Description

Technical Field

[0001] This invention belongs to the field of high-pressure airless spraying technology, specifically referring to an adjustable mobile high-pressure airless spraying machine. Background Technology

[0002] The working principle of airless spraying technology is as follows: liquid paint is pressurized by a booster pump, such as a plunger pump or diaphragm pump, and then the pressurized paint is delivered to the airless spray gun via a high-pressure hose. When the paint reaches the airless nozzle, the pressure is released, and it is instantly atomized and sprayed onto the surface of the object to be coated, ultimately forming a uniform coating layer. Because no air is mixed into the paint during this process, it is called airless spraying, or simply airless spraying.

[0003] The existing adjustable mobile high-pressure airless spraying machine has the following problems: When the existing adjustable mobile high-pressure airless sprayer sprays the metal sheet face down after spraying the front side, the thick coating on the metal sheet causes the liquid to shrink from a flat film state and form droplets, which disrupts the continuity and uniformity of the coating. Furthermore, the curing process of the traditional adjustable mobile high-pressure airless sprayer is slow after spraying both sides of the metal sheet, which prolongs the overall spraying operation time. Therefore, it cannot meet the current demand for adjustable mobile high-pressure airless sprayers. Summary of the Invention

[0004] In response to the above situation and to overcome the shortcomings of the existing technology, this solution provides an adjustable mobile high-pressure airless sprayer that can pre-cur the coating on the metal plate after it is flipped over, ensuring the quality of the metal plate spraying, and can preheat the surface of the uncoated metal plate, shortening the curing time of the double-sided coating on the metal plate and improving the efficiency of the metal plate spraying.

[0005] The technical solution adopted in this solution is as follows: This solution proposes an adjustable mobile high-pressure airless sprayer, including a support frame, a flipping block, a frame clamping positioning mechanism, and a flow-preventing pre-fixing mechanism. The flipping block is rotatably mounted on the inner wall of the support frame. The frame clamping positioning mechanism is located on the side of the flipping block away from the support frame. The flow-preventing pre-fixing mechanism is mounted on the frame clamping positioning mechanism. The frame clamping positioning mechanism includes a frame locking mechanism, a flipping mechanism, and a clamping mechanism. The frame locking mechanism is located on the side of the flipping block away from the support frame. The flipping mechanism is located on the side of the support frame away from the frame locking mechanism. The clamping mechanism is mounted on the frame locking mechanism. The flow-preventing pre-fixing mechanism includes an insert plate mechanism, a heat source mechanism, and a spraying mechanism. The insert plate mechanism is mounted on the frame locking mechanism. The heat source mechanism is located at the end of the frame locking mechanism away from the support frame. The spraying mechanism is located on the upper wall of the support frame.

[0006] As a further preferred embodiment of the present invention, the frame locking mechanism includes a large U-shaped frame, a guide rod, a clamping spring, and a small U-shaped frame. The large U-shaped frame is located on the side of the flipping block away from the support frame. The guide rod is symmetrically located on the side of the large U-shaped frame away from the flipping block and is slidably located inside the large U-shaped frame. The small U-shaped frame is located on the side of the guide rod away from the large U-shaped frame. The clamping spring is located on the outside of the guide rod between the large U-shaped frame and the small U-shaped frame. The flipping mechanism includes a flipping shaft, a locking nut, and a flipping wheel. The flipping shaft passes through the support frame and connects to the flipping block. The locking nut is located on the outside of the flipping shaft and is threadedly connected to the flipping shaft. The flipping wheel is located on the side of the flipping shaft away from the support frame. The clamping mechanism includes an adjusting bolt, a clamping plate, and a fixing groove. The fixing groove is located on the inner wall of the large U-shaped frame and the small U-shaped frame, and the fixing groove is open at both ends. The clamping plate is slidably located on the inner wall of the fixing groove. The adjusting bolt passes through the large U-shaped frame and the small U-shaped frame and is rotatably connected to the clamping plate.

[0007] In use, pull the small U-shaped frame. Under the deformation of the clamping spring, the small U-shaped frame slides along the inner wall of the large U-shaped frame via the guide rod. The small U-shaped frame moves away from the side wall of the large U-shaped frame. Place one end of the metal plate into the fixing groove set in the inner wall of the large U-shaped frame. Rotate the adjusting bolts set on the large U-shaped frame and the small U-shaped frame respectively. The adjusting bolts rotate along the large U-shaped frame and the small U-shaped frame. The adjusting bolts drive the clamping plates to slide relative to each other along the inner wall of the fixing groove. The bottom wall of the metal plate is in contact with the clamping plate at the bottom of the large U-shaped frame. Release the small U-shaped frame. Under the restoring force of the clamping spring, the small U-shaped frame is in contact with the side wall of the large U-shaped frame. The bottom wall of the end of the metal plate away from the large U-shaped frame is in contact with the upper wall of the clamping plate at the bottom of the small U-shaped frame. The side of the metal plate away from the large U-shaped frame is in contact with the inner wall of the fixing groove set in the inner wall of the small U-shaped frame, thus completing the clamping of the metal plate.

