Description

Technical Field

[0001] The utility model belongs to the technical field of cable production, and particularly relates to a metal belt stabilizing device and an armoring machine. Background Art

[0002] Armoring machine (stranding machine) is a device used to produce armored cables. It can wrap metal tape (usually steel tape) around the main cable to increase the tensile strength of the final armored cable.

[0003] In related technologies, such as Figure 1 As shown, the armoring machine includes a taping head 200 fixed to a fixed frame 100. A steel tape reel is provided on the taping head 200. The steel tape in the steel tape reel is guided by a guide roller 20 and then delivered to the main cable. When the taping head 200 rotates around the main cable, the steel tape is wound around the main cable, thereby forming an armored cable.

[0004] To allow the armoring machine to use steel strips of varying widths, the guide grooves on the guide rollers 20 are typically set relatively wide. This causes smaller steel strips to easily vibrate in the axial direction of the guide rollers 20 during transport. Furthermore, with the optimization of industry processes, the type of steel strip has gradually shifted from primarily electro-galvanized steel strip to primarily hot-dip steel strip. The production process for hot-dip galvanized steel strip is: cold rolling - online heating - galvanizing - shearing. Compared to the production process for electro-galvanized steel strip, hot-dip galvanized steel strip has the advantage of greater strength. However, hot-dip galvanized steel strip has a brighter surface and lower friction, which further increases the vibration of the steel strip on the guide rollers 20 during transport.

[0005] The jitter of the steel strip on the guide roller 20 causes the angle between the steel strip and the main cable to be unstable. This in turn prevents the steel strip from being wrapped tightly against the main cable, causing slippage. This causes the gap between the steel strip and the main cable to fluctuate significantly, reducing the product's pass rate (a gap ratio of no more than 50% per layer of steel strip is considered pass). Currently, to improve the pass rate, the only solution in the field is to reduce the steel strip winding speed, which affects the production speed of the armoring machine. Utility Model Content

The device further includes a locking assembly comprising at least two screws, one of which passes through the third threaded holes and abuts against the first movable block, and the other passes through the third threaded holes and abuts against the second movable block.

[0011] In some embodiments, the screw is a butterfly screw.

[0025] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0026] Example 1:

[0027] like Figure 2-Figure 6 As shown, an embodiment of the present invention provides a metal belt stabilizing device 300, which is used in an armoring machine to keep the metal belt stable so that the metal belt can be stably wound on the main cable. The metal belt stabilizing device 300 includes a fixing component and a clamping component. The fixing component is fixed to the wrapping head 200 of the armoring machine, and includes a first rotating shaft 7 and a second rotating shaft 8 arranged in parallel. The clamping component includes a first guide wheel 5 and a second guide wheel 9; the first guide wheel 5 is rotatably set on the first rotating shaft 7, and the middle part of the first guide wheel 5 is concave to form a first groove 5-1. The second guide wheel 9 is rotatably set on the second rotating shaft 8, and the middle part of the second guide wheel 9 is concave to form a second groove 9-1. The first groove 5-1 and the second groove 9-1 are arranged opposite to each other, and the two side edges of the metal belt used for cable armoring are respectively in contact with the first groove 5-1 and the second groove 9-1 to confine the metal belt between the first guide wheel 5 and the second guide wheel 9.

[0028] Exemplarily, the fixing assembly is fixed at a position between the metal tape drum and the main cable. The metal tape in the metal tape drum passes through the metal tape stabilizing device 300 and is wound around the main cable.

[0029] Exemplarily, the metal strip used for cable armoring may be a steel strip, and the type of the steel strip may be a hot-dip galvanized steel strip or an electro-galvanized steel strip, etc. In this embodiment, the metal strip is a hot-dip galvanized steel strip.

[0030] The production process of hot-dip galvanized steel strip is: cold rolling - online heating - galvanizing - shearing. The tensile strength of electro-galvanized steel strip is 360N / mm 2 In comparison, the tensile strength of hot-dip galvanized steel strip is increased to 450N / mm 2 , so the tensile strength is higher and the elongation is small.

[0031] Exemplarily, the first guide wheel 5 and the second guide wheel 9 can both be made of metal, which can improve the durability of the first guide wheel 5 and the second guide wheel 9 and avoid frequent replacement.

