[0001] The invention relates to the technical field of drying, in particular to a drying device for processing TPU artificial leather. Background Art

[0002] TPU artificial leather (thermoplastic polyurethane artificial leather) is a synthetic leather material made of thermoplastic polyurethane (TPU) as the main raw material. It has both the processability of plastic and the elasticity of rubber. It is an upgraded substitute for traditional PVC artificial leather and PU synthetic leather. Halogen-free flame-retardant TPU can also replace soft PVC to meet the environmental protection requirements of more and more fields. At the same time, it has many excellent functions such as high waterproofness and moisture permeability, windproof, cold-proof, antibacterial, mildew-proof, warmth retention, UV resistance and energy release. Among them, TPU artificial leather is widely used. In the production process of TPU artificial leather, it will be dried after washing. However, in the current TPU artificial leather processing and drying device, although a hot air circulation device is provided inside the device to increase the drying efficiency during use, the pipeline on the hot air circulation device lacks dehumidification function, which makes the hot air re-sent into the device have a high humidity, affecting the drying efficiency of the TPU artificial leather inside the device.

[0003] The existing TPU artificial leather processing drying device has insufficient coverage during the material drying process, resulting in uneven drying, which affects the quality of subsequent products.

The exhaust pipe is arranged on both sides of the inner wall of the composite body to increase the air supply area and improve the material drying efficiency. The U-shaped pipe is used to connect the components in series to facilitate the flow of air. Therefore, when the winder winds the material, the material does not stick to the components, ensuring that the airflow fully covers the surface of the material to avoid affecting the local drying effect.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] The first embodiment, as Figures 1 to 5 As shown, the present invention provides a technical solution: a drying device for TPU artificial leather processing, comprising a composite mechanism 1, a cooling mechanism 3 is fixedly connected to one side of the outside of the composite mechanism 1, and a processing mechanism 2 is slidably connected to the inside of the composite mechanism 1; The composite mechanism 1 includes a composite body 11, a hot air blower 12 is fixedly connected to the top of the composite body 11, an exhaust pipe 13 is connected to a pipe on one side outside the hot air blower 12, a U-shaped pipe 14 is fixedly connected to the top of the two exhaust pipes 13, an unwinder 15 is fixedly connected to one side outside the composite body 11, a winder 16 is fixedly connected to the side of the composite body 11 away from the unwinder 15, a slide rail 17 is fixedly connected to the side of the inner wall of the composite body 11 close to the exhaust pipe 13, the outer side of the processing mechanism 2 is slidably connected to the outer side of the slide rail 17, the outer side of the slide rail 17 is slidably connected to a cleaning mechanism 19, and a roller mechanism 18 is fixedly connected to the top of the inner wall of the composite body 11. The material is placed on the unwinder 15, and one end is placed on the winder 16. The winder 16 rotates to drive the material to move continuously, so that the material is kept in a continuous drying operation. The material passes through the composite body 11, and the hot air blower 12 transmits air to the exhaust pipe 13. The exhaust pipe 13 transmits hot air to the inside of the composite body 11, so as to achieve the drying operation of the material. The exhaust pipe 13 is arranged on both sides of the inner wall of the composite body 11 to increase the air supply area and improve the material drying efficiency. The U-shaped tube 14 is used to connect the components in series to facilitate the flow of air. Therefore, when the winder 16 winds up the material, the material does not stick to the components, ensuring that the airflow fully covers the surface of the material to avoid affecting the local drying effect. The material contacts the roller mechanism 18 during the winding process, so as to facilitate the leveling of the material surface and avoid the overlap of materials affecting the drying efficiency.

[0022] The roller mechanism 18 includes a roller support 181, a roller rod 182 is fixedly connected between the opposite surfaces of the roller support 181, a square block 183 is fixedly connected to the top of the roller support 181, a square spring 184 is sleeved on the outer side of the square block 183, a square shell 185 is slidably connected to the outer side of the square block 183, and the top of the square shell 185 is fixedly connected to the top of the inner wall of the composite body 11. The surface of the material passes through the middle of the roller rod 182, so as to maintain the stability of the material during the movement process, so that the surface of the material is fully in contact with the airflow, and the drying efficiency is improved. Secondly, the movement stroke of the material is extended, so as to improve the operation efficiency. At the same time, the activity space of the material surface is limited to avoid the material from folding during the operation process, which affects the product quality and drying effect. During the operation process, the friction between the material and the components is easy to generate vibration.

After a long period of operation or liquid and impurities on the surface of the material are easily adsorbed on the surface of the component, which can easily cause blockage to the component, thereby affecting the exhaust effect. Therefore, the sliding block 21 slides on the outside of the slide rail 17 to make the column block 23 scrape the outside of the exhaust pipe 13, so as to clean the impurities on the surface of the component, reduce the accumulation of impurities, keep the exhaust of the component smooth, and keep the equipment drying. The rubber block 24 is set on the outside of the column block 23. As the column block 23 rotates with the friction of the component surface, the rubber block 24 scrapes the holes on the outside of the exhaust pipe 13, which has a certain cleaning effect on the holes of the component, further improves the cleaning effect, enriches the cleaning details, and reduces the probability of component blockage.

The cooling liquid enters the pipe shell 341 from one side of the butt pipe 342. The spiral block 343 adopts a spiral structure, which promotes turbulence effect through the spiral structure, forms spiral flow, generates centrifugal force, and increases the turbulence of the flow field, thereby improving the heat exchange efficiency, and at the same time plays a certain anti-blocking and scaling effect. When the fluid in a single channel passes through the impurity deposition area in the flow channel, the flow rate will be relatively increased, and the impurities are easily washed away, playing a self-cleaning role, and playing a certain protective effect on the equipment.

After the liquid enters the pipe shell 341, it impacts the arc paddle plate 3447, and the arc paddle plate 3447 increases the contact area with the fluid, thereby improving the rotation efficiency, so that the shaft block 3448 drives the connecting bracket 3442 to rotate inside the annular frame 3443, and the friction block 3445 rubs the inner wall of the pipe, thereby reducing the precipitation of impurities, reducing impurity scaling, and preventing excessive accumulation of impurities, thereby affecting the flow of liquid and preventing the subsequent cooling effect from being affected. Secondly, by opening a semi-arc groove 3446, the friction against the inner wall of the pipe is increased, the friction against the inner wall is improved, and the scratch cleaning effect is further improved, reducing impurity scaling.

[0030] During use, the staff places the material on the unwinder 15, and one end of the material is placed on the winder 16. At the same time, the surface of the material passes through the roller mechanism 18, and then the hot air blower 12 is started to generate hot air to facilitate the subsequent drying of the material.

The material is cooled to facilitate subsequent operations and prevent damage to the surface of the material. The surface of artificial leather is soft at high temperatures, and is easy to adhere to dust, foreign matter and be scratched. After cooling, the surface hardness increases, which can effectively avoid damage in subsequent processing, keep the surface smooth, and accelerate the shaping of the liquid inside the material. During the drying operation of the composite mechanism 1, dust impurities or liquid inside the material are easily scattered inside the composite mechanism to avoid damage to the equipment and affect the drying effect. The surface of the exhaust pipe 13 is rubbed and scratched by the processing mechanism 2, thereby achieving a cleaning effect on the surface of the component, avoiding excessive accumulation of impurities, reducing impurity scaling, avoiding blockage, affecting the gas flow effect, and extending the service life of the component.
