Description

Technical Field

[0001] This invention relates to the field of die-cutting equipment technology, and more specifically to an auxiliary noise reduction device for taking roll film materials. Background Technology

[0002] In industries such as die-cutting, lamination, electronics manufacturing, and packaging, adhesive film materials are typically stored and used in roll form. During the dispensing process, these roll films usually require continuous unwinding from the reel and peeling off from the next layer of film or release layer to achieve quantitative dispensing.

[0003] However, in existing technologies, during the unwinding or peeling process of roll-to-roll adhesive films, due to the inherent adhesiveness of the film itself, there is a significant adhesive force between it and adjacent film layers or release layers. This can easily lead to noticeable vibrations and air disturbances at the moment of peeling, resulting in substantial tearing noise or sharp sounds. This noise problem is particularly pronounced in high-speed unwinding, continuous material handling, or automated production scenarios.

[0004] The aforementioned noise not only affects the work comfort of operators, but long-term exposure to high-noise environments may also have adverse effects on hearing health. At the same time, in production workshops with high requirements for cleanliness and quiet environment (such as the fields of electronic components, precision die-cutting or medical material processing), excessive material handling noise is also difficult to meet the production environment requirements.

[0005] Currently, existing technologies for addressing noise issues during the handling of roll adhesive films mainly focus on reducing unwinding speed and changing the film material formulation. However, these methods either sacrifice production efficiency or are limited by material costs and applicability, and it is difficult to achieve stable and effective noise reduction during the handling of roll adhesive films of different specifications and viscosity grades.

[0006] Therefore, there is an urgent need to provide an auxiliary noise reduction device that is structurally sound, highly applicable, and capable of effectively suppressing the noise generated during the handling of roll film without significantly affecting the material handling efficiency, so as to solve the problem of high noise during the handling of roll film in the existing technology. Summary of the Invention

[0007] Based on the above description, the present invention provides an auxiliary noise reduction device for the extraction of roll film, so as to solve the problem of high noise in the extraction of roll film in the prior art.

[0008] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: An auxiliary noise reduction device for roll film material handling includes a hollow box with an opening on one side. A door for closing the opening of the box is hinged to the opening. A horizontally arranged support tube for the roll film core tube to be sleeved on the inner wall of the box directly opposite the opening is fixedly connected. A fixed limiting plate for abutting against the roll film is fixedly connected to the support tube. A disassembly limiting plate for abutting against the other side of the roll film roller is detachably connected to the support tube. An auxiliary noise reduction structure is provided on the inner wall of the box, which can slide horizontally and applies a constant force to the roll film to be peeled to maintain the peeling angle of the roll film to be peeled at less than 20°. A discharge groove for the roll film to pass through is provided on the side wall of the box.

[0009] Through the above technical solution, during the roll film extraction process, the film needs to be peeled off from adjacent film layers. The peeling angle directly affects the stress state and energy release mode during peeling. When the peeling angle is large, the peeling force is concentrated on the adhesion interface between the film and the adjacent film layers, causing the film to break rapidly in a short time. This results in significant elastic rebound and high-frequency vibration of the film, accompanied by instantaneous air disturbance, thus generating considerable noise. Conversely, when the peeling angle is small, the peeling force is gradually released along the adhesion interface, and the film peels off from the adjacent film layers in a gradual manner. The breakage process at the adhesion interface is smoother, and the vibration amplitude and air disturbance intensity of the film are significantly reduced, thereby effectively reducing the noise generated during peeling. This invention can stably maintain the film at a small peeling angle through its structure. Therefore, by reasonably guiding and limiting the peeling angle during the roll film extraction process, the film can maintain a small and stable peeling angle, effectively suppressing the film peeling noise without significantly affecting the extraction efficiency.

[0010] Based on the above technical solution, the present invention can be further improved as follows.

[0011] Furthermore, the auxiliary noise reduction structure includes a deformation clamping roller arranged parallel to the support tube and whose central axis is coplanar with the central axes of the support tube and the film core tube. The plane containing the central axes of the deformation clamping roller, the support tube, and the film core tube is parallel to the horizontal plane. A counterweight steel block suspended inside the box is connected to the deformation clamping roller.

