Description

Technical Field

[0001] The utility model relates to the technical field of water-based paint batching equipment, in particular to a quantitative batching equipment for water-based paint additives. Background Art

[0002] During the production process of water-based paint, the precise proportioning and addition of additives are one of the key factors to ensure the stable quality and excellent performance of the final product. When traditional batching equipment conveys and adds additives, due to the viscous characteristics of the additives themselves, residues are likely to form on the inner wall of the pipeline. Over time, these residues will gradually solidify, not only blocking the pipeline and affecting the normal flow of additives, but also possibly causing imbalance in the additive proportioning, thereby affecting the final performance of the water-based paint. Content of the Utility Model

[0003] The utility model provides a quantitative batching equipment for water-based paint additives, which solves the problem of inaccurate measurement caused by residues of water-based paint additives remaining on the inner wall of the pipeline in the prior art.

[0004] The technical solution of the utility model is realized as follows:

[0005] A quantitative batching equipment for water-based paint additives includes a plurality of additive bins. The additive bins are connected to a mixing bin through material pipes. A valve is provided at one end of the material pipe close to the mixing bin. A one-way component slides in the material pipe above the valve. One end of the one-way component away from the mixing bin is fixed with a connecting rod. The connecting rod passes through the additive bin along the material pipe. The connecting rod is driven by a first driving device. The first driving device includes a support bin. A driving gear rotates at one end inside the support bin, and a chute is provided at the other end through which it passes. The axis of the chute is perpendicular to the axis of the connecting rod. A pressing rod slides in the chute. Both ends of the pressing rod outside the support bin are connected with telescopic rods. The telescopic rods are fixed to the support bin. A driven gear rotates on the pressing rod. The connecting rod passes between the driving gear and the driven gear. The driving gear is driven by a motor.

[0006] Furthermore, the one-way component is a bowl-shaped plate made of corrosion-resistant silica gel. The open end of the bowl-shaped plate is close to the mixing bin, and the open end can abut against the inner side wall of the material pipe. The bowl-shaped plate helps to automatically scrape off the residues on the inner wall of the material pipe during the process of pushing the additives into the mixing bin, thereby reducing the waste of additives and preventing pipeline blockage.

[0007] Further, both the first one-way plate and the second one-way plate include circular plates. A plurality of one-way holes are provided through the circular plates. Annular baffles are provided at both ends of the one-way holes. A one-way valve core slides between the baffles. A spring is provided between the one-way valve core and the baffle close to the mixing bin. A gap is provided between the one-way valve core and the side wall of the one-way hole. Since the one-way valve core always abuts against the top baffle in the normal state and forms a seal, it can effectively prevent the leakage of the auxiliary agent in the non-working state, ensuring the accuracy and efficiency of the auxiliary agent addition. By the natural fall of the one-way valve core under the action of gravity to contact or separate from the baffle, precise control of the flow rate of the auxiliary agent is achieved.

[0008] Further, the one-way assembly includes circular plates. A plurality of one-way holes are provided through the circular plates. Annular baffles are provided at both ends of the one-way holes. A one-way valve core slides between the baffles. A plurality of communication holes are provided in the circumferential direction at the lower part of the one-way hole. When the one-way valve core abuts against the baffle close to the mixing bin, the one-way hole is communicated with the mixing bin through the communication holes. The design structure of the whole one-way assembly is relatively simple, with fewer components, and is easy to manufacture and assemble.

[0009] Further, the one-way assembly includes a first one-way plate and a second one-way plate arranged in sequence along the material pipe. The first one-way plate is close to the mixing bin. A through hole for the connecting rod to pass through is provided on the second one-way plate. A sleeve is fixed on the second one-way plate. The sleeve is sleeved on the connecting rod. The sleeve is driven by a second driving device. The one-way holes of the first one-way plate and the second one-way plate are arranged staggeredly. Through the coordinated action of the first driving device and the second driving device, the flow rate of the auxiliary agent can be precisely controlled. The mutual cooperation of the two one-way assemblies can provide additional stability during the operation process, reduce errors caused by equipment vibration or the flow of the auxiliary agent, and contribute to ensuring the stability of the product quality and improving the production efficiency.

