Description

Technical Field

[0001] The utility model relates to the technical field of wire-reeling and wire-paying equipment, in particular to an automatic wire-paying and shaft-beating machine. Background Art

[0002] The production process of steel wire includes raw material selection, iron oxide removal, drying, coating, heat treatment, wire drawing, plating, wire winding and packaging, and finished product inspection and warehousing. In the wire winding and packaging process, the coated steel wire is wound on the wire drum by the wire winding machine for export. However, the steel wire purchased by consumers is usually a wire coil wound on an I-shaped wheel. The amount of steel wire on the wire coil is large, which is not conducive to the use of the production process. For this reason, the incoming wire coil will be wired and divided, and the incoming large wire coil will be wound on multiple small I-shaped wheels (wire drums) for division.

[0003] In the prior art, when paying out the incoming wire coil, the workers lay the wire on the pay-off rack. During the wiring process, the workers need to tidy up the wire to prevent the wire from being disturbed. However, during the operation, the manual wiring of the workers is prone to produce back-wires. For example, uneven wiring can cause the wire to be disturbed. For this reason, a corresponding pay-off device is provided in the prior art, such as a patent application number CN202222587869.3, entitled A Simple Pay-off Device for I-shaped Wheels. In the patent, the I-shaped wheel used for winding the wire is mounted on a bottom plate, and is coaxially arranged with a transmission shaft rotatably connected to the bottom plate. Pulling the wire can drive the I-shaped wheel to rotate on the bottom plate for pay-off. The brake disc coaxially arranged with the I-shaped wheel can also have friction with the matching friction plate to prevent the reduction of the tension at the pay-off end of the wire. The I-shaped wheel continues to rotate under the action of inertia, causing the wire on the I-shaped wheel to become knotted.

[0004] Although the above-mentioned wire-paying device can stop the I-spool during wire-paying to avoid disturbing the wire, the disassembly and assembly of the entire I-spool is extremely inconvenient, because there are multiple incoming I-spools, and each I-spool needs to be reeled. The above-mentioned structure is inconvenient for disassembly of the I-spool, affecting the efficiency of the entire reeling work. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides an automatic wire-laying and shaft-tying machine, which solves the problem of inconvenient assembly and disassembly of the spool on the bottom plate in the prior art.

[0006] To achieve the above-mentioned purpose, the utility model adopts the following technical solution: an automatic wire-laying and shaft-beating machine, including a base plate and two coaxially arranged ejector shafts on the base plate that can move relative to or away from each other, each ejector is rotatably arranged on the base plate, and any ejector is also provided with a brake buffer mechanism for use in conjunction with it.

[0007] The principle of the utility model is as follows: the hollow setting of the I-shaped wheel is used. When installing, the I-shaped wheel provided with the steel wire is placed on the bottom plate, and the movement of the two ejector shafts is controlled to fix the I-shaped wheel and make the I-shaped wheel slightly suspended on the bottom plate. At this time, the steel wire on the I-shaped wheel is placed on the small roller, and the small roller can be driven to rotate by a servo motor. The start and stop of the servo motor can control the shutdown by the wire-reeling time, and the deceleration shutdown is controlled by the inverter parameters during the shutdown process; since the I-shaped wheel is fixed with the two ejector shafts, and the two ejector shafts can rotate on the bottom plate, the steel wire can be pulled when the small roller rotates to ensure that the I-shaped wheel rotates and releases the wire; when the small roller slows down and stops, the existence of the brake buffer mechanism can prevent the I-shaped wheel from continuously rotating under the action of inertia to cause the steel wire to be disturbed, thereby ensuring stability during the wiring process.

[0008] Compared with the prior art, the utility model has the following beneficial effects:

[0009] The utility model provides an automatic wire-laying and shaft-beating machine which cooperates with a small roller to ensure that the steel wire on the incoming material spool can be rolled up, and the two ejector shafts moving on the bottom plate can facilitate the loading and unloading of different incoming material spools, which is more convenient than the prior art and can improve the rolling efficiency.

[0010] Furthermore, the ejector shaft is horizontally arranged on the bottom plate, and a rotatably connected moving cylinder is disposed outside the ejector shaft, and the moving cylinder reciprocates horizontally on the bottom plate under the action of the driving assembly.

[0011] Furthermore, the driving assembly includes a fixed cylinder fixed to the base, an arc-shaped limiting groove wound around the periphery of the fixed cylinder, and a push rod moving in the limiting groove. The moving cylinder is sleeved in the fixed cylinder, the push rod passes through the limiting groove and is fixed to the moving cylinder, and the push rod slides along the limiting groove to drive the moving cylinder to move in the horizontal direction.

[0012] Furthermore, the fixing tube is horizontally arranged on the bottom plate and is mounted on the bottom plate through two fixing brackets arranged side by side.

