Description

Technical Field

[0001] This application belongs to the field of cutting tape technology, specifically a low-noise EPDM cutting tape. Background Technology

[0002] Low-noise EPDM cutting tape is made primarily of EPDM rubber. It possesses excellent flexibility and wear resistance, generates low noise during cutting, making it suitable for cutting scenarios where noise levels are critical. It ensures cutting quality and has significant application value in industrial production and other fields.

[0003] For example, CN208417405U discloses a low-noise EPDM cutting tape, which includes a tape body and a covering layer. The covering layer wraps the tape body. The tape body includes a top adhesive layer, a first buffer adhesive layer, a reinforcing layer, a second buffer adhesive layer, and a bottom adhesive layer. The top adhesive layer is fixedly connected to the first buffer adhesive layer, and the first buffer adhesive layer is fixedly connected to the reinforcing layer. A rope core is embedded in the reinforcing layer. The reinforcing layer is fixedly connected to the second buffer adhesive layer. An I-shaped block is embedded between the reinforcing layer and the second buffer adhesive layer. The second buffer adhesive layer is fixedly connected to the bottom adhesive layer. Both side walls of the bottom adhesive layer are provided with grooves, and sound-absorbing blocks are embedded in the grooves. This utility model has a simple structure. By embedding an I-shaped block between the reinforcing layer and the second buffer adhesive layer, it avoids the reinforcing layer from gradually breaking and elongating due to the mutual shearing between the fibers during operation. The sound-absorbing blocks embedded in the grooves make the tape less prone to noise generation.

[0004] However, when using the low-noise EPDM cutting tape described in this application, if the cutting tape lacks an easily disassembled structure, it is difficult to perform targeted repairs when a component inside malfunctions. Repair personnel may need to spend a significant amount of time locating and fixing the problem, and may even have to discard the entire cutting tape because they cannot repair small internal parts, thus increasing repair costs and wasting resources. Utility Model Content

[0005] The purpose of this application is to provide a low-noise EPDM cutting tape in order to solve the problems mentioned above.

[0006] The technical solution adopted in this application is as follows: a low-noise EPDM cutting tape includes a first rotor, a second rotor is provided on one side of the first rotor, a turntable is fixedly connected to one end of the second rotor relative to the first rotor, a plurality of fixing blocks are fixedly connected to one side surface of the turntable, a screw hole is provided on one side of the fixing block, a screw is provided on one side of the screw hole, and a nut is fixedly connected to one end of the screw.

[0007] By adopting the above technical solution, during use, operators can hold the nut to thread the screw through the through hole on one side of the cutting strip, and then turn it into the screw hole to assemble the cutting strip with the fixing block and turntable structure. When replacement or disassembly is required, simply turn the screw again to remove it. When a part of the cutting strip, such as the noise-reducing coating wears, the reinforcing fiber layer breaks, or the wear-resistant surface is damaged, the easy-to-disassemble structure allows maintenance personnel to quickly separate the damaged part for repair. Compared with traditional one-piece cutting strips, this structure avoids replacing the entire cutting strip due to minor damage, reducing maintenance costs and resource waste. At the end of the cutting strip's service life, the easy-to-disassemble structure makes the replacement process more efficient. Operators can complete the disassembly of the cutting strip and the installation of a new cutting strip in a short time, reducing equipment downtime and thus improving production efficiency.

[0008] In a preferred embodiment, the outer surface of the turntable is provided with a wear-resistant surface layer.

[0009] By adopting the above technical solution, the wear-resistant surface layer, as the outermost layer of the cutting strip, directly resists the cutting friction, effectively resists wear, extends the service life of the cutting strip, and ensures the continuous and stable operation of the cutting operation.

[0010] In a preferred embodiment, an EPDM rubber base layer is provided on the inner side of the wear-resistant surface layer, and a noise-reducing coating is fixedly connected to one end of the EPDM rubber base layer.

