Description

Technical Field

[0001] This invention belongs to the field of paper disinfection technology, and in particular relates to a gas disinfection device for preventing the spread of pathogenic microorganisms. Background Technology

[0002] The management of paper-based experimental records and documents in biosafety laboratories is crucial. When internal laboratory documents are transferred externally, they must comply with the requirements of the "Laboratory Biosafety Accreditation Criteria," requiring thorough disinfection of paper documents to render any potential contaminants and microorganisms harmless, while simultaneously ensuring the integrity of the relevant records and documents. Current technology typically uses ultraviolet (UV) disinfection via pass-through windows to sterilize paper. However, this method has several drawbacks. Placing paper in layers into the UV disinfection device means that UV light can only penetrate the surface layer, failing to reach deeper layers and thus failing to effectively kill deeper microorganisms, resulting in incomplete disinfection. Some UV disinfection devices send paper to the device one by one for sterilization, but this process is time-consuming and labor-intensive. Summary of the Invention

[0003] (a) Technical problems to be solved

[0004] This invention provides a gas sterilization device for preventing the spread of pathogenic microorganisms to address the following problem:

[0005] 1. Existing ultraviolet disinfection equipment cannot thoroughly disinfect stacked paper.

[0006] 2. Send the paper sheets one by one to the ultraviolet disinfection equipment for disinfection, which will take a lot of time.

[0007] (II) Technical Content

[0008] To achieve the above objectives, the present invention provides the following technical solution:

[0009] A gas disinfection device for preventing the spread of pathogenic microorganisms includes a disinfection chamber, with a paper inlet and a paper outlet at the top of the chamber, and guide rails on both sides of the inner wall of the chamber.

[0010] It also includes a deflecting paper clamp, which includes two side clamping assemblies and a rotary motor disposed between two guide rails. The output shaft of the rotary motor is fixedly connected to a shaped docking plate. The two side clamping assemblies are mounted vertically on one side of the shaped docking plate. The end of the shaped docking plate is fixedly connected to a side support plate. The side support plate is pressed against the two side clamping assemblies. The shaped docking plate is also provided with a push-off structure for separating the lower side clamping assembly from the side support plate.

[0011] An air jet pipe is fixed to the bottom of the inner wall of the disinfection chamber, and an exhaust port is provided at the top of the air jet pipe;

[0012] It also includes an opening assembly, which is fixed to the paper inlet. When the deflecting paper clamp moves to the paper inlet, the opening assembly is used to separate the upper side clamp assembly from the side support plate to facilitate paper feeding.

[0013] A control terminal is installed on one side of the sterilization chamber.

[0014] Furthermore, two guide rails are symmetrically fixed to the inner wall of the disinfection chamber, and a suspension arm is slidably connected to each of the two guide rails. The same rotary motor is fixed to the end of the two suspension arms that are close to each other.

[0015] Both guide rails are equipped with lead screws, the two ends of which are rotatably connected to the inner wall of the sterilization chamber. The two lead screws have the same thread path and mesh with the suspension arm on the same side.

[0019] A rubber pad is attached to one side of the bottom of the clamping plate, and a rubber pad is also attached to the side of the side support plate near the clamping plate. When the transmission pull plate comes into contact with the irregularly shaped docking plate, the two rubber pads at the same height are squeezed together.

[0020] Furthermore, the push-away structure includes an air supply pump fixedly connected to the irregularly shaped docking plate and two single-acting cylinders. The positions of the two single-acting cylinders correspond to the two transmission pull plates respectively.

[0023] The rotary motor, air pump, and two single-acting cylinders are all connected to the control terminal via signal transmission.

[0024] Furthermore, multiple sets of jet pipes are provided and located directly below the directional paper clamp. The air inlet end of the jet pipe extends out into the sterilization chamber and is connected to an external air supply unit. A flow equalization plate is inserted inside the sterilization chamber and is located above the jet pipe.

[0025] The disinfection chamber is equipped with an air inlet and an exhaust outlet on both sides. The air inlet and exhaust outlets are connected to an external air exchange and circulation device, which is connected to the control terminal via signal transmission.

[0026] Furthermore, the opening assembly includes an integrated cover and a stop bar. The integrated cover is fixed to the sterilization chamber, and a straight groove is provided on the integrated cover to communicate with the paper inlet.

