DETAILED DESCRIPTION

[0038] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0039] See also Figure 1-Figure 5 The utility model provides a technical solution: a cable constant tension tape wrapping device, comprising a bracket 1 provided with a wire feed slot 2; the wire feed slot 2 is used to pass the cable core 3, rotate a winding disc 4 provided on one side of the bracket 1 and a driving component for driving the winding disc 4 to rotate; a swing arm 11 provided on one side of the winding disc 4; a belt roller 14 provided with an end shaft 15; specifically, a first rotating ring 9 is provided on the other side of the winding disc 4 relative to the swing arm 11, and the first rotating ring 9 is rotatably matched with a first annular groove 10 provided in the bracket 1; the driving component comprises: a first motor 5 provided on one side of the bracket 1 and a gear 6 installed on the output shaft of the first motor 5; a rack 8, which is provided in a recessed groove 7 provided in the winding disc 4 to cooperate with the gear 6 for meshing transmission;

[0040] The above technical solution can be used to wrap the cable core 3. When in use, the cable core 3 passes through the cable feed slot 2, and a section of the tape on the surface of the tape roller 14 is pulled out and fixed on the surface of the cable core 3. Then, the cable core 3 is continuously fed by the traction equipment, and the first motor 5 is started to drive the gear 6 to rotate, and the gear 6 drives the rack 8 to engage, thereby driving the winding disk 4 to rotate around the bracket 1, and the winding disk 4 drives the swing arm 11 to rotate, and the swing arm 11 drives the tape roller 14 to rotate, and the tape roller 14 continuously wraps the tape on its surface around the surface of the cable core 3 to achieve wrapping.

[0041] The cable constant tension tape wrapping device comprises: a shell 21 with a receiving cavity on one side, which is installed at the lower end of the swing arm 11; a turntable 22, which is rotatably arranged in the receiving cavity, and the turntable 22 is connected to the end shaft 15; specifically, a second rotating ring 24 is arranged on one side of the turntable 22, and the second rotating ring 24 is rotatably matched with a second annular groove 25 opened in the shell 21; a roller 27, which is arranged on the outer edge surface of the turntable 22; a plurality of protrusions 29, which are distributed in an annular array about the central axis of the shell 21, and the protrusions 29 are movably arranged in an inner groove 28 opened in the shell 21; an elastic member 30, which is arranged in the inner groove 28 to push the protrusion 29 to contact the roller 27; in this embodiment, the elastic member 30 is a spring;

[0042] The above-mentioned technical solution can be used to damp and limit the speed of the belt roller 14. During the rotation of the belt roller 14, the polygonal prism 16 at the end of the belt roller 14 will cooperate with the prism groove 23 to synchronously drive the turntable 22 to rotate. The turntable 22 drives the roller 27 on its surface to continuously contact the protrusion 29. The protrusion 29 retracts into the inner groove 28 after being compressed. After the roller 27 disengages from the protrusion 29, the elastic member 30 drives the protrusion 29 to reset, thereby producing a damping effect on the rotation of the belt roller 14 and preventing the belt roller 14 from automatically rotating due to inertia.

[0043] Further, such as Figure 5 As shown, the cable constant tension tape wrapping device further includes an electric push rod 26, the bottom of which is arranged in an opening formed in the rotating disk 22, and the output end of the electric push rod 26 is connected to the roller 27;

[0044] The above technical solution can adjust the damping effect. When the damping strength needs to be adjusted, the electric push rod 26 can be controlled to drive the roller 27 to extend and retract, thereby adjusting the distance between the roller 27 and the protrusion 29. The smaller the distance, the greater the damping strength, and vice versa.

[0045] Further, such as Figure 4 and Figure 5 As shown, a polygonal column 16 is disposed at one end of the end shaft 15, and the polygonal column 16 is engaged with a prism groove 23 provided on the rotating disk 22;

[0046] The above technical solution can be used to facilitate the disassembly of the belt roller 14 , and the polygonal column 16 of the end shaft 15 on the other side of the belt roller 14 can be pulled out from the prism groove 23 of the turntable 22 , thereby completing the disassembly of the belt roller 14 .

[0047] Furthermore, if Figure 4 As shown, the cable constant tension tape wrapping device also includes a clamping plate 12, which is located at the lower end of the swing arm 11 and on one side relative to the housing 21, and a rotating groove 13 for inserting the end shaft 15 is provided on the surface of the clamping plate 12; a slider 18, which is provided at the upper end of the clamping plate 12, and the slider 18 is slidably matched with a slide groove 17 provided at the bottom of the swing arm 11; a pushing component, which is used to drive the slider 18 to slide in the slide groove 17; in this embodiment, the pushing component includes: a second motor 19, which is provided at one end of the swing arm 11, and the output shaft of the second motor 19 passes through one end of the swing arm 11 and extends into the slide groove 17; a screw rod 20, which is connected to the output shaft of the second motor 19, and the screw rod 20 is matched with the screw rod groove provided in the slider 18;

[0048] The above technical solution can be used to stably limit the belt roller 14 to prevent it from falling. When the belt roller 14 needs to be replaced, the second motor 19 is started to drive the screw rod 20 to rotate, thereby driving the slider 18 to slide along the slide groove 17, so that the splint 12 slides synchronously until the rotating groove 13 of the splint 12 is disconnected from the end shaft 15 of the belt roller 14, which is more convenient.

[0049] Working principle: When in use, the cable core 3 passes through the cable inlet groove 2, and a section of the tape on the surface of the tape roller 14 is pulled out and fixed on the surface of the cable core 3, and then the cable core 3 is continuously fed by the traction device, and the first motor 5 is started to drive the gear 6 to rotate, and the gear 6 drives the rack 8 to engage, thereby driving the winding disk 4 to rotate around the bracket 1, and the winding disk 4 drives the swing arm 11 to rotate, and the swing arm 11 drives the tape roller 14 to rotate, and the tape roller 14 continuously wraps the tape on its surface around the surface of the cable core 3 to achieve wrapping;

[0050] During the rotation of the belt roller 14, the multi-prism 16 at the end of the belt roller 14 will cooperate with the prism groove 23 to synchronously drive the turntable 22 to rotate, and the turntable 22 drives the roller 27 on its surface to continuously contact the protrusion 29. The protrusion 29 retracts into the inner groove 28 after being pressed, and after the roller 27 is separated from the protrusion 29, the elastic member 30 drives the protrusion 29 to reset, thereby generating a damping effect on the rotation of the belt roller 14 to prevent the belt roller 14 from automatically rotating due to inertia. When the damping strength needs to be adjusted, the roller 27 can be driven to retract by controlling the electric push rod 26, thereby adjusting the distance between the roller 27 and the protrusion 29. The smaller the distance, the greater the damping strength, and vice versa.

[0051] When the belt roller 14 needs to be replaced, the second motor 19 is started to drive the screw 20 to rotate, thereby driving the slider 18 to slide along the slide groove 17, so that the splint 12 slides synchronously until the rotating groove 13 of the splint 12 is disconnected from the end shaft 15 of the belt roller 14, and the polygonal prism 16 of the end shaft 15 on the other side of the belt roller 14 can be pulled out of the prism groove 23 of the turntable 22, thereby completing the disassembly of the belt roller 14.
