Technical Field

[0001] The utility model relates to the technical field of copper wire twisting, in particular to a multi-strand copper wire twisting device. Background Art

[0002] Copper wire is a commonly used conductive material in electrical engineering. It has good conductivity and mechanical strength and is widely used in the electrical and electronic fields. In the production process, copper wire usually uses a twisting device to twist multiple copper wires into one strand to make it more flexible and bendable.

[0003] The Chinese patent "A device for twisting enameled copper wires", with the authorization announcement number "CN219800557U", installs a winding reel with copper wire on a support rod, limits it with a nut at the top of the support rod, then pulls the copper wire through the wire hole opened on the winding reel, passes through the wire bundle tube, and finally fixes it on the winding reel. Turn on the twisting motor and the winding motor, and the winding reel and the disc rotate synchronously to achieve copper wire twisting.

[0004] Although the copper wire can be twisted in the above application, there are unstable factors in the process of the twisting drum driving the copper wire to rotate and the winding roller pulling the copper wire, which will cause the copper wire to shake, thereby affecting the twisting effect of the copper wire.

[0005] Therefore, a multi-strand copper wire twisting device is proposed to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide a multi-strand copper wire twisting device in order to solve the above-mentioned problem, thereby improving the problem that in the process of the twisting drum driving the copper wire to rotate and the winding roller pulling the copper wire, there are unstable factors, which may cause the copper wire to shake, thereby affecting the twisting effect of the copper wire.

[0008] Preferably, the protection mechanism also includes a first bevel gear rotatably connected to one end of the circular plate, the surface of the first bevel gear is meshingly connected with a second bevel gear distributed in an annular manner, the number of the second bevel gears is the same as the number of the second arc plates, one end of the second bevel gear is fixedly connected to a screw, the other end of the screw is fixedly connected to a fixed block, one side of the fixed block is fixedly connected to one end of the circular plate, the surface of the screw is threadedly connected to a moving ring, the surface of the moving ring is fixedly connected to a connecting rod, and the other end of the connecting rod is fixedly connected to the surface of the corresponding second arc plate. The staff drives multiple second bevel gears to rotate synchronously by rotating the first bevel gear, which is conducive to promoting the synchronous movement of multiple second arc plates and improving the consistency of the device during operation.

[0009] Preferably, the other ends of the first arc plate and the second arc plate are fixedly connected to a guide plate, and the other ends of the guide plate are fixedly connected to a brush. When the copper wire is pulled and moved during the twisting process, the brush is used to clean the surface of the copper wire, thereby improving the twisting effect of the copper wire, and under the action of the inclined surface of the guide plate, the cleaned impurities are better dropped.

[0010] Preferably, the first curved plate and the second curved plate are both in the shape of a half circular ring, and the diameter of the first curved plate is the same as the diameter of the second curved plate.

[0011] Preferably, the surface of the guide plate is provided with through holes, which is conducive to better dropping of impurities that fall on the inner side of the guide plate during cleaning.

[0012] Preferably, both ends of the first arc plate are fixedly connected with a clamping block, and both ends of the second arc plate are provided with a clamping groove, which is conducive to better forming the first arc plate and the corresponding second arc plate into a whole.

[0025] When implementing: Figure 1-5 As shown, a multi-strand copper wire twisting device comprises: a base 1, a fixing plate 2, a mounting frame 4, a wire bundle tube 6 and a fixing frame 7 are fixedly connected in sequence from one side of the top of the base 1 to the other side of the top, a mounting plate 3 is rotatably connected to one side of the fixing plate 2, a circular plate 5 is rotatably connected to the inner wall of the mounting frame 4, a surface of the circular plate 5 is provided with lead holes 51 distributed in an annular shape, a winding roller 8 is rotatably connected to the inner wall of the fixing frame 7, and a protective mechanism 9 is arranged at one end of the circular plate 5; wherein the protective mechanism 9 comprises a plurality of first arc plates 91 fixedly connected to one end of the circular plate 5, a second arc plate 92 distributed in an annular shape is slidably connected to one end of the circular plate 5, the number of the first arc plates 91 and the second arc plates 92 arranged is the same as the number of the lead holes 51, and the positions of the first arc plates 91 and the second arc plates 92 correspond one to one to the positions of the lead holes 51.

[0026] The structure of the mounting plate 3 is the same as that in the original scheme. A gear ring is fixedly connected to the surface of the circular plate 5. A first motor is fixedly connected to the top of the base 1. A gear is fixedly connected to the output shaft of the first motor. The gear is meshed with the gear ring. When the circular plate 5 needs to be rotated, the first motor can be started by the controller to drive the gear to rotate and thereby drive the gear ring to rotate. A U-shaped rod is fixedly connected to one end of the circular plate 5. A fixed rod is fixedly connected to the surface of the U-shaped rod. The other end of the fixed rod is fixedly connected to one end of the mounting plate 3. A second motor is fixedly connected to one side of the fixing frame 7. The output shaft of the second motor is fixedly connected to one end of the winding roller 8. Starting the second motor by the controller can drive the winding roller 8 to rotate.

[0027] When twisting multiple strands of copper wires, the winding reel wound with copper wires is installed on the mounting plate 3, and the multiple copper wires are pulled through the lead holes 51 respectively, and then the multiple copper wires are passed through the bundle tube 6 together and fixed on the winding roller 8. After completing this operation, the circular plate 5 is driven to rotate, and the rotation of the circular plate 5 drives the mounting plate 3 to rotate synchronously. When the winding roller 8 is driven to rotate, the twisting operation of multiple copper wires can be realized.

