Description

Technical Field

[0001] The utility model relates to the field of cable processing devices, in particular to an integrated device for automatically cutting PE films of cables. Background Art

[0002] Many wires need to be cut into fixed lengths during processing. For example, the wire body of a data cable needs to be cut into fixed lengths during processing and then connected to the plugs at both ends.

[0003] At present, wires are usually cut into fixed lengths during processing and then bundled together with PE film for easy transportation. Currently, the cutting and bundling of wires are mostly done manually, which will cause a waste of manpower and increase production costs. Utility Model Content

[0004] The utility model aims to provide an integrated device for automatically cutting PE films of cables, which has the advantage of replacing manual work in completing the cutting and bundling of wires.

[0005] In order to achieve the above-mentioned purpose and other related purposes, the utility model provides the following technical solutions: a cable automatic PE film cutting integrated device, comprising:

[0006] Work surfaces;

[0007] A wire cutting mechanism guides the wire to move, cuts the wire into fixed lengths, and leaves the wire segments on the work surface, and sends a sensing signal after each cutting;

[0008] The wire gathering mechanism gathers multiple wires into bundles;

[0009] a film wrapping mechanism, used for carrying the PE film and winding the PE film around the wire bundle aggregated by the wire gathering mechanism; and

[0010] The controller presets the number of wires in each bundle, receives and stores the sensing signal sent by the wire cutting mechanism, and controls the wire gathering mechanism to gather the wires when the number of wires after cutting reaches a preset value.

[0011] Through the above technical solution, the wire cutting mechanism cuts the wire into a fixed length and the wire remains on the workbench. When the controller receives the sensing signal sent by the cutting mechanism and reaches the preset value, that is, the number of wires reaches the predetermined number of wires in a bundle, the wire gathering mechanism gathers all the segmented wires into bundles, and the wrapping mechanism wraps the PE film around the wire bundle, thereby realizing automated wire cutting and bundling work, replacing manpower, thereby avoiding waste of manpower and reducing production costs.

[0012] In one embodiment of the utility model, the wire cutting mechanism includes: a wire driving component that drives the wire to move in a directional manner along its length direction; a cutting driving component; a cutter driven by the cutting driving component to cut the wire; and a length detection component that detects the length of the wire driven by the wire driving component and sends a signal to the controller, and when the length of the wire driven by the wire driving component is a predetermined wire length, the controller controls the cutting driving component to cut the wire.

[0013] Through the above technical solution, the cutter pre-cuts the excess wire, and the wire drive assembly is controlled to drive the wire to move. At the same time, the length detection component detects the length of the moving wire and sends a signal to the controller. When the length of the moving wire is the same as the predetermined wire length, the cutting drive component drives the cutter to cut the wire, thereby realizing fixed-length cutting of the wire.

[0014] In one embodiment of the utility model, the wire driving assembly includes: a plurality of lead blocks, each of which has a lead hole through which the wire passes; a driving module, which applies a unidirectional force to the wire; and an extrusion module, which applies a force directed toward the driving module to the wire, thereby increasing the friction between the wires and enhancing the stability of the driving module.

[0015] Through the above technical solution, the wire passes through the lead holes opened on several lead blocks in sequence. The lead blocks limit the direction of the wire and the moving direction of the wire. After the extrusion module applies force to the wire, the driving module applies friction force to the wire to drive the wire to move in a directional manner.

[0016] In one embodiment of the present invention, the wire gathering mechanism includes: a fixed engaging member; an engaging driving member; and a sliding engaging member driven by the engaging driving member to slide and cooperate with the fixed engaging member to aggregate multiple wires.

[0017] Through the above technical solution, the engaging driving member drives the sliding engaging member to move in the direction where the fixed engaging member is located, and the sliding engaging member cooperates with the fixed engaging member to aggregate the wires into bundles.

