Description

Technical Field

[0001] The utility model relates to the technical field of plate sawing, in particular to a knife clamping prevention device for large plate sawing equipment. Background Art

[0002] Doors, windows, furniture and other products usually require a large number of panels. When the factory conducts mass production, the panels are cut and sawed into the required panel size. During the sawing process of large panels, the cutting knife will cut into the raw material and continue to advance for a long distance.

[0003] However, since an opening has been formed at the beginning of cutting of the large plate, when the cutting knife continues to advance and move away from the opening position where the plate is cut, the opening positions of the plate are prone to approach each other and offset. The longer the plate, the greater the offset. As a result, the cutting knife is offset after the plate is cut, resulting in a knife clamping phenomenon, which can easily cause damage to the cutting knife and affect its use. In addition, when the plate is cut, the cutting knife will be exposed outside, which is more dangerous. Therefore, a knife clamping prevention device for large plate sawing equipment is proposed. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides an anti-knife clamping device for large-scale plate sawing equipment, which solves the problem that the opening positions of the plates are easily close to each other and offset. The longer the plate, the greater the offset. This causes the cutting knife to be offset after the plate is cut, resulting in the phenomenon of knife clamping and the cutting knife being exposed to the outside, which is more dangerous.
