Description

Technical Field

[0001] This invention relates to the field of waterproof coating production and processing, and in particular to a production and processing equipment for polyurethane waterproof coatings. Background Technology

[0002] Polyurethane waterproof coating is a type of high-molecular elastic waterproof coating formulated with polyurethane prepolymer as the main film-forming substance and fillers, additives, etc. After being applied to the substrate surface, it cures through a chemical reaction to form a continuous, seamless, highly elastic waterproof film, thereby achieving waterproof, seepage-proof, and moisture-proof functions.

[0003] Due to the extremely high viscosity and poor flowability of polyurethane systems, its production and processing typically require the addition of various components, including large amounts of inorganic fillers such as heavy calcium carbonate, talc, and quartz powder. The resulting powder is fine and easily absorbs moisture. When this powder encounters a high-viscosity prepolymer, it is instantly encapsulated into dry clumps, forming an external film while the internal dry powder remains trapped. Furthermore, the high-viscosity material cannot be properly mixed at the bottom, sidewalls, or in dead corners, leading to powder settling and clumping. This results in low mixing efficiency and poor performance. Therefore, a production and processing equipment for polyurethane waterproof coatings is proposed. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, this invention proposes a production and processing equipment for polyurethane waterproof coatings, which can quickly and efficiently stir various raw material components added during the processing of polyurethane waterproof coatings, and can also prevent lumps from sticking to the bottom or side walls of the equipment, thereby improving the stirring quality.

[0005] To solve the above-mentioned technical problems, the basic technical solution proposed by this invention is as follows: A production and processing equipment for polyurethane waterproof coating includes a mixing drum, a drive motor mounted on the mixing drum, and a telescopic component connected to the lower output end of the drive motor. A shaft coaxial with the mixing drum is connected to the lower output end of the telescopic component. Main stirring paddles are arrayed at both the upper and lower ends of the outer side of the shaft. A stirring frame is slidably fitted on the main stirring paddles along the radial direction of the shaft. Multiple slide openings are arrayed at both the upper and lower ends of the outer side of the shaft. Threaded rings are slidably fitted on both the upper and lower sides of the shaft. The outer side of each threaded ring slides through each slide opening and extends to the outside of the shaft. A secondary stirring paddle is connected to the outer extension end. A drive assembly is provided inside the shaft. The drive assembly is used to drive the upper and lower threaded rings to move the secondary stirring paddles connected to their respective outer arrays away from each other and simultaneously push the stirring frame to slide away from the shaft along the radial direction of the shaft. The bottom of the mixing drum is fitted with a turntable, and the turntable is connected to two radial sides for scraping the inner wall of the mixing drum. A linkage assembly is provided at the lower end of the shaft, which drives the turntable to rotate synchronously when the shaft rotates. Each mixing frame is rotatably connected to two sides of the shaft, and a scraper is connected to the shaft for scraping the inner wall of the mixing drum. The mixing frame is also provided with a flipping assembly, which drives the scraper to rotate from a direction tangential to the circumferential rotation stroke to fit against the inner wall of the mixing drum as the mixing frame slides radially away from the shaft and approaches the inner wall of the mixing drum, so as to scrape off the clumps of material on the inner wall of the mixing drum.

[0006] Preferably, a mounting base is installed on one side of the mixing drum, the drive motor is installed at the lower end of the mounting base, a support is installed at the bottom of the mixing drum, and a discharge flange port is opened at the bottom of the mixing drum.

[0007] Preferably, each of the main stirring blades is provided with a retaining groove, and the stirring frame is slidably fitted on the main stirring blade through the retaining groove, extending to the end of the main stirring blade away from the shaft cylinder.

[0008] Preferably, the drive assembly includes a servo motor and a bidirectional lead screw. The servo motor is mounted on the upper inner wall of the shaft cylinder. The upper end of the bidirectional lead screw is mounted on the lower output end of the servo motor, and the lower end of the bidirectional lead screw is rotatably mounted on the lower inner wall of the shaft cylinder. The upper and lower threaded rings are respectively symmetrically threaded on the upper and lower ends of the outer side of the bidirectional lead screw. Each auxiliary stirring blade is rotatably connected to the adjacent main stirring blade by a rotating plate.

[0009] Preferably, a sealed motor compartment is provided at the upper end of the shaft cylinder, and the servo motor is installed in the sealed motor compartment. The output end of the servo motor rotates through the sealed motor compartment and extends into the shaft cylinder, and is connected to the upper end of the bidirectional lead screw. The upper and lower end surfaces of the bidirectional lead screw in the shaft cylinder have opposite thread directions, and the upper and lower threaded rings are respectively symmetrically threaded on the surfaces of the upper and lower end threads of the bidirectional lead screw with opposite thread directions.

