Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cyclodextrin delivery, in particular to a cyclodextrin fluid delivery device. BACKGROUND

[0002] Cyclodextrin molecules have a special ring structure, with a hydrophobic cavity inside and hydrophilic hydroxyl groups on the outside. When cyclodextrin interacts with specific guest molecules (such as drugs, fragrances, pigments, etc.), the guest molecules can enter the hydrophobic cavity of the cyclodextrin to form host-guest inclusion complexes. This inclusion can change the physical and chemical properties of the guest molecules, such as increasing the solubility, stability, and bioavailability of the guest molecules. The cyclodextrin and its inclusion complex dispersed in a suitable solvent (such as water, organic solvent or mixed solvent) form a system with fluidity, which has both cyclodextrin inclusion properties and fluidity. It has important applications in food, medicine, cosmetics and other fields. In the production process of cyclodextrin fluid, a filling bottle containing cyclodextrin fluid is delivered by a delivery device.

[0003] In the prior art (publication number CN220431394U, named cyclodextrin fluid delivery device), a base is provided with a feeding mechanism, a conveyor belt mechanism and an adjusting mechanism. The feeding mechanism includes a stand, and a housing is arranged on the stand. A first motor is arranged on the base, and a rotating shaft of the first motor is provided with a rotating disc. The utility model has the purposes of conveniently and uniformly feeding cyclodextrin fluid filling bottles to the conveyor belt mechanism, and limiting the width of the cyclodextrin fluid filling bottles on the conveyor belt mechanism, which is beneficial to the delivery of the cyclodextrin fluid filling bottles.

[0004] The existing delivery device has only one delivery route. Once the delivery speed of the conveyor belt slows down, the products are prone to accumulate on the conveyor belt, and there is no effective shunting measure, which eventually causes the interruption of the entire delivery process and the stagnation of production. Moreover, for some cyclodextrin fluids with high concentration, the cyclodextrin fluid is prone to adhere and accumulate on the inner wall of the filling bottle during the delivery process. The traditional device lacks effective shaking or processing mechanism, which greatly reduces the uniformity and aesthetics of the products, and it is also difficult to accurately observe the amount of fluid in the filling bottle during subsequent liquid level inspection. SUMMARY