[0027] The disinfection chamber is slidably connected to an L-shaped bottom support plate on the side near the straight groove opening. The integrated cover is symmetrically provided with an installation chamber. The straight groove opening is symmetrically provided with a stepped slide groove. A second spring is placed at the bottom of the stepped slide groove. A slider is symmetrically fixed to the stop bar. The slider is slidably connected to the stepped slide groove on the same side, and its bottom is in contact with the second spring.

[0028] The installation chamber is equipped with an outer push slide rail and an inner push slide rail. The inner push slide rail is located below the outer push slide rail.

[0032] Furthermore, the disinfection chamber is divided into five stages in sequence: paper feeding zone, disinfection zone, flipping zone, disinfection zone, and termination zone. The paper feeding port and opening assembly are located in the paper feeding zone, and the paper output port is located in the termination zone. The directional paper clamp will pass through the paper feeding zone, disinfection zone, flipping zone, disinfection zone, and termination zone in sequence. The exhaust port at the top of the jet pipe is located in the two disinfection zones.

[0033] Among them, at least one flipping zone shall be set, and at least two disinfection zones shall be set, which shall be distributed alternately with the flipping zone;

[0034] A viewing window is provided on one side of the sterilization chamber.

[0035] Furthermore, the top of both the integrated cover and the paper outlet is hinged with a locking cover, and the top of both the integrated cover and the sterilization chamber is rotatably connected with a lock head, which abuts against the locking cover on the same side.

[0036] (III) Beneficial Effects

[0037] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0038] I. In this invention, a directional paper clamp can hold the paper, and a jet pipe located below the directional paper clamp can spray disinfecting gas from the bottom of the paper, allowing the disinfecting gas to gradually spread upwards from the bottom of the paper, thereby disinfecting the paper. When the directional paper clamp passes through the flipping zone, the directional paper clamp can rotate the paper 180°. During the flipping process, the single-acting cylinder, which was originally located at the top, moves to the bottom and changes from a stopped state to an active state. At this time, the air supply pump delivers gas to the single-acting cylinder through an electric valve. The telescopic end of the single-acting cylinder extends and gradually approaches the transmission pull plate. When the telescopic end of the single-acting cylinder contacts the transmission pull plate, the transmission pull plate also moves together, thereby driving the clamping plate to move together through the limit slide rod. At this time, the clamping plate and side support plate located at the bottom stop clamping the paper, so that the subsequent disinfecting gas can be blown onto the paper, thereby fully disinfecting the paper and preventing the area of ​​the paper clamped by the clamping plate and side support plate from not being disinfected.

[0039] Second, in this invention, at least one flipping zone is set, and at least two disinfection zones are set and distributed alternately with the flipping zone. Staff can set additional flipping zones and disinfection zones according to actual needs, so as to flip and disinfect the paper multiple times and thoroughly disinfect the paper.

[0040] Third, in this invention, the air inlet and exhaust ports are connected to an external air exchange and circulation device. During operation, the external air exchange and circulation device ensures that the air pressure inside the disinfection chamber remains constant. When the deflecting paper clamp passes through the termination zone, the air exchange and circulation device discharges outside air into the disinfection chamber through the air inlet port and discharges the disinfectant gas in the disinfection chamber to the designated recycling area through the exhaust port for gas exchange. This prevents the disinfectant gas from being inhaled by the staff after they open the locking cover at the paper outlet.

[0041] Fourth, in this invention, the two sides of the stacked paper are clamped and limited by the side support plate and the clamping plate. The rubber pad can increase the friction between the paper and the rubber pad, so as to prevent the paper from falling off during the sterilization process.

[0042] Fifth, in this invention, the distance between the irregularly shaped mating plate and the side support plate can be increased while fixing the side support plate, so as to facilitate the installation of the side clamping assembly. Attached Figure Description

[0057] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0058] Example 1

[0059] like Figures 1-13As shown, a gas disinfection device for preventing the spread of pathogenic microorganisms includes a disinfection chamber 11. The top of the disinfection chamber 11 is provided with a paper inlet and a paper outlet. During installation, the disinfection chamber 11 is fixed to the wall of the laboratory. The paper inlet is located inside the wall of the laboratory, and the paper outlet is located outside the wall of the laboratory. A control terminal is provided on one side of the disinfection chamber 11, and guide rails 12 are provided on both sides of the inner wall of the disinfection chamber 11.

