In view of the above, a first aspect of the present invention provides an embodiment of a cut forming screen, as shown in fig. 1, comprising

A lower frame 2;

a screen body 5 laid on the upper surface of the lower frame 2;

an inner frame 3 located right above the lower frame 2 and fixed to the lower frame 2 by a plurality of bolts for fixing the screen body 5 between the lower frame 2 and the inner frame 3;

the upper frame 1 is sleeved outside the inner frame 2, and gaps 4 are arranged between each inner side wall of the upper frame 1 and the corresponding outer side wall in the inner frame 3;

and a cutting mechanism 8 for cutting off a portion of the screen body 5 extending to the outside of the lower frame 2 while sliding along the gap 4, and fixing the upper frame 1 to the lower frame 2 by bolts after the cutting off is completed.

When the screen cloth is used, the screen cloth body 5 is firstly paved on the upper surface of the lower frame 2, the inner frame 3 is fixed right above the lower frame 2 through a plurality of bolts, the screen cloth body 5 is fixed between the lower frame 2 and the inner frame 3, the upper frame 1 is sleeved outside the inner frame 3, a gap 4 is formed between each inner side wall of the upper frame 1 and the corresponding outer side wall in the inner frame 3, the screen cloth body 5 slides along the gap 4 through the cutting mechanism 8, the part of the screen cloth body 5 extending to the outside of the lower frame 2 is cut off, after the cutting is completed, the upper frame 1 is fixed on the lower frame 2 through the bolts, and therefore, after the part of the screen cloth body 5 extending to the outside is cut off, even if part of the part.

As an embodiment of the present invention, as shown in fig. 1, the widths of the gaps 4 corresponding to the inner sidewalls of the upper frame 1 are equal, so that the inner frame 3 is positioned at the middle position of the upper frame 1, and the appearance is more beautiful.

As an embodiment of the present invention, as shown in fig. 1, 5, 6 and 7, the cutting mechanism 8 includes a sliding block 81, a bottom block 87 and a cutting knife 88, stabilizing grooves 7 are provided on both sides of the gap 4, one of the stabilizing grooves 7 is located on the upper surface of the upper frame 1, the other stabilizing groove 7 is located on the upper surface of the inner frame 3, the bottom end surface of the sliding block 81 is provided with at least one of the cutting knives 88, and both sides of the bottom end surface of the sliding block 81 are provided with the bottom block 87 slidably connected with the stabilizing grooves 7.

In this embodiment, during cutting, the bottom block 87 is first engaged with the stabilizing groove 7, and then an external force is applied to slide the slider 81 along the corresponding gap 4, during the sliding process, the cutting knife 88 cuts the screen body 5, and after one of the gaps 4 is cut, the corresponding portion of the screen body 5 is sequentially cut in the other gaps 4.

As another embodiment of the present invention, as shown in fig. 6, two cutting knives 88 are provided and are arranged along the sliding direction of the sliding block 81, so that even if the cutting knife 88 located at the front in the sliding direction does not cut the screen during cutting, the cutting knife 88 located at the rear moves to a non-cutting position, the screen is cut, and the cutting efficiency is ensured.

As another embodiment of the present invention, as shown in fig. 6, each of the cutting knives 88 has two blades, and the cross section of the two blades is V-shaped, and the cutting mechanism 8 may not be completely split when sliding in the gap 4 once, at this time, because the cutting knife 88 has two blades and the cross section of the two blades is V-shaped, the cutting knife can slide back and forth in the gap 4, and after multiple cuts, the screen body 5 is completely cut.
