Description

Technical Field

[0001] This utility model relates to the technical field of medical material transportation equipment, specifically to a sealed delivery device for medical materials. Background Technology

[0002] In the large-scale production and processing of medical materials, many types of medical components come into direct or indirect contact with drugs and the human body, placing extremely stringent requirements on cleanliness and sterility throughout the entire production process. Medical bottle caps, as a typical medical material, typically consist of an inner cap and an outer cap, which are injection molded separately using two independent injection molding machines. After processing, the inner and outer caps are each transported via an inclined conveyor to the same main conveyor line, from where they are transferred to subsequent assembly, cleaning, and sterilization processes. The requirements for surface cleanliness and sterility are particularly stringent for medical bottle caps. Dust, microorganisms, or debris remaining from the injection molding process adhering to their surface can contaminate drugs during subsequent use, thus threatening patient safety. Therefore, the inclined conveying process from injection molding completion to entry into the main conveyor line becomes a crucial step in ensuring the cleanliness of medical bottle caps. Currently, most tilting conveyor devices used for transporting medical bottle caps on the market are open or semi-open structures, which present numerous problems in practical applications. Existing tilting conveyors generally lack a dedicated sealing structure, leaving medical bottle caps completely exposed to the workshop environment during the tilting transport of inner and outer caps. Dust carried by airflow within the workshop, debris generated by equipment operation, and microorganisms introduced by personnel activities can easily adhere to the bottle cap surface. Even though some companies attempt to improve protection by covering the conveyor with simple baffles, significant gaps still exist between the baffles and the edges of the conveyor belts on both sides of the conveyor. Contaminants can still enter the transport path through these gaps, failing to form a complete sealed protection system. Meanwhile, some sealing structures adopt a fixed welding design. When bottle caps get stuck, conveyor malfunctions, or the conveying path needs to be cleared during the conveying process, staff cannot quickly open the sealing structure for inspection and maintenance. Often, the entire component needs to be disassembled, which not only seriously affects production efficiency but may also cause secondary contamination of the bottle caps during disassembly and reassembly.

[0003] Therefore, for the inclined conveying scenario of medical bottle cap inner and outer caps from two injection molding machines to the main conveyor line, there is an urgent need to propose a medical material sealing conveying device that can achieve full-process sealing to block contaminants and facilitate observation and maintenance. Utility Model Content

[0004] The purpose of this invention is to provide a sealed delivery device for medical materials, which can achieve full-process sealing to block contaminants and is easy to observe and maintain.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A medical material sealing and conveying device includes several inclined conveyors and several sealing covers connected end-to-end. Each inclined conveyor includes a frame and a conveyor belt, with several baffles on the conveyor belt. The frame has slots extending along the conveying direction on both sides. The bottom sides of each sealing cover are slidably and sealingly connected to the slots on both sides of the frame. A connecting sleeve is provided between adjacent sealing covers, with both ends of the connecting sleeve sealingly connected to two adjacent sealing covers, and the bottom sides of the connecting sleeve are slidably and sealingly connected to the slots on both sides of the frame. Furthermore, the three inclined conveyors are interconnected by a connecting cover. One end of the connecting cover is rotatably connected to a sealing cover plate adapted to the sealing cover of one of the inclined conveyors, and a pair of frame plates adapted to the frame of that inclined conveyor. The other end of the connecting cover is rotatably connected to a sealing cover plate adapted to the sealing cover of another inclined conveyor, and a pair of frame plates adapted to the frame of that inclined conveyor. The sealing cover extends into the interior of both ends of the connecting cover. The bottom end of the connecting cover has an opening facing the sealing cover of the third inclined conveyor.

[0006] Furthermore, the lower edge of the sealing cover plate is provided with a first sealing strip, and the lower edge of the frame plate is provided with a first frame sealing strip; inside the connecting cover, near its two ends, a pair of second sealing strips are provided for each side edge of the sealing cover extending into the two ends; the lower edge of the connecting cover in contact with the frame, and the side edges of the connecting cover in contact with the frame, are all provided with second frame sealing strips.

[0007] Furthermore, both of the aforementioned card slots are equipped with card slot sealing strips.

[0008] Furthermore, the connecting sleeve has bayonets on both sides of the side facing the conveyor belt, and a bayonet sealing strip is provided inside the bayonet.

