Description

Technical Field

[0001] The present invention relates to the field of cable production equipment, and particularly to a fully automatic cable reel film covering equipment. Background Art

[0002] During the production of cables, in order to improve the film covering packaging efficiency of cable reels, an automatic film covering machine for blasting cable reels with a publication number of CN117048911B is publicly available on the market. A conveying mechanism and a film sleeving mechanism are arranged on the bracket of the automatic film covering machine. An annular guide rail is arranged on the conveying mechanism, and a plurality of sliding seats are movably arranged on the annular guide rail. Claw holders are arranged on the sliding seats. A rotary clutch seat capable of engaging and disengaging with the sliding seat is arranged on the bracket on the same side as the arc section of the annular guide rail. A moving clutch seat fixedly connected to the right synchronous belt conveying module and slidably clamped with the right linear guide rail is arranged. Two left synchronous belt conveying modules are arranged at intervals on the left side wall of the bracket. One left synchronous belt conveying module corresponds to the film sleeving mechanism, and the other left synchronous belt conveying module corresponds to the film shrinking oven. Moving clutch seats fixedly connected to the left synchronous belt conveying modules and slidably clamped with the left linear guide rail are arranged on both of the two left synchronous belt conveying modules. When in use, it is necessary to manually fix the cable reel on the claw holder and then manually feed the material, with low automation. When performing film sleeving and high-temperature film shrinking, in order to prevent the film sleeving work from interfering with the high-temperature film shrinking work, two non-interfering left synchronous belt conveying modules need to be arranged on the left side close to the film sleeving mechanism and the film shrinking oven. Although the non-interference between the film sleeving work and the high-temperature film shrinking work is achieved, the structure is complex and the operation is complicated. Moreover, in order to drive the sliding seat with the claw holder to stop and move, a rotary clutch seat and a moving clutch seat need to be arranged at different positions, resulting in a complex structure, low running accuracy, and prone to running failures.

[0014] The advantages of the present invention are as follows: The cable reel on the feeding station can be transported to the labeling mechanism by the mechanical gripper for automatic labeling. After the labeling is completed, the cable reel on the mechanical gripper can be transported to the film sleeving mechanism by the transfer gripper on the integrated bracket for film sleeving. After the film sleeving is completed, the transfer gripper can transport the cable reel with the packaging film sleeved thereon to the wire reel claw of the conveying mechanism. Then, the conveying mechanism transports the cable reel with the packaging film sleeved thereon to the shrink film oven for high-temperature shrink film through the wire reel claw. After the high-temperature shrink film is completed, the cable reel can be sent to the air-cooling mechanism for air-cooling while being transported, and finally taken down by the material taking manipulator.

The conveying mechanism in this application is surrounded by four belt conveyors connected end to end, and the belt conveyor drives the wire reel claw to transport the cable reel. Clutch seats are respectively arranged at the feeding position and the discharging position of the conveying mechanism, so that the wire reel claw can stop running to realize feeding or discharging under the condition that the conveying mechanism does not stop, thus not affecting other processes. After the cable reel is placed on the receiving seat in the wire reel claw, the clamping arms in the semi-clamping state rotate to the clamping state by the self-weight of the cable reel to clamp the cable reel. The clamping speed is fast and the stability is high. Compared with the automatic film covering machine for blasting cable reels with the publication number of CN117048911B, the conveying mechanism in this application has a simple structure, high running accuracy and low failure rate.

[0027] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings and preferred embodiments.

