Description

Technical Field

[0001] The utility model relates to the technical field of water-based paint production equipment, in particular to a water-based paint production pretreatment processing equipment. Background Art

[0002] Water-based paint is a type of paint that uses water as a solvent or dispersion medium. It has the advantages of being environmentally friendly, safe, and energy-saving, and is therefore gradually replacing traditional solvent-based paint. The existing Chinese utility model patent with application number 202321338477.1 discloses a water-based paint pretreatment device, which uses a paint bucket and two motors to allow the paint to circulate between the two chambers of the paint bucket, thereby stirring the paint in various parts of the paint bucket. However, the above solution has the following problems: after the stirring is completed, the paint will remain on the bin body and the stirring device, which is inconvenient to clean the stirring device and the paint barrel, resulting in increased cleaning time. Utility Model Content

[0003] The utility model provides a water-based paint production pretreatment processing device, which solves the problem in the prior art that a stirring device cannot be easily and thoroughly cleaned.

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

[0005] A water-based paint production pretreatment processing equipment includes a warehouse body, a motor is provided on the warehouse body, a rotating shaft is passed through the warehouse body, the rotating shaft is driven by the motor, the rotating shaft is placed in the side wall of the warehouse body, and there is a circumferential array of receiving grooves, and a plurality of stirring rods are hinged in the receiving grooves. The stirring rods can be placed in the receiving grooves, and the stirring rods are connected to a driving device. A scraper is hinged on the end of the stirring rod away from the rotating shaft, and the end of the scraper close to the stirring rod is connected to the stirring rod through a tension spring. The scraper can be against the inner wall of the warehouse body, and a fixing device for supporting the rotating shaft is provided at the end of the rotating shaft outside the warehouse body.

[0006] Furthermore, the drive device includes a chute that coincides with the axis of the rotating shaft, a rack that slides within the chute, a bracket mounted at the top of the rotating shaft, a telescopic rod fixed to the bracket, the movable end of the telescopic rod fixedly connected to the rack, the axis of the telescopic rod coinciding with the axis of the rack, a drive compartment mounted within the receiving groove, the drive compartment communicating with the chute, a driven gear meshing with the rack within the drive compartment, a driven shaft fixed to the axis of the driven gear, both ends of the driven shaft extending through the drive compartment, and the driven shaft fixedly connected to the stirring rod. The meshing of the driven gear and the rack occurs within the drive compartment, effectively isolating the meshing components from the paint, preventing paint leakage and paint contamination and corrosion of the meshing components, extending the service life of the equipment, and reducing maintenance costs.

[0007] Furthermore, the fixing device includes a horizontal plate mounted on the rotating shaft via a bearing sleeve. The ends of the horizontal plate are connected to limit plates via vertical plates, with the limit plates both being spaced apart from the horizontal plate. Two arc-shaped L-shaped slots are arranged circumferentially on the side of the chamber body that abuts the rotating shaft, along which the limit plates can slide. The sliding of the limit plates along the L-shaped slots secures the rotating shaft, simplifying the installation process, improving installation efficiency, and enhancing the overall stability of the device.

[0008] Furthermore, the end of the L-shaped chute is connected to the top surface of the bin body through a locking hole. The limit plate is provided with a through hole corresponding to the locking hole. A locking shaft slides within the locking hole and passes through the locking hole and the through hole. The locking shaft cooperates with the locking hole and the through hole to prevent the limit plate from accidentally sliding due to vibration or external force, thereby further enhancing the stability of the shaft fixation.

[0009] Furthermore, an annular scraper ring is sleeved on one end of the rotating shaft placed in the bin body, and the scraper ring is fixed on the bin body. By timely cleaning the paint on the surface of the rotating shaft, the coating quality can be prevented from being affected by residual substances in subsequent operations.

[0010] Furthermore, the side wall of the chamber is connected to a vacuum pump via a vacuum tube, with a solenoid valve installed at the end of the vacuum tube near the chamber. Compared to traditional chemical defoamers or mechanical agitation defoaming methods, this method is more efficient and environmentally friendly. It not only quickly removes large bubbles from the paint, but also effectively treats microbubbles, improving the uniformity and quality of the paint.

[0011] Furthermore, a vibrator is provided on the side wall of the bin body. The vibration defoaming method is not limited by factors such as the type of coating, viscosity, temperature, etc. and has wide adaptability.

[0012] The beneficial effects that this technical solution can produce.

