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 above-mentioned scheme, the feed inlet of B material feeding runner 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 front downward sloping, B material feeding runner 5 is the interval when flowing through on this inclined plane and arranges and 2 length direction of perpendicular middle mould, and here can be that equidistant interval is arranged, also can be that not equidistant 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 A feeding runner 6 is located in the middle of the rear side faces of the lower die 3 and the middle die 2, and the material A feeding runner 6 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 mounting groove, the material A can be prevented from overflowing due to too high 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 mould is used, the material A enters from the material A feeding runner 6 and then enters the front of the mould to be uniformly diffused, the material B enters from the material B feeding runner 5 and then reaches the inclined plane part at the front end of the middle mould 2 through the tree-shaped divergent structure, the inclined plane part is in a structure uniformly distributed at equal intervals along the length direction of the middle mould 2 and is converged at the mixed material extrusion channel 7, and finally the mixed material is extruded from the mould lips of the upper mould 1 and the lower mould 3, so that the rib solar packaging adhesive film product with the structure shown in the figures 3 and 4 is obtained.
