Description

Technical Field

[0001] The invention belongs to the technical field of feeding devices, in particular to a powder feeding device for producing water-based paint. Background Art

[0002] Water-based paint is a paint that uses water as a solvent or dispersion medium. It is made by dispersing or dissolving a film-forming substance (resin) in water and then adding pigments, fillers, additives and other ingredients. During the production of water-based paint, a feeding device is required to add a variety of powders into the reactor for subsequent reaction work.

[0003] The patent with announcement number CN219636421U discloses a powder feeding hopper, which loosens the raw materials at the bottom of the feed hopper through the cooperation of a fixing rod and a loosening rod, thereby preventing the raw materials from being compacted and blocked at the bottom of the feed hopper due to vibration, and at the same time increasing the vibration amplitude of the feed hopper, ensuring that the raw materials for preparing powder coatings are stably put into the processing body, and improving the stability of the device; it includes a processing body and a feed hopper, an opening is provided in the middle of the top of the processing body, the bottom of the feed hopper extends into the processing body, and the feed hopper is slidably connected to the processing body, and is characterized in that it also includes a vibration mechanism, two groups of fixed plates, a top plate, a fixed rod and multiple groups of loosening rods, the vibration mechanism is installed on the processing body, the vibration mechanism is used to drive the feed hopper to vibrate up and down, and the two groups of fixed plates are symmetrically fixed on the left and right sides of the top of the processing body.

[0004] However, the above technical solution still has the following deficiencies in practical application: When powder is added to the reactor through the feed hopper, the position of the feed hopper is relatively fixed relative to the reactor, so the powder will only accumulate in a fixed area inside the reactor. When the powder accumulates in the same place, the stirring paddle needs to spend more time to disperse the accumulated powder and mix it with the surrounding liquid or other ingredients, which greatly affects the stirring efficiency. In addition, when the powder is added to the reactor, the powder will fall directly into the reactor, which makes it inconvenient to accurately control the feeding amount and feeding timing of each powder, which also affects the subsequent reaction effect.

[0016] The beneficial effects of the present invention are as follows: 1. A powder feeding device for water-based paint production according to the present invention utilizes an adjustable elastic material receiving assembly. When multiple powders need to be added to a reactor, multiple feed shells can be evenly distributed above the reactor according to the diameter of the reactor. Multiple powders will be evenly added from above the reactor and evenly distributed inside the reactor. When the stirring paddle rotates, it is easier to mix multiple powders, thereby avoiding the situation where powders accumulate in a fixed area inside the reactor and reduce stirring efficiency. In addition, when the spacing between adjacent feed shells changes, the spacing between multiple hoppers remains unchanged, making the feeding operation more convenient. On this basis, the feeding timing and single feed amount of the powder can be controlled according to actual needs, which is conducive to improving the subsequent reaction effect. Compared with the intermittent addition of powder and the control of the feeding amount using a solenoid valve, this method does not require repeated start and stop of the solenoid valve, and is therefore not prone to malfunction.

[0017] 2. The powder feeding device for water-based paint production described in the present invention utilizes a discharge auxiliary component. Whenever the powder is discharged through the inner cavity of the telescopic plate and the guide plate, the push plate pushes the powder in the inner cavity of the guide plate and the telescopic plate, prompting the powder to move to the discharge port. At the same time, as the guide plate rotates, the powder at the discharge port will also fall off due to the scraping of the edge of the discharge shell, thereby effectively avoiding the situation where the powder is not completely discharged due to the stickiness of the powder when it is discharged through the inner cavity of the guide plate and the telescopic plate, thereby ensuring the accuracy of the single feeding amount of the powder.

[0018] 3. The powder feeding device for water-based paint production described in the present invention utilizes a deformation-adaptive beating component to promote the falling of powder in the inner cavity of the elastic tube, thereby avoiding the situation where the powder is not in a straight trajectory when falling through the inner cavity of the elastic tube due to the tilted state of the deformed elastic tube, and then the powder falls slowly or gets stuck, affecting the feeding efficiency. In addition, since the pressure plates 1 and 2 can adapt to the deformation of the elastic tube, the beating range is relatively wide, further improving the beating efficiency.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

The guide plates 19 are plugged and slidably connected with the telescopic plates 18. The upper end of the leftmost discharge shell 3 is connected and fixedly connected to the hard tube 34, and the upper ends of the remaining discharge shells 3 are connected and fixedly connected to the elastic tube 4. The upper ends of the hard tube 34 and the elastic tube 4 are connected and fixedly connected to the hopper 2, and the adjacent hoppers 2 are fixedly connected.