[0013] When the interior of the silo needs to be cleaned, the utility model first disconnects the fixing device, then uses the driving device to store the stirring rod and the hanging plate in the storage slot, and then easily pulls out the rotating shaft. In this way, the rotating shaft and the interior of the silo can be thoroughly cleaned separately, and the inconvenience of cleaning and space obstruction caused by the rotating shaft in the silo are effectively avoided. Through the cooperation of the scraper and the stirring rod, the side wall is carefully scraped, the agglomeration and deposition of the paint on the inner wall of the silo is reduced, the mixing uniformity and fluidity of the paint are improved, and the quality of the final product is guaranteed. The fixing device stabilizes the rotating shaft, ensures the stability of operation, and greatly simplifies the installation and disassembly process of the equipment, improving the overall convenience of operation and maintenance efficiency.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] like Figure 1-3As shown in Figure 5, the utility model provides a water-based paint production pretreatment processing equipment, including a warehouse body 1, a motor 2 is provided on the warehouse body 1, a rotating shaft 3 is passed through the warehouse body 1, the rotating shaft 3 is driven by the motor 2, the rotating shaft 3 is placed in the side wall of the warehouse body 1, and a circumferential array of receiving grooves 4 is provided, and a plurality of stirring rods 5 are hinged in the receiving grooves 4. The stirring rods 5 can be placed in the receiving grooves 4, and the stirring rods 5 are connected to a driving device. The end of the stirring rod 5 away from the rotating shaft 3 is hinged to a scraper 6, and the end of the scraper 6 close to the stirring rod 5 is connected to the stirring rod 5 through a tension spring 7. The scraper 6 can be against the inner wall of the warehouse body 1, and the end of the rotating shaft 3 placed outside the warehouse body 1 is provided with a fixing device for supporting the rotating shaft 3. The end of the rotating shaft 3 placed outside the warehouse body 1 is fixed with a driving gear, and the motor 2 is provided with a motor 2 gear meshing with the driving gear. The driving device can be a driving motor fixed in the stirring rod 5. Both the motor 2 and the driving motor are prior art.

[0024] During use, the rotating shaft 3, the stirring rod 5 and the scraper 6 are simultaneously inserted into the silo 1, and the gear of the motor 2 is meshed with the drive gear. The rotating shaft 3 is then supported by a fixing device to ensure the stable fixation of the rotating shaft 3, avoid equipment failure caused by the shaking of the rotating shaft 3, and improve the stability and reliability of the equipment. After the rotating shaft 3 is placed in the silo 1, the scraper 6 is moved close to the inner wall of the silo 1 under the elastic action of the tension spring 7, and the driving device drives the stirring rod 5 to adjust the angle. When the stirring rod 5 rotates to the appropriate angle, the rotating shaft 3 is driven by the motor 2 to rotate, and the stirring rod 5 and the scraper 6 simultaneously stir the paint in the silo 1. Through the simultaneous action of the stirring rod 5 and the scraper 6, the paint in the silo 1 can be effectively stirred, ensuring sufficient mixing of the paint, and improving production efficiency and product quality. When the stirring is finished and the warehouse body 1 needs to be cleaned, the fixing device is disconnected, and the stirring rod 5 is placed in the receiving groove 4 through the driving device. At this time, the hinge of the stirring rod 5 and the scraper 6 can be placed on the upper part of the receiving groove 4, and then the rotating shaft 3 is pulled out. During the withdrawal process, the warehouse body 1 will allow the scraper 6 to overcome the tension of the tension spring 7 and make the scraper 6 and the stirring rod 5 resist each other, so as to facilitate the withdrawal of the rotating shaft 3 from the warehouse body 1, and then the rotating shaft 3 and the inside of the warehouse body 1 can be cleaned separately. Figure 2 The stirring rod at the lower end of the rotating shaft should be considered as a schematic diagram of the position of the stirring rod during the retraction process.

[0025] like Figure 3 、 6As shown, the drive device includes a chute 8 that coincides with the axis of the rotating shaft 3. A rack 9 slides within the chute 8. A bracket 10 is provided at the top of the rotating shaft 3. A telescopic rod 11 is fixed to the bracket 10. The movable end of the telescopic rod 11 is fixedly connected to the rack 9. The axis of the telescopic rod 11 coincides with the axis of the rack 9. A drive compartment 12 is provided in the accommodating groove 4. The drive compartment 12 is connected to the chute 8. A driven gear 13 meshing with the rack 9 is provided in the drive compartment 12. A driven shaft 14 is fixed to the axis of the driven gear 13. Both ends of the driven shaft 14 pass through the drive compartment 12 and are fixedly connected to the stirring rod 5. The driven shaft 14 is rotatably sealed with the drive compartment 12. The telescopic rod 11 is an existing technology, such as an electric push rod or a hydraulic rod.

[0026] During use, the rack 9 slides along the chute 8, simultaneously driving multiple driven gears 13. The drive chamber 12 allows the driven gears 13 to mesh with the rack 9 in an environment isolated from the paint, helping to prevent paint leakage and any impact on the meshing parts, extending the device's service life. The device is also adaptable to paints of varying viscosities and concentrations, making it highly versatile. The rack 9 and the telescopic stem serve as separate drive sources, allowing multiple stirring rods 5 to be simultaneously adjusted in angle, saving energy. The telescopic rod 11 drives the rack 9 to extend and retract, ensuring that paints at different heights and in different areas are fully stirred, thereby improving product quality and increasing the device's flexibility and applicability. The telescopic rod 11 connects the rack 9, reducing the number and complexity of components within the chamber 1 and the risk of device failure due to paint erosion or wear. This also facilitates maintenance and component replacement, extending the device's service life. The drive chamber 12 separates the drive unit from the paint, allowing it to be adapted to paints of varying viscosities and concentrations, providing it with greater versatility.

