[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figure 1-5 This utility model provides a technical solution: an environmentally friendly waste gas collection pipe for treating volatile organic compounds in printing, including a support frame 1. A motor is installed inside the support frame 1, and one end of the motor's output shaft is connected to a drive wheel via a coupling. A driven wheel is correspondingly provided on one side of the drive wheel, and a conveyor belt 2 is fitted onto the outer wall of both the drive wheel and the driven wheel. A fixed frame 3 is provided on one side of the support frame 1, and an operating frame 4 is provided on the fixed frame 3. A first electric push rod 5 is installed inside the operating frame 4, and a first telescopic arm 6 is provided below the first electric push rod 5. A printing head 7 is provided at the lower end of the first telescopic arm 6. A second electric push rod 8 is provided on one side of an electric push rod 5 within the operating frame 4, and a second telescopic arm 9 is provided below the second electric push rod 8. A protective cover 10 is provided at the lower end of the second telescopic arm 9, and a telescopic rod 12 is provided on the upper surface of the other end of the protective cover 10. The telescopic rod 12 is inserted into a hollow rod 11, and the upper end of the hollow rod 11 is connected to the operating frame 4. It should be noted that the motor and multiple sets of electric push rod assemblies in this device are connected to the power supply equipment through power cords, and their working status is monitored in real time by a controller, thereby ensuring that the printing head 7 can perform printing work normally.
[0021] Furthermore, under the action of the first electric push rod 5, the printing head 7 forms a vertical lifting structure with the fixed frame 3 through the first telescopic arm 6, and the protective cover 10 also forms a vertical lifting structure with the fixed frame 3 through the second telescopic arm 9, hollow rod 11, and telescopic rod 12 under the action of the second electric push rod 8. Thus, under the action of the first electric push rod 5, the printing head 7 can be lifted and lowered normally, and under the action of the second electric push rod 8, the printing head 7 can be protected during the working process so that the exhaust gas generated during the printing process can be collected through the exhaust pipe 13.
[0022] The protective cover 10 has an exhaust pipe 13 on one side, and a waste gas collection pipe 14 is spirally attached to the exhaust pipe 13. A connecting pipe 15 is provided between the waste gas collection pipes 14, and the other end of the waste gas collection pipe 14 is connected to an exhaust fan.
[0023] Furthermore, the inner wall of the connecting pipe 15 and the outer wall of the exhaust gas collection pipe 14 are provided with matching threads, and the connecting pipe 15 and the exhaust gas collection pipe 14 form a spiral locking structure. Thus, the exhaust gas collection pipe 14 assembly can be easily disassembled through multiple sets of connecting pipes 15 so as to clean the inside of the exhaust gas collection pipe 14 regularly.
[0024] The exhaust gas collection pipe 14 has a thread on its inner wall at one end near the exhaust pipe 13, and a fixing ring 16 is provided inside the exhaust gas collection pipe 14, with a filter screen 17 on the fixing ring 16.
[0025] Furthermore, the outer wall of the fixing ring 16 is provided with threads that fit into the inner wall of the exhaust gas collection pipe 14, and the filter screen 17 forms a spiral locking structure with the exhaust gas collection pipe 14 through the fixing ring 16, thereby preventing external impurities from entering the exhaust gas collection pipe 14 through the filter screen 17, and the filter screen 17 can be replaced periodically through the fixing ring 16.
[0026] The exhaust gas collection pipe 14 has multiple sets of connecting blocks on its inner wall, and the other end of the connecting block is connected to the inner pipe. An insulation plate 18 is inserted between the exhaust gas collection pipe 14 and the inner pipe. Multiple sets of bolt holes are opened on the exhaust gas collection pipe 14, and bolts 19 are spirally screwed into the spiral holes. The other end of the bolts 19 is spirally screwed onto the insulation plate 18.
[0027] Furthermore, the insulation board 18 is connected to the exhaust gas collection pipe 14 by multiple sets of bolts 19 to form a spiral locking structure. This allows the insulation board 19 to be spirally installed by the bolts 18 when the outside temperature is low, thereby avoiding the impact of low temperature on the exhaust gas collection pipe 14.
[0028] Working Principle: When using the environmentally friendly printing volatile organic compound (VOC) waste gas collection pipe, during the operation of the printing head 7, the protective cover 10 is lowered synchronously by the second electric push rod 8 and hollow rod 11 assembly. This protects the printing head 7 during printing without affecting its raising and lowering, allowing the waste gas generated during dyeing to be collected promptly through the protective cover 10 and exhaust pipe 13. Simultaneously, the filter screen 17 prevents external impurities from entering the waste gas collection pipe 14 and affecting it. The filter screen 17 can be periodically disassembled and replaced using the fixing ring 16 to ensure its ventilation. The waste gas collection pipe 14 is used continuously... During use, the multiple sets of exhaust gas collection pipes 14 can be disassembled periodically via a spiral to clean the inside of the exhaust gas collection pipes 14 regularly, thereby preventing the accumulation of impurities inside the pipes from affecting their working effect. If the outside temperature is low, the exhaust gas collection pipes 14 can be disassembled via multiple sets of connecting pipes 15 to insert the insulation board 18 through both ends of the exhaust gas collection pipes 14. At the same time, the insulation board 18 can be spirally installed via multiple sets of bolts 19 to prevent the low temperature from affecting the exhaust gas collection pipes 14 themselves, further ensuring the collection effect of the exhaust gas collection pipes 14 on the exhaust gas generated during the printing process. This is the usage process of the environmentally friendly exhaust gas collection pipe for treating volatile organic compounds in printing.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
