Description

Technical Field

[0001] This invention relates to the field of metal wire processing equipment technology, and in particular to a wire feeding device for a stranding equipment. Background Technology

[0002] In the twisting production of products such as steel wire ropes, the stability of the center wire's winding is crucial. Currently, horizontal winding frames are widely used due to their simple structure and high load-bearing capacity. However, they face two prominent and interrelated problems: 1. Ineffective handling of poorly laid-out spools: When the wire is not neatly laid out during take-up, the wire on the spools will exhibit unevenness, with some strands coming out the inside and others coming in the outside. Traditional horizontal pay-off frames subject the wire to severe lateral compression and axial friction when releasing such poorly laid-out spools, causing the pay-off tension to fluctuate wildly. This unstable tension is directly transmitted to the stranding machine, causing the center wire to "arch" or "shrink" within the strands, severely impacting product quality and even leading to frequent wire breakage and disrupting normal production.

[0003] 2. The shaft replacement operation is laborious and inefficient: The I-beams of the horizontal wire feeding frame are usually very heavy. When replacing them, it is necessary to manually or with the help of a crane to remove and install them from the main shaft. The centering and adjustment are cumbersome. The whole process is time-consuming and labor-intensive, resulting in long equipment downtime.

[0004] Therefore, a wire feeding device for a twisting equipment is provided. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a wire feeding device for a twisting equipment, which improves wire feeding stability. By using an adjustable rotary damper in conjunction with the swing arm and crank connecting rod to form a tension buffer pool, it absorbs tension spikes caused by poor wire feeding, avoids drastic tension fluctuations, prevents the center wire from arching, shrinking, or breaking, and ensures the quality of twisted products, thus overcoming the shortcomings of existing technologies.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A stranding equipment wire feeding device includes a base, with connecting sleeves fixed on both sides of one end of the base. Two connecting sleeves are rotatably connected to swing arms via a rotating shaft. A crank connecting rod is connected to one side of each swing arm. A wire feeding reel is installed between the two swing arms via a fixed main shaft. A damper is installed on one side of one of the swing arms. One end of the fixed main shaft is rotatably connected to the middle of the damper.

[0007] As a further embodiment of the present invention: a U-shaped rod is welded to the top of the base, and a guide wheel is installed on one side of the top of the U-shaped rod and above the wire feeding reel.

[0008] As a further embodiment of the present invention: a clamping handle is installed on the top of the end of the crank connecting rod away from the wire feeding reel.

[0009] As a further embodiment of the present invention: connecting blocks are welded to the top of the base and one side of the inner wall, and a locking rope is bolted between the two connecting blocks, with the locking rope wrapped in the groove outside the damper.

[0010] As a further embodiment of the present invention: each of the two swing arms is provided with a mounting slot, and the two ends of the fixed spindle are respectively engaged in the two mounting slots.

[0011] As a further embodiment of the present invention, the damper is an adjustable rotary damper.

[0012] As a further embodiment of the present invention: the base is U-shaped, and the wire feeding reel is located at the top of the opening of the base.

[0013] The beneficial effects of this invention are as follows: 1. Improve the stability of wire feeding. The adjustable rotary damper, together with the swing arm and crank connecting rod, forms a tension buffer pool to absorb tension spikes caused by poor wire feeding, avoid drastic tension fluctuations, prevent the center wire from arching, shrinking or breaking, and ensure the quality of twisted products.

[0014] 2. Simplify shaft changing operation: simply loosen the locking rope and pull the clamping handle to open the installation bay, easily disassemble and install the wire feeding I-beam reel, eliminating the need for tedious centering adjustments, reducing manpower and equipment downtime, and significantly improving shaft changing efficiency.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0020] Example 1, referring to Figure 1-3 A stranding equipment wire feeding device includes a base 1. Connecting sleeves 13 are fixed on both sides of one end of the base 1. The two connecting sleeves 13 are rotatably connected to swing arms 10 through a rotating shaft 11. A crank connecting rod 9 is connected to one side of the swing arm 10. A wire feeding reel 5 is installed between the two swing arms 10 through a fixed main shaft 14. A damper 6 is installed on one side of one of the swing arms 10. The damper 6 is an adjustable rotary damper. One end of the fixed main shaft 14 is rotatably connected to the middle of the damper 6.

[0021] A U-shaped rod 2 is welded to the top of the base 1, and a guide wheel 3 is installed on one side of the top of the U-shaped rod 2 and above the wire feeding reel 5.

[0022] A clamping handle 8 is installed on the top of the end of the crank connecting rod 9 away from the wire feeding reel 5.

[0023] Connecting blocks 7 are welded to the top of the base 1 and one side of the inner wall. A locking rope 4 is bolted between the two connecting blocks 7. The locking rope 4 is wrapped in the groove outside the damper 6.

[0024] Both swing arms 10 are provided with mounting slots 12, and the two ends of the fixed spindle 14 are respectively inserted into the two mounting slots 12.

[0025] The base 1 is U-shaped, and the wire feeding reel 5 is located at the top of the opening of the base 1.

[0026] After the center wire is drawn out from the horizontal feed reel 5, it passes around the guide wheel 3. When the feed reel is obstructed due to poor wire feeding and the tension increases, the increased tension overcomes the resistance of the damper 6, pulling the swing arm 10 to rotate and the crank connecting rod 9 to lift. When the tension decreases, the swing arm 10 and the crank connecting rod 9 fall back. This up-and-down swinging process automatically feeds in and out a pre-set section of wire, acting like a "tension buffer pool" to effectively absorb tension spikes caused by wire tangling and jamming, ensuring a basically constant output tension.

[0027] When it is necessary to stop the wire feeding, the crank connecting rod 9 is raised by clamping handle 8. The raised crank connecting rod 9 presses against the locking rope 4, and the rotation of the damper 6 is locked by the locking rope 4, which can stop the wire feeding reel 5.

[0028] Example 2 is an optimization based on Example 1, specifically: When replacing the pay-off I-beam 5, simply loosen the locking rope 4, use the clamping handle 8 to pull the crank connecting rod 9 upwards so that the mounting slot 12 faces the outside of the base 1, and the pay-off I-beam 5 can be removed from the mounting slot 12 for easy replacement with a new pay-off I-beam 5.

[0029] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
