as shown in fig. 7; sliding grooves 7 are formed in two sides of the pool 1; the two ends of the drawing block 6 are slidably connected in the sliding groove 7, and a fourth spring 71 is fixedly connected between the two ends of the drawing block 6 and the inner wall of the sliding groove 7.
In operation, the drawing block 6 and the drawing plate 61 are both strip-shaped, the dimension of the drawing plate 61 is smaller than that of the drawing block 6, and the drawing plate 61 is made of a material which can be attracted by a magnet, such as iron; the sliding groove 7 or the drawing block 6 is arranged near the winding shaft 31 which is fully wound with the perfect elastic membrane 22, and the initial position of the drawing block 6 can be arranged at the maximum stroke of the lower clamping plate 48;
when the two winding shafts 31 stop rotating, namely when the elastic membrane 22 is replaced above the water tank 1, the first motor 4 is started, the lower clamping plate 48 is controlled to move above the drawing block 6, the second electromagnet 5 is controlled to be electrified to attract the drawing plate 61, the third spring 62 is stretched, the lower clamping plate 48 is matched with the drawing plate 61 to clamp the elastic membrane 22, the first motor 4 is started again, the lower clamping plate 48 moves in a direction away from the winding shaft 31 fully wound with the elastic membrane 22, the lower clamping plate 48 drives the drawing plate 61 and the drawing block 6 to move together under the action of the second electromagnet 5, the fourth spring 71 is stretched, namely the lower clamping plate 48 and the drawing plate 61 clamp the elastic membrane 22 to draw out a little more complete elastic membrane 22 to enter the water tank 1, then the pressing frame 24 presses the elastic membrane 22, the second electromagnet 5 is powered off, the drawing plate 61 is retracted under the action of the third spring 62, the drawing block 6 is reset under the action of the fourth spring 71, and the lower clamping plate 48 can move to the upper side of the drawing block 6 easily; the above process makes the elastic membrane 22 above the water tank 1 in a relaxed state, and the elastic membrane 22 is closer to the top cover 23 or contacts the top cover 23 to make the elastic membrane 22 in a relaxed state in cooperation with water pressure, so that after the strip-shaped material enters the water tank 1, the elastic membrane 22 extrudes the material, so that the elastic membrane 22 has enough allowance to be more attached to the surface of the material, and the cooling effect is increased.
As a specific embodiment of the present invention, the water outlet end of the water inlet 11 is disposed obliquely upward toward the elastic membrane 22.
In operation, the water outlet end of the water inlet 11 is obliquely upwards arranged towards the elastic membrane 22, and the water flow directly impacts the elastic membrane 22 to impact the heat accumulation part, so that the flow speed of the water flow at the heat accumulation part is increased, and the cooling is more facilitated.
