Description
Technical Field
[0001] This invention belongs to the field of medical waste disposal technology, and more specifically, relates to an automated low-temperature medical waste disposal device. Background Technology
[0002] Waste management in medical and biological institutions is a crucial aspect of public health management. Currently, waste collection largely relies on manual labor, involving the placement of various types of waste into specialized garbage bags and transporting them to centralized recycling stations. However, this model has significant shortcomings at the end of the processing flow—the internal management and temporary sorting and storage at the recycling stations.
[0003] A prominent problem is the haphazard and mixed sorting of waste. Because garbage bags look similar, bagged waste of different categories (such as infectious, sharps, and chemical waste) is easily mixed up and piled up in recycling stations. Relying on manual sorting is not only inefficient but also prone to errors, creating a risk of cross-contamination. This is especially true for pathological waste, particularly special waste such as laboratory animal carcasses, which requires even stricter handling standards. However, existing ambient temperature recycling stations often simply mix these special wastes with other garbage bags or place them in a corner. This mixed storage method can lead to hygiene and safety hazards due to decay and leakage, while also creating difficulties in identification and handover for subsequent professional collection and disposal. Summary of the Invention
[0004] This invention provides an automated low-temperature storage device for medical waste, which solves the problems of crude classification in medical waste recycling stations, lack of low-temperature storage for special medical waste, and low efficiency of manual sorting.
[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: An automated low-temperature medical waste disposal device is provided, comprising a cold storage, several recycling cages, a data entry device, and a gripping component. A circular track is provided on the top wall of the cold storage and extends through the front side wall of the cold storage. Several recycling cages are spaced apart within the cold storage along the circular track, each recycling cage having an upward opening and located below the circular track. The data entry device is located on the front side of the cold storage and is used to input information about the waste inside the garbage bags. The gripping component is slidably connected to the bottom of the circular track and is used to grip the garbage bags and dispose of them into one of the recycling cages.
[0006] In one possible implementation, a transfer member is slidably connected to the front of the cold storage in the vertical direction. The transfer member is provided with a hook extending forward for hooking the garbage bag. The transfer member can move upward to transfer the garbage bag onto the gripping component.
[0007] In some embodiments, the outer cover of the cold storage is provided with a recovery compartment, the recovery compartment has an opening facing the front, an entrance and exit are provided through the front side wall of the cold storage, and a door for sealing the entrance and exit is provided on the front side wall of the cold storage, the door and the opening are arranged opposite to each other.
[0008] In some embodiments, a delivery port located on the open side is provided through the front side wall of the recycling bin, and a sealing door for blocking the delivery port is slidably connected to the front side wall of the recycling bin in the horizontal direction. The transfer component is located inside the recycling bin and is arranged opposite to the sealing door, and the data entry device is arranged on the sealing door.
[0009] In some embodiments, the top of the sealing door is slidably connected to the recycling bin, and the bottom is provided with rollers that roll in cooperation with the recycling bin. A horizontally extending telescopic member is provided on the front side wall of the recycling bin, with one end of the telescopic member connected to the recycling bin and the other end connected to the sealing door.
[0010] In one possible implementation, the gripping component includes a gripping slide, two gears, and two swing claws. The gripping slide is slidably connected to a circular track. The two gears are rotatably connected to the gripping slide via rotating shafts and mesh with each other. The two swing claws are fixedly connected to the two rotating shafts one-to-one and are arranged opposite each other. The two swing claws can swing towards each other to hook the handles of the garbage bag or move away from each other to release the garbage bag.
[0011] In one possible implementation, a drive assembly is slidably connected to the bottom of the circular track. The drive assembly is connected to the gripping assembly via a hinge rod, with one end of the hinge rod hinged to the drive assembly and the other end hinged to the gripping assembly. The drive assembly is used to move the gripping assembly.
[0012] In some embodiments, the drive assembly includes a mating seat and a drive seat. The mating seat is slidably connected to the annular track, and the hinge rod is hinged to the mating seat. The drive seat is disposed on the mating seat, and a drive wheel that rolls with the bottom surface of the annular track is rotatably connected to the drive seat. The drive wheel is driven by a rotation drive component.