[0012] Furthermore, the auxiliary noise reduction structure also includes a sliding support frame rotatably connected to the deformation clamping roller. A T-shaped guide rail block is fixedly connected to the top of the sliding support frame. A guide rail groove for the T-shaped guide rail block to pass through and slide is fixedly connected to the inner top wall of the box. A flexible steel cable for fixed connection with the counterweight steel block is fixedly connected to the sliding support frame. A horizontally arranged connecting rod is fixedly connected to the inner wall of the box. A guide ring for the flexible steel cable to pass through is fixedly connected to the connecting rod.

[0013] Furthermore, a vertically arranged guide rod is fixedly connected to the bottom of the counterweight steel block, and a guide tube for the guide rod to pass through and slide is fixedly connected to the inner bottom surface of the box. Furthermore, the deformation clamping roller includes a rotating spindle rotatably connected to the sliding support frame. A rigid inner tube is sleeved on the outer side of the rotating spindle, an elastic tube is fixedly connected to the outer side of the rigid inner tube, and a rigid outer tube is fixedly connected to the outer side of the elastic tube. Furthermore, an air supply rigid tube is rotatably connected to the sliding support frame located below the deformation clamping roller. The air supply rigid tube is horizontally arranged and parallel to the deformation clamping roller. An air outlet groove with the same length direction as the air supply rigid tube is connected to the air supply rigid tube. The opening of the air outlet groove can move with the rotation of the air supply rigid tube to the position to be lifted facing the rolled film. An air supply pipe extending out of the box is connected to the air supply rigid tube.

[0014] Furthermore, a locking threaded rod that is rotatably connected to the sliding support frame is fixedly connected to one side of the rigid air supply pipe along its length. A locking nut is threaded onto the locking threaded rod, and symmetrically arranged auxiliary force rods are fixedly connected to the locking nut. Furthermore, both the fixed limiting plate and the disassembly limiting plate are provided with clearance grooves for the deformation clamping roller to abut against the rolled film. A sleeve tube fitted onto the outside of the support pipe is fixedly connected to the disassembly limiting plate. A snap-fit ​​screw is threaded onto the sleeve tube, and a force-applying knob is fixedly connected to the top of the snap-fit ​​screw. A snap-fit ​​hole is provided on the support pipe for the bottom of the snap-fit ​​screw to pass through.

[0015] Furthermore, sound-absorbing cotton layers are fixedly connected to the inner walls of the enclosure and the inner sides of the door, and the sound-absorbing cotton layers are provided with clearance sections for the rubber membrane to pass through. Furthermore, magnetic rubber rings that can attract each other are fixedly connected to the joints of the enclosure and the door. Insertion blocks that overlap when the door is closed are fixedly connected to the enclosure and the door respectively. Insertion holes that gradually become coaxial as they overlap are opened on the insertion blocks, and insertion rods are inserted into the insertion holes. Several circumferentially distributed connecting plates are fixedly connected to the enclosure on the side opposite to the opening. The support tube is a tube that is closed on one side, with the closed side located inside the enclosure. An elastic rubber layer is fixedly connected to the inner wall of the support tube.

[0016] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0017] 1. This invention applies a stable and continuous force to the area of ​​the film to be peeled during the roll film picking process, guiding and limiting the peeling angle of the film. This ensures that the film maintains a small and stable peeling angle throughout the picking process, making the peeling process between the film and adjacent film layers smoother. This effectively reduces the elastic rebound, high-frequency vibration and air disturbance intensity generated at the moment of peeling, and significantly reduces the noise generated during the roll film picking process.

[0018] 2. By setting an auxiliary noise reduction structure that can slide horizontally, the position of the adhesive film to be peeled can be adaptively adjusted according to the change of the diameter of the rolled adhesive film, thereby maintaining a stable peeling state throughout the process of gradually unwinding the roll material, and avoiding the problem of sudden noise increase caused by the peeling angle fluctuation due to the change of roll diameter.

