Description

Technical Field

[0001] This utility model relates to the field of wire stretching machine technology, specifically to a wire stretching machine inlet anti-tangling mechanism. Background Technology

[0002] The anti-winding mechanism for wire feeding in a wire stretching machine is used in the field of metal wire processing. Specifically, it is adapted to the wire feeding stage before the wire stretching process. It is an auxiliary mechanism used in conjunction with components such as the wire feeding wheel and straightening wheel. Its core function is to standardize the wire feeding process after the whole coil of wire is unwound, and to ensure the smoothness of the wire feeding stage in the wire stretching operation. It is a key auxiliary component in the wire stretching machine processing system for optimizing the quality of wire feeding.

[0003] Traditional wire drawing machines lack a design to separate the main coil of the wire roll from the section of wire entering the feed wheel. The drag force generated by the feed wheel during operation directly affects the main coil, causing it to shift and accumulate towards the feed wheel, leading to wire tangling. Furthermore, traditional structures lack components to guide the wire's direction from the side, horizontally, and vertically, resulting in a chaotic wire path after unwinding and potential deviations in the path from the straightening wheel to the feed wheel. Additionally, many components in traditional wire drawing machines are fixed, leading to significant sliding friction when the wire contacts these components. This not only easily scratches the wire surface and damages its quality but also causes wear on the machine's contact surfaces, potentially resulting in discoloration over time. Moreover, the haphazard wire feeding method of traditional wire drawing machines fails to pre-separate tangled or knotted coils before the feed wheel. These problematic coils can compress the main coil, potentially causing the drawing operation to stop and impacting overall efficiency. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides an anti-tangling mechanism for the wire feed of a wire stretching machine to solve the above-mentioned technical problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wire feeding anti-tangling mechanism for a wire stretching machine, comprising: a main frame and a wire feeding wheel, wherein the wire feeding wheel is rotatably disposed on the right side of the main frame, a main spindle is disposed on the right side of the main frame via a bearing with a seat, and a limiting mechanism is disposed between the main spindle and the main frame, and the limiting mechanisms are uniformly disposed on the outside of the main frame; The output end of the limiting mechanism is equipped with a wire guide rod. A wire feeding wheel is rotatably mounted on the top right side of the main frame via a bearing seat. A side guide rod is mounted on the outside of the wire feeding wheel. A horizontal guide rod is rotatably connected to the right side of the wire feeding wheel via a bracket. Vertical guide rods are rotatably connected to both ends of the right side of the main frame via mounting seats. The main spindle is used to hold the entire coil of wire, providing a rotating carrier for uncoiling the wire. The wire guide rod can be adjusted in front and back installation position with the help of the limiting mechanism, which can effectively separate the main coil of the whole roll of wire from the wire section to be fed into the feed wheel, thus preventing the main coil from being pulled and accumulating on it by the feed wheel from the source. Side guide rods can help limit the position of the wire from the side, and together with horizontal and vertical guide rods, they can regulate the direction of the wire after unwinding and prevent the wire from deviating. The vertical guide rods are installed on the inner and outer sides of the wire feeding wheel, which can further constrain the path of the wire from the straightening wheel to the wire feeding wheel and ensure the stability of wire feeding. Moreover, all guide rods can rotate freely and flexibly, which can greatly reduce the sliding friction between the wire and the guide rods during the guiding process and avoid scratches on the surface of the wire.

[0006] Preferably, the limiting mechanism includes a chuck, the inner cavity of which is provided with a square groove, the inner cavity of which is slidably connected with a latch, a spring connecting the latch and the square groove, the inner cavity of the dividing guide rod is provided with a slot, the slot is adapted to the latch, the inner cavity of the spring is slidably connected with a push plate, and the outside of the push plate is rotatably connected with a connecting rod. The other end of the connecting rod is rotatably connected to a pull arm. The working principle of this limiting mechanism is as follows: In its natural state, the spring pushes the latch out of the square slot and into the slot of the wire guide rod, thereby fixing the position of the wire guide rod; when it is necessary to adjust the front and rear position of the wire guide rod according to the wire specifications, the operator pulls the pull arm, which drives the push plate through the connecting rod to compress the spring, causing the latch to retract into the square slot, releasing the limitation on the wire guide rod. At this time, the wire guide rod can be moved to the required position; after releasing the pull arm, the spring resets and pushes the latch to re-engage into the corresponding slot, completing the position locking of the wire guide rod and ensuring the wire splitting effect under different working conditions.

