[0002] Plastic particles, a common name for plastic granules, are the raw materials used to store, transport, and process plastics in semi-finished form. Polypropylene is a commonly used general-purpose plastic. When uncolored, it appears translucent and waxy. Compared to polyethylene, it is lightweight, transparent, and has a higher hardness. It is primarily used in a variety of products, including basins, buckets, furniture, films, woven bags, strapping tape, bottle caps, and car bumpers. Existing modified polypropylene plastic particles are typically made by mixing polypropylene with one or more additives, such as plasticizers, stabilizers, lubricants, and colorants. However, the uniformity of the mixing of these materials significantly affects the physical properties of the resulting modified polypropylene plastic particles.

[0025] The polypropylene plastic modified particle mixing equipment uses one or more sets of stirring rods to fully mix the polypropylene material and various additives. However, the added additives will sink to the bottom. The additives adhere to the bottom of the inner wall, making it impossible to fully mix the material and additives. It will also block the bottom discharge port. The stirring rod cannot stir the bottom of the inner wall of the mixing tank. Therefore, a device is needed to stir and fully mix the additives adhered to the bottom of the inner wall of the mixing tank.

[0026] like Figure 1-3 As shown, the device includes a stirring tank body 1, which is composed of a stirring assembly 2 and a discharge assembly 3. The stirring assembly 2 inside the stirring tank body 1 can fully mix the polypropylene plastic material and the additive, and the discharge assembly 3 can prevent the polypropylene plastic material from clogging the discharge port 301 during stirring.

[0027] First, the specific structure of the stirring assembly 2 is disclosed. The stirring assembly 2 includes a stirring member 201. A stirring rod 202 is installed at the bottom of the stirring member 201. A plurality of leak holes 203 are provided at the bottom of the stirring rod 202. A connecting hole is provided in the middle of the top of the stirring rod 202. The stirring rod 202 is arranged at the bottom of the inner wall of the stirring tank body 1. The plurality of leak holes 203 at the bottom of the stirring rod 202 can better stir and mix the additives adhered to the bottom of the inner wall of the stirring tank body 1. The stirring member 201 includes a motor 2011. A stirring rod 2012 is installed on the output shaft of the motor 2011. The stirring rod 2012 is located inside the stirring tank body 1. The top of the stirring rod 2012 passes through the top of the stirring tank body 1 and is connected to the motor 2011. The bottom of the stirring rod 2012 passes through the connecting hole at the top of the stirring rod 202 and extends to the bottom of the inner wall of the stirring tank body 1. The stirring rod 202 cooperates with the stirring rod 2012 to mix the materials inside the stirring tank body 1.

[0028] By installing a motor 2011 on the outside of the stirring tank body 1, the top of the stirring rod 2012 inside the stirring tank body 1 is connected, so that the motor 2011 can drive the stirring rod 2012 to rotate to stir and mix the materials inside the stirring tank body 1. For the materials adhering to the bottom of the inner wall of the stirring tank body 1, the bottom of the stirring rod 2012 passes through the stirring rod 202 and is rotatably connected to the bottom of the inner wall of the stirring tank body 1, so that the stirring rod 202 is set at the bottom of the inner wall of the stirring tank body 1. The stirring rod 2012 is rotated to drive the stirring rod 202 to rotate. A plurality of leakage holes 203 are provided at the bottom of the stirring rod 202, which can enable the stirring rod 202 to better stir and peel off the materials adhering to the bottom of the inner wall of the stirring tank body 1, so that the materials are fully mixed together, thereby achieving the effect of peeling and mixing the materials adhering to the bottom of the inner wall of the stirring tank body 1, and the stirring rod 202 can also clean the inner wall of the stirring tank body 1 more cleanly.

[0029] The improvement of this embodiment is that: through the stirring rod 202 structure, the stirring rod 202 and the stirring rod 2012 can rotate as a whole, thereby peeling and mixing the adhered materials inside the stirring tank body 1, solving the problem in the prior art that materials or additives adhere to the bottom of the inner wall of the stirring tank body 1, making it impossible to fully mix the materials and additives.

[0030] Since the discharge port 301 in the prior art is columnar, there is a problem that the discharge port 301 is blocked when the material is stirred. Figure 2-Figure 4 A second embodiment of the present invention is shown.

[0031] The specific structure of the discharge assembly 3 is disclosed again. The discharge assembly 3 includes a discharge port 301. The outer surface of the discharge port 301 is provided with a thread. The outer thread of the discharge port 301 is connected to a closing cover 302. A blocking column 303 is fixedly installed on the top of the closing cover 302. The diameter of the blocking column 303 matches the inner diameter of the discharge port 301. The blocking column 303 is inserted into the discharge port 301 through the closing cover 302 so that the top of the blocking column 303 is flush with the bottom of the inner wall of the mixing tank body 1, preventing the mixed material from clogging the discharge port 301. A connecting frame 4 is installed at the bottom of the mixing tank body 1. An electric telescopic rod 5 is installed at the bottom of the connecting frame 4. A support leg 6 is installed at the bottom of the electric telescopic rod 5. The connecting frame 4 is arranged outside the discharge port 301. The connecting frame 4 and the electric telescopic rod 5 can adjust the distance between the mixing tank body 1 and the ground, making it more convenient for the discharge port 301 to discharge the mixed material.

[0032] The blocking column 303 installed inside the closing cover 302 can be inserted into the discharge port 301 through the blocking column 303 on the top of the closing cover 302, and the closing cover 302 is threadedly connected to the outside of the discharge port 301, so that the blocking column 303 extends to the interior of the mixing tank body 1, so that the blocking column 303 is flush with the bottom of the inner wall of the mixing tank body 1, which can prevent the material from entering the discharge port 301 and blocking the discharge port 301 when the material is stirred in the mixing tank body 1, and three electric telescopic rods 5 are installed at the bottom of the connecting frame 4 at the bottom of the mixing tank body 1. The three electric telescopic rods 5 can adjust the distance between the mixing tank body 1 and the ground by telescoping, so that receiving buckets of different sizes can be placed at the bottom of the discharge port 301 of the mixing tank body 1 to receive the mixed materials, thereby preventing the material from blocking the discharge port 301 during stirring and facilitating the receiving of the mixed materials.

[0033] The improvement of this embodiment is that the closure cover 302 and the blocking column 303 structure can prevent the discharge port 301 from being blocked, thereby solving the problems of the discharge port 301 being blocked and the inconvenience in receiving the mixed material in the prior art.

[0034] Considering the problem of how to feed the mixing tank body 1, combined with Figure 1-Figure 4The present practical embodiment is shown, specifically, the mixing tank body 1 includes a feed port 101, and the feed port 101 is provided with multiple feed ports 101. The multiple feed ports 101 are located at the top of the mixing tank body 1 and distributed in a linear array. The multiple feed ports 101 can add materials with different properties to the interior of the mixing tank body 1 for mixing;