[0013] Furthermore, the brake buffer mechanism includes a brake disc coaxially arranged with the ejector shaft, a brake belt wrapped around the periphery of the brake disc and a fixing assembly for tightening the brake belt. The brake disc is fixed to one end of the ejector shaft away from the other ejector shaft, and the fixing assembly is fixed to the moving cylinder.

[0014] Furthermore, the fixing assembly includes a fixing seat fixed to the moving cylinder, a screw rod passing through the fixing seat, a tension spring sleeved on the screw rod, and a force adjustment nut movably arranged along the screw rod, one end of the screw rod is fixed to one end of the brake belt, the other end of the brake belt is fixed to the fixing seat, the tension spring and the force adjustment nut are both arranged near the other end of the screw rod, and the tension spring is located between the force adjustment nut and the fixing seat.

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0026] like Figure 1 , 2As shown in Figure 3, an automatic wire laying and shafting machine comprises a horizontally arranged bottom plate 1, on which two ejector shafts 3 for fixing the incoming material spool 2 are arranged. Since the incoming material spool 2 is hollow, the two ejector shafts 3 face the two hollow ends of the incoming material spool 2 and move toward the incoming material spool 2 to fix the incoming material spool 2, and the two ejector shafts 3 move backwards and separate from the incoming material spool 2 to realize the disassembly of the incoming material spool 2, which is convenient for the disassembly and assembly of the incoming material spool 2.

[0027] Since the incoming material spool 2 needs to rotate during the wire release process, in order to achieve the purpose that the two thimble shafts 3 can move relative to or away from each other and enable the incoming material spool 2 to rotate, as shown in FIG. Figure 1 , 2 As shown in Figures 3 and 4, in this embodiment, a rotating and connected moving cylinder 5 is sleeved outside each ejector shaft 3, and the moving cylinder 5 is coaxially arranged with the ejector shaft 3. A plurality of bearings 31 are arranged between the ejector shaft 3 and the moving cylinder 5 to realize the rotating connection between the ejector shaft 3 and the moving cylinder 5, and at least one end of the ejector shaft 3 passes through the moving cylinder 5 and is located outside the moving cylinder 5, and one end of the ejector shaft 3 located outside the moving cylinder 5 is arranged opposite to another ejector shaft 3. In order to enable the ejector shaft 3 to move horizontally on the bottom plate 1, the movement of the moving cylinder 5 can also achieve the purpose of moving the ejector shaft 3. For this reason, in this embodiment, the moving cylinder 5 reciprocates in the horizontal direction on the bottom plate 1 under the action of the driving assembly. Specifically, the driving assembly includes a fixed cylinder 4 fixed to the base, a limiting groove 41 of an arc-shaped structure wound around the outer periphery of the fixed cylinder 4, and a push rod 51 moving in the limiting groove 41. The moving cylinder 5 is sleeved in the fixed cylinder 4, and the push rod 51 passes through the limiting groove 41 and is fixed to the moving cylinder 5. The push rod 51 slides along the limiting groove 41 to drive the moving cylinder 5 to move in the horizontal direction. Among them, the fixed cylinder 4 is horizontally arranged on the bottom plate 1 and is mounted on the bottom plate 1 through two fixed brackets 11 arranged side by side. When in use, since the limiting groove 41 is an arc-shaped groove and has a certain slope, when an external force is applied to the push rod 51 to force the push rod 51 to move along the limiting groove 41, it drives the moving seat to rotate and displaces in the horizontal direction until it contacts the other end of the limiting groove 41 to achieve the limit. Due to the structure of the limiting groove 41, when the movable cylinder 5 is subjected to a reaction force in the horizontal direction (the reaction force generated when clamping the incoming material spool 2), the limiting groove 41 can offset the horizontal force, limit the movable cylinder 5 and the fixed cylinder 4, and prevent the push rod 51 from moving in the opposite direction, thereby enabling the driving assembly in this embodiment to push the movable seat and the ejector shaft 3 to move and position them, ensuring that the cooperation of the two ejector shafts 3 can achieve the purpose of clamping and fixing the incoming material spool 2.

[0028] like Figure 1 , 2As shown in Figure 3, in order to allow the ejector shaft 3 to smoothly enter the hollow structure of the incoming I-shaped wheel 2, a truncated cone structure 34 is provided at one end of any ejector shaft 3 facing the other ejector shaft 3, which is contracted toward the other ejector shaft 3; in order to facilitate the fixation of the incoming I-shaped wheel 2 and the two ejector shafts 3, a positioning block 33 for use is fixed on any ejector shaft 3, and the positioning block 33 is a horizontally arranged pin structure, and one end of the pin structure is fixed to the connecting piece 32 fixed on the ejector shaft 3, and the vertical projection of the other end of the pin is located on the ejector shaft 3 and close to the truncated cone structure 34. When installing, when the incoming I-shaped wheel 2 cooperates with the truncated cone structure 34, the truncated cone structure 34 can slightly raise the incoming I-shaped wheel 2 and set a gap with the bottom plate 1, and the ejector shaft 3 continues to move toward the incoming I-shaped wheel 2, which can make the positioning block 33 enter the groove on the incoming I-shaped wheel 2 for limiting, ensuring that the ejector shaft 3 can rotate when the incoming I-shaped wheel 2 rotates, reducing friction resistance.