[0060] The gas sterilization device for preventing the spread of pathogenic microorganisms also includes a deflecting paper clamp, which comprises two side clamping assemblies and a rotary motor 31 disposed between two guide rails 12, specifically as follows: Figure 3 As shown, two guide rails 12 are symmetrically fixed to the inner wall of the disinfection chamber 11. Each guide rail 12 is slidably connected to a suspension arm 13, and the same rotary motor 31 is fixed to one end of the two suspension arms 13 that are close to each other.

[0061] Both guide rails 12 are equipped with lead screws 14. The two ends of the lead screws 14 are rotatably connected to the inner wall of the disinfection chamber 11, and the thread paths of the two lead screws 14 are the same. The lead screws 14 are engaged with the suspension arms 13 on the same side. The same end of the two lead screws 14 extends out of the disinfection chamber 11, and a belt reel 141 is fixedly sleeved on the extended lead screw 14. The same transmission belt 142 is engaged on the two belt reels 141. A first drive motor 15 is fixedly connected to one side of the disinfection chamber 11, and the output shaft of the first drive motor 15 is fixedly connected to one of the lead screws 14.

[0062] Specifically: When the drive motor 31 moves, the output shaft of the first drive motor 15 drives one of the lead screws 14 to rotate. Under the action of the transmission belt 142, the other lead screw 14 rotates synchronously. Under the meshing action, the drive motor 31 moves along the guide rail 12 through the suspension arm 13.

[0063] Among them, staff can install a protective cover on one side of the sterilization chamber 11 to cover the first drive motor 15, the pulley 141 and the transmission belt 142, so as to prevent debris from falling onto the pulley 141.

[0064] like Figures 3-5 As shown, the output shaft of the rotary motor 31 is fixedly connected to the irregularly shaped docking plate 32. Two side clamping assemblies are installed vertically on one side of the irregularly shaped docking plate 32. The side support plate 33 is pressed against the two side clamping assemblies. Specifically, the side clamping assembly includes a clamping plate 41 with a Z-shaped side. Multiple limiting slide rods 42 are symmetrically inserted into one side of the irregularly shaped docking plate 32. The same end of the multiple limiting slide rods 42 extends out of the irregularly shaped docking plate 32 and is threaded into the bottom side of the clamping plate 41. The other end is fixedly connected to the same transmission pull plate 43.

[0065] A first spring 421 is sleeved on the limiting slide rod 42. The first spring 421 is located between the clamping plate 41 and the irregular docking plate 32. The first spring 421 is in a compressed state and its two ends abut against the clamping plate 41 and the irregular docking plate 32 respectively.

[0066] During installation, first insert the limiting slide rods 42 one by one onto the irregular docking plate 32, then put the first spring 421 on the limiting slide rod 42, and then thread one end of the limiting slide rod 42 onto the clamping plate 41, thereby suspending the clamping plate 41. Then, fix the other end of the limiting slide rod 42 to the transmission pull plate 43 with screws.

[0067] The irregularly shaped butt plate 32 is fixedly connected to the end of a side support plate 33. The side support plate 33 and the clamping plate 41 clamp and limit the two sides of the stacked paper to prevent it from falling during the operation. Specifically, the irregularly shaped butt plate 32 has integrally formed extension legs 321 on both sides. The side support plate 33 is fixedly connected to the free end of the extension legs 321. The extension legs 321 can increase the distance between the irregularly shaped butt plate 32 and the side support plate 33 while fixing the side support plate 33, so as to facilitate the installation of the side clamping assembly.

[0068] Specifically, after installation, the first spring 421, which is in a compressed state, will continuously push the clamping plate 41 to move along the side near the side support plate 33. When the transmission pull plate 43 contacts the irregular docking plate 32, the clamping plate 41 moves to its maximum extent. At the same time, a rubber pad 411 is attached to the bottom side of the clamping plate 41, and a rubber pad 411 is also attached to the side of the side support plate 33 near the clamping plate 41. When the transmission pull plate 43 contacts the irregular docking plate 32, the two rubber pads 411 at the same height are pressed together (this is the initial state). The rubber pads 411 can increase the friction between the paper and the paper, preventing the paper from falling off during the sterilization process.

