Description

Technical Field

[0001] This utility model belongs to the field of paint mixing technology, specifically a road marking paint mixing device. Background Technology

[0002] Road marking paint is a functional coating specifically designed for painting traffic markings on road surfaces. It combines high visibility, abrasion resistance, weather resistance, adhesion, and environmental friendliness to ensure that the markings can maintain their vibrant colors, good reflectivity, and structural integrity for a long time under various climatic conditions and traffic loads, thereby achieving traffic safety functions such as indication, warning, separation, and guidance.

[0003] In existing road marking paint mixing devices, most use a stirring rod to directly stir the paint. When the paint viscosity is high, the paint at the edge of the mixing tank is prone to uneven mixing. When the paint is not fully mixed, it will lead to uneven distribution of the pigment in the painted markings, resulting in uneven color depth and poor nighttime reflectivity. Furthermore, if the air is not fully vented during the stirring process, air bubbles or micropores are easily left in the paint film, which can cause surface peeling, flaking, and reduced wear resistance. Therefore, this utility model provides a road marking paint mixing device. Utility Model Content

[0004] To address the shortcomings of existing technologies and solve the problem that most road marking paint mixing devices use a stirring rod to directly stir the paint, which can lead to uneven mixing at the edges of the mixing tank when the paint viscosity is high, resulting in uneven pigment distribution, inconsistent color depth, and poor nighttime reflectivity, this invention proposes a road marking paint mixing device.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a road marking paint mixing device of this utility model includes a base, a support seat fixedly connected to the top of the base, a mixing tank fixedly connected to the top of the support seat, and a mixing mechanism provided on the top of the mixing tank. The mixing mechanism includes a sealing cover fixedly connected to the top of the mixing tank, a hollow rod rotatably connected to the top of the sealing cover, two stirring discs fixedly connected to the surface of the hollow rod, a rotating rod rotatably connected to the inside of the hollow rod, a scraper fixedly connected to the bottom of the rotating rod, the side of the scraper slidingly connected to the inner wall of the mixing tank, and multiple stirring blades fixedly connected at equal intervals on the side of the scraper away from the mixing tank. A fixed cylinder is fixedly connected to the top of the sealing cover. A defoaming mechanism is provided on the top side of the base away from the support.

[0006] Preferably, a driving bevel gear is rotatably connected to the inner top of the fixed cylinder, and two driven bevel gears are symmetrically rotatably connected to the middle of the fixed cylinder. Both driven bevel gears are meshed with the driving bevel gear. A driven bevel gear is rotatably connected to the inner bottom of the fixed cylinder. Both driven bevel gears are meshed with the driven bevel gear. The top end of the hollow rod passes through the sealing cover and is fixedly connected to the driven bevel gear. The top end of the rotating rod passes through the driven bevel gear and is rotatably connected to the driven bevel gear. The rotating rod passes through the top end of the driven bevel gear and is fixedly connected to the driving bevel gear.

[0007] Preferably, the scraper is C-shaped.

[0008] Preferably, a motor is fixedly installed at the top of the fixed cylinder, the output shaft of the motor passes through the fixed cylinder and is fixedly connected to the drive bevel gear, and a discharge valve is fixedly connected to the bottom of the mixing tank.

[0009] Preferably, the defoaming mechanism includes a vacuum pump fixedly installed on the top of the base on the side away from the support seat. The input end of the vacuum pump is fixedly connected to a vacuum tube, and the end of the vacuum tube away from the vacuum pump is fixedly connected to a sealing cover. The output end of the vacuum pump is fixedly connected to an exhaust pipe, a pressure gauge is fixedly installed on the exhaust pipe, and a vacuum valve is provided on the exhaust pipe.

[0010] Preferably, a viscometer is fixedly installed on the top of the sealing cover, a water inlet valve is fixedly connected to the top of the sealing cover, and a sealed feed inlet is provided on the top of the sealing cover.

[0011] Preferably, the mixing tank is equipped with a control panel, which is electrically connected to a motor, a vacuum pump, a pressure gauge, and a viscometer.