[0010] Further, an annular silica gel scraper is provided in the material pipe or the auxiliary agent bin. The connecting rod or the sleeve is arranged inside the silica gel scraper. By timely removing the residual auxiliary agent on the sleeve or the connecting rod, the silica gel scraper ensures the full utilization of the auxiliary agent and reduces the waste of the auxiliary agent caused by the residue.

[0011] Further, both the connecting rod and the sleeve can be metal shaped tubes. Since the metal shaped tubes can be adjusted and bent as needed, the installation process becomes simpler and faster.

[0012] Further, a viewing window and a scale are provided on the side wall of the material pipe. The design of the viewing window and the scale enables the operator to monitor the equipment and add the auxiliary agent more intuitively and conveniently, simplifies the operation process, and reduces the operation difficulty.

[0013] The beneficial effects that can be produced by this technical solution.

[0014] The utility model scrapes the inner wall of the material pipe while pushing the material through the one-way component, effectively preventing the residue and curing of the viscous additive on the pipe wall, reducing the problems of pipeline blockage and wear caused by the accumulation of residues, not only ensuring the accuracy of metering, but also reducing the workload of cleaning and maintenance. By precisely controlling the rotation angle and speed of the motor, the moving distance of the one-way component in the material pipe can be accurately controlled, thereby realizing the precise quantitative addition of the additive and helping to improve the product quality.

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0025] Embodiment 1

[0026] As Figure 1-4 shown, the present invention provides a quantitative batching device for water-based paint additives, which includes a plurality of additive bins 1. The additive bins 1 are connected to a mixing bin 3 through a material pipe 2. A valve 4 is provided at one end of the material pipe 2 close to the mixing bin 3. A one-way component slides in the material pipe 2 above the valve 4. One end of the one-way component away from the mixing bin 3 is fixed with a connecting rod 6. The connecting rod 6 passes through the additive bin 1 along the material pipe 2. The connecting rod 6 is driven by a first driving device 7. The first driving device 7 includes a support bin 8. A driving gear 9 rotates at one end in the support bin 8, and a chute 10 is provided through the other end. The axis of the chute 10 is perpendicular to the axis of the connecting rod 6. A pressing rod 11 slides in the chute 10. Both ends of the pressing rod 11 outside the support bin 8 are connected with telescopic rods 12. A driven gear 13 rotates on the pressing rod 11. The connecting rod 6 is arranged between the driving gear 9 and the driven gear 13. The driving gear 9 is driven by a motor.

[0027] When it is necessary to add additives to the mixing bin 3, the telescopic rod 12 is extended or retracted to make the driven gear 13 approach the driving gear 9 and clamp the connecting rod 6. The driving gear 9 is powered by a motor. When the driving gear 9 rotates, due to the frictional force between the teeth and the connecting rod 6, the connecting rod 6 can drive the one-way component to move along the axis of the material pipe 2. When the one-way component approaches the mixing bin 3, the valve 4 is opened and the additives are pushed into the mixing bin 3. When the one-way component moves away from the mixing bin 3, the valve 4 is closed. At the same time, the additives pass through the one-way component under the action of gravity and flow into the space between the one-way component and the valve 4. Since the one-way component will rub against the inner wall of the material pipe 2, the moving range of the one-way component is the volume of the added additives. By controlling the moving range of the one-way component with the motor, the effect of quantitatively adding additives to the mixing bin 3 can be achieved. When the one-way component pushes the additives into the mixing bin 3, it can scrape the inner wall of the material pipe 2 to prevent the problem that sticky additives remain on the inner wall of the material pipe 2 and cause inaccurate metering. The valve 4 can be an existing solenoid valve, which is convenient to realize the closing of the valve 4 and improve the operation efficiency. The telescopic rod 12 can be an existing electric push rod. By arranging electric push rods at both ends of the pressure rod 11, the force balance of the driven gear 13 can be ensured, the connecting rod 6 can be prevented from falling off, and different diameters of the connecting rod 6 can be adapted, improving the adaptability of the driving device and preventing the risk of jamming caused by uneven dimensions during the production of the pressure rod 11. The one-way component can adapt to additives with different viscosities, improving the adaptability of the device.

