Description

Technical Field

[0001] This invention relates to the field of furniture board edge banding technology, specifically to a formaldehyde-free edge banding device and control system for furniture boards. Background Technology

[0002] Formaldehyde-free edge banding for furniture panels typically uses laser edge banding machines. The back of the edge banding strip contains a photosensitive absorption layer (such as carbon black or a special polymer). When irradiated by a high-energy laser, this layer rapidly heats up and conducts heat, causing the photosensitive absorption layer of the edge banding substrate to partially melt. The molten photosensitive absorption layer then bonds to the edge of the panel at the molecular level under pressure, forming a strong bond after cooling.

[0003] Existing formaldehyde-free edge banding devices for furniture boards typically use multiple rollers to compress the edge banding strip and fix it to the furniture board. These rollers usually apply varying pressures to the edge banding to improve stability. However, the pressure of each roller is typically adjusted individually, resulting in a complex structure that is difficult to synchronize. Furthermore, the cooling rate of the molten photosensitive absorption layer affects the crystal structure and internal stress distribution. Excessive cooling can lead to microcracks, while insufficient cooling disrupts production rhythm. In existing formaldehyde-free edge banding devices, the contact area between the air-cooled layer and the edge banding strip during compression is limited due to roller obstruction, reducing cooling efficiency. To address these issues, a formaldehyde-free edge banding device and control system for furniture boards is proposed. Summary of the Invention

[0008] Furthermore, the adjustment component includes: An adjusting frame is fitted onto the side wall of the connecting rod. The side wall of the adjusting frame has a second through groove for fitting the connecting rod, so that the adjusting frame can move and deflect on the side wall of the connecting rod.

A third adjusting plate is fixedly positioned on the side of the first and second adjusting plates away from the adjusting frame. An electric push rod is fixedly positioned on the top of the mounting plate, and the telescopic shaft of the electric push rod is fixedly connected to the side of the third adjusting plate away from the adjusting frame.

[0009] Furthermore, the deflection component includes: A limiting seat is fixedly installed on the inner side of the third adjusting plate. A first groove is provided on the side of the limiting seat away from the third adjusting plate. A second groove is provided on the inner wall of the first groove. The inner wall diameter of the second groove is larger than the inner wall diameter of the first groove. A first electromagnet is fixedly disposed on the inner wall of a second groove, and the inner wall of the second groove is fitted with a second electromagnet.

[0010] Furthermore, the deflection component also includes: The limiting rod is fixed on the side of the second electromagnet away from the first electromagnet and extends outside the limiting seat. The end of the limiting rod away from the second electromagnet is hinged to the side of the adjusting frame near the electric push rod.

The side wall of the limiting rod located in the second groove is sleeved with a second spring, and the second spring is located on the side of the second pressure sensor away from the second electromagnet.

[0011] Furthermore, a space is left between the extrusion block and the second fixed plate for the adjustment frame to move and deflect.

[0013] The present invention also provides a control system for a formaldehyde-free edge banding device for furniture boards.

The output terminal of the data acquisition module is connected to the input terminal of the processing module, and the output terminal of the processing module is connected to the input terminals of the control module and the display module.

[0014] This invention provides a formaldehyde-free edge-sealing device and control system for furniture panels. Compared with the prior art, it has the following advantages: 1. This invention uses an extrusion component and an adjustment component to enable multiple extrusion cylinders to simultaneously extrude the edge banding strip. After the functional layer melts, the edge banding strip is fixed to the side of the furniture board by extrusion, improving the edge banding effect. Furthermore, by using the adjustment component and the deflection component, the extrusion cylinders at different positions apply different extrusion forces to different positions of the edge banding strip, gradually increasing the extrusion force on the edge banding strip during the edge banding process, thereby improving the edge banding effect.

[0015] 2. This invention gradually increases the pressure on the edge sealing strip by using multiple extrusion cylinders, thereby improving the edge sealing effect. It also facilitates the simultaneous adjustment of the positions of the multiple extrusion cylinders, making it convenient for practical operation. The second pressure sensor determines the force by which the second electromagnet compresses the second spring, so as to control the force applied by the two deflection components to both sides of the adjustment frame, which is convenient for actual adjustment and use. By designing the extrusion block in an arc shape, the adjusting frame can contact the extrusion block when it is extruded at different angles, thus facilitating the synchronous movement of multiple extrusion blocks and improving the stability of the extrusion cylinder.

