Abstract

The invention provides a copper wire unwinding machine. A copper wire needs to be clamped into a rubber sealing strip for an automobile in the extrusion process, and due to the fact that the shrinkage ratio and rigidity of the copper wire are higher than those of rubber, length contraction of the rubber sealing strip due to environment temperature change can be avoided. In an existing rubber sealing strip extrusion technology process, the copper wire is forcefully pulled into an extruding machine, the copper wire is stretched to generate tension before entering the extruding machine and is further clamped into the sealing strip with the tension, and bending deformation of a final product can be caused. The copper wire unwinding machine provided by the invention is provided with a copper wire speed adjusting unit, so that the unwinding speed of the copper wire is consistent with the extruding speed of the rubber sealing strip, stretching tension of the copper wire is removed, and the condition that the rubber strip is subjected to bending deformation and cannot be used due to the speed or tension difference of the rubber strip and the copper wire is effectively avoided.

Description

technical field

[0001] The invention belongs to the field of auto parts processing, and in particular relates to a copper wire unwinding machine. Background technique

[0002] Rubber sealing strips for automobiles need to be sandwiched with copper wires during the extrusion process, because the expansion rate and rigidity of copper wires are greater than those of rubber, so as to avoid the length shrinkage of the rubber strips due to changes in ambient temperature; the extrusion process of existing rubber sealing strips is forced The copper wire is pulled into the extruder, and the copper wire is stretched before entering the extruder to generate tension, and the tension is clamped into the sealing strip, causing the final product to bend and deform, making it unusable and urgently in need of improvement. Contents of the invention

[0003] The problem to be solved by the present invention is to provide a copper wire unwinding machine, the unwinding speed of the copper wire...
