With the improvement of people's living standards, the tea culture has become more and more popular. The tea culture has promoted the tea production. Generally, after tea is picked, it can only form a finished product with sellable quality through various processing techniques. After the tea is taken out of the storage warehouse and packaged, it is transported to the market according to a certain weight. In this process, tea packaging equipment will be used.

[0003] Chinese Patent with the authorization announcement number CN217673313U discloses an automatic weighing device for tea packaging. One end of the support is fixedly connected with an L-shaped support plate. The top of the L-shaped support plate is fixedly connected with a fixed frame. A limiting plate is slidably connected in the fixed frame. One side top of the limiting plate away from the support is in contact with a support plate. The support plate is fixedly connected to the fixed frame, and a feeding component is arranged on the top of the support plate. A storage barrel is embedded on the limiting plate, and an elastic component is arranged at the bottom end of one side of the storage barrel. The utility model feeds materials into the storage barrel through the feeding component, and drives the limiting block to reciprocate through a cylinder, so that the limiting plate drives the storage barrel to reciprocate on the L-shaped support plate to realize quantitative feeding. When the storage barrel slides away from the L-shaped support plate, the light thin plate is opened through the elastic component, and the tea in the storage barrel falls into the packaging bag, and is detected by a weight sensor to avoid the weight of the tea exceeding the error value.
