Description

Technical Field

[0001] This utility model relates to the field of PET protective film leveling technology, specifically a PET protective film leveling device. Background Technology

[0002] PET protective film, also known as thin film, is characterized by its good transparency, light weight, and high strength. It is mainly used in electronic products such as mobile phones and computers.

[0003] China has disclosed a PET film leveling device, with the announcement number CN222820927U. The device uses a pushing component to move the bottom PET protective film on the carrier plate to the leveling mechanism, which then levels the PET protective film and transports it to the conveyor belt for output. This eliminates the need for manual loading and unloading of PET protective films one by one, thereby improving the problem of manual loading and unloading during the leveling and wrinkle removal of PET protective films and reducing labor costs.

[0004] Based on the above-disclosed solutions and existing technologies, the existing PET protective film leveling device cannot repeatedly level the PET protective film, resulting in poor leveling effect and low reliability. Furthermore, when the PET protective film is wound up, the tension may cause the edges to curl up. Therefore, we propose a PET protective film leveling device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a PET protective film leveling device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a PET protective film leveling device, comprising a work box, an unwinding roller connected inside the work box, two pressure rollers connected to the inner wall of the work box, an mounting plate installed at one end of the top of the work box, a rotating rod rotatably connected to the surface of the mounting plate, a rotating rod fixedly connected to the bottom of the rotating rod, a sliding rod connected to one end of the rotating rod, a sliding ring slidably connected to one end of the sliding rod, and a horizontal plate connected to both ends of the sliding ring via connecting rods. A T-shaped rod is fixedly connected to one side of the horizontal plate, a C-shaped frame is connected to the bottom of the T-shaped rod, and a smoothing roller is connected inside the C-shaped frame.

[0007] The working box has a take-up roller connected to one end. Anti-tilting plates are provided on both sides of the surface of the take-up roller. A telescopic rod is fixedly connected to the top of the anti-tilting plate. A connecting plate is fixedly connected to one end of the telescopic rod. Rotating rods A are rotatably connected to both sides of the connecting plate. Rotating rod B is rotatably connected to one end of the connecting plate. A moving plate is rotatably connected to one end of the rotating rod B. Rotating rod C is rotatably connected to one end of the moving plate. Rotating rod D is rotatably connected to one end of the rotating rod C. A support rod is connected to one end of the rotating rod. A turntable is connected to one end of the intermediate shaft of the turntable via a synchronous belt drive. One end of the bevel gear set is connected to the rotating rod.

[0008] Optionally, the inner wall of the work box is provided with a sliding groove for one end of the T-shaped rod to slide.

[0009] Optionally, one end of the rotating rod A is rotatably connected to a rotating groove opened on the surface of the mounting plate.

[0010] Optionally, the bevel gear set consists of two bevel gears, one of which is connected to the rotating rod, and the other bevel gear is connected to one end of the turntable's intermediate shaft via a synchronous belt.

[0011] Optionally, one end of the other bevel gear and the intermediate shaft of the turntable are both fixedly connected to a pulley for synchronous belt drive.

[0012] Optionally, the two smoothing rollers are positioned in the middle of the two pressure rollers.

[0013] Optionally, a protective shell is installed on one side of the mounting plate surface, and the bevel gear set and the rotating rod are both disposed inside the protective shell. One end of the rotating rod passes through the protective shell and is connected to the output shaft of the motor.

[0014] Optionally, a mounting frame is mounted on the other side of the mounting plate surface, and a bearing for rotating the turntable's intermediate shaft is mounted on one side of the mounting frame.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] 1. This utility model uses a rotating rod, a sliding ring, and a smoothing roller. The rotating rod drives the rotating rod to rotate, and the sliding rod connected to one end of the rotating rod slides inside the sliding ring, causing the sliding ring to move back and forth repeatedly. The T-shaped rods connected to both sides of the sliding ring drive the smoothing roller to repeatedly smooth the PET protective film, avoiding incomplete flatness.

[0017] 2. This utility model uses an anti-tilting plate, a turntable, and a movable plate. The rotation of the turntable drives the rotating rod D connected to the surface support rod to move the movable plate up and down, causing the rotating rod B to deflect. This causes the connecting plate to move left and right, causing the rotating rod A to deflect. This causes the anti-tilting plate to come into contact with the surface of the take-up roller, smoothing the edge of the PET protective film wound on the surface of the take-up roller and preventing it from warping due to tension.

An opening for the rotating rod B12 to pass through is provided in the middle of the mounting plate. A moving plate 13 is rotatably connected to one end of the rotating rod B12. A rotating rod C is rotatably connected to one end of the moving plate 13. A rotating rod D is rotatably connected to one end of the rotating rod C. One end of rod D is connected to a support rod, and the other end of the support rod is connected to a turntable 14. A mounting frame is installed on the other side of the mounting plate surface. The bottom of the mounting frame has a through-hole that communicates with the opening on the mounting plate. A bearing for the rotation of the intermediate shaft of the turntable 14 is installed on one side of the mounting frame.

A mounting shell is installed on the surface of the mounting plate. The other bevel gear and one end of the rotating rod are rotatably connected in the mounting shell. The other bevel gear and one end of the intermediate shaft of the turntable 14 are fixedly connected to a pulley for synchronous belt drive. A slot for the other bevel gear to pass through is opened on one side of the protective shell.

[0025] The implementation principle of the PET protective film leveling device in this embodiment is as follows: The PET protective film is unwound by the unwinding roller 2 and moved to the bottom of the pressure roller 3 for pressing. The motor is started, causing the rotating rod 4 to rotate. The rotating rod 4 drives the rotating rod 5 to rotate. The sliding rod connected to one end of the rotating rod 5 slides in the sliding ring 6, causing the sliding ring 6 to move back and forth repeatedly. The T-shaped rods 7 connected to both sides of the sliding ring 6 drive the smoothing roller 8 to smooth the PET protective film repeatedly. The rotation of the rotating rod 4 drives the turntable 14 to rotate. The smoothed PET protective film is wound up by the take-up roller 9. The rotation of the turntable 14 drives the rotating rod D connected to the surface support rod to drive the moving plate 13 to move up and down, causing the rotating rod B12 to deflect. This causes the connecting plate 11 to move left and right, causing the rotating rod A to deflect. This causes the anti-warping plate 10 to come into contact with the surface of the take-up roller 9, smoothing the edge of the PET protective film wound on the surface of the take-up roller 9 and avoiding the occurrence of warping due to tension.
