Description

Technical Field

[0001] The present invention relates to the technical field of conveying devices, and in particular to a sterile article conveying device. Background Art

[0002] Sterile article conveyor is a device used to safely and effectively transfer sterile articles in a sterile environment. It is commonly found in hospitals, laboratories, pharmaceutical factories and other places where sterile conditions need to be maintained. This type of device can prevent bacteria, viruses and other contaminants from entering the conveyed articles, thereby ensuring the sterility of the articles.

[0003] The sterile article conveying device of the prior art generally adopts the form of conveyor belt for conveying. For example, when the sterile articles that have been cleaned, disinfected and packed with sterile cloth are conveyed to a sterile workshop, a conveyor belt is needed for conveying. However, when the conveyor belt of the prior art is used to convey sterile articles, the surface of the conveyor belt needs to be disinfected and sterilized regularly, because bacteria will inevitably adhere to the surface of the conveyor belt that has been running for a long time. However, when cleaning with the prior art, the conventional operation is to manually spray disinfectant alcohol onto the surface of the conveyor belt, and then wipe it with a sterile cloth manually. This undoubtedly increases the labor intensity during manual cleaning and is very inconvenient to clean. Therefore, the present application provides a sterile article conveying device to meet the needs. Summary of the invention

[0010] Optionally, an air inlet is provided at the right edge of the front side of the liquid storage bag near its top, an air inlet pipe is fixedly connected to the air inlet, and a one-way air inlet valve is installed on the air inlet pipe. A liquid inlet is provided at a position in the middle of the top end of the liquid storage bag near its front side, an injection pipe is fixedly connected to the liquid inlet, and a sealing cover is also threadedly connected to the top of the injection pipe, and the injection pipe is used to add medical disinfectant and sterilization alcohol to the interior of the liquid storage bag.

[0011] Optionally, the top ends of the air storage bag and the liquid storage bag are fixedly connected to the same top pressure plate, and both ends of the top pressure plate are fixedly connected to a lifting plate with an I-shaped cross-section, and the two support frames are provided with lifting channels that are adapted to the shape of the lifting plates, and the two lifting plates are rotatably connected with input pipes at positions close to their tops, and the two ends of the input pipes that are separated from each other are fixedly connected to the rotating end of a rotating joint, and the two ends of the rotating joints that are separated from each other are fixedly connected to hoses through inverted L-shaped connecting pipes, and the two inverted L-shaped connecting pipes are fixedly connected to the outer wall of the lifting plate through fixed blocks, and the bottom ends of the two hoses are respectively extended through L-shaped connecting pipes to be connected to the interior of the air storage bag and the liquid storage bag.

[0012] Optionally, a same hollow cylinder is fixedly connected to the outer sides of the opposite ends of the two input tubes, a sealing cylinder is fixedly connected to the inner wall of the hollow cylinder close to the end of the right input tube, a movable inner cylinder is provided on the outer sliding sleeve of the sealing cylinder, the left and right ends of the movable inner cylinder are respectively closed and open, a groove is provided at the center of the outer side of the left end of the movable inner cylinder, a corrugated telescopic airbag is fixedly connected in the groove, and one end of the corrugated telescopic airbag away from the groove is fixedly connected to the inner wall of the left end of the hollow cylinder.

The outer periphery of the sealing cylinder is also provided with a plurality of springs arranged in a circular array, and the left ends of the plurality of springs are fixed to the right end of the movable inner cylinder.

[0015] Optionally, a plurality of conical holes are formed on the outer side of the movable inner cylinder, a plurality of straight holes are formed on the outer side of the hollow cylinder, and absorbent cotton is fixedly connected to the outer side of the hollow cylinder.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects:

[0017] In the above scheme, by setting up a liquid storage bag and an air storage bag, and cooperating with a plurality of I-shaped spring pieces inside both, on the one hand, the absorbent cotton can be continuously and tightly fitted to the bottom of the conveyor belt with the help of the elastic force of the plurality of I-shaped spring pieces, so that the cleaning and sterilization effect is better. On the other hand, the friction between the conveyor belt and the water-absorbing surface is increased, so that the conveyor belt can drive the absorbent cotton to rotate effectively during the conveying process, and better clean and sterilize the surface of the conveyor belt.

