Description

Technical Field

[0001] This utility model relates to the technical field of aircraft tire production, and in particular to a rubber blank calendering and punching equipment. Background Technology

[0002] In the production process of aircraft tires, the calendered rubber needs to be punched. This is usually done by a new type of rubber product punching tool disclosed in utility model patent CN205799744U and a rubber outsole blank punching mechanism disclosed in utility model patent CN204172115U.

[0003] However, during use, it was found that the existing punching equipment has a relatively simple structure, and the temperature of the calendered rubber blank is high, which makes it easy for the blade to stick during punching. Furthermore, it is inconvenient to clean the punching blade, resulting in poor practicality. Therefore, there is an urgent need for a rubber blank calendering and punching equipment to improve the above problems. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a rubber blank calendering and punching equipment that conveys calendered rubber to a punching mechanism, punches the rubber, separates the punched rubber from the punching mechanism by a separation mechanism, and cleans the punching mechanism by a cleaning mechanism after the equipment has been used for a long time, thereby improving the practicality of the equipment.

[0005] This utility model discloses a rubber blank calendering and punching equipment, including a punching mechanism; it also includes a separation mechanism and a cleaning mechanism, both of which are installed on the punching mechanism;

[0006] The punching mechanism punches the rubber, the separation mechanism separates the rubber from the punching mechanism, and the cleaning mechanism cleans the punching mechanism.

[0007] The calendered rubber is fed to the punching mechanism, where it is punched. The punched rubber is then separated from the punching mechanism by a separation mechanism. After prolonged use, the punching mechanism is cleaned by a cleaning mechanism, thereby improving the equipment's usability.

[0008] Preferably, the punching mechanism includes a worktable, a top plate, a hydraulic cylinder, a lifting platform, a cutting blade, a bottom mold, and a guiding mechanism. The guiding mechanism and the bottom mold are both mounted on the worktable, the top plate and the lifting platform are both mounted on the guiding mechanism, the hydraulic cylinder is mounted on the top plate, the cleaning mechanism is mounted on the lifting platform, and the cutting blade is mounted on the separating mechanism. The calendered rubber is conveyed to the bottom mold, and through the extension of the hydraulic cylinder and the guidance mechanism, the lifting platform moves downward, and the cutting blade punches the rubber.

[0009] Preferably, the guiding mechanism includes a guide column and a spring. The guide column is installed on the worktable, the top plate is installed on the top of the guide column, and the spring is fitted onto the guide column. The guide column guides the lifting platform, ensuring the stability of the lifting platform's lifting and lowering. Furthermore, when the lifting platform rises, the elasticity of the spring reduces the load on the hydraulic cylinder.

[0010] Preferably, the separation mechanism includes an air reservoir, a piston, a connecting rod, a first check valve, a second check valve, a connecting pipe, and a nozzle. The air reservoir is installed at the bottom of the top plate, the connecting rod is installed on the lifting platform, the piston is slidably installed in the air reservoir, and the top of the connecting rod is connected to the bottom of the piston. Both the first and second check valves are installed on the top of the piston, and the nozzle is installed at the bottom of the lifting platform. The second check valve is connected to the nozzle through the connecting pipe. When the lifting platform descends, the connecting rod pulls the piston downward, and at the same time, the first check valve opens, allowing air to enter the air reservoir. When the lifting platform rises, the connecting rod pushes the piston upward, and at the same time, the second check valve opens, guiding the air through the connecting pipe so that the nozzle sprays air into the cutting blade, separating the cut rubber from the cutting blade.

[0011] Preferably, the cleaning mechanism includes a hydraulic cylinder, a bracket, a fixed frame, multiple sets of springs, and multiple sets of scrapers. The bracket is mounted on the lifting platform via the hydraulic cylinder, and the cutting blade is slidably mounted on the lifting platform. The top of the cutting blade is fixedly connected to the bottom of the bracket. The fixed frame is mounted on the bottom of the lifting platform, and the multiple sets of scrapers are respectively mounted on the fixed frame via multiple sets of springs. By extending the hydraulic cylinder, the cutting blade rises, and the elasticity of the springs causes the scrapers to rub against the inner wall of the cutting blade, cleaning the rubber adhering to the inner wall of the cutting blade.

[0012] Preferably, an exhaust fan is provided on the top plate; the exhaust fan exhausts air upwards, which reduces the impact of rubber odor on surrounding workers.

[0013] Preferably, the outer ring of the piston is provided with a sealing ring to improve the piston's exhaust effect.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: the calendered rubber is conveyed to the punching mechanism, the rubber is punched by the punching mechanism, and the punched rubber is separated from the punching mechanism by the separation mechanism. Furthermore, after the equipment has been used for a long time, the punching mechanism is cleaned by the cleaning mechanism, thereby improving the practicality of the equipment.

The cutting blade 5 cuts the rubber. When the lifting platform 4 rises, the elasticity of the spring 8 reduces the load on the hydraulic cylinder 3. When the lifting platform 4 descends, the connecting rod 11 pulls the piston 10 downwards, and simultaneously, the one-way valve 12 opens, allowing air to enter the air reservoir 9. When the lifting platform 4 rises, the connecting rod 11 pushes the piston 10 upwards, and simultaneously, the one-way valve 13 opens, guiding the air through the connecting pipe 14. The nozzle 15 sprays air into the cutting blade 5, separating the cut rubber from the cutting blade 5, thus improving the equipment's practicality.
