DETAILED DESCRIPTION

[0022] The following will be combined with the 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0023] Example 1

[0024] See also Figures 1 to 4 , which is the first embodiment of the present invention, and this embodiment provides a technical solution: a copper wire drawing machine, comprising

[0025] A wire drawing machine body 1, a plurality of wire drawing rollers 2 rotatably mounted on the inner side of the wire drawing machine body 1, a feed port 11 and a discharge port 12 respectively arranged on the surfaces of both sides of the wire drawing machine body 1, a feed roller 3 rotatably mounted on the inner side of the wire drawing machine body 1 and located at the feed port 11, a discharge roller 4 rotatably mounted on the inner side of the wire drawing machine body 1 and located at the discharge port 12, a winding roller 5 is also arranged on one side of the discharge roller 4, and the copper wire 6 is passed around the feed roller 3, the wire drawing roller 2, the discharge roller 4 and the winding roller 5 in sequence. The above structural principles are all technologies that have been disclosed in the prior art. For details, please refer to the existing patent with publication number CN111438207A, which will not be described in detail here;

[0026] And an adjustable antioxidant coating mechanism 7 is arranged on one side of the wire drawing machine body 1, the adjustable antioxidant coating mechanism 7 includes a movable base plate 72 movably installed on the top of the wire drawing machine body 1, a side support rod 75 fixed on the left surface of the movable base plate 72, an oxidant storage cylinder 77 welded and fixed to the bottom end surface of the side support rod 75, and a coating sponge 78 installed on the bottom surface of the oxidant storage cylinder 77, and a strip notch 781 is provided at the bottom of the coating sponge 78 for the copper wire 6 to pass through, so that the antioxidant can be coated when the copper wire 6 is drawn, thereby effectively improving the phenomenon that the copper wire 6 is easily oxidized during the drawing process.

[0027] In this embodiment, preferably, an inner groove 771 is provided in the oxidant storage tube 77, and an integrated cylindrical liquid-absorbing sponge rod 782 is provided on the top of the smear sponge 78. A circular bottom hole 773 communicating with the inner groove 771 is provided on the bottom surface of the oxidant storage tube 77, and the top of the cylindrical liquid-absorbing sponge rod 782 passes through the circular bottom hole 773 to the inner side of the inner groove 771. Because the cylindrical liquid-absorbing sponge rod 782 and the smear sponge 78 are both made of sponge material and have good liquid absorption properties, the antioxidant stored in the inner groove 771 can be effectively absorbed and smeared on the copper wire 6, so that the copper wire 6 can be coated with the antioxidant before drawing, thereby playing a certain antioxidant role in the subsequent drawing process of the copper wire 6. The antioxidant here can be a drawing emulsion.

[0028] In this embodiment, preferably, both side surfaces of the cylindrical liquid-absorbing sponge rod 782 are provided with an integrated side clamp block 783, and the side clamp block 783 is clamped on the inner wall of the bottom end of the inner groove 771, so that the cylindrical liquid-absorbing sponge rod 782 can be limited after being inserted into the inner groove 771, ensuring that the smear sponge 78 can be stably installed at the bottom of the oxidant storage cylinder 77.

[0029] In this embodiment, preferably, a top cover 76 is also installed on the top of the oxidant storage cylinder 77, and a rubber plug 761 is fixed to the bottom surface of the top cover 76. The rubber plug 761 is inserted into the inner groove 771 and seals the top opening of the inner groove 771. At a later stage, the top cover 76 can be regularly pulled off, and then antioxidants can be added to the inner groove 771.

[0030] In the present embodiment, preferably, a plurality of circular protrusions 772 are fixed to the inner wall of the top end of the inner groove 771, and an annular groove 762 for the circular protrusions 772 to be inserted into is opened on the surface of the rubber plug 761. Both the top cover 76 and the rubber plug 761 are made of rubber material, which will undergo elastic deformation when squeezed, so that after the rubber plug 761 is inserted into the inner groove 771, the circular protrusions 772 can be squeezed into the annular groove 762, thereby limiting the rubber plug 761 and ensuring the installation stability of the top cover 76. If the top cover 76 is to be pulled off later, it is only necessary to lift the top cover 76 with force, so that the rubber plug 761 is squeezed and elastically deformed, so that the circular protrusions 772 are squeezed out of the annular groove 762, and the rubber plug 761 can be smoothly pulled out of the inner groove 771.

[0031] In this embodiment, preferably, the adjustable antioxidant coating mechanism 7 also includes a base rod 71 welded and fixed on the top surface of the wire drawing machine body 1, and a movable base plate 72 is slidably mounted on the surface of the base rod 71, so that the movable base plate 72 can smoothly slide up and down on the top of the wire drawing machine body 1, and a pressure plate 74 is installed on the top surface of the base rod 71 relative to the upper part of the movable base plate 72, and a spring 73 is also mounted between the surface of the base rod 71 relative to the movable base plate 72 and the pressure plate 74. Under the push of the spring 73, the coating sponge 78 can keep in contact with the copper wire 6 at all times during daily use, so that the surface of the copper wire 6 is coated with antioxidant.

[0032] In this embodiment, preferably, a guide rod 13 is welded and fixed to the top surface of the wire drawing machine body 1 relative to the right side of the base rod 71, and the top end of the guide rod 13 penetrates to the top end of the movable base plate 72, which can provide guiding support when the movable base plate 72 slides up and down.

[0033] Example 2

[0034] See also Figures 1 to 5 The second embodiment of the present invention is based on the previous embodiment. The difference is that a top ring 741 is welded and fixed to the top surface of the pressure plate 74, and the top of the base rod 71 extends all the way to the top of the top ring 741. The surface of the top ring 741 is threadedly connected with a fastening bolt 742, and the threaded end of the fastening bolt 742 extends to the inner side of the top ring 741 and is in tight contact with the base rod 71 to fix the top ring 741 and the pressure plate 74. In the later stage, the fastening bolt 742 can be loosened to contact the limit of the pressure plate 74, and then the pressure plate 74 can be slid up and down to adjust the tightness of the pressure plate 74 to the spring 73, thereby adjusting the tightness of the spring 73 to the movable base plate 72, thereby adjusting the tightness of the smear sponge 78 and the copper wire 6. After the adjustment is completed, the fastening bolt 742 can be tightened and fixed again.