[0029] like Figure 1 , 2 As shown in Figures 3 and 4, in order to facilitate loading and unloading of the incoming I-shaped wheel 2 at a fixed position on the bottom plate 1, a guide groove 8 for positioning is further provided in the space between the two ejector shafts 3 in this embodiment. There are two symmetrical guide grooves 8, each of which includes a horizontal section 82 and an inclined section 81 arranged in a symmetrical manner. The horizontal section 82 is fixed on the bottom plate 1 and is perpendicular to the axis of the ejector shaft 3. The upper end of the inclined section 81 is connected to the horizontal section 82, and the lower end of the inclined section 81 extends to the outside of the bottom plate 1. The distance between the two guide grooves 8 is just adapted to the axial length of the incoming I-shaped wheel 2 to be laid out. It is more labor-saving to move the incoming I-shaped wheel 2 along the two inclined sections to the bottom plate 1, and then enter between the two levels for limiting. At the same time, a concave positioning groove 83 can be provided on the horizontal section 82, so that the incoming I-shaped wheel 2 can be braked when it rolls to the position, which is convenient for the two ejector shafts 3 to fix the incoming I-shaped wheel 2.

[0030] The principle of the utility model is as follows: the incoming I-shaped wheel 2 to be rolled is brought into a suitable position on the bottom plate 1 along the two inclined sections 81, and the two operators cooperate with each other by the left and right hands or the left and right hands of the same operator, and the push rod 51 is pushed at the same time to move the moving cylinder 5, and the two ejector shafts 3 are driven to move relatively into the hollow position of the incoming I-shaped wheel 2. Due to the truncated cone structure 34, the incoming I-shaped wheel 2 can be slightly lifted off the bottom plate 1, and the two ejector shafts 3 continue to move to drive the two positioning blocks 33 into the matching grooves, so that the I-shaped wheel 2 is fixed between the two ejectors. At this time, pulling the steel wire on the I-shaped wheel 2 can drive the I-shaped wheel 2 and the two ejectors to rotate; when the steel wire on the I-shaped wheel 2 is released, the two push rods 51 are pushed in the opposite direction to drive the two ejector shafts 3 to move in the opposite direction, so that the I-shaped wheel 2 is separated from the two ejector shafts 3, and the unloading of the I-shaped wheel 2 is completed; the loading of the new I-shaped wheel 2 can be operated according to the above steps.

[0031] The utility model is provided with an automatic wire-laying and shaft-beating machine which cooperates with the use of a small roller to ensure that the steel wire on the incoming material spool 2 can be rolled up, and the two ejector shafts 3 moving on the bottom plate 1 can facilitate the loading and unloading of different incoming material spools 2, which is more convenient than the prior art and can improve the rolling efficiency.

[0032] In order to prevent the incoming material spool 2 from continuing to rotate under the action of inertia when the small roller slows down and stops, causing the steel wire on the incoming material spool 2 to be disturbed, this embodiment also provides a brake buffer mechanism, which can be installed in conjunction with any ejector shaft 3. Figure 1 , 2 As shown in Figures 3 and 5, in this embodiment, the brake buffer mechanism includes a brake disc 7 coaxially arranged with the ejector shaft 3, a brake belt 71 wound around the outer periphery of the brake disc 7, and a fixing assembly for tightening the brake belt 71. The brake disc 7 is fixed to one end of the ejector shaft 3 away from the other ejector shaft 3; the fixing assembly includes a fixing plate 6 fixed to the moving cylinder 5, a fixing block 61 fixed on the fixing plate 6, a screw rod 9 penetrating the fixing block 61, a tension spring 91 sleeved on the screw rod 9, and a force adjustment nut 92 movably arranged along the screw rod 9, one end of the screw rod 9 is fixed to one end of the brake belt 71, the other end of the brake belt 71 is fixed to the fixing block 61, the tension spring 91 and the force adjustment nut 92 are both arranged near the other end of the screw rod 9, and the tension spring 91 is located between the force adjustment nut and the fixing block 61. There is a large friction between the brake disc 7 and the brake belt 71. When in use, the friction between the brake belt 71 and the brake disc 7 is increased by tightening the nut to compress the tension spring 91, thereby achieving the effect of stopping without disturbing the machine.

Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
