Description
Technical Field
[0001] This application relates to the field of modifier particles, and in particular to a device for precise metering and adding modifier particles. Background Technology
[0002] Modifier particles refer to tiny particulate substances with specific functions added during material processing. They are mainly used to change the physical, chemical, or processing properties of base materials (such as plastics, rubber, and mineral powders). Their core function is to interact with the matrix material through physical coating, chemical bonding, or mechanical mixing to achieve targeted optimization of material properties. Modifier particles are often added with precise metering using a precision weighing and feeding machine. Precision metering and feeding equipment for modifier particles is an industrial equipment specifically designed to control the proportion and uniformity of modifiers added during material processing. It ensures stable modification effects through intelligent metering, dynamic proportioning, and dispersion technology. When using a conventional precision weighing and feeding machine, after connecting the power supply, the top of the weighing and feeding machine is equipped with a hopper into which the modifier particles are placed. The surface of the weighing and feeding machine is equipped with a placement rack for easy placement of containers. The weighing and feeding machine controls the weighing of the modifier particles in the hopper and adds them to the container.
[0003] Regarding the aforementioned technologies, the inventors believe that when using conventional precision weighing and feeding machines, due to the fixed particle size of the modifier, the addition of the modifier is prone to deviations due to the large particle weight, which affects the accuracy of the addition of the modifier particles.

[0022] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.
[0023] This application discloses a device for precise metering and adding modifier particles, referring to... Figure 1 - Figure 2 The system includes a weighing and feeding machine 1. When in use, after connecting the weighing and feeding machine 1 to the power supply, a feeding hopper 2 is installed on the top of the weighing and feeding machine 1. Modifier granules are placed into the feeding hopper 2. A placement rack 3 is installed on the surface of the weighing and feeding machine 1, facilitating the placement of containers. The weighing and feeding machine 1 controls the weighing of the modifier granules in the feeding hopper 2 and adds them to the container. A connecting cylinder 4 is installed inside the feeding hopper 2, and an installation plate 5 is connected to the top of the connecting cylinder 4. A pressure plate 6 is rotatably connected to the inner wall of the installation plate 5. Several grinding grooves 7 are opened on the surfaces of both the installation plate 5 and the pressure plate 6. Modifier is placed between the pressure plate 6 and the installation plate 5, and the modifier granules are ground into powder through the grinding grooves 7 and added to the feeding hopper 2. This effectively improves the accuracy of the modifier granule addition and prevents the situation where the fixed size of the modifier granules makes accurate addition difficult.
[0024] Reference Figure 2 A motor 8 is installed on the top of the mounting plate 5. A rotating gear 9 is installed at the output end of the motor 8. The surface of the rotating gear 9 meshes with the connecting groove 10 on the surface of the pressure plate 6. After the motor 8 is started, the rotating gear 9 is controlled to rotate, thereby controlling the pressure plate 6 to rotate, effectively reducing the amount of manual operation. A shielding plate 11 is connected to the top of the mounting plate 5. The top of the shielding plate 11 has a feed port 12, and a fixing bolt 13 is snapped into the inside of the shielding plate 11. The surface of the fixing bolt 13 is threaded to the inside of the mounting plate 5. The shielding plate 11 shields the top of the mounting plate 5, and the fixing bolt 13 can be separated from the mounting plate 5 to facilitate the disassembly of the shielding plate 11. A spiral feeding plate 14 is installed at the bottom of the pressure plate 6. The surface of the feeding plate 14 is rotatably connected to the inner wall of the connecting cylinder 4. The rotation of the pressure plate 6 drives the feeding plate 14 to rotate inside the connecting cylinder 4, thereby adding the modified agent powder ground by the pressure plate 6 into the feed hopper 2.
