[0025] This invention provides the following description with reference to the accompanying drawings to aid in a comprehensive understanding of the various embodiments of the invention as defined by the claims and their equivalents. The description includes various specific details to aid understanding, but these details should be considered exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the invention.

[0026] In the description of this utility model, the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0027] It should be understood that when one element (e.g., the first element) is “connected” to another element (e.g., the second element), the element may be directly connected to the other element, or there may be an intermediary element (e.g., the third element) between the element and the other element.

[0028] An embodiment of this utility model provides a wire cutting machine, such as... Figure 1-8 As shown, it includes the following arranged sequentially along the direction of wire transmission:

[0029] The first wire guiding mechanism 100 includes two wire guiding wheels 110 with tangent edges, and the periphery of each wire guiding wheel 110 is provided with a first wire groove 120 for guiding the wire through; and,

[0030] The cutting mechanism 200 includes two guide wheels 210 and a tangent wheel 220 that can rotate along the direction of wire transport. The tangent wheel 220 has a second groove 260 around its periphery for guiding the wire through. A cutting device 230 is provided on the tangent wheel 220. The cutting device 230 includes two cutting blades 240 that are rotatably connected to the tangent wheel 220. The two guide wheels 210 are respectively located on both sides of the tangent wheel 220. During the process of the tangent wheel 220 rotating and driving the cutting device 230 through the two guide wheels 210, the two guide wheels 210 respectively abut against the cutting blades 240 and drive the two cutting blades 240 to move closer to each other to cut the wire.

[0031] The first wire guiding mechanism 100 includes two wire guiding rollers 110 with tangent edges. A first groove 120 is provided around the periphery of each wire guiding roller 110 to guide the wire through. This design ensures stable wire feeding before entering the cutting mechanism 200, preventing wire deviation or twisting during feeding. The wire is guided to the cutting mechanism 200 through the first groove 120, allowing for a smooth transition between the two wire guiding rollers 110, reducing friction and wear. Two guide rollers 210 are respectively positioned on either side of the cutting roller 220. The cutting roller 220 can rotate along the wire feeding direction. In actual operation, cutting rollers 220 of different diameters can be selected according to the required wire length. A second groove 260 is provided around the periphery of the cutting roller 220 to guide the wire through, ensuring stable wire feeding during cutting and preventing wire deviation or twisting on the cutting roller 220. Before entering the cutting mechanism 200, the wire first passes through the first groove 120 of the first lead wire mechanism 100, and then enters the second groove 260 of the cutting wheel 220. The design of the second groove 260 is similar to that of the first groove 120, both designed to ensure smooth wire feeding. The cutting device 230 includes two cutting blades 240, which are rotatably connected to the cutting wheel 220. The cutting mechanism 200 is used to cut the wire. The rotation of the cutting wheel 220 drives the cutting device 230 through two guide wheels 210 to achieve the cutting action. Through the abutment action of the guide wheels 210, the cutting blades 240 can accurately approach each other, thereby achieving high-precision cutting. The design of the lead wheel 110 and the guide wheel 210 can effectively stabilize the wire feeding and cutting process, reducing wire deviation and vibration during operation. This design is suitable for various specifications of wires; by adjusting the size of the lead wheel 110 and the cutting blades 240, the cutting needs of wires with different diameters can be met.

[0032] The working principle of this utility model is as follows:

[0033] The guide wheels 210, located on either side of the tangent wheel 220, serve to change the position of the cutting blade 240. As the tangent wheel 220 rotates and drives the cutting device 230 through the two guide wheels 210, the two guide wheels 210 respectively abut against the cutting blade 240, driving the two cutting blades 240 closer together. When the tangent wheel 220 rotates, the cutting blades 240, under the abutment of the guide wheels 210, move closer together, ultimately completing the cutting of the wire. This design enables fast and precise cutting while reducing errors during the cutting process.

[0034] In some embodiments, the cutting mechanism 200 has a cutting state and a waiting-to-be-cut state. When the cutting mechanism 200 cuts the wire, the cutting mechanism 200 is in the cutting state. The cutting device 230 also includes an elastic mechanism. When the cutting device 230 releases the abutment of the guide wheel 210, the elastic mechanism applies an elastic force to the cutting blade 240 so that the cutting mechanism 200 maintains the waiting-to-be-cut state.

