Description

Technical Field

[0001] The present invention relates to a support and fixing device for card clothing processing, in particular to a feeding device for an irregular card clothing steel wire coil. Background Art

[0002] The general manufacturing process of ordinary metallic card clothing is that spheroidized steel wire is rolled into a blank bar by a high-speed rolling mill, and after recrystallization annealing, it is punched, quenched, and coiled into a product on a punching, quenching, and coiling production line; or the spheroidized steel wire is rolled into a blank bar by a high-speed rolling mill and directly punched, annealed online, quenched, and coiled into a product on a punching, quenching, and coiling production line. Among them, when the spheroidized steel wire is rolled into a blank bar with a certain standard shape and size by a high-speed rolling mill, the manufacturer first tightly winds the spheroidized steel wire into a hollow cylindrical shape and forms it by tying with flat iron bars for transportation. However, when leaving the factory, the cylindrical spheroidized steel wire coil is usually made into a finished product according to the standards of an outer diameter of 0.68 m, an inner diameter of 0.38 m, and a length of 0.275 m. Therefore, the spheroidized steel wire coil with a weight of about 400 kg formed in this way often deforms due to extrusion, collision, etc. during handling and transportation. The inner diameter of the deformed cylindrical spheroidized steel wire coil, that is, the middle hole, also deforms accordingly, so that the cylindrical spheroidized steel wire coil cannot be installed on the unwinding rack of the high-speed rolling mill because the roller shaft on the unwinding rack cannot be inserted into the middle hole of the deformed cylindrical spheroidized steel wire coil. If the product transported from the spheroidized steel wire coil manufacturer is deformed and cannot be installed on the unwinding rack, it has to be returned to the original manufacturer to be rewound and tied again, which undoubtedly increases the transportation, processing, and labor costs. Summary of the Invention

[0003] The purpose of the present invention is to overcome the deficiencies in the prior art and provide an irregular card clothing steel wire coil feeding device with a simple structure, convenient use, time and labor saving, and simple installation.

[0004] To achieve the above object, the present invention provides an irregular card clothing wire coil feeding device, which includes a feeding rack of a high-speed rolling mill. A roller is arranged on the feeding rack, and a circular outer disc cover that can be installed or disassembled is arranged at the outer end of the roller. A cylindrical rotating shaft is arranged in the middle of the roller, and the length of the cylindrical rotating shaft is equal to the width of the wire coil. The middle part of the outer disc cover is fixed to the outer end of the cylindrical rotating shaft by a plurality of bolts. Three bolt holes are arranged at equal angles at the outer end of the cylindrical rotating shaft, and three bolt through-holes are arranged at the positions of the outer disc cover corresponding to the three bolt holes on the cylindrical rotating shaft. Three screws with equal lengths are correspondingly arranged on the three bolt holes of the cylindrical rotating shaft. The inner end of each screw is provided with a rotating thread corresponding to the bolt hole, the outer end of the screw is provided with an external thread, and an active nut corresponding to the external thread is arranged at the outer end of the screw. A fixed nut is arranged between the rotating thread and the external thread of the screw. The outer diameter of the active nut is larger than the inner diameter of the bolt through-hole on the outer disc cover, and the diameter of the screw provided with the external thread is smaller than the diameter of the bolt through-hole on the outer disc cover. The length of the screw provided with the external thread is greater than the length of the wire coil.

[0005] A conical body for the wire coil to slide is arranged on the outer side of the fixed nut on the screw, and the included angle between the outer wall of the conical body and the central axis of the screw is 30° to 60°.

[0006] The beneficial effect of the present invention is that the irregular card clothing wire coil feeding device of the present invention has a simple structure and is easy to use. By installing three bolts at the outer end of the rotating shaft of the feeding rack turntable and using the outer disc cover, the deformed card clothing wire coil can be smoothly placed on the feeding rack, solving the problem that the deformed card clothing wire coil cannot be directly processed and needs to be sent back to the original factory for rework.