[0028] Such as Figures 1 to 12As shown in the figure, the full-automatic cable reel film covering equipment of the present invention includes: an integrated bracket 1 and a conveying mechanism 2. The integrated bracket 1 is located on the front side of the conveying mechanism 2. A labeling mechanism 11 capable of labeling the cable reel, a film feeding mechanism 13 capable of feeding the packaging film to the film sleeving mechanism 12, and a film sleeving mechanism 12 capable of sleeving the packaging film on the cable reel are provided on the integrated bracket 1. The labeling mechanism 11 is a prior art, only installed on the integrated bracket 1. The working principle and structure of the labeling mechanism 11 will not be elaborated here. The film sleeving mechanism 12 includes: a connecting plate 121 connected to the integrated bracket 1. A film guiding servo slide 1211 is vertically arranged on the connecting plate 121. A film guiding and film clamping assembly 122 is arranged on the film guiding servo slide 1211. A film guiding roller 123, a film clamping and film combing assembly 124, and a film cutting assembly 125 are sequentially arranged on the connecting plate 121 from top to bottom. Two guide plates 126 are connected between the film clamping and film combing assembly 124 and the film cutting assembly 125. A lifting seat 1261 is slidably arranged up and down between the two guide plates 126. A film pulling assembly 127 is rotatably arranged on the lifting seat 1261. The film pulling assembly 127 is vertically aligned with the film guiding and film clamping assembly 122. A heat-sealing film assembly 128 is arranged on any one of the guide plates 126. After the packaging film roll is sleeved on the film feeding mechanism 13, the packaging film extends out and winds around the film guiding roller 123, and then extends downward from the film guiding roller 123 into the film clamping and film combing assembly 124 and extends downward for a certain length. At this time, the film cutting assembly 125 is in an open state. Then the lifting seat 1261 drives the film pulling assembly 127 to move upward, and successively passes over the open film guiding and film clamping assembly 122 and the film cutting assembly 125 from bottom to top and clamps the packaging film extending out of the film clamping and film combing assembly 122. Then the lifting seat 1261 drives the film pulling assembly 127 and the packaging film to move downward together. When the film pulling assembly 127 moves downward to be below the film guiding and film clamping assembly 122, the film guiding and film clamping assembly 122 semi-clamps the packaging film. Then the film cutting assembly 125 is started, and the film cutting assembly 125 cuts off the packaging film. The lifting seat 1261 drives the film pulling assembly 127 and the packaging film to continue to move downward. Since the film guiding and film clamping assembly 122 semi-clamps the packaging film, the packaging film can move downward in the film guiding and film clamping assembly 122. When the film pulling assembly 127 moves downward in place, the film guiding and film clamping assembly 122 fully clamps the packaging film. At this time, the packaging film is vertically straightened by the film guiding and film clamping assembly 122 and the film pulling assembly 127 for use. The detailed structure and specific working process of the film feeding mechanism 13 and the film sleeving mechanism 12 in this application can refer to the automatic film covering machine for blasting cable reels with the publication number: CN117048911B.

[0029] A mechanical gripper 3 capable of transporting a cable reel to a labeling mechanism 11 for labeling is provided on the right side of the integrated bracket 1. The mechanical gripper 3 includes: a ground rail 31, on which a servo slide 32 is provided. On the slide table of the servo slide 32, a first robotic arm 33 is provided. At the top of the first robotic arm 33, a first rotating head 331 is provided. On the first rotating head 331, a chuck seat 34 is provided. On the chuck seat 34, a first four-jaw pneumatic chuck 35 is provided. On the outer side walls of the four first jaws 351 of the first four-jaw pneumatic chuck 35, first buffer rubber pads 352 and first limit top blocks 353 are provided. The servo slide 32 drives the first robotic arm 33 to move back and forth. The cable reel wound by the winding machine is placed on the loading station. The servo slide 32 drives the first robotic arm 33 to move forward close to the cable reel on the loading station. The first robotic arm 33 drives the first four-jaw pneumatic chuck 35 to approach the cable reel vertically downward. The four first jaws 351 on the first four-jaw pneumatic chuck 35 extend into the cable reel. When the first limit top blocks 353 on the four first jaws 351 abut against the cable reel, the first four-jaw pneumatic chuck 35 drives the four first jaws 351 to open outward. The first buffer rubber pads 352 on the four first jaws 351 support on the inner wall of the cable reel, which not only plays a role in transporting the cable reel but also prevents wear on the cable sheath. Then, the servo slide 32 drives the first robotic arm 33 to move backward to the right side of the integrated bracket 1. The first robotic arm 33 drives the first four-jaw pneumatic chuck 35 to send the cable reel to the labeling mechanism 11 for labeling.