[0069] The irregularly shaped docking plate 32 is also provided with a push-away structure for separating the side clamp assembly located below from the side support plate 33, specifically as follows: Figure 3 As shown, the push-away structure includes an air supply pump 34 fixedly connected to the irregular docking plate 32 and two single-acting cylinders 35. The positions of the two single-acting cylinders 35 correspond to the two transmission pull plates 43 respectively. The irregular docking plate 32 is provided with a clearance opening 3201 corresponding to the single-acting cylinder 35. The telescopic end of the single-acting cylinder 35 is located in the corresponding clearance opening 3201.

[0070] The air supply pump 34 has two air supply ends, and the two air supply ends are respectively connected to the air inlet ends of two single-acting cylinders 35 through electric valves;

[0071] Specifically, the air pump 34 delivers gas to the single-acting cylinder 35 via an electric valve. At this time, the telescopic end of the single-acting cylinder 35 extends and gradually approaches the transmission pull plate 43. When the telescopic end of the single-acting cylinder 35 contacts the transmission pull plate 43, the transmission pull plate 43 also moves together, thereby driving the clamping plate 41 to move together via the limit slide rod 42. At this time, the clamping plate 41 separates from the side support plate 33, thereby providing a space for placing paper between the clamping plate 41 and the side support plate 33. At the same time, the first spring 421, which is in a compressed state, will be further compressed.

[0072] Among them, the two single-acting cylinders 35 are in a non-working state, while the single-acting cylinder 35 located at the bottom is in a working state, so as to prevent the bottom of the paper from being clamped and affecting the sterilizing gas from being blown onto the paper.

[0073] Among them, the push-away structure and the first spring 421 are located on the side of the irregular docking plate 32 away from the transmission pull plate 43;

[0074] The rotary motor 31, the air pump 34, and the two single-acting cylinders 35 are all connected to the control terminal via signal transmission, so that the commissioning personnel can make unified adjustments through the control terminal.

[0075] like Figure 1 and Figure 3 As shown, a jet pipe 21 is fixedly connected to the bottom of the inner wall of the disinfection chamber 11. Specifically, multiple sets of jet pipes 21 are provided and located directly below the directional paper clamp. The top of the jet pipe 21 is provided with an exhaust hole for spraying disinfecting gas. The air inlet of the jet pipe 21 extends out of the disinfection chamber 11 and is connected to an external air supply unit. The disinfecting gas is used to disinfect the paper. The staff can adjust the air supply volume through the air supply unit. A flow equalization plate 16 is inserted inside the disinfection chamber 11. The flow equalization plate 16 is located above the jet pipe 21. The flow equalization plate 16 can evenly discharge the disinfecting gas and also protect the jet pipe 21 below it, preventing debris from falling on the jet pipe 21 and blocking the exhaust hole during installation and maintenance.

[0076] The gas sterilization device for preventing the spread of pathogenic microorganisms also includes an opening assembly, which is fixedly connected to the paper inlet, specifically as follows: Figure 2 , Figures 6-10 As shown, the opening assembly includes an integrated cover 51 and a stop bar 52. The integrated cover 51 is fixed to the sterilization chamber 11 by screws so that it can be disassembled during later maintenance. The integrated cover 51 has a straight groove 5101 that communicates with the paper inlet.

[0077] The disinfection chamber 11 is slidably connected to an L-shaped bottom support plate 17 on one side near the straight groove 5101. The integrated cover 51 is symmetrically provided with an installation chamber 5102. The straight groove 5101 is symmetrically provided with a stepped slide 5103. A second spring 18 is placed at the bottom of the stepped slide 5103. A slider 521 is symmetrically fixed on the stop bar 52. The slider 521 is slidably connected to the stepped slide 5103 on the same side, and its bottom is in contact with the second spring 18.

[0078] The mounting chamber 5102 is provided with an outer push slide rail 5104 and an inner push slide rail 5105. The inner push slide rail 5105 is located below the outer push slide rail 5104. An inner push tooth plate 53 is slidably connected in the inner push slide rail 5105, and an outer push tooth plate 54 is slidably connected in the outer push slide rail 5104. A reversing gear 55 is rotatably connected in the mounting chamber 5102. The reversing gear 55 meshes with the inner push tooth plate 53 and the outer push tooth plate 54 respectively.

