[0020] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0021] Embodiment 1: This embodiment 1 provides a cutting device for welding material production, which is directly improved on the existing cutting device for welding material production and has a unique structure.

[0023] The top of the right side wall of the collecting trough 2 is slightly lower than the enclosed area formed by the two annular grooves. The right side surface of the cutter is flush with the inner wall of the right side wall of the collecting trough 2. The welding rod is cut using the cutter and the right side wall of the collecting trough 2. There are many ways to install the movable plate 13. For example, sliding grooves are vertically opened on the front and rear side walls of the U-shaped frame 10, and moving blocks are slidably installed in the sliding grooves. Both moving blocks are fixedly connected to the moving plate 13. A through hole is vertically opened on the upper edge of the moving block. The reset assembly includes a limit rod 14 slidably mounted in the through hole, a stop block is fixedly installed on the top of the limit rod 14, and the bottom end of the limit rod 14 is fixedly connected to the U-shaped frame 10. A second spring 15 is mounted on the limit rod 14 below the moving block.

[0024] The ejection assembly includes a fixed plate 16, a push rod 19 and a rotating lifting mechanism. The fixed plate 16 is fixedly installed on the front side wall of the collecting tank 2. A sliding locking assembly is provided on the fixed plate 16. Two left and right rotating shafts are horizontally provided along the rear side of the fixed plate 16. The two rotating shafts are fixedly connected to the sliding locking assembly. A connecting rod 18 is rotatably sleeved on the right rotating shaft; the connecting rod 18 is located just in front of the enclosed area formed by the two annular grooves. There are many options for the sliding locking assembly, for example: a notch is horizontally opened along the upper edge of the fixed plate 16, and the sliding locking assembly is clamped in the notch. The sliding locking assembly includes bolts and two clamping plates 17. The two clamping plates 17 are symmetrically arranged on the front and rear sides of the fixed plate 16, respectively. The two rotating shafts are fixedly connected to the rear clamping plate. A plurality of bolt holes are horizontally opened along the upper edge of the clamping plate 17, and the two clamping plates 17 are fixed together by bolts.

[0025] A plurality of through holes are opened transversely on the upper side of the push rod 19, one of which is provided with a bolt, and the connecting rod 18 and the push rod 19 are fixedly connected by the bolts, and an L-shaped connecting rod 23 is provided between the push rod 19 and the U-shaped frame 10, and the push rod 19 and the L-shaped connecting rod 23 conflict with each other; one end of the L-shaped connecting rod 23 faces the enclosed area of ​​the pressure plate 12 and the movable plate 13, and the other end is fixedly connected to the output end of the rotary lifting mechanism, and a tension spring 25 is fixedly installed on the fixed plate 16, and the other end of the tension spring 25 is fixedly connected to the sleeve 21; the rotary lifting mechanism includes a fixed shaft 20 fixedly installed on the workbench 1, and two limit plates 24 are spaced apart on the fixed shaft 20, and a sleeve 21 and a third spring 22 are movably mounted between the two limit plates 24 from top to bottom, and one end of the L-shaped connecting rod 23 is fixedly connected to the sleeve 21.

[0026] When we use the device to cut the welding rod, we first adjust the horizontal distance between the connecting rod 18 and the cutter according to the required length of the welding rod, and then insert one end of the welding rod into the enclosed area formed by the two annular grooves, and the two driving wheels 5 drive the welding rod to move. Since the connecting rod 18 is located right in front of the enclosed area formed by the two annular grooves, the welding rod will push the lower part of the connecting rod 18 after moving to the preset distance. The connecting rod 18 rotates to drive the push rod 19 to push the L-shaped connecting rod 23, so that one end of the L-shaped connecting rod 23 extends between the pressing plate 12 and the moving plate 13. After the position sensor senses the L-shaped connecting rod 23, it transmits a signal to the controller 9. The controller 9 controls the electric hydraulic rod 11 to move once, and the output of the electric hydraulic rod 11 is The output end drives the pressure plate 12 to move downward, thereby driving the cutter to cut the welding rod, and when the L-shaped connecting rod 23 does not enter between the pressure plate 12 and the movable plate 13, the output end of the electric hydraulic rod 11 extends and cannot drive the movable plate 13 to move downward, thereby avoiding the welding rod being cut into irregular strips due to accidental touch. After the welding rod is cut, the output end of the electric hydraulic rod 11 contracts, and the movable plate 13 returns to the starting position under the action of the second spring 15, and the push rod 19 and the L-shaped connecting rod 23 return to the starting position under the action of the tension spring 25. Through the coordinated setting of the driving mechanism and the cutting mechanism, not only can the welding rod be automatically cut into equal lengths, but also the cutting length can be adjusted, thereby improving the application range of the device.

Through the coordinated arrangement of the slide bar 6 and the first spring 8, welding rods of different diameters can be adapted, thereby improving the applicable range of the cutting device.

[0028] In actual application, the user can adjust the position of the slider 6 as needed, so that the lower driving wheel 5 can adapt to welding rods of different diameters, and then maintain the appropriate pressure between the lower driving wheel 5 and the upper driving wheel 5 through the elastic force of the first spring 8 to ensure the stable transmission and cutting effect of the welding rod. This design makes the device have a wider range of applications, can adapt to welding rods of different specifications and types, and improves the flexibility and practicality of the equipment.
