Description
A mixing device for waterproof coating Technical Field
[0001] This invention relates to the field of waterproof coating production equipment technology, and more specifically to a mixing device for waterproof coatings. Background Technology
[0002] A waterproof coating mixing device is a device that mixes various raw materials used in the production of waterproof coatings, such as hot-melt modified asphalt, some additives, solutes, and solvents. The raw materials used in the production of waterproof coatings are relatively viscous and difficult to mix evenly.
[0003] The waterproof coating mixing device includes a mixing tank with an upper inlet and a lower outlet. A stirring motor is installed on the mixing tank, and a stirring shaft extends into the mixing tank. The stirring shaft has stirring blades inside the mixing tank, and the stirring motor is connected to the stirring shaft. In use, the raw materials are put into the mixing tank through the inlet, and the stirring motor is started to stir the materials inside the mixing tank. The stirred waterproof coating flows out through the outlet.
[0004] In the existing technology, the stirring shaft of the waterproof coating mixing device cannot be raised or lowered, and the stirring blades can only stir within their lateral range. This results in poor material mixing in the longitudinal range far from the stirring blades, which has the disadvantage of poor stirring effect and needs to be improved. Summary of the Invention
[0005] The purpose of this invention is to address the above-mentioned shortcomings by providing a mixing device for waterproof coatings with good mixing effect.
[0006] The technical solution of the present invention is implemented as follows: a mixing device for waterproof coating includes a mixing tank with an upper inlet and a lower outlet, a mixing motor installed on the mixing tank, the mixing tank having a mixing shaft hole, and a mixing shaft extending into the mixing tank through the mixing shaft hole, the mixing shaft having mixing blades inside the mixing tank, and the mixing motor being connected to the mixing shaft; characterized in that: multiple telescopic components arranged in a circumferential array around the mixing shaft are also installed on the mixing tank around the mixing shaft hole, the telescopic components having an upper telescopic end, and the mixing motor being installed on the telescopic end.
[0007] Furthermore, a wedge-shaped ring is connected below the multiple telescopic components. This wedge-shaped ring has a structure with one side thicker than the other. This wedge-shaped ring is the upper wedge-shaped ring. Below the upper wedge-shaped ring is another wedge-shaped ring, which is the lower wedge-shaped ring. The lower part of the upper wedge-shaped ring and the upper part of the lower wedge-shaped ring have mutually cooperating circular first raceways, and a first ball is located within the first raceway, enabling the lower wedge-shaped ring and the upper wedge-shaped ring to rotate relative to each other. The wedge-shaped ring has a through-hole in the middle, through which the stirring shaft passes. A first motor is mounted on the side of the lower wedge-shaped ring, and a first gear is connected to the output shaft of the first motor. A first gear ring is located around the upper wedge-shaped ring, and the first gear and the first gear ring mesh. Driven by the motor, the upper wedge-shaped ring and the lower wedge-shaped ring continuously change their positional relationship, causing the trajectory of the stirring shaft to form a conical structure.
[0008] Furthermore, a circular ring is installed below the lower wedge-shaped ring, and a circular second slide is provided between the lower wedge-shaped ring and the circular ring. A second ball bearing is located inside the second slide. A second gear ring is provided around the lower wedge-shaped ring. A second motor is also installed on the mixing tank. A second gear is provided on the power output shaft of the second motor. The second gear and the second gear ring mesh with each other. Under the action of the second motor, the lower wedge-shaped ring rotates around the mixing shaft hole.
[0009] Preferably, there are three telescopic components.
[0010] In one technical solution, the stirring blades are also connected to the stirring shaft by a spring.
[0011] In one technical solution, a rubber sheet is also installed at the free end of the stirring blade.
[0012] In one technical solution, the time it takes for the second motor to make the lower wedge ring rotate one revolution is different from the time it takes for the first motor to make the upper wedge ring rotate one revolution.
[0013] Preferably, the stirring blades are multi-layered from top to bottom on the stirring shaft, the distance between the upper and lower stirring blades is the height between the stirring blades, and the extension and retraction range of the telescopic component is equal to the height between the stirring blades.

[0022] The technical solution of the present invention will be further described below with reference to the embodiments.
[0023] As shown in Figures 1, 2, 3, 4, and 5, a mixing device for a waterproof coating includes a mixing tank 1 with an upper inlet 11 and a lower outlet 12. A mixing motor 13 is installed on the mixing tank. The mixing tank has a mixing shaft hole, and a mixing shaft 14 extends into the mixing tank through the mixing shaft hole. The mixing shaft has mixing blades 15 inside the mixing tank. The mixing motor is also connected to the mixing shaft. The device is characterized in that multiple telescopic components 2 are also installed on the mixing tank around the mixing shaft hole in a circumferential array around the mixing shaft. The telescopic components have an upper telescopic end, and the mixing motor is installed on the telescopic end.