[0016] 3. This invention monitors the pressure exerted by the extrusion block and extrusion cylinder on the edge sealing strip using a first pressure sensor in the monitoring component. This allows for adjustment of the position and angle of the adjustment frame based on actual conditions, thereby adjusting the pressure exerted by the extrusion cylinder on the edge sealing strip. Furthermore, it facilitates monitoring the pressure exerted by a single extrusion cylinder on the edge sealing strip, enabling adjustments based on the actual edge sealing situation. Additionally, the extrusion block applies pressure to the first pressure sensor via a drive retaining ring, improving the accuracy of pressure monitoring.

[0017] 4. In this invention, multiple extrusion cylinders contact the edge sealing strip sequentially and cooperate with a cooling mechanism to deliver coolant at different temperatures within the multiple extrusion cylinders, thereby performing gradient cooling on the functional layer inside the edge sealing strip and improving the cooling effect. By circulating the coolant in the guide channel, the cooling effect is improved. Furthermore, through the design of fluid slip rings, the functional layer inside the sealing strip is cooled while the extrusion cylinder can rotate, thus not affecting the connection between the first guide tube and the guide tube. By controlling the pressure of the coolant in the guide channel, the rigidity of the extrusion cylinder is controlled, thereby enabling the extrusion cylinder to stably extrude the edge sealing strip while facilitating the adjustment of the contact area between the extrusion cylinder and the edge sealing strip according to the actual situation, thus facilitating actual cooling.

[0020] The technical solutions of 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.

[0021] Example 1, please refer to Figures 1-6 A formaldehyde-free edge-sealing device for furniture panels includes a machine tool 1, a top plate 4 fixedly mounted on the top of the machine tool 1, and a conveying mechanism 2 disposed inside the machine tool 1 and the top plate 4. The conveying mechanism 2 conveys the furniture panel 3 by contacting its top and bottom. Simultaneously, it limits the movement of the top and bottom of the furniture panel 3 to prevent vertical movement. A positioning mechanism is also provided on the back of the machine tool 1 to position the furniture panel 3 from the side away from the edge-sealing mechanism 5. Limiting the movement of furniture board 3 after being squeezed by edge banding mechanism 5, thus facilitating subsequent edge banding, can be achieved by using multiple rollers that can move up and down synchronously to limit the top of furniture board 3. These rollers can also rotate, limiting the movement of furniture board 3 without affecting its conveying. Alternatively, a positioning mechanism can use horizontally movable rollers to limit the side of furniture board 3 away from edge banding mechanism 5, and these rollers can also rotate, thereby restricting the movement of furniture board 3 after being squeezed by edge banding mechanism 5. All of the above are existing technologies and are not shown in the figure, so they will not be elaborated here.

[0022] The formaldehyde-free edge banding device for furniture boards also includes an edge banding mechanism 5 disposed on the side wall of the machine tool 1 for pressing the edge banding strip onto the side of the furniture board 3. The edge banding mechanism 5 includes: Mounting plate 51 is fixedly mounted on the side wall of machine tool 1. The top of mounting plate 51 is provided with extrusion components 55 and monitoring components 53 arranged at intervals for extruding the edge banding strip and monitoring the extrusion force during the extrusion process. Cooling components 54 are provided at the top and bottom of extrusion components 55. An adjusting component 56 is disposed on the top of the machine tool 1. Deflection components 52 are disposed on both sides of the adjusting component 56 and on both sides of the monitoring component 53. The adjusting component 56 and the deflection components 52 cooperate to synchronously adjust the pressure exerted by the spaced-apart extrusion components 55 on the edge sealing strip. The extrusion components 55 include: The first fixing plate 551 is fixedly mounted on the top of the mounting plate 51 and has a bent design. The inner sides of both the first fixing plate 551 and the mounting plate 51 are provided with first sliding grooves 554. The inner walls of the first sliding grooves 554 are provided with first through grooves 556. The two first through grooves 556 extend to the top of the first fixing plate 551 and the bottom of the mounting plate 51, respectively.

