Description

Technical Field

[0001] This utility model relates to the field of edge banding technology for sheet metal, and in particular to a sheet metal pressing device and a sheet metal edge banding machine. Background Technology

[0002] With the rapid development of the panel furniture manufacturing industry, automated processing technology, especially edge banding technology, has become key to improving product quality and production efficiency. Edge banding, by bonding edge banding tape to the edges of the panels, not only beautifies the appearance of the furniture but also effectively prevents moisture from penetrating the panel, extending its service life. To replace traditional, inefficient manual operations, various automatic edge banding machines have emerged and become standard equipment on modern production lines.

[0003] In traditional technologies, automated edge banding machines typically employ an assembly line layout. For example, CN118061317A provides a non-standard CNC edge banding machine where the sheet material, after passing through the glue application station, is sent to the pressing station. This station primarily uses one or more sets of pressure rollers to apply pressure to the edge banding strip in a single horizontal direction, ensuring a tight fit between the strip and the vertical sides of the sheet material. The entire process is automated, offering significant speed and consistency advantages compared to manual operations when handling standard straight edge banding.

[0004] However, the limitations of traditional devices that apply pressure from only one direction become apparent when faced with increasingly complex board contour designs. For example, when the edge contour of the board is not a simple plane, but has grooves or steps on its upper or lower surface, simple horizontal pressure cannot effectively press the edge banding into these vertical grooves or contours. This results in the edge banding not fully adhering to the board at the grooves, easily creating gaps and weak adhesion. This not only affects the aesthetics of the product but also becomes a structural weak point, failing to meet the craftsmanship requirements of high-quality furniture. Utility Model Content

[0005] Therefore, it is necessary to provide a board pressing device and a board edge banding machine to address the above problems.

[0008] The pressing assembly, disposed on the base, includes a first pressing member for pressing the edge banding tape against the board in a first direction, and a second pressing member for pressing the edge banding tape against the board in a second direction. The first and second directions are arranged at an angle. The first and second pressing members are arranged along the feed direction of the conveyor line of the board edge banding machine, and either one of them can exert pressure on the upper surface of the board.

[0009] Optionally, the board has non-coplanar side end faces and top end faces. The first pressing member is used to abut the edge banding tape against the side end face of the board in the horizontal direction, and the second pressing member is used to abut the edge banding tape against the groove on the top end face of the board in the vertical direction. The first pressing member is arranged in front of the second pressing member along the feeding direction of the conveyor line.

[0010] Optionally, the first pressing member applies horizontal extrusion pressure to the side end face of the board, and the second pressing member applies vertical pressure in the vertical direction, with the two members set at 90° to each other.

[0011] Optionally, the first pressing component includes an arc-shaped template, the abutting surface of which is adapted to the side end face of the board. The arc-shaped template is used to press the lower end of the edge banding tape attached to the board to fit against the side end face of the board, and to guide the upper end of the edge banding tape to the groove located on the upper end face of the board.

[0012] The second pressing component includes a roller template, the end face of which is adapted to the groove on the upper surface of the board, for rolling the upper end of the edge banding into the groove on the upper surface of the board.

[0013] Optionally, the second pressing component further includes a flat template, which is positioned after the roller template along the feeding direction of the conveyor line. The lower end of the flat template abuts against the slot on the upper surface of the board, and is used to further press the upper end of the edge banding tape against the slot on the upper surface of the board.

[0014] Optionally, it also includes a horizontal drive assembly, which includes a guide rail, a slider, and a horizontal drive element disposed on the base;

[0015] The pressing assembly further includes a mounting plate connected to the slider. The bottom surface of the mounting plate is connected to the top surface of the slider. The mounting plate is used to mount a first pressing component or a second pressing component. Under the drive of the horizontal driving component, the mounting plate drives the first pressing component or the second pressing component to slide along the guide rail.

[0016] Optionally, the mounting plate is provided with guide holes, and the first pressing member and the second pressing member are provided with guide posts adapted to the guide holes. The guide posts pass through the guide holes and are slidably connected to the guide holes to adjust the height of the first pressing member or the second pressing member to adapt to plates of different thicknesses.

