Description

Technical Field

[0001] This utility model relates to the technical field of wire take-up clamping equipment, and in particular to a dual-power wire take-up clamping device. Background Technology

[0002] Dual-power take-up frames are winding devices used in continuous production or processing equipment for wires, cables, and metal wires. They are characterized by employing dual-power drive systems for separate control, enabling more efficient and precise take-up operations. Common take-up frame clamping devices typically use a single-sided drive structure, which is prone to clamping misalignment, causing one-sided wear or slippage of the wire. This is especially problematic for high-precision wires (such as optical fibers and submarine cables), where the risk of damage is high. Furthermore, their open structure makes it difficult to prevent dust and moisture intrusion, leading to motor corrosion, transmission component jamming, and significantly shortened equipment lifespan in mining and marine environments. Frequent manual adjustments to the clamp spacing, cleaning of filters, and replacement of seals are also required, disrupting continuous production and failing to meet the high reliability requirements under harsh working conditions. Therefore, a dual-power take-up frame clamping device is urgently needed. Utility Model Content

[0003] The purpose of this utility model is to address the deficiencies in the existing technology by proposing a dual-power take-up clamping device.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A dual-power take-up clamping device includes:

[0006] A synchronous drive mechanism, comprising a servo motor, wherein the servo motor drives symmetrically distributed grippers via a lead screw to clamp and release the wire.

[0007] The clamping module includes an elastic buffer layer disposed on the surface of the gripper, and automatically adapts to changes in wire diameter through a wedge-shaped slider structure;

[0008] The drive protection mechanism includes a sealed housing that encloses the clamping mechanism, a centrifugal fan assembly coaxially driven by the take-up frame spindle, a filter channel located at the top, and a pressure relief port located at the bottom, forming a continuous positive pressure airflow that blocks external pollutants.

[0009] Furthermore, the output shaft of the servo motor is connected to the lead screw, the axis of the lead screw is perpendicular to the winding direction, and the rotational speed of the servo motor is synchronized in real time through a closed-loop feedback signal.

[0010] Furthermore, the wedge-shaped slider structure includes an inclined contact surface, and the gripper base is provided with a limiting guide post to constrain lateral offset;

[0011] The surface of the elastic buffer layer is provided with anti-slip texture, and its compression deformation is adaptively adjusted according to the clamping force.

[0012] Furthermore, the filter channel includes several filter structures, the pressure relief port has a spiral angle, and the bottom end of the pressure relief port is provided with a one-way valve that cooperates with it.

[0013] Furthermore, the sealing housing has an annular guide ring on the top inner wall and a spiral guide groove on the bottom;

[0014] The bottom of the sealed housing is provided with a collection pipe that cooperates with the spiral guide groove.

[0015] Furthermore, a scraper is provided below the filter structure, and the scraper has serrated edges to achieve periodic dust removal.

[0016] Furthermore, a disassembly cover is provided on one side of the sealed housing. The disassembly cover is provided with a magnetic ring and an electromagnet that cooperates with the sealed housing. When energized, the disassembly cover is locked to the electromagnet. When the power is turned off, it can be manually separated.

[0017] Furthermore, the gripper allows the wire to float axially in the clamping state, and the floating range is constrained by the limiting guide post through the adjusting block. When the clamping force exceeds the limit, the power transmission is automatically cut off.

[0018] Compared with existing technologies, the beneficial effects of this utility model are as follows:

[0019] The servo motor synchronously drives the gripper to close, and the wedge-shaped slider structure automatically adapts to changes in wire diameter, creating an anti-contamination space. This achieves a synergistic improvement in clamping accuracy, environmental tolerance, and ease of maintenance. During this process, the inclined contact surface of the wedge-shaped slider structure and the compression deformation of the elastic buffer layer are linked, automatically accommodating different wire diameter ranges. The anti-slip texture prevents the wire from slipping, ensuring zero damage during clamping. The gradient filtration structure combined with the centrifugal fan creates a continuous positive pressure airflow, blocking dust / moisture, reducing environmental pollution, lowering the frequency of manual cleaning, and ensuring the safety of the equipment and operators.

[0029] Reference Figure 1-5 The dual-power take-up clamping device includes:

[0030] Synchronous drive mechanism 1, the synchronous drive mechanism includes symmetrically arranged servo motors 2, the servo motors 2 push the symmetrically distributed grippers 4 through the lead screw 3 to clamp and release the wire;

[0031] The clamping module 5 includes an elastic buffer layer 6 disposed on the surface of the gripper 4, and automatically adapts to changes in wire diameter through a wedge-shaped slider structure 7;

[0032] The drive protection mechanism 8 includes a sealed housing 9 enclosing the clamping mechanism, a centrifugal fan assembly 10 coaxially driven by the main shaft of the take-up frame, a filter channel 11 located at the top, and a pressure relief port 12 located at the bottom, forming a continuous positive pressure airflow that blocks external pollutants. In one specific embodiment, the synchronous drive mechanism 1 includes a servo motor 2 symmetrically mounted on both sides of the take-up frame, which pushes the upper and lower grippers 4 to move towards each other through a lead screw 3. The servo motor 2 drives the lead screw 3 to push the grippers 4 to close. An elastic buffer layer 6 is attached to the surface of the grippers 4, which flexibly contacts the wire. The wedge-shaped slider structure 7 automatically adjusts the gripper spacing according to the change in wire diameter. The centrifugal fan assembly 10 is driven by the main shaft. External air enters through the top filter channel 11 and is discharged through the bottom pressure relief port 12. When the main shaft rotates, the centrifugal fan assembly 10 draws in filtered air, forming a positive pressure in the cavity, and dust / moisture is blocked outside the cavity.

