[0007] Preferably, a curved limiting plate is fixedly connected to the side of the fixing plate near the adjusting box, and a sliding shaft is slidably connected to the inner wall of the curved limiting plate, and the sliding shaft is fixedly connected to the adjusting box.

[0008] Preferably, the radial adjustment assembly includes an adjustment plate, which is slidably connected to the interior of an adjustment box. The interior of the adjustment box has a slot that matches the adjustment plate. A first threaded rod is slidably connected between the two adjustment plates via threads. A first gear is fixedly connected to the middle position of the first threaded rod. A toothed plate is slidably connected inside the adjustment box.

[0009] Preferably, a second gear is fixedly connected to the outer wall of the second threaded rod, a pressing plate is slidably connected to the outer wall of the second gear, a first spring shaft is fixedly connected to the bottom surface of the pressing plate, and the end of the first spring shaft away from the pressing plate is fixedly connected to the adjustment box.

[0010] Preferably, the moving component includes a first moving plate, which is fixedly connected to the bottom surface of the adjusting plate.

[0012] Preferably, the tensioning assembly includes a bracket, four brackets are fixedly connected to the bottom surface of the adjustment box, the bottom surface of the bracket is rotatably connected to a second spring shaft via a shaft, the ends of the front and rear second spring shafts away from the brackets are connected to a second movable plate, the second spring shafts and the second movable plates are rotatably connected via a shaft, a connecting rod is fixedly connected between the two second movable plates, a tensioning wheel is rotatably connected to the outer wall of the connecting rod, a limiting shaft is provided on the second movable plate, the upper end of the limiting shaft extends out of the adjustment box and forms a sliding connection with the adjustment box in the upper and lower directions.

[0013] The tension wheel swing angle adjustment mechanism for a wire feeding machine provided in this embodiment of the invention has the following advantages:

[0014] 1. The adjusting box drives the fixed shaft to rotate inside the sleeve, thereby achieving angle adjustment. This allows the adjusting box to adjust the tension of the copper wire, thus reducing the possibility of excessive swaying of the tension wheel during use, which could damage the surface of the copper wire.

[0015] 2. By setting the tensioning component structure to control the tension of the copper wire movement, the copper wire will not be pulled too deeply on the surface of the wire feeding wheel due to sudden changes in tension, which would make subsequent separation difficult, thus ensuring the smooth movement of the copper wire.

[0016] 3. When the first threaded rod rotates, the adjusting plates move towards each other or in opposite directions, thereby adjusting the position of the two adjusting plates according to the diameter of the copper wire. This allows the gap between the two extrusion rollers to allow the movement of the copper wire, and the gap between the two extrusion rollers and the copper wire is small, so that the surface of the copper wire will not be damaged due to the weight of the copper wire and external pressure when the extrusion rollers limit the copper wire.

[0025] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0026] like Figure 1-7 As shown, the present invention is a tension wheel swing angle adjustment mechanism for a wire feeding machine, including a fixed bracket 5, an adjustment box 8 fixedly connected between the fixed brackets 5, and an adjustment unit 6 connected inside the adjustment box 8; a connecting plate 9 is provided on the fixed bracket 5, a tension wheel 10 is connected to the right side of the connecting plate 9, and a swing limit unit 7 is connected to the outer wall of the adjustment box 8.

[0027] The swing limiting unit 7 includes a fixed plate 71, which is fixedly connected to the upper and lower sides of the fixed bracket 5. A sleeve 73 is fixedly connected between the two fixed plates 71. A fixed shaft 74 is slidably connected to the inner wall of the sleeve 73. A cylinder 75 is rotatably connected to the fixed bracket 5 and the adjusting box 8 through the shaft. When this device is needed, the copper wire is limited and buffered by the adjusting unit 6 inside the adjusting box 8, and then enters the tension wheel 10 on the outer wall of the connecting plate 9 for tension adjustment. Thus, the output angle of the copper wire is adjusted by the use of the swing limiting unit 7. When the tension of the copper wire changes after passing through the tension wheel 10, the cylinder 75 on one side is activated to push the adjusting box 8, and the cylinder 75 on the other side pulls the adjusting box 8. Under the cooperation of the fixed plate 71 and the sleeve 73, the adjusting box 8 drives the fixed shaft 74 to rotate. The adjusting box 8 drives the fixed shaft to rotate inside the sleeve, thereby realizing the angle adjustment. This allows the adjusting box 8 to adjust the tension of the copper wire, thereby reducing the situation where excessive swing of the tension wheel during use causes damage to the surface of the copper wire.

