Description

Technical Field

[0001] This application relates to the field of screw processing equipment technology, and in particular to a wire feeding frame. Background Technology

[0002] In the screw manufacturing and wire processing industries, wire unwinding frames are common auxiliary equipment used to orderly unwind coiled screw-specific wires for subsequent processing.

[0003] In related technologies, the rotating wire feeding frame is commonly used in the market. By pulling one end of the wire that is sleeved on the frame, the wire feeding frame rotates synchronously with the naturally released wire.

[0004] The existing wire feeding frame has the following problems: its pivot is usually set as a fixed rigid rod body and the angle cannot be adjusted, which means that the wire coil needs to be lifted and moved manually when the wire is laid, resulting in low operating efficiency and thus indirectly reducing the efficiency of screw processing. Summary of the Invention

[0005] To improve operational efficiency, this application provides a wire feeding frame.

[0006] The wire feeding frame provided in this application adopts the following technical solution: A cable laying frame includes: a base, a rotating shaft, and a rotating frame. The base is mounted on the ground. The rotating shaft includes an upper rod, a lower rod, and a lowering assembly. The upper rod, the lowering assembly, and the lower rod are coaxially arranged in the vertical direction and connected sequentially. The upper rod is fixedly connected to the rotating frame, and the lower rod is rotatably connected to the base via a bearing.

[0007] By adopting the above solution, the equipment has both wire carrying and multi-angle rotation functions. Workers can operate the tilting component to make the upper rod body drive the rotating frame to bend downwards until it reaches a horizontal position, so as to facilitate reloading or unloading and improve operating efficiency.

[0008] Preferably, the folding assembly includes a universal joint, with its two ends hinged to the upper rod and the lower rod, respectively.

[0009] By adopting the above solution, the universal joint allows the upper rod to tilt at multiple angles relative to the lower rod, and the tilt angle can be fixed by the universal joint self-locking. The hinge structure improves the rigid positioning capability and is suitable for equipment bracket scenarios that require frequent tilting and resetting.

[0010] Preferably, it further includes a metal sleeve, which is slidably fitted onto the outside of the universal joint.

[0011] By adopting the above scheme, the bending degree of freedom of the universal joint can be quickly released and closed.

[0012] Preferably, the rotating frame includes a support frame and a plurality of support columns. The support frame is arranged parallel to the ground to support the screw wires sleeved on the support columns. The plurality of support columns are arranged circumferentially and perpendicular to the support frame.

[0013] By adopting the above solution, the support column and the support frame can simultaneously mount multiple coils of screw wire and maintain the stability of the wire through centrifugal force during rotation, thereby achieving rapid release of materials. Furthermore, the vertical layout of the support column, combined with the weight of the wire itself, forms a symmetrical load distribution, reducing the occurrence of wire shaking and unwinding.

[0014] Preferably, the support frame is composed of two rounded rectangular tubes connected at their geometric centers.

[0015] By adopting the above scheme, two rounded rectangular tubes intersect to form an X-shaped structure. The interlocking of the geometric center enhances the overall torsional stiffness, while the rounded corner design reduces the occurrence of wire scratches.

[0016] Preferably, two supports are provided below the support frame, the two supports are arranged in a horizontal cross shape, and the intersection point is fixedly connected to the top of the upper rod.

[0017] By adopting the above solution, the load-bearing capacity and anti-tipping capacity of the support frame are further improved. After the upper pole is rigidly connected to the intersection of the support, it drives the wire and the rotating frame to rotate under the action of external force.

[0018] Preferably, the support is provided with a plurality of sliding seats, and each of the plurality of sliding seats is vertically provided with a limiting rod, the limiting rod being slidably mounted on the support via the sliding seats.

[0019] By adopting the above scheme, the sliding seat slides along the support track, so that the limiting upright is in close contact with the outer periphery of the stacked screw coil, and the support column applies a certain tension to the wire, thus meeting the rapid positioning requirements of wires of different specifications.

[0020] Preferably, the support column is slidably provided with a pressure rod in the vertical direction, and the pressure rod is horizontally arranged to press down the top of the screw wire sleeved on the support column.

[0021] By adopting the above solution, the starting end of the wire is pressed into the tube before pulling, which reduces the occurrence of wire loosening and also reduces the possibility of accidental wire bouncing and injuring workers during the pulling process.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. Workers can operate the tilting component to cause the upper rod to drive the rotating frame to bend downwards until it reaches a horizontal position, so as to facilitate reloading or unloading and improve operational efficiency; 2. Improved the equipment's load-bearing capacity and anti-tipping ability; 3. It positions and tensions the material, reducing the occurrence of shaking and falling off. Attached Figure Description

[0026] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0027] This application discloses a wire feeding frame. (Refer to...) Figure 1-2 A wire feeding frame includes a base 1, a rotating shaft 2, and a rotating frame 3. The base 1 is erected on the ground. The rotating shaft 2 includes an upper rod 21, a lower rod 22, and a lowering assembly 23. The upper rod 21, the lowering assembly 23, and the lower rod 22 are coaxially arranged in the vertical direction and connected in sequence. The upper rod 21 is fixedly connected to the rotating frame 3, and the lower rod 22 is rotatably connected to the base 1 through a bearing.

[0028] Specifically, the folding assembly 23 includes a universal joint 231 and a metal sleeve 232. The two ends of the universal joint 231 are hinged to the upper rod 21 and the lower rod 22, respectively. Meanwhile, the metal sleeve 232 is slidably sleeved on the outside of the universal joint 231.

