Description

Technical Field

[0001] This invention relates to the field of cable manufacturing technology, and in particular to an automatic bonding device for water-blocking tape on submarine cables. Background Technology

[0002] During the manufacturing process of submarine cables, water-blocking tape needs to be attached to the outside of the cable conductor. The traditional method of attaching water-blocking tape is to use a wrapping machine to drive the water-blocking tape to wrap and attach to the surface of the cable conductor.

[0003] In actual use, the water-blocking tape is fixed on the winding bracket of the wrapping machine. Then the cable conductor passes through the middle of the wrapping machine. Then the transmission structure drives the water-blocking tape on the winding bracket to rotate, so that the water-blocking tape can be wrapped around the cable conductor 6, realizing the automatic wrapping and bonding of the water-blocking tape and the cable conductor.

[0004] However, while this type of cable water-blocking tape bonding equipment can indeed achieve automatic wrapping and bonding of the water-blocking tape and cable conductor in actual use, it still has some shortcomings in practical application, such as:

[0005] In practical use, existing cable wrapping machines often expose the water-blocking tape's wrapping bracket to the outside in order to allow workers to intuitively understand the cable wrapping situation and facilitate the replacement of the water-blocking tape. This makes the water-blocking tape susceptible to interference from external airflow during the wrapping process. When external airflow blows the released water-blocking tape, the tension of the water-blocking tape is also affected by the external airflow. At this time, the rolled water-blocking tape will release more water-blocking tape, resulting in unstable tension of the rolled water-blocking tape during release, which affects the water-blocking tape's wrapping and adhesion to the cable conductor. Summary of the Invention

[0006] In view of the shortcomings of the prior art, the purpose of this invention is to provide an automatic bonding device for submarine cable water-blocking tape, which can solve the technical problem that the tension of the water-blocking tape is interfered with by the external airflow, which leads to unstable tension of the rolled water-blocking tape when it is released, affecting the bonding of the water-blocking tape to the cable conductor.

[0007] In a first aspect, an automatic bonding device for water-blocking tape on submarine cables is provided, comprising: a shell structure, an extrusion structure detachably connected inside the shell structure, a traction structure rotatably mounted on the extrusion structure, and a transmission structure disposed on the extrusion structure near the traction structure.

[0008] The traction structure includes a rotating ring and a swing arm distributed at the rear of the rotating ring. The lower part of the swing arm is fixedly connected to a rotating rod, a first pressing strip and a second pressing strip. The rotating rod and the rotating ring are rotatably connected. A plug-in post is fixedly connected to the part of the swing arm away from the rotating rod.

[0009] The rotating ring is fixed with a mounting plate on the side opposite to the swing arm. Support frames are fixedly connected to both mounting plates. A connecting rod slides between the two support frames. An insert rod is fixedly connected to the connecting rod. The insert rod is inserted into the mounting plate and the rotating ring. A sleeve spring is sleeved on the part of the mounting plate opposite to the connecting rod. A connecting piece is fixed on the part of the insert rod near the sleeve spring. The sleeve spring is fixed between the connecting piece and the mounting plate.

[0010] A pulling structure is connected to the swing arm. When the pulling structure drives the first and second pressing bars to press against the insertion rod, the abutment rod slides on the support frame.

[0011] In a second aspect of the present invention, an automatic bonding device for water-blocking tape of submarine cables is provided, comprising: the first pressure strip and the second pressure strip have the same structure, and the first pressure strip and the second pressure strip are distributed opposite to each other, and both the first pressure strip and the second pressure strip are provided with extrusion grooves.

[0012] The insertion rod includes a sliding head integrally fixed on the insertion rod. The sliding head is fixedly connected to the end of the insertion rod away from the abutment rod, and the sliding head slides inside the extrusion groove.

[0013] The shell structure includes a bottom shell, a rotating shell, and a protective shell. The rotating shell is rotatably connected to the bottom shell, and the protective shell is snapped onto the rotating shell.