[0028] Preferably, the adjusting unit 6 includes a radial adjusting component 61, which is connected to the upper interior of the adjusting box 8. The inner wall of the adjusting box 8 is provided with a moving component 64, and a pressing roller 62 is rotatably connected between the upper and lower moving components 64. Two corrective components 63 are connected to the inner wall of the adjusting box 8, and the corrective components 63 are located between the front and rear sets of pressing rollers 62. A tensioning component 65 is connected to the bottom surface of the adjusting box 8. By setting the radial adjusting component 61 included in the adjusting unit 6 to adjust the clamping structure of the copper wire according to the outer diameter of the copper wire, this structure can adapt to various conditions. For use with copper wires of various diameters, the correction component 63 ensures that the copper wire maintains a right angle adjustment and contacts the tensioning component 65 when separating from the extrusion roller 62. This prevents the copper wire from coming into contact with the gap at the bottom of the extrusion roller 62 due to high external tension, which could cause surface wear. The tensioning component 65 controls the tension of the copper wire during movement, preventing sudden changes in tension from causing the copper wire coil to be pulled too deeply, which could lead to difficulties in subsequent separation. This ensures smooth movement of the copper wire.

[0029] Preferably, a curved limiting plate 72 is fixedly connected to the side of the fixed plate 71 near the adjusting box 8. A sliding shaft 76 is slidably connected to the inner wall of the curved limiting plate 72, and the sliding shaft 76 is fixedly connected to the adjusting box 8. By setting the curved limiting plate 72 to be fixedly connected to the upper and lower outer walls of the adjusting unit 6, and sliding inside the curved limiting plate 72 when the adjusting box 8 moves the sliding shaft 76, the trajectory of the adjusting box 8 is limited during use, ensuring the stability of the adjusting box 8 during swing, thereby preventing damage caused by the swing amplitude of the adjusting box 8 not following the pattern.

[0030] Preferably, the radial adjustment assembly 61 includes an adjustment plate 611, which is slidably connected to the interior of an adjustment box 8. The interior of the adjustment box 8 has a groove matching the adjustment plate 611. A first threaded rod 612 is slidably connected between the two adjustment plates 611 via a thread. A first gear 613 is fixedly connected to the middle of the first threaded rod 612. A toothed plate 614 is slidably connected inside the adjustment box 8. A second threaded rod 615 is fixedly connected between the two toothed plates 614. A spring 616 is slidably sleeved on the outer wall of the second threaded rod 615. By pressing the toothed plates 614 on both sides, the adjustment plate 611 and the second threaded rod 615 are compressed, causing the second... When the threaded rod 615 and spring 616 retract, the distance between the two toothed plates 614 decreases. The toothed plates 614 move and drive the first gear 613 to rotate through the teeth on their surfaces. The first gear 613 drives the first threaded rod 612 to rotate. The threads on the outer wall of the first threaded rod 612 are arranged in opposite directions, so that when the first threaded rod rotates, the adjusting plates move towards each other or in opposite directions. This allows the position of the two adjusting plates to be adjusted according to the diameter of the copper wire, so that the gap between the two extrusion rollers can retain the movement of the copper wire. Moreover, the gap between the two extrusion rollers and the copper wire is small, so that the surface of the copper wire will not be damaged due to the weight of the copper wire and external pressure when the extrusion rollers limit the copper wire.

[0031] Preferably, a second gear 618 is fixedly connected to the outer wall of the second threaded rod 615, and a pressing plate 619 is slidably connected to the outer wall of the second gear 618. A first spring shaft 617 is fixedly connected to the bottom surface of the pressing plate 619, and the end of the first spring shaft 617 away from the pressing plate 619 is fixedly connected to the adjusting box 8. When it is necessary to adjust the position of the adjusting plate 611, the pressing plate 619 needs to be pressed to separate the pressing plate 619 from the second gear 618 between the two second threaded rods 615. The pressing plate 619 compresses the first spring shaft 617, and then the limitation on the second threaded rod 615 can be released, so that the two toothed plates 614 can slide on the surface of the second threaded rod 615 in the threaded state. The toothed plates 614 drive the first gear 613 to rotate and drive the adjusting plate 611 to move under the action of the thread. The positioning and release of the toothed plate 614 structure can be achieved simply and quickly through the cooperation of the structure.

[0032] Preferably, the moving component 64 includes a first moving plate 641, which is fixedly connected to the bottom surface of the adjusting plate 611. Two limiting rods 642 are slidably connected to the inner wall of the first moving plate 641, and a limiting plate 643 is slidably connected to the outer wall of the first moving plate 641. The limiting plate 643 is fixedly connected to the adjusting box 8. By setting two limiting rods 642 inside the first moving plate 641, the first moving plate 641 is kept stable and balanced when it slides with the adjustment plate 611. The structure of the limiting plate 643 works in conjunction with the limiting rods 642. The first moving plate 641 provides a limiting track during the sliding process, thereby ensuring that the first moving plate 641 moves along a predetermined trajectory. This ensures that the structure is not deformed by the external tension brought by the copper wire, and effectively improves the durability of the structure.