[0024] In this embodiment, Figure 1 、 Figure 4-Figure 6 、 Figures 8-11 As shown, one end of the slide rail 28 is slidably connected to the slider 11, and one end of the slider 11 is fixedly connected to the inclined slot plate 5. The inclined slot plate 5 is horizontally arranged with multiple inclined slots of different angles and lengths. Each inclined slot has a guide column 31 passing through it, and the guide column 31 is slidably connected to the inclined slot.

[0025] One end of the slider 11 is threadedly connected to a threaded rod 2 33 , both ends of the threaded rod 23 are rotatably set on the slide rail 28 , one end of the slide rail 28 is fixedly connected to a motor 6 32 , and the output end of the motor 6 32 is fixedly connected to one end of the threaded rod 2 33 .

[0026] A connecting rod four 23 is rotatably provided on one side of the telescopic plate 18, and a connecting rod three 21 is rotatably provided on one end of the connecting rod four 23. A fixed plate 20 is fixedly connected to one side of the inner cavity of the inner shell 35, and the middle part of the connecting rod three 21 is rotatably provided on the fixed plate 20. A motor three 22 is fixedly connected to one side of the fixed plate 20, and the output end of the motor three 22 is fixedly connected to the middle part of the connecting rod three 21.

[0027] A motor 5 29 is fixedly connected to the middle of the rear end surface of the blanking shell 3 , and the output end of the motor 5 29 is fixedly connected to one side of the inner shell 35 .

[0028] Specifically, in the prior art, when powder is added to the reactor through a feed hopper, the position of the feed hopper is relatively fixed relative to the reactor, so the powder will only accumulate in a fixed area inside the reactor. When the powder accumulates in the same place, the stirring paddle needs to spend more time to disperse the accumulated powder and mix it with the surrounding liquid or other components, which greatly affects the stirring efficiency. Moreover, when the powder is added to the reactor, the powder will fall directly into the reactor, which makes it inconvenient to accurately control the feeding amount and feeding timing of each powder, which also affects the subsequent reaction effect.

[0029] Therefore, in order to solve the above problems, when using this embodiment, the base 1 is set in a suitable position so that multiple discharge shells 3 are above the reactor, and the discharge shell 3 on the leftmost side is located at the edge area of the reactor cavity. Then, according to the diameter of the reactor and the type and quantity of powder to be added, the motor 6 32 is used to drive the threaded rod 2 33 to rotate, so that the slider 11 and the chute plate 5 move up and down. When the chute plate 5 moves, it will use its chute to drive the guide column 31 to move, and the sliding sleeve 30 slides on the slide rail 28. The distance between two adjacent sliding sleeves 30 changes, and the distance between two adjacent sliding sleeves 3 0 spacing is always the same, the material shell 3 moves horizontally, so that the material shells 3 of the same number as the type of powder are placed above the reactor, and, under the premise of ensuring that the material shells 3 of the same number as the type of powder are placed above the reactor, the spacing between two adjacent material shells 3 is expanded to the greatest extent, so that multiple material shells 3 are evenly distributed within the diameter range of the reactor, and, since all material shells 3 except the left side need to be moved, and multiple hoppers 2 are fixed together, the elastic tube 4 will be deformed due to the movement of the lower end, and then multiple powders are added to different hoppers 2 respectively, and some The powder falls into the guide plate 19 and the telescopic plate 18 after passing through the hard tube 34 and the elastic tube 4, and then the motor 5 29 drives the inner shell 35 to rotate. When the inner shell 35 rotates, the powder above the opening of the inner shell 35 will be blocked by the edge of the discharge shell 3 and stay in the hard tube 34 and the elastic tube 4, and placed on the outer wall surface of the inner shell 35. When the telescopic plate 18 moves to the discharge port 17 below the discharge shell 3, the powder will fall into the reactor under the action of gravity, and then repeat the above operation. When the guide plate 19 and the telescopic plate 18 move to the discharge port 17 above the discharge shell 3 again, the powder It will fall into the guide plate 19 and the telescopic plate 18 again, and the above operation can be repeated to continuously add the powder into the reactor. Since multiple discharge shells 3 are evenly distributed above the reactor at equal distances, multiple powders will also be evenly added from above the reactor and distributed inside the reactor. When the stirring paddle rotates, it is easier to mix the multiple powders, thereby avoiding the situation where the mixing efficiency is reduced due to the accumulation of powders in a fixed area inside the reactor when multiple powders are added to the reactor. Moreover, when the distance between adjacent discharge shells 3 changes, the distance between multiple hoppers 2 remains unchanged, making the feeding operation more convenient.

