[0008] The specific implementation of the present invention is further described below in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

When the unwinding of the entire coiled steel plate is completed, the coil changing action is performed; after the coil changing is completed, the splicing device splices the steel plates unwound successively from head to tail together; during splicing, the brake device locks the steel plate conveying at the front side of the buffer device, and the buffer device continues to supply the pre-buffered steel plate to the finished product production line; after the splicing is completed, the brake device releases the steel plate, the steel plate resumes normal transportation, and the buffer device restores the steel plate buffering amount to the predetermined buffering amount; When changing coils, the new coiled steel plate is put on the expansion and contraction shaft of the unwinding device, and then the hydraulic system is controlled to make the expansion and contraction shaft clamp the coiled steel plate, and then the head end of the steel plate is input into the splicing device; When unwinding the coiled steel plate, the motor of the unwinding device drives the expansion and contraction shaft to rotate, and the coiled steel plate rotates synchronously with the expansion and contraction shaft and unwinds; and the motor automatically adjusts the speed according to the vehicle speed requirements until the unwinding of the entire coiled steel plate is completed; and the coil thickness monitoring unit monitors the thickness of the coiled steel plate on the expansion and contraction shaft. When the thickness of the coiled steel plate is reduced to the preset lower limit, the alarm device is triggered to sound an alarm to remind the user to perform the coil change action; When the end of the first unrolled steel plate enters the splicing device, the steel plate end sensing unit senses the end of the steel plate, thereby triggering the splicing actuator to position the end of the steel plate at the splicing execution position, and triggering the brake device to perform the braking action; when the head end of the later unrolled steel plate enters the splicing device, the steel plate end sensing unit senses the head end of the steel plate, thereby triggering the splicing actuator to stack the head end of the steel plate with the previously positioned end of the steel plate to form a stacking section of two layers of steel plates; then the splicing actuator presses the stacking section to press out semi-annular upper convex parts and semi-annular lower concave parts alternately arranged along the width direction of the steel plate (the axes of the semi-annular upper convex parts and the semi-annular lower concave parts are parallel to the width direction of the steel plate), and the alternately arranged semi-annular upper convex parts and semi-annular lower concave parts form a slot extending along the width direction of the rolled steel plate and for the insertion of the insert strip; then the splicing actuator inserts the insert strip into the slot (such as Figure 1 As shown), the inserting strips are made to cross each semi-circular upper convex part and the semi-circular lower concave part, and the two ends of the inserting strips do not exceed the width of the rolled steel plate, so as to complete the splicing action (that is, the ends of the successively unrolled steel plates are spliced together); and when the splicing actuator completes the splicing action, the brake device is triggered to perform the unlocking action, and the cache device is triggered to perform the cache recovery action; When the brake device is triggered to perform the braking action, the clamping drive device drives a pair of clamping rollers to clamp the steel plate, locking the steel plate conveying on the front side of the buffer device; When the brake device locks the steel plate being transported forward, the buffer device will continue to supply the pre-stored steel plates to the finished product production line to avoid the finished product production line stopping due to lack of steel plates; When the brake device is triggered to perform the unlocking action, the clamping drive device drives a pair of clamping rollers to release the steel plate, and the steel plate resumes normal transportation; When the cache device is triggered to perform the cache recovery action, the cache device stores the steel plates until the cache amount of the steel plates reaches the predetermined cache amount (it takes about 3 minutes to put a new coil of steel plates on the expansion and contraction shaft each time. To ensure that the finished product production line does not stop, the cache device stores steel plates that can be used by the finished product production line for about 5 minutes).
[0010] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
