Description

Technical Field

[0001] This utility model relates to the field of aluminum wire production equipment, and in particular to a wire feeding structure. Background Technology

[0002] For example, metal wires such as copper and aluminum wires need to be stretched multiple times to reduce their diameter from thick to thin. For instance, the wire feeding frame with publication number CN218144999U uses a handwheel and a lead screw nut to move the first lifting component to the left, then loads the cable reel. The handwheel then moves the first lifting component to the right, where the first and second lifting components clamp the cable reel. Finally, the operation of the first motor on the first lifting component and the second motor on the second lifting component raises the cable reel. However, in this structure, the synchronization rate of the first and second motors may be off, making it impossible to ensure that the cable reel is raised and lowered horizontally as a whole.

[0003] It is evident that existing technologies still need improvement and enhancement. Utility Model Content

Detailed Implementation

[0019] This utility model provides a wire feeding structure. To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following describes this utility model in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit the scope of protection of this utility model.

[0020] Please see Figure 1 and Figure 2This utility model provides a wire feeding structure, including a frame 1, a first lifting member 2 and a second lifting member 3 disposed on the frame 1 and arranged left and right, and a lifting drive mechanism 4 disposed between the first lifting member 2 and the second lifting member 3; the first lifting member 2 includes a vertically extending first lead screw 21, a first nut seat 22 threadedly connected to the first lead screw 21, a first lifting frame 23 fixedly connected to the first nut seat 22, and a first bearing seat 24 disposed on the frame 1 and rotatably connected to the first lead screw 21; the second lifting member 3 includes a vertically extending second lead screw 31, a second nut seat 32 threadedly connected to the second lead screw 31, and a first lifting frame 23 fixedly connected to the second nut seat 32. The first lifting frame 21 includes a second lifting frame 33 fixedly connected to the frame 1, and a second bearing seat 34 mounted on the frame 1 and rotatably connected to the second lead screw 31. The lifting drive mechanism 4 includes a lifting motor 41 mounted on the frame 1, a drive gear 42 connected to the output end of the lifting motor 41, a transmission gear 43 meshing with the drive gear 42 and mounted on the second lead screw 31, a drive wheel 44 mounted on the second lead screw 31, a driven wheel 45 mounted on the first lead screw 21, and a synchronous belt 46 wound between the drive wheel 44 and the driven wheel 45. A clamping mechanism 5 for clamping both sides of the spool 10 is also provided between the first lifting frame 23 and the second lifting frame 33.

[0021] When the wire feeding structure is in operation: the lifting motor 41 starts, outputting power to drive the drive gear 42 to rotate. The drive gear 42 meshes with the transmission gear 43, thereby causing the second lead screw 31 to rotate. Simultaneously, the driving wheel 44 on the second lead screw 31 drives the driven wheel 45 on the first lead screw 21 to rotate via the synchronous belt 46, achieving synchronous rotation of the first lead screw 21 and the second lead screw 31. As the first lead screw 21 and the second lead screw 31 rotate, their respective first nut seats 22 and second nut seats 32 move vertically along the first lead screw 21 and the second lead screw 31, thereby causing the first lifting frame 23 and the second lifting frame 33 to descend synchronously, facilitating material feeding. When the clamping mechanism 5 descends to be concentric with the spool 10, the clamping mechanism 5 between the two clamps the two sides of the spool 10. After clamping is complete, the lifting motor 41 starts again, using the rotation of the first lead screw 21 and the second lead screw 31 to drive the first lifting frame 23 and the second lifting frame 33, as well as the spool 10, to rise synchronously and smoothly.

[0022] The aforementioned wire feeding structure, through the transmission design of the synchronous belt 46, the driving pulley 44, and the driven pulley 45, ensures that the first lead screw 21 and the second lead screw 31 rotate synchronously, and that the first lifting frame 23 and the second lifting frame 33 rise and fall synchronously. This solves the problem of motor synchronization rate deviation and ensures that the wire drum 10 rises and falls horizontally. The lifting drive mechanism 4 adopts a combination of gear meshing and synchronous belt 46 transmission, which ensures stable transmission, high power transmission efficiency, and reduces the possibility of wire drum 10 tilting due to transmission errors.

[0023] In some embodiments, the first lead screw 21 is provided with vertically extending first guide rods 25 in both its front and rear directions. The first guide rods 25 are fixedly connected to the frame 1. The first lifting frame 23 is provided with a first guide cylinder 26, which is slidably connected to the corresponding first guide rod 25. The second lead screw 31 is provided with vertically extending second guide rods 35 in both its front and rear directions. The second guide rods 35 are fixedly connected to the frame 1. The second lifting frame 33 is provided with a second guide cylinder 36, which is slidably connected to the corresponding second guide rod 35. Through the sliding cooperation of the guide rods and guide cylinders, precise guidance is provided for the lifting frame, preventing it from tilting or swaying during lifting and ensuring that the spool 10 always remains horizontal. The arrangement of multiple sets of guide rods enhances the stability and load-bearing capacity of the overall structure, enabling it to better support the weight of the spool 10 and the wire.

