[0003] In the prior art, such as announcement number CN219009453U, a flattening machine for preparing plastic film is disclosed. After the plastic film enters from the inlet, it is wrapped along the outer side of the inner drum and then discharged from the outlet. At this time, the outlet above the heat insulation board discharges hot air to soften the plastic film. Then, the wrinkles are flattened by the extrusion of the heat-conducting roller. Then, cold air is discharged from the outlet below the heat insulation board to cool the film, eliminate wrinkles, and improve the quality of the film. In this process, the driving motor drives the inner drum to rotate and tension the film, so that the film flattening effect is better. The technical solution of the above patent has the following shortcomings: 1. The lack of a plastic film limit assembly easily causes wrinkles in the plastic film when flattening; 2.

One end of the spring 9 away from the inner wall of the circular groove 8 is fixedly connected with a fixing rod 10, and one end of the two fixing rods 10 away from the spring 9 is fixedly connected with a limiting roller 11. The two limiting rollers 11 are in contact with each other, and the plastic film is passed through the guide port 3 and then comes into contact with the two limiting rollers 11. At this time, the limiting rollers 11 are forced to drive the fixing rod 10 to compress the spring 9 in the circular groove 8, so that the spring 9 cooperates with the fixing rod 10 to drive the two limiting rollers 11 to always come into contact with the plastic film passing through the guide port 3, thereby effectively limiting the plastic film and avoiding wrinkles when the plastic film is flattened.
[0024] Three first support seats 4 and two second support seats 5 are fixedly installed on the bottom of the box body 1 near the front side. The three first support seats 4 and the rear inner wall of the box body 1 are all horizontally rotated and penetrated with first guide rollers 6. The two first support seats 4 and the rear inner wall of the box body 1 are all horizontally rotated and penetrated with second guide rollers 7. The three first support seats 4 are evenly spaced, and the two second support seats 5 are located between two adjacent first support seats 4. The three first guide rollers 6 and the two second guide rollers 7 are all driven by a motor, and the motor (not shown in the figure) is used to drive the first guide rollers 6 to rotate horizontally. The three first guide rollers 6 and the two second guide rollers 7 are arranged in a roundabout manner, and the plastic film is sequentially passed around the three first guide rollers 6 and the two second guide rollers 7 arranged in a roundabout manner, and the plastic film is passed through the material guide port 3 on the right side, and a motor (not shown in the figure) is started to drive the three first guide rollers 6 and the two second guide rollers 7 to rotate, so that the plastic film is transported in the box body 1. At this time, the three first guide rollers 6 and the two second guide rollers 7 arranged in a roundabout manner driven by the motor effectively tension the plastic film to improve the flattening effect.
[0025] A heat-conducting assembly is mounted on the bottom of the box body 1. The heat-conducting assembly is located below the two second guide rollers 7. The heat-conducting assembly includes a circulating heat-conducting pipe 12 fixedly penetrating the inner walls on the left and right sides of the box body 1. The circulating heat-conducting pipe 12 guides hot water into a heat-conducting tube 13 of aluminum-copper alloy in cooperation with a circulating pump (not shown in the figure), so that the heat-conducting tube 13 heats and flattens the plastic film that passes around the second guide roller 7, and the blower 15 cooperates with the three-way pipe fitting 17, the air guide pipe 18, the wind cover 19 and the vent 16 to quickly blow air and cool down the plastic film that passes around the first guide roller 6, thereby improving the thin film In order to achieve a cooling effect after the film is heated, one end of the two circulating heat-conducting pipes 12 close to the bottom of the box body 1 is connected to a heat-conducting tube 13, and the same liquid-conducting tube 14 is connected between the two heat-conducting tubes 13. The two heat-conducting tubes 13 are respectively located directly below the two second guide rollers 7, and the heat-conducting tubes 13 and the second guide rollers 7 are arranged in parallel and of equal length. The material of the heat-conducting tube 13 is an aluminum-copper alloy. The aluminum-copper alloy heat-conducting tube 13 can conduct heat to the plastic film that passes by the second guide roller 7, so that the plastic film stretched between the first guide roller 6 and the second guide roller 7 can be better flattened.
[0026] A blast cooling mechanism is vertically penetrated on the top surface of the box body 1, and the blast cooling mechanism includes a blower 15 fixedly installed on the upper end of the box body 1 and a vent 16 arranged on the right inner wall of the box body 1 near the bottom.

[0027] When the utility model is in use, the sealing door 2 on the box body 1 is opened, and the plastic film is passed through the material guide port 3 on the left side of the box body 1, so that the plastic film is in contact with the two limiting rollers 11. At this time, the spring 9 in the circular groove 8 cooperates with the fixing rod 10 to drive the two limiting rollers 11 to always be in contact with the plastic film passing through the material guide port 3, effectively limiting the plastic film to avoid wrinkles when the plastic film is flattened. The plastic film is sequentially passed around the three first guide rollers 6 and the two second guide rollers 7 that are arranged in a circuitous manner, and the plastic film is passed through the material guide port 3 on the right side. The motor (not shown in the figure) is started to drive the three first guide rollers 6 and the two second guide rollers 7. The second guide roller 7 rotates to transport the plastic film in the box body 1.