[0079] One end of the outward push plate 54 is provided with an inclined part 541. Both ends of the stop rod 52 extend into the mounting chamber 5102 on the same side, and the ends are rotatably connected to rollers 523 through connecting ears 522. The rollers 523 roll in contact with the inclined part 541 on the same side. A plurality of top heads 524 are fixedly connected to one side of the stop rod 52. In the initial state, the bottom of the top head 524 is located above the clamping plate 41.

[0080] Furthermore, a limiting block 56 is fixedly connected in the installation chamber 5102, a step rod 57 is slidably connected on the limiting block 56, a third spring 58 is sleeved on the step rod 57, one end of the step rod 57 is threadedly fixed to the inner push tooth plate 53 located at the same height, and both ends of the third spring 58 abut against the limiting block 56 and the inner push tooth plate 53 respectively.

[0081] Specifically, when the bottom support plate 17 slides away from the rotary motor 31, it will press the inner push tooth plate 53, causing it to slide along the inner push slide rail 5105. At this time, the third spring 58 located between the inner push tooth plate 53 and the limit block 56 will be compressed. At the same time, the reversing gear 55 will rotate clockwise and drive the outer push tooth plate 54 to slide on the outer push slide rail 5104 in the direction close to the rotary motor 31. During the sliding process, the inclined part 541 will press the connecting ear 522 downward through the roller 523, so that the stop bar 52 and the slider 521 will slide downward along the stepped slide groove 5103. At this time, the second spring 18 will be compressed, and the top head 524 will also move downward to facilitate the subsequent limiting of the clamping plate 41.

[0082] Pre-push rods 331 are fixed to the four corners of the side support plate 33 near the bottom support plate 17. When the side support plate 33 passes the top head 524, the pre-push rods 331 contact the bottom support plate 17 and push the bottom support plate 17 in advance through the pre-push rods 331, so that it slides away from the rotating motor 31, thereby allowing the top head 524 to move down in advance, in preparation for limiting the clamping plate 41.

[0083] Furthermore, such as Figure 11 As shown, the disinfection chamber 11 is divided into five stages in sequence: paper feeding section 113, disinfection section 114, flipping section 115, disinfection section 116 and termination section 116. The paper feeding port and the opening assembly are located at the paper feeding section 113 and the paper output port is located at the termination section 116.

[0084] The deflecting paper clamp will pass through the paper feeding section 113, the disinfection section 114, the flipping section 115, the disinfection section 114 and the termination section 116 in sequence.

[0085] When the directional paper clamp passes through the paper feeding section 113, it places the paper to be disinfected onto the directional paper clamp in cooperation with the opening assembly. When the directional paper clamp passes through the first disinfection section 114, the jet pipe 21 sprays disinfecting gas through the exhaust port to disinfect the paper. When the directional paper clamp passes through the flipping section 115, the paper is rotated 180 degrees under the action of the directional paper clamp. During the rotation, the side clamping assembly and side support plate 33, which were originally located below and in a separated state, are merged under the action of the pushing structure, thereby clamping the paper. The side clamping assembly and side support plate 33, which were originally located above and clamping the paper, are separated, thereby canceling the clamping of the paper. When the directional paper clamp passes through the second disinfection section 114, the jet pipe 21 repeats the first working process (the specific working process has been described above and will not be repeated here) to disinfect the rotated paper. When the directional paper clamp passes through the termination section 116, the work is completed and the paper can be taken out.

[0086] The system includes at least one flipping zone 115 and at least two disinfection zones 114, which are alternately distributed with the flipping zone 115. Staff can set additional flipping zones 115 and disinfection zones 114 as needed to perform multiple flipping and disinfection processes on the paper, ensuring thorough disinfection. During debugging, when the rotary motor 31 moves to the disinfection zone 114, the debugging personnel can slow down the speed of the first drive motor 15, thereby reducing the moving speed of the rotary motor 31 and extending the disinfection time for the paper, ensuring thorough disinfection.