[0017] Optionally, the arc-shaped mold has a contact part and an extension part. The arc surface of the contact part is adapted to the side end face of the board. The extension part extends to the top of the slot on the upper end face of the board. Its vertical projection overlaps with the vertical projection of the second pressing part and falls into the slot. It is used to guide the upper end of the edge banding to the top of the slot so that the roller mold can roll the upper end of the edge banding into the slot on the upper end face of the board.

[0018] Optionally, the arc-shaped template includes a wedge-shaped arc-shaped template and a rectangular arc-shaped template. The contact surface of the wedge-shaped arc-shaped template gradually approaches the side end face of the board along the feed direction of the conveyor line to guide the edge banding tape to adhere to the board. The contact surface of the rectangular arc-shaped template is parallel to the side end face of the board. The wedge-shaped arc-shaped template and the rectangular arc-shaped template are arranged collinearly along the feed direction of the conveyor line.

[0019] Optionally, the width of the planar template is adapted to the width of the plate.

[0022] Optionally, an elastic element is provided between the first pressing member and / or the second pressing member and the mounting plate, the elastic element being used to drive the first pressing member and / or the second pressing member to move toward the mounting plate.

[0023] This application also provides a sheet metal pressing device, the sheet metal pressing device comprising:

[0024] Base;

[0025] The pressing assembly, disposed on the base, includes a first pressing member for pressing the edge banding tape against the board along a first direction, and a second pressing member for pressing the edge banding tape against the board along a second direction. The first direction and the second direction are arranged at an angle. The first pressing member and the second pressing member are arranged along the board feeding direction, and either one of them can exert pressure on the upper surface of the board.

[0026] This application also provides a board edge banding machine, including the above-mentioned board pressing device, and further including a pre-milling device, a feeding and gluing device and a conveyor line, wherein the pre-milling device, the feeding and gluing device and the board pressing device are arranged sequentially along the feeding direction of the conveyor line.

[0027] Compared with the prior art, the technical solution provided in this application has the following advantages:

[0028] The aforementioned board pressing device designs the pressing components as a first pressing member and a second pressing member arranged sequentially along the board feeding direction. The first and second pressing members press the edge banding tape along a first direction and a second direction, respectively, which are set at an angle. This allows the device to apply force to the edge banding tape from different angles. This multi-angle, step-by-step pressing method better adapts to the edge banding needs of boards with complex cross-sections (e.g., both sides and top surfaces need to be bonded, or even the top surface has a groove). Compared to traditional unidirectional pressing, this solution ensures that multiple contact surfaces of the edge banding tape and the board (such as the sides and top surface) receive sufficient and correctly oriented pressure, significantly improving the tightness and firmness of the bond. This avoids problems such as localized lifting or incomplete bonding caused by a single force direction, ultimately improving the edge banding quality and the product's aesthetics.

[0039] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0040] like Figure 1 As shown, the board of this utility model has non-coplanar side and top surfaces, wherein the top surface is flat and generally has a leather layer pressed onto it. The side surfaces are milled into arc-shaped, U-shaped, or other irregular shapes, requiring edge sealing. However, after pressing the edge sealing tape, the inventor found that the joint was uneven. The reason for this was that the angle between the side surface to be sealed and the top surface was almost 180°, and the existing leather layer and the added edge sealing tape were not of the same thickness, resulting in a height difference after splicing, thus causing unevenness. Therefore, a groove or step is formed at the joint.

[0041] See Figure 2 and Figure 3 An embodiment of this utility model provides a board pressing device, which is installed on the conveyor line of a board edge banding machine. The board pressing device includes: a base 100; and a pressing component 200, which is installed on the base 100 and includes a first pressing component for pressing the edge banding tape against the board along a first direction and a second pressing component for pressing the edge banding tape against the board along a second direction. The first direction and the second direction are arranged at an angle. The first pressing component and the second pressing component are arranged along the feed direction of the conveyor line, and either one of them can exert pressure on the upper surface of the board.

[0042] An embodiment of this utility model also provides a board pressing device, which includes: a base 100; and a pressing component 200 disposed on the base 100, including a first pressing member for pressing the edge banding tape against the board along a first direction, and a second pressing member for pressing the edge banding tape against the board along a second direction. The first direction and the second direction are arranged at an angle, and the first pressing member and the second pressing member are arranged along the board feeding direction, and either one of them can exert pressure on the upper surface of the board.

