Description

Technical Field

[0001] The utility model relates to the technical field of tufted carpet machines, in particular to a multi-directionally adjustable digitally controlled yarn cutting device for tufted carpet machines. Background Art

[0002] Tufted carpet machines are mechanical equipment used to produce tufted carpets. Tufted carpets are mechanically tufted by knitting a fiber fabric backing in an up-and-down reciprocating motion to form a loop pile or cut pile carpet surface. After the tufted carpet is woven, the yarn edges need to be trimmed to prevent the yarn from breaking or affecting the appearance.

[0003] The utility model, publication number CN216473896U, discloses a yarn cutting device for a CNC tufted carpet machine. A cylinder fixing plate is mounted on one end of the shear fixed shaft, and an extended cylinder is fixedly mounted on the outer surface of the cylinder fixing plate. This allows the device to have a multi-directional adjustment structure, enabling universal adjustment, thereby effectively ensuring the device's flexibility.

[0004] However, the above-mentioned device for cutting tufted carpet yarns still has the following problems during actual use: although the scissors are driven by the scissor cylinder to cut the yarn, due to the uneven distribution of the yarns during the weaving process, the yarns on the same end face may be bent, wrinkled, overlapped, etc., so a single pair of scissors is difficult to achieve the required smoothing effect. Similarly, the yarns may be bent due to pressure during the cutting process, resulting in uneven cut ends, which affects the aesthetics of the tufted carpet.

[0005] Therefore, we propose a multi-directional adjustable CNC tufted carpet machine yarn cutting device to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide a multi-directional adjustable CNC yarn cutting device for tufted carpet machines, in order to solve the problem that the existing method of cutting yarns by driving scissors with scissors cylinders is difficult to achieve the desired smoothing effect due to the uneven distribution of yarns during the weaving process, and the yarns on the same end face may be bent, wrinkled, overlapped, etc., and a single scissor can also cause the yarns to bend due to pressure during the cutting process, resulting in uneven cut ends and affecting the aesthetics of the tufted carpet.