[0014] The extrusion structure includes an eddy current sensor, an extrusion tube, a rotating channel, and a connecting seat;

[0015] The connecting seat is fixedly connected to the bottom wall of the inner cavity of the bottom shell. The extrusion tube and the eddy current sensor are fixedly connected to the connecting seat. The rotating channel is opened on the connecting seat near the extrusion tube. A cable conductor passes through the connecting seat. The cable conductor passes through the extrusion tube, the rotating shell, the bottom shell, and the protective shell. A detection block is fixedly connected to the rotating ring near the eddy current sensor. A controller and a buzzer are connected to the rotating shell.

[0016] The transmission structure includes a transmission motor, transmission gears, a rotating sleeve, and a rotating gear ring;

[0017] The drive motor is detachably connected to the connecting seat. The output shaft of the drive motor is fixedly connected to a drive gear. A rotating gear ring meshes with the drive gear. A rotating sleeve is fixedly connected to the rotating gear ring. The rotating sleeve and the rotating ring are inserted and fixed.

[0018] The end of the rotating sleeve near the connecting seat is inserted into the interior of the rotating channel. The rotating toothed ring does not contact the connecting seat, the first pressing strip, or the second pressing strip. There is a gap between the rotating toothed ring and the rotating ring.

[0019] The pulling structure includes a pulling rod, a sliding sleeve, a screw, a rotating ring, and a rotating handle;

[0020] The screw is inserted between the rotating gear ring and the rotating ring. One end of the screw is fixedly connected to the rotating sleeve. The rotating handle, the rotating ring and the sliding sleeve are sequentially sleeved on the screw. The rotating ring and the rotating handle are fixedly connected. The rotating ring and the sliding sleeve are rotatably connected. The pulling rod and the sliding sleeve are rotatably connected.

[0021] A bent rod is fixedly connected between the other end of the screw and the rotating sleeve. A rotating seat is rotatably connected to the end of the pulling rod away from the sliding sleeve. The rotating seat is fixedly connected to the swing arm.

[0022] A rolled water-blocking tape is sleeved on the plug post. The water-blocking tape released from the rolled water-blocking tape abuts against the abutting rod, which has a columnar structure.

[0023] The beneficial effects of the technical solutions provided by the embodiments of the present invention include at least the following:

[0024] In this embodiment of the invention, the housing structure can accommodate the released water-blocking tape, facilitating its secure winding around the cable conductor and preventing direct contact between external airflow and the tape. This ensures the tape remains stably wound around the conductor, preventing instability in its application. The rotating handle moves on the screw. When the handle moves, the sliding sleeve can pull the lever to swing the swing arm on the rotating ring. The sliding head can then move inside the extrusion groove, adjusting the position of the insertion rod and the abutment rod. This allows the abutment rod to control the tension of the water-blocking tape, preventing instability in its application when airflow changes within the housing structure. As the sliding sleeve pulls the lever to swing the swing arm on the rotating ring, the arm gradually approaches the opening of the rotating housing. The operator can then open the inner cavity of the bottom housing through the rotating housing to replace the rolled water-blocking tape on the arm. Attached Figure Description

Detailed Implementation

[0035] To enable those skilled in the art to better understand the technical solutions in the embodiments of the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0036] Furthermore, descriptions of well-known structures and techniques are omitted in the following description to avoid unnecessarily obscuring the concepts disclosed in this invention.

[0037] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention.

[0038] Reference manual attached Figure 1-8 The present invention illustrates an automatic bonding device for water-blocking tape of submarine cables, comprising: a housing structure 1, an extrusion structure 2 detachably connected inside the housing structure 1, a traction structure rotating on the extrusion structure 2, and a transmission structure provided on the extrusion structure 2 near the traction structure.

