Description

Technical Field

[0001] This invention relates to the field of sheet metal processing equipment technology, specifically to a sheet metal synchronous embossing processing equipment. Background Technology

[0002] In short-cycle lamination processes, a press is often used to press paper onto the surface of particleboard or medium-density fiberboard to achieve decoration and simultaneous embossing of the board. Existing lamination equipment usually includes a hot press plate and a conveyor line. The working process is as follows: the board with impregnated paper is sent into the hot press area, and the impregnated paper is cured and bonded to the surface of the board by the high temperature and high pressure of the hot press plate.

[0003] However, in actual production, it has been found that due to the increased fluidity of the impregnated paper after heating during the hot pressing process, coupled with the high pressure, some of the impregnated paper often protrudes from the edges of the board. The hot press plates of existing equipment are mostly planar structures, which lack effective physical constraints on the protruding impregnated paper during hot pressing. After hot pressing, when the hot press plate is lifted up and removed from the board, the protruding impregnated paper is prone to curling and warping due to its own stress or airflow disturbance, as it is no longer restrained and has not been fully cured. This not only affects the aesthetics of the board edges but also causes the impregnated paper to peel off in subsequent processes, reducing the yield rate of finished products. Therefore, a board synchronous embossing processing equipment is proposed to solve the above problems. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a synchronous embossing processing device for sheet materials, which solves the problem that when the hot press plate is lifted upwards and detached from the sheet material, the impregnated paper with protruding edges is prone to curling and warping due to its own stress or airflow disturbance because it is no longer restrained and has not yet fully cured.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a synchronous embossing processing equipment for sheet metal, comprising a conveyor line, a stacking release device at the top of the conveyor line, a sheet metal transfer device on the outside of the stacking release device, a paper guide frame on the outside of the sheet metal transfer device, two upper pressing mechanisms on the outside of the paper guide frame, a bottom suction assembly at the bottom of the conveyor line, a hot pressing assembly on the outside of the conveyor line, an anti-warping mechanism at the bottom of the hot pressing assembly, and an auxiliary mechanism on the outside of the hot pressing assembly;

[0006] The anti-warping mechanism includes a hot press plate. The top end of the hot press plate is fixedly connected to the bottom end of the hot press assembly. Multiple baffles are provided on the outer side of the hot press plate. A rotating ring is fixedly connected to the top end of each of the multiple baffles. A hollow base ring is provided on the outer side of the rotating ring. A guide ring is fixedly connected inside the rotating ring. A button is slidably connected inside the guide ring. A locking ring is fixedly connected to the outer side of the button.

[0007] Preferably, the pressing mechanism includes a cylinder, which is disposed on the outside of the paper guide frame. An upper support plate is fixedly connected to the driving end of the cylinder. An elastic component is disposed at the bottom end of the upper support plate. A lower support plate is disposed at the bottom end of the elastic component. A pressing head is fixedly connected to the bottom end of the lower support plate.

[0008] Preferably, the elastic component includes a fixed cylinder, the top end of which is fixedly connected to the bottom end of the upper support plate, a central rod is slidably connected inside the fixed cylinder, a base is fixedly connected to the bottom end of the central rod, and the bottom end of the base is fixedly connected to the top end of the lower support plate.

[0009] Preferably, a spring is sleeved on the outer side of the fixed cylinder, one end of the spring abutting against the bottom end of the upper support plate, and the other end of the spring abutting against the bottom end of the lower support plate.

[0010] Preferably, the bottom suction assembly includes a negative pressure platform, the outer side of which is disposed at the bottom end of the conveyor line, an air pump is disposed at the bottom end of the negative pressure platform, and multiple micro-holes are opened at the top end of the negative pressure platform.

[0011] Preferably, a second spring is sleeved on the inner wall of the retaining ring, one end of the second spring abutting against the inner wall of the button, and the other end of the second spring abutting against the inner wall of the hollow base ring.

[0012] Preferably, the outer side of the hollow base ring is fixedly connected to the outer side of the hot press plate, and the outer side of the retaining ring is slidably connected to the inner wall of the hollow base ring.

[0013] Preferably, the outer side of the locking ring is provided with multiple locking rods, and the outer side of the rotating ring is provided with locking holes that fit with the multiple locking rods.

