Description

Technical Field

[0001] The utility model relates to the technical field of plate protective films, in particular to a plate film winding device. Background Art

[0002] Sheet protection film is a protective film covering the surface of the sheet. This film is usually used to protect the sheet from scratches, contamination, damage or corrosion during transportation, storage, processing and installation. Sheet protection film is usually a temporary covering, and the film will be removed once the sheet reaches the destination or completes the relevant process.

[0003] This film is usually made of plastic or other similar materials and can be customized to fit different board types and sizes. Its main purpose is to ensure that the board maintains its good appearance and quality during production and transportation, reducing the risk of damage while providing a layer of protection to prevent the surface from being invaded by dust, moisture or other harmful substances.

[0004] The utility model patent with application number: CN202120736243.7 and publication number: CN214934408U (hereinafter referred to as "prior art 1") discloses an automatic winding device for sandwich panel protective film, including a frame, a mounting frame is fixedly installed on the top of the frame, and a support plate is fixedly installed at the lower part of the mounting frame, a cooling fan is fixedly installed above the support plate, a sliding seat is slidably installed on the front and rear sides of one side of the top of the frame, and a support frame is fixedly installed on the top of the sliding seat, a servo motor is fixedly installed above the support frame, and a guard plate is fixedly installed at the output end of the servo motor, and a winding rod is fixedly installed on the guard plate.

[0005] The specification of prior art 1 discloses an automatic winding device for a sandwich sheet protective film. When in use, the protective film can be wound by cooperating with the servo motor, the winding rod and the guard plate. However, in actual applications, the pressure roller mainly rotates by relying on the friction provided by the winding rod when winding the sheet protective film, and the surface of the pressure roller itself has a certain friction. If the distance between the two pressure rollers is too small, the sheet protective film will be stuck between the pressure rollers, and the winding rod will not be able to continue to wind the sheet protective film, and may even break the sheet protective film.

[0028] The film feeding device includes a mounting platform 103, a motor 104, two pressure rollers 105 and a pressure roller mounting frame 106. The mounting platform 103 is mounted on the bottom plate 101. The motor 104 and the pressure roller mounting frame 106 are both arranged on the mounting platform 103. The two pressure rollers 105 are arranged on the pressure roller mounting frame 106 in a rotating manner from top to bottom. The motor 104 passes through the pressure roller mounting frame 106 and is connected to the pressure roller 105 located below.

Since the film roll on the film roll disk 110 is fixedly connected to the sheet protective film 102, as the rotating shaft 108 rotates, the film roll disk 110 gradually rolls up the sheet protective film 102. In this process, the film rolling of the film roll disk 110 and the film feeding of the pressure roller 105 are carried out synchronously, so as to avoid the sheet protective film 102 being stuck between the two pressure rollers 105 and causing damage to the sheet protective film 102.

[0031] In some embodiments, the mounting platform 103 is connected to the base plate 101 with a damped sliding connection.

[0032] In actual use, the purpose of using the damping sliding connection is to prevent the mounting platform 103 from moving freely without the action of external force.

The chain 126 is sleeved on the meshing teeth of the driving sprocket and the driven sprocket 127.

[0042] When in use, the motor 109 rotates and drives the worm 125 to rotate. The worm 125 rotates and drives the worm wheel 123 to rotate, and then drives the rotating rod 124 to rotate. The rotating rod 124 rotates and drives the driving sprocket to rotate. Since the chain 126 is engaged with the meshing teeth on the driving sprocket and the driven sprocket 127, the driving sprocket will drive the driven sprocket 127 to rotate and then drive the rotating shaft 108 to rotate. The purpose of setting up the transmission mechanism is to facilitate the installation of various components.

In this embodiment, a tension rod 121 is further hinged on the bracket 107, and a stopper wheel 122 is further provided on the tension rod 121. The sheet protective film 102 is used to pass around the tension rod 121 and then be fixedly connected to the film reel 110;

[0049] During actual use, the staff will wrap the sheet protective film 102 around the bottom of the tensioning rod 121 and fix it to the film rolling disk 110, then rotate the tensioning rod 121 to tension the sheet protective film 102, and then after fixing the tensioning rod 121, drive the motor 104 and the motor 109 to reel in the sheet protective film 102.
