Description

Technical Field

[0001] This utility model belongs to the field of waterproof cable technology, specifically relating to a heat-bonding device for waterproof cable wrapping tape. Background Technology

[0002] The thermal bonding of waterproof cable wrapping tape is a key process in cable protection manufacturing. Its core principle is to controllably heat the waterproof wrapping tape's molten layer or substrate to a viscous state, then apply external pressure to achieve a tight bond between the tape and the cable. After cooling, a continuous, gapless seal is formed. In actual processing, the uniformity of the bonding pressure directly affects the degree of molecular-level bonding between the tape and the cable surface, and is one of the key factors ensuring waterproof sealing and structural stability.

[0003] A search revealed a cable wrapping heat bonding device with publication number CN222965876U, comprising a bottom shell, a top shell, a cable body, and a composite flame-retardant wrapping tape covering the outer surface of the cable body. The top shell is hinged to the bottom shell. Both the inlet and outlet ends of the bottom shell are equipped with support rollers. Two symmetrical heating chambers are arranged inside the bottom shell, and several circulating fans are arranged on the top shell. The hot air heating mechanism, consisting of circulating fans and heating chambers, can heat the cable outer sheath material to a slightly molten state. Then, the halogen-free, low-smoke composite flame-retardant wrapping tape is tightly pressed to the cable outer sheath by clamping rollers and holding rollers, thereby completing the cable wrapping heat bonding process.

[0004] Existing heat bonding equipment requires the cable to be transported to the equipment for heat bonding, and the equipment cannot directly perform heat bonding operations on the laid cable at the construction site. Utility Model Content

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0025] Reference Figures 1-6 A heat-bonding device for waterproof cable wrapping tape, comprising: A first mounting bracket 100 and a second mounting bracket 200 are symmetrically arranged and enclosed to form an annular channel for accommodating cables. One end of the first mounting bracket 100 and the second mounting bracket 200 are rotatably connected by a hinge, and the other end is detachably connected by a snap-fit ​​structure. The fitting seat 300 is movably disposed within the annular channel, and the moving trajectory of the fitting seat 300 is adapted to the circumferential direction of the annular channel. The driving mechanism is located in the annular channel and is used to drive the bonding seat 300 to move circumferentially along the annular channel. The bonding roller 302 is rotatably mounted on the side of the bonding seat 300 facing the center of the annular channel. The bonding roller 302 is used to press against the wrapping tape wrapped around the surface of the cable during the movement of the bonding seat 300 to achieve bonding.

[0026] The symmetrical arrangement and opening / closing structure of the first mounting bracket 100 and the second mounting bracket 200 ensure that the device can stably enclose the cable and facilitate loading and unloading. The moving trajectory of the bonding seat 300 is adapted to the circumference of the annular channel, allowing it to carry the bonding roller 302 along the outer circumference of the cable, ensuring that the pressing path matches the wrapping direction of the tape and achieving full circumferential coverage. The drive mechanism provides circumferential moving power to the bonding seat 300, replacing manual pushing and ensuring uniform and stable moving speed, avoiding the bonding effect caused by speed fluctuations. The bonding roller 302 can be rotatably mounted on the side of the bonding seat 300 facing the center of the channel, so that it can roll synchronously with the bonding seat 300 when pressing the tape, converting sliding friction into rolling friction and reducing damage to the tape. At the same time, through the positional design of the bonding seat 300 and the bonding roller 302, the bonding roller 302 always maintains effective pressure on the tape.

[0027] In one embodiment, the driving mechanism includes: two connecting plates 400, which are respectively mounted on the first mounting bracket 100 and the second mounting bracket 200, the two connecting plates 400 are symmetrically arranged and enclose to form a track for moving the bonding seat 300; and a movable seat 401, which is mounted on the side of the bonding seat 300 away from the bonding roller 302, and both connecting plates 400 are provided with a movable groove, the movable seat 401 being disposed in the movable groove.

