Description

Technical Field

[0001] The invention belongs to the technical field of stranding machines, in particular to a cable stranding machine for stranding wire cores synchronously at multiple workstations. Background Art

[0002] Cable stranding machine is a kind of mechanical equipment widely used in the manufacture of wires and cables. It is mainly used to twist multiple single conductors into one strand to meet the process requirements of the wire. Its working principle is to make the single conductors spirally wound together through the combined action of the circular motion of the twisting bow and the forward motion of the machine to form a conductor with a larger diameter.

[0003] The prior art also proposes some cable stranding machine solutions. For example, a patent application with publication number CN118522504A discloses an automatic loading device for a stranding machine, including a support seat, a rotating shaft, a supporting plate, a clamping plate, a winding roller, a driving structure, a spool, a limit plate, a protrusion one, a limit turntable one and a limit turntable two. By setting a loading structure and a roller changing structure, the automatic loading and unloading of the winding roller can be effectively realized. Due to the setting of the limit plate, the protrusion one, the limit turntable one and the limit turntable two, the winding roller can fall autonomously from between the two clamping plates at the set position, thereby avoiding the disadvantages of manual removal of the winding roller; and with the help of the loading structure, the winding roller is allowed to enter between the two limit turntables, so that automatic loading can be realized, thereby reducing the workload of manual loading.

[0004] The automatic loading device of the stranding machine in the above technology can only replace one winding roller at a time. Therefore, when faced with the more widely used multi-station synchronous stranded wire core cable stranding machine, since it can only replace one winding roller at a time, and the same column of the multi-station synchronous stranded wire core cable stranding machine has multiple winding rollers, this greatly slows down the efficiency of winding roller replacement, thereby affecting production efficiency.

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figure 1 、 Figure 2 and Figure 5As shown, a cable stranding machine for stranding wire cores at multiple stations synchronously according to an embodiment of the present invention comprises a base 1; a driving tube 2 is rotatably connected to the top of the base 1, and the driving tube 2 is driven by an internal combustion engine; baffles 3 are fixedly connected to both ends of the driving tube 2; four evenly arranged support frames 4 are fixedly connected between two of the baffles 3; a distribution plate 5 is fixedly connected to the side of one of the baffles 3 away from the support frame 4; a plurality of evenly arranged inserts 6 are fixedly connected to the side of the support frame 4 away from the driving tube 2, and the inserts 6 are driven by an electric push rod 23; the base A pair of symmetrically arranged moving seats 7 are slidably connected to one side of the seat 1, and the moving seat 7 is driven by a servo motor 1; a rotating frame 8 is rotatably connected between the two moving seats 7, and the rotating frame 8 is driven by a servo motor 2; a plurality of evenly arranged fixed plates 9 are fixedly connected to the surface of the rotating frame 8 at both sides; the fixed plates 9 are arranged in a one-to-one correspondence with the cannula 6; a moving plate 10 is slidably connected to one side of the fixed plate 9 on the surface of the rotating frame 8; the fixed plate 9 and the moving plate 10 are both L-shaped; the moving plate 10 on the same side is driven by a threaded rod;During operation, when twisting the wires, the user needs to first pass a strand of wire through the hole in the center of the driving tube 2 and the distribution plate 5, and then the user needs to pass the cable on the winding shaft between the paired support frames 4 through the hole on the surface of the distribution plate 5, and twist it into a strand with the cable that has previously passed through the driving tube 2, and then connect the twisted cable to the traction machine. Then, while the traction machine continuously pulls the cable, the driving tube 2 rotates, thereby driving the cable at the support frame 4 to be twisted to the surface of the cable passing through the driving tube, thereby completing the twisting of the cable. In order to facilitate the synchronous loading and unloading of the multi-station cable twisting machine, the embodiment of the present invention can be used. First, when the winding shaft needs to be replaced, Before replacement, the user needs to stop the machine first to stop the rotation of the drive tube 2, and then the user rotates the baffle 3 so that the winding shaft between the two support frames 4 is aligned with the fixed plate 9 and the movable plate 10 on the surface of the rotating frame 8. Then the user installs the winding shaft to be replaced between the movable plate 10 and the fixed plate 9 on the side of the rotating frame 8 away from the drive tube 2. Then the movable seat 7 drives the rotating frame 8 to move between the paired support frames 4, and moves the movable plate 10 and the fixed plate 9 on the side of the rotating frame 8 close to the drive tube 2 to the position of the used winding shaft. After that, the movable plate 10 slides synchronously toward the fixed plate 9, so that the fixed plate 9 and the movable plate 10 clamp the used winding shaft. After the winding spool is used up, the cannula 6 is pulled out from the inside of the winding spool under the drive of the electric push rod 23, and then the movable seat 7 is moved in the direction away from the driving tube 2, thereby moving the used winding spool out from between the paired support frames 4, and then the rotating frame 8 is rotated to rotate the unused replacement winding spool on the other side to the side close to the rotating frame 8 close to the driving tube 2, and then the movable seat 7 is moved between the paired support frames 4 again, and the winding spool to be replaced is stuffed between the paired support frames 4, and then the electric push rod 23 drives the cannula 6 to be inserted into the interior of the winding spool, thereby completing the fixation of the winding spool, and then the user only needs to rotate the baffle 3 so that the other pair of supports The frame 4 is moved toward the rotating frame 8, and then the above replacement steps are repeated to gradually complete the replacement of all the spools. After that, the user can normally pass the cable on the newly replaced winding spool through the distribution plate 5 to carry out the subsequent twisting operation. Therefore, through the cooperation of the movable seat 7, the rotating frame 8, the fixed plate 9 and the movable plate 10, the winding spools at multiple stations between the paired support plates can be replaced synchronously, which can effectively shorten the replacement time of the winding spools and thus improve production efficiency. At the same time, the loading and unloading are completed by the movable seat 7, the rotating frame 8, the fixed plate 9 and the movable plate 10, which can reduce the manual operation of the user and reduce the difficulty of the user's operation.

