[0002] Copper is an important and irreplaceable raw material in economic development and has been widely used in various fields such as military industry, electric power, electronics and electrical engineering, communications, construction, light industry, machinery manufacturing and transportation. In recent years, the copper wire processing industry has developed rapidly. Copper wire drawing machine is a commonly used equipment in the copper wire processing process. The pay-off device used in conjunction with the copper wire drawing machine has an important influence on the effect of copper wire drawing. When in use, the motor drives the pay-off drum to rotate, and the copper wire is separated from the winding state on the pay-off drum as the pay-off drum rotates, and is transmitted to the drawing die box through the guide wheel for drawing.

[0003] However, there are some problems with the existing technology: since the height position of the guide wheel is fixed, when the copper wires wound on the pay-off drum at different heights are transported to the guide wheel, due to the height difference, the copper wires are easily rubbed against the edge of the guide wheel, resulting in wear and tear, which may cause the copper wire to break. Therefore, we propose a copper wire pay-off device and a wire drawing machine. Utility Model Content

[0004] In response to the problems existing in the prior art, the purpose of the present utility model is to provide a copper wire pay-off device and a wire drawing machine.

DETAILED DESCRIPTION

[0021] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0022] like Figures 1 to 5 As shown, a copper wire pay-off device and a wire drawing machine provided by an embodiment of the present invention include a base 1, a brake motor 2 is fixedly installed on the left side of the bottom of the base 1, the output shaft of the brake motor 2 is fixedly sleeved with a rotating shaft 3, the top of the rotating shaft 3 extends to the top of the base 1 and is fixedly connected to a disc 4, a pay-off drum body 5 is fixedly installed on the top of the disc 4, a frame 6 located to the right of the disc 4 is fixedly installed on the base 1, a cross bar 7 is provided inside the frame 6, and the cross bar 7 and the frame 6 are connected by a lifting mechanism, a pulley 8 located on the right side of the frame 6 is rotatably connected to the base 1, a guide wheel body 18 located between the frame 6 and the pulley 8 is provided on the base 1, and the guide wheel body 18 and the base 1 are connected by a buffer assembly.

[0023] When paying out the wire, the staff passes the copper wire wrapped on the pay-off drum body 5 between the two cross bars 7, and then draws it around the outer surface of the guide wheel body 18 and the pulley 8. When the copper wire is transferred from the pay-off drum body 5 to the guide wheel body 18, the staff can use the lifting mechanism to make the cross bar 7 slowly drive the copper wire to move up and down, so that the copper wire located at different heights on the pay-off drum body 5 can be smoothly transferred to the guide wheel body 18, avoiding the copper wire being worn and broken by the edge of the guide wheel body 18.

[0024] Furthermore, the lifting mechanism includes a drive motor 9, which is fixedly mounted on the frame 6. The output shaft of the drive motor 9 is fixedly sleeved with a bidirectional screw rod 10, and both sides of the outer surface of the bidirectional screw rod 10 are threadedly sleeved with sliders 11.

[0025] Furthermore, a mounting bracket 12 is movably mounted on the inner wall of the frame 6 , the crossbar 7 is rotatably connected to the mounting bracket 12 , and a connecting rod 13 is hinged between the mounting bracket 12 and the slider 11 .

[0026] By starting the drive motor 9, the bidirectional screw rod 10 can be rotated, so that the two sliders 11 can move toward or away from each other, and then the mounting frame 12 can be driven to move upward or downward through the connecting rod 13, so that the copper wire between the two cross bars 7 can be guided, so that when the copper wire wound at different heights on the pay-off drum body 5 is transmitted to the guide wheel body 18, the height difference between the copper wire and the guide wheel body 18 is reduced after passing through the cross bar 7, thereby reducing the friction loss between the copper wire and the edge of the guide wheel body 18.

[0027] Furthermore, the buffer assembly includes a vertical plate 14, which is fixedly mounted on the base 1. A round rod 15 is movably inserted into the vertical plate 14, and the rear end of the round rod 15 is fixedly connected to a mounting frame 17. The guide wheel body 18 is rotatably connected to the mounting frame 17.

[0028] Furthermore, a spring 16 is movably sleeved on the outer surface of the round rod 15 , and two ends of the spring 16 are fixedly connected to the installation frame 17 and the vertical plate 14 respectively.

[0029] By passing the copper wire around the guide wheel body 18 and the pulley 8, the spring 16 is compressed, and then the wire is drawn, the copper wire can be placed in a tensioned state. At the same time, due to the elastic force of the spring 16, it can act as a buffer for the copper wire when the wire is released, preventing the copper wire from breaking or becoming too loose and detaching from the guide wheel body 18 and the pulley 8.

[0030] Furthermore, a vertical rod 21 located between the disc 4 and the frame 6 is rotatably connected to the base 1 . There are two vertical rods 21 , and the two vertical rods 21 are symmetrically arranged.

[0031] A wire drawing machine includes a copper wire pay-off device, a wire drawing die box 19 and a winding mechanism 20. The wire drawing die box 19 is fixedly installed in the middle of the top of the base 1, and the winding mechanism 20 is fixedly installed on the right side of the top of the base 1.

[0032] The working principle and use process of this utility model:

[0033] When in use, the staff connects the copper wire from the pay-off drum body 5 to the winding mechanism 20, as shown in FIG. Figure 3As shown, the wire drawing operation is then performed. When paying out the wire, the staff starts the brake motor 2, so that the rotating shaft 3 drives the disc 4 and the wire-drawing drum body 5 to rotate, and the copper wire wound on the wire-drawing drum body 5 is transmitted to the guide wheel body 18 between the two vertical rods 21 and the two cross rods 7. The staff can start the driving motor 9 to make the bidirectional screw rod 10 rotate, so that the two sliders 11 can move toward or away from each other, and then the mounting frame 12 can be driven upward or downward by the connecting rod 13, so that the copper wire between the two cross rods 7 can be guided. When the copper wire wound on the wire-drawing drum body 5 at different heights is transmitted to the guide wheel body 18, the height difference between the copper wire and the guide wheel body 18 is reduced after passing through the cross rod 7, thereby reducing the friction loss between the copper wire and the edge of the guide wheel body 18, avoiding wear and breakage of the copper wire. At the same time, due to the elastic force of the spring 16, it can buffer the copper wire when paying out, avoiding the copper wire from being too tight and breaking or too loose and causing it to detach from the guide wheel body 18 and the pulley 8.

[0034] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
