Abstract
Description
Technical Field
[0001] The utility model relates to the field of paint slurry production, in particular to a thick coating paint slurry stirring device. Background Art
[0002] In the paint industry, the stirring and mixing of thick coating paint slurry is a key step, which is directly related to the product quality and production efficiency. After the traditional stirring device finishes stirring, a large amount of paint slurry often remains on the inner wall of the bin body and the blades. These residues are difficult to remove by manual cleaning and require a lot of time and effort for in-depth cleaning. This not only increases the labor intensity of workers, but also may not be thoroughly cleaned, affecting the quality of the paint slurry for the next stirring. Due to the difficult cleaning and long cleaning time, some paint slurry is often treated as waste after stirring, which not only causes waste of resources, but also increases the treatment cost. Content of the Utility Model
[0003] The utility model provides a thick coating paint slurry stirring device, which solves the problem that it is not convenient to clean the residual paint slurry inside the bin body in the prior art.
[0004] The technical solution of the utility model is realized as follows:
[0005] A thick coating paint slurry stirring device includes a bin body. A discharge port is arranged at the bottom of the bin body, and a valve is arranged at the discharge port. A top cover is arranged at the top of the bin body, and a driving motor is fixed on the top cover. The output shaft of the driving motor penetrates through the top cover, and the output shaft is connected with a driving rod. A plurality of blades are fixedly arranged in a circumferential and axial array on the side wall of the driving rod. A rotating groove is arranged at the upper part of the driving rod, and a scraping groove communicated with the rotating groove is arranged on the side wall of the driving rod. The center line of the scraping groove is parallel to the axis of the driving rod. The scraping groove is arranged between two adjacent blades. A scraping device is arranged at the bottom end of the top cover. The scraping device includes a scraping plate. The scraping plate is sleeved on the driving rod through a through hole. A guiding rod is fixed in the through hole, and the guiding rod can move along the scraping groove. A through groove for the blade to pass through is arranged on the scraping plate. When the guiding rod is placed in the scraping groove, the through grooves correspond to the blades one by one. Screws are screwed at both ends of the scraping plate. The top ends of the screws are rotationally connected with the top cover through screw motors, and the bottom ends of the screws are fixed with bearings. A positioning bin for accommodating the bearings is arranged at the bottom end inside the bin body.
[0006] Furthermore, the bottom of the bin body is a conical plate, the small end of the conical plate is far away from the bin body, the discharge port is arranged at the small end of the conical plate. A silica gel buffer plate is arranged at the bottom end of the scraping plate. The silica gel buffer plate is connected with a conical pushing plate. The small end of the pushing plate is close to the conical plate. Moving grooves are arranged on both the pushing plate and the silica gel buffer plate, and the moving grooves correspond to the through holes and the through grooves. The conical plate makes the paint slurry at the bottom of the bin body easier to concentrate towards the discharge port under the action of gravity, reducing the residual paint slurry and dead corners of the bin body.
[0007] Further, the circumference of the scraping plate abuts against the inner side wall of the bin through a bin silica gel strip. The bin silica gel strip can absorb vibrations to a certain extent, reduce the vibrations of the scraping plate during movement, and improve the smoothness of scraping the residual paint slurry on the side wall of the bin.
[0008] Further, the scraping groove is a T-shaped groove, the guide rod and the scraping groove are in clearance fit, the guide rod is hermetically connected to the scraping groove through a sliding sealing strip, and a transition angle is provided at the connection between the rotating groove and the scraping groove. Through the cooperation of the scraping groove and the guide rod, the stability and sealing performance of scraping are improved, and it also has the effect of facilitating installation and maintenance.
[0009] Further, the taper of the conical plate is 1:0.12, and the taper of the pushing plate is 1:0.06. The taper difference enables the edge of the pushing plate to come into contact with the conical plate preferentially, which helps to extrude and discharge the paint slurry on the conical plate and prevent the paint slurry from accumulating.
[0010] Further, two symmetrically arranged blade silica gel strips are provided in the through groove, and the two blade silica gel strips abut against each other. By providing the blade silica gel strips, it is convenient to scrape the residual paint slurry on the blades and reduce the friction between the blades and the scraping plate.
[0011] Further, chamfers are provided at both the upper and lower ends of the blade. Due to the reduction of the paint slurry adhesion area, the blade silica gel strips can more effectively scrape the residual paint slurry, improving the cleaning efficiency and the maintenance convenience of the equipment.
[0012] Beneficial effects that can be produced by this technical solution.
