Specific embodiments

[0028] Referring to Figure 1 As shown, this embodiment discloses a limiting device for processing flexible polyurethane foam rubber insulating air-conditioning ducts, including a processing table 1, a limit fixing device 3 and a rotating device 5. A controller 2 is fixedly connected to the surface of the processing table 1. The limit fixing device 3 is installed on the surface of the processing table 1 by means of the rotating device 5. The limit fixing device 3 stabilizes the position of the processed air-conditioning duct. Among them, the rotating device 5 changes the angle of the air-conditioning duct on the limit fixing device 3. An auxiliary component 4 is arranged on one side surface of the limit plate 33. When processing the air-conditioning duct, first place it on the surface of the processing table 1, and then limit and fix the air-conditioning duct through the limit fixing device 3, and operate the controller 2 on the processing table 1. When limiting and fixing the air-conditioning duct during processing operations, air-conditioning ducts of different specifications, dimensions or different shapes can be limited and fixed, which is more convenient for the operation of the staff, improves the use effect and functionality of the limiting structure, and also reduces the use cost during duct processing.

[0029] Referring to Figure 1 and Figure 2 as well as Figure 3As shown in the figure, this embodiment discloses that the limit fixing device 3 includes an assembly plate 31. The assembly plate 31 is installed on the processing table 1 by means of a rotating device 5. The peripheral surfaces of the assembly plate 31 are respectively fixedly connected with rotating shafts 32. The arc surfaces of the rotating shafts 32 are rotatably connected with limit plates 33. On the surface of the processing table 1, a servo motor 34 is fixedly connected on one side of the rotating shaft 32. The output end of the servo motor 34 is fixedly connected with a screw rod 35. The screw rod 35 is slidably connected with the inner wall of the limit plate 33. A nut 36 is threadedly connected on the arc surface of the screw rod 35. Two abutting rods 37 are fixedly connected on the arc surface of the nut 36. A limit rod 38 is fixedly connected on the arc surfaces of the two abutting rods 37. Limit grooves 39 are respectively penetrated and opened on both sides of the surface of the limit plate 33. The limit rod 38 is slidably connected with the inner wall of the limit groove 39. When using the limit fixing device 3 to limit and fix the air duct to be processed on the processing table 1, first place the air conditioner air duct on the assembly plate 31, and then start the servo motors 34 on the peripheral surfaces of the assembly plate 31 to make the screw rod 35 on the output end of the servo motor 34 rotate. Due to the sliding limit effect between the limit rod 38 on the abutting rod 37 and the limit groove 39 on the limit plate 33, the rotation of the screw rod 35 will drive the nut 36 to move upward, thereby driving the abutting rod 37 to move upward and contact and squeeze the limit plate 33, causing the limit plate 33 to rotate on the rotating shaft 32 until the limit plate 33 contacts and squeezes the surface of the air duct, so as to fix the position of the air duct. At this time, when performing limit fixing on the air conditioner air duct during processing operations, air conditioner air ducts of different specifications and sizes can be limited and fixed, which is more convenient for the operation of the staff, improves the use effect and functionality of the limit structure, and also reduces the use cost during air duct processing.

[0030] Refer to Figure 1 and Figure 2 and Figure 3 As shown in the figure, a reinforcing pad 310 is fixedly connected to one side surface of the limit plate 33. The reinforcing pad 310 is a rubber pad. Through the setting of the reinforcing pad 310, when the limit plate 33 contacts and limits the air conditioner air duct, the contact friction with the air duct can be increased, better ensuring the stability of the air duct position, and also preventing the air duct from being damaged and deformed due to excessive extrusion force.

A spring 42 is fixedly connected to one side surface of the mounting plate 41. The other end of the spring 42 is fixedly connected to the surface of the limit plate 33. Through the setting of the spring 42 and the mounting plate 41, after the air conditioner air duct is processed and the screw rod 35 rotates back, the limit plate 33 can rotate under the contraction force of the spring 42, making it more convenient to disassemble and remove the air duct.

