Description

Technical Field

[0001] This utility model relates to the field of unwinding equipment technology, and in particular to an wire unwinding frame. Background Technology

[0002] Wire unwinding racks are devices used in wire production to support and unwind wire spools. Traditional wire unwinding racks typically use a long threaded rod as a fixing structure, with a nut clamping the spool on one side of the rod. To accommodate spools of different widths, the threaded rod is designed to be long, but the nut's diameter is usually larger than the spool's inner diameter. Therefore, when replacing a spool after each unwinding, the nut must be completely unscrewed from the threaded rod to remove the old spool and install the new one. This process is particularly time-consuming for narrower spools, as the nut requires many turns to fully disengage or clamp, reducing production efficiency. Furthermore, the frequent disassembly and installation of the nut increases the labor intensity for workers, impacting overall operational efficiency. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a wire unwinding rack that facilitates the replacement of wire spools and improves production efficiency.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A wire unwinding rack, comprising:

[0006] The fixed rod has a smooth section on the left and a threaded section on the right.

[0007] A left fastening structure is provided on the left side of the fixing rod for fixing the left end of the wire reel spool;

[0008] A right-hand fastening structure is provided on the threaded section of the fixing rod for fixing the right side end of the wire reel cassette. The right-hand fastening structure includes a tapered structure provided on the fixing rod, an expansion structure slidably connected to the tapered structure, a locking structure provided on the right side of the expansion structure, and a counterweight block inserted into the locking structure. The locking structure is threadedly connected to the threaded section of the fixing rod. The counterweight block can drive the locking structure to rotate, causing the locking structure to push the expansion structure to the left. The expansion structure can slide relative to the tapered structure and expand radially outward. The outer wall of the expansion structure can abut against the inner wall of the wire reel cassette.

[0009] According to some embodiments of the present invention, the right side of the tapered structure has a first tapered portion that gradually narrows from left to right, and the expansion structure includes a first fixing portion sleeved on the fixing rod and a plurality of abutting portions disposed on the left side of the first fixing portion, the abutting portions being distributed circumferentially along the first fixing portion.

[0010] According to some embodiments of the present invention, the inner sidewall of the abutting part is a tapered surface that matches the shape of the outer sidewall of the first tapered part, and the right end of the abutting part is slidably connected to the first fixing part.

[0011] According to some embodiments of the present invention, the right end of the abutment portion has a T-shaped sliding protrusion arranged radially along the first fixing portion, and the left side of the first fixing portion is provided with a T-shaped sliding groove that matches and slides with the sliding protrusion.

[0012] According to some embodiments of the present invention, the expansion structure further includes a return spring sleeved on the outer periphery of each of the abutment portions, and the outer wall of the abutment portion is provided with a groove for accommodating the return spring.

[0015] According to some embodiments of the present invention, the counterweight includes a second fixing part for sleeved on the outside of the fixing rod, a counterweight part connected to the outer wall of the second fixing part, and a plurality of snap-fit ​​blocks disposed on the left side of the second fixing part. The right side wall of the locking structure is provided with a plurality of snap-fit ​​grooves for matching and inserting with the snap-fit ​​blocks.

[0016] According to some embodiments of the present invention, each of the snap-fit ​​grooves is distributed circumferentially along the central axis of the locking structure.

[0017] According to some embodiments of the present invention, the left fastening structure includes a third fixing part fixed to the left end of the fixing rod and a second tapered part disposed on the right side of the third fixing part for abutting against the inner hole of the wire reel drum, the second tapered part gradually narrowing from left to right.

[0027] 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.

[0028] 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.

[0029] 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.

[0030] An embodiment of this utility model provides a wire unwinding rack, such as... Figure 1-7 As shown, it includes:

[0031] Fixed rod 1, with a smooth section 11 on the left and a threaded section 12 on the right;

[0032] Left fastening structure 2 is located on the left side of fixing rod 1 and is used to fix the left end of the wire reel drum;

[0033] The right fastening structure 3 is set on the threaded section 12 of the fixing rod 1 and is used to fix the right end of the wire reel drum. The right fastening structure 3 includes a conical structure 301 set on the fixing rod 1, an expansion structure 302 slidably connected to the conical structure 301, a locking structure 303 set on the right side of the expansion structure 302, and a counterweight 304 inserted into the locking structure 303. The locking structure 303 is threadedly connected to the threaded section 12 of the fixing rod 1. The counterweight 304 can drive the locking structure 303 to rotate, so that the locking structure 303 pushes the expansion structure 302 to the left. The expansion structure 302 can slide relative to the conical structure 301 and expand radially outward at the same time. The outer wall of the expansion structure 302 can abut against the inner wall of the wire reel drum.