[0043] By designing the pressing assembly 200 as a first pressing member and a second pressing member arranged sequentially along the board feeding direction, the first pressing member and the second pressing member press the edge banding tape along a first direction and a second direction arranged at an angle, respectively. This allows the device to apply force to the edge banding tape from different angles. This multi-angle, step-by-step pressing method can better adapt to the edge banding needs of boards with complex cross-sections (such as needing to be pressed on both the sides and the top surface, or even having a groove on the top surface). Compared to traditional unidirectional pressing, this solution ensures that multiple contact surfaces of the edge banding tape and the board (such as the sides and the top surface) receive sufficient and correctly oriented pressure, thereby significantly improving the tightness and firmness of the bonding, avoiding problems such as localized lifting or incomplete bonding caused by a single direction of force, and ultimately improving the edge banding quality and the aesthetics of the product.

[0044] It should be noted that the two embodiments described above do not specifically limit the first direction and the second direction, or the angle between them. For example, the first direction can be horizontal or vertical, and the second direction can be perpendicular to the first direction at a 90° angle. The first or second direction can be from top to bottom or from bottom to top, meaning that both downward pressing and upward pushing methods can be used to press the board and edge banding. In this embodiment, it is preferred that the first direction is horizontal and the second direction is a top-down pressing method.

[0045] The pressing devices provided in the two embodiments above can be used as standalone equipment or integrated into the production line of the board edge banding machine.

[0046] See Figures 2 to 4 as well as Figure 8 In one embodiment, the board has a non-coplanar side end face and a top end face. A first pressing member is used to abut the edge banding tape against the side end face of the board in a horizontal direction, and a second pressing member is used to abut the edge banding tape against the groove on the top end face of the board in a vertical direction. The first pressing member is disposed in front of the second pressing member along the feeding direction of the conveyor line.

[0047] Based on this, in this embodiment, the first pressing component is positioned at the front of the feed direction and operates horizontally, firmly pressing the main body of the edge banding tape onto the side end face of the board, completing the basic positioning and bonding, and laying the groundwork for subsequent steps. Next, the second pressing component, located at the rear, applies force vertically, specifically responsible for pressing the upper part of the edge banding tape into the groove on the top surface of the board. This orderly process of first bonding the side and then pressing the top groove, along with the coordination of horizontal and vertical orthogonal directions, avoids problems such as uneven stress, localized voids, or inaccurate positioning that can easily occur when attempting to complete complex contour bonding with a single action. In this way, it is ensured that every part of the edge banding tape receives the correct directional and appropriate clamping force, thereby achieving a double, seamless, and secure bonding within the side and top grooves of the board, greatly improving the edge banding quality and appearance of the product.

[0048] See Figure 4 In one embodiment, the first pressing member includes an arc-shaped template 210, the abutting surface of which is adapted to the side end face of the board. The arc-shaped template 210 is used to press the lower end of the edge banding attached to the board to fit against the side end face of the board, and to guide the upper end of the edge banding above the slot on the upper end face of the board.

[0049] The second pressing component includes a roller template 220, the end face of which is adapted to the groove on the upper surface of the board, for rolling the upper end of the edge banding into the groove on the upper surface of the board.

[0050] In this embodiment, the first pressing component uses an arc-shaped template 210. Its arc-shaped contact surface can apply stable pressure to the side of the board while gently guiding and bending the upper part of the edge banding strip to the upper surface of the board using a smooth curved transition. This method avoids defects such as hard breakage of the edge banding strip, surface scratches, or white edges that may occur when using sharp-angled or right-angled templates, ensuring the integrity and aesthetics of the material.

[0051] Secondly, the second pressing component uses a roller template 220, replacing flat or scraping pressure with rolling pressure. This significantly reduces the relative sliding friction between the pressing component and the edge banding tape, effectively protecting the surface of the edge banding tape, especially suitable for high-gloss or finely textured finishes. Furthermore, the roller can apply continuous, concentrated line pressure. This pressure mode is highly effective for pressing the edge banding tape into the corners of the groove, squeezing out air bubbles, and ensuring even distribution of adhesive. The roller's edge end face is designed to fit the groove of the board, ensuring that pressure is precisely applied to every point requiring bonding, resulting in a seamless fit.

[0052] In summary, by combining the flexible guidance of the curved surface template 210 with the low-friction, high-precision rolling of the roller template 220, this solution not only achieves complex pressing functions, but also fully considers the protection of materials and the optimization of final molding quality during the execution process.

