Description

Technical Field

[0001] This utility model belongs to the field of honeycomb panel coating and pressing technology, specifically, it relates to a residual adhesive recovery device for honeycomb panel coating and pressing. Background Technology

[0002] Honeycomb panels, as a lightweight and high-strength composite material structure, are widely used in aerospace, architectural decoration, packaging, and transportation. The adhesive coating and pressing process is a crucial step in their manufacturing. This process requires uniformly coating the honeycomb core material with adhesive before hot-pressing it with the panel. During the adhesive coating process, to ensure sufficient wetting and uniform coating, an appropriate excess of adhesive is usually applied. This results in some excess adhesive being squeezed out from the edges of the honeycomb panel during the pressing stage, forming residual adhesive. Traditionally, production sites address this issue by placing simple drip trays or laying absorbent paper under the pressing equipment. However, drip trays lack drainage and collection structures, causing residual adhesive to scatter throughout the tray. Cleaning requires repeated manual scraping with a scraper, which is time-consuming, labor-intensive, and difficult to thoroughly clean. Absorbent paper, on the other hand, prevents the absorption of adhesive, increasing raw material costs. Some manufacturers have attempted to use metal trays with drainage holes, but due to the flat inner surface of the trays and the lack of guiding structures, residual adhesive has poor flowability and easily accumulates and solidifies at the edges and corners, creating cleaning dead zones. Furthermore, the trays require regular disassembly and cleaning, disrupting production schedules. With increasingly stringent environmental requirements and rising cost control demands, how to efficiently recover residual adhesive during the lamination and pressing process, reduce adhesive waste, lower cleaning difficulty, and maintain a clean production environment has become a pressing practical problem for the honeycomb panel manufacturing industry. Utility Model Content

[0003] In view of this, the present invention provides a residual adhesive recovery device for honeycomb panel coating and pressing molding. This device can solve the problem that residual adhesive generated during the existing honeycomb panel coating and pressing molding process often drips or flows directly onto the ground or work surface, causing adhesive waste and polluting the working environment. Cleaning is difficult and labor-intensive. At the same time, the scattered residual adhesive is easy to solidify and form waste, increasing the treatment cost. Existing simple liquid receiving containers cannot effectively guide and collect residual adhesive, and there is a lack of means to clean the residual adhesive on the inner wall of the container. This results in low recycling efficiency and the need for frequent replacement or cleaning of the container, which affects the continuity of production and economic benefits.

[0004] This utility model is implemented as follows:

[0005] This utility model provides a residual adhesive recovery device for honeycomb panel coating and pressing molding, comprising a recovery chamber, a guide plate, and a scraping assembly. The recovery chamber has a rectangular trough structure, and a sunken liquid collection pit is provided in the central area of ​​the bottom of the recovery chamber. The depth of the liquid collection pit is 1 / 3 to 1 / 2 of the total height of the recovery chamber. One end of the guide plate is connected to the upper part of the inner side wall of the recovery chamber through a hinge shaft, and the other end of the guide plate is a free end that extends into the internal space of the recovery chamber. The guide plate is arc-shaped with its arc surface facing the liquid collection pit. The scraping assembly includes a scraping plate and a drive rod. The scraping plate has a trapezoidal flat plate structure, and the length of the upper bottom edge of the scraping plate is less than the length of the lower bottom edge. One end of the drive rod is fixedly connected to the geometric center of the scraping plate, and the other end of the drive rod passes through a sliding hole opened on the side wall of the recovery chamber and extends to the outside of the recovery chamber. The sliding hole is elongated and its long axis is parallel to the bottom surface of the recovery chamber.

[0006] The technical advantages of the residual adhesive recovery device for honeycomb panel coating and pressing provided by this utility model are as follows: By setting up a cooperative structure of three main components—a recovery chamber, a guide plate, and a scraping component—the device achieves efficient recovery of residual adhesive generated during the honeycomb panel coating and pressing process. The rectangular trough structure of the recovery chamber, combined with a sunken collection pit, can accommodate and collect residual adhesive. The guide plate is connected by a hinge shaft, allowing for angle adjustment and guiding the residual adhesive to the collection pit with an arc-shaped surface. The scraping component, with a trapezoidal scraping plate and a sliding drive rod, removes residual adhesive from the inner wall of the chamber. The overall structure is simple, and the connection between the components is clear, facilitating installation and maintenance. At the same time, the depth of the collection pit allows the residual adhesive to settle and concentrate fully, improving the recovery efficiency.

