[0002] With the development of the tea industry, automated tea bag production has become increasingly diverse. Most of the existing automated tea bag packaging equipment uses a robotic arm to assist in feeding tea bags into the packaging bags. Among them, it also involves mechanisms to separate stacks of packaging bags one by one and open the packaging bags, with too many steps and low production efficiency. Summary of the Invention

[0003] An object of the present invention is to solve at least one of the technical problems existing in the prior art, and to provide a tea bag packaging machine that can encapsulate tea bags into the packaging while producing the outer packaging of tea bags alone, thereby improving production efficiency.

[0004] The tea bag packaging machine according to the first aspect embodiment of the present invention includes:

[0005] A tea bag feeding mechanism for feeding tea bags, including a conveyor belt and a feeding channel, and the conveyor belt is arranged in the feeding channel;

[0006] A guide cylinder is vertically arranged below the discharge end of the tea bag feeding mechanism, and the upper end of the guide cylinder is in a funnel shape;

[0007] A winding part is arranged on the upper part of the guide cylinder for winding the packaging tape into a cylinder and wrapping it around the outside of the guide cylinder;

[0008] A pushing mechanism is arranged above the upper opening of the guide cylinder for pushing the tea bag into the guide cylinder;

[0009] A loading device is arranged above the guide cylinder for placing a whole roll of packaging tape;

[0010] A feeding mechanism is arranged between the guide cylinder and the loading device, including a driving roller and a plurality of driving rollers, and the feeding mechanism is used to send the packaging tape to the winding part;

[0011] A first plastic sealing machine is longitudinally arranged on one side of the guide cylinder for plastic-sealing the side edges of the packaging;

[0012] A driving wheel is arranged below the first plastic sealing machine for driving the packaging tape to move downward;

[0013] A second plastic sealing machine is arranged below the guide cylinder for plastic-sealing the upper and lower sides of the packaging, and a blade is arranged at the crimping part of the second plastic sealing machine.

[0014] The tea bag packaging machine according to the embodiments of the present invention has at least the following technical effects: The roll of packaging tape is installed on the loading device. The packaging tape is pulled out from the loading device, extends into the feeding mechanism, passes through the gap between the driving roller and a transmission roller, and then bypasses several other transmission rollers. The packaging tape is tightly pulled to the winding part and wound into a cylinder under the action of the winding part and wrapped around the outside of the guiding cylinder. The two side edges of the wound packaging tape are attached and pass through the first plastic sealing machine for side plastic sealing. The side edges of the plastic-sealed cylindrical packaging tape pass through the driving wheel and move downward under the action of the driving wheel. The bottom of the cylindrical packaging tape extends into the second plastic sealing machine for upper and / or lower edge plastic sealing. The tea bags are sent above the guiding cylinder by the tea bag feeding mechanism and fall into the opening of the guiding cylinder. At this time, the pushing mechanism works to push the tea bags into the guiding cylinder. After the tea bags fall through the guiding cylinder into the bottom of the cylindrical packaging tape that has completed side and lower edge plastic sealing, the driving wheel drives the cylindrical packaging tape to move downward, and the second plastic sealing machine performs upper edge plastic sealing and cutting to complete the packaging of the tea bags. The packaging bag of the tea bag is directly made from the roll of packaging tape. When a packaging bag is completed, the tea bag is also packaged into the packaging bag at the same time. A single machine can complete this process without pre-making the packaging bag. The process is simple and the tea bag packaging efficiency is high.

[0015] According to some embodiments of the present invention, the tea bag feeding mechanism is further provided with a tea bag tray for loading single tea bags. The tea bag tray is arranged on the conveyor belt, and the tea bag tray is provided with an opening facing the advancing direction of the conveyor belt. The tea bag tray for accommodating single tea bags is used to transport the tea bags, ensuring that the tea bag feeding mechanism drops only one tea bag each time, preventing mistakes such as packaging two or more tea bags in a single package.

[0016] According to some embodiments of the present invention, the tea bag feeding mechanism is further provided with a transparent cover plate, and the cover plate covers the feeding channel. The cover plate is provided to prevent dust or other impurities from falling into the tea bag during transportation. The transparent cover plate facilitates observing the tea bag feeding mechanism at any time.

[0017] According to some embodiments of the present invention, one side of the cover plate is movably connected to one side of the feeding channel. The cover plate is hinged to the feeding channel, and the cover plate can be opened and closed. When there are problems in the tea bag feeding mechanism, the cover plate can be opened to quickly operate on the tea bag feeding machine.

[0018] According to some embodiments of the present invention, the feeding mechanism is provided with hollow strips, and both ends of the transmission roller are movably arranged in the hollow strips. The part where the transmission roller is movably arranged in the hollow strips can be adjusted in position as needed.

[0019] According to some embodiments of the present invention, a baffle is provided above the material guiding cylinder, and an extension plate is provided on one side of the opening of the material guiding cylinder facing the tea bag feeding mechanism, and the extension plate is attached to the opening of the material guiding cylinder. The baffle can prevent the tea bags from flying out from above the material guiding cylinder, and the extension plate can prevent the tea bags from falling from the gap between the material guiding cylinder and the tea bag feeding mechanism.

[0020] According to some embodiments of the present invention, the pushing mechanism is provided with a driving device and a pushing head, and the driving device is used to drive the pushing head to move up and down; the diameter of the pushing head is smaller than the inner diameter of the material guiding cylinder. When the tea bag stops at the opening of the material guiding cylinder and cannot fall, the pushing head presses down to push the tea bag into the material guiding cylinder, preventing the tea bag from staying at the material guiding cylinder.

[0021] According to some embodiments of the present invention, a chamfer is provided at the bottom of the pushing head, and the pushing head is made of plastic. The design of the chamfer can remove the sharp edges, and the plastic material has a lower hardness, thus avoiding damage to the tea bag by the pushing head.
