[0002] Copper is a soft metal, and its surface exhibits red-orange color with metallic luster when freshly cut, and the elemental form is purple-red. Copper has good ductility, excellent thermal and electrical conductivity, which makes it one of the most commonly used materials in the manufacture of cables, electrical and electronic components. In addition, copper can also be combined with other metal elements to form various alloys.

[0003] In the production process of copper rods, in order to meet the needs of wire and cable manufacturing, a drawing device is usually used to process the copper rod.

Then, it will be smoothly passed out along the wire drawing die 13. After passing out, the copper wire will be guided by the guide component 14 and connected to the drum 16, so that the copper wire can be evenly wound on the outer circumference of the drum 16.

[0053] A limiting block 161 is slidably connected to the outer periphery of the drum 16, and a fixing screw 162 is threadedly connected to the outer periphery of the drum 16. A moving part 17 is installed on the top of the wire drawing box 11.

[0057] In order to prevent the drum 16 from causing the copper wire to be loose during the long time winding process, a set of adjustment mechanism is designed, when the copper wire is detected to be loose, the multi-section electric push rod 24 can be started to extend, the extension of the multi-section electric push rod 24 drives the moving sleeve rod 252 to move along the sliding groove 251 on the outer periphery of the fixed column 25, at the same time, the movement of the moving sleeve rod 252 also synchronously drives the connecting plate 26 on the outer periphery of the moving sleeve rod 252 to move;

[0058] The installation rod 261 is installed on both sides of the connecting plate 26, which pushes the connecting sleeve rod 262 to move, with the movement of the connecting sleeve rod 262, it further pushes the connecting rod 263 on both sides of the mounting plate 264, the pushing of the connecting rod 263 makes the arc plate 27 connected with the mounting plate 264 unfold, so as to tighten the loose copper wire;

[0059] At the same time, with the expansion of the arc-shaped plate 27, the mobile block 28 connected on one side will move in the moving groove 23, which can not only tighten the copper wire through the expansion of the arc-shaped plate 27, but also adjust the winding inner diameter of different sizes to ensure the tight winding of the copper wire.

[0060] As shown in Figure 1 、 Figure 3 、 Figure 5 、 Figure 6 The drawing box 11 is provided with a pressing assembly 30 on one side, which comprises a plurality of fixed blocks 31 fixedly connected on one side of the drawing box 11, a fixed rod 32 connected between every two fixed blocks 31, a lifting plate 33 slidingly connected on the outer periphery of the fixed rod 32, a telescopic spring 34 sleeved on the outer periphery of the fixed rod 32, a pressing piece connected on one side of the lifting plate 33 through an extension plate 35, the pressing piece comprising an L-shaped block 351 fixedly connected on the bottom of the extension plate 35, a sliding groove 352 formed in the inside of the L-shaped block 351, a sliding block 353 slidingly connected on the inner wall of the sliding groove 352, a resilient rubber sheet 354 connected on the bottom of the sliding block 353, a mounting hole 355 formed in the top of the L-shaped block 351 and the sliding block 353, and a mounting screw threadedly connected on the inner wall of the mounting hole 355, and a transmission piece connected on one side of the lifting plate 33, the transmission piece comprising an arc-shaped block 36 fixedly connected on the bottom of the lifting plate 33 and an arc plate 361 connected on one side of the mobile block 28, a plurality of abutting rods 362 connected on the outer periphery of the arc plate 361, and the abutting rods 362 abutting against the arc-shaped block 36.

[0061] In order to prevent the loosening of the copper wire, the following mechanism is designed: when the mobile block 28 moves in the moving groove 23, it will synchronously drive the arc plate 361 on one side to move, the movement of the arc plate 361 will in turn drive the plurality of abutting rods 362 on its outer periphery to move synchronously, with the movement of the abutting rods 362, they will abut against the lifting plate 33 connected with the arc-shaped block 36, so that it moves along the outer periphery of the fixed rod 32, in the process, the movement of the lifting plate 33 will produce a squeezing effect on the telescopic spring 34.

[0062] At the same time, the movement of the lifting plate 33 will also drive the extension plate 35 and the L-shaped block 351 connected thereto to move synchronously, this series of movements enable the arc-shaped plate 27 to expand, and through the abutting action of the abutting rods 362, it ensures that the resilient rubber sheet 354 driven by the L-shaped block 351 can always keep tightly pressing the copper wire, thereby effectively preventing the excessive loosening of the copper wire.

[0063] In addition, in order to adapt to different thickness of copper wire and effectively resist, the mechanism is also designed adjustable elastic rubber sheet 354, the specific operation is: first twist the mounting screw, make it separate from the L-shaped block 351 and the sliding block 353 installation hole 355, then can push the elastic rubber sheet 354, make it drive the sliding block 353 from the sliding groove 352, then can replace the different thickness of elastic rubber sheet 354, to adapt to and resist the copper wire of different thickness, such design greatly enhances the flexibility and practicability of the mechanism.