[0007] Based on the above technical solution, the residual adhesive recovery device for honeycomb panel coating and pressing molding of this utility model can be further improved as follows:

[0008] The radius of curvature of the arc-shaped surface of the guide plate is 1 / 2 to 3 / 5 of the width of the recovery cavity.

[0009] The beneficial effects of adopting the above-mentioned improved scheme are as follows: by limiting the ratio between the radius of curvature of the arc surface of the guide plate and the width of the inside of the recovery cavity, the guide plate can form a suitable guiding angle and flow channel space. When the residual glue flows on the arc surface of the guide plate, it can maintain a stable laminar flow state and avoid splashing or eddy phenomena. At the same time, the range of the radius of curvature ensures that the guide plate will not occupy too much cavity space due to excessive curvature, nor will it have poor guiding effect due to excessive curvature. Thus, the residual glue is transported smoothly and efficiently from the glue application position to the collection pit.

[0010] Furthermore, the hinge axis at the connection between the guide plate and the inner wall of the recovery chamber is higher than the bottom surface of the collection pit, and the vertical distance between the end of the guide plate and the bottom surface of the collection pit when the free end of the guide plate is in a natural drooping state is 1 / 4 to 1 / 3 of the depth of the collection pit.

[0011] The beneficial effects of adopting the above-mentioned improved scheme are as follows: By specifying the height relationship between the hinge shaft position of the guide plate and the bottom surface of the collection pit, as well as the vertical distance when the free end is hanging down, it is ensured that the tilt angle naturally formed by the guide plate under the action of gravity can not only allow the residual glue to slide down smoothly, but also provide sufficient space for the movement of the scraping plate when the scraping component is working. This distance setting also ensures that the free end of the guide plate will not be immersed in the residual glue at the bottom of the collection pit and cause blockage. At the same time, the hinge connection method allows the guide plate angle to be adjusted according to the glue with different viscosities, which enhances the applicability and flexibility of the device.

[0012] Furthermore, in the trapezoidal structure of the scraping plate, the length ratio of the upper base to the lower base is 1:1.5 to 1:2.5, and the included angle between the two waist sides of the scraping plate and the lower base is 60 to 75°.

[0013] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: By setting the ratio of the length of the upper and lower bottom edges of the trapezoidal structure of the scraping plate and the range of the angle between the waist edge and the lower bottom edge, the scraping plate can scrape a large area of ​​the bottom surface of the recovery chamber with a wider lower bottom edge when moving horizontally, while the narrower upper bottom edge reduces the resistance in the area where the upper part of the scraping plate connects with the drive rod. The trapezoidal waist edge angle design allows the residual glue to flow to both sides during the scraping process and finally converge into the collection pit, avoiding the accumulation of glue in front of the scraping plate. This geometric configuration improves the scraping efficiency and reduces the pushing force required by the drive rod.

[0014] Furthermore, the bottom edge of the scraper is provided with a downwardly extending serrated structure, each tooth tip of the serrated structure is triangular and the tooth spacing is 2~4mm, and the tooth height is 1~3mm.

[0015] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: by setting a serrated structure on the bottom edge of the scraper, the scraper can more effectively remove the cured or semi-cured colloids adhering to the bottom surface when it contacts the bottom surface of the recovery chamber by utilizing the cutting action of the tooth tips. The triangular tooth tip design of the serration increases the shearing force on the colloid. The setting of tooth spacing and tooth height ensures sufficient cutting ability while avoiding damage to the bottom surface of the chamber. At the same time, the serrated structure can also form tiny drainage grooves during the scraping process, so that the scraped residual colloid can move more smoothly to the rear without accumulating in front of the scraper.

[0016] Furthermore, the drive rod has a cylindrical structure, the gap between the outer diameter of the drive rod and the minor axis width of the sliding hole is 0.5~1.5mm, and the surface of the drive rod is provided with a longitudinal groove to prevent rotation.

