Description

Technical Field

[0001] The utility model belongs to the technical field of drying devices, in particular to a drying device for synthetic leather production. 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 material 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 production of shoes, boots, bags and balls. In the process of producing and processing synthetic leather, it needs to be washed, and the washed synthetic leather needs to be dried. The existing synthetic leather drying process is to pass through an oven for drying. If the drying time is too long, it will extend the processing time and reduce the processing efficiency. At the same time, it will also affect the surface of the synthetic leather. If the drying time is too short, there is a situation of not drying. Therefore, in view of the above problems, it is now necessary to improve it. Utility Model Content

[0015] Depend on Figures 1 to 3 The utility model includes a drying box 1, an operation port 2 is provided on one side of the drying box 1, two sealing doors 3 are rotatably installed inside the operation port 2, through grooves 4 are symmetrically provided in the middle of both ends of the drying box 1, first conveying rollers 5 are rotatably installed in the middle of both ends of one side of the drying box 1, second conveying rollers 6 are rotatably installed at the upper and lower parts of one side of the drying box 1 at equal distances, an inverted U-shaped air pipe 7 is fixedly installed on one side of the drying box 1, air pipes 8 are equidistantly and staggeredly installed on the upper and lower parts of the inverted U-shaped air pipe 7, air nozzles 9 are evenly and evenly fixedly installed on the surface of the air pipe 8, a water receiving cover 10 is fixedly installed on one end of the drying box 1, and one end of the drying box 1 and located at the upper and lower parts of the through grooves 4 are A wiper 11 is installed, and a drain pipe 12 is fixedly connected to the bottom of the water receiving cover 10; the two wipers 11 each include a fixed plate A1101, and the two fixed plates A1101 are symmetrically fixedly connected to the middle of one end of the drying box 1, and one end surface of the two fixed plates A1101 is rotatably connected to a rotating plate 1102, and a spring 1104 is fixedly connected between one side of the rotating plate 1102 and one side of the fixed plate A1101 at an equal distance, and the opposite ends of the two rotating plates 1102 are fixedly connected to a rubber wiper sleeve 1103, and the opposite ends of the two rubber wiper sleeves 1103 are connected. A transmission roller 15 is rotatably installed on one side of the top of the water receiving cover 10, so that the water on the surface of the synthetic leather can be effectively scraped off;

[0016] The synthetic leather is passed through between the two rubber wiper sleeves 1103 by the driving roller 15. When passing through, one of the rotating plates 1102 is squeezed so that one of the rotating plates 1102 drives the rubber wiper sleeve 1103 thereon to move and compress the spring 1104. Then, one end of the synthetic leather passes through the surface of the rubber wiper sleeve 1103 on the other rotating plate 1102 and extends to the inside of the drying box 1 through one of the through slots 4. Then, one of the rotating plates 1102 is released. Through the elastic restoring force of the spring 1104, one of the rotating plates 1102 drives the rubber wiper sleeve 1103 thereon to cooperate with the rubber wiper sleeve 1103 on the other rotating plate 1102 to contact the two side surfaces of the synthetic leather. Then, the first conveying roller 5 and the second conveying roller 6 are used to make the synthetic leather pass between them in a continuous inverted S shape and finally extend to the outside of the drying box 1 through another of the through slots 4.

[0017] When the synthetic leather moves, it passes between the two rubber wiper covers 1103 and the friction of the two rubber wiper covers 1103 can scrape off the water on both sides of the synthetic leather. Finally, the water flows into the inside of the water receiving cover 10 and is discharged through the drain pipe 12.

The bottom of the duct 14 extends to the interior of the drying box 1 and is fixedly connected to the inverted U-shaped air pipe 7, so as to provide warm air for drying;

[0019] When the synthetic leather moves inside the drying box 1 via the first conveying roller 5 and the second conveying roller 6, the heater 13 is started to generate warm air which is conveyed to the inside of the inverted U-shaped air duct 7 via the duct 14, and then conveyed to the inside of the air delivery pipe 8 and blown out via the air nozzle 9, so that the warm air heats and dries both sides of the moving synthetic leather.

[0020] Two pairs of fixed plates B16 are fixedly connected to the middle of the other side of the drying box 1, and a rotating shaft 17 is rotatably connected between the two pairs of fixed plates B16. A clamping rubber roller 18 is fixedly connected to the middle of the two rotating shafts 17. A meshing gear 19 is fixedly connected between one end of the two rotating shafts 17 at the joint of the surfaces of the two clamping rubber rollers 18. A motor 20 fixedly connected to the other end of one of the rotating shafts 17 is installed on one side of one of the fixed plates B16, so as to provide power for the transportation and movement of the synthetic leather;

[0021] When the synthetic leather extends from another through groove 4 to the outside of the drying box 1, the synthetic leather is clamped between the two clamping rubber rollers 18, and then the motor 20 is started, and then the two rotating shafts 17 are rotated relatively through two meshing gears 19, and the relatively rotating rotating shafts 17 will drive the two clamping rubber rollers 18 to rotate, and the rotation of the two clamping rubber rollers 18 will squeeze and clamp the synthetic leather and pull the synthetic leather to move, so that the synthetic leather can be effectively transported and moved.

[0022] The drying device for synthetic leather production has a structure that integrates water removal and drying, and can first scrape off the residual water of the synthetic leather after cleaning before drying, and then dry the dewatered synthetic leather, so that the quality of the synthetic leather can be ensured to be unaffected while ensuring drying. At the same time, the drying device has a simple structural design, is convenient to use and operate, and has stable and reliable water removal and drying processes, and its performance can meet the use requirements of synthetic leather production and processing.