[0030] An adapter gripper 4 is further provided on the integrated bracket 1, which can transfer the cable reel with labels affixed on the mechanical gripper 3 to the film sleeving mechanism 12 for film sleeving and then transfer it to the conveying mechanism 2. The adapter gripper 4 includes: a servo cross slide 41 fixed on the integrated bracket 1, an installation plate 42 is arranged on the slide base of the servo cross slide 41, a turntable 43 is rotatably arranged on the installation plate 42, a servo motor 44 connected to the turntable 43 is arranged on the installation plate 42, a rotating plate 45 is connected to the turntable 43, a slide plate 46 is horizontally slidably arranged on the rotating plate 45, a second four-jaw pneumatic chuck 47 is arranged on the slide plate 46, second buffer rubber pads 472 and second limit top blocks 473 are arranged on the outer side walls of the four second jaws 471 of the second four-jaw pneumatic chuck 47, a horizontal cylinder 48 connected to the slide plate 46 is arranged on the rotating plate 45. When the adapter gripper 4 receives the cable reel on the mechanical gripper 3, the four second jaws 471 on the second four-jaw pneumatic chuck 47 are misaligned with the four first jaws 351 on the first four-jaw pneumatic chuck 35.When the cable reel is being labeled, the servo motor 44 in the transfer gripper 4 drives the turntable 43 and the turntable 45 to rotate until the second four-jaw pneumatic chuck 47 on the turntable 45 faces forward. The first robotic arm 33 in the mechanical gripper 3 drives the first four-jaw pneumatic chuck 35 to be horizontal, that is, the cable reel is in a vertical state. The first robotic arm 33 drives the first four-jaw chuck 35 to rotate horizontally until it is aligned with the second four-jaw pneumatic chuck 47 front and back. The first robotic arm 33 drives the first four-jaw chuck 35 to move backward, transporting the cable reel onto the second four-jaw pneumatic chuck 47. The four second jaws 471 on the second four-jaw pneumatic chuck 47 are misaligned with the four first jaws 351 on the first four-jaw pneumatic chuck 35, so that the second four-jaw pneumatic chuck 47 and the first four-jaw pneumatic chuck 35 will not interfere. When the cable reel abuts against the second limit top block 473 on the second jaw 471, the second four-jaw pneumatic chuck 47 drives the four second jaws 471 to open outward. The second buffer rubber pads 472 on the four second jaws 471 support against the inner wall of the cable reel. The four first jaws 351 on the first four-jaw pneumatic chuck 35 contract, and the first robotic arm 33 drives the first four-jaw pneumatic chuck 35 to reset. The servo motor 44 drives the turntable 43 and the turntable 45 to rotate until the second four-jaw pneumatic chuck 47 on the turntable 45 rotates to face left. The servo cross slide 41 drives the second four-jaw pneumatic chuck 47 to move horizontally back and forth until it is aligned left and right with the packaging film vertically straightened by the film guiding and clamping assembly 122 and the film pulling assembly 127 in the film sleeving mechanism 12. Then the horizontal cylinder 48 pushes the slide plate 46 and the second four-jaw pneumatic chuck 47 to move left. When the cable reel on the second four-jaw pneumatic chuck 47 contacts the straightened packaging film, the film guiding and clamping assembly 122 moves downward, and the film pulling assembly 127 moves upward. When the film guiding and clamping assembly 122 and the film pulling assembly 127 come into contact, the packaging films in both are butted, and the packaging film can be wrapped around the cable reel in a cylindrical shape. Then the lifting seat 1261 drives the film pulling assembly 127 to rotate away from the heat sealing film assembly 128. The heat sealing film assembly 128 abuts against the butting portion of the packaging film to heat seal the packaging film, and the packaging film is wrapped around the cable reel in a cylindrical shape. Since the transfer gripper 4 is all automatically controlled with high operating precision and can accurately control the clamping position and conveying position of the cable reel, the cable reel can be stably conveyed to the central position of the straightened packaging film. Thus, when the packaging film is wrapped around the cable reel in a cylindrical shape, the lengths of both ends of the packaging film extending beyond the cable reel are the same, so there is no need to additionally set a film positioning mechanism like the automatic film sleeving machine for blasting cable reels with the publication number: CN117048911B.After the film sleeving is completed, the horizontal cylinder 48 drives the slide plate 46 and the second four-jaw pneumatic chuck 47 to reset horizontally to the right. The servo motor 44 in the transfer gripper 4 drives the turntable 43 to drive the turntable 45 and the second four-jaw pneumatic chuck 47 to rotate backward. The servo cross slide 41 transports the cable reel with the packaging film sleeved thereon on the second four-jaw pneumatic chuck 47 to the rear conveying mechanism 2. Since the docking position on the packaging film is fixed when the film sleeving mechanism 12 sleeves the packaging film on the cable reel, when the cable reel with the packaging film sleeved thereon is transported to the conveying mechanism 2, the docking position on the packaging film remains unchanged.

