Technical Field

The utility model relates to film coating production equipment, in particular to a deviation correcting device for a coating machine.

Background

In the production process of solar cell panel back plate films and various film materials, a coating process is an indispensable key process. The film is generally processed using a coater. One end of the coating machine discharges materials and the other end of the coating machine receives the materials, and the materials are pulled to sequentially pass through a plurality of processes through rolling power of the material receiving end. The spreading length of coating machine material loading area usually reaches nearly hundred meters, and at the towed in-process of material area, because coating equipment's installation error and the fluctuation of material area width size, the material area can produce the skew of width direction, causes the damage in material area. And correcting devices are required to be installed at different stations for correction. Use limit baffle etc. to rectify usually among the prior art, the material area takes place the skew time can take place the extrusion with the baffle equally, leads to defects such as deformation easily.

Detailed Description

The following detailed description of embodiments of the utility model is provided in conjunction with the accompanying drawings:

as shown in the figure, the deviation correcting device for the coating machine comprises an upper support 1, a lower support 2, four parallel reversing rollers 3, a plurality of middle rollers 4, a steering plane 5, a stepping motor 6 and an infrared position sensor 7. The upper and

lower brackets

1,2 are horizontal brackets, and are respectively supported by a pair of reversing rollers by a bearing 8, the four reversing rollers are arranged in parallel and distributed in a rectangular shape, and the material belt 9 forms two vertical material belts and a horizontal material belt when moving around the outer side of a rectangular frame formed by the four reversing rollers. In order to accurately measure the offset of the material strip, an infrared position sensor 7 is mounted on the bottom surface of the upper bracket 1 near the side of the material strip 9 away from the rectangular frame. One side edge of the material belt 9 passes through the center of the infrared position sensor 7, and when the material belt 9 deviates, the infrared position sensor 7 feeds back a signal. The intermediate rollers 4 are distributed at the input and output of the strip 9 for adjusting the horizontal input and output of the strip.
