Description

Technical Field

[0001] The present invention relates to the technical field of pipe stranding machines, and particularly to a cable pipe stranding machine. Background Art

[0002] A cable pipe stranding machine is a mechanical device used in cable manufacturing. It is mainly used to twist multiple cable core wires together in a specific manner to form the core structure of the cable. Through precise rotation and traction systems, the machine twists the wires into a cable with a specified pitch and lay direction, ensuring the strength, flexibility, and electrical performance of the cable. Cable pipe stranding machines are widely used in fields such as electricity, communication, and construction, and are key equipment indispensable in the cable production process.

[0003] Existing cable pipe stranding machines mainly include a core wire storage bin, a wire pay-off stand, a stranding mechanism, a traction mechanism, and a take-up mechanism. The wire pay-off stand is arranged inside the core wire storage bin and is used to install the spools of multiple cable core wires and release the cable core wires. The existing wire pay-off stand is fixedly arranged relative to the storage bin and is hidden inside the storage bin. An installation opening is provided on the storage bin to allow the spool to pass through for replacement. However, this layout causes the spool to be replaced only inside the storage bin, and the space reserved inside the storage bin for replacing the spool is limited, restricting the replacement operation space, increasing the difficulty and time of replacement. In addition, operating to replace the spool in a narrow space increases the safety risk for operators and may lead to operation errors or injuries. Summary of the Invention

[0004] The purpose of the present invention is to provide a cable pipe stranding machine that is convenient for replacing the spool to solve the technical problems raised in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solutions.

[0006] A cable pipe stranding machine includes a pot-shaped wire pay-off bin, a driving main shaft, and a spool mounting rack. The pot-shaped wire pay-off bin has a circular cross-section and extends horizontally. One end of the pot-shaped wire pay-off bin is provided with a shaft mounting rack. The driving main shaft is rotatably mounted on the shaft mounting rack and is coaxial with the pot-shaped wire pay-off bin. One end of the driving main shaft extends into the pot-shaped wire pay-off bin, and the other end extends outside the pot-shaped wire pay-off bin. A second driving mechanism is provided at the end of the driving main shaft located inside the pot-shaped wire pay-off bin. A plurality of spool mounting racks are arranged in a circular array around the axis of the pot-shaped wire pay-off bin through the second driving mechanism. The second driving mechanism is used to drive each spool mounting rack to feed and retract along the corresponding radial direction of the pot-shaped wire pay-off bin. The outer peripheral wall of the pot-shaped wire pay-off bin is evenly arranged in an array around its axis with access openings for the spool mounting racks to pass through. The number of access openings is the same as that of the spool mounting racks. When the second driving mechanism drives each spool mounting rack to feed to the limit position, each spool mounting rack can pass through the corresponding access opening and extend outside the pot-shaped wire pay-off bin.

[0007] After the cable core wire on the coil cylinder is used up, the second driving mechanism works to drive each coil cylinder mounting bracket to feed towards the periphery of the can-shaped wire pay-off bin. Eventually, each coil cylinder mounting bracket extends out to the outside through the corresponding access opening, so that each coil cylinder is exposed outside the can-shaped wire pay-off bin, facilitating the disassembly, installation and replacement of the coil cylinder. After the replacement is completed, the second driving mechanism works to drive each coil cylinder mounting bracket to retract into the can-shaped wire pay-off bin. The exposed replacement of the coil cylinder has a large operating space, reduces the replacement difficulty, saves time and effort, and has high efficiency.

[0008] Preferably, the second driving mechanism includes a motor frame, a bidirectional threaded rod, a driving motor, a first bearing seat, a second bearing seat and a T-shaped connecting seat. The motor frame is fixed on the end of the driving main shaft located inside the can-shaped wire pay-off bin. The driving motor is fixed on the motor frame. The bidirectional threaded rod is fixed on the output shaft of the driving motor and extends coaxially with the can-shaped wire pay-off bin. The first bearing seat is threadedly sleeved on one side of the bidirectional threaded rod, and the second bearing seat is threadedly sleeved on the other side of the bidirectional threaded rod. A guide rod is also fixed on the motor frame. The first bearing seat and the second bearing seat are both slidably sleeved on the guide rod. A number of first traction arms distributed in an annular array are hinged on the first bearing seat, and a number of second traction arms distributed in an annular array are hinged on the second bearing seat. The positions of the first traction arms and the second traction arms correspond one by one. A T-shaped connecting seat is jointly installed at the ends of the first traction arm and the corresponding second traction arm that are close to each other. The T-shaped connecting seat is hinged to both the first traction arm and the second traction arm. The coil cylinder mounting brackets are installed on the T-shaped connecting seats one by one.

