Description

Technical Field

[0001] This utility model relates to the field of decorative panel production and processing technology, specifically to a glue removal mechanism for whole-house customized decorative panels used in edge banding machines. Background Technology

[0002] In the processing of decorative panels, the cutting and shaping of the panels exposes the cross-section of the core. These edges are prone to moisture absorption, damage, or cracking during use, affecting aesthetics and lifespan. Therefore, edge sealing is necessary. Edge sealing strips or materials are used to cover and bond the edges, which not only seals pores to prevent moisture and peeling, but also improves the uniformity of appearance, enabling the decorative panel to meet both durability and decorative requirements.

[0003] Edge banding is a high-frequency, repetitive process that requires high precision and bonding quality. Manual operation is inefficient and inconsistent. Edge banding machines can automatically feed, heat and seal the edge banding strip, press it tightly, and cut to finish, ensuring that the edge banding strip fits tightly to the board edge, is accurately positioned, and operates at a stable speed. This significantly increases production capacity, reduces labor costs, and ensures consistency in the appearance and joint strength of the finished product. It is a key piece of equipment on modern decorative panel production lines.

[0004] Currently, during the edge banding process, especially under high pressure or high temperature conditions, adhesive may be squeezed out along the gaps, resulting in glue overflow. This glue may stick to the upper and lower surfaces of the board or the transmission components of the machine tool, causing contamination of the finished product, dirt on the appearance, and causing malfunctions in subsequent processes such as drilling and sorting. At the same time, glue adhesion increases friction or jamming, leading to unstable conveying speed and delayed feeding in the later stages, affecting the production line cycle and yield.

[0005] Therefore, how to overcome the shortcomings of the existing technology mentioned above has become the subject of this utility model. Utility Model Content

[0006] The purpose of this invention is to provide a glue removal mechanism for whole-house custom decorative panels used in edge banding machines.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A glue removal mechanism for edge banding machines using custom-made decorative panels is disclosed. The edge banding machine includes a frame with a conveyor line for horizontally transporting the decorative panels. The glue removal mechanism includes at least one pair of glue removal heads and reciprocating drives corresponding to each glue removal head. All reciprocating drives are arranged along the conveyor line's transport direction on the side of the conveyor line. Each glue removal head includes a fixed base positioned and connected to the movable end of the reciprocating drive and a floating cutter head floatingly connected to the fixed base. The floating cutters of each pair of glue removal heads are opposite each other and spaced apart. The spacing between the floating blades of the head is less than or equal to the thickness of the decorative panel. When the conveyor line horizontally transfers the decorative panel, each pair of de-adhesive heads is configured to be located at the edges of two opposite surfaces of the decorative panel. When the conveyor line does not horizontally transfer the decorative panel, the floating blades of each pair of de-adhesive heads approach each other under the action of a reciprocating driver. When the conveyor line horizontally transfers the decorative panel, the decorative panel overcomes the resistance and pushes away the floating blades of each pair of de-adhesive heads to increase the spacing between the floating blades of each pair of de-adhesive heads and make the floating blades of the de-adhesive heads fit against the surface of the decorative panel.

[0008] In the above solution, the adhesive removal operation during the transfer of the decorative panel can be achieved through the cooperation of at least one pair of adhesive removal heads and a conveyor line. Specifically, the decorative panel is directly transferred horizontally through the conveyor line. When the conveyor line transfers the decorative panel to the area where the floating blade of the adhesive removal head is located, the decorative panel overcomes the resistance and pushes away the floating blade of each pair of adhesive removal heads, so as to increase the distance between the floating blades of each pair of adhesive removal heads and make the floating blade of the adhesive removal head fit against the surface of the decorative panel.

[0009] In existing technologies, when glue overflow occurs, a manual glue removal station is often set up. However, this operation is manual, which is labor-intensive and the quality is uncontrollable. This application differs from existing technologies by setting up a glue removal mechanism on the edge banding machine. That is, after the edge banding is completed, the glue removal operation is quickly carried out, which is highly efficient. At the same time, the floating blade of the glue removal head can float freely, so as to adapt to different decorative panel surfaces.

[0010] In a further technical solution, the floating blade head includes a guide plate and a scraper, which are arranged sequentially along the transfer direction of the decorative panel.

[0011] With the aforementioned technical design, when the decorative panel comes into contact with the floating blades of the pair of adhesive removal heads, it first contacts the guide plates that are close to each other, and then contacts the scraper. This ensures that the floating blades are gradually pushed open and adhere to the surface of the decorative panel during operation, achieving continuous removal of excess adhesive. The guide plates provide initial guidance and pre-extrusion, while the scraper performs the main adhesive removal action. Together, they improve the accuracy and stability of adhesive removal.

