Description

Technical Field

[0001] The present invention relates to the technical field of copper coil processing, and particularly to a spiral forced conveying device for mill waste. Background Art

[0002] A rolling mill is a key industrial device that uses rotating rolls to apply pressure to metal or other materials to cause plastic deformation. It is mainly used to process metal billets into required shapes and sizes, such as plates, strips, profiles (such as I-beams, channel steels), bars, wires, and pipes, etc. Its core working principle is that through the relative movement and pressure action between the rolls, the material undergoes continuous compression and extension at high temperature (hot rolling) or normal temperature (cold rolling), thereby improving the internal structure of the material and enhancing its mechanical properties.

[0003] In the existing copper processing technology, the rolling mill mainly completes the leveling process of copper coil copper bars through a double extrusion shaft cold pressing process. By setting two extrusion shafts inside the rolling mill to extrude the copper coil copper bars, the leveling treatment of the copper coil copper bars is achieved. After leveling, a cutting device is used to remove the head and tail of the copper coil copper bars, and then in cooperation with a crushing device, the further recycling of the waste of the copper coil copper bars is realized. However, since the rolling mill of the existing technology only has the function of cold pressing and leveling, it is necessary to match an additional cutting device to cut the head and tail of the copper bar after cold pressing. After cutting, it is necessary to manually unload the cut waste and put it into the crushing device to realize the waste recycling function, resulting in the processing of copper coil copper bars by the rolling mill of the existing technology being time-consuming and laborious; In view of the above technical defects, a solution is proposed now.

[0018] Such as Figures 1-9As shown in the figure, a screw forced conveying device for rolling mill waste includes an equipment frame 1 and a crushing box 101. The crushing box 101 is fixedly installed on the inner wall of the equipment frame 1. A crushing shaft 102 is rotatably installed on the inner wall of the equipment frame 1. There are two crushing shafts 102 evenly distributed on the inner wall of the crushing box 101. One end of the two crushing shafts 102 extends from the inner wall of the crushing box 101 to its outer surface. A driving gear 103 is fixedly installed on the outer surface of the crushing shaft 102. The two crushing shafts 102 are meshed and driven with each other through the two driving gears 103 respectively. There are two driving gears 103 correspondingly distributed on the outer surfaces of the two crushing shafts 102. An inlet inclined plate 104 is arranged on the top surface of the crushing box 101. A screw conveyor shaft 105 is rotatably installed on the inner wall of the crushing box 101. One end of the screw conveyor shaft 105 extends from the inside of the crushing box 101 to its outside. The screw conveyor shaft 105 is meshed and driven with one of the driving gears 103 through a transmission gear 107. A discharge port 106 is arranged on one side surface of the crushing box 101. A transmission gear 107 is fixedly installed on the outer surface of the screw conveyor shaft 105. A leveling mechanism is installed on the inner wall of the equipment frame 1. A control mechanism is installed on one side surface of the equipment frame 1. The transmission assembly includes a driving gear 5. A chain 6 is installed on the outer surface of the driving gear 5. There are two driving gears 5. The two driving gears 5 are respectively fixedly installed on the outer surfaces of the extrusion shaft 402 and the crushing shaft 102. The two driving gears 5 are driven with each other through the chain 6.

[0019] In the embodiment of the present invention, when the extrusion shaft 402 rotates to level the copper coil, the crushing shaft 102 will synchronously rotate with the extrusion shaft 402. Because the crushing shaft 102 is meshed with the driving gear 103 installed on the surface of the other crushing shaft 102 through the driving gear 103, when one of the crushing shafts 102 and the driving gear 103 rotate, it will drive the other crushing shaft 102 and the driving gear 103 to rotate. At this time, when the copper coil that slides into the inside of the crushing box 101 contacts the two rotating crushing shafts 102, the rotating crushing shaft 102 will cut the copper coil through the crushing teeth on the surface, so as to cut the copper coil into strips, and finally fall out from the gap between the two crushing shafts 102 and fall onto the outer surface of the screw conveyor shaft 105.

[0020] Refer to Figures 1-9, Specifically, the control mechanism includes a flipping component and a cutting component. The flipping component includes a rotating groove 2 which is opened on both sides of the crushing box 101. The inner wall of the rotating groove 2 is rotatably installed with a flipping plate 201. The bottom surface of the flipping plate 201 is in movable contact with the inner wall of the equipment frame 1. Two contact shafts 202 are fixedly installed on both sides of the flipping plate 201. The outer surface of the contact shaft 202 is in movable contact with a control rod 203. There are two control rods 203, and one ends of the two control rods 203 are respectively fixedly connected to the ends of two electric telescopic rods 204. An electric telescopic rod 204 is installed on one side surface of the equipment frame 1, and two electric telescopic rods 204 are installed at equal intervals on one side surface of the equipment frame 1.

