Description

Technical Field

[0002] Plastics are mainly composed of carbon, oxygen, hydrogen, nitrogen and other organic or inorganic elements. The finished product is solid and widely used in home appliances, automobiles, mobile phones, PCs, medical equipment, lighting appliances. In the production of plastic particles, a mixing device is used. For example, the patent with publication number CN218256086U discloses a mixing device for plastic particle granulation, including: a bottom plate, a fixing frame, a tank body, a cover plate, a feed port, a discharge pipe, a stirring mechanism and a feeding mechanism. When this device is used, the plastic particle raw material is added into the tank body through the feed port, and the first motor is started to rotate the stirring rod. The plastic particle raw material in the tank body is stirred by the rotating stirring rod. After stirring and mixing, the plastic particle raw materials are evenly mixed, and the valve is opened. The evenly mixed plastic particle raw materials enter the interior of the barrel through the discharge pipe. When the barrel is full, the second motor is started to rotate the rotating plate, and the barrel is driven to rotate 90° through the rotating plate. The evenly mixed plastic particle raw materials are discharged through the next barrel. The above operation is repeated to discharge the evenly mixed plastic particle raw materials, thereby realizing the automation of feeding, shortening the feeding time, and improving the feeding efficiency. However, there is a certain gap between the two barrels of the device. During the rotation process, some particles are easy to fall into the gap, resulting in waste of plastic particles.

DETAILED DESCRIPTION

[0020] In this embodiment, a first motor 2 is fixed to the lower side of the support frame, the output end of the first motor 2 is fixedly connected to the rotating plate 1, a material guide groove 16 is opened on the material guide plate 6, the middle part of the material guide groove 16 is higher than the two ends of the material guide groove 16, and the two ends of the material guide groove 16 are respectively located above the material receiving barrel 5.

[0021] Specifically, when collecting materials, the material is discharged from the discharge port 11, and the evenly mixed plastic particles fall from the discharge port 11, and the plastic particles enter the receiving barrel 5. When one of the receiving barrels 5 is full, the first motor 2 is started, so that the first motor 2 drives the rotating plate 1 to rotate, thereby driving the receiving barrel 5 to rotate. At this time, the fallen plastic particles fall into the material guide groove 16, and then enter the receiving barrel 5 through the material guide groove 16 until the receiving barrel 5 rotates 90°. At this time, the empty receiving barrel 5 is directly below the discharge port 11, so that the plastic particles can be collected.

[0022] A second motor 3 is fixed to one side of the mounting frame 7, a rotating shaft 8 is installed between the mixing barrel 9 and the mounting frame 7, an output end of the second motor 3 is fixedly connected to the rotating shaft 8, a discharge port 11 is opened at the bottom of the mixing barrel 9, a solenoid valve is fixed to the discharge port 11, a third motor 4 is fixed to the top of the mixing barrel 9, and an output end of the third motor 4 is fixedly connected to the mixing shaft 14.

[0023] Specifically, when mixing is required, the third motor 4 is started, so that the third motor 4 drives the mixing shaft 14 to rotate, thereby driving the mixing rod 15 to rotate, so that the mixing rod 15 stirs the plastic particles, thereby mixing them, and then the second motor 3 is started, so that the second motor 3 drives the mixing barrel 9 to rotate, and the mixing barrel 9 is flipped, so that some plastic particles that cannot be stirred can contact with the mixing rod 15, thereby ensuring uniform mixing.

[0024] The baffle plate 13 is rotatably fitted in the feed port 12 , and a torsion spring is fixed between the baffle plate 13 and the feed port 12 .

[0025] Specifically, when it is necessary to add plastic particles into the mixing barrel 9, the feed pipe is inserted into the feed port 12, so that the feed pipe pushes the baffle 13 downward, thereby opening the feed port 12 and adding the material. When the adding is completed, the feed pipe is pulled out, and the baffle 13 is reset under the action of the torsion spring, and the feed port 12 is automatically blocked, and the adding is completed, thereby improving the feeding efficiency.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
