Technical Field
[0001] This utility model belongs to the field of vulcanizing tank technology, and specifically relates to a sealing device for a rubber vulcanizing tank. Background Technology
[0002] A rubber vulcanizing tank is a device used for vulcanizing rubber products. It is a closed tank made of low-carbon steel plate. Electric vulcanizing tanks directly heat the medium inside the tank (such as air or water) through electric heating tubes or plates, generating a high-temperature, high-pressure environment that causes the rubber molecules to undergo a cross-linking reaction, thereby improving the strength, elasticity, and aging resistance of the product. According to their structure, they can be divided into single-wall vulcanizing tanks and double-wall vulcanizing tanks. Single-wall vulcanizing tanks use saturated steam or hot compressed air for vulcanization. When using compressed air, a heater must be installed inside the tank. Double-wall vulcanizing tanks only use heated air for vulcanization, with steam introduced between the inner and outer walls. There are also vertical and horizontal vulcanizing tanks, but most are single-wall horizontal vulcanizing tanks.
[0003] A traction trolley is a commonly used track-mounted trolley in a vulcanizing tank. It is used to push the trolley loaded with semi-finished products into the vulcanizing tank, and then pull the trolley out after vulcanization. Opening a vulcanizing tank while it is pressurized or before the internal pressure has been fully released is extremely dangerous. Safety devices must be installed to ensure safety. However, traditional vulcanizing tanks require manual removal of a pin to open the lid, which poses a safety hazard under high temperature and pressure conditions. Manual operation under high pressure and high temperature is inherently dangerous. Utility Model Content
[0004] The purpose of this utility model is to provide a sealing device for a rubber vulcanizing tank to solve the problems mentioned in the background art. To achieve the above objective, this utility model provides the following technical solution: it includes a tank body and a heating module and a pressure system disposed on the tank body. Openings are provided on both sides of the tank body, and a cover is provided at each opening. A mechanical arm is fixedly connected to the tank body, and the end of the mechanical arm is rotatably connected to the cover. A power device for rotating the cover is provided on the mechanical arm, and a sealing structure is provided between the cover and the tank body.
[0005] The sealing structure is a high-temperature resistant sealing ring disposed between the tank body and the cover body. The side of the tank body facing the cover body is provided with an installation ring. The installation ring is provided with an installation groove for installing the high-temperature resistant sealing ring. The inner wall of the installation ring is provided with a plurality of axially equidistant positioning blocks. The positioning blocks are located on the side away from the tank body. A gap is reserved between the positioning blocks and the high-temperature resistant sealing ring to accommodate the insertion of a locking block. The side of the cover body facing the tank body is provided with a plurality of axially equidistant protrusions. The protrusions are located between two positioning blocks. One of the protrusions has a locking block on the side facing the positioning block. The locking block inserts between the positioning block and the high-temperature resistant sealing ring.
[0006] It should be noted in the solution that an inner liner is fixedly installed inside the tank, and the inner liner has several equidistantly distributed air outlets. A guide rail is also fixed inside the inner liner.
[0007] It should be noted in the solution that the inner ring of the high-temperature resistant sealing ring is provided with an annular stop.
[0008] It should be noted in the design that a circulating fan is provided in the middle part of the inner liner.
[0009] It should be noted in the solution that the side of the card block facing the cover is sloping.
[0010] Compared with the prior art, the rubber vulcanizing tank sealing device provided by this utility model has at least the following beneficial effects:
[0011] (1) By setting up a robotic arm and a sealing structure, in actual use, after the rubber products are loaded into the can, the robotic arm is started so that the robotic arm covers the opening of the can. Then the motor is started to rotate the cover. The locking block on the cover passes between the positioning block and the high-temperature resistant sealing ring. The cover and the locking block are completely fixed together. The locking block and the protrusion squeeze the high-temperature resistant sealing ring to achieve a better sealing effect. After the vulcanization is completed, the motor is started to rotate the cover so that the locking block is separated from the positioning block and the high-temperature resistant sealing ring. The robotic arm is started to separate the cover from the can. Both ends of the can are covers that can be opened and closed by the robotic arm, which can optimize the feeding and discharging process.
[0012] (2) By setting the inner liner, in actual use, the electric heating tube or electric heating plate in the electric heating system is installed in the inner liner and the tank is heated through the air outlet on the inner liner. The rubber that needs to be vulcanized is placed on the guide rail by the transport vehicle to prevent it from bumping into the heating device during transportation. The inner liner and the guide rail mainly play the role of protection and fixation. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figure 1-5 A sealing device for a rubber vulcanizing tank includes a tank body 1 and a heating module and a pressure system disposed on the tank body 1;
[0021] In the prior art, tank 1 is a high-pressure resistant steel tank with a horizontal design. The inner wall may be coated with a high-temperature resistant anti-corrosion coating. The electric heating system is equipped with electric heating tubes or electric heating plates installed in the tank jacket or inside. It directly heats the air inside the tank through resistance heating. It is also equipped with a temperature control system, a PID temperature controller: to accurately adjust the heating power, and the temperature difference can be controlled within ±1℃. Some equipment is equipped with multi-zone temperature monitoring, with multiple thermocouples monitoring the temperature of different areas inside the tank in real time to ensure uniformity. The pressure system relies on external compressed air or nitrogen for pressurization and is controlled independently of the heating system.
