Description

Technical Field

[0001] This invention relates to the field of medical waste treatment, and more particularly to a container clamping and tilting device and system for medical waste treatment plants. Background Technology

[0002] Medical waste is classified as hazardous waste, and if not handled properly, it may lead to the secondary spread of viruses or bacteria. In order to achieve unmanned medical waste disposal, medical waste is usually stored in special square barrel-shaped containers. After being transported to a designated location, it is picked up by a robotic arm or special mechanism and dumped into the boiler feed port. This device is usually driven by sensors to initiate action commands, but due to the influence of external factors or sensor malfunction, the picking may fail, causing the entire production line to malfunction.

[0003] Therefore, it is necessary to design a new container clamping and pouring device for medical waste treatment plants to overcome the above problems. Summary of the Invention

[0004] The purpose of this invention is to overcome the defects of the prior art and provide a container clamping and tilting device for medical waste treatment plants, so as to achieve stable clamping of containers in medical waste treatment plants, reduce the number of related sensors, reduce costs and failure rates, thereby improving work efficiency. This invention solves at least some of the problems in the prior art.

[0005] This invention is implemented as follows:

[0006] This invention provides a container clamping and tilting device for medical waste treatment plants, including a fixed frame. The fixed frame includes a front plate, a back plate, and a driving component for flipping the back plate. The front plate is fixed to the back plate. Two gears are provided on the side of the front plate facing the back plate. A clamping arm is fixed on each gear. The two gears are rotatably connected to the front plate. A rack is provided between the two gears to drive the two gears so that the two clamping arms clamp the container. A rack connecting rod is provided at the bottom of the rack, which can move downward under the gravity of the container. A rack support rod is also provided on the rack. A rack support rod slot is provided on the back plate.

[0007] Furthermore, the rotation axis of the back plate is located at the bottom of the back plate, and the rotation axis is driven by a rotary motor.

[0008] Furthermore, the rack support rod slot is provided with a trigger switch for turning on the rotary motor.

[0009] Furthermore, the back plate is also provided with a reset mechanism for disengaging the rack support rod from the rack support rod slot.

[0010] Furthermore, the rack and pinion linkage is connected to the front plate via an elastic element.

[0011] Furthermore, the elastic element is a spring.

[0012] Furthermore, the clamping arm is used to hold the inner wall of the container, on which a rubber pad is installed to increase friction.

[0013] The present invention also provides a container clamping and tilting system for medical waste treatment plants, including a conveyor belt for conveying containers containing medical waste, and the aforementioned container clamping and tilting device for medical waste treatment plants.

[0027] 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.

[0028] like Figures 1-6 Embodiment 1 of the present invention provides a container clamping and tilting device for a medical waste treatment plant, including a fixed frame. The fixed frame includes a front plate 1, a back plate 2, and a driving component for flipping the back plate. The front plate 1 is fixed to the back plate 2. Two gears 3 are provided on the side of the front plate 1 facing the back plate 2. A clamping arm 4 is fixed on each gear 3. The two gears 3 are rotatably connected to the front plate 1. A rack 6 is provided between the two gears 3, which can drive the two gears to clamp the two clamping arms to clamp the container 5. A rack connecting rod 7 is provided at the bottom of the rack 6, which can move downward under the action of the container's gravity. A rack support rod 8 is also provided on the rack 6. A rack support rod slot 9 is provided on the back plate 2. The container contains medical waste. The weight of the container causes the rack support rod 8 to be pressed down along the rack support rod guide groove 10 into the rack support rod slot 9. The entrance of the rack support rod slot 9 is a narrow opening 11, which limits the rack support rod 8. The tension of the spring is insufficient to make the rack support rod 8 move upward through the narrow opening. Figure 5The diagram shows the shapes of the rack support guide groove 10 and rack support slot 9 on the back plate 2. Under the gravity of the container, the rack connecting rod 7 moves downward, causing the rack 6 to move downward. The downward movement of the rack 6 causes the rack support 8 to move downward along the rack support guide groove 10 and into the rack support slot 9. In this embodiment, the rack connecting rod 7 is connected to the front plate 1 by a spring 13. The clamping arm 4 is used to clamp the container, and a rubber pad for increasing friction is installed on the inner wall. This invention provides a device for clamping a container by gravity. This invention relies on its own structure to sense whether a container has been delivered to a designated position, reducing the workflow of manual identification and control; this invention does not rely on sensors, effectively reducing the equipment failure rate and improving the overall operating efficiency of the system.