[0019] 3. By adopting a pressure roller structure with deformation capability, it can generate a buffering and vibration absorption effect when in contact with the adhesive film. While ensuring the effective guiding force applied to the adhesive film, it further reduces the vibration amplitude of the adhesive film during the peeling process, and reduces the additional noise caused by the rigid contact of the structure and the damage to the surface of the adhesive film.

[0020] 4. By combining the counterweight with the guide structure, the force applied by the auxiliary noise reduction structure to the area where the film is to be lifted is made more stable, avoiding additional noise caused by force fluctuations or component swings, thereby improving the stability and consistency of the noise reduction effect.

[0021] 5. By setting an adjustable air supply structure, the airflow can be directed to the area where the adhesive film is to be peeled off, which helps to reduce the adhesion resistance between the adhesive film and adjacent film layers, making the peeling process smoother, further reducing the noise caused by sudden adhesion changes during the peeling process, and improving the operability and adaptability of adhesive film material sourcing.

[0022] 6. By setting sound-absorbing structures inside the enclosure and on the inside of the door, and by sealing the joint between the enclosure and the door, the reflection and outward propagation of stripping noise inside the enclosure are effectively reduced, further improving the overall noise reduction effect and improving the working environment.

[0023] 7. By axially limiting both sides of the rolled film and designing vibration reduction and protection for the support structure, it is possible to effectively prevent the roll material from shifting, shaking or deviating during the material handling process, ensuring a stable and smooth film output process and reducing abnormal noise and film damage caused by roll material instability.

[0032] To facilitate understanding of this application, it will now be described more fully with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application.

[0034] An auxiliary noise reduction device for obtaining roll film materials, such as Figures 1-3As shown, the device includes a hollow box 1 with an opening on one side. Box 1 is formed by welding multiple steel plates. A door 2, made of steel, is hinged to the opening of box 1 for closing. A support tube 3, made of steel, is fixedly connected to the inner wall of box 1 directly opposite the opening, for mounting a core tube of rolled adhesive film. The support tube 3 is welded to box 1. The support tube 3 provides initial support and positioning for the adhesive film core tube, facilitating subsequent... To ensure stable access to the adhesive film, a fixed limiting plate 4 is fixedly connected to the support tube 3 to abut against the rolled adhesive film. The fixed limiting plate 4 is made of steel and is fixed to the support tube 3 by welding. A detachable limiting plate 5 is detachably connected to the support tube 3 to abut against the other side of the rolled adhesive roller. The combined action of the fixed limiting plate 4, the support tube 3, and the detachable limiting plate 5 achieves stable positioning of the rolled adhesive film, ensuring that the rolled adhesive film can be in a stable position and can be accessed stably. The inner wall of the housing 1 is provided with a horizontal sliding surface for... An auxiliary noise reduction structure applies a constant force to the area where the rolled adhesive film is to be peeled, maintaining a peel angle of less than 20°. Under the same conditions, a larger peel angle results in greater elastic energy release and air turbulence during film peeling, leading to more noise; conversely, a smaller peel angle results in less noise. Therefore, the auxiliary noise reduction structure allows the peel angle to be stably maintained at a small acute angle. This structure effectively reduces noise during the use of the adhesive film, minimizing noise generated during film handling. To mitigate the impact on the working environment and the health of employees, a discharge chute 6 is provided on the side wall of the housing 1 for the adhesive film to pass through. The discharge chute 6 allows the peeled adhesive film to be removed from inside the housing 1 and used stably thereafter. With the combined action of the housing 1, the door 2, and the discharge chute 6, it is ensured that the adhesive film can be removed and used from inside the housing 1 while preventing the noise generated during the removal process from directly spreading outside the housing 1. The obstruction and attenuation provided by the housing 1 and the door 2 further reduce the impact of noise generated during the removal process on the surrounding environment.

