Multifunctional automatic adhesive application device

A multifunctional automatic adhesive application device is formed as follows: an adhesive storage barrel I is fixed on a support frame and adopts a structure including inner and outer sandwich layers, an inner barrel adopts an adhesive storage container, a stirring motor is mounted at the top of the adhesive storage container, 25-30 DEG C thermal water is fed into the sandwich layers, a temperature sensor is further mounted between the sandwich layers, the adhesive storage container and the steeping vat are connected via a pipeline I, the fixed position of the adhesive storage barrel I is higher than the steeping vat, the adhesive storage container and the adhesive storage barrel II are connected via a pipeline II arranged in the adhesive storage barrel II, a liquid-level controller is mounted in a small semi-enclosed space at one end of the steeping vat and controls automatic adhesive replenishment of an electrically operated valve, and an air powered pump replenishes liquid adhesive of the adhesive storage container. The multifunctional automatic adhesive application device overcomes the disadvantages of low efficiency of artificial adhesive replenishment and poor quality of liquid adhesive caused by the influence from temperature, concentration and time in the non-woven fabric manufacturing technology, and integrates the functions of stirring, thermal insulation and automatic adhesive replenishment into a whole, thereby being suitable for the manufacturing technology of all non-woven fabric series.
