Technical Field

[0001] The utility model belongs to the technical field of nitrogen filling, and in particular relates to nitrogen filling packaging equipment with the function of increasing nitrogen concentration. Background Art

[0002] Nitrogen-filled packaging is used in various industries such as fresh fruit food, pharmaceutical chemicals and electronic components. After vacuum evacuation and nitrogen-filled packaging, the product's pressure resistance is greatly enhanced, and at the same time, it can achieve the effect of anti-oxidation, anti-corrosion, anti-mildew and moisture-proof preservation and storage. The nitrogen filling and packaging equipment currently on the market is difficult to maintain a high concentration of nitrogen inside, resulting in a low nitrogen concentration that easily affects the product packaging effect. At the same time, the nitrogen filling and packaging equipment currently on the market does not have the functions of noise reduction and nitrogen blocking, resulting in the equipment generating certain noise when in use, thereby affecting the surrounding staff, and when the equipment is not in use, the internal nitrogen will be lost through the nitrogen filling port, resulting in nitrogen waste. Therefore, a nitrogen filling and packaging equipment with the function of increasing nitrogen concentration is needed to solve the above problems. Utility Model Content

[0010] As a preferred implementation, a through opening is opened in the mounting plate, and the flow guide pipe is located in the through opening.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The utility model is provided with a nitrogen filling device, a flow guide pipe, an electric push rod, a telescopic noise reduction cotton, a first rack, a gear, a second rack and a blocking block. The nitrogen filling device utilizes the flow guide pipe to input nitrogen into the device body through the nitrogen inlet pipe to ensure the concentration of nitrogen in the device body. At the same time, when the electric push rod drives the telescopic noise reduction cotton to move downward to a suitable position, the device body can be surrounded, thereby effectively reducing the noise generated when the device body is in use. In addition, the electric push rod can drive the first rack to move downward synchronously, so that the gear meshing with the first rack can be in a rotating state, which promotes the gear meshing with the gear to rotate. The second rack gear can drive the blocking block to move upward, so that the nitrogen filling port of the nitrogen filling tube loses the blocking of the blocking block and can be in an open state. Then, this device enables the equipment body to maintain a high concentration of nitrogen inside, preventing the low nitrogen concentration from affecting the product packaging effect. At the same time, this device enables the equipment body to have the functions of noise reduction and nitrogen blocking, thereby greatly reducing the noise generated by the equipment body when in use, thereby effectively avoiding the noise from affecting the surrounding staff, and when the equipment body is not in use, the internal nitrogen is difficult to be lost through the nitrogen filling tube to cause nitrogen waste;

[0013] The utility model provides a first through hole and a second through hole, which allow the first rack and the second rack to have space to move up and down, thereby preventing the first rack and the second rack from being blocked by the mounting plate and unable to move smoothly, thereby ensuring that the working process between the first rack, the gear and the second rack can be smoothly realized.
