Description

Technical Field

[0001] This invention relates to the field of waste recycling technology, and in particular to a recycling and regeneration device for automotive injection molded parts waste. Background Technology

[0002] Glass fiber reinforced plastic (GFRP) injection molded parts, with their outstanding advantages such as high specific strength, excellent heat resistance, and good dimensional stability, are widely used in automotive bumpers, dashboard frames, and underbody protection panels. With the deepening trend of automotive lightweighting and increasingly stringent requirements for recycling, the efficient handling of large amounts of GFRP injection molding waste generated from end-of-life vehicles and the production process has become a key issue of focus for the industry. This waste needs to undergo a crushing process to transform it into uniform fragments that are easy to sort, clean, and granulate later. Currently, the industry commonly uses fiberglass crushers to process these high-toughness, high-wear-resistant materials.

[0003] Existing fiberglass crushers typically incorporate multiple layers of flexible baffles at the feed inlet to reduce the splashing of debris and dust during crushing. However, during the crushing of fiberglass reinforced plastics, the rotation of the cutter rollers causes fine debris and glass fiber filaments to splash, continuously impacting the baffles and causing them to oscillate back and forth. This dynamic oscillation creates intermittent openings between the baffle and the feed inlet wall, resulting in multiple serious consequences: First, glass fiber dust permeates the workshop, easily causing respiratory inflammation, allergies, and other illnesses for operators upon inhalation; long-term exposure may even lead to pulmonary fibrosis, seriously threatening occupational health. Second, the flying fiber filaments easily become entangled in external bearings, pulleys, and other rotating parts of the equipment, increasing wear and the frequency of malfunctions, and even causing equipment jamming and motor burnout, affecting production continuity and raising maintenance costs. Third, the splashing loss of valuable materials not only reduces resource recovery rates but also significantly weakens the mechanical properties of recycled materials due to uneven fiber content and disordered distribution, reducing product qualification rates and economic value. Therefore, effectively suppressing the splashing of debris and fibers during the crushing process is a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0004] In view of the problems of existing technology, such as the shielding curtain swinging and opening easily when the glass fiber plastic is broken, resulting in dust splashing, equipment failure and reduced resource recycling rate, a recycling and regeneration device for automotive injection molded parts waste is proposed.

[0005] The purpose is to: first, the waste material enters the conveying frame, and when the conveying frame moves, the inlet is closed and the outlet is opened to send the waste material into the crushing equipment, effectively preventing the fragments from splashing; at the same time, the airbag is inflated and blows air into the machine when the conveying frame is reset, preventing the fibers from escaping from the inlet.

[0006] The technical solution of this invention is a recycling and regeneration device for automotive injection molded parts waste, comprising a fiberglass crusher body, an extension trough fixedly connected inside the feed end of the fiberglass crusher body, a flat plate fixedly connected laterally inside the extension trough, a conveying frame slidably connected between the flat plate and the lower part of the extension trough, a baffle plate one hinged to the side of the conveying frame away from the feed end of the fiberglass crusher body, a baffle plate two hinged to the other side of the conveying frame, two guide rods fixedly connected to the side of the baffle plate two away from the baffle plate one, and an opening in the inner wall of the extension trough. The extension groove has a guide groove that matches the guide rod. Electric push rods are installed on both sides of the extension groove. When the electric push rods extend or retract, they drive the material conveying frame to slide. Two vertical plates are fixedly connected between the flat plate and the upper part of the extension groove. An air bag is fixedly installed on the side wall of one of the vertical plates. An air inlet pipe and an air outlet pipe are fixedly connected to one side of the air bag. The other end of the air inlet pipe extends through the extension groove to the outside. An air guide cover is fixedly connected to the air outlet pipe. The air guide cover is fixedly connected to the flat plate. Two pull ropes are connected between the other side of the air bag and the material conveying frame.

[0007] Furthermore, the material conveying frame includes two side plates with a right-angled trapezoidal structure, and a top plate is fixedly connected between the tops of the two side plates. The side plates are in sliding contact with the inner sidewall of the extension groove, and the top plate is in sliding contact with the bottom surface of the flat plate.