[0030] Furthermore, since the powder is alternately received by the two guide plates 19 and the telescopic plate 18 and poured into the reactor, the feeding frequency of the powder can be controlled by controlling the rotation speed of the inner shell 35, and the connecting rod four 23 can be rotated by the motor three 22 driving the connecting rod three 21 to rotate, driving the telescopic plate 18 to slide on the guide plate 19, and the volume of the powder that can be accommodated by the telescopic plate 18 and the guide plate 19 can be adjusted. Therefore, through the above method, the feeding timing and the single feeding amount of the powder can be controlled according to actual needs, which is beneficial to improving the subsequent reaction effect. Moreover, compared with the use of a solenoid valve to achieve intermittent addition of powder and control of the feeding amount, this method does not require repeated starting and stopping of the solenoid valve and is not prone to malfunction.

[0031] In this embodiment, Figure 6 and Figure 7 As shown, the telescopic plate 18 is also provided with a discharging auxiliary component; The discharging auxiliary assembly includes two slide rods 27 slidably connected to one side of the telescopic plate 18 , and one end of the slide rod 27 is fixedly connected to a push plate 36 , which is located in the inner cavity of the telescopic plate 18 .

[0032] One end of the sliding rod 27 is fixedly connected to a threaded plate 26, one side of the threaded plate 26 is threadedly connected to a threaded rod 25, one end of the threaded rod 25 is rotatably set on the telescopic plate 18, one side of the telescopic plate 18 is fixedly connected to a motor 4 24, and the output end of the motor 4 24 is fixedly connected to one end of the threaded rod 25.

[0033] Specifically, in the above embodiment, although the powder can be first collected by the guide plate 19 and the telescopic plate 18 and then poured into the reactor, in some cases, the powder may be sticky. Therefore, when the powder is discharged from the inner cavity of the guide plate 19 and the telescopic plate 18, the discharge may not be complete, thereby affecting the single feeding amount. Therefore, in order to solve the above problems, whenever the powder is discharged through the inner cavity of the telescopic plate 18 and the guide plate 19, the motor four 24 drives the threaded rod 1 25 to rotate, so that the threaded plate 26 and the slide rod 27 move, and the push plate 36 pushes the powder in the inner cavity of the guide plate 19 and the telescopic plate 18, prompting the powder to move to the discharge port 17. At the same time, as the guide plate 19 rotates, the powder at the discharge port 17 will also fall off due to the scraping of the edge of the discharge shell 3, thereby effectively avoiding the situation where the powder is not completely discharged due to the viscosity of the powder when it is discharged through the inner cavity of the guide plate 19 and the telescopic plate 18, thereby ensuring the accuracy of the single feeding amount of the powder.

[0034] In this embodiment, Figure 2 and Figure 3 As shown, the blanking shell 3 is also provided with a deformation-adaptive material-beating component; The deformation-adaptive material-beating component includes a flip plate 6 rotatably arranged on one side of the upper end of the blanking shell 3, and sliding columns 8 are slidably connected on both sides of the flip plate 6. One end of the sliding column 8 is fixedly connected to a pressure plate 2 9, and a pressure plate 1 7 is inserted and slidably connected to the inner side of the pressure plate 2 9.

[0035] One side of the upper end of the blanking shell 3 is fixedly connected to a motor 10, and the output end of the motor 10 is fixedly connected to one end of the flip plate 6. A spring 12 is sleeved on one side of the sliding column 8, one end of the spring 12 is fixedly connected to the flip plate 6, and the other end is fixedly connected to the pressure plate 2 9. An eccentric block 13 is rotatably provided on one side of the flip plate 6, and one side of the flip plate 6 is fixedly connected to a motor 2 14, and the output end of the motor 2 14 is fixedly connected to the eccentric block 13, and the eccentric block 13 is in contact with the surface of one side of the pressure plate 2 9.

