Description

Technical Field

[0001] This invention relates to the field of plastic recycling technology, specifically to a device for recycling and processing plastic scraps used in the production of nasal irrigators. Background Technology

[0002] A nasal irrigator is a tool specifically designed to clean the nasal cavity. It works by delivering a specific liquid, such as saline solution or nasal rinse solution, into the nasal cavity. The nasal mucosa is then rinsed with water or air pressure to remove dirt, allergens, secretions, crusts, etc., thus cleaning the nasal cavity, moisturizing the mucosa, and relieving nasal discomfort. A plastic scrap recycling and processing device for nasal irrigator production is a system specifically designed to recycle and process plastic scraps generated during the production process, such as leftover plastic parts from cutting and defective molded waste, so that they can be reused as raw materials.

[0003] However, existing technologies have the following shortcomings: In existing plastic scrap recycling equipment for nasal irrigators, the automated sorting mechanism does not achieve sufficient purity in separating PP hard plastic and TPE soft plastic scraps. Due to the differences in elasticity and hardness between the two materials, it is difficult to accurately distinguish them in automated sorting, which leads to a certain degree of cross-contamination after separation. Furthermore, due to cross-contamination, the recycled material cannot be uniformly fused because of the differences in molecular structure and melting point between the two materials. Ultimately, this results in a decrease in the strength, toughness, and other properties of the recycled material, and a low resource recycling rate.

[0004] Therefore, we propose a plastic scrap recycling and processing device for nasal irrigator production to solve the problems mentioned above. Summary of the Invention

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1.

The vibrating screen initially separates PP and TPE scraps based on size differences, and the elastic baffle performs secondary screening based on the material's physical properties, allowing PP fragments to smoothly push open the spring steel baffle and enter the hard plastic channel, while TPE cannot be pushed open due to elastic deformation and enters the soft plastic channel along the inclined side.

[0017] 2. In this invention, by setting up a recycled material pretreatment component, firstly, an electric three-way valve is used to control PP and TPE fragments to enter the pretreatment chamber separately, avoiding mixing of the two materials, ensuring the purity of subsequent processing, and realizing independent and continuous pretreatment of the two materials. Secondly, an electric cylinder drives a slider to slide on a variable amplitude rod to realize dynamic adjustment of the fulcrum position. When processing PP, this dynamic adjustment uses the principle of a force-saving lever to amplify the amplitude of the fine end, generating high-intensity vibration impact, which can effectively break rigid materials. When processing TPE, the amplitude is reduced to avoid excessive crushing and material adhesion. At the same time, the strong magnetic field generated by the permanent magnet can adsorb any metal impurities that may be present in the fragments, which can prevent impurities from entering the subsequent processing stage and affecting the material properties. The magnetic field strength is matched with different fragments by steplessly adjusting the magnetic spacing. Attached Figure Description

[0020] 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.

[0021] Example 1 addresses the issue that in existing plastic scrap recycling equipment for nasal irrigators, the automated sorting mechanism does not achieve sufficient purity in separating PP hard plastic and TPE soft plastic scraps. Due to the differences in elasticity and hardness between the two materials, it is difficult to accurately distinguish them during automated sorting, which can lead to cross-contamination even after separation.

[0022] This embodiment addresses the problems of the prior art by incorporating a dual-material automatic separation and recycling component 800. Utilizing precise separation and recycling, PP and TPE scraps can be reused for injection molding or processing, avoiding material waste caused by mixed recycling and improving resource recycling efficiency. The vibrating screen initially separates PP and TPE scraps based on size differences. A secondary screening is performed using an elastic baffle 810 based on the material's physical properties, allowing PP fragments to smoothly push aside the spring steel baffle 810 and enter the first spiral inlet 818 (hard plastic channel), while TPE, due to elastic deformation, cannot be pushed aside and enters the second spiral inlet 819 (soft plastic channel) along the inclined side. This elastic baffle 810 enables automatic diversion based on the material's own physical properties.

[0023] Please see Figures 1-3 As shown, the present invention provides a technical solution: a plastic scrap recycling and processing device for nasal irrigator production, comprising a dual-material automatic separation and recycling component 800, a recycled material pretreatment component 900, and four supports 100. The dual-material automatic separation and recycling component 800 is installed on the top of the four supports 100, and the recycled material pretreatment component 900 is installed on the bottom of the four supports 100. The recycled material pretreatment component 900 is installed at the bottom of the dual-material automatic separation and recycling component 800.