[0012] In a further technical solution, the guide plate is formed by bending a plate at a set angle, wherein when the conveyor line horizontally transfers the decorative panel, the outer surface of the bent corner of the guide plate is configured to abut against the surface of the decorative panel. When each pair of floating cutter heads is positioned opposite each other, the guide plates on each pair of floating cutter heads combine to form a horn-shaped guide, which has a large opening for introducing the trim panel and a small opening for exporting the trim panel.

[0013] With the above design, the decorative panel can smoothly enter through the large opening of the flared guide when it enters between each pair of adhesive removal heads. At the same time, the spacing between the large openings will be adaptively adjusted according to the thickness of the decorative panel, ensuring that the spacing at the small openings will also match the thickness of the decorative panel. This is because the guide plate and the scraper are positioned together on the fixed base. When the guide plate moves, the scraper will move with it, and the amount of movement is the same as that of the guide plate. This ensures that the excess adhesive can be effectively removed while avoiding damage to the edges and corners of the decorative panel.

[0014] In a further technical solution, multiple scrapers are provided, and the multiple scrapers are arranged in a linear array along the transfer direction of the decorative panel; when the bend of the guide plate is in contact with the surface of the decorative panel, the cutting edge of the scraper extends beyond the outer surface of the bend of the guide plate.

[0015] With the above design, multiple scrapers arranged in a linear array along the transfer direction of the decorative panel can effectively remove excess adhesive from the surface of the decorative panel.

[0016] In a further technical solution, the reciprocating drive is a telescopic cylinder, and the movable end of the telescopic cylinder is positioned and connected to the fixed base.

[0017] A further technical solution is that the conveyor line includes two conveyor tracks, which are parallel and spaced apart, and the distance between the two conveyor tracks is used for horizontal transfer of the decorative panel; the distance between the two conveyor tracks is greater than or equal to the thickness of the decorative panel; all reciprocating drives are paired in pairs, and each pair of reciprocating drives is fixedly connected to the two conveyor tracks respectively, and is located on the same side.

[0018] With the above design, the decorative panel is positioned between two conveyor tracks. This way, when the scraper removes excess glue, the decorative panel will not be unevenly stressed and thus will not tilt or deflect due to the constraint of the two conveyor tracks.

[0019] That is, the two conveyor tracks can clamp the decorative panels and move them horizontally.

[0020] A further technical solution involves sequentially setting up a glue removal station and a cleaning station along the conveyor line's transport direction, with the glue removal mechanism located at the glue removal station.

[0021] Thanks to the above-mentioned technical design, the edge banding machine can not only perform edge banding operations, but also remove glue and clean. For cleaning, existing equipment such as vacuum cleaners can be selected, which will not be elaborated on here.

[0027] The working principle and advantages of this utility model are as follows: In this invention, the adhesive removal operation during the transfer of decorative panels can be achieved through the cooperation of at least one pair of adhesive removal heads and a conveyor line. Specifically, the decorative panels are directly transferred horizontally through the conveyor line. When the conveyor line transfers the decorative panels to the area where the floating blades of the adhesive removal heads are located, the decorative panels overcome the resistance and push away the floating blades of each pair of adhesive removal heads, thereby increasing the distance between the floating blades of each pair of adhesive removal heads and making the floating blades of the adhesive removal heads fit against the surface of the decorative panels.

[0028] In the prior art, when glue overflow occurs, an additional device is often set up for glue removal. However, this operation is costly because it involves adding extra equipment. This application differs from the prior art by setting up a glue removal mechanism on the edge banding machine. That is, after the edge banding is completed, the glue removal operation is quickly performed, which is highly efficient. At the same time, the floating blade of the glue removal head has a floating state, so it can adaptively fit different decorative panel surfaces. Attached Figure Description

[0031] The present invention will be further described below with reference to the accompanying drawings and embodiments: Example: The present invention will be clearly described below with illustrations and detailed description. Any person skilled in the art who understands the examples of the present invention can make changes and modifications based on the technology taught in the present invention without departing from the spirit and scope of the present invention.

[0032] The terminology used herein is for the purpose of describing specific embodiments only and is not intended to limit the scope of this work. Singular forms such as “a,” “this,” “this,” “the,” and “the” as used herein also include plural forms.

