Description

[0001] This utility model belongs to the technical field of wrapping machine units, and in particular relates to a wrapping machine unit for the production of fire-resistant cables. Background Technology

[0002] The manufacturing process of wires and cables involves wrapping steel tape around the wire core. During production, multiple sets of processing equipment are required to wrap the steel tape around the wire core. These multiple sets of processing equipment generally include a wire feeding machine, a double-layer wrapping machine, a double-layer concentric steel tape armor wrapping machine, a synchronous frequency conversion speed control electrical cabinet, a double-wheel traction machine, and a wire take-up machine, which together form a wrapping unit to complete the wire feeding, processing, and take-up of the wire.

[0003] However, existing technologies have some problems: current wrapping machines are composed of multiple sets of different equipment. In order for the tracks of multiple sets of equipment to be on the same level when conveying cables, multiple sets of equipment need to be installed accordingly. However, existing wrapping machines cannot determine the cable conveying track during installation, so the installation accuracy is not achieved, which may lead to misalignment between the equipment, reduce processing accuracy, increase the risk of equipment damage, and have certain limitations. Therefore, we propose a wrapping machine for fire-resistant cable production. Summary of the Invention

[0004] To address the problems existing in the prior art, the purpose of this utility model is to provide a wrapping machine unit for the production of fire-resistant cables. By using limiting components, limiting components can be set on both the pay-off machine and the take-up machine. By using limiting components, the cable conveying position is determined first and then positioned, thereby improving the accuracy of equipment installation. At the same time, the limiting components can prevent the cable from moving during conveying, thereby improving the straightness of the cable.

[0028] To further understand the utility model content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0029] like Figures 1 to 6As shown in the figure, the present invention provides a wrapping machine unit for producing fire-resistant cables, comprising: a wire feeding machine 1, a double-layer wrapping machine 2, a double-layer concentric steel strip armored wrapping machine 3, a synchronous frequency conversion speed control electrical cabinet 4, a double-wheel traction machine 5, and a wire take-up machine 6. The wire feeding machine 1, the double-layer wrapping machine 2, the double-layer concentric steel strip armored wrapping machine 3, the synchronous frequency conversion speed control electrical cabinet 4, the double-wheel traction machine 5, and the wire take-up machine 6 are arranged in sequence for processing fire-resistant cables 11; a limiting component 7 and an adjusting component 8 are provided, the limiting component 7 and the adjusting component 8 are movably connected, the adjusting component 8 is disposed on the bracket of the wire take-up machine 6, and the limiting component 7 is located on the auxiliary roller 9 of the wire take-up machine 6 for limiting the fire-resistant cable 11.

[0030] Specifically, according to the appendix Figure 1 As shown, the positions of the cable feeding machine 1, double-layer wrapping machine 2, double-layer concentric steel strip armored wrapping machine 3, synchronous frequency conversion speed control electrical cabinet 4, double-wheel traction machine 5, and take-up machine 6 are displayed. In use, the cable is first fed out by the cable feeding machine 1, and then the double-layer wrapping machine 2, double-layer concentric steel strip armored wrapping machine 3, synchronous frequency conversion speed control electrical cabinet 4, and double-wheel traction machine 5 armor the cable with fire-resistant material. Then the take-up machine 6 collects the cable, and the wrapping of the fire-resistant cable 11 is completed in sequence. The above-mentioned equipment is all existing technology, and the operation process is familiar to those in this field. Therefore, it will not be described in detail.

[0031] It should be noted that before use, the position of the limiting component 7 is adjusted by rotating the adjusting component 8. Then, based on the position of the limiting component 7, the installation position of each device can be determined by a level. This ensures that the cable movement trajectories of the double-layer wrapping machine 2, the double-layer concentric steel belt armor wrapping machine 3, the synchronous frequency conversion speed control electrical cabinet 4, and the double-wheel traction machine 5 are on the same horizontal level. This prevents uneven cable tension caused by misalignment between devices during production, which could lead to cable deviation during transport. Subsequently, the limiting component 7 limits and fixes the cable end to prevent the cable from moving on the auxiliary roller 9. This improves the straightness of the cable, solves the problem of cable deviation during transport, improves processing accuracy, reduces the risk of equipment damage, and improves the stability and service life of the equipment.

[0032] It is worth noting that limit components 7 can also be set on the wire feeding machine 1, so that the two sets of limit components 7 of the wire feeding machine 1 and the wire taking machine 6 correspond to each other, which can improve the accuracy and speed of installation.

[0033] Furthermore, the limiting component 7 includes two sets of collars 701. A bearing 704 is provided inside the collar 701. The bearing 704 is sleeved on the outer surface of the auxiliary roller 9. A connecting rod 703 is provided at the lower end of the collar 701. One end of the connecting rod 703 is provided on the adjusting component 8.

[0034] Specifically, such as Figures 1 to 3 As shown, by designing the bearing 704 to be sleeved on the outer surface of the auxiliary roller 9, the auxiliary roller 9 will not drive the collar 701 to rotate when it rotates, thereby achieving the effect of avoiding affecting the normal use of other structures of the limit assembly 7.

[0035] Furthermore, the adjustment component 8 includes a turntable 801 and a lead screw 802. The take-up machine 6 bracket has a slot 10, the lead screw 802 is set in the slot 10, and one end of the connecting rod 703 is sleeved on the outer surface of the lead screw 802.