[0023] like Figures 1 to 3As shown, a plurality of evenly arranged trays 11 are fixedly connected to the side of the support frame 4 away from the cannula 6; the trays 11 and the cannula 6 are arranged in a one-to-one correspondence; the surface of the tray 11 is slidably connected to a limit tube 12; the limit tube 12 and the cannula 6 are fixedly connected to a tooth plate 13 on the side close to each other; a gear 14 is connected to the two tooth plates 13 for common rotation; the gear 14 is rotatably connected to the driving rod; when working, when the winding shaft is fed between the paired support frames 4 and placed on the top surface of the tray 11, the cannula 6 will move toward the inside of the winding shaft under the drive of the electric push rod 23. During this process, the insert tube 6 will drive the tooth plate 13 fixed to itself to move together, and the tooth plate 13 will drive the gear 14 to rotate, and then drive the tooth plate 13 fixed to the limiting tube 12 on the other side to move, thereby realizing the synchronous movement of the insert tube 6 and the limiting tube 12, so that the two ends of the winding shaft are respectively inserted into the insert tube 6 and the limiting tube 12, thereby effectively preventing the winding shaft from falling out from between the paired support frames 4, and at the same time, when the driving tube 2 drives the support frame 4 and the winding shaft to rotate at high speed, it can provide a limiting effect on the winding shaft, thereby reducing the probability of the winding shaft being thrown out of the embodiment of the present invention.

[0024] like Figures 3 and 4 As shown, a pressure plate 15 is fixedly connected to the surface of the insert tube 6; an annular groove 16 is provided on the side where the tray 11 and the pressure plate 15 are close to each other; a plurality of evenly arranged balls 17 are arranged in the annular groove 16; lubricating oil is provided in the balls 17 and the annular groove 16; during operation, when the insert tube 6 and the limiting tube 12 move toward each other to fix the winding shaft, the pressure plate 15 on the surface of the insert tube 6 will move toward the winding shaft, and then cooperate with the tray 11 to clamp the winding shaft, thereby further fixing the winding shaft to prevent the driving tube 2 from sliding when driving the winding shaft to rotate, causing the cable drawn out from the inside to wear. At the same time, the balls 17 in the annular groove 16 on the surfaces of the tray 11 and the pressure plate 15 cooperate with the lubricating oil to reduce the friction of the winding shaft when the surfaces of the two rotate, thereby reducing the wear of the two and increasing the service life of the two.

