Description

A cable organizer that can always keep the spacing even

technical field

The invention belongs to the field of machinery, and in particular relates to a wire arranging device which can synchronize the speed of arranging wires with the speed of taking up wires through a PAC control system and can always keep a uniform row distance.

Background technique

The cable straightener is suitable for wire, cable, wire drawing, weaving and other industries. It is generally used in conjunction with the wire take-up equipment. At present, there are many types of cable arranging devices. Among many cable arranging device products, there are very few cable arranging devices that can withstand both radial force and axial force. Especially when high-precision cable arranging is required, many products have axial force. Due to the large force, the predetermined pitch cannot be guaranteed. Once the cable puller slides axially, the cables will inevitably overlap each other, which will not only affect the life of the cables that need to reciprocate, but may cause the cables to become dirty due to long-term abnormal friction. Danger of destruction. In addition, most of the current cable guides use electronic control equipment to control the slider to move left and right on the shaft. Since the cable will rub against the slider during the winding process, the local temperature at the friction point will be too high, which will easily damage the electronic control equipment. , thus destroying the take-up work.
