[0025] Working principle:

[0026] The device cuts the glass fiber mesh cloth by cutting the glass fiber mesh cloth that falls vertically, and can be wound up by the winding roller 2, which saves the area occupied by the glass fiber mesh cloth during the flat cutting process, and the debris will not fall on multiple positions on the stage, which is convenient for collecting and cleaning the debris.

[0027] When cutting the glass fiber mesh cloth in the present device, the glass fiber mesh cloth needs to be wound on the reel 2, and the reel 2 is driven by the drive motor 5 to reel or unreel. When unreeling, the drive motor 5 works at a fixed time and a fixed speed each time, so as to control the unreeling length of the glass fiber mesh cloth to remain consistent;

[0028] In case of rewinding, the entire glass fiber mesh cloth is mostly on the loading platform, and then one end of the glass fiber mesh cloth passes through the gap between the pressing roller 3 and the frame 1, and is attached to the pad 6 and then fixed on the reel 2. The rewinding and cutting glass fiber mesh cloth method has the disadvantages that the debris is difficult to fall into the debris collection box 13, and most glass fiber mesh cloths require a larger loading platform, resulting in a larger occupied area.

[0029] In the case of unwinding, most of the entire glass fiber mesh cloth is wound on the roll 2, and then a part of the bottom of the glass fiber mesh cloth is on the front of the frame 1 and passes through the gap between the pressure roller 3 and the frame 1. Although the unwinding and cutting method is convenient for collecting debris, it is difficult;

[0030] Therefore, in this scheme, the glass fiber mesh cloth is cut by first winding up and then unwinding. By winding up first, the glass fiber mesh cloth passes through the gap between the pressure roller 3 and the frame 1 during the process of being pulled upward, which plays a role in smoothing the surface of the glass fiber mesh cloth. During the unwinding process, the bottom end of the glass fiber mesh cloth is manually pulled out from the gap between the pressure roller 3 and the frame 1, and then when the driving motor 5 drives the winding roller 2 to unwind, the glass fiber mesh cloth will naturally unwind and fall downward under the action of gravity, which also facilitates the falling glass fiber mesh cloth to fall into the debris collection box 13 during the cutting operation.

[0031] In this solution, the glass fiber mesh cloth can be selected for rolling or unrolling cutting according to the size of the stage and the needs of the staff, and whether the surface of the glass fiber mesh cloth needs to be smoothed first can be selected according to whether the surface of the glass fiber mesh cloth is flat. In both cutting methods, a part of the glass fiber mesh cloth is cut off by the cutting knife 4 at the front of the frame 1;

[0032] The roller 3 is moved to the rear of the frame 1 and the roller 3 is moved to the rear of the frame 1. The roller 3 is moved to the rear of the frame 1 and the roller 3 is moved to the rear of the frame 1.

[0033] The cutting knife 4 thus cuts the glass fiber mesh cloth, and the other side of the glass fiber mesh cloth is attached to the pad 6. The cut glass fiber mesh cloth falls downward, and its debris also falls downward and falls into the debris collection box 13. The debris collection box 13 can be manually pulled out for cleaning. The cutting knife 4 and the knife holder 10 are both on the front outside of the frame 1, and the cutting knife mounting seat 11 and the knife holder 10 are bolted and fixed, which is convenient for disassembly and replacement of the cutting knife 4.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
