Description

Technical Field

[0001] This invention relates to a cable wrapping machine, and more particularly to a dual-axis supported power wrapping machine. Background Technology

[0002] The existing wrapping machines generally use a shaft-through-shaft structure for the tape feeding reel. Both the tape feeding reel and the rotating support are supported by a single-sided bearing seat, with the other side unsupported and suspended. Therefore, when the tape feeding reel rotates to feed the tape, it is only subjected to the torque force at one end of the tape feeding shaft, and the rotating support is only subjected to the torque force at one end of the main shaft when rotating. This results in uneven force distribution at both ends of the tape feeding reel and the rotating support, which generates significant vibration at high speeds, leading to loud operating noise, unstable operation, and ultimately reduced production efficiency.

[0003] In addition, the existing wrapping machine has a large distance between the wrapping tape and the position where it is wrapped with the core wire after being pulled out. The large distance increases the wind resistance, resulting in loud working noise and unstable rotation. Furthermore, the wind resistance during high-speed or low-speed rotation causes inconsistent tension, which can easily lead to unstable product quality after wrapping. Summary of the Invention

[0004] The purpose of this invention is to provide a dual-axis supported power wrapping machine, which is supported on both sides of the tape feeding reel and the rotating bracket by dual axes, so that the tape feeding reel and the rotating bracket operate more smoothly, with less vibration and noise, and effectively improves production efficiency.

[0005] To achieve the above objectives, the present invention provides a dual-axis supported power wrapping machine comprising a tape feeding mechanism, a traction mechanism, and a central rod. The tape feeding mechanism includes a main shaft, a tape feeding shaft, a rotating bracket, a tape feeding reel, a bracket drive mechanism, and a tape reel drive mechanism. The main shaft is coaxially and rotatably sleeved around the tape feeding shaft. The center of one side of the tape feeding reel is connected to one end of the tape feeding shaft, and the center of the other side of the tape feeding reel is coaxially and rotatably connected to the rotating shaft of the traction mechanism. The center of one side of the rotating bracket is fixedly connected to one end of the main shaft, and the center of the other side of the rotating bracket is coaxially and fixedly connected to the rotating shaft. The tape feeding shaft has a first through hole penetrating both ends, and the rotating shaft has a second through hole penetrating both ends. The central rod passes through the first through hole and the second through hole to allow the core wire to be conveyed forward from within the central rod. The tape reel drive mechanism drives the tape feeding shaft to rotate, thereby driving the tape feeding reel to release the wrapping tape. The bracket drive mechanism drives the main shaft to rotate, thereby causing the traction mechanism to rotate and wrap the tape around the core wire.

[0006] Compared with the prior art, this invention connects the center of the other side of the tape unloading reel to the rotating shaft of the traction mechanism in a coaxial and rotatable manner, and the center of the other side of the rotating bracket is fixedly connected to the rotating shaft of the traction mechanism in a coaxial manner. This allows the rotating shaft of the traction mechanism to rotate with the rotating bracket, and provides a support point on the other side of the rotating bracket. The rotating shaft of the traction mechanism can also provide a support point on the other side of the tape unloading reel. Therefore, the forces on both ends of the rotating bracket and the tape unloading reel are balanced, resulting in smoother operation and enabling high-speed operation. Compared with a single-sided support structure, this invention effectively improves production efficiency, greatly reduces vibration and noise, and reduces wear on components, heat generation, and failure rate, effectively extending service life.

[0007] Preferably, a connecting member is provided between the tape feeding reel and the rotating shaft, one end of the connecting member is connected to the center of the tape feeding reel, and the other end of the connecting member is rotatably connected to the rotating shaft through a bearing.

[0008] Preferably, the tape feeding mechanism further includes a braking device that stops the main shaft from rotating.

[0009] Preferably, the side wall of the rotating bracket near the traction mechanism is eccentrically provided with a pass-through hole, so that the strap, after being released from the tape reel, passes through the pass-through hole and extends into the traction mechanism.

