Description

Technical Field

[0001] The present invention relates to the technical field of needle recycling, and particularly to a waste needle recycling device for needle production. Background Art

[0002] With the rapid development of the medical industry, the generation of medical waste needles has increased sharply, which contains a large number of potentially harmful substances, such as pathogenic microorganisms, chemical drug residues, and radioactive waste, etc. Therefore, setting up an efficient and safe waste medical recycling device has become an urgent need;

[0003] Medical waste contains a large number of pathogens and chemical pollutants, and needs to be harmlessly treated through professional equipment to reduce environmental pollution, prevent the spread of pathogens in medical waste, and protect the health and safety of medical staff and the public.

[0004] Medical institutions must be equipped with qualified waste medical recycling devices to ensure that the waste is properly treated. The disadvantages of current waste medical recycling devices are as follows:

[0005] 1. Unreasonable device design: Some existing recycling devices have simple designs and lack effective sealing and isolation measures, which are likely to cause waste leakage and cross-infection.

[0006] 2. Low degree of automation: Many recycling devices rely on manual operation, with low efficiency and safety risks.

[0007] 3. Insufficient intelligent level: Lack of real-time monitoring and data analysis functions, making it difficult to effectively supervise and optimize the recycling process.

[0008] 4. High cost: Although some high-end recycling devices have excellent performance, they are expensive and difficult to popularize in small and medium-sized medical institutions.

[0009] The setting of waste medical recycling devices is of great significance for ensuring public health safety and promoting environmental protection. However, there are still many disadvantages in the current devices in terms of design, automation, intelligence, and cost. Therefore, in the future, more research and development efforts should be made to promote the technological innovation and upgrading of recycling devices and improve the performance and practicability of the devices.

[0045] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0046] Please refer to Figures 1-12 , the present invention provides a technical solution: a waste needle recycling device for needle production, including a recycling barrel 1. A needle transportation mechanism 2, a needle storage mechanism 3, and a recycling mechanism 4 are arranged in the recycling barrel 1. The entire recycling device is configured with an equipment system, and the entire recycling device is driven to operate through the equipment system;

[0047] The equipment is configured with a power source, and the power source is a rechargeable battery;

[0048] The needle transportation mechanism 2 is used to transport the needles that have not been cured and processed to the needle storage mechanism 3 for the curing process by the needle storage mechanism 3, and transport the needles that have been cured and processed into the recycling mechanism 4 after the needle storage mechanism 3 completes the curing process of the needles;

[0049] The needle storage mechanism 3 is used to cure and process the needles thrown into the recycling barrel 1;

[0050] The recycling mechanism 4 includes two first storage boxes 41 and a second storage box 42 for storing the needles that have been cured and processed;

[0051] A needle inlet hole 11 is provided at the top of the recycling barrel 1. The needles are manually thrown into the needle inlet hole 11, and the needles enter the needle transportation mechanism 2 through the needle inlet hole 11;

[0052] The needle transportation mechanism 2 includes a thick metal plate 21, and a fixing groove 22 is provided at each of the four corners of the thick metal plate 21. A clamping rod made of plastic, which is detachably fixed to the inner bottom of the recycling barrel 1 and reduces the overall weight of the recycling barrel 1, is arranged in the fixing groove 22. The needle transportation mechanism 2 further includes a short rod 23, two long rods 24, and a main rod 25. The two long rods 24 and a main rod 25 are fixed to the inner bottom of the recycling barrel 1, and the short rod 23 is fixed to the top of the thick metal plate 21. The top surfaces of a short rod 23, two long rods 24, and a main rod 25 are on the same horizontal plane. A track base plate 26 is fixedly installed in the upper region surrounding a short rod 23, two long rods 24, and a main rod 25. The track base plate 26, a short rod 23, two long rods 24, and a main rod 25 form a path for needle transportation;

[0053] A plurality of conveying holes 261 for the needle to enter are provided on the track base plate 26. A track 262 is provided at the bottom of the track base plate 26. A clamping block 263 is slidably connected to the track 262. A clamping hole 264 is provided on each clamping block 263. The specification of each clamping hole 264 matches that of the conveying hole 261. When the clamping block 263 moves along the track 262 to the lower side of the conveying hole 261, the clamping hole 264 can receive the needle in the conveying hole 261;

