Hereinafter, the present invention will be described in detail with reference to the drawings and in combination with the embodiments.

[0052] Refer to Figure 1-2 As shown, in some embodiments of the present application, the present embodiment provides a disposable plastic bag converter, including:

[0053] A converter housing 100, with an accommodating cavity 210 provided on one side inside;

[0054] A feeding assembly, provided above the accommodating cavity 210, and the feeding assembly is used to put the plastic bags to be processed into the inside of the converter housing 100;

[0055] The cutting assembly includes a heating wire cutter 121 disposed on one side of the feeding assembly for cutting the plastic bag to be processed into strip-shaped plastic bags, and a second transmission wheel connected to the feeding assembly is provided at the end of the heating wire cutter 121. The cutting assembly further includes a cutter set located in the middle of the accommodating cavity 210 for cutting the strip-shaped plastic bags into fragment-shaped plastic bags;

[0056] The conveying assembly and the funnel 180 are provided at the bottom of the accommodating cavity 210 and below the cutting assembly. The funnel 180 is detachably connected to the discharge end of the conveying assembly, and the conveying assembly is used to convey the fragment-shaped plastic bags into the funnel 180;

[0057] The hot melting assembly is disposed inside the converter housing 100 and below the conveying assembly. The outlet of the funnel 180 is directly above the inlet of the hot melting assembly, and the hot melting assembly is used to hot melt the fragment-shaped plastic bags into recycled plastic particles;

[0058] The cooling assembly is provided at the outlet of the hot melting assembly, and the cooling assembly is used to cool the recycled plastic particles;

[0059] The collection box 170 is disposed inside the converter housing 100 and below the cooling assembly;

[0060] The exhaust gas filtering assembly is disposed inside the converter housing 100, and the exhaust gas filtering assembly is used to filter the exhaust gas inside the converter housing 100.

[0061] In this embodiment, the heating wire cutter 121 is the annular multi-channel conductive module type heating wire cutter 121 in the patent with the patent number CN202410042594.6.

[0062] In this embodiment, the cooling assembly cools by using a refrigeration chip to generate cold air.

[0063] In this embodiment, the exhaust gas filtering assembly is composed of three suction pipelines and one filtering pipeline. Specifically, the first suction pipeline is located above the heating wire cutter 121, that is, at the top of the machine; the second one is located above the outlet of the funnel 180; the third one preferably extends into the cooling cavity 161 or can be arranged near the cooling cavity 161. These three suction pipelines are responsible for sucking in the exhaust gas and, with the help of the vacuum pump 190, discharging the purified exhaust gas from the air outlet. The air outlet is connected to a filtering device 200 composed of a triple filter. The first process is sponge filtration (sponge filtration layer) to filter out the dust in the exhaust gas; the second filtration is carried out by a self-developed carbon adsorption material. The self-developed carbon adsorption material is made from water, carbon powder, sand, and glutinous rice in a ratio of (1:1:1:0.2) (carbon adsorption material filtration layer). The second filtration is extremely important and affects the environmental protection index of this machine. It plays a very important role in ensuring that no harmful gases are emitted after using the machine; the third filtration is composed of a carbon cake and a cotton sheet (carbon cotton filtration layer). The gas discharged through the three-stage filtration is required to be harmless, odorless, and non-toxic air.

[0064] In this embodiment, the size of the converter housing 100 is 425 mm in length, 350 mm in height, and 150 mm in thickness. The converter housing 100 is made of high-quality flame-retardant reinforced ABS material, ensuring its structural firmness and environmental protection characteristics.

[0065] In this embodiment, a circular power button is configured in the upper left corner of the converter housing 100, and five indicator lights are arranged adjacent to it, which are white, yellow, blue, red, and green in sequence. The white indicator light represents that the power is on; the yellow indicator light lights up and starts to flash when the heating wire is broken to indicate a fault alarm; the blue indicator light lights up meaning that the collection box 170 is not reset; the red indicator light lights up indicating that the over-thick plastic material blocks the bag inlet, causing the counter-roll of the bag inlet; the green indicator light is a full bin indicator and will light up when a box of plastic particles is fully collected.

[0066] In this embodiment, directly below the power button and the five indicator lights is a 7-inch liquid crystal touch screen. Teaching videos will be shown on the screen to guide users on how to correctly use this converter housing 100 and encourage everyone to use the converter housing 100 to participate in environmental protection and reduce the pollution of plastic waste to the environment. The video content aims to spread the harm of plastic waste and the damage it causes to the environment and actively promote positive information; a speaker is equipped below the screen to ensure that the sound in the video can be clearly played, enhancing the audio-visual experience.

