[0041] Please refer to Figures 1-4 The embodiments provided by the utility model have the advantages of simple structure, convenient use, high efficiency, low cost, etc.

[0042] The utility model provides a kind of heat setting processing device for polyester film, including heat treatment box 1, the inside one side of heat treatment box 1 is equipped with the heating box 3 for heating to polyester film, and heating box 3 is used to heat treatment to polyester film, to facilitate subsequent tensile deformation, and produce thinner polyester film.

[0043] The inside other side of heat treatment box 1 is equipped with the guide component for guiding polyester film discharge and the tension adjusting component for adjusting polyester film tension, wherein, guide component includes straightening roller 10, feed roller 8, second guide roller 9, first guide roller 5 and discharge roller 4, straightening roller 10 is respectively mounted on the inside side wall of heat treatment box 1 at the discharge port 31 and feed port side of heating box 3, feed roller 8 and discharge roller 4 are parallel to straightening roller 10 and are mounted on the inside side wall of heat treatment box 1, first guide roller 5 and second guide roller 9 are equipped with two respectively, one of two first guide roller 5 and second guide roller 9 is located directly below discharge roller 4 and feed roller 8 respectively, and first guide roller 5 and second guide roller 9 are respectively mounted on the inside side wall of heat treatment box 1, the end of straightening roller 10, feed roller 8, second guide roller 9, first guide roller 5 and discharge roller 4 are rotatably installed on the inside side wall of heat treatment box 1 by bearing seat.

[0044] The discharge direction of heated polyester film is guided to change by guide component, so as to provide the condition for tension adjusting component to provide tensile polyester film, and the principle is as follows: thicker polyester film is heated after passing through the above of straightening roller 10 after heating box 3, so that polyester film is heated in parallel in heating box 3, and the polyester film that passes out from the discharge port 31 of heating box 3 passes through the above of straightening roller 10, and then is wound on tension adjusting component after passing through the above of feed roller 8, and then is wound on two second guide rollers 9 respectively, and then is wound on two first guide rollers 5 respectively after passing through tension detection component 2, and then is wound on tension adjusting component again, and finally passes through discharge roller 4.

[0045] In this process, heated polyester film is stretched into thinner polyester film under the cooperation of guide component and tension adjusting component.

[0046] Tension adjusting component includes tension adjusting roller 6 and chute 7, and the two tension adjusting rollers 6 and chutes 7 are symmetrically arranged on the inside side wall of heat treatment box 1 with tension detection component 2 as the axis, and the shaft rods on the ends of the two tension adjusting rollers 6 are slidably connected in the two chutes 7, the two chutes 7 are arc-shaped grooves, and the shaft rods on the ends of the two tension adjusting rollers 6 are rotatably connected to the driving components 13 through bearing seats.

[0047] Because the slide groove 7 is an arc-shaped groove structure, when the tension adjusting roller 6 slides in the slide groove 7, the tension adjusting roller 6 will change position along the arc direction of the slide groove 7, while the installation positions of the flattening roller 10, the feeding roller 8, the second guide roller 9, the first guide roller 5 and the discharging roller 4 are fixed, and if the tension adjusting roller 6 slides along the slide groove 7, the polyester film in the slide groove 7 will be stretched, and thinner polyester film can be obtained.

[0048] The tension adjusting assembly is swung on the side wall of the heat treatment box 1 through the driving assembly 13 installed on the back of the heat treatment box 1, the driving assembly 13 includes a rocker arm 131, a fixed shaft 132, two driven gears 133, a driving gear 134, a servo motor 135 and a mounting bracket 136, one end of the rocker arm 131 is fixedly installed with the shaft rod end of the tension adjusting roller 6 through a bearing seat respectively, the other end of the rocker arm 131 is internally keyed connected with the side wall of the fixed shaft 132, the fixed shaft 132 is installed on the back of the heat treatment box 1 through a bearing seat, the two driven gears 133 are provided, the two driven gears 133 are keyed connected with the side wall of the fixed shaft 132 respectively, and the side walls of the two driven gears 133 are meshingly connected with each other, the side wall of one of the driven gears 133 is also meshingly connected with the side wall of the driving gear 134, the inside of the driving gear 134 is keyed connected with the output shaft of the servo motor 135, the servo motor 135 is fixedly installed on the side wall of the mounting bracket 136 through screws, and the mounting bracket 136 is fixedly installed on the back of the heat treatment box 1 through screws.

[0049] The principle is that the output shaft of the servo motor 135 can be reversed through the work of the servo motor 135, and then the driving gear 134 can be rotated with the output shaft of the servo motor 135, so that one of the driven gears 133 can be rotated, and the two driven gears 133 are in meshing relationship, so that the two driven gears 133 are rotated in opposite angle directions under the driving of the driving gear 134, which drives the two rocker arms 131 to swing with the fixed shaft 132 as the center, so that the tension adjusting rollers 6 on the ends of the two rocker arms 131 slide in the slide grooves 7 respectively, so as to change the tension of the polyester film, and thinner polyester film can be obtained.

[0050] The inner bottom surface of the heat treatment box 1 is provided with a tension detection assembly 2 for detecting the tension, which comprises two tension sensors 21 and a detection roller 22. The two ends of the detection roller 22 are fixedly installed on the detection tables of the tension sensors 21 through bearing seats. The two tension sensors 21 are fixedly installed on the inner bottom surface of the heat treatment box 1 through screws. Since the polyester film passes below the detection roller 22 and the polyester films on both sides are wound on the second guide roller 9 and the first guide roller 5, if the tension adjusting assembly changes the tension of the polyester film, the detection roller 22 will be affected by the change of the acting force, so that the tension of the polyester film can be detected by the tension sensor 21, thereby preventing the polyester film from being broken or excessively deformed due to excessive tension.

[0051] The inner side wall of the heat treatment box 1 between the discharge port 31 of the heating box 3 and the guide assembly is provided with a temperature detection assembly for detecting the temperature of the polyester film.

The surface temperature of the polyester film discharged from the discharge port 31 of the heating box 3 is detected by the temperature sensor 12, so as to ensure that the heating temperature of the polyester film meets the required temperature for stretching, thereby preventing the polyester film from being broken due to excessive stretching of the polyester film by the tension adjusting assembly caused by too low temperature of the polyester film.

[0052] The above only describes the preferred embodiments of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various modifications and changes.
