Embodiment
[0028] A phenolic molding compound mixer with a scraping function, comprising a frame 1. Both ends inside the frame 1 are fixedly installed with fixed columns 2. A push rod 3 is arranged inside one of the fixed columns 2. One end of the push rod 3 is threadedly installed with a connector 4 located outside the fixed column 2. An installation cavity 7 is opened on one side of the connector 4. A pin 5 is fixedly connected to one side of the inner cavity of the installation cavity 7. A scraper 6 sleeved on the pin 5 is inserted into the inner cavity of the installation cavity 7. Arc-shaped grooves 8 are opened on both sides of the bottom of the scraper 6. A positioning component adapted to the scraper 6 is arranged inside the connector 4.
[0029] The specific usage process is as follows: First, install the scraping plate 6. When installing, snap the protruding part at the top of the scraping plate 6 into the installation cavity 7, and at the same time, sleeve this protruding part onto the plug pin 5. During this process, after the scraping plate 6 is snapped into the connector 4, the end of the fixing pin 13 will also snap into the interior of the scraping plate 6 to fix the scraping plate 6 on the connector 4. The process is as follows: When the scraping plate 6 is snapped into the installation cavity 7, it will first push the fixing pin 13 upward, and at the same time, the fixing pin 13 will also stretch the spring 14. Then, after the jack on the scraping plate 6 is aligned with the fixing pin 13, under the action of the spring 14, the fixing pin 13 is pulled back and the end of the fixing pin 13 is inserted into the jack on the scraping plate 6, that is, inserted into the scraping plate 6. Finally, the scraping plate 6 is fixed on the connector 4 to ensure the stability of the scraping plate 6 during operation, and it is also convenient for the user to remove and replace the scraping plate 6. When replacing, simply pull out the scraping plate 6 with force, which provides convenience for the user's maintenance work. At this time, the assembly of the scraping plate 6 and the connector 4 is completed. Then, sleeve the clamping block 9 onto the push rod 3, and then install the end of the push rod 3 onto the connector 4 by means of threaded connection. Then, snap the clamping block 9 into the fixed column 2. In this way, the scraping plate 6 can be installed on the mixer, and arc-shaped grooves 8 that are fitted to the surface of the mixing roller member 15 are provided on both sides of the bottom of the scraping plate 6, so as to ensure that the surface of the mixing roller member 15 can be scraped clean. Among them, the clamping block 9 is clamped in the fixed column 2, so that the push rod 3 can be limited, ensuring that the push rod 3 can always move and work at a horizontal angle. During operation, the push rod 3 slides in the through hole 10, and it is also convenient for the user to remove and replace the push rod 3 and the scraping plate 6 for maintenance, providing convenience for the user's work. After that, when the machine is working, that is, when the mixing roller member 15 is working, specifically as follows: The stepping motor 17 is used to drive the mixing roller member 15 and the gear 16 to rotate and work. When in use, start the stepping motor 17 to work and drive one of the mixing roller members 15 to rotate. This mixing roller member 15 will drive the corresponding gear 16 to rotate, and this gear 16 will drive another gear 16 to rotate, and the other gear 16 will drive another mixing roller member 15 to rotate. Because the two gears 16 are meshed with each other, their rotation directions during operation are opposite, so the rotation directions of the two mixing roller members 15 are also opposite, thus realizing the mixing work of the phenolic molding compound, providing convenience for the user's work. At this time, the user holds the handle 11 and repeatedly pulls the push rod 3 through the handle 11. The push rod 3 drives the clamping block 9 to move, the clamping block 9 drives the connector 4 to move, and the connector 4 will drive the scraping plate 6 to move closely along the surface of the two mixing roller members 15. And when the mixing roller member 15 is rotating, the residues on the surface of the mixing roller member 15 are scraped clean. In this way, the user only needs to pull the push rod 3 a few times to quickly scrape off the residues, improving the efficiency of the user's scraping work and providing convenience for the user's work.
[0030] Therefore, a structural design of scraping residues is adopted on the mixer. When the mixing roller is rotating, the push rod 3 is repeatedly pulled to drive the scraper 6 to move closely along the mixing roller. Under the action of the scraper 6, the residues on the mixing roller can be quickly scraped off, saving a lot of time, improving the efficiency of the user in cleaning the mixing roller, and providing convenience for the user's work.
