Description

Technical Field

[0001] This utility model belongs to the field of optical cable production technology, and specifically relates to an optical cable production wrapping machine. Background Technology

[0002] A wrapping machine is a widely used piece of equipment in the wire and cable industry, such as wires, cables, and optical cables. Its main function is to wrap a protective material around the outside of the conductors, optical cables, or electrical cables to protect the rubber insulation layer or sheath of the conductors or optical cables. It mainly consists of an unwinding frame, a traction frame, and a take-up frame. The traction frame is located on one side of the unwinding frame and is used to receive and pull the cable and control the wrapping tension. The cable is generally passed through the axis of the unwinding frame and then through the traction frame. The unwinding wheel on the unwinding frame rotates, driving the wrapping head to wrap and encase the cable.

[0003] In existing technologies, when the wrapping head of the wrapping machine drives the wrapping tape to rotate at high speed around the outer wall of the cable, the cable is affected by the centrifugal force transmitted by it, which will cause the cable to tend to detach from the center of the circle. Moreover, the angle of the wrapping head is not designed to be synchronized with the unwinding wheel. The wrapping tape will apply a tangential tension to the cable. After this force is superimposed with the centrifugal force, it will form a resultant force with periodic directional changes. It can be clearly observed that the cable swings back and forth in the circumferential plane, affecting the tension stability. This causes the cable to rub against the cable inlet port of the traction frame for a long time, resulting in double wear of both. This not only affects the wrapping quality of the cable, but also reduces the service life of the traction frame. Utility Model Content

[0004] The purpose of this invention is to provide a fiber optic cable production wrapping machine. The rollers dynamically adhere to the cable through a compression spring, converting sliding friction into rolling friction. The double-door panel is equipped with staggered push-pull frames and anti-wear pads, forming a guide channel when closed. The two work together to prevent the cable from deviating to the left or right and avoid mutual wear between the cable and the traction frame. It takes into account multiple specifications, low wear, and high stability, solving the pain points of high cable friction and easy deviation of the traction frame in traditional wrapping machines.

[0005] The specific technical solution adopted by this utility model is as follows:

[0006] A fiber optic cable production wrapping machine includes a traction frame and a U-shaped frame plate detachably mounted at its cable threading port. The U-shaped frame plate contains an adaptive elastic guide wheel mechanism, comprising:

[0007] Two rollers are arranged symmetrically in a vertical direction, and their axes are slidably connected at their center.

[0008] A through slot is formed in the side wall of the U-shaped frame plate, with the upper axle slidably connected to the through slot and the lower axle fixed to the U-shaped frame plate;

[0009] Rotate the retaining ring located on the outer wall of the axle, and the roller is elastically connected to the retaining ring through compression springs at both ends;

[0010] The U-shaped frame plate is slidably provided with an anti-deviation door panel mechanism at its open end, including:

[0011] The double-door panel has an alternating sliding frame on the inside, and the inner wall of the sliding frame is equipped with an anti-wear pad.

[0012] The top of the U-shaped frame is equipped with a manual lifting mechanism, including a span, and the top of the span is equipped with a connecting plate, which is slidably connected to the span through connecting rods at both ends.

[0013] The manual lifting mechanism also includes an adjusting screw that is rotatably connected to the middle of the connecting plate. The adjusting screw is threadedly connected to the cross frame, and the connecting plate is linked to the upper wheel axle through the connecting rod.

[0014] One end of the U-shaped frame plate is provided with a quick-release connection mechanism, including: a rotating ring, the end of which is fixed with a screw tube that is threaded to the cable threading port of the traction frame;

[0015] The insert plates, symmetrically fixed to both sides of the U-shaped frame plate, are used to engage with the insert frame located at the wire-passing port of the traction frame.

[0016] The anti-deviation door panel mechanism further includes: a fixing plate fixed to the end of the door panel, and the push-pull frame is elastically connected to the fixing plate through a tension spring;

[0017] A limiting rod is symmetrically arranged on the outer wall of the door panel. The limiting rod slides with the U-shaped frame plate, and the door panel is simultaneously threadedly connected to the U-shaped frame plate through an adjusting screw.

