Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of home appliance product packaging, more specifically, especially relates to an automatic pearl wool pasting equipment. BACKGROUND

[0002] With the improvement of the appearance process requirements of home appliances (such as washing machines, refrigerators, etc.), surface protection has become an indispensable link in the production link. Pearl wool (EPE) is widely used in the packaging and protection of the surface of electrical appliances due to its light weight, excellent cushioning performance and low cost, especially in the key area and panel prone to scratching. In the traditional process, the pasting of pearl wool mainly relies on manual operation: workers need to manually cut materials, apply glue, position and press. However, this method has significant defects: 1. Low efficiency: the speed of manual operation is limited by the worker's proficiency, which is difficult to match the rhythm of the automatic production line and becomes a bottleneck of production; 2. Poor consistency: the pasting position is easy to shift, and the glue layer is uneven, resulting in poor adhesion or air bubbles in some areas, affecting the protection effect; 3. High cost: high labor demand and high material waste rate increase production costs in the long run. Although existing automated equipment attempts to solve the above problems, it still has limitations: conventional equipment such as specific home appliances has poor adaptability and insufficient precision, and pearl wool is prone to displacement or wrinkling during transfer; the pasting effect is poor, and there is a lack of pressing and flattening mechanism, which is prone to edge lifting or local delamination after pasting.
