Description

Technical Field

[0001] This utility model relates to the field of rubber belt production technology, specifically to a pressure roller mechanism with extrusion hot knife. Background Technology

[0002] In the rubber belt manufacturing industry, after the rubber coating process at the molding station is completed, the rubber material usually needs to be cut. Currently, this operation mainly relies on manual labor, which is inefficient and inconvenient. Furthermore, due to the special properties of rubber, traditional cold-cutting methods often fail to achieve ideal cutting results, easily leading to tearing or uneven cuts. In addition, manual operation may increase safety risks due to human error, especially during equipment operation, where operators' hands are susceptible to accidental injury.

[0003] To improve production efficiency and safety, existing technologies have attempted to introduce automated cutting devices into the pressure roller mechanism of molding machines. However, these devices often fail to fully consider the characteristics of rubber materials, and the cutter design lacks specificity, resulting in less than ideal cutting effects. Furthermore, while some devices employ heated cutters, the lack of effective protective measures in practical applications means the exposed hot blade may pose a safety hazard. In addition, existing devices are structurally complex, have high maintenance costs, and lack sensitive safety response mechanisms in the event of emergencies, further limiting their practical application effectiveness.

[0004] Therefore, designing a pressure roller mechanism that can automatically cut rubber materials, adapt to the properties of rubber, and ensure operational safety while improving production efficiency has become an urgent technical problem to be solved. This invention aims to optimize the cutting effect and improve overall safety by integrating an extrusion-type hot knife with a protective device, providing a more efficient and reliable solution for the rubber belt manufacturing industry. Utility Model Content

[0005] This invention addresses the inefficiency and operational safety issues inherent in the manual cutting of rubber material after the rubber coating process in existing rubber belt manufacturing industries. It provides an integrated extrusion hot knife and pressure roller mechanism. By combining the functions of the cutter and the pressure roller, this mechanism achieves efficient, safe, and automated rubber material cutting, while simultaneously improving the operational stability and reliability of the equipment.

[0006] This utility model provides an integrated extrusion hot knife pressure roller mechanism, including a lifting base, a mounting base, pressure roller components, a protective cover, a knife holder lifting cylinder, a heated cutter, and safety protection components. The lifting base supports the entire mechanism and provides a mounting foundation for the knife holder lifting cylinder. The mounting base is fixed to the lifting base and connects and positions the pressure roller components and other related parts. The pressure roller components are located below the mounting base and apply pressure to the rubber material to complete preliminary shaping. The protective cover is located outside the heated cutter and covers and protects the cutter when not in operation. The knife holder lifting cylinder is fixed to the lifting base, and its output end is connected to the knife holder to control the lifting action of the knife holder. The heated cutter is installed at the lower part of the knife holder and is used for high-temperature cutting of the rubber material. The safety protection components include a safety contact switch and a related linkage structure for detecting obstacles and triggering an emergency response.

[0007] Furthermore, the pressure roller and the heated cutter are integrated, and their coordinated operation is achieved through a blade holder lifting cylinder. Specifically, when the blade holder lifting cylinder drives the blade holder to descend, the heated cutter moves synchronously downward with the blade holder, and during the movement, it pushes open the protective cover, allowing the blade to contact the mold and apply pressure to the rubber material. During this process, the heated cutter utilizes its built-in temperature detection device to form a closed-loop control system with the heating element, monitoring and adjusting the working temperature of the blade in real time to meet the cutting requirements of the rubber material. When the blade holder rises, the protective cover, under the action of a spring, moves along the track mechanism plate through the protective cover opening and closing guide wheel, causing the protective cover to automatically close and completely hide the heated cutter inside the protective cover.

[0008] Specifically, the safety protection components also include a safety contact switch for the pressure roller mechanism, which is located around the pressure roller to detect the presence of obstacles. When the safety contact switch detects an obstruction, a trigger signal is transmitted to the pressure roller lifting mechanism, causing the pressure roller to immediately stop descending and automatically rise, preventing damage to operators or equipment. Furthermore, the opening and closing of the protective cover is achieved by the cooperation of the cover opening and closing guide wheels and the track mechanism plate, ensuring smooth operation of the protective cover during the lifting and lowering of the tool holder, thereby further enhancing the safety of the equipment.

[0009] Furthermore, the tool holder lifting mechanism achieves the lifting movement of the tool holder through the cooperation of a sliding seat and a guide rail. The sliding seat is fixed to the tool holder, while the guide rail is installed on the lifting base. The precise fit between the two ensures that the tool holder moves smoothly during lifting, avoiding deviation or swaying. This structural design not only improves the accuracy of the heated cutter in cutting rubber materials but also enhances the overall operational stability of the equipment.