[0031] Four belt conveying lines 21 connected end to end are horizontally arranged around in the conveying mechanism 2. A number of coil chucks 5 that can be transported by the belt conveying lines 21 are movably arranged in the conveying mechanism 2. The coil chuck 5 includes: a support plate 51. Extension parts 511 are respectively extended at the front and rear ends of the support plate 51. The extension parts 511 extend out of the belt conveying line 21. Two T-shaped guide holes 512 are symmetrically arranged at the left and right ends of the extension parts 511. Two rotating wheels 52 are rotatably arranged at the left and right ends of the bottom wall of the support plate 51. The flat bottom wall of the rotating wheel 52 abuts against the conveyor belt 211 of the belt conveying line 21. The circumferential side wall of the rotating wheel 52 abuts against the baffles 212 on both sides of the belt conveying line 21. When the conveyor belt 211 runs, it will pull the rotating wheel 52 to run together through friction. When the rotating wheel 52 contacts the baffle 212 during the running process, the rotating wheel 52 rotates. The baffle 212 not only plays a guiding role but also does not interfere with the running of the rotating wheel 52. When the rotating wheel 52 runs, it can drive the support plate 51 to move together. When the support plate 51 moves to the end of a belt conveying line 21, the first rotating wheel 52 on the support plate 51 will disengage from the conveyor belt 211 on this belt conveying line 21 and contact the conveyor belt 211 at the head of the adjacent belt conveying line 21. The conveyor belt 211 on the adjacent belt conveying line 21 will drive the first rotating wheel 52 to run in the reverse direction. And the second rotating wheel 52 on the support plate 51 will continue to run in the original direction under the push of the conveyor belt 211 on the original belt conveying line 21 until the second rotating wheel 52 also moves to the end of the belt conveying line 21 and disengages from the conveyor belt 211 on this belt conveying line 21. When the second rotating wheel 52 also contacts the conveyor belt 211 on the adjacent belt conveying line 21, both rotating wheels 52 on the support plate 51 enter the adjacent belt conveying line 21 to run, and the support plate 51 completes a right-angle turn.

