Abstract

The invention discloses a mask making machine and a pay-off mechanism thereof. The pay-off mechanism is applied to the mask making machine. The mask making machine is equipped with a processing mechanism for processing masks. The pay-off mechanism comprises a support, a sensing assembly and a driving device. The support is used for supporting a roller for winding a mask thread. The movable end ofthe mask thread is pulled to the processing mechanism for mask processing. The sensing assembly is disposed between the roller and the processing mechanism and is used for sensing a drooping state andstraightening state of the portion, located between the support and the processing mechanism, of the mask thread. The driving device is disposed on the support and is used for driving the roller to rotate so as to increase the pay-off length when the sensing assembly senses that the portion, located between the support and the processing mechanism, of the mask thread is straightened and stoppingcontrolling the roller to rotate so as to stop increasing the pay-off length when the sensing assembly senses that the mask thread droops to the ground. By means of the technical scheme, the problemsthat in the mask processing process, the pay-off length is difficult to control and mask processing efficiency is low are solved.

Description

technical field [0001] The invention relates to the technical field of mask production equipment, in particular to a mask machine and a wire-feeding mechanism thereof. Background technique [0002] A mask is a hygienic article worn on the nose and mouth to filter the air entering the nose and mouth. It usually includes a mask main body for covering the nose and mouth and a mask line for fixing the main body of the mask to the nose and mouth of the user. In the process of mask production, it is necessary to use the pay-off mechanism to transport the mask line to process the mask line on the main body of the mask, and the raw material of the mask line for mask processing is usually a long strip wound on a reel. It is easy to cause the mask thread to be stretched and damaged due to insufficient pay-off length, or the mask thread to be entangled and knotted due to too long pay-off length, that is, during the mask processing process, the pay-off length is difficult to control, ma...
