Description
Technical Field
[0001] This invention relates to a trash can, and more particularly to an automatic cable tie medical waste can. Background Technology
[0002] Medical institutions and disease control centers generate large amounts of medical waste daily. To effectively address the potential for disease transmission from medical waste, reduce the risk of epidemic spread, and strengthen the last line of defense against the pandemic, standardized medical waste disposal is crucial. Among the key aspects of medical waste disposal, the sealing of medical waste packaging bags is paramount, and its proper handling directly impacts the quality of medical waste management. According to Article 13 of the "Regulations on the Management of Medical Waste in Medical and Health Institutions," when medical waste reaches three-quarters of the packaging or container's capacity, an effective sealing method must be used to ensure a tight and airtight seal. An effective sealing method is the "gooseneck" seal, which is particularly important for infectious medical waste bags to prevent hazardous waste and gases from contaminating the outside environment.
[0003] In existing technologies, ordinary trash cans can only be used to hold trash bags; they cannot seal the bags, let alone create a "gooseneck" seal. For infectious medical waste bags, gooseneck sealing is often done manually. While some existing smart trash cans can automatically rotate the trash bags to create a spiral linear structure at the top, they cannot bend this linear structure into a U-shape and tie it up. This still requires manual tying, which is not only labor-intensive but also poses a safety risk, as the highly polluting substances in the medical waste can easily contaminate the outside environment or the operators. Summary of the Invention
[0004] The purpose of this invention is to provide an automatic cable-locking medical waste bin. This invention features automated venting and gooseneck-style sealing of the waste bag, improving safety.
[0005] The technical solution of the present invention: An automatic cable tie medical waste bin includes a bin body, inside which is a movable fixing ring and an automatic cable tie device. Several telescopic grippers are slidably connected along the circumferential direction on the inner ring surface of the fixing ring. A base is provided below the fixing ring, and a rotating platform is rotatably connected to the base. A rotary motor for driving the rotating platform to rotate is provided inside the base. A pusher for driving the fixing ring to move up and down is provided on the base. A clamping device is provided on the rotating platform, and a stop bar assembly located below the fixing ring is provided on the clamping device.
[0006] In the aforementioned automatic cable tie medical waste bin, an annular slide rail is provided on the inner ring surface of the fixing ring, and a plurality of electrically controlled sliders are provided on the annular slide rail, the electrically controlled sliders being fixedly connected to the telescopic gripper.

The fixed end of the electrically controlled telescopic rod is fixedly connected to an electrically controlled slider, and the movable end of the electrically controlled telescopic rod is fixedly connected to the electrically controlled clamp.
[0008] In the aforementioned automatic cable tie medical waste bin, the clamping device includes several clamping plates located around the waste bag, with the multiple clamping plates symmetrically distributed. The inner wall of the bin is provided with a moving drive that drives the symmetrical clamping plates to move closer or further apart. The inner wall of the bin is also provided with an exhaust hole, and a one-way valve is provided in the exhaust hole.
[0009] In the aforementioned automatic cable tie medical waste bin, the baffle assembly includes a fixed rod, one end of which is connected to a clamping plate, and the other end of which is provided with a horizontally distributed electric telescopic rod.
[0010] In the aforementioned automatic cable tie medical waste bin, an exhaust pipe is connected to the exhaust port, the outlet end of the exhaust pipe is connected to the waste gas treatment box, and an air inlet is also provided on the inner wall of the bin body, with an air inlet pipe provided on the air inlet, the inlet end of the air inlet pipe being connected to the waste gas treatment box.
[0011] In the aforementioned automatic cable tie medical waste bin, the exhaust gas treatment box includes a box body, inside which is provided an isolation plate and an ultraviolet disinfection lamp. The isolation plate divides the internal space of the box body into a first treatment chamber and a second treatment chamber. The first treatment chamber is connected to an exhaust pipe, and the second treatment chamber is connected to an air inlet pipe. The first treatment chamber contains aerosol-dissolving water, and a heater is provided at the bottom of the first treatment chamber. The second treatment chamber is provided with a filter layer, with an inlet above the filter layer and an outlet below the filter layer connected to the air inlet pipe. The ultraviolet disinfection lamp passes through the isolation plate, with one part of the ultraviolet disinfection lamp placed in the first treatment chamber and the other part of the ultraviolet disinfection lamp placed in the second treatment chamber.