[0013] In some embodiments, the drive seat is provided with a horizontally extending reinforcing rod located below the mating seat, and the mating seat is provided with a guide rod that penetrates downward through the reinforcing rod. An elastic element located below the reinforcing rod is sleeved on the guide rod, and the lower end of the elastic element is connected to the guide rod to push the reinforcing rod upward so that the drive wheel abuts against the circular track.
[0014] In one possible implementation, the front wall of the cold storage has two passageways located near the two sides of the cold storage, a ring track runs through the two passageways, and an isolation door for sealing the passageways is slidably connected to the front wall of the cold storage in the vertical direction.
[0015] The automated low-temperature medical waste disposal device provided in this embodiment, compared with the prior art, achieves an automated process of medical waste information entry, accurate disposal, and classified storage by setting up multiple dedicated recycling cages for different categories and combining the linkage of data entry equipment and grabbing components. This completely replaces manual sorting, avoids mixing of different types of medical waste, and reduces the risk of cross-contamination.
[0016] Cold storage provides a low-temperature environment that can effectively inhibit the decay and bacterial growth of pathological medical waste (such as laboratory animal carcasses), while the classified recycling cages achieve physical separation between special medical waste and ordinary medical waste.
[0017] Automated disposal replaces manual operation, reducing labor intensity and avoiding classification errors caused by manual disposal. At the same time, medical waste information is traceable, providing clear information support for subsequent collection and disposal, and solving the problem of subsequent identification and handover difficulties.

[0021] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the invention, "a number" means two or more, unless otherwise explicitly specified.
[0023] The front of the cold storage 20 described in the entire text is Figure 1 The cold storage 20 has a door 22 on one side, and the front side of the recovery bin 10 is the side of the recovery bin 10 adjacent to the door 22, that is, the side with an opening 11.
[0024] Please see Figures 1 to 13 The automated low-temperature medical waste disposal device provided by this invention will now be described. The automated low-temperature medical waste disposal device includes a cold storage 20, several recycling cages 30, a data entry device 40, and a gripping component 50. A circular track 60 is provided on the top wall of the cold storage 20 and extends through the front side wall of the cold storage 20. Several recycling cages 30 are spaced apart within the cold storage 20 along the direction of the circular track 60. Each recycling cage 30 has an upward opening and is located below the circular track 60. The data entry device 40 is located on the front side of the cold storage 20 and is used to record information about the waste inside the garbage bags 1. The gripping component 50 is slidably connected to the bottom of the circular track 60 and is used to grip the garbage bags 1 and dispose of them into one of the recycling cages 30.
[0025] This application provides an automated low-temperature medical waste storage device. In actual use, the cold storage 20 adopts an insulated and sealed structure, preferably made of polyurethane insulation panels. The internal temperature can be adjusted to meet the low-temperature storage requirements of special medical waste such as pathological and infectious waste, preventing the medical waste from rotting and leaking. A ring track 60 is fixedly installed on the inner top wall of the cold storage 20 by expansion bolts. Its extension direction is adapted to the internal contour of the cold storage 20, and the ring track 60 passes through the front side wall of the cold storage 20, so that the two ends of the track are located inside the cold storage 20 and the front outside respectively (to facilitate the grabbing component 50 to connect to the externally delivered medical waste).
[0026] Several recycling cages 30 are arranged at intervals inside the cold storage 20 along the direction of the circular track 60, and are all located directly below the circular track 60. The recycling cages 30 are made of stainless steel and each recycling cage 30 has an upward opening. The number of recycling cages 30 can be set according to the medical waste classification requirements. For example, at least infectious, traumatic, chemical, and pathological recycling cages 30 can be set. The corresponding classification label is affixed to the outside of each recycling cage 30 to achieve dedicated storage of medical waste.
[0027] The data entry device 40 is located at the front of the cold storage 20, near the track passage. It preferably adopts a combination structure of touch screen and barcode scanner. Staff can scan the traceability code on the medical waste bag 1 (which is pasted on the garbage bag 1 in advance to record the medical waste depositor information, type, generation time, etc.) through the barcode scanner, or manually enter relevant information through the touch screen. The data entry device 40 is electrically connected to the subsequent grabbing component 50 and the control system of the cold storage 20 to realize the linkage between information and disposal action.
