Abstract

The invention discloses a locating shaft for forming incisions. The locating shaft comprises a locating shaft body, wherein a shaft sleeve is sleeved on the locating shaft body; the shaft sleeve is provided with a needle body along the circumference of the locating shaft body; the needle body is divided into a needle head and a needle seat; the needle head faces to the outer side wall of the shaft sleeve; the needle seat and the shaft sleeve are connected through a spring. A special electric motor does not need to be arranged, and obligated intermission time is also not needed. The shaft sleeve is sleeved on the locating shaft body, the shaft sleeve is connected with the needle body, the needle body contacts with packaging bags or paper on a conveyor belt, and the conveyor belt drives the shaft sleeve to rotate, so that the incisions are formed. The needle body and the shaft sleeve are connected through the spring, and the height can be adjusted by oneself in the free deformation range of the spring so as to be suitable for the packaging bags or paper with different thicknesses.

Description

technical field [0001] The present invention belongs to the technical field of packages. Background technique [0002] In order to facilitate tearing, many packaging bags or paper products are equipped with cut marks. At present, the indentation is realized by the intermittent movement of the cutting knife, which requires a special motor to control the cutting knife. Not only does it need to reserve Intermittent time, and waste of cost, thereby increasing the cost of production. Contents of the invention [0003] The invention provides a positioning shaft for forming a cutting mark, so as to solve the problem that the existing indentation needs a cutting knife to form. [0004] In order to solve the above-mentioned technical problems, the present invention provides the following technical solutions: A positioning shaft for forming cut marks, comprising a positioning shaft body, a shaft sleeve is sleeved on the positioning shaft body, and the shaft sleeve is provided along...