[0036] A connecting rod 2 16 is rotatably provided on one side of the pressure plate 2 9, and a connecting rod 15 is rotatably provided on one end of the connecting rod 2 16. One end of the connecting rod 15 is rotatably connected to one side of the pressure plate 1 7. A motor 7 37 is fixedly connected to one side of the pressure plate 2 9, and the output end of the motor 7 37 is fixedly connected to one end of the connecting rod 2 16.

[0037] Specifically, in the above embodiment, although the elastic tube 4 can adapt to the change in the orientation of the discharge shell 3 through elastic deformation, when the elastic tube 4 is deformed, the elastic tube 4 will be tilted. When the powder falls through the inner cavity of the elastic tube 4, its falling trajectory is not straight, which may cause the powder to fall slowly or get stuck, thereby affecting the feeding efficiency. Therefore, in order to solve the above problems, when the present embodiment is in use, since the deformation degree of the elastic tube 4 depends on the moving distance of the blanking shell 3, when the elastic tube 4 is tilted, according to the tilt degree of the elastic tube 4, the motor 10 is used to drive the flip plate 6 to rotate, so that the pressing plate 1 7 and the pressing plate 2 9 are parallel to the left edge of the elastic tube 4, and then according to the deformation length of the elastic tube 4, the motor 7 37 is used to drive the connecting rod 2 16 to rotate, and with the cooperation of the connecting rod 15, the pressing plate 1 7 is made to slide on the pressing plate 2 9, and the total length of the pressing plate 1 7 and the pressing plate 2 9 is adjusted, and this length is equal to the length of the elastic tube 4 after stretching, and then the motor 2 1 is used to rotate the pressing plate 1 7 and the pressing plate 2 9. 4 drives the eccentric block 13 to rotate, and the eccentric block 13 continuously squeezes the pressing plate 2 9, and the pressing plate 2 9 recovers under the action of the spring 12, so that the pressing plates 1 and 2 can be used to beat one side of the elastic tube 4, causing the elastic tube 4 to vibrate, thereby promoting the powder in the inner cavity of the elastic tube 4 to fall, avoiding the situation that the elastic tube 4 is in an inclined state after deformation, resulting in the powder falling through the inner cavity of the elastic tube 4 having a non-straight trajectory, and then causing the powder to fall slowly or get stuck, thereby affecting the feeding efficiency. In addition, since the pressing plates 1 and 2 9 can adapt to the deformation of the elastic tube 4, the beating range is relatively wide, further improving the beating efficiency.

