Description

Technical Field

[0001] This invention relates to the field of medical waste recycling, and more particularly to an automatic sorting, collection, and sealing packaging device for medical waste based on pneumatic drive. Background Technology

[0002] In the medical field, the sorting and sealing of medical supplies (including medical waste and discarded consumables) is a crucial step in ensuring medical safety and preventing cross-contamination. Currently, the sorting of medical supplies largely relies on manual operation, which has several drawbacks: manual sorting is inefficient and cannot meet the large-volume sorting needs of hospitals and medical laboratories. Furthermore, prolonged operation can lead to worker fatigue, resulting in sorting errors and the mixing of different types of medical supplies, increasing the risk of contamination. Additionally, manual sorting requires separate sealing, a cumbersome process where the sealing effectiveness is greatly affected by the standardization of manual operation, easily leading to leaks, environmental pollution, or the spread of pathogens.

[0003] A search revealed patent publication number CN212884091U, which discloses a rapid medical waste processing device. The technical problem is to provide a rapid medical waste processing device where users simply place medical waste into a conveying funnel, then push a pusher block and start a motor to cut and compress the used medical waste, which is then swept into a collection bin. The device includes a mounting base and a conveying mechanism; the mounting base is equipped with the conveying mechanism; and a cutting mechanism is also mounted on the mounting base. After the medical waste is pushed to the appropriate position, the motor is started. The motor output shaft drives a first rotating block to rotate, which in turn drives a second rotating block to rotate a third rotating block, causing a cutting blade to move up and down within a second fixed block to cut the medical waste on the first fixed block.

[0004] The existing automated sorting devices are few in number, but most only have a single sorting function and lack a matching sealing and collection structure. After sorting, manual sealing is still required, which cannot achieve integrated sorting and sealing operations and has limited overall efficiency improvement. In addition, the flow guiding structure of some sorting devices is poorly designed, which can easily lead to material jamming and spillage, resulting in insufficient sorting accuracy. Furthermore, the power transmission structure of the existing devices has poor stability and is prone to deviation and shaking during operation, affecting the continuity and reliability of sorting and sealing.

[0005] In view of the shortcomings of the existing technologies, there is an urgent need for a device that can achieve integrated operation of automatic identification, classification and diversion and sealed collection of medical items, and that is stable in operation, accurate in sorting and highly efficient. This device would solve the defects of traditional manual sorting and existing automated devices, meet the standardized and efficient requirements of the medical field for the sorting and sealing of medical items, reduce labor costs and pollution risks, and ensure medical safety. Summary of the Invention

[0006] The purpose of this invention is to address the problems existing in the background art by proposing an automatic sorting, collection, and sealing packaging device for medical waste based on pneumatic drive.

The transfer platform is divided into three layers. Each layer of the transfer platform is connected to a flow guide frame one, a flow guide frame three, and a flow guide frame two from top to bottom on one side. A mounting frame two is provided on one side of the transfer platform. The surface of the mounting frame 2 is provided with feed inlet 1, feed inlet 2 and feed inlet 3 in sequence, and heat sealing machine is provided at the lower end of feed inlet 1, feed inlet 2 and feed inlet 3.

[0008] Preferably, the pneumatic mechanism further includes a mounting base, which is fixed to the lower end of the mounting frame.

[0009] Preferably, an air pump is fixed at one end of the mounting bracket. The air pump works in conjunction with a cylinder. A rod is provided on one side of the cylinder. One side of the rod is rotatably connected to the lower end of the rotating plate to provide stable power output to the cylinder, realize the extension and retraction drive function of the rod, and drive the rotating plate to rotate flexibly.

[0010] Preferably, the lower ends of the mounting bracket 1, mounting bracket 2, and transfer platform are fixed with supports, and the lower ends of the supports are fixed with bases, so as to realize the stable support and fixation function of each component of the device, improve the overall structural integrity of the device, and prevent displacement caused by vibration during device operation.

[0011] Preferably, a controller is fixed at one end of the mounting frame, a motor is provided on one side of the mounting frame, and a conveyor belt is provided at the upper end of the mounting frame.

[0013] Preferably, the inclination angle of the flow guide frame 1, flow guide frame 3 and flow guide frame 2 is 15 degrees, and one end of the flow guide frame 1, flow guide frame 3 and flow guide frame 2 is flush with one side of the feed inlet 1, feed inlet 2 and feed inlet 3, which facilitates accurate feeding and realizes the smooth flow and precise feeding of materials after sorting. The 15-degree inclination angle ensures that the materials slide down smoothly by their own gravity.

