Description

Technical Field

[0001] The invention relates to the technical field of coiled material splicing, in particular to a BLK tailings recycling process and equipment thereof. Background Art

[0002] The process of feeding the steel strip into the punching machine is roughly as follows: the steel strip is fed in sections according to a certain length. Since the unwinding mechanism of the coil must clamp a small section of the steel strip (this section of the steel strip can be punched again to form a product), a certain amount of tailings will remain after each feeding. When replacing a new coil, the tailings need to be removed. Therefore, the existing coil feeder cannot feed the coil tailings into the punching machine, resulting in a large waste. Summary of the invention

[0003] In view of the deficiencies of the prior art, the present invention provides a device which can feed the tailings into a punching machine so as to realize the utilization of the tailings.

[0004] The technical solution of the present invention is:

[0005] BLK tailings recycling process and equipment, which includes a punching machine, a front-end platform of a leveling machine, a leveling machine and a coil feeder, wherein the coil feeder feeds the coil into the punching machine after passing through the leveling machine and the front-end platform of the leveling machine, and is characterized in that a tailings welding machine is arranged on the front-end platform of the leveling machine.

[0006] Specifically, the tail material welding machine includes two symmetrical square tube supports, a first cross bar and a second cross bar are arranged between the two square tube supports, a pair of narrow steel strip rolls are installed on the first cross bar (different from the steel strip originally used for stamping, this is a roll of narrow and thin steel strip), and a lifting cylinder and a resistance welding are installed on the second cross bar. A suction cup is arranged at the end of the push rod of the lifting cylinder, and the front end of the narrow steel strip of the narrow steel strip roll extends out and is located below the resistance welding.

[0007] Two steel belt drive motors are fixed on the first cross bar corresponding to the two narrow steel belt rolls through brackets, and the rotating shafts of the steel belt drive motors are connected to the rotating drums of the narrow steel belt rolls, so that the narrow steel belt has the power to push the tail steel belt.

[0008] The narrow steel strip roll is provided with an encoder for sensing how long the narrow steel strip has extended.

[0009] Working principle:

[0010] 1) When the punching machine punches the normal coil, there will inevitably be a section of tail material left that falls onto the front platform of the leveling machine;

[0011] 2) The staff (users with conditions can use automation equipment to achieve control) controls the lifting cylinder to press down the suction cup to fix the tailings, and then controls the resistance welding to press down and weld. Since the narrow steel strip is located below the resistance welding, it is pressed to the top surface of the tailing by the resistance welding head and welded to the tailings by the resistance welding;

[0012] 3) The staff (users with conditions can use automation equipment to achieve control) controls the steel strip drive motor to drive the narrow steel strip to unwind. When unwinding, the narrow steel strip pushes the tail steel strip into the punching machine, and then the punching machine completes a punching to form a product, and the narrow steel strip is cut off;

[0013] 4) Control the steel strip drive motor to drive the narrow steel strip coil to pull the front end of the narrow steel strip back to under the resistance welding.

[0014] The beneficial effect of the present invention is that the tailings are fed into the punching machine through the thin steel belt, so that the tailings that should be discarded are fully utilized. BRIEF DESCRIPTION OF THE DRAWINGS
