Description

Technical Field

[0001] This utility model relates to the technical field, specifically to an adjustable spraying device. Background Technology

[0002] Spray painting plays a crucial role in many aspects of modern industrial production and daily life, from car body painting in automobile manufacturing to surface coloring in furniture production, and wall decoration in building construction.

[0003] Different types of paint inevitably adhere to the inner wall of the storage tank during use. When the paint needs to be replaced for the next round of spraying, the old paint residue on the tank wall mixes with the newly added paint. This mixing severely reduces the purity of the paint, thus affecting the quality and effect of the spraying. To solve the problem of paint residue, the common practice is to use a scraper to scrape and clean the inner wall of the storage tank. However, the existing scraper design has significant limitations. Most of them are fixed in size. Since the inner diameter of storage tanks on the market varies, it is difficult for a fixed-size scraper to fit storage tanks of different inner diameters. This means that when cleaning storage tanks of different sizes, the scraper either cannot fully contact the tank wall, resulting in incomplete cleaning and the old paint remaining, or it is too large to be placed in the tank, making cleaning impossible. This greatly reduces cleaning efficiency and effectiveness, and increases the difficulty and cost for operators. Utility Model Content

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.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0028] Please see Figure 1-4 As shown, this utility model is an adjustable spraying device, comprising:

[0029] The spraying component includes a base plate 100 and a storage tank 102, the storage tank 102 being disposed on the top of the base plate;

[0030] The scraping component includes a top cover 200, a rotating rod 201, a scraper 202, a crossbar 205, and a telescopic rod 206. The top cover 200 is located on the top of the storage hopper 102. The rotating rod 201 is located in the middle of the bottom end of the top cover 200. The crossbar 205 is fixed to the outer surface of the rotating rod 201. The telescopic rod 206 is movably connected to the inside of the crossbar 205, and one side is fixed to one side of the outer surface of the scraper 202. The two ends of the crossbar 205 are provided with moving grooves 207. The moving rods 208 are located at the two ends of the telescopic rod 206 and are movably connected to the inside of the moving grooves 207. The scraper 202 is attached to the inner wall of the storage hopper 102.

[0031] Operators can easily and precisely adjust the scraper 202 according to the actual inner diameter of the storage hopper 102 by extending the telescopic rod 206 inside the crossbar 205. While the telescopic rod 206 moves the scraper 202, the moving rod 208 moves smoothly in the moving groove 207. This linkage design ensures the stability and coordination of the scraper 202 adjustment process.

[0032] A retaining ring 203 is threadedly connected to the outer surface of the moving rod 208, and a rubber ring 204 is glued to one end of the moving rod 208. The rubber ring 204 is blocked on the outer surface of the retaining ring 203.

[0033] After the scraper 202 is adjusted, the operator only needs to rotate the fixing ring 203. Since the fixing ring 203 and the moving rod 208 are connected by a thread, when the fixing ring 203 is rotated, it will be tightly fixed to the outside of the moving rod 208, thereby firmly locking the position of the scraper 202 after it has moved.

[0034] It also includes a fixing component, which includes a plug rod 300, an extension block 301 and a socket 302. The plug rod 300 is fixed to the top of the storage tank 102, the extension block 301 is fixed to both sides of the top cover 200, and the socket 302 is opened inside the extension block 301. The plug rod 300 is inserted and connected to the inside of the socket 302.

[0035] When the top cover 200 is installed on the top of the storage bin 102, the insertion rod 300 is inserted into the inside of the insertion hole 302, so that the top cover 200 is aligned with the top of the storage bin 102, which can prevent the phenomenon of misalignment after installation.

[0036] The outer surface threaded rod 404 of the insertion rod 300 is connected to a fastening ring 303, which blocks the top of the extension block 301;

[0037] The fastening ring 303 is fixed to the outside of the insertion rod 300 to fix the position of the top cover 200.

