Description

Technical Field

[0001] The invention relates to the field of plastic parts recycling, in particular to a plastic parts production device and a use method thereof. Background Art

[0002] Plastic raw materials are defined as a synthetic or natural high molecular polymer that can be arbitrarily molded into various shapes and can finally maintain the same shape of the material or plastic material product. Plastic is a high molecular compound polymerized from monomers through addition or condensation reactions. Its deformation resistance is medium, between fiber and rubber. It is composed of synthetic resins and additives such as fillers, plasticizers, stabilizers, lubricants, and colorants.

[0003] The main component of plastic is resin. Resin refers to a polymer compound that has not been mixed with various additives. The term resin was originally named after the lipids secreted by animals and plants, such as rosin and shellac. Resin accounts for about 40% to 100% of the total weight of plastic. The basic properties of plastics are mainly determined by the nature of the resin, but additives also play an important role. Some plastics are basically composed of synthetic resins, without or with little additives, such as plexiglass. Environmentally friendly plastics generally include reusable, renewable and degradable categories. Among them, reusable environmentally friendly plastics can significantly optimize the utilization rate of resources. After the same batch of environmentally friendly plastics is used, it can be synthesized into plastic products for various occasions according to different use cycles. There is no need to start the synthesis of plastic products from scratch, saving manpower and material resources. However, in the process of reusing environmentally friendly plastic products, due to the different use environments and types of environmentally friendly plastic products of the same material, different types of stains and impurities are often adhered to their outer surfaces. They need to be cleaned intensively in the early stage of recycling. However, in the process of cleaning environmentally friendly plastic products, the following problems often exist:

[0004] Since environmentally friendly plastic products often appear in a piled-up state during the collection and cleaning process, traditional cleaning methods are difficult to effectively clean and flush environmentally friendly plastic products in a piled-up state, and are unable to timely isolate impurities dropped during the cleaning process from environmentally friendly plastic products, which can easily cause secondary adsorption pollution and increase the workload of cleaning operations. In addition, it is difficult to guide and transport cleaning water in a centralized manner during the cleaning process, which increases pollution to the surrounding environment and the workload of subsequent cleaning and maintenance. Summary of the invention

[0005] In view of the problems in the prior art, the present invention provides a plastic part production device and a use method thereof.

[0006] The technical solution adopted by the present invention to solve its technical problems is: a plastic parts production device, including a base plate, supporting feet, a liquid storage tank, a cleaning box, an immersion cylinder, a feed port, a discharge port, a cleaning mechanism and a spray mechanism, wherein supporting feet are installed at the corners around the lower end surface of the base plate, a cleaning box is installed at the middle part of the upper end surface of the base plate, and a liquid storage tank is symmetrically installed on the upper end surface of the base plate, the liquid storage tanks are respectively located on the left and right sides of the cleaning box and the liquid storage tanks are connected with the cleaning box, an immersion cylinder is fixedly installed on the inner side of the front end of the cleaning box, a feed port and a discharge port are opened at the upper end of the immersion cylinder, the immersion cylinder and the cleaning box are jointly installed with a cleaning mechanism, a spray mechanism is installed on the inner side of the rear end of the cleaning box, and the spray mechanism is located below the discharge port; spoiler nozzles are evenly installed on the bottom of the cleaning box, and the spoiler nozzles are located below the immersion cylinder.

[0007] The cleaning mechanism comprises a cleaning shaft, a cleaning rack, a stirring shaft, a stirring disk, a stirring spring, a brake rod, a brake cam, a guide plate, a guide spring and a cleaning motor. The cleaning shaft is installed through the central part of the immersion cylinder via a bearing, and both ends of the cleaning shaft are fixedly connected to the left and right side walls of the cleaning box via bearings. A cleaning motor is fixedly installed on one side wall of the cleaning box via a motor seat. The output shaft of the cleaning motor is transmission-connected to one end of the cleaning shaft via a coupling. A cleaning rack is symmetrically installed on the middle part of the cleaning shaft via a key connection. The cleaning racks are all located in the immersion cylinder and multiple groups of stirring shafts are installed between the cleaning racks via bearings. A stirring plate is installed in the middle part by means of a key connection. The stirring plate is located between the cleaning racks and the bottom of the stirring plate near one end of the cleaning shaft is connected to the cleaning rack by a stirring spring. Brake rods are symmetrically installed at both ends of the stirring shaft by means of a key connection. Braking protrusions are symmetrically provided on the left and right side walls of the discharge port, and the braking protrusions are slidingly matched with the brake rods. A guide plate is installed at the bottom end of the inner side of the groove of the discharge port by means of a rotational fit. An inclined upward lower side is provided on the inner side of the guide plate. The lower end surface of the guide plate is connected to the side wall of the groove of the discharge port by a guide spring. The automatic discharge of plastic products after cleaning can be achieved by docking the brake rod with the brake protrusion.

