Description

Technical Field

[0001] This utility model relates to the field of edge banding machine technology, and more specifically, to a sheet metal air flotation platform. Background Technology

[0002] In the field of sheet metal processing, especially when edge banding long strips of sheet metal, severe surface wear is a common problem. Traditional worktables are in direct contact with the sheet metal, generating significant friction during sheet movement, leading to scratches or wear on the surface. For longer sheets, when edge banding one end, the other end is often suspended in the air. This unbalanced force causes excessive pressure on the contact area between the sheet metal and the worktable, resulting in line contact friction and further exacerbating surface wear.

[0003] Furthermore, existing equipment lacks effective support and cushioning structures, failing to reduce contact friction while ensuring stable movement of the sheet metal, severely impacting processing quality and product yield. Therefore, existing technologies urgently need improvement to address these issues. Utility Model Content

[0006] Furthermore, the platform body includes an air-floating base plate, the edge of which is formed with several vertical support plates, the top of which is provided with a platform, the platform having several air-floating holes, and the bottom of which is formed with at least one air duct.

[0007] Furthermore, the multiple vertical support plates are connected end to end to form a connecting ring, and the air-floating base plate, the connecting ring, and the platform form the internal cavity of the platform body.

[0008] Furthermore, several support columns are provided between the air-floating base plate and the platform.

[0009] Furthermore, a central hole is formed in the middle of the tabletop for the glue pot and the edge sealing assembly to pass through, and a rectangular slot is formed on the air-floating bottom plate to match the central hole.

[0013] The technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. The components of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application. It should be noted that similar reference numerals and letters in the following drawings indicate similar items; therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0014] In existing technologies, when edge banding machines process long strips of sheet material, the sheet material directly contacts the worktable during movement, leading to surface wear. When edge banding is performed on one end of the sheet material, the other end is suspended, forming a line contact area. Under gravity, this contact point generates concentrated stress, exacerbating the wear. Traditional support structures struggle to balance dynamic movement with local load-bearing requirements, resulting in damage to the sheet material's quality.

[0015] To address the aforementioned issues, and considering the phenomena of contact friction and stress concentration, it was found that non-contact support can reduce surface wear. Through fluid dynamics analysis, it was recognized that the duct structure can regulate flow velocity and pressure distribution. Therefore, it was proposed to optimize the airflow field through the ductwork, combined with top vents to form a continuous air film coverage.

[0016] like Figures 1-4 As shown, a sheet metal air flotation platform includes a platform body, which is hollow. An air flotation hole 101 is formed on the top of the platform body, and at least one air duct 2 is formed on the bottom of the platform body. The air duct is connected to the inner cavity of the platform body.

[0017] The platform body refers to the load-bearing structure with a sealed cavity, which can be achieved by welding steel plates to form a box-type frame, providing a channel for airflow circulation within the cavity. The air flotation holes are an array of through holes penetrating the top surface of the platform, which can be achieved by distributing a group of circular holes with a diameter smaller than the width of the plate, used to release compressed air to form a supporting air film. The duct refers to a tubular structure with the same cross-sectional dimensions.

[0018] Specifically, the bottom of the platform body is the edge banding machine base frame 200. This base frame supports the platform body and internal components, and can be constructed using welded steel plates to form a rectangular frame structure. Its internal space accommodates an air source, which can be a blower or compressed air, etc. The air source is placed inside the base frame. Air ducts are connected to the air source via pipes. The airflow from the air source enters the platform cavity through the ducts, while the compressed air escapes evenly through air flotation holes, forming a continuous air film layer on the bottom surface of the plate. When the plate moves, this air film layer isolates physical contact and reduces the coefficient of friction.

[0019] Through the above technical solution, this application effectively reduces surface wear during the movement of the plate, and the air film support evenly disperses the gravity load of the plate, avoiding local stress concentration.

[0020] Furthermore, the platform body includes an air-floating base plate 103, with several vertical support plates 102 formed on the edge of the air-floating base plate, a platform 100 provided on the top of the multiple vertical support plates, several air-floating holes 101 formed on the platform, and at least one air duct 2 formed at the bottom of the air-floating base plate.

[0021] The air-floating base plate is the substrate that supports the airflow channels. It can be made from stamped metal sheets and is used to support the upper structure and form the airflow cavity. The vertical support plate is a vertical plate perpendicular to the edge of the air-floating base plate. It can be connected to the air-floating base plate by welding or bolting and is used to construct a closed frame and improve structural rigidity. The tabletop is the wear-resistant layer covering the top of the vertical support plate. It can be made of phenolic resin composite material with an array of air-floating holes on the surface to evenly release airflow. The tabletop is not limited to phenolic wood; it can also be made of POM, wood, etc.

