Description

Technical Field

[0001] This application relates to the field of board coating technology, and in particular to an energy-saving wood veneer surface treatment coating device. Background Technology

[0002] Energy-saving wood veneer panels are a new type of decorative board made primarily of wood substrate, relying on environmentally friendly manufacturing processes and energy-saving structural molding. They combine excellent decorative effects, practical performance, and low-carbon environmental advantages. A coating device is needed to perform surface coating processing on the panels, which can form a dense protective film on the panel surface, effectively improving the wear resistance and stain resistance of the panels and extending their service life. This is a core process for optimizing the overall quality of the panels. Therefore, it is urgent to develop an energy-saving wood veneer panel surface treatment coating device to ensure the quality of panel coating processing and meet the high-quality production requirements of wood veneer panels.

[0003] The existing technology still has the following problems:

[0004] 1. Existing lamination equipment is unable to completely remove dust, debris, and particles from the surface of the board. This results in dust particles being trapped between the substrate and the film layer, forming obvious bumps, bubbles, pits, and particle marks, which damage the surface flatness and decorative aesthetics, resulting in defective products. Furthermore, dust can hinder the effective adhesion between the film and the substrate, causing insufficient local adhesion and making problems such as film peeling, delamination, and edge curling easy to occur, which seriously reduces the durability of the board. In addition, hard particles can scratch the substrate and film surface, forming irreversible indentations, leading to product scrap.

[0005] 2. Existing laminating equipment lacks a stress buffer mechanism when the film is discharged. The film material is transported in a rigid and unbuffered direct traction state, which easily leads to uneven stress on the film layer and violent tension fluctuations. This causes the film material to be overstretched, deformed, or shifted during discharge, resulting in wrinkles, ripples, and stretch marks on the surface after lamination, affecting the flatness and aesthetics of the decoration. In addition, the film is prone to shifting during the traction process, resulting in inaccurate lamination alignment, missed edges of the boards, and single-sided lamination that is too wide or too narrow, causing a large number of boards to become substandard products. Summary of the Invention

[0006] To overcome the shortcomings of existing laminating devices that struggle to thoroughly remove dust, debris, and particles from the surface of wood veneer panels, resulting in dust particles trapped between the substrate and the film layer, causing noticeable bumps, bubbles, pits, and particle marks, damaging surface smoothness and decorative aesthetics, and producing substandard products, and to address these issues by providing an energy-saving wood veneer panel surface treatment laminating device to solve the aforementioned deficiencies. Furthermore, dust can hinder effective adhesion between the film and the substrate, leading to insufficient local adhesion and problems such as film peeling, delamination, and edge curling, severely reducing the durability of the wood veneer. Additionally, the lack of stress buffering mechanisms during film discharge in existing laminating devices results in a rigid, unbuffered direct traction state for the film, easily causing uneven stress and severe tension fluctuations in the film layer. This can lead to excessive stretching, deformation, or displacement of the film during discharge, resulting in wrinkles, ripples, and stretch marks on the laminated surface, affecting decorative smoothness and aesthetics.

[0017] The technical solution provided in this application has at least the following technical effects or advantages:

[0018] 1. By employing a cleaning component, this invention effectively solves the problem of existing laminating devices failing to thoroughly remove dust, debris, and particles from the board surface. Dust particles trapped between the substrate and the film layer can cause noticeable bumps, bubbles, pits, and particle marks, damaging surface smoothness and aesthetic appeal, resulting in substandard products. Furthermore, dust can hinder effective adhesion between the film and substrate, leading to insufficient local adhesion and problems such as film peeling, delamination, and edge curling, severely reducing the durability of the board. In addition, hard particles can scratch the substrate and film surface, creating irreversible indentations and rendering the product unusable. This invention addresses these issues through the cleaning component... This product thoroughly cleans dust, debris, and hard particles from the surface of boards, effectively preventing appearance defects such as bumps, bubbles, pits, and particle marks after lamination. It significantly improves the flatness and decorative effect of the board surface, reduces the scrap rate due to poor appearance, eliminates the hidden danger of dust hindering adhesion, ensures a tight bond between the film and the board, enhances lamination adhesion, reduces defects such as film peeling, delamination, and edge curling during the use of finished products, and significantly extends the service life of wood veneer panels. At the same time, it avoids the problem of hard particles squeezing and scratching the board and film, causing permanent indentations, reducing the waste of board and film materials, and saving raw material costs.