[0053] See Figure 4 In one embodiment, the second pressing component further includes a flat template 230, which is disposed after the roller template 220 along the feeding direction of the conveyor line. The lower end of the flat template 230 abuts against the slot on the upper end surface of the board and is used to further press the upper end of the edge banding tape to fit the slot on the upper end surface of the board.

[0054] In this embodiment, the lower end abutting surface of the planar template 230 is specifically an arc surface that is the same as the groove surface. By adding a planar template 230 after the roller template 220, a two-stage pressing mode of dynamic rolling forming + static smoothing and shaping is constructed, which improves the bonding strength of the sealing strip in the groove and the final flatness.

[0055] The main advantage of the roller template 220 is its low-friction, high-efficiency initial pressing of the edge banding into the groove contour, but its contact with the board is instantaneous line contact. The subsequent flat template 230 compensates for this. As the board continues to advance, the pre-formed edge banding slides over the flat template 230, which has the same fitting contour. This process has two effects: First, it provides continuous, planar pressure holding time. This continuous pressure is crucial for adhesives such as hot melt adhesives that require time to cool and cure to reach maximum bond strength, effectively preventing the edge banding from springing back or partially peeling before the adhesive is fully cured due to internal stress. Second, the flat template 230 acts as the final shaping and smoothing agent. It eliminates minor imperfections or unevenness that may occur during the rolling process, ensuring that the edge banding surface is perfectly flush with the upper surface of the board and tightly fitted to the inner contour of the groove.

[0056] Therefore, through the orderly cooperation of the rollers and the flat template 230, the device achieves a perfect combination of rapid shaping and long-term pressure holding and shaping of the edge banding, ensuring that the final edge banding effect is not only accurate in outline, but also exceptionally strong in adhesion and smooth in surface, significantly improving the durability and process quality of the product.

[0057] See Figure 5 In one embodiment, it also includes a horizontal drive assembly 300, which includes a guide rail 310, a slider 320 and a horizontal drive member 330 disposed on the base 100.

[0058] The pressing assembly 200 also includes a mounting plate 240 connected to the slider 320. The bottom surface of the mounting plate 240 is connected to the top surface of the slider 320. The mounting plate 240 is used to mount the first pressing component or the second pressing component. Under the drive of the horizontal drive component 330, the mounting plate 240 drives the first pressing component or the second pressing component to slide along the guide rail 310.

[0059] In sheet metal processing, the width of sheets often varies between different batches or products. By setting up a horizontal drive component 300, the pressing device can be driven by a horizontal drive component 330 (such as a servo motor or cylinder) to precisely and smoothly slide the entire pressing component 200 on the guide rail 310 according to the actual width of the sheet metal to be processed. This allows the pressing template to move quickly and accurately to a working position that adapts to the edge of the sheet metal, thus accommodating sheet metal processing tasks of different widths and avoiding the need for tedious and time-consuming manual mechanical adjustments due to changes in specifications. This automated adjustment capability not only significantly shortens the preparation time for changing production batches and improves overall production efficiency, but also ensures the repeatability of each positioning through precise program control, avoiding errors that may be caused by manual adjustments, thereby ensuring stable processing quality.

[0060] See Figure 5 and Figure 7 In one embodiment, the mounting plate 240 is provided with a guide hole, and the first pressing member and the second pressing member are provided with guide posts 250 adapted to the guide hole. The guide posts 250 pass through the guide hole and are slidably connected to the guide hole, and are used to adjust the height of the first pressing member or the second pressing member to adapt to the plates of different thicknesses.

[0061] This embodiment introduces crucial vertical adjustment capability into the pressing device, enabling it to fully adapt to different sheet material specifications. Combined with the aforementioned horizontal drive component 300 (for accommodating sheet width), the sliding fit structure of the guide post 250 and guide hole is specifically designed to accommodate variations in sheet thickness. In actual production, sheet thickness (e.g., 16mm, 18mm, 25mm, etc.) is another frequently changing key parameter. This design allows operators to easily slide and fix the first and second pressing components, ensuring that regardless of whether the sheet is thin or thick, the pressing template (e.g., curved template 210, roller template 220) can be precisely aligned with the vertical position of the side end face and upper surface groove of the sheet. This Z-axis adjustment capability gives the equipment comprehensive adaptability in three-dimensional space (width X, feed Y, thickness Z). This sliding adjustment structure is simple and reliable, ensuring both ease of adjustment and, through the tight fit of the guide post 250 and guide hole, ensuring the vertical stability and posture accuracy of the pressing components during operation. This is a key design feature for achieving multi-specification compatibility and enhancing market competitiveness.

