Description

Technical Field

[0001] This invention relates to the field of automatic cable feeding, and more specifically, to an automatic cable feeding and straightening device. Background Technology

[0002] Cables are a general term for items such as optical cables and electrical cables. Cables have many uses, primarily for control installation, equipment connection, and power transmission, making them a common and indispensable part of daily life. The core of power cables is typically made of multi-strand copper or aluminum conductive material. During production or transportation, cables are usually wound on spools for convenient storage and transfer, requiring manual straightening by operators during installation. Due to the high hardness and toughness of cables, manual straightening is inefficient, and the straightness often fails to meet requirements, resulting in poor appearance quality. Chinese invention patent application number 201511022528X discloses a straightening machine for straightening large-diameter cables, including a pre-detection and straightening device for the cable feeding mechanism. However, this technology only solves some problems in the cable straightening process and cannot effectively address the issue of maintaining the overall centerline of the cable during processing cables of different diameters. This invention focuses on solving this problem to improve the efficiency of the cable feeding and straightening process. Summary of the Invention

[0003] The purpose of this invention is to solve the problem of low processing efficiency and inability to keep the center line of cables of different diameters constant in existing cable straightening technology. It proposes an automatic cable feeding and straightening device, which greatly improves the efficiency of cable feeding and straightening by adding a feeder to keep the center of the cable constant during the feeding process.

[0004] The present invention achieves the above-mentioned objective through the following technical solution: an automatic cable feeding and straightening device, comprising a workbench, an inlet guide device, two sets of feeders, and two sets of straighteners. The feeders include an inlet feeder and an outlet feeder with identical structures. The straighteners include a horizontal straightener and a vertical straightener with identical structures but perpendicular to each other. The inlet guide device, inlet feeder, horizontal straightener, vertical straightener, and outlet feeder are fixed on the workbench in sequence from front to back. The cable passes through the inlet guide device, inlet feeder, horizontal straightener, and vertical straightener in sequence and then extends out from the outlet feeder.

[0005] Furthermore, the inlet guiding device includes a horizontal guide tube, a guide tube fixing frame, and a vertical support. The horizontal guide tube is horizontally installed on the guide tube fixing seat at the front end of the guide tube fixing frame. The rear end of the guide tube fixing frame is fixed to the vertically set vertical support by bolts. The lower end of the vertical support is fixed to the worktable.

[0006] Furthermore, the guide tube fixing seat at the front end of the guide tube fixing frame is provided with a circular clamping hole. The horizontal guide tube passes through the circular clamping hole on the guide tube fixing seat and is positioned by the positioning bolts provided on the side of the circular clamping hole. The rear end of the guide tube fixing frame is connected to the vertical support through a movable sleeve. The movable sleeve is provided with a horizontal through hole in the horizontal direction and a vertical through hole in the vertical direction. The rear end of the guide tube fixing frame passes through the horizontal through hole and is positioned by the positioning bolts provided on the side of the horizontal through hole. The upper end of the vertical support passes through the vertical through hole and is positioned by the positioning bolts provided on the side of the vertical through hole.

[0007] When needed, loosen the positioning bolts on the circular clamping holes, and the horizontal guide tube moves back and forth and is positioned by the positioning bolts, adjusting the distance between the horizontal guide tube and the inlet feeder. The height and left-right position of the horizontal guide rod can be adjusted through the horizontal and vertical through holes, thus achieving adjustment of the horizontal guide rod to any position.

[0008] Furthermore, the feeder includes a feeder support plate, a feeder motor mounting plate, a first isolation plate, a second isolation plate, a lead screw drive motor, a feeder drive motor, a feeder ball screw, a first driving pulley, a first driven pulley, a first synchronous belt, a feeder lead screw nut, a second driving pulley, a second driven pulley, a second synchronous belt, gears, a drive shaft, a drive roller, a fixed roller, a roller support seat, a vertical slide seat, a feeder slider, and a lead screw nut seat. The feeder motor mounting plate is vertically mounted on one side of the feeder support plate. The first isolation plate and the second isolation plate are arranged parallel to each other with the feeder support plate. One end of the first isolation plate is fixed to one end of the feeder motor mounting plate, and one end of the second isolation plate is fixed between the first isolation plate and the feeder support plate. On the side of the feed motor mounting plate; the feed ball screw is vertically arranged and fixed to the feed support plate by two screw seats. A second driven pulley is provided at one end of the feed ball screw. The screw drive motor is fixed to the feed support plate by a motor base. A second driving pulley is connected to the motor head of the screw drive motor. The second driving pulley and the second driven pulley are connected by a second synchronous belt. Two screw nut seats are provided, each with a feed ball screw nut. The feed ball screw nut has a threaded through hole that mates with the feed ball screw. Both screw nut seats are fitted onto the feed ball screw by the feed ball screw nut. Each screw nut seat is fixedly connected to a roller support seat. Both ends of the ball screw are equipped with wire feeding sliders. Two vertical sliding groove seats are provided on the wire feeding support plates on both sides of the ball screw. The wire feeding sliders at both ends of the roller support seats are fitted into the two vertical sliding groove seats. When the screw drive motor moves, it drives the wire feeding ball screw through a synchronous belt mechanism consisting of a second driving pulley, a second driven pulley, and a second synchronous belt. This, in turn, drives the entire assembly of the screw nut seat and roller support seats to move up and down. Each roller support seat has a fixed roller, and two drive rollers are located next to the two fixed rollers. Each drive roller is connected to a drive shaft. The middle of the two drive shafts is supported on the two roller support seats by bearings. The other end of the drive shaft is connected to an intermediate shaft via a first universal joint. One end of the intermediate shaft is connected to the gear shaft via a universal joint. The gear shaft is supported on the first and second isolation plates by two bearings. The portions of the two gear shafts located between the first and second isolation plates are fitted with meshing gears. One of the gear shafts passes through the second isolation plate, and a first driven pulley is provided at the end of the gear shaft that passes through the second isolation plate. The transmission line drive motor is fixed on the transmission line motor mounting plate, and a first driving pulley is installed at the head of the transmission line drive motor. The first driven pulley and the first driving pulley are connected by a first synchronous belt. When the transmission line drive motor moves, it drives the two drive shafts to rotate in opposite directions through the synchronous belt mechanism composed of the first driven pulley, the first driving pulley, and the first synchronous belt, thereby driving the two drive rollers to rotate in opposite directions.

