[0002] Leather products are widely used in many fields such as clothing, footwear, furniture, etc. With the continuous improvement of the market's requirements for the quality and appearance of leather products, leather processing technologies are also constantly developing and improving. In the leather processing process, sizing is a key link, which can improve the performance of leather such as hand feeling, glossiness, and durability; Traditional spraying machines usually adopt fixed nozzles, and the spraying angle and flow rate of the sizing agent are relatively fixed, making it difficult to meet the sizing requirements of different parts of the leather, easily resulting in inconsistent sizing thickness on the leather surface, and it is easy to miss spraying at the edges of the leather, affecting the product quality. During the spraying process, the sizing agent is likely to drip from the edges of the leather, causing waste of materials, polluting the working environment, and increasing the cleaning cost and production cost; Traditional leather spraying and conveying mechanisms cannot well adapt to the shape of the leather, and are prone to cause displacement or deformation of the leather during the conveying process, and it is easy to miss spraying at the edges of the leather, affecting the accuracy and uniformity of spraying.

The flow of the slurry on the spiral blade drives the connecting rod and the liquid distribution block and the liquid distribution disk at its bottom to rotate, improving the dispersion degree of the slurry.

[0010] Preferably, the conveying mechanism includes a first motor and a transmission shaft. The first motor is fixedly installed on the side of the frame through a bracket.

[0011] Preferably, the conveying roller includes an elliptical roller body. The diameter of the elliptical roller body gradually decreases from the middle to both ends. Card wire grooves are formed on the outer surface of the elliptical roller body. The conveying line is arranged inside the card wire grooves. The elliptical roller body makes the conveying line have a higher middle and lower ends when conveying the leather, effectively solving the problem that the edges of the leather are easily missed by spraying.

The liquid guiding groove guides the slurry flowing down from both sides of the leather to the liquid inlet, and finally is collected by the liquid receiving box.

[0013] The present invention provides a leather spraying machine with uniform sizing. It has the following beneficial effects: 1. The leather spraying machine with uniform sizing, through the setting of the conveying mechanism, the first motor drives the transmission shaft to rotate, and then the elliptical roller fixed on the outer surface of the transmission shaft rotates. The elliptical roller drives the conveyor belt to convey the leather through the card wire groove. Since the diameter of the elliptical roller gradually decreases from the middle to both ends, when transporting, the leather presents a state of being higher in the middle and lower on both sides on the surface of the conveyor belt. During spraying, due to the action of gravity, the sizing liquid will flow to both sides of the leather, effectively solving the problem that the edges of the leather are easily missed during spraying.

[0014] 2. The leather spraying machine with uniform sizing, through the setting of the liquid storage component, the liquid pump is started, and the sizing liquid in the liquid storage barrel is pumped out through the liquid outlet pipe. After being pressurized by the liquid pump, it is transported to the fixed cover through the liquid guide pipe for storage and waiting to enter the spraying component. The liquid storage barrel stores a large amount of sizing liquid, and the liquid pump provides pumping power to ensure the continuous and stable transportation of the sizing liquid. The fixed cover collects and temporarily stores the sizing liquid to continuously supply the spraying component. The liquid storage component ensures the continuity and stability of the sizing liquid supply during the spraying process, avoiding spraying interruption or unevenness caused by feeding problems, and improving production efficiency and product quality.

[0015] 3. The leather spraying machine with uniform sizing, through the setting of the spraying component, the second motor runs to drive the rotating rod to rotate. The rotating rod drives the rotating disk to rotate through the annular frame, and the rotating disk drives the nozzle component at the bottom to rotate accordingly. The sizing liquid in the liquid storage component enters the nozzle component through the liquid inlet pipe. The spiral guide piece in the liquid inlet pipe makes the sizing liquid flow spirally. Inside the nozzle component, the push piece applies pressure, and the spiral blade, liquid distribution block and liquid distribution disk work together to make the sizing liquid disperse and spray evenly. The spraying component realizes an all-round and uniform spraying effect, meets the sizing requirements of different parts of the leather, greatly improves the leather sizing quality, and reduces the defective rate.

[0016] 4. The leather spraying machine with uniform sizing, through the setting of the liquid receiving mechanism, during the spraying process, the sizing liquid flowing down from both sides of the leather drips onto the liquid receiving mechanism, and along the liquid guide groove, it flows into the liquid receiving box through the liquid inlet. The liquid receiving mechanism timely collects the excess sizing liquid flowing down from both sides of the leather during the spraying process, realizes the recycling of the sizing liquid, saves production costs, and at the same time keeps the environment around the equipment clean and reduces the pollution to the working site.

[0017] 5. The leather spraying machine with uniform sizing, through the setting of the nozzle component, the sizing liquid enters the pressure pipe inside the nozzle housing. Under the action of pressure, it pushes the push piece. The push piece slides through the spring in the pressure pipe to pressurize the sizing liquid. At the same time, the sizing liquid flows through the spiral blade to make the connecting rod rotate. The rotating ring frame rotates at the bottom of the pressure pipe, drives the connecting rod to drive the liquid distribution block to rotate, and makes the sizing liquid disperse evenly. The nozzle component ensures that the pressure of the sprayed sizing liquid is stable and the distribution is uniform, making the leather sizing thickness consistent and improving the product quality.
