The first pressing plate 15 is fixedly connected to the first cutting gun 18, and the second pressing plate 16 is fixedly connected to the connecting frame 9. The second cutting gun 22 is slidably provided on one side of the connecting frame 9. The first cutting gun 18 and the second cutting gun 22 are used to cut the first bottle body 11.

A collecting box 4 is provided on one side of the two conveying plates 1.

[0023] Specifically, when producing liquefied gas cylinders, it is necessary to process the bottle top, bottle body and bottle bottom separately, and then weld the bottle top, bottle body and bottle bottom together, and then transport the welded liquefied gas cylinder to a subsequent processing area. When making the bottle top, the steel plate must be stamped into shape by a stamping device, and the stamped bottle top is transported to a cutting area, and the bottle top is trimmed and laser cut for subsequent welding processing. Since the bottle top needs to be connected to the air inlet valve and some other pressure devices, a connection port must be cut out on the bottle top by laser cutting. After cutting the bottle top, the bottle top must be transported to subsequent cutting, and the debris on the cutting table and the waste cut must be cleaned. The above production steps are relatively complicated, and the bottle top needs to be transported to a cutting table for trimming and cutting, and then transported to another cutting table to cut the air inlet valve port of the bottle top, and then the cut bottle top is transported out of the cutting table, and then the debris and waste on the cutting table are cleaned and recycled, which reduces the production efficiency of the liquefied gas cylinder, and the energy consumption and time required for producing the liquefied gas cylinder are relatively high; In this example, the first bottle body 11 is the bottle top. The first bottle body 11 is placed on the conveyor belt 2. The hydraulic cylinder 3 is started to move the transmission platform 12 downward and the first transmission rod 34 is pressed downward against the conveyor belt 2. The driving roller 5 is started to rotate the conveyor belt 2 to transfer the first bottle body 11 to the transmission roller 13 between the transmission platforms 12. The transmission of the conveyor belt 2 will drive the first transmission rod 34 to rotate, and the transmission rollers 13 on both sides are rotated through the first transmission rod 34. Then, the chain 36 is used to rotate multiple transmission rollers 13 together so that the first bottle body 11 can be moved smoothly. The first bottle body 11 is moved to the transmission roller 13, the rotation of the driving roller 5 is stopped, the first pressing plate 15 and the second pressing plate 16 are rotated to press the first bottle body 11 onto the transmission roller 13, and the driving wheel 38 is fitted with the first bottle body 11 by sliding the fixing box 45. At this time, the driving roller 5 is started again to rotate the driving wheel 38 through the transmission device, and the first bottle body 11 can be rotated through the driving wheel 38. The first cutting gun 18 is started to perform laser cutting and trimming on the bottom of the first bottle body 11, and the second cutting gun 22 is started to laser cut the top of the first bottle body 11 to trim the first bottle body 11. 1 is opened, the first cutting gun 18 and the second cutting gun 22 are both laser cutting cutting heads, and one end of the first cutting gun 18 and the second cutting gun 22 are connected to the laser cutting machine. When the first bottle body 11 is cut, the first pressing plate 15 and the second pressing plate 16 are rotated to no longer block and press the first bottle body 11. At this time, the first bottle body 11 is moved out of the transmission platform 12 by the rotation of the transmission roller 13 and transferred to the other side of the conveyor belt 2 for subsequent transfer processing. The debris and waste generated after cutting the first bottle body 11 are transferred to the conveyor belt 2 by the conveyor belt 2. The first bottle body 11 can be recycled in the collection box 4 on one side; that is, after the first bottle body 11 is transported by the conveyor belt 2, the first bottle body 11 can be rotated by the driving wheel 38 to perform laser cutting on the first bottle body 11. The debris and waste after the first bottle body 11 is cut can be transported to one side through the conveyor belt 2 and the drive roller 13, which can simplify the cutting process of the liquefied gas cylinder. After the first bottle body 11 is transported to the processing area, it can be directly processed without transportation, and the debris and waste generated after cutting can be directly recycled, which speeds up the working efficiency of laser cutting of liquefied gas cylinders.

