Description

Technical Field

[0001] The present application relates to the field of cutting tables, and in particular to a cutting knife deviation correction mechanism for a cutting table. Background Art

[0002] Cutting machines are indispensable equipment for some light industries. According to traditional concepts, cutting machines are machines that use the force of machine movement to pressurize the die to perform punching processing on non-metallic materials. Modern cutting machines have undergone some changes, and advanced technologies such as high-pressure water jets and ultrasound have begun to be used in leather punching technology, but people still classify these devices as cutting machines. The cutting bed uses a cutting knife to cut the placed non-woven fabrics. Since the slender cutting blade works in a cantilever state without support, the rigidity of the blade is poor, and the force on both sides of the blade is asymmetric during cutting, or the cutting cloth is not tight, the cutting knife will move with the cloth, thereby forming a pulling force, and the force on both sides is uneven, which will generate lateral force. When the lateral force borne by the tool reaches a certain value, the blade will deform.

[0003] At present, when non-woven fabrics are cut, the multi-layer stacked non-woven fabrics are very tough, and the cut fabrics are not tight without a pressing mechanism, which can easily lead to skewed cutting. It is also inconvenient to fix the stacked fabrics during cutting, so we propose a cutter correction mechanism for a cutting table. Utility Model Content
