[0003] To address the aforementioned issues, this invention provides a hopper residual material monitoring and alarm device, which allows for convenient observation of the hopper's remaining material level at any time, enabling timely replenishment of plastic granules to maintain efficient production.

[0004] The technical solution of this utility model is as follows:

[0005] A hopper residual material monitoring and alarm device includes:

[0006] The hopper is located at the top of the upright frame and includes a storage section, a leakage section and a discharge section from top to bottom. A transparent observation window is provided on the storage section. The upright frame includes a support plate and multiple elastic telescopic columns, with the two ends of the elastic telescopic columns connected to the hopper and the support plate, respectively.

[0007] The monitoring equipment is located on the outside of the transparent observation window;

[0008] The alarm device includes a mounting column, an audible and visual alarm, and an extrusion block. The mounting column is located on one side of the hopper on the support plate. The audible and visual alarm is located on the mounting column. The extrusion block is located on the storage section near the mounting column. The mounting column near the hopper has a switch button for the audible and visual alarm. When the amount of material remaining in the hopper is higher than a set threshold, the extrusion block is lower than the switch button. When the amount of material remaining in the hopper is within the set threshold range, the extrusion block is exactly against the switch button.

[0009] In a further technical solution, a connecting plate is provided between the storage section and the leakage section. The elastic telescopic column includes an outer rod, an inner rod and a spring. The top end of the outer rod is telescopically sleeved on the outside of the inner rod, and the bottom end is connected to a support plate. The top end of the inner rod is connected to the bottom side of the connecting plate. The spring is sleeved on the outside of the inner rod, and its two ends are respectively connected to the top end of the outer rod and the bottom side of the connecting plate.

[0010] In a further technical solution, the monitoring equipment includes an installation compartment and a camera located inside the installation compartment, with the installation compartment positioned outside a transparent observation window.

[0011] In a further technical solution, the area of ​​the transparent observation window is larger than the area of ​​the side of the installation compartment facing the transparent observation window.

[0012] In a further technical solution, the installation chamber is detachably connected to the side wall of the storage section at the edge of the transparent observation window.

[0013] In a further technical solution, the top of the storage section is provided with a cover, one side of the cover is hinged to the storage section, and the side of the storage section away from the hinged cover is provided with a locking buckle.

[0025] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0026] Example:

[0027] like Figures 1-2 As shown, a hopper residual material monitoring and alarm device includes a hopper, monitoring equipment, and alarm equipment. A support frame is erected at the plastic extruder, including a support plate 10 and multiple vertically arranged elastic telescopic columns surrounding a connecting plate 50. The hopper is located on top of the support plate 10 and includes a storage section 20, a discharge section 30, and a discharge section 40 from top to bottom. The bottom end of the discharge section 40 is provided with a corrugated pipe 41 connected to the feed inlet of the plastic extruder, allowing for a large telescopic space during hopper lifting and lowering. A transparent observation window 21 is provided on the storage section 20. A connecting plate 50 connected by bolts is provided between the storage section 20 and the discharge section 30. The elastic telescopic columns include an outer rod 61, an inner rod 62, and a spring 63. The top end of the outer rod 61 is telescopically sleeved on the outside of the inner rod 62, and the bottom end is connected to the support plate 10. The top end of the inner rod 62 is connected to the bottom side of the connecting plate 50, and the spring 63 is sleeved on the inner rod 62. 2. The outer side is connected to the top of the outer rod 61 and the bottom of the connecting plate 50 at both ends respectively; the monitoring equipment includes the installation chamber 70 and the camera 71 installed in the installation chamber 70. The installation chamber 70 is located outside the transparent observation window 21; the alarm equipment includes the installation column 81, the audible and visual alarm 82 and the extrusion block 83. The installation column 81 is located on one side of the hopper on the support plate 10. The audible and visual alarm 82 is located on the installation column 81. The extrusion block 83 is located on the side of the storage section 20 near the installation column 81. The side of the installation column 81 near the hopper is provided with the switch button 84 of the audible and visual alarm 82. When the amount of material remaining in the hopper is higher than the set threshold, the extrusion block 83 is lower than the switch button 84. When the amount of material remaining in the hopper is within the set threshold range, the extrusion block 83 is exactly against the switch button 84. The switch button 84 can be in the shape of an arc protrusion, so that the extrusion block 83 can approach and gradually press down from the side of the switch button 84.

[0028] The working principle of the above technical solution is as follows:

[0029] During use, the amount of plastic granules in the hopper gradually decreases, reducing the overall weight of the hopper. This reduces the pressure on the spring 63, causing it to gradually extend and extend the telescopic rod. The hopper slowly rises, and the extrusion block 83 gradually approaches the switch button 84. When it reaches the set threshold range, the extrusion block 83 presses the switch button 84, activating the audible and visual alarm 82 to remind the staff to replenish the material. During production, the amount of plastic granules in the hopper can also be monitored in real time through monitoring equipment, facilitating remote viewing and ensuring continuous production.

[0030] In another embodiment, such as Figure 1-2 As shown, the area of ​​the transparent observation window 21 is larger than the area of ​​the side of the installation chamber 70 facing the transparent observation window 21. The installation chamber 70 can be set on one side of the transparent observation window 21. The edge of the installation chamber 70 can be provided with a connecting edge 73, the connecting edge 73 is provided with a connecting hole, and a corresponding threaded hole is provided on the edge of the transparent observation window 21, so that the installation chamber 70 and the hopper can be detachably connected by bolt connection.

[0031] The transparent viewing window 21 allows for selective direct viewing or viewing of the remaining material inside the hopper via the camera 71. The installation chamber 70 can be removed for maintenance of the camera 71 and cleaning of the transparent viewing window 21.

[0032] In another embodiment, such as Figure 1 and Figure 3 As shown, the top of the storage section 20 is provided with a cover 22. The side of the cover 22 away from the mounting post 81 is hinged to the storage section 20. The side of the storage section 20 away from the hinged cover 22 is provided with a locking buckle 90. The locking buckle 90 includes a support block 91 and a buckle block. The support block 91 is located on the top side wall of the storage section 20. A movable groove 92 is opened in the middle of the support block 91. Rotating shafts are provided on both sides of the middle of the buckle block, which are rotatably connected to the side walls of the movable groove 92. Torsion springs connected to the support block 91 are provided on the rotating shafts. The two ends of the buckle block are buckle heads. 93 and extrusion head 94 are provided. Extrusion head 94 is located near mounting post 81. Mounting post 81 is provided with a stop 85 that can abut against extrusion head 94. When the buckle locks cover 22, buckle head 93 is above cover 22. Torsion spring applies a force to buckle head 93 to press down cover 22. When the amount of material remaining in hopper is higher than the set threshold, extrusion head 94 is lower than stop 85. When the amount of material remaining in hopper is within the set threshold range, extrusion head 94 is squeezed downward by stop 85 and tilts downward. At this time, buckle head 93 tilts upward to facilitate opening cover 22.

[0033] Before and after feeding, the top of the hopper can be covered by the cover 22 and locked by the locking buckle 90 to prevent external impurities from entering and affecting product quality. When the audible and visual alarm 82 is triggered, the locking buckle 90 can also be automatically opened by squeezing to facilitate opening the cover 22.

[0034] In another embodiment, such as Figure 1As shown, the pressing block 83 can be a roller. Rolling pressing reduces wear on the switch button 84.

[0035] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
