Problems solved by technology

However, after the hot-melt adhesive applicator starts operating, the desired amount of hot-melt adhesive may not be applied during the process of reaching the specified speed or decelerating to stop, resulting in problems such as uneven application.
Therefore, qualified products cannot be produced, resulting in waste of materials

Embodiment 1

[0037] Embodiment 1: refer to Figure 1 ~ Figure 4 , the hot melt adhesive applicator 10 according to Embodiment 1 of the present invention will be described.

[0038] figure 1 It is a block diagram of the hot melt adhesive applicator 10. like figure 1 As shown, in the hot melt adhesive application equipment 10, in order to make the outer peripheral surfaces 16s, 18s of the printing roller 16 and the pressing roller 18 approach each other, the printing roller 16 and the pressing roller 18 are arranged adjacently. The printing roller 16 and the press roller 18 rotate in reverse and synchronously with each other as indicated by arrows 16r and 18r.

[0039] The material to be coated 72 in the form of a belt is conveyed along the outer peripheral surface 18 s of the pressing roller 18 . The material to be applied 72 is arranged along the outer peripheral surface of the press roller 18 , moves as indicated by arrows 72 p and 72 q as the press roller 18 rotates, and passes bet...

Abstract

The invention relates to a hot melt adhesive coating device and a hot melt adhesive coating method and provides a hot melt adhesive coating device which can inhibit hot melt adhesive coating amount change even if the sending speed of a material to be coated is changed and a hot melt adhesive coating method. The technical scheme is that a gap 13 is arranged between an adhesion roller 14 and a gap forming element 12. Molten hot melt adhesives 4 are accumulated above the gap 13. Hot melt adhesives 5a going through the gap 13 and adhering to the adhesion roller 14 are coated on a printing roller 16, and then are coated on a material 72 to be coated. The gap forming element 12 moves towards the direction separating from the adhesion roller 14 according to the rotation speed of the adhesion roller 14 to change the gap 13.

Description

technical field [0001] The invention relates to a hot-melt adhesive coating device and a hot-melt adhesive coating method, in particular to a hot-melt adhesive coating equipment and a hot-melt adhesive coating method for continuously coating a strip-shaped material to be coated. Background technique [0002] There are various proposals for hot-melt application equipment for continuously applying hot-melt adhesive to a strip-shaped material to be coated. [0003] like Figure 5 The shown hot-melt applicator applies hot-melt adhesive for bonding absorbent pads on the back sheet 111 when manufacturing the disposable urine pad. The hot-melt applicator utilizes a hot-melt supply part 100 to apply hot-melt glue on a printing roller 102 on which a silicone plate is fixed. In the hot-melt supply part 100, the adhesive roller 101a and the gap adjustment roller 101b are arranged after setting a gap, and the hot-melt adhesive 4 that is hot-melted in the gap can be accumulated. Throug...
