[0010] Compared with the prior art, the beneficial effects of the utility model are as follows: The pipeline plugging material alarm mechanism is reasonably designed and ingeniously conceived. By arranging an elastic pressing sheet on the inner wall of the pipeline, after the pipeline is blocked by materials, the material particles gather and accumulate upward. When reaching the position of the alarm, the material particles squeeze the pressing sheet to retract, thereby triggering the proximity switch. The proximity switch controls the alarm to give an alarm, enabling the staff to promptly discover the pipeline blockage and deal with it, avoiding equipment damage and not affecting the production rhythm.

[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments (for the convenience of description and understanding, the upper part of Figure 2 is described as the upper part). Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0017] Please refer to Figures 1-4 , the present utility model provides a technical solution: A pipeline plugging material alarm mechanism, including a pipeline 1. A limiting groove 8 is arranged at a position close to the discharge port on the inner side surface of the pipeline 1. A pressing sheet 3 is arranged in the limiting groove 8. A fixing block 5 is arranged on one side at the upper end of the limiting groove 8. One end of a spring 6 is connected to the fixing block 5, and the other end of the spring 6 is connected to the upper end of the pressing sheet 3. When the spring 6 is not stressed, the pressing sheet 3 is in an inclined state, ensuring that the material particles can better squeeze the pressing sheet 3 during accumulation, improving the retraction sensitivity of the pressing sheet 3. A proximity switch 7 is arranged on one side of the limiting groove 8. An alarm 9 is arranged on the outer side surface of the pipeline 1. The output end of the proximity switch 7 is electrically connected to the alarm 9. By the extrusion of the material particles on the pressing sheet 3 during plugging, the proximity switch 7 is triggered. The alarm 9 is triggered by the proximity switch 7 to give an alarm, thereby reminding the staff to deal with it.
[0018] Further, in order to facilitate the flexible rotation of the pressing piece 3, rotating shafts 4 are rotatably connected to both sides of the lower end of the limiting groove 8, and the rotating shafts 4 pass through the lower end of the pressing piece 3.
[0019] Further, one side of the pressing piece 3 is an arc structure, which can increase the area of the material particles squeezing the pressing piece 3 and ensure that the pressing piece 3 can retract sensitively.
[0020] Further, in order to prevent the material particles from accumulating on the upper end of the pressing piece 3 and causing difficulty in retracting the pressing piece 3, a material blocking plate 2 is arranged directly above the pressing piece 3. The material blocking plate 2 is an arc structure and is fixedly connected to the inner wall of the pipeline 1.
[0021] Further, in order to improve the support stability of the pressing piece 3, the number of the springs 6 is two, and the two springs 6 are symmetrically arranged on the plane of the limiting groove 8.
[0022] Among them, the model of the proximity switch 7 is selected as the NBB15 threaded proximity switch, and the alarm 9 can be selected for sound alarm, light alarm or a combination of both.
[0023] During use: When the pipeline 1 is blocked, the material particles gather and accumulate upwards. When reaching the position of the alarm 9, the material particles squeeze the pressing piece 3. At this time, the pressing piece 3 retracts counterclockwise. When reaching the detection range set by the proximity switch 7, the proximity switch 7 operates, causing the alarm 9 to give an alarm.
[0024] The utility model can timely reflect whether the pipeline 1 is blocked, remind the staff, facilitate the staff to take dredging measures, avoid equipment damage, ensure that the production rhythm is not affected, reduce the maintenance cost, and greatly improve the use convenience.
[0025] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