[0039] The traction structure includes a rotating ring 3 and a swing arm 4 distributed at the rear of the rotating ring 3. The lower part of the swing arm 4 is fixedly connected to a rotating rod 44, a first pressing strip 41 and a second pressing strip 46. The rotating rod 44 and the rotating ring 3 are rotatably connected. The part of the swing arm 4 away from the rotating rod 44 is fixedly connected to a plug post 42.

[0040] A mounting plate 73 is fixedly attached to the side of the rotating ring 3 opposite to the swing arm 4. Support brackets 7 are fixedly connected to both mounting plates 73. A contact rod 71 slides between the two support brackets 7. An insertion rod 72 is fixedly connected to the contact rod 71. The insertion rod 72 is inserted into the mounting plate 73 and the rotating ring 3. A sleeve spring 74 is sleeved on the part of the mounting plate 73 opposite to the contact rod 71. A connecting piece 75 is fixed on the part of the insertion rod 72 near the sleeve spring 74. The sleeve spring 74 is fixed between the connecting piece 75 and the mounting plate 73.

[0041] A pulling structure 8 is connected to the swing arm 4. When the pulling structure 8 drives the first pressing bar 41 and the second pressing bar 46 to press the insertion rod 72, the abutment rod 71 slides on the support frame 7.

[0042] The beneficial effects of the technical solutions provided by the embodiments of the present invention include at least the following:

[0043] In actual use, the extrusion structure 2 can support the cable conductor 6 to be processed. At the same time, the cable conductor 6 can extend through the shell structure 1 to the outside. The operator puts the rolled water-blocking tape 9 onto the plug post 42, and then the water-blocking tape released from the rolled water-blocking tape 9 abuts against the abutting rod 71. The water-blocking tape released from the rolled water-blocking tape 9 is fixed on the cable conductor 6. During this process, the transmission structure can drive the rotating ring 3 to rotate. At this time, the rotating ring 3 can drive the rolled water-blocking tape 9 to rotate through the swing arm 4. As the cable conductor 6 passes through and moves from the extrusion structure 2 and the shell structure 1, the swing arm 4 can drive the water-blocking tape to wrap around the cable conductor 6. Since the work of wrapping the water-blocking tape around the cable conductor 6 is carried out inside the shell structure 1, and the abutting rod 71 can also abut against the water-blocking tape, the water-blocking tape can provide strong tension during the wrapping process, and the water-blocking tape can be stably wrapped around the cable conductor 6.

[0044] In one possible implementation, the first pressing strip 41 and the second pressing strip 46 have the same structure, and the first pressing strip 41 and the second pressing strip 46 are distributed opposite to each other, and both the first pressing strip 41 and the second pressing strip 46 are provided with extrusion grooves 45.

[0045] In this embodiment of the invention, the rotating rod 44 is located on the swing arm 4 near the first pressing strip 41 and the second pressing strip 46. The pulling structure 8 can drive the swing arm 4 to rotate around the rotating rod 44, which makes it convenient for workers to replace the rolled water-blocking strip 9 on the plug-in post 42.

[0046] In one possible implementation, the insertion rod 72 includes a sliding head 76 integrally fixed to the insertion rod 72. The sliding head 76 is fixedly connected to the end of the insertion rod 72 away from the abutment rod 71, and slides inside the compression groove 45.

[0047] In this embodiment of the invention, the repulsive force generated by the sleeve spring 74 can drive the sliding head 76 to stably abut against the inside of the extrusion groove 45. The bottom wall of the inner cavity of the extrusion groove 45 is an inclined slope structure. When the worker needs to replace the roll water-blocking tape 9, the pulling structure 8 can drive the swing arm 4 to rotate. At this time, the sliding head 76 moves to the lower part of the inner cavity of the extrusion groove 45, thereby reducing the abutment force of the abutment rod 71 against the water-blocking tape.

[0048] In one possible implementation, the housing structure 1 includes a bottom shell 12, a rotating shell 11, and a protective shell 13, with the rotating shell 11 rotatably connected to the bottom shell 12 and the protective shell 13 snapped onto the rotating shell 11.

