Abstract
Description
Technical Field
[0001] This utility model relates to the field of coating industry media technology, specifically to an online coating industry media adding device. Background Technology
[0002] In the coating industry, the mixing quality of coating media plays a decisive role in the final coating effect.
[0003] Traditional methods of adding and mixing coating media have many drawbacks, severely impacting production efficiency and product quality. Firstly, traditional mixing equipment has a simple stirring structure, relying solely on a simple stirring rod, making it difficult to ensure thorough and uniform mixing of the media. This leads to significant differences in coating effects between batches, affecting product quality stability. Secondly, during mixing, the media easily adheres to the inner wall of the mixing tank, not only wasting media and increasing production costs but also affecting subsequent mixing results. Furthermore, cleaning the media adhering to the inner wall is extremely difficult, requiring considerable time and manpower, reducing production efficiency. In addition, traditional equipment lacks effective internal cleaning devices; after each production cycle, residual media inside the mixing tank is difficult to completely remove. Over time, this accumulation can breed bacteria, affecting normal equipment operation and causing cross-contamination of different types of media in subsequent production, thus impacting product quality. Therefore, we propose an online media addition device for the coating industry. Utility Model Content
[0004] The purpose of this invention is to provide an online coating medium addition device to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: It includes a mixing chamber, with several supports evenly fixedly installed at the bottom of the mixing chamber. A rotating shaft is rotatably mounted inside the mixing chamber via bearings. Several first stirring rods are evenly fixedly installed on the rotating shaft inside the mixing chamber. A discharge pipe is provided at the bottom of the mixing chamber, and a valve is fixedly installed on the discharge pipe. A support rod is fixedly installed at the outer end of each of the first stirring rods. A limit plate is fixedly installed at the outer end of the support rod. A sleeve is slidably fitted on the outer side of the limit plate. A scraper is fixedly installed on the outer wall of the sleeve, with the scraper's sidewall contacting the inner wall of the mixing chamber. A return spring is fixedly installed on the inner wall of the sleeve, with one end of the return spring fixedly connected to the limit plate and the other end connected to the inner wall of the sleeve.
[0006] Preferably, a fixing frame is fixedly installed on the side wall of the mixing box away from the feed inlet, and a pump is provided on the top of the fixing frame. A water tank is fixedly installed on the top side of the mixing box away from the feed inlet. A diversion pipe is fixedly installed on the inner wall above the mixing box, and several nozzles are evenly arranged on the diversion pipe. The water tank is connected to the diversion pipe through a conduit and a pump. A water inlet is also provided on the water tank.
[0007] Preferably, a plurality of mounting brackets are also uniformly fixedly installed on the rotating shaft, and a rotating shaft is rotatably mounted on the mounting brackets via bearings, and a plurality of second stirring rods are uniformly fixedly installed on the rotating shaft.
[0008] Preferably, a feed inlet is fixedly installed on one side of the top of the mixing box, and a detachable sealing plate is inserted into the feed inlet.
[0009] Preferably, a mounting shell is fixedly installed on the top of the mixing tank, the rotating shaft passes through the mounting shell and extends into the interior of the mounting shell, a drive shaft is rotatably mounted on the mounting shell via a bearing, the drive shaft passes through the water tank and extends into the interior of the water tank, a first bevel gear is keyed to the drive shaft inside the mounting shell, a second bevel gear is keyed to the rotating shaft inside the mounting shell, the second bevel gear meshes with the first bevel gear, and a plurality of third stirring rods are uniformly fixedly mounted on the drive shaft inside the water tank.
[0010] Preferably, a drive motor is fixedly installed on one side of the outer wall of the mounting housing, and the power output shaft of the drive motor is fixedly connected to the drive shaft through a coupling.
