Description

Technical Field

[0001] The utility model relates to the technical field of polymer material processing, and specifically relates to a reaction device for polymer materials. Background Technique

[0002] Polymer materials, also known as polymer materials, are materials composed of a polymer compound as the matrix and other additives (auxiliary materials). In the preparation process of polymer materials, a reaction device is required to melt and mix several resin particles to produce polymer materials with special properties.

[0003] Currently, in the preparation process of polymer materials, the proportioned auxiliary materials are usually directly added into the reaction device to mix with the polymer materials. Although this makes the feeding speed of the polymer materials and the auxiliary materials relatively fast, the direct addition of the auxiliary materials makes it difficult for the auxiliary materials to diffuse, and the mixing time between the auxiliary materials and the polymer materials is relatively long. This will result in a low mixing reaction efficiency between the auxiliary materials and the polymer materials, and a low preparation effect of the polymer material products.

[0004] Therefore, we propose a reaction device for polymer materials to solve the above problems. Content of the Utility Model

Embodiment

[0025] As Figures 1-5 shown, a polymer material reaction device proposed in an embodiment of the present invention includes a reaction tank 1 and a tank cover 2 provided on the reaction tank 1. A second feed hopper 25 is fixedly provided on the upper end surface of the tank cover 2. A secondary material equal feeding assembly and a mixing assembly are sequentially provided on the upper end surface of the tank cover 2. The secondary material equal feeding assembly is used to intermittently and equally feed the secondary materials used in the polymer material reaction into the inner side of the reaction tank 1. A connection and pushing assembly is provided between the secondary material equal feeding assembly and the mixing assembly. The connection and pushing assembly is used to drive the mixing assembly to move back and forth in the vertical direction with the kinetic energy generated when the secondary material equal feeding assembly works. The mixing assembly is used to stir the reaction materials inside the reaction tank 1, and while stirring the reaction materials, it also cleans the reaction materials attached to the inner wall surface of the reaction tank 1. When the mixing assembly moves back and forth in the vertical direction, it will clean the reaction materials at different heights on the inner wall surface of the reaction tank 1.

[0026] The secondary material equal feeding assembly includes a protection cylinder 9 fixedly provided on the tank cover 2. The protection cylinder 9 is communicated with the reaction tank 1. A first feed hopper 10 is fixedly provided on the upper end surface of the protection cylinder 9. A secondary material equal feeding cylinder 11 is rotatably provided inside the protection cylinder 9. A plurality of material storage ports 12 are sequentially opened on the secondary material equal feeding cylinder 11. One end of the protection cylinder 9 is fixedly provided with a first servo motor 13, and the output end of the first servo motor 13 is docked with the secondary material equal feeding cylinder 11.

[0027] Through the setting of the secondary material equal feeding assembly, the secondary materials filled in the material storage ports 12 on the secondary material equal feeding cylinder 11 are equally fed into the reaction tank 1 intermittently, which can shorten the mixing time between the secondary materials added into the reaction tank 1 and the polymer materials, thereby effectively improving the preparation efficiency of the polymer material finished products.

[0028] The mixing assembly includes a plurality of guide rods 300 fixedly arranged on the tank cover 2. The plurality of guide rods 300 are located on one side of the protective cylinder 9. Limit blocks are fixedly arranged at the tops of the guide rods 300. A support plate 3 is sleeved on the guide rods 300. A second servo motor 4 is fixedly arranged on the support plate 3. The output end of the second servo motor 4 is provided with a drive shaft 5. A plurality of stirring and mixing rods 6 are fixedly arranged on the drive shaft 5 in sequence. A connecting ring 19 is sleeved on the drive shaft 5. Two first connecting plates 7 are rotatably arranged on the connecting ring 19 in sequence. Scrapers 8 are rotatably arranged at the ends of the first connecting plates 7 away from the connecting ring 19. Two second connecting plates 70 are rotatably arranged on the drive shaft 5 in sequence. An activity groove is opened at the connection between the drive shaft 5 and the second connecting plate 70. The second connecting plate 70 is rotatably arranged in the activity groove and also slidably arranged in the activity groove. The two second connecting plates 70 correspond to the positions of the two first connecting plates 7 respectively. The ends of the two second connecting plates 70 away from the drive shaft 5 are respectively rotatably connected to the two scrapers 8.

