[0002] A nasal spray filling machine is a device specifically designed to fill liquid medicines into spray containers. It is characterized by high efficiency and precision, and can automatically complete the entire process of filling, capping, and labeling, greatly improving production efficiency. Nasal spray filling machines typically employ advanced technology and precise metering systems to ensure the stability of the quality and dosage of each bottle of spray.
[0003] The current product is prone to drug delivery device failure after filling, resulting in the inability to spray the medicine. Analysis shows that this is due to the missing straw, which necessitates testing the overall structural integrity. However, relying solely on manual inspection for missing straws can easily lead to missed detections, resulting in reduced testing efficiency.
[0004] To address this issue, we propose an automatic detection device for missing straws in nasal spray filling machines. Utility Model Content

A limiting rod is fixedly connected to the inner wall of the locking block. A threaded rod is threadedly connected to the inner wall of the fixing rod, and the bottom end of the threaded rod contacts the outer surface of the locking block. Two nozzle bodies are arranged on the outer side of the vibrator body, and the outer surface of each nozzle body contacts the outer surface of the limiting rod. The control panel is electrically connected to the vibrator body via wires.
[0008] Preferably, a reinforcing frame is fixedly connected to the outer surface of the control panel, and the bottom surface of the reinforcing frame is fixedly connected to the upper surface of the base plate.
[0009] Preferably, a reinforcing plate is fixedly connected to the outer surface of the support rod, and the bottom surface of the reinforcing plate is fixedly connected to the upper surface of the base plate.

Detailed Implementation
[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0022] Reference Figures 1-4 An automatic straw missing detection device for a nasal spray filling machine includes a base plate 1. A vibrator body 15, a protective shell 8, a control panel 9, a limiting plate 14, and a support rod 5 are fixedly connected to the upper surface of the base plate 1. A limiting baffle 3 is fixedly connected to the end of the support rod 5 away from the base plate 1. A reinforcing frame 10 is fixedly connected to the outer surface of the control panel 9. The bottom surface of the reinforcing frame 10 is fixedly connected to the upper surface of the base plate 1. The reinforcing frame 10 can reinforce the control panel 9 and the base plate 1, thereby enhancing the stability of the device.
[0023] Four support bases 11 are fixedly connected to the bottom surface of the base plate 1. Two fixed frames 13 are fixedly connected to the outer surface of the limiting baffle 3. Four guide rods 2 are fixedly connected to the inner walls of the two fixed frames 13. A reinforcing plate 7 is fixedly connected to the outer surface of the support rod 5. The bottom surface of the reinforcing plate 7 is fixedly connected to the upper surface of the base plate 1. The reinforcing plate 7 can fix the support rod 5 and the base plate 1 to prevent them from shifting their position during use.
[0024] A fixing rod 16 is fixedly connected to the outer surface of the oscillator body 15. A locking block 18 is snapped into the inside of the fixing rod 16. A limit rod 17 is fixedly connected to the inner wall of the locking block 18. A threaded rod 19 is threadedly connected to the inner wall of the fixing rod 16. Four fixing bolts 6 are threadedly connected to the inner wall of the reinforcing plate 7. The outer surface of each fixing bolt 6 is threadedly connected to the inner wall of the base plate 1. The fixing bolts 6 can limit the position of the reinforcing plate 7 and play a fixed and limiting role.
[0025] The bottom end of the threaded rod 19 contacts the outer surface of the locking block 18. Two nozzle bodies 20 are provided on the outer side of the vibrator body 15. A reinforcing ring 4 is fixedly connected to the outer surface of the support rod 5. The outer surface of the reinforcing ring 4 is fixedly connected to the inner wall of the limiting baffle 3. The reinforcing ring 4 can reinforce the support rod 5 and the limiting baffle 3 to prevent them from swaying during operation.
[0026] The outer surface of each nozzle body 20 is in contact with the outer surface of the limit rod 17. The control panel 9 is electrically connected to the vibrator body 15 via wires. Two fixing rings 12 are fixedly connected to the outer surface of each support base 11. The top of each fixing ring 12 is fixedly connected to the bottom surface of the base plate 1. The fixing rings 12 can fix the support base 11 and the base plate 1, effectively preventing them from shaking or shifting during operation.
[0027] The working principle of this utility model is as follows: In use, firstly, the locking block 18 is installed on the fixing rod 16, and its position is adjusted. After the position adjustment is completed, the position of the locking block 18 is fixed by rotating the threaded rod 19. Then, the vibrator body 15 is started through the control panel 9, which in turn transports the nozzle body 20. During the transport process, the position of the nozzle body 20 is restricted by the limiting baffle 3, which serves as a fixed limit, enhancing the practicality of the device. When the nozzle body 20 moves to the automatic detection area, the nozzle body 20... The movement path will be restricted by the limiting rod 17 and the limiting plate 14. During the conveying process of the vibrator body 15, the nozzle body 20 without a suction tube will tilt and fall due to its structure. However, the nozzle body 20 with a suction tube can be prevented from tilting and falling because the long suction tube can provide a downward force. It can then be conveyed to the guide rod 2 for further processing. This allows for automatic detection of whether the nozzle body 20 is missing a suction tube, effectively avoiding the problem of missed detections and reduced detection efficiency caused by relying solely on manual detection of missing suction tubes.
