Description

Technical Field

[0001] This utility model relates to the field of waste recycling equipment, and in particular to a waste recycling equipment for door and window profiles. Background Technology

[0002] Polyurethane fiberglass, with its excellent mechanical strength, weather resistance, anti-aging properties, and corrosion resistance, has become one of the core materials in modern door and window profile production. It is widely used in key components such as frame reinforcement and sealing structures of aluminum alloy and PVC doors and windows, effectively improving the structural stability and service life of these products. However, with the large-scale and automated development of the door and window manufacturing industry, a large amount of polyurethane fiberglass waste is generated during the cutting, drilling, and assembly processes of door and window profiles. This waste has a high density and varies in volume; direct disposal not only wastes valuable non-metallic resources but may also impose a long-term burden on the soil and environment due to its difficulty in natural degradation.

[0003] Existing recycling equipment's storage bins only serve as temporary containers for crushed materials and lack dedicated automated feeding mechanisms. Some equipment relies on gravity to discharge materials, i.e., by tilting the storage bin to allow the material to slide naturally towards the discharge port. However, after polyurethane fiberglass is crushed, the particle size is uneven, which easily leads to accumulation and blockage at the bottom or corners of the storage bin, causing interruptions in discharge and requiring frequent manual unblocking. This not only increases the labor intensity of operators but also seriously affects the continuous efficiency of waste recycling. In response to this technical problem, this application proposes a waste recycling device for door and window profiles. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a waste recycling device for door and window profiles. An electric push rod can provide a stable thrust to drive the push plate to move. A guide rod can limit the movement trajectory of the push plate to prevent it from tilting or getting stuck. After the crushed material is temporarily stored in the storage box, the electric push rod can push the push plate to smoothly push the material to the discharge chute, realizing the automatic batch discharge of crushed material and effectively avoiding the accumulation and blockage of material in the storage box.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A waste recycling device for door and window profiles includes a crushing box. Crushing roller one and crushing roller two are connected to the front end of the crushing box via a drive assembly. A feeding trough is fixedly connected to the top of the crushing box. Two rotating rods are rotatably connected to the inner wall of the feeding trough. Baffles are fixedly connected to the middle of the outer walls of the two rotating rods. Reset assemblies are provided at both ends of the outer walls of the two rotating rods. A funnel is fixedly connected to the top of the feeding trough. A storage box is fixedly connected to the bottom of the crushing box. An electric push rod is fixedly connected to the left side of the inner wall of the storage box. A push plate is fixedly connected to the right end of the electric push rod. The outer wall of the push plate is slidably connected to the inner wall of the storage box.

[0006] Furthermore, the drive assembly includes a motor mounted on a fixed frame at the front end of the crushing box. The drive end of the motor is fixedly connected to the front end of the first crushing roller. The drive end of the motor is connected to a first gear via a synchronous belt. The rear end of the first gear is rotatably connected to the front end of the crushing box. A second gear is meshed with the right side of the outer wall of the first gear. The rear end of the second gear is rotatably connected to the front end of the second crushing roller.

[0007] Furthermore, the reset assembly includes torsion springs located at both ends of the outer walls of the two rotating rods. Fixed plates are fixedly connected to both ends of the two rotating rods. One end of each of the multiple torsion springs is connected to the feed chute, and the other end of each of the multiple torsion springs is connected to multiple fixed plates respectively.

[0008] Furthermore, rubber pads are fixedly connected to both the front and rear sides of the inner wall of the feed trough, and the bottom ends of the two rubber pads are respectively set at the top of the two baffles.

[0009] Furthermore, two symmetrically arranged guide plates are fixedly connected to the top side of the inner wall of the crushing box.

[0010] Furthermore, a guide plate is fixedly connected to the bottom side of the inner wall of the crushing box.

[0011] Furthermore, guide rods are fixedly connected to both the front and rear sides of the inner wall of the storage box, and the outer walls of the two guide rods are slidably connected to the inner wall of the push plate.