[0018] In one embodiment of the utility model, the wrapping mechanism includes: a material strip holding component for holding a PE film material strip; a glue wrapping ring, on which a wire passing opening is provided; a positioning driving component, which drives the material strip holding component and the glue wrapping ring to slide synchronously, so that the wire material gathered by the wire gathering mechanism squeezes the PE film material strip so that the wire material and the PE film pass through the wire passing opening and reach the middle through hole of the glue wrapping ring synchronously, so that the PE film half-wraps the wire material; a coating driving component that drives the glue wrapping ring to rotate so that the glue wrapping ring squeezes and bends the PE film so that the PE film wraps the wire material; and a cutting component that separates the PE film wrapped around the wire material from the remaining part.

[0019] Through the above technical solution, after the wire gathering mechanism gathers the wires into bundles, the in-place driving component drives the material tape holding assembly and the rubber wrapping ring to slide so that the wires pass through the wire passing port and reach the middle through hole of the rubber wrapping ring, and the wires will first squeeze the PE film tape to make the PE film tape bend and half-wrap around the wires, and then the coating driving component drives the rubber wrapping ring to rotate, and during the rotation of the rubber wrapping ring, the PE film tape will be squeezed to make the PE film tape further bend and wrap around the wires, and then the cutting component will cut off the excess PE film to complete the PE film wrapping.

[0020] In one embodiment of the utility model, the material strip holding assembly includes: a mounting rod for holding the PE film material roll; a fixed clamp for clamping the remaining PE film material strip cut off by the cutting piece; a lead-out drive member; and a sliding clamp driven by the lead-out drive member, which slides and pulls out the PE film material strip after clamping the end of the PE film material strip. After the PE film material strip is pulled out by the sliding clamp, it is located on the moving path of the wire when it is aggregated by the wire gathering mechanism.

[0021] Through the above technical scheme, the PE film material roll is mounted on the mounting rod, and then the PE film material strip is led out and passed through the fixed clamp and the sliding clamp in sequence. After one coating is completed, the PE film is cut off, and the lead-out driving member drives the sliding clamp to slide, and the sliding clamp clamps the end of the PE film material strip. Then the fixed clamp releases the PE film, and the lead-out driving member drives the sliding clamp to slide and pull out the PE film material strip, preparing to coat the next group of wires.

[0022] In one embodiment of the present invention, the material strip holding assembly further comprises at least one material guide roller for guiding the PE film material strip pulled out from the PE film material roll into the fixed clamping jaw.

[0023] Through the above technical solution, the feed roller guides the direction of the PE film strip.

[0024] In one embodiment of the utility model, it also includes a feed conveyor belt, a discharge conveyor belt and a transfer assembly. The wire cut by the wire cutting mechanism is overlapped on the feed conveyor belt. The transfer assembly is used to transfer the wire overlapped on the feed conveyor belt to the work table. The wire bundle wrapped in PE film is transported to the subsequent workstation via the discharge conveyor belt.

[0025] Through the above technical solution, the wires are first cut and overlapped on the feed conveyor belt and then transferred to the work surface, so as to avoid the accumulation of wires hindering the subsequent wires from reaching the work surface and enhance the stability of equipment operation.

[0026] In one embodiment of the present invention, the transfer assembly includes: a transfer driving member; and a push plate driven by the transfer driving member to slide and push the wire from the feed conveyor belt to the work surface.

[0027] Through the above technical solution, after the wire is cut, the transfer drive member drives the push plate to slide, and the push plate pushes the wire to move so that the wire reaches the work table from the feed conveyor belt.

[0028] As described above, the cable automatic PE film cutting integrated device of the utility model has the following beneficial effects:

[0029] After the wire cutting mechanism cuts the wire into a fixed length, the wire remains on the work surface. When the controller receives the sensing signal sent by the cutting mechanism and reaches the preset value, that is, the number of wires reaches the predetermined number of wires in a bundle, the wire gathering mechanism gathers all the wire segments into bundles, and the wrapping mechanism wraps the PE film around the wire bundle, thereby realizing automated wire cutting and bundling work, replacing manpower, thereby avoiding waste of manpower and reducing production costs.