[0018] During the operation of the conveyor belt, the absorbent cotton is intermittently squeezed by a plurality of spaced protrusions, so that the absorbent cotton drives the hollow cylinder downward, and the two inverted L-shaped connecting tubes drive the lifting plates to descend on their respective supporting frames. With the help of this instantaneous descending action, the top pressure plate moves downward at the same time to squeeze the air storage bag and the liquid storage bag. At this time, the disinfecting alcohol in the liquid storage bag is squeezed under the action of pressure and transported to the interior of the hollow cylinder through the L-shaped connecting tube, the hose, the inverted L-shaped connecting tube, the rotating joint and the input tube. At the same time, the air inside the air storage bag is squeezed and transported to the interior of the hollow cylinder through the L-shaped connecting tube, the hose, the inverted L-shaped connecting tube, the rotating joint and the input tube, thereby extending the corrugated telescopic air bag to the right and pushing the movable inner cylinder to move right on the outside of the sealing cylinder through the two sliders, so that the multiple tapered holes and the multiple straight holes are staggered. The inner cylinder is opened, so that the disinfecting alcohol is sealed inside the movable inner cylinder at the moment it enters the hollow cylinder. Such sealing can enable the disinfecting alcohol entering from the input tube at the right end of the hollow cylinder to flow evenly and be distributed in the hollow cylinder. When the movable inner cylinder is reset to the left under the reverse action of multiple springs, the multiple tapered holes and the multiple straight holes are instantly caused to overlap with each other, thereby effectively ensuring that the disinfecting alcohol is evenly flowed and evenly absorbed by the absorbent cotton while the hollow cylinder rotates, thereby effectively avoiding the problem of uneven absorption of the absorbent cotton and resulting in poor cleaning and sterilization effects. In addition, the provision of multiple tapered holes and multiple straight holes enables the disinfecting alcohol to decelerate and slowly penetrate outward after entering the hollow cylinder, further enabling the absorbent cotton to evenly absorb the disinfecting alcohol, greatly improving the effect of subsequent cleaning of the conveyor belt.

In summary, the prior art is uniform and will not be described in detail here.

[0039] like Figures 2 to 9 As shown, the cleaning and sterilizing assembly 2 includes two symmetrically distributed support frames 21 fixedly connected to one end of the conveyor line body 1 and away from the infrared sensor 12 and the controller 11. The two support frames 21 are fixedly connected to the same bottom support plate 22 on the opposite side walls. The bottom end of the bottom support plate 22 is flush with the bottom end of the support frame 21. The top left side of the bottom support plate 22 is fixedly connected to an air storage bag 23 with an I-shaped structure in vertical section. The right side of the air storage bag 23 is also provided with a fixed The liquid storage bag 24 at the top of the bottom support plate 22 has the same shape as the air storage bag 23. The air storage bag 23 and the liquid storage bag 24 are both fixedly connected with a plurality of equidistantly arranged I-shaped spring pieces 231. A weakened portion 232 is provided in the middle of both side walls of each I-shaped spring piece 231.

A sealing cap is also threadedly connected to the top of the liquid injection tube 26. The liquid injection tube 26 is used to add medical disinfection and sterilization alcohol to the inside of the liquid storage capsule 24. The top of the air storage capsule 23 and the liquid storage capsule 24 are fixedly connected to the same top pressing plate 27. Both ends of the top pressing plate 27 are fixedly connected to a lifting plate 28 with an I-shaped cross-section. The two support frames 21 are provided with lifting channels that are adapted to the shape of the lifting plates 28. The two lifting plates 28 are connected to the top of the air storage capsule 23 and the liquid storage capsule 24. 8 is rotatably connected to an input pipe 29 at a position near the top thereof, and the opposite ends of the two input pipes 29 are fixedly connected to the rotating end of the rotary joint 210, and the opposite ends of the two rotary joints 210 are fixedly connected to a hose 212 through an inverted L-shaped connecting pipe 211, and the two inverted L-shaped connecting pipes 211 are fixedly connected to the outer wall of the lifting plate 28 through a fixing block, and the bottom ends of the two hoses 212 are respectively extended through the L-shaped connecting pipe to be connected to the inside of the air storage bag 23 and the liquid storage bag 24.

[0040] Among them, the setting of the I-shaped spring piece 231 can enable the liquid storage bag 24 and the air storage bag 23 to actively recover after being squeezed. In addition, it can also enable the absorbent cotton 215 to continuously and tightly fit on the surface of the conveyor belt 14; and the setting of the weakened part 232 makes it easier to deform through the setting of the weakened part 232 after being squeezed.