[0025] like Figure 1 、 Figure 5 and Figure 6As shown, the fixed plate 9 and the movable plate 10 are both installed with a limit plate 18 on the side close to each other; the two limit plates 18 are staggered; the surfaces of the fixed plate 9 and the movable plate 10 are provided with a clearance groove 19 at the corresponding position of the other limit plate 18, and the clearance groove 19 is adapted to the limit plate 18; during operation, in the process of the winding spool with the cable wound around the clamping surface, the threaded rod will drive the movable plate 10 to move toward the fixed plate 9, and in this process the limit plate 18 will also move toward the clearance groove 19, While the movable plate 10 and the fixed plate 9 clamp the winding shaft, the movable plate 10 and the fixed plate 9 on the side away from the rotating frame 8 can cooperate with the limit plate 18 to achieve the further clamping of the winding shaft to limit the forward and backward and left and right movement of the winding shaft, thereby preventing the rotating frame 8 from rotating when the winding shaft with the surface wrapped with cables is driven to rotate. Due to its own large mass, the winding shaft may shake or collide between the movable plate 10 and the fixed plate 9 during rotation due to inertia, thereby causing damage to the winding shaft.

[0026] like Figure 1 、 Figure 5 and Figure 6 As shown, the interior of the rotating frame 8 is fixedly connected with a connecting rod 20, and the connecting rod 20 is arranged in a hollow structure; one end of the connecting rod 20 passes through the movable seat 7; the surface of the connecting rod 20 is fixedly connected with a connecting pipe 21 at the corresponding position of the limit plate 18; the connecting pipe 21 passes through the rotating frame 8, and the connecting pipe 21 is communicated with the interior of the connecting rod 20; the end of the connecting pipe 21 away from the connecting rod 20 is slidably connected to the push rod 22; the end of the connecting rod 20 passing through the movable seat 7 is threadedly connected to the push rod 23; the interior of the connecting rod 20 is filled with hydraulic oil between the push rod 23 and the push rod 22; the two push rods 23 are fixedly connected with a connecting plate 24 at one end away from the connecting pipe 21; the connecting plate 24 is fixed with the limit position at the fixed plate 9 The plate 18 is fixedly connected and is slidably connected to the limit plate 18 at the movable plate 10; during operation, in order to adapt to reels of different diameters that are wound with cables, the user can screw the push rod 23 at the connecting rod 20, and the push rod 23 squeezes the hydraulic oil inside the connecting tube 21, and then pushes the top rod 22 at the connecting tube 21 through the hydraulic oil, and the top rod 22 pushes the connecting plate 24, and finally the connecting plate 24 drives the limit plate 18 to move, thereby controlling the distance between the limit plate 18 and the end of the movable plate 10 and the fixed plate 9 away from the rotating frame 8, so as to adapt to reels of different diameters, thereby improving the scope of application of the embodiment of the present invention, and the top rods 22 on both sides of the rotating plate are pushed synchronously, avoiding manual adjustment by the user one by one, reducing the difficulty of adjustment.

[0027] like Figures 5 and 6As shown, the top surfaces of the fixed plate 9 and the movable plate 10 are both slidably connected with a plurality of evenly arranged sliding rods 25; the top surfaces of the sliding rods 25 on the same side are commonly fixedly connected with a top plate 26; the top plate 26 is driven by a hydraulic system; during operation, when the movable plate 10 and the fixed plate 9 clamp the winding shaft, the user needs to ensure that the lower surfaces of the fixed plate 9 and the movable plate 10 fit into the bottom surface inside the winding shaft, and then the user pushes the sliding rod 25 and the top plate 26 up through the hydraulic system, so that the top plate 26 rests against the top surface inside the winding shaft, thereby limiting the up and down movement of the winding shaft, that is, the axial movement of the winding shaft, thereby further limiting the winding shaft, and further reducing the shaking of the winding shaft during rotation.

[0028] like Figure 1 and Figure 7 As shown, the top surface of the base 1 is rotatably connected to a pair of symmetrically arranged support rings 27 at the corresponding positions of the drive tube 2; the two support rings 27 are respectively located at the two ends of the drive tube 2; a cover 28 is fixedly connected between the two support rings 27; the cover 28 is a cylindrical structure, and the surface is porous; a feed port 29 is opened on one side of the cover 28; the width of the feed port 29 is the same as the distance between the sides of the paired support frames 4 close to each other; during operation, when the user needs to replace the winding shaft, the user needs to rotate the support ring 27, and the support The support ring 27 drives the cover to rotate and aligns the feed port 29 on the surface of the cover shell 28 with the rotating frame 8. At this time, the movable seat 7 can normally drive the rotating frame 8 to complete the loading operation. When the loading is completed, the user drives the movable seat 7 to move away from the driving tube 2. At this time, the user rotates the support ring 27 again and drives the feed port 29 on the surface of the cover shell 28 to rotate to the top surface of the base 1. At this time, the cover shell 28 can play a protective role to prevent the driving tube 2 from accidentally throwing the winding shaft out of the support frame 4 when driving the winding shaft to rotate at high speed, and injuring the staff nearby.

