Carpet tufting machines generally include a base cloth output roller, a pile output roller, a tufting needle, a needle plate and a hooking mechanism . The fleece output from the fleece output roller is fed to the tufting needle through the thread feeding mechanism, the needle plate is arranged under the tufting needle, and the needle plate is correspondingly provided with a gap for the tufting needle to pass through up and down. The base cloth output by the cloth output roller slides horizontally along the needle plate, and the hooking mechanism is arranged below the needle plate. During operation, the base cloth slides horizontally along the needle plate, and at the same time, the tufting needle moves up and down with the pile thread and penetrates through the needle plate. The base fabric, its working principle is like a sewing machine, after that, the fleece running through the base fabric forms a loop and is hooked out by a hooking mechanism. powerplant .
However, the existing velvet knife 1' includes an upper horizontal edge and a lower horizontal edge, the front end portion of the upper horizontal edge is bent downward to form a barb portion, and the rear end portion of the upper horizontal edge is connected with the front end portion of the lower horizontal edge. The rear end of the lower horizontal edge is a plug-in tail, so that when the pile is hooked, the upper horizontal edge is inserted into the loop, and the yarn is hooked through the barb, but the loop cannot come out of the upper horizontal edge after being hooked. , and the hooking knife 1' is in continuous back-and-forth movement, that is, after hooking a loop, the hooking knife 1' needs to be re-extended to hook the next loop. If the lint comes out in time, it will accumulate on the velvet knife 1', so that the velvet knife 1' can no longer continue to lint . In the prior art, the usual practice is to set up another straight knife 2', and by driving the straight knife 2' to move up and down, to form shearing with the fleece-cutting knife 1', and to cut the loops, so that the loops can be cut in time. The tufting knife 1' is released from the tufting knife 1', which is convenient for the tufting knife 1' to carry out the next tufting operation, but this also causes the existing tufting machine to only produce the cut pile products that cut the loops, and cannot produce the cut pile products that do not cut the loops. Loop pile products with loop cut.
