Description

Technical Field

[0001] This utility model relates to the field of wrapping machine technology, specifically a high-speed wrapping machine with an internal strap. Background Technology

[0002] In the manufacturing process of power cables, wrapping is a key step, which is used to tightly spirally wrap materials such as shielding tape, insulation tape or protective tape around the cable conductor or core wire to give the cable specific electrical properties, mechanical properties or protective characteristics.

[0003] According to CN217690643U, a novel cable wrapping machine is disclosed. This technology discloses a technical solution including "a wrapping machine body, a rotating device, and a rotating bracket rotatably mounted on the wrapping machine body. The rotating device is connected to the rotating bracket and drives the rotating bracket to rotate. Cable conduits are fixedly mounted on the wrapping machine body at both ends of the rotating bracket, and the cable passes through the cable conduits. At least one wrapping device is set on the rotating bracket to wrap the exposed cable between the cable conduits with wrapping tape." This technology has the advantages of "preventing cable swaying during wrapping, increasing wrapping speed, and increasing productivity. At the same time, it can realize multi-layer wrapping tape wrapping, saving on equipment procurement."

[0004] Traditional double-disc eccentric wrapping equipment has the reels installed on the outside of the rotating body. When the equipment is running at high speed, the centrifugal force causes the reels to swing outward, which increases the vibration of the equipment and makes the operation unstable. This seriously restricts the improvement of wrapping speed and limits production efficiency. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a high-speed wrapping machine with an internally mounted tape. Through the internal structure and multi-point synchronous locking mechanism, it achieves high-speed and stable operation of the tape reel and rapid clamping. Combined with a multi-level adjustable guide belt system, it ensures precise wrapping of the tape, significantly improving wrapping quality and production efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-speed wrapping machine with an internal tape, comprising a wrapping machine and used for wrapping cable tape, the wrapping machine comprising:

[0007] The main components include support seats that are fixed at both ends of the base, a guide tube fixed on the support seats, a frame rotatably mounted between the two support seats, and a power device mounted on the base for driving the frame to rotate.

[0008] The wrapping assembly includes a mounting base on the inner walls of both ends of the frame, which is rotatably mounted via bearings. A connecting plate is slidably mounted inside the mounting base. Three support plates are fixed on the connecting plate in a circular arrangement. An oblique groove is opened inside the support plate. A lock head is slidably mounted on the support plate through the oblique groove. The lock head is slidably mounted through the mounting base. A threaded rod is threaded through the mounting base. The inner end of the threaded rod is rotatably connected to the connecting plate. A handwheel is fixed to the outer end of the threaded rod. A belt disc is installed inside the bearing. A sleeve is fixed in the middle of the outer end of the belt disc. Three lock holes are opened on the sleeve in a circular arrangement and cooperate with the lock head.

[0009] The guide belt assembly is mounted on the frame and is used to guide and adjust the conveying path and wrapping angle of the belt.

[0010] Preferably, the guide belt assembly includes a bracket slidably mounted on a frame, a knob bolt threaded onto the bracket, a guide rail fixed to the inner end of the bracket, a knob screw rotatably mounted inside the guide rail, a shaft seat slidably mounted on the guide rail and threaded onto the knob screw, a shaft bracket rotatably mounted on the upper end of the shaft seat, and two guide rollers rotatably mounted between the two ends inside the shaft bracket.

[0011] Preferably, the guide belt assembly further includes a worm gear fixed to the lower end of the shaft bracket, and a knob worm is rotatably mounted between the two ends inside the shaft seat and meshes with the worm gear for transmission.

[0012] Preferably, the wrapping assembly further includes three protrusions fixed to the inner wall of the mounting base and arranged circumferentially, and the outer wall of the connecting plate has a groove that cooperates with the protrusions.

[0015] Beneficial effects

[0016] This utility model provides a high-speed wrapping machine with an internal strap. Compared with the prior art, it has the following advantages:

[0017] Beneficial effects:

[0018] 1. When the handwheel drives the threaded rod, the connecting plate moves axially along the mounting base, causing the three circumferentially arranged support plates to move synchronously. The inclined grooves in the support plates convert the axial displacement into the radial movement of the lock head, allowing the lock head to accurately insert into or exit the lock hole on the sleeve, realizing the rapid clamping and automatic centering of the belt reel. This structure effectively suppresses vibration during high-speed rotation through a multi-point synchronous locking mechanism, ensuring the stability of the belt reel and frame rotating synchronously. At the same time, it simplifies the operation process and significantly improves production efficiency and equipment reliability.

[0019] 2. The overall position is adjusted laterally by sliding the bracket along the frame and quickly locked in place by the knob bolts; the knob screw on the guide rail drives the shaft seat to move, and the shaft seat drives the guide roller on the shaft frame to adjust the radial position. The two parallel guide rollers form a strip guide channel, which can effectively eliminate the sway phenomenon during the strip conveying process; when the knob worm is rotated, the meshing transmission of the worm wheel drives the shaft frame and guide roller to rotate around the vertical axis, thereby precisely adjusting the guide angle of the guide roller; the worm wheel mechanism has a reverse self-locking characteristic, which can effectively prevent the angle deviation caused by equipment vibration, ensuring that the strip is always wound on the cable core at the best wrapping angle, thus avoiding strip twisting and deformation.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1 - Figure 5 This utility model provides a technical solution: a high-speed wrapping machine with an internal tape, including a wrapping machine 1 and used for wrapping cable tape, the wrapping machine 1 including:

[0028] The main component 11 includes a support seat 112 fixed at both ends of the base 111, a conduit 113 fixed on the support seat 112, a frame 114 rotatably mounted between the two support seats 112, and a power device 115 mounted on the base 111 for driving the frame 114 to rotate.

