[0033] The ground assembly 1 is embedded in the ground in actual use, and after the operation such as waxing of the aluminum belt is completed, the aluminum belt is wound on the metal sleeve 8 to form an aluminum belt roll, in use, the metal sleeve 8 is placed on the upper feeding assembly 4, the upper feeding assembly 4 is started to convey the metal sleeve 8 to a position on the same axis as the output shaft 61, at this time, the mechanical arm assembly 5 is started to clamp the metal sleeve 8 on the upper feeding assembly 4, then the mechanical arm assembly 5 moves horizontally to wrap the metal sleeve 8 on the outside of the output shaft 61, the winding machine 6 drives the output shaft 61 to rotate, and the track belt after external processing is wound on the outside of the metal sleeve 8, and the winding is realized under the driving of the winding machine 6, when the winding machine 6 drives the output shaft 61 and the metal sleeve 8 to wind the aluminum belt, at this time, the conveying assembly 3 is located below the output shaft 61, and the baffle assembly 2 blocks the pit 12 to prevent the situation that people and objects fall, when the winding is completed, the supporting assembly 7 loses the limiting effect on the metal sleeve 8, then the conveying assembly 3 works to convey the wound aluminum belt roll from the output shaft 61 to a discharging position, and the discharging position is located at the end of the pit 12 away from the winding machine 6, the whole process realizes high automation, and the crane is not needed for discharging and feeding, thereby realizing high automation and rapid feeding and discharging.

[0034] When the metal sleeve 8 is sleeved outside the output shaft 61, at this time the hydraulic cylinder drives the blocking arm 72 to rotate and abuts the end of the output shaft 61, the rotating rod 73 can not hinder the rotation of the output shaft 61, prevents the metal sleeve 8 and the aluminum belt roll thereon from tilting and falling during the rotation of the output shaft 61, and ensures the stability of the winding.

[0035] The baffle assembly 2 comprises a first supporting plate 21, the inside of the first supporting plate 21 is slidably installed with a second supporting plate 22, the inside of the second supporting plate 22 is slidably installed with a third supporting plate 23, the inside of the third supporting plate 23 is slidably installed with a fourth supporting plate 24, the lower end of one end of the first supporting plate 21 is fixedly installed with a first baffle 211, the end of the first supporting plate 21 away from the first baffle 211 is fixedly installed inside the pit 12, the position corresponding to the first baffle 211 of the second supporting plate 22 is fixedly installed with a second baffle 221, the position corresponding to the second baffle 221 of the third supporting plate 23 is fixedly installed with a third baffle 231, the position corresponding to the third baffle 231 of the fourth supporting plate 24 is fixedly installed with a fourth baffle 241, the upper end of the end of the second supporting plate 22 away from the second baffle 221 is fixedly installed with a first clamping plate 222, the upper end of the end of the third supporting plate 23 away from the third baffle 231 is fixedly installed with a second clamping plate 232, the upper end of the end of the fourth supporting plate 24 away from the fourth baffle 241 is fixedly installed with a third clamping plate 242, the end of the first supporting plate 21, the second supporting plate 22, the third supporting plate 23 and the fourth supporting plate 24 close to the first baffle 211 are all fixedly installed with a stopper 212, two mutually symmetrical slide rails 121 are fixedly installed at the middle position inside the pit 12, two mutually symmetrical slide ways 13 are arranged at the opening position of the upper end of the pit 12, a plurality of uniformly distributed rollers 131 are rotatably installed inside the slide way 13, and the two ends of the first supporting plate 21, the second supporting plate 22, the third supporting plate 23 and the fourth supporting plate 24 are respectively located inside the two slide ways 13.

