Description

Technical Field

[0001] The present invention relates to the technical field of packaging equipment, in particular to a cup tea packaging machine. Background Art

[0002] Traditionally, tea is packaged in plastic bags and ceramic pots. These packaging methods separate the tea leaves from the cups they are brewed in. This makes it inconvenient to place tea leaves in each cup when gathering in large groups, such as at meetings. This led to the emergence of cup tea, which is a disposable cup filled with tea leaves, sealed with a mesh, and then poured with boiling water to create a cup of tea. With the fast-paced pace of life, cup tea is becoming increasingly popular. However, existing cup tea packaging methods are limited by packaging costs and automation technology, and are generally divided into manual and semi-automated packaging. These two packaging methods have high labor costs, low production efficiency, and are not clean or hygienic. Summary of the Invention

The inner wall of the cup discharge receiving ring 735 is circumferentially provided with a plurality of cup clamping assemblies 736, and a plurality of receiving guide rods 737 are fixed vertically along the circumference of the top.

[0062] When the cup discharge mechanism 7 is in operation, the lifting mechanism 71 first lifts the two sealed cups upward and receives them into the discharge mechanism 73. The cup clamping assembly 736 of the discharge mechanism 73 holds the cups in place. After receiving the cups, the discharge mechanism 73 moves horizontally to deliver the cups to the top of the cup discharge channel 72. The cup clamping assembly 736 then returns to its original position and the cups are discharged from the cup discharge channel 72. The purpose of providing two sets of cup discharge channels 72 is to enable the discharge mechanism 73 to discharge the cups alternately from left to right, thereby improving the discharge efficiency.

[0063] The working principle of the present invention is as follows: the stacked cups fall into the lower cup mechanism 3 from above, and the lower cup mechanism 3 sends the cups into the fork-type conveyor mechanism 2 by clamping the cup support assembly 32 and clamping the lower cup assembly 31 (i.e., separating the stacked cups one by one). The conveyor mechanism 2 sends the cups to the bottom of the blanking mechanism 4, and the weighed tea leaves fall into the cups from the blanking mechanism 4, and then the cups filled with tea leaves are conveyed to the bottom of the film-loading mechanism 5; at the same time, the film cutting mold 53 cuts the sealing film, and the film-loading mechanism 58 sucks the cut sealing film and turns it 180° and places it above the cup mouth below, and continues to be conveyed by the fork-type conveyor mechanism 2 to the bottom of the film-sealing mechanism 6, and the film-sealing mechanism 6 presses the sealing film on the cup mouth downward so that the sealing film is located at the bottom of the cup, and continues to be conveyed by the fork-type conveyor mechanism 2 to the outlet end, and after the product is lifted upward by the lifting mechanism 71, the product is dropped into the lower cup channel 72 by the discharging mechanism 73, completing the packaging of the cup tea.
