Description

Technical Field

[0001] This utility model relates to the field of coating production technology, and in particular to a composite water-based coating mixing device. Background Technology

[0002] In the preparation of water-based coatings, a stirring device is needed to properly proportion the coating raw materials, which are then blended into the desired finished product through a stirring process. Water-based coatings, especially composite water-based coatings, often contain multiple components, which may form lumps or agglomerates during mixing, affecting the uniformity and final performance of the coating. Therefore, thorough stirring is necessary during the mixing process to ensure the uniformity and quality of the coating.

[0003] Traditional paint mixing devices may have several problems, such as uneven mixing, poor agglomeration and breakup, and incomplete filtration, all of which can affect the final quality of the paint. To solve these problems, a more efficient and stable composite water-based paint mixing device needs to be designed. Utility Model Content

[0004] The purpose of this invention is to provide a composite water-based coating mixing device that solves the above-mentioned problems.

[0005] This utility model is achieved through the following technical solution:

A coarse filter screen of the same size as the feed inlet is installed on the end side wall of the feed inlet. An agglomeration breaking assembly is installed on the side wall of the feed inlet above the coarse filter screen, closely attached to the coarse filter screen. A fine filter screen is installed in the upper half of the device body. A mixing and stirring assembly is installed at the bottom of the device body below the fine filter screen. A discharge port is installed on the outer side of the bottom of the device body.

[0007] Furthermore,

[0008] The feed inlet includes an installation port and a limiting slide. The coarse filter screen installed inside the feed inlet has an annular installation port on its upper side wall. The annular installation port penetrates the side wall of the feed inlet. The opposite wall of the annular installation port is provided with a limiting slide facing opposite directions. The sum of the heights of the two limiting slides is less than the height of the installation port.

[0009] Furthermore,

[0010] The agglomeration crushing component includes a crushing gear, a chute, and crushing blades. The crushing gear has chutes on both its upper and lower surfaces. The chute and the limiting slide are matched and fitted at the installation port. The crushing blades are vertically arranged on the tooth grooves on the outside of the crushing gear and the inner ring of the crushing gear in contact with the drive component. The size of the inner ring of the crushing gear is exactly the same as the size of the feed port.

[0011] Furthermore,

[0012] The drive assembly includes a drive motor, a rotating rod, a bearing, and a transmission gear. The drive motor is located on the upper surface of the thickened plate at the top of the device body next to the feed inlet. The output end of the drive motor is vertically connected to the rotating rod, which passes through the upper surface of the thickened plate at the top of the device body and enters the cavity. One end of the rotating rod is connected to the bearing at the bottom of the cavity. The transmission gear is fixed on the rotating rod and is at the same height as the crushing gear and is matched.

[0013] Furthermore,

[0014] The mixing assembly includes a mixing motor, a mixing shaft, and mixing blades.

[0015] Furthermore,

[0016] A threaded ring is fixedly installed at the feed inlet of the device body, and the threaded ring is connected to the feed funnel. A viewing window for observing the fine filter screen is also provided on the side of the device body.

[0017] The beneficial effects of this utility model are:

[0018] 1. The dual filtration design with coarse and fine filters effectively removes large particles and fine impurities from the paint, ensuring its purity. The agglomeration breaking component is closely attached to the coarse filter, using crushing gears and blades to break down agglomerates, further improving the uniformity of the raw materials and preventing agglomeration from affecting paint quality.

[0019] 2. The thickened plate design on the top of the device body not only enhances the stability and load-bearing capacity of the overall structure, but also provides ample installation space for the drive assembly and agglomeration crushing assembly. Meanwhile, the threaded ring design at the feed inlet makes the connection of the feed funnel simpler and more reliable, facilitating disassembly and cleaning, thus improving the ease of use and maintenance efficiency of the device.

[0030] Example

[0031] See Figures 1 to 4 :

[0032] A composite water-based coating mixing device includes a device body 1. The top of the device body 1 is a thickened plate 10 with a hollow structure 101. A drive assembly 3 is installed from the upper surface of the thickened plate 10 to its inner cavity. A feed inlet 4 is opened next to the drive assembly 3. A coarse filter 6 of the same size as the feed inlet 4 is installed on the end side wall of the feed inlet 4. An agglomeration breaking assembly 5 is installed on the side wall of the feed inlet 4 above the coarse filter 6. The agglomeration breaking assembly 5 is close to the coarse filter 6. A fine filter 7 is installed in the upper half of the device body 1. A mixing and stirring assembly 2 is installed at the bottom of the device body 1 below the fine filter 7. A discharge port 8 is installed on the outer side of the bottom of the device body 1.

[0033] The top of the device body 1 is designed as a thickened plate 10 with a hollow structure 101 to enhance the stability and load-bearing capacity of the structure, while providing installation space for the drive assembly 3. The drive assembly 3 is installed on the top thickened plate 10, which can effectively utilize the space and transmit power to the agglomeration crushing assembly 5 on one side through the hollow structure 101. The coarse filter 6 is installed at the end of the feed inlet 4 to filter out agglomerates of water-based paint, while the agglomeration crushing assembly 5 crushes the agglomerates. The fine filter 7 then performs a secondary filtration of the water-based paint to remove fine impurities.

[0034] Furthermore,

[0035] The feed inlet 4 includes an installation port 41 and a limiting slide 42. The coarse filter 6 installed in the feed inlet 4 has an annular installation port 41 on its upper side wall. The annular installation port 41 penetrates the side wall of the feed inlet 4. The opposite wall of the annular installation port 41 is provided with a limiting slide 42 facing each other. The sum of the heights of the two limiting slides 42 is less than the height of the installation port 41.

