Description

Technical Field

[0001] This utility model relates to the field of PET film production technology, specifically to a finished product winding device for PET film production. Background Technology

[0002] PET film, also known as high-temperature resistant polyester film, possesses excellent physical and chemical properties, dimensional stability, transparency, and recyclability. It is widely used in magnetic recording, photosensitive materials, electronics, electrical insulation, industrial films, packaging decoration, screen protection, and optical-grade mirror surface protection. In the new energy power battery industry, PET film is required for electrical insulation protection. PET film is a comprehensive packaging film with good transparency, gloss, good airtightness and aroma retention, moderate moisture resistance (moisture permeability decreases at low temperatures), and excellent mechanical properties. Its toughness is the best among all thermoplastics, with much higher tensile strength and impact resistance than ordinary films. It also has good stiffness and dimensional stability, making it suitable for secondary processing such as printing and paper bags. After processing, PET film requires a finished product winding process. Existing winding methods include manual winding and mechanical winding. However, PET film has a certain degree of extensibility. During mechanical winding, excessive tension can easily cause significant deformation of the PET film, leading to wrinkles and misalignment when wound on the rollers. Utility Model Content

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Please see Figures 1-5 This utility model provides a technical solution: a finished product winding equipment for PET film production, including a machine box 1 and a controller 6. The top of the machine box 1 is provided with a height adjustment component 5, an auxiliary conveying component 4, and a tension monitoring component 7. The movable end of the height adjustment component 5 is fixedly installed with a winding component 3. There are two auxiliary conveying components 4 and two tension monitoring components 7. The auxiliary conveying component 4, tension monitoring component 7, and winding component 3 are arranged from left to right. The winding component 3 is used to wind the PET film 2. The two auxiliary conveying components 4 are used to assist in conveying the PET film 2 and to open the PET film 2 when two sets of tension monitoring components 7 are set up. The two tension monitoring components 7 are used to monitor the tension at two locations to improve the accuracy of tension monitoring.

[0021] The tension monitoring component 7 includes a slide rail 701, within which a lifting plate 704 is slidably mounted. A connecting shaft 702 is rotatably connected to the lifting plate 704 via bearings. A hollow roller 703 is fixedly mounted at the end of the connecting shaft 702. The PET film 2 passes under the hollow roller 703. A pressure sensor 705 is fixedly mounted on the inner wall of the slide rail 701. The lifting plate 704 presses against the sensing end of the pressure sensor 705. A counterweight component 706 is fixedly mounted on the lifting plate 704. The counterweight component 706 is used to press down on the lifting plate 704, thereby causing the hollow roller 703 to press down on the PET film 2. The tension of the PET film 2 will cause the hollow roller 703 to press down on the PET film 2. Roller 703 lifts up, which in turn lifts lifting plate 704. The force exerted by lifting plate 704 on the sensing end of pressure sensor 705 monitors the tension on PET film 2. The greater the tension on PET film 2, the lower the value detected by pressure sensor 705. Then, by reducing the winding speed of winding component 3 and the conveying speed of auxiliary conveying component 4, the tension on PET film 2 is reduced. The height of winding component 3 is adjusted up and down by height adjustment component 5 to control the V-shaped angle of PET film 2 at tension monitoring component 7 during the winding process of winding component 3, thereby reducing the influence of angle change on force change.

[0022] The take-up component 3 includes an L-shaped frame 301 and a take-up roller 303. A servo motor 302 is fixedly installed on the outer wall of the L-shaped frame 301. A rotating shaft 304 is fixedly installed at the output end of the servo motor 302. A frustum 305 is fixedly installed at the end of the rotating shaft 304. The thinner end of the frustum 305 is inserted into the take-up roller 303. The take-up roller 303 is rotatably connected to the L-shaped frame 301 through a disassembly assembly 306. The disassembly assembly 306 is used to rotatably install the take-up roller 303 on the L-shaped frame 301, so that the take-up roller 303 can be detached. The servo motor 302 drives the rotating shaft 304 to rotate, which in turn drives the frustum 305 to rotate. The force between the frustum 305 and the take-up roller 303 will drive the take-up roller 303 to rotate.

[0023] The auxiliary conveying component 4 includes a U-shaped frame 401. A servo motor 402 is fixedly installed on the outer wall of the U-shaped frame 401. A rotating shaft 403 is fixedly installed at the output end of the servo motor 402. A rotating roller 404 is fixedly installed on the outer wall of the rotating shaft 403. The PET film 2 passes over the rotating roller 404. The servo motor 402 drives the rotating shaft 403 to rotate, which in turn drives the rotating roller 404 to rotate. The force between the rotating roller 404 and the PET film 2 is used to convey the PET film 2. The counterweight component 706 includes a connecting plate 7061. The connecting plate 7061 is fixedly installed on the outer wall of the lifting plate 704. An internal threaded sleeve 7062 is fixedly installed at the bottom end of the connecting plate 7061. The internal threaded sleeve 7062 has a holding capacity. The container tube 7063 has a sealing plug 7064 inside. The outer wall of the container tube 7063 is marked with graduations. A rotating ring 8 is fixedly fitted on the outer wall of the container tube 7063. A groove 9 is opened on the top of the sealing plug 7064. By filling the container tube 7063 with liquids such as water or oil, a counterweight is achieved. The inner threaded sleeve 7062 and the container tube 7063 are connected by threads, so that the liquid in the container tube 7063 can be replaced, thereby achieving different counterweight settings. The sealing plug 7064 is set to prevent the liquid in the container tube 7063 from leaking. The rotating ring 8 is set to facilitate the rotation of the container tube 7063. The groove 9 is set to facilitate the worker to remove the sealing plug 7064 from the container tube 7063 with tweezers.

[0024] The assembly / disassembly component 306 includes a movable plate 3061, a slide groove 3062, and an electric telescopic rod 3063. The slide groove 3062 is formed on the L-shaped frame 301, and the electric telescopic rod 3063 is fixedly installed on the L-shaped frame 301. The bottom end of the movable plate 3061 is slidably disposed in the slide groove 3062. The movable plate 3061 is rotatably connected to a rotating shaft 3064 via a bearing. A frustum 3065 is fixedly installed at the end of the rotating shaft 3064. The frustum 3065 is pushed into the take-up roller 303. The position of the movable plate 3061 is adjusted by the electric telescopic rod 3063, so that the rotating shaft 3064 moves and pushes the frustum 3065 onto the take-up roller 303. Because the rotating shaft 3064 is rotatably connected to the movable plate 3061, the rotation of the take-up roller 303 can drive the frustum 3065 to rotate synchronously.

[0025] The height adjustment component 5 includes a mounting groove 501, which is formed on the housing 1. An electric telescopic rod 502 is fixedly installed on the inner wall of the mounting groove 501. The telescopic end of the electric telescopic rod 502 is fixedly connected to the bottom of the L-shaped frame 301. The height of the take-up roller 303 is adjusted by moving the L-shaped frame 301 up and down through the electric telescopic rod 502.

[0026] Working principle: In use, the PET film 2 is wound onto the take-up roller 303 after passing through the left rotating roller 404, the left hollow roller 703, the right rotating roller 404, and the right hollow roller 703 in sequence. During the winding process, if the force exerted by the PET film 2 on the hollow roller 703 changes, the force exerted on the sensing end of the pressure sensor 705 will also change. If the detected force is small, the tension on the PET film 2 is too large. At this time, the controller 6 controls the servo motor 1 302 and the servo motor 2 402 to reduce the speed of the take-up roller 303 and the rotating roller 404, thereby reducing the tension on the PET film 2.

[0027] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
