[0003] Suspension coating machine oven supports the pole piece by the wind force of the air nozzle, including the main body of the oven, the upper and lower air inlet chambers and the upper and lower air nozzles. The upper and lower air nozzles are respectively installed on the upper and lower air inlet chambers. The position of the air nozzle, the size and uniformity of the air outlet will affect the stability of the suspension of the pole piece, the drying effect, and then affect the performance of the lithium battery
However, the air nozzles in the prior art cannot control the uniformity of the air outlet

Embodiment Construction
[0020] Hereinafter, several different preferred embodiments of the present invention will be described with reference to the accompanying drawings, in which the same reference numerals in different figures represent the same components.
[0021] The present invention aims to provide a suspension coating machine oven 1 and its tuyere 14, the tuyere 14 has a uniform wind speed, stable suspension of pole pieces, and good drying effect.
[0022] Such as figure 1 The suspension coating machine oven 1 includes an oven main body 11, an upper air inlet chamber 12 provided on the top wall of the oven main body 11, a lower air inlet chamber 13 provided on the bottom wall of the oven main body 11 and a nozzle 14. There are several air nozzles 14 which are divided into an upper air nozzle 141 and a lower air nozzle 142. The upper air nozzle 141 is provided on the bottom wall of the upper air inlet chamber 12, and the lower air nozzle 142 is provided on the top wall of the lower air inlet chambe...

The invention provides an air nozzle of a suspension type coating machine drying box. The air nozzle of the suspension type coating machine drying box comprises an inner cover, an outer cover and a buffering plate; an air inlet is formed in the outer cover; the outer cover is of an opening structure; a gap between the outer cover and the inner cover forms an air outlet; and the buffering plate is arranged between the air inlet and the air outlet. According to the air nozzle, because the buffering plate located between the air inlet and the air outlet is arranged, the air outflow speed of the air outlet is uniform, suspension of pole pieces is stable, and the drying effect is good. The invention further provides the suspension type coating machine drying box with the air nozzle.
Description
Technical field [0001] The invention relates to a coating machine, in particular to an oven of a suspension coating machine and a tuyere structure of the oven. Background technique [0002] In the coating process, the drying speed directly determines the coating speed; the drying quality directly determines the performance of the lithium battery, so an efficient and high-quality drying technology is very important, for lithium battery slurry , After coating, the thickness of the pole piece is thick, the coating amount is large, and the drying load is large. The suspension drying technology is used for drying treatment, which can improve the drying efficiency. [0003] The drying oven of the suspension coating machine is supported by the wind of the air nozzle, including the main body of the oven, the upper and lower air inlet chambers, and the upper and lower air nozzles. The upper and lower air nozzles are respectively installed on the upper and lower air inlet chambers. The posi...