[0027] like Figure 1 、 2As shown in Figure 4, the fixing device includes a horizontal plate 15, which is sleeved on the rotating shaft 3 through a bearing 16. The two ends of the horizontal plate are connected to a limit plate 17 through a vertical plate. The limit plates 17 are both away from the horizontal plate 15. There are two arc-shaped L-shaped grooves 18 in a circumferential array on the side of the warehouse body 1 that abuts the rotating shaft 3. The limit plate 17 can slide along the L-shaped groove 18. During the installation of the rotating shaft 3, the limit plate 17 is slid along the L-shaped groove 18. When the limit plate 17 moves to the end of the L-shaped groove 18, the rotating shaft 3 can be fixed by the friction between the L-shaped groove 18 and the limit plate 17. The cooperation of the limit plate 17 and the L-shaped groove 18 can limit the rotating shaft 3 to prevent vibration or other external forces from causing the rotating shaft 3 to be disengaged from the motor 2, ensuring the stability of the rotating shaft 3 during operation, thereby improving the reliability and safety of the equipment. When maintenance or removal of the shaft 3 is required, the shaft 3 can be easily released by sliding the limit plate 17 along the L-shaped slot 18, reducing maintenance difficulty and cost. The bearing 16 allows the shaft 3 to rotate more smoothly, reducing friction between the shaft 3 and the chamber 1, which not only reduces energy consumption but also extends the service life of the equipment.

[0028] like Figure 4 As shown, the end of the L-shaped chute 18 is connected to the top surface of the hopper body 1 via a locking hole 19. The limit plate 17 is provided with a through hole corresponding to the locking hole 19. A locking shaft 21 slides within the locking hole 19 and can pass through the locking hole 19 and the through hole. Before the limit plate 17 enters the end of the L-shaped chute 18, the locking shaft 21 needs to be pulled out first. Then, the limit plate 17 needs to be slid into the end of the L-shaped chute 18. After the locking hole 19 is aligned with the through hole, the locking shaft 21 is inserted into the locking hole 19 and the through hole. This not only secures the limit plate 17, but also ensures the stability of the rotating shaft 3 during operation and prevents the rotating shaft 3 from disengaging from the motor 2 due to vibration or other external forces, thereby improving the reliability and safety of the device. The locking action of the locking shaft 21 can reduce the wear of the limit plate 17 caused by frequent sliding at the end of the L-shaped chute 18, helping to extend the service life of the fixing device and reduce performance degradation or failure caused by wear.

[0029] like Figure 2 As shown, one end of the rotating shaft 3 placed in the warehouse body 1 is provided with an annular scraper ring 22, and the scraper ring 22 is fixed to the warehouse body 1. The scraper ring 22 can be used to scrape off the paint remaining on the surface of the rotating shaft 3 when the rotating shaft 3 is pulled out, thereby reducing the time for subsequent cleaning of the rotating shaft 3 and helping to improve production efficiency. When the rotating shaft 3 is inserted into the warehouse body 1, the scraper ring 22 can also prevent dust and other impurities attached to the surface of the rotating shaft 3 from entering the warehouse body 1, ensuring that no pollutants remain in the warehouse body 1. The scraper ring 22 allows some of the paint that is not completely attached to the target object to fall into the warehouse body 1 and be discharged from the warehouse body 1, so that the paint can participate in subsequent production, thereby further improving the utilization rate of the paint and reducing production costs.

[0030] like Figure 1 、 2 As shown, the side wall of the silo 1 is connected to a vacuum pump 23 via a vacuum tube. A solenoid valve 24 is installed at one end of the vacuum tube near the silo 1. Both the vacuum pump 23 and the solenoid valve 24 are conventional. The vacuum pump 23 creates a negative pressure environment within the silo 1, significantly reducing the air pressure within the silo 1. This accelerates the collapse and dissipation of bubbles in the paint, making the paint more uniform and stable, and improving the adhesion and durability of the coating. The solenoid valve 24 can be opened and closed quickly to prevent paint leakage.

[0031] like Figure 1 、 2 As shown, the side wall of the silo 1 is provided with a vibrator 25. The vibration of the vibrator 25 vibrates the silo 1 and the paint inside, accelerating the bursting and escape of bubbles, improving defoaming efficiency and contributing to increased production efficiency. Vibration defoaming can more comprehensively affect every part of the paint, including tiny bubbles that are difficult to reach with negative pressure or bubbles hidden deep in the paint. Therefore, combining the vibrator 25 with the vacuum pump 23 can further enhance the defoaming effect and ensure that bubbles in the paint are completely removed. The vibrator 25 can also prevent material from accumulating in the silo 1.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