[0009] Preferably, a connecting rod is coaxially fixed on the end of the bidirectional threaded rod away from the driving motor. Support arms are annularly arranged on the outer peripheral wall of the connecting rod. A cleaning cylinder seat is rotatably installed at the end of each support arm. The positions of the cleaning cylinder seats correspond to the positions of the coil cylinder mounting brackets one by one. The cable core wires pass through each cleaning cylinder seat one by one.

[0010] Preferably, an annular dust suction seat is fixed at the position corresponding to the cleaning cylinder seat on the inner wall of the can-shaped wire pay-off bin. An inner cavity distributed around the axis of the can-shaped wire pay-off bin is provided in the annular dust suction seat. Dust suction holes communicating with the inner cavity are evenly distributed on the inner edge wall of the annular dust suction seat. An interface provided on the annular dust suction seat and communicating with the inner cavity extends through to the outside of the can-shaped wire pay-off bin and is connected to an industrial strong vacuum cleaner through a dust suction pipe. The dust suction ranges of two adjacent dust suction holes on the inner edge wall of the annular dust suction seat overlap.

[0011] Preferably, a dirt scraping box is installed on each arm. The dirt scraping box is movably attached to the end face of the cleaning cylinder seat on the side close to the driving main shaft. A gear is fixedly sleeved outside each cleaning cylinder seat, and a toothed ring is fixed on the inner edge wall of the annular dust suction seat. Each gear is meshed with the toothed ring correspondingly. When the cleaning cylinder seat rotates, the dirt scraping box can scrape the dirt accumulated on the end face of the cleaning cylinder seat on the side close to the driving main shaft and guide it into the dirt scraping box for collection.

[0012] Preferably, the dirt scraping box is in a quarter-circular ring shape, and both ends of the dirt scraping box have openings. When the cable core wires are twisted and the cleaning cylinder seat rotates, one opening of the dirt scraping box serves as an air inlet, and the other opening serves as an air outlet. The cross-sectional dimension of the internal cavity of the dirt scraping box becomes smaller closer to the air outlet. The air outlets of each dirt scraping box face the inner edge wall of the annular dust suction seat. The dirt scraping box is made of a magnetic metal material, and magnets are installed on each arm. The clamping seats on the side of the dirt scraping box are magnetically fixed to the magnets one by one.

[0013] Preferably, the magnets used are electromagnet seats. Each electromagnet seat is fixedly installed on the arm correspondingly. A pair of positioning rods are fixed on each electromagnet seat, and a pair of jacks are provided on each clamping seat. When the clamping seat is magnetically fixed to the electromagnet seat correspondingly, the positioning rods are inserted into the jacks one by one in a matching manner.

[0014] Preferably, an annular cover is slidably sleeved on the outer peripheral wall of the can-shaped wire pay-off bin in a matching manner. A first driving mechanism is provided on both the annular cover and the can-shaped wire pay-off bin. The first driving mechanism is used to drive the annular cover to feed and retract along the outer wall of the can-shaped wire pay-off bin. When the annular cover is fed to the limit position, the annular cover covers and seals each access opening.

[0015] Preferably, the first driving mechanism includes a fixed seat, an electric push cylinder, and a connecting frame. The electric push cylinder is fixed on the outer wall of the annular cover through the fixed seat, the connecting frame is fixed on the outer wall of the can-shaped wire pay-off bin, and the end of the telescopic rod of the electric push cylinder is fixed to the connecting frame correspondingly.

[0016] Preferably, this cable pipe stranding machine further includes a base. Two vertical column frames extending upward are fixed on the base, and the can-shaped wire pay-off bin is fixed on the tops of the two column frames.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows.

