Description

Technical Field

[0001] The utility model belongs to the technical field of suede leather production, and particularly relates to a water-based coating device for suede leather. Background Technique

[0002] Suede leather, as a kind of leather with a finely flocked surface after grinding, often needs to be coated with a layer of water-based coating on its outer surface during the production process. This coating treatment not only aims to improve the hand feeling, appearance and style of suede leather, but also hopes to endow it with special functions such as heat preservation, antibacterial, sound insulation, conductivity, flash, and reflection, so as to meet the diverse market demands. However, most of the existing water-based coating devices for suede leather on the current market adopt simple roller or conveyor belt structures for guiding and coating. These devices expose two major problems in practical applications:

[0003] Firstly, the suede leather is prone to offset or wrinkle during the coating process, which not only destroys the uniformity of coating, but also seriously affects the final appearance quality of the product; secondly, after the water-based coating is applied to the suede leather, the drying process is often directly carried out, while ignoring the importance of removing the excess coating. The lack of this step not only leads to uneven distribution of the coating, but also greatly reduces the drying efficiency and increases the production energy consumption.

[0004] Therefore, it is very necessary to invent a water-based coating device for suede leather. Content of the Utility Model

[0005] The purpose of the utility model is to provide a water-based coating device for suede leather to solve the problems mentioned in the background technique.

[0006] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0007] The utility model relates to a water-based coating device for suede leather, which comprises a box body, a feed inlet, a discharge outlet, a guiding mechanism, a coating pipe, a first rotating column, a first extrusion belt, a lifting frame, a cylinder and a drying pipe. The box body is fixed to the ground by bolts. One end of the box body is provided with a feed inlet, and the other end of the box body is provided with a discharge outlet. Two guiding mechanisms are respectively fixed in the box body by bolts, and the two guiding mechanisms are respectively arranged on one side of the feed inlet and the discharge outlet. A coating pipe is fixed in the box body, the input end of the coating pipe is fixed to an external coating conveying pipeline, and a plurality of nozzles are fixed on the outer side surface of the coating pipe. Two first rotating columns are arranged on one side of the output end of the coating pipe. The two first rotating columns are rotatably installed in the box body through support bearings, and one of the first rotating columns is fixed to the output end of a first motor, and the first motor is fixed to the outer side surface of the box body by bolts. The outer side surface of the first rotating column is sleeved with a first extrusion belt, and a lifting frame is arranged on the upper side of the first extrusion belt. The upper side surface of the lifting frame is fixed to the output end of the cylinder, and the cylinder is fixed to the inner wall of the box body by bolts. A drying pipe is arranged on one side of the lifting frame, the drying pipe is fixed in the box body, and one end of the drying pipe is fixed to the output end of an external hot air blower.

[0008] Further, the guiding mechanism comprises a fixing frame, a fixed roller, a lifting roller, a limiting frame, a sliding column, a frame and a spring. The fixing frame is fixed in the box body by bolts, and the upper end of the fixing frame is rotatably installed with a fixed roller through a support bearing. A lifting roller is arranged on the upper side of the fixed roller. The lifting roller is rotatably installed in the limiting frame through a support bearing. Two sliding columns are fixedly welded to the upper side surface of the limiting frame, and the sliding columns slide through the frame. Springs are sleeved on the outer side surfaces of the sliding columns, and the springs are arranged between the limiting frame and the frame. The upper end of the frame is fixed to the inner wall of the box body by bolts. Such a setting can ensure the tension degree of the suede leather inside the box body.

[0009] Further, the lifting frame comprises a frame body, a second rotating column, a second extrusion belt, a gear set and a second motor. The frame body is fixed to the output end of the cylinder by bolts, and two second rotating columns are rotatably installed in the frame body through support bearings. The outer side surface of the second rotating column is sleeved with a second extrusion belt, and one end of one of the second rotating columns is fixed to the gear set, and the other end of the gear set is fixed to the output end of the second motor. The second motor is fixed to the outer side surface of the frame body by bolts. Such a setting can extrude the excess coating on the suede leather after the suede leather is coated, thereby improving the subsequent drying efficiency. Secondly, it can improve the bonding degree between the coating and the suede leather.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] 1. With the guiding mechanism of the present utility model, during use, the suede can pass between the fixed roller and the lifting roller under the action of an external traction device. At the same time, the lifting roller can, under the action of a spring, cause the lifting roller and the fixed roller to squeeze the suede, thereby ensuring the tension of the suede inside the box body.

[0012] 2. With the lifting frame of the present utility model, when the suede coated by the coating pipe passes between the first squeezing belt and the second squeezing belt, the cylinder can drive the lifting frame to move downward, enabling the first squeezing belt and the second squeezing belt to clamp the suede. Then, under the action of the first motor and the second motor, the first squeezing belt and the second squeezing belt move correspondingly, thereby squeezing out the excess coating on the suede and improving the bonding degree between the coating and the suede.