[0008] Furthermore, the guide rod has an L-shaped structure, the guide groove has a bent structure, and the guide rod is slidably disposed in the corresponding guide groove.

[0009] Furthermore, through holes are provided on both sides of the extension groove, and connecting ears that are fixedly connected to the side wall of the conveying frame are provided in the through holes. One end of the electric push rod is fixedly connected to the connecting ear.

[0010] Furthermore, one-way valves are fixedly installed on both the air inlet pipe and the air outlet pipe.

[0011] Furthermore, a cavity-structured air diffuser plate is fixedly connected to the side of the air outlet pipe near the second baffle. The air diffuser plate has multiple air diffuser holes on the side near the second baffle. Sealing caps are rotatably connected to both ends of the air outlet pipe. Two arc-shaped plates are connected between the two sealing caps. The arc-shaped plates slide in contact with the inner wall of the air outlet pipe. A toothed ring is fixedly connected to the sealing cap. A toothed rack is fixedly connected to the top surface of the material conveying frame at the position corresponding to the toothed ring.

[0012] Furthermore, two wire brackets are fixedly installed on the side wall of the vertical plate near one side of the baffle. The pull rope slides in contact with the wire brackets, and the wire brackets and the airbag are connected by an elastic element. A top block is fixedly connected to the sealing cover, and a positioning block is fixedly connected to the inner wall of the extension groove above the sealing cover. The positioning block has a right-angled trapezoidal structure, and a groove is opened on the top surface of the positioning block. A positioning ball is fixedly connected to the pull rope.

[0013] Furthermore, two deceleration plates are provided on one side of the positioning ball. The two deceleration plates are symmetrically arranged and have an F-shaped cross-section. The deceleration plates are provided with deceleration sliding surfaces adapted to the positioning ball. A base plate is fixedly connected between the bottoms of the two deceleration plates. The base plate is fixedly connected to the inner wall of the extension groove. A guide plate is hinged to the side of the deceleration plate facing the positioning ball. The lower end of the guide plate abuts against the base plate.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. The feeding frame, together with baffle one and baffle two, achieves intermittent sealed feeding, effectively suppressing the splashing of crushed material inside the crushing equipment. At the same time, the feeding frame moves and inflates the airbag. When the feeding frame returns, the airbag releases air and blows it towards the feeding frame, which can blow the crushed material in the feeding frame into the crushing equipment. This prevents the crushed material and fiber filaments inside the crushing equipment from escaping, thereby effectively improving the workshop working environment, reducing the risk of equipment failure, and improving the material recovery rate and the quality of recycled materials.

[0015] 2. The combination of the positioning block and the positioning ball enables the airbag to release air instantly, forming a high-pressure airflow that blows through the air guide hood to the conveyor frame, preventing material accumulation. It also forms an outward air curtain barrier at the moment of opening, improving the protection effect against dust and fiberglass flying backwards inside the crushing equipment.

[0016] 3. The air path of the air supply pipe can be switched. When the positioning ball moves in the deceleration sliding surface, the remaining gas in the air bag is slowly sprayed out through the air diffuser to form a continuous and stable air curtain, which creates a slight positive pressure in the crushing equipment, promotes the smooth falling of crushed powder, and avoids the accumulation of fiber flocs.