[0025] Specifically, when the first transmission rod 34 presses the conveyor belt 2, the conveyor belt 2 will be supported by the support roller 14 so that the conveyor belt 2 can always remain in a plane, so that the conveyor belt 2 can better convey the first bottle body 11 for processing.

[0026] like Figures 1 to 9As shown, fixed rods 6 are fixedly connected on both sides of the two conveying plates 1, and two driving rollers 5 are slidably connected to the two fixed rods 6 on both sides. First springs 7 are sleeved on one side of the multiple fixed rods 6, and one end of the multiple first springs 7 is fixedly connected to the driving roller 5, and the other end of the multiple first springs 7 is fixedly connected to the conveying plate 1.

The driving wheel 38 can be driven to rotate by the transmission of the conveyor belt 2.

[0030] like Figures 1 to 9 As shown, a fourth spring 39 is sleeved on one side of the sliding rod 40, one end of the fourth spring 39 is fixedly connected to the fixed cylinder 37, and the other end of the fourth spring 39 is fixedly connected to the sliding rod 40. A limit stop is provided between the sliding rod 40 and the fixed cylinder 37, so that the sliding rod 40 can rotate with the fixed cylinder 37 and slide in the fixed cylinder 37.

[0031] Specifically, when the driving wheel 38 is in close contact with the first bottle body 11 and drives the first bottle body 11 to rotate, the first bottle body 11 pushes the driving wheel 38 to move with the fixing box 45, and the fixing box 45 moves with the sliding rod 40 to make the sliding rod 40 slide in the fixing cylinder 37, and compress the fourth spring 39 to make the driving wheel 38 close to the surface of the first bottle body 11, so that the sliding rod 40 can slide in the fixing cylinder 37 and can also rotate with the fixing cylinder 37.

[0032] like Figures 1 to 9As shown, two telescopic rods 31 are fixedly connected to one side of the first pressing plate 15, and one end of the two telescopic rods 31 is rotatably connected to a roller 33.

[0033] Specifically, when the first pressing plate 15 rotates to press and fix the first bottle body 11, the first bottle body 11 presses the roller 33 to make the roller 33 slide in the first pressing plate 15, and compresses the third spring 32 through the telescopic rod 31 to make the roller 33 close to the first bottle body 11. When the driving wheel 38 drives the first bottle body 11 to rotate, the first bottle body 11 will rotate through the roller 33. The driving wheel 38 and the roller 33 cooperate to make the first bottle body 11 rotate, reducing scratches and damage to the side wall of the first bottle body 11.

[0034] like Figures 1 to 9 As shown, a cylinder 17 is fixedly connected to one side of the first pressing plate 15 , a pressing block 41 is fixedly connected to the output end of the cylinder 17 , and a fixing column 42 is fixedly connected to one side of the pressing block 41 on one side of the first pressing plate 15 .

[0035] Specifically, after the first cutting gun 18 cuts and trims the first bottle body 11, the cylinder 17 is started to move the pressing block 41 downward. The pressing block 41 is an arc-shaped inclined block. The excess waste can be pressed onto the fixed column 42 through the pressing block 41 and wrapped around the fixed column 42. The waste generated after cutting the first bottle body 11 can be preliminarily collected, which is convenient for subsequent recycling and utilization of the waste. Embodiment 2

[0038] like Figures 1 to 9 As shown, one side of the sliding cylinder 21 is slidably connected to a sliding frame 25, and one side of the sliding frame 25 is rotatably connected to two grinding rollers 29. A torsion spring 30 is sleeved between the two grinding rollers 29, and both ends of the torsion spring 30 are fixedly connected to the two grinding rollers 29 respectively.

[0039] Specifically, after the top of the first bottle body 11 is cut, the rotating box 19 is rotated by the connecting frame 9 to move the sliding frame 25 to the cutting position of the first bottle body 11, and the first bottle body 11 is rotated to grind the cutting position of the first bottle body 11 by the grinding roller 29 so as to subsequently weld the top of the first bottle body 11 and the intake valve. The two grinding rollers 29 are pressed against the cutting position of the first bottle body 11 and the torsion spring 30 is used to make the two grinding rollers 29 close to the first bottle body 11 for grinding.
