[0046] The flexible strip 107 has a sliding groove 1071, and a sealing strip 108 is slidably disposed in the sliding groove 1071. A fixing sleeve 109 is installed on the sealing strip 108, and a sealing sheet 110 is disposed in the fixing sleeve 109. A winding assembly 12 is disposed on the sealing frame 105. A clamping mechanism 2 and a plasma cutting mechanism 3 are disposed on one side of the fixing seat 100, and the sealing strip 108 is located in the clearance groove 1052.

[0047] like Figures 3-14 As shown, the winding assembly 12 includes: winding rods 121, two winding rods 121 rotatably mounted on the sealing frame 105; ring clamps 122, ring clamps 122 mounted on the winding rods 121; first baffles 123, two first baffles 123 arranged opposite to each other; rotating rods 124, four rotating rods 124 rotatably mounted between the two first baffles 123, and first slots 1241 are formed in the two rotating rods 124; third gears 125, third gears 125 mounted on the rotating rods 124, and four third gears 125 meshing; and switching assembly 13, switching assembly 13 mounted on the sealing frame 105.

[0048] like Figures 3-14As shown, the switching assembly 13 includes: a first linear drive 131, which is mounted on the sealing frame 105 and whose output end is connected to a first baffle 123; two second baffles 132, which are arranged opposite to each other and connected to the first baffle 123; two rotating shafts 133, which are rotatably disposed between the two second baffles 132 and have a second slot 1331 inside; a transmission wheel 134, which is mounted on the rotating shafts 133; a belt 135, which is sleeved on the outside of the two transmission wheels 134; and a second rotary drive 136, which is mounted on the sealing frame 105 and drives one of the winding rods 121 to rotate.

[0049] like Figures 3-14 As shown, the drive assembly 11 includes: two rotating rods 111 rotatably mounted on the sealing frame 105; two first gears 112 mounted on the rotating rods 111, and a plurality of third slots 1072 provided on the outer side of the flexible strip 107, with the first gears 112 meshing with the third slots 1072; two rotating shafts 113 rotatably mounted on the top of the sealing frame 105; two second gears 114 mounted on the top of the rotating rods 111 and the top of the rotating shafts 113, with the four second gears 114 meshing; and a first rotation drive 115 mounted on the sealing frame 105, which drives one of the rotating rods 111 to rotate.

[0050] like Figure 1 and Figure 2 As shown, the clamping mechanism 2 includes a support seat 201 located on the ground. The support seat 201 is attracted by negative pressure and can rotate.

[0051] In this embodiment, the tubular tank is placed on the support seat 201. The support seat 201 adsorbs the tubular tank through negative pressure. The lifting frame 104 slides on the second guide rail 103, driving the flexible strip 107 and the sealing strip 108 to move to the outside of the tubular tank.

[0052] The first rotary drive 115 drives one of the rotating rods 111 to rotate, causing the first gears 112 on the two rotating rods 111 to rotate in opposite directions. Since the first gear 112 meshes with the third slot 1072, the two ends of the drive flexible strip 107 slide inward along the slide groove 1051, and the drive flexible strip 107 tightens and adheres to the outside of the tubular tank.

[0053] While the flexible strip 107 is tightened, the second rotary drive 136 drives the winding rod 121 to synchronously wind up the sealing strip 108.

[0054] In this embodiment, in the initial state, the ring clip 122 is inserted into the first slot 1241, and the second rotary drive 136 drives one of the winding rods 121 to rotate, thereby driving the other winding rod 121 to rotate. The two winding rods 121 rotate in opposite directions, so as to realize the function of the second rotary drive 136 driving the winding rods 121 to synchronously wind up the sealing tape 108.