[0019] 2. By employing stress-reinforcing components, this invention effectively solves the problem of existing laminating devices lacking stress buffering mechanisms during film discharge. This results in rigid, unbuffered direct traction of the film material, easily leading to uneven stress and severe tension fluctuations. This causes excessive stretching, deformation, or misalignment of the film material during discharge, resulting in wrinkles, ripples, and stretch marks on the laminated surface, affecting the smoothness and aesthetics of the finish. Furthermore, film misalignment during traction causes inaccurate lamination alignment, missing edges, and uneven or excessively wide edges, resulting in a large number of defective products. This invention effectively solves the problems of rigid traction and large tension fluctuations during film discharge through stress-reinforcing components. It ensures smoother film transport and more uniform tension, preventing excessive stretching, deformation, and misalignment. It eliminates quality defects such as wrinkles, ripples, and stretch marks on the laminated surface, significantly improving surface smoothness and aesthetics. Simultaneously, it achieves precise film alignment and transport, eliminating lamination misalignment, missing edges, and uneven edge width, ensuring product dimensional consistency and appearance qualification rate, and greatly reducing the defect rate.

[0034] For applications where it is difficult to thoroughly remove dust, debris, and particles from the surface of boards, this invention uses a cleaning component to thoroughly clean the surface of the boards, effectively preventing appearance defects such as bumps, bubbles, pits, and particle marks after lamination. This significantly improves the surface smoothness and decorative effect of the boards, and reduces the scrap rate due to poor appearance. Furthermore, for lamination devices that lack a stress buffer mechanism during film discharge, this invention uses a stress component to effectively solve the problems of rigid traction and large tension fluctuations during film discharge, making the film transport more stable and the tension more uniform, thus preventing excessive stretching, deformation, and displacement of the film.

[0035] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods. Example 1:

[0036] Please see Figure 1 and Figure 2As shown, an energy-saving wood veneer surface treatment laminating device includes a laminating machine body 1, a transmission rod 2, a heating chamber 4, a laminating roll 6, and a laminating mechanism 7. The transmission rod 2 is rotatably connected to the inner cavity of the laminating machine body 1. A motor can be installed inside the laminating machine body 1 to drive the rotation of the transmission rod 2. Heating rollers and adhesive rollers are installed on the inner wall of the heating chamber 4. The laminating mechanism 7 is installed on the inner wall of the laminating machine body 1. The laminating mechanism 7 includes two pressure rollers and a drive motor. When the workpiece 5 moves, it can pass between the two pressure rollers, allowing the drive motor to rotate the pressure rollers to perform laminating on the workpiece 5. A cleaning component 3 is installed on the outer surface of the laminating machine body 1. The outer surface of the moving rod 2 is equipped with a workpiece 5, a coated roll 6, and a coating machine body 1. The outer surface of the coating machine body 1 is equipped with a stress component 8. When the workpiece 5 is coated, the workpiece 5 is conveyed by the rotation of the transmission rod 2 within the inner cavity of the coating machine body 1. The cleaning component 3 is used to correct the position of the workpiece 5 and remove dust from its surface. The heating chamber 4 is used to preheat the workpiece 5 and apply adhesive. The stress component 8 is used to provide prestress when the coated roll 6 is discharged. Thus, the outer surface of the workpiece 5 is coated by the coating mechanism 7, making the film conveying more stable and the tension more uniform, ensuring product size consistency and appearance qualification rate, and significantly reducing the defect rate.

[0037] Please see Figure 2 and Figure 3 As shown, the cleaning component 3 includes a fixed frame 31, which is fixedly connected to the laminating machine body 1. A dust collection box 32 is fixedly installed on the upper surface of the fixed frame 31. A negative pressure fan is installed inside the dust collection box 32, and a suction pipe 33 is slidably connected to the inner cavity of the dust collection box 32. A suction head 34 is fixedly connected to the end of the suction pipe 33 away from the dust collection box 32. A cleaning mechanism 35 and a correction mechanism 36 are provided on the inner wall of the fixed frame 31. Before laminating the workpiece 5, the outer surface of the workpiece 5 needs to be cleaned. First, when the workpiece 5 moves to the fixed frame 31, the correction mechanism 36 is used. The aligning mechanism 36 can correct and position the workpiece 5. The cleaning mechanism 35 is used to brush the dust on the outer surface of the workpiece 5. The brush bristles remove the floating dust, wood chips and small hard particles attached to the board surface, achieving physical dust removal. Then, the negative pressure fan in the inner cavity of the dust collection box 32 drives the dust collection pipe 33 and the dust collection head 34 to adsorb the dust attached to the outer surface of the board, keeping the workpiece 5 clean on the outer surface of the film, improving the film bonding effect and the finished product qualification rate, while reducing the energy consumption caused by waste rework, and adapting to the film production needs of energy-saving wood veneer panels.

