AI Technical Summary
In existing plastic cup heat shrink sleeve equipment, the airflow organization in the heating cavity is singular in the linear heating mode, resulting in poor heat conduction efficiency, uneven temperature gradient distribution, and easy generation of quality problems such as wrinkles, bubbles, or local loosening.
It employs support components, drive components, heat shrink components, and air circulation components. An effective circulating airflow field is formed through heating tanks, air inlets, and circulating motors. Combined with a movable placement platform and multi-layer heating boxes, it ensures uniform heat distribution.
It improves heat conduction efficiency, ensures uniform shrinkage of heat-shrink film, reduces quality problems such as wrinkles, bubbles or local loosening, and significantly optimizes the heat-shrink labeling effect of plastic cups.