[0036] The limiting slide 42 can limit the agglomeration crushing component 5 to prevent displacement during operation. The height of the two limiting slides 42 is less than the height of the installation port 41 to provide a certain installation space for the agglomeration crushing component 5. The limiting slide 42 and the agglomeration crushing component 5 are tightly connected to achieve a seal, preventing water-based coating from overflowing from the connection between the limiting slide 42 and the agglomeration crushing component 5 during the feeding process.

[0037] Furthermore,

[0038] The agglomeration crushing component 5 includes a crushing gear 50, a chute 51, and a crushing blade 52. The crushing gear 50 has chute 51 on both its upper and lower surfaces. The chute 51 and the limiting slide 42 are matched and fitted at the mounting port 41. The tooth groove on the outside of the crushing gear 50 is in contact with the drive component 3. The crushing blade 52 is vertically arranged on the inner ring of the crushing gear 50, and the size of the inner ring of the crushing gear 50 is exactly the same as the size of the feed port 4.

[0039] The agglomeration crushing component 5, through the cooperation of the crushing gear 50 and the crushing blade 52, can effectively crush agglomerates. The crushing gear 50 is installed by matching the limiting slide 42 through the slide groove 51 to ensure its stable operation. The crushing blade 52 is vertically set in the inner ring of the crushing gear 50, which can efficiently cut agglomerates and ensure the fineness of the raw materials. The crushing blade 52 can be set with multiple layers to enhance the cutting ability. The inner ring of the crushing gear 50 is the same size as the feed inlet 4, mainly to make full use of the space of the feed inlet 4 and avoid the inner ring of the crushing gear 50 being smaller than the size of the feed inlet 4, which would block part of the coarse filter screen 6 in the feed inlet 4 and reduce the feeding rate.

[0040] Furthermore,

[0041] The drive assembly 3 includes a drive motor 30, a rotating rod 31, a bearing 32, and a transmission gear 33. The drive motor 30 is located on the upper surface of the thickened plate 10 at the top of the device body 1, next to the feed inlet 4. The output end of the drive motor 30 is vertically connected to the rotating rod 31, which passes through the upper surface of the thickened plate 10 at the top of the device body 1 and enters the cavity. One end of the rotating rod 31 is connected to the bearing 32 at the bottom of the cavity. The transmission gear 33 is fixed on the rotating rod 31, and the transmission gear 33 is at the same height as the crushing gear 50 and is matched.

[0042] The drive assembly 3 transmits power to the crushing gear 50 through the cooperation of the drive motor 30, the rotating rod 31 and the transmission gear 33, driving the crushing gear 50 to rotate. At the same time, it drives the crushing blade 52 set in the inner ring of the crushing gear 50 to rotate, thereby cutting and crushing the agglomerates. The transmission gear 33 is at the same height as the crushing gear 50 and is matched to ensure the smoothness and efficiency of power transmission, thereby ensuring the normal operation of the agglomerate crushing assembly 5.

[0043] Furthermore,

[0044] The mixing assembly 2 includes a stirring motor 20, a stirring shaft 21, and a stirring blade 22. The stirring motor 20 is installed at the bottom center of the device body 1. The stirring shaft 21 passes through the bottom of the device and is connected to the stirring motor 20. The stirring blade 22 is fixedly connected to the stirring shaft 21.

[0045] The mixing assembly 2, through the cooperation of the mixing motor 20, the mixing shaft 21, and the mixing blades 22, thoroughly mixes the filtered raw materials. The mixing blades 22 are fixed on the mixing shaft 21, and their rotation ensures thorough mixing of the coating, thereby improving product quality.

[0046] Furthermore,

[0047] A threaded ring 9 is fixedly provided at the feed inlet 4 of the device body 1, and is connected to the feed funnel 11 through the threaded ring 9. A viewing window for observing the fine filter screen 7 is also provided on the side of the device body 1.

[0048] The threaded ring 9 at the feed inlet 4 of the device body 1 is used to connect the feed funnel 11, facilitating the addition of raw materials. The threaded connection is simple and reliable, easy to disassemble and clean, improving the ease of use and maintenance efficiency of the device; the viewing window allows for a direct view during the feeding process to see whether the added coating is about to contact the fine filter screen 7, preventing the fine filter screen 7 from being submerged by the added coating.

[0049] The principle of this utility model:

[0050] The composite water-based coating mixing device achieves efficient mixing and filtration of coatings through the coordinated operation of multiple components. First, the coating enters the device through inlet 4. A coarse filter 6 initially filters out large agglomerates. The agglomerate crushing component 5, closely attached to the coarse filter 6, uses crushing gears 50 and crushing blades 52 to pulverize the agglomerates, ensuring the uniformity of the raw material. Subsequently, the raw material undergoes secondary filtration through a fine filter 7 to remove fine impurities. The drive component 3 drives the crushing gear 50 to rotate via transmission gear 33, ensuring a smooth and efficient crushing process. The mixing and stirring component 2, through the cooperation of a stirring motor 20, stirring shaft 21, and stirring blades 22, thoroughly mixes the filtered coating, ensuring uniform coating quality. The thickened plate 10 on the top of the device body 1 enhances structural stability and provides installation space for the agglomerate crushing component 5 and the drive component 3. Simultaneously, the threaded ring 9 of the inlet 4 facilitates the connection of the feeding funnel 11 for adding coatings to the device, while the viewing window allows for easy observation of the feeding process and prevents the fine filter 7 from being submerged.