[0019] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0020] Example 1, referring to Figures 1-3 This is the first embodiment of the present invention, providing a recycling and regeneration device for automotive injection molded parts waste, including a fiberglass crusher body 1. An extension trough 2 is fixedly connected inside the feed end of the fiberglass crusher body 1. A flat plate 8 is horizontally fixedly connected inside the extension trough 2. A conveying frame 3 is slidably connected between the flat plate 8 and the lower part of the extension trough 2. A baffle 4 is hinged to the side of the conveying frame 3 away from the feed end of the fiberglass crusher body 1, and a second baffle 5 is hinged to the other side of the conveying frame 3. Two guide rods 6 are fixedly connected to the side of the second baffle 5 away from the first baffle 4. The inner wall of the extension trough 2 has openings for the guide rods. The guide groove 7 is adapted to the rod 6. Electric push rods 9 are installed on both sides of the extension groove 2. When the electric push rods 9 extend and retract, they drive the material conveying frame 3 to slide. Two vertical plates 15 are fixedly connected between the plate 8 and the upper part of the extension groove 2. An air bag 11 is fixedly installed on the side wall of one of the vertical plates 15. An air inlet pipe 12 and an air outlet pipe 13 are fixedly connected to one side of the air bag 11. The other end of the air inlet pipe 12 extends through the extension groove 2 to the outside. An air guide cover 14 is fixedly connected to the air outlet pipe 13. The air guide cover 14 is fixedly connected to the plate 8. Two pull ropes 16 are connected between the other side of the air bag 11 and the material conveying frame 3.

[0021] Specifically, during operation, the electric push rod 9 performs intermittent telescopic movements, driving the conveying frame 3 to slide back and forth along the length of the extension trough 2. The material to be crushed falls into the conveying frame 3 from the upper end of the extension trough 2. When the first baffle 4 moves to below the plate 8, the first baffle 4, the conveying frame 3, the second baffle 5, the plate 8, and the extension trough 2 together form a closed space, blocking the splash channel. Subsequently, with the cooperation of the guide rod 6 and the guide trough 7, the second baffle 5 rotates clockwise, and the waste material in the conveying frame 3 falls smoothly into the main body 1 of the fiberglass crusher to complete the crushing. During the downward movement of the conveying frame 3, the air bag 11 is stretched by the pull rope 16 and inflated through the air inlet pipe 12. When the conveying frame 3 returns, the air bag 11 is pressurized and deflates. The gas is sprayed out through the air outlet pipe 13 and the air guide cover 14, forming a positive pressure inside the conveying frame 3, blowing the residual fragments into the crushing chamber, while effectively suppressing the splashing of fiber dust and fragments from the feed inlet. This structure enables intermittent sealed feeding, preventing the escape of fragments and fibers from the source. This not only improves the workshop working environment and reduces the risk of equipment entanglement failure, but also enhances the material recovery rate and the quality of recycled materials.

[0022] Among them, reference Figure 2 The baffle 4 is arranged vertically. When the waste material is fed from the top of the extension trough 2 and slides down, it will naturally push the baffle 4 to rotate clockwise, so that the waste material can smoothly enter the inside of the conveying frame 3. After the waste material has completely fallen in, the baffle 4 will automatically rotate counterclockwise to reset under its own gravity, and re-close the feeding channel to prevent the crushed material from overflowing in the reverse direction during the subsequent crushing process.

[0023] Reference Figure 3 The material conveying frame 3 includes two side plates with a right-angled trapezoidal structure. A top plate is fixedly connected between the tops of the two side plates. The side plates slide in contact with the inner wall of the extension groove 2, and the top plate slides in contact with the bottom surface of the flat plate 8.

[0024] Specifically, the material conveying frame 3 is composed of two right-angled trapezoidal side plates and a top plate. The side plates slide tightly against the inner wall of the extension groove 2, and the top plate makes smooth contact with the bottom surface of the flat plate 8, which not only ensures smooth movement but also forms a reliable seal to prevent debris and fibers from overflowing from the gaps.

[0025] Reference Figure 2 The guide rod 6 has an L-shaped structure, and the guide groove 7 has a bent structure. The guide rod 6 is slidably set in the corresponding guide groove 7.

[0026] Specifically, the L-shaped guide rod 6 is slidably embedded in the corresponding bent guide groove 7, and the baffle 2 5 is precisely guided to flip open and close by the groove rail: when the guide rod 6 slides on the right side of the guide groove 7, it is limited by the groove body, and the baffle 2 5 is tightly attached to the port of the material conveying frame 3 to form a closed shield; when the guide rod 6 slides to the left side of the guide groove 7, it is forced to flip open clockwise by the guiding action of the inclined groove section.