[0029] like Figure 1 and Figure 7 As shown, the inner side of the support ring 27 is fixedly connected with an internal gear 30; the inner side of the internal gear 30 is meshedly connected with gear 2 31; the two movable seats 7 are fixedly connected with tooth plate 2 32 on one side close to the cover shell 28; the tooth plate 2 32 can be meshed and connected with gear 2 31; during operation, during the replacement of the winding shaft, the movable seat 7 will move toward the driving tube 2, and in the process of movement, the movable seat 7 will drive tooth plate 2 32 to mesh with gear 2 31, and drive gear 2 31 to rotate, and the rotating gear 2 31 will drive the inner gear 30 meshed with it to rotate, and at the same time, the inner gear 30 drives the support ring 27 and the cover shell 28 to rotate, so that the feed port 29 on the surface of the cover shell 28 faces the rotating frame 8 at the movable seat 7, thereby eliminating the need for the user to manually rotate the cover shell 28, thereby reducing the user's operating difficulty and improving the usability of the embodiment of the present invention.

[0030] like Figures 7 and 8 As shown, the two support rings 27 are fixedly connected to a connecting seat 33 on one side close to the movable seat 7; a socket 34 is provided on the surface of the connecting seat 33; a plug rod 35 is installed on the top surface of the base 1; the plug rod 35 is set in an L shape, and the top of the plug rod 35 is adapted to the socket 34; during operation, after the winding shaft at the support frame 4 is replaced, the user needs to insert the plug rod 35 into the socket 34 on the surface of the connecting seat 33, so that the plug rod 35 can limit the connecting seat 33, thereby limiting the rotation of the support ring 27, and preventing the support ring 27 from causing the cover shell 28 to swing due to shaking when the driving tube 2 rotates, thereby causing a safety risk.

[0031] like Figures 7 and 8 As shown, a transmission plate 36 is provided on the side of the movable seat 7 close to the insertion rod 35; an electromagnet block 37 is fixedly connected to the side of the movable seat 7 close to the transmission plate 36; the transmission plate 36 is made of magnetizable metal; the end of the transmission plate 36 away from the movable seat 7 is fixedly connected to the bottom surface of the insertion rod 35; during operation, when the winding shaft needs to be replaced, the electromagnet block 37 on the surface of the movable seat 7 is energized and adsorbs the transmission plate 36. At this time, the movable seat 7 moves in the direction of the drive tube 2, and the transmission plate 36 can drive the insertion rod 35 to disengage from the socket 34 on the surface of the connecting seat 33, and then the electromagnet block 37 is 7 is powered off, and the moving block is no longer attracted by the electromagnetic block. At this time, the moving seat 7 can no longer drive the transmission plate 36 to move, so the support ring 27 remains unlocked. When the winding shaft is replaced, the electromagnet block 37 is energized and attracts the transmission plate 36 again. At this time, the moving seat 7 moves in the direction away from the driving tube 2, and the transmission plate 36 can drive the insertion rod 35 to be reinserted into the socket 34 on the surface of the connecting seat 33, thereby completing the locking of the support ring 27. Therefore, the locking and unlocking of the support ring 27 does not require manual operation by the user, further improving the degree of automation and reducing the difficulty of operation for the user.

