Description

Technical Field

[0001] The utility model relates to the technical field of plastic products, in particular to a plastic product processing and punching device. Background Art

[0002] Plastics refer to plastic (flexible) materials formed by processing or curing to form rigid materials, using high-molecular-weight synthetic resins as their primary component, along with appropriate additives such as plasticizers, stabilizers, flame retardants, lubricants, and colorants. Plastics are widely used and are essential components in home appliances, automobiles, mobile phones, personal computers, medical devices, and lighting appliances. With my country's economy achieving sustained and stable growth, industries such as home appliances, automobiles, mobile phones, personal computers, and medical devices have also experienced rapid development, benefiting from a favorable external environment. The development of downstream industries has further driven demand for plastics.

[0003] There are many types of plastic products. Based on their performance after heating, they are mainly divided into two categories: thermosetting plastics and thermoplastics. Based on their application, they can be divided into general-purpose plastics and engineering plastics. Based on their flammability, they are mainly divided into three categories: flammable plastics, combustible plastics, and flame-retardant plastics. Common thermosetting plastics include bakelite, electric jade, decorative panels, and unsaturated polyester plastics. Plastic sheets require punching during processing, but existing punching devices lack a mechanism to limit the position of the plastic sheets. This makes them prone to movement during processing, which can lead to waste. Furthermore, existing plastic product punching devices cannot be adjusted, reducing their practicality.

[0004] To this end, we propose a plastic product processing punching device. Utility Model Content
