[0051] Furthermore, when cutting the edges and corners of the polyurethane screen, the polyurethane screen is neatly placed on the lower fixed plate 15, and then the electric hydraulic rod 28 is started. The output end of the electric hydraulic rod 28 pushes the upper fixed plate 13 to move downward to fix the polyurethane screen on the lower fixed plate 15, and then the first motor 11 is started. The first motor 11 drives the threaded rod 10 to rotate through two pulleys 17, and the threaded rod 10 drives the movable sleeve 18 to move to the right. The movable sleeve 18 synchronously drives the first slider 19 and the second slider 26 to move to the right through the second slide groove 25, and drives the heating wire 23 to move to the right.

[0052] Furthermore, when it is necessary to cut other surfaces, start the second motor 21, the second motor 21 drives the connecting shaft 5 to rotate, and the connecting shaft 5 drives the lower fixed plate 15 to rotate. Since the upper fixed plate 13 and the lower fixed plate 15 are indirectly fitted together, the lower fixed plate 15 will drive the upper fixed plate 13 to rotate as a whole through the polyurethane screen, so that the other surfaces of the polyurethane screen face the heating wire 23, thereby achieving the effect of automatically adjusting the cutting surface of the polyurethane screen, and there is no need to disassemble the polyurethane screen for surface adjustment, which reduces the labor intensity of the staff and improves the cutting efficiency. Subsequently, the first motor 11 is reversed to make the heating wire 23 return to cut the corners of the polyurethane screen. In this way, the four surfaces of the polyurethane screen are cut back and forth. The arc-shaped slide groove 4 and the two arc-shaped sliders 16 are provided to assist the overall rotation of the lower fixed plate 15, thereby improving the stability of the overall rotation of the lower fixed plate 15.

[0053] Working principle: When cutting the edges and corners of the polyurethane screen, the polyurethane screen is placed neatly on the lower fixed plate 15, and then the electric hydraulic rod 28 is started. The output end of the electric hydraulic rod 28 pushes the upper fixed plate 13 to move downward to fix the polyurethane screen on the lower fixed plate 15, and then the first motor 11 is started. The first motor 11 drives the threaded rod 10 to rotate through two pulleys 17, and the threaded rod 10 drives the movable sleeve 18 to move to the right. The movable sleeve 18 synchronously drives the first slider 19 and the second slider 26 to move to the right through the second slide groove 25, and drives the heating wire 23 to move to the right. When the heating wire 23 moves to the right, it will cut the edges and corners of the polyurethane screen through its own heat, and the cut edges and corners will fall into the waste collection box 6 through the rectangular groove, and roll down through the inclined surface of the waste collection box 6, so as to facilitate the subsequent processing of the edges and corners.

[0054] Furthermore, when it is necessary to cut other surfaces, start the second motor 21, the second motor 21 drives the connecting shaft 5 to rotate, and the connecting shaft 5 drives the lower fixed plate 15 to rotate. Since the upper fixed plate 13 and the lower fixed plate 15 are indirectly fitted together, the lower fixed plate 15 will drive the upper fixed plate 13 to rotate as a whole through the polyurethane screen, so that the other surfaces of the polyurethane screen face the heating wire 23, thereby achieving the effect of automatically adjusting the cutting surface of the polyurethane screen. There is no need to disassemble the polyurethane screen for adjustment, which reduces the labor intensity of the staff. Subsequently, the first motor 11 is reversed to make the heating wire 23 return to cut the corners of the polyurethane screen. The four surfaces of the polyurethane screen are cut back and forth in this way. The arc-shaped slide groove 4 and the two arc-shaped sliders 16 are provided to assist the overall rotation of the lower fixed plate 15.

[0055] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments.
