Description

Technical Field

[0001] This utility model relates to the field of waterproof coating processing technology, and in particular to a raw material mixing device for waterproof coating processing. Background Technology

[0002] Acrylic waterproof coating is a single-component water-emulsion type waterproof coating made from pure acrylic polymer emulsion as the base material and with the addition of other additives. The waterproof film formed after curing has certain extensibility, elasticity, crack resistance, impermeability, and weather resistance, providing waterproofing, seepage prevention, and protection. The waterproof coating has good temperature adaptability, is easy to apply, and is convenient to repair and maintain.

[0003] The utility model patent with authorization announcement number CN221816026U discloses a mixing and stirring device for water-based waterproof coating raw materials, including a support frame and a mixing tank. A transmission box is welded to the top of the support frame, and a servo motor is fixed to the transmission box by bolts. By starting the servo motor installed on the transmission box, the output end of the servo motor drives the connecting rod to rotate under the action of the pulley and the transmission belt. In turn, the connecting rod drives the transmission rod to rotate, so that the stirring blades at the bottom of the transmission rod mix and stir the water-based waterproof coating raw materials in the mixing tank. By connecting the connecting sleeve at the top of the transmission rod to the bottom of the connecting rod, and then rotating the plum blossom knob inserted on the side of the connecting sleeve, one end of the plum blossom knob is threadedly connected to the threaded groove on the surface of the connecting rod, realizing the detachable installation of the transmission rod and the connecting rod. Then, the two semi-circular split covers are put together, and the two semi-circular split covers and the clearance grooves opened at their centers are used to seal the mixing tank and allow the transmission rod to make room. The above device has the following shortcomings: it is inconvenient to repeatedly disassemble and assemble the transmission rod and the connecting rod each time it is stirred. Utility Model Content

[0004] The purpose of this invention is to provide a raw material mixing device for waterproof coating processing, which facilitates the removal of the transmission rod from the mixing tank and improves mixing efficiency.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a raw material mixing device for waterproof coating processing, comprising a base, a support frame fixed to the base, a mixing tank disposed on the base, and two separate covers slidably connected to the top surface of the mixing tank. The support frame is provided with a drive groove, and a threaded rod is rotatably connected in the drive groove. The threaded rod is threadedly connected to a slide block that slides on the support frame. A first movable frame is fixed to one side of the slide block. A transmission rod is slidably connected to the first movable frame. A connecting plate is fixed to the upper end of the transmission rod, and multiple mixing rods are fixed to the bottom end. A mixing motor for driving the transmission rod to rotate is fixedly installed on the connecting plate. An adjusting motor for driving the threaded rod to rotate is installed on the support frame.

[0006] By adopting the above technical solution, the two separate covers are opened, and the screw rod is rotated by adjusting the motor. The rotation of the screw rod causes the slide and the first movable frame to slide and rise on the support frame. Thus, the transmission rod and stirring rod on the first movable frame slide and rise, allowing the stirring rod to be inserted into or removed from the mixing tank. This facilitates the addition of water to the mixing tank and the removal of the paint, while eliminating the need for manual disassembly. It is more convenient to use and helps to improve the overall mixing efficiency of the paint. The stirring motor on the connecting plate drives the transmission rod and the stirring rod to rotate for mixing.

[0007] A further feature of this invention is that a limiting strip is fixed on the support frame and arranged along the direction of the threaded rod, and the slide block is provided with a limiting groove for the limiting strip to be inserted and slid.

[0008] By adopting the above technical solution, the limiting strip and the limiting groove work together to make the first movable frame rise and fall stably on the support frame.

[0009] A further feature of this invention is that: the transmission rod is inserted and slidably mounted on the first movable frame; the connecting plate is fixed with guide rods located on both sides of the transmission rod; the guide rods on both sides are inserted and slidably mounted on the first movable frame; a telescopic spring sleeved on the guide rods is fixed between the connecting plate and the first movable frame; a rotating shaft is rotatably connected to the first movable frame; and a cam that cooperates with the connecting plate to drive the connecting plate to rise and fall is fixed on the rotating shaft.

