Description

A plastic product edge grinding device

Technical Field

The utility model relates to the technical field of grinding devices, in particular to a device for grinding corners of plastic products.

Background Art

Grinding is a type of surface modification technology, which generally refers to a processing method that uses rough objects to change the physical properties of the material surface through friction. The main purpose is to obtain a specific surface roughness. In industrial production, we will see that the cross-section of cut plastic products has more or less rough and uneven surfaces on the surface of some plastic products and equipment. Such plastic products and equipment will have a greater impact on subsequent processing and production, so these plastic products and equipment must be polished.

According to the search, Chinese patent literature, announcement number: CN105798717B, discloses a plastic product corner grinding device. By setting it so that workers do not need to hold metal equipment during the grinding process, the safety guarantee during the grinding process is increased, the work efficiency is improved, and human resources are saved, thereby reducing the labor cost required for production. The use of shock-absorbing plates reduces the vibration of the grinding device, thereby reducing the noise in production and reducing the harm to workers during the production process. However, the grinding structure of the device cannot be moved and lacks flexibility. After the plastic product is fixed, it cannot be adjusted to a suitable position. When the grinding device or the plastic product is moved again for polishing and grinding, it is easy to cause shaking. The grinding equipment or parts are poorly stable, and it is time-consuming and labor-intensive, with low work efficiency. The sanding machine itself cannot adjust the angle, and the sanding machine has a single angle and low quality.