[0024] In some embodiments, the clamping mechanism 5 includes a clamping nut seat 51 threadedly connected to the first lifting frame 23, a clamping screw 52 rotatably connected to the clamping nut seat 51, a movable top cone 53 disposed at the inner end of the clamping screw 52, ​​a handwheel 54 disposed at the outer end of the clamping screw 52, ​​and a fixed top cone 55 disposed on the second lifting frame 33. The movable top cone 53 and the fixed top cone 55 are arranged opposite to each other and are respectively used to insert into the corresponding insertion holes on the spool 10. In use, by rotating the handwheel 54, the clamping screw 52 is driven to rotate, thereby flexibly adjusting the position of the movable top cone 53, which facilitates the loading and unloading of the spool 10 and can also adapt to spools 10 of different sizes, making it highly versatile. In addition, the movable top cone 53 and the fixed top cone 55 are inserted into the insertion holes of the spool 10 to achieve end positioning and securely clamp the spool 10.

[0025] In some embodiments, the second lifting frame 33 is further equipped with a rotary motor 61, the output end of which is connected to a reducer 62, and the output end of the reducer 62 is fixedly connected to the fixed top cone 55. After the rotary motor 61 starts, it outputs power, which is reduced and increased in torque by the reducer 62, and then transmitted to the fixed top cone 55, causing the fixed top cone 55 to drive the spool 10 to rotate. When the spool 10 rotates, the wire is pulled out from the spool 10, realizing the wire feeding operation.

[0026] In some embodiments, the first lifting frame 23 is further provided with a fixing mechanism for fixing the clamping screw 52. The fixing mechanism can be implemented by a locking nut and a locking handle located at the end of the clamping nut seat 51. In use, the locking nut and locking handle are loosened, and the handwheel 54 is turned to drive the clamping screw 52 to rotate, so that the movable top cone 53 moves to a suitable position to fit the size of the spool 10. After adjustment, the locking nut is tightened and further secured by the locking handle, using friction to lock the relative position of the clamping screw 52 and the clamping nut seat 51, preventing loosening. Through mechanical locking, the clamping screw 52 is effectively prevented from loosening due to vibration or external force during the wire feeding process, ensuring that the movable top cone 53 always maintains a stable position.

[0027] In some embodiments, both the first lifting frame 23 and the second lifting frame 33 are C-shaped when viewed from the side projection direction, and both the first lifting frame 23 and the second lifting frame 33 are hollow structures. The lifting frame with the above-mentioned shape has a simple structure and is lightweight, which can reduce the load on the lifting motor 41 when the lifting frame rises or falls; moreover, the C-shaped lifting frame can provide space for the installation of components such as the movable top cone 53 and the fixed top cone 55.

[0028] In some embodiments, a feed ramp 11 is provided in the feeding direction of the frame 1. The feed ramp 11 guides the bobbin 10 smoothly into the unloading structure, improving feeding efficiency. During unloading, the gravity of the feed ramp 11 quickly rolls the bobbin 10 away from the unloading structure.

[0029] In some embodiments, the lower surface of the frame 1 is provided with height-adjustable feet 12. The height of the feet 12 can be flexibly adjusted according to the unevenness of the ground to ensure that the frame 1 is in a horizontal and stable state.

[0030] In some embodiments, the lower surface of the frame 1 is provided with pulleys 13, and the pulleys 13 are equipped with brake pads (which are covered). The pulleys 13 allow the equipment to be easily moved in workshops and other locations, improving the flexibility of equipment use. When the equipment moves to the target position, the brake pads lock the pulleys 13 to prevent the equipment from sliding accidentally, ensuring the stability and reliability of the equipment during the wire laying operation.

[0031] In summary, this utility model, through the transmission design of the synchronous belt 46, the driving pulley 44, and the driven pulley 45, ensures that the first lead screw 21 and the second lead screw 31 rotate synchronously, and that the first lifting frame 23 and the second lifting frame 33 rise and fall synchronously, thus solving the problem of motor synchronization rate deviation and ensuring that the spool 10 rises and falls horizontally. The lifting drive mechanism 4 adopts a combination of gear meshing and synchronous belt 46 transmission, which ensures stable transmission, high power transmission efficiency, and reduces the possibility of spool 10 tilting due to transmission errors.