[0029] The wrapping assembly 12 includes a mounting base 122 on the inner walls of both ends of the frame 114, which is rotatably mounted via bearings 121. A connecting plate 123 is slidably mounted inside the mounting base 122. Three circumferentially arranged support plates 124 are fixed on the connecting plate 123. An oblique groove 125 is opened inside the support plate 124. A lock head 126 is slidably mounted on the support plate 124 via the oblique groove 125. The lock head 126 is slidably mounted through the mounting base 122. A threaded rod 127 is threaded through the mounting base 122. The inner end of the threaded rod 127 is rotatably connected to the connecting plate 123. A handwheel 128 is fixed to the outer end of the threaded rod 127. A belt disc 129 is installed on the inner end of the bearing 121. A sleeve 1210 is fixed in the middle of the outer end of the belt disc 129. Three circumferentially arranged locking holes 1211 are opened on the sleeve 1210 and cooperate with the lock head 126.

[0030] The guide belt assembly 13 is mounted on the frame 114 and is used to guide and adjust the conveying path and wrapping angle of the belt.

[0031] In this embodiment, when the handwheel 128 drives the threaded rod 127, the connecting plate 123 moves axially along the mounting base 122, causing the three circumferentially arranged support plates 124 to move synchronously. The inclined groove 125 in the support plate 124 converts the axial displacement into the radial movement of the locking head 126, so that the locking head 126 can accurately insert or withdraw from the locking hole 1211 on the sleeve 1210, realizing the quick clamping and automatic centering of the pulley 129. This structure effectively suppresses the vibration during high-speed rotation through the multi-point synchronous locking mechanism, ensuring the stability of the synchronous rotation of the pulley 129 and the frame 114, while simplifying the operation process and significantly improving production efficiency and equipment reliability.

[0032] Specifically, the guide belt assembly 13 includes a bracket 131 slidably mounted on the frame 114, a knob bolt 132 threadedly mounted on the bracket 131, a guide rail 133 fixed to the inner end of the bracket 131, a knob screw 134 rotatably mounted inside the guide rail 133, a shaft seat 135 slidably mounted on the guide rail 133 and threadedly mounted to the knob screw 134, a shaft bracket 136 rotatably mounted on the upper end of the shaft seat 135, and two guide rollers 137 rotatably mounted between the two ends inside the shaft bracket 136.

[0033] In this embodiment, the overall position is adjusted laterally by sliding the bracket 131 along the frame 114, and is quickly locked and fixed by the knob bolt 132; the knob screw 134 on the guide rail 133 drives the shaft seat 135 to move, the shaft seat 135 drives the guide roller 137 on the shaft frame 136 to adjust the radial position, and the two parallel guide rollers 137 form a strip guide channel, which can effectively eliminate the sway phenomenon in the strip conveying process.

[0034] Specifically, the guide belt assembly 13 also includes a worm gear 138 fixed to the lower end of the shaft bracket 136, and a knob worm 139 is rotatably mounted between the two ends inside the shaft seat 135 and meshes with the worm gear 138 for transmission.

[0035] In this embodiment, when the worm gear 139 is rotated, the worm wheel 138 drives the shaft frame 136 and guide roller 137 to rotate around the vertical axis, thereby precisely adjusting the guide angle of the guide roller 137. The worm wheel mechanism has a reverse self-locking characteristic, which can effectively prevent the angle deviation caused by equipment vibration and ensure that the strip is always wound on the cable core at the best wrapping angle, thus avoiding the twisting and deformation of the strip.

[0036] Specifically, the wrapping assembly 12 also includes three protrusions 1212 that are fixed to the inner wall of the mounting base 122 and arranged circumferentially, and the outer wall of the connecting plate 123 has a groove that cooperates with the protrusions 1212.

[0037] In this embodiment, when the rotating handwheel 128 drives the threaded rod 127, the connecting plate 123 is constrained by the cooperation between the protrusion 1212 and the groove, and can move purely axially within the mounting base 122 without rotating circumferentially, thus ensuring that the three support plates 124 advance synchronously.

[0038] Specifically, the inner end of the lock head 126 is a wedge-shaped surface, and the lock hole 1211 is a wedge-shaped hole that matches it.

[0039] Specifically, the inclined groove 125 on the support plate 124 is provided with a wear-resistant bushing, and the inner end of the lock head 126 slides in cooperation with the wear-resistant bushing.

[0040] The working principle and usage process of this utility model are as follows: First, the power equipment 115 drives the frame 114 to rotate at high speed through synchronous belt transmission, and drives the belt reel 129 in the wrapping assembly 12 to rotate synchronously. After the wrapping tape is precisely guided by the guide roller 137 of the guide belt assembly 13, it forms a precise spiral wrapping layer under the combined action of the rotation of the frame 114 and the axial movement of the cable. The concentricity of the cable and the rotating frame 114 is ensured by the guide tube 113. The design of the belt reel 129 inside the frame 114 converts the centrifugal force into the structural pretension force. With the multi-stage adjustment function of the guide belt assembly 13, the stable conveying and precise winding of the wrapping tape under high speed is achieved.
