[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-3 This embodiment provides a calendering device for manufacturing photovoltaic EVA encapsulation film, including a housing 1 and a conveying roller 2 disposed inside the housing. The housing 1 is provided with a pressure roller assembly and a cleaning assembly. The pressure roller assembly includes a first electric push rod 3 disposed on the top of the housing 1, a mounting frame 5 fixedly connected to the output end of the first electric push rod 3, and a pressure roller 6 movably mounted between the two side walls of the mounting frame 5. The pressure roller 6 is located directly above the conveying roller 2. The cleaning assembly includes a pair of second electric push rods 4 disposed on the top of the housing 1 and respectively located on both sides of the first electric push rod 3. A cleaning seat 9 connected to a water supply device is fixedly installed below the second electric push rod 4. Brushes 10 are respectively installed on opposite sides of the two cleaning seats 9.

[0018] The two cleaning seats 9 are hollow structures and are connected to the water supply device through pipes. Several nozzles 901 are arranged on their opposite sides. The drainage assembly includes a collection box 11 located at the bottom of the outer shell 1. The collection box 11 is fixedly connected to a drain pipe 13. A control valve 14 is arranged on the drain pipe 13. A filter screen 12 is also arranged on the collection box 11. A water pump 7 connected to the water supply device is arranged on the outside of the outer shell 1. The two cleaning seats 9 are connected to the water pump 7 through a Y-shaped pipe 8. A rotating hole is opened inside the outer shell 1. The conveying roller 2 is rotatably connected to the outer shell 1 through the rotating hole. An installation hole is opened on the top of the outer shell 1. The first electric push rod 3 is fixedly connected to the outer shell 1 through the installation hole.

[0019] The second electric push rod 4 is energized and extends, causing the cleaning seat 9 in the cleaning assembly to move up and down. The water pump 7 draws out the cleaning water from inside the water supply assembly and delivers it to the inside of the cleaning seat 9 through the Y-shaped pipe. The cleaning water inside the cleaning seat 9 is sprayed out through the nozzle 901 to spray the brush 10. When the cleaning assembly moves up and down, the brush 10, which is covered with cleaning liquid, contacts the surface of the pressure roller 6 and the conveying roller 2 to brush them and clean the surface residue. In practical applications, the brush 10 can be designed as two layers as shown in the figure, but is not limited to two layers. This allows for thorough and comprehensive contact brushing of the pressure roller 6 and the conveying roller 2.

[0020] Two through holes are provided on the right side of the outer casing 1. The Y-shaped tube 8 extends into the interior of the outer casing 1 through the through holes. The cleaning seat 9 is located inside the outer casing 1. The two cleaning seats 9 are located on the front and back of the mounting bracket 5, respectively. Insert blocks are fixedly connected to both sides of the collection box 11. The collection box 11 is inserted into the outer casing 1 through the insert blocks. A drain hole 15 is provided on the front of the collection box 11. The drain pipe 13 is connected to the collection box 11 through the drain hole 15.

[0021] The wastewater generated during cleaning falls into the collection box 11 due to gravity. The filter screen 12 inside the collection box 11 filters and separates the residues and impurities in the wastewater, making it easier to process the residues and wastewater after cleaning.

[0022] When the control valve 14 is opened, the wastewater inside the collection box 11, filtered by the filter screen 12, is discharged through the drain pipe 13, which facilitates the transportation of wastewater and reduces the weight of the collection box 11, allowing users to pull out the collection box 11 for cleaning.

[0023] When the impurities and residues adsorbed on the conveyor rollers and pressing rollers inside the calendering equipment are brushed, the control valve 14 is opened, and the wastewater filtered by the filter screen 12 inside the collection box 11 is discharged through the drain pipe 13, reducing the weight of the collection box 11.

[0024] The working principle of the above embodiments is as follows: The water pump 7 draws out the cleaning water from inside the water supply assembly and delivers it to the inside of the cleaning seat 9 through the Y-shaped pipe. The water is then discharged through the nozzle 901 to spray the brush 10. At the same time, the second electric push rod 4 is energized and extends and retracts, causing the cleaning seat 9 to move up and down. The brush 10 contacts the pressure roller 6 and the conveying roller 2 to brush away the residues and impurities on the outside of the pressure roller 6 and the conveying roller 2.