[0008] Specifically, the braking bump is installed obliquely on both sides of the notch of the discharge chute, and the side walls of the braking bump are evenly provided with spherical protrusions. The spherical protrusions arranged on the side walls of the braking bump can enable the stirring plate to provide a vibration effect within a certain degree of freedom during the tilting and flipping process, thereby enhancing the sliding effect of plastic products on the upper surface of the stirring plate, and at the same time shaking off some adhered stains and floating objects through the vibration effect.

[0009] Specifically, a hollow notch is provided in the middle of the stirring plate, a drain rod is evenly installed in the notch by means of a key connection, a drain convex strip is installed in the middle of the drain rod by means of a rotational fit, the upper end of the drain convex strip is a fan-shaped arc structure, and a counterweight block is evenly installed on the lower end of the drain convex strip by means of a rotational fit, and the movably installed drain convex strip can facilitate the rapid penetration of the solution, so that the solution in the initial cleaning process can be retained in the immersion cylinder to the greatest extent, thereby reducing pollution to the surrounding environment.

[0010] Specifically, a fence plate is circumferentially arranged on the stirring disk, and a funnel-shaped notch inclined inwardly is arranged on the fence plate near the edge of the immersion tube.

[0011] Specifically, the two ends of the cleaning shaft are symmetrically installed with dredging racks by key connection, and the ends of the dredging racks are installed with dredging wheels by rotational cooperation. Fixed rods are evenly installed on the arc side walls of the immersion cylinder, and dredging grooves are symmetrically and evenly opened on the arc side walls of the immersion cylinder. The dredging grooves and the fixed rods are arranged at intervals and a dredging slide rod is installed in the dredging groove between two adjacent fixed rods by sliding cooperation. Staggered protrusions are symmetrically installed on the middle part of the dredging slide rod, and the staggered protrusions are linearly aligned with the dredging wheel and spring sheets are arranged between the staggered protrusions. The self-cleaning operation of the multi-station gap can avoid the probability of impurity particles causing blockage of the solution flow path, thereby reducing the workload of later cleaning and maintenance.

[0012] Specifically, the dredging sliding rod and two adjacent fixed rods are arranged in a triangle shape, and a gap is reserved between the dredging sliding rod and the fixed rods.

[0013] Specifically, the spray mechanism includes a discharge plate, a conveying shaft, a conveying plate, a leakage rod, a limiting ring, a spray frame, an inclined plate, an exhaust port and a material receiving net. The discharge plate is fixedly installed on the outer side of the bottom groove of the discharge port, and the end of the discharge plate is inclined downward. The conveying shaft is commonly installed between the left and right side walls of the rear end of the cleaning box through bearings, and the middle part of the conveying shaft is installed with a conveying plate by a key connection. Both sides of the conveying plate are connected to the side walls of the cleaning box through torsion springs, and in a natural state, under the torsion force of the torsion springs, the end of the conveying plate is tilted and lifted upward in the inclined box, and limiting rings are symmetrically installed on the inner side of the cleaning box from top to bottom, the limiting rings are all located below the discharge plate and the end of the conveying plate is located between the limiting rings, and the rear end of the cleaning box is linearly arranged. A spray rack is installed above the conveying plate, and nozzles are evenly installed on the spray rack and the spray rack is connected to the existing water supply and drainage facilities. An inclined plate is installed in the cleaning box, and the inclined plate is located below the end of the conveying plate and the angle between the inclined plate and the conveying plate is an acute angle. Exhaust ports are evenly arranged on the inclined plate, and the exhaust ports are connected to the existing air pump. A material receiving net is installed at the rear end of the cleaning box by a sliding fit, and the material receiving net is located below the inclined plate. The stains adhered to the surface of the plastic products can be sprayed and removed for the second time through the flushing of the spray rack. The air output through the exhaust port can enhance the vibration effect of the conveying plate and the plastic products, and can also blow and clean the fallen stains and debris, and cooperate with the flushing of the water flow to make the stains fall onto the material receiving net below for secondary collection.