[0028] The gripping component 50 is slidably connected to the bottom of the circular track 60, including a sliding seat and a gripping claw. The sliding seat is adapted to the I-shaped slide rail of the circular track 60 and can slide freely along the track. The gripping claw adopts an electric gripping claw structure, and the inner side of the gripping claw is equipped with an anti-slip rubber pad to prevent the garbage bag 1 from slipping off during gripping. The gripping component 50 is linked with the data entry device 40. When the data entry device 40 confirms the type of medical waste, the control system controls the gripping component 50 to move along the circular track 60 to the top of the corresponding type of recycling cage 30, and then controls the gripping claw to release, accurately placing the garbage bag 1 into the recycling cage 30 to complete the storage action.
[0029] The automated low-temperature medical waste disposal device provided in this embodiment, compared with the prior art, achieves an automated process of medical waste information entry, accurate disposal, and classified storage by setting up multiple special recycling cages 30 for different categories and combining the linkage of data entry device 40 and gripping component 50. This completely replaces manual sorting, avoids mixing of different types of medical waste, and reduces the risk of cross-contamination.
[0030] The cold storage 20 provides a low-temperature environment, which can effectively inhibit the decay and bacterial growth of pathological medical waste (such as laboratory animal carcasses), while the sorting and recycling cage 30 achieves physical isolation between special medical waste and ordinary medical waste.
[0031] Automated disposal replaces manual operation, reducing labor intensity and avoiding classification errors caused by manual disposal. At the same time, medical waste information is traceable, providing clear information support for subsequent collection and disposal, and solving the problem of subsequent identification and handover difficulties.
[0032] In one possible implementation, the aforementioned cold storage 20 adopts, as follows: Figures 4 to 6 The structure shown is described in the following document. Figures 4 to 6The front side of the cold storage 20 is slidably connected to a transfer member 70 in the vertical direction. The transfer member 70 is provided with a hook 71 extending forward for hooking the lifting ear of the garbage bag 1. The transfer member 70 can move upward to transfer the garbage bag 1 onto the gripping component 50.
[0033] Specifically, the front side wall of the cold storage 20 (near the passage of the track) is provided with a slide rail extending vertically. The transmission component 70 is slidably connected to the slide rail. The transmission component 70 is fixedly provided with a hook 71 extending forward. The hook 71 is made of stainless steel and is used to stably hook the lifting ears of the garbage bag 1. The transmission component 70 is driven by an electric push rod or a screw.
[0034] The specific working process is as follows: The staff hangs the medical waste bag 1 with the traceability code attached on the hook 71. The medical waste information is entered through the data entry device 40. After the entry is completed, the control system controls the transfer component 70 to slide upward. When the transfer component 70 moves to a position level with the gripping component 50, the gripping component 50 moves above the waste bag 1 and controls the gripping claw to clamp the handle of the waste bag 1. The transfer component 70 returns to its original position, completing the transfer of the waste bag 1. The gripping component 50 then puts the waste bag 1 into the corresponding recycling cage 30.
[0035] To prevent staff from directly putting their hands into the low-temperature cold storage 20 to dispose of medical waste, the low-temperature environment can be reduced to minimize the harm to the human body. At the same time, it can reduce direct contact between people and medical waste, thereby reducing the safety hazards caused by medical waste leakage and pollution.
[0036] The hook 71 precisely hooks onto the lifting ear of the garbage bag 1, and works in conjunction with the smooth lifting and lowering of the transfer component 70 to prevent the garbage bag 1 from slipping or breaking during the transfer process, thus ensuring the continuity of the medical waste disposal process.
[0037] In some embodiments, see Figure 1 , Figure 2 and Figure 13 The outer cover of the cold storage 20 is provided with a recycling bin 10, which has an opening 11 facing the front. An entrance 21 is provided through the front wall of the cold storage 20, and a door 22 for sealing the entrance 21 is provided on the front wall of the cold storage 20. The door 22 is positioned opposite to the opening 11.