[0009] Furthermore, the sealing cover includes a sealing cover body and a sealing cap disposed on the sealing cover body, the sealing cap being hinged to the sealing cover body; the sealing cap has an annular sealing groove around its perimeter on the side near the sealing cover body, and the sealing cover body has an annular sealing ridge corresponding to the annular sealing groove on the side near the sealing cap body.

[0010] Furthermore, an annular sealing strip is provided inside the annular sealing groove.

[0011] Furthermore, a latch is provided between the sealing cap and the sealing cover body, and the latch is located on the side of the sealing cover away from the hinge.

[0012] Furthermore, the sealing cover is equipped with a handle and an observation window.

[0013] Furthermore, both the sealing cover plate and the frame plate are rotatably connected to the connecting cover via torsion springs.

[0014] The beneficial effects of this utility model are: 1. This utility model, through the structure of "inclined conveyor + sealing cover connected end to end", combined with the sliding sealing connection between the sealing cover and the slots on both sides of the conveyor, and the sliding sealing design between the connecting sleeves at both ends of the sealing cover and the slots, forms a sealed space covering the entire inclined conveying process of medical bottle caps. This solves the problem of gap leakage in existing open or semi-open conveying devices, and effectively prevents dust, microorganisms and injection molding residues in the workshop environment from entering the conveying path.

[0015] 2. This utility model designs a connecting cover that connects three inclined conveyors, forming a complete structure of "main body sealing + connection sealing". This solves the problem of easy exposure when multiple machines are connected in existing devices. Ultimately, it forms a sealed space that covers the entire process of inclined conveying of medical materials and transfer between multiple machines, effectively blocking the entry of external dust and microorganisms, ensuring that the medical materials are clean and sterile throughout the entire process of conveying, and meeting the core requirements of sealed conveying in medical scenarios.

[0016] 3. This utility model uses a hinged connection between the sealing cover body and the sealing cap, and is fixed with a buckle. At the same time, the sealing cap and the sealing cover body cooperate through the cooperation of the annular sealing groove, the annular sealing ridge and the annular sealing strip. While ensuring the sealing effect at the top, the sealing cap can be quickly opened by opening the buckle without disassembling the whole assembly. This allows for handling of bottle cap jamming and accumulation problems that may occur during the conveying process, or for inspection, cleaning and routine maintenance of the conveyor interior. This greatly shortens the time spent on troubleshooting and maintenance and avoids production interruptions caused by downtime for maintenance. Attached Figure Description

Detailed Implementation

[0019] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0020] Example 1 like Figures 1 to 8 As shown, this embodiment discloses a medical material sealing and conveying device to solve the sealing and protection problem of medical bottle caps (including inner and outer caps) after being processed by injection molding machine 50 and conveyed at an angle to the main conveying line 40. This avoids the impact of dust, microorganisms and other contaminants on the cleanliness of the bottle caps, while also achieving smooth connection between multiple machines and convenient maintenance.

[0021] The device includes several inclined conveyors 10 and several sealing covers 20 connected end-to-end. The inclined conveyor 10 serves as a carrier for transporting medical bottle caps, comprising a conveyor belt 11 and slots 12 on both sides of the conveyor belt 11. The conveyor belt 11 is made of food-grade wear-resistant rubber, with evenly spaced baffles 13 on its surface along the conveying direction. The baffles 13 are rectangular protrusions integrally formed with the conveyor belt 11, effectively preventing bottle caps from sliding down the surface of the conveyor belt 11 due to gravity during inclined transport. Combined with the limiting effect of the slots 12 on both sides, this further prevents bottle caps from slipping or piling up. The inclination angle of the conveyor belt 11 can be set according to the workshop layout. The slots 12 are U-shaped grooves, with a depth adapted to the thickness of the bottom sides of the sealing covers 20. They are used for positioning and installing the sealing covers 20, providing stable support, and also assisting in limiting the bottle caps on both sides of the conveyor belt 11, preventing them from falling during inclined transport. To achieve a complete seal, both slots 12 are slidably and sealingly connected to the bottom sides of the sealing cover 20. The bottom sides of the sealing cover 20 are embedded in the slots 12 and tightly fitted to the inner wall, forming a preliminary side seal. Both ends of the sealing cover 20 are sealed and connected to connecting sleeves 30. The connecting sleeves 30 are rectangular frames with open ends, and their dimensions are consistent with the end faces of the sealing cover 20. They can be fixed to the end faces of the sealing cover 20 with bolts. The bottom sides of the connecting sleeves 30 are slidably and sealingly connected to the two slots 12 (i.e., the bottom is embedded in the slots 12 and fits against the inner wall). After several sealing covers 20 are connected in series with the connecting sleeves 30, they can completely cover the area of ​​the conveyor belt 11 of the inclined conveyor 10, forming a continuous sealed space and preventing external contaminants from entering from the sides of the conveyor belt 11 or the gaps between the sealing covers 20.

