[0024] Under the existing technology, static electricity is generated during the film processing on the production line, which makes it impossible to roll up the film flat during subsequent processing and affects the subsequent use of the film.

[0025] In order to solve the above problems, Figures 1 to 3As shown, the utility model provides a device for eliminating static electricity of a film, which includes a conveying platform 1, which is used to convey the film; an electrostatic elimination component, which is arranged on the top of the conveying platform 1, and the electrostatic elimination component includes a bracket 2, a liquid storage tank 4 installed on the bracket 2 and an atomizing spray head 11 connected to the liquid storage tank 4, the bracket 2 cover is arranged on the top of the conveying platform 1, the atomizing spray head 11 faces the direction of the conveying platform 1, and a stirring rod 5 is provided at the bottom of the liquid storage tank 4. The upper end of the stirring rod 5 extends toward the interior of the liquid storage tank 4, and the lower end of the stirring rod 5 passes through the liquid storage tank 4 and extends toward the conveying platform 1. The lower end of the stirring rod 5 is installed with a fan blade 8, the atomizing spray head 11 and the fan blade 8 are arranged in sequence along the conveying direction of the film, and a driving component 6 is also provided at the bottom of the liquid storage tank 4, which is driven and connected to the stirring rod 5, and the driving component 6 drives the stirring rod 5 to rotate.

[0026] A conveyor belt 16 is provided on the conveyor platform 1, and the conveyor belt 16 is used to transport the film. When the film passes the lower side of the bracket 2 along the conveyor belt 16, the antistatic liquid in the liquid storage tank 4 will be drawn out into the atomizing spray head 11, so that the liquid antistatic liquid becomes mist, and finally drips onto the film on the lower conveyor belt 16, eliminating the static electricity on the film.

[0027] Since the film needs to be kept dry during the subsequent processing, the antistatic liquid on the upper side of the film needs to be air-dried. The driving component 6 drives the stirring rod 5 to rotate, so that the fan blades 8 rotate, and the wind blown by the fan blades 8 can dry the antistatic liquid droplets on the film, which is convenient for subsequent processing. At the same time, the upper side of the stirring rod 5 is inserted into the liquid storage tank 4 to stir the antistatic liquid in the liquid storage tank 4, so that the antistatic liquid is more uniform to avoid precipitation, thereby maintaining the antistatic liquid's antistatic effect.

[0028] The drive member 6 of the present invention includes a motor 61, the output shaft of which is mounted a first bevel gear 62. A second bevel gear 63 is mounted on the stirring rod 5, and the first bevel gear 62 and the second bevel gear 63 are meshed. The motor 61 drives the first bevel gear 62 to rotate, which in turn rotates the meshed second bevel gear 63, ultimately driving the stirring rod 5 to rotate, which can simultaneously drive the fan blades 8 and the stirring portion 51 to rotate. This simplifies the power source within the thin film static elimination device and streamlines the structure. Only one motor 61 is required to simultaneously drive the fan blades 8 and the stirring portion 51 to rotate.

[0029] A base 3 is formed between the liquid storage tank 4 , an installation layer is formed inside the base 3 , a driving component 6 is installed on the installation layer, and an air vent is opened on the base 3 , a heat dissipation net 15 is installed in the air vent.

[0030] The motor 61, the first bevel gear 62 and the second bevel gear 63 are installed in the installation layer. After the liquid storage tank 4 is removed, the parts in the installation layer can be repaired, which is convenient for the staff to inspect and repair all parts and reduce the number of disassembly and assembly.

[0031] The installation layer is also provided with a water pump 9, and the liquid storage tank 4 and the atomizing spray head 11 are connected through the water pump 9. The water pump 9 is used to transport the antistatic liquid in the liquid storage tank 4 to the atomizing spray head 11, so that the antistatic liquid can be continuously delivered. The water pump is integrated in the installation layer, which makes the thin film static elimination device of the utility model more integrated.

[0032] A stirring portion 51 is installed on the upper end of the stirring rod 5. The stirring portion 51 is U-shaped and includes multiple groups. The size of each group of stirring portions 51 is different, so that the stirring portion 51 can stir the antistatic liquid in different areas of the liquid storage tank 4, making the antistatic liquid more uniform, and spraying it on the film can achieve the effect of removing static electricity.

[0033] A baffle 14 is installed between the fan blade 8 and the atomizing spray head 11. When the fan blade 8 rotates, the baffle 14 prevents the antistatic liquid sprayed from the adjacent position from entering the area under the fan blade 8, so that the area under the fan blade 8 can be blown dry separately, making the air-drying effect of the fan blade 8 better.

[0034] An observation window 13 is provided on one side of the liquid storage tank 4, through which the content of the antistatic liquid inside the liquid storage tank 4 can be observed. When the liquid level is low, the staff can add it according to the liquid level height. At the same time, the scale line 7 on the observation window 13 can control the amount of antistatic liquid added so that the staff can make subsequent markings.

[0035] The base 3 of the conveying platform 1 of the present invention is equipped with a support foot 12, and a rubber pad is installed at the bottom of the support foot 12. By providing the rubber pad, the friction between the film static elimination device and the ground can be increased, making the film static elimination device more stable during operation.

[0036] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