[0038] Specifically, the recycling bin 10 adopts a sealed box structure, covering the front of the cold storage 20 (covering the track passage, the transfer component 70, and the data entry device 40). The front of the recycling bin 10 has an opening 11 facing forward, and the edges of the opening 11 are sealed to facilitate operation by staff. An entrance 21 is provided through the front wall of the cold storage 20. The size of the entrance 21 is adapted to the size of the annular track 60 and the transfer component 70. The annular track 60 extends through the entrance 21 into the recycling bin 10. The transfer component 70 is located on one side of the entrance 21 (located outside the cold storage 20 but inside the recycling bin 10). A door 22 is connected to the front wall of the cold storage 20 by a hinge. The door 22 is an insulated and sealed door 12, which is set corresponding to the entrance 21 (for staff to enter and exit to retrieve and place the recycling cage 30). The edges of the door 22 are provided with sealing strips to seal the entrance 21, prevent cold air leakage from the cold storage 20, and prevent external pollutants from entering the cold storage 20.
[0039] The cold storage door 22 works in conjunction with the recycling bin 10 to effectively seal the entrance and exit 21 of the cold storage 20, reduce cold air leakage, lower the energy consumption of the cold storage 20, and maintain a stable low-temperature environment inside the cold storage 20 to ensure the safety of medical waste storage.
[0040] The recycling bin 10 can protect the transfer component 70 from external impacts and damage, thus extending the service life of the equipment.
[0041] In some embodiments, see Figures 1 to 3 The front wall of the recycling bin 10 is provided with a delivery port located on one side of the opening 11. A sealing door 12 for blocking the delivery port is slidably connected to the front wall of the recycling bin 10 in the horizontal direction. The transfer component 70 is located inside the recycling bin 10 and is arranged opposite to the sealing door 12. The data entry device 40 is arranged on the sealing door 12.
[0042] Specifically, on the front side wall of the recycling bin 10, a delivery port is provided through one side of the opening 11. The size of the delivery port is adapted to the size of a common medical waste bag 1, and is rectangular, so that staff can put the waste bag 1 into the recycling bin 10 through the delivery port. On the front side wall of the recycling bin 10, a slide rail is provided horizontally on the outside of the delivery port. The sealing door 12 is slidably connected to the slide rail. The size of the sealing door 12 is adapted to the delivery port and is used to seal the delivery port. The sealing door 12 adopts a sealing plate and has sealing strips on the edges to ensure the sealing performance after sealing.
[0043] The transfer device 70 is located inside the recycling bin 10 and is positioned opposite the delivery port and the sealing door 12. When the sealing door 12 is open, staff can directly hook the garbage bag 1 onto the hook 71 of the transfer device 70 through the delivery port without having to reach into the opening 11 of the recycling bin 10, making the operation more convenient. The data entry device 40 is integrated on the outer wall of the sealing door 12. Staff can first complete the data entry of medical waste information on the sealing door 12, and the sealing door 12 will automatically open and the garbage bag 1 will be delivered, realizing integrated operation of delivery and data entry. After delivery and data entry are completed, the sealing door 12 will automatically close, further improving the convenience of operation and sealing.
[0044] The delivery port works in conjunction with the sealing door 12, opening only when medical waste is being disposed of and automatically closing after disposal. This effectively reduces the entry of external pollutants into the recycling bin 10 and cold storage 20, while also reducing the leakage of medical waste odor and improving the operating environment.
[0045] The data entry device 40 is integrated into the sealing door 12. Staff members first complete the information entry and then put in the garbage bag 1. There is no need to operate back and forth in different locations, which shortens the operation time and improves work efficiency.
[0046] The opening of the sealing door 12 is linked to the information entry, which can prevent medical waste without information from being disposed of and ensure that every batch of medical waste can be traced.
[0047] In some embodiments, see Figure 3 The top of the sealing door 12 is slidably connected to the recycling bin 10, and the bottom is provided with a roller 13 that rolls with the recycling bin 10. A horizontally extending telescopic member 14 is provided on the front side wall of the recycling bin 10. One end of the telescopic member 14 is connected to the recycling bin 10, and the other end is connected to the sealing door 12.
