[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to 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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
[0031] Please refer to Figure 1 - Figure 8 As shown in the figure, this embodiment provides a punching automatic feeder, including a base plate 1, and further including:
[0032] A feeding table 2, fixedly connected to the upper surface of the base plate 1, and a material body 7 is provided on the upper surface of the feeding table 2;
[0033] A fixed limiting component, arranged outside the feeding table 2 and used for limiting and guiding the material body 7;
[0034] A support frame 8, fixedly connected to the outside of the base plate 1;
[0035] A stamping component, arranged at the bottom of the support frame 8 and used for stamping the material body 7;
[0036] A pushing component, arranged outside the stamping component and used for automatically feeding the material body 7;
[0037] An anti-return component, arranged on the upper surface of the base plate 1 and used for preventing the material body 7 from returning.
[0038] The above working principle: When stamping the material body 7, first place the material body 7 on the feeding table 2, and then use the fixed limit component to fix and limit the material body 7. At this time, the material body 7 can be effectively guided, thus avoiding displacement and other situations of the material body 7 during the feeding process, effectively improving the stamping effect of the material body 7. After the material body 7 is fixed, the stamping component starts to operate. At this time, the material body 7 can be effectively stamped by the stamping component. During the operation of the stamping component, it will also drive the material pushing component to move synchronously. At this time, the material pushing component can effectively drive the material body 7 to move synchronously, so as to achieve the purpose of automatic feeding without manual feeding by the staff, effectively improving the feeding efficiency of the material body 7 and the overall safety factor of the device. Through the setting of the anti-backfeeding component, it can effectively prevent the material pushing component from driving the material body 7 to move backward during the reset movement, effectively improving the overall practicability of the device, saving time and effort.
[0039] In order to effectively limit and guide the material body 7, the fixed limit component includes an adjustment plate 3 fixedly connected to the outside of the feeding table 2. A bidirectional threaded rod 13 is rotatably connected to the inner wall of the adjustment plate 3. The other end of the bidirectional threaded rod 13 extends to the outside of the adjustment plate 3 and is fixedly connected to a knob 12. Threaded blocks 14 are symmetrically arranged on the outside of the bidirectional threaded rod 13. Guide grooves for the threaded blocks 14 to move are provided on the upper surface of the adjustment plate 3. Guide grooves for the movable plates 24 to move are provided on the upper surfaces of the two threaded blocks 14. Connecting plates 4 are fixedly connected to the upper surfaces of the two movable plates 24. C-shaped frames 5 are fixedly connected to the opposite sides of the two connecting plates 4. A plurality of guide rollers 6 are rotatably connected between the C-shaped frames 5 and the connecting plates 4. When it is necessary to limit and guide the material body 7, first place the material body 7 on the upper surface of the feeding table 2, and then rotate the knob 12. At this time, the knob 12 will drive the bidirectional threaded rod 13 to rotate synchronously, and the threaded blocks 14 will move synchronously on the outside of the bidirectional threaded rod 13, driving the movable plates 24 to move synchronously. The movable plates 24 will drive the connecting plates 4 to move synchronously. The connecting plates 4 will drive the C-shaped frames 5 and the guide rollers 6 to move synchronously. When the guide rollers 6 move above the material body 7, then move the guide rollers 6 downward. When the outside of the guide rollers 6 abuts against the upper surface of the material body 7, the material can be limited and guided by the guide rollers 6, thus effectively improving the stability of the material body 7 during the feeding process and avoiding displacement and other situations of the material body 7 during the feeding process, which may affect the stamping effect of the material body 7.
[0040] Considering that the height position of the guide roller 6 needs to be adjusted when fixing and limiting the material body 7, a fixed sleeve 20 is fixedly connected to the outside of the threaded block 14. A fixed rod 21 is arranged inside the fixed sleeve 20. One end of the fixed rod 21 is fixedly connected with a pull plate. A contact disc 22 is fixedly connected to the outside of the fixed rod 21. A return spring 23 is sleeved on the outside of the fixed rod 21. The return spring 23 abuts between the contact disc 22 and the fixed sleeve 20. Guide grooves for the movement of the fixed rod 21 are provided on the contact surfaces of the fixed sleeve 20 and the threaded block 14. Guide grooves for the movement of the fixed rod 21 are equidistantly arranged inside the movable plate 24. When the height position of the guide roller 6 needs to be adjusted, only need to first pull the pull plate. At this time, the pull plate will drive the fixed rod 21 to move synchronously. The fixed rod 21 will then drive the contact disc 22 to move synchronously. During the movement of the contact disc 22, the return spring 23 will be compressed. When the fixed rod 21 disengages from the guide groove inside the movable plate 24, then pull the movable plate 24 inside the threaded block 14. When the movable plate 24 drives the guide roller 6 to move to a suitable height position, then release the pull plate. At this time, the return spring 23 resets, driving the contact disc 22 and the fixed rod 21 to move synchronously. When the fixed rod 21 is inserted into the guide groove inside the movable plate 24, the threaded block 14 and the movable plate 24 can be fixed. At this time, the height position of the guide roller 6 can be fixed, so that the guide roller 6 can effectively abut against the outside of the material body 7.
