Description

Technical Field

[0001] The invention relates to the technical field of copper wire processing, and in particular to a wire release device for copper wire processing. Background Art

[0002] During the copper wire wrapping production process, the copper wire needs to be paid out. When the copper wire pay-out speed is too fast, the copper wire is very likely to get stuck, causing the insulation layer of the copper wire to be damaged. In order to protect the copper wire, it is necessary to prevent the copper wire from getting stuck during the pay-out process.

[0003] The patent publication number is CN218145008U, which discloses a copper wire unwinding device, including a frame, a movable rod movably arranged on a side panel of the frame, and a reel arranged on the movable rod. A movable hole on the side panel for installing the movable rod is provided with a clearance hole connected to the movable hole. A trigger device is provided in the clearance hole, and an elastic limiting device is provided between the clearance hole and the movable hole. The elastic limiting device can prevent the movable rod from sliding into the clearance hole under the tension of the reel during normal unwinding. The unwinding tension when the reel is stuck can open the elastic limiting device and pull the movable rod into the clearance hole to trigger the trigger device in the clearance hole.

[0004] The above patent is applied to the case where the copper wire is stuck, but it cannot prevent the copper wire from being stuck, which may easily cause damage to the copper wire. In order to protect the copper wire, we have designed a copper wire processing pay-off device that adjusts the copper wire pay-off speed to avoid the copper wire getting stuck. Summary of the invention

[0005] In order to overcome the shortcoming of the prior art that the copper wire cannot be prevented from being stuck, the present invention provides a copper wire processing pay-off device which can avoid the copper wire being stuck by adjusting the copper wire pay-off speed.

A wire unwinding port for unwinding the copper wire is provided at the upper left portion of the shell. The rear portion of the shell is open. The middle portion of the shell is rotatably connected to the rotating shaft. A winding wheel is movably clamped on the shell. The copper wire is wound on the winding wheel. The shell also comprises a clamping mechanism and an adjusting mechanism. A clamping mechanism is provided at the upper left side of the shell. The clamping mechanism is used to stop releasing the copper wire in time. An adjusting mechanism is provided at the front side of the shell. The adjusting mechanism is used to adjust the speed of releasing the copper wire and prevent the copper wire from being stuck.

[0007] As a preferred technical solution of the present invention, the clamping mechanism includes a first rotating rod, a first roller, a gear, a limiting frame and a guiding ring. Both the front and rear sides of the upper left part of the outer shell are rotatably connected with the first rotating rod. A first roller is rotatably connected between the left sides of the first rotating rods. A gear is installed on the front side of the rotating shaft. A guiding ring is installed on the front first rotating rod. An arc-shaped groove is opened in the lower part of the guiding ring. The left front part of the outer shell is slidably connected with a limiting frame. The limiting frame is inclined downward to the right. The limiting frame is movably connected with the guiding ring. The upper part of the limiting frame moves in the arc-shaped groove on the guiding ring. Sawteeth are evenly engraved on the lower right side of the limiting frame. The limiting frame is located above the left of the gear.

[0008] As a preferred technical solution of the present invention, the adjusting mechanism includes an adjusting buckle, an elastic friction block and a rubber ring. The middle part of the front of the outer shell is rotatably connected with an adjusting buckle. The thickness inside the circular part of the adjusting buckle is inconsistent. A rubber ring is sleeved on the front part of the rotating shaft. An elastic friction block is rotatably connected to the rubber ring. The inner wall of the adjusting buckle presses the elastic friction block.

[0009] As a preferred technical solution of the present invention, it further includes a prompting mechanism for prompting the amount of copper wire released. The prompting mechanism includes a connecting shaft, a pressing rod, a sliding frame and a pressing component. The middle part of the upper part of the outer shell is rotatably connected with a connecting shaft. The front side of the connecting shaft is connected with a pressing rod. The pressing rod is inclined downward to the left. The front upper part of the outer shell is slidably connected with a sliding frame. The pressing rod is movably connected with the sliding frame. A pressing component for pressing the sliding frame to move upward is arranged on the connecting shaft.

[0010] As a preferred technical solution of the present invention, the pressing component includes a rotating guiding frame, a second roller and a torsion spring. A rotating guiding frame is installed on the connecting shaft. The rotating guiding frame is located inside the outer shell. The rotating guiding frame is inclined downward to the right. Both the front and rear sides of the lower right part of the rotating guiding frame are rotatably connected with a second roller. The second rollers are both pressed on the copper wire on the winding wheel. A torsion spring is wound around the front part of the connecting shaft. The front and rear ends of the torsion spring are respectively connected with the outer shell and the connecting shaft.