[0062] See Figure 6 In one embodiment, the curved surface template 210 has a contact portion and an extension portion. The curved surface of the contact portion is adapted to the side end face of the board, and the extension portion extends to the top of the slot on the upper end face of the board. Its vertical projection overlaps with the vertical projection of the second pressing member and falls into the slot, which is used to guide the upper end of the edge banding to the top of the slot so that the roller template 220 can roll the upper end of the edge banding into the slot on the upper end face of the board.

[0063] The curved surface of the mating part adapts to the side end face of the board, undertaking the basic horizontal pressing function, firmly pressing the main body of the edge banding tape onto the side end face of the board. The extension part extends to directly above the groove on the upper end face of the board, and its vertical projection coincides with the vertical projection of the second pressing part. Specifically, when the board moves forward on the conveyor line, the upper end of the edge banding tape is first pre-pressed by the extension part of the curved surface template and held directly above the groove. Since the projections of the extension part and the roller template coincide, the edge banding tape leaves the constraint of the extension part and enters the working range of the roller template. This coincidence of the guiding tool and the executing tool in the action path ensures that the final position of the guide is the starting position of the rolling, which not only guarantees the accuracy of the rolling action, but also avoids various defects caused by misalignment.

[0064] The vertical projection of the extension into the slot does not simply bend the upper end of the edge banding, but acts like a guide groove, forcibly guiding and pre-positioning the upper part of the edge banding to the position where the subsequent roller template 220 will be applied. This ensures that the part of the edge banding to be pressed in is perfectly aligned with the entrance of the groove before entering the next rolling process.

[0065] See Figure 6 In one embodiment, the arc-shaped template 210 includes a wedge-shaped arc-shaped template 211 and a rectangular arc-shaped template 212. The contact surface of the wedge-shaped arc-shaped template 211 gradually approaches the side end face of the board along the feed direction of the conveyor line to guide the edge banding tape to adhere to the board. The contact surface of the rectangular arc-shaped template 212 is parallel to the side end face of the board. The wedge-shaped arc-shaped template 211 and the rectangular arc-shaped template 212 are arranged collinearly along the feed direction of the conveyor line.

[0066] The gradually inward-curving wedge-shaped surface of the wedge-shaped mold 211 allows the edge banding, freshly applied with adhesive, to be smoothly and without impact guided towards the side surface of the board. This process avoids problems such as edge banding misalignment, excessive instantaneous compression of the adhesive, or wrinkling of the edge banding itself that could occur due to sudden contact and pressure, ensuring a smooth transition in the pressing action, which is a necessary prerequisite for ensuring the subsequent bonding quality. Since the edge banding has now been precisely guided into place by the wedge-shaped mold, the rectangular section of the subsequent rectangular mold 212, parallel to the side of the board, can apply a stable and uniform pressure, fully and thoroughly pressing the edge banding against the side of the board without any dead angles, ensuring a tight and bubble-free adhesive layer.

[0067] In summary, this two-stage design, which involves guiding followed by compaction, breaks down the single action of side sealing into two clearly defined and seamlessly connected sub-processes. Through meticulous structural division, it systematically solves various process problems that may arise during high-speed bonding, ultimately achieving a more reliable and aesthetically pleasing side sealing effect.

[0068] In one embodiment, the width of the flat template 230 is adapted to the width of the sheet material. The flat template 230, following the roller template 220, is a component that provides final pressure and shaping to the edge banding tape already pressed into the groove. During operation, it applies a downward pressure to the upper surface of the sheet material. If the width of the template is much smaller than the width of the sheet material, this downward pressure will concentrate in a localized area of ​​the sheet material. For thinner or wider sheets, this can easily lead to elastic deformation, warping, or vibration during transport, thereby compromising the flatness and uniformity of the pressing. By adapting the width of the flat template 230 to the width of the sheet material, the downward pressing force can be evenly distributed across the entire width of the sheet material, firmly pressing the sheet material as a whole onto the conveyor line below. This not only completely avoids the risk of unstable deformation of the sheet material during processing but also ensures that the edge banding tape within the groove receives equal and continuous pressure along its entire length, thereby achieving the most reliable adhesive strength and optimal surface flatness.