[0013] As Figure 1 , Figure 2 and Figure 3 shown, the irregular card clothing wire coil loading device of this embodiment includes a material discharging rack 1 of a high-speed rolling mill. A roller 2 is arranged on the material discharging rack 1. A circular outer disc cover 3 that can be installed or disassembled is arranged at the outer end of the roller 2. A cylindrical rotating shaft 4 is arranged in the middle of the roller 2. The length of the cylindrical rotating shaft 4 is equal to the length of the wire coil 5. The middle part of the outer disc cover 3 and the outer end of the cylindrical rotating shaft 4 are fixed by a plurality of bolts 6. Three bolt holes 7 are arranged at equal arcs at the outer end of the cylindrical rotating shaft 4. Three bolt through holes 8 are arranged at the positions of the outer disc cover 3 corresponding to the three bolt holes 7 on the cylindrical rotating shaft 4. Three screw rods 9 with equal lengths are correspondingly arranged on the three bolt holes 7 of the cylindrical rotating shaft 4.

[0014] As Figure 4 shown, a rotating thread 10 corresponding to the bolt hole 7 is arranged at the inner end of each screw rod 9. An external thread 11 is arranged at the outer end of the screw rod 9. An active nut 12 corresponding to the external thread 11 is arranged at the outer end of the screw rod 9. A fixed nut 13 is arranged between the rotating thread 10 and the external thread 11 of the screw rod 9. The outer diameter of the active nut 12 is larger than the inner diameter of the bolt through hole 7 on the outer disc cover 3. The diameter of the screw rod 9 provided with the external thread 11 is smaller than the diameter of the bolt through hole 8 on the outer disc cover 3. The length of the screw rod 9 provided with the external thread 11 is larger than the length of the wire coil 5. A conical body 14 for the wire coil 5 to slide is arranged on the outer side of the fixed nut 13 on the screw rod 9. The included angle between the outer wall of the conical body 14 and the central axis of the screw rod 9 is 30° to 60°.

[0015] Fix the rotating thread 10 end of the screw rod 9 into the bolt hole 7 on the cylindrical rotating shaft 4, and use a wrench to tighten the fixed nut 13 on the screw rod 9 so that the screw rod 9 is fixed to the cylindrical rotating shaft 4. After the three screw rods 9 are all fixed to the outer end of the cylindrical rotating shaft 4, the irregular wire coil 5 formed by being collided or extruded is sleeved onto the three screw rods 9 in the horizontal direction. Then, the external thread 11 ends of the three screw rods 9 are correspondingly passed through the three bolt through holes 8 on the outer disc cover 3, and then the active nut 12 is sleeved onto the outer end of the screw rod 9. Use a wrench to twist the active nuts 12 on the three screw rods 9 respectively and gradually so that the outer disc cover 3 slowly slides the wire coil 5 from the three screw rods 9 to the cylindrical rotating shaft 4. Among them, because the outer side of the fixed nut 13 on the screw rod 9 is the outer wall of the conical body 14 and the included angle between the outer wall of the conical body 14 and the central axis of the screw rod 9 is 60°, it is convenient for the wire coil 5 to move, that is, the resistance during movement is small. At the same time, when the irregular wire coil 5 is gradually extruded and moved from the screw rod 9 to the cylindrical rotating shaft 4 by the outer disc cover 3, the irregular wire coil 5 will automatically be sleeved onto the cylindrical rotating shaft 4, thus overcoming the drawback that the irregular wire coil 5 cannot be directly sleeved onto the cylindrical rotating shaft 4.

[0016] After the irregular wire coil 5 is completely sleeved onto the cylindrical rotating shaft 4, remove the outer disc cover 3 and then remove the three screw rods 9 from the cylindrical rotating shaft 4 as well; subsequently, the outer disc cover 3 can be fastened with six bolts 6, and thus the process of installing the irregular wire coil 5 onto the unwinding rack 1 is completed.