[0011] As a preferred technical solution of the present invention, it further includes a closing mechanism for closing the rear part of the outer shell. The closing mechanism includes a rotating cover, a rotating buckle and a fixing block. The rear side of the connecting shaft is rotatably connected with a rotating cover. The rotating cover covers the rear part of the outer shell. The upper left part of the rear of the outer shell is rotatably connected with a rotating buckle. A groove for the rotating buckle to insert is opened in the upper left part of the rotating cover. A fixing block is installed on the upper front part of the rotating cover. The rotation of the rotating cover drives the fixing block to rotate. When the fixing block rotates to contact the connecting shaft, the fixing block presses the connecting shaft to rotate.

[0012] As a preferred technical solution of the present invention, it further includes a lifting mechanism for conveniently lifting the outer shell. The lifting mechanism includes an elastic rubber block and a handle. The upper right part of the outer shell is rotatably connected with a handle.

[0013] As a preferred technical solution of the present invention, it also includes a sliding mechanism for preventing the copper wire from directly rubbing against the shell when released. The sliding mechanism includes a second fixed frame and a pulley. The second fixed frame is installed at the wire release port of the shell. The pulley is rotatably connected to the second fixed frame. The copper wire rests on the pulley when released from the shell.

[0014] The present invention has the following advantages:

[0015] 1. In the process of releasing the copper wire, the speed of the copper wire release can be adjusted by adjusting the rotation speed of the shaft, so as to avoid the copper wire being released too quickly and causing the copper wire to accumulate and get stuck, thereby avoiding the copper wire being stuck and damaged, which is beneficial to protecting the copper wire;

[0016] 2. After the required length of copper wire is pulled out, the saw teeth on the driving limit frame are pressed on the gear, which can quickly stop the rotation of the shaft, thereby preventing the shaft from continuing to rotate under the action of inertia and releasing excess copper wire, thereby preventing the accumulation of excess copper wire and wire damage, which is beneficial to the protection of the copper wire;

[0017] 3. In the process of releasing the copper wire, the amount of copper wire released can be judged by the distance the sliding frame moves upward, so that the copper wire release can be stopped in time, which is conducive to improving the accuracy of the copper wire release amount and avoiding copper wire accumulation and wire jam;

[0018] 4. In the process of releasing the copper wire, the outer shell is covered by a rotating cover to prevent the winding wheel from falling out of the outer shell, thereby facilitating the safe and stable release of the copper wire;

[0019] 5. When you need to take the copper wire processing releaser, separate the handle from the elastic rubber block, and then you can take the copper wire processing releaser by the handle, which is convenient;

[0020] 6. When releasing the copper wire, the copper wire is close to the pulley. The rotation of the pulley can prevent the copper wire from being damaged by direct friction with the outer shell, thereby protecting the copper wire and facilitating the safe release of the copper wire.

Detailed implementation manners

[0037] The present invention will be further described in detail below in conjunction with the drawings and specific implementation manners, but the protection scope and application scope of the present invention are not limited.

[0038] Example 1

[0039] A wire pay-off device for copper wire processing, as Figure 1 、 Figure 2 、 Figure 3 and Figure 4 shown, includes a base 1, a housing 2, a winding wheel 21, a rotating shaft 3, a clamping mechanism 4 and an adjusting mechanism 5. The housing 2 is welded to the base 1. An unwinding port for discharging copper wire is opened in the upper left part of the housing 2. The rear part of the housing 2 is open, facilitating the replacement of the winding wheel 21. The rotating shaft 3 is rotatably connected to the middle of the housing 2. The winding wheel 21 is movably clamped to the housing 2. The copper wire is wound on the winding wheel 21. A clamping mechanism 4 is provided on the upper left side of the housing 2, and an adjusting mechanism 5 is provided on the front side of the housing 2.

[0040] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 shown, the clamping mechanism 4 includes a first rotating rod 41, a first roller 42, a gear 43, a limiting frame 44 and a guiding ring 45. The number of the first rotating rods 41 is two. The two first rotating rods 41 are respectively rotatably connected to the front and rear sides of the upper left part of the housing 2. The first roller 42 is rotatably connected between the left sides of the two first rotating rods 41. A gear 43 is welded to the front side of the rotating shaft 3. A guiding ring 45 is fixedly connected to the front first rotating rod 41. An arc-shaped groove is opened in the lower part of the guiding ring 45. The limiting frame 44 is slidably connected to the left front part of the housing 2. The limiting frame 44 is inclined downward to the right. The limiting frame 44 is movably connected to the guiding ring 45. The upper part of the limiting frame 44 moves in the arc-shaped groove on the guiding ring 45. Sawteeth are evenly engraved on the lower right side of the limiting frame 44. The limiting frame 44 is located above the left of the gear 43.