[0012] The beneficial effects of this utility model are as follows: 1. The road marking paint mixing device of this utility model utilizes the effect of a stirring disc and stirring blades. The toothed structure on the surface of the stirring disc can directly drive the middle part of the paint inside the mixing tank to rotate rapidly. During the movement, the scraper further drives the internal stirring blades to rotate, so that the paint in the edge area of ​​the mixing tank is fully stirred. The scraper also has the function of continuously scraping off the paint adhering to the inner wall of the mixing tank, which can effectively prevent the paint from sticking to the inner wall of the mixing tank. Under the layered stirring action of the stirring disc and stirring blades, the paint forms multi-directional flow shearing in the upper and lower and left and right directions inside the mixing tank, which significantly improves the mixing uniformity.

[0013] 2. The road marking paint mixing device of this utility model, through the setting of an active bevel gear and a driven bevel gear II, the rotation direction of the driven bevel gear II is completely opposite to that of the active bevel gear. The hollow rod then drives the stirring plate to rotate clockwise or counterclockwise, and the hollow rod rotates in the opposite direction, so that the stirring plate and the stirring blade work simultaneously under different directions, forming a shear flow field that crosses up and down and left and right. The stirring plate is responsible for the large-scale overall tumbling of the paint in the middle of the tank, while the stirring blade produces fine local stirring at the edge of the tank wall. The synergistic effect of the two in opposite directions can significantly improve the mixing uniformity of the paint.

[0014] 3. The road marking paint mixing device of this utility model, through the setting of a vacuum pump and a viscometer, after the vacuum pump is started, uses a vacuum tube to extract the air inside the mixing tank to form a negative pressure environment. The formation of negative pressure causes dissolved gases and suspended bubbles in the paint to escape rapidly, thereby achieving efficient defoaming and significantly improving the uniformity and density of the paint. The viscometer can monitor the viscosity change of the paint in real time. Through precise control of viscosity, it can prevent the increase of stirring resistance caused by excessive viscosity, and also avoid insufficient fluidity caused by excessively low viscosity.

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] like Figures 1 to 5 As shown, this utility model provides a technical solution: a road marking paint mixing device, including a base 1, a support seat 2 fixedly connected to the top of the base 1, a mixing tank 3 fixedly connected to the top of the support seat 2, a mixing mechanism 4 provided on the top of the mixing tank 3, the mixing mechanism 4 including a sealing cover 41 fixedly connected to the top of the mixing tank 3, a hollow rod 42 rotatably connected to the top of the sealing cover 41, two stirring discs 43 fixedly connected to the surface of the hollow rod 42, a rotating rod 44 rotatably connected to the inside of the hollow rod 42, a scraper 45 fixedly connected to the bottom of the rotating rod 44, the side of the scraper 45 slidingly connected to the inner wall of the mixing tank 3, a plurality of stirring blades 46 fixedly connected at equal intervals on the side of the scraper 45 away from the mixing tank 3, a fixed cylinder 47 fixedly connected to the top of the sealing cover 41, and a defoaming mechanism 5 provided on the top of the base 1 away from the support seat 2.

[0019] Through the above technical solution, the hollow rod 42 drives the stirring disc 43 to rotate synchronously when rotating. The toothed structure on the surface of the stirring disc 43 can directly drive the middle part of the paint inside the mixing tank 3 to rotate rapidly, achieving preliminary mixing. The rotation of the rotating rod 44 will drive the scraper 45 at its bottom to rotate together. During the movement, the scraper 45 further drives the internal stirring blades 46 to rotate, so that the paint in the edge area of ​​the mixing tank 3 is fully stirred. The scraper 45 also has the function of continuously scraping off the paint adhering to the inner wall of the mixing tank 3, which can effectively prevent the paint from adhering to the inner wall of the mixing tank 3, avoiding secondary pollution or cleaning difficulties caused by residues. Under the layered stirring action of the stirring disc 43 and the stirring blades 46, the paint forms a multi-directional flow and shearing in the mixing tank 3, significantly improving the mixing uniformity. The multi-layered cross stirring method can effectively prevent uneven pigment distribution and avoid quality defects such as uneven color depth and reduced reflectivity at night. At the same time, Uniform mixing can also eliminate local stress concentration, reducing the risk of cracks, peeling, or flaking of the paint film after curing, thereby significantly extending the service life of road markings and improving their weather resistance. In addition, the continuous scraping action of the scraper 45 can promptly remove the small paint droplets remaining on the tank wall after each cycle, ensuring that the inside of the tank always maintains a clean working environment, further improving the stability and repeatability of the subsequent mixing process. Under the premise of ensuring that the paint is fully mixed, it can minimize the occurrence of quality defects and ensure the color consistency, nighttime visibility, and long-term durability of road markings.

