[0002] Modified plastic additives, also known as plastic auxiliaries, refer to various auxiliary materials added before or during plastic molding to improve the production and performance of finished products, such as plasticizers, foaming agents, and flame retardants.
[0003] Currently, in the production process of plastic products, it is necessary to use an additive device to add various modified plastic additives to the production equipment. However, the addition of additives in the production of modified plastics generally has the following problems: when adding multiple additives at the same time, they generally need to be added sequentially or in different additive devices, which makes it impossible to add multiple additives quantitatively at the same time. This results in a long addition time and complicated operation. In addition, multiple additives will be dispersed in different positions and mixed unevenly with the plastic matrix, causing fluctuations in the quality of the finished product. Therefore, it is urgent to design a modified plastic additive addition device to solve the above problems. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] Please see Figures 1-6In this embodiment of the present invention, a modified plastic additive adding device includes a feeding hopper 3. Multiple support legs 2 are installed at the bottom of the feeding hopper 3 for mounting the feeding hopper 3 onto the production equipment body 1. A storage tank 4 is installed at the top of the feeding hopper 3. Mounting holes 18 are provided at the middle of the top and bottom of the storage tank 4. The inner walls of the two mounting holes 18 are respectively rotatably connected to a mounting shaft 17 and a mounting tube 21 via bearings. A rotating cylinder 11 is installed at the bottom of the mounting shaft 17 and the top of the mounting tube 21. A rotating mechanism 7 is provided at the top of the storage tank 4 to drive the mounting shaft 17 and the rotating cylinder 11 to rotate. The rotating mechanism 7 includes a first gear 701 mounted on the top of the mounting shaft 17, and a rack frame 702 meshes with one side of the first gear 701. A fixing frame 704 is fixedly installed at the top of the storage tank 4. The inner wall of the fixed frame 704 is rotatably connected to a threaded rod 703, and one end of the rack frame 702 is provided with a threaded hole that matches the outer wall of the threaded rod 703. One end of the fixed frame 704 is equipped with a forward and reverse motor 706 for driving the threaded rod 703 to rotate, and a guide groove 705 is provided on one side of the fixed frame 704. A guide block 707 that slides in the guide groove 705 is fixed on the rack frame 702. The forward and reverse motor 706 drives the threaded rod 703 to rotate, which drives the rack frame 702 to make linear motion. The meshing action of the rack frame 702 and the first gear 701 drives the mounting shaft 17 and the rotating drum 11 to rotate, so that the rotating drum 11 rotates at a fixed angle each time. When the rotating drum 11 rotates, the storage chamber is aligned with the discharge port 19 in sequence, and the auxiliary agent falls into the feed hopper 3 through the discharge port 19, forming a quantitative feeding function.
[0028] The bottom of the inner wall of the feed hopper 3 is equipped with reinforcing rods 16 that are evenly distributed, and the top of the reinforcing rods 16 is fixed with a support column 15. The top of the support column 15 and the inside of the rotating drum 11 are equipped with a heating component. The top of the support column 15 and the bottom of the mounting tube 21 are also equipped with an agitator 14. The agitator 14 includes a rotating cover 1401 installed at the bottom of the mounting tube 21. A gear ring 1405 is installed on the inner wall of the rotating cover 1401 near the bottom. The top surface of the support column 15 is equipped with a mounting plate 1404, and the mounting plate 1404 has first connecting holes that are evenly distributed. The inner wall of each of the first connecting holes is rotatably connected to an agitator shaft 1402 through a bearing. Each agitator shaft 1402 has an inclined agitator blade 1403 installed at equal intervals at its bottom. A second gear 1406 is installed on the top of the outer wall of each agitator shaft 1402, and the second gear 1406 meshes with the inner wall of the gear ring 1405. The rotating drum 11 synchronously drives the rotating cover 1401 and the gear ring 1405 to rotate. The meshing action of the gear ring 1405 and the second gear 1406 drives the multiple agitator shafts 1402 and agitator blades 1403 to rotate. The agitator blades 1403 generate radial stirring and axial pushing action on the auxiliary agent falling from the discharge port 19, ensuring that the material is fully mixed before entering the production equipment body 1 and avoiding stratification.
