[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] As Figures 1 to 6 shown, a punching machine for sponge processing includes a support frame 1. The multiple holes 101 on the inner surface of the support frame 1 facilitate the punching operation of the punching machine. The support legs 2 fixed to the bottom surface of the support frame 1 support the punching machine. The driving assembly 3 inside the support frame 1 sets the first turntable group 301, the second turntable group 302, and the third turntable group 303 to cooperate with each other to drive the feeding roller 4, the auxiliary roller 5, and the discharging roller 6 fixed on one side of it to work. The first rotating rod 401 and the second rotating rod 601 located inside the feeding roller 4 and the discharging roller 6 are provided with limiting members 404 to limit the two. The sponge is flattened by the flattening roller 7 located on one side of the auxiliary roller 5. The punching assembly 8 above one side of the flattening roller 7 is provided with an electric push rod 801 to push the shifting plate 802 up and down, so that the multiple punching heads 803 on the bottom surface of the shifting plate 802 correspond to the holes 101 one by one for punching. The protection assembly 9 on the surface of the punching head 803 is provided with a protection cover 903 to slide on the surface of the shifting plate 802 through the straight groove 904 to protect the punching head 803.

[0030] All three turntable groups are provided with a first turntable 311 and a second turntable 312, and the two are connected by a belt 313.

[0031] Through the above technical solution, under the connection of the belt 313, the first turntable 311 can drive the second turntable 312 to rotate together, so as to drive the feeding roller 4, the discharging roller 6, and the auxiliary roller 5 to rotate in the same direction.

[0032] Both ends of the flattening roller 7 rotate on the surface of the slider 701, and the slider 701 slides inside the fixed block 702 fixed on the surface of the support frame 1.

[0033] Through the above technical solution, under the action of gravity, the flattening roller 7 can be attached to the sponge surface through the slider 701, so that the flattening roller 7 can flatten the sponge passing under it.

[0034] A second spring 902 is arranged on the upper end surface of the protective cover 903 and is connected to the fixed cylinder 901 on the upper surface of the moving plate 802.

[0035] Through the above technical solution, under the elastic force of the second spring 902, the punching head 803 can be retracted inside the fixed cylinder 901 during the downward punching process to avoid affecting punching, and after the punching head 803 completes punching and rises, the protective cover 903 can automatically fall to protect the punching head 803.

[0036] A snap component 403 is arranged on the surface of the fixing ring 402 fixed on the inner side of the turntable two 312, where the surface of the first rotating rod 401 and the second rotating rod 601 are fixed.

[0037] Through the above technical solution, when the turntable two 312 rotates, the fixing ring 402 can rotate in cooperation with it, and the first rotating rod 401 and the second rotating rod 601 are driven to rotate through the snap component 403.

[0038] The snap component 403 is provided with a moving rod 431 with one end inserted on the surface of the first rotating rod 401, and the spring one 433 fixed between it and the fixing ring 402 is cooperated through the stopper 432 on its surface.

[0039] Through the above technical solution, under the elastic force of the spring one 433, the moving rod 431 can be clamped on the surface of the first rotating rod 401, and the first rotating rod 401 is driven to rotate as the fixing ring 402 rotates.

[0040] In use, when the user uses the punching machine for sponge processing, remove the limiting member 404 at one end of the first rotating rod 401, and pull the moving rod 431 so that one end of the moving rod 431 can be disengaged from the groove of the first rotating rod 401. Remove the feeding roller 4 through the first rotating rod 401, wind the sponge to be punched around the surface of the feeding roller 4. The driving assembly 3 is driven by a motor (not shown in the figure) so that the feeding roller 4 can rotate, and the sponge can pass under the auxiliary roller 5 and the flattening roller 7 and be placed on the inner surface of the support frame 1. Under the action of gravity, the slider 701 can slide inside the fixed block 702, and the sponge is flattened by the flattening roller 7. When passing under the punching assembly 8, the electric push rod 801 is used to push the moving plate 802 downward so that the punching head 803 can pierce the sponge and cooperate with the hole 101 for punching. The protective cover 903 outside the punching head 803 contracts into the fixed cylinder 901 under the elastic force of the second spring 902 during punching, and after punching, the punching head 803 is protected by the elastic force of the second spring 902. The punched sponge will pass under the auxiliary roller 5 on the other side and then be wound around the discharging roller 6 surface.
