The invention has the following beneficial effects:
1. According to the invention, when steel coil processing equipment needs to process steel coils, the pulling equipment stops pulling the steel coils, the unreeling roller drives the steel coils to continuously unreel, at the moment, the tensioning roller II descends along the supporting plate to tightly press the steel coils against each other, so that the steel coils are always in a tensioning state, meanwhile, the lifting driving assembly drives the worm to descend and separate from the worm wheel, so that the worm wheel and the unreeling roller are not driven to rotate when the worm rotates, the unreeling roller stops unreeling, the tensioning roller II, the lifting driving assembly, the worm and the worm wheel are matched, so that the steel coils can be always in the tensioning state in a gap for stopping unreeling and processing, the steel coils are processed by the processing equipment conveniently, meanwhile, the rotary driving assembly is disconnected with the unreeling roller, so that a motor in the rotary driving assembly is not required to be stopped, the problems of overheating, current impact, abrasion and the like of the motor caused by frequent starting and stopping of the motor are prevented, and the service life of the motor is prolonged.
2. According to the invention, when the lifting driving assembly drives the worm to move downwards and separate from the worm wheel, the friction strip can be driven to move downwards synchronously, so that the friction strip is abutted against the friction wheel at the end part of the unreeling roller, the unreeling roller is locked through friction resistance between the friction strip and the friction wheel, the unreeling roller is prevented from driving the steel coil to continue to rotate under the action of rotation inertia, so that the steel coil is in a tensioning state when the steel coil is processed, meanwhile, due to the fact that the unreeling roller is in the locking state, when the follow-up steel coil processing is completed, the pulling equipment continues to pull the steel coil to move and convey, the steel coil can be tensioned first, so that the tensioned steel coil pushes the tensioning roller upwards to restore to an initial state, and meanwhile, the lifting driving assembly drives the worm to move upwards and be in meshed transmission connection with the worm wheel under the driving of the tensioning roller at the upper part, so that the steel coil is prevented from being automatically restored to the unreeling state when the steel coil is pulled through locking cooperation of the friction strip and the friction wheel.

Further, a connecting seat 515 is fixedly installed on the top surface of one side of the adjusting bracket 54, a friction strip 516 positioned on the outer ring of the top surface of the unreeling roller 41 is fixedly installed on the top end of the connecting seat 515, and a friction wheel 517 positioned below the friction strip 516 is fixedly installed on the unreeling roller 41; the inner ring of the friction strip 516 and the outer ring of the friction wheel 517 are both provided with friction lines, when the adjusting bracket 54 is in a high-position state, the friction strip 516 and the friction wheel 517 are in a separated state when the coil of steel 41 is rotationally unwound, and when the adjusting bracket 54 descends to break the transmission connection of the coil of steel 41, the adjusting bracket 54 drives the friction strip 516 to synchronously descend, so that the friction strip 516 abuts against the outer ring of the friction wheel 517, the coil of steel 41 is locked by friction fit between the friction strip 516 and the friction wheel 517, the coil of steel 41 is prevented from being driven to rotate under the action of rotational inertia so as to ensure that the coil of steel is continuously unwound in a tensioning state, meanwhile, the coil of steel 41 is in a locking state, so that the subsequent processing is completed, when the pulling equipment continues to pull and move and convey the coil of steel, the tensioned coil of steel can be tensioned firstly, the tensioning roller II 62 moves upwards, and returns to an initial state, and simultaneously the lifting driving assembly drives the worm 52 to be in meshed transmission connection with the upper end 51 under the driving of the tensioning roller II 62 so as to continuously drive the coil of steel 41 to rotate under the friction fit of the friction strip 517, so that the coil of steel 41 is automatically unwound and the coil of steel is ensured to be subjected to a locked state when the coil of steel is unwound under the pulling fit of the pulling condition.
Further, the worm wheel 51 is rotatably mounted on the unreeling roller 41, one side of the worm wheel 51 is provided with a buffer disc 522 fixedly mounted on the unreeling roller 41, the buffer disc 522 is provided with a plurality of grooves 523 communicated with the back surface of the worm wheel 51, the back surface of the worm wheel 51 is fixedly provided with buffer baffles 525 extending into the grooves 523, buffer springs 524 abutting against the buffer disc 522 and the buffer baffles 525 are mounted in the grooves 523, when the worm wheel 51 is in meshed transmission connection with the worm 52, the worm wheel 51 can drive the buffer disc 522 and the unreeling roller 41 to rotate after being subjected to expansion buffering of the buffer springs 524 when the worm wheel 52 drives the worm wheel 51 to rotate, friction force between the worm 52 and the worm wheel 51 can be reduced by buffering the worm 52 and the worm wheel 51 during meshing, and friction damage of the worm 52 and the worm wheel 51 is prevented.
Example five
Referring to fig. 1-10, the embodiment also discloses a feeding and unreeling method for steel coil, which comprises the following specific steps:
firstly, after one end of a steel coil arranged on an unreeling roller 41 passes through a tensioning roller II 62, a tensioning roller I61 and steel coil processing equipment, the end of the steel coil is communicated with pulling equipment, when the steel coil is processed, the steel coil is pulled by the pulling equipment, and meanwhile, a rotary driving assembly drives the unreeling roller 41 and the steel coil to rotate through the transmission of a worm 52 and a worm wheel 51 so as to enable the steel coil to be gradually unreeled, so that the steel coil is tensioned under the action of the pulling equipment and the unreeled steel coil processing equipment and gradually moves through the steel coil processing equipment;
When steel coil processing equipment needs to process steel coils, pulling equipment stops pulling the steel coils, the unreeling roller 41 drives the steel coils to continuously unreel, at the moment, the tensioning roller II 62 descends along the supporting plate 63 to tightly press the steel coils in an abutting mode so that the steel coils are always in a tensioning state, meanwhile, the lifting driving assembly drives the worm 52 to descend and separate from the worm wheel 51, so that the worm wheel 51 and the unreeling roller 41 are not driven to rotate when the worm 52 rotates, and the unreeling roller 41 stops unreeling;
When the steel coil processing is completed, the pulling device continues to pull the steel coil to move for the next steel coil processing, the tensioning roller II 62 is reset upwards under the support of the tightened steel coil, and meanwhile, the driving assembly drives the worm 52 to be in meshed transmission connection with the worm wheel 51, so that the rotary driving assembly can continue to drive the unreeling roller 41 and the steel coil to rotate, and the steel coil is continuously conveyed and unreeled.