[0033] See appendix Figure 1 - Figure 4 As shown, an adhesive removal mechanism for a whole-house customized decorative panel is disclosed in an edge banding machine. The edge banding machine includes a frame 1, on which a conveyor line 2 for horizontally transferring the decorative panel is provided. The adhesive removal mechanism includes at least one pair of adhesive removal heads 3 and reciprocating drives 7 corresponding to the adhesive removal heads 3. All reciprocating drives 7 are arranged along the conveyor line 2 on the side of the conveyor line 2 along the conveying direction. Each adhesive removal head 3 includes a fixed base 4 positioned and connected to the movable end of the reciprocating drive 7 and a floating cutter head 11 floatingly connected to the fixed base 4. The floating cutters 11 of each pair of adhesive removal heads 3 are opposite to each other and spaced apart. The spacing between the floating blades 11 of the glue removal head 3 is less than or equal to the thickness of the decorative panel. When the conveyor line 2 horizontally transfers the decorative panel, each pair of glue removal heads 3 is configured to be located at the edges of two opposite surfaces of the decorative panel. When the conveyor line 2 does not horizontally transfer the decorative panel, the floating blades 11 of each pair of glue removal heads 3 approach each other under the action of the reciprocating driver 7. When the conveyor line 2 horizontally transfers the decorative panel, the decorative panel overcomes the resistance and pushes away the floating blades 11 of each pair of glue removal heads 3 to increase the spacing between the floating blades 11 of each pair of glue removal heads 3 and make the floating blades 11 of the glue removal heads 3 fit against the surface of the decorative panel.

[0034] In this invention, the conveying direction of the conveyor line 2 can be a horizontal reciprocating motion or a vertical reciprocating motion. Here, a horizontal reciprocating motion is preferred because the decorative panel will not slide automatically due to gravity during horizontal transfer.

[0035] In this invention, the floating cutter head 11 is tilted before contacting the decorative panel, which allows the floating cutter head 11 to have a pre-pressure towards the panel, thereby enabling it to adaptively conform to the surface of the decorative panel.

[0036] The floating blades 11 of each pair of degumming heads 3 approach each other under the action of the reciprocating driver 7. This means that when the inclined floating blades 11 are installed, the reciprocating driver 7 brings the floating blades 11 closer to the decorative panel.

[0037] In this invention, the floating connection can be achieved directly through a spring, or through a rotating shaft with a torsion spring sleeved on the outside, preferably through a rotating shaft with a torsion spring sleeved on the outside. That is, the rotating shaft with the torsion spring sleeved on the outside positions and connects the floating cutter head 11 to the fixed base 4. Under normal circumstances, the torsion spring tilts the floating cutter head 11 at a certain angle. Once pushed by the decorative panel, it will push the floating cutter head 11 to deflect.

[0038] In this invention, the adhesive removal operation during the transfer of decorative panels can be achieved through the cooperation of at least one pair of adhesive removal heads 3 and the conveyor line 2. Specifically, the decorative panels are directly transferred horizontally through the conveyor line 2. When the conveyor line 2 transfers the decorative panels to the area where the floating blades 11 of the adhesive removal heads 3 are located, the decorative panels overcome the resistance and push away the floating blades 11 of each pair of adhesive removal heads 3, so as to expand the distance between the floating blades 11 of each pair of adhesive removal heads 3 and make the floating blades 11 of the adhesive removal heads 3 fit against the surface of the decorative panels.

[0039] In this invention, the set spacing generally needs to be less than or equal to the thickness of the decorative panel, but the set spacing cannot be too small and needs to meet the requirement of just scraping off the adhesive.

[0040] In the prior art, when glue overflow occurs, an additional device is often set up for glue removal. However, this operation is costly because it involves adding extra equipment. In contrast, this application sets up a glue removal mechanism on the edge banding machine, which can quickly remove glue after the edge banding is completed. This is highly efficient. At the same time, the floating blade 11 of the glue removal head 3 can float freely, so it can adaptively fit different decorative panel surfaces.

[0041] Preferably, the floating blade 11 includes a guide plate 5 and a scraper 6, which are arranged sequentially along the transfer direction of the decorative panel.

[0042] With the above-mentioned technical design, when the decorative panel comes into contact with the floating blades 11 of the pair of adhesive removal heads 3, it first contacts the guide plates 5 that are close to each other, and then contacts the scraper 6. This ensures that the floating blades 11 are gradually pushed open and adhered to the surface of the decorative panel during operation, achieving continuous removal of excess adhesive. The guide plates 5 provide initial guidance and pre-extrusion, while the scraper 6 completes the main adhesive removal action. The two work together to improve the accuracy and stability of adhesive removal.