[0032] After the metal belt is led out from the metal belt reel 21, it enters between the first guide wheel 5 and the second guide wheel 9. The two side edges of the metal belt abut against the first groove 5-1 and the second groove 9-1 respectively. The first groove 5-1 of the first guide wheel 5 and the second groove 9-1 of the second guide wheel 9 simultaneously apply forces in opposite directions to the two side edges of the metal belt, that is, the first groove 5-1 of the first guide wheel 5 and the second groove 9-1 of the second guide wheel 9 simultaneously apply forces toward the center of the metal belt to the two side edges of the metal belt, thereby confining the metal belt to the first groove 5-1 of the first guide wheel 5 -1 and the second groove 9-1 of the second guide wheel 9 prevent the metal belt from jumping during transportation, maintaining a stable relative position and angle between the metal belt and the main cable. This allows the metal belt to be stably wound around the main cable when the wrapping head 200 rotates around the main cable, reducing the phenomenon of the metal belt slipping during the process of wrapping around the main cable and the occurrence of loose contact between the metal belt and the main cable. It also ensures that the gap ratio of each layer of metal belt can be maintained stable, avoiding fluctuations in the outer diameter of the armored cable finally formed, and improving the surface quality and yield rate of the armored cable. On this basis, the winding speed of the metal belt can be increased, thereby increasing the production speed of the armoring machine.

[0033] Furthermore, the first guide wheel 5 and the second guide wheel 9 can also be used to guide the metal strip, so as to replace or partially replace the function of the guide roller 20 in the wrapping head 200 .

[0034] Thus, the metal belt stabilizing device 300 provided by the embodiment of the present invention, by providing mutually parallel first and second rotating shafts 7 and 8 on the fixed assembly, and providing a first guide wheel 5 having a first groove 5-1 on the first rotating shaft 7, and a second guide wheel 9 having a second groove 9-1 on the second rotating shaft 8, can apply opposite forces to the two sides of the metal belt of the cable armor through the first groove 5-1 and the second groove 9-1, respectively, to stabilize the metal belt, thereby maintaining the relative position and relative angle between the metal belt and the main cable, and allowing the wrapping head 200 to stably wrap the metal belt around the main cable, thereby reducing the phenomenon of the metal belt slipping during the process of winding the metal belt around the main cable, reducing the occurrence of the metal belt and the main cable not being tightly attached, and maintaining a stable gap ratio between each layer of metal belt, thereby avoiding fluctuations in the outer diameter of the armored cable and improving the surface quality and yield rate of the armored cable. On this basis, the winding speed of the metal belt can be increased, thereby increasing the production speed of the armoring machine.

[0035] In some embodiments, combined Figure 2-Figure 6 The fixed assembly further includes a fixed block 2, a first movable block 3, and a second movable block 4. The fixed block 2 is fixed to the armouring machine's taping head 200 and has a slide rail C inside. The first movable block 3 is transversely mounted on the slide rail C and slidably connected thereto. The first rotating shaft 7 is fixed to the first movable block 3. The second movable block 4 is transversely mounted on the slide rail C and slidably connected thereto. The second rotating shaft 8 is fixed to the second movable block 4.

[0036] For example, a portion of the first moving block 3 extends into the slide rail C, and a portion of the second moving block 4 extends into the slide rail C. Figure 4 As shown, the portion of the first moving block 3 extending into the slide rail C matches the shape of the slide rail C; similarly, the portion of the second moving block 4 extending into the slide rail C matches the shape of the slide rail C.

[0037] For example, the end of the first rotating shaft 7 has a thread, and the first moving block 3 is provided with a threaded hole adapted to the thread, and the first rotating shaft 7 is fixed to the first moving block 3 via the thread. Similarly, the second rotating shaft 8 is fixed to the second moving block 4 via the thread.

[0038] Alternatively, the first rotating shaft 7 is fixed to the first moving block 3 by welding, and the second rotating shaft 8 is fixed to the second moving block 4 by welding.

[0039] Through the above-mentioned setting, the first moving block 3 and the second moving block 4 can slide on the slide rail C to adjust the distance between the first moving block 3 and the second moving block 4, change the spacing between the first rotating shaft 7 and the second rotating shaft 8, and thus change the spacing between the first groove 5-1 of the first guide wheel 5 and the second groove 9-1 of the second guide wheel 9, so that the first guide wheel 5 and the second guide wheel 9 can be suitable for metal belts of different widths, thereby improving the versatility of the metal belt stabilizing device 300.

