Description
Technical Field
[0001] This utility model relates to the technical field of polypropylene production for automotive trim, and in particular to a feeding device for producing high-compression-resistant polypropylene for automotive trim. Background Technology
[0002] There are many types of automotive decorative products. When producing and processing automotive decorative products with high pressure resistance, polypropylene is often used as the raw material. This is because polypropylene is a semi-crystalline thermoplastic with high impact resistance, strong mechanical properties, and resistance to various organic solvents and acid and alkali corrosion. It has a wide range of applications in industry and is one of the most common polymer materials.
[0003] Polypropylene is mainly produced by the polymerization reaction of propylene monomers under the action of a catalyst. In the production and processing of polypropylene, propylene raw materials are usually added to the reaction tank through a feeding device. Currently available feeding devices have a relatively simple structure, mostly simple hopper structures. When adding propylene raw materials, the raw materials tend to adhere to the inner wall of the hopper and can also easily block the hopper outlet, making the propylene raw material discharge unsmooth and impractical.

The stirring mechanism includes a dual-shaft motor and two sets of cleaning rods. The dual-shaft motor is fixedly installed at the top of the hopper, and a stirring rod is fixedly connected to the bottom output end of the dual-shaft motor. The stirring rod is rotatably mounted on the top of the end cap, and a circular array of [missing information - likely related to cleaning rods]. Multiple sets of material-pulling rods are fixed at equal intervals, with the length of the material-pulling rods gradually decreasing from top to bottom. Two sets of connecting rods of different lengths are fixed on each of the two sets of cleaning rods. The four sets of connecting rods are symmetrically fixed to the outer wall of the stirring rod. Scraping rubber plates are fixed on the outer side of each of the two sets of cleaning rods, and the scraping rubber plates are in contact with the inner wall of the hopper. The striking mechanism includes a fixed frame, which is fixedly connected to the top of the hopper. A drive shaft is rotatably mounted on the fixed frame, and the bottom end of the drive shaft is fixedly connected to the top output end of the dual-axis motor for striking the outer wall of the hopper.

[0008] Preferably, the end cap is symmetrically connected with two sets of hinges, and the end cap is rotated and installed on the feeding port of the hopper tank through the two sets of hinges. Two sets of latches are symmetrically provided on the outer wall of the end cap and the outer wall of the hopper tank to fit together.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: During use, the feeding pipe can be welded to the inlet of the reaction vessel. When adding propylene raw material, open the end cap, pour the propylene raw material into the hopper, then close the end cap and start the dual-shaft motor. Starting the dual-shaft motor causes the stirring rod and drive shaft to rotate. The rotation of the stirring rod drives the material feeding rod to stir the raw material in the hopper, accelerating its flow. The stirring rod, through the connecting rod, drives the cleaning rod to rotate, causing the scraper to scrape the inner wall of the hopper, removing the raw material adhering to it. The rotation of the drive shaft, through the meshing of the driving gear and driven gear, drives the transmission shaft to rotate. The driving gear is larger than the driven gear. The gears cause the drive shaft to rotate at a speed greater than the drive shaft, which in turn drives the transmission rod to rotate via the pulley and transmission belt. This, in turn, causes the transmission rod to rotate the cam. The right end of the T-shaped push rod remains in contact with the outer wall of the cam under the action of the spring. Through the rotation of the cam, the T-shaped push rod slides repeatedly left and right under the action of the cam and the spring. This causes the T-shaped push rod to drive the rubber hammer to continuously strike the outer walls on both sides of the hopper, further shaking off the raw material adhering to the inner wall of the hopper. Through the stirring of the feeding rod and the striking of the rubber hammer, the propylene raw material is quickly added to the reaction vessel through the feeding pipe, thus preventing the propylene raw material from adhering to the inner wall of the hopper, preventing blockage of the hopper outlet, ensuring smooth discharge of propylene raw material, and improving practicality.