[0014] Specifically, the liquid storage tank is connected to the existing water supply and drainage facilities through a water pipe. A water inlet is provided at the upper end of the liquid storage tank on one side of the cleaning tank, and a water outlet is provided at the lower end of the liquid storage tank on the other side of the cleaning tank. The existing water supply and drainage facilities replace the clean water for the liquid storage tank and the inside of the cleaning tank in a regular and quantitative manner through the water inlet and the water outlet.

[0015] Specifically, the left and right side walls of the immersion cylinder are both open structures, and the left and right opening positions of the immersion cylinder are completely covered with filter covers with the same structure, and filter screens are arranged at the arc edge positions of the filter covers.

[0016] Specifically, the spoiler nozzles are connected to the existing air pumps. The airflow ejected by the spoiler nozzles can form a large number of bubbles in the water. The continuous delivery and surging of the bubbles causes the clean water in the immersion cylinder and the inside of the cleaning box to roll and fluctuate continuously. The plastic products are synchronously rolled under the tumbling action of the water flow itself, and the stains adhered to their surfaces are continuously impacted.

[0017] The present invention also provides a method for using the plastic part production device, the method comprising the following steps:

[0018] Step 1: manually connect the water inlet and outlet on the liquid storage tanks on both sides to the water inlet and outlet of the water supply and drainage system respectively;

[0019] Step 2: close the water outlet, inject a proper volume of clean water into the water inlet, the injected water flows through the liquid storage tank into the cleaning tank, and after the water flow is injected, the lower end of the immersion cylinder is immersed in water;

[0020] Step 3: Continuously inject air into the spoiler nozzle through the air pump. Since the spoiler nozzle is submerged in the water at this time, a large number of bubbles are formed in the water when the airflow is ejected outward from the spoiler nozzle. Some bubbles pass through the filter on the filter cover and enter the inner side of the immersion tube during the process of floating up. The continuous transportation and surging of the bubbles causes the immersion tube and the clean water inside the cleaning box to continuously roll and fluctuate.

[0021] Step 4: Put the environmentally friendly plastic products of appropriate volume to be cleaned into the immersion cylinder from the feed port manually or by an existing robot. The stains adhering to the surface of the plastic products are continuously impacted and removed by the tumbling action of the water flow.

[0022] Beneficial effects of the present invention:

[0023] (1) The airflow ejected by the turbulent nozzle of the present invention can form a large number of bubbles in the water. The continuous conveying and surging of the bubbles causes the clean water in the immersion tube and the inner side of the cleaning box to continuously roll and fluctuate. The plastic products are synchronously rolled under the rolling action of the water flow itself, and the stains adhered to the surface are continuously impacted. The stains adhered to the surface of the plastic products can be sprayed and removed by the flushing of the spray rack. The air output through the exhaust port can not only enhance the vibration effect of the conveying plate and the plastic products, but also blow and clean the fallen stains and debris. The flushing of the water flow causes the stains to fall onto the receiving net below for secondary collection.

[0024] (2) The present invention can realize the automatic discharge operation of plastic products after cleaning through the docking cooperation between the brake rod and the brake protrusion. The spherical protrusions arranged on the side walls of the brake protrusions can provide a vibration effect within a certain degree of freedom during the tilting and flipping process of the stirring plate, thereby enhancing the sliding effect of the plastic products on the upper surface of the stirring plate, and at the same time shaking off some adhered stains and floating objects through the vibration effect.

[0025] (3) The movably installed drainage ribs of the present invention can facilitate the rapid penetration of the solution, so that the solution in the initial cleaning process can be retained in the immersion tube to the greatest extent, reducing pollution to the surrounding environment. The self-cleaning operation of the multi-station gap can avoid the probability of impurity particles causing blockage of the solution flow path, reducing the workload of subsequent cleaning and maintenance.