[0018] After the cable core wires on the winding drum are used up, the present invention works through the second driving mechanism to drive each winding drum mounting rack to feed toward the periphery of the can-shaped wire pay-off bin. Finally, each winding drum mounting rack extends out of the corresponding access opening to the outside, so that each winding drum is exposed outside the can-shaped wire pay-off bin, which is convenient for the disassembly and replacement of the winding drum. After the replacement is completed, the second driving mechanism works to drive each winding drum mounting rack to retract into the can-shaped wire pay-off bin. The exposed replacement of the winding drum has a large operating space, reduces the replacement difficulty, saves time and effort, and has high efficiency.

[0019] In the present invention, each cable core passes through each cleaning cylinder seat one by one. During the continuous stranding process of the cable, each core moves relative to the cleaning cylinder seat. The cleaning cylinder seat can scrape off the dirt adhering to the outer surface of the core, realizing the cleaning of the outer surface of the cable core, avoiding the influence of dirt on the stranding and shaping of the cable. In addition, by arranging a connecting rod, a support arm and a cleaning cylinder seat in the can-shaped wire pay-off bin, it is used for the branch-line conveying of the cable core, and at the same time, the cleaning cylinder seat serves as a cleaning part for the cable, killing two birds with one stone.

[0020] In the present invention, an industrial strong vacuum cleaner works to generate negative pressure. The air outside the can-shaped wire pay-off bin is sucked into the can-shaped wire pay-off bin from both ends thereof, and enters the inner cavity through the dust suction holes, and finally is sucked into the industrial vacuum cleaner by the dust suction pipe. Furthermore, a flowing dust suction air flow is formed in the can-shaped wire pay-off bin, which can suck off the dirt floating in the can-shaped wire pay-off bin, avoiding secondary pollution to the cable. In addition, when sucking dust, the external air enters the can-shaped wire pay-off bin from both ends to make up for it, ensuring that the coverage range of the flowing dust suction air flow is large and improving the cleaning effect.

[0021] In the present invention, by arranging a gear and a toothed ring, during the rotation of the connecting rod, the gear and the toothed ring are engaged to drive the cleaning cylinder seat to rotate self. By installing a scraping box on the support arm to fit the end face where dirt accumulates on the cleaning cylinder seat, during the self-rotation of the cleaning cylinder seat, the scraping box moves relative to the cleaning cylinder seat, and the scraping box can scrape and push the dirt accumulated on the end face of the cleaning cylinder seat into its interior for collection, avoiding the adverse effects caused by dirt accumulation on the end face of the cleaning cylinder seat, and at the same time avoiding the difficulty of collecting dirt falling into the can-shaped wire pay-off bin.

[0022] In the present invention, since the scraping box rotates synchronously with the connecting rod and the support arm, the scraping box will move relative to the air in the can-shaped wire pay-off bin. The air is poured into the scraping box from the air inlet of the scraping box and flows out from the air outlet. At the same time, the cross-sectional dimension of the internal cavity of the scraping box becomes smaller and smaller near the air outlet. The air enters from the air inlet with a larger cross-sectional dimension and is discharged from the air outlet with a smaller cross-sectional dimension, which will form an accelerated air flow in the scraping box. At the same time, the air outlets of each scraping box face the inner edge wall of the annular dust suction seat, which can blow the dirt with lighter weight towards the inner edge wall of the annular dust suction seat, facilitating the suction of the dirt. In addition, the dust suction ranges of two adjacent dust suction holes on the inner edge wall of the annular dust suction seat overlap, ensuring that the dust suction range is sufficient to cover each cleaning cylinder seat, improving the effect of capturing dirt.

[0023] The scraping box in the present invention contacts with a magnet, making the scraping box have a magnetic attraction effect. When the scraping box scrapes the dirt on the end face of the cleaning cylinder seat, it can magnetically attract metal scraps such as chips and particles on the scraping box, ensuring that the metal powder will not fall into the can-shaped wire pay-off bin or be sucked away by the dust suction air flow, realizing the screening-type collection of metal scraps and facilitating the recycling of metal scraps.