[0029] The rotating shaft 12 of the back plate 2 is located at the bottom of the back plate 2, and the rotating shaft 12 is driven by a rotary motor. When it is necessary to pour medical waste from container 5 into the boiler receiving hopper 16, such as... Figure 4 The back plate 2 rotates away from the conveyor belt 14; in other embodiments, a cam mechanism can also be used to drive the back plate 2 to rotate. A trigger switch for starting the rotary motor is provided in the rack support slot 9. After the rack support 8 enters the rack support slot 9, it contacts the trigger switch, which sends a signal to the rotary motor, causing the rotary motor to start rotating; in other embodiments, the trigger switch can also be configured as an inductive type.

[0030] When the rack and pinion rod 8 is confined within the rack and pinion rod slot 9, the clamping arm 4 ensures that the container 5 is always clamped. The back plate 2 also has a reset mechanism to disengage the rack and pinion rod 8 from the rack and pinion rod slot 9. After the medical waste in the container is emptied, the container returns to the conveyor belt 14. At this time, the reset mechanism applies an upward force to the rack and pinion rod 8, causing it to disengage from the rack and pinion rod slot 9. After disengaging from the slot 9, the rack and pinion rod 8 moves upward under the spring tension, and the clamping arm 4 releases the container 5. The reset mechanism can use a cylinder or motor to apply an upward force to the rack and pinion rod 8.

[0031] Embodiment 2 of the present invention provides a container clamping and tilting system for medical waste treatment plants, including a conveyor belt 14 for conveying containers 5 containing medical waste, and the aforementioned container clamping and tilting device for medical waste treatment plants. A fixed frame is mounted on one side of the conveyor belt along its width. A plurality of conveyor rollers 15 are provided on the conveyor belt, spaced apart along the conveying direction of the waste container. A rack and pinion linkage 7 is located between adjacent conveyor rollers 15. The system also includes a boiler for disposing of medical waste, located on the side of the fixed frame away from the conveyor belt. In this embodiment, two gears 3 are symmetrically arranged on both sides of the rack 6 along the container conveying direction.

[0032] In the initial stage, the clamping arm 4 is raised to avoid obstructing the container 5 containing medical waste from entering the clamping area. When the container 5 is transported to the rack and pinion linkage 7 by the conveyor belt 14, the weight of the container drives the rack and pinion linkage 7 to move towards the ground, simultaneously causing the rack 6 to move downwards, causing the clamping arm 4 to naturally droop and clamp the container 5. The key point of the rack and pinion linkage is to ensure that the clamping arm can grip the container when it is fully loaded, and to allow the clamping arm to naturally release when the container is unloaded. The contact depth between the rack and pinion linkage and the container needs to be adjusted. Furthermore, in this embodiment, the clamping arm drive gear and the clamping arm are arranged opposite each other; that is, the left clamping arm drive gear drives the right clamping arm, and the right clamping arm drive gear drives the left clamping arm. To avoid interference between the clamping arm near the fixed frame and the drive gear during operation, the clamping arm structure can be adjusted, such as... Figure 3 An avoidance section 17 can be provided on the clamping arm.

[0033] When the container containing medical waste moves to the front of the front panel 1, the container's own weight causes the rack and pinion 7 to move downwards. Simultaneously, the rack 6 moves downwards, driving the gear 3 to rotate, causing the clamping arm 4 to move downwards and clamp the container. At the same time, the rack support rod 8 is confined within the rack support rod slot 9 on the back panel 2, preventing it from moving upwards, and the clamping arm 4 maintains its clamping position. After the rack support rod 8 enters the rack support rod slot 9, it contacts the trigger switch within the slot 9. The trigger switch sends a signal to the rotating motor, which begins to run, causing the back panel 2 to rotate around its bottom. The rotating shaft 12 rotates clockwise, pouring the medical waste from the container into the boiler receiving hopper 16 and then resetting. The container rotates back onto the conveyor belt, and the resetting mechanism applies an upward force to the rack support rod 8, causing the rack support rod 8 to disengage from the rack support rod slot 9. This completes one pouring action. As the container becomes lighter after emptying the medical waste, the rack support rod 8 moves upward under the tension of the spring 13, causing the rack 6 to move upward. The gear 3 rotates, causing the clamping arm 4 to rise and separate from the container 5, no longer clamping the container 5. The conveyor belt 14 then transports the container 5 to the designated location for stacking, completing one operation cycle.

[0034] This invention eliminates the need for sensor control, simplifying the existing control process, reducing the failure rate, and improving overall operating efficiency. It utilizes the material container's own gravity for positioning and gripping, simplifying the manual process of identifying material location and initiating gripping.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
