Description

Technical Field

[0001] This invention belongs to the field of conveying device technology, and specifically discloses a conveying device with industrial visual inspection for foam plastic production. Background Technology

[0002] The production and processing of foamed plastic products generates a large amount of scrap, waste, and recycled materials. Among these, foam granules are a common form of waste, and their recycling is an important part of the production process. These foam granules typically need to be crushed and then transported by conveyor equipment to the next process for reuse.

[0003] Currently, screw conveyors are widely used in the industry to transport waste solid foam granules. They are widely applied in many bulk material handling fields. However, in practical applications, traditional screw conveyors have revealed significant shortcomings when handling lightweight materials derived from foam granules. Because the particles formed after the foam granules are crushed are lightweight and large, they easily generate large amounts of dust and particulate matter under the pushing and stirring action of the screw blades. These flying foam fragments not only pollute the production environment, leading to a messy and difficult-to-clean work site, but also result in the loss and waste of materials processed from the foam granules. More importantly, the fine foam particles floating in the air create a dust hazard, posing a potential threat to the occupational health of operators.

[0004] To address the dust leakage problem during the conveying of foam granule boards, some existing technologies have installed openable flaps above the conveyor walls, attempting to suppress dust through physical shielding. However, this design has significant limitations: First, the flaps are often of fixed specifications, making it difficult to adapt to conveying equipment or installation stations of different sizes and structures, resulting in poor versatility and ineffective application on various types of equipment. Second, gaps inevitably exist between the flaps and the walls, as well as at the joints between adjacent flaps. When the internal pressure changes or the material is agitated, extremely lightweight particles from broken foam granule boards can still escape through these tiny gaps, failing to achieve the desired dust suppression effect. Therefore, existing suppression methods cannot fundamentally solve the problem of particle scattering during the conveying process of foam granule boards.

[0005] In summary, designing a conveying device that can effectively suppress the flying of lightweight particles from broken foam particleboard during screw conveying, maintain a clean on-site environment, and possess good adaptability and sealing performance is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0006] The purpose of this invention is to solve the problems existing in the background art, and to propose a conveying device with industrial visual inspection for foam plastic production, including a hopper, a hopper, a spiral conveyor auger, and a visual inspection sensor. The spiral conveyor auger is located at one end inside the hopper. The hopper is connected and installed above the hopper. A discharge hopper is connected and installed below the end of the hopper away from the discharge hopper. An installation frame is provided on the outside of the hopper side near the discharge hopper. A transparent thickened cover film is connected to the installation frame through an internal winding mechanism. One end of the transparent thickened cover film covers the outside of the hopper. Installation components are provided on the lower outside of both ends of the installation frame. Guide rods are fixedly installed on the outside of each installation component. Two sets of film sealing mechanisms are symmetrically arranged on the outside of the two guide rods. The two sets of film sealing mechanisms include slides that slide on one end of the guide rods respectively. T-shaped cover plates are pressed against the two sets of slides by corresponding elastic elements. Side wall fasteners are provided on the inside of the sides of the two sets of slides that are close to each other.

[0007] In the above technical solution, the mounting assembly further includes a mounting plate, which is connected to the mounting bracket by bolts threaded at each of the internal corners, and one end of the guide rod is fixed to the outside of the mounting plate.

[0008] In the above technical solution, the elastic element further includes a guide post, which is vertically installed on the top of the slide. A spring is sleeved on the upper part of the guide post. The guide post is slidably connected to the T-shaped cover plate. The two ends of the spring are respectively connected to the outer surfaces of the guide post and the T-shaped cover plate that are close to each other.

[0009] In the above technical solution, the sidewall fastening component further includes a screw, one end of which is threaded through the inside of the slide, and an abutment block is slidably installed on the outside of the end of the slide away from the guide post. A retaining sleeve is fixedly installed on the outside of the end of the abutment block near the screw, and one end of the screw is rotatably locked inside the retaining sleeve.