[0028] Preferably, as Figure 2 、 4 shown, the one-way component includes a first one-way plate 19 and a second one-way plate 20 arranged in sequence along the material pipe 2. The first one-way plate 19 is close to the mixing bin 3. The second one-way plate 20 is provided with a through hole 21 for the connecting rod 6 to pass through. A sleeve 22 is fixed on the second one-way plate 20. The sleeve 22 is sleeved on the connecting rod 6. The sleeve 22 is driven by a second driving device 23. The one-way holes 15 of the first one-way plate 19 and the second one-way plate 20 are arranged staggeredly.

[0029] During use, the first driving device 7 first controls the first one-way plate 19 to move towards the mixing bin 3. At this time, the first one-way plate 19 moves away from the second one-way plate 20 and generates a vacuum effect, sucking the auxiliary agent into the space between the first one-way plate 19 and the second one-way plate 20. Then, the second one-way plate 20 moves towards the mixing bin 3 and provides a push for the auxiliary agent, enabling the auxiliary agent to pass through a one-way component. When the second one-way plate 20 abuts against the first one-way plate 19, the second one-way plate 20 and the first one-way plate 19 are simultaneously controlled to move away from the mixing bin 3 for the next quantitative operation. Since the one-way holes 15 of the first one-way plate 19 and the second one-way plate 20 are staggered, and the second one-way plate 20 abuts against the first one-way plate 19, the auxiliary agent cannot pass through the one-way holes 15. At this time, the valve 4 can be in an always-open state, increasing the service life of the valve 4 and reducing maintenance. A suction force can be generated between the first one-way plate 19 and the second one-way plate 20, and the auxiliary agent and the air mixed therein will be blocked when the first one-way plate 19 and the second one-way plate 20 overlap. Therefore, during the process of the one-way component moving away from the mixing bin 3, the air mixed in the auxiliary agent will also move away from the one-way component, preventing the problem of measurement errors caused by air entry. Through the staggered arrangement and coordinated operation of the first one-way plate 19 and the second one-way plate 20, not only the accurate measurement and pushing of the auxiliary agent are realized, but also the problem of measurement errors caused by air mixing in the auxiliary agent is effectively solved through the alternating actions of the two one-way components. By precisely controlling the flow rate of the auxiliary agent and reducing air mixing, it helps to achieve a more stable and efficient auxiliary agent addition process, not only improving production efficiency but also ensuring product consistency and quality stability.

[0030] Preferably, as Figure 4 , 7As shown, the first one-way plate 19 and the second one-way plate 20 both include a circular plate 14, each of which is provided with a plurality of one-way holes 15, and an annular baffle 16 is provided at both ends of the one-way hole 15, and a one-way valve core 17 slides between the baffles 16, and a spring 18 is provided between the one-way valve core 17 and the baffle 16 close to the mixing chamber 3, and a gap is provided between the one-way valve core 17 and the side wall of the one-way hole 15. During use, the spring 18 provides support for the one-way valve core 17, so that the one-way valve core 17 always abuts against the baffle 16 at the top and forms a seal, and only when the circular plate 14 moves away from the mixing chamber 3, the one-way valve core 17 will be subjected to the pressure of the auxiliary agent and move away from the baffle 16 at the upper end, so that the auxiliary agent passes through the gap, reducing the problem of auxiliary agent leakage caused by poor sealing, and avoiding the reduction of sealing performance caused by wear. Since the one-way valve core 17 is in a sealed state under normal conditions, it helps to reduce the residual auxiliary agent in the one-way hole 15. The one-way valve core 17 can prevent the auxiliary agent from flowing back and remaining by quickly resetting the spring 18 and sealing the one-way hole 15, further improving the accuracy of quantitative batching and product quality. The one-way valve core 17 has a simple structure and is easy to disassemble and replace, which is convenient for regular maintenance and cleaning, and prolongs the service life of the equipment. The circular plate 14 is provided with a sliding sealing ring on its circumference, and the sliding sealing ring abuts against the inner wall of the material tube 2. By using the existing sliding sealing ring, the service life and sealing performance of the circular plate 14 can be improved.

[0031] Preferably, Figure 4 As shown, the material tube 2 or the additive bin 1 is provided with an annular silicone scraper 25, and the connecting rod 6 or the sleeve 22 is inserted into the silicone scraper 25. If the additive residue on the connecting rod 6 or the sleeve 22 is taken out of the additive bin 1 or the material tube 2, it may contaminate other production links or equipment, and even affect the quality of the final product. The silicone scraper 25 can effectively remove the additive residue on the sleeve 22 or the connecting rod 6, and prevent these residues from being taken out of the additive bin 1 or the material tube 2, which not only helps to keep the equipment clean, but also avoids the pollution and waste of the additive outside the equipment.

