Specific implementation manners
[0023] 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.
[0024] Referring to Figure 1-6 , a production device for the shield door brush of a shield machine, including a shearing table 1. A blanking groove is formed on the upper end surface of the shearing table 1. A pushing plate 6 is slidably installed inside the blanking groove. The upper end surface of the shearing table 1 is fixedly installed with a feeding hopper 3 through a connecting mechanism. The connecting mechanism includes two connecting rods 2 fixedly installed on the upper end surface of the shearing table 1. Both ends of the two connecting rods 2 are fixedly connected to the outer wall of the feeding hopper 3. The outer wall of the shearing table 1 is fixedly installed with a first electric push rod 5 through a fixing mechanism. The fixing mechanism includes a fixing frame 4 fixedly installed on the outer wall of the shearing table 1. The first electric push rod 5 is fixedly installed on the inner wall of the fixing frame 4.
[0025] A moving opening matching with the first electric push rod 5 is formed on the inner wall of the blanking groove. The telescopic end of the first electric push rod 5 is fixedly connected to the outer wall of the pushing plate 6. The upper end surface of the shearing table 1 is fixedly installed with a supporting frame 7. The bottom wall of the supporting frame 7 is fixedly connected with a pressing block 9 through a lifting mechanism. The lifting mechanism includes a second electric push rod 8 fixedly installed on the bottom wall of the supporting frame 7. The telescopic end of the second electric push rod 8 is fixedly connected to the upper end surface of the pressing block 9. The upper end surface of the shearing table 1 is rotatably installed with a double-headed screw rod 11 through a moving frame 10. The outer wall of the moving frame 10 is fixedly installed with a motor 12 connected to the double-headed screw rod 11. Two moving sleeves 14 are threadedly installed on the outer wall of the double-headed screw rod 11 through a limiting mechanism. The limiting mechanism includes a limiting rod 13 fixedly installed inside the moving frame 10. The limiting rod 13 slidably penetrates through the two moving sleeves 14. The limiting rod 13 can play a limiting role on the two moving sleeves 14, so that the two moving sleeves 14 can only axially move along the outer wall of the double-headed screw rod 11.
[0026] The bottom walls of the two movable sleeves 14 are fixedly installed with a first connecting frame 15, and the interiors of the two first connecting frames 15 are rotatably connected with a second connecting frame 17 through a connecting mechanism. The connecting mechanism includes a connecting plate 16 rotatably installed inside the first connecting frame 15, and the end of the connecting plate 16 is rotatably connected to the interior of the second connecting frame 17. A shearing knife 18 is fixedly installed on the bottom walls of the two second connecting frames 17. A shearing groove cooperating with the shearing knife 18 is provided on the upper end surface of the shearing table 1. A collecting box 19 is slidably installed on the outer wall of the shearing table 1 through a sliding groove. Two guide plates 20 cooperating with the collecting box 19 are fixedly installed on the outer wall of the shearing table 1. The two guide plates 20 are arranged in opposition and tilt, so that the pushed out waste can be concentrated and dropped into the collecting box 19 to prevent the waste from falling to the outside of the collecting box 19.
[0027] When the utility model is used, the steel wire raw material is added into the upper hopper 3, and the steel wire raw material then falls from the upper hopper 3 into the blanking trough. At this time, the first electric push rod 5 can extend out of the movable opening and drive the push plate 6 to move in the blanking trough, thereby enabling the push plate 6 to push the steel wire raw material in the blanking trough, and in the process of pushing, the end of the steel wire raw material in contact with the push plate 6 can be aligned. At this time, the other end of the steel wire raw material will be uneven due to different lengths. As the first electric push rod 5 continues to extend, the push plate 6 can push the uneven end of the steel wire raw material to the shear groove, and make the uneven end pass through the shear groove, and then the second electric push rod 8 can drive the lower pressing block 9 to move downward, so that the lower pressing block 9 presses down and fixes the steel wire raw material;
[0028] When it is necessary to shear the uneven end of the steel wire material, the motor 12 can drive the double-headed screw 11 to rotate, and the double-headed screw 11 drives the two movable sleeves 14 to move by cooperating with the limit rod 13, and the two movable sleeves 14 respectively drive the first connecting frame 15 on the same side to move. During the movement, the two first connecting frames 15 can drive the two second connecting frames 17 to move downward through the cooperation of the connecting plate 16, so that the two second connecting frames 17 can jointly drive the shearing knife 18 to move downward into the shearing groove, so that the shearing knife 18 can cut off the uneven end of the steel wire material, and in the process of shearing, During the process, the extrusion of the lower pressure block 9 can prevent the steel wire material from moving during shearing, thereby preventing the shearing effect from being affected. When the shearing is completed, the second electric push rod 8 can drive the lower pressure block 9 to move upward and release the extrusion of the steel wire material. At this time, the first electric push rod 5 can drive the push plate 6 to continue to move and push the sheared steel wire material out of the blanking chute for taking it out. In this process, the sheared waste can be pushed out of the blanking chute, so that the waste falls into the collection box 19 through the cooperation of the two guide plates 20 for collection. The collection box 19 can be pulled out of the slide slot to recycle the waste inside.
[0029] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present utility model.