[0010] In the above technical solution, the sidewall fastening component further includes a retainer fixedly installed on the outer wall of two abutting blocks on the same side. Each retainer has a retainer head slidably fitted inside, and the two retainers are connected by a fixed elastic band.

[0011] In the above technical solution, one of the T-shaped cover plates is further provided with a mounting base in the middle of the outer side, and an air pump is fixedly installed on the outside of the mounting base. The visual detection sensor is installed on the front end of the mounting base.

[0012] In the above technical solution, a telescopic hose is further connected to one end of the air pump, and a blowing component is provided at the end of the telescopic hose away from the air pump.

[0013] In the above technical solution, the blowing component further includes a nozzle connected to the end of the telescopic hose away from the air pump. The nozzle has multiple vent holes symmetrically opened on its exterior. The multiple vent holes are arranged vertically. A storage strap is provided on the exterior of the two sets of T-shaped cover plates that are close to each other. The upper surface of the storage strap has a channel for mounting the nozzle.

[0014] In the above technical solution, the winding mechanism further includes a motor and a reel. The motor is fixedly mounted on one side of the outer wall of the mounting frame. A flange joint is fixedly mounted on the output end of the motor. One end of the reel is connected to the flange joint through multiple fixing bolts. A clamping cylinder is fixedly mounted on the end of the mounting frame away from the motor. One end of the reel is rotatably inserted into the clamping cylinder.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. By setting up a transparent thickened cover film in conjunction with a winding mechanism, the present invention can flexibly adjust the covering length according to the actual length of the cabin or the installation requirements of different equipment, which significantly improves the versatility and adaptability of the device and solves the problem that the traditional flip cover has fixed specifications and is difficult to match with different equipment.

[0016] 2. This invention, by setting up a tight-film sealing mechanism, utilizes the synergistic effect of the slide, elastic element, and T-shaped cover plate to ensure that the transparent thickened cover film can be tightly adhered to the outside of the cabin. At the same time, under the action of the side wall fastener, the gaps between the cover film and the cabin wall are further eliminated, achieving multi-directional and gapless sealing of the cabin. This effectively inhibits the escape of lightweight foam particles from gaps during transportation, significantly reduces dust leakage, maintains a clean production environment, reduces material waste, and reduces potential threats to the health of operators.

[0017] 3. The present invention, through the elastic band and clamping head structure in the side wall fastening component, can form a continuous tightening force between the two side abutment blocks, so that the side of the transparent thickened cover film is always tightly fitted to the side wall of the cabin, avoiding the cover film from loosening due to equipment vibration or material flow, and further improving the reliability and stability of the seal.

[0018] 4. By setting up a visual inspection sensor and an air pump blowing mechanism, this invention can monitor the material status in real time during the conveying process. When necessary, the nozzle can be extended into the cabin to blow away the adhering foam particles on the surface near the transparent thickened cover film. This allows for timely detection of the conveying status of the spiral conveyor auger inside the cabin, improving the smoothness and automation of the conveying process. At the same time, the visual inspection function provides data support for subsequent quality control. Attached Figure Description

[0021] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the invention is not limited to the specific embodiments disclosed below.