[0029] The setting of the mixing assembly enables the polymer materials in the reaction tank 1 to scrape off the reaction materials adhering to the inner wall surface of the reaction tank 1 while being stirred. This can not only reduce the reaction ratio between the polymer materials and the auxiliary materials, but also effectively improve the production quality of the polymer materials.

[0030] A first slider 20 is fixedly arranged inside the connecting ring 19. A first chute 21 is opened on the drive shaft 5. The first slider 20 on the connecting ring 19 is slidably arranged in the first chute 21 on the drive shaft 5. Two connecting cylinders 22 are fixedly arranged on the drive shaft 5 in sequence. A plug rod 23 is inserted into the connecting cylinder 22. A spiral spring 24 is arranged in the connecting cylinder 22. The two ends of the spiral spring 24 are respectively fixedly connected to the inner bottom end of the connecting cylinder 22 and the plug rod 23 inserted into the connecting cylinder 22. The end of the plug rod 23 away from the connecting cylinder 22 is fixedly connected to the scraper 8.

[0031] Through the setting of the first slider 20 and the first chute 21, not only can the connecting ring 19 move up and down, so that the horizontal extension length of the scraper 8 can be adjusted, thereby enabling the mixing assembly to be applicable to reaction tanks 1 with different diameters, but also the up and down movement of the connecting ring 19 is limited in position.

[0032] The connecting and pushing component includes a disc 14 rotatably arranged at one end of the protection cylinder 9. A first pushing plate 140 is rotatably arranged on the disc 14. A second slider 17 is fixedly arranged at the end of the first pushing plate 140 away from the disc 14. Fixing plates 15 are arranged on both sides of the first pushing plate 140. Second chutes 16 are formed in the fixing plates 15. The second slider 17 on the first pushing plate 140 is slidably arranged in the second chutes 16 on the fixing plates 15. A second pushing plate 18 is rotatably arranged at the end of the first pushing plate 140 away from the disc 14. The end of the second pushing plate 18 away from the first pushing plate 140 is rotatably connected to the support plate 3.

[0033] Through the arrangement of the connecting and pushing component, the kinetic energy generated when the auxiliary material equal - amount feeding component works can drive the mixing component to move back and forth in the vertical direction. The movement of the mixing component can stir the polymer materials at different depths inside the reaction tank 1 and scrape off the reaction materials attached to different heights of the inner wall surface of the reaction tank 1. In this way, not only can the stirring effect of the polymer materials be improved, but also the mixing ratio between the polymer materials and the auxiliary materials can be reduced.

[0034] The working principle of this utility model:

[0035] First, add the polymer materials into the reaction tank 1 through the second feed hopper 25. Then start the second servo - motor 4. The start of the second servo - motor 4 drives the drive shaft 5 to rotate. The rotation of the drive shaft 5 drives the stirring and mixing rod 6 and the scraper 8 to rotate. The stirring and mixing rod 6 stirs the polymer materials in the reaction tank 1, and the stirring of the scraper 8 scrapes off the reaction materials attached to the inner wall surface of the reaction tank 1. When it is necessary to add auxiliary materials to the polymer materials in the reaction tank 1, add the auxiliary materials into the first feed hopper 10. The auxiliary materials in the first feed hopper 10 will fall into the storage port 12 on the auxiliary - material equal - amount feeding cylinder 11 below the first feed hopper 10. Then start the first servo - motor 13. The start of the first servo - motor 13 drives the auxiliary - material equal - amount feeding cylinder 11 to rotate. During the rotation of the auxiliary - material equal - amount feeding cylinder 11, the storage port 12 storing the auxiliary materials feeds the reaction tank 1, and the empty storage port 12 will rotate to the lower part of the first feed hopper 10 for feeding. This process is repeated. During the rotation of the auxiliary - material equal - amount feeding cylinder 11, it will drive the disc 14 to rotate. The rotation of the disc 14 drives one end of the first pushing plate 140 to do circular motion, and the other end of the first pushing plate 140 moves horizontally back and forth along the second chute 16. The movement of the first pushing plate 140 drives one end of the second pushing plate 18 to move. The movement of the second pushing plate 18 drives the support plate 3 to move in the vertical direction along the guide rod 300. The movement of the support plate 3 drives the stirring and mixing rod 6 and the scraper 8 to move. The movement of the stirring and mixing rod 6 will stir the polymer materials at different depths inside the reaction tank 1, and the movement of the scraper 8 will scrape off the reaction materials attached to the inner wall surface of the reaction tank 1.
