[0002] A cooler is a type of heat exchange equipment used to cool fluids, usually using water or air as a coolant to remove heat. It can be mainly divided into shell and tube coolers, plate coolers and air-cooled coolers. Coolers are heat exchange devices commonly used in industrial sectors such as metallurgy, chemical industry, energy, transportation, light industry, and food.

[0003] A search revealed that Chinese Patent Publication No. CN217047173U discloses a cooling and tensioning device for processing plastic film, comprising a horizontally arranged cooling roller, with both ends of the cooling roller sealed and axially symmetrically connected to each other by connecting rotating pipes. The connecting rotating pipes on both sides are connected by an axially arranged spiral pipe, and the spiral pipe is in contact with the inner circumferential wall of the cooling roller. A bearing is axially sleeved on the connecting rotating pipe, and the bottom of the bearing is vertically supported by a lifting and positioning mechanism. The outer end of the connecting rotating pipe is rotatably sealed with a connecting elbow, and the lower end of the connecting elbow is sealed and connected to the inlet and outlet water pipes. This utility model allows coolant to continuously flow through the surface of the cooling roller, maintaining a uniform cooling effect on the plastic film.

[0022] The upper surface of the cooling box 1 is hingedly connected to a box cover via a door hinge, and a sealing gasket is fixed to the lower surface of the box cover.

[0023] In this embodiment, there are three conveying rollers 2, which are evenly distributed between the inner front wall and the inner back wall of the cooling box 1. A No. 2 motor 5 is fixed on the back of the cooling box 1. The output shaft of the No. 2 motor 5 passes through the cooling box 1 and extends to the inner cavity of the cooling box 1 and is fixed to the conveying roller 2 at the far right.

[0024] See also Figure 3In order to quickly reduce the temperature of the coolant, the circulation mechanism 4 in this embodiment includes a liquid storage tank 401 fixed to the lower surface of the cooling box 1, a protective box 402 is fixed to the right side of the liquid storage tank 401, and a No. 1 motor 403 is fixed to the right side wall of the inner cavity of the protective box 402. The output shaft of the No. 1 motor 403 passes through the right side wall of the inner cavity of the liquid storage tank 401 and extends to the inner cavity of the liquid storage tank 401 and is fixed with a rotating rod 404. The upper and lower ends of the outer surface of the rotating rod 404 are fixed with stirring blades 405. When the No. 1 motor 403 is started, The output shaft of motor No. 1 403 rotates, thereby driving the rotating rod 404. The rotation of the rotating rod 404 drives the stirring blade 405 to rotate, thereby stirring the coolant in the inner cavity of the liquid storage tank 401, so that the temperature of the coolant is quickly reduced. A refrigerator 406 is fixed to the middle of the bottom wall of the liquid storage tank 401. One end of the film is fixed to the rightmost conveyor roller 2, and then the film is rolled on the outer surface of the leftmost conveyor roller 2. Then the box cover is closed and the refrigerator 406 is started. The refrigerator 406 can reduce the temperature of the coolant.

[0025] Among them, the top of the right side of the liquid storage tank 401 is connected to a liquid inlet pipe, and the outer surface of the liquid inlet pipe is threadedly connected to a sealing cover to facilitate the staff to add coolant. The number of stirring blades 405 is four, and the four stirring blades 405 are evenly distributed at the upper and lower ends of the outer surface of the rotating rod 404.

[0026] See also Figure 4 In order to circulate the coolant, the heat exchange mechanism 3 in this embodiment includes a heat exchange tube 301 fixed to the bottom of the inner cavity of the cooling box 1, and a water pump 302 is fixed to the bottom of the left side of the cooling box 1. The left end of the heat exchange tube 301 passes through the left side wall of the inner cavity of the cooling box 1 and extends to the left side of the cooling box 1 and is connected with the water outlet end of the water pump 302. The water inlet end of the water pump 302 is connected with the water inlet pipe 303. When the water pump 302 is started, the water inlet end of the water pump 302 draws the coolant in the inner cavity of the liquid storage tank 401 into the inner cavity of the heat exchange tube 301 through the water inlet pipe 303, and the No. 2 is started. Motor 5, the output shaft of motor No. 2 5 rotates to drive the rightmost conveying roller 2 to rotate, thereby moving the film. When the film passes through the heat exchange tube 301, the heat exchange tube 301 can absorb the heat on the surface of the film, thereby reducing the temperature of the film surface. The right end of the heat exchange tube 301 is connected to the return pipe 304, and the other end of the return pipe 304 passes through the cooling box 1 and extends to the inner cavity of the liquid storage tank 401. The water in the inner cavity of the heat exchange tube 301 can flow into the inner cavity of the liquid storage tank 401 through the return pipe 304, thereby circulating the coolant in the inner cavity of the heat exchange tube 301.

[0027] The cross-section of the heat exchange tube 301 is S-shaped, and the other end of the water inlet pipe 303 passes through the left side wall of the inner cavity of the liquid storage tank 401 and extends to the inner cavity of the liquid storage tank 401 .

[0028] It should be noted that the coolant in the heat exchange tube 301 can flow back into the liquid storage tank 401 after absorbing the heat on the film surface, thereby improving the cooling effect of the film, preventing a large amount of coolant from being wasted, and reducing costs.

[0029] The working principle of the above embodiment is:

[0030] (1) When cooling the film, first fix one end of the film on the rightmost conveyor roller 2, then roll the film onto the outer surface of the leftmost conveyor roller 2, and then close the box cover and start the refrigerator 406. The refrigerator 406 can reduce the temperature of the coolant. Then start the No. 1 motor 403. The output shaft of the No. 1 motor 403 rotates, thereby driving the rotating rod 404. The rotation of the rotating rod 404 drives the stirring blade 405 to rotate, thereby stirring the coolant in the inner cavity of the liquid storage tank 401, so that the temperature of the coolant can be quickly reduced.

[0031] (2) Then start the water pump 302. The water inlet end of the water pump 302 draws the coolant from the inner cavity of the liquid storage tank 401 to the inner cavity of the heat exchange tube 301 through the water inlet pipe 303. At this time, start the No. 2 motor 5. The output shaft of the No. 2 motor 5 rotates to drive the rightmost conveyor roller 2 to rotate, thereby moving the film. When the film passes through the heat exchange tube 301, the heat exchange tube 301 can absorb the heat on the surface of the film, thereby reducing the temperature of the film surface, and the water in the inner cavity of the heat exchange tube 301 can flow into the inner cavity of the liquid storage tank 401 through the return pipe 304, thereby circulating the coolant in the inner cavity of the heat exchange tube 301.