[0010] Preferably, the traction mechanism includes the rotating shaft, a turntable, a traction assembly, and a first drive mechanism. The rotating shaft is rotatably arranged. The traction assembly includes a first steering wheel and a pressure roller assembly pivotally connected to one side of the turntable in a centrally symmetrical manner. The turntable is coaxially fixed to one end of the rotating shaft. The first steering wheel is disposed on the turntable to cause the strap to turn. The first drive mechanism drives the pressure roller assembly to rotate so that the pressure roller assembly tractions the strap. By setting two pressure roller groups on the turntable in a symmetrical manner, and by setting a first steering wheel on the turntable, the two pressure roller groups and the first steering wheel are basically on the same radial plane. When the wrapping tape wraps around the two pressure roller groups and the first steering wheel to cover the core wire, the axial distance from the wrapping tape leading out of the rotating shaft to the core wire is very short. Therefore, the axial traction length of the wrapping tape is very small. When rotating at high speed, the wind resistance becomes extremely small, thereby effectively reducing the vibration of the wrapping tape, greatly reducing noise, and effectively improving the stability of rotation. Higher speed rotation is possible, thereby improving work efficiency.

[0011] Preferably, the traction assembly further includes a driving wheel and a driven wheel. The driving wheel is coaxially and rotatably fitted onto one end of the rotating shaft. The driven wheel is coaxially fixed to one of the pressure rollers of the two pressure roller groups. The driving wheel and the driven wheel are in rolling contact. The first drive mechanism can drive the driving wheel to rotate. By setting the driving wheel and the driven wheel, and making the driving wheel in rolling contact with the two driven wheels, the first drive mechanism can be used to drive the driving wheel to rotate, thereby achieving the purpose of driving the two pressure roller groups to rotate simultaneously, thus achieving the effect of dual traction of the strapping and improving the stability of the strapping conveyor.

[0012] Specifically, the first drive mechanism includes a first servo motor, a first driving pulley, a first driven pulley, and a first synchronous belt. The first driving pulley is located at the output end of the first servo motor. The first driven pulley is coaxially and rotatably mounted on the rotating shaft. The first driven pulley is coaxially fixed to the driving pulley. The first synchronous belt surrounds the first driving pulley and the first driven pulley. By coaxially and rotatably mounting the first driven pulley on the rotating shaft and fixing it coaxially to the driving pulley, and then using the first driving pulley and the first synchronous belt to drive the first driven pulley to rotate, the pressure roller group can be driven to rotate on its own axis without affecting its revolution around the central axis of the turntable, thus achieving traction of the strapping. Its structure is simple and its control is very convenient.

[0013] Preferably, the outer wall of the rotating shaft is provided with a through groove along the central axis, the through groove extending from the outer side of the rotating shaft to the end face near the pressure roller assembly. This allows the strapping to be conveyed forward while rotating with the rotating shaft, and the air resistance encountered within the through groove is small, resulting in more stable conveying.

[0014] Preferably, the traction mechanism further includes a guide wheel, which is located at the end of the rotating shaft away from the pressure roller assembly to guide the strapping into the through groove. Guided by the guide wheel, the strapping can accurately and stably enter the rotating shaft, improving operational smoothness.

[0015] Preferably, the traction assembly further includes a second steering wheel, which is disposed on the turntable to guide the strapping to the pressure roller assembly; the distance from the second steering wheel to the center of the turntable is less than the distance from the pressure roller assembly to the center of the turntable. By providing the second steering wheel, the strapping can be smoothly and accurately conveyed to the pressure roller assembly after entering the turntable, thereby improving the smoothness and stability of the strapping conveyor.

[0022] To illustrate the technical content, structural features, and effects of the present invention in detail, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0023] like Figures 1 to 5 As shown, the dual-axis supported power wrapping machine 100 of the present invention includes a traction mechanism 1, a tape feeding mechanism 2, and a central rod 3. The tape feeding mechanism 2 includes a main shaft 21, a tape feeding shaft 22, a rotating bracket 23, a tape feeding reel 24, a bracket drive mechanism 25, and a reel drive mechanism 26. The main shaft 21 is coaxially and rotatably sleeved around the tape feeding shaft 22. The center of one side of the tape feeding reel 24 is connected to one end of the tape feeding shaft 22, and the center of the other side of the tape feeding reel 24 is coaxially and rotatably connected to the rotating shaft 11 of the traction mechanism 1. The center of one side of the rotating bracket 23 is fixedly connected to one end of the main shaft 21, and the center of the other side of the rotating bracket 23 is coaxially and fixedly connected to the rotating shaft 11. The tape feeding shaft 22 has a first through hole 22a extending through both ends, and the rotating shaft 11 has a second through hole 11a extending through both ends. The central rod 3 passes through the first through hole 22a and the second through hole 11a to allow the core wire to be conveyed forward from inside the central rod 3. The tape reel drive mechanism 26 drives the tape feeding shaft 22 to rotate, thereby driving the tape feeding reel 24 to release the wrapping tape. The bracket drive mechanism 25 drives the main shaft 21 to rotate, thereby causing the traction mechanism 1 to rotate so that the wrapping tape wraps around the core wire.

