[0002] Shoelaces are a kind of belt that is used to tie the inner and outer uppers of shoes, decorate the uppers, adjust the tightness of shoes, ensure the safety of ankles, etc. After the shoelaces are produced, the shoelace heads need to be curled.

[0003] In a shoelace head processing mold with the authorization announcement number "CN214442351U", the mold is designed to directly cut the thin plate, and the thin plate is formed by single-sided cutting. Compared with the traditional one-time stamping, it avoids the generation of waste between the thin plates and saves material costs. The thin plate is cut on one side and only produces single-sided burrs, which reduces the generation of burrs compared with single-time stamping. However, when the device curls the shoelaces, it lacks straightening and fixing of the shoelaces, which can easily cause displacement of the shoelaces during curling, resulting in curling failure. At the same time, the curling mold needs to be lifted after the shoelace heads are curled to avoid affecting the subsequent curling of the shoelace heads, which reduces the working quality of the device.

[0024] Working principle:

[0025] Auxiliary fixing process of shoelace head curling:

[0026] The operator places three shoelaces inside the grooves on the surface of the mold 11, and at the same time places the two ends of the shoelaces on the surface of the second clamping block 206, connects the external power supply of the first motor 201, starts the output shaft of the first motor 201 to rotate and drive the threaded rod 203 to rotate, the threaded rod 203 rotates and drives the threaded block 204 to move downward, the threaded block 204 drives the first clamping block 205 to move synchronously, the first clamping block 205 moves downward to press against the surface of the shoelace to fix the shoelace, connects the external power supply of the third motor 5, starts the output shaft of the third motor 5 to rotate and drives the stud 6 to rotate, the stud 6 drives the support blocks 7 on both sides to move away from each other, so that the shoelace is tightened, which is convenient for subsequent processing and curling of the shoelace.

[0027] Auxiliary curling process of shoelace head curling:

[0028] The external power supply of the second motor 301 is turned on, and the output shaft of the second motor 301 is started to rotate to drive the roller 303 to rotate. The rotation of the roller 303 drives the slider 304 to move. The slider 304 drives the support plate 305 and the third shell 8 to move synchronously. When the mold 11 on the surface of the third shell 8 and the mold 11 on the surface of the box body 1 are tightly pressed, the output shaft of the second motor 301 is stopped from rotating, and the external power supply of the heating wire inside the mold 11 is turned on to energize the heating wire. The heat generated by the heating wire is transferred to the surface of the shoelaces through the mold 11, and the surface of the shoelaces is heated and baked. After the surface of the shoelace is heated and baked to form, the external power supply of the hydraulic cylinder 9 is turned on, the telescopic end of the hydraulic cylinder 9 is started to extend to drive the cutting knife 10 to move downward, and the cutting knife 10 punches and cuts the heated shoelaces.