[0032] During operation, when twisting the wires, the user needs to first pass a strand of wire through the hole in the center of the driving tube 2 and the distribution plate 5, and then the user needs to pass the cable on the winding shaft between the paired support frames 4 through the hole on the surface of the distribution plate 5, and twist it into a strand with the cable that has previously passed through the driving tube 2, and then connect the twisted cable to the traction machine. Then, while the traction machine continuously pulls the cable, the driving tube 2 rotates, thereby driving the cable at the support frame 4 to be twisted to the surface of the cable passing through the driving tube, thereby completing the twisting of the cable. In order to facilitate the synchronous loading and unloading of the multi-station cable twisting machine, the embodiment of the present invention can be used. First, when the winding shaft needs to be replaced, Before replacement, the user needs to stop the machine first to stop the rotation of the drive tube 2, and then the user rotates the baffle 3 so that the winding shaft between the two support frames 4 is aligned with the fixed plate 9 and the movable plate 10 on the surface of the rotating frame 8. Then the user installs the winding shaft to be replaced between the movable plate 10 and the fixed plate 9 on the side of the rotating frame 8 away from the drive tube 2. Then the movable seat 7 drives the rotating frame 8 to move between the paired support frames 4, and moves the movable plate 10 and the fixed plate 9 on the side of the rotating frame 8 close to the drive tube 2 to the position of the used winding shaft. After that, the movable plate 10 slides synchronously toward the fixed plate 9, so that the fixed plate 9 and the movable plate 10 clamp the used winding shaft. After the winding spool is used up, the cannula 6 is pulled out from the inside of the winding spool under the drive of the electric push rod 23, and then the movable seat 7 is moved in the direction away from the driving tube 2, thereby moving the used winding spool out from between the paired support frames 4, and then the rotating frame 8 is rotated to rotate the unused replacement winding spool on the other side to the side close to the rotating frame 8 close to the driving tube 2, and then the movable seat 7 is moved between the paired support frames 4 again, and the winding spool to be replaced is stuffed between the paired support frames 4, and then the electric push rod 23 drives the cannula 6 to be inserted into the interior of the winding spool, thereby completing the fixation of the winding spool, and then the user only needs to rotate the baffle 3 so that the other pair of supports The frame 4 is directed toward the rotating frame 8, and then the above-mentioned replacement steps are repeated to gradually complete the replacement of all the spools. After that, the user can normally pass the cable on the newly replaced winding spool through the distribution plate 5 to perform the subsequent twisting operation. Therefore, the winding spools at multiple workstations between the paired support plates can be replaced synchronously through the cooperation of the movable seat 7, the rotating frame 8, the fixed plate 9 and the movable plate 10, which can effectively shorten the replacement time of the winding spools and thus improve production efficiency. At the same time, loading and unloading are completed by the movable seat 7, the rotating frame 8, the fixed plate 9 and the movable plate 10, which can reduce the manual operation amount of the user and reduce the difficulty of operation for the user.

[0033] When the winding shaft is sent between the paired support frames 4 and placed on the top surface of the tray 11, the insert pipe 6 will move toward the inside of the winding shaft under the drive of the electric push rod 23. During this process, the insert pipe 6 will drive the tooth plate 13 fixed to itself to move together, and the tooth plate 13 will drive the gear 14 to rotate, and then drive the tooth plate 13 fixed to the limiting tube 12 on the other side to move, thereby realizing the synchronous movement of the insert pipe 6 and the limiting tube 12, so that the two ends of the winding shaft are respectively inserted into the insert pipe 6 and the limiting tube 12, thereby effectively preventing the winding shaft from falling out from between the paired support frames 4, and at the same time, providing a limiting effect on the winding shaft when the driving tube 2 drives the support frame 4 and the winding shaft to rotate at high speed, thereby reducing the probability of the winding shaft being thrown out of the embodiment of the present invention.

[0034] When the insert tube 6 and the limiting tube 12 move toward each other to fix the winding shaft, the pressure plate 15 on the surface of the insert tube 6 will move toward the winding shaft, and then cooperate with the tray 11 to clamp the winding shaft, thereby further fixing the winding shaft to prevent the driving tube 2 from sliding when driving the winding shaft to rotate, causing the cable pulled out from it to wear. At the same time, the balls 17 in the annular grooves 16 on the surfaces of the tray 11 and the pressure plate 15, combined with the lubricating oil, can also reduce the friction of the winding shaft when rotating on the two surfaces, thereby reducing the wear of the two and increasing the service life of the two.

[0035] In the process of clamping the winding shaft with a cable wound around its surface, the threaded rod will drive the movable plate 10 to move toward the fixed plate 9. During this process, the limit plate 18 will also move toward the clearance groove 19. Then, while the movable plate 10 and the fixed plate 9 clamp the winding shaft, the movable plate 10 and the fixed plate 9 on the side away from the rotating frame 8 can cooperate with the limit plate 18 to achieve further clamping of the winding shaft to limit the forward and backward and left and right movement of the winding shaft, thereby preventing the rotating frame 8 from causing the winding shaft to shake or collide between the movable plate 10 and the fixed plate 9 due to inertia during rotation due to its own large mass when driving the winding shaft with a cable wound around its surface, thereby causing damage to the winding shaft.