[0048] Specifically, the top of the sealing door 12 is slidably connected to the slide rail on the front side wall of the recycling bin 10 via a slider. The slider and the slide rail are matched to ensure smooth sliding. Rollers 13 are provided on both sides of the bottom of the sealing door 12. The rollers 13 are rolled in cooperation with the bottom guide rail on the front side wall of the recycling bin 10 to reduce the friction when the sealing door 12 slides and prevent the sealing door 12 from getting stuck due to excessive weight.
[0049] On the front side wall of the recycling bin 10, a horizontally extending telescopic component 14 is fixedly installed on one side of the delivery port. The telescopic component 14 is preferably an electric telescopic rod. The fixed end of the electric telescopic rod is connected to the front side wall of the recycling bin 10 through a bracket, and the telescopic end is fixedly connected to the outer side wall of the sealing door 12. The electric telescopic rod is electrically connected to the control system, which can realize the automatic opening and closing of the sealing door 12. At the same time, the extension stroke of the electric telescopic rod is adjustable to ensure that the sealing door 12 can completely block the delivery port or completely open the delivery port to meet the delivery needs.
[0050] Furthermore, a position sensor is provided on the inner wall of the sealing door 12. When the sealing door 12 is fully closed, the sensor sends a signal to the control system. The control system confirms that the sealing door 12 is closed in place before the subsequent lifting and lowering action of the transfer component 70 can be carried out. If the sealing door 12 is not fully closed, the system issues an alarm prompt.
[0051] The dual sliding structure of the top slider and bottom roller 13, combined with the drive of the electric telescopic rod, prevents the sealing door 12 from sliding and getting stuck or shifting, ensuring that the sealing door 12 can accurately block or open the delivery port and improve the stability of the equipment operation.
[0052] The extension and retraction of the electric telescopic rod is controllable. Combined with the detection of the position sensor, it ensures that the sealing door 12 is closed in place to prevent external pollution.
[0053] The roller 13 reduces frictional wear between the sealing door 12 and the guide rail. The electric telescopic rod drive replaces manual pushing and pulling, reducing damage to the sealing door 12 and the guide rail caused by manual operation and improving the overall service life of the equipment.
[0054] In one possible implementation, the aforementioned crawling component 50 employs, as follows: Figure 4 , Figure 5 and Figures 7 to 9 The structure shown is described in the following document. Figure 4 , Figure 5 and Figures 7 to 9 The gripping component 50 includes a gripping slide 51, two gears 52, and two swing claws 53. The gripping slide 51 is slidably connected to the annular track 60. The two gears 52 are rotatably connected to the gripping slide 51 through the rotating shaft 54 and mesh with each other. The two swing claws 53 are fixedly connected to the two rotating shafts 54 one by one and are arranged opposite each other. The two swing claws 53 can swing towards each other to hook the handle of the garbage bag 1 or move away from each other to release the garbage bag 1.
[0055] Specifically, the gripping assembly 50 includes a gripping slide 51, two gears 52, and two pawls 53. The top of the gripping slide 51 is provided with a pulley assembly, which is embedded in the groove on the bottom surface of the annular track 60 and is tactilely connected to the annular track 60, allowing the entire gripping assembly 50 to move freely along the groove of the annular track 60. Both gears 52 are rotatably connected to the bottom of the gripping slide 51 via a rotating shaft 54. The two gears 52 mesh with each other to form a linkage structure. One of the rotating shafts 54 is connected to a micro motor, which is fixed on the gripping slide 51 and is used to drive the gears 52 to rotate.
[0056] Two swing claws 53 correspond one-to-one with two rotating shafts 54, and are fixed to the bottom of the rotating shafts 54 by key connection. The two swing claws 53 are arranged opposite each other, and the lower end of the swing claws 53 is arc-shaped with anti-slip rubber pads on the inner side to increase the friction with the lifting ears of the garbage bag 1. When the micro motor drives one of the gears 52 to rotate, the other gear 52 rotates in the opposite direction, causing the two swing claws 53 to swing towards each other or move away from each other: when it is necessary to grab the garbage bag 1, the micro motor rotates in the forward direction, and the two swing claws 53 swing towards each other and close, and their arc-shaped ends pass into the lifting ears of the garbage bag 1; when it is necessary to dispose of the garbage bag 1, the micro motor rotates in the reverse direction, and the two swing claws 53 move away from each other, releasing the lifting ears, and the garbage bag 1 falls into the corresponding recycling cage 30.