[0041] In order to effectively punch the material body 7, the punching assembly includes electric cylinders 9 symmetrically arranged at the bottom of the support frame 8. The telescopic ends of the two electric cylinders 9 are fixedly connected with a pressing disc 10. A punching part 11 is fixedly connected to the bottom of the pressing disc 10. When the material body 7 needs to be punched, the electric cylinder 9 starts to operate. At this time, the electric cylinder 9 will drive the pressing disc 10 to move synchronously. The pressing disc 10 will then drive the punching part 11 to move synchronously. At this time, the material body 7 can be effectively punched by the punching part 11.
[0042] In order to effectively perform automatic feeding processing on the material body 7, the pushing component includes an L-shaped plate 15 fixedly connected to the outside of the lower pressing plate 10. A fixed frame 25 is fixedly connected to the outside of the L-shaped plate 15. A connecting rod 26 is fixedly connected to the inside of the fixed frame 25. A first scroll spring 27 is fixedly connected to the outside of the connecting rod 26. The other end of the first scroll spring 27 is fixedly connected to a rotating sleeve 28. A pushing plate 16 is fixedly connected to the outside of the rotating sleeve 28. A movable wheel 17 is fixedly connected to the bottom of the pushing plate 16. An auxiliary frame 18 is fixedly connected to the upper surface of the bottom plate 1. During the movement of the lower pressing plate 10, the L-shaped plate 15 will be driven to move synchronously. The L-shaped plate 15 then drives the pushing plate 16 to move synchronously. At this time, the pushing plate 16 will pass through the stamping hole on the upper surface of the material body 7. When the pushing plate 16 continues to move downward, the movable wheel 17 will contact the outside of the auxiliary frame 18. Since the outside of the auxiliary frame 18 is provided with an inclined surface, during the downward movement of the pushing plate 16, the movable wheel 17 will be driven to move synchronously on the inclined surface of the auxiliary frame 18. At this time, the pushing plate 16 will displace, driving the rotating sleeve 28 to rotate synchronously. The rotating sleeve 28 then stretches the first scroll spring 27 synchronously. During the inclined displacement of the pushing plate 16, the material body 7 will be driven to move synchronously. At this time, automatic feeding processing can be performed on the material body 7. After the material body 7 is stamped, the lower pressing plate 10 will be lifted upward, driving the pushing plate 16 to move synchronously. During the upward movement of the pushing plate 16, the first scroll spring 27 will reset, driving the rotating sleeve 28 to rotate synchronously. The rotating sleeve 28 then drives the pushing plate 16 to move synchronously. At this time, the pushing plate 16 can be reset, so that the pushing plate 16 can continue to perform feeding processing on the material body 7.
[0043] In addition, in order to effectively limit the pushing plate 16, a fixing plate 34 is fixedly connected to the bottom of the L-shaped plate 15. A limiting rod 35 for abutting against the pushing plate 16 is fixedly connected to the outside of the fixing plate 34. Through the arrangement of the limiting rod 35, the pushing plate 16 can be effectively limited, thus avoiding the situation of excessive reset of the pushing plate 16.
[0044] In order to prevent the material body 7 from moving backward during the reset process of the material pushing plate 16, the anti-backfeeding assembly includes a support plate 19 fixedly connected to the upper surface of the bottom plate 1. An installation groove is formed on the upper surface of the support plate 19. An inner rod 29 is fixedly connected inside the installation groove. A second scroll spring 30 is fixedly connected to the outside of the inner rod 29. The other end of the second scroll spring 30 is fixedly connected to a connection sleeve 31. A clamping plate 32 is fixedly connected to the outside of the connection sleeve 31. A limiting plate 33 for abutting against the clamping plate 32 is fixedly connected inside the installation groove. During the reset movement of the material pushing plate 16, it will come into contact with the material body 7 again. At this time, it may cause the material body 7 to move backward. Through the setting of the clamping plate 32, during the feeding process of the material body 7, the clamping plate 32 will be extruded. At this time, the clamping plate 32 will drive the connection sleeve 31 to rotate synchronously. The connection sleeve 31 then stretches the second scroll spring 30 synchronously. When the punching hole on the upper surface of the material body 7 moves above the clamping plate 32, the second scroll spring 30 resets, driving the connection sleeve 31 to rotate synchronously. The connection sleeve 31 then drives the clamping plate 32 to move synchronously. When the clamping plate 32 is clamped into the punching hole inside the material body 7, the material body 7 can be fixed by the clamping plate 32, thereby preventing the material pushing plate 16 from causing the material body 7 to move backward. When the material body 7 continues to be fed, the clamping plate 32 will be extruded again, and so on, effectively improving the overall stability and practicability of the device.