A dual-shaft motor 4 is fixedly installed at the top of the hopper tank 1, and a stirring rod 5 is fixedly connected to the bottom output end of the dual-shaft motor 4. The stirring rod 5 is rotatably installed on the top of the end cap 3. Multiple sets of feeding rods 6 are fixedly arranged in a circular array at equal intervals on the stirring rod 5, and the length of the multiple sets of feeding rods 6 gradually decreases from top to bottom. Each of the two sets of cleaning rods 7 is fixed with two sets of connecting rods 8 of different lengths. The four sets of connecting rods 8 are symmetrically fixed to the outer wall of the stirring rod 5. Each of the two sets of cleaning rods 7 is fixed with a scraper 9 on its outer side. The scraper 9 contacts the inner wall of the hopper tank 1. The fixing frame 10 is fixedly connected to the top of the hopper tank 1. A drive shaft 11 is rotatably mounted on the fixing frame 10. The bottom end of the drive shaft 11 is fixedly connected to the top output end of the dual-shaft motor 4. A drive gear 12 is fixedly sleeved on the drive shaft 11. The fixing frame 10 is symmetrically fixed on the left and right sides. Two sets of connecting plates 13 are connected. Two sets of T-shaped support plates 14 are symmetrically fixedly connected to the outer wall of the hopper tank 1. Transmission rods 15 are rotatably mounted on the connecting plates 13 and T-shaped support plates 14 on both sides. Two sets of transmission shafts 16 are symmetrically rotatably mounted on the top of the fixed frame 10. Driven gears 17 are fixedly sleeved on both sets of transmission shafts 16. Both sets of driven gears 17 mesh with the driving gears 12. Pulleys 18 are fixedly sleeved on the top of the two sets of transmission rods 15 and the top of the two sets of transmission shafts 16. The two sets of pulleys 18 on the left side are... Both the upper and right-side pulleys 18 are fitted with transmission belts 19. The bottom ends of both sets of transmission rods 15 are fixedly connected to cams 20. Both sets of T-shaped support plates 14 are slidably provided with T-shaped push rods 21. Both sets of T-shaped push rods 21 are fitted with springs 22. The two ends of the springs 22 are respectively connected to the T-shaped push rods 21 and the T-shaped support plates 14. Both sets of T-shaped push rods 21 are fixedly provided with rubber hammers 23. The right end of the rubber hammers 23 abuts against the inside of the T-shaped support plates 14. The right end of the T-shaped push rods 21 abuts against the outer wall of the cams 20.In use, the feeding port 2 can be welded to the inlet of the reaction vessel. When adding propylene raw material, open the end cap 3 and pour the propylene raw material into the hopper tank 1. Then close the end cap 3 and start the dual-shaft motor 4. By starting the dual-shaft motor 4, the stirring rod 5 and the drive shaft 11 will rotate. The rotation of the stirring rod 5 will drive the feeding rod 6 to stir the raw material in the hopper tank 1, accelerating the flow of the raw material. The stirring rod 5 will also drive the cleaning rod 7 to rotate through the connecting rod 8, causing the scraper 9 to scrape the inner wall of the hopper tank 1, removing the raw material adhering to the inner wall of the hopper tank 1. The rotation of the drive shaft 11 will drive the transmission shaft 16 to rotate through the meshing of the drive gear 12 and the driven gear 17. The drive gear 12 is larger than the driven gear 17, thus causing the transmission shaft 16 to rotate. The speed is greater than that of the drive shaft 11, causing the transmission shaft 16 to drive the transmission rod 15 to rotate through the pulley 18 and the transmission belt 19. This, in turn, causes the transmission rod 15 to drive the cam 20 to rotate. The right end of the T-shaped push rod 21 remains in contact with the outer wall of the cam 20 under the action of the spring 22. Through the rotation of the cam 20, the T-shaped push rod 21 slides repeatedly left and right under the action of the cam 20 and the spring 22. This causes the T-shaped push rod 21 to drive the rubber hammer 23 to continuously strike the outer walls on both sides of the hopper tank 1, further shaking off the raw material adhering to the inner wall of the hopper tank 1. Through the stirring of the feeding rod 6 and the striking of the rubber hammer 23, the propylene raw material is quickly added to the reaction tank through the feeding port 2, thus preventing the propylene raw material from adhering to the inner wall of the hopper, preventing blockage of the hopper outlet, ensuring smooth propylene feeding, and improving practicality.

Two sets of latches 25 are symmetrically provided on the outer wall of the end cap 3 and the outer wall of the hopper tank 1. Through the hinges 24 and latches 25, the latches 25 can make the end cap 3 more tightly and securely closed, and at the same time facilitate the opening of the end cap 3, improving the convenience of use.

[0023] Two sets of stiffening plates 27 are symmetrically fixedly connected between the fixed frame 10 and the top of the hopper tank 1. By setting the stiffening plates 27, the connection between the fixed frame 10 and the hopper tank 1 can be made more firm and stable, and the stability of the drive shaft 11 and the transmission shaft 16 during operation can be improved.
[0024] This utility model discloses a high-pressure resistant polypropylene production feeding device for automotive decoration. Its working principle is as follows: During use, the feeding port 2 can be welded to the inlet of the reaction tank. When adding propylene raw material, the end cap 3 is opened, and the propylene raw material is poured into the hopper tank 1. Then, the end cap 3 is closed, and the dual-shaft motor 4 is started. Starting the dual-shaft motor 4 causes the stirring rod 5 and drive shaft 11 to rotate. The rotation of the stirring rod 5 drives the material-dispensing rod 6 to stir the raw material in the hopper tank 1, accelerating the flow of the raw material. Furthermore, the stirring rod 5, through the connecting rod 8, drives the cleaning rod 7 to rotate, causing the scraper blade 9 to scrape the inner wall of the hopper tank 1, removing the raw material adhering to the inner wall. Through the rotation of the drive shaft 11, the drive shaft 11, via the drive gear 12 and the driven gear 17... The meshing drives the drive shaft 16 to rotate. The size of the driving gear 12 is larger than that of the driven gear 17, which makes the rotation speed of the drive shaft 16 greater than that of the drive shaft 11. The drive shaft 16 drives the transmission rod 15 to rotate through the pulley 18 and the transmission belt 19. The transmission rod 15 then drives the cam 20 to rotate. The right end of the T-shaped push rod 21 is kept in contact with the outer wall of the cam 20 under the action of the spring 22. Through the rotation of the cam 20, the T-shaped push rod 21 slides left and right repeatedly under the action of the cam 20 and the spring 22. Thus, the T-shaped push rod 21 drives the rubber hammer 23 to continuously strike the outer walls on both sides of the hopper tank 1, further shaking off the raw materials attached to the inner wall of the hopper tank 1. Through the stirring of the feeding rod 6 and the striking of the rubber hammer 23, the propylene raw material is quickly added to the reaction tank through the feeding port 2.