[0022] However, to ensure safety, safety devices must be installed. But to open the can, the latch must be manually pulled out before the lid can be turned open. Manual operation under high pressure and high temperature poses a significant risk.
[0023] Furthermore, referring to Figure 1-5 As shown, it is worth noting that both sides of the tank body 1 are provided with openings, and a cover 2 is provided at the opening of the tank body 1. A mechanical arm 3 is also fixedly connected to the tank body 1. The end of the mechanical arm 3 is rotatably connected to the cover 2. A power device for rotating the cover 2 is provided on the mechanical arm 3. A sealing structure is also provided between the cover 2 and the tank body 1.
[0024] The sealing structure is provided with a high-temperature resistant sealing ring 9 between the tank body 1 and the cover body 2. The side of the tank body 1 facing the cover body 2 is provided with an installation ring 14. The installation ring 14 is provided with an installation groove for installing the high-temperature resistant sealing ring 9. The inner wall of the installation ring 14 is provided with a plurality of axially equidistant positioning blocks 7. The positioning blocks 7 are located on the side away from the tank body 1. A gap is reserved between the positioning blocks 7 and the high-temperature resistant sealing ring 9 to accommodate the insertion of a locking block 11. The side of the cover body 2 facing the tank body 1 is provided with a plurality of axially equidistant protrusions 10. The protrusions 10 are located between two positioning blocks 7. One of the protrusions 10 is provided with a locking block 11 on the side facing the positioning block 7. The locking block 11 is inserted between the positioning block 7 and the high-temperature resistant sealing ring 9. The power device includes a motor 4 mounted on a robotic arm 3. The output end of the motor 4 is inserted into the robotic arm 3 and fixedly connected to the cover body 2.
[0025] With the robotic arm 3 and the sealing structure, in actual use, after the rubber product is loaded into the can, the robotic arm 3 is activated, so that the robotic arm 3 covers the opening of the can 1 with the cover 2. Then, the motor 4 is activated to rotate the cover 2. The locking block 11 on the cover 2 passes between the positioning block 7 and the high-temperature resistant sealing ring 9, and the cover 2 and the locking block 11 are completely fixed together. The locking block 11 and the protrusion 10 squeeze the high-temperature resistant sealing ring 9 to achieve a better sealing effect. After vulcanization is completed, the motor 4 is activated to rotate the cover 2, so that the locking block 11 is disengaged from the positioning block 7 and the high-temperature resistant sealing ring 9. The robotic arm 3 is activated to separate the cover 2 from the can 1. Both ends of the can 1 are covered by the cover 2 that can be opened and closed by the robotic arm 3, which can optimize the feeding and discharging process.
[0026] Furthermore, referring to Figure 1-5 As shown, it is worth noting that an inner liner 6 is fixedly installed inside the tank 1, and the inner liner 6 is provided with a number of equidistantly distributed air outlets 12. A guide rail 13 is also fixed inside the inner liner 6.
[0027] With the inner liner 6 in place, the heating element or heating plate of the electric heating system is installed inside the inner liner 6 during actual use. The air outlet 12 on the inner liner 6 heats the inside of the tank 1. The rubber that needs to be vulcanized is placed on the guide rail 13 by the transport vehicle to prevent it from bumping into the heating device during transportation. The inner liner 6 and the guide rail 13 mainly serve to protect and fix the device.
[0028] Furthermore, referring to Figure 1-5 As shown, it is worth noting that a circulating fan is provided in the middle part of the inner liner 6;
[0029] By setting up a circulating fan, the gas inside the tank 1 can be circulated more quickly, making the temperature inside the tank 1 more uniform and reducing the temperature difference between different areas inside the tank 1, thereby further improving the vulcanization quality of the rubber.
[0030] Furthermore, referring to Figure 1-5 As shown, it is worth noting that the inner ring of the high-temperature resistant sealing ring 9 is provided with an annular stop block;
[0031] By setting the high-temperature resistant sealing ring 9, in actual use, when the cover 2 and the tank 1 are closed, the high-temperature resistant sealing ring 9 is squeezed by the protrusion 10 on the cover 2 and the tank 1, which reduces the gap between the tank 1 and the cover 2 and achieves the sealing effect. Setting an annular block in the inner ring of the high-temperature resistant sealing ring 9 can further enhance the sealing effect.
[0032] Furthermore, referring to Figure 1-5 As shown, it is worth noting that the side of the card block 11 facing the cover 2 is inclined.
[0033] With the setting of the locking block 11, when the cover 2 and the tank 1 are closed, the cover 2 is rotated so that the locking block 11 is inserted between the positioning block 7 and the high temperature resistant sealing ring 9. One side of the locking block 11 is inclined so that it can be inserted better between the positioning block 7 and the high temperature resistant sealing ring 9.
[0034] The above describes a sealing device for a rubber vulcanizing tank provided by this utility model. Specific preferred embodiments have been used to illustrate the principle and implementation of this utility model. These embodiments are only used to help understand the principle and core idea of this utility model. It should be noted that for those skilled in the art, the implementation schemes in the above embodiments can be further combined or replaced without departing from the design concept of this utility model, and several improvements and modifications can be made to this utility model. These improvements and modifications also fall within the protection scope of the claims of this utility model.
