Description

Technical Field

[0001] The invention relates to the field of coating preparation, in particular to a device for preparing water-based coating for rust-bearing coatings. Background Art

[0002] During daily operation, high-speed trains are often subject to damage to their paint surfaces due to human scratches or collisions with dust particles in the air during high-speed operation, exposing their metal shells. Paint can effectively prevent water corrosion on the metal shells, thereby extending their service life. Conventional anti-rust paints require the rust (oxide layer) on the steel substrate to be thoroughly cleaned before use to achieve good corrosion resistance. However, water-based paints for rust-resistant coatings can be applied directly to the rusted substrate surface, significantly reducing the cost of the coating.

[0003] In order to ensure the quality of the paint, it is necessary to remove the solidified materials in the raw materials during the preparation of the paint to ensure that the smoothness and beauty of the paint surface will not be affected during the coating. However, the preparation device in the existing technology is unable to filter the raw materials in a timely and effective manner during preparation, resulting in the need for secondary processing to ensure the quality of the product. For this reason, this scheme proposes a preparation device for rust-resistant water-based paint. Summary of the Invention

[0004] The device for preparing water-based paint for coating with rust proposed by the present invention solves the problem that the paint preparation device in the prior art cannot separate the solidified part in the raw material in time.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A device for preparing water-based paint for rust coating comprises a base plate and a mixing barrel mounted on the top surface of the base plate, a support plate being fixed to the top surface of the base plate, a mounting plate and a driving mechanism for driving the mounting plate to rise and fall being mounted on one side of the support plate;

[0007] A filter bucket is movably installed on the top of the mixing barrel, a filter screen is installed inside the filter bucket, and a discharge pipe is installed at the bottom of one side of the mixing barrel;

[0008] The bottom surface of the mounting plate is provided with a stirring shaft, the outer peripheral sleeve of the stirring shaft is provided with a cover plate, the top surface of the cover plate is provided with a locking mechanism, and the bottom of the stirring shaft passes through the filter screen and extends into the stirring barrel;

[0009] An air pump is also installed on the top of the mounting plate, and the air suction pipe of the air pump is communicated with the interior of the mixing barrel, and the power input shaft of the air pump is transmission-connected with the mixing shaft.

[0010] Through the above technical solution, not only can the coating raw materials be filtered conveniently and timely to remove the solidified matter in the raw materials, but also the filtering efficiency can be effectively improved.

[0011] As a further improvement of the above-mentioned solution, a mounting groove arranged in a vertical direction is opened on one side of the support plate close to the mounting plate, and the driving mechanism includes a screw rotatably connected in the mounting groove, a moving block screwed on the outer periphery of the screw, and a driving motor installed on the top surface of the support plate, one end of the moving block is fixedly connected to one end of the mounting plate, and the output shaft of the driving motor is transmission-connected to the screw.

[0012] Through the above technical solution, the rotation of the drive motor can drive the screw to rotate, thereby driving the moving block and the mounting plate to move up and down.

[0013] As a further improvement of the above solution, the two long sides of the moving block respectively abut against the two long sides of the mounting groove, and the end of the mounting plate fixed to the moving block abuts against the outer wall of the support plate.

[0014] The above technical solution can effectively prevent the installation plate from shaking during the lifting process.

[0015] As a further improvement of the above solution, a mounting bracket is fixed on the top surface of the mounting plate, a stirring motor is installed on the top surface of the mounting bracket, and the top of the stirring shaft extends above the mounting plate and is drivingly connected to the output shaft of the stirring motor.

[0016] Through the above technical solution, the rotation of the stirring motor is utilized to drive the stirring shaft to rotate.

[0017] As a further improvement of the above solution, a second scraper is fixed to the outer periphery of the stirring shaft, and the bottom surface of the second scraper abuts against the top surface of the filter screen.

[0018] Through the above technical solution, the second scraper can be driven to rotate while the stirring shaft rotates, thereby preventing the raw materials from accumulating at a certain place on the top surface of the filter screen.

[0019] As a further improvement of the above solution, a connecting ring is fixed to the bottom of the filter bucket, and the outer ring of the connecting ring is consistent with the inner ring of the mixing barrel.