[0087] Furthermore, the top of the integrated cover 51 and the paper outlet are both hinged with locking covers 59, and the top of the integrated cover 51 and the sterilization chamber 11 are both rotatably connected with locking heads 510. The locking heads 510 abut against the locking covers 59 on the same side, thereby sealing the paper inlet and the paper outlet. When putting or taking out paper, rotate the corresponding locking head 510 to stop it from abutting against the locking cover 59, and then rotate the locking cover 59 to open it.

[0088] In summary, the specific workflow of this invention is as follows:

[0089] S1: Before adding paper, open the locking cover 59 located at the integrated cover head 51 and adjust the device to the initial state, that is, drive one of the lead screws 14 to rotate through the output shaft of the first drive motor 15. Under the action of the transmission belt 142, the other lead screw 14 rotates synchronously. Under the meshing action, the rotating motor 31 is driven to move along the direction close to the bottom support plate 17 through the suspension arm 13. The operator can control the speed of the first drive motor 15 through the control terminal, thereby adjusting the moving speed of the rotating motor 31.

[0090] During the movement, after the side support plate 33 passes the top head 524, the bottom of the side support plate 33 is above the horizontal section of the L-shaped bottom support plate 17. At the same time, the pre-push rod 331 contacts the bottom support plate 17. As the rotary motor 31 continues to move, the side support plate 33 pushes the bottom support plate 17 through the pre-push rod 331, causing it to slide in a direction away from the rotary motor 31. During the sliding, the bottom support plate 17 presses against the inner push tooth plate 53, causing it to slide along the inner push slide rail 5105. The third spring 58 located between the inner push tooth plate 53 and the limit block 56 is compressed. At the same time, the reversing gear 55 rotates clockwise and, under the meshing action, drives the outer push tooth plate 54 to slide on the outer push slide rail 5104 in a direction closer to the rotary motor 31. At this time, the third spring 58 located between the outer push tooth plate 54 and the limit block 56 is compressed. During the sliding process, the inclined part 541 passes through the roller 52 3. Press down on the connecting ear 522, so that the stop bar 52 and the slider 521 slide down along the stepped slide groove 5103. At this time, the second spring 18 is compressed, and the top head 524 also moves down. At this time, the bottom of the top head 524 will be lower than the top of the clamping plate 41. As the rotary motor 31 continues to move, the top head 524 contacts the top side of the clamping plate 41. At this time, the top head 524 will prevent the clamping plate 41 from moving. As the rotary motor 31 drives the irregular docking plate 32 to continue to move, the clamping plate 41 and the side support plate 33 that are being pressed apart separate. As the irregular docking plate 32 moves, the distance between the clamping plate 41 and the side support plate 33 gradually increases. At the same time, the staff can stack the paper that needs to be disinfected and insert it between the clamping plate 41 and the side support plate 33 and wait for the clamping plate 41 and the side support plate 33 to clamp it. At this time, the bottom of the paper contacts the horizontal end of the L-shaped bottom support plate 17.

[0091] When placing the paper, the staff needs to hold the top of the paper with their hand and place it between the clamping plate 41 and the side support plate 33 without letting go. When the bottom support plate 17 is pushed to contact the inner wall of the sterilization chamber 11, the rotary motor 31 and the top head 524 move to their maximum extent. At the same time, the distance between the clamping plate 41 and the side support plate 33 also expands to its maximum extent. At this time, the output shaft of the rotary motor 31 rotates in the opposite direction, thereby driving the irregularly shaped docking plate 32 and the side support plate 33 to move in the opposite direction. At this time, the side support plate 33 will gradually approach the clamping plate 41. When both the side support plate 33 and the clamping plate 41 are in contact with the paper, the paper is clamped between the side support plate 33 and the clamping plate 41 under the action of the first spring 421. At this time, the staff can let go and close the locking cover 59 located at the integrated cover head 51.

[0092] During the debugging process, when the rotary motor 31 moves to the paper feeding section 113, the debugging personnel can slow down the speed of the first drive motor 15, thereby slowing down the moving speed of the rotary motor 31, so that the staff has enough time to place the paper.

