[0003] In the Chinese utility model patent with publication number CN221288443U, a leather spraying device is disclosed, which starts the operation of the motor, rotates the motor and drives the stirring blade to rotate synchronously. The rotation of the stirring blade can stir the paint in the paint box, thereby preventing the paint from drying out due to standing for too long.

[0042] The working principle of this utility model is as follows:
[0043] During use, the leather to be sprayed is firstly controlled to be transported in the chassis 1 by the existing traction and winding mechanism, and the feeding guide rollers 2 provided on the left and right outer walls of the chassis 1 are used to improve the smoothness and stability of the leather transmission process.

At this time, the multiple first nozzles 73 and the multiple second nozzles 82 can start spraying the leather. Moreover, the hollow tube 71 is in an inverted "concave" shape, and the multiple first nozzles 73 are equidistantly installed on the inner sides of the upper and lower ends. Therefore, during the leather transmission process, the leather can be sprayed on both sides, and the spraying speed is faster and the efficiency is higher.
[0044] During the spraying process, the servo motor 9 can be started, and the two fixing blocks 72 can be controlled to drive the two hollow tubes 71 to move simultaneously along the guide rod 11 in the direction of approaching each other through the rotation of the bidirectional screw rod 10. Figure 5 Under the action of the multiple groups of connecting rods 83 shown in FIG, the diverter pipe 81 can be pushed to the right, so that the spraying width of the machine can be adaptively adjusted according to the actual width of the leather, thereby avoiding pigment waste and achieving the purpose of saving resources;
[0045] When the leather after spraying enters the drying chamber, the hot air pump 5 can be turned on to transport the hot air into the drying chamber. The setting of the two partitions 3 can slow down the escape speed of the hot air, making it convenient to heat and dry the leather after spraying. At the same time, the cold air pump 6 can be turned on to cool the leather entering the cooling chamber, avoiding softening of the leather due to heating and drying, and preventing adhesion between leathers, which affects subsequent processing.
[0046] The above are only preferred specific embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Any equivalent changes, modifications, substitutions and variations made by technicians in this technical field based on the concept of the present invention through logical analysis, reasoning or limited experiments on the basis of existing technologies should be within the scope of protection determined by the claims.
