The glue passing film channel plate 7 is uniformly provided with a group of heating through holes 7-1 along the axial direction of the extrusion forming roller 5. Because the heating device 6 is adopted to directly heat the adhesive passing film 9, the extrusion forming roller 5 is a cold roller, and the defect caused by continuously heating the extrusion forming roller 5 is effectively overcome. The arrangement position of the heating through hole 7-1 corresponds to the heating position of the heating device 6, and the width of the heating through hole 7-1 corresponds to the designed heating area, thereby being beneficial to heat conduction and avoiding heating the whole adhesive film 9. An exhaust channel is formed between unheated adhesive passing films 9, so that air between the adhesive passing films 9 and adhesive passing objects is exhausted when the extrusion forming roller 5 extrudes.

In order to prevent the adhesive film 9 from being stuck in the adhesive applicator, the present embodiment preferably further includes a pair of parallel separators 8. The partition plate 8 is uniformly provided with a group of grooves 8-1 for the extrusion forming roller 5 to pass through along the axial direction of the extrusion forming roller 5. The plate between adjacent slots 8-1 forms ribs 8-2. The preferred separator in this embodiment is a metal separator having a thickness between 0.8mm and 1mm and ribs 8-2 having a width of 0.3mm. A pair of spacers 8 are provided between the pair of extrusion rolls 5. The extrusion forming roller 5 is provided with clamping seams 5-1 corresponding to the ribs 8-2 of the partition plate 8. The rib 8-2 is embedded into the clamping slot 5-1 and is clamped with the clamping slot 5-1. When assembling, the clamping slot 5-1 of the pair of extrusion forming rollers 5 is aligned with the rib 8-2 on the partition board, the rib 8-2 is inserted into the clamping slot 5-1, and the extrusion forming rollers 5 penetrate out of the grooves 8-1 of the partition board 8. The rib 8-2 is wrapped in the extrusion roller 5 by using the rubber elasticity of the extrusion roller 5, and the partition 8 and the extrusion roller 5 form an integral structure. For ease of processing, the preferred ribs 8-2 of this embodiment are replaced by cords 8-4. The baffle plate 8 is provided with an integral slot 8-1. The partition 8 is provided with a set of cord fasteners 8-5 on either side of the slot 8-1. The cord 8-4 is fixedly mounted to the spacer 8 by a cord fastener 8-5. The cords 8-4 divide the grooves 8-1 into a plurality of areas along the radial direction of the extrusion roll 4. By adopting the mode, only a notch is needed to be formed on the partition plate 8, so that the processing difficulty of the partition plate 8 is reduced. The slot 8-1 is divided into several sections by the cord 8-4, and the arrangement of the cord 8-4 may be one cord wound around the slot 8-1 or a plurality of parallel cords arranged on the slot 8-1.