[0024] Four cross braces 200 are fixedly welded between the outer walls of the four supports 100. The tops of two of the cross braces 200 are bolted together with a load-bearing plate 300. Two metal support frames 400 are fixedly connected between the outer walls of the four supports 100. The tops of the four supports 100 are respectively equipped with a control system 500, a hopper 600, and an injection assembly 700.

[0025] In use, first determine the specific installation positions of the four supports 100 and secure them firmly to the ground. After the four supports 100 are fixed, weld four cross braces 200 between the outer walls of the four supports 100 in sequence, and bolt a load-bearing plate 300 between the tops of two cross braces 200. Two metal support frames 400 are fixedly connected between the outer walls of the four supports 100. The control system 500, hopper 600, and injection assembly 700 are respectively installed on the top of the four supports 100. The dual-material automatic separation and recycling assembly 800 is installed on the top of the four supports 100, and the recycled material pretreatment assembly 900 is installed at the bottom of the four supports 100. The secure fixing of the four supports 100 provides effective support for their connected components, ensuring the stable operation of the dual-material automatic separation and recycling assembly 800 and the recycled material pretreatment assembly 900 during subsequent work. First, the control system 500 sends an injection command. The required injection material is transported through the hopper 600 to the injection assembly 700 via a pipeline. Then, the injection assembly 700 injects the material into the mold cavity at high pressure and high speed using the nozzles, thus completing the injection molding process. After the nasal irrigator is formed, the PP and TPE mixed scraps generated fall into the dual-material automatic separation and recycling assembly 800 by gravity. The dual-material automatic separation and recycling assembly 800 serves as a pre-process component of the recycled material pretreatment assembly 900. The dual-material automatic separation and recycling assembly 800 features multi-level precise separation and adaptability to material characteristics, which solves the problem of material performance degradation in traditional mixed recycling and improves the efficiency and economy of separation and recycling. Furthermore, the recycled material pretreatment assembly 900 achieves efficient and precise pretreatment of PP and PE fragments through adaptive amplitude adjustment of the high-frequency magnetic vibration crushing unit, stepless adjustment of the magnetic spacing of the permanent magnet 923 array, intelligent automatic control, and structural optimization design.

[0026] In some embodiments, according to Figures 1-8 As shown, the dual-material automatic separation and recycling component 800 includes a first screen 806, a second screen 807, and two baffles 810. The first screen 806 is used to intercept large soft plastic fragments, the second screen 807 is used to screen small hard plastic fragments, and the two baffles 810 are used to achieve automatic diversion based on elasticity differences.

[0027] The dual-material automatic separation and recycling component 800 also includes four support members 801, four limiting sleeves 814, and four vertical support frames 822. The bottom of the four support members 801 is fixedly connected to the top of the two metal support frames 400. The top of each of the four support members 801 is fixedly connected to a limiting base 802. The top of each of the four limiting bases 802 is elastically connected to a first spring 803. The top of each of the four first springs 803 is elastically connected to a fixing member 804. A frame 805 is bolted between the outer walls of the four fixing members 804. The inner wall of the frame 805 is connected to the outer walls of the first screen 806 and the second screen 807, respectively. The first screen 806 is placed on top of the second screen 807. A vibrator 808 is bolted to the bottom of the frame 805. Two first discharge ports 809 are bolted to one side of the outer wall of the frame 805.

[0028] The inner walls of the two first discharge ports 809 are respectively connected to a corresponding baffle 810 via a rotating rod. Both baffles 810 are made of spring steel. A stop rod 811 is bolted to one side of the outer wall of each of the two first discharge ports 809. A connecting sleeve 812 is fixedly fitted on the outer wall of each of the two stop rods 811. A set of second springs 813 is elastically connected to one side of the outer wall of each of the two connecting sleeves 812.

[0029] One side of the outer wall of each of the two sets of second springs 813 is elastically connected to a corresponding limiting sleeve 814. One side of the outer wall of each of the two baffles 810 is connected to one side of the outer wall of each of the two corresponding limiting sleeves 814. One end of the outer wall of each of the two first discharge ports 809 is fixedly connected to a hard material sliding plate 815. One side of the outer wall of each of the two first discharge ports 809 is provided with a second discharge port 816, and the second discharge port 816 is a soft rubber fragment discharge port. The discharge ends of the two second discharge ports 816 are connected to a soft material sliding plate 817.