[0035] like Figures 1-5As shown, the auxiliary noise reduction structure includes a deformation-adhesive roller arranged parallel to the support tube 3, with its central axis coplanar with the central axes of the support tube 3 and the film core tube. The plane containing the central axes of the deformation-adhesive roller, the support tube 3, and the film core tube is parallel to the horizontal plane. A counterweight steel block 7 is connected to the deformation-adhesive roller and suspended inside the housing 1. The auxiliary noise reduction structure also includes a sliding support frame 8 rotatably connected to the deformation-adhesive roller. The sliding support frame 8 is made of steel, and a T-shaped guide rail block 9 is fixedly connected to the top of the sliding support frame 8. The T-shaped guide rail block 9 is made of steel and is fixed to the sliding support frame 8 by welding. A guide rail is fixedly connected to the inner top wall of the housing 1 for the T-shaped guide rail block 9 to pass through and slide. The guide rail 10 is made of steel and is fixed to the inner top wall of the housing 1 by welding. The guide rail 10 forms a T-shaped groove with the same shape and size as the T-shaped guide rail block 9. The guide rail 10 provides stable guidance and limit for the sliding process of the T-shaped guide rail block 9, ensuring a smoother and more stable sliding process for the T-shaped guide rail block 9, and thus ensuring a smoother and more stable sliding process for the sliding support frame 8. A flexible steel cable 11 for fixing to the counterweight steel block 7 is fixed to the sliding support frame 8 by screws or welding. The flexible steel cable 11 is fixed to the counterweight steel block 7 by welding or screws. When fixing by clamping, the user can select different types of counterweight steel blocks 7 according to their needs. This ensures that the gravity of the counterweight steel blocks 7 can drive the deformation clamping roller to stably clamp the part of the adhesive film to be lifted, making the overall structure more adaptable. The gravity of the counterweight steel blocks 7 is applied to the flexible steel cable 11 connected to them. The flexible steel cable 11 transfers the gravity of the counterweight steel blocks 7 to the sliding support frame 8. As the size of the adhesive film gradually decreases, the gravity of the counterweight steel blocks 7 will pull the sliding support frame 8 to slide. During the sliding process, the sliding support frame 8 will drive the deformation clamping roller connected to it to move. During the movement of the deformation clamping roller, it will maintain the adhesive film to be lifted. Partial clamping ensures the clamping and limiting functions of the deformation clamping roller remain stable, thereby ensuring the stable implementation of the auxiliary noise reduction function of the auxiliary noise reduction structure. A horizontally set connecting rod 12 is fixedly connected to the inner wall of the housing 1. The connecting rod 12 is made of steel and is fixed to the inner wall of the housing 1 by welding. A guide ring 13 for the flexible steel cable 11 to pass through is fixedly connected to the connecting rod 12. The guide ring 13 is made of steel and is fixed to the connecting rod 12 by welding. The guide ring 13 and the connecting rod 12 are used to achieve stable guidance and limiting of the sliding process of the flexible steel cable 11, ensuring that the sliding and driving process of the flexible steel cable 11 is more stable and smooth.

[0036] like Figures 1-7As shown, a vertically arranged guide rod 14 is fixedly connected to the bottom of the counterweight steel block 7. The guide rod 14 is made of steel and is fixed to the counterweight steel block 7 by welding. A guide tube 15 is fixedly connected to the inner bottom surface of the box body 1 for the guide rod 14 to pass through and slide. The guide tube 15 is made of steel and is fixed to the inner bottom surface of the box body 1 by welding. The deformation pressing roller includes a rotating spindle 16 rotatably connected to the sliding support frame 8. A rigid inner tube 17 is sleeved on the outside of the rotating spindle 16. An elastic tube 18 is fixedly connected to the outside of the rigid inner tube 17. The elastic tube 18 is made of rubber and is fixed to the rigid inner tube 17 by epoxy structural adhesive. The outside of the elastic tube 18 is fixed by epoxy structural adhesive. A rigid outer tube 19 is fixedly connected. The rigid outer tube 19 is made of steel and has a smooth outer surface. With the combined action of the rotating spindle 16 and the rigid inner tube 17, the rigid inner tube 17 can rotate better relative to the sliding support frame 8. The elastic deformation property of the elastic tube 18 can generate a buffering and vibration absorption effect when in contact with the adhesive film. While ensuring that an effective guiding force is applied to the adhesive film, it further reduces the vibration amplitude of the adhesive film during the peeling process, reduces the additional noise caused by the rigid contact of the structure and the damage to the surface of the adhesive film. The rigidity of the rigid outer tube 19 ensures that the external force can be applied more evenly to the elastic tube 18 and drive the elastic tube 18 to undergo elastic deformation. At the same time, it avoids the adhesive film being affected by the excessive friction coefficient of the surface of the elastic tube 18.

