Description

Technical Field

[0001] The invention belongs to the technical field of paint manufacturing equipment, and in particular relates to a uniform stirring device for paint manufacturing. Background Art

[0002] In the production process of paint, stirring is the key link to ensure uniform distribution of paint ingredients, stable performance and improve product quality. At present, the commonly used paint stirring device mainly adopts a fixed-axis stirring mechanism to achieve paint mixing by rotating the stirring blades. However, this single rotation method is prone to produce stirring dead angles when dealing with high-viscosity or easy-to-sediment paint, resulting in uneven paint mixing. At the same time, during the stirring process, the inner wall of the stirring chamber is prone to adhere to the paint, resulting in waste of paint and difficulty in cleaning the equipment.

[0003] In addition, when the traditional stirring device is running at high speed, the friction between the stirring blades and the inner wall of the stirring chamber increases, which may cause equipment wear and increased energy consumption; after stirring is completed, there will be paint residue on the inner wall of the stirring chamber. Summary of the invention

[0004] In view of the problems existing in the prior art, the purpose of the present invention is to provide a uniform stirring device for paint manufacturing, which can improve the mixing uniformity of the paint during the stirring process, reduce stirring dead angles, and reduce equipment wear during high-speed operation, while facilitating the cleaning of the stirring device on the inner wall of the stirring bin to meet the actual needs of paint production.

[0005] To achieve the above object, the present invention provides the following technical solutions: A uniform stirring device for coating manufacturing, comprising a stirring chamber for accommodating the coating to be stirred, a driving mechanism being arranged on the top of the stirring chamber, and a linkage assembly being rotatably connected to the inner top of the stirring chamber; The bottom of the linkage assembly is mirror-imaged with a wall scraping assembly; The wall scraping assembly is used to stir the paint in the stirring chamber and clean the paint on the inner wall of the stirring chamber; When the mixing chamber is mixing the paint, the scraper assembly does not fit the inner wall of the mixing chamber. When the scraper assembly cleans the paint on the inner wall of the mixing chamber, the scraper assembly fits the inner wall of the mixing chamber. The bottom of the linkage assembly is rotatably provided with a stirring mechanism, and the stirring mechanism is used to stir the paint in the stirring bin.

[0006] Furthermore, a bin cover is provided on the top of the mixing bin; The driving mechanism comprises a gearbox connected to the top of the bin cover, a motor is arranged on the top of the gearbox, and a driving gear is connected to the output end of the gearbox.

[0007] Furthermore, the linkage assembly includes a linkage disk rotatably connected to the bin cover, and a driven gear is fixedly connected to the top of the linkage disk, and the driven gear cooperates with the driving gear; The bottom of the linkage disk is fixedly connected with an auxiliary gear, and the auxiliary gear is coaxially arranged with the driven gear.

[0008] Further, the stirring mechanism includes a stirring frame rotatably connected to the linkage disk; A linkage gear is sleeved on the top of the stirring frame, and the linkage gear matches the auxiliary gear.

[0009] Furthermore, three connecting rods are arranged at the bottom of the stirring frame, and the three connecting rods are arranged at equal intervals, and each connecting rod is connected to a stirring blade.

[0010] Furthermore, the number of the driving mechanisms is set to two, and the two driving mechanisms are symmetrically arranged on the top of the mixing chamber.

[0011] Furthermore, the wall scraping assembly includes a base connected to the linkage disk, one side of the base is rotatably connected to a scraper, and one side of the base and the scraper is symmetrically rotatably connected to a hydraulic rod.

[0012] Furthermore, the number of the hydraulic rods is set to two.

[0013] Furthermore, a protective rubber strip is provided on the free end of the scraper.

[0014] Compared with the prior art, the present invention has the following beneficial effects: First, by designing a stirring mechanism that can rotate and revolve, the problem of traditional fixed-axis stirring devices easily generating stirring dead angles when handling high-viscosity or easy-to-sediment coatings is solved. While the stirring mechanism makes a circular motion around the central axis in the stirring chamber, the stirring blades also rotate around their own axis, ensuring the comprehensive mixing of the coating in the stirring chamber, improving the uniformity and efficiency of stirring, and meeting the needs of high-quality coating production.

[0015] Secondly, the present invention cleverly solves the problems of equipment wear and increased energy consumption during the mixing process by installing an adjustable scraper assembly on the linkage disk. When the mixing speed is high, the resistance of the scraper increases, the hydraulic rod is compressed, and the scraper automatically separates from the inner wall of the mixing chamber, reducing friction and equipment wear, and reducing energy consumption; when the mixing speed is reduced, the scraper fits with the inner wall of the mixing chamber under the action of the hydraulic rod, which can effectively clean the residual paint on the inner wall, reduce paint waste, facilitate equipment cleaning, and improve production efficiency.

[0016] Thirdly, through the detailed design and data support of the relationship between the scraper resistance and the hydraulic rod compression, the scraper position can be adjusted intelligently. According to the change of the linkage disk speed, the scraper can automatically adjust the contact state with the inner wall of the mixing chamber, which not only ensures efficient mixing effect, but also extends the service life of the equipment, reduces maintenance costs, and improves the stability of equipment operation.

[0017] In summary, the present invention effectively solves the problems of uneven stirring, equipment wear, high energy consumption and difficulty in cleaning existing in traditional stirring devices, and provides a uniform stirring device for paint manufacturing with a reasonable structure and complete functions, which meets the actual needs of paint production and has significant economic and social benefits.

[0037] The working principle of the present invention is: When in use, the paint to be stirred is put into the stirring chamber 1. During the stirring process, the motor 21 drives the driving gear 23 to rotate through the gearbox 22. The driving gear 23 cooperates with the driven gear 32. With the rotation of the driving gear 23, the driven gear 32, the linkage plate 31 and the auxiliary gear 33 will rotate synchronously. When the linkage disk 31 rotates, it will drive the stirring mechanism 4 to make a circular motion around the central axis of the stirring chamber 1 inside the stirring chamber 1; The auxiliary gear 33 is linked with the gear 42. When the auxiliary gear 33 rotates, it drives the stirring frame 41 and the stirring blade 43 to make a circular motion around the central axis of the linkage gear 42. In summary, when the stirring mechanism 4 is stirring the paint in the stirring chamber 1, the stirring mechanism 4 rotates while making a circular motion inside the stirring chamber 1; When the linkage disk 31 rotates inside the mixing chamber 1, it will drive the scraper assembly 5 installed on the linkage disk 31 to rotate. When the rotation speed is high, the resistance of the scraper 52 will increase. As the resistance increases, the hydraulic rod 53 will be compressed, and then the scraper 52 will separate from the inner wall of the mixing chamber 1, thereby reducing the friction between the scraper 52 and the inner wall of the mixing chamber 1, and then the scraper 52 will stir the paint in the mixing chamber 1. When it is necessary to discharge the mixed paint in the mixing chamber 1, the rotation speed of the linkage disk 31 will become lower. As the rotation speed decreases, the resistance encountered by the scraper 52 will decrease. At this time, under the action of the hydraulic rod 53, the scraper 52 is made to fit the inner wall of the mixing chamber 1, so that the scraper 52 can scrape off the paint on the inner wall of the mixing chamber 1 during the rotation process, thereby reducing the residual paint in the mixing chamber 1.

[0038] The above is only a preferred embodiment of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be considered as the protection scope of the present invention.
