[0019] In the following description, embodiments of the one-way valve filling structure for a food production line according to the present invention will be described with reference to the accompanying drawings.

[0020] Figure 1-3This invention illustrates a one-way valve filling structure for a food production line according to an embodiment of the present invention. The structure includes a one-way valve tube 1: a gas inlet pipe 2 is fixedly connected to the top of the one-way valve tube 1; a valve core 3 is fixedly connected to the left side of the inner cavity of the one-way valve tube 1; a valve core 4 is fixedly connected to the right side of the inner cavity of the one-way valve tube 1; a check valve assembly 5 is provided in the inner cavity of the one-way valve tube 1; the check valve assembly 5 includes a first plug cavity 51 opened to the right of the valve core 3; the first plug cavity 51 and the feeding channel 56 are both connected to the inner cavity of the one-way valve tube 1; the diameters of the first plug ball 52 and the second plug ball 55 are the same as the inner diameters of the first plug cavity 51 and the second plug cavity 54, respectively; through the cooperative use of the first plug ball 52 and the second plug ball 55, the inner walls of the first plug cavity 51 and the second plug cavity 54 are sealed, thereby controlling the feeding and stopping of food, ensuring the stability of the food filling process; the inner cavity of the first plug cavity 51 is provided with a slidable plug ball 52; the first plug ball 52... A feed channel 53 is provided at the bottom of the inner cavity of the plug cavity 51. A docking plate 6 is installed on both sides of the one-way valve tube 1. A sealing ring 9 is provided between the one-way valve tube 1 and the docking plate 6. An arc-shaped groove 10 adapted to the sealing ring 9 is provided on both sides of the one-way valve tube 1. Through the cooperation of the sealing ring 9 and the arc-shaped groove 10, the one-way valve tube 1 and the docking plate 6 are sealed, thereby effectively preventing gas leakage in the inner cavity of the one-way valve tube 1 and avoiding food leakage. The left end of the docking plate 6 on the left side is connected to the feed pipe 7, which is connected to the feed channel 53. A second plug cavity 54 is provided at the top of the valve core 4. A feed pipe 8 is connected to the right end of the docking plate 6 on the right side, which is connected to the second plug cavity 54. A slidable plug ball 55 is provided in the inner cavity of the second plug cavity 54. A feed channel 56 is provided at the bottom of the inner cavity of the second plug cavity 54.

[0021] Working principle: When using this utility model, the user connects the air inlet pipe 2 to the air end of the external air pressure device, connects the feed pipe 7 to the food storage bin, and places the container directly below the feed pipe 8.

[0022] Pressurization by the pneumatic equipment: Positive pressure is generated in the inner cavity of the one-way valve pipe 1 and the air inlet pipe 2, which in turn generates positive pressure in the inner cavity of the first plug cavity 51, the second plug cavity 54 and the feeding channel 56. At this time, under the action of air pressure, the bottom of the surface of the first plug ball 52 is pressed against the bottom of the inner cavity of the first plug cavity 51, which seals the feeding channel 53, so that the food stops feeding from the inner cavity of the feeding pipe 7 and the inner cavity of the feeding channel 53 into the inner cavity of the one-way valve pipe 1. The second plug ball 55 slides upward under the action of air pressure and reaches the top of the inner cavity of the second plug cavity 54. At this time, the feeding channel 56, the second plug cavity 54 and the feeding pipe 8 are in a connected state, and the food can be discharged from the inner cavity of the feeding pipe 8.

[0023] Air pressure reduction: Negative pressure is generated in the inner cavities of the one-way valve pipe 1 and the air inlet pipe 2, causing negative pressure in the inner cavities of the first plug cavity 51, the feed channel 53, the second plug cavity 54, and the feeding channel 56. Under this air pressure, the top of the surface of the first plug ball 52 is pressed tightly against the top of the inner cavity of the first plug cavity 51 by the squeezing action of the food entering through the feed channel 53. At this time, the food sequentially enters the inner cavity of the one-way valve pipe 1 from the feed pipe 7, the feed channel 53, and the inner cavity of the first plug cavity 51. Simultaneously, the second plug ball 55 is subjected to pressure from the feeding channel 56 and the second plug cavity 56. 4. Due to the negative pressure in the inner cavity, the ball slides downwards. When the horizontal axis of the second plug ball 55 is on the same horizontal plane as the horizontal inner axis of the feeding pipe 8, the second plug ball 55 seals the feeding pipe 8. At this time, the feeding pipe 8 stops adding food. Since the second plug cavity 54 still has a certain downward space, the second plug ball 55 continues to slide down. At this time, a negative pressure is generated above the inner cavity of the second plug cavity 54, which in turn causes a negative pressure to be generated in the inner cavity of the feeding pipe 8, which draws back the food in the inner cavity of the feeding pipe 8, thereby preventing the food from dripping.

[0024] In summary, the one-way valve filling structure of this food production line connects to a pneumatic device via an air inlet pipe 2, controlling the generation of positive and negative pressure gas within the one-way valve pipe 1 to transport the food. Simultaneously, with the coordinated use of valve core 3, valve core 4, and check valve assembly 5, the food is transported and opened / closed, while the food at the bottom of the feed pipe 8 is drawn back, thus achieving stable and smooth feeding and automatic back suction to prevent dripping.