[0037] like Figures 1-7 As shown, a rigid air supply pipe 20 is rotatably connected to a sliding support frame 8 located below the deformation clamping roller. The rigid air supply pipe 20 and the sliding support frame 8 are rotatably connected through a shaft hole fit. The rigid air supply pipe 20 is horizontally arranged and parallel to the deformation clamping roller. An air outlet groove 21 with the same length direction as the rigid air supply pipe 20 is connected to the rigid air supply pipe 20. Both the rigid air supply pipe 20 and the air outlet groove 21 are made of steel and are fixed together by welding. The opening of the air outlet groove 21 can move with the rotation of the rigid air supply pipe 20 to the position to be lifted facing the rolled film. An air supply pipe 22 is connected to the rigid air supply pipe 20 and extends out of the housing 1. With the help of a small HAP2000 system... The hot air blower generates flowing hot air and sends it into the air supply pipe 22. Under the transport and guidance of the air supply pipe 22, the hot air is sent into the rigid air supply pipe 20. Under the guidance of the rigid air supply pipe 20, the hot air flows out from the air outlet slot 21. According to the properties of the adhesive in the film, the temperature of the output hot air is adjusted by the temperature control system of the HAP2000 series hot air blower, so that when the hot air blows to the opening, the adhesive of the film is in a state of softening but not melting. This makes the film easier to tear and use, reducing the noise caused by excessive adhesive stickiness during the opening and use of the film, and reducing the noise level generated during the use of the film.

[0038] like Figures 1-7 As shown, a locking threaded rod 23, which is rotatably connected to the sliding support frame 8, is fixedly connected to one side of the rigid air supply pipe 20 along its length by welding. The locking threaded rod 23 and the sliding support frame 8 are rotatably connected by a shaft hole. On the side of the rigid air supply pipe 20 away from the locking threaded rod 23, a smooth rod is fixedly connected to the sliding support frame 8 by welding, which is rotatably connected by a shaft hole. The rigid air supply pipe 20 achieves its rotatable connection to the sliding support frame 8 through the combined action of the locking threaded rod 23 and the smooth rod. The rotation of the rigid air supply pipe 20 adjusts the orientation of the air outlet slot 21, allowing the user to adjust the position of the air outlet slot 21 according to their needs, so that the orientation of the air outlet slot 21 and the guiding effect of hot air can better meet the user's needs. A locking nut 24 is threadedly connected to the locking threaded rod 23, and symmetrically arranged auxiliary force rods 25 are fixedly connected to the locking nut 24. Both the locking nut 24 and the auxiliary lever 25 are made of steel and fixed by welding. The auxiliary lever 25 uses the principle of lever-saving to allow the user to drive the locking nut 24 to rotate more effectively. During the rotation of the locking nut 24, it slides relative to the locking threaded rod 23. During the sliding process, the locking nut 24, together with the air supply rigid tube 20, clamps or loosens the sliding support frame 8. When the locking nut 24 is clamping the sliding support frame 8, the friction between the locking nut 24 and the sliding support frame 8 restricts the rotational freedom of the air supply rigid tube 20, ensuring that the air supply rigid tube 20 is in the desired position and orientation, making the position and effect of the air supply rigid tube 20 more stable. When the locking nut 24 is in the loosened state, the restriction on the rotational freedom of the air supply rigid tube 20 is lost, allowing the user to adjust the orientation of the air outlet groove 21 as needed.