[0032] Preferably, the connecting rod 6 and the sleeve 22 can both be metal shaped tubes. The metal shaped tube has good flexibility and plasticity, and can be bent and adjusted according to the different shapes of the material tube 2, so as to adapt to various complex pipeline layouts and improve the adaptability of the device. The metal shaped tube has higher strength and rigidity than the hose or other flexible materials. When subjected to pressure and impact, the metal shaped tube can maintain its shape and function, and is not easy to deform or damage, thereby enhancing the structural stability of the entire device.

[0033] Preferably, Figure 2As shown, a viewing window 26 and graduations 27 are provided on the side wall of the material pipe 2. The introduction of the viewing window 26 enables the operator to directly observe the flow of the auxiliary agent inside the material pipe 2, thereby monitoring the operating state of the equipment in real time, helping to promptly detect and handle equipment failures or abnormal conditions such as blockages and leaks, and avoiding production interruptions and losses. The setting of the graduations 27 enables the operator to accurately measure and check the amount of the added auxiliary agent, ensuring that the auxiliary agent is added according to the preset ratio and value, thereby improving the stability and consistency of the product.

[0034] Example 2

[0035] As Figure 6 As shown, the one-way component includes a circular plate 14. A plurality of one-way holes 15 are provided through the circular plate 14. Annular baffles 16 are provided at both ends of the one-way holes 15. A one-way valve core 17 slides between the baffles 16. A plurality of communication holes 24 are provided in the circumferential direction at the lower part of the one-way holes 15. When the one-way valve core 17 abuts against the baffle 16 close to the mixing chamber 3, the one-way holes 15 are communicated with the mixing chamber 3 through the communication holes 24. When the one-way component pushes the auxiliary agent into the mixing chamber 3, the auxiliary agent between the one-way component and the valve 4 provides support for the one-way valve core 17, making the one-way component sealed, effectively preventing the backflow of the auxiliary agent, and improving the accuracy of quantitative batching. During the process of the one-way component moving away from the valve 4 and when it is stationary, the one-way valve core 17 will, under the action of gravity, connect the one-way holes 15 and the communication holes 24 and allow the auxiliary agent to pass through. The one-way valve core 17 can be a sphere, and the sphere has a smooth surface and a small contact area, so the resistance when the auxiliary agent passes through is small, achieving the effect of adapting to auxiliary agents with different viscosities. The design structure of the entire one-way component is relatively simple, with a small number of components, easy to manufacture and assemble, and at the same time having the beneficial effects of being easy to clean and maintain. In this example, there is one one-way component when implemented.

[0036] Example 3

[0037] As Figure 5As shown, the one-way component is a bowl-shaped plate 5 made of corrosion-resistant silica gel. The open end of the bowl-shaped plate 5 is close to the mixing bin 3 and can abut against the inner wall of the material pipe 2. When the bowl-shaped plate 5 pushes the auxiliary agent into the mixing bin 3, the auxiliary agent between the bowl-shaped plate 5 and the valve 4 will provide a reverse supporting force for the bowl-shaped plate 5, so that the open end of the bowl-shaped plate 5 always abuts against the inner wall of the material pipe 2 and forms a seal. When the bowl-shaped plate 5 moves away from the valve 4, when there is no auxiliary agent to provide a supporting force for the bowl-shaped plate 5, the auxiliary agent on the side of the bowl-shaped plate 5 away from the mixing bin 3 will squeeze the bowl-shaped plate 5, causing a gap between the open end and the inner wall of the material pipe 2. The gap allows the auxiliary agent to pass through, and the next quantitative addition operation can be carried out. By precisely controlling the addition amount of the auxiliary agent, the quality stability of the final product can be ensured, and the overall quality of the product can be improved. The structure of the bowl-shaped plate 5 is simple, reducing the number of moving parts, thereby reducing the failure rate and maintenance cost. The corrosion-resistant silica gel material enables the bowl-shaped plate 5 to maintain stable performance during long-term use and is also convenient for cleaning and maintenance. In this embodiment, there is one one-way component when implemented.

[0038] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
