Description

Technical Field

[0001] This utility model relates to the field of tea processing technology, and in particular to a nitrogen-filled tea preservation device. Background Technology

[0002] Tea is a beverage rich in polyphenols, caffeine, amino acids, vitamins, and other nutrients. It is widely loved for its unique flavor and health benefits. However, tea is easily spoiled during storage due to various factors such as oxygen, moisture, light, and temperature. To maintain tea quality and extend its shelf life during processing, effective preservation measures are necessary. Nitrogen, an inert gas with stable chemical properties, does not readily react with other substances. Filling tea packaging with nitrogen can expel oxygen from the packaging, reducing its oxidative effect on the tea and thus slowing down the spoilage process, preserving the tea's color, aroma, flavor, and nutrients. Therefore, a nitrogen-filled tea preservation device is required when filling the inside of tea canisters with nitrogen.

[0003] Modern nitrogen-filled tea preservation devices can basically meet people's needs, but there are still some problems, as follows: When using them, the position of the air inlet may vary depending on the size and model of the tea canister, so the position of the tea canister needs to be adjusted for nitrogen filling. Utility Model Content

[0004] The purpose of this invention is to provide a nitrogen-filled tea preservation device to solve the problem that existing nitrogen-filled tea preservation devices are difficult to adjust the position of the tea canister.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a nitrogen-filled tea preservation device, including a box body;

[0006] The bottom of the box is equipped with support legs, the top of the box is equipped with a workbench, the top of the workbench is equipped with a mounting frame, and the top of the mounting frame is equipped with a nitrogen tank.

[0007] An air pump is installed at the bottom of the nitrogen tank, a hydraulic cylinder is installed at the top of the mounting bracket, a lifting block is installed at the bottom of the hydraulic cylinder, and a nitrogen filling head is installed at the bottom of the lifting block.

[0008] A movable structure is installed at the top of the workbench. The movable structure includes a second guide rod installed at the top of the workbench and a second movable block installed at the top of the second guide rod.

[0009] In use, during the initial processing, the vacuum-sealed tea canister is placed on top of the first moving block. After adjusting the position of the tea canister, the hydraulic cylinder will work to drive the lifting block to rise and fall. As the lifting block rises and falls, the nitrogen filling head is inserted into the tea canister. Then, the air pump will work to draw out the nitrogen from the nitrogen tank and fill the tea canister with nitrogen through the nitrogen filling head.

[0010] Furthermore, a second fixing screw is installed on both sides of the second movable block, a first movable block is installed on the top of the second movable block, a first guide rod is installed on the bottom of the first movable block, and a first fixing screw is installed on both sides of the first movable block. The movable structure can adjust the position of the tea canister.

[0011] Furthermore, the first fixing screw and the first moving block form a threaded connection. The first fixing screw is symmetrically distributed about the central axis of the first moving block. Tightening the first fixing screw can fix the first moving block.

[0012] Furthermore, the outer diameter of the second guide rod is smaller than the inner diameter of the second moving block, and the second guide rod and the second moving block form a sliding structure, so that the second guide rod can guide the second moving block.

[0013] Furthermore, a limiting structure is installed at the top of the movable structure. The limiting structure includes a fixed plate installed at the top of the movable structure, a threaded rod passing through the middle of the fixed plate, a rotating block installed on one side of the threaded rod, and a positioning block installed on one side of the threaded rod. The limiting structure can limit the movement of the tea canister.

[0014] Furthermore, the outer side wall of the threaded rod is uniformly provided with external threads, and the inner side wall of the fixing plate is uniformly provided with internal threads that cooperate with the external threads. The threaded rod and the fixing plate are threadedly connected, and the position of the threaded rod can be adjusted by rotating the threaded rod.

[0015] Furthermore, the bottom end of the lifting block is equipped with a disassembly and assembly structure. The disassembly and assembly structure includes a connecting block installed at the bottom end of the lifting block, and a connecting plate is provided on one side of the connecting block. An installation screw passes through the middle of the connecting plate. The disassembly and assembly structure can fix the nitrogen filling head.

[0016] The advantages of the nitrogen-filled tea preservation device provided by this utility model are as follows: during processing, the tea canister can be limited by the limiting structure to prevent the tea canister from shifting; the position of the tea canister can be adjusted by the moving structure to adapt to different situations; and the nitrogen filling head can be replaced and installed by the disassembly and assembly structure.

[0017] By installing a first moving block at the top of the second moving block, the tea canister can be limited to the top of the first moving block. The first moving block can move along the first guide rod to move the tea canister. The first fixing screw can be tightened to fix the first moving block. The second moving block can move along the second guide rod to adjust the position of the second moving block and the tea canister. The second fixing screw can be tightened to fix the second moving block. In this way, the position of the tea canister can be adjusted by moving the moving blocks, allowing the device to fill different tea canisters with nitrogen, thereby achieving the purpose of the nitrogen-filling preservation device for tea that is easy to adjust the position of the tea canister.

[0018] A fixed plate is installed at the top of the second moving plate. The fixed plate and the threaded rod form a threaded connection. Rotating the rotating block will drive the threaded rod to rotate. The rotation of the threaded rod will drive the threaded rod to move. The movement of the threaded rod will drive the positioning block on one side to move. The positioning block is made of rubber material. The movement of the three positioning blocks can clamp the tea canister in the middle and limit the tea canister. This achieves the purpose of the nitrogen-filled tea preservation device to limit the tea canister. Attached Figure Description