[0018] The technical effects achieved by this utility model are as follows: the roller dynamically adheres to the cable through the compression spring, converting sliding friction into rolling friction; while the double-door panel is equipped with staggered push-pull frames and anti-wear pads, forming a guide channel when closed. The two work together to prevent the cable from deviating to the left or right, avoid mutual wear between the cable and the traction frame, and take into account multiple specifications, low wear and high stability, solving the pain points of high cable friction and easy deviation of the traction frame of traditional wrapping machine.

[0024] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0025] like Figures 1-3 As shown, a fiber optic cable production wrapping machine includes a traction frame 1 and a U-shaped frame plate 2 detachably installed at its cable threading port. One end of the U-shaped frame plate 2 is provided with a quick-release connection mechanism, including: a rotating ring 210, the end of which is fixed with a threaded tube 211 that engages with the cable threading port of the traction frame 1; symmetrically fixed insert plates 212 on both sides of the U-shaped frame plate 2 for insertion into a frame 101 located at the cable threading port of the traction frame 1; and a sliding anti-deviation door plate mechanism at the open end of the U-shaped frame plate 2. Includes: a double-leaf door panel 3, with an alternating sliding push-pull frame 301 on its inner side, and an anti-wear pad on the inner wall of the push-pull frame 301; the anti-deviation door panel mechanism also includes: a fixing plate 302 fixed to the end of the door panel 3, the push-pull frame 301 being elastically connected to the fixing plate 302 via a tension spring 303; and limiting rods 304 symmetrically arranged on the outer wall of the door panel 3, the limiting rods 304 slidingly engaging with the U-shaped frame plate 2, and the door panel 3 being threadedly connected to the U-shaped frame plate 2 via an adjusting screw 305.

[0026] According to the above structure, by aligning the insert plate 212 with the frame 101 and inserting it, aligning the screw tube 211 with the inlet port of the traction frame 1, and rotating the rotating ring 210, the screw tube 211 is screwed and fixed to the port. At the same time, the insert plate 212 is continuously inserted into the frame 101. The insertion of the insert plate 212 and the frame 101 can keep the U-shaped frame plate 2 in a horizontal state. The cable passes through the two push-pull frames 301 and the two rollers 201 in sequence, and then enters the traction frame 1 through the screw tube 211. By rotating the adjusting screw 305, the door plate 3 is moved. The limiting rod 304 slides at the same time and performs auxiliary fixation to prevent the door plate 3 from shaking as the adjusting screw 305 rotates.

[0027] Furthermore, the two door panels 3 move closer to each other, narrowing the width between the two sliding frames 301 until it matches the cable diameter, but not completely clamping it, allowing the cable to still move vertically freely. The two sliding frames 301 adopt an "interlaced sliding connection," that is, the inner flange of one sliding frame 301 is embedded in the groove of the other sliding frame 301. When the door panel 3 is closed, the sliding frames 301 form a narrow rectangular channel, and the cable must move along the axis of this channel. At the same time, the anti-abrasion pads of the sliding frames 301 can be made of materials such as nylon, silicone, and polyurethane elastomer to prevent the cable from rubbing against the sliding frames 301 and protect the cable sheath. If the cable still undergoes slight displacement due to tension changes, such as expansion or vibration, the elasticity of the tension spring 303 will dynamically adjust the position of the sliding frame 301, making it slide vertically along the door panel 3, "pulling" the cable back to the center and adjusting its position.

[0028] See attached document Figures 1-3 The U-shaped frame plate 2 is equipped with an adaptive elastic guide wheel mechanism, including: two vertically symmetrically arranged rollers 201, with a wheel axle 202 slidably connected to their axis; a through slot 205 through the side wall of the U-shaped frame plate 2, with the upper wheel axle 202 slidably connected to the through slot 205 and the lower wheel axle 202 fixed to the U-shaped frame plate 2; a retaining ring 203 rotatably disposed on the outer wall of the wheel axle 202, with the rollers 201 elastically connected to the retaining ring 203 through compression springs 204 at both ends; the top of the U-shaped frame plate 2 is equipped with a manual lifting mechanism, including a cross frame 206, with a connecting plate 207 at the top of the cross frame 206, the connecting plate 207 being slidably connected to the cross frame 206 through connecting rods 208 at both ends, the manual lifting mechanism also including an adjusting screw 209 rotatably connected to the middle of the connecting plate 207, the adjusting screw 209 being threadedly connected to the cross frame 206, and the connecting plate 207 being linked to the upper wheel axle 202 through the connecting rods 208.

