The countercurrent suspension type oven comprises a left half oven 1 and a right half oven 2 which are oppositely folded into a whole during working, and a printing film 20 passes through a gap between the left half oven and the right half oven.
The structure of the left half oven 1 sequentially comprises a first main air inlet pipe 3 and a first main air exhaust pipe 4 which are transversely arranged from outside to inside, a first middle air inlet pipe 7 and first air exhaust pipes 11 at two sides of the first middle air inlet pipe which are longitudinally arranged in the first main air inlet pipe, and a blowing pipe 91, an air shovel 93, an air deflector 94 and a waste gas guide pipe 95 which are transversely arranged in the first middle air inlet pipe and are connected with each other. Two ends of the waste gas guide pipe are respectively inserted with the first exhaust pipes 11 at two sides. The top air inlet 92 of the blowing pipe 91 is connected with the air outlet 97 of the first intermediate air inlet pipe 7. The connection relationship between the left half oven parts is as follows: the transverse main air inlet pipe 3 is communicated with a first middle air inlet pipe 7 through a first communication port 12, and the first middle air inlet pipe 7 is provided with 6 air inlets which are respectively butted with the air inlets 92 of 6 air blowing pipes. The blowing pipe 91 is connected with a waste gas guide pipe 95 through an air shovel 93 and an air deflector 94, and two ends of the waste gas guide pipe 95 are spliced with the first exhaust pipes 11 on two sides in a hole percent mode. The first main exhaust duct 4 is connected with the first exhaust ducts 11 on two sides through the second connecting opening 13. The flow direction of the drying air is: the dry air enters the first middle air inlet pipe 7 from the first main air inlet pipe 3 and is distributed to enter the six air blowing pipes 91, the dry air is blown to the waste gas guide pipe 95 through the air deflector 94 by the air shovel 93 under the wind pressure of the fan, a drying chamber is formed between the air deflector between the air shovel and the waste gas guide pipe and the printing film, the dry air passing through the drying chamber is divided to two ends by the waste gas guide pipe 95 and respectively enters the first exhaust pipes 11 at two sides to be discharged. The drying air is blown by the air shovel 93 to the waste gas guide pipe through the air deflector 94, and the direction of the drying air is opposite to the moving direction of the printing film, so that a large reverse speed difference is generated, a large friction force is generated, and a good drying effect is achieved on the printing film.
The right half oven 2 sequentially comprises a second main air inlet pipe 5 and a second main air exhaust pipe 6 which are transversely arranged from outside to inside, a second middle air inlet pipe 8 and two side second air exhaust pipes 14 which are longitudinally arranged in the second main air exhaust pipe, a suspended air pipe 101, a top suspended support plate 103 and a nozzle 104 which are transversely arranged in the second main air exhaust pipe and are connected with each other, an air inlet 102 is arranged at the bottom of the suspended air pipe, arc-shaped air deflectors 105 are arranged at two sides of the suspended air pipe, a groove 108 capable of containing a printing film carrier roller 107 is formed between the two arc-shaped air deflectors, two transverse ends 109 of the groove are exhaust gas exhaust channels, and exhaust gas is exhausted into the two side second air exhaust pipes 14 from the. The connection relationship among all the components of the right half oven is as follows: the transverse second main air inlet pipe 5 is communicated with a second middle air inlet pipe 8 through a third communication port 15, the second middle air inlet pipe 8 is not provided with a top cover, but is provided with a covering plate, namely a suspension bottom plate, and is provided with 6 air inlets which are respectively butted with the air inlets 102 of the 6 suspension air pipes. The top of the suspension air pipe is provided with a suspension supporting plate 103, two sides of the suspension air pipe are provided with arc-shaped air deflectors 105 to form a groove 108 for placing a printing film carrier roller, and the carrier roller groove is a channel for connecting two second exhaust pipes 14 at two sides to exhaust waste gas. The second main exhaust duct 6 is connected to the second exhaust ducts 14 on both sides through a fourth communication port 16. The flow direction of the drying air is: the dried air enters a second middle air inlet pipe 8 from a second main air inlet pipe 5 through a third communication port 15, is distributed to enter six suspension air pipes 101 through 6 air inlets arranged on a suspension bottom plate on the second middle air inlet pipe, the dried air entering the suspension air pipes is blown out from air nozzles 104 of a top suspension support plate under the air pressure of a fan, so that the printed film is in a suspension state, meanwhile, the reverse side of the printed film is dried, and the blown dried air enters second exhaust pipes 14 at two sides through carrier roller grooves between two adjacent suspension air pipes and is exhausted. It can be seen from above that, the printing film will receive the same wind pressure on the positive and negative sides under the effect of the suspension tuber pipe of the half oven in the right side, the suspension layer board and the wind shovel of the half oven in the left side, aviation baffle, consequently make the printing film be the suspension state at the motion process, can not produce the shake, so guaranteed printing machine chromatography precision. The drying air blown out by the suspension supporting plate air nozzle not only ensures that the printing film does not shake, but also blows and dries the reverse side of the printing film, and the drying efficiency of the printing film is further improved.
The air shovel and the air deflector of the left half oven of the invention generate movement in the opposite direction of the printed film and larger speed difference, thereby playing the main drying role. The suspension air pipe, the suspension supporting plate and the printing film of the right half oven are blown in the vertical direction to suspend the printing film, so that mutually vertical movement and speed difference are generated, and the second-position drying effect is achieved. Therefore, the oven is called a day-counterflow, suspension oven.
According to the invention, the first exhaust pipes 11 at two sides of the left half oven are of an open top-cover-free structure, the second exhaust pipes 14 at two sides of the right half oven are of an open top-cover-free structure, and when the left half oven and the right half oven are folded into a whole, the openings of the two exhaust pipes are folded into a whole correspondingly, so that a complete exhaust pipe at each of two sides of the suspension oven is formed.
The invention is mainly used for: 1. gravure press drying (electronic shaft press, mechanical shaft press); 2. coating machines (lithium batteries, adhesive tapes, adhesive film machines and other electronic product coating machines); 3. a dry compound machine.
The oven can be used vertically (left and right half ovens) or horizontally (upper and lower half ovens).
In fig. 12, 14 and 15, the reference number 18 is a carrier roller pressing plate, and the section view of the exhaust duct at the two sides of the right half oven is A-A.
The drying air mentioned in the text is sent into an air inlet pipeline of the drying oven through a drying fan after the air is heated.
