Abstract
Description
Technical Field
[0001] This invention relates to the technical field of sheet metal processing, and in particular to an integrated device for sealing side holes with adaptive clamping. Background Technology
[0002] In the modern panel processing and furniture manufacturing industry, edge banding and side wall drilling are two core processes that determine the quality, assembly precision, and performance of the finished product. The core function of edge banding is to seal the exposed substrate cross-section on the side of the panel, prevent moisture intrusion, and improve the appearance integrity, structural stability, and service life of the panel. Side wall drilling is mainly used to meet the needs of subsequent panel splicing, connector installation, and functional component assembly.
[0003] The current processing mode commonly used in the industry is still mainly based on split operation, that is, the edge banding is first completed by independent edge banding equipment, and then the board is transferred to a special drilling equipment to complete the side wall drilling. This traditional mode has exposed many technical defects that are difficult to overcome in actual production.
[0004] For example, Chinese patent CN116551807A discloses a sheet metal edge banding and side hole machine, which includes a frame body. The top of the frame body is sequentially equipped with a sheet metal preheating mechanism, an adhesive application mechanism, a tape application mechanism, a front and rear trimming mechanism, an edge trimming mechanism, and a side hole mechanism. By adding the side hole mechanism to the rear section of the fully automatic edge banding machine, side holes can be made synchronously with the edge banding machine, forming a fully automatic integrated machine for edge banding and side hole making. The speed of edge banding is the same as the speed of hole making, and the edge banding is completed at the same time as the hole making. The whole equipment operates on an assembly line, reducing the number of operators for the side hole machine and reducing the process of transporting the sheet metal to the side hole equipment after edge banding. This greatly saves manpower and reduces the process defect rate and loss of the sheet metal.
[0005] However, the aforementioned sheet metal edge banding and side hole machine still has some shortcomings in actual use: 1. First, although the existing equipment integrates edge banding and drilling equipment, it generally does not achieve safe interlocking and timing coordination between edge banding and drilling actions, which poses a serious risk of action interference and accidental start. It often happens that the edge banding clamping mechanism is accidentally opened during the drilling process, or the drilling electric drill is accidentally started during the normal operation of the edge banding process. This not only makes it impossible to achieve stable processing, but also poses a high risk of equipment safety.
[0006] 2. In the aforementioned existing equipment, when the drilling drill performs drilling operations on the side wall of the board, the high-speed rotating drill bit will generate continuous and concentrated radial torque and high-frequency vibration. Since the edge sealing action and the drilling action are integrated into one, and the two are very close, the edge sealing layer has just been bonded, and the adhesive used for bonding has not yet completely solidified. Drilling directly on it will cause the newly bonded edge sealing strip to be separated and misaligned due to torque, resulting in the complete scrapping of the entire edge sealing layer.
[0007] 3. Secondly, traditional edge banding equipment generally uses the method of heating the side of the board. When dealing with larger and thicker boards, the heat conduction path is too long and the heating speed is slow. At the same time, the edge banding strip itself is not effectively heated and softened, and always maintains a highly rigid original state. When performing edge banding operations on the corners and turning parts of the board, the edge banding strip cannot flexibly adapt to the shape of the board, and is prone to problems such as bending and breaking, surface cracking, hard rebound, and local deformation.
[0008] Therefore, based on the above-stated viewpoints, there is still room for improvement in existing sheet metal edge banding and side hole machines for sheet metal processing. Summary of the Invention

The middle part of the linkage is rotatably located on the inner wall of the processing frame. The softening section includes two sets of heating rollers inside the processing frame to soften the edge banding strip.
[0010] Preferably, the protrusion has an opening, and a reciprocating groove is provided on one side of the protrusion for the pressing roller to move back and forth. The pressing roller is slidably disposed in the reciprocating groove of the protrusion. An adaptive compression spring is installed between the protrusion and the processing frame; The protrusion is also provided with a reciprocating component, which includes a reciprocating toothed frame connected to the pressing roller and slidably disposed on the side wall of the protrusion. An incomplete gear rotatably disposed on the side wall of the protrusion is meshed in the middle of the reciprocating toothed frame. A control motor is installed on one side of the protrusion, and the output end of the control motor extends toward and is connected to the incomplete gear.