[0023] In the implementation of this invention, the furniture board 3 requiring edge banding is moved along the length of the machine tool 1 by the conveying mechanism 2. At the same time, the edge banding strip is conveyed along the side of the furniture board 3, so that the edge banding strip adheres to the side of the furniture board 3. For example, the edge banding strip adheres to the side of the furniture board 3 during the unwinding process. During this process, a high-energy laser is focused on the pre-coated functional layer on the inner side of the edge banding strip through a reflector, thereby quickly melting the extremely thin functional layer on the inner side of the edge banding strip. As the edge banding strip and the furniture board 3 are conveyed, the edge banding strip comes into contact with the furniture board 3, and the edge banding mechanism 5 presses the edge banding strip against the side wall of the furniture board 3, thereby sealing the edge of the furniture board 3. By pre-coating the functional layer on the inner side of the edge banding strip, formaldehyde can be effectively reduced.

[0024] The pre-coated functional layer is composed of a co-extruded thermoplastic polymer with high laser absorption, typically based on polypropylene, with added laser absorbers and adhesion promoters. This layer melts rapidly under laser irradiation, bonding to the edge of the board at the "molecular level" to achieve glue-free, seamless edge sealing. The laser emitting device, the mechanism for conveying the edge sealing strip, the edge sealing strip itself, and the pre-coated functional layer are all existing technologies and are not shown in the diagram; therefore, they will not be elaborated upon here.

[0025] When the edge sealing strip is squeezed by the edge sealing mechanism 5, the electric push rod 564 drives the third adjusting plate 565 to move. The third adjusting plate 565 drives the first adjusting plate 566, the second adjusting plate 563 and the adjusting frame 561 to move, so that the adjusting frame 561 moves along the side wall of the connecting rod 531, thereby driving the squeezing block 552, the frame 558 and the squeezing cylinder 557 to move, so that the squeezing cylinder 557 moves along the first slide groove 554 and squeezes the edge sealing strip, thereby simultaneously adjusting multiple squeezing cylinders 557 to squeeze the edge sealing strip. The angles at both ends of the adjustment frame 561 are adjusted by the deflection component 52, so that the adjustment frame 561 simultaneously squeezes multiple extrusion blocks 552 at a certain angle. This simultaneously drives multiple extrusion cylinders 557 to squeeze the edge banding strip at different positions, allowing the multiple extrusion cylinders 557 to squeeze the edge banding strip with a certain gradient of force. After the edge banding strip is attached to the side of the furniture board 3, the squeezing force on the edge banding strip gradually increases, thereby improving the edge banding effect. The simultaneous movement of multiple extrusion cylinders 557 facilitates actual operation. After the extrusion cylinders 557 squeeze the edge banding strip, they drive the retaining ring 533 and the connecting rod 531 to move. The first pressure sensor 532 determines the squeezing force of each extrusion cylinder 557 on the edge banding strip, facilitating actual adjustment and use.

[0026] While the edge banding strip is being squeezed by the extrusion cylinder 557, coolant is circulating in the guide groove 545 through the external pipes of the first conduit 541 and the second conduit 544. This cools the edge banding strip when it comes into contact with the extrusion cylinder 557. Furthermore, by having multiple extrusion cylinders 557 contact and squeeze the edge banding strip in succession, and by delivering coolant of different temperatures in different extrusion cylinders 557, the temperature gradient for cooling the inner functional layer of the edge banding strip is controlled, thereby improving the cooling effect.

[0027] Please see Figures 6-9 The extrusion assembly 55 also includes: The second slide groove 555 is formed at the top of the first fixed plate 551 and the bottom of the mounting plate 51, and is located outside the first through groove 556. The second slide groove 555 is provided with a second slider. A connecting plate 553 is fixedly provided on the side of the second slider away from the second slide groove 555. A first guide block is fixedly provided at the bottom of the connecting plate 553. A first slider is fixedly provided at the bottom of the first guide block. The first slider and the first guide block are respectively set in the first slide groove 554 and the first through groove 556. The frame 558 is fixedly mounted on one side where the two first sliders are close to each other. The side of the frame 558 away from the machine tool 1 is fixedly provided with an extrusion block 552. The side of the extrusion block 552 away from the frame 558 is arc-shaped.

[0028] The extrusion assembly 55 also includes: The rotating rod 559 is rotatably mounted on the top of one of the first guide blocks and extends to the bottom of the other first guide block. The rotating rod 559 is rotatably connected to the first slider, the first guide block and the frame 558. The extrusion cylinder 557 is fixedly sleeved on the side wall of the rotating rod 559 and located inside the frame 558. The outer wall of the extrusion cylinder 557 extends to the outer side of the frame 558.

