Description

Technical Field

[0001] This utility model relates to the technical field of cable pulling devices in the power cord production process, and in particular to a cable pulling device in the power cord production process. Background Technology

[0002] A power cord is an electrical wire that carries electric current. Current is typically transmitted point-to-point. Power cords can be categorized into AC (alternating current) power cords and DC (direct current) power cords based on their application. AC power cords are typically used for transmitting higher voltage alternating current. Due to the higher voltage, these cords require standardized safety certifications before they can be officially manufactured.

[0003] In existing power cord production, a cable pulling machine is used to pull the coiled wires. The wires continuously enter the wire assembly of the pulling machine. At the same time, the end of the pulling machine is equipped with a smooth round tube to prevent the wires from directly rubbing against the edges of the pulling machine. Since the round tube only serves to assist in the transmission of the wires and cannot limit the wires, the wires that swing off the drum may detach from the pulling machine without limiting them, which will affect the continuity of wire delivery. To address this, we provide a cable pulling device for the power cord production process. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing cable traction machines that lack limiting components at the feeding end, and to provide a cable traction device for power cord production.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a cable pulling device for power cord production, comprising: a pulling machine, one end of which is provided with a limiting mechanism, the limiting mechanism including a fixed plate, the fixed plate being fixedly connected to the pulling machine, a bidirectional threaded rod sleeved inside the fixed plate, a guide rod provided on one side of the bidirectional threaded rod, the guide rod being fixedly connected to the fixed plate, a threaded block one sleeved on the outer surface of the bidirectional threaded rod, a threaded block two sleeved on the outer surface of the bidirectional threaded rod, both threaded blocks one and two being threadedly connected to the bidirectional threaded rod, and a connecting frame provided at one end of both threaded blocks one and two, the connecting frame being connected to threaded blocks one... The connecting frame is fixedly connected to the threaded block. A rotating shaft is located inside the connecting frame and is fixedly connected to it. A roller is fitted onto the outer surface of the rotating shaft, and the roller is rotatably connected to the rotating shaft. A sliding frame is located on one side of the connecting frame and is fitted onto the outer surface of the guide rod. The bidirectional threaded rod is rotatably connected to the fixed plate. The sliding frame is fixedly connected to the connecting frame and slidably connected to the guide rod. A bearing is fitted onto the outer surface of one end of the bidirectional threaded rod and is located inside the fixed plate. The bearing is fixedly connected to both the inner wall of the fixed plate and the outer surface of the bidirectional threaded rod. A knob is fixedly connected to one end of the bidirectional threaded rod. An auxiliary mechanism is located at one end of the traction machine. The auxiliary mechanism includes two uprights, which are fixedly connected to the traction machine. A fixed shaft is located on the inner side of each upright and is fixedly connected to it. A roller is fitted onto the outer surface of the fixed shaft and is rotatably connected to it. A limiting tube is fitted onto the outer surface of each upright and is fixedly connected to it.

[0006] Compared with the prior art, the advantages and positive effects of this utility model are as follows: This invention, by setting a limiting mechanism, can limit the wire entering the traction machine, thus preventing the wire from detaching from the wire assembly of the traction machine and ensuring continuous wire transmission. At the same time, the limiting mechanism can also assist in the transmission of the wire, preventing the wire from rubbing against the edges and corners of the traction machine, thereby protecting the wire's insulation layer from damage. The invention also features a bidirectional threaded rod that can drive threaded blocks one and two simultaneously in opposite directions, allowing the rollers in a relative state to move closer to each other, limiting and assisting in the transmission of the wire. Furthermore, the auxiliary mechanism ensures that the wire is also protected and limited when it detaches from the traction machine, preventing it from rubbing against the edges and corners of the traction machine.

[0012] 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.