[0010] By adopting the above technical solution, when the stirring rod is inserted into the mixing tank and rotates to perform stirring, the cam rotates continuously to lift the connecting plate. In conjunction with the telescopic spring and guide rod, the connecting plate is pulled back close to the first movable frame, thereby driving the connecting plate to reciprocate up and down on the first movable frame. This causes the transmission rod and stirring rod to reciprocate up and down in the mixing tank, generating a more complex vortex in the mixing tank, which is beneficial to improving the uniformity of dye mixing and optimizing stirring efficiency.

[0011] A further feature of this invention is that a drive shaft is rotatably connected to the first movable frame, and pulleys are fixed on both the drive shaft and the rotating shaft. A drive belt is sleeved between the two pulleys, and a drive motor for driving the drive shaft to rotate is fixedly installed on the first movable frame.

[0012] By adopting the above technical solution, the drive motor is started, which drives the drive shaft to rotate. The drive shaft then drives the rotating shaft to rotate via the drive belt, thereby realizing the continuous rotation of the rotating shaft and the cam, which drives the stirring rod to reciprocate up and down inside the mixing tank.

[0013] A further feature of this invention is that the base has a positioning groove located below the transmission rod and a first adjustment cavity located below the positioning groove. A positioning plate slides in the positioning groove, and a plurality of feeding cylinders are installed in the first adjustment cavity. The output end of the feeding cylinder is fixedly connected to the lower part of the positioning plate.

[0014] By adopting the above technical solution, the feeding cylinder drives the positioning plate to rise, and after the positioning plate is moved out of the positioning groove, the mixing drum is pushed onto the positioning plate. The feeding cylinder then drives the positioning plate to descend until the bottom of the positioning plate abuts against the inner wall of the positioning groove, placing the bottom of the mixing drum into the positioning groove. The positioning groove not only positions the positioning plate as it descends, but also restricts the mixing drum, preventing it from moving arbitrarily during mixing. The feeding cylinder can automatically feed the mixing drum into the positioning groove and automatically remove it from the positioning groove, reducing labor and further improving overall work efficiency.

[0015] A further feature of this invention is that a baffle is fixed to one side of the positioning plate.

[0016] By adopting the above technical solution, the baffle positions the mixing tank on the positioning plate, so that the mixing tank is moved to the positioning plate and the opening of the mixing tank is located directly below the mixing rod.

[0017] A further feature of this invention is that a handle is fixed to one side of the mixing tank.

[0018] By adopting the above technical solution, it is easier for staff to push the mixing tank.

[0019] A further feature of this invention is that the base has a second adjustment cavity located below the support frame, a first adjustment shaft and a second adjustment shaft are rotatably connected in the second adjustment cavity, the first adjustment shaft is fixedly connected to the bottom of the support frame, a shifting motor for driving the second adjustment shaft to rotate is fixedly installed in the second adjustment cavity, a transmission belt is sleeved between the first adjustment shaft and the second adjustment shaft, a second movable frame is fixedly installed on the side of the slide away from the first movable frame, a fixed rod is rotatably connected to the bottom of the second movable frame, a scraper is fixed on the fixed rod, and a cleaning motor for driving the fixed rod to rotate is fixedly installed on the second movable frame.

[0020] By adopting the above technical solution, when the slide and the first movable frame rise, and the transmission rod and stirring rod are moved out of the mixing tank, the shifting motor is started. The shifting motor drives the second adjusting shaft to rotate, and then the second adjusting shaft drives the first adjusting shaft to rotate through the transmission belt. Then the support frame rotates to switch the position of the fixed rod and scraper to be above the mixing tank. The adjusting motor is started to drive the threaded rod to rotate, and then the slide and the second movable frame descend, placing the scraper into the mixing tank. The cleaning motor drives the fixed rod and scraper to rotate inside the mixing tank, thereby scraping and cleaning the coating adhering to the inner wall of the mixing tank.

[0021] A further feature of this invention is that the scraper is U-shaped as a whole.

[0022] By adopting the above technical solution, the U-shaped scraper can cooperate with the inner wall of the mixing tank to scrape and clean the inner wall of the mixing tank.

[0023] A further feature of this invention is that two positioning posts are welded to the top surface of the mixing tank, and the two positioning posts correspond one-to-one with the two split covers. A strip-shaped opening is provided on the surface of the split cover corresponding to the positioning post, and the positioning post extends to the inside of the strip-shaped opening.

