[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Example 1, please refer to Figures 1-3 The present invention provides a technical solution: a multi-stage cooling device in a plastic film processing equipment, comprising a housing 1, a base plate 101 fixedly connected to the bottom of the housing 1, four fan holes 102 opened on the top of the housing 1, fan brackets 103 fixedly connected to the inner walls of the fan holes 102, and a fan 104 rotatably connected to one end of the fan brackets 103 via a bearing. This arrangement is intended to allow for simple air cooling of the film after it passes through the first-stage cooling mechanism 2, via the fan 104. The device also includes:

[0028] The first-stage cooling mechanism 2 includes a roller support 201 fixedly connected to the top of the base plate 101, and a gear support 202 fixedly connected to the top of the base plate 101. This arrangement is intended to provide a place for the upper roller 204 and the lower roller 203. The end of the roller support 201 away from the outer shell 1 is rotatably connected to the lower roller 203 through a bearing, and the end of the roller support 201 away from the outer shell 1 is rotatably connected to the upper roller 204 through a bearing. Both rollers are hollow, which allows coolant to enter the rollers through the circulating water pipe 603 and then flow out through the circulating water pipe 603. This design can cool the two rollers, so that both sides of the film can be well cooled when the film passes through the shaft.

[0029] The power mechanism 3 includes a motor 301 fixed on the top of the base plate 101, and a gear 302 is fixedly connected to the output end of the motor 301.

[0030] The output end of the motor 301 passes through the gear bracket 202. The purpose of this arrangement is to drive the rotation of the shaft and the conveyor belt 403 of the entire equipment through the motor 301.

[0031] The secondary cooling mechanism 4 includes four roller supports 401 fixedly connected to the top of the base plate 101. A roller 402 is rotatably connected between two roller supports 401 via bearings. A conveyor belt 403 is rotatably connected to the outer wall of the roller 402. An air-cooling component 5 is fixedly connected to the inner wall of the outer shell 1. A cooling component 6 is fixedly connected to the top of the base plate 101. The purpose of this arrangement is to provide sufficient coolant to the primary cooling mechanism 2 and to provide cooled air to the secondary cooling mechanism 4.

[0032] The end of the gear bracket 202 away from the roller bracket 201 is rotatably connected to the lower gear 303 via a bearing, and the end of the gear bracket 202 away from the roller bracket 201 is rotatably connected to the upper gear 305 via a bearing.

[0033] In this configuration, the lower gear 303 is fully meshed with the first gear 302, and the upper gear 305 is fully meshed with the lower gear 303. The lower gear 303 is fixedly connected to the lower roller shaft 203 via a bearing, and the upper gear 305 is fixedly connected to the upper roller shaft 204 via a bearing. This arrangement allows the upper roller shaft 204 and the lower roller shaft 203 to rotate together with the movement of the motor 301. At the same time, the two roller shafts rotate at the same speed but in opposite directions, allowing the film to pass through the first-stage cooling mechanism 2 more effectively. Furthermore, because the shaft is constantly rotating, the heat absorption surface of the shaft is constantly changing, resulting in better heat dissipation.

[0034] The lower gear 303 is fixedly connected to a roller 304 at one end away from the gear bracket 202. A belt 306 is rotatably connected to the inner wall of the roller 304. One of the roller brackets 401 is rotatably connected to a roller 307 at one end away from the roller 402 via a bearing.

[0035] Among them, roller 304 is rotatably connected to roller 307 via belt 306, and roller 307 is fixedly connected to one of the roller shafts 402 via bearing. This arrangement allows the conveyor belt 403 to run normally and allows the film to enter the secondary cooling mechanism 4.

[0036] Example 2 differs from Example 1 in that: Please refer to... Figures 1-7 As shown, the air-cooled assembly 5 includes two air guide chambers 501 fixedly connected to the inner wall of the outer casing 1. The lower end of the air guide chamber 501 is provided with an air inlet 502, and the upper end of the air guide chamber 501 is provided with an air outlet 503. The inner wall of the air guide chamber 501 is rotatably connected to a turbo fan 504 through a bearing. The top of the two air guide chambers 501 is fixedly connected with an air pipe 505. The purpose of this arrangement is to draw the air cooled by the condenser 602 into the air guide chamber 501 through the air inlet 502. Part of the gas is blown out from the air outlet 503 to cool the lower end of the film, and the other part of the gas enters the air pipe 505 and cools the upper part of the film through the air outlet assembly 51.

[0037] A baffle 506 is fixedly connected to the end of the air guide chamber 501 away from the outer shell 1. An elastic component 507 is fixedly connected to the outer wall of the air pipe 505. A pressure plate 508 is fixedly connected to the end of the elastic component 507 away from the air pipe 505. The purpose of this arrangement is to prevent the film from being blown up when air is blown from the air outlet 503, thereby affecting the normal process. An air outlet component 51 is fixedly connected to the lower end of the air pipe 505. This arrangement is for cooling the upper part of the film.

[0038] The air outlet assembly 51 includes a cold air nozzle 511 fixedly connected to the lower end of the air pipe 505. The outer wall of the cold air nozzle 511 has an air outlet hole 512 and a guide plate 513 fixedly connected to the outer wall of the cold air nozzle 511. This arrangement ensures that after the air reaches the cold air nozzle 511, it will not be blown directly onto the membrane. Instead, part of the air will be blown onto the membrane through the lower air outlet hole 512, and part of the air will be blown onto the guide plate 513 through the upper air outlet hole 512. Then, the guide plate 513 will blow onto the membrane, thereby increasing the area covered by the cold air and improving the cooling effect.

[0039] The cooling assembly 6 includes a cooling box 601 fixedly connected to the top of the base plate 101, with several condenser pipes 602 fixedly connected to the inner wall. The purpose of this arrangement is to cool the conveyor belt 403, and at the same time, to allow the air-cooling assembly 5 to draw in cold air. The left and right ends of the cooling box 601 are respectively fixedly connected to circulating water pipes 603. The purpose of this arrangement is to provide cooling liquid to the upper roller shaft 204 and the lower roller shaft 203.

[0040] One specific application of this embodiment is:

[0041] When the equipment starts working, motor 301 will start working and drive upper gear 305 and lower gear 303 to rotate together through gear 302. The rotation of the two gears will also drive the upper roller 204 and lower roller 203 to rotate. When the film enters the first-stage cooling mechanism 2, the two rollers will transport the film into the equipment. At the same time, the coolant inside the rollers will cool the rollers. After being cooled, the rollers will absorb the heat from the surface of the film, thus performing the first cooling treatment on the film.

[0042] When the equipment starts working, the lower gear 303 drives the roller 402 to rotate via the belt 306, roller 304, and roller 307, thereby starting the conveyor belt 403. When the film enters the secondary cooling mechanism 4, the film will fall onto the conveyor belt 403. The fan 104 on the outer casing 1 will perform a second cooling process on the film. As the conveyor belt 403 moves, when the film reaches the air-cooling mechanism, the film will be lifted by the small ramp outside the air-cooling room. At the same time, air is blown on both the upper and lower sides of the film to cool it down. Meanwhile, the baffle 506 and the pressure plate 508 prevent the film from being blown up.
