Description

Technical Field

[0001] The utility model belongs to the technical field of plastic processing and production, and particularly relates to a plastic particle mixing and receiving device. Background Art

[0002] In the plastic processing industry, plastic particle mixing is an important link in the production process. During the transportation of plastic particles, due to reasons such as electrostatic adsorption, irregular particle shapes, or humidity differences, particles often adhere to each other and block the discharge port, forming a "material bridge" phenomenon, resulting in poor material flow, affecting the mixing effect and the smooth progress of subsequent processing. For a hopper at a relatively high position, the traditional method of breaking the bridge often requires manual use of tools such as long sticks to knock on the hopper wall to break the adhesion between particles and restore the material flow. This manual method of breaking the bridge not only has a high labor intensity and low efficiency, but also increases the operation difficulty and safety hazards, and affects the continuity and stability of the production line.

[0015] The technical solutions of the present utility model will be further described in detail below in conjunction with the specific embodiments.

[0016] Such as Figure 1As shown, the utility model provides a plastic particle mixing and collecting device, which includes a barrel 1 filled with cut plastic particles, a collecting barrel 2 is arranged above the barrel 1, and a feeding pipe 3 is arranged between the barrel 1 and the collecting barrel 2, and the feeding pipe 3 is used to transport the plastic particles in the barrel 1 to the collecting barrel 2. Among them, the top of the collecting barrel 2 is provided with a feed port 4 and an air extraction port 5, one end of the feed pipe 3 is connected to the inside of the barrel 1, and the other end of the feed pipe 3 is connected to the feed port 4, and the air extraction port 5 is connected to an air extraction device 6, and the air extraction device 6 includes an air extraction pipe 7 and an air extraction pump 8 connected to the air extraction pipe 7. A discharge port 9 is arranged at the bottom of the collecting barrel, and a cover plate 10 capable of closing the discharge port 9 is arranged at the discharge port 9. The cover plate 10 of the utility model can be an iron plate, etc., based on the ability to achieve the above functions, and the cover plate 10 is movably connected to the collecting barrel 2, such as a pivot connection. When in use, the vacuum pump 8 is turned on, and the vacuum pipe 7 starts to evacuate the collection barrel 2. The cover plate 10 will be adsorbed to the discharge port 9 due to the negative pressure in the collection barrel 2, and the discharge port 9 will be covered and closed. Then, the feeding pipe 3 connected to the collection barrel 2 will suck the plastic particles in the barrel 1 into the collection barrel 2 due to the negative pressure, so as to transport the plastic particles. A mixing device 11 is provided at the bottom of the discharge port 9. When there are more plastic particles in the collection barrel 2, the plastic particles will press open the cover plate 10 covering the discharge port 9 due to their weight, thereby opening the discharge port 9 and flowing into the mixing device 11 from the discharge port 9. A collecting device 12 is provided below the mixing device 11. After the plastic particles are mixed by the mixing device 11, they are collected by the collecting device 12.

[0017] Furthermore, the bottom of the collecting barrel 2 is conical. A blowing port 13 is provided on one side of the bottom of the collecting barrel 2 for blowing air near the discharge port 9, and the blowing port 13 is connected to a blowing duct 14 and a fan 15. When in use, the fan 15 is turned on to blow air to the discharge port 9, which can effectively prevent the plastic particles from sticking at the discharge port 9. Compared with the traditional method of manually knocking the barrel wall to break the bridge, the utility model is more convenient and safer.

[0018] Furthermore, the volume of the mixing device 11 of the utility model is larger than the volume of the collecting barrel 2. A stirring blade 16 for stirring plastic particles is provided inside the mixing device 11, and the stirring blade 16 is connected to a driving motor (not shown). A valve 19 is provided at the bottom outlet 18 of the mixing device 11. The collecting device 12 includes a collecting barrel 20 and a weighing platform 21 provided below the collecting barrel 20. The mixed plastic particles flow out through the bottom outlet 18 of the mixing device 11, enter the collecting barrel 20, and are weighed by the weighing platform 21 to achieve accurate collecting.

[0019] The utility model has a compact structure and saves floor space. By using the air extraction device 6 to form a negative pressure in the collection barrel 2, plastic particles can be effectively transported. The bottom of the collection barrel 2 is designed in a conical shape and is equipped with a blowing device, which effectively prevents the plastic particles from sticking at the discharge port 9, improves the fluidity of the material and the smoothness of discharging, and further improves the production efficiency.
