Specific Embodiments

[0022] The present utility model will be further described below with reference to the drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present utility model and cannot be used to limit the protection scope of the present utility model.

[0023] The present utility model provides as Figures 1-4A film unwinding device for shipping as shown includes a bottom plate 1, a film unwinding device 2 disposed at the upper left end of the bottom plate 1 for unwinding a protective film, a film winding device 3 disposed at the upper right end of the bottom plate 1 for winding the protective film, and two side clamping assemblies located in the middle of the upper part of the bottom plate 1. A plurality of rotatable dust suction rollers 9 that can contact the surface of the protective film are installed at symmetric positions at the left end and the right end of the side clamping assemblies. U-shaped frames 7 are installed between the tops and the bottoms of the two side clamping assemblies. A transmission assembly for transporting and transferring ion wind is installed on the side of the U-shaped frame 7 away from the side clamping assemblies. An inner spray hood 16 that can penetrate through the middle of the U-shaped frame 7 and point to the middle of the side clamping assemblies is installed in the middle of the transmission assembly. A plurality of outer spray pipes 19 that can point to the film inlet direction of the protective film are installed at the left end of the transmission assembly. During the process of unwinding the protective film from the film unwinding device 2 at the left end to the film winding device 3 at the right end, the position of the side clamping assemblies is the unwinding exposure space of the protective film.

[0024] The side clamping assembly includes an intermediate plate 5 and two clamping plates 6 detachably installed at the top and the bottom of the intermediate plate 5. A plurality of round holes are formed by surrounding between the clamping plates 6 and the intermediate plate 5. A rotating shaft 8 is detachably and rotatably penetrated between two round holes on different sides. The dust suction roller 9 is detachably sleeved on the rotating shaft 8. The driving structure for the rotation of the rotating shaft 8 is not shown in the figure. During the actual operation process, the rotation of the rotating shaft 8 drives the rotation of the dust suction roller 9, thereby adsorbing and removing the air dust on the surface of the protective film.

[0025] The U-shaped frame 7 is detachably installed between the two clamping plates 6. The transmission assembly includes a U-shaped flow pipe 13 detachably clamped between the two U-shaped frames 7 and an air inlet pipe 14 disposed in the middle of the U-shaped flow pipe 13 for transmitting the ion wind generated by an ion blower into the U-shaped flow pipe 13. The air inlet pipe 14 can be connected to an external ion blower to transmit the ion wind for weakening static electricity into the U-shaped flow pipe 13.

[0026] Vertical pipes 15 are installed at the positions of the middle parts of the two sides of the U-shaped flow pipe 13 in the middle of the two U-shaped frames 7. The vertical pipes 15 longitudinally penetrate through the U-shaped frames 7, and the other ends of the vertical pipes 15 are detachably connected to the inner spray hood 16. The middle parts of the two side walls of the U-shaped flow pipe 13 are connected with a transfer cross pipe 18 through connecting pipes 17, and the transfer cross pipe 18 is located at the left end of the U-shaped frame 7. A plurality of outer spray pipes 19 are installed on the circumferential side wall of the transfer cross pipe 18. The vertical pipes 15 and the connecting pipes 17 can divide the ion wind in the U-shaped flow pipe 13, so as to flow to the inner spray hood 16 and the outer spray pipes 19 at the corresponding positions respectively.

[0027] On the left and right ends of two clamping plates 6 on different sides, side plates 20 can be detachably installed. A guide rail 10 is installed at one end of the side plate 20 pointing to the protective film. A plurality of sliding plates 11 are slidably arranged between two guide rails 10 on the same side. And the two sliding plates 11 are respectively located on both sides of the protective film. And an anti-deviation plate 12 for correcting the winding orientation of the protective film is installed at one end of the sliding plate 11 close to the protective film. During the winding process, by changing the position of the sliding plate 11 between the guide rails 10, the two anti-deviation plates 12 on both sides are forced to contact the side surface of the protective film, thereby avoiding the problem that the protective film runs off due to a large exposed space during winding.

[0028] Support columns 4 are installed at both ends of one side wall of the middle plate 5. The bottom end of the support column 4 is detachably connected to the top surface of the bottom plate 1.

[0029] In the present utility model, during the unwinding process of the protective film from the film unwinding device 2 at the left end to the film winding device 3 at the right end, the position of the side clamping assembly is the exposed space for unwinding the protective film. By transferring the protective film during the unwinding process into the side clamping assembly, on the entering side, ion wind is sprayed onto both surfaces of the protective film through a plurality of outer spray pipes 19 pointing to the film entering direction of the protective film, thereby weakening the static electricity on the surface of the protective film. When the protective film enters the side clamping assembly, on both the film entering side and the film exiting side, it contacts the surface of the protective film through rotatable dust suction rollers 9, thereby adsorbing and removing the dust already existing on the surface of the protective film. And in the middle of the side clamping, an inner spray cover 16 further sprays ion wind onto the surface of the protective film, that is, further weakening the static electricity on the surface of the protective film. Finally, by combining the weakening of surface static electricity by ion wind at multiple positions and the adsorption and removal of surface dust by the dust suction roller 9, the weakening of static electricity and the removal of dust are combined, ultimately improving the cleanliness of the surface of the protective film, ensuring the overall quality of the protective film during the winding process, and improving the subsequent shipment qualification rate.

[0030] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the technical principle of the present utility model, several improvements and deformations can be made, and these improvements and deformations should also be regarded as the protection scope of the present utility model.