[0040] In some embodiments, combined Figure 3-Figure 6 The fixed block 2 has a fixing hole. The first movable block 3 has a first threaded hole at its lower portion, and the second movable block 4 has a second threaded hole at its lower portion. The thread direction of the first threaded hole is opposite to that of the second threaded hole. The fixing assembly further includes a screw 1, which extends in the same direction as the slide rail C. The screw 1 passes through the fixing hole, the first threaded hole, and the second threaded hole, respectively, to connect the fixed block, the first movable block, and the second movable block together.

[0041] The thread direction of the first threaded hole is opposite to that of the second threaded hole. Therefore, when the screw 1 is rotated, the first moving block 3 and the second moving block 4 can be moved in opposite directions in the slide rail C, thereby adjusting the distance between the first moving block 3 and the second moving block 4.

[0042] For example, when the screw is rotated clockwise, the first moving block 3 and the second moving block 4 move away from each other; when the screw is rotated counterclockwise, the first moving block 3 and the second moving block 4 move closer to each other.

[0043] Through the above arrangement, the distance between the first moving block 3 and the second moving block 4 can be flexibly adjusted by the screw, so that the first guide wheel 5 and the second guide wheel 9 can be suitable for metal belts of different widths.

[0044] In some embodiments, as Figure 3 and Figure 5 As shown, the fixed block 2 is further provided with a plurality of third threaded holes, which extend from the outside of the fixed block 2 through the fixed block 2 and to the slide rail C. The metal belt stabilizing device 300 further includes a locking assembly, which includes at least two screws 6. One screw 6 passes through the third threaded hole and abuts against the first movable block 3, and another screw 6 passes through the third threaded hole and abuts against the second movable block 4.

[0045] Exemplarily, the screw 6 is a butterfly screw.

[0046] This makes it easier for the operator to operate the screw 6 with bare hands.

[0047] For example, after adjusting the distance between the first movable block 3 and the second movable block 4 by rotating the screw, a screw 6 can be rotated through the third threaded hole corresponding to the first movable block 3 to abut against the first movable block 3, and a screw 6 can be rotated through the third threaded hole corresponding to the second movable block 4 to abut against the second movable block 4, so as to fix the first movable block 3 and the second movable block 4 by the screw, thereby ensuring that the distance between the first movable block 3 and the second movable block 4 no longer changes, so that the first groove 5-1 of the first guide wheel 5 and the second groove 9-1 of the second guide wheel 9 both abut against the side of the metal belt, thereby stabilizing the metal belt; when it is necessary to adjust the distance between the first movable block 3 and the second movable block 4, the screw 6 can be rotated to leave the first movable block 3 and the second movable block 4, so that the distance between the first movable block 3 and the second movable block 4 can be conveniently adjusted by the screw.

[0048] Through the above-mentioned setting, the stability of the position of the first moving block 3 and the second moving block 4 can be ensured by the screw 6, so that the first groove 5-1 of the first guide wheel 5 and the second groove 9-1 of the second guide wheel 9 can stabilize the metal belt, and facilitate the adjustment of the distance between the first moving block 3 and the second moving block 4, thereby simplifying the adjustment difficulty of the metal belt stabilizing device 300.

[0049] In some embodiments, as Figure 4 As shown, in the cross section of the slide rail C, the size of the bottom of the slide rail C is larger than the size of the top of the slide rail C.

[0050] With the above settings, Figure 4 As shown, the first moving block 3 and the second moving block 4 can be prevented from moving in the vertical direction, thereby ensuring the position stability of the first moving block 3 and the second moving block 4, and then ensuring the stability of the metal belt through the first guide wheel 5 and the second guide wheel 9.

[0051] In some embodiments, as Figure 3 As shown, the number of first guide wheels 5, the number of first rotating shafts 7, the number of second guide wheels 9, and the number of second rotating shafts 8 are all multiple. The first guide wheels 5 are arranged in a one-to-one correspondence with the first rotating shafts 7, and the second guide wheels 9 are arranged in a one-to-one correspondence with the second rotating shafts 8; the first guide wheels 5 and the second guide wheels 9 are arranged in a one-to-one correspondence.