[0014] Preferably, the auxiliary mechanism includes a crossbeam, the outer side of which is fixedly connected to the outer side of the hot pressing assembly. Two side beams are fixedly connected to the bottom end of the crossbeam. Pressure rollers are rotatably connected inside the two side beams. Pressure blocks are provided inside the two side beams. The bottom end of the pressure block contacts the outer side of the pressure roller. A top column is fixedly connected to the top end of the pressure block.

[0015] Preferably, a spring three is sleeved on the outer side of the top column, one end of the spring three abuts against the inner wall of the pressure roller, and the other end of the spring three abuts against the top of the pressure block.

[0016] This invention provides a synchronous embossing processing device for sheet metal. It has the following beneficial effects:

[0017] 1. This invention uses adjustable baffles around the top of a hot press plate. Once adjusted, the baffles and the hot press plate plane form a closed limiting structure similar to a cover. Pressing the button inward causes it to move into the hollow base ring under the guidance of the guide ring. Simultaneously, the button drives the locking ring to move into the hollow base ring and compress the second spring. After the angle is adjusted, releasing the button allows the second spring to return to its initial position, and the locking ring locks the rotating ring. During the hot pressing process, this constrains the resin-impregnated paper protruding from the edges of the board, preventing the resin-impregnated paper from curling under high temperature and pressure, thus ensuring the processing quality of the board edges.

[0018] 2. This invention provides a support frame consisting of a crossbeam and side beams at the discharge end of the hot pressing assembly. The pressure roller is stably installed on the frame, forming an elastic adaptive pressing structure with the pressure block, top column, and spring. During the critical window period of resin curing, the pressure roller continues to constrain and limit the resin-impregnated paper at the edge of the board. The pressure roller can flexibly adjust the pressing force according to the thickness deviation of the board, while pushing outward and expelling air bubbles generated between the resin-impregnated paper and the board during the hot pressing process, thus avoiding quality defects such as weak adhesion and surface bulging caused by residual air bubbles.

[0019] 3. In this invention, the cylinder extends after starting, driving the upper support plate to move smoothly downward. The upper support plate drives the lower support plate to evenly transmit pressure to the pressure head. At the same time, the air pump in the bottom suction assembly starts to form a stable negative pressure environment inside the negative pressure platform. The negative pressure is transmitted to the lower edge of the paper through the micropores on the surface of the platform. The pressure head above and the negative pressure below form a double locking structure of upper pressure and bottom suction. At the moment the suction cup releases the resin-impregnated paper, it firmly restricts the displacement of the paper edge, prevents the paper from drifting, and ensures that the resin-impregnated paper can be accurately laid on the preset position on the surface of the board.

[0036] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Please see the appendix Figure 1 - Appendix Figure 2This invention provides a synchronous embossing processing equipment for sheet metal, including a conveyor line 1. The conveyor line 1 provides a sheet metal conveying channel for the entire equipment, ensuring that the sheet metal moves at a uniform speed according to the process sequence and ensuring synchronous processing. A stacking separator 2 is provided at the top of the conveyor line 1. The stacking separator 2 is used to separate stacked sheet metals one by one, avoiding multiple sheets overlapping and entering the work station, ensuring the accuracy of subsequent processing. A sheet metal transfer device 3 is provided on the outside of the stacking separator 2. The sheet metal transfer device 3 realizes the precise transfer of sheet metals between different conveyor lines 1, completing the work station switching before paper laying. A paper guide frame 4 is provided on the outside of the sheet metal guide frame 3. The paper guide frame 4 guides and positions the resin-impregnated paper, ensuring accurate alignment between the paper and the sheet metal, providing a basis for hot pressing and bonding. Two... The upper pressing mechanism 6 is used to press the edge of the resin-impregnated paper, suppress the drift of the paper during release, and improve the paper laying positioning accuracy. The bottom end of the conveyor line 1 is provided with a bottom suction component 7, which adsorbs the paper from below, forming a double positioning with the upper pressing mechanism 6 to further prevent the paper from shifting. The outer side of the conveyor line 1 is provided with a hot pressing assembly 5, which provides a high temperature and high pressure environment to achieve the pressing and curing of the resin-impregnated paper and the board and surface embossing. The bottom end of the hot pressing assembly 5 is provided with an anti-curling mechanism 8, which constrains the edge of the board during hot pressing to prevent the resin-impregnated paper from curling at high temperature and ensure edge quality. The outer side of the hot pressing assembly 5 is provided with an auxiliary mechanism 9, which continues to constrain the edge of the board after hot pressing to consolidate the curing effect, remove air bubbles, and avoid bulging.