[0029] Please see Figures 13-15 The adjustment component 56 includes: An adjusting frame 561 is fitted onto the side wall of the connecting rod 531. The side wall of the adjusting frame 561 has a second through groove 562 for fitting the connecting rod 531, so that the adjusting frame 561 can move and deflect on the side wall of the connecting rod 531. A first adjusting plate 566 is rotatably disposed at the top center of the adjusting frame 561. A second adjusting plate 563 is rotatably disposed at the bottom center of the adjusting frame 561. A third adjusting plate 565 is fixedly disposed on the side of the first adjusting plate 566 and the second adjusting plate 563 away from the adjusting frame 561. An electric push rod 564 is fixedly disposed on the top of the mounting plate 51. The telescopic shaft of the electric push rod 564 is fixedly connected to the side of the third adjusting plate 565 away from the adjusting frame 561.

[0030] In practical implementation, the electric push rod 564 is activated. The telescopic shaft of the electric push rod 564 drives the third adjusting plate 565 to move. The third adjusting plate 565 simultaneously drives the second adjusting plate 563 and the first adjusting plate 566 to move. The second adjusting plate 563 and the first adjusting plate 566 drive the adjusting frame 561 to move. Since the adjusting frame 561 is sleeved on the side wall of the connecting rod 531 through the second through groove 562, the pressing block 552 is squeezed along the side wall of the connecting rod 531 during the movement of the adjusting frame 561. After the pressing block 552 is squeezed, it drives the frame 558, the rotating rod 559 and the pressing cylinder 557 to move, so that multiple pressing cylinders 557 simultaneously squeeze the edge banding strip. Thus, after the functional layer melts, the edge banding strip is fixed to the side of the furniture board 3 by extrusion to perform edge banding.

[0031] When the rotating rod 559 and the extrusion cylinder 557 move, they drive the first slider and the first guide block to move along the first slide groove 554 and the first through groove 556 respectively, thereby limiting the movement of the extrusion cylinder 557, improving the stability of the extrusion cylinder 557 in extruding the edge sealing strip, and thus improving the stability of the edge sealing. In addition, the rotating rod 559 is rotatably connected to the first slider, so that the extrusion cylinder 557 extrudes the edge sealing strip in a rotating state, which is convenient for actual edge sealing use.

[0032] Please see Figures 14-15 The deflection component 52 includes: The limiting seat 526 is fixedly disposed on the inner side of the third adjusting plate 565. A first groove 527 is provided on the side of the limiting seat 526 away from the third adjusting plate 565. A second groove 525 is provided on the inner wall of the first groove 527. The inner wall diameter of the second groove 525 is larger than the inner wall diameter of the first groove 527. A first electromagnet 521 is fixedly disposed on the inner wall of a second groove 525, and a second electromagnet 522 is sleeved on the inner wall of the second groove 525.

[0033] Deflection component 52 also includes: The limiting rod 523 is fixedly installed on the side of the second electromagnet 522 away from the first electromagnet 521 and extends to the outside of the limiting seat 526. The end of the limiting rod 523 away from the second electromagnet 522 is hinged to the side of the adjusting frame 561 near the electric push rod 564. The second pressure sensor 524 is sleeved on the side wall of the limiting rod 523 and is located on the side of the second electromagnet 522 away from the first electromagnet 521. The side wall of the limiting rod 523 located in the second groove 525 is sleeved with a second spring, and the second spring is located on the side of the second pressure sensor 524 away from the second electromagnet 522.

