BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Figure 1 It is a structural schematic diagram of the composite board production device provided by the utility model. DETAILED DESCRIPTION

[0018] To make the objectives, technical solutions, and advantages of the present invention more clearly apparent, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby stated that any directional terms such as "up," "down," "left," "right," "front," "back," "inside," and "outside" that appear or will appear in this document are based solely on the accompanying drawings and are not intended to limit the present invention.

[0019] like Figure 1As shown, an embodiment of the present invention provides a composite sheet production device for manufacturing photovoltaic front panels for lightweight solar panels. The composite sheet production device includes a conveying mechanism 100, a spreading mechanism 200, and a hot press forming mechanism 300. The spreading mechanism 200 is located above the conveying mechanism 100 and is used to convey a flattened substrate fabric 1. The spreading mechanism 200 is used to spread resin powder 2 on the substrate fabric 1. The hot press forming mechanism 300 is located on one side of the conveying mechanism 100 and performs hot press forming on the substrate fabric sprinkled with resin powder. Specifically, the conveying mechanism 100 can be one or more of a belt conveyor, a gear conveyor, or a roller conveyor. The hot press forming mechanism 300 includes an upper conveying unit 301 and a lower conveying unit 302. To prevent uneven distribution of the resin powder caused by static electricity, the feed inlet 303 of the hot press forming mechanism 300 is equipped with an electrostatic eliminator 304 disposed toward the upper conveying unit 301 and the lower conveying unit 302.

[0020] Specifically, the static eliminator 304 includes a first static eliminator 304a and a second static eliminator 304b. The first static eliminator 304a is positioned toward the upper conveyor unit 301, and the second static eliminator 304b is positioned toward the lower conveyor unit 302. Specifically, the upper conveyor unit 301 and the lower conveyor unit 302 may be one or more of a belt conveyor unit, a gear conveyor unit, or a roller conveyor unit. The first static eliminator 304a eliminates static electricity from the upper conveyor unit 301 to prevent the upper conveyor unit 301 from adsorbing the resin powder 2 on the substrate fabric 1 when it moves to the feed inlet 303, thereby causing the resin powder 2 to be scattered. The second static eliminator 304b eliminates static electricity from the lower conveyor unit 302, simultaneously eliminating static electricity from the substrate fabric 1 and the resin powder 2, to prevent static electricity from the lower conveyor unit 302 from adsorbing the resin powder 2 on the substrate fabric 1, thereby causing the resin powder 2 to be scattered.

[0021] In a preferred embodiment, the distance between the first static eliminator 304a and the upper conveying unit 301 is 30 mm to 600 mm. In the ventilation state, ions are blown out with the compressed air flow, and the distance between the first static eliminator 304a and the upper conveying unit 301 can be 100 mm to 600 mm. In the non-ventilated state, without air flow, the distance between the first static eliminator 304a and the upper conveying unit 301 is adjusted to 30 mm to 50 mm. By controlling the distance between the first static eliminator 304a and the upper conveying unit 301, the electrostatic dust removal effect is improved.

[0022] In a preferred embodiment, the distance between the second static eliminator 304b and the lower conveying unit 302 is 30 mm to 600 mm. In a ventilated state, ions are blown out with the compressed air flow, and the distance between the second static eliminator 304b and the lower conveying unit 302 can be 100 mm to 600 mm. In a non-ventilated state, without air flow, the distance between the second static eliminator 304b and the lower conveying unit 302 is adjusted to 30 mm to 50 mm. By controlling the distance between the second static eliminator 304b and the lower conveying unit 302, the electrostatic dust removal effect is improved.

[0023] The static elimination device 304 can be an ion blower, an ion air gun, an ion wind snake, an ion wind rod, etc. Preferably, the static elimination device 304 includes at least one ion air gun. The ion air gun can generate a large amount of airflow with positive and negative charges to neutralize the charges carried by the upper conveying unit 301 and the lower conveying unit 302. When the charges carried on the surface of the upper conveying unit 301 and the lower conveying unit 302 are negative charges, the ion air gun can attract the positive charges in the airflow. When the charges carried on the surface of the upper conveying unit 301 and the lower conveying unit 302 are positive charges, the ion air gun can attract the negative charges in the airflow, thereby neutralizing the static electricity on the surface of the upper conveying unit 301 and the lower conveying unit 302, thereby achieving the purpose of eliminating static electricity. Specifically, the compressed air pressure of the ion air gun is 50psi~70psi, and the ion balance is -50V~50V.

[0024] In a preferred embodiment, the static eliminator 304 is positioned parallel to the width of the substrate fabric 1. The static eliminator width of the static eliminator 304 is greater than the width of the substrate fabric. It is understood that the static eliminator width of the static eliminator 304 is the range over which the ions released by the static eliminator 304 eliminate static electricity across the width of the substrate fabric 1. This ensures a stable static eliminator range and improves the static eliminator's effectiveness on the substrate fabric. It is understood that the width of the substrate fabric 1 is the direction perpendicular to the plane of the substrate fabric and the transport direction. Specifically, the number of ion guns in the first static eliminator 304a is equal to or less than the number of ion guns in the second static eliminator 304b. Because the lower conveyor unit 302 is an active conveyor unit, the static electricity generated by it has a greater impact on the uniform distribution of the resin powder 2 on the substrate fabric 1. Optionally, the first static eliminator comprises two rows of ion gun groups arranged along the transport direction, and the second static eliminator comprises one row of ion gun groups arranged along the transport direction, with each row of ion gun groups comprising 1 to 10 ion guns.

[0025] The hot press forming mechanism 300 includes a heating unit, a hot press unit, and a cooling unit, arranged sequentially along the transport direction. The upper conveying unit 301 and the lower conveying unit 302 are located above and below the heating unit, the hot press unit, and the cooling unit, respectively. In a preferred embodiment, the hot press forming mechanism 300 also includes a cold press unit, which is located after the cooling unit to prevent warping caused by temperature drop and maintain the flatness of the formed sheet.

[0026] The spreading mechanism 200 includes a leakage unit 201 and a spreading unit 202. The spreading unit 202 is arranged below the leakage unit 201. The spreading mechanism 200 evenly spreads the resin powder 2 in the leakage unit 201 on the surface of the substrate fabric 1 by rotating the spreading unit 202. Specifically, the leakage unit can be a funnel and the spreading unit 202 can be a roller.

[0027] In addition, the composite board production device also includes a flipping mechanism, which is arranged on the side of the hot pressing forming mechanism 300 away from the transportation mechanism 100 along the transportation direction. The flipping mechanism is used to flip the board after hot pressing. The flipped board can be again passed through the transportation mechanism 100, the spreading mechanism 200 and the hot pressing forming mechanism 300 to compound the other side of the base material fabric 1 and the resin powder 2.

[0028] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