[0012] In the aforementioned automatic cable tie medical waste bin, the automatic cable tie device includes a pair of brackets, a rotating shaft rotatably connected to the brackets between the two brackets, a rotating motor driving the rotating shaft to rotate at one end of the rotating shaft, a curved arm on the rotating shaft, and a cable tie machine at the outer end of the curved arm.
[0013] In the aforementioned automatic cable tie medical waste bin, the bin body is further equipped with a controller, the bin body is equipped with a bin lid, the bin lid is equipped with a replacement button and an open button, and the replacement button, open button, automatic cable tie device, telescopic gripper, stop bar assembly, fixing ring, pusher, and clamping device are all connected to the controller.
[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0015] The rotating platform in this invention is used to hold empty garbage bags. The bag opening loop is fitted over the fixing ring for easy garbage disposal. When the garbage bag is about 2 / 3 full, the retractable clamp on the fixing ring closes and secures the bag opening, while the clamping device clamps the bottom of the garbage bag. The rotating platform causes the bottom of the garbage bag to rotate, resulting in a spiral twisting structure at the top of the garbage bag, which simultaneously expels harmful gases from inside the garbage bag.
[0016] After the upper part of the garbage bag forms a spiral twist structure, a pusher is installed to drive the fixing ring to move down, so that the twisted garbage bag opening passes over the baffle assembly from top to bottom to form a U-shaped structure. An automatic tie-up device is installed to tie the two ends of the U-shaped opening of the garbage bag together to form a gooseneck pack, thereby realizing the automated operation of medical waste bags from rotating the opening to tying them tightly, reducing the workload of medical staff and the risk of infection, and improving safety.

[0022] The present invention will be further described below with reference to embodiments, but these embodiments are not intended to limit the scope of the invention.
[0023] Example:
[0024] like Figures 1-4As shown, an automatic cable tie medical waste bin includes a bin body 1. Inside the bin body 1, there is a movable fixing ring 2 and an automatic cable tie device 3. Several telescopic grippers 22 are slidably connected along the circumferential direction on the inner ring surface of the fixing ring 2. A base 4 is provided below the fixing ring 2. A rotating platform 41 is rotatably connected to the base 4. A rotary motor that drives the rotating platform 41 to rotate is provided inside the base 4. A pusher 42 that drives the fixing ring 2 to move up and down is provided on the base 4. A clamping device 5 is provided on the rotating platform 41. A stop bar assembly 6 located below the fixing ring 2 is provided on the clamping device 5.
[0025] The rotating platform 41 is used to hold empty garbage bags 8. The opening of the garbage bag 8 is looped around the fixed ring 2, thus filling the garbage bag 8 with an open opening for easy garbage disposal. When the garbage bag 8 is about 2 / 3 full of waste, the opening of the garbage bag 8 is closed and secured by the telescopic clamps 22 on the fixed ring 2. There are at least three telescopic clamps 22 on the fixed ring 2. At the same time, the clamping device 5 clamps the bottom of the garbage bag 8. The rotating platform 41 rotates under the drive of the rotating motor, causing the bottom of the garbage bag 8 to rotate. A slide rail can be provided between the rotating platform 41 and the base 4 to ensure smooth rotation. At this time, since the top edge of the garbage bag 8 is fixed in place by the telescopic clamps 22, the bottom of the garbage bag 8 rotates, resulting in a spiral twisting structure at the top of the garbage bag 8, while simultaneously expelling harmful gases from inside the garbage bag 8.
[0026] After the upper part of the garbage bag 8 forms a spiral twist structure, the pusher 42 is used to drive the fixing ring 2 to move down, so that the opening of the twisted garbage bag 8 passes around the baffle assembly 6 from top to bottom to form a U-shaped structure. The automatic tie-up device 3 is used to tie the two ends of the U-shaped opening of the garbage bag 8 together to form a gooseneck pack, thereby realizing the automated operation of the medical waste bag 8 from rotating the opening to the tie-up sealing, reducing the workload of medical staff and the risk of infection, and improving safety.
[0027] The actuator 42 is an electric cylinder.
