Description

A nozzle structure for a filling machine Technical Field

[0001] This utility model relates to the field of nozzle technology, and more specifically, to a nozzle structure for a filling machine. Background Technology

[0002] The nozzle of a filling machine is a key component that directly contacts honey at the end of the machine. Its core function is to act as a precise outlet for the honey, responsible for quantitatively and controllably filling liquid, paste, or powdered honey from the storage tank or metering system into the container. Through precise orifice design, valve control, and sealing structure, it ensures a drip-free, accurate, and controllable filling process, and adapts to different container openings and honey characteristics. It is widely used in production lines in the food and beverage, daily chemical, and pharmaceutical industries.

[0003] However, in actual use, when filling honey, because honey is viscous and easily crystallizes, bacteria can easily grow when there is residual honey. Cleaning requires stopping the machine, which increases costs. Therefore, it is necessary to automatically clean the internal parts during filling intervals or when changing products to effectively remove residual honey, avoid cross-contamination between batches, reduce downtime caused by cleaning, and effectively deal with honey adhesion. It is also necessary to automatically remove residual honey inside the nozzle to prevent it from drying, crystallizing, and causing blockage. Summary of the Invention

The short pipe 8 can transmit the gas in the annular air pipe 7 to a high-pressure air curtain nozzle 9. One end of the short pipe 8 penetrates the inner wall of the filling nozzle 1 and extends into it. The high-pressure air curtain nozzle 9 is used to spray a high-pressure air curtain to cut the honey.

[0030] In some embodiments, as shown in FIG2, the self-cleaning mechanism includes a self-cleaning housing 10 fixedly disposed on the top of the feed nozzle cavity 2, the self-cleaning housing 10 having a cleaning chamber 11 inside, the cleaning chamber 11 being made of stainless steel, and a vent pipe 12 being provided through the top of the self-cleaning housing 10 for spraying gas downwards.

[0031] In some embodiments, as shown in FIG3, the vent pipe 12 is provided with a solenoid valve 13 inside, the solenoid valve 13 is used to control the gas, and the top of the vent pipe 12 is provided with an air inlet connecting pipe 14, which is used to connect to an external gas source.

[0032] In some embodiments, as shown in FIG4, a miniature electric push rod 15 is fixedly provided inside the cleaning chamber 11. The miniature electric push rod 15 is used to drive the displacement of the isolation baffle 16. The bottom of the miniature electric push rod 15 is fixedly provided with the isolation baffle 16. The isolation baffle 16 is used to isolate the honey in the feed pipe 3 to prevent the honey in the feed pipe 3 from getting wet and contaminated. An annular water spray pipe 17 is provided inside the cleaning chamber 11. The annular water spray pipe 17 is made of engineering plastic.

[0033] In some embodiments, as shown in FIG1, an inclined high-pressure nozzle 18 is provided inside the annular water spray pipe 17. The high-pressure nozzle 18 is used to spray a high-pressure water jet to clean the discharge nozzle cavity 2 and the filling discharge nozzle 1. A water supply pipe 19 is provided through one side of the annular water spray pipe 17. The water supply pipe 19 is a flexible plastic tube. One end of the water supply pipe 19 extends from the cleaning shell 10 to the outside. A quick connector 20 is connected through one end of the water supply pipe 19. The quick connector 20 is used to quickly connect to an external water source. An infusion pipe 21 is provided at the bottom of the water supply pipe 19. The infusion pipe 21 is used to transmit cleaning fluid.

[0034] In some embodiments, as shown in FIG5, one end of the infusion tube 21 extends through the cleaning housing 10 and into the cleaning chamber 11, through which a spray head 22 is provided. The spray head 22 can be used to spray cleaning liquid onto the feed nozzle chamber 2 and the filling feed nozzle 1. The other end of the infusion tube 21 is connected to a quick connector 23.

[0035] The working principle of this utility model is as follows: First, the check valve 4 is opened, allowing honey to enter the feed pipe 3 through the inlet 5. The honey then continues to flow into the feed nozzle cavity 2. Next, the solenoid valve 13 of the vent pipe 12 at the top of the feed nozzle cavity 2 is opened, allowing external gas to enter the inlet connecting pipe 14 through the inlet, then the vent pipe 12, and finally the feed nozzle cavity 2. The downward pressure generated by the gas pushes the honey flowing into the feed nozzle cavity 2, accelerating it into the filling nozzle 1. From the filling nozzle 1, the honey enters the container below, initiating the filling process. The high-pressure air curtain nozzle 9 outside the feed nozzle 1 quickly cuts off and blocks the honey, preventing it from forming threads. After working for a period of time, it begins self-cleaning. First, it closes the check valve 4 of the feed pipe 3 to stop the honey from flowing into the feed pipe 3. Then, it activates the high-pressure air curtain nozzle 9 inside the feed pipe 3 to cut off and block the honey. Next, it activates the micro electric push rod 15, which moves the isolation baffle 16 downwards. When it reaches the lowest point, the isolation baffle 16 blocks the feed port at one end of the feed pipe 3. Then, it opens the infusion tube 21 inside the cleaning chamber 11. The cleaning solution enters the infusion pipe 21 and then the spray head 22. The cleaning solution is then sprayed downwards from the nozzle of the spray head 22. Under the action of the gas introduced through the upper vent pipe 12, the cleaning solution covers the entire inner wall of the discharge nozzle cavity 2 and the filling discharge nozzle 1. Then, the water infusion pipe 19 is opened, and external water enters the water infusion pipe 19, flowing into the annular water spray pipe 17. High-pressure water jets are then sprayed onto the inner wall of the discharge nozzle cavity 2 and the filling discharge nozzle 1 through the high-pressure nozzle 18 for cleaning. Finally, the infusion pipe 21 is closed, and no further cleaning of the discharge nozzle cavity 2 and the filling discharge nozzle 1 continues. Cleaning fluid is sprayed, and then a high-pressure water jet continues to clean the discharge nozzle cavity 2 and the filling nozzle 1. After rinsing and removing all residue, the water supply pipe 19 is closed. Then, under the action of the gas introduced through the vent pipe 12 above the discharge nozzle cavity 2, the water inside the discharge nozzle cavity 2 and the filling nozzle 1 is blown out. After the discharge nozzle cavity 2 and the filling nozzle 1 are dry, the micro electric push rod 15 is activated. The micro electric push rod 15 moves the isolation baffle 16 upward, and then the check valve 4 inside the discharge pipe 3 is opened to continue the filling process.
