DETAILED DESCRIPTION

[0033] 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.

[0034] See also Figure 1-Figure 9The present invention provides a technical solution: a relaxation feeding device for a cable drawing machine, comprising a connecting frame 1, a fixed pad 12 arranged on the outside of the connecting frame 1, the connecting frame 1 is in a continuous bending shape, a mounting groove 11 is opened at one end of the connecting frame 1, and is used to be installed on one side of the drawing machine, the fixed pad 12 is rectangular, the fixed pad 12 is located on a side away from the mounting groove 11, and a circular groove is opened on the fixed pad 12 and the connecting frame 1, and a wire feeding mechanism 2 is clamped inside the circular groove;

[0035] A plurality of positioning shafts 13 are installed on the inner wall of the connecting frame 1 close to the fixed pad 12. The positioning shafts 13 are arranged in a uniform array on the outside of the circular groove. A limiting ring 14 is installed at one end of the plurality of positioning shafts 13. A transmission mechanism 3 is clamped inside the limiting ring 14. The transmission mechanism 3 is used for auxiliary transmission and cleaning of the copper wire. A conductor rack 4 is provided on one side of the transmission mechanism 3. When the wire needs to be drawn, auxiliary limiting can be performed under the action of the wire feeding mechanism 2. When one end of the wire is clamped inside the wire drawing machine, the wire can be transmitted and moved inside the equipment. The transmission mechanism 3 and the conductor rack 4 can be used to stretch and correct the limiting to prevent the surface from being bent. In addition, the surface of the wire can be cleaned during the transmission process to prevent debris or metal wire from being wrapped around the surface of the wire and causing it to be clamped on the surface of the wire during the drawing process.

[0036] like Figure 3 As shown, during the wire drawing process, dirt will inevitably adhere to the wire and needs to be cleaned. The wire feeding mechanism 2 includes a clamping ring 21 and a tapered tube 23. The clamping ring 21 is clamped inside the circular groove, and the tapered tube 23 is installed inside the clamping ring 21. A swing ring 25 is installed at one end of the tapered tube 23.

[0037] A plurality of cleaning grooves 251 are provided on the inner wall of the swing ring 25. The cleaning grooves 251 are arranged in a uniform array inside the swing ring 25. A plurality of friction plates are arranged inside the cleaning grooves 251. The friction plates inside the swing ring 25 and the wire are vertically staggered, which can effectively grind and clean the limiting surface to prevent dirt and the like from remaining on the wire and affecting the processing quality of the equipment.

[0038] like Figure 4 As shown, in order to ensure the cleaning effect of dirt on the wire surface, a plurality of squeezing balls are installed on the outer wall of the clamping ring 21, and a positioning ring 22 is clamped on the outer side of the squeezing balls. A plurality of transmission shafts 24 are installed at one end of the positioning ring 22. A plurality of straight grooves are opened on the clamping ring 21. The transmission shaft 24 passes through the straight grooves and rests on one end of the swing ring 25. During the transmission of the wire, it can be squeezed between the positioning ring 22, and the squeezing balls can be deformed by external force during the transmission process, so that the transmission shaft 24 can move and the swing ring 25 at one end can be moved. While further ensuring the cleaning effect of the equipment, the debris and impurities accumulated inside the cleaning groove 251 can also be quickly shaken off, which can effectively extend the maintenance cycle of the equipment and reduce the impact on the pretreatment of the wire.

[0039] like Figure 5 As shown, during the transmission process, the surface of the wire may be partially bumped due to external factors such as transportation, resulting in bending of the wire. The transmission mechanism 3 includes a positioning tube 31, a transmission ring 33 and multiple transmission tubes 35. The positioning tube 31 is clamped inside the limit ring 14. Multiple positioning pieces 34 are installed on the surface of the positioning tube 31. Multiple ring grooves are opened on the side wall of the positioning tube 31. A control motor 32 is installed at one end of the positioning tube 31. The transmission ring 33 is rotatably arranged on one side of the positioning tube 31. The control motor 32 is used to control the rotation speed of the transmission ring 33. With the help of the control motor 32, the transmission tube 35 can follow the transmission ring 33 to make a circular motion, and the wire can be stretched during the transmission process. The rotation speed of the transmission ring 33 can be controlled according to the material of the wire, which can ensure the correction effect of the equipment, facilitate the subsequent wire drawing process, and avoid the subsequent wire being twisted and broken due to stress.

[0040] The transmission tube 35 has a "C"-shaped cross-section and is elastic. A connecting shaft is installed at one end of the transmission tube 35, and the connecting shaft is clamped on the inner wall of the transmission tube 35. The transmission tube 35 is used for auxiliary stretching transmission of the wire. The elasticity of the transmission tube 35 itself can also prevent the two ends of the wire from being broken due to excessive stress during the correction process.