[0023] like Figures 1-8The conveying device for foam plastic production with industrial vision inspection includes a through chamber 1, a hopper 2, a screw conveyor 3, and a vision inspection sensor 30. The screw conveyor 3 is located at one end inside the through chamber 1. The hopper 2 is connected and installed above the through chamber 1. A discharge hopper 26 is connected and installed below the end of the through chamber 1 away from the hopper 2. An installation frame 4 is provided on the outside of the side of the through chamber 1 near the discharge hopper 26. A transparent thickened cover film 7 is connected to the installation frame 4 through an internal winding mechanism. One end of the transparent thickened cover film 7 covers the outside of the through chamber 1. Installation components are provided on the lower outside of both ends of the installation frame 4. Guide rods 10 are fixedly installed on the outside of the installation components. Two sets of tight film sealing mechanisms are symmetrically arranged on the outside of the two guide rods 10. The two sets of tight film sealing mechanisms include slides 11 that slide on one end of the guide rods 10 respectively. T-shaped cover plates 6 are pressed against the two sets of slides 11 through corresponding elastic elements. Side wall fastening members are provided on the inside of the side of the two sets of slides 11 that are close to each other. In this embodiment, a partially transparent thickened cover film 7 is covered to the outside of the passageway 1 by a winding mechanism, and a tight seal is achieved using two sets of film-sealing mechanisms. Specifically, the guide rods 10 at both ends of the mounting frame 4 provide sliding guidance for the slide 11, which can move on the guide rods 10 to adapt to passageways 1 of different widths. The elastic element above the slide 11 applies downward pressure to the T-shaped cover plate 6, causing the T-shaped cover plate 6 to press against the upper surface of the transparent thickened cover film 7, thereby pressing the cover film tightly against the outer wall of the passageway 1. At the same time, the side wall fastener on the inner side of the slide 11 further acts on the side of the transparent thickened cover film 7, eliminating the gap between the transparent thickened cover film 7 and the passageway wall. Thus, the transparent thickened cover film 7 can flexibly adjust its coverage area according to the length of the passageway 1, and achieve all-round sealing through multi-point pressing, effectively preventing lightweight foam particles from escaping from the gaps, maintaining a clean production environment, reducing material waste, and providing a clear field of view for subsequent visual inspection.

[0024] The mounting assembly includes a mounting plate 13, which is connected to the mounting bracket 4 by bolts 17 threaded at each of the internal corners. One end of the guide rod 10 is fixed to the outside of the mounting plate 13. In this embodiment, the mounting assembly uses a combination of mounting plate 13 and bolts 17, which allows the guide rod 10 to be securely fixed to the mounting frame 4. The bolts 17 are distributed at various corners of the mounting plate 13, ensuring multi-point force distribution and improving the overall structural stability and vibration resistance. During long-term operation, this connection method can withstand equipment vibration and membrane tension, preventing the guide rod 10 from loosening or shifting, thereby ensuring smooth movement of the slide 11, uniform sealing pressure, and enhancing the reliability of the membrane sealing mechanism.

[0025] The elastic element includes a guide post 14, which is vertically installed on the top of the slide 11. A spring 18 is sleeved on the upper part of the guide post 14. The guide post 14 is slidably connected to the T-shaped cover plate 6. The two ends of the spring 18 are respectively connected to the outer surfaces of the guide post 14 and the T-shaped cover plate 6 that are close to each other. In this embodiment, the elastic element employs a combination of guide post 14 and spring 18 to achieve elastic compression of the T-shaped cover plate 6 onto the transparent thickened cover film 7. The guide post 14 is vertically fixed to the top of the slide 11. The T-shaped cover plate 6 is fitted onto the guide post 14 and can slide up and down. The spring 18 is fitted onto the upper end of the guide post 14 and is positioned between the guide post 14 and the T-shaped cover plate 6, consistently applying a downward elastic force to the T-shaped cover plate 6. When the transparent thickened cover film 7 is laid on the passageway 1, the T-shaped cover plate 6 adheres tightly to the surface of the transparent thickened cover film 7 under the action of the elastic force. Even if there are minor unevennesses on the outer wall of the passageway 1 or changes in the thickness of the cover film, the spring 18 can automatically compensate for displacement, ensuring a continuously stable compression force. This elastic compression method avoids damage to the transparent thickened cover film 7 that may be caused by rigid compression, while maintaining a good sealing effect.

