Technical Field

[0001] The invention relates to the technical field of centrifuges, and in particular to a centrifugal cleaning flexible plastic disc fixing device and a centrifugal cleaning machine thereof. Background Art

[0002] Centrifugal cleaning equipment is a common industrial cleaning equipment, widely used in manufacturing, automotive industry, aerospace and other fields. It projects objects or parts into the cleaning agent through rotational motion, and uses centrifugal force and friction to achieve the cleaning effect.

[0003] According to Chinese patent CN215844748U, a centrifugal cleaning machine is disclosed. The fixing fixture of the equipment is fixedly connected to the cleaning disc by screws. However, the gap in the slot of the micro product will cause a gap between the two layers of hard plastic discs. If the two layers of hard plastic discs are not tightly fitted, the product will be thrown out from between the two layers of hard plastic discs or the product will be crushed due to rotation. Therefore, some manufacturers will use elastic components to clamp the material disc and press the material disc. However, in the actual working process, the elastic force of the new elastic component is relatively large, and the material disc is clamped too tightly, which makes it difficult to take and put the material disc. After long-term use, the elastic force of the elastic component decreases, and the material disc is clamped too loosely, causing the product to fall off during the cleaning process.

[0004] Therefore, it is necessary to develop a centrifugal cleaning flexible plastic disc fixing device and a centrifugal cleaning machine thereof to solve the above problems. Summary of the invention