[0093] At the same time, when the side support plate 33 is reversed and reset, the pre-push rod 331 stops pushing the bottom support plate 17. At this time, the third spring 58, which is in a compressed state, will stretch and reset, thereby pushing the inner push tooth plate 53 to reset. Under the meshing action, the outer push tooth plate 54 will also reset synchronously. During the reset process of the inclined part 541, the downward squeezing force applied to the roller 523 disappears. At this time, the second spring 18, which is in a compressed state, will stretch and reset, thereby pushing the slider 521 and the stop rod 52 upward, so that the top head 524 will also reset synchronously.

[0094] During preparation, ball bearings can be slidably embedded on the side of the top head 524 near the clamping plate 41 to reduce friction with the clamping plate 41.

[0095] S2: As the rotary motor 31 moves, when the deflecting paper clamp passes through the first disinfection zone 114, the external air supply machine starts to supply air, and the jet pipe 21 sprays disinfectant gas from the bottom of the paper through the exhaust hole, so that the disinfectant gas gradually spreads upward from the bottom of the paper to disinfect the paper.

[0096] S3: As the rotary motor 31 moves, when the deflecting paper clamp passes through the flipping zone 115, the external air supply stops supplying air. At the same time, the rotary motor 31 drives the irregular docking plate 32 to rotate 180° through the output shaft. Before the rotation, the single-acting cylinder 35 located below stops working. At this time, the first spring 421, which is in a compressed state, will continue to push the clamping plate 41 to move along the side close to the side support plate 33, thereby clamping the lower half of the paper and preventing the layers of paper from spreading to both sides during rotation.

[0097] After rotation, the single-acting cylinder 35, which was originally located at the top, moves to the bottom and changes from a stopped state to an active state. At this time, the air supply pump 34 delivers gas to the single-acting cylinder 35 through an electric valve. The telescopic end of the single-acting cylinder 35 extends and gradually approaches the transmission pull plate 43. When the telescopic end of the single-acting cylinder 35 contacts the transmission pull plate 43, the transmission pull plate 43 also moves, thereby driving the clamping plate 41 to move together through the limit slide rod 42. At this time, the clamping plate 41 and the side support plate 33 located at the bottom stop clamping the paper, so that the disinfecting gas can be blown onto the paper later.

[0098] S4: As the rotary motor 31 moves, when the deflecting paper clamp passes through the second disinfection zone 114, the external air supply machine starts to supply air, and the jet pipe 21 once again sprays disinfectant gas from the bottom of the paper through the exhaust hole, so that the disinfectant gas gradually spreads upward from the bottom of the paper to disinfect the paper.

[0099] In particular, steps S2 and S4 can effectively disinfect the paper, ensuring that the area where the paper is held by the clamping plate 41 and the side support plate 33 is not disinfected.

[0100] S5: During the paper disinfection process, after completing their own disinfection procedures, the staff waits outside the laboratory. As the rotary motor 31 moves, when the deflecting paper clamp passes through the termination zone 116, the external air supply stops supplying air, and the rotary motor 31 stops working. The staff opens the locking cover 59 located at the paper outlet, then pinches the top of the paper with one hand and pulls the clamp 41 outward with the other hand to stop clamping the paper, and then removes the paper.

[0101] Among them, such as Figure 1 and Figure 2 As shown, the disinfection chamber 11 is provided with an air inlet 111 and an exhaust 112 on both sides. The air inlet 111 and the exhaust 112 are connected to an external air exchange and circulation device. During operation, the external air exchange and circulation device can ensure that the air pressure inside the disinfection chamber 11 is constant. When the deflecting paper clamp passes through the termination section 116, the outside air is discharged into the disinfection chamber 11 through the air inlet 111 under the action of the air exchange and circulation device. The disinfection gas in the disinfection chamber 11 is discharged to the designated recycling area through the exhaust 112 for gas exchange. This prevents the disinfection gas from being discharged through the paper outlet and inhaled by the staff after the staff opens the locking cover 59 located at the paper outlet.

[0102] Furthermore, such as Figure 11 As shown, a viewing window 19 is provided on one side of the disinfection chamber 11, through which staff can observe the working conditions inside the disinfection chamber 11.

