Detailed Description

Example 1

As shown in fig. 1, the utility model discloses a novel LDPE tri-regulation double-tuyere, which comprises a lower cover 1, an upper cover 2, a lower wind lip 3, a wind core 4, a large adjusting nut 5, an upper wind lip 6 and a wind protection lip 7; the lower cover 1 is in a circular ring shape, a plurality of screw holes are formed in the edge of the inner side of the lower side surface of the lower cover, and threads are formed in the inner wall of the lower cover; the upper cover 2 is in a ring shape, is buckled and installed on the lower cover 1, is fixed with the lower cover 1 by a matched screw, and is provided with threads on the inner side surface; the leeward lip 3 is assembled on the lower side of the lower cover 1 by a screw; the wind core 4 is assembled on the threads of the inner wall of the lower cover 1, and a gap is formed between the wind core and the lower wind lip 3; the large adjusting nut 5 is annular and is matched and installed on the threads on the inner wall of the upper cover 2; the windup lip 6 is arranged on the inner side of the large adjusting nut 5, is fixed by a screw, and forms a gap with the wind core 4; the wind-protecting lip 7 is arranged at the top end of the upper wind lip 6. A cavity is formed between the lower cover 1 and the upper cover 2 to form a cross air path, and air is blown to the cavity from the right external pipeline to provide stable air flow to the inside; the upper side of the outer wall of the wind core 4 is provided with a circle of inward grooves, and a plurality of round holes penetrating the wind core 4 and connecting with the gaps on the upper side and the lower side of the wind core 4 are arranged in the grooves to communicate the gaps on the upper side and the lower side of the wind core 4; the upper side of the down wind lip 3 is provided with an annular bulge, the lower side of the wind core 4 is provided with an annular groove corresponding to the annular bulge, and when the down wind lip is pressed tightly, the gap at the lower side of the wind core 4 can be sealed, and the wind path at the lower side of the wind core is cut off.

The working principle is as follows: when the LDPE film cooling device is used, after the upper cover 2 is fixedly arranged on the lower cover 1, the lower wind lip 3, the wind core 4, the large adjusting nut 5 and the upper wind lip 6 are arranged in sequence from bottom to top, and the positions of the wind core 4, the large adjusting nut 5 and the upper wind lip 6 are adjusted according to LDPE films required to be cooled, so that the gaps on the upper side and the lower side of the wind core 4 are adjusted. The wind introduced from the external wind path on the right side is divided into two paths after flowing through the 'V' -shaped wind path between the lower cover 1 and the upper cover 2, and one path blows into the center from the gap between the wind core 4 and the upper wind lip 6; the other path of the air is blown into the center through a groove on the outer wall of the air core 4 and a round hole through a gap between the downwind lip 3 and the air core 4; finally, after the material is fed from the center, an air passage can be started for rapid cooling, the yield is greatly improved, and the blown LDPE film is uniform in thickness, bright in transparency and free of crystal points.