[0036] When the conveying assembly 3 gradually approaches the winding machine 6, at this time the conveying assembly 3 pulls the fourth supporting plate 24 to move, as the fourth supporting plate 24 gradually moves, the third clamping plate 242 contacts the third baffle 231, and then when the fourth supporting plate 24 is continuously pulled, the third clamping plate 242 drives the third baffle 231 and the third supporting plate 23 to move, under the continuous movement of the fourth supporting plate 24, the second clamping plate 232 drives the second baffle 221 and the second supporting plate 22 to move, until the first clamping plate 222 contacts the first baffle 211, at this time the baffle assembly 2 is unfolded to the maximum state, and the conveying assembly 3 also moves to the lower side of the output shaft 61, a plurality of rollers 131 are arranged to make the movement of the first supporting plate 21, the second supporting plate 22, the third supporting plate 23 and the fourth supporting plate 24 more smooth;

[0037] When the conveying assembly 3 moves from below the output shaft 61 to the unloading position, at this time the conveying assembly 3 pushes the fourth supporting plate 24 to move, when the fourth supporting plate 24 completely enters the inside of the third supporting plate 23, at this time the stop block 212 on the fourth supporting plate 24 drives the third supporting plate 23 to move, when the third supporting plate 23 completely enters the inside of the second supporting plate 22, the stop block 212 on the third supporting plate 23 pushes the second supporting plate 22 to move into the inside of the first supporting plate 21, thereby realizing the contraction of the baffle assembly 2 as a whole, because when the conveying assembly 3 moves below the output shaft 61, at this time the winding machine 6 drives the output shaft 61 to work, and the winding process is relatively long in time, if there is no baffle assembly 2, the pit 12 is exposed for a long time, which is easy to cause the worker to fall into the pit or other accidents, so when the winding work is carried out, the baffle assembly 2 will close the pit 12 to prevent accidents, and when the conveying assembly 3 gradually moves to the unloading position, the place exposed outside the pit 12 is blocked by the feeding assembly 4, the mechanical arm assembly 5, the winding machine 6 and the supporting assembly 7, so that the worker will not unintentionally enter, and the unloading time is relatively short, the accident is less likely to occur, and the baffle assembly 2 is not needed to block,

[0038] The conveying assembly 3 comprises a moving shell 31, a plurality of moving wheels 32 are uniformly distributed and rotatably installed on the moving shell 31, the moving wheels 32 are connected in cooperation with the slide rails 121, a U-shaped supporting plate 33 for lifting the aluminum strip coil is arranged above the moving shell 31, a guide rod 331 is fixedly installed on the lower surface of the U-shaped supporting plate 33 and slides and is clamped in the inside of the moving shell 31, a first air cylinder 34 is fixedly installed at the bottom end of the moving shell 31, the telescopic end of the first air cylinder 34 penetrates through the moving shell 31 and is fixedly installed on the U-shaped supporting plate 33, a driving mechanism 341 for driving the moving wheels 32 to rotate is fixedly installed at one end of the moving shell 31, a plurality of first blocking rods 35 are fixedly installed at one end of the moving shell 31 close to the baffle assembly 2, a second blocking rod 351 is fixedly installed on the side of the first blocking rod 35 away from the moving shell 31, and a gap exists between the first blocking rod 35 and the second blocking rod 351, and the fourth baffle 241 is located in the gap.

[0039] When the winding work is completed, at this time the first cylinder 34 works to push the U-shaped supporting plate 33 to rise, the U-shaped supporting plate 33 will support the wound aluminum strip roll to be lifted, the aluminum strip roll is lifted to lose the connection with the output shaft 61, and then the first cylinder 34 drives the moving wheel 32 to rotate and move along the slide rail 121, so that the aluminum strip roll is transported to the discharging position. The aluminum strip roll can be transported away by using a forklift or other transportation components. The guide rod 331 is used to stabilize the U-shaped supporting plate 33, so that the U-shaped supporting plate 33 always remains in a horizontal state and stably rises and falls, and the aluminum strip roll is prevented from shaking. When the transport assembly 3 drives the baffle assembly 2 to expand, at this time the second baffle 351 pulls the fourth baffle 241 to move. When the transport assembly 3 drives the baffle assembly 2 to contract, at this time the second baffle 351 gradually contacts the fourth supporting plate 24, the third supporting plate 23, the second supporting plate 22 and the first supporting plate 21, and simultaneously drives all the fourth supporting plate 24, the third supporting plate 23, the second supporting plate 22 and the first supporting plate 21 to contract synchronously, so that the disconnection is prevented.

