Description

Technical Field

[0001] The utility model belongs to the technical field of drying mechanisms, and in particular relates to a medical phosphorylcholine coating drying mechanism. Background Art

[0002] Phosphorylcholine coating is to spray a layer of phosphorylcholine film on the surface of medical stent or balloon catheter using ultrasonic spraying technology to increase the anti-coagulation effect of medical stent or balloon catheter. After spraying, it is dried in a drying tunnel mechanism.

[0003] The existing medical phosphorylcholine coating drying mechanism is composed of a drying rack, a conveyor belt assembly and a drying cover assembly. The drying cover assembly is connected to the hot air duct to blow hot air into the drying mechanism to dry the medical stents and other equipment coated with phosphorylcholine in the mechanism. However, there are the following defects:

[0004] (1) When the drying mechanism is used to dry the phosphorylcholine coating on the surface of medical equipment, the medical equipment coated with phosphorylcholine is placed on the conveyor belt assembly of the drying mechanism, and is transported to the interior of the drying cover assembly through the conveyor belt assembly. The drying cover assembly releases drying high-temperature gas and cooperates with the drying electric heating plate and other structures to achieve the drying treatment of the coating. However, during the drying process, since the conveyor belt assembly is partially exposed to the outside world, dust and debris are easily attached to the belt surface, and the dry coating will also adhere to the conveyor belt surface. If it is not cleaned in time, when the coating to be dried is placed in the subsequent sequence, the dirt on the belt surface is easy to adhere to the coating and affect the protective effect of the coating on the medical equipment. For this reason, we propose a medical phosphorylcholine coating drying mechanism. Utility Model Content

[0005] The purpose of the utility model is to provide a medical phosphorylcholine coating drying mechanism to solve the problem that when the medical phosphorylcholine coating drying mechanism proposed in the above background technology is in use, the debris attached to the surface of the conveyor belt used to transport the drying coating structure cannot be cleaned in time, and adheres to the coating, affecting the protective effect of the medical device coating.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a medical phosphorylcholine coating drying mechanism, comprising a drying frame, a belt roller drive assembly is arranged inside the drying frame, a conveyor belt is installed on the belt roller drive assembly, a drying cover assembly is arranged on the top of the drying frame, mounting frames are respectively fixed at both ends of the drying frame, an assembly cylinder is fixed at the center of the surface of the mounting frame by inlaying, a connecting column is arranged inside the assembly cylinder, a cleaning frame is fixed at one end of the connecting column, bristles are fixed on the surface of the cleaning frame, the ends of the bristles are in contact with the surface of the conveyor belt, a guide hole is opened on the surface of the mounting frame, a guide rod is passed through the inside of the guide hole, and one end of the guide rod is fixed to the surface of the cleaning frame.

[0007] Preferably, a spring is provided at the other end of the connecting column, and the spring is located inside the assembly cylinder.

[0008] Preferably, a limiting hole is provided on the side wall of the connecting column, a stopper is provided inside the limiting hole, and the stopper is fixed on the inner wall of the assembling cylinder.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] (1) Through the designed mounting frame, assembly tube, connecting column, bristles, cleaning frame, guide hole and guide rod, the cleaning frame equipped with bristles is assembled to the mounting frame through the assembly tube and the connecting column, and the guide rod is inserted into the guide hole to support and guide the cleaning frame. The mounting frame is fixed at both ends of the utility model, and the ends of the bristles fit the surface of the conveyor belt. When the conveyor belt is in conveying operation, the surface passes through the position of the bristles, and the bristles clean the remaining coating and debris on the surface of the conveyor belt in time to prevent dirt from adhering to the coating surface and affecting the coating protection effect. The designed spring generates elastic force on the connecting column at all times. The extrusion effect causes the connecting column to push the cleaning frame to ensure that the end of the bristle is always in close contact with the surface of the conveyor belt to avoid wear and tear that may affect the cleaning effect of the belt surface. The designed block and limit hole can prevent the connecting column from falling off the assembly tube. The designed threaded holes, studs and movable plates can be used to screw the studs, adjust the threads of the studs and threaded holes, and adjust the position of the movable plate in the assembly tube to adjust the degree of spring compression so that it can achieve the best extrusion elastic force on the connecting column. The designed ball bearings can play a lubricating role to avoid wear between the studs and the surfaces of the movable plate. BRIEF DESCRIPTION OF THE DRAWINGS