[0007] Preferably, a return mechanism is connected between the pull arm and the branching guide rod, and a handle is provided on the top of the pull arm. The function of the return mechanism is to automatically drive the pull arm back to its initial state after the branching guide rod position is adjusted by pulling the pull arm, eliminating the need for manual pushing by the operator and effectively improving operational convenience. The handle on the top of the pull arm provides the operator with a point of force, making it easy to pull the pull arm, reducing the operational intensity when adjusting the position of the branching guide rod, and improving adjustment efficiency.

[0008] Preferably, the inner cavity of the dividing guide rod is provided with an annular groove, which is slidably connected to the pull arm. This slidable connection between the annular groove and the pull arm precisely limits the movement trajectory of the pull arm, preventing lateral deviation during pulling and ensuring that the pull arm can stably drive the push plate to compress the spring via the connecting rod. Simultaneously, this structure makes the sliding process of the pull arm smoother and reduces adjustment jamming caused by trajectory deviation, ensuring the stable operation of the limiting mechanism.

[0009] Preferably, the top of the latch is designed with a slope, and a wear-resistant pad is provided on the top of the latch. The sloped design of the latch top allows the latch to slide smoothly into the slot when the splitter rod moves to the positioning position, eliminating the need for precise alignment between the slot and the latch by the operator, significantly reducing the difficulty of alignment during splitter rod position adjustment. The wear-resistant pad on the top of the latch enhances the wear resistance of the contact area between the latch and the splitter rod slot, reducing wear during long-term engagement and disengagement, extending the service life of both the latch and the splitter rod, and reducing maintenance costs.

[0010] Preferably, the chuck is externally provided with a flange, which is connected to the outside of the main frame by bolts. This flange and bolt connection ensures a secure and reliable connection between the chuck and the main frame, capable of withstanding the forces generated during the adjustment of the wire guide rod and the pulling of the wire, preventing the limiting mechanism from loosening under stress and affecting the wire separating effect. Simultaneously, the bolt connection facilitates the disassembly of the limiting mechanism later; when internal components of the limiting mechanism malfunction, they can be quickly disassembled for repair or replacement, improving maintenance convenience.

[0011] Compared with the prior art, this utility model provides an anti-tangling mechanism for the wire feed of a wire stretcher, which has the following advantages: This wire drawing machine's anti-tangling mechanism effectively separates the main coil of the wire roll from the feed section before it enters the feed wheel using a wire guide rod. This prevents the main coil from being pulled and accumulating on the feed wheel, thus solving the problem of easy tangling in traditional wire feeding methods. Side guide rods assist in defining the wire position from the side, working in conjunction with horizontal and vertical guide rods to regulate the wire's direction after unwinding. The vertical guide rods further constrain the wire's path from the straightening wheel to the feed wheel, ensuring stable wire feeding and preventing wire deviation. All guide rods can rotate freely and flexibly, significantly reducing sliding friction between the wire and guide rods during the guiding process, preventing scratches on the wire surface and protecting the wire's appearance and quality. Simultaneously, this mechanism changes the messy wire feeding method of traditional wire drawing machines, separating tangled or knotted wire rolls before the feed wheel, preventing them from being squeezed and tangled with the main coil, improving the order of wire feeding and the overall efficiency of the wire drawing operation.

[0014] The technical solutions of the present utility model 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 utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] This utility model provides a technical solution, please refer to [link / reference]. Figure 1 and Figure 2 The anti-tangling mechanism for the wire feeding of the wire stretching machine includes: a main frame 1 and a wire feeding wheel 2. The wire feeding wheel 2 is rotatably mounted on the right side of the main frame 1. A main spindle 7 is mounted on the right side of the main frame 1 via a bearing seat, and a limiting mechanism 8 is provided between the main spindle 7 and the main frame 1. The limiting mechanisms 8 are evenly distributed on the outside of the main frame 1. The output end of the limiting mechanism 8 is equipped with a wire guide rod 4. A wire feed wheel 2 is rotatably mounted on the top right side of the main frame 1 via a bearing seat. A side guide rod 5 is mounted on the outside of the wire feed wheel 2. A horizontal guide rod 6 is rotatably connected to the right side of the wire feed wheel 2 via a bracket. Vertical guide rods 3 are rotatably connected to both ends of the right side of the main frame 1 via mounting seats. The main spindle 7 is used to hang the entire roll of wire, providing a rotating carrier for uncoiling the wire. The wire separating guide rod 4 can be adjusted in front and back installation position with the help of the limiting mechanism 8, which can effectively separate the main coil of the whole roll of wire from the wire section to be fed into the wire feeding wheel 2, and prevent the main coil from being dragged and piled up by the wire feeding wheel 2 from the source. The wire separating guide rod 4 includes a rod body, and the bottom of the rod body is provided with a seated bearing. Please see Figure 3 and Figure 4 The side guide rod 5 can help limit the position of the wire from the side, and together with the horizontal guide rod 6 and the vertical guide rod 3, it can regulate the direction of the wire after unwinding and prevent the wire from deviating. The vertical guide rod 3 is installed on the inner and outer sides of the wire feeding wheel 2, which can further constrain the path of the wire from the straightening wheel to the wire feeding wheel 2 and ensure the stability of wire feeding. Moreover, all guide rods can rotate freely and flexibly, which can greatly reduce the sliding friction between the wire and the guide rod during the guiding process and avoid the wire surface being scratched.

