Abstract
Description
Technical Field
[0001] The invention relates to the technical field of PVC drawing wires, and in particular to a slitting device and method for a film drawing wire. Background Art
[0002] Film wire has the characteristics of high shrinkage, high transparency and good flexibility. It plays an important role in the wire industry for convenient unpacking. With the increase in demand, the slitting of film wire also causes certain difficulties. At present, film wire is cut at room temperature, and most of them are cut in air-conditioned workshops. Under low temperature conditions, the film will become relatively hard and brittle. Quality problems such as burrs or jagged edges will appear during continuous production, which seriously affects product quality. Therefore, there is an urgent need for a continuous production method that can ensure the quality of film wire.
[0003] The film has high flexibility and elasticity. During the slitting process, especially when slitting into thin lines in continuous production, it is easy to produce quality problems such as burrs and jagged edges. The burrs will make the product look ugly. At the same time, the shavings will be brought into the product during winding and will be attached to the surface of the customer's product during use. The jagged edges will seriously reduce the breaking strength of the wire and cause the wire to break during use.
[0004] In view of this, this application is filed. Summary of the invention
