Description

Technical Field

[0001] The invention belongs to the technical field of toy polishing, and in particular relates to a polishing device for manufacturing toys made of degradable raw materials. Background Art

[0002] Toys refer to items that can be used for playing. Playing with toys is often used as a way of educating and entertaining in human society. They can be natural objects, such as sand, stones, twigs and other non-artificial things, or they can be artificial toys purchased on the market. Artificial toys are usually made of degradable materials for environmental protection. In order to prevent children from accidentally chewing on them and affecting their health, food-grade degradable raw materials are gradually being widely used.

[0003] During the production process of toys, in order to achieve a smooth surface, a grinding device is needed to grind the surface. The currently used grinding device places the toy on a work platform when in use. By turning the rotating handle, the second threaded rod rotates to drive the limit plate to move and clamp the toy. The drive motor is controlled to drive the first threaded rod to rotate, and the work platform is brought to the specified position. The hydraulic device is controlled to start, and the air pressure reaches the hydraulic cylinder through the hydraulic pipeline. The hydraulic rod drives the mounting plate to move downward to the specified position, and the electric motor is controlled to start. The electric motor starts to drive the grinding wheel to grind the plastic toy. However, the above-mentioned grinding device needs to repeatedly adjust the position of the toy when grinding different positions, which is not only inconvenient to load and unload, but also takes a long time to position. The toy moves horizontally and the grinding wheel moves in the height direction. Although the grinding work can be achieved, there are situations where grooves cannot be polished, and the grinding waste is easy to splash on the surface of the toy, and its surface needs to be cleaned later.
