Description

Technical Field

[0001] The invention relates to the technical field of road marking construction devices, and in particular to a road marking multi-component paint mixing device. Background Art

[0002] With the rapid development of highway construction in my country, more and more road marking construction is being carried out. At present, two-component road marking paint is a road marking paint with relatively mature technology. Two-component road marking paint is composed of two-component paint. Generally, the raw materials of the two components can be stored stably separately. When spraying markings, the two components need to be evenly mixed in a certain proportion to produce a chemical reaction. The mixed two-component paint is used once on site. The existing construction method is to first stir and mix the two-component paint in a container, and then use it for road marking spraying construction, and then spray the two-component road marking paint after the chemical reaction onto the ground through a spray gun.

[0003] However, it is difficult to accurately control the amount of two-component paint being stirred and mixed at any time during the current construction process. The construction environment and weather are changeable in real time during on-site construction, which delays the construction progress. The mixed two-component paint may not be used up on-site at one time, resulting in solidification and waste. If small amounts are mixed in multiple times, the construction efficiency is greatly reduced. Summary of the invention

[0004] In view of the above-mentioned deficiencies in the prior art, the present invention provides a road marking multi-component paint mixing device, which is characterized by comprising

[0005] A first mixing component, wherein a spiral cavity is provided inside the first mixing component, and the multi-component coatings are mixed together through the spiral cavity to complete mixing;

[0006] A second mixing component, wherein a containing chamber is arranged inside the second mixing component; the second mixing component is connected to the first mixing component, and the multi-component coating enters the internal containing chamber of the second mixing component through the first mixing component; the second mixing component is provided with an outlet, and the internal containing chamber and the outlet are connected through a spiral channel.

[0011] The spiral column is provided with a transverse feed hole at the upper part and a transverse discharge hole at the lower part;

[0012] The feed hole is located at the upper end of the spiral groove and is connected to the upper countersunk hole;

[0013] The discharge hole is located at the lower end of the spiral groove and is connected to the lower through hole;

[0014] The bottom of the outer sleeve is provided with a spraying discharge hole which can be communicated with the sinking hole at the bottom of the spiral column.

[0015] Preferably, the groove cross-section of the spiral groove is trapezoidal.

[0016] Preferably, the groove-shaped cross-section is an isosceles trapezoid.

[0017] Preferably, the total length of the spiral groove is 26 to 34 mm.

[0018] Preferably, the surface roughness Ra value of the inner surface of the outer sleeve and the outer surface of the spiral column is not greater than 0.4 mm.

[0019] Preferably, the outer sleeve has an internal thread for connecting with the second mixing assembly at the upper portion and an external thread for connecting with a spraying device at the lower portion.

At the same time, it is avoided that the two-component paint cannot be used up at one time on site after being pre-mixed, resulting in the curing being scrapped, and accurate control of the mixing amount and usage amount of the two-component paint is achieved.

[0034] A second mixing component 1, wherein a receiving chamber is provided inside the second mixing component 1 for receiving the two-component paint mixed by the first mixing component 2; the second mixing component 1 is connected to the first mixing component 2, and the two-component paint enters the internal receiving chamber of the second mixing component 1 through the first mixing component 2; the second mixing component is provided with an outlet 3, and the internal receiving chamber and the outlet 3 are connected through a spiral channel, and the first mixing components 2 are set to 4, and the 4 first mixing components 2 simultaneously transport the two-component paint to the receiving chamber, and the two-component paint is transported to the spray gun after being mixed again through the spiral channel designed between the internal receiving chamber and the outlet 3.

[0035] like Figures 2 to 6 As shown, the first mixing component 2 includes an outer sleeve 10 and a spiral column 20. The spiral column 20 is placed in the outer sleeve 10 to fit the inner wall thereof. The outer wall of the spiral column 20 is provided with a spiral groove 21. The spiral groove 21 and the inner wall of the outer sleeve 10 form a spiral cavity, and the spiral cavity is used to pass the multi-component coating.

[0036] The top of the spiral column 20 is provided with an upper countersunk hole 25, and the bottom is provided with a lower through hole 26; the upper part of the spiral column 20 is provided with a transverse feed hole 22, and the lower part is provided with a transverse discharge hole 23; the feed hole 22 is located at the upper end of the spiral groove 21 and is connected with the upper countersunk hole 25; the discharge hole 23 is located at the lower end of the spiral groove 21 and is connected with the lower through hole 26; the bottom of the outer sleeve 10 is provided with a spray discharge hole 13 which can be connected with the countersunk hole 26 at the bottom of the spiral column 20.

After the connection, the spiral column 20 is tightened and fixed in the outer sleeve 10, and the lower part is connected to the second mixing component 1 through the external thread 12.

[0038] During the construction of two-component paint, the A component paint and the B component paint are pressurized and enter the feed hole 22 through the upper countersunk hole 25 at the top of the spiral column 20. The two-component paint is fully mixed while moving along the spiral line of the spiral groove 21 and the inner wall of the outer sleeve 10 to form a spiral cavity, and the first uniform mixing can be completed in a short time.