[0039] like Figures 1-7As shown, both the fixed limiting plate 4 and the disassembly limiting plate 5 are provided with a clearance groove 26 for the deformation clamping roller to abut against the rolled film. The clearance groove 26 extends from the outer edge of the fixed limiting plate 4 or the disassembly limiting plate 5 to the inner side of the core tube of the film. The groove is provided to provide a stable clearance during the process of the deformation clamping roller abutting against the rolled film, ensuring that the deformation clamping roller can always maintain abutment against the rolled film with a gradually decreasing diameter, thereby ensuring that the auxiliary noise reduction function can be stably implemented. The disassembly limiting plate 5 has a through-hole... A sleeve 27, made of steel, is fixedly connected to the outside of the support tube 3 by welding. A snap-fit ​​screw 28 is threaded onto the sleeve 27. A threaded tube with its central axis perpendicular to the sleeve 27 is fixedly connected to the sleeve 27 by welding. The threaded tube communicates with the interior of the sleeve 27 and is threadedly connected to the snap-fit ​​screw 28. The snap-fit ​​screw 28 slides relative to the threaded tube during rotation. The top of the snap-fit ​​screw 28 is bonded with adhesive. A force-applying knob 29 is fixedly connected in a manner that utilizes the principle of a lever to allow the user to more effectively drive the locking screw 28 to rotate. This allows the locking screw 28 to slide more smoothly relative to the threaded tube and the sleeve tube 27. The support tube 3 has a locking hole 30 for the bottom of the locking screw 28 to pass through. During the sliding process, the locking screw 28 will pass through or out of the locking hole 30. When the snap-fit ​​screw 28 is inserted into the snap-fit ​​hole 30, it will stabilize and limit the relative sliding process between the sleeve tube 27 and the support tube 3, ensuring that the disassembly limiting plate 5 can be in a stable position and realize its limiting function for the roll of film, so that the roll of film can be in a stable position and can be used stably afterwards. When the snap-fit ​​screw 28 passes out of the snap-fit ​​hole 30, the limiting function of the snap-fit ​​screw 28 will be lost. At this time, the disassembly limiting plate 5 can be removed to realize the disassembly and replacement of the used film.

[0040] like Figures 1-7As shown, the inner walls of the enclosure 1 and the inner sides of the door 2 are fixedly connected with sound-absorbing cotton layers 31 by adhesive. The sound-absorbing cotton layers 31 provide stable shielding for the inner walls of the enclosure 1 and the door 2. The sound-absorbing cotton layers 31 have clearance sections for the adhesive film to pass through. These clearance sections are cut to form a through-slot connecting to the discharge chute 6. The adhesive film, using these clearance sections, can stably pass through the sound-absorbing cotton layers 31 and exit the enclosure 1 via the discharge chute 6, allowing the user to access the adhesive film. The sound-absorbing cotton layer 31 is made of polyester fiber. The good and stable sound absorption effect of this material is used to ensure that the sound-absorbing cotton layer 31 has good and stable sound absorption performance. The box 1 forms a semi-closed cavity. The peeling sound is easily reflected and amplified in the cavity. The sound-absorbing cotton layer 31 can absorb mid-to-high frequency sound energy, reduce noise reflection and leakage, reduce the reflection of the inner wall of the box 1 to avoid the formation of the sound box effect, so that the overall sound insulation effect of the structure is better, and further reduce the impact of noise generated during the process of taking out the roll of film on the surrounding environment.

[0041] like Figures 1-7As shown, the joint between the box body 1 and the box door 2 is fixedly connected with mutually attractive magnetic rubber rings 32 by adhesive. The magnetic rubber rings are made of anisotropic magnetic rubber. This material ensures that the magnetic rubber rings 32 on the box body 1 and the box door 2 can be stably attracted when they are attached to each other, achieving a stable seal at the joint between the box door 2 and the box body 1, enhancing the overall sealing performance of the structure, and reducing the degree of noise generated during the removal of adhesive film inside the box body 1 transmitted to the outside of the box body 1, thus strengthening the overall noise reduction stability of the structure. The ring width of the magnetic rubber ring 32 on the box door 2 is larger than that on the box door 2, and the magnetic rubber ring 32 on the box body 1 can be completely attached to the end face of the magnetic rubber ring 32 on the box door 2. The box body 1 and the box door 2 are respectively fixedly connected by welding with interlocking blocks 33 that overlap when the box door 2 is closed. The interlocking blocks 33 are made of steel and have openings on them that gradually overlap as they overlap. A coaxially arranged insertion hole 34 is provided, and an insertion rod 35 is inserted into the insertion hole 34. The insertion rod 35 and the insertion block 33 are interlocked to achieve stable limiting of the opening process of the box door 2, ensuring that the box door 2 can be in a stable closed state, and achieving sound insulation during the film removal process. Several circumferentially distributed connecting plates 36 are fixedly connected to the box body 1 on the side opposite to the opening. The connecting plates 36 are made of steel and are fixed to the box body 1 by welding. The connecting plates 36 are used to assist the user in installing the whole structure in the required position on the die-cutting equipment. The support tube 3 is a tube with one closed side, and its closed side is located inside the box body 1. This setting can reduce noise transmission directly to the outside of the box body 1 through the cavity of the support tube 3. An elastic rubber layer 37 is fixedly connected to the inner wall of the support tube 3. The elastic rubber layer 37 is made of butyl rubber. The good sound insulation properties of this type of material are used to enhance the sound insulation performance of the support tube 3 and the whole structure.

