Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0026] like Figures 1 to 7 A flattening device for film processing is shown, comprising a first flattening roller A, a tensioning roller 1 and a second flattening roller B arranged in order from high to low; the first flattening roller A and the second flattening roller B have the same structure, both comprising a rotating shaft 2 and a roller body 3 arranged on the outer ring of the rotating shaft;

[0027] The roller body 3 includes a connecting roller body 301 and a fixed roller body 302. The connecting roller bodies 301 are two and are respectively located at the two ends of the fixed roller body 302. The diameter of the connecting roller body 301 is smaller than that of the fixed roller body 302. The two connecting roller bodies 301 are respectively detachably provided with a left flattening portion 4 and a right flattening portion 5.

[0028] A left boss 401 is provided on the circumference of the left flattened portion 4, and the left boss 401 is tilted; a right boss 501 is provided on the circumference of the right flattened portion 5, and the right boss 501 is tilted, and the left boss 401 and the right boss 501 are tilted in opposite directions;

[0029] The outer surfaces of the left boss 401 and the right boss 501 are both flush with the outer surface of the fixed roller body 302 .

[0030] When the flattening device of the utility model is in use, the film passes through the first flattening roller A, the tensioning roller 1 and the second flattening roller B in sequence, and the first flattening roller A and the second flattening roller B are used to flatten the film. The setting of the tensioning roller 1 applies a certain tension to the film to ensure that the film maintains a certain tension during the flattening process, thereby avoiding relaxation or wrinkles in the film and ensuring the flattening effect of the first flattening roller A and the second flattening roller B on the film. The first flattening roller A and the second flattening roller B have the same structure. Since the two connecting roller bodies 301 at both ends of the roller body 3 are respectively provided with a left flattening part 4 and a right flattening part 5, when the driving shaft 2 drives the roller body 3 to rotate, the left flattening part 4 and the right flattening part 5 rotate synchronously with the fixed roller body 302. Since the left boss 401 on the left flattening part 4 and the right boss 501 on the right flattening part 5 are inclined in opposite directions, when the fixed roller body 302 rotates, the left boss 401 and the right boss 501 rotate synchronously, and the two side edges of the film are pushed toward the two side edges of the film through the left boss 401 and the right boss 501, so as to flatten the wrinkles or adhesions on the two side edges of the film, ensure that the two side edges of the film are in a flat state, ensure that the two side edges are flush when the film is subsequently rolled up, and ensure the quality of the film. As a preferred embodiment, the left boss 401 and the right boss 501 in the present application are both made of rubber or silicone material. The rubber or silicone material can provide a soft surface to reduce the friction on the film, thereby preventing the film from being damaged during the flattening process.

[0031] The left flattening part 4 and the right flattening part 5 in the present application can be detachably arranged on the connecting roller body 301, and the left flattening part 4 and the right flattening part 5 of different models or sizes can be selected according to the width or thickness of the film to meet the needs of flattening various films. Specifically, the left flattening part 4 and the right flattening part 5 in the present application are both hollow circular structures; and the grooves 6 are respectively provided between the adjacent left bosses 401 and the adjacent right bosses 501, and the first connecting holes 7 are provided in the grooves 6; the second connecting holes 8 are provided on the two connecting roller bodies 301, and the first connecting holes 7 and the second connecting holes 8 are connected by screws 9. When it is necessary to replace the wider or narrower left flattening part 4 and right flattening part 5 according to the width of the film, since the left flattening part 4 and the right flattening part 5 in the present application are connected to the connecting roller body 301 by screws 9, it is only necessary to remove the screws 9, release the connection relationship between the left flattening part 4 and the right flattening part 5 and the connecting roller body 301, and then remove the left flattening part 4 and the right flattening part 5 from the connecting roller body 301 respectively, and then put the longer left flattening part 4 and the right flattening part 5 on the corresponding connecting roller body 301 respectively, and realize the connection between the left flattening part 4 and the right flattening part 5 and the connecting roller body 301 by screws, so as to adapt to the flattening of films of different widths and improve the adaptability of the flattening device to films of different widths. The left boss 401 on the left flattening part 4 and the right boss 501 on the right flattening part 5 in the present application can be set to different widths according to needs to meet the needs of various films.

[0032] As a preferred embodiment, guide rails 10 are provided on the outer surfaces of the two connecting roller bodies 301 in the present application, and guide grooves 11 matching the guide rails are provided on the inner walls of the left flattening part 4 and the right flattening part 5. When the left flattening part 4 and the right flattening part 5 are respectively sleeved on the two connecting roller bodies 301, the guide grooves 11 on the left flattening part 4 and the right flattening part 5 are matched and sleeved in the guide rails 11 on the corresponding connecting roller body 301. The setting of the guide rails 11 and the guide grooves 11 plays a guiding role in the installation of the left flattening part 4 and the right flattening part 5, which is conducive to improving the assembly efficiency of the left flattening part 4 and the right flattening part 5 with the connecting roller body 301, and ensuring the subsequent flattening efficiency of the film.

[0033] As a preferred embodiment, the two sides of the roller body 3 in the present application are respectively provided with a suction pipe 12, and the suction pipe 12 is connected to a suction fan. In the process of flattening the film, the suction fan is started, and the suction fan adsorbs the two side edges of the film through the suction pipe 12, and cooperates with the left boss 401 on the left flattening part 4 and the right boss 501 on the right flattening part 5 to push the two side edges of the film, which greatly improves the efficiency of flattening the film. More specifically, the suction pipe 12 in the present application is a telescopic hose. When the left flattening part 4 and the right flattening part 5 are replaced according to the width of the film, the telescopic hose can adjust the position of the suction pipe 12 according to the width of the film, so as to ensure the suction effect of the suction pipe 12 on the two side edges of the film, thereby ensuring the adsorption and flattening effect of the film.

[0034] The tensioning roller 1 in the present application is provided with a lifting part 13 at both ends, and the bottom end of the lifting part 13 is provided with a slide groove 15 arranged in the support platform through a slider 14. The tensioning roller 1 is moved up and down by the lifting part 13, and the tensioning roller 1 is moved left and right by the movement of the slider 14 along the slide groove 15, thereby realizing the up and down and left and right adjustment of the position of the tensioning roller 1, so as to adapt to the tensioning of different types of films, and at the same time maintain the tensioning pressure on different types of films, so as to ensure that the film maintains a certain tension during the flattening process, so as to prevent the film from wrinkling or deformation.
