Description

Amplification mold core for cable binding machine

Technical Field

The utility model relates to a cable manufacturing field, in particular to an increase mold core for cable bundling machine.

Background

After the cable is formed, the cable is generally bundled to form a hollow cable coil, and the cable coil is transported and sold in an individual package. At present, the bundling of cables is mainly performed manually, workers wind the cables around the peripheral surface of a mold core, cut the cables after winding for a certain length, remove the wound cable coils from the mold core and fix the cable coils by using an adhesive tape, and finally sleeve the cable coils into a heat shrinkage bag and perform heat shrinkage treatment.

Although the manual bundling mode can meet the basic bundling requirement of the cable coil, the labor cost is high, the efficiency is low, and in order to reduce the labor cost and improve the bundling efficiency of the cable, the cable bundling machine is invented. As shown in fig. 1, the cable binding machine mainly includes a feeding module 10, a cutting device 20 and a binding discharging module 30, the cutting device is located between the feeding module and the binding discharging module, wherein the feeding module is provided with a feeding arm 11 capable of moving back and forth, a feeding channel 12 capable of allowing a cable to pass through is arranged in the feeding arm, and a clamping device 13 for clamping the cable is arranged behind the feeding channel of the feeding arm. The bundling and discharging module comprises a workbench 31, a lower rotary table 32, a lifting rotary mechanism 33 and a discharging mechanism 34, wherein the lower rotary table is rotatably connected to the upper surface of the workbench, the lifting rotary mechanism is connected with a mold core 35 to drive the mold core to lift up and down and rotate, the mold core is positioned right above the lower rotary table and comprises a mounting plate and a core part, the mounting plate is directly connected with the lifting rotary mechanism, and the core part is connected to the lower bottom surface of the mounting plate; the front and back of the discharging mechanism are movably connected to the workbench, the discharging mechanism is provided with a foldable discharging claw, and the moving path of the discharging claw is intersected with the lower rotary table.

When the cable binding machine is used for binding cables for the first time, the cables firstly penetrate through a feeding channel of a feeding arm and extend out for a certain distance, then a clamping device clamps the cables, then the feeding arm drives the cables to move forwards to the rear of a mold core together, one end of each cable is positioned under the mold core, a lifting rotating mechanism drives the mold core to press downwards to a lower rotating disc so as to compact one end of each cable, then the clamping device loosens the cables, the feeding arm resets backwards to the rear of a cutting device, then the lifting rotating mechanism drives the mold core to rotate so that the cables can be passively wound on the outer peripheral surface of the mold core, in the process, a discharging mechanism moves backwards to the side of the lower rotating disc, after a period of time, the lifting rotating mechanism stops rotating the mold core, the cutting device cuts the cables immediately, and finally the lifting rotating mechanism drives the mold core to move upwards away from the lower rotating disc, meanwhile, the discharging mechanism unfolds the discharging claw of the discharging mechanism and gradually moves forwards so as to discharge the cable coil on the lower turntable.

However, the inventor finds in practice that the cable is wound around the outer peripheral surface of the mold core, that is, the diameter of the inner ring of the cable coil is consistent with the outer diameter of the mold core, so that when the lifting rotating mechanism drives the mold core to upwards leave the lower turntable, the cable coil may possibly follow the mold core to upwards leave the lower turntable, the discharging mechanism cannot discharge the cable coil, and at the moment, manual discharging is needed, and the production rhythm is seriously affected.