[0034] The design of the fixed rod 1, with a smooth section 11 on the left and a threaded section 12 on the right, allows the fixed rod 1 to provide stable support while also enabling precise fixing and adjustment with the locking structure 303 via the threaded section 12. This eliminates the need for a continuous thread, reducing processing costs and allowing it to accommodate wire spools of varying widths. The left fastening structure 2 is located on the left side of the fixed rod 1 and is used to fix the left end of the wire spool. This structure is fixed and does not move, and it works in conjunction with the right fastening structure 3 to clamp the wire spool, ensuring stability during unwinding. The right fastening structure 3 includes a conical structure 301, an expansion structure 302, a locking structure 303, and a counterweight 304. The conical surface of the conical structure 301 allows the expansion structure 302 to gradually expand radially outward along the outer wall of the conical shape as it moves to the left, thus tightly abutting against the inner wall of the wire spool and providing strong friction to prevent slippage during unwinding. The conical surface characteristic allows for precise adjustment of the radial expansion distance, accommodating a wider range of wire spools with different inner diameters.

[0035] The counterweight 304 drives the locking structure 303 to rotate. The locking structure 303 is threadedly connected to the threaded section 12 of the fixed rod 1, which can stably press the right side wall of the expansion structure 302 to the left. The expansion structure 302 is not threadedly connected to the fixed rod 1. It can be pushed by the locking structure 303 without rotating, which facilitates the stable expansion of the expansion structure 302. The counterweight 304 drives the wire spool to rotate and unwind on the fixed rod 1 without power through gravity. The diameter of the counterweight 304 can be larger than the inner diameter of the wire spool, while the diameter of the locking structure 303 is smaller than the inner diameter of the wire spool. At the same time, the counterweight 304 is inserted into the locking structure 303 and is not threadedly connected to the fixed rod 1. This means that when changing the wire spool, it is only necessary to pull out the counterweight 304 and the locking structure 303, and the wire spool can be slid laterally out of the fixed rod 1 without the need for long-term threaded rotation and disassembly. This enables quick replacement of the wire spool and improves production efficiency.

[0036] In some embodiments, such as Figure 1-3 As shown, the tapered structure 301 has a first tapered portion 305 that gradually narrows from left to right on the right side. The expansion structure 302 includes a first fixing portion 306 sleeved on the fixing rod 1 and a plurality of abutting portions 307 disposed on the left side of the first fixing portion 306. The abutting portions 307 are distributed circumferentially along the first fixing portion 306.

[0037] The first tapered portion 305, which gradually narrows from left to right, allows the expansion structure 302 to expand radially as it moves to the left, adapting to wire reels of different diameters. The radially distributed abutment portions 307 achieve uniform clamping, enhancing the stability and reliability of the clamping. The expansion structure 302 can be a slider structure that slides relative to the first tapered portion 305, an open tapered sleeve, an elastic flap, or other structures capable of expansion and clamping. The first fixing portion 306 is used to fix each abutment portion 307, and the locking structure 303 pushes all abutment portions 307 simultaneously by pushing the right side wall of the first fixing portion 306.

[0038] Furthermore, such as Figure 4-5 As shown, the inner wall of the abutment portion 307 is a tapered surface 308 that matches the shape of the outer wall of the first tapered portion 305, and the right end of the abutment portion 307 is slidably connected to the first fixing portion 306.

[0039] The tapered surface 308 allows the abutment portion 307 to achieve stable and precise radial expansion under the guidance of the first tapered portion 305, thereby ensuring that the abutment portion 307 can tightly and evenly abut against the inner wall of the winding drum, providing strong friction and preventing the winding drum from slipping during unwinding. The sliding connection between the abutment portion 307 and the first fixing portion 306 allows the outer wall of the abutment portion 307 to completely abut against the inner wall of the winding drum, providing a tighter abutment against the inner wall of the winding drum compared to a clamshell-like fixing connection.

[0040] Furthermore, such as Figure 3-4 As shown, the right end of the abutment portion 307 has a T-shaped sliding protrusion 309 arranged radially along the first fixing portion 306, and the left side of the first fixing portion 306 has a T-shaped sliding groove 310 that matches and slides with the sliding protrusion 309.

[0041] The T-shaped sliding mechanism is stable and reliable, preventing detachment and simplifying processing. The structure of the sliding protrusion 309 and the sliding groove 310 ensures stable sliding on the first fixed part 306 when each abutment part 307 expands radially, ensuring that each abutment part 307 moves radially along the first fixed part 306, while preventing lateral movement during the sliding process, thus enhancing the stability and durability of the structure.

