[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model are described clearly and completely. Apparently, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] By providing a coiling device for pet polyester film production in the embodiments of the present application, the problem that in the process of using the existing coiling device, the coiling thickness is usually not easy to adjust, and the coiling thickness of the coiling roller mainly depends on experience and observation during the coiling process, and the finally produced coiling rollers are prone to size deviation is solved. When the coiling amount of the coiling roller is too large, it increases the enterprise cost. During the quality inspection process, it is often necessary to re-coil a small number of coiling rollers, which affects the processing efficiency.

[0024] To better understand the above technical solutions, the above technical solutions will be described in detail below in conjunction with the specification drawings and specific implementation manners.

[0025] The embodiments of the present utility model disclose a coiling device for pet polyester film production. According to the attached Figures 1-4 As shown, the overall structure of the device includes a device base 1, a bracket 11, and a driving unit 12.

[0026] The device base 1 is the basic part of the entire coiling device and is used to support and fix other components.

[0027] The bracket 11 is fixed on the device base 1 and is used to support the coiling roller 2.

[0028] The driving unit 12 is also fixed on the device base 1, and its output end is clamped with the coiling roller 2 and is used to drive the coiling roller 2 to rotate, thereby coiling the polyester film.

[0029] A coiling detection mechanism is designed on the device base 1. By using the coiling detection mechanism, it is convenient to control the size of the coiling roller and ensure that the device stops working after coiling the pet polyester film to the corresponding thickness. The coiling detection mechanism consists of a carrying frame 3, an adjusting table 4, a pressure sensor 41, a movable table 5, a spring 52, etc.;

[0030] The carrier 3 is fixedly connected to the device base 1 and serves as the support structure for the coiled material detection mechanism.

[0031] The adjustment table 4 is movably clamped on the carrier 3 and is used to install and adjust the position of the pressure sensor 41.

[0032] The pressure sensor 41 is arranged on the adjustment table 4 and is used to detect the pressure change during the winding process of the polyester film to monitor the state of the coiled material.

[0033] The movable table 5 is slidably connected to the adjustment table 4 and is used to directly contact the polyester film and transfer pressure to the pressure sensor 41.

[0034] The roller 51 is fixedly connected to the movable table 5. The roller 51 reduces the friction with the polyester film to ensure accurate detection.

[0035] The spring 52 is fixedly connected between the movable table 5 and the adjustment table 4. The spring 52 is used to apply a thrust to the movable table 5 so that the movable table 5 is in a fitting state with the PET polyester film. Therefore, when the volume of the roll of the PET polyester film increases, it will drive the movable table 5 to move. Eventually, when the movable table 5 applies a target pressure to the pressure sensor 41, the device stops operating through the control system, which means that the roll reaches the target thickness.

[0036] The movable rod 53 is fixedly connected to the movable table 5. The movable rod 53 passes through the adjustment table 4 and is fixedly connected with a limit block 54. The movable rod 53 is used to limit the sliding range of the movable table 5, and the limit block 54 prevents the movable rod 53 and the movable table 5 from detaching from the adjustment table 4.

[0037] An adjustment component 6 is arranged between the carrier 3 and the adjustment table 4 of this device. The adjustment component 6 includes a nut seat 61, a fixed block 62, a fixed block 62, a lead screw 63, etc. The adjustment component 6 facilitates the adjustment of the position of the adjustment table 4, and further facilitates the control of the position of the pressure sensor 41. Therefore, it is convenient to control the thickness of the roll, making it convenient to detect and adjust the finished product thickness during the winding of the PET polyester film.

[0038] The nut seat 61 is fixedly connected to the adjustment table 4 and serves as the driving point of the lead screw 63.

[0039] A baffle 611 is arranged on the nut seat 61. The baffle 611 is used to limit the movement of the nut seat 61 along the axial direction of the lead screw 63 to ensure the accuracy of the adjustment.

[0040] The fixed block 62 is fixedly connected to the carrier 3 and provides stable support for the lead screw 63.

[0041] The lead screw 63 is rotatably connected between the fixed block 62 and the carrier 3 and is threadedly connected to the nut seat 61. By rotating the lead screw 63, the adjustment table 4 can be driven to move on the carrier 3, thereby adjusting the position of the pressure sensor 41.

[0042] A rotating handle 64 is provided on the lead screw 63, and the rotating handle 64 facilitates manual rotation of the lead screw 63 for adjustment.

[0043] The above shows and describes the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed.