[0067] In this embodiment, a large collection box 170 is arranged below the conversion machine housing 100, and the collection box 170 is taken out or reset through a pressing and rebounding mechanism. This collection box 170 is specifically used for collecting plastic particles to be recycled. If the collection box 170 is not properly installed, the blue indicator light will turn on to give a reminder. When the collection box 170 is full and needs to be replaced with an empty one, the green indicator light will turn on to prompt the user to replace it.

[0068] In this embodiment, the power connection plug is arranged in the lower left area of the outer shell of the conversion machine housing 100. The power socket is equipped with an overvoltage protection device, which will automatically cut off the power once the voltage abnormally rises, ensuring that the conversion machine housing 100 is not damaged and preventing potential safety risks. The heat dissipation port above the left power interface is designed specifically for cooling the components. The back of the conversion machine housing 100, that is, the rear cover part, adopts a sunken snap-fit design, which not only enhances the fit with the wall but also maintains aesthetics, while not hindering the heat dissipation of the housing back. In addition, a ventilation and heat dissipation port is also provided on the rear cover of the conversion machine housing 100 to promote heat dissipation.

[0069] In this embodiment, the disposable plastic bag conversion machine is equipped with a control system composed of an Android development board, a circuit control board, and a power board. The entire working process is as follows: First, the Android development board is installed on the top right side of the conversion machine housing 100, responsible for controlling the content played on the screen and the sound output. The development board integrates a Wi-Fi module and an antenna, facilitating connection to the home network. Its operating memory is 2GB, and the storage space is 8GB, supporting background video content transmission and software version updates. The circuit control board is installed in the upper part of the right side facade of the conversion machine housing 100, which is responsible for connecting internal electronic induction switches, motors, fans, safety fall switches (to ensure safe use, this conversion machine housing 100 can only be used when placed correctly and cannot be used in cases such as tilting, inversion, lying flat, or side placement), power switches, heating wire interfaces (for connecting the heating wire cutter 121), power interfaces, refrigeration chip interfaces, temperature control interfaces, full bin interfaces, collection box 170 reset interfaces, and output and input interfaces for the 12V power supply, etc.; the Android development board is responsible for screen control, while the circuit control board is responsible for the operation of the entire conversion machine housing 100; in the lower part of the right side facade, a high-current power board is installed, which can convert the input current of 220V into an output current of 12V to supply power to the circuit control board and the Android development board. In addition, the power board also provides 220V power support for the heating device to ensure that the heating device can generate heat normally.

[0070] It can be understood that the disposable plastic bag converter provided in this embodiment can quickly and efficiently convert disposable plastic bags into recyclable plastic particles, which not only solves the environmental protection problem of difficult degradation of plastic waste but also realizes the recycling of resources. Through the precise cutting of the cutting component, the plastic bag can be cut into pieces, facilitating the subsequent hot melting process. The hot melting component uses advanced heating elements to quickly melt the shredded plastic bags into granular form, and the quality of the granules is stable, making it easy for subsequent processing and utilization. The cooling component ensures that the hot-melted plastic particles can be quickly cooled and solidified, facilitating collection and storage. At the same time, the setting of the waste gas filtration component effectively avoids environmental pollution caused by waste gas generated during the conversion process, further enhancing the environmental protection performance of the converter. In addition, the converter also has the advantages of simple operation, safety and reliability, and convenient maintenance, providing a new solution for the recycling of plastic waste.

[0071] Specifically, the feeding component includes:

[0072] A bag inlet, opened on one side of the converter housing 100;

[0073] Bag inlet counter-rollers, arranged inside the converter housing 100. The bag inlet counter-rollers include a driving splined roller 111 and a rubber roller respectively arranged at the upper and lower parts corresponding to the bag inlet. A first gear 114 is arranged at the end of the driving splined roller 111, and a first driving wheel 113 connected to a second driving wheel through a first belt is also arranged at the end of the driving splined roller 111. A second gear 115 meshing with the first gear 114 is arranged at the end of the rubber roller.

[0074] In the embodiment, both ends of the bag inlet counter-rollers are fixed inside the fixing frame 112, and two small springs are respectively arranged between both ends of the driving splined roller 111 and the fixing frame 112 for pressing the bag inlet counter-rollers.

