Description

Technical Field

[0001] This utility model relates to the technical field of winding and coiling devices, specifically to a device for winding and coiling nylon yarn. Background Technology

[0002] In the production and processing of nylon filament, winding the nylon filament into coils is one of the important processes. Existing nylon filament winding and coiling equipment usually has a fixed installation shaft length for the winding rod. This means that when facing the need to wind nylon filaments of different specifications and lengths, different winding equipment needs to be changed. This not only increases equipment costs, but also reduces production efficiency due to frequent equipment changes. The operation is cumbersome and it is difficult to meet diverse production needs. Utility Model Content

[0003] This utility model mainly provides a device for winding nylon yarn into coils. By setting a distance adjustment mechanism, the distance between the fixed frame and the mounting frame on the right side can be adjusted, thereby enabling the detachable connection of winding rods with different shaft lengths, realizing the winding of nylon yarns of different specifications and lengths, and improving the versatility and production efficiency of the equipment.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A nylon filament winding device includes two mounting frames and multiple winding rods. A distance adjustment mechanism is mounted on the left mounting frame, and a fixed frame is mounted on the distance adjustment mechanism. The fixed frame adjusts its distance from the right mounting frame via the distance adjustment mechanism. A first turntable is rotatably connected to the fixed frame, and a second turntable is rotatably connected to the left mounting frame. A drive mechanism for rotating the first turntable is mounted on the fixed frame. Either winding rod is detachably connected between the first and second turntables. The drive mechanism can employ any existing structure, as long as it can rotate the second turntable, thereby driving the detachably connected winding rod between the first and second turntables to wind the nylon filament. Specifically, a multi-segment telescopic support rod is provided between the fixed frame and the left mounting frame. Working principle: The distance between the fixed frame and the right-side mounting frame is adjusted by a distance adjustment mechanism to accommodate winding screws of different shaft lengths. The two ends of the winding screw are detachably connected to the first and second turntables respectively. The drive mechanism drives the second turntable to rotate, thereby causing the winding screw to rotate and achieve nylon yarn winding. This structure allows for flexible replacement of winding screws with different shaft lengths to meet the winding needs of various specifications of nylon yarn, improving equipment versatility, reducing equipment procurement costs, shortening equipment changeover time, and increasing production efficiency.

[0006] Furthermore, the distance adjustment mechanism includes a connecting guide rod fixedly connected between the two mounting brackets, a connecting screw rotatably connected between the two mounting brackets, and a first motor mounted on either side of the mounting bracket to drive the connecting screw to rotate; the fixed bracket is threadedly connected to the connecting screw and slidably connected to the connecting guide rod. Specifically, the first motor can be mounted on the corresponding mounting bracket in any existing manner. Working principle: When the first motor is energized, it drives the connecting screw to rotate. Because the connecting guide rod restricts the rotational freedom of the fixed bracket, the fixed bracket can only move linearly along the axial direction of the connecting screw and the guiding direction of the connecting guide rod, thereby achieving precise adjustment of the distance between the fixed bracket and the right mounting bracket. Using this structure, through the cooperation of the motor, screw, and guide rod, automated distance adjustment is achieved. It is easy to operate, has high adjustment accuracy, is more efficient and stable, and can quickly adapt to threaded screws of different shaft lengths, improving the ease of use of the equipment.

[0007] Furthermore, the device includes at least two connecting guide rods, which are symmetrically arranged on both sides of the connecting screw. This structure provides multiple supports for the mounting frame, enhancing its stability during movement and making the overall structure, including the mounting frame, more stable.

[0008] Furthermore, the first and second turntables have identical structures. The first turntable includes a disc body with connecting protrusions. Each connecting protrusion has a rectangular connecting groove. Both ends of the winding rod have rectangular connecting blocks that mate with the rectangular connecting grooves. The connecting protrusions are detachably connected to the rectangular connecting blocks located within the rectangular connecting grooves via bolts. Working principle: First, rotate and adjust the rectangular connecting grooves of the first and second turntables so that their openings are vertically downwards. When installing the winding rod, align and insert the rectangular connecting blocks at both ends of the winding rod into the adjusted rectangular connecting grooves of the first and second turntables. Tighten the bolts through the corresponding screw holes on the connecting protrusions and rectangular connecting blocks to secure the winding rod firmly to the turntables. For disassembly, unscrew the bolts to remove the winding rod. This structure offers a simple connection method, a secure and reliable connection, and convenient and quick disassembly. It allows for rapid replacement of winding rods with different shaft lengths to meet the requirements of different nylon yarn winding specifications, reducing equipment adjustment time and improving production efficiency.

[0009] Furthermore, the system also includes a linear displacement module disposed between the two mounting frames. The linear displacement module is equipped with a lifting mechanism, and two V-shaped supports are arranged parallel to each other on the lifting mechanism. Each V-shaped support has a symmetrically arranged cooperating shaft. The lifting mechanism can be any existing technology, as long as it can move the two V-shaped supports up and down, thereby raising the empty lead screw or lowering the wound lead screw. The cooperating shaft is rotatably connected to the V-shaped supports, facilitating the adjustment of the position of the empty lead screw and ensuring alignment and connection between the lead screw and the first and second turntables. Working principle: The linear displacement module can drive the lifting mechanism to move along a straight line between the mounting frames. The lifting mechanism can adjust the height of the V-shaped supports. By adjusting the linear displacement module and the lifting mechanism, the two V-shaped supports are always positioned in the optimal support position for the lead screw during production, i.e., the symmetrical plane of the two V-shaped supports and the center plane of the lead screw are on the same plane. Meanwhile, if any existing conveying mechanism is placed on both sides of the linear displacement module, the empty wire winding rod moves to the V-shaped bracket via the conveying mechanism, falling onto the V-shaped bracket through the installation gap between the two conveying mechanisms. The lifting mechanism then drives the V-shaped bracket to load the wire. Next, the wire winding rod coils nylon yarn, and the lifting mechanism again raises the V-shaped bracket to receive the material, causing the coiled nylon yarn to descend. Because the diameter of the wire winding rod increases after the nylon yarn is coiled, it will not fall through the gap between the two conveying mechanisms onto the V-shaped bracket; instead, it will be moved by the conveying mechanism. This structure facilitates the loading and unloading of the wire winding rod and the adjustment of the V-shaped bracket's position via the linear displacement module.

[0010] Beneficial effects: This structure allows for flexible replacement of winding rods with different shaft lengths to meet the winding needs of various specifications of nylon yarn, improves equipment versatility, reduces equipment procurement costs, shortens equipment replacement time, and enhances production efficiency.