[0031] This cable tube stranding machine includes a can-shaped wire pay-off bin 1, a base 13, a driving main shaft 4, and a bobbin mounting frame 5. Two vertical column frames 14 are fixed on the base 13. The can-shaped wire pay-off bin 1 is fixed on the tops of the two column frames 14. The can-shaped wire pay-off bin 1 is supported and elevated by the column frames 14. The cross-section of the can-shaped wire pay-off bin 1 is circular and extends horizontally. One end of the can-shaped wire pay-off bin 1 is provided with a shaft mounting frame 12. The driving main shaft 4 is rotatably mounted on the shaft mounting frame 12 and is coaxial with the can-shaped wire pay-off bin 1.

[0032] One end of the driving main shaft 4 extends into the can-shaped wire pay-off bin 1, and the other end extends outside the can-shaped wire pay-off bin 1. A second driving mechanism 6 is provided at the end of the driving main shaft 4 located inside the can-shaped wire pay-off bin 1. A number of bobbin mounting frames 5 are arranged in a circular array around the axis of the can-shaped wire pay-off bin 1 through the second driving mechanism 6. In this application, the number of bobbin mounting frames 5 is preferably four. The outer end of the driving main shaft 4 is in transmission connection with a driving device (not shown in the figure) to provide drive for the rotation and operation of the stranding machine. The cable core bobbins are respectively mounted on the bobbin mounting frames 5, and the cable cores are released from the bobbins. Each cable core passes through a wire combining die (not shown in the figure) after being led out from the can-shaped wire pay-off bin 1, and then is pulled by a traction mechanism (not shown in the figure) and finally wound on a take-up mechanism (not shown in the figure). Each mechanism cooperates to work to realize the stranding of the cable cores. In addition, a tension control module (not shown in the figure) is also provided in the can-shaped wire pay-off bin 1 to control the tension of the cable cores.

[0033] The second driving mechanism 6 is used to drive each bobbin mounting frame 5 to feed and retract along the corresponding radial direction of the can-shaped wire pay-off bin 1. A number of passage openings 11 for the bobbin mounting frames 5 to pass through are evenly arranged in an array around the axis on the outer peripheral wall of the can-shaped wire pay-off bin 1. The number of passage openings 11 is the same as that of the bobbin mounting frames 5. When the second driving mechanism 6 drives each bobbin mounting frame 5 to feed to the limit position, each bobbin mounting frame 5 can respectively pass through the corresponding passage opening 11 and extend outside the can-shaped wire pay-off bin 1.

[0034] After the cable cores on the bobbins are used up, the second driving mechanism 6 works to drive each bobbin mounting frame 5 to feed towards the periphery of the can-shaped wire pay-off bin 1. Finally, each bobbin mounting frame 5 extends outside through the corresponding passage opening 11, so that each bobbin is exposed outside the can-shaped wire pay-off bin 1, which is convenient for the disassembly, replacement and installation of the bobbins. After the replacement is completed, the second driving mechanism 6 works to drive each bobbin mounting frame 5 to retract into the can-shaped wire pay-off bin 1. The exposed replacement of the bobbins has a large operating space, reduces the replacement difficulty, saves time and effort, and has high efficiency.

[0035] Such as Figure 4 and Figure 9As shown in the figure, the second driving mechanism 6 includes a motor frame 61, a bidirectional threaded rod 62, a driving motor 63, a first bearing seat 64, a second bearing seat 65 and a T-shaped connecting seat 66. The motor frame 61 is fixed to the end of the driving main shaft 4 located inside the can-shaped wire pay-off bin 1. The driving motor 63 is fixed to the motor frame 61. The bidirectional threaded rod 62 is fixed to the output shaft of the driving motor 63 and extends coaxially with the can-shaped wire pay-off bin 1. The first bearing seat 64 is threadedly sleeved on one side of the bidirectional threaded rod 62, and the second bearing seat 65 is threadedly sleeved on the other side of the bidirectional threaded rod 62. A guide rod 601 is also fixed to the motor frame 61. The first bearing seat 64 and the second bearing seat 65 are both slidably sleeved on the guide rod 601. A plurality of first traction arms 67 distributed in an annular array are hinged to the first bearing seat 64, and a plurality of second traction arms 68 distributed in an annular array are hinged to the second bearing seat 65. The positions of the first traction arms 67 and the second traction arms 68 correspond one by one. A T-shaped connecting seat 66 is jointly installed at the ends of the first traction arm 67 and the corresponding second traction arm 68 that are close to each other. The T-shaped connecting seat 66 is hinged to both the first traction arm 67 and the second traction arm 68. The coiling cylinder mounting brackets 5 are installed on the T-shaped connecting seats 66 one by one.