[0038] Please see Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, the cleaning mechanism 35 includes a cleaning frame 351. A motor 352 is mounted on the outer surface of the cleaning frame 351. A gear 353 is rotatably connected to the middle portion of the cleaning frame 351. A toothed plate 354 is slidably connected to the inner cavity of the cleaning frame 351. A moving block 355 is fixedly connected to one end of the toothed plate 354. A fixing plate 356 is fixedly installed on the outer surface of the cleaning frame 351. Protrusions 357 are evenly distributed on the outer surface of the fixing plate 356. A connecting block 358 is fixedly installed on the outer surface of the toothed plate 354. A first fixing block 359 is fixedly installed in the inner cavity of the connecting block 358. A sliding rod 3510 is slidably connected to the inner cavity of the first fixing block 359. A first spring 3511 is sleeved on the outer surface of the sliding rod 3510. The inner cavity of the connecting block 358 is slidably connected to... A slide 3512 is attached, and a cleaning brush 3513 is fixedly connected to the outer surface of the slide 3512. A connecting rod 3514 is fixedly installed at one end of the slide 3512, and a pressure roller 3515 is rotatably connected to the end of the connecting rod 3514 away from the slide 3512. The upper surface of the cleaning frame 351 is fixedly connected to the inner wall of the fixed frame 31. The output end of the motor 352 is sleeved with a gear 353. Half of the gear 353 is hollowed out, and the gear 353 meshes with a toothed plate 354. A moving block 355 is slidably connected to the cleaning frame 351, and the moving block 355 is fixedly connected to the junction of the suction pipe 33 and the suction head 34. The two ends of the protrusion 357 are inclined and flush with the outer surface of the fixed plate 356. There are three connecting blocks 358 on the cleaning frame 351. 512 and slide bar 3510 are fixedly connected. The first spring 3511 is located between the first fixed block 359 and slide 3512. When the toothed plate 354 moves, the pressure wheel 3515 and the protrusion 357 contact and squeeze the pressure wheel 3515. The bottom end of the cleaning brush 3513 is provided with bristles. When the workpiece 5 moves, the bristles of the cleaning brush 3513 contact the outer surface of the workpiece 5. The bristles are made of soft material to ensure that the normal movement of the workpiece 5 is not hindered when cleaning it. When cleaning the workpiece 5, the operation of the motor 352 drives the gear 353 to rotate. The rotation of the gear 353 drives the toothed plate 354 to reciprocate in the inner cavity of the cleaning frame 351. The reciprocating movement of the toothed plate 354 drives the connecting block 358 to move. The reciprocating motion of the connecting block 358 causes the slide 3512 and cleaning brush 3513 to clean the outer surface of the workpiece 5. Simultaneously, the movement of the slide 3512 moves the connecting rod 3514 and pressure roller 3515. At this time, the pressure roller 3515 and the protrusion 357 on the fixed plate 356 exert pressure, causing the slide 3512 to slide within the inner cavity of the connecting block 358. Meanwhile, the slide rod 3510 slides within the inner cavity of the first fixed block 359 and compresses the first spring 3511. The elastic force of the first spring 3511 causes the slide 3512 to reciprocate within the inner cavity of the connecting block 358, achieving bidirectional cross-sweeping of the outer surface of the workpiece 5, fully covering the dead corners of the plate surface. Simultaneously, the movement of the toothed plate 354 drives the moving block 355 to move.The movement of the moving block 355 drives the suction head 34 to move across the outer surface of the workpiece 5, thereby comprehensively removing dust from the outer surface of the workpiece 5. This thoroughly cleans the surface of the board, removing dust, debris, and hard particles, effectively preventing defects such as bumps, bubbles, pits, and particle marks after lamination. It significantly improves the surface smoothness and decorative effect, reduces the scrap rate due to poor appearance, eliminates the risk of dust hindering adhesion, ensures a tight bond between the film and the board, enhances lamination adhesion, reduces defects such as film peeling, delamination, and edge curling during the use of the finished product, and significantly extends the service life of the wood veneer panel. Simultaneously, it avoids the problem of hard particles squeezing and scratching the board and film, causing permanent indentations, reducing waste of board and film materials, and saving raw material costs.