[0026] The sidewall fastener includes a screw 16, one end of which is threaded through the inside of the slide 11. A stop block 19 is slidably installed on the outside of the end of the slide 11 away from the guide post 14. A sleeve 20 is fixedly installed on the outside of the end of the stop block 19 near the screw 16. One end of the screw 16 is rotated and locked inside the sleeve 20. In this embodiment, the sidewall fastening component, through the cooperation of the screw 16 and the abutment block 19, allows the abutment block 19 to move towards the sidewall of the passage chamber 1, pressing the side of the transparent thickened cover film 7 tightly against the chamber wall. Specifically, the operator rotates the screw 16. Since the screw 16 is threadedly connected to the slide 11, the rotation of the screw 16 is converted into axial displacement, pushing the retainer 20 and the abutment block 19 to slide along the slide 11 until the abutment block 19 is in close contact with the side of the transparent thickened cover film 7. The design of the retainer 20 allows the end of the screw 16 to rotate freely inside it, avoiding the jamming phenomenon that occurs when the screw 16 directly drives the abutment block 19. This adjustment method can precisely adjust the clamping force according to the actual position of the sidewall of the passage chamber 1, effectively eliminating gaps on the side of the transparent thickened cover film 7, preventing particles from escaping from the side, and is simple to operate and highly adaptable.

[0027] The side wall fastening component includes a retainer 23 fixedly installed on the outer wall of two abutment blocks 19 on the same side. Each retainer 23 has a retainer head 22 slidably fitted inside. The two retainers 22 are connected by an elastic band 21 that is fixedly connected. In this embodiment, an elastic band 21 is added between the two abutment blocks 19 to further enhance the continuity and uniformity of the sidewall seal. The retaining shell 23 is fixed to the outer wall of the abutment block 19, and the retaining head 22 can slide inside the retaining shell 23. The elastic band 21 connects the two retaining heads 22. When the abutment block 19 presses against the side of the transparent thickened cover film 7, the elastic band 21 is in a stretched state. Thus, the side of the transparent thickened cover film 7 between the two sets of slides 11 can be limited by the elastic band 21.

[0028] One set of T-shaped cover plates 6 has an external middle fixed frame with a mounting base 8. An air pump 15 is fixedly installed on the outside of the mounting base 8, and a vision detection sensor 30 is installed on the front end of the mounting base 8. In this embodiment, by setting a mounting base 8 on the T-shaped cover plate 6, the air pump 15 and the vision inspection sensor 30 are integrated on one end of the T-shaped cover plate 6, realizing real-time monitoring and active intervention of the conveying process. The vision inspection sensor 30 is located at the front end of the mounting base 8, facing the inside of the passage 1, and can continuously collect material flow images or identify abnormal accumulation conditions. It is connected to an external PLC device through an external wire; the air pump 15 provides a compressed air source for subsequent purging actions.

[0029] Therefore, this layout saves space and ensures the stability of the detection angle, avoiding focus shift caused by vibration. When the vision inspection sensor 30 detects material blockage or foam particles adhering to the surface of the transparent thickened cover film 7, the external PLC device can promptly start the air pump 15 for cleaning, thereby ensuring smooth conveying and accurate vision inspection.

[0030] One end of the air pump 15 is connected to a telescopic hose 9, and a blowing component is provided at the end of the telescopic hose 9 away from the air pump 15. In this embodiment, the telescopic hose 9 connects the air pump 15 to the blowing component, achieving both airflow delivery and allowing the blowing component to move within a certain range to align with the area requiring cleaning. In non-operating mode, the blowing component can be retracted into a specific location without obstructing the sealing of the cover membrane; when cleaning is required, the blowing component can be extended to the target area manually or automatically. This design makes cleaning operations flexible and convenient, especially suitable for long-distance transport or situations with severe localized material accumulation, ensuring that the visual inspection area remains clear at all times.

