Description

Technical Field

[0001] This utility model relates to the field of mixing technology, specifically to a raw material mixing device for coating material production. Background Technology

[0002] In the production process of coating materials, the mixing of raw materials is a crucial step, as its uniformity and efficiency directly affect the quality and performance of the final coating material. Traditional raw material mixing devices typically only have simple stirring functions; however, these traditional devices have gradually revealed many problems in practical use.

[0003] Firstly, during the raw material addition process, the raw materials often flow from the storage container into the mixing container in a concentrated manner, making it difficult to achieve uniform distribution. This can lead to uneven local concentrations of the raw materials in the initial stage of mixing, thus affecting the overall mixing effect. Different coating material raw materials have different physical and chemical properties, such as pigments of different particle sizes, resins of different viscosities, and various additives. If they cannot enter the mixing container uniformly, they will form local agglomeration or stratification during the mixing process, thereby affecting the color uniformity, coating performance, and other indicators of the final product.

[0004] Secondly, traditional equipment lacks effective solutions for the problem of adhesion to the inner wall of the mixing container. During the mixing process, coating material raw materials tend to adhere to the inner wall of the mixing tank due to their own viscosity or other physicochemical properties, especially at the bottom and middle of the tank. Long-term accumulation of these deposits may affect the mixing quality of subsequent batches, requiring frequent shutdowns for cleaning and significantly reducing production efficiency.

[0005] Therefore, we propose a raw material mixing device for coating material production to solve the problems mentioned above. Utility Model Content

[0006] 1. The technical problem to be solved by the utility model:

[0007] The purpose of this invention is to provide a raw material mixing device for coating material production, so as to solve the problems currently found in the market as mentioned in the background art.

[0008] 2. Technical Solution:

[0009] To achieve the above objectives, the present invention provides the following technical solution: a raw material mixing device for coating material production, comprising a mixing tank, a plurality of raw material storage tanks installed at the upper end of the mixing tank, a valve body installed at the lower end of the raw material storage tanks, and the lower port of the raw material storage tanks located inside the mixing tank, and a diversion component corresponding to the lower port of each raw material storage tank, the diversion component being installed inside the upper end of the raw material storage tank;

[0010] The mixing tank has a central bearing on which a stirring rod is installed, and a transmission component is installed at the upper end of the stirring rod. The stirring rod drives the flow distribution assembly to rotate through the transmission component, and the transmission component is located inside the frame. The frame is fixedly installed inside the upper end of the mixing tank.

[0011] Furthermore, a secondary stirring rod is installed at the lower end of the main stirring rod, and a scraper is installed at the end of the secondary stirring rod located at the bottom, and the scraper is used to scrape off the material adhering to the inner wall of the bottom of the mixing tank.

[0012] The above technical solution enables the main stirring rod to rotate synchronously with the auxiliary stirring rod and scraper rod, thus agitating the material and scraping off the substances adhering to the inner wall.

[0013] Furthermore, the diversion assembly includes a rotating rod with a bearing mounted on the mixing tank, a diversion plate fixedly sleeved in the middle of the rotating rod, and a guide gear installed at the end of the rotating rod inside the frame.

[0014] The above technical solution enables the material to be diverted when the diverting plate rotates forward and backward around the rotating rod.

[0015] Furthermore, the transmission component includes a reciprocating lead screw fixedly connected to the upper end of the stirring main rod. A movable frame is threaded on the outer side of the reciprocating lead screw, and the movable frame and the frame body are in a sliding connection that fits together vertically. A rack is fixed on the side of the movable frame, and the rack is meshed with the guide gear.

[0016] The above technical solution enables the stirring rod to drive the reciprocating screw to rotate, which in turn drives the movable frame to move up and down, thereby driving the guide gear meshing with the rack to rotate.

[0017] Furthermore, an "U"-shaped bracket is slidably installed inside the frame, the bracket is fixedly connected to the movable frame, and a scraping component is fixed at the lower end of the bracket, and the scraping component is distributed vertically at equal intervals.

[0018] The above technical solution allows the support frame to move up and down along with the movable frame.

[0019] Furthermore, the scraper is ring-shaped, and the inner wall thickness of the scraper is less than the outer wall thickness of the scraper. The scraper is used to scrape off the material adhering to the inner wall of the middle part of the mixing tank.

[0020] The above technical solution enables the scraper to scrape off the material adhering to the inner wall when it moves up and down, while also turbulenting the material flow.

[0021] 3. Beneficial effects:

[0022] Compared with the prior art, the raw material mixing device for coating material production of this utility model disperses the raw materials flowing out of the raw material storage tank through a diversion component, so that the raw materials enter the mixing tank more evenly and avoid uneven mixing caused by concentrated flow of raw materials. The specific details are as follows:

[0023] When the motor drives the mixing rod to rotate, it can drive the reciprocating screw to rotate synchronously. After the reciprocating screw rotates, the movable frame with the thread sleeve on the outside of the reciprocating screw moves up and down inside the frame by the contact action between it and the frame. During the movement, the meshing action of the rack and the guide gear drives the flow divider to rotate in both directions. Then, when the valve body is opened and the raw material flows out from the lower port of the raw material storage tank, it will be dispersed by the flow divider. This allows the raw material to enter the mixing tank more evenly and avoids the situation where the raw material flows in concentratedly and causes uneven mixing.

