For explaining the technical solution of the present invention, the following detailed description is made with reference to the specific drawings and examples:
referring to fig. 1 and 2, an embodiment of the present invention provides a tuyere mechanism, which is mainly used in an oven for spraying hot air to a substrate conveyed in the oven to dry the substrate after coating a film. The substrate may be paper, film, aluminum foil, pole piece 200, etc., and the pole piece 200 is used as an example for the following description, and other types of substrates can be explained similarly.
The tuyere mechanism includes a tuyere 1 and a spacer 2.
Air nozzle 1 locates one side of pole piece 200, and air outlet 101 has been seted up to one side of air nozzle 1, and the air-out direction of air outlet 101 is towards pole piece 200 to make hot-blast from air outlet 101 blowout and blow to pole piece 200 along the air-out direction of air outlet 101, in order to realize the stoving effect to pole piece 200. The partition 2 is rotatably arranged on the tuyere 1, and the rotating plane of the partition 2 is parallel to the conveying direction of the pole piece 200. The surface of the partition 2 is a smooth curved surface, and at least a part of the partition 2 extends out of the air nozzle 1 along the air outlet direction of the air outlet 101, that is, at least a part of the partition 2 is located between the pole piece 200 and the air nozzle 1, so as to separate the pole piece 200 from the air nozzle 1.
It should be noted here that, when the pole piece 200 performs the drying operation, the pole piece 200 is conveyed by an external conveying device, and a conveying direction of the pole piece 200 is a length direction of the pole piece 200, specifically, a horizontal direction x shown in fig. 2, that is, the conveying direction may be one of two directions in the horizontal direction x. During operation, the wound pole piece 200 is unwound and then continuously conveyed along the length direction thereof at one side of the air nozzle 1, so that the hot air ejected from the air outlet 101 can continuously dry each part of the pole piece 200 along the length direction. Pole piece 200 is after being dried gradually, easy emergence is curled, the phenomenon of crumpling, pole piece 200 is before the output oven this moment, when pole piece 200 scrapes off isolator 2 under the effect of wind pressure and self gravity, isolator 2 contacts pole piece 200 and produces reverse frictional force, thereby make isolator 2 produce the trend of the opposite direction rotation along the direction of delivery of pole piece 200, so, the frictional force that isolator 2 produced has the trend of the opposite direction delivery of the direction of delivery of pole piece 200, thereby realize the reverse tensile effect to pole piece 200. For example: when the conveying direction of pole piece 200 is horizontal direction x in fig. 2 to the right, and pole piece 200 touches spacer 2, spacer 2 and pole piece 200 generate friction force and have a tendency to convey pole piece 200 to the left, that is, spacer 2 has a tendency to rotate counterclockwise, thereby realizing the effect of stretching pole piece 200 in the reverse direction. In addition, in this embodiment, when pole piece 200 scrapes off spacer 2 and contacts spacer 2, and pole piece 200 is still transported, one side of pole piece 200 slides over the outer surface of spacer 2, and because the outer surface of spacer 2 is a smooth curved surface, the flatness of pole piece 200 can be improved.
Here, the air outlet direction of the outlet 101 is a tendency of the hot air to be substantially ejected from the outlet 101, that is, a direction of the outlet 101 toward the pole piece 200. In the actual drying operation, in order to improve the drying effect of pole piece 200, air nozzles 1 are disposed on both the upper side and the lower side of pole piece 200, so that air nozzle 1 in this embodiment can be disposed on the upper side or the lower side of pole piece 200, that is, can be disposed as an upper air nozzle or a lower air nozzle. As shown in fig. 2, the air nozzle 1 is disposed at the lower side of the pole piece 200, and is a lower air nozzle, so that the air outlet direction of the air outlet 101 is substantially upward, that is, the air outlet 101 is disposed upward; accordingly, the general extension of the partition 2 is upward, as shown in the vertical direction y in fig. 2, at least a part of the partition 2 extends out of the tuyere 1 along the air outlet direction of the air outlet 101, which means that at least a part of the partition 2 extends out of the tuyere 1 upward, that is, at least a part of the partition 2 is located between the pole piece 200 and the tuyere 1, in other words, in the vertical direction y, the top of the partition 2 is higher than the air outlet 101 of the tuyere 1, and when the partition 2 is a cylindrical member, a partial cylindrical surface obtained by cutting the partition 2 parallel to the plane of the pole piece 200 is higher than the air outlet 101, so as to separate the pole piece 200 and the tuyere 1. Wherein the direction y is perpendicular to the direction x. When the air nozzle 1 is located on the upper side of the pole piece 200, that is, the air nozzle 1 is an upper air nozzle, the air outlet direction of the air outlet 101 is substantially downward, that is, the air outlet 101 is disposed downward, and accordingly, the substantially extending trend of the partition 2 is downward, and at least a part of the partition 2 extends downward out of the air nozzle 1, so that at least a part of the partition 2 is located between the pole piece 200 and the air nozzle 1. It should be noted that, hereinafter, the air nozzle 1 is located at the lower side of the pole piece 200 as an example, and the air nozzle 1 located at the upper side of the pole piece 200 can be explained in the same way, and is not described in detail below.
In addition, in order to improve the air outlet efficiency of the air outlet 101, the air outlet 101 is opened on one side of the air nozzle 1 facing the pole piece 200, that is, the air outlet 101 is opened on the upper side of the air nozzle 1.
The embodiment of the utility model provides an in, through adopting above-mentioned technical scheme for hot-blast air outlet 101 that can pass through tuyere 1 blows to the substrate, with the stoving substrate. And, the spacer 2 stretches out outside tuyere 1 along the air-out direction of air outlet 101, in order to realize the isolation of tuyere 1 and substrate, when the substrate is suspended and is scraped and bump the tuyere mechanism under the action of hot-blast gravity and self, the substrate can only touch spacer 2, avoid tuyere 1 to scrape and bump the substrate and damage the substrate, and spacer 2 sets up to its surface be smooth curved surface, then can not be damaged by spacer 2 when the substrate touches spacer 2, thereby reduced the damage of tuyere 1 to the substrate, the outward appearance and the quality of substrate have been guaranteed. In addition, when the base material touches the partition 2 in the conveying process, because the rotating plane of the partition 2 is parallel to the conveying direction of the base material, a friction force is generated when the partition 2 is in contact with the base material, the friction force enables the partition 2 to generate a trend of rotating in the direction opposite to the conveying direction of the base material, so that a reverse stretching effect on the base material is generated, the base material passes through and contacts the outer surface of the partition 2 in the conveying process, the flatness of the base material is improved, the base material is prevented from being curled and wrinkled, and the quality of the base material is improved.