[0038] The spraying component also includes a nozzle 101, a pusher 103, and a moving wheel 104. The nozzle 101 is disposed on the top of the device base plate 100, the pusher 103 is welded to one side of the device base plate 100, and the moving wheel 104 is disposed at both ends of the device base plate 100.

[0039] The paint is poured into the storage tank 102 and transferred to the nozzle 101 by a transfer method. Finally, the paint is sprayed to the outside by the nozzle 101 to complete the spraying work.

[0040] Working principle: When this spraying device is working, the paint delivery and spraying processes are closely coordinated to form an efficient and stable spraying process. First, after the paint is poured into the storage tank 102, the flow regulating valve on the pipeline can initially control the paint delivery flow rate, while the pressure sensor monitors the pressure inside the pipeline in real time to ensure stable paint delivery. The paint flows along the paint channel to the nozzle 101. After the storage tank 102 is used, when facing storage tanks 102 with different inner diameter specifications, the operator only needs to extend the telescopic rod 206 inside the crossbar 205 to easily adjust the storage tank 102. The actual inner diameter of the scraper 202 is precisely adjusted to ensure that the scraper 202 fits perfectly with the inner wall of the storage bucket 102. Whether it is a large-diameter industrial storage bucket 102 or a small-sized household paint bucket, a seamless connection can be achieved. While the telescopic rod 206 moves the scraper 202, the moving rod 208 moves smoothly in the moving groove 207 at the same time. This linkage design ensures the stability and coordination of the scraper 202 adjustment process, and avoids the scraper 202 from deviating or shaking during the adjustment process, thereby further ensuring the tightness of the fit between the scraper 202 and the bucket wall.

[0041] Please see Figure 1 , Figure 2 As shown, this embodiment, based on the above embodiment, further includes:

[0042] The shielding component includes a shielding frame 400, a guide ring 402, a limiting plate 403, a base block 406, and a guide rod 407. The shielding frame 400 surrounds the outer surface of the nozzle 101. The base block 406 is fixed to both ends of the top of the device base plate 100. The guide rod 407 is fixed to the top of the base block 406. The guide ring 402 is disposed at both ends of the shielding frame 400 and is movably connected to the outside of the guide rod 407. The limiting plate 403 is fixed to the top of the guide rod 407.

[0043] By moving the guide ring 402 up and down outside the guide rod 407, the shielding frame 400 is moved to surround the outside of the nozzle 101, which can prevent dust from the external environment from adhering to the inside of the nozzle 101.

[0044] One end of the guide ring 402 is provided with an internal threaded ring 401, the middle of the internal threaded ring 401 is threadedly connected to a threaded rod 404, and the outer end of the threaded rod 404 is rotatably connected to a handle 405.

[0045] Rotating the handle 405 drives the threaded rod 404 to rotate, causing the threaded rod 404 to be clamped outside the guide rod 407, thus fixing the position of the shielding frame 400.

[0046] Working principle: When the spraying operation is completed or the nozzle 101 is not in use, the operator can move the masking frame 400 by using the cooperation of the guide ring 402 and the guide rod 407. The guide ring 402 can slide smoothly up and down outside the guide rod 407. The operator only needs to push gently to move the masking frame 400 outside the nozzle 101, so that it completely surrounds the nozzle 101, providing a relatively closed protective space for the nozzle 101. This effectively prevents external dust from entering the nozzle 101, minimizing problems such as nozzle clogging and uneven spraying caused by dust accumulation. When the masking frame 402... After the nozzle 101 is moved to the appropriate position, to ensure its stability, the operator can turn the handle 405. The handle 405 is connected to the threaded rod 404. Turning the handle 405 will drive the threaded rod 404 to rotate. Since the threaded rod 404 and the guide rod 407 adopt a specific clamping structure, as the threaded rod 404 rotates, it will gradually clamp tightly to the outside of the guide rod 407. When the nozzle 101 needs to be used again for spraying, the operator only needs to use the sliding function of the guide ring 402 outside the guide rod 407 to move the masking frame 400 upward to the appropriate position so that the nozzle 101 is fully exposed.