[0043] Preferably, the guide plate 5 is formed by bending a plate at a set angle. When the conveyor line 2 horizontally transfers the decorative panel, the outer surface of the bent corner of the guide plate 5 is configured to abut against the surface of the decorative panel. When each pair of floating cutter heads 11 is arranged opposite to each other, the guide plates 5 on each pair of floating cutter heads 11 are combined to form a trumpet-shaped guide, which has a large opening 9 for introducing the decorative panel and a small opening 10 for exporting the decorative panel.

[0044] Metal plates can be selected for the plate, and the angle should be set according to actual needs; no further requirements are specified here. The outer surface of the bend corner is described based on the standard of the plate after bending; the bend corner is the inner surface.

[0045] With the above design, when the decorative panel enters between each pair of adhesive removal heads 3, it can smoothly enter through the large opening 9 of the trumpet-shaped guide. At the same time, the spacing between the large openings 9 will be adaptively adjusted according to the thickness of the decorative panel, ensuring that the spacing at the small openings 10 will also match the thickness of the decorative panel. This is because the guide plate 5 and the scraper 6 are positioned together on the fixed base 4. When the guide plate 5 moves, the scraper 6 will move with it, and the amount of movement is the same as that of the guide plate 5. This ensures that the excess adhesive can be effectively scraped off while avoiding damage to the edges and corners of the decorative panel.

[0046] It is important to note that, such as Figure 4 As shown, the small opening 10 is formed by the outer surface of the bend corner of the two guide plates 5.

[0047] Preferably, multiple scrapers 6 are provided, and the multiple scrapers 6 are arranged in a linear array along the transfer direction of the decorative panel; when the bend of the guide plate 5 is in contact with the surface of the decorative panel, the blade tip of the scraper 6 extends beyond the outer surface of the bend of the guide plate 5.

[0048] With the above design, multiple scrapers 6 arranged in a linear array along the transfer direction of the decorative panel can effectively remove excess adhesive from the surface of the decorative panel.

[0049] The scraper 6 and the guide plate 5 can be positioned and connected to the fixed base 4 using the same positioning connection method, for example, both can be fixed to the fixed base 4 by screws or pins.

[0050] It should be noted that the scraper 6 can be set at an angle or vertically, but it is preferred to set it at an angle here, so that the scraped impurities can be removed easily.

[0051] The reciprocating drive 7 can be a cylinder, a lead screw and sliding sleeve mechanism, or an electric push rod. Preferably, the reciprocating drive 7 is a telescopic cylinder, and the movable end of the telescopic cylinder is positioned and connected to the fixed base 4.

[0052] Preferably, the conveyor line 2 includes two conveyor tracks 8, which are parallel and spaced apart, and the distance between the two conveyor tracks 8 is used for horizontal transfer of the decorative panel; the distance between the two conveyor tracks 8 is greater than or equal to the thickness of the decorative panel; all reciprocating drives 7 are paired in pairs, and each pair of reciprocating drives 7 is fixedly connected to the two conveyor tracks 8 respectively, and is located on the same side.

[0053] With the above design, the decorative panel is positioned between two conveying tracks 8. When the scraper removes excess glue, the decorative panel will not be subject to uneven force and thus will not tilt or deflect due to the restriction of the two conveying tracks 8.

[0054] That is, the two conveyor tracks 8 can clamp the decorative panel and move the decorative panel horizontally.

[0055] Preferably, along the transport direction of conveyor line 2, a glue removal station and a cleaning station are sequentially arranged on conveyor line 2, and the glue removal mechanism is arranged at the glue removal station. Thanks to the above-mentioned technical design, the edge banding machine can not only perform edge banding operations, but also remove glue and clean. For cleaning, existing equipment such as vacuum cleaners can be selected, which will not be elaborated on here.

[0056] Working principle: like Figure 1 - Figure 4 First, based on the thickness of the decorative panel, drive the driving ends of the two telescopic cylinders to move closer to each other to reduce the distance between the floating blades 11 of the two degumming heads 3. In this case, the two guide plates 5 move closer to each other to form a trumpet-shaped guide, while the scrapers 6 arranged in a straight line will move away from each other (because the floating blades 11 are tilted at this time).

[0057] Once the trim panel enters the large opening 9, the spacing between the large openings 9 of the trumpet-shaped guide will be adaptively adjusted according to the thickness of the trim panel, ensuring that the spacing at the small opening 10 is also adapted to the thickness of the trim panel, so that the scrapers 6 arranged in a straight line fit against the surface of the trim panel. As the trim panel continues to be transported, the scrapers 6 can fully scrape off the excess adhesive from the surface of the trim panel.

[0058] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