[0042] Furthermore, such as Figure 1-3 As shown, the expansion structure 302 also includes a return spring 311 sleeved on the outer periphery of each abutment portion 307, and a groove 312 for accommodating the return spring 311 is provided on the outer wall of the abutment portion 307.

[0043] The return spring 311 enables the expansion structure 302 to automatically reset after the pressure is released, simplifying the operation process and improving the efficiency of use. The return spring 311 is fully sleeved in the groove 312 on the outer periphery of each abutment part 307. When the expansion structure 302 expands radially, the return spring 311 is stretched. When the wire spool is replaced, the return spring 311 can immediately retract after the locking structure 303 is loosened to release the clamping on the inner hole of the wire spool.

[0044] Furthermore, such as Figure 1-3 As shown, the left end of the tapered structure 301 abuts against the right end of the smooth section 11 of the fixing rod 1, and the tapered structure 301 is threadedly connected to the fixing rod 1.

[0045] The left end of the tapered structure 301 abuts against the right end of the smooth section 11 of the fixing rod 1, preventing it from moving further to the left and ensuring the stable fixation of the tapered structure 301. At the same time, it allows the position of the tapered structure 301 to be adjusted by thread. The specific clamping position can be adjusted to the right by rotating the tapered structure 301. The tapered structure 301 may also include a detachable limiting block, which is engaged at the right end of the smooth section 11 so that the left end of the tapered structure 301 remains abutting against the right end of the smooth section 11 of the fixing rod 1, in order to accommodate wire reels of different widths and improve the adaptability and flexibility of the structure.

[0046] Furthermore, such as Figure 1 , 6 As shown, the diameter of the locking structure 303 is smaller than the diameter of the inner hole of the wire reel, and the left side wall of the locking structure 303 can abut against the right side wall of the first fixing part 306.

[0047] The locking structure 303 is threadedly connected to the fixing rod 1, ensuring that the locking structure 303 can move stably to the left and press against the right side wall of the expansion structure 302, preventing slippage. The diameter of the locking structure 303 is smaller than the inner diameter of the wire spool, allowing the wire spool to be pulled out directly when replacing it without getting stuck. This eliminates the need to completely unscrew the locking structure 303, improving the efficiency of wire spool replacement.

[0048] Furthermore, such as Figure 1 , 6 As shown in Figures 7 and 8, the counterweight 304 includes a second fixing part 313 for being sleeved on the outside of the fixing rod 1, a counterweight part 314 connected to the outer wall of the second fixing part 313, and a plurality of snap-fit ​​blocks 315 disposed on the left side of the second fixing part 313. The right side wall of the locking structure 303 is provided with a plurality of snap-fit ​​grooves 316 for being inserted into the snap-fit ​​blocks 315.

[0049] The counterweight 304 is secured to the locking structure 303 by multiple snap-fit ​​blocks 315 that engage with the snap-fit ​​grooves 316 of the locking structure 303. This secures the counterweight 304 to the wire reel, simplifying its installation and removal. Gravity causes the wire reel to rotate without power on the fixing rod 1. Simultaneously, the thread direction matches the rotation direction of the wire reel, allowing the counterweight 304 to continuously tighten the locking structure 303 to the left while simultaneously rotating the fixing rod 1. This counterweight also acts as a wrench for the locking structure 303, enhancing the stability of the wire reel.

[0050] Furthermore, such as Figure 6-7 As shown, each snap-fit ​​groove 316 is distributed circumferentially along the central axis of the locking structure 303.

[0051] The locking blocks 315 are evenly distributed around the locking structure 303, ensuring stable insertion of the counterweight block 304. Simultaneously, the evenly distributed locking grooves 316 improve the structure's balance and stability. Specifically, the locking grooves 316 and locking blocks can be trapezoidal or other shapes to enhance connection stability.

[0052] In some embodiments, such as Figure 1 As shown, the left fastening structure 2 includes a third fixing part 201 fixed to the left end of the fixing rod 1 and a second tapered part 202 provided on the right side of the third fixing part 201 for abutting against the inner hole of the wire reel. The second tapered part 202 gradually narrows from left to right.

[0053] The left fastening structure 2 can tightly abut against the inner wall of the wire reel, providing strong friction to prevent the wire reel from sliding during unwinding. At the same time, the design of the second tapered part 202 enhances the adaptability and stability of the left fastening structure 2, and can adapt to the inner hole of various wire reels.

Therefore, those skilled in the art should understand that the foregoing description of various embodiments of the present invention is for illustrative purposes only, and not intended to limit the present invention as defined by the appended claims and their equivalents.
