Description

Technical Field

[0001] The utility model relates to the technical field of leather processing equipment, in particular to an anti-jamming leather roll coating equipment. Background Art

[0002] In daily life, leather, wood boards, cardboard, iron plates, etc. usually need to be coated with a layer of coating according to requirements. The coating can be an anti-corrosion coating, a waterproof coating, a repair coating, etc. For example, for leather, there are defects such as scars and concave lines on the surface of natural leather. At this time, it is necessary to size the scar and concave line parts on the leather surface to make the color of the leather surface meet the consistency requirements. At present, the slurry is usually coated on the leather surface by spraying or roll coating. However, since leather is a natural product, problems such as scars, naturally formed concave lines and uneven thickness on its surface cause the coating to only be distributed on the surface, and the coating cannot fill the scar and concave line parts, so the quality and grade of the product are greatly reduced. At present, to solve this problem, all rely on manual brushing the disabled (scars and concave lines) positions of the leather evenly and then performing subsequent processing, with low processing efficiency and unstable quality.

[0003] In view of the above problems, a patent with the patent number 202111546605.7 has been invented, which discloses a paint brushing device, including a frame, a conveying mechanism, a brushing roller, a brushing roller driving assembly and a feeding mechanism; the conveying mechanism is installed on the frame, and both ends of the brushing roller are rotatably connected to the frame and driven to rotate by the brushing roller driving assembly; the brushing roller is located above the conveying mechanism and a brushing gap is formed therebetween; the feeding mechanism includes at least one material box; the material box is installed on the frame, a paint cavity is provided in the material box, a slender discharge groove communicating with the paint cavity is opened at the bottom of the material box, the slender discharge groove is covered with a discharge member, and a plurality of discharge holes are evenly provided at the discharge member at the slender discharge groove; the paint in the paint cavity flows out from the plurality of discharge holes through the slender discharge groove and is evenly added to the surface of the brushing roller or the surface of the product, so that the paint is evenly distributed on the surface of the brushing roller or the surface of the product, the paint feeding uniformity is good, the paint uniformity is high, and the quality of the product is good. However, the paint brushing device still has the following problems: 1. The centers of the brushing roller and the conveying roller of the existing paint brushing device are on the same axis. During use, when the brushing roller and the conveying roller rotate in the same direction, the leather is pushed outward by the conveying roller when entering, resulting in the phenomenon that the leather is bounced back when entering, causing the leather to be stuck and damaged, and resulting in difficult leather feeding; and when discharging after processing, due to the relatively tight contact between the conveying roller and the discharging belt, the discharging is stuck, affecting the discharging efficiency and the overall leather processing efficiency; 2. The cleaning effect of the existing paint brushing device is poor, resulting in residues, affecting the processing quality and efficiency of the next material; 3. The discharging method of the existing paint brushing device mostly uses a conveyor belt to discharge the product. The conveyor belt is fixedly arranged at the discharging end of the paint brushing device. Due to the lack of an adjustment structure, it is easy to cause an increase in the floor area and needs to be customized according to the placement space, increasing the customization cost.