[0034] In practical implementation, by energizing the first electromagnet 521 and the second electromagnet 522, a repulsive force is generated on the side where the first electromagnet 521 and the second electromagnet 522 are close to each other. This repulsive force drives the second electromagnet 522 and the limiting rod 523 to move. Since the limiting rod 523 is hinged to the adjusting frame 561, and deflection components 52 are provided on both sides of the adjusting frame 561, and since the first adjusting plate 566 and the second adjusting plate 563 are rotatably connected to the top center and bottom center of the adjusting frame 561, respectively, the difference in repulsive force between the first electromagnet 521 and the second electromagnet 522 of the two deflection components 52 allows the adjusting frame 561 to be deflected when different forces are applied to both sides of the adjusting frame 561, thus tilting the adjusting frame 561. Multiple extrusion blocks 552 are pressed, thereby causing extrusion blocks 552 and extrusion cylinders 557 at different positions to move by different distances. This allows the extrusion cylinders 557 at different positions to apply different extrusion forces to different positions of the edge banding strip. During the edge banding process of the edge banding strip and furniture board 3, the extrusion force on the edge banding strip is gradually increased, thereby improving the edge banding effect. It also facilitates the simultaneous adjustment of the positions of multiple extrusion cylinders 557, making it convenient for practical operation. During the adjustment process, when the second electromagnet 522 drives the limit rod 523 to move, the second spring presses the second pressure sensor 524, thereby determining the force of the second electromagnet 522 pressing the second spring. This allows for the control of the force applied by the two deflection components 52 to both sides of the adjustment frame 561, facilitating practical adjustment.

[0035] By designing the extrusion block 552 in an arc shape, the adjusting frame 561 can contact the extrusion block 552 when the adjusting frame 561 extrudes the extrusion block 552 at different angles, thereby facilitating the synchronous movement of multiple extrusion blocks 552 and improving the stability of the extrusion cylinder 557.

[0036] Please see Figure 10 and Figure 12 The monitoring component 53 includes: The second fixing plate 534 is fixedly installed on the top of the mounting plate 51. The side wall of the second fixing plate 534 is fitted with a connecting rod 531. One end of the connecting rod 531 is fixedly connected to the side of the extrusion block 552 away from the frame 558. A retaining ring 533 is fixedly sleeved on the other side wall of the connecting rod 531. A first pressure sensor 532 is fixedly mounted on the side of the second fixing plate 534 near the retaining ring 533. A first spring is sleeved on the side wall of the connecting rod 531 located between the first pressure sensor 532 and the retaining ring 533.

[0037] In practical implementation, when the adjusting frame 561 drives the extrusion block 552 and extrusion cylinder 557 to extrude the edge banding strip, the extrusion block 552 drives the connecting rod 531 and the retaining ring 533 to move along the side wall of the second fixed plate 534, thereby causing the retaining ring 533 to extrude the first spring. The extrusion of the first spring acts on the first pressure sensor 532, thereby monitoring the extrusion force of the extrusion block 552 and extrusion cylinder 557 on the edge banding strip through the first pressure sensor 532. According to the monitored force, the repulsive force difference between the first electromagnet 521 and the second electromagnet 522 of the two deflection components 52 is adjusted, thereby driving the extrusion block 552 and extrusion cylinder 557 at different positions to move different distances, so that the extrusion cylinder 557 at different positions applies different extrusion forces to different positions of the edge banding strip. If the monitored force is large, the extrusion force is reduced accordingly; if the monitored force is small, the extrusion force is increased accordingly. This allows the position and angle of the adjusting frame 561 to be adjusted according to the actual situation, thereby adjusting the extrusion force of the extrusion cylinder 557 on the edge banding strip. It also facilitates monitoring of the pressure exerted by a single extrusion cylinder 557 on the sealing strip, allowing for adjustments based on the actual sealing situation. Furthermore, it applies pressure from the center of the extrusion block 552 to the drive retaining ring 533 on the first pressure sensor 532, improving the accuracy of pressure monitoring.

[0038] The adjustment frame 561 moves and deflects on the side wall of the connecting rod 531, so as not to affect the rotation and movement of the adjustment frame 561, which is convenient for actual adjustment and use.

[0039] There is space between the extrusion block 552 and the second fixed plate 534 for the adjustment frame 561 to move and deflect. The second adjustment plate 563 is U-shaped so as to be staggered with the first fixed plate 551. The side of the adjusting frame 561 away from the electric push rod 564 can contact the side wall of the extrusion block 552, and the limiting rod 523 extends along the inner wall of the first groove 527 to the outside of the limiting seat 526.