[0042] Working Principle: In use, the box door 2 is first opened, and the core tube of the rolled film is fitted onto the support tube 3 fixed to the inner wall of the box 1. One side of the rolled film is abutted against the fixed limiting plate 4, and the other side is limited by the disassembly limiting plate 5, thereby achieving stable positioning of the roll material inside the box 1. During the material handling process, the film is drawn out from the outer periphery of the roll material and passes through the discharge chute 6 and out of the box 1. Then, the box door 2 is closed. Under the attraction and sealing of the magnetic rubber ring 32 and the limiting cooperation of the insertion block 33 and the insertion rod 35, the box 1 forms a relatively closed soundproof cavity. The sound-absorbing cotton layer 31 on the inner wall of the box 1 and the inner side of the box door 2 absorbs the reflection and leakage of peeling sound. To reduce noise diffusion, the area of ​​the adhesive film to be peeled off comes into contact with the deformation-adhesive roller. Guided by the guide rail groove 10, the deformation-adhesive roller slides smoothly horizontally via the sliding support frame 8. Its movement is driven by the gravity of the suspended counterweight 7, which is transmitted to the sliding support frame 8 via the flexible steel cable 11. Under the limiting guidance of the guide ring 13, the force direction remains stable, allowing the sliding support frame 8 to continuously compensate for the decrease in the adhesive film roll diameter. This ensures that the deformation-adhesive roller consistently applies a relatively constant pressing and guiding action to the area of ​​the adhesive film to be peeled off, maintaining a small and stable peeling angle during the peeling process and preventing sudden peeling. The high-frequency vibration and air disturbance caused by the concentrated release of intermittent energy are thus stabilized and noise is reduced. At the same time, the deformation clamping roller is ensured to rotate smoothly with the film by rotating the spindle 16 and the rigid inner tube 17. The elastic tube 18 generates buffer and vibration absorption when under pressure to further reduce the vibration amplitude. The rigid outer tube 19 is used to uniformly transmit external force and avoid excessive friction affecting the unwinding stability. When it is necessary to further reduce adhesion resistance and peeling noise, the hot air blower can be turned on to allow hot air to enter the air supply rigid tube 20 through the air supply pipe 22, and blow it in a directional direction towards the area where the film is to be lifted by the air outlet groove 21. By adjusting the hot air temperature, the adhesive layer is made to "soften". The "non-melting" state reduces adhesion peaks and peeling impact, thereby further reducing noise. The orientation of the air outlet groove 21 can be adjusted by rotating the air supply rigid pipe 20 relative to the sliding support frame 8, and the angle is maintained by clamping the sliding support frame 8 with the locking nut 24. As the adhesive film is continuously taken out and the roll diameter gradually decreases, the automatic compensation mechanism driven by the counterweight continuously maintains the adhesion and limit between the deformation clamping roller and the outer periphery of the roll material, so that the small peeling angle and the buffering and vibration absorption effect are stable for a long time. Finally, with the cooperation of the sound insulation and sound absorption structure of the box 1, the noise during the roll material adhesive film taking process is continuously suppressed and its impact on the working environment and personnel health is reduced.
