Description

Technical Field

[0001] This utility model belongs to the field of cable reels, and specifically relates to a double-roller reel for cable winding. Background Technology

[0002] Cable winding is the process of winding the manufactured cable onto a cable reel in an orderly manner. This is the last critical step in cable manufacturing. It not only facilitates the storage and transportation of the cable but also ensures that the cable's performance is not affected during subsequent use, protecting it from damage and maintaining its properties.

[0003] Existing cable reels typically use a motor to rotate them. After the cable is wound, the reel is removed for subsequent cutting during construction. While the reel's spool shape facilitates manual rolling for short-distance movement, pulling the cable requires lifting it off the ground using a support frame. The reel needs to rotate to pull the cable, but its large size and weight make manual lifting inconvenient and hinder cable retrieval. Utility Model Content

[0004] The purpose of this invention is to provide a double-roller type reel for cable winding, which solves the problem of the unnecessary condition of needing to lift the cable reel and use a support frame to pull the cable.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A double-roller reel for cable winding includes an inner reel with identical outer rollers fixed at both ends. An outer reel is sleeved around the inner reel, and identical inner rollers are fixed at both ends of the outer reel. The two inner rollers are located on the inner sides of the two outer rollers, and roller positioning devices are installed on the outer sides of the two outer rollers to enable individual or synchronous rotation of the outer and inner rollers. The inner reel has a hexagonal central hole, and the outer sides of the two outer rollers each have concentric circular grooves. Positioning holes A are distributed circumferentially on the two outer rollers. The roller has positioning holes B distributed around its circumference. Positioning holes A and B can be overlapped and correspond to each other. The circular groove has spring grooves distributed around its circumference, and a spring is placed in each spring groove. The roller positioning device is located in the circular groove and includes a pressure ring and a screw ring from the inside out. The pressure ring is located at the outer end of the spring. A positioning pin corresponding to positioning hole A is fixed on the inner side of the pressure ring. The positioning pin is inserted into positioning holes A and B. The outer side of the pressure ring is always in contact with the inner side of the screw ring through the spring. The screw ring is threadedly connected to the circular groove.

[0007] Preferably, the outer surface of the screw ring is provided with anti-slip grooves.

[0008] Preferably, the outer roller is bolted to one end of the limiting plate, and the other end of the limiting plate is located on the outer side of the screw ring.

[0009] Preferably, two bearings are installed between the outer roll and the inner roll shaft, with the two bearings located at both ends of the inner side of the outer roll.

[0010] Preferably, two support devices are fixed radially on the outer sides of the two outer rollers.

[0011] Preferably, the included angle between the two support devices on the same outer roller is in the range of 60-90°.

[0012] Preferably, the support device includes a telescopic cylinder, a positioning bolt, a telescopic column, an adjusting hole, an adjusting bolt, and a support plate. The telescopic cylinder is radially fixed to the circular groove by the positioning bolt. The telescopic cylinder is closed at one end facing the center of the outer roller and open at the other end. The telescopic cylinder is slidably connected to the telescopic column inside. The telescopic column has multiple adjusting holes on its outer side. An adjusting bolt is installed on the telescopic cylinder and is threadedly connected to any adjusting hole. A support plate is hinged to the outer end of the telescopic column.

[0013] Preferably, the bottom surface of the support plate is fixed with an anti-slip pad.

[0014] This utility model has the following beneficial effects:

[0015] 1. The outer and inner rollers can rotate synchronously through the roller positioning device, which facilitates the winding of the cable by the motor during cable production. After the winding device is removed from the motor and placed on the ground, the outer and inner rollers can also rotate independently through the roller positioning device. The outer roller can be fixed to the ground by hand to prevent it from rolling. When pulling the cable, the inner roller and the outer drum rotate. The cable can be pulled without the need for a support frame, making it extremely convenient to use.

[0016] 2. The support device can extend and retract the support plate to support the ground. It can prevent the outer roller from rolling without manual assistance, so that the cable can be pulled up and used. When moving the cable reel, the telescopic column of the support device retracts to ensure the rolling of the outer roller. Attached Figure Description

[0026] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0027] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] Example 1