[0028] The inner ring surface of the fixed ring 2 is provided with an annular slide rail 21, and several electrically controlled sliders are provided on the annular slide rail 21. The electrically controlled sliders are fixedly connected to the telescopic gripper 22. The telescopic gripper 22 moves circumferentially on the annular slide rail 21 through the electrically controlled sliders, thereby adjusting the fixed position of the bag opening of the garbage bag 8 and avoiding interference with the twisting, bending, and tying actions of the garbage bag 8. Moreover, when the rotating table 41 is not rotating, the bag opening of the garbage bag 8 can also be twisted by rotating the telescopic gripper 22, which plays a secondary protective role.
[0029] The telescopic gripper 22 includes an electrically controlled telescopic rod 23 and an electrically controlled clamp 24. The fixed end of the electrically controlled telescopic rod 23 is fixedly connected to an electrically controlled slider, and the movable end of the electrically controlled telescopic rod 62 is fixedly connected to the electrically controlled clamp 24. By extending and retracting the electrically controlled telescopic rod 23, the position of the electrically controlled clamp 24 can be adjusted, and the clamp 24 can be tightened or loosened. With the combined action of multiple telescopic grippers 22, the opening of the garbage bag 8 can be closed or opened.
[0030] The clamping device 5 includes several clamping plates 51 located around the garbage bag 8, symmetrically distributed. A moving actuator 52 is provided on the inner wall of the bin 1 to drive the symmetrically arranged clamping plates 51 closer together or further apart. An exhaust port with a one-way valve is also provided on the inner wall of the bin 1 to prevent gas backflow. The moving actuator 52 is an electric cylinder. Driven by the moving actuator 52, the clamping plates 51 press and fix the garbage bag 8 containing waste, preventing the garbage bag 8 from tipping over due to inertia, and squeezing out harmful gases generated inside the garbage bag 8, which are then discharged through the exhaust port.
[0031] The baffle assembly 6 includes a fixed rod 61, one end of which is connected to the clamping plate 51, and the other end of which is provided with a horizontally distributed electric telescopic rod 62. The baffle assembly 6 is connected to the clamping plate 51 and can move with the clamping plate 51, reducing the space occupied by the baffle assembly 6 when not in use and avoiding the space for the garbage bag 8 to bend when in use. This allows the garbage bag 8 to smoothly pass around the electric telescopic rod 62 to form a U-shaped structure, facilitating the tying of the garbage bag 8.
[0032] An exhaust pipe 53 is connected to the exhaust port, and the outlet end of the exhaust pipe 53 is connected to the waste gas treatment box 7. An air inlet is also provided on the inner wall of the bin body 1, and an air inlet pipe 54 is provided on the air inlet. The inlet end of the air inlet pipe 54 is connected to the waste gas treatment box 7. Harmful gases inside the trash can are discharged into the waste gas treatment box 7 through the exhaust pipe 53 for harmless treatment. External air enters the waste gas treatment box 7, is filtered and disinfected, and then enters the trash can.
[0033] The exhaust gas treatment box 7 includes a box body 71, inside which is provided an isolation plate 72 and an ultraviolet disinfection lamp 73. The isolation plate 72 divides the internal space of the box body 71 into a first treatment chamber 74 and a second treatment chamber 75. The first treatment chamber 74 is connected to the exhaust pipe 53, and the second treatment chamber 75 is connected to the air inlet pipe 54. The first treatment chamber 74 contains aerosol dissolved water 76, and a heater 77 is provided at the bottom of the first treatment chamber 74. The second treatment chamber 75 is provided with a filter layer 78, with an inlet at the top of the filter layer 78 and an outlet at the bottom of the filter layer 78 connected to the air inlet pipe 54. The ultraviolet disinfection lamp 73 passes through the isolation plate 72, with a part of the ultraviolet disinfection lamp 73 placed in the first treatment chamber 74 and the other part of the ultraviolet disinfection lamp 73 placed in the second treatment chamber 75.
[0034] Harmful gases inside the trash can enter the first treatment chamber 74, where they are disinfected by ultraviolet disinfection lamp 73 and dissolved by aerosol-dissolving water 76. External gases enter the second treatment chamber 75, where they are filtered by filter layer 78 and disinfected by ultraviolet disinfection lamp 73 before entering the trash can. Through holes can also be provided on the partition plate 72 to achieve gas circulation and purification within the trash can.