[0028] like Figure 3 and Figure 4 As shown, the protective mechanism 9 also includes a first bevel gear 93 rotatably connected to one end of the circular plate 5, the surface of the first bevel gear 93 is meshingly connected with a ring-distributed second bevel gear 94, the number of second bevel gears 94 is the same as the number of second arc plates 92, one end of the second bevel gear 94 is fixedly connected to a screw rod 95, the other end of the screw rod 95 is fixedly connected to a fixed block 96, one side of the fixed block 96 is fixedly connected to one end of the circular plate 5, the surface of the screw rod 95 is threadedly connected to a moving ring 97, the surface of the moving ring 97 is fixedly connected to a connecting rod 98, and the other end of the connecting rod 98 is fixedly connected to the surface of the corresponding second arc plate 92.

[0029] The position and number of the second arc plate 92 and the first arc plate 91 correspond one to one. When the device is in the initial state, when the copper wire is passed through the lead hole 51, the second arc plate 92 is away from the corresponding first arc plate 91. When the staff fixes the copper wire on the winding roller 8, the staff can rotate the first bevel gear 93 to drive multiple first bevel gears 93 to rotate synchronously, thereby driving the corresponding screw rod 95 to rotate. When the screw rod 95 rotates, it will drive the moving ring 97 and the connecting rod 98 to move synchronously, so that the connecting rod 98 pushes the corresponding second arc plate 92 to move, so that the two ends of the second arc plate 92 are in contact with the two ends of the corresponding first arc plate 91. At this time, the first arc plate 91 and the second arc plate 92 form a circular tube, and the copper wire is located on the inner side of the circular tube.

[0030] like Figure 3 and Figure 4 As shown, the other ends of the first curved plate 91 and the second curved plate 92 are fixedly connected to a guide plate 99, and the other end of the guide plate 99 is fixedly connected to a brush 910. A through hole 913 is provided on the surface of the guide plate 99. When the second curved plate 92 and the corresponding first curved plate 91 form a circular tube, the two guide plates 99 will form a guide tube with a trumpet-shaped opening, and the two brushes 910 are attached to form a ring brush, and the bristles of the brush 910 are attached to the copper wire. When the copper wire is pulled and moved during the twisting process, the brush 910 will clean the surface of the copper wire at the same time, and the cleaned impurities will fall through the through hole 913 and the inclined surface of the guide plate 99.

[0031] like Figure 2 , Figure 3 and Figure 4 As shown, the first curved plate 91 and the second curved plate 92 are both in the shape of a half circular ring, and the diameter of the first curved plate 91 is the same as the diameter of the second curved plate 92. The inner wall diameter of the circular tube formed by the second curved plate 92 and the corresponding first curved plate 91 is the same as the inner wall diameter of the lead-in hole 51, and the center of the formed circular tube is on the same horizontal plane as the center of the corresponding lead-in hole 51.

[0032] like Figure 5 As shown, both ends of the first curved plate 91 are fixedly connected with a clamping block 912, and both ends of the second curved plate 92 are provided with a clamping slot 911. The other end of the clamping block 912 is bent into an arc shape. When the two ends of the second curved plate 92 are fitted with the two ends of the corresponding first curved plate 91, the clamping block 912 will enter the clamping slot 911, and the upper end of the inner wall of the clamping slot 911 is bent into an arc shape.

[0033] like Figure 4 As shown, the other end of the first bevel gear 93 passes through the circular plate 5 and is fixedly connected with a knob 914. When the first bevel gear 93 needs to be rotated, the staff rotates the knob 914 to drive the first bevel gear 93 to rotate, and the surface of the knob 914 is provided with protrusions distributed in an annular shape.

[0034] When the utility model is used, when twisting multiple strands of copper wires, the winding drum with the copper wire is installed on the mounting plate 3, and the multiple copper wires are pulled through the lead holes 51 respectively, and then the multiple copper wires are passed through the wire bundle tube 6 together and fixed on the winding roller 8. After completing this operation, the staff turns the knob 914 to drive the first bevel gear 93 to rotate, thereby driving the multiple second bevel gears 94 to rotate synchronously. When the second bevel gear 94 rotates, it will drive the corresponding screw rod 95 to rotate and make the moving ring 97 and the connecting rod 98 move synchronously, so that the connecting rod 98 pushes the corresponding second arc plate 92 to move, so that the two ends of the second arc plate 92 fit with the two ends of the corresponding first arc plate 91. The blocks 912 at both ends of the first arc plate 91 enter the slots 911 at both ends of the second arc plate 92. At this time, the first arc plate 91 and the second arc plate 92 form a circular tube, the two guide plates 99 will form a guide tube with a trumpet-shaped opening, and the two brushes 910 are fitted together to form a ring-shaped brush. The copper wire is located on the inner side of the circular tube, and the bristles of the brush 910 are fitted with the copper wire. At this time, the circular plate 5, the mounting plate 3 and the winding roller 8 are driven to rotate synchronously to twist multiple copper wires. When the copper wire is pulled and moved during the twisting process, the brush 910 will clean the surface of the copper wire at the same time, and the circular tube formed by the first arc plate 91 and the second arc plate 92 will limit the copper wire.

[0035] It should be noted that the first motor, the second motor, etc. in the above description are all devices with relatively mature application of existing technologies. The specific models can be selected according to actual needs. At the same time, the first motor and the second motor can be powered by a built-in power supply or by AC power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0036] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