[0010] Preferably, the linkage component includes a square sleeve rod and a square sleeve. The square sleeve rod is connected to the upper end of the turntable and is located in the axial direction of the turntable. The square sleeve is coaxially connected to the lower end of the shaft cylinder. The upper end of the square sleeve rod extends into the square sleeve and is slidably fitted along the axial direction of the square sleeve.

[0011] Preferably, the flipping assembly includes a gear, a slide, and a rack. The gear is fitted onto the upper and lower ends of the shaft. The slide is slidably connected to the end of the stirring frame away from the shaft. The rack is connected to both sides of the slide and is located between the shaft and the gear on both sides of the same stirring frame. The racks on both sides mesh with the gears on the sides away from each other.

[0012] Preferably, both sides of the stirring frame are connected to a mounting base, the shaft is rotatably mounted in the mounting base, the upper and lower sides of the stirring frame are connected to a mounting base, a limiting slide rod is slidably mounted on the slide block and mounted in the mounting base, a spring is mounted on the outside of the limiting slide rod between the slide block and the mounting base, and rollers that are rotatably connected to the inner wall of the stirring drum are rotatably mounted on the upper and lower ends of the slide block away from the stirring frame.

[0013] The beneficial effects of this invention are: 1. The technical solution of this invention uses a drive motor to rotate the shaft cylinder, which in turn drives the main stirring paddles connected in an array at the upper and lower ends of the shaft cylinder to rotate. This allows for the stirring of various raw materials during the production and processing of polyurethane waterproof coatings. Simultaneously, it controls the extension and retraction of the telescopic components to adjust the vertical position of the shaft cylinder within the mixing drum, achieving uniform stirring of the materials inside the mixing drum by tumbling them up and down. Furthermore, it controls the operation of a servo motor within the shaft cylinder to drive a bidirectional lead screw, which in turn causes the threaded rings on the upper and lower sides of the shaft cylinder to slide closer or further apart. When they slide further apart, the auxiliary stirring paddles connected in an array on the outer sides of the upper and lower threaded rings move away from each other and approach the main stirring paddles on the upper and lower sides. This also drives the rotating plate to rotate, pushing the stirring frame slidably mounted on the main stirring paddle to slide radially away from the shaft cylinder. This expansion of the stirring frame extends the range that the main stirring paddle can stir, increasing the stirring rate. Simultaneously, the sliding of the auxiliary stirring paddles connected in an array on the outer sides of the upper and lower threaded rings further tumbles the materials inside the mixing drum, further improving stirring efficiency. 2. The technical solution of this invention, through the rotation of the shaft, can drive the shafts and scrapers on each stirring frame to rotate with the shaft, so that each scraper can break up the agglomerated material along the tangential direction of its circumferential rotation stroke. At the same time, when the stirring frames are controlled to slide radially away from the shaft, the sliding seats on the stirring frames will gradually approach the inner wall of the stirring cylinder until the rollers on them are in contact with the inner wall of the stirring cylinder and form a rolling connection. Then the sliding seats will be pushed against and slide relative to the stirring frames, that is, slide radially towards the shaft on the stirring frames, thereby pushing the racks on both sides of the sliding seats to slide. Since the racks mesh with the gears mounted on the shaft, they will drive the shaft to rotate, thereby driving the scrapers on both sides to rotate from the original direction tangential to their rotation stroke towards the inner wall of the stirring cylinder, until they are in contact with the stirring cylinder. When the inner wall is in contact with the material, the stirring frame stops sliding. During the subsequent rotation and stirring process, the scraper removes any clumps adhering to the side wall of the stirring drum, breaking up the clumps and improving the stirring effect. Simultaneously, the rotation of the shaft also drives the lower square sleeve to rotate. Inside the square sleeve is a square rod, the lower end of which is connected to a turntable. This, in turn, drives the turntable and the scrapers on both sides to rotate, scraping the bottom of the stirring drum. The square sleeve and square rod are axially sliding, allowing for easy adjustment of the shaft height via a telescopic component. This adjusts the scraper's ability to thoroughly scrape the side wall of the stirring drum, while the bottom is scraped by the scraper, effectively preventing clumping and improving stirring efficiency and effect.