[0055] The first linear drive 131 drives the first baffle 123 to move downward, causing the second baffle 132 to move synchronously, so that the ring 122 is inserted into the second slot 1331. At this time, the second rotary drive 136 drives one of the winding rods 121 to rotate, causing the other winding rod 121 to rotate, and the two winding rods 121 rotate in the same direction (one winding, the other unwinding). At this time, the sealing tape 108 is driven to slide in the sliding groove 1071, so that the fixing sleeve 109 is aligned with the plasma cutting mechanism 3.

[0056] like Figure 1 , Figure 2 , Figures 10-18 As shown, the plasma cutting mechanism 3 includes a fixed rod 301 on the ground, a top plate 302 is installed on the top of the fixed rod 301, a second linear drive 303 is installed on the top plate 302, and a clamping cylinder 304 is installed at the output end of the second linear drive 303.

[0057] A rotating disk 305 is rotatably mounted on the fixed rod 301. The rotating disk 305 has three sets of receiving cavities 3051. One set of receiving cavities 3051 contains a plasma cutting nozzle 306; another set of receiving cavities 3051 contains a friction rod 307; and the remaining set of receiving cavities 3051 contains a coating rod 308. The plasma cutting nozzle 306, friction rod 307, and coating rod 308 are equipped with connecting components 31. It should be noted that a sponge is provided in front of the coating rod 308, and a pipe (not shown in the figure) is provided on the coating rod 308. One end of the pipe is connected to the sponge, and the other end is connected to the reinforcing agent supply device. The reinforcing agent enhances the plasma cutting effect.

[0058] The connecting assembly 31 includes: a mounting sleeve 311, which is respectively mounted on the plasma cutting nozzle 306, the friction rod 307, and the coating rod 308; a fixing sleeve 109 having multiple positioning holes 1091; a mounting sleeve 311 having multiple mounting grooves 3111; an elastic connector 312, which is disposed in the mounting grooves 3111; and a positioning ball 313, which is disposed at the free end of the elastic connector 312. It should be noted that the positioning ball 313 is inserted into the positioning hole 1091 under the elastic force of the elastic connector 312, which can fix the mounting sleeve 311 in the fixing sleeve 109.

[0059] In this embodiment, the clamping cylinder 304 clamps the friction rod 307, and the second linear drive 303 drives the friction rod 307 to move forward and insert into the fixed sleeve 109. The friction rod 307 is connected to the fixed sleeve 109 through the connecting component 31. At this time, the front end of the friction rod 307 abuts against the outside of the tubular tank.

[0060] The second rotary drive 136 drives one of the winding rods 121 to rotate, which in turn drives the other winding rod 121 to rotate. The two winding rods 121 rotate in the same direction, driving the sealing strip 108 to slide in the sliding groove 1071, driving the friction rod 307 to rub the cut area on the outside of the tubular tank, and then transporting the friction rod 307 into the receiving cavity 3051.

[0061] In this embodiment, the drive rotating disk 305 rotates, so that the applicator 308 is aligned with the fixed sleeve 109, the clamping cylinder 304 clamps the applicator 308, and the second linear drive 303 drives the applicator 308 to move forward and insert into the fixed sleeve 109. The applicator 308 is connected to the fixed sleeve 109 through the connecting component 31. At this time, the sponge at the front end of the applicator 308 is in contact with the outside of the tubular can.

[0062] The drive sealing strip 108 slides in the sliding groove 1071, and the sponge at the front end of the drive applicator 308 applies the reinforcing agent to the cut area on the outside of the rubbed tubular can, and then the applicator 308 is transported into the receiving cavity 3051.

[0063] In this embodiment, the drive rotary disk 305 rotates so that the plasma cutting nozzle 306 is aligned with the fixed sleeve 109, the clamping cylinder 304 clamps the plasma cutting nozzle 306, and the second linear drive 303 drives the plasma cutting nozzle 306 to move forward and insert into the fixed sleeve 109. The plasma cutting nozzle 306 is connected to the fixed sleeve 109 through the connecting component 31.