[0040] Example 2, please refer to Figure 11 The difference between this embodiment and Embodiment 1 lies in the fact that the cooling component 54 includes: Fluid slip rings 542 are fixedly disposed on the opposite side of the connecting plate 553 and are coaxially designed with the rotating rod 559. The opposite ends of the two fluid slip rings 542 are respectively fixed with a first conduit 541 and a second conduit 544. The opposite ends of the two fluid slip rings 542 are respectively fixed with a third conduit 543 and a fourth conduit 546. The third conduit 543 is connected to the first conduit 541 through one of the fluid slip rings 542, and the fourth conduit 546 is connected to the second conduit 544 through the other fluid slip ring 542. The guide groove 545 is located inside the extrusion cylinder 557 and has an annular design. The third guide tube 543 and the fourth guide tube 546 extend to the upper end and lower end of the inner wall of the guide groove 545, respectively, and are located on both sides of the rotating rod 559.

[0041] In practical implementation, coolant is connected to the first conduit 541 and the second conduit 544 via external pipes, allowing coolant to enter the guide groove 545 along the first conduit 541 and the third conduit 543. This allows the extrusion cylinder 557 to contact the edge sealing strip during extrusion, thereby cooling the edge sealing strip. By having multiple extrusion cylinders 557 contact the edge sealing strip sequentially, coolant at different temperatures is delivered within the multiple extrusion cylinders 557, thus providing gradient cooling to the functional layer within the edge sealing strip and improving the cooling effect.

[0042] Because the guide channel 545 is annular, the coolant flows through the second conduit 544 and is connected to an external pipe, allowing the coolant to flow through the guide channel 545 and be discharged along the fourth conduit 546 and the second conduit 544. This allows the coolant to circulate within the guide channel 545, improving the cooling effect. The fluid slip ring 542 is designed to cool the functional layer inside the sealing strip while allowing the extrusion cylinder 557 to rotate, thus not affecting the connection between the first conduit 541 and the conduit. The design of the second slider and the second slide groove 555 facilitates the synchronous movement of the fluid slip ring 542 with the extrusion cylinder 557 without affecting the installation of the fluid slip ring 542, thus not affecting the connection between the first conduit 541 and the second conduit 544.

[0043] By supplying coolant into the extrusion cylinder 557, and the outer ring of the extrusion cylinder 557 is usually made of rubber to reduce damage to the edge sealing strip during extrusion, the pressure of the coolant in the guide channel 545 is controlled to control the rigidity of the extrusion cylinder 557. This allows the extrusion cylinder 557 to stably extrude the edge sealing strip while facilitating the adjustment of the contact area between the extrusion cylinder 557 and the edge sealing strip according to the actual situation, thus facilitating actual cooling.

[0044] Please see Figure 16 A control system for a formaldehyde-free edge banding device for furniture boards is provided. The control system includes a data acquisition module, a processing module, a control module, and a display module. The output of the data acquisition module is connected to the input of the processing module, and the output of the processing module is connected to the inputs of the control module and the display module.

[0045] In practical implementation, the force exerted by the extrusion cylinder 557 on the edge sealing strip and the force exerted by the extrusion adjustment frame 561 are collected by the acquisition module, such as the first pressure sensor 532 and the second pressure sensor 524. The collected information is then transmitted to the processing module for processing. After receiving the data collected by the first pressure sensor 532 and the second pressure sensor 524, the processing module performs conventional signal conditioning, analog-to-digital conversion, filtering and noise reduction on the data in sequence. The processed data is then transmitted from the output end to the display module and the control module, respectively. The display module displays the data so that the staff can understand the pressure value. After receiving the processed data collected by the first pressure sensor 532, the control module performs a threshold judgment. If the judgment is greater than the set upper threshold, the control module outputs a corresponding control command to reduce the extrusion force of the extrusion cylinder 557 on the edge sealing strip. If the judgment is less than the set lower threshold, the control module outputs a corresponding control command to increase the extrusion force of the extrusion cylinder 557 on the edge sealing strip. After receiving the processed data collected by the second pressure sensor 524, the control module performs a threshold judgment. If the judgment is greater than the set upper threshold, it outputs a corresponding control command to reduce the squeezing force of the extrusion cylinder 557 on the adjustment frame 561; if the judgment is less than the set lower threshold, it outputs a corresponding control command to increase the squeezing force of the extrusion cylinder 557 on the adjustment frame 561. Specifically, the control module outputs corresponding control commands to adjust the parameters of the electric push rod 564, the first electromagnet 521, and the second electromagnet 522, causing the adjustment frame 561 to deflect and move accordingly for adjustment, thereby facilitating actual adjustment and improving edge sealing efficiency.