[0039] Please see Figure 8 and Figure 9As shown, the correction mechanism 36 includes a correction plate 361. A first threaded rod 362 is rotatably connected to the inner cavity of the correction plate 361. Adjustment plates 363 are slidably connected to both ends of the correction plate 361. A first correction frame 364 is fixedly installed at the bottom end of the adjustment plate 363, and there are two first correction frames 364 on one adjustment plate 363. A second correction frame 365 is provided at the bottom end of the adjustment plate 363. A first elastic rod 366 is slidably connected to the inner cavity of the adjustment plate 363. A second spring 367 is sleeved on the outer surface of the first elastic rod 366. The outer surfaces of the correction plate 361 and the fixing frame 31 are fixedly connected. The adjustment plate 363 and the first threaded rod 362 are connected by threads, and the threads at both ends of the first threaded rod 362 are in opposite directions. The first correction frame 364 and the second correction frame 365 are... Guide rods are rotatably connected to the outer surface of the first straightening frame 365. The second straightening frame 365 and the adjusting plate 363 are slidably connected. The first elastic rod 366 and the second straightening frame 365 are fixedly connected. The second spring 367 is located between the adjusting plate 363 and the second straightening frame 365. The moving block 355 does not contact the adjusting plate 363 when it moves. The bottom ends of the first straightening frame 364 and the second straightening frame 365 are kept flush to form an opening, and the openings are initially parallel and then increase in size. The guide rods at the parallel points are located on the same plane. The opening at the bottom end of the second straightening frame 365 is larger than the opening at the bottom end of the first straightening frame 364. In this way, when the position of the workpiece 5 is offset to a certain extent, the position can be corrected by the second straightening frame 365. During the correction process of the second straightening frame 365, due to the second straightening frame 365... The entire assembly 65 is a flexible connection, so there is still a certain degree of swaying when it enters the first straightening frame 364. Therefore, the first straightening frame 364 also has a small outward opening, and guide rods are provided at both the parallel section and the opening to guide and position the workpiece 5. When the cleaning mechanism 35 cleans, the workpiece 5 is between the two pairs of first straightening frames 364, so that the workpiece 5 maintains stable movement during the cleaning process. At the same time, the vacuum head 34 leaves the last first straightening frame 364 only after vacuuming, so that the workpiece 5 remains centered after cleaning. The spacing of the adjusting plates 363 is adjusted according to the width of the workpiece 5. By rotating the first threaded rod 362, the adjusting plates 363 slide on the outer surface of the straightening plate 361, so that the workpiece 5 passes through the first straightening frame 361. 64. The guide rods on both sides and parallel ends of the workpiece 5 are in contact with the second straightening frame 365. The second straightening frame 365 and the adjusting plate 363 are flexibly connected, which provides a buffering effect when the workpiece 5 is being corrected. When the workpiece 5 deviates and comes into contact with the guide rod at the bottom of the second straightening frame 365, it will squeeze the guide rod at the opening, causing the second straightening frame 365 to slide on the outer surface of the adjusting plate 363. At this time, the first elastic rod 366 slides in the inner cavity of the adjusting plate 363 and squeezes the second spring 367. The elastic force of the second spring 367 causes the second straightening frame 365 to quickly return to its original position, correcting the position of the workpiece 5, thereby reducing the damage to the workpiece 5 when it comes into contact with the guide rod on the second straightening frame 365.This system achieves positional correction of workpiece 5. When workpiece 5 passes the first correction frame 364, it can be positioned to ensure stability during subsequent cleaning until workpiece 5 leaves the area of ​​the cleaning component 3 for the next process. Example 2:

[0040] Please see Figure 2 and Figure 10 As shown, the stress assembly 8 includes a connecting frame 81, with a second threaded rod 82 rotatably connected to the inner cavity of the connecting frame 81. Positioning mechanisms 83 are slidably connected to the outer surfaces of both ends of the connecting frame 81. Stress mechanisms 84 are provided at both ends of the connecting frame 81, with stress rods 85 rotatably connected to the inner cavity of the stress mechanisms 84. The stress mechanisms 84 are fixedly connected to the outer surface of the laminating machine body 1. When the laminating roll 6 is discharged, the spacing of the positioning mechanisms 83 is adjusted according to the width of the film. By rotating the second threaded rod 82, the positioning mechanisms 83 move on the connecting frame 81. The positioning mechanisms 83 correct and position the film discharge position, ensuring that the film and the processed part 5 remain flush during lamination. The stress rods 85 provide stress when the film is discharged, and the stress mechanisms 84 buffer stress to prevent excessive stretching and deformation of the film. At the same time, an alarm is triggered when a large tension is generated, reminding the staff to perform maintenance in time.

[0041] Please see Figure 10 and Figure 11As shown, the positioning mechanism 83 includes an adjusting block 831. A second fixing block 832 is fixedly installed on the outer surface of the adjusting block 831. A second elastic rod 833 is slidably connected to the inner cavity of the second fixing block 832. A third spring 834 is fixedly installed on the outer surface of the second elastic rod 833. A buffer block 835 is fixedly installed at one end of the second elastic rod 833, and the buffer block 835 and the adjusting block 831 are slidably connected. A first positioning rod 836 is rotatably connected to the inner cavity of the bottom end of the buffer block 835. A positioning block 837 is fixedly installed on the outer surface of 31. A second positioning rod 838 is rotatably connected to the inner cavity of the bottom end of the positioning block 837. A second elastic rod 833 and a connecting frame 81 are slidably connected. The second elastic rod 833 and a second threaded rod 82 are connected by threads, and the threads at both ends of the second threaded rod 82 are in opposite directions. A third spring 834 is located between the second fixed block 832 and the buffer block 835. When the end of the second elastic rod 833 away from the buffer block 835 is tightly fitted with the second fixed block 832, the third spring 834 is positioned between the second fixed block 832 and the buffer block 835. A positioning rod 836 and a second positioning rod 838 are located on the same plane. The position of the adjusting block 831 is adjusted by rotating the second threaded rod 82 so that when the coated roll 6 is discharged, both sides are in contact with the first positioning rod 836 and the second positioning rod 838. The first positioning rod 836 is used to flexibly limit the discharge of the coated roll 6, and the second positioning rod 838 is used to position the discharge of the coated roll 6. When the coated roll 6 deviates during discharge, the film will squeeze the first positioning rod 836, causing the buffer block 835 to slide on the outer surface of the adjusting block 831. The sliding of the adjusting block 831 drives the second elastic rod 833 to slide in the inner cavity of the second fixed block 832 and squeeze the third spring 834. The elastic force of the third spring 834 causes the buffer block 835 to return to its original position, thereby timely correcting the position of the film. The flexible correction prevents damage to the film, so that when the film passes the positioning block 837, the second positioning rod 838 can position the film, which is convenient for subsequent precise coating.