[0054] First vertical rails 2611 are fixedly installed on the inner side walls on both sides of the conveying hole 261. First sliding braces 2612 are slidably connected to each first vertical rail 2611. Two telescopic rods 2613 are fixedly installed on the outer side wall of each first sliding brace 2612. The telescopic rod 2613 is a prior art structure, and its function is to drive the telescopic rod 2613 to perform telescopic movement through a built-in energy supply mechanism. The first sliding brace 2612 is driven by the equipment system to move up and down along the first vertical rail 2611, and the telescopic rod 2613 is driven by the equipment system to operate. When the needle enters the conveying hole 261 from top to bottom, at this time, the telescopic rod 2613 is at the uppermost end of the first vertical rail 2611 along with the first sliding brace 2612, so that the time for the needle to enter the conveying hole 261 is the shortest. If the distance from the needle entry hole 11 to the conveying hole 261 is too long, the probability of the needle generating a position deviation during the descent process will increase. The pressure sensor 2614 provided at the top of the telescopic rod 2613 is used to judge whether there is a needle in the conveying hole 261, and it is necessary that all the pressure sensors 2614 on the telescopic rods 2613 on both sides detect data before it is determined that there is a needle in the conveying hole 261. A needle descent channel is provided between the needle entry hole 11 and the conveying hole 261, and the shape of the channel matches the shape of the needle shank of the needle. The aperture of the conveying hole 261 is larger than the aperture of the needle descent channel. Therefore, the telescopic rod 2613 is pre-run to the uppermost end of the first vertical rail 2611 to ensure that the needle directly falls onto the top of the telescopic rod 2613 through the needle shank descent channel of the needle. First, the movement track of the needle is more stable, and second, the detection stability of the pressure sensor 2614 is higher;

[0055] On the inner side walls of both sides of the clamping hole 264, the second vertical rails 2631 are fixedly installed. A second sliding support 2632 is slidably connected to each second vertical rail 2631. An electric control rotating rod 2633 is arranged on the outer side wall of each second sliding support 2632. An inclined rod 2634 is fixedly installed on each electric control rotating rod 2633. A flat plate 2635 is fixedly installed at the end of each inclined rod 2634. A rubber layer is arranged on the surface of each flat plate 2635. The equipment system controls the second sliding support 2632 to move up and down along the second sliding support 2632. When the pressure sensor 2614 detects that the needle bolt has been successfully positioned, the equipment system controls the second sliding support 2632 to rise along the second sliding support 2632. When the second sliding support 2632 does not move, the distance between the tops of the two electric control rotating rods 2633 is the largest, which is convenient for the needle to fall. When the second sliding support 2632 rises to the topmost end of the flat plate 2635, the equipment system first drives the two electric control rotating rods 2633 to operate to reduce the distance between the two electric control rotating rods 2633, that is, the electric control rotating rod 2633 drives the flat plate 2635 to move towards the needle until the needle is clamped. Here, the telescopic rod 2613 still serves as the structure for supporting the needle bolt and does not operate. The equipment system drives the second sliding support 2632 to descend to the bottom end along the second vertical rail 2631, driving the electric control rotating rod 2633 to descend, driving the inclined rod 2634 to descend, and driving the flat plate 2635 to descend. At this time, due to the support of the telescopic rod 2613, when the flat plate 2635 descends, the rubber layer also descends, and the impurities and moisture on the outer surface of the needle are scraped off by the rubber layer. If the impurity removal is not carried out, during the subsequent movement of the needle, the liquid will cover the movement path of the needle, and the presence of impurities during the curing process of the needle will result in low quality of the needle curing result. Then the equipment system drives the electric control rotating rod 2633 to operate to increase the distance between the two flat plates 2635, and then resets to the state where the two flat plates 2635 clamp the needle. At this time, the equipment system drives the telescopic rod 2613 to contract until the telescopic rod 2613 no longer supports the needle bolt. Then the equipment system drives the second sliding support 2632 to descend to the bottom end along the second vertical rail 2631. At this time, the entire needle bolt is located in the clamping hole 264, and the needle at this time is fixed in the clamping hole 264 and can move on the track 262;

[0056] The needle storage mechanism 3 includes a first motor 31 and a second motor 32 fixedly installed on the top of the thick plate metal block 21. A first reel 33 is fixedly installed on the output end of the first motor 31, and a second reel 34 is fixedly installed on the output end of the second motor 32. A winding film is wound on the first reel 33, and an adhesive layer is coated on the winding film. The adhesive layer is in a solid state at normal temperature. A first limiting rod 35, a second limiting rod 36, a third limiting rod 37, a fourth limiting rod 38, and a fifth limiting rod 39 are respectively arranged on the path where the winding film on the first reel 33 moves to the second reel 34. The first limiting rod 35, the second limiting rod 36, the third limiting rod 37, the fourth limiting rod 38, and the fifth limiting rod 39 are all arranged on the top of the thick plate metal block 21 through a bearing shaft 51, so that the first limiting rod 35, the second limiting rod 36, the third limiting rod 37, the fourth limiting rod 38, and the fifth limiting rod 39 can all rotate through the bearing shaft 51. An operator winds the winding film on the first reel 33 around the first limiting rod 35 and the second limiting rod 36. A hot air blower 52 is arranged on one side of the first limiting rod 35 and the second limiting rod 36. The function of the hot air blower 52 is to spray out the gas after heating, and its hot air is sprayed towards the winding film. The function of the hot air blower 52 here is to melt the adhesive layer that has just moved out of the first reel 33. The melted adhesive layer has an adhesive function. After the winding film moves out through the first limiting rod 35 and the second limiting rod 36, it then moves out through the third limiting rod 37 and the fourth limiting rod 38. Through the limitation of the three limiting rods of the second limiting rod 36, the third limiting rod 37, and the fourth limiting rod 38, the winding film forms a quasi-rectangular channel, and the needle part is located in this quasi-rectangular channel. Finally, it is wound on the second reel 34 through the fifth limiting rod 39 to complete the entire movement process of the winding film;