[0021] In the embodiment of the present invention, when the electric telescopic rod 204 is started, it will drive the control rod 203 to move downward. The inner wall of the control rod 203 is in movable contact with the outer surface of the contact shaft 202. When the control rod 203 moves downward, it will push the flipping plate 201 to rotate on the inner wall of the rotating groove 2 through the contact shaft 202. When the electric telescopic rod 204 is fully extended, at this time, the flipping plate 201 will complete a 40-degree rotation on the inner wall of the rotating groove 2, so that the crushing box 101 and the feeding inclined plate 104 are exposed, facilitating the subsequent collection and treatment of the copper coil waste.

[0022] Refer to Figures 1-9 , Specifically, the cutting component includes a second hydraulic rod 3 which is fixedly installed on one side surface of the equipment frame 1. The bottom surface of the second hydraulic rod 3 is fixedly installed with a guillotine knife 301. A limiting plate 302 is fixedly installed on one side surface of the equipment frame 1. The inner wall of the limiting plate 302 is in sliding contact with the outer surface of the guillotine knife 301. Two limiting plates 302 are installed at equal intervals on one side surface of the equipment frame 1. A transport frame 303 is installed on the top surface of the equipment frame 1. The inner wall of the transport frame 303 is rotatably installed with a roller 304. A number of rollers 304 are installed in a linear array on the inner wall of the transport frame 303. A meshing plate 305 is arranged on one side surface of the transport frame 303. The inner wall of the meshing plate 305 is in sliding contact with the flipping plate 201. A positioning shaft 306 is installed on the top surface of the equipment frame 1. Two positioning shafts 306 are installed at equal intervals on the top surface of the equipment frame 1. The inner walls of the two positioning shafts 306 are respectively in sliding connection with the outer sides of the two control rods 203.

[0023] In an embodiment of the present invention, when the copper coil needs to be cut, the two extrusion shafts 402 are rotated by a motor at this time. When the two extrusion shafts 402 rotate, they will push the copper coil forward. When the copper coil is continuously output, the end of the copper coil will enter the inner wall of the crushing box 101. When it is necessary to cut the damaged copper coil during transportation, the second hydraulic rod 3 is started at this time. When the second hydraulic rod 3 is started, it will drive the guillotine 301 installed at its end to move downward along the inner wall of the limit plate 302. When the guillotine 301 moves to the end along the limit plate 302, the bottom of the guillotine 301 will contact the top surface of the copper coil, and the copper coil will be cut by the extrusion force provided by the second hydraulic rod 3, realizing the removal of the damaged copper coil.

[0024] Referring to Figures 1-9 , specifically, the leveling mechanism includes an extrusion assembly and a transmission assembly. The extrusion assembly includes positioning blocks 4. The positioning blocks 4 are installed on the inner wall of the equipment frame 1. Four positioning blocks 4 are installed in a linear array on the inner wall of the equipment frame 1. A bearing 401 is correspondingly distributed on the inner wall of each positioning block 4. The bearing 401 is fixedly installed on the inner wall of the positioning block 4. An extrusion shaft 402 is rotatably installed on the inner wall of the bearing 401. There are two extrusion shafts 402, and each extrusion shaft 402 is rotatably connected to the inner walls of the two bearings 401. The top surface of the equipment frame 1 is provided with a first hydraulic rod 403. Four first hydraulic rods 403 are installed in a linear array on the top surface of the equipment frame 1. The end of each first hydraulic rod 403 extends from the top surface of the equipment frame 1 to its interior. The bottom surface of the first hydraulic rod 403 is fixedly installed with an adjustment plate 404. The top surface of the adjustment plate 404 is fixedly connected to the ends of the four first hydraulic rods 403. The bottom surface of the adjustment plate 404 is fixedly connected to the top surfaces of the two positioning blocks 4. The outer surfaces of two of the positioning blocks 4 are slidably connected to the inner wall of the equipment frame 1.

[0025] In an embodiment of the present invention, when the copper coil is located between the two extrusion shafts 402, the first hydraulic rod 403 is started at this time. When the first hydraulic rod 403 is started, its end will extend out, so as to drive the extrusion shaft 402 on the inner wall of the positioning block 4 to move downward through the adjustment plate 404. When the extrusion shaft 402 moves downward along the inner wall of the equipment frame 1, the extrusion shaft 402 will contact the outer surface of the copper coil at this time, and the copper coil will be extruded by the two extrusion shafts 402 to realize the fixation of the copper coil.

