Problems solved by technology

[0002] In the process of producing modified plastics, sometimes there will be broken strips. There is no obvious sign before the broken strips, and there is no obvious sound, light and other phenomena after the broken strips, so it is not easy to find, especially during night shifts. The light is not good, the mental state of the workers is poor, and this phenomenon is more frequent, resulting in large pieces of machine head material, resulting in material loss. Therefore, a new solution is urgently needed to solve this technical problem

Embodiment Construction

[0007] The technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the embodiments.

[0008] Such as figure 1 As shown, a broken bar alarm device is composed of an infrared generating device 1, an infrared receiving device 2, a photoelectric conversion device 3, and an alarm circuit 4. The infrared generating device 1 is connected to the infrared receiving device 2, and through the photoelectric conversion device 3 is connected to the alarm circuit 4, and the infrared emitting device is arranged under the extruder 6, and the extruder 6 is connected to the water tank 7 through the plastic strip 5. Before stable production, cut off the power supply of the alarm circuit, and the alarm circuit will not generate sound and light alarm signals. After stable production, turn on the power of the alarm device. At this time, the infrared generating de...

Abstract

The invention mainly relates to a broken-bar alarm device. The alarm device is mainly used for timely warning when a broken bar is generated in the process of producing modified plastic so that production personnel can discover in time, and losses caused by the broken bar are reduced. The broken-bar alarm device is formed by an infrared ray generation device, an infrared ray receiving device, a photoelectric conversion device and an alarm circuit. By using the broken-bar alarm device, in the process of producing the modified plastic, when a plastic bar is broken, sound and light alarm signalscan be emitted so that production personnel can timely take measures and the losses are reduced.

Description

technical field [0001] The invention mainly relates to a broken bar alarm device, which belongs to the technical field of alarm structural components. Background technique [0002] In the process of producing modified plastics, sometimes there will be broken strips. There is no obvious sign before the broken strips, and there is no obvious sound, light and other phenomena after the broken strips, so it is not easy to find, especially during night shifts. The light is not good, the mental state of the workers is poor, and this phenomenon is more frequent, resulting in large pieces of machine head material, resulting in material loss. Therefore, a new solution is urgently needed to solve this technical problem. Contents of the invention [0003] The object of the present invention is to provide an alarm device for broken bars, which is mainly used for timely alarming when broken bars occur during the production of modified plastics, so that production personnel can find out ...
