Slide in the spout through driving piece drive sliding ring, can drive the guide plate when the sliding ring slides and rotate, and the guide plate itself has the stable effect that flow equalizes to hot-blast because parallel arrangement, and further at the pivoted in-process, can make hot-blast air current further obtain the dispersion and break up, and can not form the air current that has stronger impact and carry out rapid heating to square tube part. After adopting above-mentioned mode, hot-blast can have certain speed still, but heat distribution also can reach more even effect in the drying bath to improve the stoving effect of square tube.

Preferably, the driving piece includes along sliding ring circumference interval equidistance set up tooth piece on the sliding ring lateral wall, set up the drive gear on hot-blast import lateral wall to and be used for driving drive gear pivoted driving motor, one side that the base is close to drive gear is offered and is used for supplying drive gear to pass with the sliding ring on the matching hole of tooth piece looks meshing.

The driving motor drives the driving gear to rotate, and the driving gear drives the sliding ring to slide, so that the effect that the flow guide plate rotates to flow and disperse hot air is achieved.

Preferably, the guide plate is obliquely arranged from one side close to the hot air inlet to one side far away from the hot air inlet.

The guide plate that the slope set up can improve the guide effect to hot-blast.

Preferably, a plurality of flow guide holes are uniformly formed in the flow guide plate.

The guide holes can lead one part of hot air to be guided by the guide plate when the hot air passes through the guide plate, and the other part of hot air is dispersed through the guide holes, thereby achieving better shunting effect.

Preferably, the side wall of the drying pool is provided with a wind shield, the wind shield is opposite to the hot air inlet, and a gap for flowing hot air exists between the wind shield and the hot air inlet.

The wind shield blocks the air flow coming out of the hot air inlet and guides the air flow to the four sides of the guide plate, so that the phenomenon that the hot air flow is too large and some impurities in the hot air directly collide the side wall of the square tube to influence the quality of the square tube is avoided.

Preferably, the wind deflector is arranged in an arc shape protruding to one side far away from the hot air inlet.

The curved wind deflector can better guide hot air to both sides.

Preferably, the center of one side of the wind shield close to the hot air inlet is fixedly connected with a hemispherical guide block.

The hemispherical guide blocks may allow the hot air to be better dispersed to be guided to both sides of the wind guard.

Preferably, a row of air guide holes are formed in the two sides of the wind deflector along the length direction of the wind deflector.

The air guide holes can enable hot air guided to two sides of the wind shield to flow out of the wind shield more smoothly, and therefore the speed of heat dispersion is accelerated.

In summary, the present application has the following beneficial effects:

1. through setting up can pivoted guide plate and further set up a plurality of water conservancy diversion holes on the guide plate to improve hot-blast dispersed effect, improve hot-blast homogeneous stability after getting into the stoving pond from hot-blast import.

2. Through setting up the deep bead to and set up modes such as globular guide piece on the deep bead, with improve hot-blast dispersion effect, and avoid hot-blast direct impact to square tube surface, and cause the square tube uneven of being heated.
