Detailed Description
The following describes the technical solution of the present utility model further by means of specific embodiments with reference to fig. 1-2.
The high-efficiency cooling device for the PVC decorative film shown in fig. 1 comprises: the PVC decorative film packaging machine comprises a water tank 1, a first guide roller 3, a second guide roller 2, a third guide roller 4, an air knife, a first guide plate 15, a second guide plate 11 and a controller 6, wherein the first guide roller 3 is arranged at the top of one side of the water tank 1, the second guide roller 2 is arranged in the water tank 1 and positioned below the front side of the first guide roller 3, the third guide roller 4 is arranged at the top of the water tank 1 and positioned above the second guide roller 2, the PVC decorative film 9 downwards enters the water tank 1 through the first guide roller 3, upwards goes out of the water tank 1 after passing through the second guide roller 2, finally goes out through the third guide roller 4 (a winding frame is arranged at the front for winding the PVC decorative film), and is conveyed in a vertical state between the second guide roller 2 and the third guide roller 4.
In this embodiment, the water tank 1 is filled with cooling water for flooding the second guide roller 2, and the PVC decoration film 9 is cooled by water when passing through the second guide roller 2, so that the efficiency is high.
The first guide plate 15 and the second guide plate 11 are vertically arranged in the water tank 1 and horizontally and longitudinally distributed below the third guide roller 4 at intervals, namely, two sides of the vertical path of the PVC decorative film 9 in FIG. 1. As shown in fig. 2, air knife holders 13 are respectively disposed at the top of the first air deflector 15 and the top of the second air deflector 11, and the air knives 12 are disposed on the air knife holders 13 and are externally connected with a compressed air supply pipeline. The air outlet of the air knife 12 is obliquely downwards directed to the gap between the first guide plate 15 and the second guide plate 11, and air flow is obliquely downwards blown to two sides of the PVC decorative film 9, so that the PVC decorative film 9 is dried and cooled. In this embodiment, the air curtain width of the air knife 12 is larger than the width of the PVC decorative film 9, so as to ensure the coverage of the PVC decorative film 9 surface by the air curtain.
The edges of the left side and the right side of the first guide plate 15 and the second guide plate 11 can be welded and fixed with the inner wall of the water tank 1, so that the air tightness is improved, and an air flow channel is formed between the first guide plate 15 and the second guide plate 11. When the air flow moves downwards along the channel between the first guide plate 15 and the second guide plate 11, the two sides of the PVC decorative film are continuously air-dried, and when the air flow meets the liquid level of cooling water, the heat of the cooling water can be taken away, so that the cooling water is cooled.
