Abstract
Description
Technical Field
[0001] This utility model relates to the field of aluminum wire layer winding technology, and more specifically, to an aluminum wire layer winding anti-loosening device. Background Technology
[0002] Aluminum wire is typically stored and transported in layered coils during production and warehousing. To ensure the coils remain structurally stable and prevent loosening during handling, the industry commonly uses nylon or plastic cable ties to repeatedly secure the outer edges. This method utilizes the one-way locking properties of the cable ties to provide initial binding force, and is cost-effective and easy to operate.
[0003] However, this traditional cable tie method has drawbacks. First, when the wire needs to be used, all the cable ties must be cut to release the wire ends, which damages the original fasteners and prevents reuse. Second, after use, it is difficult for operators to manually re-bundle the used wire spools to their initial tightness. Often, the spools are not tightly bound, causing them to loosen and become tangled in subsequent operations, leading to inconvenience for next use and posing certain safety hazards. Utility Model Content
[0004] The purpose of this invention is to address the problems in the prior art by providing a reusable aluminum wire layer winding anti-loosening device that can keep the aluminum wire secure and prevent it from loosening during use.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: This utility model provides an aluminum wire layer winding anti-loosening device, including a winding wheel for setting aluminum wire, side plates are respectively provided on both sides of the winding wheel, and a plurality of mounting parts are provided on the outer periphery of the side plate (20) extending outward to the outer side of the winding wheel (10), and the side plate is rotatably mounted on the rotating shaft of the winding wheel. The end of the mounting part is provided with a groove (23) along its extension direction. A limiting component is provided between the grooves (23) on two adjacent mounting parts of the two sets of side plates (20). The two adjacent mounting parts of the two sets of side plates (20) and the limiting component and the winding wheel (10) enclose a storage space. The size of the storage space is adjustable along the extension direction of the mounting part. The limiting component includes a roller, with a slider rotatably connected to both ends of the roller. The slider is used to slide in the groove. One end of the slider along the sliding direction is connected to a fixing member by several springs. The fixing member is detachably installed on the side plate (20) or the mounting part so that the limiting component abuts against the aluminum wire. At least one of the limiting components also includes a fastening plate, the two ends of which are rotatably connected to the shafts at both ends of the roller.
[0006] Optionally, the fastening plate has an anti-slip surface on the side facing the aluminum wire.
[0007] Optionally, a baffle is provided on the outer side of the slider away from the roller, and the baffle is located outside the side plate.
[0008] Optionally, the fastener includes a fixing plate, the fixing plate being provided with a first fixing hole, and the side plate and / or the mounting portion being provided with a plurality of second fixing holes that match the first fixing hole, the plurality of second fixing holes being distributed along the extension direction of the slide groove; The second fixing hole and the first fixing hole are connected and fixed by screws.
[0009] Optionally, the fastener further includes a retaining plate for connecting the fixing plate. The side plate is provided with a plurality of slots that are positioned opposite the retaining plate. The slots and the second fixing hole are arranged in pairs. The retaining plate is placed in the slots and connected to the end of the spring (33) away from the slider (37).
[0010] The beneficial effects that this utility model can produce include: 1) During the unwinding process, the aluminum wire drags the roller, which drives the entire side plate to rotate relative to the winding wheel via the slider. During this process, the limiting component provides radial, center-pointing clamping force to the wire coil under the action of spring tension. This clamping force is adaptively adjusted as the diameter of the wire coil decreases, ensuring that the wire is always in a uniformly bound state throughout the entire service cycle from full coil to empty coil, avoiding the risk of loosening due to diameter changes.
[0011] 2) When the wire roll needs to be fixed for handling or storage after use, rotate the fastening plate to the position where its surface is in contact with the end face of the wire. The fastening plate is in close contact with the surface of the wire, thereby effectively locking the relative rotation between the side plate and the wire roll. No tools are required, and it can be done by hand without damaging any parts. This allows for unlimited reuse of the device, which is economical and environmentally friendly.

[0015] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of this application. It should be noted that, without conflict, the various features in the embodiments of this application can be combined with each other, and the combined embodiments are still within the protection scope of this application.
[0016] like Figure 1 and Figure 2As shown, the aluminum wire layer winding anti-loosening device provided in this application embodiment includes a take-up reel 10 for mounting aluminum wire. Side plates 20 are respectively provided on both sides of the take-up reel 10. Several mounting portions are provided on the outer periphery of the side plates 20 extending outward to the outer side of the take-up reel 10. The side plates 20 are rotatably mounted on the rotating shaft of the take-up reel 10. A groove 23 is provided at the end of each mounting portion along its extending direction. A limiting component is provided between the grooves 23 on two adjacent mounting portions of two sets of side plates 20, and the two adjacent mounting portions of the two sets of side plates 20 and the limiting component are connected to the take-up reel. A storage space is formed between the wheels 10, and the size of the storage space is adjustable along the extension direction of the mounting part. The limiting component includes a roller 30, with sliders 37 rotatably connected to both ends of the roller 30. The sliders 37 slide within the groove 23, and one end of the slider 37 along the sliding direction is connected to a fixing member via several springs 33. The fixing member is detachably mounted on the side plate 20 or the mounting part so that the limiting component abuts against the aluminum wire. At least one of the limiting components also includes a fastening plate 31, with both ends of the fastening plate 31 rotatably connected to the rotating shafts at both ends of the roller 30. The structure of the springs 33 pulling the sliders 37 and the rollers 30 ensures that the rollers 30 are always in close contact with the surface of the aluminum wire coil. During the wire unwinding and the coil diameter decreasing, the limiting component can adaptively move radially along the groove 23, continuously providing a clamping force pointing towards the center to prevent the wire coil from loosening. By setting the rotatable fastening plate 31, the device has two operating modes. During wire unwinding, the fastening plate 31 retracts, and the rollers 30 roll, resulting in minimal resistance. When securing the wire for transport, the fastening plate 31 is rotated down, its surface contacting the wire, thus locking the relative movement of the side plate 20 and the wire coil, providing extremely strong radial and axial locking force to prevent loosening during transport. The operator can unwind and lock the wire coil by hand, eliminating tedious steps such as cutting and bundling, resulting in extremely high efficiency, and the coil can be reused.