[0014] Preferably, a fixed base is fixed at the lower end of the second mounting bracket, and a rod is inserted into the fixed base. Movable bracket one and movable bracket two are fixed on opposite sides of the rods on both sides, so as to realize the stable guidance and limiting functions of movable bracket one and movable bracket two.

[0022] To make the above-mentioned objectives, features and advantages of the present invention more readily understood, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0024] Secondly, the present invention will be described in detail with reference to the schematic diagrams. When describing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure will be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include the three-dimensional spatial dimensions of length, width, and depth.

[0025] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0026] Example 1 Please see Figures 1-2 As shown, this embodiment is an automatic sorting, collection and sealing packaging device for medical waste based on pneumatic drive, including a mounting frame 1. A pneumatic mechanism is provided on one side of the mounting frame 1. The pneumatic mechanism includes a cylinder 20 and a rotating plate 5. The cylinder 20 is located below the mounting frame 1, and the rotating plate 5 is rotatably mounted on one side of the mounting frame 1. A transfer platform 6 is provided on one side of the pneumatic mechanism. The transfer platform 6 is divided into three layers. Each layer of the transfer platform 6 is connected from top to bottom to a flow guide frame 7, a flow guide frame 3 13 and a flow guide frame 2 11. A mounting frame 2 10 is provided on one side of the transfer platform 6. The surface of the mounting bracket 2 10 is provided with feed inlet 1 9, feed inlet 2 8 and feed inlet 3 12 in sequence, and heat sealing machine 21 is provided at the lower end of feed inlet 1 9, feed inlet 2 8 and feed inlet 3 12.

[0027] The pneumatic mechanism also includes a mounting base 26, which is fixed to the lower end of the mounting frame 1. A rotating seat 25 is rotatably mounted in the middle of the mounting base 26. The cylinder 20 is fixed to one side of the rotating seat 25, which realizes the stable installation and angle fine adjustment function of the cylinder 20. This ensures that the cylinder 20 drives the rotating plate 5 with uniform force and smooth rotation, avoids deviation and shaking during the operation of the pneumatic mechanism, and ensures the accuracy of the flow sorting and the stability of the device operation.

[0028] An air pump 18 is fixed at the lower end of the mounting frame 1. The air pump 18 works in conjunction with the cylinder 20. A rod 24 is provided on one side of the cylinder 20. One side of the rod 24 is rotatably connected to the lower end of the rotating plate 5, providing stable power output to the cylinder 20 and realizing the telescopic drive function of the rod 24. This drives the rotating plate 5 to rotate flexibly, ensuring that the rotating plate 5 can be quickly and accurately aligned with each layer of the transfer table 6, thereby improving the response speed and smoothness of sorting and guiding.

[0029] Mounting frame 1, mounting frame 2, and transfer table 6 are fixed with brackets 16 at their lower ends. The lower end of bracket 16 is fixed with a base 15, which realizes the stable support and fixation of each component of the device, improves the overall structural integrity of the device, avoids displacement caused by vibration during device operation, ensures precise coordination of sorting, diversion, and sealing, and extends the service life of the device.

[0030] This embodiment describes the positional relationship between mounting frame 1, transfer platform 6 and mounting frame 2 10, as well as the structural basis of the pneumatic mechanism at the lower end of mounting frame 1. It also introduces the installation position of probe head 19 and the angles of the three guide frames.

[0031] Example 2 Please see Figures 3-4 As shown, this embodiment, based on embodiment 1, further includes: a controller 14 fixed at the lower end of the mounting frame 1, a motor 17 on one side of the mounting frame 1, and a conveyor belt 2 at the upper end of the mounting frame 1. The output end of the motor 17 is fixedly connected to the input end of the conveyor belt 2, thereby realizing the automatic conveying of medical items and the coordinated control function of the overall device. There is no need for manual material conveying, ensuring that the material passes through the identification area at a uniform speed and stably, ensuring the continuity of identification and sorting, and further improving work efficiency.

[0032] The mounting frame 1 has a mounting plate 4 on one side of its upper end. The mounting plate 4 has an identifier 3 on its upper end and a probe 19 on its lower end. This enables accurate identification of medical items. The probe 19 collects material information and transmits it to the identifier 3, quickly distinguishing different types of medical items. This provides an accurate basis for subsequent classification and diversion, reduces sorting errors, and improves sorting accuracy.