[0040] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0041] See also Figures 1 to 3 A plastic parts production device comprises a substrate 1, a supporting foot 2, a liquid storage tank 3, a cleaning tank 4, an immersion cylinder 5, a feed port 6, a discharge port 7, a cleaning mechanism 8 and a spray mechanism 9. The supporting feet 2 are installed at the corners around the lower end surface of the substrate 1, the cleaning tank 4 is installed in the middle of the upper end surface of the substrate 1, the liquid storage tank 3 is symmetrically installed on the upper end surface of the substrate 1, the liquid storage tank 3 is respectively located on the left and right sides of the cleaning tank 4 and the liquid storage tank 3 is connected to the cleaning tank 4, an immersion cylinder 5 is fixedly installed on the inner side of the front end of the cleaning tank 4, a feed port 6 and a discharge port 7 are opened at the upper end of the immersion cylinder 5, the immersion cylinder 5 and the cleaning tank 4 are jointly installed with a cleaning mechanism 8, a spray mechanism 9 is installed on the inner side of the rear end of the cleaning tank 4, and the spray mechanism 9 is located below the discharge port 7.

[0042] See also Figures 1 to 3 The liquid storage tank 3 is connected with the existing water supply and drainage facilities through a water pipe. A water inlet 31 is provided at the upper end of the liquid storage tank 3 located on one side of the cleaning tank 4, and a water outlet 32 ​​is provided at the lower end of the liquid storage tank 3 located on the other side of the cleaning tank 4. The existing water supply and drainage facilities replace the cleaning water for the inner side of the liquid storage tank 3 and the cleaning tank 4 in a regular and quantitative manner through the water inlet 31 and the water outlet 32. The left and right side walls of the immersion cylinder 5 are both open structures, and the left and right side opening positions of the immersion cylinder 5 are completely covered and installed with filter screen covers 53 of the same structure, and filter screens are provided at the arc edge positions of the filter screen covers 53. Disturbing nozzles 41 are evenly installed at the bottom of the cleaning tank 4. The disturbing nozzles 41 are located below the immersion cylinder 5 and the disturbing nozzles 41 are all connected to the existing air pump.

[0043] During the specific operation, firstly, the water inlet 31 and the water outlet 32 ​​on the liquid storage tanks 3 on both sides are manually connected to the water inlet and the water outlet of the existing water supply and drainage system respectively, then the water outlet 32 ​​is closed, and an appropriate volume of clean water is injected into the water inlet 31, and the injected water flows through the liquid storage tank 3 into the cleaning tank 4, and after the water flow is injected, the lower end of the immersion tube 5 is immersed in the water, and then, air is continuously injected into the spoiler nozzle 41 through the existing air pump. Since the spoiler nozzle 41 is sunk in the water at this time, a large number of bubbles are formed in the water when the air flow is sprayed outward from the spoiler nozzle 41, and part of the bubbles are During the process of floating up, the bubbles pass through the filter on the filter cover 53 and enter the inner side of the immersion cylinder 5. The continuous conveying and surging of the bubbles causes the clean water in the immersion cylinder 5 and the cleaning box 4 to continuously roll and fluctuate. After that, the environmentally friendly plastic products of a suitable volume to be cleaned are put into the immersion cylinder 5 from the feed port 6 manually or by an existing robot. After that, the stains adhered to the surface of the plastic products are continuously impacted and removed by the tumbling action of the water flow itself. Some muddy stains are immediately dissolved and pass through the filter cover 53 into the cleaning box 4, and the flushing operation is performed for an appropriate period of time.

[0044] See also Figure 3 , Figure 6 , Figure 8 and Fig. 9The cleaning mechanism 8 includes a cleaning shaft 81, a cleaning rack 82, an agitating shaft 83, an agitating disk 84, an agitating spring 85, a brake rod 86, a brake bump 87, a guide plate 88, a guide spring 89 and a cleaning motor 810. The cleaning shaft 81 is installed through the central part of the immersion tube 5 through a bearing, and both ends of the cleaning shaft 81 are fixedly connected to the left and right side walls of the cleaning box 4 through bearings. A cleaning motor 810 is fixedly installed on one side wall of the cleaning box 4 through a motor seat. The output shaft of the cleaning motor 810 is transmission-connected to one end of the cleaning shaft 81 through a coupling. The middle part of the cleaning shaft 81 is symmetrically installed with a cleaning rack 82 by a key connection. The cleaning racks 82 are all located in the immersion tube 5 and multiple cleaning racks 82 are installed between the cleaning racks 82 through bearings. A stirring shaft 83 is formed, and a stirring disk 84 is installed in the middle of the stirring shaft 83 by a key connection. The stirring disk 84 is located between the cleaning racks 82 and the bottom of the stirring disk 84 close to one end of the cleaning shaft 81 is connected to the cleaning rack 82 by a stirring spring 85. Brake rods 86 are symmetrically installed at both ends of the stirring shaft 83 by a key connection. Braking protrusions 87 are symmetrically arranged on the left and right side walls of the discharge port 7. The side walls of the braking protrusions 87 are evenly provided with spherical protrusions 871 and the braking protrusions 87 are slidably matched with the brake rods 86. A guide plate 88 is installed at the bottom end of the inner side of the slot of the discharge port 7 by a rotational fit. The inner side of the guide plate 88 is provided with a lower side inclined upward, and the lower end surface of the guide plate 88 is connected to the side wall of the slot of the discharge port 7 by a guide spring 89.