[0035] When the cutting mechanism 200 is cutting a wire, it is in the cutting state. At this time, the cutting wheel 220 rotates, and the cutting blades 240 approach each other under the action of the guide wheel 210, completing the cutting of the wire. When the cutting mechanism 200 is not performing a cutting operation, it is in the waiting-to-cut state. At this time, the cutting blades 240 need to remain in their initial positions, waiting for the next cutting operation. The elastic mechanism is part of the cutting device 230 and is connected to the cutting blades 240. The main function of the elastic mechanism is to apply an elastic force to the cutting blades 240 when the cutting device 230 releases its contact with the guide wheel 210, keeping the cutting mechanism 200 in the waiting-to-cut state. When the cutting mechanism 200 is in the cutting state, the guide wheel 210 abuts against the cutting blades 240, driving the cutting blades 240 to approach each other, completing the cutting action. At this time, the elastic mechanism is compressed or stretched, storing elastic potential energy. When the cutting action is completed, the guide wheel 210 no longer abuts against the cutting blades 240. At this point, the elastic mechanism releases its elastic potential energy, applying an elastic force to the cutting blade 240, causing it to return to its initial position and maintain its ready-to-cut state. The introduction of the elastic mechanism ensures that the cutting blade 240 quickly returns to its initial position after each cut, preventing it from deviating from its initial position due to inertia or external forces, thereby improving cutting stability and repeatability. The elastic mechanism can be made of springs, elastic rubber, or other elastic materials. For example, a spring can be installed on the support structure of the cutting blade 240. When the cutting blade 240 is abutted by the guide wheel 210, the spring is compressed; when the guide wheel 210 releases its contact, the spring returns to its original state, pushing the cutting blade 240 back to its initial position. The elastic mechanism ensures that the cutting blade 240 quickly returns to its initial position after each cut, avoiding cutting errors caused by positional deviations of the cutting blade 240. Through the action of the elastic mechanism, the impact force between the cutting blade 240 and the guide wheel 210 can be reduced, thereby extending the service life of both the cutting blade 240 and the guide wheel 210.

[0036] In some embodiments, a plurality of cutting devices 230 are provided, and the plurality of cutting devices 230 are arranged on the tangent wheel 220 at a preset distance.

[0037] Several cutting devices 230 are provided, each positioned at a preset distance on the cutting wheel 220. The preset distance can be adjusted according to actual needs, such as the length of the wire, the number of segments to be cut, or the cutting interval. With multiple cutting devices 230 on the cutting wheel 220, different lengths of wire can be cut according to the position of the cutting devices 230 as the wheel rotates. By providing multiple cutting devices 230 on the cutting wheel 220, when different lengths of wire are needed, it is not necessary to replace the cutting wheel 220; simply adding a cutting device 230 to the wheel 220 will suffice. By using multiple cutting devices 230, multiple wires can be cut in a single operation, significantly improving production efficiency. The preset distance can be adjusted according to actual needs, allowing the equipment to adapt to different cutting tasks. For example, when producing multiple wire segments, the distance between the cutting devices 230 can be adjusted according to the required wire length. In some embodiments, each cutting device 230 is equipped with a resilient mechanism to ensure that the cutting blade 240 can quickly return to its initial position after each cut, thereby improving the stability and repeatability of the cut.

[0038] In some embodiments, the cutting blade 240 includes a ramp portion 270, the height of which gradually decreases in the rotation direction of the tangent wheel 220.

[0039] The cutting blade 240 has a ramp 270, the height of which gradually decreases in the rotation direction of the tangent wheel 220. The design of the ramp 270 optimizes the contact between the cutting blade 240 and the wire, reduces resistance and wear during the cutting process, and improves cutting efficiency and quality.

[0040] The working principle of this embodiment is as follows: When the tangent wheel 220 rotates, the cutting blade 240 gradually approaches the wire. The height of the ramp 270 gradually increases, thereby gradually increasing the contact area between the cutting blade 240 and the wire, thus achieving a smooth cut. The design of the ramp 270 reduces the direct impact between the cutting blade 240 and the wire, reduces wear on the cutting blade 240, and extends the service life of the cutting blade 240. Guided by the ramp 270, the cutting blade 240 can cut the wire more evenly, reducing burrs and unevenness generated during the cutting process.

[0041] In some embodiments, the wire cutting machine further includes a straightening mechanism 300 disposed between the first lead-in mechanism 100 and the cutting mechanism 200, the straightening mechanism 300 being used to straighten the wire to be cut.