[0030] A motor 823 is fixedly mounted on the top of four vertical support frames 822. The bottom of the four vertical support frames 822 is connected to the top of the load-bearing plate 300. A first spur gear is rotatably connected to the shaft end of the motor 823. A chain 824 is meshed with the outer surface of the first spur gear. A second spur gear is meshed with the inner surface of the chain 824. A first helical blade 825, which is a hard plastic helix, is rotatably connected to the rotating end of the first spur gear. A second helical blade 826, which is rotatably connected to the rotating end of the second spur gear, is also rotatably connected to the rotating end of the second spur gear. 6 is a soft rubber spiral. The outer surfaces of the first spiral blade 825 and the second spiral blade 826 are sealed and covered with a housing 820 and a tubular sealing housing 821. The bottom of the two housings 820 is fixedly connected to four metal frames. The top of the two housings 820 are respectively connected to the first spiral inlet 818 and the second spiral inlet 819. The bottom of the four metal frames is connected to the top of the load-bearing plate 300. The discharge ends of the first spiral blade 825 and the second spiral blade 826 are respectively connected to the PP hard material recycling box 827 and the TPE soft material recycling box 828.

[0031] In use, by pre-setting the above components, a complete dual-material automatic separation and recycling assembly 800 is assembled. After the nasal irrigator is formed, the mixed PP and TPE scraps fall into the dual-material automatic separation and recycling assembly 800 by gravity. The frame 805 is elastically connected to the first spring 803 via a fixing member 804. The bottom of the first spring 803 is fixed to the limiting base 802, forming an effective flexible support structure. When the vibrator 808 operates, the first spring 803 absorbs vibration energy, reducing the impact on the metal support frame 400 and lowering equipment noise. The vibrator 808 at the bottom of the frame 805 generates directional vibration, and the mixed PP and TPE scraps generated after the nasal irrigator is formed fall onto the top of the first screen 806 under the action of gravity. The upper first screen 806 utilizes the high elasticity of TPE and its tendency to agglomerate into large pieces after crushing to intercept large TPE soft plastic fragments, allowing only small PP hard plastic fragments to pass through. The lower second screen 807 can intercept small PP hard plastic fragments. The preliminarily separated material enters the next stage through the two first discharge ports 809 on one side of the frame 805. At this time, a baffle 810 made of spring steel is movably connected to the first discharge port 809 via a rotating rod, and the baffle rod 811 is fixed to the outer wall of the first discharge port 809 by bolts. The connecting sleeve 812 on its surface is connected to the second spring 813, and the other end of the spring is elastically connected to the limiting sleeve 814 on the surface of the baffle 810. By changing the corresponding position of the baffle rod 811 and different limiting sleeves 814, the second spring can be adjusted. The preload of spring 813 is used to accommodate scraps of different sizes. Due to the high rigidity and impact force of PP fragments, they are strong enough to overcome the preload of spring 813, pushing baffle 810 to open and close upwards. The fragments slide into the first spiral inlet 818 via hard material slide plate 815. Due to the high elasticity of TPE fragments, they will generate elasticity when impacting baffle 810, making it impossible to push baffle 810 open. Under the action of vibration, they slide into the second outlet 816 along the inclined surface of baffle 810, and enter the second spiral inlet 819 via soft material slide plate 817. At this time, motor 823 is started by external power supply. Motor 823 is fixed to the top of vertical support frame 822. Through the meshing transmission of the first spur gear at the shaft end, chain 824 and second spur gear, the first spiral blade 825 and the second spiral blade 826 are driven synchronously. The spiral blades 826 ensure that the conveying speeds of the two materials are matched. The first spiral blade 825 of the hard plastic spiral uses a deep groove blade made of wear-resistant cast iron with a chrome-plated surface, which can fully adapt to PP fragments and reduce conveying wear. It pushes the material from the first spiral inlet 818 to the inside of the PP hard material recycling bin 827. The second spiral blade 826 of the soft plastic spiral uses a shallow groove with a scraper design. The scraper is made of polyurethane, which can effectively clean the TPE adhesion. The material is pushed from the second spiral inlet 819 to the TPE soft material recycling bin 828 through the tubular sealing shell 821. When the PP hard material and TPE soft material are fully collected, the recycling material pretreatment component 900 is activated to pre-treat the collected PP hard material and TPE soft material.

