Therefore, people invented a plastic color matching machine, which mainly mixes plastic raw materials (plastic particles) and color powder in a certain proportion and stirs them, so that the color powder adheres to the surface of the plastic raw materials, and then transports them together to the barrel of the injection molding machine for heating, stirring and mixing. The plastic color matching machine is mainly composed of a feeding device for plastic raw materials, a powder feeding device for color powder, a mixing and stirring device, a storage device and other structures, wherein the feeding device for plastic raw materials includes a feeding hopper and a feeding valve, and the feeding valve is driven by a motor to rotate and open or close. The rotating shaft of the existing feeding valve is usually connected to the feeding hopper, that is, the feeding valve, the feeding hopper, and the motor are assembled together. When the feeding hopper is to be disassembled for cleaning, the feeding hopper, the feeding valve, and the motor need to be disassembled together, and then the motor and the valve are disassembled, and the installation and disassembly are very troublesome.