[0057] Two claws 53 are linked by gears 52 and inserted into the handles of the garbage bag 1. With the help of anti-slip rubber pads, they can stably grab medical waste bags 1 of different sizes and materials, preventing them from slipping or breaking during grabbing and ensuring the safety of medical waste disposal.
[0058] The gripping slide 51 can move precisely along the circular track 60, and the opening and closing action of the swing claw 53 is controllable, which can accurately put the garbage bag 1 into the corresponding recycling cage 30, avoiding classification errors caused by disposal deviation and further reducing the risk of cross-contamination.
[0059] The gear 52 linkage structure is simple and compact, occupies little space, and is suitable for the installation environment inside the cold storage 20. At the same time, it operates stably, has a low failure rate, and reduces equipment maintenance costs.
[0060] In one possible implementation, the aforementioned circular track 60 adopts, as shown in... Figure 4 , Figure 5 , Figure 7 , Figure 8 and Figure 10 The structure shown is described in the following document. Figure 4 , Figure 5 , Figure 7 , Figure 8 and Figure 10 A drive assembly 80 is slidably connected to the bottom of the circular track 60. The drive assembly 80 is connected to the gripping assembly 50 through a hinge rod 81. One end of the hinge rod 81 is hinged to the drive assembly 80, and the other end is hinged to the gripping assembly 50. The drive assembly 80 is used to drive the gripping assembly 50 to move.
[0061] Specifically, a drive assembly 80 is slidably connected to the bottom of the circular track 60. The drive assembly 80 is connected to the gripping assembly 50 via a hinge rod 81. One end of the hinge rod 81 is hinged to the bottom of the drive assembly 80 via a hinge seat, and the other end is hinged to the gripping slide 51 of the gripping assembly 50 via a hinge seat. The hinge rod 81 can rotate flexibly around the hinge seat to ensure that the gripping assembly 50 can adapt to the direction of the track during movement, while not affecting the opening and closing action of the swing claw 53.
[0062] The drive assembly 80 is electrically connected to the control system. The control system determines the position of the corresponding recycling cage 30 based on the medical waste information entered by the data entry device 40. Then, it controls the drive assembly 80 to move along the circular track 60, driving the gripping assembly 50 to move synchronously to the target position. When it is necessary to grab the garbage bag 1, the drive assembly 80 drives the gripping assembly 50 to move above the transfer member 70. When it is necessary to dispose of the garbage bag 1, the drive assembly 80 drives the gripping assembly 50 to move above the corresponding recycling cage 30. After moving to the position, the drive assembly 80 stops running, and the gripping assembly 50 performs the disposal action.
[0063] Furthermore, a position encoder is provided on the circular track 60 to detect the position of the drive component 80 and feed the position information back to the control system in real time. The control system adjusts the moving speed and stroke of the drive component 80 according to the position information to ensure that the gripping component 50 can be accurately positioned and avoid movement deviation.
[0064] The drive component 80 drives the gripping component 50 to move smoothly along the circular track 60. With the positioning of the position encoder, it ensures that the gripping component 50 can move accurately above the transfer component 70 or each recycling cage 30, avoiding placement errors caused by movement deviation and improving the accuracy of sorting and placement.
[0065] The hinge rod 81 can buffer the vibration during the movement of the gripping component 50, while adapting to the direction of the circular track 60, avoiding jamming or displacement of the gripping component 50, and ensuring long-term stable operation of the equipment.
[0066] The drive assembly 80 and the gripping assembly 50 are set separately and linked by the hinge rod 81, which can reduce the load on the drive assembly 80, reduce drive energy consumption, and facilitate the separate maintenance and replacement of the drive assembly 80 and the gripping assembly 50.
