[0023] A printing lamination with a waste gas recovery structure comprises a casing 1, a door 2 is symmetrically and hingedly provided on the front of the casing 1, a first handle is symmetrically and fixedly provided on the door 2, a filter box 3 is fixedly connected to the center of the top of the casing 1, a door 4 is symmetrically and hingedly provided on the front of the filter box 3, a second handle is symmetrically and fixedly provided on the door 4, an exhaust fan 5 is fixedly connected to the top of the filter box 3 and the exhaust fan 5 is connected to the inner cavity of the filter box 3, air collecting components are symmetrically provided on both sides of the filter box 3, and a filter component is provided in the inner cavity of the filter box 3.

[0024] The gas collecting component includes a gas collecting hopper 6 arranged at the top of the inner cavity of the casing 1, and the top of the gas collecting hopper 6 is connected to a gas collecting hose 7. The top of the gas collecting hose 7 passes through the top wall of the casing 1, and an air guide pipe 8 is arranged above the gas collecting hose 7. One end of the air guide pipe 8 passes through the top wall of the casing 1 and is connected to the gas collecting hose 7, and the other end of the air guide pipe 8 passes through the bottom of the side wall of the filter box 3 and is connected to the inner cavity of the filter box 3. The tops of the two side walls of the casing 1 are symmetrical and fixedly connected with installation boxes 9. An electric push rod 10 is fixedly connected to the side wall of the inner cavity of the installation box 9. The electric push rod 10 passes through the side wall of the casing 1 and extends to the inner cavity of the casing 1, and the output end of the electric push rod 10 is fixedly connected to the gas collecting hopper 6. The gas collecting component can collect the waste gas generated by the printed matter during the coating heating process, and its waste gas recovery structure is relatively flexible, so the waste gas recovery The range is relatively wide, so that the waste gas can be recovered more comprehensively and the waste gas recovery is more thorough; the filter component includes a metal rubber filter 11 arranged at the bottom of the inner cavity of the filter box 3, an activated carbon filter 12 is arranged above the metal rubber filter 11, and a ULPA ultra-high efficiency filter 13 is arranged above the activated carbon filter 12.

[0025] Working process: when the waste gas is recovered, the exhaust fan 5 is started, and the exhaust fan 5 will change the pressure difference in the casing 1. Under the action of the internal and external pressure difference, the waste gas generated by the coating heating is sucked into the gas collecting hose 7 through the gas collecting bucket 6, and finally introduced into the filter box 3 after passing through the air guide pipe 8, so as to recover the waste gas. At the same time of waste gas recovery, the electric push rod 10 is started to make the electric push rod 10 reciprocate regularly. The extension and contraction of the electric push rod 10 will continuously drive the gas collecting bucket 6 to move through its output end, thereby changing the gas collecting position of the gas collecting bucket 6. Therefore, the range of waste gas recovery is relatively wide, so that the waste gas can be recovered more comprehensively and the waste gas recovery is more thorough. The waste gas entering the filter box 3 will pass through the metal rubber filter 11, the activated carbon filter 12 and the ULPA ultra-high efficiency filter 13 in turn.

The ULPA ultra-high efficiency filter 13 has a filtration efficiency of more than 99.9999% for particles larger than 0.3 microns. Its filter material has a compact structure, high filtration efficiency, large filtration area and strong dust holding capacity. The exhaust gas that has been filtered and purified multiple times is finally discharged by the exhaust fan 5, thereby avoiding affecting the processing personnel and the surrounding environment when it is discharged.
