EVA automatic feeding machine

Abstract

The invention relates to an EVA automatic feeding machine. The EVA automatic feeding machine comprises a base, a supporting platform, axle bases, a lower rotary shaft, a lower roller, a lower guiding board, an upper rotary shaft, an upper roller and an upper guiding board, wherein the supporting platform is connected with the base through a height adjustment mechanism; one axle base is arranged at each of the left and right ends of the supporting platform separately; the two axle bases are arranged in parallel; the axle base on the left side is provided with a servo motor; one end of the lower rotary shaft is connected with the servo motor while the other end of the lower rotary shaft is movably connected with the axle base on the right side; the lower roller is arranged on the lower rotary shaft in a sleeving manner; the lower guiding plate is fixedly connected between the two axle bases; the upper rotary shaft is connected with the two axle bases through lifting mechanisms; the upper roller is arranged on the upper rotary shaft in a sleeving manner; and the upper guiding plate is horizontally connected with the lifting mechanisms on the two sides. The EVA automatic feeding machine has the advantages of simple structure, easy manufacturing, practicability and high efficiency.

Description

technical field [0001] The invention relates to the technical field of photovoltaic module production, in particular to an EVA automatic feeding machine. Background technique [0002] A solar cell is a device that directly converts light energy into electrical energy through the photoelectric effect or photochemical effect. The photoelectric direct conversion method uses the photoelectric effect to directly convert solar radiation energy into electrical energy. The basic device of photoelectric conversion is a solar cell. A solar cell is a device that converts sunlight energy directly into electrical energy due to the photovoltaic effect. It is a semiconductor photodiode. When the sun shines on the photodiode, the photodiode will convert the sun's light energy into electrical energy, generating current. When many batteries are connected in series or in parallel, it can become a solar cell square array with relatively large output power. [0003] EVA plastic film is a diff...

AI Technical Summary

Problems solved by technology

[0003] EVA plastic film is a difficult process in the process of laying solar panels. At present, the traction and feeding device for plastic film is a large and small rollers arranged in parallel. The rollers rotate synchronously through metal wires to carry the plastic film. In this method, the metal wire is bent and rubbed for a long time, and it is easy to break; the second method is to set up and down the roller, and the metal wire is wound on the lower roller to pull the plastic film, but there are also problems, the plastic film is easy to block the material at the entrance, The metal wire is also easy to break, requiring a large amount of maintenance work