[0010] The working principle of this utility model is as follows: S1, when it is necessary to cut the rubber material, the blade holder lifting cylinder drives the blade holder to descend, and the heated cutter moves down synchronously with the blade holder, while squeezing open the protective cover. The blade contacts the mold and applies pressure to the rubber material, and the cutting operation is completed by utilizing the high temperature characteristics of the heated cutter; S2, after the cutting is completed, the blade holder lifting cylinder drives the blade holder to rise, and the protective cover moves along the track mechanism plate through the protective cover opening and closing guide wheel under the action of the spring, automatically closing and hiding the heated cutter inside the protective cover to ensure the safety of the equipment; S3, during the operation of the pressure roller mechanism, if the safety contact switch detects an obstacle, the pressure roller lifting mechanism immediately rises automatically to prevent injury to the operator or equipment.

[0011] The beneficial effects of this invention are as follows: By integrating the extrusion hot knife with the pressure roller mechanism, the additional steps required for operating the cutter separately are reduced, significantly improving the automation and efficiency of rubber material cutting in the rubber belt production process. Simultaneously, the safety protection mechanism, through the dual protection measures of a safety contact switch and a protective cover, effectively reduces operational risks and ensures the safety of operators. Furthermore, the constant temperature control function of the heated cutter is achieved through a closed-loop system, ensuring that the blade is always in a suitable working state, thereby improving cutting accuracy and reliability. The overall structural design is reasonable, the connection relationships between various components are clear, and the interactions are well-defined, providing a more efficient and safer technical solution for the rubber belt manufacturing industry.

[0019] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0020] This utility model provides an integrated extrusion hot knife pressure roller mechanism, the specific implementation of which is described in detail with reference to the accompanying drawings. Figure 1 To be continued Figure 4 The structural diagram and the markings of each component clearly demonstrate the overall structure of the mechanism, the connection relationships between the components, and the operating principle.

[0021] like Figure 1 As shown, the core components of the entire mechanism include a lifting base 1, a mounting base 2, a pressure roller 3, a protective cover 4, a safety contact switch 5, a knife holder lifting cylinder 6, a heated cutter 7, a spring 8, a protective cover opening and closing guide wheel 9, a heating tube 10, a PT100 temperature sensing element 11, a blade 12, a sliding seat 13, and a guide rail 14. These components together constitute an automated device integrating pressure roller and cutting functions. The lifting base 1 serves as the basic support for the entire mechanism, providing a stable mounting platform for other components. The mounting base 2 is fixed to the lifting base 1 and is used to connect the pressure roller 3 and other related components. The pressure roller 3 is located below the mounting base 2, and its main function is to apply pressure to the rubber material and complete the initial molding. The protective cover 4 is located outside the heated cutter 7, covering and protecting the cutter when not in operation to ensure the safety of the operator.

[0022] In practical applications, the blade holder lifting cylinder 6 is fixed on the lifting base 1, and its output end is connected to the blade holder to control its lifting and lowering motion. The heated cutter 7 is installed at the bottom of the blade holder for high-temperature cutting of the rubber material. The heated cutter 7 has a built-in heating tube 10 and a PT100 temperature sensing element 11, achieving constant temperature regulation through a closed-loop control system. This design ensures that the blade 12 maintains a suitable working state throughout the cutting process, thereby improving cutting efficiency and accuracy. When the blade holder lifting cylinder 6 drives the blade holder to descend, the heated cutter 7 moves synchronously downwards with the blade holder, and during this movement, it pushes open the protective cover 4, allowing the blade 12 to contact the mold and apply pressure to the rubber material. During this process, the heated cutter 7 utilizes its high-temperature characteristics to quickly cut the rubber material, completing the cutting operation.

[0023] When the cutter head rises, the protective cover 4, under the action of the spring 8, moves along the track mechanism plate via the cover opening and closing guide wheel 9, automatically closing and completely concealing the heated cutter 7 within the protective cover 4. This design not only improves the safety of the equipment but also avoids accidental injury that might occur if the heated cutter 7 is exposed. The design of the cover opening and closing guide wheel 9 ensures that the protective cover 4 operates smoothly during the lifting and lowering of the cutter head, reducing friction and wear and extending the service life of the equipment. In addition, the cooperation between the sliding seat 13 and the guide rail 14 further enhances the stability of the cutter head lifting and lowering process. The sliding seat 13 is fixed on the cutter head, while the guide rail 14 is installed on the lifting base 1. The precise cooperation between the two ensures that the cutter head moves smoothly during the lifting and lowering process, avoiding deviation or shaking. This structural design significantly improves the accuracy of the heated cutter 7 in cutting rubber materials and enhances the overall operational reliability of the equipment.