[0036] By the forward rotation of the driving motor 63, its output shaft drives the bidirectional threaded rod 62 to rotate. The rotating bidirectional threaded rod 62 threadedly drives the first bearing seat 64 and the second bearing seat 65 to approach each other along the guide rod 601. Under the traction and connection of the first traction arm 67 and the second traction arm 68, the T-shaped connecting seat 66 and the coiling cylinder mounting bracket 5 can be driven to move towards the periphery of the can-shaped wire pay-off bin 1, and finally drive the coiling tape to extend out of the can-shaped wire pay-off bin 1 through the access opening 11, so as to facilitate the disassembly and replacement of the coiling cylinder. After the coiling cylinder is replaced, by the reverse rotation of the driving motor 63, the T-shaped connecting seat 66 and the coiling cylinder mounting bracket 5 as a whole can be driven to retract into the can-shaped wire pay-off bin 1 to ensure that the replaced coiling cylinder can be installed in place.

[0037] In addition, it is worth noting that a driving motor 51 is fixed to each T-shaped connecting seat 66, and the coiling cylinder mounting brackets 5 are fixed to the output shafts of the driving motors 51 one by one. During the process of winding and stranding, the driving motor 51 works to drive the coiling cylinder mounting bracket 5 and the coiling cylinder to rotate. By the rotation of the coiling cylinder, the cable core wires can be evenly released, avoiding inconsistent cable core wire structures caused by uneven wire pay-off, reducing the friction between the cable core wires and the coiling cylinder, and reducing wear. In addition, the release speed of the cable core wires can be adjusted to control the tension, preventing the core wires from being overly loose or too tight.

[0038] Such as Figure 3 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 8As shown in the figure, a connecting rod 7 is coaxially fixed to the end of the bidirectional threaded rod 62 away from the driving motor 63. Support arms 71 are arranged in a circular array on the outer peripheral wall of the connecting rod 7. A cleaning cylinder seat 8 is rotatably installed at the end of each support arm 71. The positions of the cleaning cylinder seats 8 correspond one by one to the positions of the coiling cylinder mounting brackets 5. Before each cable core wire is led out of the can-shaped wire pay-off bin 1, each cable core wire passes through the corresponding cleaning cylinder seat 8 one by one. During the continuous stranding of the cable, each core wire moves relative to the cleaning cylinder seat 8. The cleaning cylinder seat 8 can scrape off the dirt attached to the outer surface of the core wire, realizing the cleaning of the outer surface of the cable core wire and avoiding the influence of dirt on the stranding and shaping of the cable. In addition, by arranging the connecting rod 7, the support arms 71 and the cleaning cylinder seats 8 in the can-shaped wire pay-off bin 1, it is used for the branch feeding of the cable core wire, and at the same time, the cleaning cylinder seat 8 also serves as a cleaning part for the cable, killing two birds with one stone.

[0039] Some of the dirt scraped off by the cleaning cylinder seat 8 will float in the can-shaped wire pay-off bin 1. In order to avoid the dirt falling on the cable again and causing secondary pollution, the present invention makes the following improvements: An annular dust suction seat 9 is fixed at the position corresponding to the cleaning cylinder seat 8 on the inner wall of the can-shaped wire pay-off bin 1. An inner cavity 91 distributed around the axis of the can-shaped wire pay-off bin 1 is provided in the annular dust suction seat 9. Dust suction holes 92 communicating with the inner cavity 91 are evenly distributed on the inner edge wall of the annular dust suction seat 9. An interface 93 provided on the annular dust suction seat 9 and communicating with the inner cavity 91 extends through to the outside of the can-shaped wire pay-off bin 1 and is connected to an industrial strong vacuum cleaner (not shown in the figure) through a dust suction pipe.