[0033] The output shaft of the servo motor 2 is connected to the lead screw 3 via a synchronous belt. The axes of the lead screws 3 on both sides are perpendicular to the winding direction, and the speed of the servo motor 2 is synchronized in real time through a closed-loop feedback signal. In one specific implementation, the output shaft of the servo motor 2 is connected to the lead screw 3 via a synchronous belt. The lead screws 3 on both sides are parallel to the direction of movement of the gripper. The servo motor 2 has a built-in encoder to monitor the speed in real time and adjust the deviation through a PLC. The synchronous belt transmits power to the lead screw 3, converting the rotational motion into linear motion of the gripper 4. The closed-loop feedback ensures that the grippers 4 on both sides close synchronously.

[0034] The wedge-shaped slider structure 7 includes an inclined contact surface 15, and the gripper base is provided with a limiting guide post 16 to constrain lateral offset.

[0035] The surface of the elastic buffer layer 6 is provided with anti-slip texture, and its compression deformation is adaptively adjusted with the clamping force. In a specific implementation, when the wire diameter changes, the contact surface 15 of the wedge-shaped slider structure 7 slides, the distance between the grippers 4 is adaptively adjusted, and the limiting guide post 16 prevents the grippers 4 from shifting laterally.

[0036] The filter channel 11 includes several filter structures 18. The pressure relief port 12 has a spiral angle. The bottom end of the pressure relief port 12 is provided with a one-way valve that cooperates with it. In a specific embodiment, the filter channel 11 is provided with a multi-layer filter structure 18, including a metal mesh and an activated carbon layer. The pressure relief port 12 is involute and a one-way valve is installed at the bottom. External air enters the cavity after being purified step by step through the filter structure 18. The high-pressure airflow is discharged from the pressure relief port 12. The one-way valve prevents external gas from flowing back in.

[0037] The inner wall of the sealing housing 9 is provided with an annular guide ring 20, and the bottom is provided with a spiral guide groove 21;

[0038] The bottom of the sealed housing 9 is provided with a collection pipe 22 that cooperates with the spiral guide groove 21. In a specific embodiment, the inner wall of the cavity is provided with an annular guide ring 20 and the bottom is provided with a spiral guide groove 21. The collection pipe 22 is connected to the end of the spiral guide groove 21 and connected to a water storage box. The centrifugal fan group 10 throws out air, the annular guide ring 20 guides the airflow to diffuse downward, the spiral guide groove 21 accelerates the airflow to flow towards the pressure relief port 12, and the condensate is discharged through the collection pipe 22.

[0039] A scraper 14 is provided below the filter structure 18. The scraper 14 is linked to the main shaft of the take-up frame via a connecting rod. The scraper 14 has a serrated edge to achieve periodic dust removal. In one specific embodiment, the scraper 14 is connected to the main shaft via a connecting rod, and the serrated edge is attached to the surface of the filter structure 18. An eccentric wheel is provided at the end of the connecting rod, which drives the scraper 14 to reciprocate as the main shaft rotates. The rotation of the main shaft causes the connecting rod to drive the scraper 14 to scrape the surface of the filter structure 18, and the serrated edge peels off the adhering dust to avoid filter clogging.

[0040] A disassembly cover plate 17 is provided on one side of the sealed housing 9. The disassembly cover plate 17 is provided with a magnetic ring 19 and an electromagnet that cooperates with the sealed housing 9. When energized, the disassembly cover plate 17 is locked with the electromagnet. When de-energized, it can be manually separated. In one specific embodiment, a permanent magnet ring is embedded in the disassembly cover plate 17, and an electromagnet is provided at the cavity opening. When energized, the electromagnet and the magnetic ring 19 are attracted and locked by opposite poles. During normal operation, the electromagnet is energized to seal the cover plate 27. When de-energized, the magnetic force disappears, and the cover plate 27 can be manually lifted for disassembly and maintenance.

[0041] The gripper 4 allows the wire to float axially in the clamping state. The floating range is constrained by the limiting guide post 16 through the adjusting block 13. When the clamping force exceeds the limit, the power transmission is automatically cut off. In a specific implementation, the limiting guide post 16 sets the floating range through the adjusting block 13. When the wire is retracted or extended, the gripper 4 floats slightly along the limiting guide post 16 to avoid hard pulling. In case of overload, the clutch disengages to protect the servo motor 2 and the wire.

[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