[0036] Specifically, such as Figure 2 and Figure 3 As shown, rotating the turntable 801 causes the lead screw 802 to rotate, thereby causing the connecting rod 703 to slide on the outer surface of the lead screw 802 for position adjustment, thus achieving the effect of conveniently adjusting the limiting component 7 according to the usage.

[0037] Furthermore, a clamping mechanism 702 is provided between the two sets of collars 701, with one end of the clamping mechanism 702 being positioned vertically opposite to the surface of the auxiliary roller 9.

[0038] Specifically, such as Figure 2 and Figure 3 As shown, when the cable passes through the auxiliary roller 9, it is pressed down by the pressing mechanism 702, which is positioned above the cable and in contact with it, thereby limiting the position of the cable. This ensures that the cable can only move within the space formed by the auxiliary roller 9, the two sets of collars 701, and the pressing mechanism 702, thus achieving the effect of limiting the position of the cable and preventing it from lifting and falling off at the end of the cable winding.

[0039] Furthermore, the clamping mechanism 702 includes a mounting plate 7021, a protrusion is provided at the upper end of the collar 701, a groove is provided on the upper surface of the protrusion, and one end of the mounting plate 7021 is engaged in the groove.

[0040] Specifically, such as Figure 3 As shown, the mounting plate 7021 and the protrusion cooperate with each other, so that the mounting plate 7021 can be installed by bolts, which facilitates the disassembly and maintenance of the entire clamping mechanism 702. The distance between the two sets of collars 701 can be adjusted. Therefore, the length of the mounting plate 7021 can be adjusted according to the distance between the two sets of collars 701 to avoid the failure of the clamping mechanism 702.

[0041] It should be noted that the spacing between the two sets of collars 701 is mainly adjusted according to the size of the cable in order to better contact the cable and limit its movement.

[0042] Furthermore, a movable plate 7022 is provided on the upper end of the mounting plate 7021, a handle is provided on the upper end of the movable plate 7022, a screw 7025 is provided on the lower end of the movable plate 7022, a pressure plate 7023 is rotatably installed on the lower end of the screw 7025, and the screw 7025 is threadedly connected to the mounting plate 7021.

[0043] Specifically, such as Figure 3 and Figure 4 As shown, rotating the movable plate 7022 drives the screw 7025 to rotate on the mounting plate 7021. The screw 7025 moves downward, thereby pressing down the pressure plate 7023, thus achieving the effect of convenient use.

[0044] Furthermore, a rotating sleeve 7026 is provided at the upper end of the pressure plate 7023, and one end of the screw 7025 is rotatably installed inside the rotating sleeve 7026;

[0045] Specifically, Figure 4 and Figure 5 As shown, when the screw 7025 rotates, one end of the screw 7025 will rotate inside the rotating sleeve 7026 at the upper end of the pressure plate 7023. In this way, the pressure plate 7023 will not rotate with the screw 7025, thereby avoiding affecting the pressing effect of the pressure plate 7023.

[0046] Furthermore, telescopic guide rods 7024 are provided on both sides of the pressure plate 7023, with the upper end of the telescopic guide rods 7024 located on the lower surface of the mounting plate 7021;

[0047] Specifically, such as Figure 4 As shown, two sets of telescopic guide rods 7024 limit the two ends of the pressure plate 7023, and in conjunction with the rotating sleeve 7026, the pressure plate 7023 is kept in a neutral position. Then, when the pressure plate 7023 is pressed down, the telescopic guide rods 7024 will extend, thereby achieving the effect of guiding and positioning the pressure plate 7023.

[0048] Furthermore, the inner wall surface of the pressure plate 7023 has multiple sets of installation grooves, which are equidistantly arranged, and the installation grooves are equipped with anti-fastening mechanisms 705, which are attached to the fire-resistant cable 11.

[0049] Specifically, such as Figures 4 to 6 As shown, the anti-fastening mechanism 705 is designed inside the mounting slot so that when the pressure plate 7023 is pressed down, the anti-fastening mechanism 705 will contact the surface of the cable. Through the anti-fastening mechanism 705, the pressure plate 7023 can avoid being pressed down too much, which would cause the cable to be unable to connect.

[0050] Furthermore, the anti-fastening mechanism 705 includes a fixing plate 7051, which is disposed inside the mounting groove. Multiple sets of guide wheels 7052 are provided on one side of the fixing plate 7051, and multiple sets of return springs 7053 are provided on the other side of the fixing plate 7051. One end of the return spring 7053 is disposed on one side of the inner wall of the mounting groove.

[0051] Specifically, such as Figure 6 As shown, when the pressure of the pressure plate 7023 is greater, the fixing plate 7051 will sink into the mounting groove through the return spring 7053. At this time, the multiple sets of guide wheels 7052 will contact the cable. The cable can still slide through the guide wheels 7052, so there will be no situation where it cannot slide. Moreover, the multiple sets of guide wheels 7052 can crush the surface of the armored cable to make it fit better, thereby achieving the effect of fully limiting the cable. It should be noted that the downward pressure of the pressure plate 7023 should not be too great, at most the guide wheels 7052 should be almost completely sinking into the mounting groove.

[0052] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