[0009] Furthermore, the straightener includes a straightening support plate, a first straightening wheel set, a second straightening wheel set, a straightening wheel support seat, a straightening slider, a straightening guide rail, a straightening screw, a straightening drive motor, a straightening screw nut, a straightening drive pulley, a straightening driven pulley, and a straightening synchronous belt. The straightening support plate is fixed on the workbench, and two straightening guide rails are arranged parallel to each other on the straightening support plate. The two ends of the straightening screw are connected to the straightening support plate through screw seats, and a straightening driven pulley is provided at one end of the straightening screw. The straightening drive motor is fixed to the straightening support plate through a motor seat, and a straightening drive pulley is provided at the movable end of the straightening drive motor. The straightening drive pulley and the straightening driven pulley are connected by a straightening synchronous belt. The straightening wheel support is provided in two parts. The first straightening wheel group and the second straightening wheel group are respectively installed on the two straightening wheel support seats. Each straightening wheel support seat has a straightening slider at both ends of its bottom. The bottom of each straightening wheel support seat is fitted onto two straightening guide rails through the straightening slider. Each straightening wheel support seat is also connected to a straightening screw nut. The threads of the two straightening screw nuts are opposite, and both straightening screw nuts are fitted onto the straightening screw. When the straightening drive motor moves, it drives the straightening screw to rotate through the synchronous belt mechanism composed of the straightening driving pulley, the straightening driven pulley, and the straightening synchronous belt. In turn, the two straightening screw nuts drive the two straightening wheel support seats to approach or separate from each other.

[0010] Furthermore, both the first straightening wheel group and the second straightening wheel group include multiple straightening wheels arranged in a straight line along the wire feeding direction at equal intervals, and the straightening wheels of the first straightening wheel group and the second straightening wheel group are staggered.

[0011] Furthermore, each straightening wheel in the first and second straightening wheel sets is provided with a U-shaped groove along its axial direction. The U-shaped groove is used to fit the cable to accommodate the straightening and transmission of cables with different diameters.

[0012] Furthermore, the roller support seat is provided with a square groove with a side length slightly larger than the diameter of the drive roller. When the two roller support seats are separated by the action of the lead screw drive motor, the two drive rollers not only follow the roller support seats up and down, but also move along the axis towards the direction groove.

[0013] When the screw nut seat and roller support seat move up and down as a whole, the two drive rollers follow the up and down movement of the two roller support seats. The drive shafts of the two drive rollers can move slightly within the roller support seats along the axis of rotation. The first and second universal joints ensure that the drive rollers can rotate normally. The depth of the square groove ensures that the two drive rollers will not touch the bottom of the square groove when the two roller support seats move to their limit positions.

[0014] Furthermore, the horizontal straightener is also equipped with a lifting device, which includes a lifting support plate, lifting slide rails, lifting sliders, a lifting motor, a lifting movable plate, and a horizontal support rod. The lifting motor is fixed to the straightening support plate of the horizontal straightener, the lifting movable plate is fixed to the movable head of the lifting motor, the horizontal support rod is horizontally positioned with one end fixed to the lifting movable plate, and the other end of the lifting support rod passes through two adjacent straightening wheels and extends to the lower end of the transmission cable. The lifting support plate is vertically fixed to the straightening support plate of the horizontal straightener, and two lifting slide rails are vertically fixed to the lifting support plate. The two ends of the lifting movable plate are provided with lifting slide rails that cooperate with the lifting slide rails. The lifting movable plate is fitted onto the two lifting slide rails by two lifting sliders. When the lifting motor moves, it drives the horizontal support rod to move up and down along the lifting slide rails through the lifting movable plate.

[0015] The horizontal support plate prevents the cables from sagging due to gravity during transport.

[0016] The beneficial effects of this invention are as follows:

[0017] 1. This invention automates cable straightening and transmission by setting up an inlet feeder, an outlet feeder, a horizontal straightener, and a vertical straightener. The whole process is highly efficient, requires no manual labor, and has high straightening accuracy.

[0018] 2. Both the cable feeder and the straightener of the present invention are adjustable in width, and the straightening wheel has a U-shaped groove around its periphery, which can adapt to the straightening processing of cables with different traps.

[0019] 3. The center lines of the straightener and the cable feeder of this invention are both located on the same straight line, and the center of gravity of the straightener and the cable feeder is adjustable, so that the overall center line remains unchanged during the straightening process of cables of different diameters.

[0020] 4. The present invention uses horizontal and vertical straighteners that are perpendicular to each other, so that the whole device can straighten cables in multiple directions. The two feeders are distributed in front and behind to ensure that there is always power in the entire cable transmission process, thus ensuring the transmission of the cable during the straightening process.

[0021] 5. This invention achieves variable angle power transmission through a universal joint to adapt to the up-and-down movement of the drive rollers of the wire feeder when they are separated, thus realizing the adjustable up-and-down position of the wire feeder assembly.

[0022] 6. This invention uses horizontal support rods to support the lower end of the cable, preventing the cable from sag due to gravity. Attached Figure Description