[0029] like Figure 1-6As shown, in this embodiment, a double-roller reel for cable winding includes an inner reel 1. Identical outer rollers 2 are fixed to both ends of the inner reel 1, enabling synchronous rotation of the inner reel 1 and the outer rollers 2. An outer reel 3 is fitted over the inner reel 1 for winding the cable. Identical inner rollers 4 are fixed to both ends of the outer reel 3, enabling synchronous rotation of the outer reel 3 and the inner rollers 4. The diameter of the inner rollers 4 is slightly smaller than the diameter of the outer rollers 2. The two inner rollers 4 are located on the inner sides of the two outer rollers 2, respectively. Roller positioning devices 5 are installed on the outer sides of the two outer rollers 2, enabling individual or synchronous rotation of the outer rollers 2 and the inner rollers 4. A hexagonal central hole 11 is opened in the center of the inner reel 1, facilitating the rotation of the cable reel by inserting a motor shaft into the central hole 11 during cable production. The outer sides of the two outer rollers 2 are respectively centered. The circular groove 21 has two outer rollers 2 with positioning holes A22 distributed around their circumference, and two inner rollers 4 with positioning holes B41 distributed around their circumference. The positioning holes A22 and B41 can overlap and correspond. The circular groove 21 also has a spring groove 23 distributed around its circumference, and a spring 24 is placed in the spring groove 23. The roller positioning device 5 is located in the circular groove 21 and includes a pressure ring 51 and a screw ring 52 from the inside out. The pressure ring 51 is located at the outer end of the spring 24. The inner side of the pressure ring 51 is fixed with a positioning pin 511 corresponding to the positioning hole A22. The positioning pin 511 can be inserted into the positioning hole A22 and the positioning hole B41 by axial movement. The outer side of the pressure ring 51 is always in contact with the inner side of the screw ring 52 through the spring 24. The screw ring 52 is threadedly connected to the circular groove 21.

[0030] In a specific implementation, the screw ring 52 is manually rotated and threaded into the circular groove 22, enabling axial movement of the screw ring 52. Due to the outward force of the spring 24 on the pressure ring 51, the pressure ring 51 also moves axially along with the screw ring 52. At the same time, the positioning pin 511 can be inserted into and disengaged from the positioning hole A22 and the positioning hole B41, realizing the synchronous rotation or individual rotation of the outer roller 2 and the inner roller 4. This satisfies the requirement that during the cable production process, the cable reel rotates simultaneously, driven by the motor rotation, which drives the inner winding shaft 1 and the outer winding drum 3. It also allows the cable reel to be rolled by the outer roller 2 after being removed, making it easy to move to a designated position. Alternatively, by fixing the outer roller 2, the inner roller 4 and the outer winding drum 3 can be rotated, allowing the cable to be pulled without a support frame, making it extremely convenient to use.

[0031] The outer side of the screw ring 52 is provided with anti-slip grooves 521, which apply friction to the outer side of the screw ring 52, making it easy to manually turn the screw ring 52.

[0032] The outer roller 2 is bolted to one end of the limiting plate 53, and the other end of the limiting plate 53 is located on the outer side of the screw ring 52, which applies a limiting effect to the screw ring 52 to prevent the screw ring 52 from being screwed out of the outer roller 2.

[0033] Two bearings 31 are installed between the outer drum 3 and the inner shaft 1. The two bearings 31 are located at both ends of the inner side of the outer drum 3 to reduce the friction when the outer drum 3 and the inner shaft 1 rotate.

[0034] Example 2

[0035] To facilitate easy cable retrieval from the ground using the outer roller 2 without requiring manual fixing, improvements were made to embodiment 1, such as... Figure 7-8 As shown, two support devices 6 are fixed radially to the outer surfaces of the two outer rollers 2. The included angle between the two support devices 6 on the same outer roller 2 ranges from 60° to 90°. To satisfy the front and rear support angles of the outer roller 2, the support device 6 includes a telescopic cylinder 61, a positioning bolt 62, a telescopic column 63, an adjustment hole 64, an adjustment bolt 65, and a support plate 66. The telescopic cylinder 61 is radially fixed to the circular groove 21 by the positioning bolt 62, ensuring the position of the telescopic cylinder 61 is fixed. The telescopic cylinder 61 is closed at one end facing the center of the outer roller 2 and open at the other end. The telescopic cylinder 61 is slidably connected to the telescopic column 63 to achieve telescopicity, allowing the outer roller 2 to roll on the ground and facilitating placement. The outer side of the telescopic column 63 has multiple adjustment holes 64, and an adjustment bolt 65 is installed on the telescopic cylinder 61. The adjustment bolt 65 is threaded to any adjustment hole 64, allowing the telescopic column 63 to extend to a fixed length. The outer end of the telescopic column 63 is hinged to the support plate 66, which supports the ground and prevents the outer roller 2 from rotating. The bottom surface of the support plate 66 is fixed with an anti-slip pad 67 to increase the friction between the support plate 66 and the ground.

[0036] In a specific implementation, the length of the telescopic column 63 is manually adjusted so that the support plate 66 is supported on the ground. The length of the telescopic column 63 is fixed by adjusting the bolt 65 and the threaded connection of the adjusting hole 64. This ensures that the outer roller 2 will not rotate when the cable is pulled, replacing the function of manually holding and fixing the outer roller 2. It can also be fixed by retracting the telescopic column 63 without affecting the rolling characteristic of the outer roller 2.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