[0032] Example 2: This example mainly addresses the issue that in existing plastic scrap recycling equipment used in nasal irrigator production, the separated PP hard plastic and TPE soft plastic scraps are cross-contaminated, causing the recycled material to fail to fuse evenly due to the differences in molecular structure and melting point between the two materials. This ultimately results in a decrease in the strength, toughness, and other properties of the recycled material, and a low resource recycling rate. This embodiment addresses the problems of the prior art by setting up a recycled material pretreatment component 900. First, an electric three-way valve 904 controls PP and TPE fragments to enter the pretreatment chamber 902 separately, preventing the two materials from mixing, ensuring the purity of subsequent processing, and achieving independent and continuous pretreatment of the two materials. Second, an electric cylinder 914 drives a slider 913 to slide on an amplitude transformer 911, achieving dynamic adjustment of the fulcrum position. When processing PP, this dynamic adjustment uses the principle of a lever to amplify the amplitude of the fine end, generating high-intensity vibration impact, which can effectively break rigid materials. When processing TPE, the amplitude is reduced to avoid over-crushing and material adhesion. At the same time, the strong magnetic field generated by the permanent magnet 923 can adsorb any metallic impurities that may be present in the fragments, preventing impurities from entering subsequent processing stages and affecting material properties. The magnetic field strength is matched to different fragments by steplessly adjusting the magnetic spacing.

[0033] In some embodiments, according to Figures 1-3 as well as Figures 9-12 As shown, the recycled material pretreatment assembly 900 includes two sets of magnetostrictive rods 908, two amplitude rods 911, two sliders 913, and a set of first electromagnetic coils 918.

[0034] The recycled material pretreatment assembly 900 also includes four metal support frames 901, two first support plates 917, and two second support plates 919. The outer walls of the four metal support frames 901 are bolted together to form a processing chamber 902. A top cover 903 is fixedly connected to the top of the processing chamber 902. A set of grooves is formed on the inner surface of the processing chamber 902, and a set of first electromagnetic coils 918 are embedded and connected between the inner surfaces of the set of grooves. An annular sleeve 924 is fixedly fitted on the outer surface of the processing chamber 902, and a set of second electromagnetic coils 925 is fixedly fitted on the outer surface of the annular sleeve 924. An electric three-way valve 904 is fixedly connected to the top of the top cover 903. The two inlet ends of the electric three-way valve 904 are respectively connected to a first pipe 905 and a second pipe 906. The inlet end of the first pipe 905 is connected to the outlet end of the PP hard material recycling box 827, and the inlet end of the second pipe 906 is connected to the outlet end of the TPE soft material recycling box 828.

[0035] The bottom of the top cover 903 is fixedly connected to two connecting parts 907. The bottom of the two connecting parts 907 is connected to the top of two sets of magnetostrictive rods 908. The bottom of each set of magnetostrictive rods 908 is threadedly connected to a metal connecting plate 909. The bottom of each metal connecting plate 909 is fixedly connected to a metal block 910. One side of the outer wall of each metal block 910 is threadedly connected to a corresponding amplitude rod 911. The outer surface of each amplitude rod 911 is fixedly fitted with a vibration support block 912.

[0036] The bottom of each of the two vibrating blocks 912 is connected to the top of one of the first support plates 917. The tops of the two first support plates 917 are bolted together with two base plates 916. The two ends of the outer walls of the two first support plates 917 are bolted to the inner surface of the processing chamber 902. An electric cylinder 914 is bolted to one end of the outer wall of each of the two base plates 916. An L-shaped plate 915 is fixedly sleeved on the shaft end of each of the two electric cylinders 914. One side of the outer wall of each of the two L-shaped plates 915 is bolted to one side of the outer wall of a corresponding slider 913. The two sliders 913 are movably sleeved on the outer surface of the two amplitude rods 911.

[0037] The outer ends of the two second support plates 919 are bolted to the inner surface of the processing cavity 902. The top of each of the two second support plates 919 is provided with a sliding groove. The inner surface of each of the two sliding grooves is slidably connected to two slide blocks 920. The bottom of each of the two second support plates 919 is bolted to a metal connector 921. The top of each of the two metal connectors 921 is fixedly installed with an electric push rod 922. The shaft end of each of the two electric push rods 922 is bolted to an arc frame 926. The bottom of each of the two arc frames 926 is connected to the top of one of the slide blocks 920. The inner surface of each of the two arc frames 926 is embedded with a set of permanent magnets 923.