[0038] Please see the appendix Figure 7 - Appendix Figure 9 The anti-warping mechanism 8 includes a hot press plate 81, which provides a high-temperature and high-pressure working surface for the hot press assembly 5, ensuring clear embossing and sufficient adhesion and curing. The top of the hot press plate 81 is fixedly connected to the bottom of the hot press assembly 5. This fixed connection ensures stable operation of the hot press plate 81 and uniform pressure transmission. Multiple baffles 82 are provided on the outer side of the hot press plate 81. The baffles 82 are used to constrain the edges of the board and limit the warping and curling of the resin-impregnated paper during hot pressing, thereby improving the edge processing quality. Rotating rings 84 are fixedly connected to the top of each of the multiple baffles 82. The rotating rings 84 drive the baffles 82 to rotate synchronously, realizing continuous adjustment of the angle of the baffles 82 to adapt to different specifications of boards. A hollow base ring 83 is provided on the outer side of the rotating ring 84. The hollow base ring 83 provides support and installation foundation for the rotating ring 84, ensuring rotation and positioning. A guide ring 86 is fixedly connected inside the rotating ring 84. The guide ring 86 provides linear guidance for the button 87.

[0039] A button 87 is slidably connected inside the guide ring 86. The button 87 serves as the unlocking actuator, offering convenient operation and enabling quick unlocking with angle adjustment. A retaining ring 85 is fixedly connected to the outside of the button 87. The retaining ring 85 moves synchronously with the button 87, locking and releasing the rotating ring 84. A second spring 88 is fitted inside the retaining ring 85, providing a reset force. Releasing the button 87 automatically locks the ring, ensuring efficient operation. One end of the second spring 88 abuts against the inner wall of the button 87, and the other end abuts against the inner wall of the hollow base ring 83, ensuring stable contact and guaranteeing the reset force. The hollow base ring 83 is fixedly connected to the outer side of the hot press plate 81. The fixed installation ensures the overall structure is stable and does not shift during the hot pressing action. The outer side of the locking ring 85 is slidably connected to the inner wall of the hollow base ring 83. The sliding fit ensures that the locking ring 85 moves smoothly and locks and unlocks quickly. The outer side of the locking ring 85 is provided with multiple locking rods, which are used to insert into the locking holes to achieve positioning. The locking is firm and not easy to loosen. The outer side of the rotating ring 84 is provided with locking holes that match the multiple locking rods. The locking holes and locking rods are precisely matched to achieve multi-level positioning of the baffle 82 angle to meet different processing requirements.

[0040] Please see the appendix Figure 3 - Appendix Figure 5 The pressing mechanism 6 includes a cylinder 61, which provides a stable driving force for the pressing action and ensures smooth pressing. The cylinder 61 is located on the outside of the paper guide frame 4, with a reasonable installation position that does not interfere with paper feeding and guiding operations. The driving end of the cylinder 61 is fixedly connected to an upper support plate 62, which bears the pressure of the cylinder 61 and evenly transmits it to the lower elastic component to ensure balanced pressure distribution. An elastic component is provided at the bottom of the upper support plate 62, which provides flexible pressure buffer to avoid damage to the paper surface by rigid pressing and ensures gentle pressure application. A lower support plate 63 is provided at the bottom of the elastic component, which evenly transmits the elastic pressure to the pressure head 64. The pressure head 64 is fixedly connected to the bottom of the lower support plate 63, which directly acts on the edge of the resin-impregnated paper to achieve paper positioning and pressing, and suppress drift.

