Automatic production line of solar cell panel packaging films

Abstract

The invention discloses an automatic production line of solar cell panel packaging films. The automatic production line comprises a screw extruder, a film casting machine, a thickness gauge, a traction machine and a film winding machine, the screw extruder is connected with the film casting machine through a melt connector, the thickness gauge is arranged on the rear side of the film casting machine, and a rubber film bracket is arranged between the thickness gauge and the traction machine. The film winding machine is arranged on the rear side of the traction machine. Division is achieved in the screw extruder through a spiral rib plate to form a spiral water cavity and a spiral water channel, and flow guide spiral sheets are arranged on a water conveying pipe. Semiconductor refrigeration cylinders are arranged on the inner cylinder walls of roller outer cylinders of a rubber roller and a pattern roller which conduct opposite rolling, and a flexible roller sleeve and an end face cam structure are arranged on the outer cylinder of the rubber roller in a sleeving mode. Automatic winding is driven through a driving device on a winding machine frame to form a wound product, and a fly-cutter cut-off mechanism, a pressing swing arm mechanism and a spare shaft pressing mechanism are further movably supported on the winding machine frame. The production line not only can achieve continuous production and is high in efficiency, but also is good in rubber film uniformity and high in product quality.

Description

technical field [0001] The present invention relates to a kind of mechanical equipment used for the production of solar cell module encapsulation film, especially relates to the automatic production line of solar cell encapsulation EVA adhesive film, POE adhesive film or EVA and POE coextrusion adhesive film. Background technique [0002] Solar energy is a green, non-polluting and inexhaustible energy source. Solar cell power generation is one of the most effective ways to solve the problems of global environmental pollution and energy shortage. The solar photovoltaic power generation system is mainly composed of three parts: solar cell modules, controllers and inverters. Solar cell modules are the core part of the photovoltaic power generation system. [0003] The packaging of solar photovoltaic modules is a key step in the production of solar cells. In order to ensure the service life and energy conversion efficiency of solar cells, it is necessary to use polymer films tha...

Problems solved by technology

[0006] Most of the current film winders adopt manual winding and unwinding methods. When a winding mandrel is fully wound, it must be stopped before performing complex manned operations such as changing rolls, winding and unloading, which is not only difficult To ensure the quality of coil and film products, and this operation requires a lot of labor and operation time, the yield rate is reduced, and the production efficiency is low, especially not suitable for continuous production of the whole process, and automatic control and automatic operation cannot be carried out. Adapt to the high-quality, high-efficiency and continuous production requirements of film products
