Description

Technical Field

[0001] The utility model relates to the technical field of medical packaging, and particularly relates to an aluminum-plastic packaging device for an iodine solution protection cap. Background Art

[0002] In the medical device packaging industry, as an indispensable disinfection and protection component, the packaging quality of the iodine solution protection cap is directly related to the safety and actual application efficiency of the final product. Traditional manual or semi-automatic packaging methods are limited by bottlenecks such as low efficiency, insufficient encapsulation tightness, and susceptibility to contamination, and are difficult to meet the increasingly demanding production and quality control requirements. In view of the above problems, technicians in the industry have actively explored and practiced a number of technological innovations. One of the landmark achievements is the iodine solution protection cap assembly and filling machine disclosed in Chinese Patent CN203889096U. This device cleverly combines a hundred-level laminar flow hood environment to achieve a full-automatic production process from raw material feeding, precise filling to component assembly, significantly improving production efficiency, and effectively ensuring the purity and consistency of the product, solving problems such as complex traditional production processes and low efficiency. However, despite the above progress, the packaging link of the iodine solution protection cap still faces challenges: in the actual packaging process, the protection cap is prone to problems such as jamming, unstable falling, and inconsistent directions, which not only affect the overall efficiency of the packaging line, but also pose a potential threat to the quality stability of the finished product. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is: to overcome the deficiencies of the prior art and provide an aluminum-plastic packaging device for an iodine solution protection cap.

[0004] The technical solution adopted by the utility model is as follows:

[0008] The upper cover pressing mechanism includes a pressing device II, which is arranged above the bowl-shaped bottom shell; the upper cover packaging material is led out from the upper cover feeding roll, turns through the guiding wheel I and then passes through the pressing device II. The pressing device II presses the upper cover packaging material onto the bottom shell packaging material to realize the plastic sealing of the iodine solution protection cap and form a semi-finished product.

[0009] The cutting and collecting mechanism includes a marking and cutting device and a waste collecting roll, which are arranged above the semi-finished product and are used to mark and cut the periphery of the semi-finished product in the semi-finished product area so that it is separated from the pressed bottom shell packaging material and the upper cover packaging material to form a finished product; the remaining waste is turned through the guiding wheel II and collected on the waste collecting roll.

[0010] The storage and conveying mechanism includes a storage bin and an inclined channel. The inclined channel is arranged towards the direction where the finished product falls on the packaging assembly line, and the bottom is connected to the conveying assembly line to realize the orderly storage and automatic conveying of the finished product.

[0011] This technical solution constructs an efficient and automated aluminum-plastic packaging device for iodine solution protection caps by integrating multiple mechanisms such as feeding combination, vision inspection, upper cover pressing, cutting and collection, and storage and transportation. Its aim is to achieve full automation from raw material feeding to finished product output, ensuring the cleanliness, accuracy, and efficiency of the packaging process. Specifically, the spiral vibrating disk feeds the iodine solution protection caps into the conveying channel in an orderly manner through vibration; the vibration frequency and intensity need to be precisely controlled to ensure that the iodine solution protection caps enter the channel stably and continuously, while avoiding jamming or excessive sliding; the conveying channel is inclined to facilitate the downward sliding of the iodine solution protection caps by using gravity; a transparent acrylic plate covers the conveying channel, which on the one hand plays a role in dust prevention, preventing external particles or pollutants from invading the packaging process, and on the other hand also facilitates the operator's visual observation; the pressing device I presses the bottom shell packaging material into a bowl-shaped bottom shell.

[0014] In this technical solution, a blowing nozzle, a solenoid valve, and a reciprocating plate are introduced into the falling channel. By using intermittent high-speed airflows and mechanical reciprocating motions, the problem of material jamming of the iodine solution protection cap in the conveying channel is effectively solved, promoting the smooth sliding of the protection cap and improving the continuity of the packaging process.

[0015] According to an embodiment of the present invention, a card slot matching the conveying channel is provided on the reciprocating plate, and its side is synchronously driven by a cylinder to perform reciprocating motions; when the card slot is aligned with the conveying channel, the iodine solution protection cap falls into the bowl-shaped bottom shell; when staggered, the falling of the iodine solution protection cap is blocked until the bowl-shaped bottom shell reaches the designated position.

[0016] This technical solution realizes precise control of the falling of the iodine solution protection cap through a reciprocating plate with a card slot and its cooperation with the conveying channel, ensuring that the protection cap accurately falls into the bowl-shaped bottom shell when the latter reaches the designated position, avoiding falling under unprepared circumstances, and guaranteeing the smooth progress of the packaging process.

[0021] According to an embodiment of the present invention, the upper surface of the conveying channel is covered with a transparent acrylic plate, which is fixed by bolts and closely fits with the edge of the conveying channel to prevent dust from entering; the blowing port is inclined downwardly opened on the transparent acrylic plate.

[0022] This technical solution not only enhances the dust-proof effect but also optimizes the blowing effect by covering the upper surface of the conveying channel with a transparent acrylic plate and inclinedly opening the blowing port, improving the stability and accuracy of the falling of the iodine solution protection cap.
