Description

Technical Field

[0001] This utility model relates to the field of tire production equipment, and more specifically to a rubber production sheet conveying jam alarm and emergency stop device. Background Technology

[0002] As is well known, rubber sheets processed in an internal mixer need to pass through conveyor rollers or conveyor belts and be cooled in a sheet cooler to meet process requirements. Because sheet coolers contain many areas with harsh environments and poor visibility, rubber blockage can go undetected, easily leading to equipment damage, lengthy repair times, high maintenance costs, and significant difficulty for personnel to handle. Summary of the Invention

[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a rubber production sheet conveying blockage alarm and emergency stop device to eliminate the risk of equipment damage caused by rubber sheet blockage.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a rubber production film conveyor jamming alarm and emergency stop device, which is equipped with a film conveyor belt. The feature is that a transmission guide roller is installed above the film conveyor belt via a bearing, a film trigger plate is fixed on the lower side of the transmission guide roller, a feedback plate is fixed at one end of the transmission guide roller, and a proximity switch is installed at the position corresponding to the feedback plate. The proximity switch is connected to the signal input terminal of the PLC controller, and the signal output terminal of the PLC controller controls the alarm and the switch of the drive motor of the film conveyor belt.

[0005] The beneficial effects of this utility model are that it enables automatic alarm and shutdown when film gets stuck, avoiding equipment failure caused by film sticking, effectively reducing the intensity of manual operation, and significantly improving equipment operating efficiency. Attached Figure Description

[0006] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0007] Figure 1 This is a schematic diagram of the structure of the present invention.

[0008] In the diagram: 1. Film conveyor belt, 2. Bearing, 3. Drive guide roller, 4. Film trigger plate, 5. Feedback plate, 6. Proximity switch. Detailed Implementation

[0009] In the figure, the present invention includes a film conveyor belt 1, a transmission guide roller 3 is installed above the film conveyor belt 1 via a bearing 2, a film trigger plate 4 is fixed on the lower side of the transmission guide roller 3, a feedback plate 5 is fixed at one end of the transmission guide roller 3, and a proximity switch 6 is installed at the position corresponding to the feedback plate 5. The proximity switch 6 is connected to the signal input terminal of the PLC controller, and the output terminal of the PLC controller controls the alarm and the switch of the film conveyor belt drive motor.

[0010] The film trigger plate 4 is installed above the area of ​​the film conveyor belt 1 where glue is easily stuck. The lower end of the film trigger plate 4 is close to the film conveyor belt 1. Under normal working conditions, the film passes under the film trigger plate 4 through the film conveyor belt 1 without touching the film trigger plate 4. When the film gets stuck, the height of the film increases, and it will touch the film trigger plate 4. The action of the film trigger plate 4 will drive the transmission guide roller 3 and the feedback plate 5 to rotate. The proximity switch 6 senses the signal change and transmits it to the PLC controller, which transmits the stop signal to the equipment electrical control system to realize the emergency stop function of the equipment and issue an alarm signal.

Claims

1. A rubber sheet conveyor with rubber jamming alarm and emergency stop device, comprising a rubber sheet conveyor belt, characterized in that, A drive guide roller is mounted on the top of the film conveyor belt via a bearing.