[0024] Please see Figure 1 and Figure 2More specifically, the center of one side of the tape reel 24 is abutted by the top of the end of the tape feeding shaft 22, and one end of the tape feeding shaft 22 is provided with an eccentric pin (not shown in the figure). The pin is inserted into one side of the tape feeding reel 24, thereby both circumferentially positioning the tape feeding reel 24 and driving the tape feeding reel 24 to rotate circumferentially. A connecting member 27 is provided between the other side of the tape feeding reel 24 and the rotating shaft 11. One end of the connecting member 27 is tightly abutted and fixedly connected to the center of the other side of the tape feeding reel 24, and the other end of the connecting member 27 is rotatably connected to the rotating shaft 11 through a bearing. Specifically, the connector 27 includes a top head 271 and a top head seat 272. One end of the top head 271 is connected to the center of the other side of the tape reel 24 by abutting. The other end of the top head 271 is fixed to the top head seat 272 by threads and screws (not shown in the figure). The top head seat 272 is rotatably connected to the rotating shaft 11 by the bearing 2a.

[0025] Please see again Figure 1 and Figure 2 The tape feeding mechanism 2 further includes a mounting base 28, on which the main shaft 21 is mounted via bearings. The rotating support 23 includes a front plate 231, a rear plate 232, and a connecting rod 233 connecting the front plate 231 and the rear plate 232. A guide roller 234 is also provided between the front plate 231 and the rear plate 232. The tape feeding reel 24, the guide roller 234, and the connecting rod 233 are arranged sequentially from the inside to the outside along the radius of the rotating support 23. A guide cylinder 29 is provided between the tape feeding reel 24 and the traction mechanism 1. Specifically, there are two guide cylinders 29. One guide cylinder 29 is located on the connecting rod 233 and between the front plate 231 and the rear plate 232 to guide the tape drawn from the guide roller 234. The other guide cylinder 29 is located between the front plate 231 and the traction mechanism 1, offset from the center of the front plate 231. The central axis of the steering roller 234 is parallel to the central axis of the main shaft 21, and the central axis of the steering roller 234 is perpendicular to the central axis of one of the guide cylinders 29. The central axis of the other guide cylinder 29 is perpendicular to the central axes of both the steering roller 234 and the other guide cylinder 29. A belt-passing hole 231a is provided off-center on the front plate 231 of the rotating bracket 23 near the traction mechanism 1. The belt passes through the steering roller 234 and the other guide cylinder 29, then through the belt-passing hole 231a, then around the other guide cylinder 29, and finally extends onto the traction mechanism 1. The front plate 231 has a conical structure to reduce wind resistance during rotation.

[0026] like Figure 2As shown, the tape feeding mechanism 2 also includes a braking device 230, which stops the rotation of the main shaft 21. The braking device 230 is mounted on the mounting base 28 and brakes the main shaft 21 or the second driven pulley 253 of the bracket drive mechanism 25. The braking device 230 can be an electromagnetic brake; it can also be a brake disc brake, which only requires connecting the brake disc to the second driven pulley 253 of the bracket drive mechanism 25; or it can be a pneumatic brake.

