[0001] This utility model relates to the field of environmentally friendly polyurethane waterproof coating production and preparation technology, specifically to an environmentally friendly and efficient device for producing polyurethane waterproof coatings. Background Technology

[0002] Environmentally friendly polyurethane waterproof coatings possess excellent mechanical properties, good flexibility, and corrosion resistance, making them widely used in building waterproofing. The background technology primarily addresses the shortcomings of traditional waterproofing materials such as asphalt membranes, polyvinyl chloride (PVC) materials, and epoxy resins, including insufficient environmental performance, complex construction, and limited weather resistance. With the development of green building and increasingly stringent environmental regulations, the development of non-toxic, odorless, environmentally friendly, and safe waterproofing materials has become a key research focus in the industry. Polyurethane waterproof coatings, through optimized formulations, the use of low-VOC (volatile organic compound) raw materials, combined with a high-performance crosslinking system and good adhesion, achieve a dual improvement in environmental protection and waterproofing performance, gradually becoming an ideal choice for building waterproofing materials. Currently, the production process of environmentally friendly polyurethane waterproof coatings utilizes coating mixing technology. Due to the viscosity of the coating, it adheres to the inner wall or bottom of the coating mixing device, easily leading to severe wall adhesion and uneven mixing, affecting the final quality of the coating. Furthermore, severe wall adhesion makes subsequent removal or cleaning difficult, further reducing the efficiency and effectiveness of environmentally friendly and efficient polyurethane waterproof coating production equipment.

[0003] Therefore, it is necessary to develop an environmentally friendly and efficient equipment for producing polyurethane waterproof coatings. Utility Model Content

[0022] This utility model provides the following technical solution: a polyurethane waterproof coating device, please refer to... Figures 1-4 The system includes a base plate 1, with side frames 2 mounted on both sides of the top of the base plate 1. A rotating shaft 201 is rotatably connected to the upper part of one side outer wall of each side frame 2. A synchronous pulley 202 is mounted on the top of the rotating shaft 201 and is connected by a synchronous belt. A handwheel 203 is mounted on the bottom of one set of rotating shafts 201. The rotating shafts 201 are rotatably connected to one side of each of the two sets of side frames 2 on the base plate 1, and the synchronous pulleys 202 on the two sets of rotating shafts 201 are connected by a synchronous belt. By operating the handwheel 203 mounted on the bottom of one set of rotating shafts 201, the two sets of rotating shafts 201 can be rotated synchronously. A sealing cover 3 is mounted above the opposite side of each of the two sets of side frames 2. A movable seat 301 is mounted on the outer wall of each side of the sealing cover 3. The interior of 01 is threadedly connected to the outer wall of the rotating shaft 201. A motor A302 is installed at the top center of the sealing cover 3. A stirring shaft 303 is installed at the output end of the motor A302. A stirring paddle 304 is provided on the outer wall of the stirring shaft 303. A positioning seat 305 is installed at the bottom end of the stirring shaft 303. The two sets of moving seats 301 on the sealing cover 3 are threadedly connected to the outer walls of the two sets of rotating shafts 201, so that the rotating shafts 201 can rotate forward or backward, and can synchronously drive the sealing cover 3 to rise or fall. By installing the stirring shaft 303 at the output end of the motor A302 on the sealing cover 3 and installing multiple sets of stirring paddles 304 on the outer wall of the stirring shaft 303, the motor A302 can drive and control the stirring paddles 304 to rotate and stir.

