Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of PU synthetic leather production, in particular to a spraying treatment machine for PU synthetic leather production and processing. Background Art
[0002] PU synthetic leather, also known as polyurethane synthetic leather, is a common imitation leather material. It is widely used in clothing, footwear, furniture, and automotive interiors because of its feel, softness, and durability close to natural leather. With the improvement of environmental protection and performance requirements, as well as the diversification of market demand, the production and processing technology of PU synthetic leather is also constantly developing and improving. Spraying treatment is one of the important links in the production of PU synthetic leather. It involves applying one or more coatings on the surface of synthetic leather to improve its appearance, texture, durability, or give it specific functional properties, such as waterproof, anti-fouling or flame retardant. This process often requires high precision and consistency to ensure that the sprayed PU synthetic leather meets strict quality standards.
[0003] In actual use, the blowing function can accelerate the curing process of the spray material and improve production efficiency. Without this function, the entire painting and drying process may take longer, thereby reducing the overall production efficiency. Without the heavy pressure wheel to apply additional pressure, the spray material and synthetic leather may not be tightly combined, resulting in material waste and wrinkles during the spraying process. The heavy pressure wheel can ensure that the spray material is spread evenly on the surface of the synthetic leather. The lack of this function may cause bubbles, wrinkles or other unevenness on the surface of the synthetic leather, affecting the appearance and performance of the product. The heavy pressure wheel helps to apply uniform pressure on the material to ensure the accuracy of the inkjet spray. Without this component, the spraying may deviate from the predetermined pattern, resulting in unstable product quality. For complex patterns that require fine spraying, it will become more difficult to achieve high-precision spraying without the assistance of a hot air blower and a heavy pressure wheel.

Specific embodiments
[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.
[0026] Please refer to Figures 1-5, the present utility model provides a technical solution: a spraying treatment machine for the production and processing of PU synthetic leather, a conveyor belt 1, inside which there are rolling-connected rollers 2. These rollers 2 ensure the smooth rolling of the conveyor belt, thereby ensuring the smooth conveyance of materials. Both the left and right ends of the rollers 2 penetrate through fifth fixing columns 20, which provide stable support points to ensure the fixation of the rollers 2 and the correct position of the conveyor belt 1. On one side of the fifth fixing column 20, there is a fixedly-connected first fixing block 3, which helps to strengthen the stability of the overall structure. On one side of the first fixing block 3, there is a fixedly-connected first fixing column 5, which is used to support and position other components. One end of the first fixing column 5 is fixedly connected to a third fixing block 6, and a hot air blower module 7 is fixedly connected to the third fixing block 6. The hot air blower module 7 is used to heat the materials to improve the spraying effect of the synthetic leather and at the same time blow the surface of the synthetic leather clean. At the bottom end of the hot air blower module 7, there is an air outlet 8, and the number of the air outlets 8 is seven, which is used to evenly distribute hot air to improve efficiency. On one side of the first fixing block 3, there is a fixedly-connected second fixing column 9, which provides additional support and structural stability. One end of the second fixing column 9 is fixedly connected to a fourth fixing block 10, and on both inner sides of the fourth fixing block 10, there are fixedly-connected rotating shafts 19. The rotating shafts 19 cooperate with the heavy pressure rollers 11 to apply pressure to ensure the tight combination of the materials and the sprayed materials. On one side of the first fixing block 3, there is a fixedly-connected third fixing column 12, which is connected to a fifth fixing block 13 to form a support structure for the storage tank 16. One end of the third fixing column 12 is fixedly connected to the fifth fixing block 13, and at the top end of the fifth fixing block 13, there is a storage tank 16, which stores the materials for spraying. A conveying pipe 17 penetrates through the top end of the storage tank 16, and this conveying pipe 17 is used to convey the spraying materials from the storage tank to the inkjet nozzles. At the bottom end of the storage tank 16, there is an inkjet nozzle 18, which is used to spray the materials onto the moving synthetic leather. The number of the inkjet nozzles 18 is several to meet the spraying requirements of different patterns. At the bottom end of the storage tank 16, there is a fixedly-connected sixth fixing block 15, which is connected to the fourth fixing column 14 to provide the stability and fixation of the storage tank. One end of the fourth fixing column 14 is fixedly connected to the third fixing block 6 to further strengthen the firmness of the structure.
[0027] The bottom end of the third fixing block 6 is fixedly connected to the second fixing block 4. The number of the second fixing blocks 4 is four, which increases the supporting area of the overall structure. The number of the first fixing columns 5 is two, forming a symmetrical structure to ensure the stability of the first fixing block 3. The first fixing column 5 and the third fixing block 6 cooperate to ensure the balance and symmetry of the overall structure. The air outlet 8 and the hot air blower module 7 cooperate to ensure that the spraying material is evenly heated. The number of the first fixing blocks 3 and the rollers 2 is two, forming a symmetrical structure to support the stable operation of the conveyor belt 1. The rotating shaft 19 and the fourth fixing block 10 cooperate to support the heavy pressure wheel 11 in the rotating system. The number of the heavy pressure wheels 11 is two, which cooperate with the conveyor belt 1 to ensure the stability of the material during the conveying process. The storage tank 16 cooperates with the fifth fixing block 13 and the sixth fixing block 15 to form a closed spraying material storage and conveying system. The inkjet port 18 and the bottom end of the storage tank 16 cooperate to ensure that the spraying material is accurately sprayed onto the synthetic leather.
[0028] Working principle: First, the PU synthetic leather to be spray-treated is placed flat on conveyor belt 1, which marks the start of the entire production process. The rolling system composed of roller 2 and the fifth fixed column 20 ensures that conveyor belt 1 can maintain smooth rolling under any load, achieving continuous, uniform, and unobstructed material transportation. During the transportation process, the hot air blower module 7 on the third fixed block 6 provides uniformly distributed hot air to the surface of the synthetic leather through its air outlet 8. This gentle heating not only helps improve the bonding force between the spray material and the synthetic leather surface but also effectively removes impurities and static electricity on the material surface, creating ideal cleaning conditions for the spraying process. While ensuring the stability of material transportation, the coordinated action of the rotating shaft 19 on the first fixed block 3 and the heavy pressure wheel 11 is crucial. They apply appropriate mechanical pressure to ensure that the material is tightly bonded to the spray material during transportation, avoiding affecting the final spraying quality due to sliding or misalignment. Immediately afterwards, the spray material is properly stored in the reserve tank 16 and efficiently transported to the inkjet nozzle 18 through the delivery pipe 17, ensuring continuous supply and uniform spraying of the spray material. The design distribution of the inkjet nozzle 18 ensures that the spraying process can cover the entire width of the synthetic leather, achieving precise and consistent pattern spraying. Each spraying has an important impact on the aesthetics and functionality of the synthetic leather surface, ensuring that the final product meets the needs of the market and consumers. In the overall structural design, multiple fixed blocks and fixed columns, such as the first fixed block 3, the third fixed block 6, the fifth fixed block 13, the sixth fixed block 15, etc., not only provide key support but also enhance the structural stability of the entire spraying processor. These components ensure that the machine can withstand repeated and high-intensity operations while reducing vibration and noise during operation. In addition, the symmetric structural design of the machine, such as the first fixed column 5, the air outlet 8, the first fixed block 3, etc., not only achieves balance aesthetically but also maximizes efficiency and spraying uniformity functionally. This symmetry demonstrates its importance during operation, ensuring consistency and predictability in the production process.
[0029] The embodiments of the present utility model have been described in detail above in conjunction with the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the knowledge scope of those of ordinary skill in the art to which it pertains, various changes can be made without departing from the gist of the present utility model.
