Description
Technical Field
[0001] The utility model relates to the technical field of paint defoaming, in particular to a defoaming device for water-based paint production. Background Art
[0002] Any paint that uses water as a solvent or dispersion medium can be called a water-based paint. Water-based paint has excellent non-stickiness and durability. Water-based paint uses water as a solvent, saving a lot of resources. Water-based paint eliminates the risk of fire during construction and reduces air pollution. Water-based paint only uses a small amount of low-toxic alcohol ether organic solvents, which improves the working environment conditions.
[0003] A large number of bubbles may be generated inside the water-based paint during production, and these bubbles can be eliminated by a defoaming agent. When defoaming the existing water-based paint, the defoaming agent is generally stirred to make full contact with the paint. For example, a Chinese patent with publication number CN218011208U discloses a defoamer for water-based paint production, including a cylinder, a vibration component is arranged inside the cylinder, and a swing component is arranged at the speed of the vibration component. The vibration component includes a motor, the motor is fixedly connected to the outer wall of the lower end of the cylinder, the output end of the motor is fixedly connected to a rotating shaft, the rotating shaft is rotatably connected to the bottom center of the cylinder, the upper end of the rotating shaft extends to the inside of the cylinder and is fixedly connected to a turntable, and a plurality of slide grooves are opened in a ring shape on the upper surface of the turntable.
[0004] Although the defoamer speeds up the dispersion and reaction speed of the defoamer, in the early stage of defoamer dispersion, the production of water-based paint will still produce certain bubbles. The defoaming method only through the reaction of the defoamer is relatively simple and lacks physical defoaming means.

DETAILED DESCRIPTION
[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0018] Example 1
[0019] Reference Figure 1 , 2 , which is the first embodiment of the utility model, and this embodiment provides a defoaming device for water-based paint production, including a cylinder 1, the top of the cylinder 1 is coaxially rotatably sleeved with a transmission shaft 4, the top of the transmission shaft 4 is fixedly connected to an intermittent transmission component 3, the intermittent transmission component 3 is fixedly connected to the output shaft of a servo motor 2, the servo motor 2 is fixedly installed on one side of the top of the cylinder 1, the bottom end of the transmission shaft 4 is coaxially slidably clamped with a rotating column 7, the rotating column 7 is rotatably sleeved in the cylinder 1, one side of the rotating column 7 is slidably clamped with a sliding column 10, the sliding column 10 is fixedly connected to an inner wall of one side of the cylinder 1, the bottom end of the rotating column 7 is coaxially rotatably connected to a connecting ring 8, the bottom end of the connecting ring 8 is fixedly connected to one end of a spring 9, the other end of the spring 9 is fixedly connected to the bottom wall of the cylinder 1, the bottom end of the rotating column 7 is coaxially fixedly connected to one end of a rotating shaft 5, the rotating shaft 5 is slidably sleeved with the bottom of the cylinder 1 and the other end of the rotating shaft 5 is coaxially fixedly connected to a wire mesh demister 6.
[0020] The cylinder 1 is fixedly installed in the water-based paint tank. When defoaming is working, the servo motor 2 works to drive the intermittent transmission component 3 to rotate, and the transmission component 3 drives the transmission shaft 4 to rotate. The bottom end of the transmission shaft 4 is fixedly connected to the quadrangular prism, and the quadrangular prism is slidably engaged with the rotating column 7, thereby driving the rotating column 7 to rotate synchronously. When the rotating column 7 rotates, the sliding column 10 slides along the arc groove 72. Since the sliding column 10 is fixedly installed on the inner wall of the cylinder 1, the rotating column 7 is pressed down while rotating. The rotating column 7 drives the rotating shaft 5 fixed at the bottom end to move downward, and the rotating shaft 5 drives the wire mesh demister 6 fixed at the bottom end to move downward. The wire mesh demister 6 is immersed in the water-based paint to To perform the defoaming operation, when the rotating column 7 rotates to the position where the sliding column 10 slides out of the arc groove 72, that is, the sliding column 10 is located in the vertical groove 71, the rotating column 7 is lifted under the elastic force of the spring 9, and the sliding column 10 slides in the vertical groove 71. After the rotating column 7 is lifted, the wire mesh demister 6 is lifted synchronously. After the wire mesh demister 6 is lifted, the water-based paint is defoamed again. After the wire mesh demister 6 is separated from the liquid surface of the water-based paint, the elastic force of the rapid lifting causes the water-based paint in the wire mesh demister 6 to be thrown out. The wire mesh demister 6 defoams the water-based paint in two directions of descending and lifting, thereby realizing the function of physical defoaming and ensuring the defoaming effect.
[0021] Example 2
[0022] Reference Figure 1-3 , which is the second embodiment of the utility model, and this embodiment is based on the previous embodiment. Specifically, the intermittent transmission assembly 3 includes a turntable 31, a rotating connecting rod 32, a cylindrical pin 33, and a transmission plate 34. The bottom end of the turntable 31 is coaxially fixedly connected to the output shaft of the servo motor 2, the top end of the turntable 31 is fixedly connected to one side of the rotating connecting rod 32, and the bottom end of the other side of the rotating connecting rod 32 is fixedly connected to the cylindrical pin 33. The outer wall of the turntable 31 is slidably in contact with the transmission plate 34, and the transmission plate 34 is fixedly connected to the top of the transmission shaft 4.
[0023] Furthermore, the length of the rotating connecting rod 32 is greater than the radius of the rotating disk 31 .
