Description

Technical Field

[0001] This utility model relates to the field of wire feeding device technology, specifically a tension wire feeding device with variable torque. Background Technology

[0002] Cable unwinding devices are commonly used equipment in cable processing and production. A cable reel is mounted on the unwinding device. When the cable needs to be retrieved, pulling the cable on the reel causes it to rotate on the unwinding device, releasing the cable and allowing it to be removed from the reel. This method is convenient to use.

[0003] In current cable laying devices, the laying reel is rotated to lay or reel in the cable. However, the position of the reel's axis and the rotating handle is usually constant. When laying or reeling in cables of different thicknesses, the distance of the rotating handle cannot be adjusted, resulting in poor performance.

[0004] Therefore, we propose a variable torque tension wire feeding device to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to solve the aforementioned technical problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a variable torque tension wire feeding device, comprising a mounting plate and a crossbeam fixed to the side of the mounting plate, a wire reel rotatably mounted on one end of the crossbeam, a slide rail fixed to the side of the wire reel, and a sliding seat slidably mounted on the slide rail, and a wrench for rotating the wire reel fixed to one end of the sliding seat.

[0007] Furthermore, the slide rail is provided with a plurality of locking holes at equal intervals along its length, the sliding seat is provided with mounting holes, and the mounting holes are fitted with locking bolts that cooperate with the locking holes.

[0008] Furthermore: one end of the crossbeam is fixed with a rotating drum, and a rotating shaft is rotatably mounted inside the rotating drum via a bearing, and the rotating shaft is fixed at the axis of the coiling reel.

[0009] Furthermore: one end of the rotating shaft passes through the rotating cylinder and is fixed with a ratchet, and one side of the crossbeam is provided with ratchet teeth that cooperate with the ratchet.

[0010] Furthermore, a protective shell is installed on one side of the crossbeam, and the ratchet is located inside the protective shell.

[0011] Furthermore, the outer surface of the upper part of the protective shell is symmetrically fixed with rotating supports, and the ratchet is rotatably installed between the two rotating supports.

[0012] Furthermore, the outer surface of the protective shell is equidistantly equipped with several mounting seats along the circumferential direction, and the mounting seats are equipped with fixing bolts that cooperate with the crossbeam.

[0013] The beneficial effects of this utility model are: The wrench of this invention is connected to the reel in a sliding manner. When winding or unwinding thicker or heavier cables, the wrench can move away from the axis of the reel, thereby changing the torque. When unwinding or winding thicker or heavier cables, the reel can be rotated with less force, which is convenient for workers. When winding or unwinding thinner or lighter cables, the wrench can move towards the axis of the reel, so that the wrench and the axis of the reel are closer. When winding or unwinding thinner or lighter cables, the rotation amplitude is smaller, and the winding or unwinding efficiency is higher. Attached Figure Description

[0016] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0017] A variable torque tension cable feeding device includes a mounting plate 1, which serves to install the cable feeding device. A crossbeam 2 is fixed to one side of the mounting plate 1, and a rotating drum 9 is fixed to the end of the crossbeam 2 away from the mounting plate 1. A rotating shaft 11 is rotatably mounted inside the rotating drum 9 through a bearing 10, allowing the rotating shaft 11 to rotate smoothly inside the rotating drum 9. One end of the rotating shaft 11 is fixedly connected to the axis of a coiling reel 3. The coiling reel 3 enables the cable feeding or winding operation.

[0018] One end of the rotating shaft 11 passes through the crossbeam 2 and is fitted with a ratchet 12. The ratchet 12 is located inside the protective housing 14. The protective housing 14 protects the ratchet 12 and prevents it from being damaged by collision. Two rotating supports 15 are fixed to the upper outer surface of the protective housing 14. The same ratchet 13 is rotatably mounted between the two rotating supports 15. When the ratchet 13 rotates downward, it locks the ratchet 12, so that the rotating shaft 11 can only rotate in one direction.

[0019] It should be noted that: several mounting seats 16 are equidistantly installed on the outer surface of the protective shell 14 along the circumferential direction. Each mounting seat 16 is equipped with a fixing bolt connected to the crossbeam 2, so that the protective shell 14 can be disassembled to facilitate the maintenance of the ratchet 12.

[0020] The side of the reel 3 is fixed with a slide rail 4, and a sliding seat 5 is slidably installed on the slide rail 4. A wrench 6 is installed on the sliding seat 5. Through the cooperation of the slide rail 4 and the sliding seat 5, the wrench 6 can be slidably adjusted to change the torque, which is suitable for winding or unwinding cables of different thicknesses.

[0021] The slide rail 4 has several locking holes 7 evenly spaced along its length. The sliding seat 5 has a mounting hole, and a locking bolt 8 that mates with the locking hole 7 is installed inside the mounting hole. The locking bolt 8 and the locking hole 7 work together to lock the wrench 9 and prevent the wrench 9 from sliding during use.

[0022] When tightening a thicker or heavier cable: first adjust the position of the wrench 6; then rotate the cable reel 3 and tighten the cable. When adjusting the wrench 6, first loosen the locking bolt 8. After the locking bolt 8 disengages from the inside of the locking hole 7, the sliding seat 5 can slide on the slide rail 4 and drive the wrench 6 to move. When the wrench 6 is adjusted to a position far away from the axis of the coiled thread wheel 3, tighten the locking bolt 8 again to lock the sliding seat 5. Since the wrench 6 is far away from the axis of the coiled thread wheel 3, it is easier to rotate the coiled thread wheel 3, reducing the workload of the workers.

[0023] When tightening the cable: First, rotate the wrench 6 clockwise; the wrench 6 can drive the coil wheel 3 to rotate clockwise, and the coil wheel 3 can tighten the cable during rotation; during the rotation of the coil wheel 3, the rotating shaft 11 can drive the ratchet 12 to rotate, and during the rotation of the ratchet 12, it can repeatedly push the ratchet 13 upward, so that the ratchet 13 can rotate around the axis of the rotating support 15. If the ratchet 13 rotates in the opposite direction, it can lock the ratchet 12.

[0024] When loosening the cable: First, turn the ratchet 13 upwards. If the ratchet 13 disengages from the ratchet 12, rotate the wrench 6 in the opposite direction so that the wrench 6 can drive the coil wheel 3 to rotate in the opposite direction. During the reverse rotation of the coil wheel 3, the cable can be released.

[0025] When laying out thinner and lighter cables: first adjust the position of wrench 6, then tighten or loosen the thinner and lighter cables. When adjusting the wrench 6: First, loosen the locking bolt 8. After the locking bolt 8 disengages from the locking hole 7, the sliding seat 5 drives the wrench 6 to move towards the axis of the coil wheel 3. After adjustment, use the locking bolt 8 again. The locking bolt 8 is threaded into the corresponding locking hole 7, thereby achieving the locking function. Since the distance between the wrench 6 and the axis of the coil wheel 3 is relatively close, the rotation amplitude of the wrench 6 is relatively small during the rotation of the coil wheel 3, and the efficiency of tightening or loosening the cable is also relatively high.

[0026] When tightening or loosening thinner or lighter cables, perform the same operation as described above.