[0011] Preferably, the processing frame is also provided with a limiter for positioning the board material. The limiter includes two limit arms that are symmetrically connected by a torsion spring in the height direction of the processing frame. A limit roller is rotatably installed at the end of the limit arm away from the processing frame. By adjusting the angle of the limit arm, the limit roller is made to abut against the board material, while ensuring the edge sealing and pressing accuracy.
[0012] Preferably, the limiting arm is a telescopic structure, which includes a fixed arm and a telescopic arm. The fixed arm and the telescopic arm have a telescopic hole, and a locking screw is provided in the telescopic hole.
[0013] Preferably, a bidirectional electrically controlled telescopic rod is also installed in one side of the processing frame, and an execution plate is installed on the output end of the bidirectional electrically controlled telescopic rod, with the two execution plates having a wave-like shape on opposite sides.
[0014] Preferably, a support frame is also installed on the side wall of the processing frame. The support frame is equipped with an adhesive nozzle for spraying adhesive onto the edge banding strip. The support frame is also equipped with an anti-diffusion plate to protect the edge banding strip and prevent the adhesive from spreading. The anti-diffusion plate also blocks the drilling station to prevent drilling debris from contaminating the adhesive.
[0015] Preferably, the drilling drill is equipped with a processing unit that works in conjunction with the edge sealing pressing action. The processing unit includes an execution slot opened on the C-shaped fixing frame, symmetrical fixing plates are slidably installed in the execution slot of the C-shaped fixing frame, and two clamping plates are symmetrically installed in the height direction of the C-shaped fixing frame.

[0020] Second, the softening section of this invention uses symmetrical heating rollers to directly heat and soften the edge banding strip, eliminating the need for overall heating of the heavy board. This results in high heating efficiency, uniform softening, and significantly improved flexibility of the edge banding strip. It can flexibly adapt to corners and transitions of the board, effectively preventing the edge banding strip from bending, breaking, cracking, or deforming.
[0021] Third, the present invention drives the pressing roller to move back and forth along the reciprocating groove through reciprocating parts (incomplete gear, reciprocating tooth frame), which can eliminate air bubbles between the edge banding strip and the board and achieve uniform pressing; at the same time, with the adaptive pressing structure, it can effectively resist the torque during drilling, avoid poor edge banding, lifting and loosening, and improve the edge banding firmness and flatness.
[0022] Fourth, this invention achieves linkage between the protruding block and the C-shaped fixing frame through a linkage rod, and in conjunction with clamping positioning and gear rack linkage, it not only achieves safety interlocking between drilling and edge sealing operations, but also achieves safety interlocking after edge sealing is pressed in place before drilling is started, avoiding action interference and misoperation; multiple positioning work together to resist drilling torque, ensuring edge sealing integrity and drilling accuracy.

[0035] The following combination Figures 1-10 This application will be described in further detail.
[0036] This application discloses an integrated device for edge sealing with adaptive clamping, which realizes the synchronous and continuous processing of edge sealing and side wall drilling of the board, while ensuring that the two processes do not interfere with each other. The edge sealing strip 100 is softened by a targeted heating structure, and the edge sealing bonding quality is improved by an adaptive clamping structure, ultimately achieving efficient and stable integrated processing of the board.
[0037] Reference Figure 1 and Figure 2 As shown, an integrated device for sealing side holes with adaptive clamping includes a stationary processing platform 1. The processing platform 1 is provided with a strip processing area for moving the sheet material. The strip processing area is arranged along the extension direction of the processing platform 1 to provide a stable path for continuous processing of the sheet material. The sheet material can move at a constant speed along the strip processing area. When the sheet material moves to the designated area, it stops moving and performs a drilling operation.
[0038] The strip processing area of processing platform 1 is also equipped with: a softening part 2 for softening the edge banding strip 100 of the board; and an integrated processing part 3 for simultaneously completing edge banding and side wall drilling of the board.