[0017] The beneficial effects of adopting the above-mentioned improved scheme are as follows: by limiting the gap range between the cylindrical outer diameter of the drive rod and the short axis width of the sliding hole, it is ensured that the drive rod can slide smoothly in the sliding hole without jamming. At the same time, this gap setting can prevent residual glue from leaking from the sliding hole to the outside of the recycling cavity. The longitudinal groove on the surface of the drive rod achieves the anti-rotation function by cooperating with the inner wall of the sliding hole, ensuring that the scraping plate always maintains the correct working posture during the reciprocating movement, avoiding the decrease in scraping effect or interference between the scraping plate and the internal structure of the cavity caused by rotation.

[0018] Furthermore, the four inner walls of the recovery cavity are provided with rounded corner transition structures at the connection points with the bottom surface, and the radius of the rounded corner transition structures is 3~8mm.

[0019] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: by setting rounded transition structures at the connection between the four inner walls and the bottom of the recycling chamber, the problems of residual glue retention and cleaning dead corners that are easily caused by right-angle connections are eliminated. The rounded structure allows the residual glue to smoothly transition from the wall to the bottom during the flow process without accumulating at the corners. At the same time, the rounded design also makes it easier for the scraping plate to make closer contact with the edge area of ​​the bottom of the chamber during operation, avoiding the generation of scraping blind spots. The setting of this radius range ensures sufficient transition effect without affecting the effective volume of the recycling chamber due to excessive rounding.

[0020] Furthermore, the bottom surface of the collection pit is a conical recessed structure that slopes towards the center, and the cone angle of the conical recessed structure is 120~140°. A circular drain outlet is provided at the deepest part of the conical recessed structure.

[0021] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: by designing the bottom surface of the collection pit as a conical recessed structure inclined towards the center and opening a drain outlet at the deepest point, the function of automatic collection and discharge of residual glue in the collection pit is realized. The conical structure uses gravity to make the collected residual glue flow naturally towards the lowest point in the center. The setting of the cone angle range not only ensures sufficient inclination to achieve gravity drainage, but also avoids the problem of slow flow of residual glue caused by too small a cone angle. The circular drain outlet facilitates the connection of pipelines for centralized collection and subsequent treatment of residual glue. The overall design reduces the frequency of manual cleaning and improves the automation of residual glue recycling.

[0022] Furthermore, the guide plate is made of polytetrafluoroethylene or stainless steel, the thickness of the guide plate is 2-5mm, and the ratio of the width of the guide plate to the internal width of the recovery chamber is 0.8-0.95.

[0023] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: by selecting polytetrafluoroethylene or stainless steel as the material for the guide plate, the low surface tension and corrosion resistance of these materials are utilized, making it difficult for excess adhesive to adhere to the surface of the guide plate and allowing it to slide off smoothly. The thickness range ensures that the guide plate has sufficient rigidity to maintain a stable arc shape, while not increasing its own weight due to excessive thickness, which would cause excessive load on the hinge connection. The ratio of the guide plate width to the internal width of the cavity is set so that the guide plate can cover most of the lateral area to collect excess adhesive to the maximum extent, while leaving appropriate gaps on both sides to facilitate air circulation and pressure balance.

[0024] Furthermore, the connection between the scraper and the drive rod is fixed by welding. The scraper is made of carbon steel or stainless steel and has a thickness of 1.5~4mm. When the scraper moves horizontally back and forth under the drive rod, the vertical distance between its bottom edge and the bottom surface of the collection pit is maintained at 0.5~2mm.

[0025] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: by fixing the connection between the scraper and the drive rod by welding, the connection strength and stability between the two are guaranteed, avoiding the reduction of scraping effect due to loosening of the connection during reciprocating movement. The use of carbon steel or stainless steel as the scraper material provides sufficient strength and wear resistance to resist wear during long-term scraping operations. The thickness range setting ensures the rigidity of the scraper while avoiding driving difficulties caused by excessive weight. The vertical distance between the bottom edge of the scraper and the bottom surface of the collection pit allows the scraper to effectively remove residual colloids on the bottom surface without generating excessive resistance or scratching the bottom surface due to excessive contact.