[0016] The following will be combined with the appendix Figure 1 To be continued Figure 6 The technical solutions in the embodiments of the present invention have been clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0017] Example 1: like Figures 1-6 As shown, this invention discloses a production and processing equipment for polyurethane waterproof coating, including a mixing drum 1, a drive motor 3 installed on the mixing drum 1, and a telescopic component 4 connected to the lower output end of the drive motor 3. A shaft 5 coaxial with the mixing drum 1 is connected to the lower output end of the telescopic component 4. Main stirring paddles 6 are arrayed and connected to the upper and lower ends of the outer side of the shaft 5. A stirring frame 12 is slidably sleeved on the main stirring paddle 6 along the radial direction of the shaft 5. Multiple slide openings 10 are arrayed and opened on the upper and lower ends of the outer side of the shaft 5. Threaded rings 13 are slidably sleeved on the upper and lower sides of the shaft 5. The outer side of each threaded ring 13 slides through each slide opening 10 and extends to the outside of the shaft 5. A secondary stirring paddle 14 is connected to the outer extension end. A drive assembly is provided inside the shaft 5. The drive assembly is used to drive the upper and lower threaded rings 13 to drive the secondary stirring paddles 14 connected to their respective outer arrays to slide away from each other, and simultaneously push the stirring frame 12 to slide away from the shaft 5 along the radial direction of the shaft 5. A turntable 26 is rotatably mounted at the bottom of the mixing drum 1, and scrapers 27 are connected to the radial sides of the turntable 26 to scrape against the inner wall of the mixing drum 1. A linkage assembly is provided at the lower end of the shaft cylinder 5. The linkage assembly is used to drive the turntable 26 to rotate synchronously when the shaft cylinder 5 rotates. Each mixing frame 12 is rotatably connected to both sides of the shaft rod 17. A scraper 18 is connected to the shaft rod 17 to scrape against the inner wall of the mixing drum 1. A flipping assembly is also provided on the mixing frame 12. The flipping assembly is used to drive the scraper 18 to rotate from the direction originally tangential to the circumferential rotation stroke to fit against the inner wall of the mixing drum 1 as the mixing frame 12 slides radially away from the shaft cylinder 5 and approaches the inner wall of the mixing drum 1, so as to scrape off the clumps of material on the inner wall of the mixing drum 1.

[0018] A mounting base 2 is installed on one side of the mixing drum 1, and a drive motor 3 is installed at the lower end of the mounting base 2. A support 30 is installed at the bottom of the mixing drum 1, and a discharge flange port 31 is opened at the bottom of the mixing drum 1 to facilitate direct discharge from the bottom.

[0019] Each main stirring paddle 6 is provided with a retaining groove 11. The stirring frame 12 is slidably fitted on the main stirring paddle 6 through the retaining groove 11 and extends to the end of the main stirring paddle 6 away from the shaft cylinder 5, so as to achieve stable sliding fit of the stirring frame 12.

[0020] Example 2: like Figures 1-6 As shown, the present invention discloses a production and processing equipment for polyurethane waterproof coating. Compared with Embodiment 1, this embodiment discloses the structure of the driving component.

[0021] The drive assembly includes a servo motor 8 and a bidirectional lead screw 9. The servo motor 8 is mounted on the upper inner wall of the shaft cylinder 5. The upper end of the bidirectional lead screw 9 is mounted on the lower output end of the servo motor 8, and the lower end of the bidirectional lead screw 9 is rotatably mounted on the lower inner wall of the shaft cylinder 5. The upper and lower threaded rings 13 are symmetrically threaded on the upper and lower ends of the outer side of the bidirectional lead screw 9. Each auxiliary stirring paddle 14 is rotatably connected to the adjacent main stirring paddle 6 by a rotating plate 15.

[0022] Furthermore, controlling the servo motor 8 can drive the bidirectional lead screw 9 to rotate, thereby driving the threaded rings 13 threaded at both ends of the outer side of the bidirectional lead screw 9 to move closer or further apart, and pushing the stirring frame 12 to slide on the main stirring paddle 6 through the rotating plate 15.

[0023] A sealed motor chamber 7 is provided at the upper end of the shaft cylinder 5. The servo motor 8 is installed in the sealed motor chamber 7. The output end of the servo motor 8 passes through the sealed motor chamber 7 and extends into the shaft cylinder 5, and is connected to the upper end of the bidirectional lead screw 9. The threads of the upper and lower end surfaces of the bidirectional lead screw 9 in the shaft cylinder 5 have opposite directions. The upper and lower threaded rings 13 are respectively symmetrically threaded on the surfaces of the upper and lower end threads of the bidirectional lead screw 9 with opposite directions.

[0024] This allows the drive motor 3 to rotate the shaft cylinder 5, which in turn rotates the main stirring paddles 6 arrayed at the upper and lower ends of the shaft cylinder 5. This stirs the raw materials during the production of polyurethane waterproof coatings. Simultaneously, it controls the extension and retraction of the telescopic component 4, adjusting the vertical position of the shaft cylinder 5 within the mixing drum 1 to achieve uniform stirring of the materials within the mixing drum 1. Furthermore, it controls the operation of the servo motor 8 within the shaft cylinder 5, driving the bidirectional lead screw 9 to rotate. This causes the threaded rings 13 on the upper and lower sides of the shaft cylinder 5 to slide closer or further apart. When they slide further apart, the upper and lower threaded rings... The auxiliary stirring paddles 14 connected to the outer array of the threaded ring 13 can move away from each other and approach the main stirring paddles 6 on the upper and lower sides respectively. At the same time, they can also drive the rotating plate 15 to rotate, pushing the stirring frame 12 slidably sleeved on the main stirring paddle 6 to slide radially away from the shaft cylinder 5. In this way, the range that the main stirring paddle 6 can stir can be extended by the expansion of the stirring frame 12, thereby increasing the stirring rate. At the same time, the sliding of the auxiliary stirring paddles 14 connected to the outer array of the upper and lower threaded rings 13 away from each other and the rotation around the shaft cylinder 5 can also tumble and stir the material in the stirring drum 1, further improving the stirring efficiency.