[0041] like Figures 2 to 9 As shown, the outer sides of the opposite ends of the two input pipes 29 are fixedly connected with a same hollow cylinder 214, and the inner wall of the end of the hollow cylinder 214 close to the right input pipe 29 is fixedly connected with a sealing cylinder 2145, and the outer sliding sleeve of the sealing cylinder 2145 is provided with a movable inner cylinder 2141, and the left and right ends of the movable inner cylinder 2141 are closed and open respectively, and a groove 2142 is provided at the center of the outer side of the left end of the movable inner cylinder 2141, and a corrugated telescopic airbag 2143 is fixedly connected in the groove 2142, and the end of the corrugated telescopic airbag 2143 away from the groove 2142 is fixedly connected to the inner wall of the left end of the hollow cylinder 214, and the end of the left input pipe 29 away from the left rotary joint 210 is fixedly connected to the corrugated telescopic airbag 2143. 43, one end of the right input pipe 29 away from the right rotary joint 210 extends to the interior of the movable inner cylinder 2141, and two symmetrically distributed slide grooves are opened on the outer side of the sealing cylinder 2145, and sliders 2146 are fixedly connected in the two slide grooves. The ends of the two sliders 2146 that are away from each other are fixedly connected to the inner wall of the movable inner cylinder 2141. The periphery of the sealing cylinder 2145 is also provided with a plurality of springs 2147 arranged in a circular array, and the left ends of the plurality of springs 2147 are fixedly connected to the right end of the movable inner cylinder 2141, and a plurality of conical holes 2148 are opened on the outer side of the movable inner cylinder 2141, and a plurality of straight holes 2149 are opened on the outer side of the hollow cylinder 214, and absorbent cotton 215 is fixedly connected to the outer side of the hollow cylinder 214.

[0042] Among them, the sealing cylinder 2145 and the movable inner cylinder 2141 can both be made of hard rubber material, so that the movable connection between the sealing cylinder 2145 and the movable inner cylinder 2141 can be sealed, avoiding the accumulation of disinfectant alcohol in the area where the spring 2147 is located. In addition, the setting of the slider 2146 enables the movable inner cylinder 2141 to only move left and right without the problem of the hollow cylinder 214 rotating therewith; the setting of multiple conical holes 2148 allows the disinfectant alcohol entering the hollow cylinder 214 and the movable inner cylinder 2141 to decelerate and slowly penetrate into the external absorbent cotton 215, avoiding rapid outward penetration of disinfection and sterilization, and further enabling the absorbent cotton 215 to evenly absorb the disinfectant alcohol.

[0043] The workflow of the technical solution of the present invention is as follows:

[0044] The operator installs the cleaning and sterilizing component 2 on the outer wall of the conveyor line body 1, and drives the conveyor belt 14 through the driving device 13 to drive the placed sterile articles to convey. However, each interval protrusion 15 will intermittently squeeze the absorbent cotton 215 during the operation of the conveyor belt 14, prompting the absorbent cotton 215 to drive the hollow cylinder 214 to move downward, and the two inverted L-shaped connecting pipes 211 both drive the lifting plate 28 to descend on their respective supporting frames 21. With the help of this instantaneous descending action, the top pressure plate 27 moves downward at the same time to squeeze the air storage bag 23 and the liquid storage bag 24. At this time, the disinfecting alcohol in the liquid storage bag 24 is transported through the L-shaped connecting pipe, the hose 212, the inverted L-shaped connecting pipe 211, the rotary joint 210 and the input pipe 29 under the action of pressure. The air in the air storage bag 23 is squeezed and delivered to the interior of the hollow cylinder 214. At the same time, the air in the air storage bag 23 is squeezed and extends vertically to the bellows telescopic air bag 2143 through the L-shaped connecting pipe, the hose 212, the inverted L-shaped connecting pipe 211, the rotary joint 210 and the input pipe 29, which causes the bellows telescopic air bag 2143 to extend to the right and push the movable inner cylinder 2141 to move right on the outside of the sealing cylinder 2145 through two sliders 2146, causing the multiple conical holes 2148 and the multiple straight holes 2149 to be staggered, so that the disinfecting alcohol is enclosed in the movable inner cylinder 2141 at the moment of entering the interior of the hollow cylinder 214. Such a closure can cause the disinfecting alcohol entering from the input pipe 29 at the right end of the hollow cylinder 214 to flow evenly and be distributed in the hollow cylinder 214.

[0045] When the spacing protrusion 15 does not squeeze the absorbent cotton 215, the top pressure plate 27 is prompted to move up under the restoration setting of the multiple I-shaped spring pieces 231. At this time, the movable inner cylinder 2141 is reset to the left under the reverse action of the multiple springs 2147, instantly prompting the multiple conical holes 2148 and the multiple straight holes 2149 to overlap with each other, thereby effectively ensuring that the disinfecting and sterilizing alcohol enters the movable inner cylinder 2141 and flows evenly and is evenly absorbed by the absorbent cotton 215 while the hollow cylinder 214 rotates, thereby effectively avoiding the problem of uneven adsorption of the absorbent cotton 215 and resulting in poor cleaning and sterilization effects. In addition, the setting of the multiple conical holes 2148 and the multiple straight holes 2149 prompts the disinfecting and sterilizing alcohol to decelerate and slowly penetrate outward after entering the hollow cylinder 214, further prompting the absorbent cotton 215 to evenly absorb the disinfecting and sterilizing alcohol, greatly improving the sterilization effect of the subsequent cleaning conveyor belt 14.

[0046] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention, but those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0047] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
