[0002] Leather is a denatured and non-perishable animal skin obtained through physical and chemical processes such as dehairing and tanning. It is made of natural protein fibers tightly woven in three-dimensional space, forming a special grain on its surface, showing a natural texture and luster, while having a comfortable feel.

[0003] Leather slurrying is an indispensable step in the leather production process. When slurrying, it is necessary to ensure that the slurry is applied evenly and the quality of the slurry is guaranteed. In the current leather slurrying device, the spacing between the slurry rollers is mostly fixed when in use, and the distance cannot be adjusted according to the thickness of the leather, which cannot meet the production needs. Moreover, the slurry is easy to solidify during the slurrying process, which affects the leather slurrying effect and is not practical enough. Utility Model Content

The two groups of lifting sliders 6 are slidably mounted on the fixed frame 2 through cooperation with the limiting grooves, and the lower brush roller 7 is rotatably mounted on the two groups of lifting sliders 6. A slurry box 22 is fixedly connected to the bottom of the two groups of lifting sliders 6. Part of the lower brush roller 7 is in the slurry box 22 and is fixed. A slurry box 8 is fixedly installed on the top of the frame 2, and a box cover 9 is installed on the top of the slurry box 8 through a hinge cover. Two sets of lock buckles 10 are installed at the front end of the box cover 9 and the front end of the slurry box 8. The bottom of the slurry box 8 is connected with an arc-shaped material port, and an arc-shaped slurry coating rubber plate 11 that cooperates with the upper slurry brush roller 3 is fixedly connected to the arc-shaped material port. A plurality of groups of slurry discharge holes are equidistantly provided on the arc-shaped slurry coating rubber plate 11. A stirring rod 12 is rotatably installed on the slurry box 8. A plurality of groups of stirring blades 13 are equidistantly provided in a circular array on the outer wall of the stirring rod 12. A large pulley 14 is provided on the fixed sleeve at the right end of the upper slurry brush roller 3, and a small pulley 15 is provided on the fixed sleeve at the right end of the stirring rod 12. A transmission belt 16 is provided on the transmission sleeves of the large pulley 14 and the small pulley 15;When in use, the slurry box 8 and the slurry box 22 are filled with an appropriate amount of slurry, and the arc-shaped slurry coating rubber plate 11 is kept in contact with the outer wall of the upper brush roller 3. The upper brush roller 3 blocks the slurry outlet when it is not rotating, which can prevent the slurry from flowing out. When it is necessary to brush the leather, the servo hydraulic cylinder 5 is started to push the lifting slider 6 upward, and then the lifting slider 6 drives the lower brush roller 7 to move upward, so that the lower brush roller 7 contacts the upper brush roller 3, and then the upper brush roller 3 is rotated by the handwheel 4 to rotate the upper brush roller 3. During the rotation of the upper brush roller 3, the slurry is gradually and evenly applied to the surface of the upper brush roller 3. The upper brush roller 3 drives the lower brush roller 7 to rotate through friction, so that the slurry in the slurry box 22 is evenly applied to the surface of the lower brush roller 7, and then the brushing is started. According to the thickness of the leather, the servo hydraulic cylinder 5 is started to drive the servo hydraulic cylinder 5 through the lifting slider 6 The lower slurry brush roller 7 and the slurry box 22 move downward, and the distance between the upper slurry brush roller 3 and the lower slurry brush roller 7 is adjusted. Then, the leather passes between the upper slurry brush roller 3 and the lower slurry brush roller 7. Under the action of external traction, the leather drives the upper slurry brush roller 3 and the lower slurry brush roller 7 to rotate through friction, so that the slurry on the upper slurry brush roller 3 and the lower slurry brush roller 7 is evenly applied to both sides of the leather. Since the lower slurry brush roller 7 continuously rotates in the slurry box 22, the slurry in the slurry box 22 will not solidify. When the upper slurry brush roller 3 rotates, it drives the stirring rod 12 to rotate through the transmission belt 16, so that the stirring rod 12 drives the stirring blade 13 to stir the slurry in the slurry box 8. The stirring of the stirring blade 13 prevents the slurry in the slurry box 8 from solidifying. Therefore, the distance between the slurry brush rollers can be adjusted according to the thickness of the leather to meet production needs, effectively prevent the solidification of the slurry, avoid affecting the slurry brushing effect of the leather, and improve practicality.

[0021] A collecting trough 17 is placed on the bottom plate 1, and a U-shaped baffle 18 is fixedly connected to the rear end of the fixing frame 2, and the rear side of the collecting trough 17 rests on the U-shaped baffle 18; by setting the collecting trough 17, the fallen slurry can be collected during the slurry brushing process to avoid waste, and the collecting trough 17 can be limited by the U-shaped baffle 18 to ensure that the collecting trough 17 is directly below the lower slurry brushing roller 7 when placed.

[0022] The front end of the slurry box 8 is provided with an observation mirror 19; by providing the observation mirror 19, it is convenient to observe the remaining slurry in the slurry box 8 so as to add slurry in time.

[0023] A crank 20 is provided on the outer side of the hand wheel 4 for rotation; by providing the crank 20 , it is possible to make rotation of the hand wheel 4 more convenient.

[0024] A handle 21 is fixedly provided at the front end of the collecting tank 17 ; the provision of the handle 21 makes it more convenient to take the collecting tank 17 out.

[0025] When the upper brush roller 3 is in the state of being brushed, the upper brush roller 3 is in the state of being brushed, and the lower brush roller 3 is in the state of being brushed. The slider 6 drives the lower brush roller 7 and the slurry box 22 to move downward, adjusts the distance between the upper brush roller 3 and the lower brush roller 7, and then passes the leather with a clean surface between the upper brush roller 3 and the lower brush roller 7. Under the action of external traction, the leather drives the upper brush roller 3 and the lower brush roller 7 to rotate through friction, so that the slurry on the upper brush roller 3 and the lower brush roller 7 is evenly smeared on both sides of the leather. Since the lower brush roller 7 rotates continuously in the slurry box 22, the slurry in the slurry box 22 will not solidify. When the upper brush roller 3 rotates, the stirring rod 12 is driven by the transmission belt 16 to rotate, so that the stirring rod 12 drives the stirring blade 13 to stir the slurry in the slurry box 8, and the large pulley 14 is larger than the small pulley 15, which can make the upper brush roller 3 drive the stirring rod 12 to rotate more easily. The stirring of the stirring blade 13 prevents the slurry in the slurry box 8 from solidifying, and the fallen slurry is collected through the collecting trough 17 to avoid waste.
