Description

Technical Field

[0001] The utility model relates to the field of cable production and manufacturing, and more specifically, to a novel wrapping machine. Background Art

[0002] During the cable cabling process, a layer of wrapping tape is usually wrapped on the surface of the cable with a certain tension. The wrapping tape generally includes paper tape, polyester tape, aluminum foil, copper foil, mica tape, etc. Since the cabling machine and the central wrapping machine are linked, the pitch of the wrapping tape is much smaller than the pitch of the cable, and the wrapping reel needs to rotate at high speed to meet the requirements. Generally, normal operation is above 1000RPM, and the maximum can reach 3000RPM. The wrapping tape is generally light and thin, and it is easy to float up and cause the tape to break when the wrapping reel rotates at high speed. Once the tape breaks, the operator needs to wrap the cables that have not been wrapped after the tape is broken with the wrapping tape before restarting the machine for production. If the tape break cannot be discovered and stopped in time, it will take a lot of time to deal with the cables that have not been wrapped after the tape break. It not only affects the efficiency of cabling, but also the quality of cabling.

[0003] Therefore, how to prevent the wrapping tape from breaking has become a technical problem that urgently needs to be solved in this field. Utility Model Content

[0032] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0033] According to a novel wrapping machine disclosed in the present invention, a wrapping tape 11 is spirally wound around the outer periphery of a conductor 10. Figures 1 to 3 As shown, including,

[0034] A hollow shaft 12, wherein the hollow shaft 12 has a through hole 13 extending therethrough in the axial direction, and the through hole 13 is for the wire 10 to extend through;

[0035] A mounting plate 14, wherein the mounting plate 14 has a mounting hole, and the mounting plate 14 is rotatably sleeved on the hollow shaft 12 via the mounting hole, and at least one side surface of the mounting plate 14 protrudes out from a first transmission wheel 16 sleeved on the hollow shaft 12, and the first transmission wheel 16 is driven by a first motor 17 to drive the mounting plate 14 to rotate;

[0036] at least one wrapping rod 18, the wrapping rod 18 is arranged at an angle on the mounting plate 14, the wrapping rod 18 has a rotatable roller 19;

[0037] The tape reel 20 is configured to roll the wrapping tape 11 around an assembly shaft 21, and the tape reel 20 is rotatably mounted on the hollow shaft 12 via the assembly shaft 21. The wrapping tape 11 is pulled away from the tape reel 20 and then changed direction by the roller 19 and then wound around the outer periphery of the conductor 10.

[0038] The wrapping rod 18 has a rotatable roller 19. When the wrapping tape 11 rotates through the mounting plate 14 and leaves the wrapping reel 20 to be wrapped around the outer periphery of the conductor 10, the roller 19 rotates as the wrapping tape 11 leaves, thereby reducing the friction between the two, preventing the wrapping tape 11 from breaking, and improving the cable production efficiency and product quality.

[0039] In a specific implementation, the mounting plate 14 can be mounted on the hollow shaft 12 via a first bearing.

[0040] According to an embodiment of a novel wrapping machine disclosed in the present invention, the wrapping rod 18 is detachably disposed on the mounting plate 14. The wrapping rod 18 is detachably disposed relative to the mounting plate 14, and a corresponding wrapping rod 18 can be selected according to the specifications of the wrapping tape 11, thereby reducing the friction between the wrapping rod 18 and the wrapping tape 11.

[0041] According to one embodiment of a new type of wrapping machine disclosed in the present invention, the wrapping rod 18 includes a connecting portion 22, a bending portion 23 and a rolling portion 24 which are connected in sequence, the connecting portion 22 is connected to the mounting plate 14 via a bolt structure 25, the rolling portion 24 includes a connecting shaft 26 connected to the bending portion 23, and the roller 19 is rotatably mounted on the outer periphery of the connecting shaft 26.

[0042] A bending portion 23 is provided between the connecting portion 22 and the rolling portion 24 , so that the rolling portion 24 is not perpendicular to the mounting plate 14 while ensuring that the connecting portion 22 is perpendicularly connected to the mounting plate 14 , thereby preventing the wrapping tape 11 from being separated from the wrapping rod 18 .

[0043] Specifically, the connecting shaft 26 is installed in the roller 19 through at least one bearing 27. By providing the bearing 27, the roller 19 can rotate smoothly relative to the connecting shaft 26.

[0044] More specifically, the bearings 27 are multiple in number, and the bearings 27 are spaced apart along the axial direction of the connecting shaft 26. This can make the roller 19 rotate more smoothly relative to the connecting shaft 26, and prevent the roller 19 from tilting relative to the connecting shaft 26.

[0045] According to an embodiment of a novel wrapping machine disclosed in the present invention, the vertical distance from the point on the roller 19 to the conductor 10 gradually increases along the travel direction of the conductor 10. When the wrapping tape 11 is wound around the outer periphery of the conductor 10 after changing its direction through the wrapping rod 18, the wrapping tape 11 is prevented from detaching from the wrapping rod 18.

[0046] According to an embodiment of a novel wrapping machine disclosed in the present invention, there are multiple wrapping rods 18, and the multiple wrapping rods 18 are arranged at equal intervals along the circumferential direction with the conductor 10 as the center. The wrapping tape 11 can be wound on the conductor 10 after passing through more than two wrapping rods 18, extending the distance from the wrapping tape 11 to the conductor 10 from the wrapping reel 20, and reducing the friction between the wrapping tape 11 and the wrapping rods 18.

