Description
Technical Field
[0001] The utility model relates to the technical field of spraying processing, and particularly relates to a paint flow control device. Background Art
[0002] When carrying out spraying processing, the control of the paint flow is very important. This is because the principle of the spraying machine involves multiple aspects, including the nozzle principle, the paint delivery principle, the gas compression principle, and the control system principle. After the high-pressure gas or compressed air is mixed with the paint and accelerated by the nozzle, a high-speed sprayed misty substance is formed. In this process, the outlet diameter and flow rate are adjusted by controlling the flow rate and pressure of the gas and the paint, so as to achieve the output of paints with different viscosities, different particle sizes, and different spray angles.
[0003] At present, when controlling the paint flow, the paint flow is mainly controlled by manipulating the opening and closing of the valve. However, the control method by manipulating the valve has limited accuracy. The opening of the valve is prone to be too large or too small, making it difficult to adjust more precisely. When spraying smaller workpieces, accurate control cannot be achieved. At the same time, the paint is viscous in the pipeline and is easily attached to the inner side of the pipeline, affecting the flow and thus the control of the paint flow.
[0004] Therefore, it is urgent to design a paint flow control device to solve the above defects, which is particularly important. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0028] Next, in combination with the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model. Embodiment
[0029] Please refer to Figures 1 - 8 , the present utility model provides a technical solution:
[0030] A paint flow control device includes a storage cylinder 1. A dredging pipe 2 is fixedly connected to the bottom of the storage cylinder 1. A dredging mechanism 3 is fixedly installed inside the dredging pipe 2. A flow regulating sleeve 4 is fixedly installed at the bottom end of the dredging pipe 2. A flow regulating mechanism 5 is fixedly installed inside the flow regulating sleeve 4. A connecting pipe 6 is fixedly installed at the bottom end of the flow regulating sleeve 4. An air inlet pipe 7 is fixedly connected to the outside of the connecting pipe 6. A micro gear pump 8 is fixedly installed at the bottom end of the connecting pipe 6. A discharge pipe 9 is fixedly installed at the bottom of the micro gear pump 8.
[0031] First, an inlet pipe 101 is fixedly connected to the top of the storage cylinder 1. A liquid level window 102 is provided outside the storage cylinder 1. The paint is introduced into the interior of the storage cylinder 1 through the inlet pipe 101, and the remaining amount of paint inside can be observed through the liquid level window 102 at any time and added in time.
[0032] Furthermore, a motor 103 is fixedly installed at the center of the top of the storage cylinder 1. A rotating shaft 104 is fixedly installed on the output end of the motor 103 and inside the storage cylinder 1, and the rotating shaft 104 is rotatably connected to the storage cylinder 1. A plurality of stirring rods 105 are fixedly connected to the outside of the rotating shaft 104. When the paint is inside the storage cylinder 1, the motor 103 is started to drive the rotating shaft 104 to rotate, and the paint is stirred by the plurality of stirring rods 105 outside the rotating shaft 104, so that the paint remains in a flowing state, thereby ensuring the use quality of the paint.
[0033] Then, a first valve 201 is fixedly installed between the dredging pipe 2 and the storage cylinder 1. A second valve 701 is fixedly installed on the air inlet pipe 7. When using the paint, the first valve 201 is opened to roughly adjust the paint flow rate, and then a more precise adjustment is performed through the flow regulating mechanism 5 inside the flow regulating sleeve 4. The air inlet pipe 7 is externally connected to compressed air so that the paint is sprayed in a mist state when in use.
[0034] Furthermore, the dredging mechanism 3 includes drive boxes 301 fixedly installed at the upper and lower ends inside the dredging pipe 2. Both the front and rear ends of the two drive boxes 301 are fixedly connected to the inner side wall of the dredging pipe 2 through connecting rods 302. A rotating rod 303 is rotatably connected between the two drive boxes 301. Symmetrically installed on the outer side of the rotating rod 303 are connecting frames 304. Fixedly connected to one end of each of the two connecting frames 304 away from each other is a scraper 305. When the paint flows inside the dredging pipe 2, the flowing power of the paint drives the rotating rod 303 to rotate, thereby driving the scraper 305 on the connecting frame 304 to continuously scrape the paint on the inner side wall of the dredging pipe 2, thus preventing the paint from adhering and affecting its flow, and avoiding affecting the control of the paint flow rate.