[0038] Working principle: The base 1 is set in a suitable position so that multiple blanking shells 3 are above the reactor, and the leftmost blanking shell 3 is located at the edge area of the reactor cavity. Then, according to the diameter of the reactor and the type and quantity of powder to be added, the motor 6 32 is used to drive the threaded rod 2 33 to rotate, so that the slider 11 and the chute plate 5 move up and down. When the chute plate 5 moves, it will use its chute to drive the guide column 31 to move, and the sliding sleeve 30 slides on the slide rail 28. The distance between the two adjacent sliding sleeves 30 changes, and the distance between the two adjacent sliding sleeves 30 is always the same, then the blanking shell 3 moves horizontally so that the same number of discharge shells 3 as the number of powder types are above the reactor. Moreover, under the premise of ensuring that the same number of discharge shells 3 as the number of powder types are above the reactor, the distance between two adjacent discharge shells 3 is expanded to the greatest extent so that multiple discharge shells 3 are evenly distributed within the diameter range of the reactor. Moreover, since all discharge shells 3 except the left side need to be moved and multiple hoppers 2 are fixed together, the elastic tube 4 will be deformed due to the movement of the lower end. Then, multiple powders are added to different hoppers 2 respectively, and some powders are discharged through the hard tube 34 and The elastic tube 4 then falls into the guide plate 19 and the telescopic plate 18, and then the motor 5 29 drives the inner shell 35 to rotate. When the inner shell 35 rotates, the powder above the opening of the inner shell 35 will be blocked by the edge of the discharge shell 3 and stay in the hard tube 34 and the elastic tube 4, and placed on the outer wall surface of the inner shell 35. When the telescopic plate 18 moves to the discharge port 17 below the discharge shell 3, the powder will fall into the reactor under the action of gravity, and then repeat the above operation. When the guide plate 19 and the telescopic plate 18 move to the discharge port 17 above the discharge shell 3 again, the powder will fall into the reactor again. By repeating the above operations in the guide plate 19 and the telescopic plate 18, the powder can be continuously added to the reactor. Since multiple discharge shells 3 are evenly distributed above the reactor at equal distances, multiple powders can also be evenly added from above the reactor and distributed inside the reactor. When the stirring paddle rotates, it is easier to mix the multiple powders, thereby avoiding the situation where the stirring efficiency is reduced due to the accumulation of powders in a fixed area inside the reactor when multiple powders are added to the reactor. Moreover, when the spacing between adjacent discharge shells 3 changes, the spacing between multiple hoppers 2 remains unchanged, making the feeding operation more convenient. Furthermore, since the powder is alternately received by the two guide plates 19 and the telescopic plate 18 and poured into the reactor, the feeding frequency of the powder can be controlled by controlling the rotation speed of the inner shell 35, and the connecting rod four 23 can be rotated by the motor three 22 driving the connecting rod three 21 to rotate, driving the telescopic plate 18 to slide on the guide plate 19, and the volume of the powder that can be accommodated by the telescopic plate 18 and the guide plate 19 can be adjusted. Therefore, through the above method, the feeding timing and the single feeding amount of the powder can be controlled according to actual needs, which is beneficial to improving the subsequent reaction effect. Moreover, compared with the use of a solenoid valve to achieve intermittent addition of powder and control of the feeding amount, this method does not require repeated starting and stopping of the solenoid valve and is not prone to malfunction.Whenever the powder is discharged through the inner cavity of the telescopic plate 18 and the guide plate 19, the motor four 24 drives the threaded rod one 25 to rotate, so that the threaded plate 26 and the slide rod 27 move, and the push plate 36 pushes the powder in the inner cavity of the guide plate 19 and the telescopic plate 18, prompting the powder to move to the discharge port 17. At the same time, as the guide plate 19 rotates, the powder at the discharge port 17 will also fall off due to the scraping of the edge of the discharge shell 3, thereby effectively avoiding the situation where the powder is not completely discharged due to the viscosity of the powder when it is discharged through the inner cavity of the guide plate 19 and the telescopic plate 18, thereby ensuring the accuracy of the single feeding amount of the powder. Since the deformation degree of the elastic tube 4 depends on the moving distance of the blanking shell 3, when the elastic tube 4 is tilted, according to the tilt degree of the elastic tube 4, the motor 10 is used to drive the flip plate 6 to rotate, so that the pressing plate 1 7 and the pressing plate 2 9 are parallel to the left edge of the elastic tube 4, and then according to the deformation length of the elastic tube 4, the motor 7 37 is used to drive the connecting rod 2 16 to rotate, and with the cooperation of the connecting rod 15, the pressing plate 1 7 is made to slide on the pressing plate 2 9, and the total length of the pressing plate 1 7 and the pressing plate 2 9 is adjusted, and this length is equal to the length of the elastic tube 4 after stretching, and then the eccentric block 13 is driven to rotate by the motor 2 14. The eccentric block 13 continuously squeezes the pressing plate 2 9, and the pressing plate 2 9 recovers under the action of the spring 12, so that the pressing plate 1 7 and the pressing plate 2 9 can be used to beat one side of the elastic tube 4, so that one side of the elastic tube 4 vibrates, thereby promoting the powder in the inner cavity of the elastic tube 4 to fall, avoiding the situation that the elastic tube 4 after deformation is in an inclined state, resulting in the powder falling through the inner cavity of the elastic tube 4 having a non-straight trajectory, and then the powder falling speed is slow or stuck, affecting the feeding efficiency. In addition, since the pressing plates 1 7 and the pressing plates 2 9 can adapt to the deformation of the elastic tube 4, the beating range is relatively wide, further improving the beating efficiency.