[0047] According to an embodiment of a novel wrapping machine disclosed in the present invention, a rotating shaft 28 is sleeved between the assembly shaft 21 and the hollow shaft 12, and the rotating shaft 28 has a second transmission wheel 29, a limiting portion 30 and an external threaded portion 31 in sequence along the traveling direction of the conductor 10; the assembly shaft 21 enters the limiting portion 30 via the external threaded portion 31, and is clamped between the second transmission wheel 29 and the tightening nut 32 through a threaded connection between the tightening nut 32 and the external threaded portion 31; an anti-rotation structure is provided between the outer peripheral wall of the limiting portion 30 and the inner peripheral wall of the assembly shaft 21 to prevent the two from rotating relative to each other.

[0048] The tape reel 20 is sleeved on the rotating shaft 28 via the assembly shaft 21 and is detachably connected by tightening the nut 32. A new tape reel 20 can be replaced when the tape reel 20 is used up. The anti-rotation structure arranged between the outer circumferential wall of the limiting portion 30 and the inner circumferential wall of the assembly shaft 21 can be a limiting protrusion extending along the axial direction of the assembly shaft 21 arranged on one of the outer circumferential wall of the limiting portion 30 and the inner circumferential wall of the assembly shaft 21, and the other can be a limiting groove arranged to match the above-mentioned limiting protrusion. The anti-rotation structure can make the tape reel 20 rotate with the rotating shaft 28.

[0049] In a specific implementation, the rotating shaft 28 can be installed on the hollow shaft 12 via a second bearing.

[0050] Specifically, the first transmission wheel 16 has a first wire groove 33 and a second wire groove 34, and the first wire groove 33 is connected to the output shaft of the first motor 17 through a first synchronous belt 35; the wrapping machine also includes a magnetic powder clutch, the magnetic powder clutch includes a clutch input shaft 37 and a clutch output shaft 38 rotating at different speeds relative to each other, and a magnetic powder device 39 connected between the clutch input shaft 37 and the clutch output shaft 38, the clutch input shaft 37 is connected to the second wire groove 34 via a second synchronous belt 36, and the clutch output shaft 38 is connected to the second transmission wheel 29 through a third synchronous belt 40 to apply resistance to the rotation of the second transmission wheel 29;

[0051] The magnetic powder clutch is connected to a PLC controller, which controls the connection force between the clutch output shaft 38 and the clutch input shaft 37 according to the tension value when the wrapping tape 11 is pulled away from the wrapping disk 20, so as to keep the speed at which the wrapping tape 11 is pulled away from the wrapping disk 20 unchanged.

[0052] The first motor 17 is connected to the first wire groove 33 through the first synchronous belt 35 to drive the mounting plate 14 to rotate, thereby driving the wrapping rod 18 to rotate around the hollow shaft 12, so that the wrapping tape 11 leaves the wrapping reel 20 and is wound around the outer periphery of the conductor 10; the second wire groove 34 is connected to the clutch input shaft 37 via the second synchronous belt 36, so that the clutch input shaft 37 rotates at a certain speed, and the clutch output shaft 38 is connected to the second transmission wheel 29 through the third synchronous belt 40. As the wrapping tape 11 pulls the wrapping reel 20 to rotate, as shown in FIG. As the fruit wrapping reel 20 has no resistance device, the wrapping reel 20 rotates rapidly driven by the wrapping tape 11. The wrapping tape 11 that leaves the wrapping reel 20 does not have time to rotate through the mounting plate 14 and is wound around the outer periphery of the conductor 10 and becomes tangled. To prevent the wrapping tape 11 from becoming tangled, the clutch output shaft 38 is connected to the second transmission wheel 29 via the third synchronous belt 40. A resistance is applied to the wrapping reel 20 via the clutch output shaft 38, so that the rotation of the wrapping reel 20 is synchronized with the withdrawal of the wrapping tape 11, thereby avoiding tangling of the wrapping tape 11.

[0053] The magnetic powder clutch is connected to the PLC controller, which controls the connection force between the clutch output shaft 38 and the clutch input shaft 37 according to the tension value when the wrapping tape 11 is pulled away from the wrapping disk 20, thereby changing the resistance applied by the clutch output shaft 38 to the wrapping disk 20 so that the speed at which the wrapping tape 11 is pulled away from the wrapping disk 20 remains unchanged.

[0054] In a specific implementation, the magnetic powder clutch can be fixed to the hollow shaft 12 via the connecting component 41 .

[0055] During specific implementation, the first wire groove 33 and the second wire groove 34 may be located on the same side of the mounting plate 14 , or may be disposed on both sides of the mounting plate 14 .

[0056] According to an embodiment of a novel wrapping machine disclosed in the present invention, the second transmission wheel 29 is constructed as a gear structure, and the gear structure is transmission-connected to a variable speed damper having a deceleration function. The variable speed damper applies resistance to the second transmission wheel 29 to prevent the tape reel 20 from rotating rapidly under the drive of the wrapping tape 11, and to prevent the wrapping tape 11 leaving the tape reel 20 from being wound around the outer periphery of the conductor 10 and becoming chaotic due to not having enough time to rotate through the mounting plate 14.

[0057] Although some specific embodiments of the present invention have been described in detail by way of examples, it should be understood by those skilled in the art that the above examples are for illustration only and are not intended to limit the scope of the present invention. It should be understood by those skilled in the art that the above embodiments may be modified without departing from the scope and spirit of the present invention.