[0013] Example

[0014] As shown in Figures 1-3, this utility model provides a technical solution: a cable pulling device in the production process of power cords, comprising: a pulling machine 1, a limiting mechanism 2 at one end of the pulling machine 1, the limiting mechanism 2 including a fixed plate 21, the fixed plate 21 being fixedly connected to the pulling machine 1, a bidirectional threaded rod 22 sleeved inside the fixed plate 21, a guide rod 23 on one side of the bidirectional threaded rod 22, the guide rod 23 being fixedly connected to the fixed plate 21, a threaded block 24 sleeved on the outer surface of the bidirectional threaded rod 22, a threaded block 25 sleeved on the outer surface of the bidirectional threaded rod 22, both threaded blocks 24 and 25 being threadedly connected to the bidirectional threaded rod 22, a connecting frame 26 at one end of each threaded block 24 and 25, the connecting frame 26 being fixedly connected to the threaded blocks 24 and 25, a rotating shaft 27 inside the connecting frame 26, the rotating shaft 27 being fixedly connected to the connecting frame 26, the rotating shaft 27... Rollers 28 are fitted onto the outer surface of the connecting frame 26, and the rollers 28 are rotatably connected to the rotating shaft 27. A sliding frame 29 is provided on one side of the connecting frame 26, and the sliding frame 29 is fitted onto the guide rod 23. The outer surface of the double-threaded rod 22 is rotatably connected to the fixed plate 21, the sliding frame 29 is fixedly connected to the connecting frame 26, the sliding frame 29 is slidably connected to the guide rod 23, a bearing 201 is sleeved on the outer surface of one end of the double-threaded rod 22, the bearing 201 is placed inside the fixed plate 21, the bearing 201 is fixedly connected to the inner wall of the fixed plate 21 and the outer surface of the double-threaded rod 22, and a knob 202 is fixedly connected to one end of the double-threaded rod 22.

[0015] In this embodiment, a connecting frame 26 is provided, and a rotating shaft 27 is fixedly connected inside the connecting frame 26. The rotating shaft 27 allows the rollers 28 to rotate, so that the wire can pass through the rollers 28 with minimal resistance, which assists in the transmission of the wire. At the same time, the two rollers 28 that are close to each other can limit the wire, so that the wire will not deviate and will not detach from the traction machine 1. A bidirectional threaded rod 22 is provided, which can drive the threaded block 1 24 and the threaded block 25, so that the threaded block 1 24 and the threaded block 25 can move towards each other simultaneously, thereby driving the two sets of rollers 28 simultaneously and gradually bringing them closer together, so as to achieve the purpose of limiting and assisting the transmission of the wire. A guide rod 23 and a sliding frame 29 are provided to guide the threaded block 1 24, the threaded block 25 and the connecting frame 26, so that they can move up and down normally.

[0016] Example

[0017] As shown in Figure 1 and Figure 4 As shown, one end of the traction machine 1 is provided with an auxiliary mechanism 3. The auxiliary mechanism 3 includes two uprights 31. The uprights 31 are fixedly connected to the traction machine 1. The inner side of the uprights 31 is provided with a fixed shaft 32, which is fixedly connected to the uprights 31. The outer surface of the fixed shaft 32 is fitted with a roller tube 33, which is rotatably connected to the fixed shaft 32. The outer surface of the uprights 31 is fitted with a limit tube 34, which is fixedly connected to the uprights 31.

[0018] In this embodiment, by setting an auxiliary mechanism 3, the wire conveyed from the traction machine 1 can be limited. A fixed shaft 32 and a roller tube 33 are set, and the roller tube 33 can rotate around the fixed shaft 32. When the wire passes through the roller tube 33, the roller tube 33 can rotate to assist in conveying the wire. A limiting tube 34 is set to limit the wire so that the wire will not detach from the outlet end of the traction machine 1.

[0019] Working principle: As shown in Figure 1- Figure 4As shown, when using this utility model, if it is necessary to process the coiled wire, the traction machine 1 can be used for traction and transmission. At this time, the knob 202 is turned, and the knob 202 will drive the bidirectional threaded rod 22 to rotate. The bidirectional threaded rod 22, with the cooperation of the bearing 201, drives the threaded block 1 24 and the threaded block 25 to drive the connecting frame 26 to move in opposite directions until the two sets of rollers 28 can make slight contact with the wire. This ensures that the wire will not detach from the traction machine 1 under the transmission of the rollers 28. When the wire is pulled by the wire assembly of the traction machine 1, the wire will drive the rollers 28 to rotate. The rollers 28 can rotate around the rotating shaft 27, which reduces the transmission resistance of the wire. After that, when the wire comes out from the output end of the traction machine 1, it will contact the roller tube 33 and drive the roller tube 33 to rotate around the fixed shaft 32. It rotates and, under the limit of the limit tube 34, enters other processing equipment, and finally produces the power cord.

[0020] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