[0024] Furthermore, a plurality of crescent openings 341 are provided on the circumferential side of the transmission disk 34, and four crescent openings 341 are evenly distributed around the circumference. The crescent openings 341 are in sliding contact with the outer wall of the turntable 31, and a toggle opening 342 is provided between two adjacent crescent openings 341. The toggle opening 342 is sleeved and cooperated with the cylindrical pin 33. The setting of the crescent openings 341 in sliding contact with the outer wall of the turntable 31 limits the turntable 31 to prevent the turntable 31 from rotating on its own.
[0025] During the defoaming operation, the servo motor 2 works, driving the turntable 31 of the intermittent transmission assembly 3 to rotate, and the turntable 31 synchronously drives the rotating connecting rod 32 to rotate in a circle, and the rotating connecting rod 32 drives the cylindrical pin 33 installed at the end to rotate in a circle synchronously. After the cylindrical pin 33 rotates to the position of the toggle mouth 342, under the continuous rotation of the circular pin 33, the toggle mouth 342 cooperates to toggle the transmission disc 34 to rotate 90 degrees, and the transmission disc 34 drives the transmission shaft 4 fixed at the bottom to rotate.
[0026] Specifically, the arc-shaped outer wall of the rotating column 7 is provided with a plurality of vertical grooves 71, four of which are evenly distributed around the circumference, and an arc-shaped groove 72 is provided between two adjacent vertical grooves 71, one end of the arc-shaped groove 72 is connected to the top end of one vertical groove 71, and the other end of the arc-shaped groove 72 is connected to the bottom end of the other vertical groove 71, and the sliding column 10 is slidably engaged with the vertical groove 71 and the arc-shaped groove 72 respectively.
[0027] The bottom end of the transmission shaft 4 is fixedly connected to the quadrangular prism, and the quadrangular prism is slidably engaged with the rotating column 7, thereby driving the rotating column 7 to rotate synchronously. When the rotating column 7 rotates, the sliding column 10 slides along the arc groove 72. Since the sliding column 10 is fixedly mounted on the inner wall of the cylinder body 1, the rotating column 7 is pressed down while rotating, and the rotating column 7 drives the rotating shaft 5 fixed to the bottom end to move downward, and the rotating shaft 5 drives the wire mesh demister 6 fixed to the bottom end to move downward, and the wire mesh demister 6 is immersed in the water-based paint to defoam the water-based paint. When the rotating column 7 rotates to the position where the sliding column 10 slides out of the arc groove 72, that is, the sliding column 10 is located in the vertical groove 71, the elastic force of the spring 9 drives the rotating column 7 to be lifted, and the sliding column 10 slides in the vertical groove 71. After the rotating column 7 is lifted, it drives the wire mesh demister 6 to be lifted synchronously. After the wire mesh demister 6 is lifted, the water-based paint is defoamed again.
[0028] Furthermore, the vertical groove 71 is arranged correspondingly to the crescent opening 341. The corresponding arrangement enables the arc groove 72 to be arranged correspondingly to the toggle opening 342 when the rotating column 7 is lifted, and the cylindrical pin 33 is in a position that does not cooperate with the toggle opening 342, thereby ensuring the lifting of the rotating column 7.
[0029] Example 3
[0030] Reference Figure 1-3, which is the third embodiment of the utility model. This embodiment is based on the above two embodiments. When in use, the cylinder 1 is fixedly installed in the water-based paint tank. When defoaming is working, the servo motor 2 works to drive the turntable 31 of the intermittent transmission component 3 to rotate, and the turntable 31 synchronously drives the rotating connecting rod 32 to rotate in a circle. The rotating connecting rod 32 drives the cylindrical pin 33 installed at the end to rotate synchronously in a circle. After the cylindrical pin 33 rotates to the position of the toggle port 342, the toggle port 342 is used to toggle the transmission plate 34 to rotate 90 degrees under the continuous rotation of the circumferential pin 33. The transmission plate 34 drives the transmission shaft 4 fixed at the bottom end to rotate. The bottom end of the transmission shaft 4 is fixedly connected to a quadrangular prism, and the quadrangular prism is slidably engaged with the rotating column 7, thereby driving the rotating column 7 to rotate synchronously. When the rotating column 7 rotates, the sliding column 10 slides along the arc groove 72. Since the sliding column 10 is fixedly installed on the inner wall of the cylinder 1, the rotating When the column 7 rotates, it realizes downward movement, and the rotating column 7 drives the rotating shaft 5 fixed at the bottom end to move downward, and the rotating shaft 5 drives the wire mesh demister 6 fixed at the bottom end to move downward, and the wire mesh demister 6 is immersed in the water-based paint to defoam the water-based paint. When the rotating column 7 rotates to the position where the sliding column 10 slides out of the arc groove 72, that is, the sliding column 10 is located at the vertical groove 71, the elastic force of the spring 9 drives the rotating column 7 to be lifted, and the sliding column 10 slides in the vertical groove 71. After the rotating column 7 is lifted, it drives the wire mesh demister 6 to be lifted synchronously. After the wire mesh demister 6 is lifted, the water-based paint is defoamed again. After the wire mesh demister 6 is separated from the liquid surface of the water-based paint, the elastic force of the rapid lifting causes the water-based paint in the wire mesh demister 6 to be thrown out. The wire mesh demister 6 defoams the water-based paint in two directions of descending and lifting, thereby realizing the function of physical defoaming and ensuring the defoaming effect.