[0036] In order to adapt to reels full of cables of different diameters, the user can screw the push rod 23 at the connecting rod 20, and the push rod 23 squeezes the hydraulic oil inside the connecting tube 21, and then pushes the push rod 22 at the connecting tube 21 through the hydraulic oil, and the push rod 22 pushes the connecting plate 24, and finally the connecting plate 24 drives the limit plate 18 to move, thereby controlling the distance between the limit plate 18 and the end of the movable plate 10 and the fixed plate 9 away from the rotating frame 8, so as to adapt to reels of different diameters, thereby improving the scope of application of the embodiment of the present invention, and the push rods 22 on both sides of the rotating plate are pushed synchronously, avoiding manual adjustment by the user one by one, reducing the difficulty of adjustment.

[0037] When the movable plate 10 and the fixed plate 9 clamp the winding shaft, the user needs to ensure that the lower surfaces of the fixed plate 9 and the movable plate 10 fit into the bottom surface inside the winding shaft, and then the user pushes the slide rod 25 and the top plate 26 up through the hydraulic system, so that the top plate 26 rests against the top surface inside the winding shaft, thereby limiting the up and down movement of the winding shaft, that is, the axial movement of the winding shaft, thereby further limiting the winding shaft, and further reducing the shaking of the winding shaft during rotation.

[0038] When the user needs to replace the winding reel, the user needs to rotate the support ring 27, which drives the cover to rotate and aligns the feed port 29 on the surface of the cover shell 28 with the rotating frame 8. At this time, the movable seat 7 can normally drive the rotating frame 8 to complete the loading operation. When the loading is completed, the user drives the movable seat 7 to move away from the driving tube 2. At this time, the user rotates the support ring 27 again and drives the feed port 29 on the surface of the cover shell 28 to rotate to the top surface of the base 1. At this time, the cover shell 28 can play a protective role to prevent the driving tube 2 from accidentally throwing the winding reel out of the support frame 4 when driving the winding reel to rotate at high speed, and injuring the staff nearby.

[0039] During the replacement of the winding shaft, the movable seat 7 will move toward the driving tube 2, and during the movement, the movable seat 7 will drive the tooth plate 2 32 to engage with the gear 2 31, and drive the gear 2 31 to rotate, and the rotating gear 2 31 will drive the internal gear 30 engaged with it to rotate, and at the same time, the internal gear 30 drives the support ring 27 and the cover shell 28 to rotate, so that the feed port 29 on the surface of the cover shell 28 faces the rotating frame 8 at the movable seat 7, thereby eliminating the need for the user to manually rotate the cover shell 28, thereby reducing the user's operating difficulty and improving the usability of the embodiment of the present invention.

[0040] After the winding spool at the support frame 4 is replaced, the user needs to insert the rod 35 into the socket 34 on the surface of the connecting seat 33. In this way, the rod 35 can limit the connecting seat 33, thereby limiting the rotation of the support ring 27, and preventing the support ring 27 from causing the cover shell 28 to swing due to shaking when the driving tube 2 rotates, thereby causing a safety risk.

[0041] When the winding spool needs to be replaced, the electromagnet block 37 on the surface of the movable seat 7 is energized and attracts the transmission plate 36. At this time, the movable seat 7 moves in the direction of the driving tube 2, and the transmission plate 36 can drive the insertion rod 35 to disengage from the socket 34 on the surface of the connecting seat 33. Then the electromagnet block 37 is powered off, and the movable block is no longer attracted by the electromagnet block. At this time, the movable seat 7 can no longer drive the transmission plate 36 to move, so the support ring 27 remains unlocked. When the winding spool is replaced, the electromagnet block 37 is energized and attracts the transmission plate 36 again. At this time, the movable seat 7 moves in the direction away from the driving tube 2, and the transmission plate 36 can drive the insertion rod 35 to be reinserted into the socket 34 on the surface of the connecting seat 33, thereby completing the locking of the support ring 27. Therefore, the locking and unlocking of the support ring 27 does not require manual operation by the user, further improving the degree of automation and reducing the difficulty of operation for the user.