[0027] Reference Figure 1 , Figure 3 The extension groove 2 has through holes on both sides, and a connecting ear 10 is provided in the through hole to be fixedly connected to the side wall of the conveying frame 3. One end of the electric push rod 9 is fixedly connected to the connecting ear 10.

[0028] Specifically, the telescopic end of the electric push rod 9 is fixedly connected to the connecting ear 10, and the cylinder end is fixed outside the extension groove 2. Through the telescopic movement of the electric push rod 9, the pushing and pulling forces are smoothly transmitted through the connecting ear 10, which reliably drives the material conveying frame 3 to reciprocate along the extension groove 2.

[0029] Among them, the two electric push rods 9 are controlled by the same signal to achieve synchronous telescopic movement, ensuring that the material conveying frame 3 moves smoothly back and forth and avoiding jamming or skew.

[0030] Reference Figure 7 One-way valves are fixedly installed on both the air inlet pipe 12 and the air outlet pipe 13.

[0031] Specifically, the one-way valves on the air inlet pipe 12 and the air outlet pipe 13 have opposite conduction directions. When inflating, outside air enters the air bladder 11 through the air inlet pipe 12, and when deflating, the air inside the air bladder 11 is discharged through the air outlet pipe 13. The gas is directionally sprayed into the material conveying frame 3 to avoid gas backflow and ensure a stable and reliable blowing and splash suppression effect.

[0032] Reference Figure 4 , Figure 5 , Figure 7 The air outlet pipe 13 is fixedly connected to a cavity-structured air diffuser plate 17 on the side near the baffle 5. The air diffuser plate 17 has multiple air diffuser holes on the side near the baffle 5. The two ends of the air outlet pipe 13 are rotatably connected to sealing caps 18. Two arc-shaped plates 19 are connected between the two sealing caps 18. The arc-shaped plates 19 slide in contact with the inner wall of the air outlet pipe 13. A toothed ring 20 is fixedly connected to the sealing cap 18. A toothed rack 21 is fixedly connected to the top surface of the material conveying frame 3 at the position corresponding to the toothed ring 20.

[0033] Specifically, one arc-shaped plate 19 is located at the connection between the air outlet pipe 13 and the air diffuser plate 17, and the other is located beside the connection between the air outlet pipe 13 and the air guide hood 14. When the conveyor frame 3 slides upward and is about to return to its original position, the rack 21 and the toothed ring 20 mesh and drive the sealing cover 18 and the arc-shaped plate 19 to rotate synchronously, switching the airflow path of the air outlet pipe 13 from the air guide hood 14 to the air diffuser plate 17. Subsequently, the residual gas in the airbag 11 is evenly and slowly sprayed out through the air diffuser hole, continuously forming a micro-positive pressure environment in the crushing chamber, effectively preventing the crushed material and glass fiber filaments from escaping from the feed inlet, while promoting the smooth fall of the crushed powder and avoiding the accumulation of fiber flocs.

[0034] Example 2, refer to Figure 4 , Figure 6This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that: two wire brackets 22 are fixedly installed on the side wall of the vertical plate 15 near the baffle 4. The pull rope 16 slides in contact with the wire brackets 22. The wire brackets 22 and the airbag 11 are connected by an elastic element 23. A top block 25 is fixedly connected to the sealing cover 18. A positioning block 24 is fixedly connected to the inner wall of the extension groove 2 above the sealing cover 18. The positioning block 24 has a right trapezoidal structure. A groove is opened on the top surface of the positioning block 24. A positioning ball 26 is fixedly connected to the pull rope 16.