[0033] The flow guide frame 1 (7), flow guide frame 3 (13), and flow guide frame 2 (11) are tilted at a 15-degree angle, and one end of flow guide frame 1 (7), flow guide frame 3 (13), and flow guide frame 2 (11) is flush with one side of feed inlet 1 (9), feed inlet 2 (8), and feed inlet 3 (12). This facilitates accurate feeding and enables smooth flow and precise feeding of sorted materials. The 15-degree tilt angle ensures that the materials slide down smoothly under their own weight, avoiding material jamming and accumulation. The flush design with the feed inlet prevents material spillage, ensures feeding accuracy, and reduces material waste and pollution.

[0034] The lower end of the mounting bracket 2 10 is fixed with a fixed base 32. A rod 29 is inserted into the fixed base 32. On the opposite sides of the rods 29, movable bracket 1 27 and movable bracket 2 28 are fixed respectively, so as to realize the stable guidance and limiting function of movable bracket 1 27 and movable bracket 2 28, ensuring that the movable bracket does not deviate or jam when it moves in the center, providing stable support for the heat sealing strip 30 to accurately squeeze the plastic bag, and ensuring the stability and reliability of the sealing operation.

[0035] The movable frame 1 27 and movable frame 2 28 are equipped with racks on opposite sides. The lower end of the mounting frame 2 10 is rotatably mounted with a gear 31. The gear 31 meshes with the rack. The rotation of the gear 31 drives the movable frame 1 27 and movable frame 2 28 to move in a centered position. The movable frame 1 27 and movable frame 2 28 are equipped with heat sealing strips 30 on opposite sides. The heat sealing machine 21 is fixed to one side of the mounting frame 2 10 to realize the precise centering movement and heat sealing function of the heat sealing strip 30. Through the meshing transmission of the gear 31 and rack, the heat sealing strip 30 is driven to smoothly and evenly squeeze the plastic bag. With the help of the heat sealing machine 21, the plastic bag is quickly sealed to ensure a tight seal and prevent leakage and contamination of medical items.

[0036] The lower end of the mounting frame 210 is fixed with a fixed frame 22, and the lower end of the fixed frame 22 is fixed with a motor 23. The output end of the motor 23 is fixedly connected to the rotation center of the lower end of the gear 31, providing stable and precise power output for the rotation of the gear 31, realizing the synchronization and controllability of the centering movement of the moving frame, ensuring uniform extrusion force of the heat sealing strip 30, improving the sealing quality and efficiency of the plastic bag, and ensuring smooth connection between the sealing and sorting processes.

[0037] This embodiment describes how, after the materials are sorted, they fall into feed inlet 9, feed inlet 8, and feed inlet 12. Then, motor 23 drives gear 31 and rack to mesh, realizing the centering movement of heat sealing strip 30, sealing the top of the plastic bag, and then the material is unloaded manually or semi-automatically.

[0038] Working principle: When using this device, the medical items to be sorted can be placed on the upper end of the conveyor belt 2. Motor 17 drives the conveyor belt 2 to move, allowing the items to pass through the detector head 19 at the lower end of the identifier 3. After identification, the cylinder 20 drives the rotating plate 5 to rotate, making one end of the guide plate flush with one layer of the transfer platform 6. The material will fall onto the transfer platform 6 along the rotating plate 5, and then pass through the guide frame 1 7, guide frame 2 11, or guide frame 3 13 into the feed inlet 1 9, feed inlet 2 8, or feed inlet 3 12. The operator needs to control the flow at feed inlet 1 9, feed inlet 2 8, and feed inlet 3 12. 12. After the surface is covered with a plastic bag, the material is gradually sorted and then enters the plastic bag. Once the plastic bag is full, motor 23 drives gear 31 to rotate. Gear 31 meshes with the rack of moving frame 1 27 and moving frame 2 28, causing moving frame 1 27 and moving frame 2 28 to move in the center, so that heat sealing strip 30 squeezes and seals the plastic bag. Then, the staff takes out the sealed plastic bag, replaces it with a new plastic bag, and completes the next round of sorting and sealing collection. This device has the effect of rapid sorting, diversion and sealing of medical waste, which greatly increases the efficiency of work and has high practicality.

[0039] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. 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.