[0029] Specifically, the outer wall of the rotating drum 11 is equipped with pusher seats 12 that are evenly distributed, and the surface of the pusher seats 12 is fixed with a sealing gasket 13 that fits against the inner wall of the storage tank 4. The sealing gasket 13, the pusher seats 12 and the rotating drum 11 divide the interior of the storage tank 4 into multiple storage cavities of the same volume. The top of each storage cavity is fixed with a filling pipe 5, and the top of each filling pipe 5 is screwed with a sealing cap 6. The bottom of the storage tank 4 is provided with discharge ports 19 that are evenly distributed, and the discharge ports 19 are located below the sealing gasket 13. The number of discharge ports 19, the number of storage cavities and the number of stirring shafts 1402 are equal, and the stirring shafts 1402 are located below the discharge ports 19. The various auxiliary agents can be classified and stored through each storage cavity to avoid mixing and contamination.
[0030] Specifically, a viewing port 20 is provided on one side of the storage chamber, and a viewing plate 8 is installed on the inner wall of the viewing port 20. The material level can be observed through the viewing plate 8, which facilitates timely material addition.
[0031] Specifically, a base plate 25 is fixed to the outer wall of the support column 15 near the top, and the base plate 25 has second connecting holes at equal intervals for the stirring shaft 1402 to pass through. The inner wall of the second connecting hole is rotatably connected to the outer wall of the stirring shaft 1402 through a bearing. A sealing strip 26 is installed on the outer circumference of the base plate 25 and fits against the bottom of the inner wall of the rotating cover 1401. The base plate 25 and the sealing strip 26 are used to seal the rotating cover 1401 to prevent the auxiliary agent from flying out during stirring and entering the gear structure and affecting the transmission.
[0032] Specifically, the heating assembly includes a connecting groove 22 formed on the support column 15, and the bottom inner wall of the connecting groove 22 is designed to be inclined. A heater 24 is installed on the inner wall of the connecting groove 22, and a heating tube 23 inserted into the rotating drum 11 is installed on the top of the heater 24. Detection ports are provided on the visible panel 8, and temperature sensors 9 are installed on the inner wall of each detection port. A controller 10 is installed on one side of one of the support legs 2. The controller 10 is electrically connected to the forward and reverse motor 706, the temperature sensor 9 and the heater 24. The temperature is monitored by the temperature sensor 9, and the inside of the rotating drum 11 is heated by the heater 24 and the heating tube 23, which can heat the auxiliary agent and maintain the physical stability of the auxiliary agent.
[0033] The working principle of this utility model is as follows: the material pusher seat 12 and sealing gasket 13 on the outer wall of the rotating drum 11 divide the inside of the storage barrel 4 into multiple storage chambers of equal volume. Each storage chamber is independently fed through the top injection pipe 5 and sealed with the sealing cover 6, thereby storing a variety of auxiliary agents. The material level and temperature are observed through the visual panel 8 and temperature sensor 9. The inside of the rotating drum 11 is heated through the heater 24 and heating pipe 23, which can heat the auxiliary agents and maintain the physical stability of the auxiliary agents.
[0034] When feeding, start the forward and reverse motor 706 to drive the threaded rod 703 to rotate, which in turn drives the rack frame 702 to move linearly along the guide groove 705. Since the rack frame 702 meshes with the first gear 701, it can drive the mounting shaft 17 and the rotating drum 11 to rotate, and make the rotating drum 11 rotate a fixed angle each time. When the rotating drum 11 rotates, the storage chamber is aligned with the discharge port 19 in sequence, and the auxiliary agent falls into the feed hopper 3 through the discharge port 19, forming a quantitative feeding function.
[0035] When the rotating drum 11 rotates, it synchronously drives the mounting tube 21 and the rotating cover 1401 to rotate. The gear ring 1405 on the inner wall of the rotating cover 1401 meshes with the second gear 1406 at the top of the stirring shaft 1402, causing multiple stirring shafts 1402 to rotate, thereby driving the stirring blades 1403 to rotate. The stirring blades 1403 generate radial stirring and axial pushing action on the auxiliary agent falling from the discharge port 19, ensuring that the material is fully mixed before entering the production equipment body 1, avoiding stratification. The mixed material falls into the production equipment body 1 through the feed hopper 3.
[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
