Description

Technical Field

[0001] The utility model relates to the technical field of automatic drying devices, in particular to an automatic drying device for breathable synthetic leather. Background Art

[0002] Synthetic leather is a plastic product that simulates the composition and structure of natural leather and can be used as a substitute for it. It is usually made of an impregnated non-woven fabric as a mesh layer and a microporous polyurethane layer as a grain layer. Both the front and back sides are very similar to leather and have a certain degree of air permeability. It is closer to natural leather than ordinary artificial leather and is widely used in the manufacture of shoes, boots, luggage, balls, etc. Some synthetic leathers need to be dried using a drying device during the production process.

[0003] In the prior art, the drying process generally involves contacting one side of the synthetic leather with a drying device and drying it. Since there is a certain amount of moisture inside the breathable synthetic leather, it is difficult for this drying device to completely dry the breathable synthetic leather at one time, so it needs to be turned over and dried multiple times. The drying process is relatively cumbersome, and if the humidity in the drying equipment is too high and not handled, the drying efficiency will be reduced. Utility Model Content

[0004] The utility model aims to provide an automatic drying device for breathable synthetic leather, which can first directly heat and evaporate the moisture on the surface of the synthetic leather, then dry it with hot air through a dryer, and recycle the blown hot air to save heat sources, while reducing the humidity of the air in the drying box to achieve better drying efficiency.

[0005] To achieve the above-mentioned purpose, an automatic drying device for breathable synthetic leather is provided, comprising: a drying box, a drying pipe is fixedly connected to the bottom of the inner cavity of the drying box, a heating plate is arranged inside the drying pipe, an air supply pipe is fixedly connected to the bottom of the drying pipe, an air outlet pipe is arranged above the drying pipe, the air outlet pipe is fixedly connected to the top of the drying box, and the air outlet pipe extends to the outside of the drying box, an exhaust fan is fixedly connected to the inner end of the air outlet pipe, the outer end of the air outlet pipe is fixedly connected to the air supply pipe, and the air outlet of the air outlet pipe is located inside the air supply pipe, two rollers are arranged in the middle of the left side of the inner cavity of the drying box, and both ends of the rollers are rotatably connected to the drying box, a belt is slidably connected to the roller, a heating roller is fixedly connected to the inside of the roller, and a humidity sensor is fixedly connected to the right side of the drying box.
