Abstract
Description
Technical Field
[0001] This utility model belongs to the field of waterproof coating production technology, and in particular relates to a polyurethane waterproof coating mixing device. Background Technology
[0002] Waterproof coatings are viscous, liquid polymer synthetic materials that exist without a fixed shape at room temperature. After application, they cure on the substrate surface through solvent evaporation, water evaporation, or reaction, forming a tough, waterproof film. The production of waterproof coatings involves using a waterproof composite as a base material, mixed with inorganic fillers, crosslinking agents, catalysts, toughening agents, defoamers, and other chemical additives. A stirring device is required during mixing.
[0003] Existing mixing devices often use a drive component to rotate the mixing frame, thereby achieving the purpose of mixing the materials in the mixing tank. However, this method of mixing is relatively simple, resulting in poor mixing effect. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides a polyurethane waterproof coating agent mixing device.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0006] This utility model relates to a polyurethane waterproof coating mixing device, comprising a mixing tank, a motor fixedly connected to the top of the mixing tank, the output end of the motor being rotatably connected inside the mixing tank, a rotating rod fixedly connected to the output end of the motor, a fixed frame fixedly connected to the outer wall of the rotating rod, a first gear fixedly connected to the outer wall of the rotating rod, two fixed frames being provided, a connecting rod being rotatably connected to one side of the two fixed frames that are close to each other, the top end of the connecting rod penetrating through the top end of the upper connecting rod and extending therefrom, a second gear fixedly connected to the top end of the connecting rod, the second gear meshing with the first gear, a horizontal bar fixedly connected to the outer wall of the connecting rod, and a vertical bar fixedly connected to the outer wall of the horizontal bar.
[0007] The above technical solution allows the motor to drive the rotating rod to rotate, which in turn drives the fixed frame to rotate, and the fixed frame to drive the connecting rod to rotate, thus causing the connecting rod to rotate around the rotating rod.
[0008] As a further improvement to the above solution, the motor is located at the central axis of the mixing tank, two connecting rods are provided, the two connecting rods are symmetrically arranged with respect to the center of the fixing frame, and two second gears are provided, the two second gears are symmetrically arranged with respect to the first gear.
[0009] As a further improvement to the above solution, sleeves are fixedly connected to both ends of the fixing frame, and springs are fixedly connected inside the sleeves. A limiting piece is fixedly connected to the end of the spring away from the fixing frame. The limiting piece is slidably connected inside the sleeve, and a limiting rod is fixedly connected to the side of the limiting piece away from the spring.
[0010] The above technical solution effectively limits the limit rod by using the limiting plate, preventing the limit rod from detaching from the sleeve.
[0011] As a further improvement to the above solution, the diameter of the limiting piece is larger than the diameter of the sleeve opening, and the diameter of the limiting rod is smaller than the diameter of the limiting piece opening.
[0012] As a further improvement to the above solution, the end of the limiting rod away from the limiting plate passes through the side wall of the sleeve and extends therein, and a scraper is fixedly connected to the end of the limiting rod away from the limiting plate. The side of the scraper away from the limiting rod contacts the inner wall of the mixing tank.
[0013] The above technical solution uses a limiting rod to drive the scraper to rotate, thereby cleaning the inner wall of the mixing tank.
[0014] As a further improvement to the above solution, the top of the mixing tank is connected to a feed inlet, the bottom of the mixing tank is connected to a discharge outlet, a fixing ring is fixedly connected to the outer wall of the mixing tank, and a support column is fixedly connected to the bottom of the fixing ring.
[0015] As a further improvement to the above solution, the discharge port is located at the bottom center axis of the mixing tank, and three support columns are provided, which are symmetrically arranged with respect to the center of the mixing tank.
[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0017] This invention utilizes a motor to drive a rotating rod, which in turn drives a fixed frame to rotate. The fixed frame then drives a first gear to rotate, which in turn drives a connecting rod to rotate around the rotating rod. The connecting rod drives a second gear to rotate, which in turn drives a horizontal bar to rotate. The horizontal bar then drives a vertical bar to rotate. The rotation of the rotating rod via the first gear allows the connecting rod to rotate on its own axis while rotating around the rotating rod. The simultaneous use of horizontal and vertical bars increases the mixing range, thus enabling better mixing of the materials in the mixing tank.
