Background

The wire rod is widely applied to various fields, and in the production and processing, different products such as a data line, an earphone wire, a power supply wire, a plug connecting wire and the like are often manufactured after a long wire rod is cut. For the wire materials of the net wire, the shield wire and the like, the wire material structure from the outside to the inside usually comprises rubber, braided metal wire, an aluminum foil layer, breakage-proof wire and a wire core. When the wires are processed, the wires need to be cut off firstly, then rubber of the wire ends of the wires are stripped, then the metal braided wires are scattered, then the metal braided wires are tightly twisted together, then the aluminum foil layer is removed, and finally the anti-breaking wires are cut off to expose the wire cores of the wires.

The wire twisting and braiding machine is a device for processing the end of a wire, and in the prior art, the wire twisting and braiding machine can peel rubber and twist and braid metal wires of the wire. However, the wire twisting and knitting machine in the prior art cannot remove the aluminum foil of the wire, and the aluminum foil needs to be removed manually or by a special aluminum foil removing tool, so that the overall automation degree is low, and the processing efficiency is low.

For example, the patent number "CN 201820813476.0" of an aluminum foil removing device for a wire twisting and knitting machine disclosed in the chinese patent network is that although the aluminum foil removing device can mechanically and automatically remove the aluminum foil, the aluminum foil removing device is not fine enough or cannot cut the foil, or is easy to damage the core wire inside, and the foil is difficult to be removed and the core wire is not damaged.

Among the above-mentioned technical scheme, still include peeling mechanism.

In the technical scheme, the peeling mechanism comprises a peeling machine bracket and a clamp.

The utility model has the advantages that: the first blade and the second blade in the cutting device clamp the wire rod through relative movement to enable the shielding layer on the wire rod to press to the sharp edge of the first blade to form suspended cutting, and the second blade is elastically clamped, so that the elasticity of the spring is small, the force pressing to the sharp edge of the first blade is small, the wire rod can only cut the shielding layer, and the core wire under the shielding layer cannot be damaged; after cutting is completed, the wire is conveyed to a gap formed in the middle of the clamp of the peeling mechanism, the clamp clamps one end of the wire which is cut by the cutting blade to rotate for one circle, the wire is withdrawn, and the shielding layer is completely peeled. The shielding layer can be cut off, and the core wire in the shielding layer can not be damaged.

Detailed Description

The present invention will be described in further detail with reference to fig. 1-3.

The first blade 2 and the second blade 3 in the cutting device 1 clamp the wire 12 through relative movement to enable the shielding layer on the wire to press to the sharp edge of the first blade to form suspended cutting, and the elastic force of the elastic clamping is very small because the second blade is elastically clamped, so that the force pressing to the sharp edge of the first blade is very small, only the shielding layer can be cut, and the core wires under the shielding layer cannot be damaged; after cutting, the wire rod is conveyed to a gap formed in the middle of the clamp of the peeling mechanism 9, the clamp clamps one end of the wire rod which is cut by the cutting blade to rotate for one circle, the wire rod 12 is withdrawn and pulled out, and the shielding layer is completely peeled. The shielding layer can be cut off, and the core wire in the shielding layer can not be damaged. The shield layer may be a foil such as, but not limited to, aluminum foil. The peeling mechanism comprises a peeling machine bracket 10 and a clamp 11.

The first blade and the second blade form a clamping knife edge of the wire material shielding layer. One end of the first blade is a sharp edge used for cutting the aluminum foil, and the second blade is elastically clamped through the elastic piece. The elastic member may be one of a tension spring type, a compression spring type, a torsion spring type or a pneumatic type, and is preferably a compression spring type.

Wherein, relative motion is formed between the first blade and the second blade through one of a pneumatic finger clamping mode, a two-cylinder clamping mode and a gear meshing mode, and the pneumatic finger is optimized.

Fig. 2 is a specific embodiment of the present invention, a first support 4, a second support 5 and a pneumatic finger device are respectively disposed on two sides of the cutting device, one end of the first blade is fixedly connected to the first support, the other end is a sharp edge, the sharp edge is preferably designed into a "V" shape to facilitate cutting, and the sharp edge is sharp; the second blade is fixedly connected with a prepressing block 6 arranged on the second support, a through hole is arranged on the prepressing block, and a spring pin 7 which sequentially penetrates through the spring 8 and the through hole on the prepressing block and is fixedly connected with the second support through threads is arranged on the second support. The tightness of the spring is realized by adjusting the tightness of the screw spring pin. First blade and second blade pass through pneumatic finger centre gripping wire rod, make wire rod aluminium foil layer press to the "V" shape sharp edge of first blade, form unsettled cutting, because second blade and pre-compaction piece fixed connection, and pre-compaction piece one side connecting spring, and the elasticity of spring design is very little, and the power of pressing to first blade sharp edge that makes is very little, only can cut the aluminium foil layer, and can not hinder the heart yearn silk under the aluminium foil layer. After cutting is completed, the wire rod is conveyed to a gap formed in the middle of the clamp of the peeling mechanism, the clamp clamps one end of the wire rod which is cut by the cutting blade to rotate for one circle, the wire rod is pulled back, and the aluminum foil layer is completely peeled. The aluminum foil layer can be cut off, and the core wire in the aluminum foil layer can not be damaged.

The above embodiments are merely illustrative and not restrictive, and all equivalent changes and modifications made by the methods described in the claims are intended to be included within the scope of the present invention.