[0041] As Figure 1 、 Figure 4 、 Figure 7 、 Figure 8 and Figure 9 shown, the adjusting mechanism 5 includes an adjusting buckle 51, an elastic friction block 52 and a rubber ring 53. The adjusting buckle 51 is rotatably connected to the middle of the front part of the housing 2. The thickness inside the circular part of the adjusting buckle 51 is inconsistent. The rubber ring 53 is sleeved on the front part of the rotating shaft 3. An elastic friction block 52 is rotatably connected to the rubber ring 53. The inner wall of the adjusting buckle 51 presses against the elastic friction block 52.

[0042] ​​​​​​​​​Initially, the wire winding wheel 21 is clamped on the outer shell 2. When it is necessary to release the copper wire from the wire winding wheel 21, the copper wire is pulled out from the wire outlet of the outer shell 2, and the wire winding wheel 21 rotates accordingly. After pulling out the required length of copper wire, the first rotating rod 41 is rotated downward. The downward rotation of the first rotating rod 41 causes the guiding ring 45 to rotate. The rotation of the guiding ring 45 squeezes the limiting frame 44 to slide rightward and downward. The sawteeth on the limiting frame 44 are then pressed against the gear 43, so that the rotating shaft 3 can be quickly stopped from rotating, avoiding the continuous rotation of the rotating shaft 3 under the action of inertia and releasing excess copper wire, which is beneficial to accurately releasing the required amount of copper wire and can prevent the excess copper wire from being released and getting stuck and damaged, thus facilitating the protection of the copper wire. The first roller 42 rotates downward to press on the end of the copper wire, making it convenient to directly pull out the copper wire next time. When releasing the copper wire, the adjusting buckle 51 can be rotated. The rotation of the adjusting buckle 51 squeezes the rubber ring 53, and the rubber ring 53 then squeezes the elastic friction block 52. When the part with a larger inner wall thickness of the adjusting buckle 51 squeezes the rubber ring 53, the squeezing force of the rubber ring 53 on the elastic friction block 52 is large, and the rotation speed of the rotating shaft 3 is slow. When the part with a smaller inner wall thickness of the adjusting buckle 51 squeezes the rubber ring 53, the squeezing force of the rubber ring 53 on the elastic friction block 52 is small, and the rotation speed of the rotating shaft 3 is fast. In this way, the rotation speed of the rotating shaft 3 can be adjusted, so as to adjust the speed at which the copper wire is released, which is beneficial to the rapid release and stopping of the copper wire, and further helps to avoid the accumulation of excess copper wire being released, thereby further preventing the copper wire from getting stuck and damaged. When it is necessary to release the copper wire next time, the first rotating rod 41 is rotated upward, so that the first roller 42 rotates upward to reset, and then the guiding ring 45 rotates reversely to reset. The guiding ring 45 squeezes the limiting frame 44 to slide leftward and upward to disengage from the gear 43, and then the copper wire can be pulled out. When it is necessary to replace the wire winding wheel 21, the wire winding wheel 21 is removed, and a new wire winding wheel 21 is clamped on the rotating shaft 3.

[0043] Embodiment 2

[0044] On the basis of Embodiment 1, as Figure 3 、 Figure 4 、 Figure 10 and Figure 11As shown in the figure, it further includes a prompting mechanism 6. The prompting mechanism 6 includes a connecting shaft 61, a rotating guide frame 62, a second roller 63, a pressing rod 64, a sliding frame 65 and a torsion spring 66. The connecting shaft 61 is rotatably connected to the middle of the upper part of the outer shell 2. A rotating guide frame 62 is welded on the connecting shaft 61. The rotating guide frame 62 is located inside the outer shell 2 and is inclined downward to the right. The number of the second rollers 63 is two, and the two second rollers 63 are respectively rotatably connected to the front and rear sides of the lower right part of the rotating guide frame 62. The second rollers 63 are both pressed on the copper wire on the winding wheel 21. The torsion spring 66 is wound around the front part of the connecting shaft 61, and the front and rear ends of the torsion spring 66 are respectively connected to the outer shell 2 and the connecting shaft 61. A pressing rod 64 is welded on the front side of the connecting shaft 61, and the pressing rod 64 is inclined downward to the left. The sliding frame 65 is slidably connected to the upper front part of the outer shell 2, and the pressing rod 64 is movably connected to the sliding frame 65.