[0011] By adopting the above technical solution, the EPDM rubber main layer forms the core of the cutting strip. Its excellent elasticity and flexibility allow the cutting strip to flexibly adapt to various cutting paths, ensuring operational stability. The noise-reducing coating is made of sound-absorbing material, which efficiently absorbs and scatters sound waves during cutting, reducing noise and creating a relatively quiet and comfortable working environment for operators, thus improving their work experience.

[0012] In a preferred embodiment, an adhesive layer is provided on one side of the noise-reducing coating.

[0013] By adopting the above technical solution, the adhesive layer can strongly bond all structural components, ensuring the overall structure of the cutting strip is stable, effectively transferring stress, preventing delamination, and maintaining the stable performance of the cutting strip.

[0014] In a preferred embodiment, the adhesive layer is provided with a reinforcing fiber layer at one end relative to the noise-reducing coating.

[0015] By adopting the above technical solution, the tensile strength of the cutting strip can be improved by strengthening the fiber layer, effectively preventing breakage when cutting thick and hard materials, ensuring the smooth progress of the cutting process, and improving the reliability of the cutting strip.

[0016] In a preferred embodiment, a rotating motor is provided at one end of the first rotor relative to the second rotor.

[0017] By adopting the above technical solution, the rotating motor serves as the core power source for the cutting belt, driving the cutting belt to rotate stably. The speed can be precisely controlled to adapt to the cutting needs of different materials, thus promoting the efficient operation of automated cutting.

[0018] In a preferred embodiment, a power supply box is fixedly connected to one end of the rotating motor relative to the first rotor.

[0019] By adopting the above technical solutions, the power supply box provides suitable power to electric components such as rotating motors, has a complete power management function, ensures the safe and stable operation of equipment, and avoids power failures and waste.

[0020] In a preferred embodiment, a base is fixedly connected to the lower surface of the rotating motor.

[0021] By adopting the above technical solution, the base provides a solid supporting foundation for the cutting equipment, ensuring stable operation of the equipment, and is an important component of the overall structure.

[0022] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0023] In this application, during use, the operator can hold the nut to pass the screw through the through hole on one side of the cutting strip, and then screw it into the screw hole to assemble the cutting strip with the fixing block and turntable structure. When replacement or disassembly is required, simply screw the nut back in to remove it. When a part of the cutting strip, such as the noise-reducing coating, the reinforcing fiber layer, or the wear-resistant surface layer is damaged, the easy-to-disassemble structure allows maintenance personnel to quickly separate the damaged part for repair. Compared with traditional one-piece cutting strips, this structure avoids replacing the entire cutting strip due to minor damage, reducing maintenance costs and resource waste. At the end of the cutting strip's service life, the easy-to-disassemble structure makes the replacement process more efficient. Operators can complete the disassembly of the cutting strip and the installation of a new cutting strip in a short time, reducing equipment downtime and thus improving production efficiency.

When replacement or disassembly is required, simply screw the screw 6 again to remove it. When a part of the cutting strip, such as the noise-reducing coating, the reinforcing fiber layer, or the wear-resistant surface layer is damaged, the easy-to-disassemble structure allows maintenance personnel to quickly separate the damaged part for repair.

At the end of the cutting strip's service life, the easy-to-disassemble structure makes the replacement process more efficient. Operators can disassemble the cutting strip and install a new cutting strip in a short time, reducing equipment downtime and thus improving production efficiency.

[0033] Reference Figure 1 , Figure 4 The outer surface of the turntable 3 is provided with a wear-resistant surface layer 8. As the outermost layer of the cutting belt, the wear-resistant surface layer 8 directly resists the cutting friction, effectively resists wear, extends the service life of the cutting belt, and ensures the continuous and stable operation of the cutting operation.

The rotary motor 13 serves as the core power source for the cutting belt, driving the cutting belt to rotate stably. The speed can be precisely controlled to adapt to the cutting needs of different materials, thus promoting the efficient operation of automated cutting.