[0031] Refer to Figure 1 and Figure 4As shown in the figure, this embodiment discloses that the rotating device 5 includes a turntable 51. The turntable 51 is rotatably connected to the surface of the processing table 1, and the turntable 51 is fixedly connected to one side surface of the assembly plate 31. One side surface of the processing table 1 is fixedly connected with a fixed plate 52. A rotating rod 53 is rotatably connected through the surface of the fixed plate 52. One end of the rotating rod 53 is fixedly connected with an adjusting disc 54. A belt 55 is provided between the adjusting disc 54 and the inner wall of the turntable 51. A plurality of uniformly circumferentially distributed fixing grooves 56 are formed on one side surface of the fixed plate 52. A bolt 57 is threadedly connected through the surface of the rotating rod 53, and the bolt 57 is inserted into the inner wall of the fixing groove 56. When the air-conditioning duct is fixed in position by the limit fixing device 3, rotate the rotating rod 53 on the fixed plate 52. The rotation of the rotating rod 53 will drive the adjusting disc 54 to rotate. At this time, the turntable 51 will rotate under the connection of the belt 55, thereby driving the position angle of the assembly plate 31 to be adjusted until the position of the air duct on the assembly plate 31 is appropriate. Rotate the bolt 57 on the rotating rod 53 until the bolt 57 is inserted into the fixing groove 56 on the surface of the fixed plate 52 to fix the position of the assembly plate 31. At this time, when processing the air-conditioning duct, the angle can be adjusted better, and the limit fixing device 3 can be better assisted to limit and fix the air-conditioning duct, thereby making it more convenient for the staff to operate and further improving the working efficiency of the air duct processing.

[0032] Referring to Figure 1 and Figure 4 As shown in the figure, this embodiment discloses that a rotating handle 58 is fixedly connected to one side surface of the rotating rod 53. A plurality of anti-slip stripes are provided on the surface of the rotating handle 58. Through the setting of the rotating handle 58, the rotation of the rotating rod 53 is made more convenient and fast, and the rotation of the assembly plate 31 on the turntable 51 can be better driven, and then the position angle of the air-conditioning duct on the assembly plate 31 can be adjusted more conveniently. A bearing 59 is fixedly connected to the arc surface of the rotating rod 53. The inner ring of the bearing 59 is fixedly connected to the rotating rod 53, and the outer ring of the bearing 59 is fixedly connected to the inner wall of the fixed plate 52. Through the setting of the bearing 59, the rotation of the rotating rod 53 on the fixed plate 52 is made more smooth and stable, reducing the rotational wear between the rotating rod 53 and the fixed plate 52, thereby ensuring the normal use of the rotating device 5.

[0033] Working principle: When using the limit fixing device 3 to limit and fix the flexible polyurethane foam rubber adiabatic air duct to be processed on the processing table 1, first place the flexible polyurethane foam rubber adiabatic air duct on the assembly plate 31, and then start the servo motors 34 on the peripheral surface of the assembly plate 31 to make the screw 35 on the output end of the servo motor 34 rotate. Due to the sliding limit effect between the limit rod 38 on the abutting rod 37 and the limit groove 39 on the limit plate 33, the rotation of the screw 35 will drive the nut 36 to move upward, thereby driving the abutting rod 37 to move upward and contact and squeeze the limit plate 33, causing the limit plate 33 to rotate on the rotating shaft 32 until the limit plate 33 contacts and squeezes the surface of the air duct, so as to fix the position of the flexible polyurethane foam rubber adiabatic air duct. At this time, when performing the limit fixing operation on the air duct, it is possible to limit and fix the flexible polyurethane foam rubber adiabatic air ducts of different specifications and sizes, which is more convenient for the operation of the staff and improves the use effect and functionality of the limit structure.

[0034] After the position of the air duct is fixed by the limit fixing device 3, turn the handle 58 on the rotating rod 53 to make the rotating rod 53 on the fixing plate 52 rotate. The rotation of the rotating rod 53 will drive the adjusting disc 54 to rotate. At this time, the turntable 51 will rotate under the connection of the belt 55, thereby driving the adjustment of the position and angle of the assembly plate 31 until the position of the air duct on the assembly plate 31 is appropriate. Turn the bolt 57 on the rotating rod 53 until the bolt 57 is inserted into the fixing groove 56 on the surface of the fixing plate 52 to fix the position of the assembly plate 31. At this time, when performing the processing operation on the air duct, it is possible to better adjust its angle, better assist the limit fixing device 3 to limit and fix the air duct, thereby making it more convenient for the operation of the staff and further improving the working efficiency of the air duct processing.
