mounted on one side of the rotating table 53. A limit ball is connected to the bottom of the movable seat 54. A set of positioning end blocks 55 are mounted on the bottom of the rotating table 53. A fixing rod with a rubber tube is provided at the bottom of the positioning end block 55. The fixing tube is used to cooperate with the limit ball to be mounted on the edge of the barrel. During the positioning process, the fixing rod with the rubber tube can be mounted on the inner wall of the barrel. Pulling the movable seat 54 at the top moves the limit ball against the outer wall of the barrel, which plays an auxiliary support role. The paint mixer can be placed on the top of the barrel. During the mixing process, it can assist in limiting the movement of the barrel or the splashing of paint inside due to bumps during the mixing process. When a small amount of paint is mixed, the rotating table 53 can be locked. The operator can press the mixer on the top of the barrel to tighten it and reduce the possibility of the barrel, which is light in weight, easily shifting and tipping over.

[0055] In the description of this invention, it should be noted that the terms "upper," "lower," "front," "rear," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product of this invention is usually placed when in use. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0056] The present invention has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only for the purpose of helping to understand the present invention and its core ideas. It should be noted that for those skilled in the art, several improvements and modifications can be made to the present invention without departing from the principles of the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