[0039] The softening section 2 and the integrated processing section 3 are connected sequentially along the moving direction of the board to ensure that the edge banding strip 100 is fully heated and softened before entering the bonding and drilling station, thus solving the problem that the edge banding strip 100 is not heated and the corner edge banding is prone to breakage and deformation in traditional equipment.
[0040] The softening section 2 adopts a targeted heating design, which acts directly on the edge banding strip 100 without the need for overall heating of the heavy board. This ensures that the edge banding strip 100 softens evenly, enhances its flexibility, and enables it to flexibly adapt to the edge banding requirements of the board corners and turning points, effectively avoiding problems such as bending, breakage, cracking, and deformation.
[0041] Reference Figure 3 and Figure 4 As shown, the integrated processing unit 3 includes two processing frames 30 that are hinged to each other. One end of the edge banding strip 100 is inserted into one processing frame 30, then passes through the other processing frame 30, and extends outward to the unwinding roller 31 on the processing platform 1. The processing frame 30 is also provided with a pressing roller 32 for pressing the edge banding strip 100 to make it adhere to the side wall of the board. The processing frame 30 is also provided with protrusions 33 for the pressing roller 32 to distribute.
[0042] Reference Figure 5 and Figure 6 As shown, the integrated processing unit 3 also includes a drilling drill 34 and a C-shaped fixing frame 35 integrated and installed on the processing frame 30. The drilling drill 34 and the pressing roller 32 are arranged in a front-to-back integrated work position, and the drilling drill 34 is located on the inner wall of the C-shaped fixing frame 35.
[0043] A linkage rod 36 is provided between the protrusion 33 and the C-shaped fixing frame 35. One end of the linkage rod 36 is hinged to the protrusion 33, and the other end is hinged to the C-shaped fixing frame 35. The middle part of the linkage rod 36 is rotatably mounted on the inner wall of the processing frame 30 through a torsion spring.
[0044] Note: The two hinged machining frames 30 can rotate relative to each other around the hinge point, and the main control motor 10 is mounted on one of the machining frames 30 (see reference). Figure 4 As shown), the main control motor 10 can control the rotation of the processing frame 30 on one side, which can not only adapt to the processing needs of the side of the board at different angles, but also further optimize the synergistic effect of edge sealing and drilling through angle adjustment.
[0045] The unwinding roller 31 can achieve stable unwinding and moderate tension control of the edge sealing strip 100, avoid its slack or excessive stretching, provide a stable foundation for edge sealing and bonding, and reduce the risk of displacement of the edge sealing strip 100 during punching.
[0046] Reference Figure 6As shown, an adaptive compression spring 37 is installed between the protrusion 33 and the processing frame 30, and a switching electric control rod 9 is installed on the outer wall of the processing frame 30. The output end of the switching electric control rod 9 is connected to the protrusion 33.
[0047] Switching the electric control lever 9 can control the extension distance of the processing frame 30, ensuring that the processing frame 30 can squeeze the edge banding strip 100 during edge banding. The purpose of setting the adaptive pressure spring 37 is to ensure that the pressure of the processing frame 30 on the edge banding strip 100 during edge banding is buffered, avoiding excessive pressure that would cause all the adhesive between the edge banding strip 100 and the board to be squeezed out, affecting its adhesion. Furthermore, it can also prevent uneven force on the edge banding strip 100.
[0048] Reference Figure 5 , Figure 6 and Figure 7 As shown, a bidirectional electrically controlled telescopic rod 50 is also installed inside the processing frame 30 on one side. An execution plate 51 is installed at the output end of the bidirectional electrically controlled telescopic rod 50. The two execution plates 51 are set in a wave-like shape on opposite sides. The wave-like structure can not only form a multi-point stable clamping of the edge banding strip 100 to achieve tension positioning, but also provide a unified reference positioning surface for drilling holes in the side wall, thereby improving the accuracy of the drilling position.