[0027] Please see Figures 3 to 6 The traction mechanism 1 includes a rotating shaft 11, a turntable 12, a traction assembly 13, a first drive mechanism 14, and a base 17. The outer side of the rotating shaft 11 is rotatably mounted on the base 17 via bearings. The rotating shaft 11 is coaxially sleeved with the central rod 3, and bearings are provided between both ends of the rotating shaft 11 and the central rod 3 to allow the rotating shaft 11 to rotate relative to the central rod 3. The traction assembly 13 includes a first steering wheel 131 and a pressure roller assembly 132 pivotally connected to one side of the turntable 12 in a centrally symmetrical manner. Each pressure roller assembly 132 has two pressure rollers 132a that press against each other and are in rolling contact. The rotation shaft 132b of the pressure rollers 132a is parallel to the rotating shaft 11. The turntable 12 is coaxially fixed to one end of the rotating shaft 11. The first steering wheel 131 is disposed on the turntable 12, and the center distance between the first steering wheel 131 and the turntable 12 is less than the center distance between the pressure roller assembly 132 and the turntable 12. The first drive mechanism 14 drives the pressure roller assembly 132 to rotate, so that the pressure roller assembly 132 pulls the wrapping tape 300 forward, and the wrapping tape 300 extends to the core wire 200 through the first steering wheel 131; the second drive mechanism 15 drives the rotating shaft 11 to rotate, so that the wrapping tape 300 rotates and wraps around the core wire 200.

[0028] Please see Figure 5 and Figure 6 Specifically, the traction assembly 13 further includes a first bracket 133, which is fixedly mounted on the turntable 12. The first steering wheel 131 is pivotally connected to the first bracket 133, and the pivot axis intersects the projection of the rotation axis 132b of the pressure wheel 132a of the pressure wheel assembly 132 on the horizontal plane. In this embodiment, the two axes are perpendicular. In this embodiment, there are two first steering wheels 131, which are arranged along the central axis of the rotation axis 11, and the strap 300 needs to pass around the two first steering wheels 131.

[0029] Please see again Figure 5 and Figure 6The traction assembly 13 further includes a second steering wheel 134 and a second bracket 135. The second steering wheel 134 is disposed on the turntable 12 and located on the side opposite to the first steering wheel 131, to guide the strap 300 to the pressure roller assembly 132. Specifically, the second bracket 135 is fixedly disposed on the turntable 12, and the second steering wheel 134 is pivotally connected to the second bracket 135. The pivot axis intersects the projection of the rotation axis 132b of the pressure roller 132a of the pressure roller assembly 132 on the horizontal plane; in this embodiment, the two are perpendicular. Furthermore, the pivot axis of the second steering wheel 134 is parallel to the pivot axis of the first steering wheel 131. The distance from the second steering wheel 134 to the center of the turntable 12 is less than the distance from the pressure roller assembly 132 to the center of the turntable 12. The number of second steering wheels 134 can be one or two, arranged along the central axis of the rotation shaft 11. The strapping tape 300 needs to pass around at least one of the second steering wheels 134 before extending to the pressure roller group 132. By setting the second steering wheels 134, the strapping tape 300 can be smoothly and accurately conveyed to the pressure roller group 132 after entering the turntable 12, thereby improving the smoothness and stability of the strapping tape 300 conveying.

[0030] like Figure 5 As shown, the outer wall of the rotating shaft 11 is provided with a through groove 111 along the central axis. The through groove 111 extends from the outer side of the rotating shaft 11 to the end face near the pressure roller assembly 132. The through groove 111 is open on the outer side of the rotating shaft 11 to facilitate the threading of the strapping 300 onto the pressure roller assembly 132 before operation. The opening of the through groove 111 after passing through the rotating shaft 11 is located between the center of the second steering wheel 134 and the rotating shaft 11. That is, the distance from the opening of the through groove 111 to the center of the rotating shaft 11 is less than the distance from the second steering wheel 134 to the rotating shaft 11, so that the strapping 300 can easily bypass the second steering wheel 134 after passing through the through groove 111. By setting the through groove 111, the strapping 300 can be conveyed forward while rotating with the rotating shaft 11, and the wind resistance encountered by the strapping 300 in the through groove 111 is reduced, resulting in more stable conveying. In addition, the traction mechanism 1 also includes a guide wheel 16, which is pivotally connected to the end of the rotating shaft 11 away from the pressure roller assembly 132, to guide the strap 300 from the outside into the through groove 111. The pivot axis of the guide wheel 16 is perpendicular to the central axis of the rotating shaft 11. Guided by the guide wheel 16, the strap 300 can accurately and stably enter the rotating shaft 11, improving the smoothness of operation.