[0067] In some embodiments, see Figure 10 The drive assembly 80 includes a mating seat 82 and a drive seat 83. The mating seat 82 is slidably connected to the annular track 60, and the hinge rod 81 is hinged to the mating seat 82. The drive seat 83 is disposed on the mating seat 82, and a drive wheel 84 that is rotatably connected to the drive seat 83 and rolls with the bottom surface of the annular track 60 is driven by a rotation drive component 85.
[0068] Specifically, the drive assembly 80 includes a mating seat 82 and a drive seat 83. The top of the mating seat 82 is provided with a pulley assembly, which is embedded in the groove on the bottom surface of the annular track 60 and is in rolling contact with the annular track 60. The pulley assembly is in tight contact with the groove of the track to ensure that the mating seat 82 can slide smoothly along the track. One end of the hinge rod 81 is hinged to the bottom of the mating seat 82 to realize linkage with the gripping assembly 50. The drive seat 83 is fixed to the bottom of the mating seat 82 by bolts. Both sides of the drive seat 83 are rotatably connected to drive wheels 84. The drive wheels 84 are made of rubber and have anti-slip texture on the surface. They are in tight rolling contact with the bottom surface (outside the groove) of the annular track 60 to increase friction and prevent the drive wheels 84 from slipping.
[0069] The drive wheel 84 is driven by a rotary drive component 85, which is preferably a miniature geared motor. The miniature geared motor is fixed inside the drive base 83, and its output shaft is connected to the rotating shaft 54 of the drive wheel 84 through a coupling. The miniature geared motor is electrically connected to the control system. By adjusting the motor speed, the rotation speed of the drive wheel 84 can be controlled, thereby controlling the movement speed of the drive assembly 80 and the gripping assembly 50.
[0070] The mounting base 82 is precisely matched with the circular track 60. The drive wheel 84 is made of non-slip rubber. With the limit of the guide wheel, the drive component 80 is prevented from slipping or deviating when it moves, ensuring that the drive component 80 can drive the gripping component 50 and the garbage bag 1 to move smoothly and accurately.
[0071] The miniature geared motor has an adjustable speed, enabling precise control of the moving speed of the drive component 80. When the gripping component 50 moves to the target position, it can quickly decelerate and stop, avoiding positioning deviations caused by inertia.
[0072] The mounting base 82 and drive base 83 are set separately, which facilitates the individual processing, installation and maintenance of parts. When the drive wheel 84 or the geared motor is damaged, it can be replaced separately, reducing maintenance costs.
[0073] In some embodiments, see Figure 10 The drive seat 83 is provided with a horizontally extending reinforcing rod 90 located below the mating seat 82. The mating seat 82 is provided with a guide rod 91 that passes through the reinforcing rod 90 downward. An elastic member 92 located below the reinforcing rod 90 is sleeved on the guide rod 91. The lower end of the elastic member 92 is connected to the guide rod 91 and is used to push the reinforcing rod 90 upward so that the drive wheel 84 abuts against the annular track 60.
[0074] Specifically, a horizontally extending reinforcing rod 90 is fixedly provided on the drive seat 83. The reinforcing rod 90 is located below the mating seat 82 and is made of stainless steel. Both ends are fixedly connected to the two sides of the drive seat 83 to enhance the structural strength of the drive seat 83 and prevent the drive seat 83 from deforming due to excessive load. A downwardly extending guide rod 91 is fixedly provided at the bottom of the mating seat 82. The guide rod 91 is set perpendicular to the reinforcing rod 90. The lower end of the guide rod 91 passes through the reinforcing rod 90 and slides with the reinforcing rod 90. A limiting block is provided at the lower end of the guide rod 91 to limit the upward sliding stroke of the guide rod 91.
[0075] An elastic element 92 is fitted onto the guide rod 91. The elastic element 92 is preferably a compression spring. The elastic element 92 is located below the reinforcing rod 90. Its upper end abuts against the bottom of the reinforcing rod 90, and its lower end abuts against the limiting block of the guide rod 91. The compression spring is in a pre-compressed state and always generates an upward elastic force on the reinforcing rod 90. This force, in turn, drives the drive wheel 84 to abut against the bottom surface (outside the groove) of the annular track 60 through the drive seat 83, ensuring that there is always sufficient friction between the drive wheel 84 and the track.