[0049] Meanwhile, the clamping action of the bidirectional electric telescopic rod 50 and the edge sealing action work together. One end of the edge sealing strip 100 is a movable end and the other end is a fixed end. The fixed end is wound on the unwinding roller 31. During the processing operation, the edge sealing strip 100 is first passed through the processing frame 30, and then the movable end of the edge sealing strip 100 is clamped between the clamping plates 72 to ensure that the edge sealing strip 100 is in a taut state under the cooperation of the clamping plates 72 and the unwinding roller 31, so as to ensure the convenience of heating, gluing and cleaning of the edge sealing strip 100.
[0050] Reference Figure 3 As shown, when the board needs to be edge-banded, the integrated processing unit 3 first performs edge-banding treatment on it. The processing frame 30 is equipped with a pressing roller 32 for applying rolling pressure to the edge banding strip 100 and making it stably adhere to the side wall of the board. At the same time, the processing frame 30 is equipped with protrusions 33 specifically for the installation and distribution of the pressing roller 32. The protrusions 33 provide stable support and movement guidance for the pressing roller 32.
[0051] The pressing roller 32 adopts a flexible and wear-resistant roller body structure, which can ensure sufficient pressing force and avoid scratching the surface of the edge sealing strip 100. At the same time, the rolling pressing method can disperse the pressure and reduce local stress concentration. Combined with the adaptive adjustment structure, it further improves the firmness of the edge sealing and resists the influence of the punching torque.
[0052] In actual operation, the protrusion 33 of the processing frame 30 is pressed against the side wall of the board, and then the pressing roller 32 begins to move back and forth repeatedly along the movement direction of the board, so that the edge banding strip 100 can be pressed against the side wall of the board. The reciprocating pressing of the pressing roller 32 can eliminate the air bubbles between the board and the edge banding strip 100, ensuring the flatness and integrity of the adhesion between the two.
[0053] Reference Figure 8 and Figure 9 As shown, the protrusion 33 is provided with a reciprocating groove 38 for the reciprocating movement of the pressing roller 32, and the protrusion 33 is also provided with a reciprocating component 39 for driving the pressing roller 32 to move.
[0054] The reciprocating component 39 includes a reciprocating toothed frame 360 connected to the pressing roller 32 and slidably disposed on the side wall of the protrusion block 33. An incomplete gear 361 is meshed in the middle of the reciprocating toothed frame 360. A control motor 362 is installed on one side of the protrusion block 33. The output end of the control motor 362 is connected to the incomplete gear 361. The control motor 362 drives the incomplete gear 361 to rotate continuously. Through meshing transmission, the reciprocating toothed frame 360 and the pressing roller 32 are driven to make directional reciprocating motion along the reciprocating slide groove 38, so as to realize the cyclic and uniform pressing of the edge sealing strip 100.
[0055] This cyclic pressing method can further enhance the adhesion between the edge banding strip 100 and the board, fill the gaps where the fit is not good, and at the same time disperse the local impact of the drilling torque on the edge banding area, thereby improving the torsional resistance of the edge banding structure.
[0056] During operation, after the control motor 362 starts, it drives the incomplete gear 361 to rotate continuously at a constant speed. When the toothed part of the incomplete gear 361 meshes with the upper side of the reciprocating gear frame 360, it drives the reciprocating gear frame 360 to move in a single direction, thereby driving the pressing roller 32 to move synchronously along the reciprocating slide groove 38. When the incomplete gear 361 rotates and meshes with the lower side of the reciprocating gear frame 360, it drives the reciprocating gear frame 360 to move in the opposite direction, so that the reciprocating gear frame 360 repeats in this way, realizing the continuous and stable reciprocating movement of the pressing roller 32. The reciprocating movement of the pressing roller 32 can repeatedly press the edge sealing strip 100, avoiding poor adhesion in some parts of the edge sealing strip 100, and further improving the uniformity and firmness of the edge sealing.
[0057] The rotational speed of motor 362 can be flexibly adjusted according to the overall processing speed, ensuring that the reciprocating pressing frequency matches the material moving speed, thus achieving continuous and efficient processing.
