Mask machine folding ear belt forming mechanism and forming method thereof

Abstract

The invention discloses a mask machine folding ear belt forming mechanism and a forming method thereof. The mask machine folding ear belt forming mechanism comprises an ear belt fabric uncoiling device, a tension swing rod assembly, an active clamping and conveying device, a conveying wind scoop, a slitting knife box and a hot-pressing knife box, the slitting knife box is located above the hot-pressing knife box, the hot-pressing knife box and the slitting knife box are connected with each other, the tension swing rod assembly is located between the ear belt fabric uncoiling device and the active clamping and conveying device and used for detecting and adjusting the conveying tension of ear belt fabric, and the active clamping and conveying device is located between the tension swing rod assembly and the conveying wind scoop and used for adjusting the uncoiling speed of the ear belt fabric uncoiling device. According to the mechanism, the hot-pressing knife box and the slitting knife box are integrated together and are connected and matched with each other, so that ear belts can be quickly transferred to the hot-pressing knife box and hot-pressed to a mask main body after being formed on the slitting knife box, the alignment precision of the ear belts and a mask main body is ensured, the product quality is ensured, the hot-pressing speed of the ear belts can be ensured, and the production efficiency is ensured.

Description

technical field [0001] The invention relates to parts of a mask machine, in particular to a forming mechanism for folding ear straps of a mask machine and a forming method thereof. Background technique [0002] As one of the parts of the mask, the earbands are usually cut out with the earband forming knife box first, and then heat-pressed onto the main body of the mask with the earband heat-pressing knife box. The earband forming knife of a conventional mask machine The case and the earband heat-pressing knife box are usually designed separately. After the earband is formed, a special conveying part is required to transport it to the earband heat-pressing knife box for heat pressing, which will not only affect the alignment accuracy between the earband and the mask body , thus affecting the product quality, but also affecting the heat pressing speed of the ear straps, thus affecting the production efficiency. Contents of the invention [0003] In order to solve the defect...