[0012] Furthermore, a discharge chute is fixedly connected to the right end of the storage box.

[0013] This utility model has the following beneficial effects: 1. In this utility model, the electric push rod can provide a stable thrust to drive the push plate to move. The guide rod can limit the movement trajectory of the push plate to prevent it from tilting and jamming. After the crushed material is temporarily stored in the storage box, the electric push rod can push the push plate to push the material smoothly to the discharge chute, realizing the automatic batch discharge of crushed material, effectively avoiding the accumulation and blockage of material in the storage box, reducing manual cleaning intervention, and significantly improving the continuity of waste recycling and discharge efficiency.

[0014] 2. In this utility model, when the material is fed, the baffle can be pushed to open and close around the rotating rod. After the feeding is completed, the torsion spring can drive the baffle to automatically reset and close. At the same time, the rubber pad can tightly fit the top of the baffle, sealing the gap between the baffle and the feed chute, preventing the debris generated by the crushing rollers 1 and 2 from flying out of the feed inlet. This protects the operator from accidental injury by debris and prevents the debris from spreading and polluting the operating environment. Attached Figure Description

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Reference Figure 1 , Figure 2 and Figure 5 An embodiment of this utility model provides a waste recycling device for door and window profiles, including a crushing box 1. The front end of the crushing box 1 is connected to a crushing roller 6 and a crushing roller 7 via a motor 2, a synchronous belt 3, a gear 1 4 and a gear 2 5. The top of the crushing box 1 is fixedly connected to a feeding trough 10. The inner wall of the feeding trough 10 is rotatably connected to two rotating rods 12. The middle of the outer wall of each of the two rotating rods 12 is fixedly connected to a baffle 13. Both ends of the outer wall of each of the two rotating rods 12 are provided with a torsion spring 14 and a fixing plate 15. The top of the feeding trough 10 is fixedly connected to a funnel 16. The bottom of the crushing box 1 is fixedly connected to a storage box 17. The left side of the inner wall of the storage box 17 is fixedly connected to an electric push rod 18. The right end of the electric push rod 18 is fixedly connected to a push plate 19. The outer wall of the push plate 19 is slidably connected to the inner wall of the storage box 17. Specifically, the crushing box 1, as the core frame of the equipment, provides installation support for crushing roller 6, crushing roller 7, and various guide structures, ensuring the overall structural stability. The motor 2 is the power output source, providing power for the rotation of crushing roller 6 and crushing roller 7. The synchronous belt 3 transmits power synchronously, transferring the driving force of the motor 2 to gear 4, ensuring that gear 4 rotates in the same direction as crushing roller 6. Gear 4 and gear 5 mesh together to convert power into reverse transmission, causing crushing roller 7 to rotate in the opposite direction to crushing roller 6, creating a squeezing, shearing, and crushing effect on the door and window profile waste. The rotating rod 12 provides a fulcrum for the baffle 13, allowing the baffle to rotate... 13 can be opened and closed flexibly. The torsion spring 14 and the fixed plate 15 form a reset assembly. The fixed plate 15 is fixed at both ends of the rotating rod 12. The elastic force of the torsion spring 14 can drive the rotating rod 12 to reset after the baffle 13 is opened and closed, so as to realize the automatic closure of the baffle 13. The funnel 16 expands the feed port area to facilitate the operator to put waste materials in batches and reduce the spillage of waste materials during the feeding process. The storage box 17 is used to temporarily store the crushed waste materials to avoid the direct scattering of crushed materials and realize batch collection. The electric push rod 18 serves as the power source for pushing materials and can drive the push plate 19 to slide along the inner wall of the storage box 17. The push plate 19 pushes the crushed materials in the storage box 17 to the discharge end by sliding, thus completing the material transfer.