[0058] Before the edge banding strip 100 is bonded to the board, it needs to be softened, as shown below: Looking back Figure 5 and Figure 7As shown, the softening section 2 is specifically composed of two heating rollers 20 symmetrically arranged inside the processing frame 30. The two heating rollers 20 clamp the edge banding strip 100 in the middle position by rotating relative to each other. By adopting a targeted heating method, the edge banding strip 100 is directly and uniformly heat-conducted, thereby achieving flexible softening of the edge banding strip 100. This method abandons the unreasonable heating method of traditional equipment for thick plates, greatly improves heating efficiency, and reduces heat loss.
[0059] The heating roller 20 is equipped with a stable heating element (known structure) and adopts a high-efficiency electric heating wire heating method. After being powered on, it generates uniform heat and quickly conducts it to the surface of the roller body, heating the edge sealing strip 100 through thermal radiation and thermal conduction.
[0060] The rotation speed of the heating roller 20 is synchronized with the moving speed of the board and the conveying speed of the edge banding strip 100. This not only clamps and conveys the edge banding strip 100, but also ensures that all parts of the edge banding strip 100 are heated evenly and softened consistently.
[0061] The working temperature of the heating roller 20 can be flexibly adjusted according to the material and thickness of the edge banding strip 100, adapting to the softening requirements of different types of edge banding strips 100, ensuring the best softening effect, and further improving the edge banding bonding quality.
[0062] In addition, after heating the edge banding strip 100, it is also necessary to limit the board to prevent the board from shifting during the reciprocating pressing of the pressure roller 32, as shown below: Reference Figure 3 As shown, the processing frame 30 is also equipped with a limiter 4 for both edge sealing and drilling positioning of the board. The limiter 4 includes two limit swing arms 40 that are symmetrically connected by a torsion spring in the height direction of the processing frame 30. A limit roller 41 is rotatably installed at the end of the limit swing arm 40 away from the processing frame 30. By adjusting the angle of the limit swing arm 40, the limit roller 41 is made to abut against the board, thus ensuring the edge sealing and drilling position accuracy.
[0063] When the board enters the processing area, the two limiting swing arms 40, driven by torsion springs, drive the limiting rollers 41 to approach the surface of the board, so that the limiting rollers 41 roll stably against the upper and lower surfaces of the board. During the movement of the board, the limiting rollers 41 roll synchronously with the board, which can provide continuous and stable limiting constraints for the board, preventing problems such as up-and-down shaking, left-and-right deviation, and swaying during processing, and also avoid rigid limiting scratches, pressure marks, and bumps on the surface of the board.
[0064] By relying on the torsion spring to drive the limit arm 40 to adaptively adjust the rotation angle, the contact position of the limit roller 41 can be precisely controlled, so that the side of the board edge sealing is precisely aligned with the pressing roller 32 and the drilling drill 34, while taking into account the edge sealing clamping accuracy and the drilling position accuracy.
[0065] Let's look again. Figure 3 As shown, the limiting swing arm 40 is a telescopic structure, including a fixed arm 42 and a telescopic arm 43. Both have a common telescopic hole, and a locking screw 44 is provided in the telescopic hole. By telescopic adjustment, it can adapt to the coaxiality requirements of edge sealing and drilling of different thickness plates.
[0066] After adjusting the extension length of the telescopic arm 43 according to the thickness of the sheet material, insert the locking screw 44 into the corresponding telescopic hole and tighten it to securely lock the fixed arm 42 and the telescopic arm 43, ensuring that the length of the limiting arm 40 remains stable. The structural design of the telescopic limiting arm 40 allows the device to flexibly adapt to the processing needs of sheet materials of different thicknesses. Whether it is a thin sheet material or a thick sheet material, precise limiting can be achieved by quickly adjusting the length of the limiting arm 40.
[0067] Reference Figure 5 As shown, a support frame 60 is also installed on the side wall of the processing frame 30. The frame is equipped with an adhesive spray nozzle 61 for spraying adhesive onto the edge sealing strip 100, and an anti-diffusion plate 62 for protecting the edge sealing strip 100 and preventing the adhesive from spreading. The anti-diffusion plate also blocks the drilling station to prevent the edge sealing adhesive from contaminating the hole wall.
