Impact-resistant PE foaming composite material

The utility model provides a digital printing ink detection device, and belongs to the technical field of ink detection. The EPE pearl wool solves the problems that existing EPE pearl wool is poor in impact resistance and tensile property and prone to deformation under the condition of external force. According to the impact-resistant PE foaming composite material, a buffering mechanism is further connected between an upper pearl wool base layer and a lower pearl wool base layer, the buffering mechanism comprises a first buffering strip and a second buffering strip, grooves are formed in the lower surface of the upper pearl wool base layer and the upper surface of the lower pearl wool base layer, and the first buffering strip is connected into the grooves through glue; the two first buffer strips lean against each other, a cavity is formed in the middle of the shape of the two first buffer strips, the second buffer strips are located on the side portions of the first buffer strips, the two ends of the second
