[0001] The utility model relates to the technical field of tea processing, in particular to tea sorting, packaging and plastic sealing equipment. Background Art

[0002] Tea, commonly known as tea, generally includes the leaves and buds of the tea tree. It is also known as tea, tea, tea, tea, and tea. Tea ingredients include catechins, cholesterin, caffeine, inositol, folic acid, and pantothenic acid, which are beneficial to health. Tea beverages made from tea are one of the three major beverages in the world. After the tea leaves are sorted and canned, in order to ensure the sealing of the cans, they need to be plastic-sealed, so corresponding packaging and plastic-sealing equipment has emerged.

[0003] During the plastic sealing process of existing tea cans, the plastic bag needs to be heated after wrapping the tea can to make the plastic bag fit better with the tea can. However, during the heating process of the existing plastic sealing equipment, the heating range of the plastic bag is not uniform enough, which easily leads to incomplete fitting.

When in use, tea leaves wrapped in plastic bags are placed on the placing tray, and the placing tray is transported by an annular crawler conveyor belt to drive the tea leaves to move and bake the plastic bags on the tea leaves so that they shrink and fit tightly against the surface of the tea leaves. At this time, the rack is engaged with the tooth grooves on the surface of the placing tray. When the placing tray is transported, it rotates and drives the tea leaves to rotate, and when it is transported, it passes through the upper top frame below. The upper top frame lifts up the top block and the tea leaves to expose their bottom, so that the heating range of the plastic bag is more uniform, the fitting is more complete, and the bottom part in contact with the conveying component can also be effectively wrapped.

[0006] As a further solution of the utility model: damping is provided at the rotation point of the placement plate and the annular crawler conveyor belt to prevent the placement plate from rotating without being affected by external forces during transportation.

[0007] As a further solution of the present utility model: A fan blade located in the middle of the movement track of the annular tracked conveyor belt is rotatably connected to the inner cavity of the baking oven. The fan blade is driven by a motor to rotate to drive air circulation, which can effectively heat the whole plastic-sealed bag.

[0008] As a further solution of the present utility model: One side of the baking oven is communicated with a discharge conveyor belt. A baffle is fixedly connected at the connection between the baking oven and the discharge conveyor belt. An outlet is opened on one side of the baffle facing the discharge conveyor belt.

When in use, when the sealing door is closed, the right side abuts against the left side of the baffle. At this time, the push plate presses the baffle, driving the elastic airbag to compress and the return spring to contract. At this time, the elastic airbag is squeezed, and the gas enters the airbag ring through the communication pipeline. The airbag ring expands to seal the gap between the baffle and the sealing door. When the sealing door is opened, the baffle loses the extrusion on the push plate, and the return spring drives the elastic airbag to expand, and the airbag ring retracts. While being able to seal and keep warm, it does not affect the normal opening and closing of the sealing door, can effectively reduce the wear generated by the opening and closing of the sealing door, and can ensure a good sealing effect after long-term use.

[0012] 1. In the present utility model, the placement tray is conveyed by the annular tracked conveyor belt to drive the movement of the tea leaves, and the plastic-sealed bag on the tea leaves is baked to make it shrink and closely adhere to the surface of the tea leaves. At this time, the rack meshes with the tooth grooves on the surface of the placement tray. When the placement tray is conveyed, it rotates itself to drive the tea leaves to rotate, and when being conveyed, it passes through the upper support frame below. The upper support frame jacks up the top block, jacks up the tea leaves, so that the lower part is exposed, making the heat receiving range of the plastic-sealed bag more uniform, making its fitting more complete, and effectively wrapping the lower part in contact with the conveying component.

[0013] 2. In this utility model, when the sealing door is closed, the right side abuts against the left side of the baffle plate. At this time, the push plate presses the baffle plate, driving the elastic airbag to compress and the return spring to contract. At this time, the elastic airbag is squeezed, and the gas enters the airbag ring through the connecting pipeline. The airbag ring expands to seal the gap between the baffle plate and the sealing door. When the sealing door is opened, the baffle plate loses the extrusion on the push plate, and the return spring drives the elastic airbag to expand, and the airbag ring retracts. While being able to seal and keep warm, it does not affect the normal opening and closing of the sealing door, can effectively reduce the wear generated by the opening and closing of the sealing door, and can also ensure a good sealing effect after long-term use.
