[0016] The following will be combined with the 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.
[0017] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.
[0018] Reference Figure 1-4 The present invention provides a drawbar cutting device for luggage production, comprising a workbench 1, fixedly connected to a support base 2, rotatably connected to a mounting base 3, a cutter 4 rotatably connected within the mounting base 3, and a cutting motor 5 fixedly connected to the mounting base 3 for driving the cutter 4. Two support frames 6 are fixedly connected to the workbench 1, with a limiter assembly fixedly connected between the two support frames 6 for limiting the drawbar position. The limiter assembly is located on one side of the cutter 4, and the drawbar extends through both the support frames 6 and the limiter assembly, with the drawbar corresponding to the cutter 4. A control assembly is mounted on the mounting base 3 to control the limiter assembly. Rotating the mounting base 3 drives the cutter 4 to cut the drawbar. During movement of the mounting base 3, the control assembly drives the limiter assembly to move, stabilizing the drawbar position and facilitating drawbar cutting. After cutting is completed, the mounting base 3 only needs to be lifted, and the control assembly can control the limiter assembly to stop limiting the drawbar position. This simple control eliminates the need for additional control of the limiter assembly, thereby increasing work efficiency.
[0019] A further optimized solution is that the limit assembly includes a mounting plate 7 located between the two support frames 6 and fixedly connected to the support frames 6. The two mounting plates 7 are arranged in parallel, and a through hole 8 is provided on each of the mounting plates 7. The size of the through hole 8 is larger than the size of the pull rod. A gear ring 9 is rotatably connected between the two mounting plates 7. A plurality of moving blocks 10 are symmetrically slidably connected to the mounting plates 7. The pull rod is located between the plurality of moving blocks 10. A bevel is provided on one side of the moving block 10. The bevel of the moving block 10 is arranged corresponding to the pull rod. A control gear 11 is rotatably connected to the mounting plate 7 corresponding to the moving block 10. A rack 12 meshing with the control gear 11 is fixedly connected to the side of the moving block 10 close to the control gear 11. The plurality of control gears 11 are located on the inner side of the gear ring 9 and meshed with the gear ring 9. The gear ring 9 is driven to rotate by the control assembly. During the rotation process, the gear ring 9 drives all the control gears 11 to rotate. The control gear 11 drives the moving block 10 to slide through the rack 12. During the sliding process, the moving block 10 gathers toward the center of the circle, thereby utilizing the bevel to stabilize the pull rod.
[0020] A further optimized solution is provided, in which the control assembly includes a connecting plate 13 fixedly connected to the mounting base 3, a first curved rod 14 fixedly connected to the bottom side of the connecting plate 13, a second curved rod 15 provided below the connecting plate 13, an arcuate slot 16 defined in the second curved rod 15, an end of the first curved rod 14 away from the connecting plate 13 located in the arcuate slot 16 and slidably connected to the inner wall of the arcuate slot 16, a compression spring 17 fixedly connected between the end of the first curved rod 14 located in the arcuate slot 16 and the bottom wall of the arcuate slot 16, a tooth groove adapted to the ring gear 9 is defined on the outer wall of the second curved rod 15, the second curved rod 15 located outside the ring gear 9 and meshing with the ring gear 9. When the mounting base 3 rotates downward, the first curved rod 14 drives the second curved rod 15 to move, and the second curved rod 15 meshes with the ring gear 9 through the tooth groove, driving the ring gear 9 to rotate, thereby controlling the position limiting assembly to perform the position limiting operation.
[0021] Further optimizing scheme, the mounting base 3 is fixedly connected with a handle 18, and the handle 18 is located on the side of the mounting base 3 away from the support base 2. It is convenient to control the position of the mounting base 3.
[0022] In a further optimized solution, the arc centers of the first arc rod 14, the second arc rod 15, and the arc groove 16 all coincide with the rotation center of the mounting base 3. This ensures that the second arc rod 15 can always mesh with the gear ring 9 during movement to ensure normal operation.
[0023] The working process of the utility model is as follows: when in use, the pull rod is passed through the through hole 8 to move it to the bottom of the cutting knife 4, and then the position to be cut is aligned with the cutting knife 4, and then the cutting motor 5 is started and the handle 18 is pressed downward. The handle 18 drives the mounting seat 3 to move downward, thereby driving the cutting knife 4 to move downward during the rotation process to cut the pull rod. The mounting seat 3 drives the first arc rod 14 to rotate downward during the downward rotation, and the first arc rod 14 pushes the second arc rod 15 to rotate, thereby driving the ring gear 9 to rotate. The ring gear 9 drives all control gears 11 to rotate during the rotation, thereby driving the moving block 10 to slide. The moving block 10 will gather toward the center during the sliding process, thereby stably clamping the pull rod. When the clamping is stable, the mounting seat 3 drives the cutting knife 4 to continue to move downward. At this time, the first arc rod 14 squeezes the compression spring 17, and the second arc rod 15 remains stationary, which is convenient for the cutting knife 4 to cut the stable pull rod. After the cutting is completed, the mounting base 3 is lifted, and the second arc rod 15 is reset along with the first arc rod 14, thereby resetting the motion block 10 and no longer limiting the pull rod, making it easier to move the pull rod for the next cutting.
