Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

As shown in fig. 5 to 7, the invention provides a rib solar packaging film extrusion die head, which comprises an upper die 1, a middle die 2, a lower die 3 and connecting side plates 4 positioned on the left side and the right side, wherein a material B feeding runner 5 is arranged between the upper die 1 and the middle die 2, a material a feeding runner 6 is arranged between the middle die 2 and the lower die 3, the material B feeding runner 5 is in a tree-shaped divergent structure from back to front, the material B feeding runners 5 are arranged at the front end of the middle die 2 at intervals along the length direction of the middle die 2, a mixture extrusion channel 7 is formed between the upper die 1 and the lower die 3 on the front side of the middle die 2, and the rear end of the mixture extrusion channel 7 is communicated with the material a feeding runner 6 and the material B feeding runner 5.

On the basis of the scheme, the feed inlet of B material feedstock channel 5 is located the trailing flank middle part of mould 1 and

middle mould

2, 2 front ends of middle mould are the inclined plane by back to preceding downward sloping, B material feedstock channel 5 is the interval when flowing through on this inclined plane and arranges and 2 length direction in the middle of perpendicular, and here can be that equidistant interval is arranged, also can be that not equidistance interval is arranged according to the product demand, go up mould 1 and correspond 2 front end positions of middle mould and be the inclined plane structure that corresponds.

Specifically, the feed inlet of the material feeding runner 6 a is located in the middle of the rear side of the lower die 3 and the middle die 2, and the material feeding runner 6 a is uniformly distributed in the whole length direction of the lower die 3 when flowing to the front part of the lower die 3.

In addition, the edge of the material A feeding runner 6 of the lower die 3 is provided with a mounting groove 8 for mounting a sealing rubber strip, and after the sealing rubber strip is arranged at the position, the material A can be prevented from overflowing due to too large pressure in a die cavity.

In addition, the die lips of the upper die 1 and the lower die 3 are provided with oil temperature holes 9, so that the temperature of the die lips can be better controlled, and the production quality of products during extrusion is ensured.

Further, the connecting side plate 4 includes an upper mold large side plate 41 located on the left and right outer side surfaces of the upper mold 1, a small sealing side plate 42, a small sealing side plate 43 and a supporting side plate 44 located on the left and right outer side surfaces of the middle mold 2, and a lower mold large side plate 45 located on the left and right outer side surfaces of the lower mold 3.

When the rib solar packaging adhesive film is used, the material A enters the front part from the material A feeding runner 6 and then uniformly diffuses, the material B enters the front end inclined plane part of the middle die 2 from the material B feeding runner 5 and then reaches the front end inclined plane part of the middle die through the tree-shaped dispersing structure, the structure is uniformly distributed along the length direction of the middle die 2 at equal intervals, the material B is collected in the mixed material extrusion channel 7 and finally extruded from the die lips of the upper die 1 and the lower die 3, and the rib solar packaging adhesive film product with the structure shown in the figures 3 and 4 is obtained.
