The first end and the second end of the steam-water separator 23 are connected to the passage of the first pipe assembly 20, and the drain pipe 26 is connected to the third end of the steam-water separator 23.

[0035] Specifically, a heating source inputs steam through the inlet of pipe 10, and the steam outputs from the outlet of pipe 10 to the first pipe assembly 20 and the second pipe assembly 30. A steam-water separator 23 is installed on either the first pipe assembly 20 or the second pipe assembly 30. When the steam-water separator 23 is installed on the first pipe assembly 20, the steam from the first pipe assembly 20 enters the first end of the steam-water separator 23, which processes the steam and separates the water from the gas. The hot gas generated by the steam-water separator 23 enters the first pipe assembly 20 from its second end, causing the first pipe assembly 20 to output hot gas. The water output from the third end of the steam-water separator 23 is discharged through the drain pipe 26. Meanwhile, the second pipe assembly 30 outputs steam, thus achieving the use of the same heating source to output different types of heat sources, allowing the steam and hot gas to heat different types of cardboard. The steam-water separator 23 discharges the water separated from the steam through the drain pipe 26.

[0036] Preferably, the steam-water separator 23 can be a steam-water separator according to Chinese patent number CN201010548949.7, which can achieve the effect of steam-water separation.

[0037] Preferably, the first piping assembly 20 includes a first pipe 21 and a first control valve 22, and the second piping assembly 30 includes a second pipe 31 and a second control valve 32. The first end of the first pipe 21 is connected to the output end of the inlet pipe 10, and the second end of the first pipe 21 has a first outlet 25. The first control valve 22 and the steam-water separator 23 are both installed on the first pipe 21, with the first control valve 22 positioned between the output end and the steam-water separator 23. The first end of the second pipe 31 is connected to the output end of the inlet pipe 10, and the second end of the second pipe 31 has a second outlet 33.

[0038] Preferably, the first pipeline assembly 20 further includes a pneumatic regulator 24, which is installed on the first pipeline 21 and positioned between the first outlet 25 and the steam-water separator 23. Specifically, this pneumatic regulator 24 is used to regulate the flow rate within the first pipeline 21, so that the amount of hot air at the first outlet 25 can be adjusted by the pneumatic regulator 24.

[0039] Preferably, the dual-path control mechanism 100 further includes a control cabinet 50, and a support 40 has a first side 410 and a second side 420. A first pipeline assembly 20 is installed on the first side 410, and both the second pipeline assembly 30 and the control cabinet 50 are installed on the second side 420, with the second pipeline assembly 30 and the control cabinet 50 arranged vertically.

Specifically, since the first pipeline assembly 20 has a steam-water separator 23 and a pneumatic regulator 24, and the steam-water separator 23 and the pneumatic regulator 24 are heavy, the second pipeline assembly 30 and the control cabinet 50 are both installed on the second side 420, and the second pipeline assembly 30 and the control cabinet 50 are arranged vertically. This ensures that the first side 410 and the second side wall 420 of the support 40 are subjected to balanced forces, preventing tipping due to the greater weight on one side of the support 40 and improving the stability of the support 40. Furthermore, the drain pipe 26 is located on one side of the control cabinet 50 to prevent the control cabinet 50 from interfering with the connection of the drain pipe 26 to the output pipe, thereby improving the convenience of connecting the drain pipe 26 to the output pipe.

[0040] Preferably, the control cabinet 50 has a control circuit, which is electrically connected to the steam-water separator 23 and the pneumatic regulator 24 respectively; the control cabinet 50 has solenoid valves, which are electrically connected to the first control valve 22 and the second control valve 32 respectively.

A first control valve 22 is installed on the second pipe body 212, and a second control valve 32 is installed on the fifth pipe body 312. The second pipe body 212 and the fifth pipe body 312 are staggered.

[0042] Specifically, flange connections are used between the first pipe body 211 and the second pipe body 212, between the second pipe body 212 and the third pipe body 213, between the fourth pipe body 311 and the fifth pipe body 312, and between the fifth pipe body 312 and the sixth pipe body 313. Two adjacent flanges are fastened with bolts, and a sealing gasket is placed between the two flanges to achieve a good sealing effect and prevent fluid or gas leakage at the connection. Since the first control valve 22 is installed on the second pipe body 212 and the second control valve 32 is installed on the fifth pipe body 312, and the second and fifth pipe bodies 212 are staggered, the first control valve 22 and the second control valve 32 are also staggered. This avoids interference between the first control valve 22 and the second control valve 32 during installation and operation, improving convenience.

[0043] Furthermore, the first control valve 22 and the second control valve 32 can be angle seat valves. The solenoid valve is electrically connected to the angle seat valve. Generally, the pneumatic angle seat valve is used as the main valve, while the solenoid valve is used as an auxiliary valve. The control of the pneumatic angle seat valve is coordinated by a switching power supply. In industrial processes, this combination valve is commonly used for flow regulation, pressure control, and level control. Both the pneumatic angle seat valve and the solenoid valve have the characteristics of fast response, accuracy, and stability, thus becoming an important component of industrial automation control.

[0044] Preferably, the bracket 40 has a through-hole 404, and the drain port 27 of the drain pipe 26 is positioned facing the through-hole 404. Specifically, this through-hole 404 can be used to place the output pipe, allowing the output pipe to pass through from one side of the bracket 40 and connect with the drain port 27 of the drain pipe 26; when it is necessary to move the dual-path control mechanism 100, the output pipe can also be coiled up and placed at the through-hole 404 of the bracket 40.

[0045] Preferably, the dual-path control mechanism 100 further includes a filter 102 and a tee connector 101.
