[0059] like Figure 1 As shown on the operating table 410, from right to left, a long tube storage mechanism 100, a stretching bellows assembly 200 and a pressure head clamp assembly 300 are sequentially arranged. The sealing mechanism is arranged on the operating table and can slide back and forth in the vertical direction to make it close to and away from the pressure head clamp assembly 300 and the stretching bellows assembly 200. Among them, the long tube storage mechanism 100 supports the long tube to be wound, and the long tube is initially fixed by the stretching bellows assembly 200 through the stretching corrugation, and the pressure head clamp assembly 300 is used to clamp one end of the inner tube arranged inside the long tube to fix it, and the inner tube is exposed by horizontally moving the stretching bellows assembly 200, and the sealing mechanism is moved to make it close to the inner tube and wind the inner tube, and after completion, the sealing mechanism is moved again to make it away from the inner tube, and the stretching bellows assembly is moved horizontally to wrap the outer tube around the wound inner tube to complete the winding.

[0060] The long tube storage mechanism 100 is arranged on one side of the operating table 410, one end of the long tube storage mechanism 100 is arranged outside the frame 400, and the other end is arranged inside the frame 400, and supported above the operating table 410. A plurality of fixing clips are arranged along the axial direction on the long tube storage mechanism 100, which are used to connect and position the long tube. The long tube includes an inner tube and an outer tube sleeved outside the inner tube, and an electric heating wire is also arranged between the inner tube and the outer tube.

[0061] like Figure 5-6 As shown, the stretching bellows assembly 200 is located on the left side of the long tube storage mechanism 100, and specifically includes: a first clamping block 210, a second clamping block 220, a third clamping block 230, a transverse cylinder 240, and a first clamping block 250. Among them, the transverse cylinder 240 is horizontally arranged at the lower part of the stretching bellows assembly 200, so that the stretching bellows assembly can move horizontally. At the top of the stretching bellows assembly 200, the first clamping block 210, the second clamping block 220 and the third clamping block 230 are arranged from left to right in sequence. Two first clamping blocks 250 are symmetrically arranged between the first clamping block 210 and the second clamping block 220, and are respectively driven by two clamping cylinders arranged on one side of the two first clamping blocks 250.

[0062] like Figure 3-4As shown, the pressure head fixture assembly 300 is located on the left side of the stretched corrugated tube 200, and specifically includes: a lifting cylinder 310, a clamping cylinder 320, a pressure head 330, a wire clamping cylinder 340, and a second wire clamping block 350. Among them, the lifting cylinder 310 is vertically arranged at the lower part of the pressure head fixture assembly 300, so that the pressure head fixture assembly 300 can be lifted up and down, and two second wire clamping blocks 350 are symmetrically arranged at the top of the pressure head fixture assembly 300. Between the two wire clamping blocks 350, a pressure head 330 is arranged. Two wire clamping cylinders 340 are arranged at both ends of the top of the pressure head fixture assembly 300, and are used to drive the two wire clamping blocks 350 respectively. The clamping cylinder 320 is horizontally arranged above the lifting cylinder, and is used to drive the pressure head 330 to rise and fall.

[0063] During operation, first drive the lifting cylinder 310 and the clamping cylinder 320 to raise the ram clamp assembly, the operator places one end of the corrugated tube from the long tube storage mechanism 100 under the ram 330, and places the electric heating wire in the corrugated tube into the two second clamping blocks 350 in turn, then the operator manually presses down the ram 330 to clamp the corrugated tube workpiece, then the lifting cylinder 310 descends to return the ram clamp assembly 300 to its original position.

[0064] The bellows is clamped in sequence by the first clamping block 210, the second clamping block 220 and the third clamping block 230. After the clamping is completed, the transverse cylinder 240 is started, and the outer tube of the bellows is compressed by the contraction of the transverse cylinder to expose the inner tube of the bellows. At this time, the electric heater is first removed from the two second clamping blocks 350 and placed in the two first clamping blocks 250. At this time, the sealing mechanism is moved to make it close to the inner tube. After the inner tube is wrapped and sealed, the electric heating wire is removed and wrapped around the outside of the sealing tape for the second sealing. After completion, the outer tube is expanded and restored to its original position by the expansion of the transverse cylinder 240, and the inner tube that has been wrapped and sealed is wrapped. The third clamping block 230, the second clamping block 220, the first clamping block 210 and the pressure head 330 are opened in sequence, the bellows is removed, and the winding and sealing are completed.

A third driving motor 540 is arranged on the base plate 440, and its power is connected to the driving gear, which is meshed with the rack and can drive the base plate 440 to move in the vertical direction on the slide rail 420. The support plate 530 is vertically arranged on the base plate 440 and is parallel to the slide rail 420. Therefore, through the rotation of the third driving motor 540 and the cooperation of the driving gear and the rack, the reciprocating motion of the sealing mechanism can be realized, so that the sealing mechanism is close to and away from the inner tube.

The cylindrical gear 593 can rotate synchronously with the two second transmission gears 592, that is, the first driving mechanism drives the cylindrical gear 593 to rotate through the two second transmission gears 592. One side of the cylindrical gear 593 has a gear opening, and a V-shaped pressure plate 594 is arranged inside the opening, which is fixed on the inner wall of the cylindrical gear, and the opening direction is toward the gear opening. At the gear opening, two clamping supports 596 are symmetrically arranged, and pressure wheel shafts are symmetrically arranged on the two clamping supports 596, and nylon rollers are arranged on them.

The openings of the two clamping supports are close to the inner tube with the corrugated tube wrapped around them, and the sealing tape 522 is pulled downward to make it long enough to cover the openings of the two clamping supports.

The fourth transmission gear 472 needs to drive the sealing tape 522 adhered thereto to move downward, and the fifth transmission gear 473 needs to peel the sealing tape 522 off the fourth transmission gear 472, and the two have relative movement so that the sealing tape 522 will not stick.

Then, the operator manually presses down the ram 330 to clamp the bellows workpiece. Then, the lifting cylinder 310 descends to return the ram clamp assembly 300 to its original position.

[0074] The bellows is clamped in sequence by the first clamping block 210, the second clamping block 220 and the third clamping block 230. After the clamping is completed, the transverse cylinder 240 is started, and the outer tube of the bellows is compressed by the contraction of the transverse cylinder to expose the inner tube of the bellows. At this time, the electric heater is first removed from the two second clamping blocks 350 and placed in the two first clamping blocks 250. At this time, the sealing mechanism is moved to make it close to the inner tube.