[0045] In specific operation, after the stains on the surface of the plastic product are initially rinsed, the cleaning motor 810 is started to rotate counterclockwise, and the cleaning shaft 81 is driven by the cleaning motor 810 to rotate counterclockwise. During the rotation of the cleaning shaft 81, the cleaning rack 82 is driven to rotate synchronously in the circumferential direction. During the circumferential rotation of the cleaning rack 82, the transmission connection between the stirring shaft 83 and the stirring spring 85 drives the stirring plate 84 to rotate synchronously in the circumferential direction. During the counterclockwise rotation of the stirring plate 84, part of the plastic product inside the immersion tube 5 is synchronously moved. The cleaning rack 82 is used to scoop up the plastic products and drive them to rotate synchronously. The inclined surface on the guide plate 88 can actively make way for the moving path of the stirring plate 84 and reset itself by the elastic force of the guide spring 89 after the stirring plate 84 passes over. When the cleaning rack 82 drives the stirring plate 84 to rotate circumferentially to the lower end of the notch of the discharge port 7, the end of the brake rod 86 begins to abut against the lower end of the brake protrusion 87. Since the brake rod 86 is obliquely fixed to the notch of the discharge port 7, it is blocked by the brake protrusion 87 and stops moving. At this time, the cleaning rotating frame 82 is still rotating in the circumferential direction. The braking effect of the braking protrusion 87 on the braking rod 86 causes the stirring plate 84 to start to flip around the stirring rotating shaft 83 as the rotation center through the transmission connection of the stirring rotating shaft 83, and the stirring spring 85 is gradually in a stretched state during the flipping process. In the process of the tilting and flipping of the stirring plate 84, the plastic products accumulated on the upper surface of the stirring plate 84 begin to slide toward the discharge port 7 under the action of gravity. The guide plate 88 provided can guide the plastic products in the falling process for a second time, so that the plastic products The stirring disk 84 falls to the outside of the immersion cylinder 5. When the inclination angle of the stirring disk 84 reaches a preset value, the brake rod 86 begins to slide upward along the inclined side wall of the brake protrusion 87, and under the inclined guiding action of the brake protrusion 87, the inclination angle of the stirring disk 84 is further increased. The spherical protrusion 871 arranged on the side wall of the brake protrusion 87 can provide a vibration effect within a certain degree of freedom for the stirring disk 84 during the tilting and flipping process, thereby enhancing the sliding effect of the plastic products on the upper surface of the stirring disk 84 and shaking off some adhered stains and floating objects through the vibration effect.

[0046] See also Figures 9 to 12 A hollow slot is provided in the middle of the stirring disk 84, and a drain rod 841 is evenly installed in the slot by a key connection. A drain rib 8411 is installed in the middle of the drain rod 841 by a rotational fit. The upper end of the drain rib 8411 is a fan-shaped arc structure, and a counterweight block 8412 is evenly installed on the lower end of the drain rib 8411 by a rotational fit. A fence plate 842 is circumferentially arranged on the stirring disk 84, and a funnel-shaped notch inclined inward is arranged on the fence plate 842 near the edge of the immersion tube 5.

[0047] During specific operation, when the stirring disk 84 scoops up the plastic products, the fence plate 842 can increase the single scooping volume of the plastic products by the stirring disk 84, and the funnel-shaped notch at the end of the fence plate 842 can increase the concentration of the plastic products when they slide down at the discharge port 7 in the later stage. The movably installed drainage ridges 8411 can facilitate the rapid penetration of the solution, so that the solution in the initial cleaning process is retained in the immersion cylinder 5 to the greatest extent, and the counterweight block 8412 can make the drainage ridges 8411 themselves tilt and rotate during the circumferential rotation of the stirring disk 84, thereby causing the gap between the two adjacent drainage ridges 8411 to produce a dislocation change, and the self-cleaning of the gap can avoid the blockage of the solution flow path caused by the solute particles mixed in the solution.