[0013] By the cooperation of the scraping plate and the blades, the present utility model can quickly and effectively remove the residual paint slurry on the inner wall of the bin and the blades after the stirring is completed, reduce the difficulty and time of manual cleaning, reduce the cleaning time of the bin when frequently replacing the stirred materials, and can also maximize the recycling of the paint slurry and reduce the waste of the paint slurry. Through the cooperation of the conical plate and the pushing plate, the bottom of the bin gradually shrinks to the discharge port, reducing the residual paint slurry at the bottom of the bin, and the taper difference between the conical plate and the pushing plate helps to extrude and discharge the paint slurry on the conical plate to prevent the paint slurry from accumulating.

Detailed implementation manners
[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of 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.
[0025] As Figures 1-5As shown in the figure, the utility model provides a thick coating paint slurry stirring device, which includes a bin body 1. A discharge port 2 is provided at the bottom of the bin body 1, and a valve is provided at the discharge port 2. A top cover 3 is provided at the top end of the bin body 1. A driving motor 4 is fixed on the top cover 3. The output shaft of the driving motor 4 penetrates through the top cover 3, and the output shaft is connected to a driving rod 5. A plurality of blades 6 are fixedly arranged in a circumferential and axial array on the side wall of the driving rod 5. A rotating groove 7 is provided at the upper part of the driving rod 5, and a scraping groove 8 communicating with the rotating groove 7 is provided on the side wall of the driving rod 5. The center line of the scraping groove 8 is parallel to the axis of the driving rod 5. The scraping groove 8 is arranged between two adjacent blades 6. A scraping device is provided at the bottom end of the top cover 3. The scraping device includes a scraper 9. The scraper 9 is sleeved on the driving rod 5 through a through hole 10. A guiding rod 11 is fixed in the through hole 10. The guiding rod 11 can move along the scraping groove 8. A through slot 12 for the blade 6 to pass through is provided on the scraper 9. When the guiding rod 11 is placed in the scraping groove 8, the through slots 12 correspond to the blades 6 one by one. Screw rods 13 are screwed at both ends of the scraper 9. The top ends of the screw rods 13 are rotationally connected to the top cover 3 through screw rod motors. The bottom ends of the screw rods 13 are fixed with bearings 14. A positioning bin 15 for accommodating the bearings 14 is provided at the bottom end inside the bin body 1. The bin body 1 and the top cover 3 are snap-connected by a buckle.
[0026] During the use process, the synchronous rotation of the screw rods 13 places the scraper 9 in the rotating groove 7. At this time, the driving motor 4 drives the blades 6 through the driving rod 5 to fully stir the paint slurry. When the stirring is completed and the paint slurry needs to be discharged from the bin body 1, the screw rods 13 drive the scraper 9 synchronously again, so that the scraper 9 moves towards the bottom of the bin body 1. When the guiding rod 11 of the scraper 9 needs to enter the scraping groove 8, by slowly rotating the driving motor 4 and cooperating with the screw rods 13 to provide a downward thrust for the guiding rod 11 through the scraper 9, when the scraping groove 8 rotates to the lower side of the guiding rod 11, the guiding rod 11 can directly enter the scraping groove 8. Through the cooperation of the guiding rod 11 and the scraping groove 8, the blades 6 can be made to correspond to the through slots 12. During the downward movement of the scraper 9, the scraper 9 can scrape off the paint slurry on the surface of the blades 6 and the inner wall of the bin body 1, thereby reducing the adhesion of the paint slurry, reducing the difficulty of subsequent cleaning work, and reducing the waste of the paint slurry. By providing the bearings 14 and the positioning bin 15, support can be provided for the screw rods 13, preventing the screw rods 13 from tilting and causing the scraper 9 to get stuck, and improving the durability and stability of the equipment. After the stirring is completed, the scraper 9 scrapes off the paint slurry on the surface of the blades 6 and the inner wall of the bin body 1, which not only reduces the adhesion and waste of the paint slurry, avoids cross-contamination between different batches of paint slurry, ensures the consistency and quality of the product, but also greatly reduces the difficulty and cost of subsequent cleaning work.
