Description

Technical Field

[0001] This utility model relates to the field of sprayer technology, specifically to a rotatable polyurethane polyurea sprayer. Background Technology

[0002] Polyurethane polyurea is a high-performance polymer material belonging to the category of elastomers. It is widely used in industries such as industry, construction, and transportation. In some basements and bathrooms, polyurethane polyurea is often sprayed to provide long-term waterproofing. It can also be sprayed on the concrete surfaces of bridges and dams to prevent steel corrosion and structural aging.

[0003] During spraying, a spray gun is typically used to spray polyurethane polyurea, while the other end is held by the worker to aim the spray at the area to be sprayed. Because the spray gun and the spray gun are connected by a hose, the worker can rotate the handheld spray gun to spray different areas when spraying at different angles.

[0004] While it is easier to control the direction of spraying by hand, it is still quite strenuous. Furthermore, when spraying, the worker is close to the sprayed polyurethane / polyurea, and some of the polyurethane / polyurea may be scraped to the back and adhere to the worker's body after spraying.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1 to 5 A rotatable polyurethane polyurea spray gun includes a movable frame 2 with casters 1, a spraying component, a height adjustment component, a rotating half-ring 3, and a rotating component. The spraying component is mounted on the movable frame 2, the height adjustment component is mounted on the movable frame 2 and is used to adjust the spraying height, the rotating half-ring 3 is mounted on the height adjustment component and has a semi-circular groove at its top end, and the rotating component is mounted on the rotating half-ring 3 and is used to drive the spraying component to rotate.

[0026] like Figure 2As shown, when spraying polyurethane polyurea, the device is first moved to the spraying location using casters 1, and then casters 1 are locked. Spraying is then performed using the spraying assembly, which includes a storage cylinder 4, a connecting hose 5, and a spray gun 6. The storage cylinder 4 is mounted on the movable frame 2. One end of the connecting hose 5 is connected to the side of the storage cylinder 4, and the other end is connected to the spray gun 6. Specifically, when the spray gun 6 is activated, it generates negative pressure through the high-speed flow of compressed air, absorbing the material. This absorbs the material in the storage cylinder 4 through the connecting hose 5 and sprays it out. It should be noted that the spray gun 6 is an automatic spray gun 6, which can spray without manual handling, such as the GRACO AIRPRO automatic spray gun 6 series. In this case, the spray gun 6 can be mounted on the mounting frame 16 using bolts.

[0027] like Figure 4 and Figure 5 As shown, during spraying, the spray gun 6 can be rotated on the rotating semi-ring 3 via the rotating assembly, thereby adjusting the angle. The rotating assembly includes a mounting plate 13, a second motor 14, a rotating rod 15, a mounting bracket 16, and a support assembly. The mounting plate 13 is fixedly installed at the bottom end of the rotating semi-ring 3. The second motor 14 is installed on the mounting plate 13. One end of the rotating rod 15 is slidably installed in the semi-circular groove of the rotating semi-ring 3, and the output end of the second motor 14 is fixedly connected to the other end of the rotating rod 15. The mounting bracket 16 is fixedly installed on the rotating rod 15, and the spray gun 6 is detachably installed on the mounting bracket 16. The support assembly is set on the mounting plate 13 and includes a connecting... The connecting plate 17, support rod 18, and support semi-ring 19 are fixedly installed on the side of the mounting plate 13. Two support rods 18 are fixedly installed on the top of the connecting plate 17, and support semi-rings 19 are fixedly installed on the top of each of the two support rods 18. Specifically, when the second motor 14 is started, the output end of the second motor 14 drives the rotating rod 15 to rotate. It should be noted that the connection between the rotating rod 15 and the second motor 14 is at the center of the rotating semi-ring 3, so that the other end of the rotating rod 15 can drive the mounting bracket 16 to slide in the semi-circular groove of the rotating semi-ring 3, thereby adjusting the angle. During adjustment, the connecting hose 5 can prevent it from being placed on the support semi-ring 19.

[0028] like Figure 3As shown, the height can be adjusted by different spray positions. The height adjustment component includes a support cover 7, a reciprocating screw 8, a first motor 10, and a synchronization component. Two support covers 7 are fixedly installed on the top of the moving frame 2. The reciprocating screw 8 is rotatably installed in one of the support covers 7, and a matching crescent slider 9 is installed on the reciprocating screw 8. The first motor 10 is installed on the support cover 7, and the output end of the first motor 10 is coaxially connected to the reciprocating screw 8. The synchronization component is set in the other support cover 7. The synchronization component includes a synchronization rod 11 and a synchronization block 12. The synchronization rod 11 is fixedly installed in the other support cover 7, the synchronization block 12 is slidably installed on the synchronization rod 11, and the rotating half ring 3 is fixedly installed between the synchronization block 12 and the crescent slider 9.

[0029] Specifically, starting the second motor 14 causes the output of the second motor 14 to drive the reciprocating screw 8 to rotate within the support cover 7. This allows the crescent-shaped slider 9 to rise and fall on the reciprocating screw 8. Connected by the rotating half-ring 3, it drives the synchronizing block 12 at the other end to rise and fall synchronously on the synchronizing rod 11. It should be noted that the shape of the crescent-shaped slider 9 matches the spiral groove of the reciprocating screw 8. When the reciprocating screw 8 rotates, the sidewall of the spiral groove generates an axial thrust on the crescent-shaped slider 9 embedded within it. This allows the crescent-shaped slider 9 to move along the axial trajectory of the reciprocating screw 8, thus moving up and down. When the crescent-shaped slider 9 reaches the end of the reciprocating screw 8, it smoothly transitions to the reverse spiral groove, achieving reciprocating movement. This is a well-known technology and will not be elaborated further. Furthermore, it enables the spray gun 6 to adjust its height.

[0030] Working Principle: When the rotatable polyurethane / polyurea sprayer 6 is spraying, the device is first moved to the spraying location by the casters 1, and then the casters 1 are locked. After that, the spray gun 6 is started. The spray gun 6 generates negative pressure through the high-speed flow of compressed air to absorb the material. The material in the storage cylinder 4 is then absorbed and sprayed out through the connecting hose 5. During spraying, the second motor 14 is started. The output end of the second motor 14 drives the rotating rod 15 to rotate. The other end of the rotating rod 15 drives the mounting bracket 16 to slide in the semi-circular groove of the rotating half-ring 3, thereby adjusting the angle of the spray gun 6. At the same time, the second motor 14 is started. The output end of the second motor 14 drives the reciprocating screw 8 to rotate in the support cover 7. The crescent slider 9 can then rise and fall on the reciprocating screw 8. Under the connection of the rotating half-ring 3, the synchronous block 12 at the other end moves synchronously up and down on the synchronous rod 11, thereby adjusting the height of the spray gun 6.

[0031] It should be added that, because the connecting hose 5 is made of a soft material, when the spray gun 6 rotates at an angle and is raised in height, the connecting hose 5 can move synchronously and will not affect the spraying of polyurethane polyurea.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