[0020] Specifically, such as Figure 3 as well as Figure 4As shown, a driving bevel gear 48 is rotatably connected to the inner top of the fixed cylinder 47. Two driven bevel gears 49 are symmetrically rotatably connected to the middle of the fixed cylinder 47, and both driven bevel gears 49 are meshed with the driving bevel gear 48. A driven bevel gear 410 is rotatably connected to the inner bottom of the fixed cylinder 47, and both driven bevel gears 49 are meshed with the driven bevel gear 410. The top end of the hollow rod 42 passes through the sealing cover 41 and is fixedly connected to the driven bevel gear 410. The top end of the rotating rod 44 passes through the driven bevel gear 410 and is rotatably connected to the driven bevel gear 410. The rotating rod 44 passes through the top end of the driven bevel gear 410 and is fixedly connected to the driving bevel gear 48. The scraper 45 is C-shaped. A motor 411 is fixedly installed on the top of the fixed cylinder 47. The output shaft of the motor 411 passes through the fixed cylinder 47 and is fixedly connected to the driving bevel gear 48. A discharge valve 412 is fixedly connected to the bottom of the mixing tank 3.

[0021] Through the above technical solution, when the motor 411 starts, it drives the active bevel gear 48 to rotate. Simultaneously, the active bevel gear 48, through meshing, drives the driven bevel gears 49 on both sides to rotate together, thereby causing the driven bevel gear 410 to rotate as well. It is worth noting that the rotation direction of the driven bevel gear 410 is completely opposite to that of the active bevel gear 48. This reverse transmission enables bidirectional power distribution in the mechanical system. While the active bevel gear 48 rotates and drives the hollow rod 42, the hollow rod 42 in turn drives the stirring disc 43 to rotate clockwise or counterclockwise. Since the driven bevel gear 410 rotates in the opposite direction to the active bevel gear 48, it synchronously causes the hollow rod 42 to rotate in the opposite direction, thus causing the scraper 45 and the stirring blade 4... 6 also rotates in the opposite direction to the mixing plate 43, so that the mixing plate 43 and the mixing blade 46 work simultaneously under different directions, forming a cross-flow shear field that runs vertically and horizontally. The mixing plate 43 is responsible for a large-scale overall tumbling of the paint in the middle of the tank, while the mixing blade 46 produces fine local stirring at the edge of the tank wall. The synergistic effect of the two in opposite directions can significantly improve the mixing uniformity of the paint, avoid quality problems such as color differences and nighttime reflection attenuation caused by pigment aggregation or uneven viscosity. The stirring in different directions can disperse shear stress, prevent the paint film from cracking, peeling or flaking after curing, and the load distribution of opposite directions can balance the wear of gears and bearings, reduce the risk of unilateral overload, and achieve the effect of extending the service life of the equipment.

[0022] Specifically, such as Figure 1As shown in Figure 5, the defoaming mechanism 5 includes a vacuum pump 51 fixedly installed on the top of the base 1 away from the support 2. The input end of the vacuum pump 51 is fixedly connected to a vacuum tube 52. The end of the vacuum tube 52 away from the vacuum pump 51 is fixedly connected to the sealing cover 41. The output end of the vacuum pump 51 is fixedly connected to an exhaust pipe 53. A pressure gauge body 54 is fixedly installed on the exhaust pipe 53. A vacuum valve 55 is provided on the exhaust pipe 53. A viscometer 56 is fixedly installed on the top of the sealing cover 41. A water inlet valve 57 is fixedly connected to the top of the sealing cover 41. A sealed feed inlet 58 is provided on the top of the sealing cover 41.

