[0076] When the coil is rolled to a suitable size, the clamping mechanism on the conveying frame 201 clamps the coils on both sides of the cutting groove 213, and then the cutting motor 211 and the cutting moving mechanism are started, driving the cutting seat 210 to move horizontally, so that the cutting saw blade 212 cuts the coils in the conveying area. After the cutting is completed, the clamping mechanism releases the clamping of the coil, and then the driving motor 103 continues to drive the winding shaft 102 to rotate, so that the end of the coil is rolled from the conveying frame 201 to the winding shaft 102;

[0077] When the end of the coil is rolled onto the coil of the reel 102, the tape sticking mechanism 3 starts to start, and the glue sticking assembly 303 and the automatic cutting knife 304 are lowered to the coil through the lifting module 302. The reel 102 is in continuous rotation, and the glue sticking assembly 303 sticks the tape to the end of the coil so that the end of the coil can be fixed on the coil itself. Then the tape is cut by the automatic cutting knife 304, and finally the lifting module 302 rises again to complete the sticking of the end of the coil.

[0078] After the coil is wound and the end is pasted, the cover mechanism is started, and the second cylinder 207 is started to drive the flip plate 208 to flip toward one side of the conveying frame 201, so that the shaft sleeve cover 209 is away from the winding side end of the winding shaft 102, so that the winding side end of the winding shaft 102 is completely opened, so that the unloading and conveying can be carried out;

[0079] When the coil is being unloaded and conveyed, the air-expanding bearing 114 is deflated, allowing the coil to detach from the winding shaft 102. Then the unloading component 5 is opened, and the unloading motor 502 is started. The unloading motor 502 drives the driving gear 505 to rotate. With the cooperation of the driving gear 505 and the rack 506, the entire unloading seat 501 is driven to move along the unloading track 503. At the same time, under the action of the U-shaped baffle 504, the coil is limited on the receiving component 4 of the unloading seat 501, and finally moved out of the winding shaft 102, completing the unloading and unloading. The coil is then taken out manually or by equipment.

[0080] The present invention can accurately guide and convey the coil, fix the front end, automatically reel, cut the end, fix the end, and convey the coil by means of the guide conveying and cutting mechanism 2, the paper tube-free winding mechanism 1, the tape sticking mechanism 3, the receiving assembly 4, and the discharging assembly 5. The whole process is automated, no manual operation is required, and the efficiency is high.

[0081] And adopt a special air expansion shaft structure, by providing a cavity 112 and an insertion groove 113 connected to the cavity 112 in the winding shaft 102, and providing a C-shaped card plate in the cavity 112, and a flip driving device is provided between the C-shaped card plate and the winding shaft 102, so that the front end of the coil can be inserted into the insertion groove 113, and then the flip driving device drives the C-shaped card plate to rotate, so that the C-shaped card plate closes the notch of the insertion groove 113 and clamps the front end of the coil located in the insertion groove 113, so as to achieve the clamping and fixing of the coil, and there is no need to fix the coil by paper tube and tape (glue) as in the existing air expansion shaft, and the whole process of fixing the front end of the coil is automatic fixing, without manual operation, and the fixing process is short in time and high in efficiency, which can effectively improve the overall winding efficiency and is suitable for the existing fully automated production process. At the same time, the structure of the overall air expansion shaft is relatively simple and the cost is relatively low.

[0082] At the same time, the air expansion shaft of the present invention is also provided with a hand wheel 107, and the angle of the air expansion shaft can be adjusted by the hand wheel 107, so that manual adjustment is convenient when the insertion groove 113 is not aligned with the front end of the coil and for later maintenance.

[0083] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