[0025] Reference Figure 3 - Figure 4The connecting frame 15 is installed on the surface of the connecting cylinder 4. The surface of the connecting frame 15 is slidably connected to the limiting frame 16. The inner wall of the limiting frame 16 is engaged with the surface of the feed hopper 2. The connecting frame 15 and the limiting frame 16 are used to install the connecting cylinder 4 on the surface of the feed hopper 2 and to separate the limiting frame 16 from the surface of the feed hopper 2, which facilitates the installation and disassembly of the device. The limiting frame 16 is rotatably connected to a threaded rod 17. The surface of the threaded rod 17 is threadedly installed on the inner wall of the connecting frame 15. The rotation of the threaded rod 17 controls the sliding of the connecting frame 15 inside the limiting frame 16, thereby adjusting and fixing the position of the limiting frame 16. The surface of the limiting frame 16 is equipped with a rubber auxiliary piece 18. The surface of the auxiliary piece 18 is movably connected to the surface of the feed hopper 2. The auxiliary piece 18 increases the friction between the limiting frame 16 and the surface of the feed hopper 2, thereby improving the stability of the limiting frame 16 after installation.
[0026] The implementation principle of the precise metering and adding device for modifier particles in this application embodiment is as follows: A connecting cylinder 4 is installed inside the feed hopper 2. The top of the connecting cylinder 4 is connected to an installation plate 5. A pressure plate 6 is rotatably connected to the inner wall of the installation plate 5. Several grinding grooves 7 are provided on the surfaces of both the installation plate 5 and the pressure plate 6 to facilitate the placement of the modifier between the pressure plate 6 and the installation plate 5. The modifier particles are ground into powder through the grinding grooves 7 and added to the feed hopper 2, preventing the fixed size of the modifier particles from hindering precise addition. A motor 8 is installed on the top of the installation plate 5. A rotating gear 9 is installed at the output end of the motor 8. The surface of the rotating gear 9 meshes with the connecting groove 10 on the surface of the pressure plate 6, allowing the rotating gear to be controlled after the motor 8 is started. The rotation of wheel 9 controls the rotation of pressure plate 6, effectively reducing manual operation. A shielding plate 11 is connected to the top of mounting plate 5. The top of shielding plate 11 has a feed inlet 12, and a fixing bolt 13 is snapped into the inside of shielding plate 11. The surface of fixing bolt 13 is threaded to the inside of mounting plate 5, so that the top of mounting plate 5 can be shielded by shielding plate 11. After the fixing bolt 13 is separated from mounting plate 5, shielding plate 11 can be easily disassembled. A spiral feeding plate 14 is installed at the bottom of pressure plate 6. The surface of feeding plate 14 is rotatably connected to the inner wall of connecting cylinder 4, so that the rotation of pressure plate 6 drives feeding plate 14 to rotate inside connecting cylinder 4, thereby adding the modified agent powder ground by pressure plate 6 into feeding hopper 2.
[0027] Alternatively, the connecting frame 15 can be installed on the surface of the connecting cylinder 4. The surface of the connecting frame 15 is slidably connected to the limiting frame 16. The inner wall of the limiting frame 16 is engaged with the surface of the feed hopper 2, so that the connecting cylinder 4 can be installed on the surface of the feed hopper 2 by means of the connecting frame 15 and the limiting frame 16, and the limiting frame 16 can be separated from the surface of the feed hopper 2, which facilitates the installation and disassembly of the device. The inside of the limiting frame 16 is rotatably connected to a threaded rod 17. The surface of the threaded rod 17 is threadedly installed on the inner wall of the connecting frame 15, so that the connecting frame 15 can be controlled to slide inside the limiting frame 16 by rotating the threaded rod 17, thereby adjusting and fixing the position of the limiting frame 16. The surface of the limiting frame 16 is equipped with a rubber auxiliary piece 18. The surface of the auxiliary piece 18 is movably connected to the surface of the feed hopper 2, so that the friction between the limiting frame 16 and the surface of the feed hopper 2 can be increased by means of the auxiliary piece 18, thereby improving the stability of the limiting frame 16 after installation.
