[0002] Polyester film is a transparent or translucent polymer material made of polyester resin. It has excellent physical properties and chemical stability, and has the characteristics of high tensile strength and rigidity, heat resistance, corrosion resistance and good electrical insulation properties.

[0003] At present, most of the existing polyester film cutting devices are fixed structures and can only cut films of fixed width, which has certain limitations. In addition, polyester films of different widths are difficult to limit when cutting. In this regard, we propose a cutting device that can be used for polyester films of different widths to solve the above problems. Utility Model Content

[0007] Furthermore, a motor is fixedly connected to an outer wall of one side of the mechanical frame, and an output end of the motor is fixedly connected to one end of the first material receiving reel.

[0008] Furthermore, a first material receiving reel and a second material receiving reel are rotatably connected between the inner walls on both sides of the mechanical frame, a belt is transmission-connected at one end between the first material receiving reel and the second material receiving reel, and the polyester film is wound around the first material receiving reel and the second material receiving reel.

[0009] Furthermore, a feeding shaft is rotatably connected between the inner walls on both sides of the mechanical frame, and the polyester film is wound around the feeding shaft.

[0010] Furthermore, a transition shaft is rotatably connected between the inner walls on both sides of the mechanical frame, and the polyester film is wrapped around the transition shaft.

[0012] Furthermore, one end of the screw rod is fixedly connected with an adjusting knob.

[0013] The beneficial effects of the utility model are:

[0014] 1. By twisting the screw rod, the slider moves on the limit rail, thereby driving the cutter to move, and then adjusting the cutting position of the polyester film so that the polyester film can be cut into different widths.

[0015] 2. By pulling the limiting ring to move on the film pressing shaft, the limiting ring is brought into contact with the polyester film, thereby limiting the transmission of the polyester film, thereby preventing the film from deviating during transmission.

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Reference Figure 1-Figure 4 A cutting device suitable for polyester films of different widths comprises a mechanical frame 1 and a polyester film 17. A cutting table 9 is fixed between the inner walls of both sides of the mechanical frame 1 by bolts. A lead screw 10 is rotatably inserted between the inner walls of both sides of the mechanical frame 1 by bearings. A slider 11 is threadedly sleeved on the outer wall of the lead screw 10. A cutter 12 is fixed to the bottom of the slider 11 by bolts. The polyester film 17 is cut by the cutter 12. A limit rail 14 is fixed between the inner walls of both sides of the mechanical frame 1 by bolts. The slider 11 slides on the limit rail 14. The lead screw 10 is turned to drive the slider 11 to move on the limit rail 14, thereby driving the cutter 12 to move, thereby adjusting the cutting position of the polyester film 17.

[0024] A motor 2 is fixed to an outer wall of one side of the mechanical frame 1 by bolts, and an output end of the motor 2 is fixedly connected to one end of the first material receiving reel 3. A first material receiving reel 3 and a second material receiving reel 4 are rotatably plugged in between the inner walls of both sides of the mechanical frame 1 through bearings, and a belt 5 is transmission-connected to one end between the first material receiving reel 3 and the second material receiving reel 4. A polyester film 17 is wound around the first material receiving reel 3 and the second material receiving reel 4. The first material receiving reel 3 and the second material receiving reel 4 are driven by the motor 2 and the transmission action of the belt 5 to rotate, thereby winding the film. A feed shaft 6 is rotatably plugged in between the inner walls of both sides of the mechanical frame 1 through bearings, and the polyester film 17 is wound around the feed shaft 6. A transition shaft 7 is rotatably inserted between the inner walls on both sides of the mechanical frame 1 through bearings, and the polyester film 17 is wound around the transition shaft 7. A film pressing shaft 8 is rotatably inserted between the inner walls on both sides of the mechanical frame 1 through bearings, and the polyester film 17 is wound around the film pressing shaft 8. Two limit rings 15 are slidingly sleeved on the outer wall of the film pressing shaft 8. The limit ring 15 is pulled to move on the film pressing shaft 8, so that the limit ring 15 contacts with the polyester film 17, and then the transmission of the polyester film 17 is limited. Two permanent magnets 16 are embedded in the inner wall of the limit ring 15, and the permanent magnets 16 are attracted to the film pressing shaft 8, so as to fix the limit ring 15. An adjusting knob 13 is welded at one end of the screw rod 10, so as to facilitate the operation of the screw rod 10.

[0025] The working principle of this embodiment is as follows: when in use, one end of the polyester film 17 is passed around from the bottom of the transition shaft 7, and then, one end of the polyester film 17 is passed around from the top of the film pressing shaft 8, and then the limiting ring 15 is pulled to move on the film pressing shaft 8, so that the limiting ring 15 contacts with the polyester film 17, thereby limiting the transmission of the polyester film 17, and then, one end of the polyester film 17 is respectively wound around the first material receiving reel 3 and the second material receiving reel 4, and then, driven by the motor 2 and the transmission action of the belt 5, the first material receiving reel 3 and the second material receiving reel 4 are driven to rotate, thereby winding the film, and then, turning the adjusting knob 13 drives the lower screw rod 10 to rotate, thereby driving the slider 11 to move on the limiting rail 14, and then driving the cutter 12 to move, thereby adjusting the cutting position of the polyester film 17, and during the transmission process of the polyester film 17, the cutter 12 is used to cut the polyester film 17.

[0026] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
