Description

Technical Field

[0001] The invention relates to the technical field of cable wrapping machines, in particular to a cable wrapping machine for a wire harness production line. Background Art

[0002] The cable wrapping machine for wire harness production line is a device used for wrapping the insulated core wires of electric wires, power cables, control cables, optical cables, etc. The cable wrapping machine, also known as a paper wrapping machine, is a device that wraps the tape (such as mica tape, cotton paper tape, aluminum foil, polyester film, etc.) around the core wire by rotating the turntable. It is mainly used for electric wires, power cables, and control cables.

[0003] However, the existing cable wrapping machines for existing harness production lines have problems and shortcomings during use. These problems may affect production efficiency, product quality and operator safety. Loose winding during the movement of the wrapped cable will cause the cable to shake. A small shake of the cable may have a series of adverse effects on the wrapping quality. A small shake of the cable may cause uneven wrapping layers. When the cable shakes during the wrapping process, its position will change slightly, which may cause inconsistent wrapping thickness of each layer. This unevenness not only affects the appearance of the cable, but also its electrical and mechanical properties. Shaking may also cause the cables to be arranged unevenly during the wrapping process. The ideal wrapping state is that the cables are arranged tightly and neatly together to form a uniform wrapping layer. Summary of the invention

A limiting mechanism 800 is provided for supporting the cable, a winding mechanism 900 for wrapping the cable is provided at the upper end of the base 100, a second support block 1000 is fixedly connected to the upper end of the base 100, an outer ring of a second bearing 1100 is fixedly connected to the upper end of the second support block 1000, a second disc 1200 is fixedly connected to the inner ring of the second bearing 1100, and a fitting mechanism 1300 for fitting three round rods 600 to the surface of the cable is provided inside the second disc 1200.

[0018] Preferably, a slide groove 6001 is provided inside the round rod 600, and the slide groove 6001 is slidably connected to the first sliding block 601 and elastically connected through a spring, and the lower end of the first sliding block 601 is fixedly connected to an arc plate 602; the cable passes through the center of the sleeve 905, and the cable is led out from the unwinder through the circular hole in the center of the second disc 1200 and the third disc 1304, and the cable passes through the circular hole in the center of the first disc 400 and the first bearing 300 at the other end of the winding machine and is wound to the winding machine, and the cable is wound at a uniform speed by the winding machine. When the cable is being wound up, it moves along its own length and does not rotate. The hydraulic cylinder 1301 is started to move toward the center of the third disk 1304. The movement of the hydraulic cylinder 1301 drives the second sliding block 1302 to move. The movement of the second sliding block 1302 drives the sliding rod 1303 to move. The sliding rod 1303 moves toward the center of the third disk 1304 and slides in the third hollow groove 1305, thereby driving the third disk 1304 to rotate. The rotation of the third disk 1304 drives the other two sliding rods 1303 to move toward the third disk 1304. The sliding rod 1303 moves downward, which drives the round rod 600 to move toward the center of the third disk 1304. The three round rods 600 move toward the center of the third disk 1304 to wrap the cable. When the three round rods 600 rotate around the cable, they also drive the first sliding block 601 to rotate. The rotation of the first sliding block 601 drives the arc plate 602 to rotate. The first sliding block 601 is elastically connected to the round rod 600 through a spring, so the arc plate 602 is tightly attached to the surface of the cable and has a certain elasticity to avoid pressure on the cable. The force is too great so that the cable cannot move, or the pressure applied by the round rod 600 to the cable is too small, resulting in loose wrapping. The arc plate 602 arranged on the surface of the round rod 600 can buffer the pressure between the round rod 600 and the cable and the winding material, so that the arc plate 602 can keep the pressure applied to the cable constant, so that the cable can be wrapped with mica tape evenly. At the same time, the three round rods 600 and the arc plates 602 on their surfaces can also smooth and tighten the material wrapped on the cable surface, so that the cables are tightly and neatly arranged together.