[0008] Preferably, the insertion plate mechanism includes an insertion plate slot, an insertion copper plate, and a heat insulation block. The insertion plate slot is symmetrically arranged on the inner walls of the support frame and the large U-shaped frame, and the insertion plate slot is through-hole. The insertion copper plate is slidably disposed inside the insertion plate slot, and the heat insulation block is disposed on the side of the insertion copper plate near the support frame. The heat source mechanism includes a thermoelectric cooling element assembly, a heating groove, and a heating port. Multiple sets of thermoelectric cooling element assemblies are respectively disposed through the upper and lower walls of the small U-shaped frame. The heating groove is disposed inside the small U-shaped frame near the end of the thermoelectric cooling element assembly, for heating... The groove is a through-hole design, with the end of the copper plate inserted away from the heat insulation block located inside the heating groove. The heating port is located between the heating groove and the heating end of the thermoelectric cooling fin assembly. The spraying mechanism includes a paint holder, a paint cylinder, a high-pressure airless spraying pump, and a spraying telescopic tube. The paint holder is located on the upper wall of one end of the large U-shaped frame. The paint cylinder is rotatably located on the upper wall of the paint holder. The high-pressure airless spraying pump is located on the side wall of the paint cylinder. The liquid inlet end of the high-pressure airless spraying pump is located through the inside of the paint cylinder. The spraying telescopic tube is located at the spraying end of the high-pressure airless spraying pump.

[0009] In use, the end of the copper plate inserted near the heating tank is located inside the plate slot. Paint is injected into the paint cylinder, and the high-pressure airless spray pump is started. The paint inside the paint cylinder is atomized by the high-pressure airless spray pump and then transported to the inside of the spray telescopic tube. A nozzle is pre-installed at the end of the spray telescopic tube away from the high-pressure airless spray pump. The nozzle sprays the atomized paint onto the upper surface of the metal plate.

[0010] Specifically, the thermoelectric cooling chip assembly is model SP4040079L1-LT.

[0011] The beneficial effects achieved by this solution using the above structure are as follows: Compared with existing technologies, this solution combines a frame-clamping positioning mechanism with a flow-prevention pre-curing mechanism. Through the coordinated use of the frame locking mechanism, flipping mechanism, clamping mechanism, insert plate mechanism, heat source mechanism, and spraying mechanism, double-sided spraying of metal plates can be performed without affecting the uniformity of the coating. By curing the coating on the bottom side of the metal plate, the fluidity of the paint is reduced, preventing gravity from continuously pulling the liquid paint downwards when the sprayed side is facing down, causing it to accumulate at the lowest point and form drips. This ensures the uniformity of the coating after spraying. Furthermore, while curing the sprayed side of the metal plate, the unsprayed side of the metal plate can be preheated, thereby accelerating the curing process and shortening the spraying operation time, thus improving the efficiency of double-sided spraying of metal plates.

[0020] The thermoelectric cooling chip assembly 23 is model SP4040079L1-LT.