[0040] By the operation of the industrial strong vacuum cleaner, negative pressure is generated. The air outside the can-shaped wire pay-off bin 1 is sucked into the can-shaped wire pay-off bin 1 from both ends thereof and enters the inner cavity 91 through the dust suction holes 92, and finally is sucked into the industrial vacuum cleaner through the dust suction pipe. Thus, a flowing dust suction air flow is formed in the can-shaped wire pay-off bin 1, and the dirt floating in the can-shaped wire pay-off bin 1 can be sucked off, avoiding secondary pollution to the cable. In addition, when sucking dust, the outside air enters the can-shaped wire pay-off bin 1 from both ends for supplement, ensuring that the coverage range of the flowing dust suction air flow is large and improving the cleaning effect.

[0041] Since when using the cleaning cylinder seat 8 to scrape off the dirt on the outer surface of the core wire, the dirt is likely to accumulate between the end face of the cleaning cylinder seat 8 and the outer surface of the cable, and excessive accumulation of the dirt is likely to bring adverse effects. To solve this problem, the present invention makes the following improvements: A scraping dirt box 81 is installed on each support arm 71. The scraping dirt box 81 is movably attached to the end face of the cleaning cylinder base 8 on the side close to the driving main shaft 4. A gear 82 is fixedly sleeved outside each cleaning cylinder base 8, and a toothed ring 83 is fixed on the inner edge wall of the annular dust suction base 9. Each gear 82 is meshed with the toothed ring 83 correspondingly. When the cleaning cylinder base 8 rotates, the scraping dirt box 81 can scrape the dirt accumulated on the end face of the cleaning cylinder base 8 on the side close to the driving main shaft 4 and introduce it into the scraping dirt box 81 for collection.

[0042] By arranging the gear 82 and the toothed ring 83, during the rotation of the connecting rod 7, the gear 82 and the toothed ring 83 are meshed to drive the cleaning cylinder base 8 to rotate. By installing on the support arm 71 to fit with the end face where dirt accumulates on the cleaning cylinder base 8, during the rotation of the cleaning cylinder base 8, the scraping dirt box 81 and the cleaning cylinder base 8 move relatively. The scraping dirt box 81 can scrape and push the dirt accumulated on the end face of the cleaning cylinder base 8 into its interior for collection, avoiding the adverse effects caused by dirt accumulation on the end face of the cleaning cylinder base 8, and also avoiding dirt from falling into the tank-shaped wire laying bin 1 and being difficult to collect.

[0043] Since the dirt contains metal scraps such as chips and particles generated during processing, the debris waste is heavy, easy to fall into the tank-shaped wire laying bin 1, and difficult to collect. At the same time, it is not conducive to the recycling of metal scraps. To solve this problem, the present invention makes the following improvements: The scraping dirt box 81 is in a quarter-circular ring shape, and both ends of the scraping dirt box 81 have openings. When the cable core wires are twisted and the cleaning cylinder base 8 rotates, one opening of the scraping dirt box 81 serves as an air inlet, and the other opening serves as an air outlet. Since the scraping dirt box 81 rotates synchronously with the connecting rod 7 and the support arm 71, the scraping dirt box 81 will move relatively with the air in the tank-shaped wire laying bin 1. As Figure 8 shown, the air is poured into the scraping dirt box 81 from the air inlet of the scraping dirt box 81 and flows out from the air outlet. Figure 8 In the figure, the solid arrow is the movement direction of the cleaning cylinder base 8, and the dashed arrow is the air flow direction in the scraping dirt box 81. At the same time, the cross-sectional dimension of the internal cavity of the scraping dirt box 81 is smaller closer to the air outlet. The air enters from the air inlet with a larger cross-sectional dimension and exits from the air outlet with a smaller cross-sectional dimension, which will form an accelerated air flow in the scraping dirt box 81. At the same time, the air outlets of each scraping dirt box 81 are all oriented towards the inner edge wall of the annular dust suction base 9, which can blow the dirt with lighter weight towards the inner edge wall of the annular dust suction base 9, facilitating the suction of the dirt. In addition, the suction ranges of two adjacent suction holes 92 on the inner edge wall of the annular dust suction base 9 overlap, ensuring that the suction range is sufficient to cover each cleaning cylinder base 8 and improving the effect of capturing dirt.