[0026] Compared with existing technologies, the beneficial effects of the residual adhesive recovery device for honeycomb panel coating and pressing provided by this utility model are as follows: This utility model constructs a complete residual adhesive recovery system by setting up a recovery chamber with a sunken collection pit, an adjustable-angle arc-shaped guide plate, and a scraping component with a trapezoidal serrated scraper, realizing efficient processing of the entire process from residual adhesive reception, diversion, collection, cleaning to discharge. The rectangular trough structure of the recovery chamber, combined with the central collection pit, forms a reasonable spatial layout, allowing residual adhesive to quickly converge to the designated area; the guide plate, through hinged connection and arc design, can adapt to the needs of residual adhesive conveying at different flow rates, and its low-adhesion surface material can prevent adhesive residue; the scraping component, with its trapezoidal structure and serrated edges, achieves efficient cleaning of the bottom surface of the chamber, maintaining the long-term performance of the recovery chamber; the conical bottom design of the collection pit, combined with the central drain port, realizes automatic discharge of residual adhesive, reducing manual intervention. The entire device features a simple structure, few components, and clear connections, facilitating manufacturing and maintenance. The optimized design of the shape and dimensions of each component ensures reliable operation in actual production environments. Compared to existing technologies, this invention significantly improves residual adhesive recovery rates, reduces adhesive waste and environmental pollution, decreases equipment cleaning frequency and labor costs, and extends the service life of the recycling device. Furthermore, the use of a purely mechanical structure, eliminating the need for an electrical control system, results in higher reliability and a lower failure rate, making it particularly suitable for long-term stable operation on honeycomb panel production lines.

When the scraper moves horizontally back and forth under the drive rod, the vertical distance between its bottom edge and the bottom surface of the collection pit is maintained at 0.5~2mm.

[0043] The following is a specific embodiment 1 of this utility model: In this embodiment, the recovery chamber is welded from 304 stainless steel plate and is in the shape of a rectangular trough. Its external dimensions are 600mm long, 400mm wide, and 150mm high, with a wall thickness of 3mm. A sunken liquid collection pit is welded at the center of the bottom of the recovery chamber. The liquid collection pit is a circular concave structure with a diameter of 200mm and a depth of 60mm, which is about two-fifths of the total height of the recovery chamber. The bottom surface of the liquid collection pit is processed into a conical depression with a cone angle of 130°. The deepest part of the conical depression is located at the geometric center of the liquid collection pit. A circular drain pipe with an inner diameter of 25mm is welded at this point. The drain pipe extends downward through the bottom plate of the recovery chamber and is connected to an externally operable ball valve. The guide plate is made of 3mm thick polytetrafluoroethylene sheet, cut into a rectangular flat plate and then hot-bent into an arc shape. Its unfolded dimensions are 380mm long and 350mm wide, and the radius of curvature of the arc is 220mm, which is about 3 / 5 of the internal width of the recovery chamber (394mm). One long side of the guide plate is connected to the inner wall of one side of the recovery chamber through a stainless steel hinge shaft. The hinge shaft is located 110mm away from the bottom surface of the recovery chamber. The hinge is made of a stainless steel round rod with a diameter of 8mm and a shaft hole. The guide plate is connected to the hinge shaft through a stainless steel insert embedded in its edge, allowing the guide plate to rotate around the hinge shaft within a certain angle range. When the free end of the guide plate is in a natural hanging state, the vertical distance between its end and the bottom surface of the collection pit is 20mm, which is about one-third of the depth of the collection pit. The scraper plate in the scraping assembly is laser-cut from a 2.5mm thick carbon steel plate into a trapezoidal flat plate. Its upper base is 100mm long, and its lower base is 180mm long, with a length ratio of approximately 1:1.8. The height of the trapezoid is 150mm, and the angle between the two side edges and the lower base is 68 degrees. The lower edge of the scraper plate has a serrated structure, with each tooth being an isosceles triangle, 2mm high, and 3mm apart. A total of 60 teeth are machined on the lower edge. The drive rod is made of a 16mm diameter stainless steel round bar, 500mm long. One end of the drive rod is argon-arc welded to the geometric center of the scraper plate. Before welding, a hole is drilled in the corresponding position on the scraper plate, and the drive rod is inserted to form a plug-in fit before full welding. The surface of the drive rod is milled axially with a longitudinal groove 4mm wide and 2mm deep, extending from the middle of the drive rod to one end near the scraper plate. A long, narrow sliding hole is formed on one side wall of the recovery chamber. The long axis of the hole is horizontal, with a length of 300 mm and a short axis width of 18 mm. The drive rod passes through this sliding hole, and the gap between the outer diameter of the drive rod and the short axis width of the sliding hole is 1 mm. An inwardly protruding positioning rib is welded to the inner wall of the sliding hole corresponding to the groove of the drive rod. This positioning rib is embedded in the longitudinal groove of the drive rod to achieve an anti-rotation fit. The four inner side walls of the recovery chamber are all rounded with a radius of 5 mm at the connection points with the bottom surface using an angle grinder. The inner wall of the collection pit is also rounded with a radius of 4 mm at the connection point with the conical bottom surface.When the scraper blade moves horizontally reciprocating under the drive rod, the vertical distance between the tip of its bottom edge serrations and the bottom surface of the collection pit is maintained at approximately 1 mm. This distance is controlled by a limiting block installed on the outside of the sliding hole. The limiting block is welded to the outer wall of the recovery chamber, and the working height of the scraper blade can be finely adjusted by adjusting the position of the limiting block. The entire device weighs approximately 15 kg and has four support feet welded to the bottom for easy movement and positioning on the production site.

