[0025] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0026] See also Figures 1-4 , the utility model provides a technical solution:
[0027] Example 1:
[0028] A biopsy forceps spring wire cutting device includes a waste bin 2 and a workbench 3 mounted on the upper surface of the waste bin 2. The front of the waste bin 2 is hingedly connected to a door 201 for collecting and processing cut waste, maintaining a clean work environment and reducing subsequent cleanup. Support columns 202 are fixedly connected to the upper surface of the workbench 3, and a top plate 203 is fixedly connected to the upper surface of the support columns 202. A placement frame 401 is fixedly connected to the left side of the workbench 3, and a material unloading platform 5 is fixedly connected to the right side of the workbench 3. A spring wire handling mechanism is located above the waste bin 2.
[0029] The spring wire processing mechanism includes a feeding and clamping unit and a cutting unit;
[0030] The feeding clamping unit includes a conveyor belt 402, a placement groove 301, a threaded rod 302, a connecting block 303, a screw nut 304, an arc plate 305, a ball 306 and a motor 307. The conveyor belt 402 is arranged inside the placement frame 401. The bottom of the placement frame 401 is fixedly connected to the bracket 1. The placement groove 301 is opened on both sides of the upper surface of the workbench 3. The threaded rod 302 is connected to the inside of the placement groove 301, and the threads at both ends of the threaded rod 302 are opposite. The lead screw nut 304 is threadedly connected to the threaded rod 302, the connecting block 303 is fixedly connected to the upper surface of the lead screw nut 304, the arc plate 305 is fixedly connected to the connecting block 303, and the ball 306 is set on the arc plate 305. The output end of the motor 1 307 is connected to the threaded rod 302 through a coupling. The motor 1 307 drives the threaded rod 302, so that the arc plates 305 on both sides move synchronously but in opposite directions, thereby clamping and stably conveying the spring steel wire, ensuring cutting accuracy;
[0031] The cutting unit includes a slide 7, a through slot 701, a cutting structure 702 and an electric push rod 703. The slide 7 is opened between the two placement slots 301, the through slot 701 is opened on the left side of the slide 7, the cutting structure 702 is slidably connected to the inside of the slide 7, and the output end of the electric push rod 703 is connected to the cutting structure 702. The electric push rod 703 pushes the cutting structure 702 to slide in the slide 7 to achieve precise cutting action. The through slot 701 allows waste to fall directly into the waste box 2, thereby improving cutting efficiency.
[0032] Example 2:
[0033] On the basis of Example 1, the right side of the waste bin 2 is fixedly connected to a collection box 6, and a material distribution structure is provided at the lower right side of the collection box 6. The material distribution structure includes a transmission member 602, a material distribution column 601, a gear 603, a motor 3 604 and a transfer bar 605. An outlet is provided at the lower right side of the collection box 6. The material distribution column 601 is rotatably connected to the outlet through the transfer bar 605. The output end of the motor 3 604 is connected to the middle part of the gear 603 through a coupling. The middle part of the gear 603 is fixedly connected to the transmission member 602. The transmission member 602 is fixedly connected to the transfer bar 605 on the back of the material distribution column 601. The transmission member 602 is driven by a belt, ensuring that the cut spring steel wire can be output and sorted stably and orderly. The rotation of the material distribution column 601 guides the spring steel wire to flow out in a predetermined direction, avoiding confusion and accumulation.
[0034] The unloading platform 5 is equipped with an unloading mechanism, which includes a turntable 501, a selector bar 502, a second motor 503, and a connecting shaft 504. The output end of the second motor 503 is connected to the connecting shaft 504 via a coupling. The connecting shaft 504 is rotatably connected to the unloading platform 5. The turntable 501 is fixedly connected above the connecting shaft 504, and the selector bar 502 is located outside the turntable 501. The unloading mechanism consists of two groups, one on each side of the unloading platform 5. The second motor 503 drives the turntable 501 to rotate, and the selector bar 502 selects the finished products or waste materials in an orderly manner to the designated location for subsequent collection or processing, thereby improving the degree of automation and work efficiency.
[0035] Working Principle: First, the spring wire is placed on the conveyor belt 402 within the placement frame 401. The initial movement of the conveyor belt 402 delivers the wire to the feed clamping area. Motor 1 307 is activated, driving the threaded rod 302 to rotate. Because the threads at the ends of the threaded rod 302 are opposite, the two screw nuts 304 connected to the rod 302 move synchronously but in opposite directions, either toward the center or to the sides. The movement of the screw nuts 304 drives the connecting block 303 and the curved plate 305, clamping the spring wire and ensuring stable conveyance. Balls 306 roll on the curved plate 305, reducing friction and improving movement efficiency.
[0036] When the spring wire is stably transported to the cutting position, the electric push rod 703 is activated, pushing the cutting structure 702 to slide in the chute 7, achieving precise cutting of the wire. The waste generated by cutting falls directly into the waste bin 2 through the through slot 701, completing the collection and disposal of the waste.
[0037] Finished products or scrap are delivered to the unloading platform 5, where motor 2 503 rotates the turntable 501. The distribution bar 502 on the turntable 501 orderly drops the steel wire into the collection box 6. The rotating distribution column 601 then guides the steel wire out of the collection box 6 in a predetermined direction. Motor 3 604 rotates the gear 603, which, through a belt drive, drives the transmission element 602 and the adapter bar 605, further rotating the distribution column 601, thus achieving the distribution function.