[0041] like Figure 6 As shown, in order to ensure stability during the correction process, a plurality of buffer balls 351 are fixedly connected between the transmission tubes 35. The positions of the buffer balls 351 correspond to the annular grooves. The top ends of the buffer balls 351 abut against the inner walls of the positioning pieces 34. The buffer balls 351 can be squeezed between the positioning pieces 34, thereby making the transmission tubes 35 movable and deformed during the circular motion, and being able to shake off excess debris inside the dust collection tubes 36 and the transmission tubes 35.

[0042] like Figure 7 As shown, in order to reduce the situation where metal wires are stuck on the surface of the wire or metal debris is stuck inside the wire, resulting in gaps on the edge, a dust suction pipe 36 is inserted into the transmission pipe 35, and a friction plate is provided on the inner wall of the dust suction pipe 36. A fixing ring 37 is installed at one end of the dust suction pipe 36, and a pair of reset shafts 371 are installed at one end of the fixing ring 37. The reset shafts 371 are connected to one side of the transmission pipe 35.

[0043] A plurality of arc grooves are provided on the vacuum tube 36, and a mesh plate 361 is installed inside the arc groove. The mesh plate 361 is arranged in a uniform array on one side of the outer wall of the vacuum tube 36. As the transmission tube 35 rotates, the friction plate inside the vacuum tube 36 can always clean and polish the wire 360 ​​degrees, and can clean and maintain metal chips stuck on the edge, thereby avoiding the situation where metal chips are embedded in the surface of the wire during the subsequent wire drawing process.

[0044] like Figure 8As shown, in order to reduce the situation where there are burrs and other residues on the surface of the wire, a plurality of support frames 42 are installed at one end of the wire rack 4, and a fixing frame 41 is installed at one end of the plurality of support frames 42. The fixing frame 41 is clamped at one end of the positioning tube 31. The wire rack 4 is funnel-shaped, and a plurality of positioning frames 45 are installed at one end of the wire rack 4. A reset ring 43 is installed on the outer wall of the positioning frame 45, and a plurality of friction plates 44 are arranged inside the reset ring 43. The friction plate 44 is used for auxiliary limiting during wire transmission. The wire passes through the support ring inside the wire rack 4, and during the transmission process, the limiting surface can be polished and cleaned with the help of the friction plate 44, and the excess burrs and protrusions on the surface of the wire can be cleaned, so as to facilitate the subsequent wire drawing process.

[0045] In order to ensure the stability of subsequent incoming wires, a support ring is installed inside the wire rack 4, and the support ring is used for wire transmission positioning. An internal thread is provided on the inner wall of the wire rack 4, and the inner diameter of the support ring can be adjusted according to actual conditions. The support ring can play an auxiliary limiting role to avoid wire deviation during transmission, thereby ensuring the stability of equipment processing.

[0046] Working principle: First, when the wire needs to be drawn, auxiliary limiting can be performed under the action of the wire feeding mechanism 2, and when one end of the wire is stuck inside the wire drawing machine, the wire can be transmitted and moved inside the equipment, and the transmission mechanism 3 and the wire rack 4 can be stretched and corrected to prevent the surface from being bent. In addition, during the transmission process, the surface of the wire can be cleaned to prevent debris or metal wire from being entangled on the surface of the wire and causing it to be stuck on the surface of the wire during the drawing process. In addition, during the transmission process of the wire, it can be squeezed against the inner wall of the positioning ring 22, and the transmission shaft 24 can drive the swing ring 25 to move, so that the wire rubs against the inner wall of the swing ring 25 during the transmission process, and the dirt adhering to the surface can be quickly cleaned;

[0047] Then, during the wire transmission process, the control motor 32 can drive the transmission ring 33 to rotate, and the transmission tube 35 can drive the wire to make a circular motion, so that the wire can be quickly stretched and corrected during the transmission process, and the bending and deviation of the wire surface can be effectively reduced. The rotation speed of the transmission ring 33 can be controlled according to the wires of different materials, and the wires of different materials can be corrected to ensure the processing quality of the equipment and prevent the wires from being deviated or even broken during the wire drawing process. During the circular motion of the wire, the buffer ball 351 can squeeze and rub against the positioning plate 34, thereby pushing the transmission tube 35 to deform slightly, and the internal dust suction tube 36 can also be deformed by force, so that the wire in the transmission process can be cleaned and polished with the help of the friction plate inside the dust suction tube 36, and the debris and metal wire adhering to the surface can be cleaned;

[0048] Finally, during the transmission process, the wire can pass through the support ring inside the wire rack 4, and during the transmission process, the limiting surface can be polished and cleaned with the help of the friction plate 44, and the excess burrs and protrusions on the wire surface can be cleaned to facilitate subsequent wire drawing processing.

[0049] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
