Description

Cutter assembly and coil stock plastic pin aircraft nose thereof Technical Field The utility model relates to the technical field of rubber needle machining, in particular to a cutter assembly and a rubber needle machine head for rolling materials. Background The machine head of the coil stock glue needle machine is a key equipment component for processing glue needles in the process of nailing labels on textiles, and bears a series of important operations such as conveying, cutting off and matching with the follow-up nailing labels, and the performance of the machine head directly influences the overall efficiency and quality of conveying, cutting off and nailing labels on the coil stock glue needles. The inside of the existing needle machine head usually adopts a single cutter to cut the needle. However, the effect of cutting off the rubber needle is not ideal in practical application, the phenomenon that the rubber needle is not completely cut off often occurs, and part of the rubber needle still has connection residues, so that the head of the coil stock rubber needle machine can not normally feed the rubber needle, the quality of a nailed product is unqualified, and the reworking rate in the production process is increased. The problem that the cutting of the rubber needle is incomplete can occur, and the main reason is that the stress point of the single cutter is single in the shearing process, and when the material of the rubber needle is hard or the diameter is slightly large, the single cutter is difficult to provide enough uniform and strong shearing force, so that the rubber needle cannot be completely cut off at one time. Meanwhile, the single cutter is easy to wear after long-term use, so that the shearing accuracy and force are further reduced, and the problem that the rubber needle is not thoroughly cut off is more remarkable.