[0057] On both sides of the quasi-rectangular channel, a set of solidification components 6 are respectively arranged. Each set of solidification components 6 includes a bottom rail 61 fixed on the top of the thick plate metal block 21. A power supply chassis 62 is slidably connected to the bottom rail 61. A condensation plate 63 is arranged on the side wall of the power supply chassis 62. The width of the condensation plate 63 is the same as that of the power supply chassis 62, but only the middle area part of it generates functions, which is sufficient to completely cover the processing area of the needle. After the needle enters the quasi-rectangular channel, the equipment system drives the two power supply chassis 62 to move towards each other along the bottom rail 61. By driving the movement of the power supply chassis 62, the condensation plate 63 is driven to move. The two condensation plates 63 press the film rolls on both sides of the quasi-rectangular channel. The film rolls on both sides are pressed to move and surround the needle until the two condensation plates 63 stop moving. Then the condensation plate 63 starts to condense the glue layer surrounding the needle, so that the glue layer within the processing area of the condensation plate 63 is separated from the film roll and adheres to the needle, forming a protective layer on the needle. The condensation duration of the condensation plate 63 is set in the equipment system. When the condensation duration of the condensation plate 63 is reached, the equipment system drives the power supply chassis 62 to reset along the bottom rail 61, driving the condensation plate 63 to reset. Then, the needle with the protective layer formed is transported to the shaping component 7 arranged on the side of the needle transport mechanism 2 by the needle transport mechanism 2;

[0058] The condensation plate 63 is a prior art structure and will not be elaborated here. Its function is low-temperature shaping;

[0059] The distance between the hot air blower 52 and the film roll is very short, so the power of the hot air blower 52 is low, and the heat energy generated in the recycling bin 1 is not sufficient to act on the glue layer in the remaining areas;

[0060] The shaping component 7 includes several glue storage boxes 71 detachably and fixedly installed on the top of the recycling bin 1, and a central box 72 arranged inside the recycling bin 1. The glue storage boxes 71 and the central box 72 are connected by pipelines, and an intelligent pump is set. The glue is transported from the glue storage boxes 71 to the central box 72 as needed through the intelligent pump. The shaping component 7 also includes a support plate 73 fixed on the side of the thick metal block 21. A shaping chamber 74 is arranged inside the support plate 73. Several liquid outlet holes 75 are arranged on the side wall of the shaping chamber 74. The liquid outlet holes 75 and the central box 72 are connected by pipelines. A one-way pump valve is arranged on the pipeline between the liquid outlet holes 75 and the central box 72, so that the glue entering the shaping chamber 74 will not flow back. After the needle enters the recycling bin 1 through the needle entry hole 11, it will first move to the quasi-rectangular channel through the needle transportation mechanism 2. At this time, the equipment system drives the second sliding support 2632 to descend along the second vertical rail 2631 to drive the clamped and fixed needle to descend until the tip of the needle enters the quasi-rectangular channel for protective layer shaping. Then it resets to the movable height, and moves the needle that has completed the protective layer shaping to above the shaping chamber 74. The equipment system drives the second sliding support 2632 to descend along the second vertical rail 2631 again to drive the clamped and fixed needle to descend until the needle enters the shaping chamber 74. At this time, the equipment system drives the intelligent pump to operate. The glue in the glue storage boxes 71 is transported to the central box 72 through the intelligent pump, and then enters the shaping chamber 74 through the central box 72 and the liquid outlet holes 75. The infusion volume of the intelligent pump each time is a preset quantity, and a whole piece of glue block can be solidified on the surface layer of the needle. The function of this glue block is to process a piece of glue block at the tip of the needle, and ensure that the needle will not cause secondary injury through the glue block. Forming a protective layer in the quasi-rectangular channel before this process is because the viscosity of the protective layer ensures that the glue block will not fall off the needle;

[0061] A refrigerator 76 is arranged at the bottom of the shaping chamber 74. The refrigerator 76 is controlled by the equipment system to condense the glue in the shaping chamber 74, causing the glue to form blocks;

[0062] As the needle transportation mechanism 2 drives the needle that has completed the glue block curing process to above the first storage box 41 and the second storage box 42, the equipment system drives the electric control rotating rod 2633 to rotate to loosen the needle, so that it falls into the first storage box 41 and the second storage box 42. The first storage box 41 and the second storage box 42 store the needles alternately;

[0063] Multiple needles can be stored from top to bottom in the needle descending channel. When the bottommost needle in the needle descending channel enters the clamping hole 264, the two telescopic rods 2613 are immediately reset to clamp the previous needle, so that each needle moves and is processed in an orderly manner.