[0029] Therefore, the universal joint 231 allows the upper rod 21 to tilt at multiple angles relative to the lower rod 22, realizing spatial bending in a non-single plane. It can also fix the tilt angle by self-locking the universal joint 231. The hinge structure improves the rigid positioning capability and is suitable for equipment brackets 32 that need to be frequently tilted and reset.

[0030] Meanwhile, the metal sleeve 232 completely encloses the universal joint 231, forming a rigid shell to enhance resistance to lateral impacts and effectively reduce sand and dust intrusion or mechanical damage.

[0031] Correspondingly, when the metal sleeve 232 moves down, it releases the bending degree of freedom of the universal joint 231. The universal joint 231 adjusts its angle through the hinge point and drives the upper rod 21 to bend downward, so that the rotating frame 3 is placed horizontally. The upper rod 21 is then guided back to the vertical position to end the folding process, which drives the rotating frame 3 to reset. The metal sleeve 232 then slides upward to cover the universal joint 231 again, thereby constraining and maintaining the axial transmission of the load.

[0032] In summary, this equipment combines wire carrying and multi-angle rotation functions. Workers can operate the tilting component 23 to cause the upper rod 21 to drive the rotating frame 3 to bend downwards until it touches the ground or is in a horizontal position, so as to facilitate reloading or unloading, improve operating efficiency, and thus improve the processing efficiency of screws.

[0033] On the other hand, the rotating frame 3 includes a support frame 31 and several support columns 34. The support frame 31 is arranged parallel to the ground to support the screw wires sleeved on the support columns 34. In this embodiment, a total of four support columns 34 are provided. The four support columns 34 are arranged circumferentially and vertically welded to the surface of the support frame 31.

[0034] Therefore, the support column 34, together with the support bracket 31, can simultaneously accommodate multiple coils of screw wire. When the support bracket 31 rotates in conjunction with the rotating shaft 2, the centrifugal force keeps the coils stable, enabling the rapid loading and unloading of wires of different specifications. The support column 34, through its vertical layout and in conjunction with the weight of the wires, forms a symmetrical load distribution, reducing the occurrence of wire shaking and unwinding.

[0035] Specifically, the support frame 31 is formed by welding two rounded rectangular tubes together with their geometric center as the intersection point, presenting an X-shaped structure. This structure enhances the overall torsional stiffness through geometric center interlocking, evenly distributing the weight of the wire to the four quadrants. Under the action of centrifugal force during rotation, it can still maintain the force balance of each support column 34, reducing unilateral overload.

[0036] Meanwhile, the rounded corner design of the support frame 31 reduces scratches during wire handling and wear from contact with the ground when the wire is laid down.

[0037] On the other hand, two brackets 32 welded in a horizontal cross structure are provided below the support frame 31. Both brackets 32 abut against the lower surface of the support frame 31, and the intersection point is fixedly connected to the top of the upper rod 21.

[0038] Therefore, the bracket 32 ​​further converts the vertical load into a lateral force component, improving the load-bearing capacity and anti-tipping capacity of the support frame 31. It is suitable for dynamic rotational conditions when pulling screw wires. After the upper rod 21 is rigidly connected to the bracket 32 ​​at the intersection point, it can pull the wire under the action of external force, causing the material and the rotating frame 3 to rotate.

[0039] Furthermore, in this embodiment, sliding seats are respectively installed on the four ends of the two supports 32, and the upper surfaces of the four sliding seats are vertically connected and fixed with limit rods 322. The limit rods 322 slide along the length direction of the support 32 through the sliding seats.

[0040] Correspondingly, the sliding seat slides along the track of the bracket 32, so that the limiting upright 322 is in close contact with the outer periphery of the stacked screw coil, and the support column 34 applies a certain tension to the wire, reducing the radial runout generated when the wire rotates, and meeting the rapid positioning requirements of wires of different specifications.

[0041] On the other hand, in this embodiment, a counterweight 35 of appropriate weight can be suspended below the bracket 32 ​​to counteract the eccentric inertial force caused by uneven wire material or uneven winding, reduce the radial runout amplitude when the wire rotates, and effectively reduce the occurrence of wire unwinding or tangling.

[0042] Meanwhile, the appropriately weighted counterweight 35 can balance the overturning moment generated by the support 32 and the material's own weight, improving the equipment's anti-overturning safety during high-speed wire pulling. During the wire pulling pause, the counterweight 35 continuously provides micro-tension, reducing the wire from becoming tangled due to its own weight. When the equipment stops suddenly, the inertial displacement of the counterweight 35 can also absorb the instantaneous impact energy, reducing the risk of wire breakage.

[0043] In addition, a pressure rod 33 is slidably provided on the support column 34 in the vertical direction. The pressure rod 33 is horizontally positioned and is used to press down the top of the screw wire sleeved on the support column 34.

[0044] Correspondingly, before pulling the wire, the operator presses the starting end of the wire under the sliding pressure bar 33 to reduce the occurrence of wire loosening during wire reel handling. When pulling the wire, the pressure bar 33 can apply appropriate pressure to the wire to absorb the tension fluctuations caused by the inertial rotation of the wire reel and maintain the uniform tension of the wire.

[0045] At the same time, it also reduces the occurrence of accidental bouncing of materials that could injure workers when rotating and retrieving screw wires.

[0046] The implementation principle of a wire feeding frame in this application embodiment is as follows: the equipment has both wire carrying and multi-angle rotation functions. The worker can operate the tilting component 23 so that the universal joint 231 and the metal sleeve 232 drive the upper rod 21 to bend downward until the rotating frame 3 touches the ground or is in a horizontal position, so as to facilitate reloading or unloading, effectively improving the operating efficiency and thus improving the screw processing efficiency.

[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