[0049] In this embodiment of the invention, the bottom shell 12, the rotating shell 11 and the protective shell 13 can form a cover shell for the rolled water-blocking tape 9, which can ensure that when the rolled water-blocking tape 9 is wrapped around the cable conductor 6, the external airflow cannot come into contact with the water-blocking tape wrapped around the cable conductor 6.

[0050] In one possible implementation, the extrusion structure 2 includes an eddy current sensor 21, an extrusion tube 22, a rotating channel 23, and a connecting seat 25.

[0051] The connecting seat 25 is fixedly connected to the bottom wall of the inner cavity of the bottom shell 12. The extrusion tube 22 and the eddy current sensor 21 are fixedly connected to the connecting seat 25. The rotating channel 23 is opened on the connecting seat 25 near the extrusion tube 22. The cable conductor 6 passes through the connecting seat 25. At the same time, the cable conductor 6 passes through the extrusion tube 22, the rotating shell 11, the bottom shell 12 and the protective shell 13. The rotating ring 3 is fixedly connected to the detection block 32 near the eddy current sensor 21. The controller 10 and the buzzer 101 are connected to the rotating shell 11.

[0052] In this embodiment of the invention, the rotating ring 3 is made of a material that does not generate eddy current effect, and the detection block 32 is made of a metal material that can generate eddy current effect. At the same time, there is only one detection block 32. When the staff needs to replace the roll-shaped water-blocking tape 9, the staff controls the eddy current sensor 21 to work through the controller 10. When the eddy current sensor 21 detects that the detection block 32 and the detection end of the eddy current sensor 21 are opposite each other, the signal end of the eddy current sensor 21 will send a signal to the controller 10. At this time, the controller 10 controls the transmission motor 5 to stop working. Then, the pulling structure 8 can drive the swing arm 4 to rotate, which makes it convenient for the staff to replace the roll-shaped water-blocking tape 9.

[0053] When the connector 25 is in use, the operator passes the cable conductor 6 through the extrusion tube 22, the rotating shell 11, the bottom shell 12 and the protective shell 13. At this time, the extrusion tube 22 can extrude the material of the cable conductor 6, so that the water-blocking tape 9 can be released and wrapped around the cable conductor 6.

[0054] In one possible implementation, the transmission structure includes a transmission motor 5, a transmission gear 24, a rotating sleeve 33, and a rotating gear ring 31.

[0055] The drive motor 5 is detachably connected to the connecting seat 25. The output shaft of the drive motor 5 is fixedly connected to the drive gear 24. A rotating gear ring 31 meshes with the drive gear 24. A rotating sleeve 33 is fixedly connected to the rotating gear ring 31. The rotating sleeve 33 and the rotating ring 3 are inserted and fixed.

[0056] In this embodiment of the invention, when the output end of the transmission motor 5 drives the rotating gear ring 31 on the rotating sleeve 33 to rotate through the transmission gear 24, the rotating sleeve 33 can drive the rolled water-blocking tape 9 on the swing arm 4 to rotate through the rotating ring 3, thereby realizing that the water-blocking tape released by the rolled water-blocking tape 9 is wrapped around the cable conductor 6.

[0057] In one possible implementation, the end of the rotating sleeve 33 near the connecting seat 25 is inserted into the interior of the rotating channel 23, and the rotating toothed ring 31 does not contact the connecting seat 25, the first pressing strip 41 and the second pressing strip 46, and there is a gap between the rotating toothed ring 31 and the rotating ring 3.

[0058] In this embodiment of the invention, when the output end of the transmission motor 5 drives the rotating gear ring 31 on the rotating sleeve 33 to rotate through the transmission gear 24, the rotating sleeve 33 can rotate inside the rotating channel 23.

[0059] In one possible implementation, the pull structure 8 includes a pull rod 81, a sliding sleeve 82, a screw 83, a rotating ring 84, and a rotating handle 85.