[0035] Among them, rotatably connected to the inner sides of the two drive boxes 301 are drive shafts 306. Fixedly connected to the outer side of the drive shaft 306 and inside the drive box 301 is a drive gear 307. Both the upper and lower ends of the rotating rod 303 are meshed with the drive gear 307 through transmission gears 308. Fixedly connected to the outer sides of the left and right ends of the drive shaft 306 are power plates 309, and multiple power plates 309 are equidistantly distributed on the outer side of the drive shaft 306. When the paint flows, the power plates 309 drive the drive shaft 306 to rotate, and under the transmission of the drive gear 307 and the transmission gear 308, the rotating rod 303 is driven to rotate, thereby automatically driving the scraper 305 to continuously scrape the paint on the inner side wall of the dredging pipe 2 by using the flowing power of the paint.
[0036] Secondly, the flow rate adjusting mechanism 5 includes a fixed ring 501 fixedly connected to the inner bottom end of the flow rate adjusting sleeve 4. Rotatably connected to the top end inside the flow rate adjusting sleeve 4 is a movable ring 502. Multiple adjusting plates 503 are movably installed between the movable ring 502 and the fixed ring 501. Fixedly connected to the outer side of the movable ring 502 and extending to the outside of the flow rate adjusting sleeve 4 is an adjusting handle 504. When the paint flow rate needs to be adjusted more precisely, the adjusting handle 504 is swung to drive the movable ring 502 to rotate. When the movable ring 502 rotates, multiple adjusting plates 503 are synchronously driven to rotate. The multiple adjusting plates 503 can adjust the closing size of the through openings inside the fixed ring 501 and the movable ring 502, thereby more accurately controlling the paint flow rate.
[0037] Finally, a first sliding column 505 and a second sliding column 506 are respectively fixedly connected to the upper and lower sides of the adjusting plate 503. The first sliding column 505 is slidably connected to the movable ring 502 through a first guide groove 507, and the second sliding column 506 is slidably connected to the fixed ring 501 through a second guide groove 508. When the movable ring 502 rotates, the first sliding column 505 slides inside the first guide groove 507, while the second sliding column 506 slides inside the second guide groove 508, thereby guiding the movement trajectories of the multiple adjusting plates 503, and further adjusting the closing size of the through openings inside the fixed ring 501 and the movable ring 502.
[0038] In this embodiment, the implementation scenario is specifically as follows: Paint is introduced into the interior of the storage cylinder 1 through the inlet pipe 101. When the paint is inside the storage cylinder 1, it is stirred to keep the paint in a flowing state, thus ensuring the quality of the paint during use. When using the paint, the first valve 201 is opened to roughly adjust the paint flow rate. The intake pipe 7 is connected to compressed air so that the paint is sprayed in a mist when in use. When the paint enters the interior of the dredging pipe 2, when the paint is flowing, the driving shaft 306 is driven to rotate by the power plate 309. Driven by the transmission between the driving gear 307 and the transmission gear 308, the rotating rod 303 is driven to rotate. Thus, the rotating rod 303 is automatically driven to rotate by the power of the flowing paint, and the scraper 305 on the connecting frame 304 is driven to continuously scrape the paint on the inner wall of the dredging pipe 2, thereby preventing the paint from adhering and affecting its flow. When the paint flow rate needs to be adjusted more precisely, the movable ring 502 is driven to rotate by swinging the adjustment handle 504. When the movable ring 502 rotates, a plurality of adjustment plates 503 are synchronously driven to rotate. Through the plurality of adjustment plates 503, the closing size of the through openings on the inner sides of the fixed ring 501 and the movable ring 502 can be adjusted, so as to control the paint flow rate more precisely. The entire operation process is simple and convenient. Compared with the existing paint flow control devices, the present utility model can improve the accuracy of paint flow control through the design, and at the same time can prevent the paint from adhering and affecting its flow, avoiding affecting the control of the paint flow rate.
[0039] Although the embodiments of the present utility model have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