[0022] Multiple inclined conveyors 10 are interconnected via connecting covers 70. In this embodiment, three inclined conveyors 10 are provided to achieve unified transportation of the inner and outer caps of medical bottle caps. The two ends of the connecting cover 70 are respectively connected to the inclined conveyors 10 that transport the inner and outer caps, and its bottom opening leads to the third inclined conveyor 10 for centralized transportation. The connecting cover 70 is a rectangular cover with a width slightly larger than the width of the frame 14 of the inclined conveyor 10. One end of the connecting cover 70 is rotatably connected to a sealing cover plate 70 (fitting the end face of the sealing cover 20 of the previous conveyor) and two frame plates 72 (symmetrically distributed on both sides of the sealing cover plate 70 and fitted to the top of the frame 14) via a rotating shaft 73. The other end of the connecting cover 70 is also rotatably connected to a sealing cover plate 70 and two frame plates 72 (fitting the sealing cover 20 and frame 14 of the other conveyor). Both the sealing cover plate 70 and the frame plates 72 are connected to the rotating shaft 73 of the connecting cover 70 via torsion springs. The torsion springs are sleeved on the outside of the rotating shaft 73, so that the sealing cover plate 70 and the frame plates 72 are tightly attached to the surface of the sealing cover 20 or the frame 14, respectively.

[0023] The lower edge of the sealing cover plate 70 is fixed with a first sealing strip 63 by adhesive bonding, and the lower edge of the frame plate 72 is fixed with a first frame sealing strip 64. Inside the connecting cover 70, near both ends, corresponding to the two sides of the extending sealing cover 20, a pair of second sealing strips 65 are provided, fitting against the sides of the sealing cover 20. The second sealing strips 65 are bonded to the sealing strip mounting plate 74 located inside the connecting cover 70. The lower edge of the connecting cover 70 in contact with the frame 14, and the two sides of the connecting cover 70 in contact with the frame 14, are all fixed with second frame sealing strips 66 by adhesive bonding. The ends of the sealing covers 20 of the first two conveyors extend into the two ends of the connecting cover 70. The bottom end of the connecting cover 70 has a rectangular opening facing the sealing cover 20 of the third conveyor, ensuring that the inner and outer covers conveyed by the first two conveyors can fall into the sealing cover 20 of the third conveyor through the opening at the bottom end of the connecting cover 70.

[0024] To improve sealing performance, the two slots 12 are equipped with slot sealing strips 61 made of elastic silicone. When the bottom of the sealing cover 20 and the connecting sleeve 30 are embedded in the slots 12, the slot sealing strips 61 are compressed and deformed, filling the tiny gaps and improving the reliability of the side seal. At the same time, the connecting sleeve 30 has slots 31 on both sides facing the conveyor belt 11, and slot sealing strips are installed in the slots 31. When the connecting sleeve 30 is connected to the end face of the sealing cover 20, the bayonet sealing strip is squeezed between the end faces of the connecting sleeve 30 and the sealing cover 20, filling the tiny gap at the joint and completely sealing the gap between the connecting sleeve 30 and the sealing cover 20, preventing contaminants from entering the sealed space from the joint. At the same time, the bottom sides of the connecting sleeve 30 are slidably sealed to the two slots 12 respectively (that is, the bottom sides of the connecting sleeve 30 are embedded in the slots 12 and fit against the inner wall of the slots 12). After several sealing covers 20 are connected in series through the connecting sleeves 30 at the beginning and end, they can completely cover the area of ​​the conveyor belt 11 of the inclined conveyor 10, forming a continuous sealed space and blocking external contaminants from entering from the gaps between the sides of the conveyor belt 11 or the sealing covers 20.