[0024] The main stirring rod stirs the raw materials in the mixing tank through the auxiliary stirring rod, promoting thorough mixing of different raw materials. The scraper on the auxiliary stirring rod removes substances adhering to the bottom inner wall of the mixing tank, preventing raw materials from accumulating and sticking at the bottom, ensuring the cleanliness of the bottom of the mixing tank, and avoiding affecting the subsequent mixing effect. As the movable frame moves up and down, it drives the support and scraper to move up and down synchronously, scraping off the substances adhering to the inner wall of the middle of the mixing tank. During the up and down sliding process, the material is turbulent, further improving the mixing effect. Attached Figure Description

[0034] Please see Figure 1-4A raw material mixing device for coating material production includes a mixing tank 1, with several raw material storage tanks 2 installed at the upper end of the mixing tank 1. A valve body 3 is installed at the lower end of each raw material storage tank 2, and the lower port of each raw material storage tank 2 is located inside the mixing tank 1. A flow-diverting component 6 is correspondingly provided at the lower port of each raw material storage tank 2, and the flow-diverting component 6 is installed inside the upper end of the raw material storage tank 2. A stirring rod 4 is mounted on a bearing in the middle of the mixing tank 1, and a transmission component 7 is installed at the upper end of the stirring rod 4. The stirring rod 4 drives the flow-diverting component 6 to rotate via the transmission component 7. The frame 8 is fixedly installed inside the upper end of the mixing tank 1; the diversion component 6 includes a rotating rod 61 with a bearing mounted on the mixing tank 1, a diversion plate 62 fixedly sleeved in the middle of the rotating rod 61, and a guide gear 63 installed at the end of the rotating rod 61 inside the frame 8; the transmission component 7 includes a reciprocating screw 71 fixedly connected to the upper end of the stirring main rod 4, a movable frame 72 threaded on the outer side of the reciprocating screw 71, and the movable frame 72 and the frame 8 are in a sliding connection of upper and lower fit, and a rack 73 is fixed on the side of the movable frame 72, and the rack 73 and the guide gear 63 are in a meshing connection.

[0035] The motor at the end of the stirring rod 4 is started, which drives the stirring rod 4 to rotate. During the rotation of the stirring rod 4, the reciprocating screw 71 can rotate synchronously. The movable frame 72, which is threaded on the outside of the reciprocating screw 71, moves up and down inside the frame 8 by means of the contact action between it and the frame 8. During the up and down movement of the movable frame 72, the meshing action of the rack 73 and the guide gear 63 drives the flow divider 62 to rotate in both directions. When the valve body 3 is opened and the raw material flows out from the lower port of the raw material storage tank 2, it will be dispersed by the flow divider 62. This allows the raw material to enter the mixing tank 1 more evenly and avoids the situation where the raw material flows in concentratedly and causes uneven mixing.

[0036] A mixing rod 5 is installed at the lower end of the mixing rod 4, and a scraper 51 is installed at the end of the mixing rod 5 at the bottom. The scraper 51 is used to scrape off the material adhering to the inner wall of the bottom of the mixing tank 1. A "U"-shaped bracket 9 is slidably installed inside the frame 8. The bracket 9 is fixed to the movable frame 72, and a scraper 10 is fixed at the lower end of the bracket 9. The scraper 10 is distributed vertically and vertically at equal intervals. The scraper 10 is ring-shaped, and the inner wall thickness of the scraper 10 is less than the outer wall thickness of the scraper 10. The scraper 10 is used to scrape off the material adhering to the inner wall of the middle part of the mixing tank 1.

[0037] The main stirring rod 4 stirs the raw materials in the mixing tank 1 through the auxiliary stirring rod 5, promoting thorough mixing of different raw materials. The scraper 51 on the auxiliary stirring rod 5 scrapes away the substances adhering to the bottom inner wall of the mixing tank 1, preventing the raw materials from accumulating and adhering at the bottom, ensuring the cleanliness of the bottom of the mixing tank 1, and avoiding affecting the subsequent mixing effect. While the movable frame 72 moves up and down, it drives the support 9 and the scraper 10 to move up and down synchronously, scraping away the substances adhering to the inner wall of the middle part of the mixing tank 1. During the up and down sliding process, the material is turbulent, further improving the mixing effect.

[0038] Working principle: When using this raw material mixing device for coating material production, such as Figure 1-4 As shown, the motor at the end of the stirring rod 4 is started. The stirring rod 4 uses the stirring auxiliary rod 5 to stir the raw materials in the mixing tank 1, so as to promote the thorough mixing of different raw materials. The scraper 51 on the stirring auxiliary rod 5 scrapes off the material adhering to the bottom inner wall of the mixing tank 1. At the same time, the meshing action between the rack 73 and the guide gear 63 on the transmission component 7 drives the flow divider 62 to rotate forward and backward. When the valve body 3 is opened, the raw materials flow out from the lower port of the raw material storage tank 2 and are dispersed by the flow divider 62, so that the raw materials enter the mixing tank 1 more evenly and avoid the situation of uneven mixing caused by concentrated flow of raw materials. The movable frame 72 on the transmission component 7 can drive the scraper 10 to slide up and down to scrape the material adhering inside and turbulent the material, further improving the mixing effect.