[0026] Specific usage process: When the rolling mill is needed, at this time, two universal shafts are respectively connected to one end of the two extrusion shafts 402, and the two universal shafts are connected to the inside of the speed reducer. Then, the motor provides power for the speed reducer, so that the speed reducer can drive the two extrusion shafts 402 to rotate. When the rolling mill is needed to process the copper coil, at this time, one end of the copper coil is fed into the inner walls of the two extrusion shafts 402, and the electric telescopic rod 204 is started at the same time. When the electric telescopic rod 204 is started, it will drive the control rod 203 to move downward. The inner wall of the control rod 203 is in movable contact with the outer surface of the contact shaft 202. Then, when the control rod 203 moves downward, it will push the turning plate 201 to rotate on the inner wall of the rotating groove 2 through the contact shaft 202. When the electric telescopic rod 204 is fully extended, at this time, the turning plate 201 will complete a 40-degree rotation on the inner wall of the rotating groove 2, so that the crushing box 101 and the feeding inclined plate 104 are exposed, facilitating the subsequent collection and treatment of copper coil waste. When the copper coil is located between the two extrusion shafts 402, at this time, the first hydraulic rod 403 is started. When the first hydraulic rod 403 is started, its end will extend, so as to drive the extrusion shaft 402 inside the positioning block 4 to move downward through the adjusting plate 404. When the extrusion shaft 402 moves downward along the inner wall of the equipment frame 1, at this time, the extrusion shaft 402 will contact the outer surface of the copper coil, and the copper coil will be fixed by the two extrusion shafts 402. When the copper coil needs to be cut, at this time, the two extrusion shafts 402 are driven to rotate by the motor. When the two extrusion shafts 402 rotate, they will push the copper coil forward. When the copper coil is continuously output, the end of the copper coil will enter the inner wall of the crushing box 101. When the damaged copper coil during transportation needs to be cut, at this time, the second hydraulic rod 3 is started. When the second hydraulic rod 3 is started, it will drive the knife gate 301 installed at its end to move downward along the inner wall of the limit plate 302. When the knife gate 301 moves to the end along the limit plate 302, at this time, the bottom of the knife gate 301 will contact the top surface of the copper coil, and the copper coil will be cut by the extrusion force provided by the second hydraulic rod 3, realizing the excision of the damaged copper coil.

[0027] When the damaged copper coil is cut off, the damaged copper coil will fall into the interior of the crushing box 101. Since the driving gear 5 is installed on the outer surface of the extrusion shaft 402, when the extrusion shaft 402 rotates, the driving gear 5 will drive another driving gear 5 to rotate through the chain 6, and the other driving gear 5 is installed on the outer surface of the crushing shaft 102. Therefore, when the extrusion shaft 402 rotates to level the copper coil, the crushing shaft 102 will rotate synchronously with the extrusion shaft 402. Because the driving gear 103 on the surface of the crushing shaft 102 meshes with the driving gear 103 installed on the surface of another crushing shaft 102, when one crushing shaft 102 and the driving gear 103 rotate, they will drive the other crushing shaft 102 and the driving gear 103 to rotate. At this time, when the copper coil that has slipped into the interior of the crushing box 101 contacts the two rotating crushing shafts 102, the rotating crushing shafts 102 will cut the copper coil through the crushing teeth on the surface, thereby cutting the copper coil into strips and finally falling out from the gap between the two crushing shafts 102 and falling onto the outer surface of the spiral conveying shaft 105. When the crushing shaft 102 rotates, it will drive the transmission gear 107 and the spiral conveying shaft 105 to rotate on the inner wall of the crushing box 101 through the driving gear 103. At this time, the rotating spiral conveying shaft 105 will use rotation to convey the strip-shaped copper coil falling on its surface to the inside of the discharge port 106 provided on one side surface of the crushing box 101, and finally convey the waste copper coil out of the inside of the discharge port 106 through rotation, realizing the forced conveyance of the copper coil.

[0028] When the damaged copper coil is completely cut, the electric telescopic rod 204 is started again at this time. The control rod 203 is driven to move upward through the electric telescopic rod 204, so that when the control rod 203 moves upward, the contact shaft 202 pulls the turning plate 201 to rotate on the inner wall of the rotation groove 2, and finally the turning plate 201 is in a horizontal state. At this time, the rotation of the extrusion shaft \alpha can be continuously controlled. When the two extrusion shafts 402 rotate, they level and convey the copper coil, so that the copper coil moves from the top surface of the turning plate 201 to the top surface of the roller 304, which is convenient for subsequent secondary processing of the copper coil. And because the width of the feeding inclined plate 104 of this equipment is greater than the width of the rolling mill, the waste generated in the subsequent processing of the copper coil can be put in from both sides of the crushing box 101, and the crushing shaft 102 crushes and recovers the waste.

[0029] The above are all the preferred embodiments of the present invention, and the protection scope of the present invention is not limited hereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
