Description

Technical Field

[0001] This utility model relates to the field of plastic production technology, specifically to a mixer for producing plastic particles. Background Technology

[0002] Plastic pellets, a common name for plastic granules, are raw materials used for storing, transporting, and processing plastics into semi-finished products. Plastics are a class of polymer materials, derived from petroleum, which can produce ethylene, propylene, vinyl chloride, styrene, etc. The molecules of these substances can react with each other under certain conditions to form compounds with very high molecular weights, i.e., polymers. Plastic pellets are classified into polystyrene, modified polystyrene, polypropylene, polyethylene, and modified polyethylene, among others. During the production and processing of plastic pellets, they are generally stirred using a mixer.

[0003] Chinese patent (CN210415055U) discloses a plastic particle mixer, including a support plate, a support device, a barrel, and an auger. A bracket is fixed to the top of the support plate. The bracket is welded from a set of horizontal plates and two sets of vertical plates. Hydraulic cylinders and clamps are fixed to the facing side walls of the two sets of vertical plates. Clamping plates are fixed to the tops of the piston rods of the two sets of hydraulic cylinders. A support device is arranged between the two sets of hydraulic cylinders. The barrel is fixed inside the support device. A discharge valve is fixed to the bottom of the barrel. The top wall of the barrel has a flange. A motor is fixed to the top of the horizontal plate of the support. The output end of the motor is connected to a stirring shaft via a coupling. One end of the stirring shaft passes through the horizontal plate of the support, and two sets of cleaning components and one set of auger blades are fixed to the outer wall of the stirring shaft. This plastic particle mixer facilitates the inspection and replacement of the stirring shaft and auger blades, and the cleaning of the inner wall of the barrel, but makes the mixer less convenient to use.

[0004] However, the aforementioned technologies have some drawbacks. For example, existing plastic particle mixers generally use conventional mixing blades, resulting in insufficient mixing efficiency. After mixing plastic particles, residues are easily left at the mixer's outlet, requiring manual cleaning, which makes the plastic particle mixer inconvenient to use. Utility Model Content
