[0021] In order to make the technical problems, technical solutions and beneficial effects to be solved by this application more clearly understood, this application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0022] See also Figures 1 to 4 : A UV paint quantitative filtering and packaging machine includes a silo 1, a feed pipe 405 is fixed on the bottom side of the silo 1 and is connected through it, a delivery pipe 402 is fixed on the bottom side of the feed pipe 405 and is connected through it, a suction pipe 403 is fixed on one end of the delivery pipe 402 and is connected through it, a discharge pipe 404 is fixed on the lower side of the suction pipe 403 and is connected through it, a piston 406 is slidably connected inside the suction pipe 403, a cylinder 4 is installed on the outer wall of the silo 1, a movable rod 401 is fixedly connected between the output end of the cylinder 4 and the piston 406, a one-way tube 407 is installed inside the discharge pipe 404 and the delivery pipe 402, and a packaging tank 5 is provided on the lower side of the discharge pipe 404.

[0023] Among them, when the packaging can 5 needs to package paint, the cylinder 4 drives the piston 406 to move upward through the movable rod 401. When the piston 406 moves upward, the delivery pipe 402 and the feed pipe 405 will be in a negative pressure environment, so that the paint inside the silo 1 can be sucked into the inside of the suction pipe 403. When the cylinder 4 drives the piston 406 to move downward, the paint inside the suction pipe 403 will be discharged into the interior of the packaging can 5 through the discharge pipe 404. The suction and discharge processes are completed by driving the piston 406 by the cylinder 4, which can facilitate the packaging can 5 to quantitatively package the paint.

[0024] Furthermore, the setting of the one-way tube 407 enables both the discharge pipe 404 and the delivery pipe 402 to have the ability to conduct in one direction, such as: when the piston 406 moves upward, the one-way tube 407 inside the discharge pipe 404 is in a closed state, so that the paint inside the silo 1 can enter the interior of the suction pipe 403; when the piston 406 moves downward, the one-way tube 407 inside the delivery pipe 402 is in a closed state, so that the paint in the suction pipe 403 can be discharged into the packaging can 5.

[0025] Preferably, Figure 1 and Figure 3 As shown, a screening tube 2 is fixedly connected to the interior of the silo 1, and an auger shaft 205 is rotatably connected to the interior of the sieve tube 2. A plurality of screening holes 202 are provided on the bottom side wall of the sieve tube 2. An output motor 201 is installed on one side of the silo 1, and the output end of the output motor 201 is fixedly connected to the auger shaft 205.

[0026] When the output motor 201 drives the auger shaft 205 to rotate, the paint can be moved inside the sieve tube 2 , and the paint with smaller particles will fall into the silo 1 through the sieve holes 202 .

[0027] Preferably, Figure 3 As shown, a fixed pipe 203 is installed on the outside of the silo 1 , the fixed pipe 203 is connected to the screening pipe 2 , and the lower side of the fixed pipe 203 is spirally connected to an external pipe 204 .

[0028] When larger particles of paint cannot pass through the sieve holes 202 into the interior of the silo 1 , the auger shaft 205 can transport the larger particles of paint to the external pipe 204 to complete the collection of the larger particles of paint and prevent the larger particles of paint from accumulating inside the sieve pipe 2 .

[0029] Preferably, a feeding tank 3 is fixed to and connected to the upper side of the sieve pipe 2 , and a sieve 301 is installed inside the feeding tank 3 .

[0030] The coating inside the feeding tank 3 can be screened by the screen 301 .

[0031] Preferably, Figure 4 As shown, a rotating rod 302 is rotatably connected to the screen 301 , a scraper 303 is fixedly connected to one side of the rotating rod 302 , and the scraper 303 is connected to the screen 301 .

[0032] The scraper 303 can scrape and brush the screen 301 to prevent the screen 301 from being blocked.

[0033] Preferably, a transmission motor 306 is installed on one side of the feeding tank 3 , and a transmission rod 305 is fixedly connected to the output end of the transmission motor 306 . A bevel gear 304 is meshed between the rotating rod 302 and the transmission rod 305 .

[0034] Among them, the transmission motor 306 is installed on the outside of the feeding tank 3 to prevent the transmission motor 306 from being corroded by the paint, and when the transmission motor 306 is working, it can drive the rotating rod 302 to rotate through the transmission rod 305, so that the scraper 303 can scrape the screen 301. When the scraper 303 scrapes the screen 301, it can prevent the paint from being blocked in the screen 301, and it has a stirring effect on the paint, preventing the paint from accumulating on the screen 301.

[0035] Working principle: The paint to be filtered is placed inside the feeding tank 3, and then filtered through the screen 301 and the screen hole 202 into the interior of the silo 1; when the packaging tank 5 needs to package the paint, the cylinder 4 drives the piston 406 upward through the movable rod 401 (the cylinder 4 is externally connected to a PLC controller). When the piston 406 moves upward, the delivery pipe 402 and the feed pipe 405 are in a negative pressure environment, so that the paint inside the silo 1 can be sucked into the interior of the suction pipe 403, wherein the output length of the output end of the cylinder 4 is controlled by an external PLC. When the cylinder 4 drives the piston 406 to move to different heights, different amounts of paint can be sucked in (for example, a syringe sucks in liquid). The amount of paint is set according to the packaging quantity. When the cylinder 4 drives the piston 406 to move downward, the paint inside the suction pipe 403 will be discharged into the interior of the packaging tank 5 through the discharge pipe 404. The suction and discharge processes are completed by driving the piston 406 by the cylinder 4, which can facilitate the quantitative packaging of the paint in the packaging tank 5.

[0036] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