[0022] Specifically, the air-floating base plate and the vertical support plate are welded together to form a rigid frame, and the platform covers the top of the frame and is fixed with bolts. Air ducts installed at the bottom of the air-floating base plate are connected to an external air source via flanges. Airflow enters the inner cavity formed by the air-floating base plate, the vertical support plate, and the platform through the ducts. The airflow in the inner cavity is evenly released through the air-floating holes on the platform, forming a continuous air-film support plate.

[0023] Compared with existing technologies, the existing edge banding machine table uses physical contact support, which causes surface wear due to direct friction when the board moves. This solution releases airflow through air flotation holes to form non-contact support, eliminating friction and wear. In addition, the wear-resistant properties of the table further reduce table wear caused by airflow scouring. Through the above technical solution, this application achieves non-contact support between the board and the countertop, avoiding surface wear during movement; the air flotation hole array distribution on the countertop ensures uniform airflow release, maintaining the board in a stable suspended state.

[0024] Furthermore, multiple vertical support plates are connected end-to-end to form a connecting ring, and the air-floating base plate, the connecting ring, and the platform form the internal cavity of the platform body. The vertical support plates are connected end-to-end to form a ring-shaped support frame, transforming the originally dispersed support points into a continuous closed load-bearing structure.

[0025] Furthermore, a number of support columns 105 are provided between the air-floating base plate and the platform to provide support. The support columns can be nylon columns.

[0026] The nylon columns are cylindrical support structures made of nylon material, specifically cut from nylon rods with a diameter ranging from 5 to 15 millimeters. Their height can be adjusted according to the distance between the air-floating base plate and the platform. The distribution design of the nylon columns refers to their evenly spaced arrangement along the surface of the air-floating base plate, specifically using a rectangular array or a concentric circular array. The spacing between adjacent columns can be controlled within the range of 50-150 millimeters.

[0027] Specifically, the nylon columns are fixed between the air-floating base plate and the platform. Under the weight of the plate, they undergo elastic deformation, creating multiple local support points on the platform. When the plate moves, the nylon columns counteract vibration energy through their elastic restoring force, while their surfaces maintain sliding contact with the platform.

[0028] Compared to existing technologies, traditional edge banding machines lack an elastic support structure on their worktables. This solution utilizes multi-point contact with nylon columns, distributing the load on the sheet metal across multiple support areas and reducing the contact pressure to 1 / 5 to 1 / 10 of its original value. The elastic deformation of the nylon columns can reach 0.1-0.3 mm, effectively absorbing the instantaneous impact generated during sheet metal movement.

[0029] Through the above technical solutions, the maximum stress value in the contact area of ​​this application is reduced by 60%-80%, and the incidence of scratches on the board surface is reduced to less than one-third of the original level. The sliding friction coefficient between the nylon column and the tabletop is stabilized in the range of 0.15-0.25, which is more than 50% lower than the friction coefficient of 0.4-0.6 for direct contact between metal and bakelite.

[0030] Furthermore, a central hole 3 is formed in the middle of the tabletop for the glue pot and the edge sealing assembly to pass through, and a rectangular slot 4 is formed on the air-floating bottom plate to match the central hole.

[0031] The central hole refers to the through-hole structure located at the geometric center of the work surface. It can be implemented using a polygonal or composite curve profile, and its dimensions are determined based on the installation space requirements of the glue pot and edge-sealing components. This structure allows the equipment components to penetrate vertically through the work surface while maintaining the integrity of the air flotation hole distribution area. The rectangular slot refers to the opening structure on the air flotation base plate that matches the central hole. The central hole in the center of the work surface allows the glue pot and edge-sealing components to pass directly through the work plane for operation, while the corresponding rectangular slot on the air flotation base plate forms an equipment installation channel.

[0032] Furthermore, the platform body extends to form an end plate support portion 1, which is trapezoidal in shape.

[0033] The end plate support refers to the structure extending outward from the platform body, which can be achieved through welding or integral molding, and is used to provide support for the suspended ends of the plates. The trapezoidal shape refers to the support having a quadrilateral cross-section with non-parallel sides, and can be achieved using an isosceles trapezoid or a right trapezoid structure.

[0034] Specifically, when the long strip of material moves to the edge-sealing position, the suspended end is lifted by the extended support. The trapezoidal structure ensures that the edge of the material makes surface contact with the support, avoiding scratches caused by localized line contact. During the material's movement, the trapezoidal support maintains a stable contact surface, preventing sudden pressure changes in the contact area due to gravity. In some specific embodiments, the length of the support can be set to half of the maximum suspended length of the material.

[0035] Compared to existing technologies, traditional edge banding machine platforms lack external support structures, and the suspended ends of the sheet metal rely solely on the platform edges for line contact. This solution transforms line contact into surface contact through a trapezoidal support section, eliminating wear problems caused by excessive local pressure.

[0036] Through the above technical solution, this application effectively reduces the wear on the contact area between the suspended end and the platform during edge banding of long strip panels, avoiding surface scratches caused by line contact. During panel movement, the contact area between the support and the panel remains uniformly distributed, preventing material damage caused by sudden changes in local pressure under gravity.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model.