[0048] See also Figure 3 , Figure 6 , Figure 7 and Fig.10 The two ends of the cleaning shaft 81 are symmetrically installed with dredging rotating frames 811 by key connection, and the end of the dredging rotating frame 811 is installed with a dredging wheel 8111 by rotational cooperation. The fixed rods 51 are evenly installed on the arc side walls of the immersion cylinder 5, and the dredging slide grooves 52 are symmetrically and evenly opened on the arc side walls of the immersion cylinder 5. The dredging slide grooves 52 are arranged at intervals with the fixed rods 51, and a dredging slide rod 521 is installed in the dredging slide groove 52 between the two adjacent fixed rods 51 by sliding cooperation. The dredging slide rod 521 and the two adjacent fixed rods 51 are arranged in a triangular shape, and a gap is reserved between the dredging slide rod 521 and the fixed rod 51. The middle part of the dredging slide rod 521 is symmetrically installed with staggered protrusions 522, and the staggered protrusions 522 are linearly aligned with the dredging wheel 8111 and a spring sheet 523 is provided between the staggered protrusions 522.

[0049] In specific operation, during the cleaning operation of plastic products, since there is a gap reserved between the fixed rod 51 and the dredging sliding rod 521, some impurity particles generated during the cleaning process pass through the reserved gap under the action of gravity and reach the bottom of the cleaning box 4. During the rotation of the cleaning shaft 81, the dredging rotating frame 811 is driven to rotate synchronously in a circumferential direction, and the dredging rotating frame 811 drives the dredging wheel 8111 to rotate synchronously in a circumferential direction. When the dredging wheel 8111 rotates to the middle and lower position of the immersion cylinder 5, the circumferential direction is further rotated. The misaligned protrusion 522 on the rotating path forms an extrusion, causing the misaligned protrusion 522 to move close to the outer wall of the immersion cylinder 5, and at this time, the spring sheet 523 is gradually in a compressed state due to the movement of the misaligned protrusion 522. During the movement of the misaligned protrusion 522, the dredging slide rod 521 is driven to slide synchronously in the dredging slide groove 52. The displacement of the dredging slide rod 521 can change the gap between the dredging slide rod 521 and the fixed rod 51, thereby further eliminating the impurity particles that are blocked and stuck in the reserved gap.

[0050] See also Figure 3 The spray mechanism 9 includes a discharge plate 91, a conveying shaft 92, a conveying plate 93, a leakage rod 94, a limit ring 95, a spray frame 96, an inclined plate 97, an exhaust port 98 and a material receiving net 99. The discharge plate 91 is fixedly installed on the outer side of the bottom notch of the discharge port 7, and the end of the discharge plate 91 is tilted downward. The conveying shaft 92 is commonly installed between the left and right side walls of the rear end of the cleaning box 4 through a bearing. The middle part of the conveying shaft 92 is installed with a conveying plate 93 by a key connection. The middle part of the conveying plate 93 is evenly installed with a leakage rod 94 by a key connection. Both sides of the conveying plate 93 are connected to the side walls of the cleaning box 4 by a torsion spring, and in a natural state, under the torsion of the torsion spring, the end of the conveying plate 93 is tilted upward in the tilting box. Lift up, limit rings 95 are symmetrically installed on the inner side of the cleaning box 4, the limit rings 95 are all located below the discharge plate 91 and the end of the conveying plate 93 is located between the limit rings 95, the rear end of the cleaning box 4 is linearly installed with a spray rack 96, the spray rack 96 is located above the conveying plate 93, and nozzles are evenly installed on the spray rack 96, and the spray rack 96 is connected to the existing water supply and drainage facilities, an inclined plate 97 is installed in the cleaning box 4, the inclined plate 97 is located below the end of the conveying plate 93 and the angle between the inclined plate 97 and the conveying plate 93 is an acute angle, exhaust ports 98 are evenly arranged on the inclined plate 97, and the exhaust ports 98 are all connected to the existing air pump, and the rear end of the cleaning box 4 is installed with a material receiving net 99 by a sliding fit, and the material receiving net 99 is located below the inclined plate 97.