[0019] Preferably, the cleaning mechanism 700 includes a fixed block 701, one end of which is fixedly connected to the surface of the round rod 600, and a brush 702 is provided on the surface of the fixed block 701; when the round rod 600 moves toward the center of the third disk 1304, the fixed block 701 is driven to move, and the movement of the fixed block 701 drives the brush 702 to move toward the center of the third disk 1304, and when the three round rods 600 rotate around the cable, the fixed block 701 and the brush 702 on their surfaces are driven to rotate, and the rotation of the brush 702 cleans the dust and impurities on the surface of the cable, thereby preventing the dust and impurities from affecting the subsequent winding on the cable surface; the structure is set up so that the three round rods 600 rotate around the cable and the brush 702 is driven to rotate, and the rotation of the brush 702 cleans the dust and impurities on the surface of the cable, and the cable led out from the unwinding machine is pre-treated by the brush 702, and the dust and impurities on the cable surface are removed, thereby preventing the dust and impurities from affecting the subsequent winding on the cable surface.

[0020] Preferably, the limiting mechanism 800 includes a rotating shaft 801, both ends of which are rotatably connected to the first connecting block 500, and a pressure wheel 802 is rotatably connected to the surface of the rotating shaft 801; the three round rods 600 move toward the center of the third disk 1304 and drive the first connecting block 500 to move downward, the downward movement of the first connecting block 500 drives the rotating shaft 801 to move downward, the downward movement of the rotating shaft 801 drives the pressure wheel 802 to move downward, and the three pressure wheels 802 move toward the center of the cable to clamp the cable in the middle; the cable is wrapped in the middle by the three round rods 600. The center can prevent the cable from shaking during the wrapping process, so that the cables are arranged tightly and neatly to form a uniform wrapping layer. The three round rods 600 are used to wrap the cables in the center, and cables of different thicknesses can be wrapped. The clamping of cables of different thicknesses can be adjusted. The three round rods 600 will wrap the cables in the center and drive the three pressure wheels 802 to fit the surface of the cables. The three pressure wheels 802 fit on the surface of the cables to play a limiting role. The three pressure wheels 802 fit on the surface of the cables to avoid the rotation and shaking of the cables during winding.

[0021] Preferably, the winding mechanism 900 includes a servo motor 901, which is mounted on the upper end of the base 100. The output end of the servo motor 901 is fixedly connected to a first transmission wheel 902, a belt 903 is meshed on the surface of the first transmission wheel 902, one end of the belt 903 is meshed with a second transmission wheel 904, and a sleeve 905 is fixedly connected to the inner surface of the second transmission wheel 904; at this time, the servo motor 901 is started to rotate at a uniform speed, the rotation of the servo motor 901 will drive the first transmission wheel 902 to rotate, the rotation of the first transmission wheel 902 will drive the belt 903 to rotate, and the rotation of the belt 903 will drive the second transmission wheel 9 04 rotates, the rotation of the second transmission wheel 904 will drive the sleeve 905 to rotate, the rotation of the sleeve 905 will drive the second disc 1200 to rotate, the rotation of the second disc 1200 will drive the second sliding block 1302 to rotate, the rotation of the second sliding block 1302 will drive the sliding rod 1303 to rotate, the rotation of the sliding rod 1303 will drive the round rod 600 to rotate, and when the second disc 1200 rotates, it will drive the second connecting block 1201 to rotate around the cable, the rotation of the second connecting block 1201 will drive the bracket 1202 to rotate, the rotation of the bracket 1202 will drive the roller 1203 to rotate, and the rotation of the roller 1203 will drive the mica tape 1204 to rotate around the cable.

[0022] Preferably, a second connecting block 1201 is fixedly connected to the surface of the second disk 1200, a bracket 1202 is fixedly connected to the upper end of the second connecting block 1201, a roller 1203 is rotatably connected inside the bracket 1202, a mica tape 1204 is wound around the surface of the roller 1203, and a second hollow groove 1205 is opened inside the second disk 1200.

[0023] Preferably, the bonding mechanism 1300 includes a hydraulic cylinder 1301, a non-output end of the hydraulic cylinder 1301 is fixedly connected to the second disc 1200, an output end of the hydraulic cylinder 1301 is fixedly connected to a second sliding block 1302, one end of the second sliding block 1302 is fixedly connected to a sliding rod 1303, a third disc 1304 is bonded to the surface of the second disc 1200, and a third hollow groove 1305 is opened inside the third disc 1304.

