Description

Technical Field

[0001] The utility model relates to the technical field of feeders, in particular to a feeder for producing plastic pellets. Background Art

[0002] Plastic particles are the common name for plastic particles. They are the raw materials for storage, transportation and processing of plastics in the form of semi-finished products. Plastics are a type of polymer material. Ethylene, propylene, vinyl chloride, styrene, etc. can be produced using petroleum as raw material. The molecules of these substances can react with each other under certain conditions to generate compounds with large molecular weight, namely polymers. After the production of plastic particles, they need to be fed into other processing machines for the next step of processing.

[0003] For example, the prior art Chinese patent publication number "CN219381235U" provides a feeder for plastic pellet production, including a fixed frame, a placement box, a drainage duct and a baffle. The placement box is fixedly connected between the four fixed frames, a drainage duct is installed at the bottom of the placement box, the drainage duct is connected to the placement box, and a baffle is rotatably arranged inside the drainage duct. It also includes a first fixed plate, a motor and a rotating rod. The first fixed plate is fixedly connected to the inside of the placement box, and the motor is embedded in the first fixed plate. The rotating rod is fixed to the output shaft of the motor.

[0004] The device starts the motor, and the output shaft of the motor rotates to drive the rotating rod to rotate, so that the rotating rod stirs the plastic particles, improves the fluidity of the plastic particles, and enables the plastic particles to fully flow into the processing machine through the drainage pipe, thereby achieving a good feeding effect.

[0005] In the existing feeders for producing plastic pellets, the plastic pellets may be clumped together and accumulate in the feeder, causing the feeder to be blocked and unable to feed the plastic pellets. The plastic pellets cannot be fed smoothly. At the same time, the debris contained in the plastic pellets will be fed along with the plastic pellets, affecting the quality of subsequent products. The debris cannot be separated and discharged. Utility Model Content