[0031] The blowing component includes a nozzle 24 connected to the end of the telescopic hose 9 away from the air pump 15. Multiple air holes 25 are symmetrically opened on the outside of the nozzle 24. The multiple air holes 25 are arranged vertically. A storage strap 12 is provided on the outside of the side of the two sets of T-shaped cover plates 6 that are close to each other. The upper surface of the storage strap 12 has a channel for clamping the nozzle 24. In this embodiment, the nozzle 24 serves as a blowing component, with multiple vertical ventilation holes 25 on its outer wall, enabling multi-angle and multi-height airflow jets to cover a wide area of ​​the inner surface of the transparent thickened cover film 7 or the surface of the material, effectively removing adhering substances. A storage strap 12 is positioned between the T-shaped cover plates 6, with channels on its upper surface used to hold the nozzle 24 in place. When the nozzle 24 is inserted into the transparent thickened cover film 7, the storage strap 12 can block external airflow interference. It should be noted that the transparent thickened cover film 7 can automatically make a hole from the top surface when the nozzle 24 is installed.

[0032] The winding mechanism includes a motor 5 and a reel 28. The motor 5 is fixedly mounted on one side of the outer wall of the mounting frame 4. A flange joint 27 is fixedly mounted on the output end of the motor 5. One end of the reel 28 is connected to the flange joint 27 through multiple fixing bolts. A clamp 29 is fixedly mounted on the end of the mounting frame 4 away from the motor 5. One end of the reel 28 is rotated and inserted into the clamp 29. In this embodiment, the motor 5 is rigidly connected to the reel 28 via a flange joint 27, and multiple fixing bolts ensure the reliability of torque transmission. The other end of the reel 28 is inserted into the retainer 29, allowing it to rotate freely and providing stable support. When it is necessary to adjust the coverage length or replace the transparent thickened cover film 7, starting the motor 5 in both forward and reverse directions will complete the winding or unwinding operation, significantly reducing the intensity of manual operation. This electric winding method is responsive and precise, and can quickly adjust the coverage area of ​​the transparent thickened cover film 7 according to different working conditions, significantly improving the automation level and adaptability of the device.

[0033] Working principle: Foamed plastic granules enter the passage chamber 1 through the hopper 2. Driven by the rotation of the screw conveyor 3, they move along the axial direction of the passage chamber 1 and are finally discharged through the discharge hopper 26, completing the conveying process. During the conveying process, to prevent the lightweight foamed granules from flying away, the outside of the passage chamber 1 is covered with a transparent thickened cover film 7. One end of the transparent thickened cover film 7 is connected to a winding mechanism. According to the actual length of the passage chamber 1 or the equipment installation requirements, the winding and unwinding of the cover film can be adjusted by driving the roller 28 through the motor 5, ensuring that its coverage range can adapt to different equipment specifications. After the transparent thickened cover film 7 is applied, a tight fit is achieved through two sets of film-tightening sealing mechanisms. The slide 11 slides along the guide rod 10, causing the T-shaped cover plate 6 to press down on the cover film under the action of the elastic element. The two sets of T-shaped cover plates 6 are specifically positioned at one end near the roller 28 and the other end at one end of the hopper 2, so that the transparent thickened cover film 7 is tightly attached to the outer wall of the through-cabin 1. At the same time, the side wall fastening component drives the abutment block 19 to approach the side wall of the through-cabin 1 through the screw 16, pressing down on the side walls of the transparent thickened cover film 7 that overlaps on both sides of the outside of the through-cabin 1, and maintaining continuous tightening through the elastic band 21 and the clamp 22 structure, eliminating gaps between the cover film and the cabin wall, and ensuring all-round sealing. During the conveying process, the visual inspection sensor 30 monitors the material status inside the passage chamber 1 and the operation of the screw conveyor 3 in real time. When material accumulation or foam particles adhering to the surface of the cover film are detected, the air pump 15 is started, and airflow is delivered to the nozzle 24 through the telescopic hose 9. The nozzle 24 extends along the receiving belt 12 into the passage chamber 1 and blows the surface of the transparent thickened cover film 7 or the material through multiple air holes 25 to remove the adhering substances, ensuring the accuracy of visual inspection and the smoothness of the conveying process.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