[0052] For example, the number of the first guide wheels 5, the number of the first rotating shafts 7, the number of the second guide wheels 9, and the number of the second rotating shafts 8 are all two or three. Figure 3 As shown, there are two first guide wheels 5, two first rotating shafts 7, two second guide wheels 9, and two second rotating shafts 8. The two corresponding sets of first guide wheels 5 and second guide wheels 9 cooperate to stabilize the metal belt.

[0053] Through the above arrangement, the metal belt can be stabilized by a plurality of correspondingly arranged first guide wheels 5 and second guide wheels 9, so as to further enhance the stabilizing effect of the metal belt stabilizing device 300 on the metal belt.

[0054] Example 2:

[0055] like Figure 2 As shown, an embodiment of the present invention provides an armoring machine for a cable. The armoring machine includes a fixed frame 100, a winding head 200, and the metal belt stabilizing device 300 described in the above-mentioned embodiment 1. The winding head 200 is arranged on the fixed frame 100 and has a hollow main shaft, and the main cable passes through the center of the main shaft; the winding head 200 includes a metal tape reel 21, and the winding head 200 can rotate around its axis to wind the metal tape in the metal tape reel 21 onto the main cable. The metal belt stabilizing device 300 is fixed to the winding head 200 and is used to limit the two side edges of the metal belt between the first groove 5-1 of the first guide wheel 5 and the second groove 9-1 of the second guide wheel 9. After passing through the metal belt stabilizing device 300, the metal belt is wound onto the main cable.

[0056] Exemplarily, the fixing frame 100 is used to support the taping head 200 .

[0057] Illustratively, a driving component is provided on the fixing frame 100 to drive the wrapping head 200 to rotate around the axis of its main axis.

[0058] Exemplarily, the main cable passes through the center of the main shaft under the traction of the traction mechanism.

[0059] Exemplarily, the metal belt reel 21 and the metal belt stabilizing device 300 may also be provided with guide rollers 20 to assist in guiding the metal belt.

[0060] The above-described arrangement enables the armoring machine to stably wrap the metal tape around the main cable, reducing the risk of slippage and loose contact between the metal tape and the main cable. This maintains a stable gap between each layer of metal tape, preventing fluctuations in the outer diameter of the armored cable and improving the yield rate. Furthermore, the speed at which the metal tape is wound around the main cable can be increased, thereby increasing the production speed of the armoring machine.

[0061] In some embodiments, as Figure 2 As shown, there are two metal belt reels 21 , which are respectively arranged on both sides of the main shaft and opposite to each other. There are two metal belt stabilizing devices 300 , each of which is respectively arranged corresponding to one metal belt reel 21 .

[0062] Through the above arrangement, two metal tapes can be simultaneously drawn out from the two metal tape reels 21, and the two metal tapes are successively wound on the main cable, wherein one metal tape is first wound on the main cable, and the other metal tape can cover the gap of the other metal tape, so that the metal tape completely covers the main cable, thereby completing the covering of the main cable in one winding process, improving the efficiency of winding the metal tape on the cable, and improving the production efficiency of the finally formed armored cable.

[0063] In some embodiments, as Figure 2 As shown, the angle between the metal belt and the main cable after passing through the metal belt stabilizing device 300 ranges from 40° to 70°.

[0064] like Figure 2 As shown, the angle between the metal belt and the cable after passing through the metal belt stabilizing device 300 is Figure 2 α in .

[0065] The value of α can be 40°, 45°, 50°, 60° or 70°, etc.

[0066] Through the above-mentioned arrangement, the angle between the metal belt after passing through the metal belt stabilizing device 300 and the main cable can be maintained within an appropriate range. The metal belt is wound around the main cable at the above-mentioned angle during rotation, so that the metal belt forms a regular wrapping pitch on the main cable. The gap and coverage between the metal belts can be controlled relatively easily, thereby improving the winding quality of the metal belt and ultimately improving the quality and pass rate of the armored cable.

[0067] It is understood that the above embodiments are merely exemplary embodiments for illustrating the principles of the present invention, and the present invention is not limited thereto. Those skilled in the art may make various modifications and improvements without departing from the spirit and substance of the present invention, and such modifications and improvements are also considered to be within the scope of protection of the present invention.