[0041] Please see the appendix Figure 5The elastic component includes a fixed cylinder 65, which provides a sliding guide for the central rod 66, ensuring that the elastic extension and contraction direction is stable and does not deviate. The top end of the fixed cylinder 65 is fixedly connected to the bottom end of the upper support plate 62, and the fixed connection ensures reliable force. The central rod 66 is slidably connected inside the fixed cylinder 65, and the central rod 66 slides along the axial direction of the fixed cylinder 65, forming an elastic buffer with the internal air pressure. The bottom end of the central rod 66 is fixedly connected to a base 67, which expands the force-bearing area, making the pressure transmission more uniform and protecting the lower support plate 63. The bottom end of the base 67 is fixedly connected to the top end of the lower support plate 63, and the connection is firm, ensuring stable output of elastic pressure. A spring 68 is sleeved on the outside of the fixed cylinder 65. The spring 68 assists in providing elastic pressure, enhances the buffering effect, and makes the clamping force more gentle and uniform. One end of the spring 68 abuts against the bottom end of the upper support plate 62, and the other end of the spring 68 abuts against the bottom end of the lower support plate 63. The two ends abut stably, ensuring the elastic force.

[0042] Please see the appendix Figure 6 The bottom suction component 7 includes a negative pressure platform 72, which provides a closed negative pressure space for bottom suction, ensuring continuous and stable suction force. The outer side of the negative pressure platform 72 is set at the bottom end of the conveyor line 1, and the installation position is directly opposite the paper laying area, corresponding vertically to the upper pressure mechanism 6, which improves the positioning effect. An air pump 71 is set at the bottom end of the negative pressure platform 72, which provides a stable negative pressure source for the negative pressure platform 72, ensuring sufficient suction force. Multiple microholes 73 are opened at the top of the negative pressure platform 72. The multiple microholes 73 are evenly distributed, so that the negative pressure is evenly applied to the lower surface of the paper, and the suction is stable.

[0043] Please see the appendix Figure 10 - Appendix Figure 11The auxiliary mechanism 9 includes a crossbeam 91, which provides top support for the auxiliary mechanism 9 to ensure the stability of the overall structure. The outer side of the crossbeam 91 is fixedly connected to the outer side of the hot pressing assembly 5. The fixed installation ensures that the auxiliary mechanism 9 and the hot pressing assembly 5 operate synchronously. Two side beams 92 are fixedly connected to the bottom end of the crossbeam 91. The side beams 92 provide installation support for the pressure rollers 93, ensuring that the pressure rollers 93 are installed firmly and rotate smoothly. The pressure rollers 93 are rotatably connected inside the two side beams 92. The pressure rollers 93 continuously constrain the edges of the board to prevent the resin-impregnated paper from curling and to remove air bubbles. The pressure blocks 94 are provided inside the two side beams 92. The elastic pressure is transmitted to the surface of the pressure roller 93 to ensure the clamping force. The bottom end of the pressure block 94 is in close contact with the outer side of the pressure roller 93 to ensure effective pressure transmission and adaptive fit to the surface of the board. The top end of the pressure block 94 is fixedly connected to the top post 95, which provides guidance and support for the pressure block 94 to ensure stable pressure direction. A spring 96 is sleeved on the outer side of the top post 95. The spring 96 provides adaptive elastic pressure and can automatically adjust the clamping force according to the thickness of the board, with strong adaptability. One end of the spring 96 abuts against the inner wall of the pressure roller 93, and the other end of the spring 96 abuts against the top end of the pressure block 94. The two ends are stably abutted to ensure elastic clamping force.

[0044] Working principle: The boards to be processed are conveyed in an orderly manner by conveyor line 1. When the boards are conveyed to the stacking separator 2, the stacking separator 2 separates the stacked boards one by one to avoid multiple boards sticking together and entering the processing station at the same time. Then, the separated single boards are accurately conveyed to the board positioner 3. The board positioner 3 transfers the boards to another conveyor line 1 to wait for the resin impregnated paper to be laid. Then, through the paper guide frame 4, the paper guide frame 4 positions the resin impregnated paper and simultaneously completes the guidance and bonding of the resin impregnated paper, ensuring that the relative position between the board and the resin impregnated paper is accurate and laying a solid positioning foundation for subsequent hot pressing and bonding processing.