[0035] The automatic tying device 3 includes a pair of supports 31, with a rotating shaft 32 rotatably connected between the two supports 31. One end of the rotating shaft 32 is equipped with a rotating motor 33 that drives its rotation. A curved arm 34 is mounted on the rotating shaft 32, and a tying machine 35 is mounted on the outer end of the curved arm 34. The curved arm 34 has an arc shape that matches the inner wall of the waste bin, without affecting the placement space of the waste bag 8. During daily use of the medical waste bin, the automatic tying device 3 can be placed on the side wall of the medical waste bin without affecting the normal use of the waste bag 8. When it is necessary to tie and seal the waste bag 8, the rotating motor 33 drives the curved arm 34 to rotate via the rotating shaft 32, adjusting the position of the tying machine 35 so that it moves to the position where the waste bag 8 needs to be tied, allowing the tying machine 35 to accurately tie the opening of the waste bag 8. After tying, it automatically rotates back, realizing the automatic tying function of the waste bag 8.
[0036] The barrel body 1 is also equipped with a controller, which can be a PLC control board. The barrel body 1 is equipped with a barrel cover 11, and the barrel cover 11 is equipped with a replacement button 12 and an open button 13. The replacement button 12, the open button 13, the automatic cable tie device 3, the telescopic clamp 22, the stop bar assembly 6, the fixing ring 2, the pusher 42, the clamping device 5, and the rotary motor are all connected to the controller to complete the automatic control of each electrical appliance.
[0037] When disposing of garbage, the lid 11 can be opened by pressing the open button 13, thereby disposing of garbage into the garbage can.
[0038] When changing garbage bag 8, press the change button 12 to open the lid 11 and change the garbage bag 8.
[0039] Garbage bag 8 replacement process: When the replacement button 12 is pressed, the symmetrical clamping plates 51 move closer to each other, squeezing and fixing the garbage bag 8 containing waste. The polluted gas containing aerosol squeezed out of the garbage bag 8 enters the exhaust gas treatment box 7 through the exhaust pipe 53 for harmless treatment. The harmless gas then enters the interior of the garbage can through the air inlet pipe to complete the gas purification.
[0040] The electrically controlled clamps 24 approach each other under the action of the electrically controlled telescopic rod 23, closing and fixing the opening of the garbage bag 8. Then, the rotary motor drives the rotating table 41 and the clamping plate 51 to rotate, thereby causing the bottom of the garbage bag 8 to rotate, while the opening of the garbage bag 8 is locked by the electrically controlled clamps 24, keeping its position stationary, so that the upper part of the garbage bag 8 is rotated into a spiral twisted state. Then, the pusher 42 drives the fixing ring 2 to move downward, and the telescopic clamps 22 on the fixing ring 2 corresponding to the baffle assembly 6 retract, while the other telescopic clamps 22 move to the other side of the baffle assembly 6, avoiding interference with the baffle assembly 6 without affecting the closing of the bag opening. During the downward movement of the fixing ring 2, the electric telescopic rod 62 of the baffle assembly 6 extends and supports the bottom of the opening of the garbage bag 8, so that as the telescopic clamps 22 pull the opening of the bag to continue to move downward, the opening of the bag passes over the baffle assembly 6 from top to bottom to form a U-shaped structure.
[0041] After the U-shaped structure of the opening of the garbage bag 8 is completed, the rotating motor 33 in the automatic tying device 3 drives the curved arm 34 and the tying machine 35 to rotate into position, so that the tying machine 35 can tie and fix the two ends of the U-shaped opening of the garbage bag 8 in a gooseneck style, thus completing the sealing process of the garbage bag 8.
[0042] After the garbage bag 8 is sealed, the electric telescopic rod 62 retracts from the U-shaped bend at the opening of the garbage bag 8, and each electric clamp 24 releases its grip on the opening of the garbage bag 8 and resets. The clamping plate 51 returns to its original position under the control of the mobile driver 52, releasing the bottom of the clamped garbage bag 8, making it easier for staff to take out the gooseneck-tied and packaged garbage bag 8.
[0043] Then, the staff placed the clean garbage bag 8 on the rotating platform 41 inside the bin, turned the opening of the garbage bag 8 outward and put it on the fixing ring 2, and clamped and fixed the edge of the opening of the garbage bag 8 by the telescopic clamp 22, so that the garbage bag 8 is in an open state, and then closed the bin lid 11.