[0068] The support frame 60 is equipped with an adhesive nozzle 61, which is connected to an external adhesive supply system through a delivery pipe. The adhesive supply system can precisely control the amount and speed of adhesive spraying to ensure uniform spraying of adhesive and avoid waste and pollution caused by excessive adhesive or weak sealing due to insufficient adhesive.
[0069] The adhesive nozzle 61 is precisely aligned with the bonding surface between the edge banding strip 100 and the side wall of the board. During the processing, the adhesive nozzle 61 sprays special edge banding adhesive evenly onto the bonding surface to ensure that the edge banding strip 100 is firmly bonded to the side wall of the board without peeling or curling.
[0070] The anti-diffusion plate 62 has a dual protective function. On the one hand, it protects the edge banding strip 100 and the processing area, preventing the adhesive sprayed by the adhesive nozzle 61 from spreading and splashing into the non-processing area. On the other hand, it blocks the drilling station, effectively preventing debris from splashing onto the edge banding adhesive during the adhesive spraying and drilling process.
[0071] Reference Figure 8 , Figure 9 and Figure 10 As shown, specifically, after the board and the edge banding strip 100 are bonded together, the board is always in a moving state. When the board moves a specified distance, it stops moving, and at this time, it needs to be drilled.
[0072] The drilling drill 34 is equipped with a processing unit 7 that works in conjunction with the edge sealing pressing action. The processing unit 7 includes an execution groove 70 on the C-shaped fixing frame 35. Symmetrical fixing plates 71 are slidably installed in the execution groove 70 of the C-shaped fixing frame 35. Two clamping plates 72 are symmetrically installed in the height direction of the C-shaped fixing frame 35. A linkage rack 73 is installed on the fixing plate 71. The clamping plate 72 is provided with a serrated structure. A linkage gear 74 rotatably installed on the C-shaped fixing frame 35 meshes between the clamping plate 72 and the linkage rack 73. The clamping plate 72 can position the edge sealing strip 100 to prevent it from shaking or detaching from the board.
[0073] The processing unit 7 works in synergy with the edge sealing and pressing action, which not only enables hole wall trimming but also further strengthens the interlocking of edge sealing and drilling actions.
[0074] Reference Figure 10 As shown, the U-shaped fixing frame 35 has two clamping plates 72 symmetrically installed in the height direction. The two clamping plates 72, together with the fixing plate 71, can form an auxiliary clamping and positioning for the edge banding strip 100, further ensuring that the edge banding strip 100 does not shift or move during the drilling process, fully constraining the position of the edge banding strip 100 and resisting the influence of drilling torque.
[0075] A linkage rack 73 is fixedly installed on the fixed plate 71. The linkage rack 73 extends along the length of the fixed plate 71. The rack tooth profile is optimized to ensure tight meshing with the linkage gear 74 and smooth transmission. The clamping plate 72 is provided with a serrated structure, which can mesh with the linkage rack 73 together with the linkage gear 74. The linkage gear 74 is rotatably installed on the inner wall of the C-shaped fixing frame 35 through a wheel axle. A bearing is provided between the wheel axle and the C-shaped fixing frame 35 to reduce rotational friction resistance and ensure smooth gear rotation.
[0076] Only when the pressing roller 32 completes the edge sealing and pressing action, driving the protruding block 33 to move, and driving the C-shaped fixing frame 35 to be adjusted into place through the linkage rod 36, can the clamping plate 72 position the edge sealing strip 100 under the action of the linkage structure. After the clamping plate 72 is positioned, its serrated structure drives the linkage gear 74 to rotate, and the linkage gear 74 then drives the linkage rack 73 and the fixing plate 71 to move. At this time, the drilling drill 34 can start the drilling operation. If the edge sealing and pressing action is not completed, the drilling drill 34 cannot be started, avoiding the risk of accidentally starting the drilling during edge sealing.