[0027] As Figures 1-6As shown, the bottom of the bin body 1 is a conical plate 16, the small end of the conical plate 16 is away from the bin body 1, the discharge port 2 is arranged at the small end of the conical plate 16, a silica gel buffer plate 17 is provided at the bottom end of the scraper 9, the silica gel buffer plate 17 is connected with a conical push plate 18, the small end of the push plate 18 is close to the conical plate 16, and movable grooves are provided on both the push plate 18 and the silica gel buffer plate 17, and the movable grooves correspond to the through holes 10 and the through grooves 12. The conical plate 16 makes the bottom of the bin body 1 gradually contract to the discharge port 2. This structure naturally guides the paint slurry to concentrate at the discharge port 2, reducing the residue of the paint slurry at the bottom of the bin body 1. With the scraping action of the scraper 9, it can further ensure that the paint slurry is completely discharged, reducing the waste of the paint slurry caused by incomplete discharging. When the scraper 9 cooperates with the conical push plate 18 to move downward, the silica gel buffer plate 17 can flexibly contact the conical plate 16, avoiding equipment damage caused by hard collision.
[0028] As Figure 4 , 6 shown, the circumference of the scraper 9 abuts against the inner side wall of the bin body 1 through the bin body silica gel strip 19. A circumferential fixing groove is provided on the circumference of the scraper 9, and the bin body silica gel strip 19 is placed in the circumferential fixing groove. By setting the circumferential fixing groove, it is convenient for the disassembly and installation of the bin body silica gel strip 19. The bin body silica gel strip 19 can closely fit the inner side wall of the bin body 1, so as to more effectively scrape the paint slurry attached to the wall surface. The silica gel strip serves as a buffer layer between the scraper 9 and the bin body 1, reducing the direct friction and collision between the two, avoiding scratches or damages on the inner side wall of the bin body 1 caused by long-term scraping, and thus prolonging the service life of the scraper 9 and the bin body 1. The bin body silica gel strip 19 as a buffer layer can also reduce the noise generated when the scraper 9 scrapes the paint slurry to a certain extent.
[0029] As Figure 5 , 7 , 8 shown, the scraping groove 8 is a T-shaped groove, the guide rod 11 and the scraping groove 8 are in clearance fit, the guide rod 11 is hermetically connected with the scraping groove 8 through a sliding sealing strip 20, and a transition angle 21 is provided at the connection between the rotating groove 7 and the scraping groove 8. The T-shaped groove can prevent the guide rod 11 from shaking in the scraping groove 8, ensuring the precise alignment of the through groove 12 and the blade 6 during the movement of the scraper 9, not only improving the scraping accuracy, but also ensuring the stability of the scraping process, and avoiding problems such as paint slurry residue or the scraper 9 being stuck caused by shaking. Through the sliding sealing strip 20, the sealing performance between the guide rod 11 and the scraping groove 8 can be improved, and it can prevent the paint slurry from leaking from the gap. By setting the transition angle 21, it is convenient for the docking of the guide rod 11 and the scraping groove 8. By the clearance fit between the guide rod 11 and the scraping groove 8, it is convenient to install the sliding sealing strip 20, reducing the requirement for the precision of the parts.
[0030] As Figure 4 , 6As shown, the taper of the conical plate 16 is 1:0.12, and the taper of the push plate 18 is 1:0.06. By setting the taper difference, the edge of the push plate 18 can come into contact with the conical plate 16 first, forming a gradually increasing extrusion force, so as to quickly and evenly extrude the paint slurry on the conical plate 16 to the discharge port 2, reducing the residue and accumulation of the paint slurry on the conical plate 16. Reducing the paint slurry residue makes the cleaning and maintenance work of the equipment simpler, reducing the maintenance cost and time.
[0031] As shown in FIGS. 4-6, two symmetrically arranged blade silicone strips 22 are provided in the through groove 12, and the two blade silicone strips 22 are in contact with each other. The blade silicone strip 22 can closely fit the surface of the blade 6, so as to more effectively scrape the paint slurry attached to the blade 6, and helps to prevent the paint slurry from leaking from the through groove 12, ensuring that there is no paint slurry residue in the cleaned bin 1. By regularly replacing the worn blade silicone strips 22, the continuous and efficient operation of the equipment can be ensured.
[0032] As Figure 7 , 8 As shown, chamfers 23 are provided at both the upper and lower ends of the blade 6. By setting the chamfers 23, the attachment area of the paint slurry at both the upper and lower ends of the blade 6 can be reduced. The chamfers 23 make the edges at both the upper and lower ends of the blade 6 smoother, reducing the accumulation and attachment of the paint slurry at these parts. When the blade silicone strip 22 scrapes past, the remaining paint slurry can be more easily scraped off, thus significantly improving the cleaning efficiency. The chamfers 23 can remove the sharp corners of the blade 6, making the edge of the blade 6 smoother and reducing the scratching of the blade silicone strip 22 by the sharp corners.
[0033] 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.