[0044] The scraping box 81 is made of magnetic metal material, and magnets are installed on each arm 71. The clamping seats 811 on the side of the scraping box 81 are magnetically fixed to the magnets one by one. The scraping box 81 is in contact with the magnets, so that the scraping box 81 has a magnetic attraction effect. When the scraping box 81 scrapes the dirt on the end face of the cleaning cylinder seat 8, metal wastes such as debris and particles can be magnetically attracted to the scraping box 81, ensuring that the metal powder will not fall into the can-shaped wire pay-off bin 1 or be sucked away by the suction air flow, realizing the screening collection of metal wastes and facilitating the recycling of metal wastes.

[0045] As Figure 8 shown, the magnet used is an electromagnet seat 84. The scraping box 81 has a magnetic attraction effect when electrified, and the magnetism disappears after power-off. Each electromagnet seat 84 is fixedly arranged on the arm 71, and a pair of positioning rods 85 are fixed on each electromagnet seat 84. A pair of jacks 812 are arranged on each clamping seat 811. When the clamping seat 811 is magnetically fixed to the electromagnet seat 84, the positioning rods 85 are inserted into the jacks 812 one by one in a matching manner.

[0046] Magnetically fixing the clamping seat 811 to the electromagnet seat 84 and ensuring that the positioning rods 85 are correspondingly inserted into the jacks 812 can position and install the scraping box 81, and can prevent the scraping box 81 from shifting or being misaligned. After the tube stranding machine works for a period of time and stops for maintenance, the collection container is taken into the can-shaped wire pay-off bin 1 and placed below the scraping box 81. Then the electromagnet seat 84 is powered off, and the magnetism disappears. Then the metal wastes collected on the scraping box 81 will fall into the collection container. At the same time, taking the clamping seat 811 off the electromagnet seat 84 also facilitates the cleaning of the surface of the scraping box 81.

[0047] As Figure 1 and Figure 2 shown, an annular cover 2 is slidably sleeved on the outer peripheral wall of the can-shaped wire pay-off bin 1 in a matching manner. A first driving mechanism 3 is jointly arranged on the annular cover 2 and the can-shaped wire pay-off bin 1. The first driving mechanism 3 is used to drive the annular cover 2 to feed and retract along the outer wall of the can-shaped wire pay-off bin 1. When the annular cover 2 is fed to the limit position, the annular cover 2 covers and seals each passage port 11.

[0048] The first driving mechanism 3 includes a fixed seat 31, an electric push cylinder 32 and a connecting frame 33. The electric push cylinder 32 is fixed to the outer wall of the annular cover 2 through the fixed seat 31. The connecting frame 33 is fixed to the outer wall of the can-shaped wire pay-off bin 1. The end of the telescopic rod of the electric push cylinder 32 is correspondingly fixed to the connecting frame 33.

[0049] An annular cover 2 and a first driving mechanism 3 are added to the outside of the tank-shaped wire-paying bin 1. The electric push cylinder 32 is extended, and the telescopic rod of the electric push cylinder 32 can push the annular cover 2 in the reverse direction to move toward the interface 93 under the connection of the connecting frame 33, so that the annular cover 2 can block all the passages 11. On the one hand, it can prevent dirt from leaking out of the passages 11, and at the same time ensure that the tank-shaped wire-paying bin 1 can form a stable dust-absorbing airflow from both ends. On the other hand, when the wire is twisted, it can prevent the staff from touching the internal components of the tank-shaped wire-paying bin 1 and causing safety accidents. In addition, the electric push cylinder 32 is retracted to drive the annular cover 2 to move away from the interface 93, canceling the blockage of the passage 11, making it convenient to replace the winding drum, inspect and maintain the internal components of the tank-shaped wire-paying bin 1, and transfer the metal waste collected in the tank-shaped wire-paying bin 1.

[0050] It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.
