[0002] Plastics are polymer compounds made of monomers through addition polymerization or condensation polymerization, commonly known as plastics or resins. They can freely change their composition and shape, and are composed of synthetic resins and additives such as fillers, plasticizers, stabilizers, lubricants, and colorants. Plastics are widely used in all aspects of industry and life, and the demand is huge. As an important equipment for producing plastics, plastic wire drawing machines are widely used in chemical companies. The existing plastic wire drawing machines have poor cooling and molding effects on plastics during use, are not environmentally friendly, and waste resources. Secondly, the processed and cooled plastics are not dried, resulting in water droplets on the collected rolled plastics, which is inconvenient to collect and store.

[0003] For example, a wire drawing machine for plastic processing disclosed in Chinese patent publication number CN214188337U dissipates heat internally by means of a heat dissipation fan driven by a motor, discharges internal hot air through an exhaust port, draws water out of a water tank through a water pump, rapidly cools water through a condenser, and then flows into the water tank through a water pipe, thereby achieving internal water circulation, saving resources, having an environmentally friendly effect, improving cooling and molding efficiency, and enhancing molding quality. The processed and molded plastics are dried through a drying device for easy collection and storage, thereby enhancing the overall processing quality.

[0004] The existing technology has the following problems:

[0005] However, the above device needs to perform molding operations on high-temperature drawn plastics during the process of plastic drawing. The cooling molding efficiency of the extruded plastics by the above device is only achieved by rapid cooling through the condenser, and it is impossible to perform special shaping of the drawn plastics.