[0075] It can be understood that the combined design of the driving splined roller 111 and the rubber roller not only realizes the stable feeding of the plastic bag but also effectively discharges the residual liquid in the plastic bag through the extrusion action, avoiding the interference of the liquid on subsequent processing steps. The setting of the bag inlet counter-rollers not only ensures that the plastic bag can smoothly enter the inside of the converter housing 100 but also effectively separates and processes the liquid in the plastic bag through a reasonable structural design, improving the practicability and processing efficiency of the entire system. In addition, the connection between the first driving wheel 113 and the second driving wheel through the first belt realizes the linkage between the feeding component and the cutting component, ensuring the timely and accurate progress of the cutting step.

[0076] Specifically, the conveying component includes:

[0077] The driving roller 131, the driven roller 132 and the transmission belt. The driving roller 131 and the driven roller 132 are connected by the transmission belt. One end of the driving roller 131 extends out of the accommodating cavity 210 and is provided with a first helical gear. The end of the transmission belt away from the driving roller 131 is detachably connected to the funnel 180.

[0078] It can be understood that through the cooperation of the driving roller 131, the driven roller 132 and the transmission belt, the conveying assembly realizes the stable conveyance of the fragmented plastic bags, ensuring the continuity and high efficiency of subsequent processing.

[0079] Specifically, the disposable plastic bag converter further includes:

[0080] The first connecting plate 140 is arranged outside the accommodating cavity 210 and at one end of the bottom of the accommodating cavity 210 close to the first helical gear. The first connecting plate 140 is provided with a through hole for the rotation shaft to extend out in the horizontal direction. One end of the rotation shaft is connected with a third transmission wheel connected to the cutting assembly, and the other end of the rotation shaft is provided with a second helical gear meshing with the first helical gear.

[0081] Specifically, the cutting knife group includes:

[0082] The first blade shaft 122 is arranged horizontally in the middle of the accommodating cavity 210. One end of the first blade shaft 122 is rotatably connected to the accommodating cavity 210, and the other end of the first blade shaft 122 extends out of the accommodating cavity 210 and is connected to the first motor 125.

[0083] The second blade shaft 123 is arranged horizontally on the side of the first blade shaft 122 away from the inner side wall of the converter housing 100. The end of the second blade shaft 123 extends out of the accommodating cavity 210, and a fourth transmission wheel is arranged at the end of the second blade shaft 123. Among them, the fourth transmission wheel near the first motor 125 is connected to the second transmission wheel near the first motor 125 through the second belt, and the fourth transmission wheel away from the first motor 125 is connected to the third transmission wheel away from the first motor 125 through the third belt.

[0084] The blade group 124 has two groups. The two groups of blade groups 124 are respectively sleeved outside the first blade shaft 122 and the second blade shaft 123, and the two groups of blade groups 124 are arranged staggeredly.

[0085] In this embodiment, the number of blades in each blade group 124 is preferably 12.

[0086] It can be understood that the first blade shaft 122 is driven by the first motor 125, and then drives the second blade shaft 123 connected thereto to rotate synchronously. Under the action of the staggered arrangement of the two groups of blade sets 124, the passing strip-shaped plastic bag is cut efficiently and evenly. During the cutting process, the plastic bag is stably clamped between the first blade shaft 122 and the second blade shaft 123, ensuring the accuracy and stability of the cutting.

[0087] It can be understood that a fourth transmission wheel is provided at the end of the second blade shaft 123. When the second blade shaft 123 rotates, the fourth transmission wheel rotates accordingly, and is respectively connected to the second transmission wheel and the third transmission wheel through the second belt and the third belt for transmission connection. And when the fourth transmission wheel rotates, it will also drive the third transmission wheel to rotate. The third transmission wheel drives the rotating shaft to rotate, and then the second helical gear meshes with the first helical gear, realizing the synchronous operation of the conveying assembly. This not only ensures the close cooperation between the cutting step and the conveying step, but also improves the operating efficiency and stability of the entire system.

[0088] Specifically, the hot melt assembly includes;

[0089] The hot melt cavity 151 is arranged horizontally below the conveyor belt. An inlet is provided on one side of the hot melt cavity 151 close to the first motor 125, and the inlet is directly below the outlet of the funnel 180;

[0090] The screw conveyor 152 is arranged horizontally inside the hot melt cavity 151. A cutting knife is provided at one end of the screw conveyor 152, and the other end of the screw conveyor 152 is connected to the second motor 154;

[0091] The hot melt area 153 is sleeved on the outer middle part of the hot melt cavity 151. Heating elements for melting the fragmented plastic bags into recyclable plastic particles are arranged inside the hot melt area 153.

