[0002] Plastic products are indispensable products in people's life, such as tableware, tables and chairs, vehicle supplies, toys, etc. The traditional plastic coloring adopts a direct spraying way, which is relatively simple, but the coloring effect is not good enough and is easy to color off. Therefore, people have invented a plastic color matching machine, which mainly mixes plastic raw materials (plastic particles) and color powder in a certain proportion, then stirs them, so that the color powder adheres to the surface of the plastic raw materials, and then they are delivered together to the barrel of an injection molding machine for heating, stirring and mixing. The plastic color matching machine mainly consists of a plastic raw material feeding device, a color powder feeding device, a mixing and stirring device, a storage device and other structures. The storage device includes a storage tank, a stirring tank of the mixing and stirring device is arranged at the upper part of the storage tank, a storage valve is arranged between the stirring tank and the storage tank, the lower part of the storage tank is connected to the barrel of the injection molding machine, and a barrel valve is arranged between the storage tank and the barrel. After the plastic raw materials and color powder are fully stirred and mixed in the stirring tank, they are delivered to the storage tank for storage through the storage valve, and then delivered to the barrel through the barrel valve. When there is enough material in the barrel, the barrel valve is closed. However, after the mixing and stirring device completes the mixing, the mixed plastic raw materials will continue to be fed into the storage tank. The existing method usually sets a transparent observation window on the storage tank, and workers need to observe whether the storage tank is full of mixed plastic raw materials through the observation window. If the storage tank is full, the workers need to manually close the plastic raw material feeding device, the color powder feeding device and the mixing and stirring device to stop feeding. Workers need to keep an eye on the equipment, which is labor-intensive. SUMMARY

[0003] The utility model aims at overcoming the shortcomings of the prior art, providing a plastic color matching machine's storage sensing device which senses the mixed material in the storage tank, reduces the labor intensity of workers and has a simple structure.

[0004] The technical scheme of the plastic color matching machine's storage sensing device of the utility model is as follows: a machine body is provided, an inlet hopper is arranged at the upper part of the machine body, a storage tank is arranged on one side of the machine body, a stirring tank is arranged above the storage tank, a valve structure is arranged between the storage tank and the stirring tank, a cover plate is arranged on the stirring tank, an inlet is formed in the cover plate, the lower opening of the inlet hopper corresponds to the inlet, the inlet communicates with the inside of the stirring tank, a support is arranged on the inner wall of the storage tank, a fixed shaft is arranged in the support, a rotating piece is arranged on the fixed shaft, connecting ears are arranged on the upper part of the rotating piece, shaft holes are formed in the connecting ears, the connecting ears are rotationally connected with the fixed shaft through the shaft holes, a magnet is arranged on one side of the lower part of the rotating piece, a magnetic induction sensor is arranged on the machine body and corresponds to the magnet.

[0006] Further, the valve structure comprises a storage valve arranged at the lower opening of the stirring box, and the storage valve is driven to rotate by a storage motor.

[0007] The beneficial effect of the storage sensing device of the plastic color matching machine is that: the magnet is arranged on one side of the rotating piece, the magnet and the magnetic induction sensor of the outer wall of the storage tank are inductively matched, when the storage tank is full of mixed materials, the mixed materials can drive the rotating piece and the magnet to rotate, so that the magnet is separated from the inductive matching with the magnetic induction sensor, which proves that the storage tank is full of mixed materials, the stirring box stops mixing and stirring, and the storage valve is automatically closed, otherwise, it proves that the mixed materials in the storage tank are insufficient, the stirring box continues to mix and stir, and the mixed materials are transported to the storage tank, so that workers do not need to monitor the equipment for a long time, thereby effectively reducing the labor intensity of workers.