[0032] An installation seat 53 is provided on the support plate 51. A receiving seat 54 is slidably arranged up and down in the installation seat 53. A number of universal ball bearings 541 are provided on the peripheral side walls of the receiving seat 54. The universal ball bearings 541 abut against the installation seat 53. Limiting long grooves 542 are vertically opened on the front and rear side walls of the receiving seat 54. Limiting bolts 531 are threadedly connected to the front and rear side walls of the installation seat 53 respectively. The limiting bolts 531 extend into the corresponding limiting long grooves 542. Two load-bearing springs 55 are symmetrically arranged between the receiving seat 54 and the installation seat 53. The receiving seat 54 is used to receive the cable reel sleeved with the packaging film and send it into the shrink film oven 24 for high-temperature shrink film. In order to prevent the packaging film from adhering to the receiving seat 54 during high-temperature shrink film, the receiving seat 54 is made of synthetic stone with high temperature resistance and low thermal conductivity. In this way, the surface temperature of the receiving seat 54 is relatively low in a high-temperature environment and will not damage the packaging film. And the receiving seat 54 made of synthetic stone is relatively heavy. When the receiving seat 54 abuts against the two load-bearing springs 55, the two load-bearing springs 55 will be compressed due to its own weight. The load-bearing springs 55 play a role in supporting and buffering the receiving seat 54. The setting of the universal ball bearings 541 between the receiving seat 54 and the installation seat 53 can reduce the friction between the receiving seat 54 and the installation seat 53 and improve the sliding response speed of the receiving seat 54. The cooperation between the limiting long grooves 542 and the limiting bolts 531 can limit the up and down sliding range of the receiving seat 54. Two inclined arms 543 are symmetrically arranged at the left and right ends of the receiving seat 54. Limiting convex blocks 544 are provided on the front and rear side walls of the inclined arms 543. Two hinge grooves are symmetrically arranged at the left and right ends of the installation seat 53. A clamping arm 56 is rotatably arranged on each of the two groove walls of the hinge groove. A gap is left between the two clamping arms 56 located in the same hinge groove. The two limiting convex blocks 544 on the inclined arms 543 abut against the two clamping arms 56 in the same-side hinge groove, forcing the two clamping arms 56 on both sides to rotate and close to be in a semi-clamping state. A synchronous plate 561 is connected between the two clamping arms 56 located in the same hinge groove. Through the synchronous plate 561, the two clamping arms 56 can rotate synchronously. A spring seat 532 is symmetrically arranged at the left and right ends of the installation seat 53. Two spring columns are provided on the spring seat 532. The two spring columns are respectively aligned with the two clamping arms 56 on the same side. A side spring 533 is sleeved on the spring column. The side spring 533 abuts against the aligned clamping arm 56. When there is no cable reel placed on the receiving seat 54, the two clamping arms 56 on both sides rotate and close to form a semi-clamping state under the dual action of the downward pressure of the limiting convex blocks 544 on the receiving seat 54 and the pushing of the side spring 533. After the cable reel is placed between the two inclined arms 543 of the receiving seat 54, the cable reel forces the receiving seat 54 to continue to slide downward due to its own weight. The limiting convex blocks 544 on the two inclined arms 543 of the receiving seat 54 continue to press down the clamping arms 56 on the same side, causing the clamping arms 56 to rotate and close against the elastic force of the side spring 533. The two clamping arms 56 on both sides will clamp on the cable reel.

[0033] When the clamping arms 56 on both sides are in a semi-clamped state, the cable reel cannot pass through the clamping arms 56 on both sides smoothly and be placed on the receiving seat 54, which will cause displacement or dropping of the packaging film on the cable reel. Therefore, at least one side of the clamping arm 56 needs to be rotated and opened before the cable reel can be placed. A pull rod 57 is slidably arranged left and right on the mounting seat 53, and an inclined ejector block 571 extends downward on the pull rod 57. The pull rod 57 is hinged to any one of the synchronizing plates 561. The connection structure between the pull rod 57, the mounting seat 53 and the synchronizing plate 561 is as follows: Hinge plates 562 are arranged on both synchronizing plates 561, threaded holes are arranged on the hinge plates 562, connection holes 572 and long guide holes 573 are respectively arranged at the left and right ends of the pull rod 57. After the connection hole 572 on the pull rod 57 is aligned with the threaded hole on one hinge plate 562, a bolt is threadedly connected, and the connection hole 572 on the pull rod 57 is rotatably matched with the bolt. An internal hexagonal bolt is threadedly connected to the threaded hole on the other hinge plate 562, and the long guide hole 573 on the pull rod 57 is sleeved on the internal hexagonal bolt. An L-shaped limiting plate 534 is arranged on the mounting seat 53, and the L-shaped limiting plate 534 abuts against the pull rod 57 to play a role of limiting and guiding the pull rod 57. Applying a force to the inclined ejector block 571 on the pull rod 57 in the direction of the long guide hole 573 can push the pull rod 57 to move horizontally along the L-shaped limiting plate 534 and the internal hexagonal bolt in the direction of the long guide hole 573. The pull rod 57 controls the hinge plate 562 through the bolt to drive the clamping arm 56 connected to the hinge plate 562 to rotate and open together. When the clamping arm 56 on this side is opened, the width between the clamping arms 56 on both sides of the mounting seat 53 is sufficient to accommodate the cable reel, and the transfer gripper 4 can place the cable reel with the packaging film on the receiving seat 54. The clamping arm 56 that is not pulled open by the pull rod 57 will first abut against one side wall of the cable reel to prevent the cable reel from dropping. After no force is applied to the pull rod 57, the opened clamping arm 56 will abut against the other side wall of the cable reel under the pressing action of the limiting convex block 544 on the same side. The clamping arms 56 on both sides of the mounting seat 53 and the inclined arms 543 on the receiving seat 54 can cooperate to clamp the cable reel.

