Description

Technical Field

[0001] The invention relates to the technical field of shoe material forming, in particular to a shoe material groove roller cutting rapid forming method and a forming device thereof. Background Art

[0002] Shoes are essential clothing for people's activities. Traditional sports footwear products include two main components, the upper and the sole structure. The upper provides a cover for the foot, which can comfortably accommodate the foot and firmly position the foot relative to the sole structure. The sole structure is fixed to the lower part of the upper and is usually placed between the foot and the ground. In addition to attenuating the reaction force of the ground, the sole structure can also provide grip and impart stability, for example. Some common soles in the market usually include an outsole and a midsole. The outsole is mainly in contact with the ground, and it is mainly non-slip and wear-resistant. The midsole is set on the outsole, and it is mainly required to have a certain degree of softness to make the shoes more comfortable to wear. Some functional blocks are often embedded in the midsole to increase the function of the midsole, such as shock-absorbing blocks, lightweight blocks, elastic blocks, air cushion blocks, etc. It is necessary to set grooves on the surface of the midsole to embed these functional blocks. Often, insoles are also padded in the shoes to make the user's feet comfortable and protect the feet. For sports shoe insoles, grooves are often set at the insoles corresponding to the heels to form a wrap to protect the heels and increase stability. The grooves on the midsole or insole are generally made by mold stamping. The stamping equipment is complicated and continuous production cannot be carried out. In addition, the mold structure is complicated, the insole or midsole is easy to be stuck inside the mold, and there are many manual intervention links, resulting in low production efficiency. Moreover, the surface of the groove after stamping is prone to burrs, affecting comfort. Summary of the invention