[0076] When the drive assembly 80 encounters vibration during movement, or when the gripping assembly 50 grips a heavy garbage bag 1 causing load changes, the elastic element 92 can buffer the vibration through extension and retraction, while always keeping the drive wheel 84 in contact with the bottom surface of the track (outside the groove), preventing the drive wheel 84 from slipping or leaving the track; the guide rod 91 can limit the extension and retraction direction of the elastic element 92 to prevent the elastic element 92 from shifting, ensuring the buffering effect.
[0077] The reinforcing rod 90 enhances the rigidity of the drive seat 83, preventing it from deforming due to excessive load or vibration, and extending the service life of the drive assembly 80.
[0078] The pre-compression force of the elastic element 92 always keeps the drive wheel 84 pressed tightly against the annular track 60. Even if there is vibration or load change, it can prevent the drive wheel 84 from slipping or leaving the track, ensuring the driving force of the drive assembly 80 is stable and improving the reliability of equipment operation.
[0079] The elastic element 92 can buffer the vibration during the movement of the drive component 80, reduce the impact of vibration on the gripping component 50 and the garbage bag 1, prevent the garbage bag 1 from slipping or breaking due to vibration, and reduce the wear of equipment parts.
[0080] In one possible implementation, the aforementioned cold storage 20 adopts, as follows: Figure 12 and Figure 13 The structure shown is described in the following document. Figure 12 and Figure 13Two access openings 23 are provided on the front wall of the cold storage 20, respectively located near the two sides of the cold storage 20. A ring track 60 is provided through the two access openings 23. An isolation door 24 for blocking the access openings 23 is slidably connected on the front wall of the cold storage 20 in the vertical direction.
[0081] Specifically, two through-holes 23 are provided on the front side wall of the cold storage 20. The two through-holes 23 are respectively located near the left and right sides of the cold storage 20, and the spacing is adapted to the overall width of the annular track 60. The two ends of the annular track 60 pass through the two through-holes 23 and extend to the front exterior of the cold storage 20 (connecting with the recovery bin 10). The size of the through-holes 23 is adapted to the size of the annular track 60 to ensure that the annular track 60 (including the bottom groove) can pass through smoothly, while minimizing the gap of the through-holes 23 to reduce cold air leakage.
[0082] On the front wall of the cold storage 20, there are vertically extending slide rails on the outside of each access opening 23. The isolation door 24 is slidably connected to the slide rail. The isolation door 24 is made of heat-insulating sealing plate, and its size is adapted to the access opening 23 to block the access opening 23. The top of the isolation door 24 is connected to an electric push rod, which is fixed to the top of the front wall of the cold storage 20. The extension and retraction of the electric push rod drives the isolation door 24 to slide up and down along the slide rail, thereby opening and closing the access opening 23.
[0083] The isolation door 24 is electrically connected to the control system and is linked with the drive assembly 80: when the drive assembly 80 moves the gripping assembly 50 to the vicinity of the passage 23 and needs to pass through the passage 23, the control system controls the isolation door 24 on the corresponding side to slide downward and open, so that the passage 23 can be passed through by both the drive assembly 80 and the gripping assembly 50; after the drive assembly 80 and the gripping assembly 50 (with or without the garbage bag 1) have completely passed through the passage 23, the isolation door 24 automatically slides upward and closes, blocking the passage 23; if there is no need to move the gripping assembly 50, the isolation door 24 is always in the closed state to ensure the airtightness of the cold storage 20.
[0084] The isolation door 24 can completely block the passage 23 when the drive component 80 is not in use, preventing cold air in the cold storage 20 from leaking out of the passage 23, reducing the energy consumption of the cold storage 20, and maintaining a stable low-temperature environment inside the cold storage 20 to ensure the safety of medical waste storage.
[0085] The isolation door 24 is linked with the drive assembly 80 to prevent the drive assembly 80 and the gripping assembly 50 from colliding with the isolation door 24 when they move. At the same time, it prevents external dust and debris from entering the cold storage 20 through the passage 23 and contaminating the medical waste.
[0086] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