[0092] It can be understood that the fragmented plastic bags fall into the inlet of the hot melt cavity 151 through the outlet of the funnel 180, and then are steadily pushed forward by the screw conveyor 152. The cutting knife on the screw conveyor 152 further cuts the fragmented plastic bags into smaller pieces during the pushing process to ensure better hot melt effect. These pieces are heated by the heating elements in the hot melt cavity 151, gradually softened and fused with each other, and finally form continuous recyclable plastic particles. The design of the hot melt area 153 makes the heating more uniform, ensuring the quality and consistency of the plastic particles.

[0093] Specifically, the cooling assembly includes:

[0094] The cooling cavity 161 is located on the side of the hot melt assembly away from the funnel 180;

[0095] The Peltier element is arranged on the side of the cooling cavity 161 away from the hot-melt component, and the side of the Peltier element close to the hot-melt component is the cooling surface, while the side of the Peltier element away from the hot-melt component is the heat dissipation surface;

[0096] There are three cooling fans, which are respectively arranged on the inner top wall of the cooling cavity 161, on the side of the cooling surface close to the hot-melt component, and on the side of the heat dissipation surface away from the hot-melt component.

[0097] It can be understood that after the plastic particles to be recycled are discharged from the hot-melt cavity 151, they enter the cooling cavity 161. Inside the cooling cavity 161, the side of the Peltier element close to the hot-melt component releases cold, quickly cooling the plastic particles to be recycled. At the same time, the three cooling fans blow air on the cooling cavity 161, the cooling surface and the heat dissipation surface from different angles respectively, accelerating the heat dissipation and ensuring that the plastic particles can be quickly solidified. This design not only improves the cooling efficiency but also ensures the uniformity of cooling, making the finally obtained plastic particles regular in shape and easy for subsequent collection and processing.

[0098] Specifically, the waste gas filtering component includes:

[0099] The first suction pipeline, one end of which is arranged above the heating wire cutter 121;

[0100] The second suction pipeline, one end of which is arranged above the outlet of the funnel 180;

[0101] The third suction pipeline, one end of which extends into the interior of the cooling cavity 161;

[0102] The vacuum pump 190, and the other ends of the first suction pipeline, the second suction pipeline and the third suction pipeline are all connected to the air inlet of the vacuum pump 190;

[0103] The filtering device 200 is arranged at the air outlet of the vacuum pump 190;

[0104] The third motor is located inside the conversion machine housing 100, and the output end of the third motor is connected to the vacuum pump 190.

[0105] Specifically, the filtering device 200 includes a sponge filtering layer, a carbon adsorption material filtering layer and a carbon cotton filtering layer arranged in sequence from the air inlet to the air outlet direction;

[0106] Among them, the carbon adsorption material filtering layer is made of water, carbon powder, sandy soil and glutinous rice with a weight ratio of 1:1:1:0.2; the carbon cotton filtering layer is composed of a carbon cake and a cotton sheet.

[0107] In this embodiment, the method for preparing the carbon adsorption material filter layer is as follows: First, stir the steamed glutinous rice, then add clear water in batches and continue stirring until the water and the glutinous rice dough are fully and evenly mixed. Next, pour the mixture into the pre-prepared mixture of carbon powder and sand, and stir until it forms a dough. After that, use a mold to press it into a honeycomb shape suitable for a specific use scenario, and perform demolding and drying treatments, and then it can be put into use.

[0108] It can be understood that during the working process of the conversion machine, certain waste gases may be generated above the upper part of the heating wire cutter 121, above the outlet of the funnel 180, and inside the cooling cavity 161. In order to ensure that these waste gases do not pollute the environment, an exhaust gas filtering assembly is provided. The first suction pipeline, the second suction pipeline, and the third suction pipeline respectively suck these waste gases into the vacuum pump 190. The vacuum pump 190 concentrates the waste gases through its strong suction force and transports them to the filtering device 200 for treatment. Multiple layers of filtering materials are provided inside the filtering device 200. First, it is preliminarily filtered through a sponge filter layer to remove larger particulate matters. Subsequently, the waste gas enters the carbon adsorption material filter layer, which utilizes the adsorption properties of materials such as carbon powder, sand, and glutinous rice to effectively adsorb harmful substances in the waste gas. Finally, the waste gas passes through the carbon cotton filter layer for further purification to ensure that the finally discharged gas meets the environmental protection standards. The third motor serves as a power source to drive the vacuum pump 190 to continuously work, ensuring the efficient operation of the exhaust gas filtering assembly. The design of the entire exhaust gas filtering assembly fully considers environmental protection and practicality, effectively avoiding the pollution of the environment by waste gases during the conversion process.

