Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of filling equipment, in particular to a liquid-leakage-free canning device. Background Art
[0002] In the field of filling production technology, the filling head fills the liquid into the packaging bottle. Since the structure and installation of the existing filling head are relatively simple, it is convenient to fill at room temperature. However, when hot filling is used, the temperature of the liquid changes. During filling, the sealing material between the outer wall of the filling head and the filling head jacket will expand as the temperature rises, causing the filling head jacket and the filling head to lock. When the temperature drops, leakage will occur again, and normal work cannot be done at all. In order to ensure the smooth progress of high-temperature filling, it is necessary to grind the sealing material to the premise that it is very loose with the filling head jacket before using it. The temperature control requirements of the material are also very high. If the temperature drops a little, it must be heated and supplemented in time, otherwise there will be serious leakage. 10% to 15% of the material will be lost during production every day, resulting in the filling workshop being full of materials. These nutrient materials will breed bacteria when they are in contact with the air for a long time. In order to avoid the growth of bacteria, the filling room must be cleaned every half an hour, which wastes materials and adds production time. Therefore, in order to solve the original problem, the previously used filling head is improved so that it can be sealed and filled without leakage. Utility Model Content
[0003] In view of the above-mentioned prior art, the utility model provides a non-leakage canning device, which has the functions of no leakage during high-temperature filling, easy installation and reduced production cost.

[0012] By optimizing the structural shape of the connection between the filling head and the filling head jacket, the auxiliary sleeve and the filling head jacket are matched and connected with screws, and then sealed and connected by a silicone sleeve made of thin silicone tube. The filled packaging bottle slowly lifts up the filling head, the filling head jacket compresses the spring downward, and the filling head jacket and the sealing cover plate are separated. At this time, the liquid in the liquid tank enters the filling channel through the liquid inlet hole and enters the packaging bottle from the liquid outlet hole. The air in the bottle is discharged through the air pipe until the liquid level seals the air pipe opening in the bottle, and the air no longer discharges and the liquid no longer enters the bottle. The packaging bottle slowly descends until the process is completed.
