Description

Technical Field

[0001] This utility model relates to the field of purging device technology, specifically to an automatic purging device for wire production. Background Technology

[0002] Conductors typically refer to cable components used in power transmission and signal transmission. They are often made of conductive material wrapped in an insulating layer. The conductive material can be copper, aluminum, or other metals, used to transmit current or signals. The insulating layer can be heat-resistant insulating rubber, plastic, etc.

[0003] Most existing conductors require a purging device during their production process to clean the conductor insulation layer, preventing residual particles from affecting subsequent coating operations. When purging the conductor insulation, the conductor end is often fixed by a screw-driven clamp. Since the cleaning relies on gas, the sealing of the fixed end is crucial. Bolts are prone to loosening during use, creating gaps between the guide end and the exhaust end of the purging device, leading to gas leakage or conductor detachment. This disrupts the purging process and reduces production efficiency. Utility Model Content

[0004] The purpose of this invention is to provide an automatic purging device for wire production, so as to solve the technical problem that most existing purging devices are prone to loosening and falling off when fixing wires.

[0005] The technical problem to be solved by this utility model can be achieved through the following technical solution:

[0006] An automatic purging device for wire production includes an air source pump and an exhaust end disposed at the output end of the air source pump.

[0007] The exhaust end is provided with an air supply hose, and the exhaust hose is provided with a connecting end. One end of the connecting end is provided with a plug pipe that communicates with the exhaust end. The end of the connecting end with the plug pipe is provided with a sleeve. Three sets of stabilizing seats are provided at intervals on both sides of the sleeve. A screw is rotatably provided on the inner side of the stabilizing seat. A toothed ring is provided on the outer side of the screw. A pull rod is movably provided on the outer side of the stabilizing seat. A positioning block for limiting the toothed ring is provided at the bottom end of the pull rod. A return spring is sleeved on the outer side of the pull rod.

[0008] As a further embodiment of this utility model: the insertion tube is shaped like a hollow cone, the sleeve is located on the outside of the insertion tube, the toothed ring is located inside the stabilizing seat, and the reset spring is located on the outside of the stabilizing seat.

[0009] As a further embodiment of this utility model: the input end of the air source pump is provided with an air inlet, and the bottom of the air source pump is provided with a base.

[0010] As a further embodiment of this utility model: the outer side of the insertion tube is provided with several sets of spaced protrusions, and one end of the screw is provided with a fitting clamp that matches the insertion tube.

[0011] As a further embodiment of this utility model: a limiting guide rod is provided on the outer side of the fitting clamp, and the limiting guide rod passes through the outer side of the sleeve.

[0012] The beneficial effects of this utility model are:

[0013] In this invention, the tapered connector allows for the insertion of wires of different diameters, further expanding the applicability of the device. Several sets of spaced protrusions are provided on the outer side of the connector. When the wire is fitted onto the outer side of the connector, the protrusions cause a certain degree of deformation in the wire. The pressure generated by the wire deformation, combined with the protrusions, forms a good radial seal. The traction of the pull rod by the return spring allows the positioning block to engage with the toothed ring after the clamping plate has finished holding the wire, thus positioning the screw. This prevents the screw from deflecting during use, further ensuring that the clamping plate can stably hold and fix the wire, guaranteeing the firmness and sealing of the connection between the wire and the connector. This greatly facilitates purging operations and improves production efficiency. Attached Figure Description

[0020] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] like Figure 1-4As shown, an automatic purging device for wire production includes an air source pump 1 and an exhaust end 2 located at the output end of the air source pump 1. The air source pump 1 has an air inlet end 3 at its input end and a base 4 at its bottom. An air supply hose 5 is located at the output end of the exhaust end 2, and a connecting end 6 is located at the output end of the air supply hose 5. One end of the connecting end 6 has a connector 7 communicating with the exhaust end 2. The connector 7 is a hollow cone in shape, and several sets of spaced-apart protrusions 8 are arranged around its outer side. A sleeve 9 is located at the end of the connecting end 6 where the connector 7 is located, outside the connector 7. Three sets of stabilizing seats 10 are spaced apart on both sides of the sleeve 9. A screw 11 is rotatably mounted on the inner side. One end of the screw 11 is fitted with a clamping plate 12 that matches the insertion tube 7. A limiting guide rod 13 is mounted on the outer side of the clamping plate 12, and the limiting guide rod 13 passes through the outer side of the sleeve 9. A gear ring 14 is mounted on the outer side of the screw 11, located inside the stabilizer 10. A pull rod 15 is movably mounted on the outer side of the stabilizer 10. A positioning block 16 for limiting the gear ring 14 is mounted at the bottom end of the pull rod 15. A return spring 17 is sleeved on the outer side of the pull rod 15, located on the outer side of the stabilizer 10. When using the device, the wire to be purged is first sleeved onto the outer side of the insertion tube 7. Since the insertion tube 7 is a hollow cone, its… The diameter gradually decreases, so the connector 7 can accept wires of different diameters, further expanding the application range of the device. Several sets of spaced protruding rings 8 are provided on the outside of the connector 7. When a wire is fitted onto the outside of the connector 7, the protruding rings 8 cause the wire to deform to a certain extent. The pressure generated by the wire deformation, combined with the protruding rings 8, forms a good radial seal. Then, the operator can pull the lever 15 upwards, causing the return spring 17 to deform and be stretched. The positioning block 16 rises away from the toothed ring 14, thus releasing the fixation of the toothed ring 14. At this time, rotating the screw 11 drives the clamping plate 12 to clamp and fix the wire, thereby ensuring a secure connection between the wire and the connector 7. After ensuring the firmness and sealing of the wire, the pull rod 15 is released. Under the action of the return spring 17, the pull rod 15 and the positioning block 16 are reset. The positioning block 16 is re-engaged into the tooth gap of the toothed ring 14 to achieve the positioning of the screw 11. This prevents the screw 11 from deflecting during use and further ensures that the mating clamp 12 can form a stable clamping and fixing of the wire. This ensures the sealing of the wire when connected to the connector 7. The limit guide rod 13 can guide and limit the movement of the mating clamp 12 to prevent it from deviating. Finally, the air source pump 1 is started, and the air is delivered to the connector 7 through the exhaust end 2 and the air supply hose 5 to purge the inside of the wire.

[0022] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