[0038] In use, the above components form a complete recycled material pretreatment component 900. After being conveyed and separated by the upstream dual-material automatic separation and recycling component 800, the PP and TPE fragments enter the electric three-way valve 904 through the corresponding first pipe 905 and second pipe 906. The electric three-way valve 904 automatically switches channels according to the material type, controlling the materials to enter the processing chamber 902 separately, achieving independent pretreatment of hard plastics and soft plastics, avoiding mixed contamination of the two materials during the pretreatment stage. Two sets of magnetostrictive rods 908 are fixed to the bottom of the top cover 903 by the connecting piece 907. After the external first electromagnetic coil 918 is energized, the magnetostrictive rods 908 generate axial high-frequency micro-vibrations based on the magnetostrictive effect, which are transmitted through the metal connecting disc 9. 09. The metal block 910 transmits vibration to the amplitude transformer 911. The amplitude transformer 911, with its gradually changing diameter from the thick end to the thin end, utilizes the mechanical lever principle to amplify the micro-vibration of the magnetostrictive rod 908 to an effective crushing amplitude. The vibration support block 912 is fixedly sleeved in the middle of the amplitude transformer 911, and the bottom is connected to the first support plate 917, which stably transmits the vibration energy to the processing chamber 902, while absorbing lateral redundant vibration and ensuring energy concentration. The electric cylinder 914 on the base plate 916 drives the slider 913 to slide along the amplitude transformer 911 through the L-shaped plate 915. When it is necessary to pre-process the PP hard plastic fragments for crushing, the electric cylinder 914 drives the slider 913 to move towards the thick end of the amplitude transformer 911 through the L-shaped plate 915, forming a force-saving lever, which amplifies the amplitude at the thin end. This generates high-intensity vibration and impact, adapting to the high rigidity of PP hard plastic fragments. When pretreatment of TPE soft material is required, the slider 913 moves towards the narrow end of the amplitude rod 911, forming a lever that requires more effort. The amplitude at the narrow end will be reduced, which can prevent the TPE soft material from sticking together due to excessive crushing. Subsequently, the permanent magnet 923 embedded in the inner surface of the arc frame 926 generates a strong magnetic field to adsorb metal impurities mixed in the material. The metal connector 921 at the bottom of the second support plate 919 fixes the electric push rod 922. The shaft end of the electric push rod 922 is connected to the arc frame 926. The bottom of the arc frame 926 is slidably connected to the slide groove of the second support plate 919 through the slide seat 920. The electric push rod 922 drives the arc frame 926 to move along the slide groove, realizing the spacing between the permanent magnets 923 on both sides. The stepless adjustment of the magnetic field distribution of the second electromagnetic coil 925, coupled with the magnetic field distribution of the permanent magnet 923, can change the magnetic field gradient distribution within the processing chamber 902. The crushed material passes through the magnetic field area under the action of gravity and vibration. Metal impurities are adsorbed and retained by the permanent magnet 923, while the pure material continues to fall into the subsequent conveying stage. When processing large PP fragments that are not completely crushed, the electric push rod 922 drives the arc frame 926 to move outward, increasing the magnetic spacing and expanding the magnetic field coverage to ensure that impurities in the large fragments can enter the magnetic field area. When processing small TPE fragments, the electric push rod 922 drives the arc frame 926 to move inward, reducing the magnetic spacing and enhancing the local magnetic field gradient to improve the adsorption capacity for small impurities.

[0039] In a more specific embodiment, the final result of combining the dual-material automatic separation and recycling component 800 described in Example 1 and the recycled material pretreatment component 900 described in Example 2 is as follows: The dual-material automatic separation and recycling component 800, through the synergistic action of the elastic baffle 810 and the first spiral blade 825 and the second spiral blade 826, sends PP fragments through the first spiral inlet 818 into the PP hard material recycling bin 827, and TPE fragments through the second spiral inlet 819 into the TPE soft material recycling bin 828, achieving physical isolation and storage of the two materials. The electric three-way valve 904 of the recycled material pretreatment component 900 is precisely connected to the upstream PP hard material recycling bin 827 and TPE soft material recycling bin 828, receiving PP fragments and TPE fragments respectively through pipelines. E-fragments automatically switch channels according to material type, controlling materials to enter the processing chamber 902 separately to ensure no mixing throughout the process. At the same time, the control system 500 receives material type sensor signals from the dual-material automatic separation and recycling component 800 and synchronously sends parameter instructions to the recycling pretreatment component 900. When PP material is detected, large-amplitude crushing and wide magnetic spacing adsorption are triggered. When TPE material is detected, it switches to small-amplitude crushing and narrow magnetic spacing adsorption, realizing seamless connection between the dual-material automatic separation and recycling component 800 and the recycling pretreatment component 900.
