[0028] The lifting assembly 4 includes a drive motor 41. The lower surface of the drive motor 41 is fixedly connected to the inner wall of the bottom surface of the fixed cover 3. A rotating rod 42 is fixedly installed at the output end of the drive motor 41. A threaded rod 43 is fixedly installed at one end of the rotating rod 42. A threaded plate 44 is threadedly installed on the outer surface of the threaded rod 43. A placement plate 45 is fixedly installed at one end of the threaded plate 44. A limiting plate 46 is fixedly installed on the outer surface of the placement plate 45. One end of the limiting plate 46 is slidably connected to the inner side wall of the fixed cover 3. An alarm light 47 is fixedly installed on the upper surface of the placement plate 45. A protective plate 48 is fixedly installed on the upper surface of the alarm light 47. An opening is provided on the upper surface of the fixed cover 3. The size of the alarm light 47 is adapted to the opening. A sealing ring 6 is fixedly installed on the inner wall of the top surface of the fixed cover 3.
[0029] The specific implementation method is as follows: The mounting base 1 is fixed in a suitable position by mounting holes 2 and bolts, thereby fixing the alarm device in a suitable position. Before feeding, the drive motor 41 drives the rotating rod 42 to rotate, and the rotating rod 42 drives the threaded rod 43 to rotate. Under the action of the thread, the threaded plate 44 drives the placement plate 45 to move under the limit of the limiting plate 46, thereby causing the placement plate 45 to drive the alarm light 47 to rise from the opening on the fixed cover 3. During the feeding process, the sensor monitors the plastic particles. When the wrong plastic particles are added, the signal is transmitted to the alarm light 47 and an alarm and flashing occur. When the alarm device is not in use, the alarm light 47 is retracted into the fixed cover 3. At this time, the alarm light 47 will drive the protective plate 48 to descend synchronously. The protective plate 48 seals the opening with the cooperation of the sealing ring 6.
[0030] The cleaning assembly 5 includes a drive gear 51 and a fixed ring 53. The inner wall of the drive gear 51 is fixedly connected to the outer surface of the threaded rod 43. A connecting block 54 is fixedly installed on the upper surface of the fixed ring 53. One end of the connecting block 54 is slidably connected to the inner wall of the top surface of the fixed cover 3. A driven gear 55 is fixedly installed on the outer surface of the fixed ring 53. The driven gear 55 meshes with the drive gear 51. A cleaning ring 52 is fixedly installed on the inner surface of the fixed ring 53.
[0031] The specific implementation method is as follows: During the retraction of the alarm light 47, the threaded rod 43 will drive the drive gear 51 to rotate. At this time, under the action of the driven gear 55, the fixed ring 53 will rotate under the limit of the connecting block 54. When the fixed ring 53 rotates, it will drive the cleaning ring 52 to rotate synchronously, so that the cleaning ring 52 cleans the outer surface of the alarm light 47 during the retraction of the alarm light 47.
[0032] Working principle: The mounting base 1 is fixed in the appropriate position through the mounting hole 2 and bolts, thereby fixing the alarm device in the appropriate position. Before feeding, the drive motor 41 drives the rotating rod 42 to rotate, and the rotating rod 42 drives the threaded rod 43 to rotate. Under the action of the thread, the threaded plate 44 drives the placement plate 45 to move under the limit of the limiting plate 46, thereby causing the placement plate 45 to drive the alarm light 47 to rise from the opening on the fixed cover 3. During the feeding process, the sensor monitors the plastic particles. When the wrong plastic particles are added, the signal is transmitted to the alarm light 47, triggering an alarm and flashing. When the device is not in use, the alarm light 47 is retracted into the fixed cover 3. At this time, the alarm light 47 will drive the protective plate 48 to descend synchronously. The protective plate 48, with the cooperation of the sealing ring 6, seals the opening. During the retraction of the alarm light 47, the threaded rod 43 will drive the drive gear 51 to rotate. At this time, under the action of the driven gear 55, the fixed ring 53 will rotate under the limit of the connecting block 54. When the fixed ring 53 rotates, it will drive the cleaning ring 52 to rotate synchronously. Thus, during the descent and retraction of the alarm light 47, the cleaning ring 52 cleans the outer surface of the alarm light 47.
[0033] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
