In practical application, the second motor 23 is driven to drive the first gear 20 to rotate, so that the first gear 20 drives the second gear 21 to rotate, the rotation speed of the second gear 21 is slow, and the second gear can be specifically designed by a user, because the slow rotation of the collecting basin 18 can be better adapted to the falling of the molecular sieve membrane 13, the molecular sieve membranes 13 falling into the collecting basin 18 can be prevented from contacting each other in a certain time, and thus the capability of preventing the molecular sieve membrane 13 from falling can be improved; the collecting basin 18 and the second gear 21 are designed into a separated combination, so that a plurality of collecting basins 18 can be collected simultaneously and enter an activation chamber in the subsequent activation heating process of the molecular sieve membrane 13, and the activation efficiency of the molecular sieve membrane 13 is improved;
further, the position of the collecting basin body 18 can be adjusted to a certain extent by the arrangement of the second telescopic component 22, so that the collecting basin body 18 can be more matched with the falling molecular sieve membrane 13 to more accurately control the falling position of the molecular sieve membrane 13 in the collecting basin body 18, and the stability of the molecular sieve membrane 13 is improved;
as shown in fig. 1 and 8, the stopper 19 is a truncated cone with a cover, and a vertical distance d exists between the large diameter of the truncated cone and the falling point of the molecular sieve membrane 13 in the collecting basin 18, because of the vertical distance d, when the molecular sieve membrane 13 falls into the collecting basin 18, the stopper 19 can reduce the probability of reverse dumping of the molecular sieve membrane 13, so that the molecular sieve membrane 13 can be guaranteed to lean against the side wall of the collecting basin 18 after falling.
Working principle: when the molecular sieve membrane 13 is placed on the wheel belt, the hydrophilic fabric absorbs moisture outside the molecular sieve membrane 13;
meanwhile, when a plurality of molecular sieve membranes 13 move onto the first conveyor belt 15, the friction force of the first conveyor belt 15 is received, the extrusion force of the dehydration ends of the dehydration plates 16 at two sides is received, so that the molecular sieve membranes 13 gradually rotate in the moving process until the molecular sieve membranes move into the collecting basin 18 in a parabolic manner from the acute angle end of the triangle, during which, the air outlet pipeline 34 blows out hot air, on one hand, the hot air can pass through the internal space of the molecular sieve membranes 13, the dehydration efficiency of the molecular sieve membranes 13 is improved, and on the other hand, the air suction effect of the air inlet pipeline 35 can also recover the hot air blown out by the air outlet pipeline 34 and simultaneously take away the water vapor on the first conveyor belt 15, so that the drying of hydrophilic fabrics is accelerated, and the continuous water absorption capacity of the first conveyor belt 15 is improved;
when the molecular sieve membrane 13 contacts with the bottom surface of the collecting basin 18, the whole molecular sieve membrane 13 is inclined towards the side surface of the collecting basin 18, a soft cushion is arranged in the collecting basin 18, the surface of the soft cushion is rough, and the soft cushion sags when the molecular sieve membrane 13 contacts, so that the molecular sieve membrane 13 has a supporting point on the bottom surface and the side wall of the collecting basin 18, the probability of occurrence of the condition that the molecular sieve membrane 13 leans down after leaning on the collecting basin 18 can be reduced, and the two supporting points support the molecular sieve membrane 13, so that air flow can flow in the middle and the outer side of the molecular sieve membrane 13, and the molecular sieve membrane 13 can lean on the side wall of the collecting basin 18 along with the continuous collection of the molecular sieve membrane 13 by a collecting mechanism, so that the molecular sieve membrane 13 is heated uniformly when the molecular sieve membrane 13 is subjected to high-temperature activation treatment later.
Further, the first conveyor belt 15 may include two parallel sub-conveyor belts, and the two sub-conveyor belts respectively have mutually independent control units, if the molecular sieve membrane 13 is horizontally arranged and clamped on the dewatering end of the dewatering plate 16, the speeds of the two sub-conveyor belts can be manually adjusted, so that the two ends of the molecular sieve membrane 13 are subjected to friction forces in different directions, the direction of the molecular sieve membrane 13 can be changed, and the molecular sieve membrane 13 can be sent into the collecting basin 18 again by adjusting the two sub-conveyor belts.
