Description

Technical Field

[0001] The utility model belongs to the technical field of cable winding, and in particular relates to a tension regulating structure for cable winding. Background Art

[0002] Cable refers to the conductor for transmitting electric energy, which is divided into bare wire, electromagnetic wire and insulated wire. Bare wire has no insulation layer, including copper, aluminum flat wire, overhead stranded wire and various profiles (such as profiled wire, busbar, copper busbar, aluminum busbar, etc.). After the existing cables are processed, in order to facilitate the storage and transportation of the cables, it is often necessary to put a reel frame for storing the cables outside the reel and fix the reel frame. The reel roller drives the reel frame to rotate during the rotation process, so that the cable is wound on the reel frame.

[0003] For example, a Chinese utility model patent with announcement number CN218024642U discloses a cable winding tension adjustment structure, in which a motor is provided to drive a winding drum frame to rotate, and the cable is wound by the winding drum frame. The electric push rod is extended and retracted to drive the slider to move left and right along the strip opening, and the slider drives the support block and the cable to move, thereby causing the cable to be spirally wound on the winding drum frame.

[0004] The device adjusts the tension by changing the distance between the upper pressure roller and the lower pressure roller. However, when the cable is reeled in, the surface of the cable is affected by the friction between the upper pressure roller and the lower pressure roller, which can easily cause cable wear and affect the service life of the cable.

[0005] In summary, there is currently a need for a cable winding device that can adjust the tension while avoiding friction on the cable. Utility Model Content

[0031] The auxiliary winding component includes a first reciprocating screw rod 18 installed in a linear guide groove opened at the top of the support frame 3, the outer side of the first reciprocating screw rod 18 is threadedly connected to a moving block, and the bottom of the moving block is fixedly connected to an adjusting component 19, the adjusting component 19 includes a displacement plate, the bottom of the displacement plate is provided with a linear guide groove, a bidirectional screw rod is installed in the linear guide groove, the surface of the bidirectional screw rod is threadedly connected to the displacement block, the bottoms of the two displacement blocks are respectively fixedly connected with a C-shaped storage plate and a C-shaped insertion plate, which is convenient for adapting to cables of different sizes, the left side of the adjusting component 19 is fixedly connected with a cleaning frame 20 through a connecting plate, the top and bottom of the inner wall of the cleaning frame 20 are fixedly connected with a brush plate 21, the brush plate 21 includes a prism plate, and bristles are fixedly connected to one side of the prism plate at equal intervals, and the prism plate facilitates the dust brushed off to fall onto the bottom plate 1 along the inclined surface of the prism plate.

[0034] The implementation principle of a cable winding tension adjustment structure in an embodiment of the present application is: before the device works, the bidirectional screw is rotated according to the size of the cable, so that the two displacement blocks drive the C-shaped storage plate and the C-shaped insertion plate to approach each other, so that the adjustment component 19 adapts to the size of the cable and improves the applicability of the device.

[0035] After the adjustment of the adjusting component 19 is completed, the screw rod 9 is rotated so that the screw rod 9 drives the upper pressure roller 10 to move downward through the connecting frame 7, so that the distance between the upper pressure roller 10 and the lower pressure roller 8 is changed, thereby completing the tension adjustment. In the process of the upper pressure roller 10 descending, the connecting frame 7 drives the first bevel gear 11 to move downward.

When the cable is wound, the second motor 16 is started, so that the upper pressure roller 10 and the lower pressure roller 8 are relatively rotated under the action of the first bevel gear 11, the second bevel gear 13, the third bevel gear 17 and the fourth bevel gear 14, so that when the cable is wound, the friction between the cable and the tension adjustment roller can be reduced, the wear degree of the cable is reduced, and the service life of the cable is extended.

[0036] During the cable winding process, the first motor 6 drives the first reciprocating screw 18 to rotate through the first synchronous belt, so that the moving block drives the adjusting component 19 and the cleaning frame 20 to perform repeated back and forth movements, thereby assisting the cable to be evenly wound on the winding roller 5 during the winding process. The brush plate 21 in the cleaning frame 20 cleans the impurities attached to the surface of the cable, and the brushed impurities fall to the top of the bottom plate 1 along the brush plate 21. At the same time, the intermediate shaft of the lower pressure roller 8 drives the second reciprocating screw 22 to rotate through the second synchronous belt, so that the cleaning plate 24 moves back and forth along the second reciprocating screw 22, pushing the impurities on the top of the bottom plate 1 into the winding box, reducing the wear of the impurities on the cable sheath, thereby improving the service life of the cable.