[0025] The sealing cover 20 includes a sealing cover body 21 and a sealing cap 22 mounted thereon, which are hinged together by a hinge. The hinge is made of stainless steel and is fixed to the top edge of the sealing cover body 21 and one side edge of the sealing cap 22 by bolts to ensure structural stability. The sealing cap 22 can be flipped upward around the hinge axis, which makes it convenient for staff to inspect and maintain the inside of the sealing cover 20, or to deal with bottle cap jamming or accumulation problems, without having to disassemble the entire sealing cover 20. To ensure a tight seal at the top after the sealing cover 22 is closed, an annular sealing groove 23 is provided on the side of the sealing cover 22 near the sealing cover body 21, and an annular sealing ridge 24 (the size of which matches the annular sealing groove 23) is provided at the corresponding position on the sealing cover body 21. When the sealing cover 22 is closed, the annular sealing ridge 24 is embedded in the annular sealing groove 23 to form a preliminary top seal. An annular sealing strip 62 (made of elastic silicone, with a cross-section consistent with the annular sealing groove 23, and fixed by adhesive) is also provided inside the annular sealing groove 23. When the annular sealing ridge 24 is embedded, it compresses and deforms the annular sealing strip 62, filling the tiny gaps and preventing contaminants from entering from the joint between the sealing cover 22 and the sealing cover body 21, ensuring the integrity of the sealed space.

[0026] A latch 25 (located away from the hinge) is provided between the sealing cap 22 and the sealing cover body 21. The latch 25 is made of stainless steel and includes a latch seat fixed to the side wall of the sealing cover body 21 and a latch head fixed to the side wall of the sealing cap 22. After the sealing cap 22 is closed, the latch head engages with the latch seat to lock it in place, preventing the sealing cap 22 from being accidentally opened due to vibration. The latch 25 is also easy to operate and can be opened and closed manually. The sealing cap 22 is also equipped with a handle 26 and an observation window 27: the handle 26 can be fixed to the top of the sealing cap 22 with bolts for easy gripping and opening and closing; the observation window 27 is made of transparent tempered glass and is fixed to the pre-set window of the sealing cap 22 with sealant. The staff can observe the internal bottle cap conveying status (such as breakage, accumulation, jamming, etc.) in real time through the observation window 27 without opening the sealing cap 22, avoiding damage to the sealing environment and timely handling of faults to ensure continuous conveying. In practical applications, first assemble the sealing cover 20 according to the length of a single inclined conveyor 10: embed the bottom sides of the sealing cover 20 into the slots 12 of the frame 14 (press the slot sealing strip 61), fix adjacent sealing covers 20 with connecting sleeves 30 (press the slot sealing strip), close the sealing cover 22 (the annular sealing ridge 24 is embedded into the annular sealing groove 23 and the annular sealing strip 62 is pressed), and fasten the buckle 25 to lock; then install the connecting cover 70: fasten the sealing cover plates 70 and the frame plates 72 at both ends of the connecting cover 70 onto the sealing covers 20 of the first two conveyors and the frame 14 respectively, ensuring that the lower edge of the connecting cover 70 and the second frame sealing strips 66 on both sides are in contact with the frame 14, and that the bottom opening of the connecting cover 70 is aligned with the sealing cover 20 of the third conveyor. To further improve the sealing performance, the contact surface between the bottom of the connecting cover 70 and the third conveyor should also be provided with a bottom sealing strip.

[0027] After the device is started, the processed inner and outer covers are placed between the baffles of the conveyor belts 11 of the two inclined conveyors 10, and conveyed along the inclined direction to the connecting cover 70. Then, they fall through the bottom opening of the connecting cover 70 into the sealing cover 20 of the third conveyor, and finally reach the packaging station via the main conveyor line 40. During this process, the staff can monitor the conveying status through the observation window 27. When maintenance is required, the fastener 25 can be opened, the handle 26 can be grasped, and the sealing cover 22 can be flipped over to operate. The entire process ensures that the materials are in a sealed and clean environment.

[0028] In summary, this embodiment achieves a continuous protective structure by setting several sealing covers 20 in series on the inclined conveyor 10 and connecting each inclined conveyor 10 with a connecting cover 70. It also constructs a fully sealed space with sealing strips at all levels. At the same time, it optimizes operation and maintenance by using hinged sealing covers 22, buckles 25 and observation windows 27. This achieves clean protection for the inclined conveying of medical bottle caps and improves the ease of maintenance and flexibility of use of the device.

[0029] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