[0018] When the connecting rod rotates, it drives the sleeve to rotate. The sleeve drives the spring, the spring drives the limiting plate, the limiting plate drives the limiting rod, and the limiting rod drives the scraper to rotate along the inner wall of the mixing tank. At the same time, the spring force will make the scraper stick tightly to the inner wall of the mixing tank, thereby effectively cleaning the inner wall of the mixing tank and preventing uneven mixing caused by material adhering to the inner wall of the mixing tank.

[0028] Please see Figure 1-5As shown, this utility model is a polyurethane waterproof coating mixing device, including a mixing tank 1. A motor 2 is fixedly connected to the top of the mixing tank 1. The output end of the motor 2 is rotatably connected inside the mixing tank 1. A rotating rod 3 is fixedly connected to the output end of the motor 2. A fixing frame 4 is fixedly connected to the outer wall of the rotating rod 3. A first gear 5 is fixedly connected to the outer wall of the rotating rod 3. There are two fixing frames 4. A connecting rod 6 is rotatably connected to one side of the two fixing frames 4 that are close to each other. The top end of the connecting rod 6 passes through the top end of the upper connecting rod 6 and extends therefrom. A second gear 7 is fixedly connected to the top end of the connecting rod 6. The second gear 7 meshes with the first gear 5. A horizontal bar 8 is fixedly connected to the outer wall of the connecting rod 6. A vertical bar 9 is fixedly connected to the outer wall of the horizontal bar 8.
[0029] The motor 2 is located at the central axis of the mixing tank 1. There are two connecting rods 6, which are symmetrically arranged around the center of the fixing frame 4. There are two second gears 7, which are symmetrically arranged around the first gear 5.
[0030] Both ends of the fixed frame 4 are fixedly connected to sleeves 10. A spring 11 is fixedly connected inside the sleeve 10. A limit piece 12 is fixedly connected to the end of the spring 11 away from the fixed frame 4. The limit piece 12 is slidably connected inside the sleeve 10. A limit rod 13 is fixedly connected to the side of the limit piece 12 away from the spring 11.
[0031] The diameter of the limiting piece 12 is larger than the opening diameter of the sleeve 10, and the diameter of the limiting rod 13 is smaller than the opening diameter of the limiting piece 12.
[0032] The end of the limiting rod 13 away from the limiting plate 12 passes through the side wall of the sleeve 10 and extends therein. The end of the limiting rod 13 away from the limiting plate 12 is fixedly connected to a scraper 14. The side of the scraper 14 away from the limiting rod 13 contacts the inner wall of the mixing tank 1.
[0033] The top of the mixing tank 1 is connected to a feed inlet 15, the bottom of the mixing tank 1 is connected to a discharge outlet 16, a fixing ring 17 is fixedly connected to the outer wall of the mixing tank 1, and a support column 18 is fixedly connected to the bottom of the fixing ring 17.
[0034] The discharge port 16 is located at the bottom center axis of the mixing tank 1, and three support columns 18 are provided, which are symmetrically arranged with respect to the center of the mixing tank 1.
[0035] A specific application of this embodiment is as follows: During use, material is added through the feed inlet 15, and then the motor 2 is started. The motor 2 drives the rotating rod 3 to rotate, which in turn drives the fixed frame 4 to rotate. The fixed frame 4 drives the first gear 5 to rotate, which in turn drives the connecting rod 6 to rotate around the rotating rod 3. The connecting rod 6 then drives the second gear 7 to rotate, which in turn drives the horizontal bar 8 to rotate. The horizontal bar 8 then drives the vertical bar 9 to rotate. Because the first gear 5 drives the rotating rod 3 to rotate, the connecting rod 6 can rotate on its own axis while rotating around the rotating rod 3. Setting up horizontal bar 8 and vertical bar 9 can increase the mixing range, thereby better mixing the materials in mixing tank 1. When connecting rod 6 rotates, it will drive sleeve 10 to rotate. Sleeve 10 drives spring 11, spring 11 drives limiting plate 12, limiting plate 12 drives limiting rod 13, limiting rod 13 drives scraper 14 to rotate along the inner wall of mixing tank 1. At the same time, the elasticity of spring 11 will make scraper 14 tightly adhere to the inner wall of mixing tank 1, thereby effectively cleaning the inner wall of mixing tank 1 and preventing uneven mixing caused by material adhering to the inner wall of mixing tank 1.