[0011] Compared with existing technologies, the beneficial effects of this utility model are as follows: The rotating shaft drives the first stirring rod to initially stir the coating industrial media in the mixing tank. Simultaneously, the mounting bracket on the rotating shaft drives the rotating shaft and the second stirring rod to rotate, achieving multi-level and multi-directional stirring, greatly improving the uniformity of media mixing, effectively avoiding coating quality problems caused by uneven mixing, and ensuring the stability of product quality. Furthermore, the scraper at the outer end of the first stirring rod can scrape off the coating industrial media adhering to the inner wall of the mixing tank when the rotating shaft rotates, reducing media waste and lowering production costs. This reduces production costs and avoids the impact of residual media on subsequent mixing effects. The return spring design ensures that the scraper is always in close contact with the inner wall of the mixing tank, improving the scraper's efficiency and cleaning effect. In addition, the water tank is connected to the distribution pipe and nozzles inside the mixing tank through a pump. After production, the pump can be started to spray the cleaning water in the water tank through the nozzles to thoroughly spray and clean the inside of the mixing tank. When used in conjunction with the scraper, it can thoroughly remove residual media in the mixing tank, prevent bacterial growth and cross-contamination of different types of media, and ensure the normal operation of the equipment and the quality of subsequent production.
[0012] In addition, the third stirring rod on the drive shaft can stir the water and detergent in the water tank, making them fully mixed and improving the cleaning power of the cleaning water. Attached Figure Description

Detailed Implementation
[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] This utility model provides a technical solution: such as Figures 1-4 The illustrated online coating industrial media addition device includes a mixing tank 1. Several supports 2 are evenly fixedly installed at the bottom of the mixing tank 1. The supports 2 improve the stability of the mixing tank 1, thereby ensuring the efficiency of the mixing tank 1. A feed inlet 3 is fixedly installed on one side of the top of the mixing tank 1. A detachable sealing plate 4 is inserted into the feed inlet 3. The feed inlet 3 facilitates the addition of coating industrial media into the mixing tank 1. At the same time, the sealing plate 4 reduces the occurrence of coating industrial media overflowing from the feed inlet 3 during mixing, thereby ensuring the efficiency of the mixing tank 1.
[0020] Inside the mixing tank 1, a rotating shaft 5 is rotatably mounted via bearings. Several first stirring rods 6 are uniformly fixedly installed on the rotating shaft 5 inside the mixing tank 1. Under the action of the first stirring rods 6, the coating industrial media inside the mixing tank 1 can be mixed, thereby ensuring the mixing efficiency between the coating industrial media. A discharge pipe 15 is provided at the bottom of the mixing tank 1, and a valve 16 is fixedly installed on the discharge pipe 15. After the coating industrial media is mixed inside the mixing tank 1, the valve 16 can be opened to discharge the mixed coating industrial media.
[0021] A support rod 7 is fixedly installed at the outer end of the first stirring rod 6. A limiting plate 8 is fixedly installed at the outer end of the support rod 7. A sleeve 9 is slidably sleeved on the outer side of the limiting plate 8. A scraper 10 is fixedly installed on the outer wall of the sleeve 9. The side wall of the scraper 10 contacts the inner wall of the mixing box 1. When the rotating shaft 5 rotates, it can drive the scraper 10 to rotate, thereby scraping off the coating industrial medium adhering to the inner wall of the mixing box 1. This reduces the occurrence of coating industrial medium adhering to the inner wall of the mixing box 1 and affecting the subsequent use of the mixing box 1, thus ensuring the efficiency of the device. A return spring 11 is fixedly installed on the inner wall of the sleeve 9. One end of the return spring 11 is fixedly connected to the limiting plate 8, and the other end of the return spring 11 is connected to the inner wall of the sleeve 9. At this time, under the action of the return spring 11, the contact quality between the scraper 10 and the inner wall of the mixing box 1 is ensured, thereby ensuring the efficiency of the scraper 10.
[0022] Several mounting brackets 12 are also evenly fixedly installed on the rotating shaft 5. A rotating shaft 13 is rotatably mounted on the mounting bracket 12 via bearings. Several second stirring rods 14 are evenly fixedly installed on the rotating shaft 13. Under the action of the second stirring rods 14, the coating industrial medium can be further stirred and mixed, thereby ensuring the mixing efficiency of the mixing box 1 for the coating industrial medium.