[0028] Specifically, based on the circumferential structure of the annular channel, two connecting plates 400 are respectively installed and symmetrically enclosed with the first mounting frame 100 and the second mounting frame 200, so that the formed track is concentric with the annular channel and the curvature is adapted, ensuring that the movement trajectory of the bonding seat 300 is completely matched with the outer circumference of the cable, providing a path foundation for the bonding roller 302 to press evenly in the circumference; the moving seat 401, as the connecting component between the bonding seat 300 and the track, is embedded in the moving groove. Through the radial constraint of the groove on the moving seat 401, the bonding seat 300 is limited to moving only in the circumferential direction of the track, avoiding radial offset during the pressing process. At the same time, by utilizing the fixed relationship between the connecting plate 400 and the mounting frame, the track moves synchronously with the opening and closing of the mounting frame, ensuring that the track can be smoothly separated when the device loads and unloads the cable, and can be accurately closed to form a complete guide structure during operation, realizing the coordination of the guiding function and the opening and closing function of the device.

[0029] In one embodiment, the movable seat 401 includes: a power source 402, a groove is provided on one side of the movable seat 401, and the power source 402 is installed in the groove; a gear 403 is installed on the power shaft of the power source 402, and a rack 404 is installed on the inner wall of the movable groove, and the gear 403 meshes with the rack 404; the rack 404 is arc-shaped, and the arc of the rack 404 is consistent with the circumferential arc of the annular channel.

[0030] Specifically, the power source 402 uses a servo motor, or a stepper motor, to generate rotational motion. This rotational motion is converted into linear motion of the bonding seat 300 along an arc-shaped track through the meshing of gear 403 and rack 404. This ensures that the moving speed of the bonding seat 300 is stable and controllable, providing a power basis for evenly pressing the wrapping tape. The arc-shaped design of the rack 404 matches the circumference of the annular channel to ensure that the trajectory of the rack 404 perfectly matches the required moving trajectory of the bonding seat 300. This ensures that the gear 403 remains effectively meshed with the rack 404 as it moves with the bonding seat 300, preventing tooth slippage or jamming. Installing the power source 402 in the groove of the moving seat 401 is a spatial optimization achieved through integrated structural design. This protects the power source 402 from external environmental interference and makes the connection between the power output shaft and gear 403 more direct.

[0031] In one embodiment, the bonding seat 300 includes: an adjustment groove formed on one side of the bonding seat 300; a movable seat 301 installed in the adjustment groove, and the bonding roller 302 rotatably installed at the end of the movable seat 301 away from the bonding seat 300; and an elastic member 303 installed between the inner wall of the adjustment groove and the movable seat 301.

[0032] Specifically, based on the force compensation mechanism of elastic deformation, the elastic element 303 can be a spring or an elastic block. The pre-compression state of the elastic element 303 can provide a continuous pre-tightening force for the movable seat 301, so that the bonding roller 302 always has the basic pressure to press against the wrapping tape. When the cable diameter increases or the wrapping tape is locally thicker, the bonding roller 302 is subjected to a reverse force, which pushes the movable seat 301 to move into the adjustment groove and compress the elastic element 303. The elastic force of the elastic element 303 increases with the increase of the compression amount, forming a pressure that balances with the external resistance. When the cable diameter decreases or the wrapping tape is locally thinner, the elastic force of the elastic element 303 is released, which pushes the movable seat 301 to drive the bonding roller 302 to move closer to the cable, maintaining effective pressure. The adjustment groove, through the guiding constraint of the movable seat 301, ensures that its movement direction is always radial along the bonding seat 300 pointing to the center of the cable, ensuring that the pressure direction is accurately applied to the surface of the wrapping tape, and finally achieving adaptive and uniform pressing of the wrapping tape under different working conditions.

[0033] In a preferred embodiment, both the first mounting bracket 100 and the second mounting bracket 200 have cavities 101 inside. Each cavity 101 has a plurality of air holes 102 on the side facing the annular channel. The air holes 102 are arranged in an array along the circumference of the annular channel, and the axis of the air holes 102 points to the center of the annular channel. Both the first mounting bracket 100 and the second mounting bracket 200 are equipped with hot air blowers 103, and the air outlet pipes of the two hot air blowers 103 are respectively connected to the two cavities 101.

[0034] Specifically, the cavity 101 serves as a hot air buffer and distribution chamber, allowing the airflow input from the hot air blower 103 to be fully mixed inside, avoiding local airflow speed or temperature fluctuations. The air blowing holes 102 are distributed in a circumferential array along the annular channel and point towards the center. Their position and angle design match the circular contour of the cable, ensuring that the hot air acts evenly on the surface of the strapping from multiple directions, forming a surrounding heating area to meet the heating requirements of the entire circumference of the strapping. The connection method between the hot air blower 103 and the cavity 101 ensures efficient hot air delivery, reduces heat loss, and allows the strapping to be pressed by the bonding roller 302 immediately after being heated and softened, utilizing the fluidity of the material in a viscous state to achieve a tighter bond.