[0024] By adopting the above technical solution, the two separate covers can be installed and positioned, and the two separate covers can be guided and moved to facilitate the opening and closing of the two separate covers.

[0025] The beneficial effects of this utility model are:

[0026] 1. It can automatically extend the stirring rod into or out of the mixing tank, which facilitates the addition of water and paint from the mixing tank while eliminating the need for manual disassembly. This makes it more convenient to use and helps improve the overall mixing efficiency of the paint.

[0027] 2. When the stirring rod is inserted into the mixing tank and rotates to perform stirring, the cam continues to rotate, lifting the connecting plate. With the help of the telescopic spring and the guide rod, the connecting plate is pulled back close to the first movable frame. This drives the transmission rod and the stirring rod to move up and down repeatedly in the mixing tank, creating a more complex vortex inside the mixing tank. This helps to improve the uniformity of dye mixing and optimize stirring efficiency.

[0028] 3. The positioning groove enables the positioning plate to descend and position itself, while also restricting the mixing drum and preventing it from moving around during mixing. The feeding cylinder can automatically feed the mixing drum into the positioning groove and automatically remove it from the positioning groove, reducing labor and further improving overall work efficiency.

[0029] 4. The shifting motor drives the second adjusting shaft to rotate, which in turn drives the first adjusting shaft to rotate, causing the support frame to rotate and switch the position of the fixed rod and scraper to the top of the mixing tank. The adjusting motor is then started to drive the threaded rod to rotate, which in turn causes the slide and the second movable frame to descend, placing the scraper into the mixing tank. The cleaning motor drives the fixed rod and scraper to rotate inside the mixing tank, scraping off the coating adhering to the inner wall of the mixing tank. Attached Figure Description

[0038] Furthermore, a drive shaft 19 is rotatably connected to the first movable frame 8. Both the drive shaft 19 and the rotating shaft 17 are fixed with pulleys. A drive belt 20 is sleeved between the two pulleys. A drive motor 21 that drives the drive shaft 19 to rotate is fixedly installed on the first movable frame 8.

[0039] Furthermore, the base 1 is provided with a positioning groove 23 located below the transmission rod 9 and a first adjustment cavity 22 located below the positioning groove 23. A positioning plate 24 slides in the positioning groove 23, and a plurality of feeding cylinders 25 are installed in the first adjustment cavity 22. The output end of the feeding cylinder 25 is fixedly connected to the lower part of the positioning plate 24.

[0040] Furthermore, a baffle 26 is fixed to one side of the positioning plate 24.

[0041] Furthermore, a handle 27 is fixed to one side of the mixing tank 3.

[0042] Furthermore, the base 1 is provided with a second adjustment cavity 28 located below the support frame 2. A first adjustment shaft 29 and a second adjustment shaft 30 are rotatably connected in the second adjustment cavity 28. The first adjustment shaft 29 is fixedly connected to the bottom of the support frame 2. A shifting motor 38 that drives the second adjustment shaft 30 to rotate is fixedly installed in the second adjustment cavity 28. A transmission belt 31 is sleeved between the first adjustment shaft 29 and the second adjustment shaft 30. A second movable frame 32 is fixed on the side of the slide 7 away from the first movable frame 8. A fixing rod 33 is rotatably connected to the bottom of the second movable frame 32.

The drive motor 21 drives the drive shaft 19 to rotate, and the drive shaft 19 drives the rotating shaft 17 to rotate through the drive belt 20. This causes the rotating shaft 17 and the cam 18 to rotate continuously. The continuous rotation of the cam 18 lifts the connecting plate 10, and with the help of the telescopic spring 16 and the guide rod 15, it pulls the connecting plate 10 back close to the first movable frame 8, thus driving the connecting plate 10 to reciprocate up and down on the first movable frame 8. This causes the transmission rod 9 and the stirring rod 11 to reciprocate up and down in the mixing tank 3, generating more complex vortices in the mixing tank 3, which is beneficial to improving the uniformity of dye mixing and optimizing the stirring efficiency. After the stirring work is completed, the output end of the feeding cylinder 25 drives the positioning plate 24 to rise, moving the positioning plate 24 out of the positioning groove 23, and also moving the mixing tank 3 out of the positioning groove 23.

[0046] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