[0024] Working principle: When the present invention is used, the cable passes through the center of the sleeve 905, the cable is led out from the unwinder through the circular holes in the center of the second disc 1200 and the third disc 1304, the cable passes through the circular holes in the center of the first disc 400 and the first bearing 300 at the other end of the winding machine, and is wound to the winding machine. The winding machine winds the cable at a uniform speed. During the process of the cable being wound, it moves along its own length direction and does not rotate. The hydraulic cylinder 1301 is started to move toward the center of the third disc 1304, and the movement of the hydraulic cylinder 1301 drives the second The sliding block 1302 moves, and the movement of the second sliding block 1302 will drive the sliding rod 1303 to move. The sliding rod 1303 moves toward the center of the third disk 1304 and slides in the third hollow groove 1305, thereby driving the third disk 1304 to rotate. The rotation of the third disk 1304 will drive the other two sliding rods 1303 to move toward the center of the third disk 1304. The downward movement of the sliding rod 1303 will drive the round rod 600 to move toward the center of the third disk 1304. The three round rods 600 move toward the center of the third disk 1304 to wrap the cable.

[0025] When the round rod 600 moves toward the center of the third disk 1304 , it drives the fixed block 701 to move, and the movement of the fixed block 701 drives the brush 702 to move toward the center of the third disk 1304 .

[0026] The three round rods 600 move toward the center of the third disk 1304 while also driving the first connecting block 500 to move downward. The downward movement of the first connecting block 500 drives the rotating shaft 801 to move downward. The downward movement of the rotating shaft 801 drives the pressing wheel 802 to move downward. The three pressing wheels 802 move toward the center of the cable to clamp the cable in the middle. By setting the three round rods 600 to wrap the cable in the center, the influence caused by the shaking of the cable during the wrapping process can be prevented, and the cables can be arranged tightly and neatly together to form a uniform wrapping layer. The three round rods 600 are used to wrap the cable in the center, and the wrapping of cables of different thicknesses can be handled. The clamping of cables of different thicknesses can be adjusted. The three round rods 600 wrap the cable in the center while driving the three pressing wheels 802 to fit against the surface of the cable. The three pressing wheels 802 fit against the surface of the cable to play a limiting role. The three pressing wheels 802 fit against the surface of the cable to prevent the rotation and shaking of the cable during winding.

[0027] At this time, the servo motor 901 is started to rotate at a uniform speed. The rotation of the servo motor 901 will drive the first transmission wheel 902 to rotate, the rotation of the first transmission wheel 902 will drive the belt 903 to rotate, the rotation of the belt 903 will drive the second transmission wheel 904 to rotate, the rotation of the second transmission wheel 904 will drive the sleeve 905 to rotate, the rotation of the sleeve 905 will drive the second disc 1200 to rotate, the rotation of the second disc 1200 will drive the second sliding block 1302 to rotate, the rotation of the second sliding block 1302 will drive the sliding rod 1303 to rotate, the rotation of the sliding rod 1303 will drive the round rod 600 to rotate, and when the second disc 1200 rotates, the second connecting block 1201 will drive the bracket 1202 to rotate, the rotation of the bracket 1202 will drive the roller 1203 to rotate, and the rotation of the roller 1203 will drive the mica tape 1204 to rotate around the cable.

[0028] When the three round rods 600 rotate around the cable, the fixed block 701 and the brush 702 on the surface thereof will be driven to rotate. The rotation of the brush 702 will clean the dust and impurities on the cable surface, thus preventing the dust and impurities from affecting the subsequent winding on the cable surface. The structure is set so that the three round rods 600 rotate around the cable and the brush 702 will be driven to rotate. The rotation of the brush 702 will clean the dust and impurities on the cable surface. The cable led out from the unwinding machine is pre-processed by the brush 702, so that the dust and impurities on the cable surface are removed, thus preventing the dust and impurities from affecting the subsequent winding on the cable surface.

[0029] When the three round rods 600 rotate around the cable, they will also drive the first sliding block 601 to rotate. The rotation of the first sliding block 601 will drive the arc plate 602 to rotate. The first sliding block 601 is elastically connected to the round rod 600 through a spring, so the arc plate 602 is tightly fitted on the surface of the cable and has a certain elasticity, so as to avoid excessive pressure on the cable that makes the cable unable to move, or too little pressure on the cable that makes the wrapping loose. The arc plate 602 arranged on the surface of the round rod 600 can buffer the pressure between the round rod 600 and the cable and the winding material, so that the arc plate 602 can make the pressure applied to the cable constant, so that the cable can be wrapped with mica tape evenly. At the same time, the three round rods 600 and the arc plate 602 on their surface can also smooth and tighten the material wrapped on the cable surface, so that the cables are arranged tightly and neatly together.