[0016] The limiting mechanism 8 includes a chuck 81, with square grooves 82 in the inner cavity of the chuck 81. A latch 83 is slidably connected to the inner cavity of the square groove 82. A spring 84 is connected between the latch 83 and the square groove 82. A slot is opened in the inner cavity of the dividing guide rod 4, which is adapted to the latch 83. A push plate 85 is slidably connected to the inner cavity of the spring 84. A connecting rod 86 is rotatably connected to the outside of the push plate 85. The other end of the connecting rod 86 is rotatably connected to the pull arm 87. The working principle of the limiting mechanism 8 is as follows: In its natural state, the spring 84 pushes the latch 83 out of the square groove 82 and into the slot of the wire guide rod 4, thereby fixing the position of the wire guide rod 4; when it is necessary to adjust the front and rear position of the wire guide rod 4 according to the wire specifications, the operator pulls the pull arm 87, which drives the push plate 85 through the connecting rod 86 to compress the spring 84, causing the latch 83 to retract into the square groove 82, releasing the limitation on the wire guide rod 4. At this time, the wire guide rod 4 can be moved to the required position; after releasing the pull arm 87, the spring 84 resets and pushes the latch 83 into the corresponding slot again, completing the position locking of the wire guide rod 4 and ensuring the wire splitting effect under different working conditions.

[0017] A return mechanism connects the pull arm 87 to the branch guide rod 4, and a handle is provided on the top of the pull arm 87. The function of the return mechanism is to automatically return the pull arm 87 to its initial state after the branch guide rod 4 is adjusted by pulling the pull arm 87, eliminating the need for manual pushing by the operator and effectively improving operational convenience. The handle on the top of the pull arm 87 provides a point of leverage for the operator, making it easy to pull the pull arm 87, reducing the operational effort required to adjust the position of the branch guide rod 4, and improving adjustment efficiency.

[0018] The inner cavity of the dividing guide rod 4 has an annular groove, which is slidably connected to the pull arm 87. The sliding connection structure between the annular groove and the pull arm 87 can precisely limit the movement trajectory of the pull arm 87, prevent the pull arm 87 from shifting laterally during the pulling process, and ensure that the pull arm 87 can stably drive the push plate 85 to compress the spring 84 through the connecting rod 86. At the same time, this structure can make the sliding process of the pull arm 87 smoother and reduce the adjustment jamming caused by trajectory deviation, thus ensuring the stable operation of the limit mechanism 8.

[0019] The top of the latch 83 is designed with a slope, and a wear-resistant pad is provided on the top of the latch 83. The slope design of the top of the latch 83 allows the latch 83 to slide smoothly into the slot when the splitter rod 4 is moved to the positioning position, eliminating the need for operators to precisely align the slot and the latch 83, greatly reducing the difficulty of alignment when adjusting the position of the splitter rod 4; the wear-resistant pad on the top of the latch 83 enhances the wear resistance of the contact area between the latch 83 and the slot of the splitter rod 4, reducing wear during long-term engagement and disengagement, extending the service life of the latch 83 and the splitter rod 4, and reducing maintenance costs.

[0020] The chuck 81 is externally fitted with a flange, which is bolted to the outside of the main frame 1. This flange and bolt connection ensures a secure and reliable connection between the chuck 81 and the main frame 1, capable of withstanding the forces generated during the adjustment of the wire guide rod 4 and the pulling of the wire, preventing the limiting mechanism 8 from loosening under stress and affecting the wire separating effect. Simultaneously, the bolt connection facilitates the later disassembly of the limiting mechanism 8; when internal components of the limiting mechanism 8 malfunction, they can be quickly disassembled for repair or replacement, improving maintenance convenience.
