Description

Technical Field

[0001] The utility model relates to the technical field of cable stranding machine protection, in particular to a cable stranding machine with a protection mechanism. Background Art

[0002] Cable stranding machines are key equipment in cable production. They twist multiple single wires together to form cables with specific properties and structures. They have high working efficiency and can accurately control the pitch and tension of the twisting to ensure stable cable quality. In the power, communications and other industries, cable stranding machines play an important role, providing a reliable transmission medium for various projects.

[0003] Traditional cable stranding machines often face problems such as wire damage, equipment wear, and low production efficiency when stranding conductor wires. Especially during high-speed stranding, due to the large pulling force on the wires, the wires are prone to breakage and damage during the stranding process, and even cause equipment failure, affecting production safety and efficiency. For this reason, a cable stranding machine with a protective mechanism is designed. Utility Model Content

[0022] 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 the embodiments.

[0023] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0024] Reference Figures 1-6A cable stranding machine with a protective mechanism comprises a base plate 1, a cable stranding machine 2 is arranged on the top of the base plate 1, a bracket 201 is fixedly connected to the bottom of the cable stranding machine 2, and the outer sides of the two brackets 201 at both ends are fixedly connected to the same arc-shaped fixed rod 3, and the tops of the two arc-shaped fixed rods 3 are fixedly connected to the same top plate 4, and the two ends on both sides of the middle of the top plate 4 are fixedly connected to vertical rods 14, and the surfaces of the two vertical rods 14 on the same side are slidably sleeved with U-shaped blocks 16, and each U-shaped block 16 has two square holes adapted to the vertical rods 14, and the tops of the four vertical rods 14 are fixedly connected to the same fixing ring 15, and the surfaces of the four vertical rods 14 are slidably sleeved with the same lifting block 17, and the four corners of the lifting block 17 are provided with square holes adapted to the vertical rods 14.

[0025] In this embodiment, a servo motor 18 is fixedly connected to the middle of the top of the lifting block 17, and the output end of the servo motor 18 at the bottom passes through the lifting block 17 and is fixedly connected to an equilateral triangle plate 19, and the equilateral triangle plate 19 is adapted to the two U-shaped blocks 16. By rotating the equilateral triangle plate 19, one of the U-shaped blocks 16 can be lifted, or both U-shaped blocks 16 can be lifted at the same time.

[0026] In this embodiment, both sides of the top plate 4 are rotatably connected to the protective nets 5, and the middle of the top of each protective net 5 is rotatably connected to the second connecting rod 13, and the other end of each second connecting rod 13 is rotatably connected to the inner side of the adjacent U-shaped block 16.

[0027] In this embodiment, vertical plates 8 are fixedly connected to the top of the top plate 4 near both ends, and the same bidirectional screw rod 9 is rotatably connected between the two vertical plates 8. A drive motor 10 is fixedly connected to the outer side of one of the vertical plates 8, and the output end of the drive motor 10 passes through the side vertical plate 8 and is fixedly connected to one end of the bidirectional screw rod 9.

[0028] In this embodiment, both ends of the bidirectional screw rod 9 are screwed with screw blocks 11, and each screw block 11 is fixedly sleeved with a screw nut that is compatible with the screw block 11. The tops of the two screw blocks 11 are rotatably connected to the first connecting rod 12, and the other end of each first connecting rod 12 is rotatably connected to one side of the lifting block 17. The two screw blocks 11 are driven by the driving motor 10 to approach each other, thereby realizing the lifting of the lifting block 17.

[0029] In this embodiment, each protective net 5 is fixedly connected to a connecting plate 7 on both sides of the bottom, and a stop block 701 is fixedly connected to the bottom of the adjacent end of the two connecting plates 7 on the same side, and the adjacent side of the two connecting plates 7 on the same side is rotatably connected to a rotating rod 702, and the other end of the two rotating rods 702 on the same side is rotatably connected to the same protective plate 6. Through the arrangement of the connecting plate 7, the rotating rod 702 and the protective plate 6, when the two protective nets 5 are providing protection, the protective plate 6 can further block the cable twisting machine 2 and the protective net 5 to prevent users from close contact with the cable twisting machine 2.

[0030] Working principle: When in use, the cable twisting machine 2 is blocked by the setting of two protective nets 5, so that the user cannot get close to the cable twisting machine 2 when the cable twisting machine 2 is working. At the same time, when the two protective nets 5 are protecting, the rotating rods 702 on both sides will be unfolded and level with the ground. Under the action of the protective plate 6, the user can maintain a safe distance from the cable twisting machine 2 and the protective net 5, further protecting the user's safety. When the cable twisting machine 2 needs to be operated and one side 5 needs to be opened, the servo motor 18 is started so that one corner of the equilateral triangle plate 19 faces the U-shaped block 16 of the protective net 5 on that side. At this time, the equilateral triangle plate 19 will not contact the bottom of the U-shaped block 16 on the other side, and the drive is started. The motor 10 is driven to make the two screw blocks 11 approach each other. The lifting block 17 rises through the setting of the two first connecting rods 12. At the same time, under the action of the equilateral triangle plate 19, the U-shaped block 16 on that side rises accordingly, and the second connecting rod 13 is used to unfold the protective net 5 on that side, while the other protective net 5 will not unfold. Similarly, the protective net 5 on the other side can also be unfolded. When it is necessary to unfold the two protective nets 5 at the same time, the servo motor 18 is started so that one corner of the equilateral triangle plate 19 is facing the driving motor 10. At this time, the other two corners are protruding from the bottom of the two U-shaped blocks 16. When the driving motor 10 is started, the two U-shaped blocks 16 can be driven to rise, thereby making the two protective nets 5 unfold synchronously.