[0064] The drive sealing strip 108 slides within the sliding groove 1071, driving the plasma cutting nozzle 306 to perform annular cutting on the tubular tank. The sealing strip 108 plays a sealing role (a sealed space is formed between the sealing strip 108, the flexible strip 107, and the tubular tank), and the smoke and debris generated during cutting will not directly diffuse into the air, which is beneficial to environmental cleanliness.

[0065] One of the mounting sleeves 311 is equipped with a pipe 314, which is connected to an inert gas source. The fixed sleeve 109 is equipped with a one-way valve. The inert gas is discharged into the sealed space through the pipe 314, and the cutting is performed under the inert gas.

[0066] It should be noted that this embodiment can not only cut circular tubular cans, but also perform placement and tightening processes, friction processes, coating processes, and plasma cutting processes on square tubular cans. In order to facilitate the placement of circular and square tubular cans, circular and square grooves can be provided on the support 201 at the same time, and the rotation of the support 201 is driven by a motor.

[0067] In order to complete the annular cut of the circular tubular tank, the bearing seat 201 rotates, causing the circular tubular tank to rotate at a certain angle, and cuts the area pressed by the sealing gasket 106. In order to complete the cut of the square tubular tank, the moving frame 102 slides on the first guide rail 101 and cuts the area pressed by the sealing gasket 106.

[0068] Example 2: This example provides a cutting method for a plasma cutting device used in chemical tank production, including the following steps:

[0069] Step 1, Placement and Tightening Process: Place the tubular tank on the support seat 201. The support seat 201 adsorbs the tubular tank through negative pressure. The lifting frame 104 slides on the second guide rail 103, driving the flexible strip 107 and the sealing strip 108 to move to the outside of the tubular tank.

[0070] The first rotary drive 115 drives one of the rotating rods 111 to rotate, causing the first gears 112 on the two rotating rods 111 to rotate in opposite directions. Since the first gear 112 meshes with the third slot 1072, the two ends of the drive flexible strip 107 slide inward along the slide groove 1051, and the drive flexible strip 107 tightens and adheres to the outside of the tubular tank.

[0071] While the flexible strip 107 is tightened, the second rotary drive 136 drives the winding rod 121 to synchronously wind up the sealing strip 108.

[0072] Step 2, Switching Process: In the initial state, the ring 122 is inserted into the first slot 1241. The second rotary drive 136 drives one of the winding rods 121 to rotate, which in turn drives the other winding rod 121 to rotate. The two winding rods 121 rotate in opposite directions, so as to realize the function of the second rotary drive 136 driving the winding rods 121 to synchronously wind up the sealing tape 108.

[0073] The first linear drive 131 drives the first baffle 123 to move downward, causing the second baffle 132 to move synchronously, so that the ring 122 is inserted into the second slot 1331. At this time, the second rotary drive 136 drives one of the winding rods 121 to rotate, causing the other winding rod 121 to rotate, and the two winding rods 121 rotate in the same direction (one winding and one unwinding). At this time, the sealing tape 108 is driven to slide in the sliding groove 1071, so that the fixing sleeve 109 is aligned with the plasma cutting mechanism 3.

[0074] Step 3, Friction Process: Clamping cylinder 304 clamps friction rod 307, and second linear drive component 303 drives friction rod 307 to move forward and insert into fixed sleeve 109. Friction rod 307 is connected to fixed sleeve 109 through connecting component 31. At this time, the front end of friction rod 307 abuts against the outside of tubular tank.

[0075] The second rotary drive 136 drives one of the winding rods 121 to rotate, which in turn drives the other winding rod 121 to rotate. The two winding rods 121 rotate in the same direction, driving the sealing strip 108 to slide in the sliding groove 1071 and driving the friction rod 307 to rub the cut area on the outside of the tubular tank.

[0076] Step 4, application process: drive the rotary disk 305 to rotate, so that the application rod 308 is aligned with the fixed sleeve 109, the clamping cylinder 304 clamps the application rod 308, and the second linear drive 303 drives the application rod 308 to move forward and insert into the fixed sleeve 109.