[0020] The above technical solution facilitates the disassembly and assembly between the filter bucket and the mixing barrel.

[0021] As a further improvement of the above scheme, the locking mechanism includes a fixed sleeve movably mounted on the outer periphery of the stirring shaft and a locking bolt threaded on the outer periphery of the fixed sleeve. The bottom of the fixed sleeve is fixedly connected to the top surface of the cover plate, and one end of the locking bolt abuts against the outer periphery of the stirring shaft.

[0022] Through the above technical solution, the cover plate can be locked at a certain position of the stirring shaft by utilizing the static friction between the locking bolt and the stirring shaft.

[0023] As a further improvement of the above solution, a conical boss coaxially arranged therewith is fixed to the bottom of the mixing barrel, and a first scraper in contact with the surface of the conical boss and the bottom inner wall of the mixing barrel is fixed to the bottom of the mixing shaft.

[0024] The above technical solution can effectively prevent the paint from sticking to the bottom and can also prevent the raw materials from remaining at the bottom of the mixing barrel.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] 1. Through the cooperation between the stirring barrel, the filter bucket and the second scraper, the paint raw materials added to the stirring barrel can be filtered in time, and the second scraper is driven to rotate continuously while the stirring shaft rotates, so that the paint raw materials will not accumulate in a certain place of the filter screen, thereby speeding up the filtration speed.

[0027] 2. Through the cooperation between the vacuum pump and the stirring shaft, the vacuum pump can be driven to run while the stirring shaft rotates, so that the air in the mixing barrel can be extracted out, which can further speed up the filtration speed.

[0028] 3. The filter bucket is movably installed on the top of the mixing barrel, so that the solidified matter remaining on the surface of the filter can be easily cleaned. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] The present invention will be further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0037] Example 1:

[0038] Please combine Figure 1 - Figure 5 The rust-coated water-based paint preparation device of this embodiment includes a base plate 1 and a mixing barrel 3 installed on the top surface of the base plate 1, a support plate 2 is fixed to the top surface of the base plate 1, a mounting plate 7 and a driving mechanism for driving the mounting plate 7 to rise and fall are installed on one side of the support plate 2, and a mounting groove 10 arranged in a vertical direction is opened on the side of the support plate 2 close to the mounting plate 7, and the driving mechanism includes a screw 11 rotatably connected to the mounting groove 10, a moving block 19 screwed on the outer periphery of the screw 11 and a driving motor installed on the top surface of the support plate 2, one end of the moving block 19 is fixedly connected to one end of the mounting plate 7, and the output shaft of the driving motor is transmission-connected to the screw 11, and the screw 11 is driven by the rotation of the driving motor to rotate. The screw 11 rotates in different directions, thereby driving the moving block 19 to rise and fall, and then driving the mounting plate 7 to rise and fall.

[0039] The two long sides of the moving block 19 are respectively in contact with the two long sides of the mounting groove 10, and the end of the mounting plate 7 fixed to the moving block 19 is in contact with the outer wall of the support plate 2, which prevents the mounting plate 7 from rotating with the rotation of the screw rod 11 and ensures its stability during lifting.

[0040] A filter bucket 4 is movably installed on the top of the mixing barrel 3, and a filter screen 21 is installed inside the filter bucket 4. A discharge pipe 12 is installed at the bottom of one side of the mixing barrel 3. A connecting ring 17 is fixed to the bottom of the filter bucket 4. The outer ring of the connecting ring 17 is consistent with the inner ring of the mixing barrel 3. The connecting ring 17 is inserted into the inner ring of the mixing barrel 3, so that the filter bucket 4 can be conveniently installed on the top of the mixing barrel 3.

[0041] A stirring shaft 16 is installed on the bottom surface of the mounting plate 7, and a cover plate 5 is movably sleeved on the periphery of the stirring shaft 16. A locking mechanism is installed on the top surface of the cover plate 5. A feed pipe is installed on the top surface of the cover plate 5, and a closed valve is installed on the feed pipe. The bottom of the stirring shaft 16 passes through the filter screen 21 and extends into the stirring barrel 3. The filter screen 21 is rotatably sleeved on the periphery of the stirring shaft 16. The paint raw materials are filtered by the filter screen 21 and then enter the stirring barrel 3, thereby separating the solidified materials in the raw materials in time.