[0031] One side of the surface of the push rod 3 is sleeved with a clamping block 9. The clamping block 9 is clamped inside the fixed column 2, and a through hole 10 adapted to the push rod 3 is opened on one side of the clamping block 9.
[0032] Specifically, due to the setting of the clamping block 9 and the through hole 10, the clamping block 9 is clamped inside the fixed column 2, so that the push rod 3 can be limited, ensuring that the push rod 3 can always move and work at a horizontal angle. During work, the push rod 3 slides in the through hole 10. At the same time, it is also convenient for the user to remove and maintain or replace the push rod 3 and the scraper 6, providing convenience for the user's work.
[0033] One end of the push rod 3 away from the clamping block 9 is fixedly installed with a handle 11, and anti-slip lines are arranged on the surface of the handle 11.
[0034] Specifically, due to the setting of the handle 11 and the anti-slip lines on the handle 11, it can prevent the user from slipping when pushing or pulling the push rod 3, providing assistance for the user's work.
[0035] The positioning component includes a movable cavity 12 opened at the top of the connecting head 4. A fixing pin 13 is movably installed inside the movable cavity 12. The bottom end of the fixing pin 13 penetrates into the inside of the scraper 6. A spring 14 is sleeved on the surface of the fixing pin 13. The bottom end of the spring 14 is fixedly connected to the inner wall of the movable cavity 12, and the top end of the spring 14 is fixedly connected to the fixing pin 13.
[0036] Specifically, due to the setting of the positioning component, after the scraper 6 is clamped into the connecting head 4, the end of the fixing pin 13 will also be clamped into the inside of the scraper 6 to fix the scraper 6 on the connecting head 4. The process is as follows: when the scraper 6 is clamped into the installation cavity 7, it will first push the fixing pin 13 upward, and at the same time, the fixing pin 13 will also stretch the spring 14. Then, after the jacking hole on the scraper 6 is aligned with the fixing pin 13, under the action of the spring 14, the fixing pin 13 is pulled back and the end of the fixing pin 13 is inserted into the jacking hole on the scraper 6, that is, inserted into the scraper 6. Finally, the scraper 6 is fixed on the connecting head 4, ensuring the stability of the scraper 6 during work. Moreover, it is also convenient for the user to remove and replace the scraper 6. When replacing, just pull out the scraper 6 with force, providing convenience for the user's maintenance work.
[0037] A plurality of mixing roller members 15 are rotatably installed inside the frame 1. The plurality of mixing roller members 15 are all adapted to the scraper 6 and the arc-shaped groove 8. A plurality of meshing gears 16 sleeved on the mixing roller members 15 are embedded on one side of the frame 1. One side of the top of the frame 1 is fixedly installed with a stepping motor 17, and the output shaft of the stepping motor 17 is fixedly connected to one of the mixing roller members 15.
[0038] Specifically, with the settings of the mixing roller members 15, the gears 16 and the stepping motor 17, the stepping motor 17 is used to drive the mixing roller members 15 and the gears 16 to rotate and work. When in use, start the stepping motor 17 to work and drive one of the mixing roller members 15 to rotate. This mixing roller member 15 will drive the corresponding gear 16 to rotate. This gear 16 will drive another gear 16 to rotate, and the other gear 16 will drive another mixing roller member 15 to rotate. Because the two gears 16 are meshed with each other, their rotation directions during operation are opposite. Therefore, the rotation directions of the two mixing roller members 15 are also opposite, thus realizing the mixing work of the phenolic molding compound and providing convenience for the user's work.
[0039] A collection box 18 is arranged at the bottom inside the frame 1. Both sides of the collection box 18 are fixedly installed with a first convex tooth plate 19, and both ends inside the frame 1 are embedded with a second convex tooth plate 20 adapted to the first convex tooth plate 19.
[0040] Specifically, with the settings of the collection box 18, the first convex tooth plate 19 and the second convex tooth plate 20, the collection box 18 is used to collect the fallen residues, realizing recycling, saving resources and reducing cost investment. The first convex tooth plate 19 and the second convex tooth plate 20 can be meshed with each other. And based on the material characteristics of the first convex tooth plate 19 and the second convex tooth plate 20, an elastic material such as plastic is used. When the first convex tooth plate 19 is stationary, the second convex tooth plate 20 can still move along with the collection box 18. At the same time, the cooperation of the first convex tooth plate 19 and the second convex tooth plate 20 can also limit and fix the installation of the collection box 18, providing convenience for the user's work.
