Background

In the prior art, in the production field of single-sheet bagged cold compress products such as facial masks, eye masks, neck masks, foot masks and the like, the bad condition that no membrane sheet (hereinafter referred to as 'empty bag') exists in a packaging bag often occurs; this situation greatly reduces consumer's enjoyment of the product, trust in the brand, and creates a very poor consumer experience.

Based on the reasons, detection devices are developed in various industries to effectively avoid empty bags, and the detection principle is basically realized by using the thickness difference of film packaging bags with or without films.

The current thickness detection devices are roughly classified into two types:

the continuous detection structure comprises: the rolling bearing is connected with the encoder through the shaft and the coupler, and the angle change of the input shaft of the encoder is caused when the product passes through the rolling bearing, converted into an encoder pulse signal and fed back to the PLC;

(II) intermittent detection

The cylinder pushes the product to be extruded onto a sensor (such as an electronic scale sensor), and the pressure change of the electronic scale sensor is further converted into a digital signal;

above two kinds of modes have reached the purpose of monitoring thickness, detection empty bag basically, but the accuracy is not high, and structural stability is not high simultaneously, takes place easily not hard up, warp and further has reduced the accuracy, often appears misjudgement, leaks to put the defective products.