[0042] An air pump 9 is also installed on the top of the mounting plate 7, and the air intake pipe 13 of the air pump 9 is connected to the inside of the mixing barrel 3. The power input shaft of the air pump 9 is connected to the stirring shaft 16. A mounting bracket 8 is fixed on the top of the mounting plate 7, and a stirring motor 18 is installed on the top of the mounting bracket 8. The top of the stirring shaft 16 extends to the top of the mounting plate 7 and is connected to the output shaft of the stirring motor 18. The stirring shaft 16 is driven to rotate by the rotation of the stirring motor 18. After the stirring shaft 16 rotates, it can drive the power input shaft of the air pump 9 to rotate, thereby driving the air pump 9 to operate, so that the air in the mixing barrel 3 can be drawn out while the stirring shaft 16 rotates, thereby further accelerating the filtration speed.

[0043] A conical boss 15 coaxially arranged therewith is fixed to the bottom of the mixing barrel 3, and a first scraper 14 is fixed to the bottom of the stirring shaft 16, which is in contact with the surface of the conical boss 15 and the inner wall of the bottom of the mixing barrel 3. When the stirring shaft 16 rotates, the first scraper 14 is also driven to rotate, thereby preventing the paint from remaining in the mixing barrel 3 during discharge. The conical boss 15 can also effectively prevent the paint from gathering in the center of the bottom of the mixing barrel 3, allowing it to flow to the edge for easy discharge.

[0044] The implementation principle of this embodiment is: when preparing the paint, ensure that the cover plate 5 is covered on the top of the filter bucket 4, then open the airtight valve, input the paint raw materials from the feed pipe into the filter bucket 4, and at the same time start the stirring motor 18 to drive the stirring shaft 16 to rotate. After the paint raw materials fall on the top surface of the filter screen, they are filtered by the filter screen 21 and then fall into the mixing barrel 3 for stirring and mixing. While the stirring shaft 16 is rotating, it will also drive the power input shaft of the vacuum pump 9 to rotate, thereby driving the vacuum pump 9 to run, so that the air in the mixing barrel 3 can be extracted outward while the stirring shaft 16 rotates, thereby further accelerating the filtration speed. After the preparation is completed, the airtight valve on the discharge pipe 12 is opened. As the stirring shaft 16 rotates, the paint in the mixing barrel 3 is continuously brought to the position of the discharge pipe 12, so that the paint in the mixing barrel 3 can be discharged.

[0045] Example 2:

[0046] Combine Figure 5 Based on Example 1, this embodiment is further improved in that a second scraper 20 is fixed to the outer periphery of the stirring shaft 16, the bottom surface of the second scraper 20 abuts against the top surface of the filter screen 21, and one end of the second scraper 20 abuts against the inner ring of the filter bucket 4.

[0047] The implementation principle of this embodiment is: the stirring shaft 16 rotates and drives the second scraper 20 to rotate, so that the coating raw materials falling on the top surface of the filter 21 can be scraped flat, avoiding the coating raw materials from accumulating in a certain place, thereby accelerating the filtering speed of the raw materials.

[0048] Combine Figure 1 - Figure 2 、 Figure 4 and Figure 5 Based on Example 1, this embodiment is further improved in that: the locking mechanism includes a fixed sleeve 6 movably sleeved on the outer periphery of the stirring shaft 16 and a locking bolt screwed on the outer periphery of the fixed sleeve 6, the bottom of the fixed sleeve 6 is fixedly connected to the top surface of the cover plate 5, and one end of the locking bolt abuts against the outer periphery of the stirring shaft 16. The fixed sleeve 6 can be locked by relying on the friction between the locking bolt and the outer wall of the stirring shaft 16.

[0049] The implementation principle of this embodiment is: when the locking bolt is tightened, one end thereof abuts against the outer periphery of the stirring shaft 16, thereby locking the fixing sleeve 6 to ensure that the position of the cover plate 5 does not change; and after loosening the locking bolt, the cover plate 5 can be moved along the axial direction of the stirring shaft 16, making it convenient to open and fix it.

[0050] The above embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