[0045] At the paper-laying station, addressing the issue of paper drifting during the release of the paper in the commonly used automatic paper-laying mode (from suction to translation to release), the equipment uses an upper pressure mechanism 6 to press the edges of the paper firmly, restricting its displacement. During laying, the cylinder 61 installed at the paper guide frame 4 extends and drives the upper support plate 62 to move smoothly downwards. The upper support plate 62 transmits power and pressure to the lower support plate 63, which further evenly transmits the pressure to the pressure head 64. An elastic component is provided between the upper support plate 62 and the lower support plate 63. During the downward pressing process, the upper support plate 62 moves the fixed cylinder 65 and the base 67 closer together, causing the central rod 66 fixed at the top of the base 67 to continuously move into the fixed cylinder 65 filled with compressed gas. This, combined with the spring 68, assists in applying elastic pressure to the resin-impregnated paper. Finally, the upper pressure mechanism 6 restricts the edges and corners of the resin-impregnated paper, preventing drifting.

[0046] In addition, a bottom suction component 7 is installed at the bottom of the paper laying station to generate a stable suction force on the lower edge of the paper. Together with the pressure head 64 above, it forms a double locking structure of upper pressure and bottom suction, which enhances the positioning stability at the moment of paper release, prevents paper drift, and ensures that the resin-impregnated paper can be laid in the preset position on the board surface. After the air pump 71 is started, a stable negative pressure environment is formed inside the negative pressure platform 72. The negative pressure is transmitted to the lower edge of the paper through the micropores 73 on the surface of the platform.

[0047] After the resin-impregnated paper is laid, the board is fed into area 5 of the hot pressing assembly. The board is then hot-pressed by the hot pressing plate 81. Adjustable baffles 82 are installed around the top of the hot pressing plate 81. Once adjusted, the baffles 82 and the flat surface of the hot pressing plate 81 cooperate to form a closed, cap-like limiting structure. During the hot pressing process, this structure restrains the protruding resin-impregnated paper around the edges of the board, preventing it from curling or warping under high temperature and pressure. To ensure the processing quality of the board edge, by pressing button 87 inward, button 87 moves into the hollow base ring 83 under the guidance of guide ring 86. At the same time, button 87 drives the locking ring 85 to move into the hollow base ring 83 and squeeze spring 2 88. Multiple locking rods on the outside of locking ring 85 disengage from rotating ring 84, allowing rotating ring 84 to be unlocked and rotated. After the angle is adjusted, button 87 is released, allowing spring 2 88 to return to the initial position of anti-warping mechanism 8, and locking ring 85 locks rotating ring 84. Combined with the high-temperature heating effect of hot press plate 81, high-temperature and high-pressure bonding and curing of resin impregnated paper and board are achieved, while synchronous embossing processing of the board surface is completed, ensuring clear embossing and firm adhesion.

[0048] When the hot press plate 81 completes the hot pressing process and begins to lift upwards, the adjustable angle baffle 82 that works with it gradually separates from the edge of the board. Since the baffle 82 limits and constrains the edge of the board during the hot pressing process, the board will continue to be conveyed backwards after the hot pressing is completed. In order to prevent the hot press plate 81 and the baffle 82 from separating too early, which would cause the resin-impregnated paper at the edge of the board to curl and deform due to loss of constraint, an auxiliary mechanism 9 is provided at the discharge end of the hot pressing assembly 5. During the critical window period of resin curing, the pressure roller 93 in the auxiliary mechanism 9 continues to constrain and limit the resin-impregnated paper at the edge of the board. The pressure roller 93 is stably installed on the support frame formed by the crossbeam 91 and the side beam 92. Together with the pressure block 94, the top column 95 and the spring 96, it forms an elastic adaptive pressing structure that can flexibly adjust the pressing force according to the thickness deviation of the board. While continuously constraining the edge of the board and preventing edge warping, it can also push outward and expel the air bubbles generated between the resin-impregnated paper and the board during the hot pressing process, avoiding quality defects such as weak adhesion and surface bulging caused by residual air bubbles.

[0049] Finally, the qualified boards that have completed the embossing are conveyed out of the equipment by conveyor line 1 and then transported and stacked by the final board transponder 3.