[0109] Specifically, the disposable plastic bag conversion machine further includes:

[0110] A sewage guiding groove, located outside the conversion machine housing 100 and below the bag inlet.

[0111] A liquid storage tank, provided on one side of the conversion machine housing 100, and the liquid storage tank is connected to the liquid outlet end of the sewage guiding groove.

[0112] It can be understood that a sewage guiding groove is provided below the bag inlet. Some plastic bags may have a part of liquid remaining in them, such as water, grease, soup, etc. When putting a plastic bag containing liquid into the bag inlet, due to the squeezing action of the pair of rollers at the bag inlet, the liquid is squeezed out of the plastic bag, and the squeezed-out liquid will flow into the liquid storage tank through the sewage guiding groove for temporary storage. When the liquid storage tank has collected a lot of liquid, the user can remove the liquid storage tank by himself / herself, pour out the dirt in it, clean it, and then reinstall it to continue using.

[0113] The working process of the disposable plastic bag converter involved in the present invention is as follows: When the plastic bag enters the interior of the converter housing 100 through the bag inlet, the infrared probe located at the bag inlet will detect. Once the infrared ray is blocked, the first motor 125 will start immediately to provide power for the operation of the machine, and at the same time, the pair of rollers at the bag inlet will also start to rotate; the four heating wires of the heating wire cutter 121 will quickly heat up to the preset temperature; subsequently, the cutting knife group will also start to rotate. The above three links are all controlled for power on and off through the disconnection and connection of the infrared ray. The two ends of the pair of rollers at the bag inlet are fixed inside the fixing frame 112. Two small springs are respectively arranged between the two ends of the driving flower roller 111 and the fixing frame 112 to press the pair of rollers at the bag inlet. Once the input plastic bag is too thick, it will be stuck at the bag inlet, resulting in too large a rotational resistance of the first motor 125. The circuit control board will instruct the first motor 125 to reverse for 3 seconds and pause for 5 seconds; after pushing out the too thick plastic bag, at this time the infrared ray is in a connected state, and the first motor 125 is in a standby state and stops rotating.

[0114] The second motor 154 is responsible for providing power for the hot melting assembly, and its start and stop states change with the on and off states of the infrared ray at the bag inlet. When the infrared ray is disconnected, the second motor 154 starts immediately and begins to work. When 60 seconds after the infrared ray is connected, the second motor 154 stops rotating.

[0115] The third motor is responsible for providing power for the vacuum pump 190, and its start and stop states also change with the on and off states of the infrared ray at the bag inlet. When the infrared ray is disconnected, the third motor starts and begins to rotate. After 40 seconds when the infrared ray is connected, the third motor stops rotating.

[0116] After the hot melting assembly is turned on the main power supply, it starts to preheat. When the main power switch is turned on, the hot melting assembly heats the temperature to the specified temperature of 80 degrees Celsius, which is controlled by the temperature controller, and then is in a standby state; when the infrared ray at the bag inlet is disconnected, the temperature will rise to the specified temperature of 300 degrees Celsius. At this time, the three motors and the hot melting assembly of the machine are all in a working state.

[0117] A set of cooling components is provided at the discharge port of the hot melting assembly, and its working instruction is: when the power switch of the machine is turned on, the refrigerating sheet starts to refrigerate, and when the second motor 154 stops running, the refrigerating sheet stops refrigerating.

[0118] A tipping switch is also set inside the machine. Only when the machine is placed correctly can it be powered on, otherwise the main switch is not powered on.

[0119] The circuit board is equipped with components for automatic power off in case of short circuit and has an overcurrent protection function.

[0120] There are four heating wires on the heating wire cutter 121 driven by the first motor 125. If any one of these heating wires is disconnected, the power supply will automatically cut off, the entire machine will stop working, and an alarm sound will be accompanied as a prompt tone.

[0121] A trigger is provided at the collection box 170. If the collection box 170 is not reset, when the main switch of the machine is powered on and the infrared ray is disconnected, a prompt tone will sound; after the collection box 170 is reset, the prompt tone stops and the machine operates normally.

[0122] An inductor should be installed at the entrance of the collection box 170. When the collection box 170 is full, a prompt tone will sound and the indicator light will turn on.