[0040] The feeding assembly 4 comprises a sliding frame 41 fixedly installed on the floor 11. The inside of the sliding frame 41 is slidably clamped with a moving frame 42 for supporting the metal sleeve 8. A third cylinder 411 is fixedly connected between the sliding frame 41 and the moving frame 42. The upper surface of the moving frame 42 is fixedly installed with a feeding baffle 421 perpendicular to itself. The sliding frame 41 is designed to be inclined. The height of the end of the sliding frame 41 close to the pit 12 is higher than the height of the end of the sliding frame 41 away from the pit 12.

[0041] When feeding is needed, the metal sleeve 8 is placed on the moving frame 42. Because the moving frame 42 is inclined, the metal sleeve 8 will finally be supported by the feeding baffle 421. At this time, the third cylinder 411 is started, the third cylinder 411 drives the moving frame 42 to move, so that the metal sleeve 8 is located on the same axis as the output shaft 61, and the mechanical arm assembly 5 is convenient for clamping. After the metal sleeve 8 is clamped by the mechanical arm assembly 5, the third cylinder 411 drives the moving frame 42 to retract.

[0042] The mechanical arm assembly 5 comprises a support base plate 51 fixedly installed on the floor 11, a sliding support 511 slidingly installed on the upper surface of the support base plate 51, a first support arm 52 fixedly installed on the upper surface of the sliding support 511, a second support arm 53 rotatably installed at the top end of the first support arm 52, a fourth cylinder 512 fixedly installed on the sliding support 511, a driving end of the fourth cylinder 512 rotatably installed on the second support arm 53, two symmetrical clamps 54 rotatably installed at the end of the second support arm 53 away from the first support arm 52, a plurality of uniformly distributed sliding rods 541 rotatably installed on the side of the two clamps 54 close to each other, a center connecting rod 542 arranged between the two clamps 54, the plurality of sliding rods 541 rotatably connected to the center connecting rod 542, a fifth cylinder 543 fixedly installed in the second support arm 53, a telescopic end of the fifth cylinder 543 fixedly installed on the center connecting rod 542, a second cylinder 55 fixedly connected between the first support arm 52 and the floor 11, rubber blocks 544 fixedly installed on the end of the side of the two clamps 54 close to each other, the rubber blocks 544 are arc-shaped and have anti-skid grooves uniformly distributed on the surfaces.

[0043] When the material needs to be loaded, the fourth cylinder 512 works to drive the second support arm 53 to descend, the second support arm 53 is driven to descend to be horizontal, at this time the third cylinder 411 pushes the moving frame 42 to transport the metal sleeve 8 to between the two clamps 54, then the fifth cylinder 543 is started, the fifth cylinder 543 pulls the center connecting rod 542 to move, because the sliding rods 541 are rotatably connected to the clamps 54 and the center connecting rod 542, so when the center connecting rod 542 descends, it will drive the two clamps 54 to move close to each other, and then the clamps 54 will clamp the metal sleeve 8, then the third cylinder 411 pulls the moving frame 42 to return to the original position, then the second cylinder 55 pulls the first support arm 52 to move along the support base plate 51 to sleeve the metal sleeve 8 on the surface of the output shaft 61, then the second cylinder 55 pushes the first support arm 52 to reset, the fifth cylinder 543 pushes the center connecting rod 542 to make the two clamps 54 open, the rubber blocks 544 can prevent the clamps 54 from deforming the metal sleeve 8, and also can prevent the metal sleeve 8 from sliding.

[0044] The above merely provides the preferred embodiments of the present application; however, the protection scope of the present application is not limited to this.