[0044] The following is another specific embodiment 2 of this utility model: This embodiment 2 is based on embodiment 1, and the structure of the guide plate is improved. Multiple raised guide ribs are welded or bonded at 50mm intervals along the width direction on the arc surface of the guide plate. Each guide rib is semi-cylindrical with a diameter of 6mm and a length consistent with the arc length of the guide plate. The guide ribs are made of the same polytetrafluoroethylene material as the guide plate and are fixed by bonding with a special adhesive. The function of these guide ribs is to form multiple parallel micro-channels on the surface of the guide plate, so that the residual glue is dispersed into multiple fine streams when flowing on the guide plate, avoiding the overflow or splashing phenomenon that may be caused by a large amount of residual glue flowing together. At the same time, the semi-cylindrical cross-sectional shape of the guide ribs can reduce the resistance to the flow of glue and maintain the continuity and stability of the flow. This improved structure is particularly suitable for processing glue with large flow rate or low viscosity that is easy to splash. The guiding effect of the guide ribs further improves the reliability of residual glue recovery and the cleanliness of the cavity. The structure and size of other components are consistent with those of embodiment 1.

[0045] The following is another specific embodiment 3 of this utility model: This embodiment 3 is based on embodiment 1, and improves the driving method of the scraping component. A handle structure is installed at one end of the drive rod extending to the outside of the recovery chamber. The handle is an L-shaped bend, and the long axis section of the bend is vertically fixed to the drive rod. The connection method is that a threaded joint is welded to the end of the drive rod, and the L-shaped bend is fixed by screwing in the thread. The L-shaped bend is made of stainless steel tubing with an outer diameter of 32mm and a wall thickness of 2mm. The long axis section is 150mm long, and the short axis section is 100mm long. A spherical grip with a diameter of 50mm is welded to the end of the short axis section. The spherical grip is covered with rubber material to increase grip comfort and anti-slip performance. The operator holds the handle. The structure allows for more effortless and precise control of the push-pull action of the drive rod. The L-shaped design of the handle makes the arm posture more ergonomic during operation, reducing fatigue during long-term operation. At the same time, a scale is added to the drive rod near the outer side of the sliding hole. The scale is marked on the surface of the drive rod by laser etching, with a scale interval of 10mm and a total length of 280mm, corresponding to the travel range of the scraping plate inside the cavity. By observing the scale, the operator can accurately control the movement distance of each scraping operation, ensuring the uniformity and thoroughness of the scraping operation. This improvement makes the scraping operation more convenient and efficient, especially suitable for high-intensity production environments that require frequent cleaning operations. The structure and dimensions of other components are consistent with those of Embodiment 1.

