Abstract

The utility model discloses a drying device. Relates to surface drying equipment, in particular to plastic film drying equipment. Provides a drying device which can quickly dry a plastic film and can not form bubbles on the surface of the film. The plastic film winding device comprises an oven, wherein the oven is communicated with an air supply device, a feed port and a discharge port are arranged on the side wall of the oven, and a plastic film is wound from the discharge port after entering from the feed port. A supporting plate is arranged in the oven, and the plastic film is wound on the supporting plate. The hot air flow blows the plastic film and then directly returns to the air supply device through the air return opening on the same side for circular heating, and cannot blow to the lower part of the plastic film, so that the plastic film cannot form bubbles due to the blowing of the hot air flow (no matter the plastic film faces one side of the air supply opening or one side back to the air supply opening), the dried plastic film has good quality, and the defective rate is low.

SUMMERY OF THE UTILITY MODEL

In order to overcome the defects of the prior art, the utility model provides a drying device which can blow dry plastic film quickly and can not form bubbles on the surface of the film.

The utility model discloses a following technical scheme realizes: the drying device comprises an oven, wherein the oven is communicated with an air supply device, a feed port and a discharge port are formed in the side wall of the oven, and a plastic film is wound from the discharge port after entering from the feed port. A supporting plate is arranged in the oven, and the plastic film is wound on the supporting plate.

The oven is characterized in that a plurality of parallel conveying rollers are arranged on the supporting plate, an air supply outlet and an air return inlet of the air supply device are respectively arranged on the side wall of the oven, the air supply outlet is arranged below the supporting plate, and the air return inlet is arranged above the supporting plate.

The supporting plate is provided with a plurality of ventilation grooves, the ventilation grooves and the conveying rollers are arranged at intervals, and hot air blown out from the air supply outlet is blown to the plastic film through the ventilation grooves.

And a material receiving box is arranged at the bottom of the oven and is arranged right below the supporting plate.

The supporting plate comprises a first supporting plate and a second supporting plate which are symmetrically arranged, one end of the first supporting plate and one end of the second supporting plate are fixed to the top of the oven, and the first supporting plate and the second supporting plate are fixed to the central axis of the top of the oven.

The other ends of the first supporting plate and the second supporting plate are respectively fixed on the side wall of the oven and fixed on the lower edge of the air supply outlet.

Compared with the prior art, the utility model discloses plastic film is from the feed inlet feeding, cover in the backup pad, the supply-air outlet blows in hot-blastly, directly blow on plastic film, owing to there is the supporting role of backup pad, bubbling phenomenon can not appear in plastic film, the top of supply-air outlet is located to the return air inlet, that is to say, establish the homonymy at plastic film, air supply arrangement inner loop heating is got back to directly through the return air inlet of homonymy behind the plastic film to the hot air weathers, can not blow plastic film's below, therefore, plastic film can not form the tympanic bulla (no matter be towards one side of supply-air outlet or one side of supply-air outlet dorsad all can not form the tympanic bulla) because of the reason that the hot air flow.

in the figure: 1. an air supply outlet; 2. an air return opening; 3. a support plate; 4. a conveying roller; 5. a material receiving box; 6. an oven; 7. an air supply device.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that the embodiments or technical features described below can be arbitrarily combined to form a new embodiment without conflict.

As shown in fig. 1-2, the drying device comprises an oven 6, wherein the oven 6 is communicated with an air supply device 7, a feed port and a discharge port are arranged on the side wall of the oven 6, and a plastic film is wound from the discharge port after entering from the feed port. A supporting plate 3 is arranged in the oven 6, and the plastic film is wound on the supporting plate 3. Hot air of the air supply device 7 enters from the air supply opening 1 and is directly blown onto the plastic film, and is not blown into the plastic film from the lower part of the plastic film, and the position of the air return opening 2 is higher than that of the air supply opening 1, so that bubbling can not be formed on the surface of the plastic film, the dried plastic film has good quality, and the defective rate is low.

The oven is characterized in that a plurality of parallel conveying rollers 4 are arranged on the supporting plate 3, an air supply opening 1 and an air return opening 2 of the air supply device 7 are respectively arranged on the side wall of the oven 6, the air supply opening 1 is arranged below the supporting plate 3, and the air return opening 2 is arranged above the supporting plate 3. Firstly, a plastic film is fed from a feeding hole and covers a support plate 3, hot air is blown into an air supply opening 1 and is directly blown onto the plastic film, the plastic film cannot bubble due to the supporting effect of the support plate 3, an air return opening 2 is arranged above the air supply opening 1, namely, the plastic film is arranged on the same side of the plastic film, the hot air directly returns to an air supply device 7 through the air return opening 2 on the same side after the plastic film is dried by the hot air, the plastic film is circularly heated and cannot be blown to the lower side of the plastic film, therefore, the plastic film cannot bubble due to the blowing of the hot air (no matter the plastic film faces one side of the air supply opening 1 or faces away from one side of the air supply opening 1, the dried plastic film is good in quality, and.