[0103] Example 2

[0104] like Figures 1-13 As shown, this embodiment has been improved based on Embodiment 1 as follows: Furthermore, to improve adaptability, as... Figure 12 and Figure 13 As shown, a sterilizing cabinet 61 for sterilizing containers can be fixed to one side of the sterilizing chamber 11. Two rotating shafts 62 are installed and rotatably connected inside the sterilizing cabinet 61, and the same transmission belt 63 is fitted on the two rotating shafts 62. Bottle inlets and bottle outlets are respectively provided on both sides of the sterilizing cabinet 61. The sterilizing cabinet 61 and the sterilizing chamber 11 are fixed together to the wall of the laboratory, with the bottle inlet located on the inner side of the laboratory wall and the bottle outlet located on the outer side of the laboratory wall. Locking covers 59 are hinged to both sides of the sterilizing cabinet 61, and the locking covers 59 correspond to the bottle inlets and bottle outlets on the same side. Lock heads 510 are also rotatably connected to both sides of the sterilizing cabinet 61, and the lock heads 510 abut against the locking covers 59 on the same side.

[0105] Furthermore, a second drive motor 64 is fixedly connected to one side of the disinfection cabinet 61, and the output shaft of the second drive motor 64 is fixedly connected to one of the rotating shafts 62.

[0106] Furthermore, on one side of the disinfection cabinet 61, there are two sets of start / stop buttons 641 electrically connected to the second drive motor 64, and the start / stop buttons 641 correspond to the bottle inlet and bottle outlet on the same side.

[0107] Furthermore, the inner wall of the disinfection cabinet 61 is fixed with multiple branch pipes 65. The air inlet end of the multiple branch pipes 65 is connected to the exhaust port 112 set on the disinfection chamber 11 through the connecting pipe 66. The branch pipes 65 are located above the transmission belt 63, and the bottom of the branch pipes 65 is provided with an exhaust hole.

[0108] The disinfection cabinet 61 also has an exhaust port 112 on one side.

[0109] The staff rotates the lock 510 at the bottle inlet to stop it from contacting the locking cover 59, then opens the locking cover 59 and places the bottle to be sterilized on the conveyor belt 63. During the placement process, the start / stop button 641 can be pressed to control the second drive motor 64. The output shaft of the second drive motor 64 drives the rotating shaft 62 to rotate. At this time, the conveyor belt 63 will transport the bottle along the direction closer to the bottle outlet, so that the staff can place the bottle.

[0110] After placement, close the locking cover 59 and rotate the lock head 510 to make it re-abut against the locking cover 59.

[0111] During installation, the exhaust port 112 on the disinfection chamber 11 is disconnected from the external air exchange and circulation equipment and connected to the branch pipe 65 through the connecting pipe 66. Then, the exhaust port 112 on the disinfection cabinet 61 is connected to the external air exchange and circulation equipment. The disinfection gas in the disinfection chamber 11 can be transported to the branch pipe 65 through the exhaust port 112 and the connecting pipe 66 to disinfect the bottles in the disinfection cabinet 61. After the work is completed, the disinfection gas in the disinfection chamber 11 and the disinfection cabinet 61 is discharged into the air exchange and circulation equipment through the exhaust port 112 on the disinfection cabinet 61. Outside air is discharged into the disinfection chamber 11 through the air inlet 111 and then discharged into the disinfection cabinet 61 through the connecting pipe 66 and the branch pipe 65 for gas exchange.

[0112] During the bottle disinfection process, staff members complete their own disinfection procedures and wait outside the laboratory. After the bottles are disinfected, staff members rotate the lock 510 at the bottle outlet to stop it from engaging with the locking cap 59. Then, they open the locking cap 59 and take out the disinfected bottle. During the removal process, the start / stop button 641 can be pressed to control the second drive motor 64, causing the transmission belt 63 to convey the bottle along the direction close to the bottle outlet, so that staff members can take out the bottle.

[0113] Alternatively, the preparation personnel can install ultraviolet germicidal lamps on the inner walls of the disinfection chamber 11 and the disinfection cabinet 61 to assist in the disinfection of the paper.

[0114] However, as is well known to those skilled in the art, the working principles and wiring methods of the control terminal, the first drive motor 15, the rotary motor 31, the air supply pump 34, the electric valve, the single-acting cylinder 35, the air exchange and circulation equipment, the second drive motor 64, and the start / stop button 641 are commonplace and belong to conventional means or common knowledge. They will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.