[0045] Initially, the second roller 63 is pressed on the copper wire on the winding wheel 21, and the torsion spring 66 undergoes a torsional deformation. As the copper wire on the winding wheel 21 decreases, the elastic force of the torsion spring 66 causes the connecting shaft 61 to rotate clockwise and always press on the copper wire. The clockwise rotation of the connecting shaft 61 causes the pressing rod 64 to rotate clockwise, and the clockwise rotation of the pressing rod 64 presses the sliding frame 65 to move upward. In this way, during the process of releasing the copper wire, people can judge the amount of copper wire released according to the upward movement distance of the sliding frame 65, which is beneficial to improving the accuracy of the released copper wire amount. When replacing the winding wheel 21, the second roller 63 is pressed on the copper wire on the winding wheel 21, and the torsion spring 66 undergoes a torsional deformation.

[0046] As Figure 2 、 Figure 12 and Figure 13 shown in the figure, it further includes a closing mechanism 7. The closing mechanism 7 includes a rotating cover 71, a rotating buckle 72 and a fixed block 73. The rotating cover 71 is rotatably connected to the rear side of the connecting shaft 61, and the rotating cover 71 covers the rear part of the outer shell 2. The rotating buckle 72 is rotatably connected to the upper left side of the rear part of the outer shell 2. A groove for the rotating buckle 72 to insert is opened in the upper left part of the rotating cover 71, and a fixed block 73 is welded on the upper front part of the rotating cover 71.

[0047] When it is necessary to replace the wire winding wheel 21, turn and open the rotating buckle 72, and turn and open the rotating cover 71. After that, the wire winding wheel 21 can be replaced. When the rotating cover 71 rotates, it drives the fixed block 73 to rotate. When the fixed block 73 rotates to contact the connecting shaft 61, the fixed block 73 squeezes the connecting shaft 61 to rotate, so that the second roller 63 rotates away from the wire winding wheel 21 through the rotating guide frame 62, and the torsion spring 66 undergoes a torsional deformation. In this way, when the rotating cover 71 is opened, it can be avoided that the second roller 63 hinders the replacement of the wire winding wheel 21, which is beneficial to improving the efficiency of replacing the wire winding wheel 21. When the replacement of the wire winding wheel 21 is completed, reverse the rotating cover 71 so that the rotating cover 71 covers the outer shell 2. When the rotating cover 71 rotates in reverse, the fixed block 73 no longer squeezes the connecting shaft 61, and the elastic force of the torsion spring 66 causes the second roller 63 to press on the copper wire of the replaced wire winding wheel 21. Then reverse the rotating buckle 72 to lock the rotating cover 71, so that it can be avoided that the wire winding wheel 21 falls out of the outer shell 2 when releasing the copper wire, which is beneficial to safely and stably release the copper wire.

[0048] As Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 14 shown, it further includes a lifting mechanism 8. The lifting mechanism 8 includes an elastic rubber block 81 and a handle 82. The handle 82 is installed on the upper right part of the outer shell 2 through a bearing, and the elastic rubber block 81 is fixedly connected to the lower right part of the outer shell 2. The handle 82 is stuck in the elastic rubber block 81.

[0049] When it is necessary to carry the wire pay-off device for copper wire processing, turn the handle 82 so that the handle 82 disengages from the elastic rubber block 81. After that, the wire pay-off device for copper wire processing can be taken through the handle 82, which has good convenience. When it is not necessary to carry the wire pay-off device for copper wire processing, reverse the handle 82 and make the handle 82 stuck on the elastic rubber block 81, so as to avoid the handle 82 being damaged due to random shaking, which is beneficial to protecting the handle 82.

[0050] As Figure 2 and Figure 15 shown, it further includes a sliding mechanism 9. The sliding mechanism 9 includes a second fixing frame 91 and a pulley 92. The second fixing frame 91 is welded at the wire pay-off opening of the outer shell 2, and the pulley 92 is rotatably connected to the second fixing frame 91. When the copper wire is released from the outer shell 2, it is placed on the pulley 92.

[0051] When using the wire pay-off device for copper wire processing, the copper wire is released from the wire pay-off opening of the outer shell 2 in a state of closely adhering to the pulley 92. Through the rotation of the pulley 92, it can be avoided that the copper wire is directly rubbed against the outer shell 2 and damaged, so that the copper wire can be protected, which is beneficial to safely releasing the copper wire.

[0052] The above embodiments are provided for those skilled in the art to implement or use the present invention. Those skilled in the art can make various modifications or changes to the above embodiments without departing from the inventive concept of the present invention. Therefore, the protection scope of the present invention is not limited by the above embodiments, but should be the maximum scope that conforms to the innovative features mentioned in the claims.