[0042] The straightening mechanism 300 may include multiple straightening rollers or straightening wheels, which can straighten the wire at multiple points. For example, multiple straightening rollers can be used to straighten the wire at multiple points, gradually eliminating bending and twisting of the wire. The straightening mechanism 300 can ensure that the wire is in a straight state before entering the cutting mechanism 200, thereby improving the cutting accuracy and quality. Through the pre-treatment of the straightening mechanism 300, the wire will not have cutting errors due to bending or twisting during the cutting process.

[0043] Furthermore, the straightening mechanism 300 includes a rotatable straightening roller 310, the rotation direction of the straightening roller 310 being perpendicular to the wire conveying direction, and a plurality of straightening blocks 320 being provided inside the straightening roller 310, the straightening blocks 320 being provided with straightening holes 330 of a preset diameter, the straightening holes 330 being for the wire to pass through.

[0044] The straightening mechanism 300 includes a rotatable straightening roller 310, the rotation direction of which is perpendicular to the wire conveying direction. The straightening roller 310 straightens the wire using internal straightening blocks 320, ensuring the wire is straight before entering the cutting mechanism 200. The straightening roller 310 contains several straightening blocks 320, each with a straightening hole 330 of a preset diameter. In some embodiments, the straightening blocks 320 can be replaced or adjusted according to different wire diameters to adapt to different cutting requirements. The rotation direction of the straightening roller 310 is perpendicular to the wire conveying direction; this design allows for more effective wire straightening and reduces bending and twisting during conveying. By replacing or adjusting the straightening blocks 320, the straightening mechanism 300 can adapt to wires of different diameters, improving the versatility and flexibility of the equipment.

[0045] The working principle of this embodiment is as follows: The wire passes through the first wire groove 120 of the first wire guide mechanism 100 and enters the straightening hole 330 of the straightening roller 310. The straightening roller 310 rotates during wire conveying, and the straightening hole 330 in the straightening block 320 straightens the wire. The straightened wire then enters the second wire groove 260 of the cutting wheel 220 and finally reaches the cutting mechanism 200 for cutting.

[0046] Furthermore, the straightening roller 310 is provided with a number of mounting slots 340, which are spaced apart along the length of the straightening roller 310, and the straightening block 320 is detachably installed in the mounting slot 340.

[0047] The straightening roller 310 is provided with several mounting slots 340, which are spaced apart along the length of the straightening roller 310. The mounting slots 340 are used to mount straightening blocks 320, allowing for easy removal and replacement of the straightening blocks 320. The straightening blocks 320 are fixed inside the straightening roller 310 via the mounting slots 340. The design of the mounting slots 340 ensures that the straightening blocks 320 remain stable when the roller rotates. When it is necessary to replace the straightening blocks 320 to accommodate wires of different diameters, the straightening blocks 320 can be easily removed and replaced from the mounting slots 340. The straightening blocks 320 can be installed in the mounting slots 340 using screws, clips, or other fixing devices, ensuring that they do not loosen during roller rotation.

[0048] Furthermore, the straightening mechanism 300 also includes bolts 350 for fixing the straightening block 320, and the bolts 350 are threadedly connected to the straightening roller 310.

[0049] The straightening mechanism 300 also includes bolts 350 for fixing the straightening block 320, which are threadedly connected to the straightening roller 310. The bolts 350 securely fix the straightening block 320 within the straightening roller 310 via the threaded connection, ensuring stability of the straightening block 320 as the straightening roller 310 rotates. The straightening block 320 is placed within the mounting groove 340 of the straightening roller 310 and then secured by the bolts 350. The threaded connection of the bolts 350 to the straightening roller 310 ensures that the straightening block 320 will not loosen during roller rotation. When the straightening block 320 needs to be replaced, it can be easily removed by simply loosening the bolts 350. This design facilitates maintenance and replacement, improving the flexibility and versatility of the equipment.

[0050] In some embodiments, a second wire guide mechanism 400 is provided between the straightening mechanism 300 and the cutting mechanism 200, the second wire guide mechanism 400 being used to guide the wire into the cutting mechanism 200.

[0051] A second wire guide mechanism 400 is provided between the straightening mechanism 300 and the cutting mechanism 200. The second wire guide mechanism 400 guides the wire into the cutting mechanism 200, further ensuring that the wire is in the correct position and orientation before cutting. The second wire guide mechanism 400 can adopt the same structure as the first wire guide mechanism 100, which will not be described in detail here. Guided by the second wire guide mechanism 400, the wire will not cause cutting errors due to positional deviations when entering the cutting mechanism 200. The design of the second wire guide mechanism 400 can reduce the shaking and deviation of the wire during transport, improving the stability of the equipment.