[0035] Specifically, during the downward movement of the conveying frame 3, the airbag 11 is inflated by the pull rope 16, while the elastic element 23 is compressed and stores energy. As the pull rope 16 moves, it causes the positioning ball 26 to slide over the inclined surface of the positioning block 24 and abut against the side wall for positioning. When the rack 21 engages with the toothed ring 20 to drive the sealing cover 18 to rotate, the top block 25 rotates synchronously to one side of the positioning block 24, pushing the positioning ball 26 to disengage it from its limit position. At this time, the elastic element 23 and the airbag 11 are released instantaneously, forming an instantaneous high-pressure airflow in the conveying frame 3, which powerfully blows the internal fragments into the fiberglass crusher body 1. By combining elastic energy storage with instantaneous air pressure release, the feeding and purging force is improved, avoiding material residue, and an instantaneous positive pressure barrier is formed at the feed inlet, inhibiting the overflow of fiber filaments and dust from the source, significantly improving the cleanliness of the feeding and the stability of the equipment operation.

[0036] Understandably, at the instant the top block 25 contacts and pushes the positioning ball 26, the baffle 2 5 and the port of the conveying frame 3 form a slight opening angle. The high-pressure airflow established inside the conveying frame 3 can be ejected at high speed through this gap, forming a strong airflow to block and purge the feed channel. This design can not only use instantaneous high pressure to thoroughly blow away residual fragments and fiber filaments from the fiberglass crusher body 1, preventing material accumulation on the wall, but also form an outward air curtain barrier at the moment of opening, effectively preventing dust and fiberglass filaments inside the machine from splashing backward, further improving the sealing and dust suppression effect.

[0037] Reference Figure 8 Two speed reduction plates 27 are provided on one side of the positioning ball 26. The two speed reduction plates 27 are symmetrically arranged and have an F-shaped cross-section. The speed reduction plates 27 are provided with a speed reduction sliding surface 28 that is adapted to the positioning ball 26. A base plate 29 is fixedly connected between the bottoms of the two speed reduction plates 27. The base plate 29 is connected and fixed to the inner wall of the extension groove 2. A guide plate 30 is hinged to the side of the speed reduction plate 27 facing the positioning ball 26. The lower end of the guide plate 30 abuts against the base plate 29.

[0038] Specifically, when the pull rope 16 is pulled by the material conveying frame 3, the positioning ball 26 passes under the deceleration plate 27; when the elastic element 23 drives the pull rope 16 to reset, the positioning ball 26 slides upward along the guide plate 30 into the deceleration sliding surface 28. Relying on the sliding damping effect between the positioning ball 26 and the deceleration sliding surface 28, the pull rope 16 moves smoothly and slowly, thereby causing the airbag 11 to slowly rebound and reset. The internal gas is evenly and slowly sprayed out through the air diffuser hole, forming a continuous and stable air curtain, which continuously suppresses the escape of dust and fiber filaments.

[0039] The shape of the deceleration sliding surface 28 is adapted to the shape of the positioning ball 26, and the two slide in close contact to ensure stable and uniform damping and avoid excessively rapid or jerky airflow release. The rest of the structure is the same as that in Embodiment 1.

[0040] Based on embodiments 1-2, the working principle of this invention is as follows: The waste material to be crushed falls into the conveying frame 3. The electric push rod 9 drives the conveying frame 3 to slide along the extension groove 2, first sealing the feed inlet, then opening the baffle 5 through the guide rod 6 and guide groove 7, sending the waste material into the fiberglass crusher body 1. As the conveying frame 3 slides down, the pull rope 16 stretches the airbag 11 to inflate it, and the elastic element 23 compresses and stores force simultaneously. The positioning ball 26 slides past the positioning block 24 and abuts against the limit position. When the conveying frame 3 returns to its original position, the rack 21 engages with the toothed ring 20, causing the sealing cover 18 to rotate. The top block 25 pushes the positioning ball 26 away from the limit position, and the elastic element 23 and airbag 11 release instantaneously, forming a high-pressure airflow that blows away residual fragments from the conveying frame 3 through the air guide hood 14. Subsequently, the airflow path switches to the air diffuser plate 17, and the positioning ball 26 moves slowly along the deceleration surface 28, causing the airbag 11 to slowly exhaust air, forming a continuous air curtain through the air diffuser holes.

[0041] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