[0024] Furthermore, the telescopic component is also connected to a control device 7, which is a device for controlling the telescopic component's extension and retraction.
[0025] The telescopic component, such as a telescopic hydraulic cylinder or a telescopic pneumatic cylinder, is a component in the prior art, as long as it can extend and retract.
[0026] The above-mentioned configuration of the present invention can realize the raising or lowering of the stirring shaft, thereby driving the stirring blades to rise and fall. That is, during the stirring process, the stirring blades can change position up and down, resulting in a more uniform stirring effect.
[0027] Furthermore, a wedge-shaped ring 3 is connected below the multiple telescopic components. The wedge-shaped ring has a structure with one side thicker than the other. This wedge-shaped ring is the upper wedge-shaped ring 31. Below the upper wedge-shaped ring is another wedge-shaped ring, which is the lower wedge-shaped ring 32. The lower part of the upper wedge-shaped ring and the upper part of the lower wedge-shaped ring have mutually cooperating circular first raceways 35, and a first ball bearing 33 is located in the first raceway, which allows the lower wedge-shaped ring and the upper wedge-shaped ring to rotate relative to each other. The wedge-shaped ring has a through-hole 34 in the middle, through which the stirring shaft passes. A first motor 4 is installed on the side of the lower wedge-shaped ring. A first gear 41 is connected to the output shaft of the first motor. A first gear ring 311 is located around the upper wedge-shaped ring, and the first gear and the first gear ring mesh. Driven by the motor, the upper wedge-shaped ring and the lower wedge-shaped ring continuously change their positional relationship, so that the trajectory of the stirring shaft forms a conical structure.
[0028] The above-mentioned configuration of the present invention enables the stirring shaft to continuously change position during the stirring process, so that the trajectory of the stirring shaft forms a conical structure, which can lead to a better stirring effect.
[0029] Of course, the lower part of the upper wedge block and the upper part of the lower wedge block have a locking mechanism that cooperates with each other. This ensures that during the mutual rotation of the upper and lower wedge blocks, the lower part of the upper wedge block and the upper part of the lower wedge block are in contact with each other, as shown in Figure 6. For example, the lower part of the upper wedge block has a dovetail groove 312, and the upper part of the lower wedge block has a protrusion installed in the dovetail groove.
[0030] Furthermore, a circular ring 5 is installed below the lower wedge ring, and a circular second slide 52 is provided between the lower wedge ring and the circular ring. A second ball bearing 51 is located inside the second slide. A second gear ring 322 is provided around the lower wedge ring. A second motor 6 is also installed on the mixing tank. A second gear 61 is provided on the power output shaft of the second motor. The second gear and the second gear ring mesh. Under the action of the second motor, the lower wedge ring rotates around the mixing shaft hole.
[0031] The above-mentioned configuration of the present invention enables the stirring shaft to continuously change position during the stirring process, the lower wedge ring to continuously change its elevation position, the stirring shaft to have a more complex running trajectory, and the waterproof coating to be stirred more evenly.
[0032] Furthermore, as shown in Figure 3, there are mating protrusions and recesses 53 on the bottom of the ring and the top of the mixing tank. In use, the recesses are fitted with the protrusions. This design ensures that the ring and the mixing tank form a single unit during use, allowing the lower wedge-shaped ring to rotate on the ring itself. That is, when the lower wedge-shaped ring rotates, the ring itself does not rotate.
[0033] Preferably, there are three telescopic components.
[0034] In one technical solution, the stirring blade is also connected to the stirring shaft by a spring 151 to prevent damage caused by collision between the free end of the stirring blade and the inside of the stirring tank.
[0035] In one technical solution, a rubber sheet 152 is also installed at the free end of the stirring blade to prevent damage caused by collision between the free end of the stirring blade and the inside of the stirring tank.
[0036] In one technical solution, the time it takes for the second motor to make the lower wedge ring rotate one revolution is different from the time it takes for the first motor to make the upper wedge ring rotate one revolution.
[0037] The above-mentioned configuration of the present invention enables a more complex running trajectory of the stirring shaft during the stirring process, resulting in more uniform stirring of the waterproof coating.
[0038] Preferably, the stirring blades are multi-layered from top to bottom on the stirring shaft, the distance between the upper and lower stirring blades is the height between the stirring blades, and the extension and retraction range of the telescopic component is equal to the height between the stirring blades.
[0039] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