[0031] Please see again Figure 4 and Figure 5The traction assembly 13 further includes a driving wheel 136 and driven wheels 137. The driving wheel 136 is coaxially and rotatably fitted onto one end of the rotating shaft 11. There are two driven wheels 137, each coaxially fixed to one of the pressure rollers 132a of the two pressure roller groups 132. The driving wheel 136 simultaneously rolls in contact with both driven wheels 137. The first drive mechanism 14 can drive the driving wheel 136 to rotate, thereby driving the two driven wheels 137, and further causing the pressure roller 132a to rotate. By setting the driving wheel 136 and driven wheels 137, and making the driving wheel 136 roll in contact with the two driven wheels 137, the first drive mechanism 14 can drive the driving wheel 136 to rotate, achieving the purpose of driving the two pressure roller groups 132 to rotate simultaneously, thereby achieving the effect of dual traction of the strapping 300 and improving the stability of the strapping 300 conveying. In this embodiment, the driving wheel 136 and the driven wheel 137 can be rubber wheels or gears; any wheel set that can transmit driving force is applicable.

[0032] like Figure 4 and Figure 5 As shown, the first drive mechanism 14 includes a first servo motor 141, a first driving pulley 142, a first driven pulley 143, and a first synchronous belt 144. The first servo motor 141 can be mounted on the base 17. The first driving pulley 142 is mounted on the output end of the first servo motor 141. The first driven pulley 143 is coaxially and rotatably mounted on the rotating shaft 11 through a bearing. The first driven pulley 143 is coaxially fixed with the driving pulley 136. The first synchronous belt 144 surrounds the first driving pulley 142 and the first driven pulley 143. By coaxially and rotatably sleeved on the rotating shaft 11 and coaxially fixed with the driving wheel 136, and then using the first driving pulley 142 and the first synchronous belt 144 to drive the first driven pulley 143 to rotate, the pressure roller group 132 can be driven to rotate on its own axis without affecting the revolution of the pressure roller group 132 around the central axis of the turntable 12, thereby achieving traction of the wrapping belt 300. Its structure is simple and very convenient to control.

[0033] For example Figure 1 and Figure 2As shown, the bracket drive mechanism 25 includes a second servo motor 251, a second driving pulley 252, a second driven pulley 253, and a second synchronous belt 254. The second servo motor 251 can be mounted on the mounting base 28. The second driving pulley 252 is located at the output end of the second servo motor 251, the second driven pulley 253 is coaxially fixed to the main shaft 21, and the second synchronous belt 254 surrounds the second driving pulley 252 and the second driven pulley 253.

[0034] For example Figure 1 and Figure 2 As shown, the pulley drive mechanism 26 includes a third servo motor 261, a third driving pulley 262, a third driven pulley 263, and a third synchronous belt 264. The third servo motor 261 can be mounted on the mounting base 28. The third driving pulley 262 is located at the output end of the third servo motor 261, the third driven pulley 263 is coaxially fixed on the belt feeding shaft 22, and the third synchronous belt 264 surrounds the third driving pulley 262 and the third driven pulley 263.

[0035] In summary and in combination Figure 1 The working principle of the wrapping mechanism 100 of the present invention will be described in detail below:

[0036] First, for the traction mechanism 1, the guide wheel 16, base 17, first driven pulley 143, driving wheel 136, and turntable 12 are sequentially arranged on the rotating shaft 11 along the conveying direction of the wrapping tape 300. The tape release mechanism 2 is located at one end near the guide wheel 16. Initially, the core wire 200 and wrapping tape 300 need to be guided through the threading process. Specifically, the core wire 200 is threaded from one end of the tape release mechanism 2 into the central rod 3, and extends through the turntable 12. The conveying direction of the core wire 200 is from one end of the tape release mechanism 2 to one end of the turntable 12. Of course, the conveying direction of the core wire 200 can also be from one end of the turntable 12 to one end of the tape release mechanism 2. The wrapping tape 300 is first released from the tape release reel 24, then passes around the steering roller 234 and the two guide cylinders 29, and then passes around the guide wheel 16 before entering the through groove 111. Next, the wrapping tape 300 passes through the through slot 111 and exits from the outside of the turntable 12. Then, the wrapping tape 300 goes around a second guide roller 134 and passes between the two pressure rollers 132a of the pressure roller group 132 on that side. After that, the wrapping tape 300 goes around the pressure rollers 132a and extends to the pressure roller group 132 on the other side, passing between the two pressure rollers 132a of the pressure roller group 132 on that side. Finally, the wrapping tape 300 goes around the two first guide rollers 131 and wraps around the core wire 200.