[0034] In order to enable the clamping arm 56 connected to the pull rod 57 to open automatically, an opener 22 capable of pushing open the coil gripper 5 is provided on the front belt conveyor 21. The opener 22 includes: an opening and closing cylinder 221, which is obliquely fixed on the front belt conveyor 21. An opening and closing plate 222 is provided on the piston rod of the opening and closing cylinder 221. An opening and closing shaft 223 is provided on the opening and closing plate 222, and a rubber ring pad 224 is provided on the opening and closing shaft 223. When the coil gripper 5 moves to the front belt conveyor 21, the opening and closing cylinder 221 in the opener 22 drives the opening and closing plate 222 and the opening and closing shaft 223 to extend towards the pull rod 57. The rubber ring pad 224 on the opening and closing shaft 223 pushes against the inclined top block 571 of the pull rod 57, forcing the pull rod 57 to slide horizontally towards the elongated guide hole 573, causing one side of the clamping arm 56 to rotate and open, thus achieving automatic opening. Then, in cooperation with the transfer gripper 4, the automatic feeding function can be realized. The rubber ring pad 224 is provided on the opening and closing shaft 223 and the inclined top block 571 is pushed and pulled through the rubber ring pad 224 to prevent noise reduction and prevent a large noise from occurring when the opening and closing shaft 223 comes into contact with the inclined top block 571.

[0035] Since the conveyor belt 211 in the belt conveyor line 21 is always in operation, a clutch 23 capable of pushing the coil gripper 5 upward to disengage from the belt conveyor line 21 needs to be provided on the front belt conveyor line 21. After the coil gripper 5 disengages from the belt conveyor line 21 upward, it stays on the clutch 23, facilitating the opener 22 to open the coil gripper 5. The clutch 23 includes: a double-axis lifting cylinder 231 and a limit plate 232. A cylinder seat 233 is vertically provided on both side baffles of the belt conveyor line 21. The limit plate 232 and the double-axis lifting cylinder 231 are respectively arranged on the cylinder seat 233 and are located on the upper and lower sides of the support plate 51. A guide plate 234 is provided on the double-axis lifting cylinder 231. Two T-shaped guide shafts 235 are symmetrically arranged on the left and right sides of the guide plate 234. The two T-shaped guide shafts 235 are respectively coaxially aligned with two T-shaped guide holes 512 on the same-side extension part 511 up and down. Two positioning sleeves 236 are symmetrically arranged on the limit plate 232. When the double-axis lifting cylinder 231 drives the guide plate 234 to rise, the two T-shaped guide shafts 235 on the guide plate 234 are inserted into the two T-shaped guide holes 512 on the same side to stop the coil gripper 5, and then continue to lift. The guide plate 234 abuts against the support plate 51 to lift the coil gripper 5 upward. The two positioning sleeves 236 on the limit plate 232 cooperate with the guide plate 234 to clamp and fix the support plate 51. The two runners 52 on the support plate 51 disengage from the conveyor belt 211 in the belt conveyor line 21, and the coil gripper 5 stays on the clutch 23, facilitating the opener 22 to open the coil gripper 5. After the coil gripper 5 completes automatic feeding in cooperation with the transfer gripper 4, the double-axis lifting cylinder 231 drives the guide plate 234 to reset downward, and the coil gripper 5 falls back onto the conveyor belt 211 in the belt conveyor line 21 again. After the T-shaped guide shafts 235 on the guide plate 234 disengage from the support plate 51, the coil gripper 5 can run in the belt conveyor line 21 again.

[0036] A shrink film oven 24 is provided on the left belt conveyor line 21. A channel penetrating the front and rear end walls of the shrink film oven 24 is provided in the shrink film oven 24. The left belt conveyor line 21 is located in the channel of the shrink film oven 24. When the coil gripper 5 holding the cable reel sleeved with the packaging film enters the shrink film oven 24, the packaging film will shrink and tightly wrap around the cable reel at high temperature. A first gear shifting cylinder 25 is vertically provided on the front belt conveyor line 21. The first gear shifting cylinder 25 is located on the left side of the clutch 23 of the front belt conveyor line 21. A first gear lever 251 is provided on the piston rod of the first gear shifting cylinder 25. After the previous coil gripper 5 enters the shrink film oven 24, the first gear shifting cylinder 25 drives the first gear lever 251 to rise, and the support plate 51 in the latter coil gripper 5 will be blocked by the first gear lever 251 and will no longer move into the shrink film oven 24, thereby controlling the running distance between the two coil grippers 5.