[0025] Example 3: like Figures 1-6 As shown, the present invention discloses a production and processing equipment for polyurethane waterproof coating. Compared with Embodiment 2, this embodiment discloses the structure of the linkage component.

[0026] The linkage assembly includes a square sleeve rod 28 and a square sleeve 29. The square sleeve rod 28 is connected to the upper end of the turntable 26 and is located in the axial direction of the turntable 26. The square sleeve 29 is coaxially connected to the lower end of the shaft cylinder 5. The upper end of the square sleeve rod 28 extends into the square sleeve 29 and is slidably sleeved along the axial direction of the square sleeve 29.

[0027] When the shaft cylinder 5 is driven to rotate, it can also drive the lower square sleeve 29 to rotate. The square sleeve 29 is fitted with a square sleeve rod 28, and the lower end of the square sleeve rod 28 is connected to a turntable 26. This can drive the turntable 26 and the scrapers 27 on both sides to rotate, scraping the bottom of the mixing drum 1. At the same time, the square sleeve 29 and the square sleeve rod 28 can be axially slidable, which makes it easy to adjust the height of the shaft cylinder 5 through the telescopic component 4, thereby adjusting the scraper 18 to scrape the side wall of the mixing drum 1. The bottom of the mixing drum 1 can be scraped by the scraper 27, effectively preventing the formation of clumps and improving the mixing efficiency and effect.

[0028] Example 4: like Figures 1-6 As shown, the present invention discloses a production and processing equipment for polyurethane waterproof coating. Compared with Embodiment 3, this embodiment discloses the structure of the flipping component.

[0029] The flipping assembly includes a gear 19, a slide 22, and a rack 23. The gear 19 is fitted on the upper and lower ends of the shaft 17. The slide 22 is slidably connected to the end of the stirring frame 12 away from the shaft cylinder 5. The rack 23 is connected to both sides of the slide 22 and is located between the shaft 17 and the gear 19 on both sides of the same stirring frame 12. The racks 23 on both sides mesh with the gears 19 on both sides away from each other.

[0030] Both sides of the stirring frame 12 are connected to the mounting base 16. The shaft 17 is rotatably mounted in the mounting base 16. Both the upper and lower sides of the stirring frame 12 are connected to the mounting base 20. The slide 22 is connected to the limiting slide rod 21 which is slidably mounted in the mounting base 20. The slide 22 and the mounting base 20 are connected to the spring 24 which is mounted on the outside of the limiting slide rod 21. The upper and lower ends of the slide 22 away from the stirring frame 12 are rotatably mounted with rollers 25 that are rotatably connected to the inner wall of the stirring drum 1.

[0031] This allows the rotation of the drive shaft cylinder 5 to drive the shaft rods 17 and scrapers 18 on each stirring frame 12 to rotate with the shaft cylinder 5. This enables each scraper 18 to break up agglomerated materials along the tangential direction of its circumferential rotation stroke. Simultaneously, when each stirring frame 12 slides radially away from the shaft cylinder 5, the sliding seat 22 on the stirring frame 12 will gradually approach the inner wall of the stirring cylinder 1 until the roller 25 on it comes into contact with the inner wall of the stirring cylinder 1 and forms a rolling connection. Consequently, the sliding seat 22 will be pushed against and slide relative to the stirring frame 12. The upper part slides radially towards the shaft cylinder 5, thereby pushing the racks 23 on both sides of the slide block 22 to slide. Since the racks 23 mesh with the gears 19 mounted on the shaft rod 17, the shaft rod 17 will be driven to rotate, thereby driving the scrapers 18 on both sides to rotate towards the inner wall of the mixing drum 1 from the original direction tangential to its rotation stroke, until they are in contact with the inner wall of the mixing drum 1 and the mixing frame 12 stops sliding. In the subsequent process of continuing to rotate and mix, the scrapers 18 can scrape off the clumps adhering to the side wall of the mixing drum 1 and break up the clumps, effectively improving the mixing effect.

[0032] Based on the disclosure and teachings of the foregoing specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the present invention should also fall within the protection scope of the claims of the present invention. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on the present invention.
