Description

Technical Field

[0001] This utility model relates to the field of tire manufacturing technology, specifically to a safety film release agent impregnation device. Background Technology

[0002] In the tire production process, after the rubber sheets are extruded from the open mill or twin-screw extruder of the auxiliary machine, they need to be cooled by a rubber sheet cooler. Before cooling by the rubber sheet cooler, the rubber sheets need to be immersed in an isolation tank to be coated with a release agent to prevent the rubber sheets from sticking together during cooling and stacking.

[0003] When the film is immersed in the isolation tank for release agent coating, it usually needs to be manually handed or guided. However, there is a risk of entanglement during the operation of the conveyor belt and rollers in the film cooling isolation tank. The current safety devices are mainly safety ropes and photoelectric devices. However, in actual use, it has been found that once an entanglement hazard occurs, the safety ropes cannot stop the equipment in time to avoid injury to personnel, which poses a significant safety hazard. On the other hand, the photoelectric device is greatly affected by flue gas and water vapor during use, and is prone to accidental shutdown under the influence of flue gas and water vapor, which affects the normal operation of the equipment and the continuity of the production process. Therefore, there is a need for a device that can stop the machine in time to ensure personnel safety and has high stability and reliability. Summary of the Invention

The photoelectric switch is installed on the mounting rod and cooperates with the safety rod.

[0006] Furthermore, three guide rollers are arranged in an inverted triangular shape inside the isolation pool, and a V-shaped modular chain conveyor belt is wound around the three guide rollers. A drive motor is provided on one side of the isolation pool, and the output end of the drive motor is connected to one of the two guide rollers located above.

[0007] Furthermore, an upper pressure roller is provided above the V-shaped modular chain conveyor belt.

A safety rod 63 is connected between the ends of the two swing arms 62. A mounting rod 66 is connected to one of the fixed brackets 61. A photoelectric switch 64 is installed on the mounting rod 66. The photoelectric switch 64 cooperates with the safety rod 63.

[0017] Three guide rollers 7 are arranged in an inverted triangular pattern inside the isolation pool 1. A V-shaped modular chain conveyor belt 8 is wound around the three guide rollers 7. A drive motor is installed on one side of the isolation pool 1. The output end of the drive motor is connected to one of the two guide rollers 7 located above. An upper pressure roller 9 is installed above the V-shaped modular chain conveyor belt 8. The upper pressure roller 9 is installed on the side wall of the isolation pool 1 through a mounting base 10. The mounting base 10 is provided with a waist-shaped hole 11. The two ends of the central shaft of the upper pressure roller 9 are slidably installed in the waist-shaped hole 11. The waist-shaped hole 11 allows the upper pressure roller 9 to move up and down. The conveying mechanism 2 includes an inclined support 21 and a feeding conveyor belt 22. Conveying rollers 23 are respectively installed at both ends of the support 21, and the feeding conveyor belt 22 is wound around the two conveying rollers 23. A second drive motor 24 is installed at the top of the cooling mechanism 3, and the output end of the second drive motor 24 is connected to the upper conveying rollers 23. Two upper pressure guide rollers 25 and an upper pressure conveyor belt 26 are installed above the feeding conveyor belt 22. The upper pressure guide rollers 25 are mounted on the support 21, and the upper pressure conveyor belt 26 is wound around the two upper pressure guide rollers 25. A sprocket is respectively installed on the central shaft of one of the conveying rollers 23 and one of the upper pressure guide rollers 25, and the two sprockets are connected by a chain. During film conveying, the film is clamped between the feeding conveyor belt 22 and the upper pressure conveyor belt 26 for transport. The feeding conveyor belt 22 can also be a modular chain, facilitating the flow of the release agent through the gaps in the modular chain. Below the conveying mechanism 2 and the cooling mechanism 3, there is a liquid collection tank 12, and the lower end of the liquid collection tank 12 is connected to the isolation pool 1; the cooling mechanism 3 adopts a cooling air chamber, and a hanging rod that can rotate in a circulating manner is installed in the cooling air chamber. After the film is conveyed by the conveying mechanism, it falls to and is suspended on the hanging rod for cooling. The process of using this utility model: An input belt is installed at the front of the isolation tank 1 to feed the film onto the V-shaped modular chain conveyor belt 8 in the isolation tank 1. The film is immersed in the release agent in the isolation tank 1 on the V-shaped modular chain conveyor belt 8. The central shaft of the upper pressure roller 9 is installed in the waist-shaped hole 11 on the mounting base 10. The waist-shaped hole 11 allows the upper pressure roller 9 to move up and down. Under the action of gravity, the upper pressure roller 9 presses on the V-shaped modular chain conveyor belt 8 to tension the V-shaped modular chain conveyor belt 8. The film is then fed from the V-shaped modular chain conveyor belt 8 to the conveying mechanism 2. The conveyor belt 22 transports the film, and the upper pressure conveyor belt 26 presses on top of the film. The film passes between the feeding conveyor belt 22 and the upper pressure conveyor belt 26. After being conveyed by the conveying mechanism 2 to the cooling mechanism 3, the film falls into the cooling mechanism 3. The cooling mechanism 3 adopts a cooling air chamber, in which a circulating rotating hanging rod is installed. The film is suspended on the hanging rod for cooling. During the process of the film passing through the conveying mechanism 2 and the cooling mechanism 3, the release agent on the film falls into the collection tank 12 and flows back into the isolation pool 1 along the collection tank 12. When staff perform operations such as transferring sheets through the operating window 5, there is a risk of falling into the isolation pool 1 or getting caught in the V-shaped modular chain conveyor belt 8. The safety protection device 6 is installed inside the operating window 5 of the protective shell 4 above the isolation pool 1. The safety bar 63 is installed between the swing arms 62, which can swing around the rotating shaft 65. Under normal working conditions, the safety bar 63 hangs down naturally, and the photoelectric switch 64 senses the obstruction of the safety bar 63, allowing the isolation pool 1 to operate normally. In the event of a fall, if any part of the staff touches the safety bar 63, causing the position of the safety bar 63 to shift, the photoelectric switch 64 will not sense the presence of the safety bar 63 and will immediately stop the isolation pool 1 through the operating system and issue an alarm, effectively ensuring the personal safety of the staff.