[0037] There are two flat seam mechanisms 26 symmetrically arranged on the belt conveyor line 21 at the rear section of the shrink film oven 24. The flat seam mechanism 26 includes: a vertical seat 261 which is fixed on the left belt conveyor line 21. A pneumatic slide 262 is horizontally arranged on the vertical seat 261. A heating plate support 263 is arranged on the pneumatic slide 262. An electric heating plate 2631 is arranged on the side wall of the heating plate support 263 facing the conveyor belt 211 on the belt conveyor line 21. A translation cylinder 264 facing the shrink film oven 24 is arranged on the heating plate support 263. A cylinder plate 2641 is arranged on the translation cylinder 264. A needle cylinder 265 is arranged on the cylinder plate 2641. A copper clamping plate 2651 facing the belt conveyor line 21 is arranged on the needle cylinder 265. Since there is a butt joint seam on the tubular packaging film, the packaging film will form uneven wrinkles at the butt joint seam during shrink film wrapping. Since the position of the butt joint seam of the packaging film on each cable reel is fixed, the flat seam mechanism 26 can iron out the wrinkled butt joint seam on the packaging film. Since there are wrinkled butt joint seams on both sides of the packaging film, two flat seam mechanisms 26 are required to iron out the butt joint seams on both sides of the packaging film simultaneously. A second gear cylinder 27 is vertically arranged at the rear of the flat seam mechanism 26. The second gear cylinder 27 is fixed on the left belt conveyor line 21. A second gear rod 271 is arranged on the piston rod of the second gear cylinder 27. The second gear cylinder 27 drives the second gear rod 271 to rise. When the coil gripper 5 comes out of the shrink film oven 24, the rising second gear rod 271 blocks the coil gripper 5. The pneumatic slide 262 in the flat seam mechanism 26 drives the heating plate support 263 to move towards the coil gripper 5. When the electric heating plate 2631 on the heating plate support 263 abuts against the wrinkled part on the outer side wall of the packaging film, the translation cylinder 264 drives the cylinder plate 2641 to move backward. When the copper clamping plate 2651 on the cylinder plate 2641 is inside the cable reel and flush with the wrinkled part, the copper clamping plate 2651 and the electric heating plate 2631 are respectively located on the inner and outer sides of the wrinkled part. Then the needle cylinder 265 drives the copper clamping plate 2651 to move towards the electric heating plate 2631. The copper clamping plate 2651 abuts against the wrinkled part on the inner side wall of the packaging film. The electric heating plate 2631 cooperates with the copper clamping plate 2651 to iron out the wrinkled part. After completion, the needle cylinder 265 drives the copper clamping plate 2651 away from the packaging film. The translation cylinder 264 drives the copper clamping plate 2651 to move forward. Finally, the pneumatic slide 262 drives the heating plate support 263 to move away from the cable reel. The electric heating plate 2631 and the copper clamping plate 2651 no longer interfere with the operation of the cable reel. The second gear cylinder 27 drives the second gear rod 271 to descend, and the coil gripper 5 can continue to be transported backward.

[0038] An air-cooling mechanism 6 is provided on the rear belt conveyor line 21. The air-cooling mechanism 6 includes: a mounting frame 61. One mounting frame 61 is respectively provided on the front and rear side walls of the rear belt conveyor line 21. A number of air blowers 62 are horizontally and evenly distributed along the conveying direction on the two mounting frames 61. A reinforcing plate 63 is provided between the tops of the two mounting frames 61, and a number of ventilation holes 631 are evenly distributed on the reinforcing plate 63. When the cable reel after high-temperature shrink film is conveyed by the rear belt conveyor line 21, the air blowers 62 in the air-cooling mechanism 6 perform air-cooling on the cable reel, and air-cooling is achieved simultaneously during the conveying process, which can greatly improve the cooling speed of the packaging film on the cable reel. The reinforcing plate 63 with ventilation holes 631 provided between the two mounting frames 61 can not only improve the stability between the two mounting frames 61, but also ensure the heat dissipation efficiency of the packaging film, so that the heat of the packaging film can overflow outward from the ventilation holes 631.