[0046] Specifically, the principle of this utility model is as follows: This device achieves efficient recycling of residual adhesive based on the principles of gravity guidance and mechanical scraping in fluid mechanics. When the residual adhesive extruded during the pressing and molding process of the honeycomb panel drips or flows into the recycling chamber, it first comes into contact with the surface of the arc-shaped inclined guide plate. Since the guide plate is made of low surface energy materials such as polytetrafluoroethylene or stainless steel, the residual adhesive slides down along the arc surface without large-area adhesion due to the combined action of gravity and surface tension on its smooth arc surface. The curvature radius and installation angle of the guide plate are optimized to keep the residual adhesive in a laminar flow state during the flow process, avoiding splashing and atomization caused by turbulence. After sliding down the guide plate, the residual adhesive enters the sunken collection pit at the bottom of the recycling chamber. The depth of the collection pit forms a relatively independent liquid storage space, separating the residual adhesive from other areas of the chamber. The conical concave structure at the bottom of the collection pit uses gravity to make the residual adhesive continuously converge towards the lowest point in the center, and achieves automatic discharge or periodic discharge through the drain port. During the residual adhesive recovery process, some adhesive will adhere to the inner wall of the recovery chamber and the surface of the guide plate. At this time, the scraping component comes into play. The operator pushes and pulls the drive rod to move the trapezoidal scraping plate horizontally back and forth on the bottom surface of the chamber. The trapezoidal shape of the scraping plate allows it to cover a large area with its wide bottom edge for scraping. The serrated structure of the bottom edge effectively removes the adhesive residue adhering to the bottom surface through the cutting and shearing action of the tooth tips. The scraped adhesive moves towards the collection pit under the push of the scraping plate and eventually falls into the pit. The small gap between the scraping plate and the bottom surface of the collection pit ensures the scraping effect while avoiding damage to the bottom surface. The rounded transition structure at the junction of the inner wall and the bottom surface of the chamber eliminates cleaning dead corners, allowing the scraping operation to cover the entire area. The entire device forms a complete residual adhesive treatment process through the organic coordination of four stages: diversion, concentration, scraping, and drainage. The shape and connection of each component are designed around the core goal of improving recycling efficiency and reducing cleaning difficulty. It does not require a complex power system and control device, and can achieve efficient residual adhesive recycling function by relying on simple mechanical structure and manual operation.

[0047] Before starting the honeycomb panel coating and pressing operation, place the residual adhesive recovery device directly below the pressing equipment or in the main area where residual adhesive drips. Ensure the opening of the recovery chamber is facing upwards and is horizontal. Adjust the tilt angle of the guide plate according to the viscosity and flow rate of the adhesive being used. For adhesives with higher viscosity, slightly tighten the hinge to increase the tilt angle of the guide plate and accelerate the flow rate. For adhesives with lower viscosity, allow the guide plate to hang naturally. During the pressing process, the extruded residual adhesive drips or flows naturally into the recovery chamber and is guided by the guide plate to collect in the collection pit. Operators should regularly observe the residual adhesive level in the collection pit. When the level reaches two-thirds of the depth of the collection pit, discharge it through the collection container connected below the drain port or directly open the drain valve for timed drainage. During continuous production, it is recommended to perform a scraping and cleaning operation every 2 to 4 hours. When operating, hold the drive rod and push it from the outside of the recovery chamber inwards. The scraping plate will then move across the bottom surface of the chamber. Use a uniform force and speed to perform a reciprocating scraping motion, ensuring each stroke covers the entire bottom surface of the chamber. Generally, 3 to 5 reciprocations are sufficient to clean the residual adhesive from the bottom surface. The scraped adhesive will automatically collect in the collection pit. After each day's production, a thorough cleaning should be performed. First, drain the remaining adhesive from the collection pit. Then, use the scraping assembly to completely scrape the bottom surface of the chamber. If necessary, use a cleaning solvent to wipe the surface of the guide plate to remove minor adhering substances. Regularly check the flexibility of the hinge shaft and the smoothness of the sliding holes. If adhesive seeps into the hinge or sliding holes, clean it promptly to maintain the long-term performance of the device. The entire operation is simple and easy to perform, requiring no professional skills training; ordinary production workers can master it proficiently.