[0023] An auxiliary component is installed below the sealing cap 3. This auxiliary component includes a paint tank 4. Connecting shafts 401 are installed on both outer walls of the paint tank 4. The outer walls of the connecting shafts 401 are rotatably connected to the interior of the side frame 2. A motor B402 is installed at one end of each connecting shaft 401. The motor B402 is fixed below one outer wall of the side frame 2. A shaft 403 is rotatably connected to the center of the bottom of the paint tank 4. A positioning groove 404 is provided at the center of the upper surface of the shaft 403. Moving plates 405 are provided on the outer walls of the shaft 403. A scraper A406 is provided at the bottom of the moving plate 405, and a scraper B407 is provided on one side of the top of the moving plate 405. The connecting shafts 401 on the paint tank 4 are rotatably connected between the two sets of side frames 2. The output end of the motor B402 on one set of side frames 2 is fixedly connected to the connecting shafts 401, allowing the motor B402 to drive and control the paint tank 4. The rotation operation is performed by installing four sets of moving plates 405 on the outer wall of the shaft 403 inside the paint tank 4, and setting scrapers A406 and B407 below and above the moving plates 405 respectively. Scraper A406 contacts the bottom of the paint tank 4, and scraper B407 contacts the inner wall of the paint tank 4, so that the positioning seat 305 on the stirring shaft 303 is connected to the positioning groove 404 on the shaft 403. This allows the motor A302 to drive and control the shaft 403 to rotate, forming multiple sets of stirring paddles 304 on the outer wall of the stirring shaft 303 to mix and stir the environmentally friendly polyurethane waterproof coating in the paint tank 4. Scrapers A406 and B407 scrape off the paint that sticks to the inner wall of the paint tank 4, ensuring the uniformity of the mixing of the environmentally friendly polyurethane waterproof coating and minimizing the possibility of uneven mixing due to partial adhesion of the environmentally friendly polyurethane waterproof coating, which would affect the final quality.

[0024] Working Principle: When using this utility model, the two sets of side frames 2 on the base plate 1 are rotatably connected to the rotating shafts 201 on one side, and the synchronous pulleys 202 on the two sets of rotating shafts 201 are synchronously connected by a synchronous belt. A handwheel 203 is installed at the bottom end of one set of rotating shafts 201, and operating the handwheel 203 can synchronously control the rotation of the two sets of rotating shafts 201. By setting the two sets of movable seats 301 on the sealing cover 3 in a threaded connection on the outer wall of the two sets of rotating shafts 201, the rotating shafts 201 can be rotated forward or backward, which can synchronously drive the sealing cover 3 to rise or fall. By installing the stirring shaft 303 at the output end of the motor A302 on the sealing cover 3, and installing multiple sets of stirring paddles 304 on the outer wall of the stirring shaft 303, the rotation of the two sets of rotating shafts 201 can be synchronously controlled. Motor A302 drives and controls the stirring paddle 304 to rotate and stir. The connecting shaft 401 on the paint tank 4 is rotatably connected between two sets of side frames 2. The output end of motor B402 on one set of side frames 2 is fixedly connected to the connecting shaft 401, allowing motor B402 to drive and control the rotation of the paint tank 4. Four sets of movable plates 405 are installed on the outer wall of the shaft 403 inside the paint tank 4. Scrapers A406 and B407 are correspondingly positioned below and above the movable plates 405. Scrapers A406 contact the bottom of the paint tank 4, and scrapers B407 contact the inner wall of the paint tank 4, ensuring that the positioning seat 305 on the stirring shaft 303 mates with the positioning groove 404 on the shaft 403. This allows motor A302 to drive and control shaft 403 to rotate, forming multiple sets of stirring paddles 304 on the outer wall of stirring shaft 303 to mix and stir the environmentally friendly polyurethane waterproof coating in paint tank 4. Scrapers A406 and B407 scrape off any coating adhering to the inner wall of paint tank 4, ensuring uniform mixing of the environmentally friendly polyurethane waterproof coating and minimizing unevenness caused by coating adhering to the wall, thus affecting the final quality. It also minimizes the difficulty in cleaning or removing adhering coating. The entire operation requires turning handwheel 203 to raise the sealing cap 3 to a certain height before adding the required amount of environmentally friendly polyurethane waterproof coating. The raw materials are then controlled to have their sealing cap 3 reset in the paint tank 4 until the positioning seat 305 is inserted into the positioning groove 404 on the shaft 403. The stirring paddle 304, scraper A406, and scraper B407 are rotated according to the drive of motor A302 until the mixture is completely stirred. Then, the sealing cap 3 is lifted, and motor B402 drives the paint tank 4 to tilt, completing the preparation of the environmentally friendly polyurethane waterproof coating. The tilted angle of the paint tank 4 also facilitates cleaning. After the paint tank 4 is cleaned, the reset scale needs to be set according to the angle of the moving plate 405. The reset scale marking needs to be specified before production to ensure that after the sealing cap 3 is sealed, the positioning seat 305 can be inserted into the positioning groove 404. Furthermore, to meet environmental protection requirements...It is also necessary to address the energy supply for motors A302 and B402 in the later stages. This will be achieved by utilizing existing solar and wind energy collection methods, which will contribute to environmental protection and effectively improve the performance and production efficiency of the environmentally friendly and efficient polyurethane waterproof coating production equipment.