[0037] During operation, the core wire 200 is continuously output forward under the traction of external equipment. Simultaneously, the first servo motor 141, the second servo motor 251, and the third servo motor 261 are activated. The first servo motor drives the first drive pulley 142, which in turn drives the first driven pulley 143 and the drive pulley 136 via the first synchronous belt 144. The drive pulley 136 drives the driven pulley 137, which in turn drives the pressure roller 132a connected to it. At this time, both pressure roller groups 132 rotate simultaneously, thus providing dual traction force to drive the tape 300 forward. Additionally, the third servo motor 261 drives the third drive pulley 262, which in turn drives the tape feeding shaft 22 to rotate via the third synchronous belt 264 and the third driven pulley 263. The tape feeding shaft 22 drives the tape feeding reel 24 to rotate and continuously feed the tape. Simultaneously, the second servo motor 251 drives the second drive pulley 252, which in turn drives the rotating bracket 23 to rotate via the second synchronous belt 254 and the second driven pulley 253. The rotating bracket 23 then drives the rotating shaft 11 to rotate, which in turn drives the turntable 12 to rotate. At this time, the pressure rollers 132a of the pressure roller group 132 rotate around their own central axis and simultaneously revolve around the center of the rotating shaft 11, causing the wrapping tape 300 to continuously wrap around the core wire 200 while continuously outputting output.

[0038] Compared with the prior art, this invention connects the center of the other side of the tape reel 24 coaxially and rotatably with the rotating shaft 11 of the traction mechanism 1, and the center of the other side of the rotating bracket 23 is fixedly coaxially connected with the rotating shaft 11 of the traction mechanism. This allows the rotating shaft 11 of the traction mechanism 1 to rotate with the rotating bracket 23, while providing a support point on the other side of the rotating bracket 23, and the rotating shaft 11 of the traction mechanism 1 providing a support point on the other side of the tape reel 24. Therefore, the forces on both ends of the rotating bracket 23 and the tape reel 24 are balanced, resulting in smoother operation and enabling high-speed operation. Compared with a single-sided support structure, this invention effectively improves production efficiency, greatly reduces vibration and noise, and reduces wear on components, heat generation, and failure rate, effectively extending service life. Furthermore, by symmetrically arranging two pressure roller groups 132 on the turntable 12, and by providing a first steering wheel 131 on the turntable 12 such that the center distance from the first steering wheel 131 to the turntable 12 is less than the center distance from the pressure roller groups 132 to the turntable 12, the two pressure roller groups 132 and the first steering wheel 131 are essentially on the same radial plane. When the wrapping tape 300 wraps around the two pressure roller groups 132 and the first steering wheel 131 to cover the core wire 200, the axial distance from the wrapping tape 300 leading out from the rotating shaft 11 to the core wire 200 is very short. Therefore, the axial traction length of the wrapping tape 300 is very small, making it very easy and convenient to thread. When rotating at high speed, the wind resistance becomes extremely small, thereby effectively reducing the vibration of the wrapping tape 300, greatly reducing noise, and effectively improving the stability of rotation, allowing for higher speed rotation and thus improving work efficiency. In addition, since two pressure roller groups 132 are used to convey the tape, the first pressure roller group 132 can directly pull the tape, and the first pressure roller group 132 can isolate the tape release reel 24, thereby preventing changes in the tape speed or tape amount released by the tape release reel 24 from affecting the tape 300 that will be wrapped around the core wire 200. Therefore, the two pressure roller groups 132 can completely shield the influencing factors other than the two pressure roller groups 132, thereby enabling the tape 300 to be output stably and ensuring the stability of the tape.

[0039] The above-disclosed examples are merely preferred embodiments of the present invention and should not be construed as limiting the scope of the present invention. Therefore, any equivalent variations made in accordance with the claims of the present invention shall still fall within the scope of the present invention.