[0033] Preferably, the correction component 63 includes a fixing rod 631, which is fixedly connected to the inner wall of the adjustment box 8. A correction wheel 632 is fixedly connected to the outer wall of the fixing rod 631, and the correction wheel 632 is located at the center of the fixing rod 631. By setting the structure of the correction component 63, the corner protection function is maintained when the copper wire separates from the extrusion wheel 62, so that the copper wire will not come into contact with the gap of the extrusion wheel 62 under the action of tension at the corner, thereby preventing the copper wire from being damaged by surface extrusion during long-term tension and sudden pulling.

[0034] Preferably, the tensioning assembly 65 includes brackets 651, four brackets 651 are fixedly connected to the bottom surface of the adjusting box 8, and a second spring shaft 652 is rotatably connected to the bottom surface of the brackets 651 via a shaft. A second moving plate 653 is connected to the end of the two second spring shafts 652 away from the brackets 651. The second spring shafts 652 and the second moving plates 653 are rotatably connected via a shaft. A connecting rod 655 is fixedly connected between the two second moving plates 653. A tensioning wheel 656 is rotatably connected to the outer wall of the connecting rod 655. A limiting shaft 654 is provided on the second moving plate 653, and the upper end of the limiting shaft 654 extends out of the adjusting box 8 and forms a sliding connection with the adjusting box 8. When the copper wire... After passing through the compression wheel 62 on one side and then the corner protection of the correction wheel 632 on the same side, the wire contacts the tension wheel 656, then contacts the correction wheel 632 and the compression wheel 62 on the other side, and then passes through the adjustment box 8 to contact the tension wheel 10. After the copper wire is pulled by the swing force of the tension wheel 10, it is transmitted to the position of the second spring shaft 652 through the second moving plate 653. By setting the second spring shaft 652 and the limiting shaft 654 to form a triangular structure, higher stability is provided, and the tension is transferred to the triangular structure and the tension is separated, so that the tensioning component 65 structure can withstand more external force pulling, and the tensioning component 65 provides more tension pulling protection.

[0035] The work process is as follows:

[0036] When this device is needed, the copper wire is inserted into the adjusting box 8. The relative positions of the two adjusting plates 611 are adjusted by the radial adjusting component 61 so that the extrusion roller 62 adapts to the outer diameter of the copper wire. The copper wire is guided by the correction roller 632 of the correction component 63 to avoid contact with the bottom gap of the extrusion roller 62. The copper wire then contacts the tensioning roller 656 of the tensioning component 65. The tension of the copper wire is transmitted to the second spring shaft 652 and buffered by the triangular structure formed by the second spring shaft 652 and the limiting shaft 654.

[0037] After the copper wire passes through the adjusting box 8, it enters the tension wheel 10 for tension adjustment. When the tension of the copper wire changes after passing through the tension wheel 10, the cylinder 75 on one side is activated to push the adjusting box 8, and the cylinder 75 on the other side pulls the adjusting box 8. The adjusting box 8 drives the fixed shaft 74 to rotate under the cooperation of the fixed plate 71 and the sleeve 73. At the same time, the sliding shaft 76 slides inside the curved limit plate 72 to keep the trajectory limit of the adjusting box 8 and adjust the output angle of the copper wire to reduce the damage to the surface of the copper wire caused by excessive swing of the tension wheel.

[0038] When the position of the adjusting plate 611 needs to be adjusted, press the pressing plate 619 to separate the pressing plate 619 from the second gear 618 on the second threaded rod 615. The pressing plate 619 compresses the first spring shaft 617, releasing the limit on the second threaded rod 615. Press the toothed plates 614 on both sides to squeeze the adjusting plate 611 and the second threaded rod 615, causing the second threaded rod 615 and the spring 616 to contract. The distance between the two toothed plates 614 is reduced, and the toothed plates 614 move through the teeth on their surface to drive the first gear 613 to rotate. The first gear 613 drives the first threaded rod 612 to rotate, causing the two adjusting plates 611 to move in opposite directions, adjusting the gap between the two pressing wheels 62. After the adjustment is completed, release the pressing plate 619, the first spring shaft 617 resets, and the pressing plate 619 and the second gear 618 re-engage, completing the positioning of the toothed plate 614 structure.

[0039] It is understood that the above embodiments are merely exemplary implementations used to illustrate the principles of the present invention, and the present invention is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also considered to be within the scope of protection of the present invention.
