Description

Technical Field

[0001] This utility model relates to the field of parallel stranding machine technology, and in particular to a cage mechanism and its parallel stranding machine. Background Technology

[0002] A stranding machine is a type of mechanical equipment that can be widely used to strand various soft / hard conductor wires (copper wire, enameled wire, tinned wire, copper-clad steel, copper-clad aluminum, etc.) and electronic wires (such as power cords, headphone wires, telephone wires, PVC wires, network cables, etc.). Through rotation and tension control, multiple single conductors are twisted into one strand to meet the process requirements of the wire. Parallel stranding machines are a type of stranding machine that mainly uses multiple conductor wires connected in parallel for stranding.

[0003] In the prior art, the wire cage is an important component of the stranding machine. It is mainly used to support the pay-off reel and drive it to rotate synchronously, so as to realize the stranding operation of the conductor wire by using torque. However, the wire cage currently used can only be adapted to pay-off reels of a single size and cannot be used for positioning pay-off reels of multiple sizes. This results in the limitation of the use of the wire cage and makes it difficult to meet diverse usage needs. Utility Model Content

Detailed Implementation

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] This utility model provides, for example Figures 1-6 The image shows a cage frame mechanism.

[0036] Example 1 includes a disc frame 100, a pay-off reel 200, multiple extrusion plates 103, and multiple first guide wheels 112. Multiple drive shafts 102 are rotatably connected to the sidewalls of the disc frame 100 in a circular array. A bobbin shaft 101 is rotatably connected to the outer wall of each drive shaft 102. The pay-off reel 200 is sleeved on the outer wall of the bobbin shaft 101. Multiple extrusion plates 103 are slidably connected to the bobbin shaft 101. A drive mechanism is provided inside the bobbin shaft 101 to drive the extrusion plates 103 to extend and retract on the outer wall of the bobbin shaft 101. Multiple first guide wheels 112 are rotatably arranged in a circular array on the inner sidewall of the disc frame 100. Multiple drive shafts 102 are rotatably mounted on the outer side of the side wall of the tray frame 100 to support the spool shaft 101. Then, multiple retractable extrusion plates 103 are set on the outer peripheral wall of the spool shaft 101. After the pay-off reel 200 is fitted onto the outer wall of the spool shaft 101, the extrusion plates 103 are driven by the drive mechanism to extend or retract on the outer wall of the spool shaft 101. This causes the outer wall of the extrusion plates 103 to press against the inner ring wall of the pay-off reel 200, thereby achieving a self-centering extrusion effect. This allows the pay-off reel 200 to be positioned and fixed on the outer wall of the spool shaft 101. At the same time, different sizes of pay-off reels 200 can be positioned by varying the extension or retraction of the extrusion plates 103.

[0037] The driving mechanism includes an inclined drive plate 109, an inclined push plate 106, and a positioning mechanism. The inclined drive plate 109 is slidably connected to the end face of the bobbin shaft 101. One side of the extrusion plate 103 extends into the interior of the bobbin shaft 101 and is fixedly connected to the outer wall of the inclined push plate 106. The side of the inclined push plate 106 facing away from the extrusion plate 103 is slidably fitted against the inclined surface of the inclined drive plate 109. The positioning mechanism is located at the end of the drive shaft 102 and is used to position the multiple inclined push plates 106 at the end face of the bobbin shaft 101. An inclined baffle 107 is fixedly installed at the end of the inner cavity of the bobbin shaft 101 away from the positioning mechanism. A return spring 108 is fixedly connected between the inclined baffle 107 and the inclined drive plate 109. In the driving mechanism, the inclined drive plate 109 drives the bobbin shaft 101. 1. The inner cavity moves by using the inclined surface of the inclined drive plate 109 in contact with the inclined push plate 106. This allows the inclined drive plate 109 to move inward while simultaneously lifting the extrusion plate 103, causing the extrusion plate 103 to extend. Then, the position of the inclined drive plate 109 is locked and positioned by the positioning mechanism, ensuring the stable support and positioning of the extrusion plate 103 on the pay-off reel 200. This allows pay-off reels of different sizes to reach the top of the outer wall of the spool shaft 101. The reset spring 108 provides an elastic thrust for the extension of the inclined drive plate 109, allowing the inclined drive plate 109 to automatically extend from the spool shaft 101 under external thrust, thus achieving automatic reset of the inclined drive plate 109 for convenient subsequent use.

[0038] The positioning mechanism includes an externally threaded tube 104 and an adjusting turntable 105. The externally threaded tube 104 is rotatably connected to the end of the drive shaft 102, and one end of the externally threaded tube 104 is fixedly connected to the end face of the bobbin shaft 101. The adjusting turntable 105 is threadedly sleeved onto the outer wall of the externally threaded tube 104. One end of the inclined drive plate 109 is movably connected to the end face of the adjusting turntable 105. An annular groove 111 is provided on the side of the adjusting turntable 105 near the inclined drive plate 109. A T-shaped rod 110 is fixedly connected to the end of the inclined drive plate 109 opposite the adjusting turntable 105, and the end of the T-shaped rod 110 is movably connected to the inner cavity of the annular groove 111. By adjusting the threaded connection of the turntable 105 to the outer wall of the external threaded tube 104, the turntable 105 can rotate clockwise or counterclockwise while moving axially along the outer wall of the extrusion plate 103, thereby driving the inclined drive plate 109 into the spool shaft 101. At the same time, the self-locking effect between the external threaded tube 104 and the turntable 105, combined with the elastic thrust of the return spring 108, can lock the position of the inclined drive plate 109, ensuring the stability of the inclined drive plate 109 in lifting the extrusion plate 103, thus ensuring the stability of the wire feeding reel 200 in positioning on the outer wall of the spool shaft 101.

[0039] Example 2: Based on Example 1, a second connecting seat 116 is rotatably connected to the side wall of the first guide wheel 112. The end of the second connecting seat 116 is fixedly connected to the side wall of the disc frame 100. A guide mechanism is provided on the side wall of the disc frame 100, located on the side of the spool shaft 101 near the first guide wheel 112. By providing a guide mechanism between the spool shaft 101 and the first guide wheel 112, the conductor wire can be limited and guided during the unwinding process from the unwinding reel 200, so that the conductor wire can be stably transferred from the first guide wheel 112. This avoids the conductor wire swinging back and forth during unwinding on the unwinding reel 200, which affects the stability of the unwinding process and helps to improve the quality of conductor wire stranding operation.

[0040] The guiding mechanism includes two first connecting seats 115, two guide shafts 113, and two second guide wheels 114. The two first connecting seats 115 are arranged in parallel and spaced apart and fixed to the side wall of the disc frame 100. The two guide shafts 113 are rotatably connected between the two first connecting seats 115 in a parallel and spaced-apart manner. The two second guide wheels 114 are rotatably connected to the side wall of the disc frame 100, and the second guide wheels 114 are located on the side of the guide shaft 113 closer to the first guide wheel 112. The conductor wire on the outer wall of the wire feeding reel 200 flows from the two guide shafts 113. After passing between 13, it enters between the two second guide wheels 114, and finally extends along the outer wall of the first guide wheel 112 towards the axial direction of the disc frame 100. This allows the conductor wire to be initially guided by the two guide shafts 113 when it is laid on the laying reel 200. Then, the conductor wire is guided by the two second guide wheels 114 for secondary guiding. The guiding directions of the second guide wheels 114 and the guide shafts 113 are perpendicular, which can realize the limiting guidance of the conductor wire in two vertical directions, thereby improving the stability of the conductor wire laying process.

[0041] A parallel stranding machine includes the aforementioned cage mechanism.