[0023] Through the above technical solution, after the vacuum pump 51 is started, the air inside the mixing tank 3 is extracted by the vacuum tube 52 to form a negative pressure environment. The formation of negative pressure causes the dissolved gas and suspended bubbles in the paint to escape quickly, thereby achieving efficient defoaming and significantly improving the uniformity and density of the paint. After defoaming, the internal structure of the paint is more compact, which can maintain stable flow characteristics during subsequent stirring and spraying, avoiding paint film pores, peeling or flaking caused by residual bubbles. During the stirring process, the viscometer 56 can monitor the viscosity change of the paint in real time. Through precise control of viscosity, it can prevent the increase of stirring resistance caused by excessive viscosity, and also avoid insufficient fluidity caused by excessively low viscosity. The synergistic effect of vacuum extraction and viscosity monitoring provides a reliable guarantee for the quality consistency of different batches of paint, ensuring that the viscosity of each batch of paint is kept within a preset narrow range. The stability of viscosity directly affects the curing rate of the paint. If the viscosity fluctuates too much, regional differences will occur in the curing process, resulting in some areas drying too quickly and other areas curing late, which in turn leads to the hidden dangers of uneven color, reduced nighttime reflectivity and paint film cracking.

[0024] Specifically, such as Figure 1 As shown, the mixing tank 3 is equipped with a control panel, which is electrically connected to the motor 411, vacuum pump 51, pressure gauge body 54 and viscometer 56.

[0025] The above technical solution allows the control panel to control the opening and closing of the motor 411, vacuum pump 51, pressure gauge 54, and viscometer 56.

[0026] In use, paint raw materials and water are added to the mixing tank 3 through the water inlet valve 57 and the sealed feed port 58. Then, the motor 411 is started. After starting, the motor 411 drives the driving bevel gear 48 to rotate. Simultaneously, the driving bevel gear 48, through meshing, drives the driven bevel gears 49 on both sides to rotate together, thereby causing the driven bevel gear 410 to rotate as well. It is worth noting that the rotation direction of the driven bevel gear 410 is completely opposite to that of the driving bevel gear 48. This reverse transmission enables bidirectional power distribution in the mechanical system. (The text abruptly ends here, likely due to an incomplete sentence or missing information.) 8. While rotating and driving the hollow rod 42, the hollow rod 42 in turn drives the stirring disc 43 to rotate clockwise or counterclockwise. Since the driven bevel gear 2410 and the driving bevel gear 48 rotate in opposite directions, it synchronously causes the hollow rod 42 to rotate in the opposite direction. This causes the scraper 45 and the stirring blade 46 to rotate in the opposite direction to the stirring disc 43, so that the stirring disc 43 and the stirring blade 46 work simultaneously under different directions, forming a vertical and horizontal cross-flow shearing field. The stirring disc 43 is responsible for a large-scale overall overturning of the paint in the middle of the tank, while... The stirring blades 46 generate fine, localized agitation at the edge of the tank wall. This synergistic effect of opposite directions significantly improves the uniformity of paint mixing, preventing quality issues such as color variations and nighttime reflectivity loss caused by pigment aggregation or uneven viscosity. At this point, the vacuum pump 51 is activated. Once activated, the vacuum pump 51 uses the vacuum tube 52 to extract air from the mixing tank 3, creating a negative pressure environment. This negative pressure causes dissolved gases and suspended bubbles in the paint to escape rapidly, achieving efficient defoaming and significantly improving the uniformity and density of the paint. After defoaming, the interior of the paint... The structure is more compact, which can maintain stable flow characteristics during subsequent mixing and spraying, avoiding paint film pores, peeling or flaking caused by residual air bubbles. During the mixing process, the viscometer 56 can monitor the viscosity change of the paint in real time. Through precise control of viscosity, it can prevent the increase of mixing resistance caused by excessive viscosity, and also avoid insufficient flowability caused by excessively low viscosity. The synergistic effect of vacuum pumping and viscosity monitoring allows the discharge valve 412 to be opened after mixing is completed, and the mixed paint is scraped into the discharge valve 412 and discharged under the action of the scraper 45.
