Description

Leather stretching dryer Technical Field The utility model relates to the technical field of leather processing, in particular to a leather stretching dryer. Background Leather is an animal skin which is not easy to decay and is denatured and obtained by physical and chemical processing such as dehairing and tanning. The leather is formed by tightly weaving natural protein fibers in a three-dimensional space, and the surface of the leather is provided with a special grain layer, has natural grain lines and luster and has comfortable hand feeling; In the leather processing process, the leather needs to be dried, a hot air dryer is needed in the drying process, however, when the leather is dried by the traditional hot air dryer, the shrinkage wrinkling condition is easily generated due to water loss, the extensibility of the leather surface is affected, the shrinkage condition of the leather can be affected, the final leather yield of the leather is affected, and the practicability is poor. Disclosure of utility model The present utility model is directed to a leather stretching dryer, which solves the above-mentioned problems. The technical scheme is that the leather stretching dryer comprises a lower machine plate, guide plates are fixedly arranged on two sides of the upper surface of the lower machine plate, a threaded screw rod is rotatably arranged in one guide plate through a bearing, a polished rod is fixedly arranged in the other guide plate, the threaded screw rod is a positive and negative screw rod, primary upright posts are sleeved on positive and negative threads of the threaded screw rod, the bottom ends of the two primary upright posts are in threaded connection with the threaded screw rod, two secondary upright posts symmetrical to the primary upright posts are slidably arranged on the polished rod, rotating rollers are rotatably arranged between the two opposite primary upright posts and the secondary upright posts through bearings, a rotating motor is fixedly arranged on the outer wall of one primary upright post through a fixing bolt, an output shaft of the rotating motor is fixedly connected with one rotating roller, and a hot air outer cover is covered in the middle of the upper surface of the lower machine plate. Preferably, one end of the threaded screw rod is fixedly connected with an output shaft of a servo motor, and the servo motor is fixedly installed on the outer wall of the guide plate through a bolt. Preferably, the upper surface of the top end of the hot air outer cover is fixedly provided with two symmetrically distributed fan motors through bolts, and the bottom end of an output shaft of each fan motor is fixedly provided with a hot fan. Preferably, a plurality of uniformly distributed heating rods are fixedly arranged below the hot air fan, and an outer shield is covered outside the hot air fan and the plurality of heating rods. Preferably, the lower surface of the bottom end of the outer shield is fixedly provided with an air outlet plate. Preferably, a plurality of equally spaced strip-shaped air outlets are formed in the outer surface of the air outlet plate. Compared with the prior art, the utility model has the beneficial effects that: According to the utility model, through the cooperation of the tightening structures, the leather tightening work can be carried out when the leather is dried, the phenomenon that the leather is retracted due to moisture loss during drying is avoided, so that the phenomenon that the outer surface of the leather is wrinkled can be effectively avoided, the surface ductility of the leather during drying processing is improved, the surface smoothness of the leather is ensured, the hot air drying processing quality of the leather can be effectively improved, and a good effect is achieved; Meanwhile, when the leather is stretched and dried, the leather is prevented from retracting, so that the condition of shortening the retracting length of the leather can be effectively avoided, the final leather yield of the leather is improved, and the use effect is effectively improved; The space between the two roller bodies of the rotary roller tightening structure has dynamic thread adjustability, so that the space can be dynamically adjusted according to the lengths of different leather, and the rotary roller tightening structure can be suitable for end-to-end leather tightening and drying of leather with different lengths, is more convenient and quick in structure use, is wider in size use range, and effectively reduces use limitation; According to the leather stretcher, one of the rotating rollers 7 can be driven to rotate through the rotating motor 8, when one of the rotating rollers 7 rotates, leather can be circularly and reciprocally conveyed between the two rotating rollers 7 through friction force action between the roller bodies and the leather, and through the circulation conveying of the leather conveying type, conveying type conveying conve