[0064] As shown in Figure 1 , Figure 7 , Figure 8 , the drawing box 11 side is equipped with adjusting assembly 40, adjusting assembly 40 includes the inclined surface 41 opened in the outer circumference of one of the lifting plate 33, the drawing box 11 side is fixedly connected with the welding block 42, the welding block 42 is slidably connected with the push block 422 in the inside through the elastic element, the elastic element includes the welding rod 421 connected in the inner wall of the welding block 42, the outer circumference of the welding rod 421 is sleeved with the compression spring 423, and the side of the push block 422 is connected with the inclined block 424 abutting against the inclined surface 41, the side of the inclined block 424 is connected with the adapter block 426 through the positioning rod 425, the adapter block 426 side is equipped with the push rod 427;

[0065] With the lifting plate 33 rises, the inclined surface 41 on the side will resist the inclined block 424, this action causes the push block 422 connected with the inclined block 424 to slide along the outer circumference of the welding rod 421, and in the process, the compression spring 423 is extruded, at the same time, the movement of the inclined block 424 also drives the positioning rod 425 to move, thereby making the positioning rod 425 abutting against the adapter block 426 to displace, the movement of the adapter block 426 also drives the push rod 427 connected with it, the push rod 427 immediately abuts against the copper wire, thereby increasing the tension of the copper wire, which effectively further prevents the copper wire from loosening.

[0066] As shown in Figure 1 , Figure 7 , Figure 8 , the inside of the adapter block 426 is equipped with cleaning assembly 50, the cleaning assembly 50 includes the slot 51 opened in the inside of the adapter block 426, and the inner wall of the slot 51 is fixedly connected with the adapter rod 52, the outer circumference of the adapter rod 52 is slidably connected with the lifting rod 53, the outer circumference of the adapter rod 52 is sleeved with the extrusion spring 54, the adapter block 426 and the outer circumference of the lifting rod 53 are equipped with the sponge cleaning sleeve 55;

[0067] In order to facilitate the cleaning of the oil stains on the outer periphery of the copper wire after drawing, the copper wire will be guided through the area between the push rod 427 and the lifting rod 53 after the drawing process is completed, and then the lifting rod 53 will slide and adjust on the outer periphery of the connecting rod 52 under the action of the pulling force of the compression spring 54. In this process, the push rod 427 and the sponge cleaning sleeve 55 equipped on the outer periphery of the lifting rod 53 will work together to effectively clean the oil stains on the outer periphery of the copper wire.

[0068] Working principle: In order to prevent the copper wire from loosening during the long-time winding process of the winding drum 16, when the copper wire shows signs of loosening, the multi-section electric push rod 24 will be immediately started to extend, which will drive the moving sleeve rod 252 to move smoothly along the sliding groove 251 on the outer periphery of the fixed column 25, and the movement of the moving sleeve rod 252 will also synchronously pull the connecting plate 26 on its outer periphery to move accordingly.

[0069] The connecting plate 26 is equipped with mounting rods 261 on both sides, which will push the connecting sleeve rod 262 to move, and with the continuous movement of the connecting sleeve rod 262, it will further push the connecting rods 263 on both sides of the mounting plate 264, and the pushing of these connecting rods 263 will eventually make the arc-shaped plate 27 connected by the mounting plate 264 slowly expand, thereby effectively tightening the loosened copper wire;

[0070] At the same time, the expansion of the arc-shaped plate 27 will also drive the moving block 28 connected on one side to move in the moving slot 23, which not only ensures that the arc-shaped plate 27 can be expanded in time for tightening according to the loosening of the copper wire, but also can be adjusted according to the inner diameter of the winding of different sizes, thereby maximizing the tight winding of the copper wire;

[0071] In order to further enhance the effect of preventing the copper wire from loosening, an additional tightening mechanism is designed, when the moving block 28 moves in the moving slot 23, it will synchronously drive the arc plate 361 on one side to move, the movement of the arc plate 361 will promote the synchronous movement of the several resistance rods 362 on its outer periphery, these resistance rods 362 will resist the lifting plate 33 connected with the arc-shaped block 36, making it move along the outer periphery of the fixed rod 32, in this process, the movement of the lifting plate 33 will produce a squeezing action on the extension spring 34, thereby increasing the stability of the system;

[0072] Meanwhile, the movement of the lifting plate 33 also drives the extension plate 35 and the L-shaped block 351 connected thereto to move synchronously, and this series of movements makes the arc-shaped plate 27 more stably expand, and through the abutting action of the abutting rod 362, it is ensured that the elastic rubber sheet 354 driven by the L-shaped block 351 can always keep close abutting pressure on the copper wire. In order to adapt to copper wires of different thicknesses and effectively abut tightly, adjustable elastic rubber sheets 354 are designed, and users can easily realize this adjustment by screwing the mounting screws and replacing elastic rubber sheets 354 of different thicknesses.

[0073] In addition, with the lifting of the lifting plate 33, the inclined surface 41 on one side will abut against the inclined block 424, causing the pushing block 422 connected to the inclined block 424 to slide along the outer periphery of the welding rod 421 and produce extrusion on the compression spring 423. At the same time, the movement of the inclined block 424 also drives the positioning rod 425 to move, thereby causing the positioning rod 425 to abut against the abutment block 426 to displace, and the movement of the abutment block 426 drives the pushing rod 427 connected thereto, which in turn abuts against the copper wire, thereby further increasing the tension of the copper wire, which effectively prevents the copper wire from loosening.

[0074] Finally, in order to facilitate the cleaning of oil stains on the outer periphery of the copper wire after wire drawing, a sponge cleaning sleeve 55 is arranged between the pushing rod 427 and the lifting rod 53, and the copper wire will be guided through this area after the wire drawing process is completed. Then, through the pulling force of the compression spring 54, the lifting rod 53 will slide and adjust on the outer periphery of the abutment rod 52, and in this process, the pushing rod 427 and the sponge cleaning sleeve 55 on the outer periphery of the lifting rod 53 will jointly act on the copper wire to effectively clean the oil stains on the outer periphery of the copper wire.

[0075] The above is only the preferred specific implementation of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art can make equivalent replacements or changes within the technical range disclosed by the present application according to the technical solution and inventive concept of the present application, which should be covered within the protection scope of the present application.
