Description

Technical Field

[0001] The present invention belongs to the technical field of wire winding and unwinding equipment, and specifically relates to a flexible wire rotating winding and unwinding device. Background Art

[0002] The reinforced spring steel wire is composed of a main shaft steel wire and spring wires wound around the outside of the main shaft steel wire. Compared with ordinary spring steel wires, it has better performance and is widely used in fields such as pipeline dredging and shock absorption. During the production process of the reinforced spring steel wire, the main shaft steel wire not only moves forward but also rotates around its axis, enabling the spring wires conveyed by the spring machine to be orderly wound around the outside of the main shaft steel wire.

[0003] In the traditional production process of the reinforced spring steel wire, the spool rotates around its own axis and also rotates around the end as the center, causing the main shaft steel wire to rotate while being wound and unwound, resulting in an excessive moment of inertia of the bearing driving the spool movement. This not only consumes a large amount of energy but also increases the danger of the equipment. Therefore, the present invention designs a flexible wire rotating winding and unwinding device to reduce the moment of inertia of the spool and increase the operating stability. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the technical problem to be solved by the present invention is to provide a flexible wire rotating winding and unwinding device.

[0005] The present invention adopts the following technical solutions to solve the above-mentioned technical problems:

[0006] A flexible wire rotating winding and unwinding device includes symmetrically arranged wire winding modules and wire unwinding modules; both the wire winding module and the wire unwinding module include a spool fixing component, a spool, an unwinding fork, and a fork mounting bracket. The spool fixing component includes a spool fastener, a fixed slide rail, a sliding module, and a spool bracket.

[0007] The sliding module is slidably connected to the fixed slide rail. The spool bracket is rotatably installed on the upper part of the sliding module. The spool is inserted on a support rod at the center of the spool bracket and is tightly connected through a spool fastener; the fork mounting bracket is located inside the fixed slide rail. A rotating motor is provided on the upper part of the fork mounting bracket, and the unwinding fork is connected to the rotating motor.

[0008] The wire is led out from the spool of the wire unwinding module, passes through the unwinding forks of the wire unwinding module and the wire winding module in sequence, and then is connected to the spool of the wire winding module; when the spools of the wire winding module and the wire unwinding module rotate while the unwinding forks do not rotate, the wire is wound and unwound in a translational but non-rotational manner; when the spools of the wire winding module and the wire unwinding module and the unwinding forks rotate synchronously in the same direction and at the same speed, the wire rotates but does not translate; when the spools and the unwinding forks of the wire winding module and the wire unwinding module rotate in the same direction at different speeds, the wire is wound and unwound in a synchronous manner of translation and rotation.

[0009] Furthermore, the wire-opening fork includes a disc, on one side of which there are symmetrically arranged long rods. The inside of the long rods is hollow to serve as a wire groove, and the wire passes through the central hole of the disc and then through the wire groove of the long rods.

[0010] Furthermore, the spool fastener includes a fixing cone, a reinforcing ring and a reinforcing bolt; the fixing cone is tightly connected to the support rod at the center of the spool holder, the reinforcing bolt is simultaneously tightly connected to the inner side of the tail of the fixing cone and the support rod at the center of the spool holder, and the reinforcing ring is sleeved on the outer side of the tail of the fixing cone.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0012] The present invention separates the two movements of wire winding and unwinding and wire self-rotation. The spool holder drives the spool to rotate around its own axis to realize wire winding and unwinding, and the wire-opening fork drives the wire to rotate. It solves the problem that the wire cannot rotate by itself during the conventional spool wire winding and unwinding, and also solves the problem of large moment of inertia caused by the fact that in the existing production, the spool not only has to rotate by itself but also has to rotate in space with the end as the center. The sliding module can slide on the fixed slide rail, which is convenient for adjusting the position of the spool in the horizontal direction. The spool fastener is easy to disassemble and replace, which is beneficial to the installation and replacement of the spool. The rotation speeds of the wire-opening fork and the spool are easy to control. By controlling the rotation speeds of the wire-opening fork and the spool and their cooperation, the self-rotation speed and the wire winding and unwinding speed of the wire under different working conditions can be fitted, so as to achieve the purpose of controlling the winding density of the wire. This device effectively solves the defects existing in the wire rotation during the current spring steel wire production, and has a higher degree of automation, a simpler structure, is convenient for maintenance, and improves production efficiency.