[0019] Reference Figure 1 , Figure 3 and Figure 4 The motor 2, mounted on a fixed frame at the front end of the crushing box 1, has its drive end fixedly connected to the front end of the crushing roller 6. The drive end of the motor 2 is connected to a gear 4 via a synchronous belt 3. The rear end of gear 4 is rotatably connected to the front end of the crushing box 1. A gear 5 is meshed on the right side of the outer wall of gear 4. The rear end of gear 5 is rotatably connected to the front end of the crushing roller 7. Torsion springs 14 are located at both ends of the outer walls of the two rotating rods 12. Fixed plates 15 are fixedly connected to both ends of the two rotating rods 12. One end of each torsion spring 14 is connected to the feed chute 10. Multiple torsion springs 14 are connected at their other ends to multiple fixed plates 15 respectively. Rubber pads 11 are fixedly connected to both the front and rear sides of the inner wall of the feed trough 10. The bottom ends of the two rubber pads 11 are respectively set at the top of the two baffles 13. Two symmetrically arranged guide plates 8 are fixedly connected to the top side of the inner wall of the crushing box 1. A guide plate 9 is fixedly connected to the bottom side of the inner wall of the crushing box 1. Guide rods 20 are fixedly connected to both the front and rear sides of the inner wall of the storage box 17. The outer walls of the two guide rods 20 are slidably connected to the inner wall of the push plate 19. A discharge trough 21 is fixedly connected to the right end of the storage box 17. Specifically, the rubber pad 11 can limit the reset position of the baffle 13 to prevent it from rotating too far due to the excessive elasticity of the torsion spring 14. On the other hand, it can reduce the noise generated when the baffle 13 resets. The guide plate 8 is symmetrically inclined, which can accurately guide the waste falling from the feed chute 10 to the meshing area of ​​the crushing roller 6 and the crushing roller 7, avoiding the waste from deviating and causing insufficient crushing or getting stuck on the inner wall of the crushing box 1. The guide plate 9 is inclined downward, which can quickly guide the crushed waste into the storage box 17, preventing the crushed material from accumulating at the bottom of the crushing box 1 and ensuring the continuous crushing process. The guide rod 20 slides with the push plate 19, which can limit the movement trajectory of the push plate 19 and prevent the push plate 19 from tilting or getting stuck during sliding. At the same time, it reduces the radial force on the electric push rod 18 and extends the service life of the electric push rod 18. The discharge chute 21 serves as a material output channel, which can directionally discharge the crushed material pushed by the push plate 19, making it convenient for subsequent collection of the crushed material and preventing the material from scattering during discharge.

[0020] Working principle: First, complete the power-on check of the equipment, then start motor 2. Its drive end directly drives crushing roller 6 to rotate clockwise. At the same time, through synchronous belt 3, it drives gear 4 to rotate in the same direction as crushing roller 6. Gear 4 meshes with gear 5, which in turn drives gear 5 and the connected crushing roller 7 to rotate counterclockwise, so that the two crushing rollers form a crushing state of opposite rotation. Then, the operator puts the waste to be recycled into the funnel 16. After the waste enters the feed trough 10, it gently pushes down the baffle 13, causing it to rotate around the rotating rod 12 and torsion spring 14 through the fixed plate 15. After fully entering, the torsion spring 14 resets and drives the baffle 13 to close. The rubber pad 11 in the feed trough 10 restricts the baffle 13 from over-resetting and seals the gap to prevent debris from flying out. The waste entering the crushing box 1 is accurately dropped between the two crushing rollers under the guidance of the guide plate 8 to complete the crushing. After crushing, the material slides into the storage box 17 for temporary storage via the guide plate 9. When the material accumulates to a certain amount, the electric push rod 18 is activated to push the push plate 19. The push plate 19 slides smoothly under the limit of the guide rod 20, pushing the material to the discharge trough 21 at the right end of the storage box 17 for discharge, completing one waste recycling crushing process.
