Abstract

The invention relates to a nose-bridge-free protective mask and a high-speed rotary die cutting production process and equipment thereof. The protective mask comprises a first mask body, a second maskbody, first ear belt cloth and second ear belt cloth, wherein the first mask body and the second mask body are symmetrically designed and the first ear belt cloth and the second ear belt cloth are symmetrically designed. The nose-bridge-free protective mask is produced by taking a high-speed circular knife machine as a main machine; the mask is divided into two symmetrical mask bodies and ear belt cloth, and the mask bodies and the ear belt cloth are compounded and subjected to hot-pressing shaping. The ear belt cloth is locally embedded and is bonded with the mask body through one-time hot pressing; then, the two mask body material strips are in symmetrical hot-pressing connection; and finally die cutting is carried out to obtain a mask finished product. The whole production process is smoother and faster; traditional ultrasonic welding operation is abandoned, the mask production efficiency can be greatly improved, the operation speed can reach 60 m/min, the number of masks convertedcan exceed 600 pcs/min; equipment is greatly simplified, the equipment cost is also greatly reduced, and automatic operation can be achieved in the whole production process.

Description

Technical field: [0001] The invention relates to the technical field of mask production, in particular to a protective mask without a bridge of the nose and its high-speed rotary die-cutting production process and production equipment. Background technique: [0002] As an important protective isolation product, masks play an important role in people's daily life and industrial production. Masks have different classifications and different standards according to the occasions and environments in which they are used. Existing protective masks are usually produced by ultrasonic welding, which will cause pauses during ultrasonic welding, which will affect production efficiency; moreover, the production equipment is relatively complicated and the cost is high. Invention content: [0003] The purpose of the present invention is to overcome the above-mentioned weak point of prior art, a kind of protective mask without bridge of the nose and its high-speed rotary die-cutting prod...