[0021] Refer to Figures 1 to 6 , the present invention provides a flexible wire rotating winding and unwinding device, which includes a symmetrically arranged wire winding module and a wire unwinding module; the wire winding module and the wire unwinding module have the same structure, and both include a spool fixing component 1, a spool 3, an unwinding fork 4 and a fork mounting bracket 5. The spool fixing component 1 includes a spool fastener 2, a fixed slide rail 6, a sliding module 7 and a spool holder 8;

[0022] The fixed slide rail 6 is a bracket with guide rails on both sides and is fixed to the ground; the sliding module 7 is installed on the fixed slide rail 6, and the position of the sliding module 7 on the fixed slide rail 6 is adjustable; a triangular bracket is provided on the upper part of the sliding module 7, and a driving motor is provided on the triangular bracket. The spool holder 8 is rotatably installed on the triangular bracket and is connected to the driving motor; a support rod is provided at the center of the spool holder 8, and the spool 3 is sleeved on the support rod of the spool holder 8. The spool fastener 2 is fixed at the end of the support rod to realize the fastening connection between the spool 3 and the spool holder 8; the horizontal movement of the spool 3 is realized through the sliding module 7, which is not only convenient for disassembling and replacing the spool 3, but also adjusts the position of the spool 3 during the winding and unwinding process; the spool holder 8 is rotated by the driving motor, and the spool 3 rotates together with the spool holder 8. The horizontal movement of the wire is achieved through two spools 3 to achieve the purpose of winding and unwinding;

[0023] The fork mounting bracket 5 is located inside the fixed slide rail 6 and is spaced from the fixed slide rail 6 by a certain distance; a rotating motor 12 is provided on the fork mounting bracket 5, the unwinding fork 4 is connected to the rotating motor 12, and the wire passes through the unwinding fork 4 and is connected to the spool 3; the unwinding fork 4 is rotated by the rotating motor 12 to realize the rotation of the wire.

[0024] As Figure 4 shown, the unwinding fork 4 includes a disc 401, two long rods 402 are symmetrically provided on one side of the disc 401, and a reinforcing rib 403 connected to the disc 401 is provided in the middle of the long rod 402 to increase the stability of the long rod 402; one of the long rods 402 is used to balance the moment of inertia during the rotation process, and the other long rod 402 is hollow inside and used as a wire guide groove. The wire passes through the central hole of the disc 401 and passes through the wire guide groove of the long rod 402, and finally winds around the spool 3. The schematic diagram of the wire winding is asFigure 5 as shown

[0025] As Figure 6 shown, the spool fastener 2 includes a fixing cone 9, a reinforcing ring 10 and a reinforcing bolt 11; the fixing cone 9 is conical, and has a through hole along the axis with a diameter slightly larger than the rod of the spool holder 8, so that the fixing cone 9 is tightly connected to the rod of the spool holder 8. Threads are provided on both the inner and outer sides of the tail of the fixing cone 9; the reinforcing bolt 11 is a perforated frustum, the outer diameter of which is slightly smaller than the inner diameter of the fixing cone 9, and the inner diameter of which is the same as the diameter of the rod of the spool holder 8. The reinforcing bolt 11 is inserted into the tail of the fixing cone 9 and is threadedly connected thereto, and the reinforcing bolt 11 is also tightly connected to the rod of the spool holder 8; the reinforcing ring 10 is provided with internal threads, and the reinforcing ring 10 is sleeved on the outer side of the tail of the fixing cone 9 and is threadedly connected thereto. The spool fastener 2 is connected to the rod of the spool holder 8 by a locking and tightening method to axially limit the spool 3 and prevent the spool 3 from sliding horizontally on the rod of the spool holder 8.

[0026] The spool 3 is a conventional winding spool with positioning holes, which can be horizontally inserted into the rods of the spool holder 8 and rotate together with the spool holder 8 to realize the winding and unwinding of the wire by rotating the spool 3.

[0027] The working principle and working process of the present invention are as follows:

[0028] The wire is arranged on the spool 3 of the unwinding module, and the spool 3 of the winding module is an empty spool for storing the finished wire. The spool 3 is inserted into the rod of the spool holder 8 and fixed by the spool fastener 2; the position of the sliding module 7 on the fixed slide rail 6 is adjusted, and then the position of the spool 3 is adjusted; the wire is led out from the spool 3 of the unwinding module, passes through the wire-opening fork 4 of the unwinding module and the wire-opening fork 4 of the winding module in sequence, and finally winds around the spool 3 of the winding module.

[0029] When the spools 3 of the winding module and the unwinding module rotate while the two wire-opening forks 4 do not rotate, the wire moves linearly without rotating and is conveyed in a non-rotating manner to realize the winding and unwinding in the traditional mode. When the spools 3 of the winding module and the unwinding module and the wire-opening forks 4 rotate synchronously in the same direction and at the same speed, the wire rotates without moving linearly; further, when the spools 3 of the winding module and the unwinding module and the wire-opening forks 4 rotate in the same direction at different speeds, the wire rotates and moves linearly at the same time, achieving the purpose of rotary winding and unwinding. By controlling the rotation speed of the wire-opening fork 4, the rotation speed of the wire can be controlled. Taking the production of reinforced spring steel wire as an example, the density of the outer layer of spring wire winding can be controlled.

[0030] Those not described in the present invention are applicable to the prior art.