[0069] See Figure 2 and Figure 4 In one embodiment, multiple planar templates 230 are provided, and the width of each planar template 230 is adapted to the width of the sheet material. Compared to manufacturing a single, large, and variable template, using multiple standardized template units spliced ​​or arrayed can more easily and economically cover various processing size requirements, from narrow to wide panels. When processing narrow panels, fewer templates can be used; when processing wide panels, more templates can be used, thus achieving flexible adjustment of the total width. This greatly enhances the versatility of the equipment and its ability to respond quickly to different orders.

[0070] Secondly, setting multiple planar templates 230 can effectively extend the overall pressure holding length, thereby increasing the pressure holding time during bonding. On high-speed conveyor production lines, a longer pressure holding time means the adhesive has more time to cool and cure, forming stronger adhesion. This is crucial for preventing the edge banding from springing back and enhancing its long-term durability. Simultaneously, the layout of multiple templates also makes segmented pressure control possible. For example, the front template can be designed with higher pressure for strong compression, while the rear template can have slightly lower pressure for smooth curing, enabling more precise process control during bonding and further optimizing the adhesion quality.

[0071] See Figure 2 and Figure 5In one embodiment, a lifting component 400 is provided on the bottom surface of the base 100, which is used to drive the base 100 to move in the vertical direction.

[0072] See Figure 7 In one embodiment, an elastic element 260 is provided between the first and / or second pressing member and the mounting plate 240. The elastic element 260 is used to drive the first and / or second pressing members to move toward the mounting plate 240. In actual processing, there may be slight, unavoidable tolerances in the thickness or surface flatness of the board material. In a rigidly connected pressing system, these slight undulations can cause a sudden increase or decrease in pressing force, resulting in localized over-pressing (damaging the board material and edge banding) or incomplete pressing (generating air bubbles or delamination). By adding an elastic element 260 (such as a spring) between the pressing member and the mounting plate 240, the pressing member gains the ability to float along the direction of its sliding guide post.

[0073] When encountering areas with slightly thicker sheet material, the elastic element 260 is compressed, absorbing excess travel and maintaining the pressure applied to the sheet material within a relatively constant range, thus preventing overpressure damage. Conversely, when encountering slightly thinner areas, the elastic force of the elastic element 260 pushes the pressing component downwards to compensate, ensuring it maintains effective contact and necessary pressure with the sheet material surface at all times. This flexible connection not only ensures uniform and stable pressure but also effectively absorbs vibrations generated during transport, further guaranteeing the smoothness of the pressing process. This reduces the precision requirements of the incoming materials and enhances the reliability and stability of the process.

[0074] One embodiment of this utility model also provides a sheet metal edge banding machine, including the aforementioned sheet metal pressing device, as well as a pre-milling device, a feeding and gluing device, and a conveyor line. The pre-milling device, the feeding and gluing device, and the sheet metal pressing device are arranged sequentially along the feed direction of the conveyor line. This embodiment, by setting up a sequentially arranged assembly line structure, tightly connects the three core processes of edge banding—substrate pretreatment, gluing and bonding, and pressure forming—creating a synergistic effect.

[0075] The pre-milling device, as the first step, processes the sheet metal into the required shape and eliminates any chipping, burrs, or unevenness that may occur during the cutting process. This provides a perfect and clean reference surface for subsequent gluing, which is a fundamental prerequisite for achieving seamless bonding. The feeding and gluing device evenly and quantitatively applies adhesive and edge banding tape to the treated base surface, ensuring ideal bonding conditions. Finally, the sheet pressing device, as the crucial finishing step, applies its step-by-step, multi-directional, and adaptive flexible pressing capabilities to the sheet metal, ensuring the strongest and tightest bonding effect between the edge banding tape and the sheet metal, especially in complex groove contours.

[0076] By integrating the pressing device into a complete production line, not only is the individual pressing process optimized, but the final product of the board is also ensured to have high consistency, excellent durability and exquisite appearance, thus achieving a dual improvement in production efficiency and product quality.
