Since the telescopic arm 2 extends outward, in order to balance the overall structure, two balancing legs 4 are provided below the telescopic arm 2, and the balancing legs 4 are connected to the vertical welding frame 1.

[0027] like Figure 2As shown, the polyethylene tape adhesion device 3 includes a back plate 301, which is welded to the front end of the telescopic arm 2, a support plate 302 is welded to the bottom of the back plate 301, a slide plate 303 that moves forward and backward is connected to the top of the support plate 302, a vertical plate 304 is welded to the end of the slide plate 303 close to the back plate 301, and a vertically arranged first telescopic cylinder 305 is provided at the end of the slide plate 303 away from the back plate 301. The first telescopic cylinder 305 can specifically be a double-linked cylinder. The body of the first telescopic cylinder 305 is fixed on the slide plate 303, and a motor seat 306 is provided at the telescopic end of the first telescopic cylinder 305, and a horizontally arranged servo motor 307 is installed on the motor seat 306, and a swing arm 308 is provided on the driving shaft of the servo motor 307. A roller 309 with a horizontal axis is provided at the upper end of the swing arm 308, and the roller 309 rotates around its own axis. Two clamping fingers 310 are provided above the roller 309, and the clamping fingers 310 are connected to the movable end of the thumb cylinder 311, and the thumb cylinder 311 is fixed to the vertical plate 304 by bolts.

[0028] In this embodiment, the movement of the slide plate 303 is driven by the second telescopic cylinder 312, and the second telescopic cylinder 312 is specifically a triple cylinder. The second telescopic cylinder 312 is installed on the top of the back plate 301, and the telescopic end of the second telescopic cylinder 312 is connected to the vertical plate 304. The slide plate 303 is connected to the support plate 302 through the first slide rail slider structure 313. The first slide rail slider structure 313 includes two slide rails, each of which is provided with two sliders. The slide rails are fixed on the support plate 302, and the sliders are fixed to the bottom surface of the slide plate 303.

[0029] like Figure 3 and 4 As shown, a side panel 101 is provided on one side of the vertical welding frame 1, and the outer side of the side panel 101 is connected to the telescopic arm 2, and the back side of the side panel 101 is connected to the vertical welding frame 1 by sliding up and down through the second slide rail slider structure 102 on both sides, and a lifting seat 103 is provided in the middle of the back side of the side panel 101, and the lifting seat 103 is connected to the vertically arranged screw rod 104 through a thread, and the two ends of the screw rod 104 are rotatably connected to the screw rod seat 105 respectively, wherein the top end of the screw rod 104 is connected to the lifting motor 106 for power, and the screw rod seat 105 and the lifting motor 106 are both installed and fixed on the vertical welding frame 1.

[0030] It should be noted that the second slide rail slider structure 102 includes a single slide rail and a slider sliding along the slide rail. The slide rail is fixed on the vertical welding frame 1 and is slidably mounted and fixed to the side plate 101 .

[0031] like Figure 5As shown, the telescopic arm 2 includes an L-shaped bracket 201, the vertical portion of the L-shaped bracket 201 is fixedly mounted on the side plate 101, the horizontal portion of the L-shaped bracket 201 is provided with a telescopic frame 202 and a hydraulic cylinder 204 for driving the telescopic frame 202 to slide along the slide rod 203, and the front end of the telescopic frame 202 is connected to the back plate 301.

[0032] In order to balance the force on the telescopic frame 202, the telescopic frame 202 is designed to be door-shaped. There are two sliding rods 203, which are respectively located on both sides of the telescopic frame 202. The hydraulic cylinder 204 is located in the middle of the telescopic frame 202. The main body of the hydraulic cylinder 204 is fixed on the L-shaped bracket 201, and the telescopic end is connected to the telescopic frame 202.

[0035] When the polyethylene tape 7 is extruded from the extruder 5, the polyethylene tape clinging device 3 moves to the extruder 5 position under the action of the hydraulic cylinder 204, and the thumb cylinder 311 drives the two clamping fingers 310 to clamp the polyethylene tape 7. Then, the hydraulic cylinder 204 retracts, and the two clamping fingers 310 pull the polyethylene tape 7 backwards.

[0036] The lifting motor 106 drives the polyethylene tape adhesion device 3 to rise, and the polyethylene tape 7 is stretched to one side of the insulation pipe 6 under the action of the two clamping fingers 310. The first telescopic cylinder 305 extends upward, and the servo motor 307 drives the swing arm 308 to rotate, so that the roller 309 lifts the polyethylene tape 7 and fits it tightly on the side wall of the insulation pipe 6. At the same time, the two clamping fingers 310 open to loosen the polyethylene tape 7. Because the insulation pipe 6 rotates and moves forward under the action of the spiral conveyor line, in order to ensure that the polyethylene tape 7 fits tightly, the second telescopic cylinder 312 drives the slide plate 303 to move forward, so that the roller 309 moves forward a certain distance along with the insulation pipe 6.