[0029] According to the above structure, rotating the adjusting screw 209 lifts the upper axle 202 via the connecting plate 207 and connecting rod 208, allowing it to slide upwards along the through groove 205. This adjusts the distance between the two rollers 201, adapting to cables of different diameters and keeping the rollers 201 in contact with the cables. The sliding connection between the rollers 201 and the axle 202 means that the rollers 201 reduce friction by rolling (rotation) and can slide axially along the axle 202 (similar to curtain track pulleys in the prior art: the pulleys can slide and rotate along the crossbar to adapt to the opening and closing of the curtains).

[0030] Furthermore, when the cable deviates and sways during traction, the roller 201 will rotate around the wheel axle 202, converting the cable's sliding into rolling, and driving the compression spring 204 to rotate together. The compression spring 204 allows the roller 201 to move slightly in the horizontal direction and extend and retract left and right, providing a rebound force through compression or extension, so that the roller 201 always follows and fits the cable, thereby achieving low-friction transmission and resistance to radial deviation.

[0031] The working principle of this utility model is as follows: by aligning the insert plate 212 with the frame 101 and inserting it, aligning the screw tube 211 with the inlet port of the traction frame 1, and rotating the rotating ring 210 to screw the screw tube 211 to the port and fix it, while the insert plate 212 is continuously inserted into the frame 101. The insertion of the insert plate 212 and the frame 101 can keep the U-shaped frame plate 2 in a horizontal state. The cable passes through the two push-pull frames 301 and the two rollers 201 in sequence and then enters the traction frame 1 through the screw tube 211. By rotating the adjusting screw 2 305, the door plate 3 is moved. The limiting rod 304 slides at the same time and performs auxiliary fixation to prevent the door plate 3 from shaking as the adjusting screw 2 305 rotates.

[0032] Furthermore, the two door panels 3 move closer to each other, narrowing the width between the two sliding frames 301 until they fit the cable diameter, but are not fully clamped, allowing the cable to still move vertically freely. The two sliding frames 301 adopt an "interlaced sliding connection", that is, the inner flange of one sliding frame 301 is embedded in the groove of the other sliding frame 301. When the door panel 3 is closed, the sliding frames 301 form a narrow rectangular channel, and the cable must move along the axis of this channel. At the same time, the anti-abrasion pad of the sliding frame 301 can be made of materials such as nylon, silicone, and polyurethane elastomer to prevent the cable from rubbing against the sliding frame 301 and protect the cable sheath. If the cable still has a slight displacement due to tension changes, such as expansion or vibration, the elasticity of the tension spring 303 will dynamically adjust the position of the sliding frame 301, making it slide vertically along the door panel 3, "pulling" the cable back to the center and adjusting its position.

[0033] Furthermore, rotating the adjusting screw 209 lifts the upper axle 202 via the connecting plate 207 and connecting rod 208, allowing it to slide upwards along the slot 205. This adjusts the distance between the two rollers 201, accommodating cables of different diameters and maintaining contact between the rollers 201 and the cables. The sliding connection between the rollers 201 and the axle 202 means that the rollers 201 reduce friction through rolling (rotation) and can also slide axially along the axle 202 (similar to curtain track pulleys in the prior art: the pulleys can slide and rotate along the crossbar to accommodate the opening and closing of the curtains).

[0034] Furthermore, when the cable deviates and sways during traction, the roller 201 will rotate around the wheel axle 202, converting the cable's sliding into rolling, and driving the compression spring 204 to rotate together. The compression spring 204 allows the roller 201 to move slightly in the horizontal direction and extend and retract left and right, providing a rebound force through compression or extension, so that the roller 201 always follows and fits the cable, thereby achieving low-friction transmission and resistance to radial deviation.

[0035] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