[0017] like Figure 5 As shown, the fastening plate 31 has an anti-slip surface on the side facing the aluminum wire. Providing an anti-slip surface, such as a rubber layer, pattern, or knurling, on the surface of the fastening plate 31 significantly increases its static friction coefficient with the aluminum wire surface. When the equipment vibrates or is impacted, the anti-slip surface effectively prevents relative sliding between the fastening plate 31 and the wire surface, ensuring a locked state.
[0018] like Figure 4 As shown, a baffle 32 is provided on the outer side of the slider 37 away from the roller 30, and the baffle 32 is located on the outside of the side plate 20. This effectively prevents the slider 37 from completely dislodging from the slide groove 23 under the tension of the spring 33 or external impact, improving the safety and reliability of the device. On the other hand, the baffle 32 provides the operator with a convenient point of force application. When it is necessary to move the entire limiting assembly out of the slide groove 23 to load or unload the wire coil, the operator can directly pull the baffle 32 by hand, making the operation more effortless and convenient.
[0019] like Figure 2 As shown in the embodiment of this application, the side plate 20 includes several connecting plates 22, and the mounting part is configured as a connecting plate 22. In this application, three connecting plates 22 are provided, and the connecting plates 22 are arranged radially so that the sliding grooves 23 are respectively disposed on the connecting plates 22. By using a structure of radial connecting plates 22 to form the main body of the side plate 20, instead of a single solid plate, the overall weight of the device can be significantly reduced while ensuring the necessary structural strength, saving material costs and facilitating operation. The connecting plate 22 has a small contact area with the side of the coil, which facilitates rotation relative to the coil.
[0020] like Figure 3 As shown, the fastener includes a fixing plate 34 with a first fixing hole 35. The side plate 20 and / or the mounting portion have several second fixing holes 25 that match the first fixing hole 35. These second fixing holes 25 are distributed along the extending direction of the slide groove 23. The second fixing holes 25 and the first fixing holes 35 are connected and fixed by screws. By providing multiple second fixing holes 25 distributed along the extending direction of the slide groove 23, the fixing plate 34 can be fixed to the side plate 20 at different positions. Users can adjust the initial tension of the spring 33, thereby flexibly adjusting the clamping force of the roller 30 on the wire coil according to the specifications of the wire, thus broadening its applicability.
[0021] Specifically, the fastener also includes a retaining plate 36 connecting the fixing plate 34. The side plate 20 has several slots 24 positioned opposite the retaining plate 36. The slots 24 and the second fixing hole 25 are paired. The retaining plate 36 is placed within the slots 24 and connected to the end of the spring 33 furthest from the slider 37. The fastener is pre-positioned through the cooperation of the retaining plate 36 and the slots 24, temporarily fixing the fastener before tightening the screws, facilitating installation and ensuring accurate alignment of the first fixing hole 35 and the second fixing hole 25. After the retaining plate 36 is embedded in the slots 24, it can bear most of the tension and torque from the spring 33, reducing the burden on the screws to withstand shear forces, making the connection more stable and reliable, and extending the screw's service life. Even if the screws are slightly loose, the cooperation between the slots 24 and the retaining plate 36 prevents the fastener from rotating or shifting, providing double protection.
[0022] The working process of the aluminum wire layer winding anti-loosening device provided in this application embodiment is as follows: During wire feeding, the movement of the aluminum wire drives the roller 30 in contact with it to roll, which in turn drives the entire side plate 20 to rotate synchronously relative to the winding wheel 10 through the slider 37. At this time, each limiting component moves radially adaptively along the slide groove 23 under the tension of the spring 33, so that the roller 30 is always in close contact with the surface of the wire roll and provides continuous radial clamping force, effectively preventing the wire roll from loosening. When the wire feeding is finished and needs to be transported or stored, the operator flips the fastening plate 31 by hand, so that the plate surface with the anti-slip surface presses against the end face of the wire, locking the relative movement between the side plate 20 and the wire roll by friction and interference. The device then changes from dynamic wire feeding mode to static locking mode, firmly fixing the wire roll. When using it again, simply flip the fastening plate 31 back to its original position to restore the wire feeding function. The whole process does not require any tools, is easy to operate, and can be reused repeatedly.
[0023] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
