Detailed Description

The technical solution of the present invention will be further explained with reference to the accompanying drawings and embodiments.

As shown in fig. 1, the embodiment of the present invention provides a drying device for covering film, comprising a drying box 1, and a material placing mechanism (not shown) and a drawing mechanism (not shown) disposed at two sides of the drying box 1, wherein two end faces of the drying box 1 are provided with a material inlet and a material outlet, a plurality of tension rollers 2 for tensioning the covering film are disposed in the drying box 1, a bottom plate of the drying box 1 is slidably connected with a hot air box 3, the hot air box 3 is disposed in the drying box 1, a plurality of hot air nozzles 4 communicated with the interior of the hot air box 3 are uniformly disposed on the outer surface of the hot air box 3, the bottom of the hot air box 3 is connected with a fan 5 disposed outside the drying box 1 through a hose, an air inlet of the fan 5 is connected with an air heating box 6, a heat source is disposed in the air heating box 6, a driving mechanism for driving the hot air box 3 to reciprocate is disposed in the, and a through hole for the hose to move is formed in the bottom plate of the drying box 1.

In the present embodiment, the heat source is an electric heater, and the air heating box 6 is used to heat air. After the air is heated to a proper temperature, the air is conveyed to the hot air box 3 by the fan 5, and the hot air box 3 reciprocates under the action of the driving mechanism to spray hot air to the covering film in the drying box 1. Because the hot air nozzle 4 is in continuous motion, the sprayed hot air forms air flow, which is beneficial to drying the covering film. The feed inlet and the discharge outlet are not required to be opened too big, the cover film is just required to pass through, the length of the through hole is not required to be too long, and the drying box 1 is preferably arranged at 1/10 of the length so as to reduce the overflow of heat and tail gas. The movement of the hot gas box 3 is mainly to form a gas flow, so that the hot gas is uniformly distributed, and the movement amplitude is not too large.

Be provided with two baffles 9 in the stoving case 1, two baffle 9 install respectively in the both ends of stoving case 1, and the side of baffle 9 is fixed in on the lateral wall of stoving case 1, be provided with the exhaust hole on the roof of stoving case 1, the exhaust hole is located between the terminal surface of baffle 9 and stoving case 1, exhaust hole intercommunication blast pipe 10, blast pipe 10 intercommunication air extractor 11, air extractor 11 passes through pipeline intercommunication tail gas treatment pond 12.

The tail gas treatment tank 12 is provided with a corresponding treatment solution according to the specific components of the tail gas. The baffle 9 is arranged so that the air extractor 11 preferentially extracts air between the baffle 9 and the end surface of the drying box 1 without interfering with normal drying operation.

Actuating mechanism is the cylinder, or actuating mechanism includes sector gear 8, sliding frame 7 and motor, the motor is installed in stoving case 1 outside, and its pivot stretches into stoving case 1 inside and connects sector gear 8, the level is provided with slide rail 13 on the 1 lateral wall of stoving case, sliding frame 7 is rectangle frame structure, sliding frame 7's frame with slide rail 13 sliding connection, sliding frame 7's frame with 3 fixed connection of hot-air box, all set up the rack on sliding frame 7's the inside casing, the rack with sector gear 8 meshes. The stroke of the hot air box 3 is shorter, the frequency is faster, and the motor and the sector gear 8 are more suitable.

The distance between two baffles 9 is greater than the movement stroke of drying box 1 (so can make hot gas shower nozzle 4 be between two baffles 9 all the time to avoid hot gas just being taken away by blowout promptly, extravagant heat energy), and two baffles 9 all incline to set up and make the distance between two baffles 9 grow gradually from the top down.

The plurality of tensioning rollers 2 are arranged in a broken line mode. When tensioning roller 2 is the broken line setting, can prolong its length in stoving case 1, improve drying efficiency, make the space utilization in stoving case 1 more reasonable.