[0042] Please see Figure 10 , Figure 12 and Figure 13As shown, the stress mechanism 84 includes a stress frame 841, a stress block 842 slidably connected to the inner cavity of the stress frame 841, a fixing rod 843 fixedly installed on the inner wall of the stress frame 841, a fourth spring 844 sleeved on the outer surface of the fixing rod 843, an inclined block 845 fixedly installed on the inner wall of the stress frame 841, an alarm block 846 fixedly installed on the outer surface of the stress block 842, a pressing rod 847 slidably connected to the inner cavity of the alarm block 846, a ball bearing 848 movably connected to one end of the pressing rod 847, an alarm 849 fixedly installed on the outer surface of the alarm block 846, a connecting ring 8410 fixedly installed on the outer surface of the pressing rod 847, a fifth spring 8411 sleeved on the outer surface of the pressing rod 847, and a button 8412 provided on the inner wall of the alarm block 846. The stress frame 841 and the connecting frame 81 are fixedly connected; the stress block 842 and the fixing rod 843 are slidably connected; the fourth spring 844 is located between the stress block 842 and the inner wall of the stress frame 841; the stress rod 85 and the stress block 842 are rotatably connected; the ball 848 and the inner wall of the stress frame 841 are in close contact; the alarm 849 and the button 8412 are electrically connected, and pressing the button 8412 controls the alarm 849 to sound an alarm; the fifth spring 8411 is located between the connecting ring 8410 and the inner wall of the alarm block 846; the connecting ring 8410 and the alarm block 846 are slidably connected; when the ball 848 and the outer surface of the inclined block 845 are in contact, the pressing rod 847 compresses the button 8412; when the stress rod 85 provides stress, the stress block 842 can maintain the fourth spring 844. Spring 844 generates a certain degree of compression, which keeps the film taut and prevents it from loosening. When the coated roll 6 exits, the positioning mechanism 83 corrects and positions the exit point. Then, the positioned film is wound onto the stress rod 85 to provide stress. At this time, the processing part 5 and the film are conveyed synchronously and at a uniform speed. The pressure roller on the coating mechanism 7 rotates synchronously against the surface of the board. Through pressure and running speed, uniform and continuous vertical pressure is applied to the film, which promotes the adhesive layer of the film to fully adhere to the surface of the board, ensuring a tight and smooth adhesion between the film and the board. When the tension on the film is too great, the stress mechanism 84 can buffer the pressure. At this time, the stress rod 85 drives the stress block 842 to slide within the cavity of the stress frame 841. This causes the stress block 842 to slide on the fixed rod 843 and compress the fourth spring 844, effectively solving the problems of rigid traction and large tension fluctuations in film output. This makes the film material conveying more stable and the tension more uniform. Combined with the correction of the positioning mechanism 83, it can avoid excessive stretching, deformation and displacement of the film material, eliminating quality defects such as wrinkles, ripples and stretch marks on the laminated surface, significantly improving surface flatness and decorative aesthetics. At the same time, it can achieve precise film alignment and conveying, eliminating phenomena such as lamination offset, edge omission, and uneven lamination width, ensuring product size consistency and appearance qualification rate, and greatly reducing the defect rate. When a large tensile force is generated, the ball 848 and the inclined block 845 contact and compress the ball 848. At this time, the compression rod 847 slides in the inner cavity of the alarm block 846.This causes the connecting ring 8410 to slide within the cavity of the alarm block 846, compressing the fifth spring 8411. The movement of the compression rod 847 compresses the button 8412, causing the alarm 849 to sound, facilitating timely maintenance by staff.

[0043] In summary, when laminating workpiece 5, the transmission rod 2 rotates within the inner cavity of the laminating machine body 1 to convey workpiece 5. The cleaning component 3 is used for position correction and surface dust removal of workpiece 5. The heating chamber 4 is used for preheating and applying adhesive to workpiece 5. The stress component 8 is used to provide prestress when the laminating roll 6 is discharged. Thus, the laminating mechanism 7 performs lamination treatment on the outer surface of workpiece 5, making the film conveying more stable and the tension more uniform, ensuring product size consistency and appearance qualification rate, and significantly reducing the defect rate. Before laminating workpiece 5, the outer surface of workpiece 5 needs to be cleaned. First, when workpiece 5 moves to the fixed frame 31, the correction mechanism 36 can correct and position workpiece 5. The cleaning mechanism 35 is used to brush the dust on the outer surface of workpiece 5, relying on the brush bristles to sweep... The brushing action removes floating dust, wood chips, and small hard particles adhering to the board surface, achieving physical dust removal. Then, the negative pressure fan inside the dust collection box 32 drives the dust collection pipe 33 and dust collection head 34 to adsorb the dust adhering to the outer surface of the board, keeping the processed part 5 clean on the outer surface of the film. When the film roll 6 is discharged, the spacing of the positioning mechanism 83 is adjusted according to the width of the film. By rotating the second threaded rod 82, the positioning mechanism 83 moves on the connecting frame 81. The positioning mechanism 83 corrects and positions the film discharge position, ensuring that the film and the processed part 5 are flush during film coating. The stress rod 85 provides stress during film discharge, and the stress mechanism 84 is used for stress buffering to prevent excessive stretching and deformation of the film. At the same time, it can issue an alarm when a large tension is generated, reminding the staff to perform maintenance in time.