[0039] A clutch 23 is also provided on the belt conveyor line 21 on the right side. A material taking manipulator 7 is provided on the right side of the conveying mechanism 2. When the wire reel claw 5 is lifted by the clutch 23 on the belt conveyor line 21 on the right side, the material taking manipulator 7 can remove the cable reel on the wire reel claw 5 for stacking, completing automatic blanking. The material taking manipulator 7 includes: a machine base 71, a second robotic arm 72 is provided on the machine base 71, a second rotating head 721 is provided in the second robotic arm 72, a finger cylinder 73 is connected to the second rotating head 721, straight arms 731 are provided on both telescopic ends of the finger cylinder 73, the width of the clamping portion of the straight arm 731 is smaller than the width of the gap between the two clamping arms 56 on the same side in the wire reel claw 5, and a third buffer rubber pad 732 is provided on the clamping portion of the straight arm 731. When the wire reel claw 5 is stopped by the clutch 23 on the belt conveyor line 21 on the right side, the second robotic arm 72 drives the finger cylinder 73 to move directly above the wire reel claw 5. The two straight arms 731 on the finger cylinder 73 are respectively located on both sides of the wire reel claw 5. The finger cylinder 73 drives the two straight arms 731 to close. After the two straight arms 731 pass through the gap between the two clamping arms 56 on the same side, they clamp the cable reel. When the third buffer rubber pad 732 on the straight arm 731 comes into contact with the cable reel, it can not only prevent scratching the packaging film on the cable reel, but also enhance the friction to make the clamping more stable. Then the second robotic arm 72 drives the finger cylinder 73 to rise vertically to remove the cable reel from the wire reel claw 5, and then stacks it. When the material taking manipulator 7 removes the cable reel from the wire reel claw 5, the receiving seat 54 will rise and reset under the elastic force of the load-bearing spring 55, and the limit convex block 544 on the receiving seat 54 will rise. When the limit convex block 544 stops abutting against the clamping arm 56 on the same side, the two clamping arms 56 on both sides will rotate and open under the elastic force of the corresponding side spring 533 on the same side until they abut against the limit convex block 544 on the same side again. At this time, the two clamping arms 56 are in a semi-clamping state. The material taking manipulator 7 drives the cable reel to continue moving upward. The cable reel will squeeze the two clamping arms 56 on both sides, forcing the two clamping arms 56 on both sides to overcome the downward pressure of the limit convex block 544 and continue to rotate and open until the cable reel is taken out. When there is no cable reel between the clamping arms 56, the clamping arms 56 will return to the semi-clamping state under the downward pressure of the limit convex block 544 on the same side.

[0040] When blanking, in order to prevent other wire coil claws 5 from affecting the blanking work, a third gear cylinder 28 is vertically arranged on the right side of the air-cooling mechanism 6. The third gear cylinder 28 is fixed on the rear belt conveyor 21. A third gear rod 281 is arranged on the piston rod of the third gear cylinder 28. When the wire coil claw 5 is blanking, the third gear cylinder 28 drives the third gear rod 281 to rise to block the movement of other wire coil claws 5 on the rear belt conveyor 21, and the wire coil claw 5 blocked by the third gear rod 281 is located in the air-cooling mechanism 6, so that the packaging film on the cable coil can be further cooled. When the cable coil on the wire coil claw 5 is removed and needs to be reloaded onto the front belt conveyor 21, in order to prevent other wire coil claws 5 from affecting the loading work, a fourth gear cylinder 29 is vertically arranged on the right belt conveyor 21. The fourth gear cylinder 29 is located in front of the clutch 23 of the right belt conveyor 21. A fourth gear rod 291 is arranged on the piston rod of the fourth gear cylinder 29. When the fourth gear cylinder 29 drives the fourth lever 291 to rise, it can block the movement of other wire coil claws 5 on the right belt conveyor 21, thus not affecting the loading of the wire coil claw 5 on the front belt conveyor 21.