[0035] In one embodiment, the snap-fit ​​structure includes two mating lugs, which are respectively fixed to the free ends of the first mounting bracket 100 and the second mounting bracket 200. The two mating lugs are provided with coaxial connecting holes, and bolts are inserted into the connecting holes and locked in place by nuts.

[0036] By using the coaxial connection hole and the locking of the bolt and nut, a stable and adjustable locking force can be provided to the free end of the mounting bracket, ensuring that a complete annular channel is formed after the first mounting bracket 100 and the second mounting bracket 200 are closed. The threaded connection of the bolt and nut is simple to operate and facilitates quick disassembly and locking. Combined with the rotation function of the hinge, the device can be opened and closed flexibly to accommodate the insertion and removal of cables of different diameters.

[0037] In one embodiment, the outer peripheral wall of the bonding roller 302 is wrapped with a silicone layer, and the surface of the silicone layer is provided with anti-slip textures distributed circumferentially.

[0038] In the above technical solution, the silicone layer on the outer periphery of the bonding roller 302 has good elasticity and high temperature resistance. When pressing the wrapping tape, it can closely adapt to the curvature of the cable surface and the slight undulations of the wrapping tape through its own deformation, so that the pressing pressure is transmitted to the surface of the wrapping tape more evenly, avoiding local pressure concentration or wrapping tape damage caused by rigid contact. At the same time, the high temperature resistance of the silicone layer can adapt to the ambient temperature during heat bonding, and it is not easy to age or deform due to heat, ensuring long-term stability. The anti-slip texture distributed along the circumference of the surface can increase the friction between the bonding roller 302 and the wrapping tape, preventing relative sliding between the bonding roller 302 and the wrapping tape when rolling.

[0039] During use, the first mounting bracket 100 and the second mounting bracket 200 are rotated and separated around the hinge. The cable wrapped with waterproof tape is placed into the annular channel and its position is adjusted so that the tape wrapping area corresponds to the bonding roller 302 and the air blowing hole 102. Then, the two mounting brackets are closed so that the connecting holes of the mating ear plates are coaxially aligned. Bolts are inserted and nuts are tightened to ensure that the annular channel is completely closed and the cable is fixed stably without radial displacement. Next, the hot air blower 103 on the first mounting bracket 100 and the second mounting bracket 200 is started. The hot air flows into the cavity 101 inside the mounting bracket through the air outlet pipe. After being fully mixed in the cavity 101, it forms a 360° surrounding hot air jet through the air blowing holes 102 that are distributed circumferentially along the annular channel and point to the center. This uniformly heats the waterproof tape on the surface of the cable to a viscous state. Then, the power source 402 of the drive mechanism is started. The output shaft of the power source 402 drives the gear 403 to rotate. Because the gear 403 and the arc-shaped rack on the inner wall of the moving groove are connected, the cable is heated to a viscous state. 404 engages, driving the movable seat 401 to slide along the moving groove of the connecting plate 400, thereby driving the bonding seat 300 to move circumferentially along the annular channel. During the movement of the bonding seat 300, the bonding roller 302 rotates synchronously due to contact with the surface of the wrapping tape. The silicone layer adapts to the curvature of the cable surface and the thickness undulation of the wrapping tape through elastic deformation and evenly transmits the pressing pressure. The anti-slip texture prevents the bonding roller 302 from sliding relative to the wrapping tape. If there is a slight deviation in the cable diameter or the wrapping tape is locally too thick, the movable seat 301 moves along the adjusting groove of the bonding seat 300, compressing or releasing the elastic element 303 to maintain stable pressure through elastic force compensation, ensuring that the wrapping tape and the cable surface are bonded without gaps. After the bonding seat 300 drives the bonding roller 302 to complete at least one revolution along the annular channel, first turn off the hot air blower 103 and continue to keep the drive mechanism running for 1-2 revolutions to use residual heat to assist in the shaping of the wrapping tape. Then turn off the power source 402, and finally loosen the bolts of the buckle structure, separate the mounting bracket and take out the cable.