[0077] Meanwhile, during the drilling process, the clamping plate 72 maintains the positioning of the edge banding strip 100, and the fixing plate 71 also positions the board material simultaneously, further constraining the position of the edge banding strip 100, resisting the impact of the drilling torque, and preventing the edge banding strip 100 from opening or shifting unexpectedly.
[0078] Reference Figure 10As shown, two suction frames 80 are also installed on the fixed plate 71. The internal suction channels are designed with negative pressure suction channels and are connected to external suction equipment through connecting pipes. This provides stable negative pressure to the external suction equipment and achieves efficient collection of processing debris through negative pressure adsorption. The suction frames 80 move synchronously with the fixed plate 71 and always maintain precise correspondence with the drilling station and the edge sealing and pressing station to ensure that the suction position is completely matched with the location where the debris is generated, thereby improving the suction collection effect.
[0079] The inner side of the dust collection frame 80 is provided with several collection holes 81 at equal intervals, so that debris can enter the dust collection frame 80 smoothly and avoid the debris from clogging the collection holes 81.
[0080] During work: The first step is to place the material to be processed stably on the strip processing area of the processing platform 1. Adjust the extension length of the limiting swing arm 40 according to the thickness of the material. After the adjustment is completed, tighten the locking screw 44 to fix it, ensuring that the limiting roller 41 can stably contact the surface of the material to achieve precise positioning.
[0081] Step 2: Adjust the working temperature of the heating roller 20 according to the material and thickness of the edge banding strip 100 to ensure that the edge banding strip 100 can be fully softened to meet the corner edge banding requirements; adjust the speed of the control motor 362, the conveying speed of the unwinding roller 31 and the rotation speed of the heating roller 20 according to the overall processing rhythm to ensure that the actions of each component are coordinated and consistent.
[0082] Step 3: Start the bidirectional electric telescopic rod 50 to drive the wave-shaped clamping plate 72 to tension and position the edge banding strip 100, and complete the equipment debugging and preparation work. At this time, the edge banding and punching mechanism of the device is in the standby state. Only after the above preparation work is completed can the subsequent processing action be started to form the initial safety interlock.
[0083] Step 4: Start the equipment and the board moves forward at a constant speed along the strip processing area. First, it enters the softening section 2 area. Two symmetrically rotating heating rollers 20 uniformly heat and soften the edge banding strip 100. After softening, the edge banding strip 100 continues to move with the board into the integrated processing section 3 area. The adhesive nozzle 61 uniformly sprays adhesive onto the bonding surface between the edge banding strip 100 and the side wall of the board. The anti-diffusion plate 62 simultaneously blocks the diffusion and contamination of the adhesive, ensuring that the adhesive accurately covers the bonding surface and improves the bonding strength. Under the action of the adaptive compression spring 37 and the switching electric control rod 9, the pressing roller 32 achieves adaptive pressing according to the actual state of the board. At the same time, it controls the motor 362 to drive the incomplete gear 361 to rotate. Through meshing transmission, it drives the reciprocating tooth frame 360 and the pressing roller 32 to move back and forth along the reciprocating slide groove 38, and uniformly presses the edge banding strip 100 in a cyclic manner, so that the edge banding strip 100 is tightly and stably bonded to the side wall of the board, enhancing the torsional resistance of the edge banding structure.
[0084] Step 5: When the corner of the board needs to be processed, the external robot controls the board to rotate and re-enter the processing area for edge sealing. The fully softened edge sealing strip 100 can ensure the quality of edge sealing under the cyclic pressing action of the pressing roller 32.
[0085] Step 6: When drilling is required, the protrusion 33 moves away from the board. At this time, under the action of the linkage 36, the drilling drill 34 and the C-shaped fixing frame 35 approach the board. At this time, the fixing plate 71 and the clamping plate 72 on the C-shaped fixing frame 35 position the board and the edge banding strip 100. Then the drilling drill 34 begins to extend and retract to drill holes.
[0086] The embodiments described herein are preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape, and principle of the present invention should be covered within the scope of protection of the present invention.