[0051] In specific operation, after the plastic products are initially cleaned and discharged from the discharge port 7, they further fall downward onto the conveying plate 93 due to gravity and the guiding support of the discharge plate 91. Afterwards, under the impact of the plastic products, the torsion spring is subjected to cyclic compression and causes the conveying plate 93 to swing continuously. The set limit ring 95 can limit the overall swing angle of the conveying plate 93. In the process of the plastic products falling, clean water is injected into the spray rack 96 through the existing water supply and drainage system. The clean water is pressurized by the spray rack 96 and directly sprayed on the upper surface of the conveying plate 93, so as to further spray and remove the stains adhering to the surface of the plastic products. At the same time, the existing air pump is used to spray and remove the stains. Air is continuously injected into the exhaust port 98, and the output air is blown to the lower end surface of the conveying plate 93 at an acute angle through the inclined guiding effect of the inclined plate 97. The airflow can not only enhance the vibration effect of the conveying plate 93 and the plastic products, but also blow and clean the fallen stains and debris. With the flushing of the water flow, the stains fall to the receiving net 99 below for secondary collection. After cleaning, the plastic products are shaken off to the outside of the cleaning box 4 through natural vibration, and then collected and dried manually or by existing robots. After a single batch of plastic products is cleaned, the clean water inside the cleaning box is replaced through the existing water supply and drainage system, which is convenient for the next batch of plastic products to be cleaned.

[0052] The specific method of using the present invention is as follows: Step 1: First, manually connect the water inlet 31 and the water outlet 32 ​​on the liquid storage tanks 3 on both sides to the water inlet and the water outlet of the existing water supply and drainage system respectively, then close the water outlet 32, inject a proper volume of clean water into the water inlet 31, and the injected water flows through the liquid storage tank 3 into the cleaning tank 4, and after the water flow is injected, the lower end of the immersion tube 5 is immersed in water, and then, air is continuously injected into the spoiler nozzle 41 through the existing air pump. Since the spoiler nozzle 41 is submerged in the water at this time, when the airflow is sprayed outward from the spoiler nozzle 41, a large amount of water is formed in the water. The bubbles are measured, and some of them pass through the filter on the filter cover 53 and enter the inner side of the immersion tube 5 during the floating process. The continuous conveying and surging of the bubbles causes the clean water in the immersion tube 5 and the cleaning box 4 to continuously roll and fluctuate. After that, the environmentally friendly plastic products of a suitable volume to be cleaned are put into the immersion tube 5 from the feed port 6 manually or by an existing robot. After that, the stains adhered to the surface of the plastic products are continuously impacted and removed by the tumbling action of the water flow itself, and some of the muddy stains are immediately dissolved and pass through the filter cover 53 into the cleaning box 4, so that the flushing operation is carried out for an appropriate time.

[0053] Step 2: After the stains on the surface of the plastic product are initially rinsed, the cleaning motor 810 is started to rotate counterclockwise, and the cleaning shaft 81 is driven by the cleaning motor 810 to rotate counterclockwise. During the rotation of the cleaning shaft 81, the cleaning rack 82 is driven to rotate synchronously in a circumferential direction. During the circumferential rotation of the cleaning rack 82, the transmission connection between the stirring shaft 83 and the stirring spring 85 drives the stirring plate 84 to rotate synchronously in a circumferential direction. During the counterclockwise circumferential rotation of the stirring plate 84, part of the plastic products inside the immersion tube 5 are synchronously scooped up, and the scooped plastic products are driven to rotate synchronously in a circumferential direction. The inclined surface on the guide plate 88 can actively make way for the moving path of the stirring plate 84, and after the stirring plate 84 passes over, it is automatically reset by the elastic force of the guide spring 89.