[0023] A fixing frame 17 is fixedly installed on the side wall of the mixing tank 1 away from the feed inlet 3. A pump 20 is installed on the top of the fixing frame 17. A water tank 18 is fixedly installed on the top side of the mixing tank 1 away from the feed inlet 3. A diversion pipe 21 is fixedly installed on the inner wall above the mixing tank 1. Several nozzles 22 are evenly arranged on the diversion pipe 21. The water tank 18 is connected to the diversion pipe 21 through a conduit and the pump 20. When it is necessary to clean the inside of the mixing tank 1, the operator can start the pump 20 to introduce the cleaning water in the water tank 18 into the diversion pipe 21 through the conduit, and then spray it out from the nozzles 22, thereby realizing the function of spraying and cleaning the inside of the mixing tank 1. When used with the scraper 10, it can ensure the quality of cleaning the inside of the mixing tank 1. The water tank 18 is also provided with a water inlet 19, which facilitates the addition of cleaning water to the water tank 18.
[0024] A mounting shell 23 is fixedly installed on the top of the mixing tank 1. A rotating shaft 5 passes through the mounting shell 23 and extends into the interior of the mounting shell 23. A drive shaft 24 is rotatably mounted on the mounting shell 23 via bearings. The drive shaft 24 passes through the water tank 18 and extends into the water tank 18. A first bevel gear 26 is keyed onto the drive shaft 24 inside the mounting shell 23. A second bevel gear 27 is keyed onto the rotating shaft 5 inside the mounting shell 23. The second bevel gear 27 meshes with the first bevel gear 26. Rotating the drive shaft 24 allows the first bevel gear 26 and the second bevel gear 27 to mesh. 7 drives the rotating shaft 5 to rotate, thereby mixing the coating industrial medium inside the mixing box 1 through the first stirring rod 6. Several third stirring rods 25 are evenly fixedly installed on the drive shaft 24 inside the water tank 18. Under the action of the third stirring rods 25, the water and cleaning agent inside the water tank 18 can be stirred, thereby ensuring the efficiency of the cleaning water use. A drive motor 28 is fixedly installed on the outer wall of one side of the mounting shell 23. The power output shaft of the drive motor 28 is fixedly connected to the drive shaft 24 through a coupling. At this time, the drive motor 28 can drive the drive shaft 24 to rotate.
[0025] Working Principle: When the mixing tank 1 is in operation, the sealing plate 4 is first removed from the feed inlet 3, and the coating industrial medium is added into the mixing tank 1 through the feed inlet 3. Then, the sealing plate 4 is installed. The drive motor 28 is started, and its power output shaft drives the drive shaft 24 to rotate. The first bevel gear 26 on the drive shaft 24 rotates accordingly. Since the second bevel gear 27 meshes with the first bevel gear 26, the second bevel gear 27 drives the rotating shaft 5 to rotate. The first stirring rod 6 on the rotating shaft 5 performs preliminary mixing of the coating industrial medium in the mixing tank 1. At the same time, the rotating shaft 13 on the mounting bracket 12 on the rotating shaft 5 drives the second stirring rod 14 to rotate, further stirring the mixed medium and improving the mixing efficiency. When the rotating shaft 5 rotates, it drives the support rod 7, the limiting plate 8, the sleeve 9, and the scraper 10 to rotate. The scraper 10 scrapes away the medium adhering to the inner wall of the mixing tank 1, and the return spring 11 ensures the contact quality between the scraper 10 and the inner wall. After mixing is completed, the valve 16 on the discharge pipe 15 is opened to discharge the mixed medium. During cleaning, the pump 20 is started, and the cleaning water in the water tank 18 enters the diversion pipe 21 through the conduit and is sprayed out by the nozzle 22 to spray and clean the inside of the mixing tank 1. The scraper 10 is used to ensure the cleaning quality. When the drive shaft 24 rotates, the third stirring rod 25 on it stirs the water and detergent in the water tank 18, improving the efficiency of cleaning water use.