[0060] The screw 83 is inserted between the rotating gear ring 31 and the rotating ring 3. One end of the screw 83 is fixedly connected to the rotating sleeve 33. The rotating handle 85, the rotating ring 84 and the sliding sleeve 82 are sequentially sleeved on the screw 83. The rotating ring 84 and the rotating handle 85 are fixedly connected. The rotating ring 84 and the sliding sleeve 82 are rotatably connected. The pulling rod 81 and the sliding sleeve 82 are rotatably connected.

[0061] In this embodiment of the invention, when the operator rotates the rotating handle 85, the sliding sleeve 82 can pull the swing arm 4 through the pulling rod 81. At this time, the swing arm 4 will gradually approach the opening of the rotating shell 11, which makes it easier for the operator to replace the roll-shaped water-blocking belt 9.

[0062] In one possible implementation, a bent rod 86 is fixedly connected between the other end of the screw 83 and the rotating sleeve 33, and a rotating seat 43 is rotatably connected to the end of the pulling rod 81 away from the sliding sleeve 82. The rotating seat 43 and the swing arm 4 are fixedly connected.

[0063] In this embodiment of the invention, the bent rod 86 can stably support the screw 83, which can prevent the screw 83 from being unstablely connected to the rotating sleeve 33. This allows the sliding sleeve 82 to pull the swing arm 4 through the pulling rod 81, so that the swing arm 4 will gradually approach the opening of the rotating shell 11.

[0064] In one possible implementation, a rolled water-blocking tape 9 is sleeved on the plug post 42, and the water-blocking tape 9 released from the rolled water-blocking tape 9 abuts against the abutting rod 71, which has a columnar structure.

[0065] In this embodiment of the invention, when the water-blocking tape released by the rolled water-blocking tape 9 comes into contact with the abutting rod 71, the abutting rod 71 can firmly abut against the water-blocking tape released by the rolled water-blocking tape 9 under the elastic repulsive force of the sleeve spring 74. This can prevent the water-blocking tape released by the rolled water-blocking tape 9 from being easily moved by the airflow inside the housing structure 1 when the water-blocking tape is wrapped around the cable conductor 6, and realize that the water-blocking tape released by the rolled water-blocking tape 9 is stably wrapped around the cable conductor 6.

[0066] Working principle: In actual use, the operator controls the eddy current sensor 21 through the controller 10. When the eddy current sensor 21 detects that the detection block 32 and the detection end of the eddy current sensor 21 are opposite each other, the signal end of the eddy current sensor 21 will send a signal to the controller 10. At this time, the controller 10 controls the drive motor 5 to stop working. Then the operator flips the rotating shell 11 on the bottom shell 12, and the swing arm 4 will be exposed from the inner cavity of the rotating shell 11. When the operator needs to replace the roll water-blocking tape 9, the operator rotates the rotating handle 85. The sliding sleeve 82 can pull the swing arm 4 through the pull rod 81. At this time, the swing arm 4 will gradually approach the opening of the rotating shell 11. During this process, the pulling structure 8 can drive the swing arm 4 to rotate. At this time, the sliding head 76 moves to the lower part of the inner cavity of the extrusion groove 45, thereby reducing the contact force of the abutment rod 71 on the water-blocking tape, making it easier for the operator to replace the roll water-blocking tape 9.

[0067] After the staff replaces the roll water-blocking tape 9, they fix the winding end of the roll water-blocking tape 9 and the cable conductor 6, and then rotate the handle 85 in the opposite direction. The sliding sleeve 82 can push the swing arm 4 through the pull rod 81. At this time, the swing arm 4 will gradually move away from the opening of the rotating shell 11, and the sliding head 76 will move to the higher part of the inner cavity of the extrusion groove 45, thereby increasing the abutment force of the abutment rod 71 on the water-blocking tape. Then the staff will fasten the rotating shell 11 onto the bottom shell 12, and then the staff can control the transmission motor 5 to work through the controller 10.