[0024] To further enhance safety, this device is also equipped with a safety edge switch 5. The safety edge switch 5 is located around the pressure roller 3 and is used to detect the presence of obstacles. When the safety edge switch 5 detects an obstruction, it triggers a signal to the pressure roller lifting mechanism, causing the pressure roller 3 to immediately stop descending and automatically rise, preventing damage to operators or equipment. This dual protection mechanism effectively reduces operational risks and ensures operator safety. Simultaneously, the opening and closing of the protective cover 4 is achieved through the cooperation of the cover opening and closing guide wheel 9 and the track mechanism plate, ensuring the smooth operation of the protective cover 4 during the lifting and lowering of the tool holder, thereby further enhancing the safety of the equipment.

[0025] Combination Figure 2 and Figure 3 As can be seen, the lifting mechanism of the cutter holder achieves its lifting movement through the precise cooperation between the sliding seat 13 and the guide rail 14. The sliding seat 13 is fixed to the cutter holder, and the guide rail 14 is mounted on the lifting base 1. The cooperation between the two ensures that the cutter holder moves smoothly during the lifting process, avoiding deviation or shaking. This design not only improves the cutting accuracy of the heated cutter 7 but also enhances the overall operational stability of the equipment. Simultaneously, the constant temperature control function of the heated cutter 7 is achieved through a closed-loop system, ensuring that the blade 12 is always in a suitable working state, thereby improving cutting accuracy and reliability.

[0026] like Figure 4As shown, the output end of the blade holder lifting cylinder 6 is connected to the blade holder, controlling its lifting and lowering motion. The heated cutter 7 is installed at the bottom of the blade holder, and its blade 12 contacts the mold and applies pressure to the rubber material during the blade holder's descent. The heated cutter 7 has a built-in heating tube 10 and a PT100 temperature sensing element 11, achieving constant temperature regulation through a closed-loop control system. This design ensures that the blade 12 maintains a suitable working state throughout the cutting process, thereby improving cutting efficiency and accuracy. When the blade holder rises, the protective cover 4, under the action of the spring 8, moves along the track mechanism plate via the cover opening and closing guide wheel 9, automatically closing and completely concealing the heated cutter 7 within the protective cover 4. This design not only enhances the safety of the equipment but also avoids potential accidental injury caused by the heated cutter 7 being exposed.

[0027] In actual operation, when the rubber material needs to be cut, the blade holder lifting cylinder 6 drives the blade holder to descend, and the heated cutter 7 moves down synchronously with the blade holder, simultaneously squeezing open the protective cover 4. The blade 12 contacts the mold and applies pressure to the rubber material, utilizing the high temperature of the heated cutter 7 to complete the cutting operation. After cutting, the blade holder lifting cylinder 6 drives the blade holder to rise, and the protective cover, under the action of the spring 8, moves along the track mechanism plate via the protective cover opening and closing guide wheel 9, automatically closing and hiding the heated cutter 7 inside the protective cover, ensuring the safety of the equipment. During the operation of the pressure roller mechanism, if the safety contact switch 5 detects an obstacle, the pressure roller lifting mechanism immediately and automatically rises to prevent injury to operators or equipment. This design significantly improves the automation and efficiency of rubber material cutting in the rubber belt production process, while reducing operational risks and ensuring the safety of operators.

[0028] Overall, this invention integrates the extrusion hot knife with the pressure roller mechanism, reducing the additional steps required for operating the cutter separately and significantly improving the automation and efficiency of rubber material cutting in rubber belt production. Simultaneously, the safety protection mechanism, through the dual protection measures of the safety contact switch 5 and the protective cover 4, effectively reduces operational risks and ensures operator safety. Furthermore, the constant temperature control function of the heated cutter 7 is achieved through a closed-loop system, ensuring that the blade 12 is always in a suitable working state, thereby improving cutting accuracy and reliability. The overall structural design is reasonable, the connection relationships between components are clear, and the interactions are well-defined, providing a more efficient and safer technical solution for the rubber belt manufacturing industry.