[0021] In practical use, initially, insert the copper plate 20 away from the heating tank 24, pull the small U-shaped frame 8, and the small U-shaped frame 8 will slide along the inner wall of the large U-shaped frame 5 via the deformation of the clamping spring 7 and the guide rod 6. The small U-shaped frame 8 will then move away from the side wall of the large U-shaped frame 5. Place one end of the metal plate into the fixing groove 16 provided on the inner wall of the large U-shaped frame 5, and rotate the adjusting bolts 14 provided on both the large U-shaped frame 5 and the small U-shaped frame 8. The adjusting bolts 14 will rotate along the inner walls of the large U-shaped frame 5 and the small U-shaped frame 8. Bolt 14 drives clamping plate 15 to slide relative to each other along the inner wall of fixing groove 16. The bottom wall of metal plate is in contact with clamping plate 15 at the bottom of large U-shaped frame 5. Small U-shaped frame 8 is released. Small U-shaped frame 8 is in contact with side wall of large U-shaped frame 5 by the elastic rebound force of clamping spring 7. The bottom wall of metal plate away from large U-shaped frame 5 is in contact with upper wall of clamping plate 15 at the bottom of small U-shaped frame 8. The side of metal plate away from large U-shaped frame 5 is in contact with inner wall of fixing groove 16 at the inner wall of small U-shaped frame 8, thus completing the clamping of metal plate. Paint is injected into the paint cylinder 28, and the high-pressure airless spray pump 29 is started. The paint inside the paint cylinder 28 is atomized by the high-pressure airless spray pump 29 and enters the spray telescopic tube 30. A nozzle is installed in advance at the end of the spray telescopic tube 30 away from the high-pressure airless spray pump 29. The nozzle sprays the atomized paint onto the upward side of the metal plate. The operator stretches the spray telescopic tube 30 to extend it, which drives the nozzle to spray the metal plate surface evenly. After the operator finishes spraying the upper surface of the metal plate, the high-pressure airless spray pump 29 is turned off, and the downward side of the metal plate is sprayed. The operator rotates the locking nut 11, which rotates along the flipping shaft 10 away from the side wall of the support frame 1. The flipping shaft 10 changes from a fixed state to a movable state. The paint cylinder 28 is rotated, which drives the spraying telescopic tube 30 to rotate from above the metal plate to above the support frame 1. The flipping wheel 12 is rotated, which drives the flipping block 2 to rotate through the flipping shaft 10. The flipping block 2 drives the large U-shaped frame 5 to flip. The large U-shaped frame 5 drives the small U-shaped frame 8 through the guide rod 6 to complete the flipping operation of the metal plate. At this time, the sprayed surface of the metal plate is placed downwards, and the unsprayed surface of the metal plate is placed upwards. Since the metal sheet needs to be used in a corrosion-resistant environment, the anti-corrosion coating on its surface is relatively thick. Before spraying the other side of the metal sheet, in order to prevent the liquid coating from being continuously pulled down by gravity when the sprayed side is facing down, causing it to accumulate at the lowest point and form drips, it is necessary to treat the area of ​​the metal sheet after spraying to ensure the uniformity of the coating after the metal sheet is flipped over. Push the heat insulation block 21 at the bottom of the large U-shaped frame 5. The heat insulation block 21 drives the inserted copper plate 20 to slide into the heating tank 24 along the insertion plate groove 19. Start the thermoelectric cooling chip group 23. The heat generated by its heating end heats the inserted copper plate 20 through the heating port 25. After the inserted copper plate 20 is heated, it cures the coating layer on the metal plate facing down, thereby reducing the fluidity of the coating and avoiding the occurrence of sagging. When heating and curing the coating on the downward side of a metal plate, the upward-facing area to be sprayed can be preheated, thereby accelerating the curing speed of the subsequent coating on that side, shortening the spraying time of the metal plate, and improving the efficiency of the spraying operation. Rotate the paint cylinder 28, which drives the spraying telescopic tube 30 to rotate from above the support frame 1 to above the metal plate. Turn on the high-pressure airless spray pump 29, which atomizes the paint inside the paint cylinder 28 and delivers it to the spraying telescopic tube 30. The spraying telescopic tube 30 uses nozzles to spray the atomized paint onto the upward-facing side of the metal plate. After the metal plate is sprayed, turn off the high-pressure airless spray pump 29 to stop spraying the metal plate. Push the heat insulation block 21 on the upper part of the large U-shaped frame 5. The heat insulation block 21 drives the inserted copper plate 20 to be inserted into the heating groove 24 on the upper part of the small U-shaped frame 8. The thermoelectric cooling plate group 23 uses the heating end to heat the inserted copper plate 20 through the heating groove 24. After the temperature of the inserted copper plate 20 rises, the coating on the current upward side of the metal plate is cured. After the coating layer on the newly sprayed surface (originally facing up) of the metal plate has cured, pull the heat insulation block 21 at the bottom of the large U-shaped frame 5. The heat insulation block 21 will cause the inserted copper plate 20 to be pulled out from the heating tank 24. The inserted copper plate 20 will be placed away from the heating tank 24. After the inserted copper plate 20 at the bottom of the large U-shaped frame 5 is completely pulled out, the inserted copper plate 20 at the top of the large U-shaped frame 5 will be pulled out to complete the curing of the double-sided coating of the metal plate. Then, pull the small U-shaped frame 8. The small U-shaped frame 8 uses the deformation of the clamping spring 7 to drive the guide rod 6 to slide along the inner wall of the large U-shaped frame 5. The small U-shaped frame 8 moves away from the side wall of the large U-shaped frame 5, and the sprayed metal plate is taken out from between the large U-shaped frame 5 and the small U-shaped frame 8. The above operation can be repeated for the next use.
