[0023] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0024] like Figure 1-6 As shown, the embodiment of the present invention provides an automatic punching and waste removal machine, comprising:

[0025] A conveying device, comprising a conveying frame 1, a conveyor belt 2 mounted on the conveying frame 1, a side limit assembly 3 mounted on the side of the conveyor belt, and a front limit assembly 4 mounted on the front of the conveyor belt, with a gap between the front limit assembly 4 and the conveyor belt 2, and a roller assembly fixed in front of the conveying frame 1, the roller assembly including a lifting adjustment mechanism, and the lifting adjustment mechanism connected to a conveying roller 5;

[0026] A power device, which is installed on the conveyor frame 1 and drives the transmission roller 5 and the conveyor belt 2 to rotate;

[0027] A blanking and waste discharge device includes a blanking frame 6, a blanking assembly is provided on the top of the blanking frame 6, a blanking upper die 7 is fixed below the blanking assembly, a blanking lower die 8 is fixed below the blanking frame 6, and the blanking upper die 7 and the blanking lower die 8 correspond to each other.

[0028] The process of the utility model when in use is as follows: the stacked pearl cotton that needs to be punched is connected to the conveying device. Due to the limitation of the side limit component 3, the pearl cotton can be positioned by it. At the same time, due to the setting of the front limit component 4, the front end of the stacked pearl cotton can be limited. At this time, the conveyor belt 2 conveys the pearl cotton forward. During the transportation, the roller assembly rotates at the same time, thereby squeezing the pearl cotton so that it can move forward stably. At the same time, since the roller assembly includes a lifting and adjusting mechanism, the height of the transmission roller 5 can be adjusted, so that pearl cotton of different thicknesses can be transmitted. Finally, the pearl cotton is transmitted to the punching lower die 8 in the punching frame 6, and the pearl cotton is punched through the punching upper die 7 of the punching assembly. After the punching is completed, the waste is directly discharged from the waste discharge hole of the punching lower die 8.

[0029] Furthermore, the front limit assembly 4 includes a limit frame 9, with lifting sleeves 10 connected to both sides of the limit frame 9. The lifting sleeves 10 are movably connected to the screw 11, and the screw 11 is threadedly connected to the fastening nut 12. Specifically, the height of the limit frame 9 of the front limit assembly 4 can also be adjusted. In this way, when pearl cotton of different heights is stacked, the height of the limit frame 9 can be adjusted according to its thickness. When adjusting, the lifting sleeve 10 is raised and lowered and then tightened by the fastening nut 12.

[0030] Furthermore, the power device includes a reduction motor 13, which drives the transmission roller 5 and the conveyor belt 2 to rotate via a chain. A tensioning mechanism is also installed on the conveyor frame, and the tensioning mechanism includes a connecting cylinder 14 and a tensioning pin 15. A return spring 16 is connected to the connecting cylinder 14, and the tensioning pin 15 is connected to the return spring 16 and is limited by a clamping disc at the bottom. A tensioning sprocket 17 is also fixed to the top of the tensioning pin 15, and the chain is connected to the tensioning sprocket 17. Specifically, the power device of the utility model is a reduction motor 13, which drives the transmission roller 5 and the conveyor belt 2 to rotate, thereby achieving feeding. At the same time, after long-term operation, the chain may become loose. At this time, under the pressure of the return spring 16, the tensioning pin 15 can be moved downward, thereby achieving chain tensioning.

[0031] Further, the punching machine frame is also connected with a tensioning sprocket 17. Specifically, in order to make the chain change in direction more smoothly when connected, the punching machine frame is also connected with a tensioning sprocket 17.

[0032] Furthermore, a servo motor 18 and a plurality of electric cylinders 19 are fixed to the punching frame 6. The servo motor 18 drives the electric cylinders 19 to rotate via a synchronous belt. Specifically, the present invention fixes the servo motor 18 and the electric cylinders 19 to the punching frame 6. When the servo motor 18 rotates, it drives the electric cylinders 19 to move up and down, thereby driving the punching upper die 7 to move.

[0033] In addition, a supporting plate 21 is fixed at the front end of the conveying frame. The height of the supporting plate is slightly higher than the punching lower die. The supporting plate is connected by a rotating shaft 20. A connecting pin 22 is fixed at the bottom of the supporting frame. A buffer spring 23 is provided on the outer sleeve of the connecting pin. In this way, when the pearl cotton moves forward, it can be supported by the supporting plate so that it will not fall between the conveying device and the punching waste discharge device during the process of moving to the punching lower die. At the same time, during punching, due to the action of the buffer spring, it can move downward, so that the pearl cotton and the punching lower die are in contact during punching. After the punching is completed, the supporting plate can be quickly reset.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