[0054] The third step: when the cleaning rotating frame 82 drives the stirring plate 84 to rotate circumferentially to the lower end position of the notch of the discharge port 7, the end of the brake rod 86 begins to abut against the lower end of the brake protrusion 87. Since the brake rod 86 is obliquely fixed to the notch of the discharge port 7, it is blocked by the brake protrusion 87 and begins to stop moving. Since the cleaning rotating frame 82 is still rotating circumferentially at this time, the braking effect of the brake protrusion 87 on the brake rod 86 causes the stirring plate 84 to start to flip around the stirring shaft 83 as the rotation center through the transmission connection of the stirring shaft 83, and the stirring spring 85 is gradually in a stretched state during the flipping process. In the process of tilting and flipping the stirring plate 84, the plastic products accumulated on the upper surface of the stirring plate 84 are Under the action of gravity, it starts to slide toward the discharge port 7. The guide plate 88 provided can provide secondary guidance for the plastic products in the falling process, so that the plastic products fall to the outside of the immersion cylinder 5. When the inclination angle of the stirring disk 84 reaches the preset value, the brake rod 86 starts to slide upward along the inclined side wall of the brake protrusion 87, and under the inclined guiding action of the brake protrusion 87, the inclination angle of the stirring disk 84 is further increased. The spherical protrusion 871 provided on the side wall of the brake protrusion 87 can provide a vibration effect within a certain degree of freedom for the stirring disk 84 during the tilting and flipping process, thereby enhancing the sliding effect of the plastic products on the upper surface of the stirring disk 84, and at the same time shaking off some adhered stains and floating objects through the vibration effect.

[0055] Step 4: During the process of the stirring disk 84 scooping up the plastic products, the fence plate 842 can increase the single scooping volume of the plastic products by the stirring disk 84, and the funnel-shaped notch at the end of the fence plate 842 can increase the concentration of the plastic products when they slide down at the discharge port 7 in the later stage. The movably installed drainage ridges 8411 can facilitate the rapid penetration of the solution, so that the solution in the initial cleaning process is retained in the immersion cylinder 5 to the greatest extent, and the counterweight block 8412 can make the drainage ridges 8411 themselves tilt and rotate during the circumferential rotation of the stirring disk 84, thereby causing the gap between two adjacent drainage ridges 8411 to produce a dislocation change, and the self-cleaning of the gap can avoid the blockage of the solution flow path caused by the solute particles mixed in the solution.

[0056] Step 5: During the cleaning of plastic products, since there is a gap between the fixed rod 51 and the dredging slide rod 521, some impurity particles generated during the cleaning process pass through the reserved gap under the action of gravity and reach the bottom of the cleaning box 4. During the rotation of the cleaning shaft 81, the dredging rotating frame 811 is driven to rotate synchronously, and the dredging rotating frame 811 drives the dredging wheel 8111 to rotate synchronously. When the dredging wheel 8111 rotates to the middle and lower position of the immersion cylinder 5, the dredging rotating frame 8111 is further rotated. The misaligned protrusion 522 on the moving path forms an extrusion, causing the misaligned protrusion 522 to move close to the outer wall of the immersion cylinder 5, and at this time, the spring sheet 523 is gradually in a compressed state due to the movement of the misaligned protrusion 522. During the movement of the misaligned protrusion 522, the dredging slide rod 521 is driven to slide synchronously in the dredging slide groove 52. The displacement of the dredging slide rod 521 can change the gap between the dredging slide rod 521 and the fixed rod 51, thereby further eliminating the impurity particles that are blocked and stuck in the reserved gap.

[0057] Step 6: After the plastic products are discharged from the discharge port 7 after the preliminary cleaning, they further fall downward onto the conveying plate 93 due to gravity and the guiding support of the discharge plate 91. Afterwards, under the impact of the plastic products, the torsion spring is subjected to cyclic compression and causes the conveying plate 93 to swing continuously. The set limit ring 95 can limit the overall swing angle of the conveying plate 93. In the process of the plastic products falling, clean water is injected into the spray rack 96 through the existing water supply and drainage system. The clean water is pressurized by the spray rack 96 and directly sprayed on the upper surface of the conveying plate 93, so as to further spray and remove the stains adhering to the surface of the plastic products. At the same time, the existing air pump is used to Air is continuously injected into the exhaust port 98, and the output air is blown to the lower end surface of the conveying plate 93 at an acute angle through the inclined guiding effect of the inclined plate 97. The airflow can not only enhance the vibration effect of the conveying plate 93 and the plastic products, but also blow and clean the fallen stains and debris. With the flushing of the water flow, the stains fall to the receiving net 99 below for secondary collection. After cleaning, the plastic products are shaken off to the outside of the cleaning box 4 through natural vibration, and then collected and dried manually or by existing robots. After a single batch of plastic products is cleaned, the clean water inside the cleaning box is replaced through the existing water supply and drainage system, which is convenient for the next batch of plastic products to be cleaned.
