[0032] Compared with the prior art, the present invention has the following beneficial effects:

[0033] 1) This invention first transports an empty clamping fixture to the bag-loading device station via a turntable mechanism. The bag-loading device separates the packaging bags one by one and places them on the clamping fixture, clamping the ends of the bags. The turntable mechanism then continues to rotate, transporting the bags to the tea cake feeding device station. The tea cake feeding device opens the other end of the packaging bag, inserts the positioned tea cake into the bag, and pushes it inside. Next, the bags are transported to the heat-sealing device station, where they are pre-pressed and positioned before being heat-sealed, completing the packaging of the tea cakes. Finally, the bags are transported by the turntable mechanism to the unloading device station. At this point, the turntable mechanism opens and blows air to collect the packaged tea cakes. By adopting the above technical solution, this invention achieves automatic bag feeding, automatic tea cake feeding, automatic bag opening / pushing, heat sealing, and automated unloading throughout the entire packaging process, enabling a continuous process for the entire tea cake production. The overall automation level is high, and the production efficiency can reach up to 5600 PCS / H. It effectively reduces labor costs and labor intensity, resulting in low production costs, high product quality, high yield, and high equipment utilization.

[0034] 2) It achieves fully automated integrated packaging of tea cakes, with high production efficiency, effectively saving manpower and time, and ensuring a safe and hygienic production process. The arrangement of the bag-loading device, tea cake feeding device, heat-sealing device, and unloading device along the circumference of the rotating turntable mechanism ensures that each mechanism is independent yet interconnected, preventing interference between them. This results in a reasonable and simple structural design, easy operation, and produces exquisite and beautiful tea cake packaging, extending shelf life. Furthermore, if any functional block is damaged, only the damaged block needs to be replaced, making maintenance convenient.

[0035] 3) After the tea cake is in place, the third drive source drives the clamping and positioning component to clamp and position the fed tea cake. Then, the first drive source drives the clamping and positioning component to insert into the opened packaging bag. Finally, after the tea cake positioned on the clamping and positioning component is quickly pushed away from the clamping and positioning component and into the packaging bag by the second drive source, the first drive source drives the clamping and positioning component to reverse its operation, completing one feeding cycle. The above design has the advantages of reasonable structure, simple operation, smooth operation and labor saving. Moreover, bidirectional feeding further improves packaging efficiency.

[0036] 4) The present invention provides a pressing component between the first clamping arm and the second clamping arm, and the pressing component is swayably mounted on the clamping positioning bracket for vertical positioning of the tea cake, so that the tea cake is always positioned in a triangular shape during the entire pushing process, effectively avoiding displacement or flipping during movement, and further improving the packaging effect.

[0048] Please see the appendix Figures 1 to 8As shown: A tea cake packaging machine includes a frame 1 and a turntable mechanism 2 rotatably mounted on the frame 1. A bag-loading device 3, a tea cake feeding device 4, a heat-sealing device 5, and a discharge device 6 are sequentially arranged along the circumference of the turntable mechanism 2. The frame 1 is a common rectangular frame structure with sheet metal outer covering and casters at the bottom. The frame 1 is equipped with a PLC controller for controlling the operation of the tea cake packaging machine. The automation control part of this device can be specifically set by those skilled in the art according to the requirements of the tea cake packaging process, the structure and working process of the tea cake packaging machine described below, and will not be elaborated here. The turntable mechanism 2 is used to carry the packaging bags so that they pass through the tea cake feeding device 4, the heat sealing device 5 and the unloading device 6 in sequence to complete the packaging. The bag feeding device 3 is used to separate the stacked packaging bags one by one and place them on the turntable mechanism 2 for clamping. The tea cake feeding device 4 is used to position the tea cakes and insert them into the packaging bags one by one and push them into the packaging belt to complete the tea cake bag entry. The heat sealing device 5 is used to pre-press and shape the packaging bags containing tea cakes and then perform the final heat sealing. The unloading device 6 is used to automatically unload the finished products. In this embodiment, through the coordinated operation of the turntable mechanism 2, the bag-loading device 3, the tea cake feeding device 4, the heat-sealing device 5, the unloading device 6, and the PLC controller, automatic bag feeding, automatic bag opening, automatic tea cake alignment and feeding, automatic bag heat sealing, and automatic finished product unloading are achieved. This effectively ensures production quality and features a reasonable structural design, cost savings, high work efficiency, reduced labor costs and labor intensity, low production costs, good product quality, high yield, and high equipment utilization.

[0049] Based on the above embodiments, the tea cake feeding device 4 includes: a tea cake conveying component 41, a bag opening component 42, and a tea cake feeding component 43. Specifically: the tea cake conveying component 41 is mirror-mounted on the top of the frame 1, used to connect to externally input packaged tea cakes, correct and position them before pushing them onto the tea cake feeding component 43; the bag opening component 42 is fixed to one side of the tea cake conveying component 41, used to open the packaging bags on the turntable mechanism 2, facilitating the quick and accurate insertion of the tea cake feeding component 43 into the packaging bags; the tea cake feeding component 43 is slidably disposed between adjacent tea cake conveying components 41, used to connect to the tea cakes from the tea cake conveying component 41, correct and position them, insert them into the packaging bags, and then push them into the packaging bags. In this embodiment: the opening component 42 uses vacuum adsorption to clamp the upper and lower films of the packaging bag, then moves them in opposite directions to open the bag. Simultaneously, the tea cake conveying component 41 pushes the pre-positioned tea cake into the tea cake feeding component 43, which then clamps and positions it again before inserting it into the packaging bag. Finally, the tea cake is pushed into the packaging bag by the tea cake feeding component 43 and then removed. In this embodiment, the bag component 42 opens the bag to provide sufficient space; then the tea cake conveying component 41 pushes the pre-positioned tea cakes one by one into the tea cake feeding component 43, which then inserts the pre-positioned tea cakes, along with itself, into the opened packaging bag. Finally, the tea cake is pushed into the packaging bag by the tea cake feeding component 43, completing one feeding operation. The above design can effectively reduce the space occupied by the equipment, thereby improving work efficiency and further improving the packaging efficiency of tea cakes. In addition, by inserting the tea cake together with the tea cake feeding component 43 into the open packaging bag, it can effectively avoid the tea cake shifting during the pushing process, which would cause uneven local force when entering the bag and damage to the packaging bag during the pushing process, thus further improving the packaging quality.

In this design: when the tea cake is in place, the third drive source 435 drives the clamping and positioning component 436 to clamp and position the fed tea cake. Then, the first drive source 431 drives the clamping and positioning component 436 to insert into the opened packaging bag. Finally, the second drive source 433 drives the pushing component 434 to quickly push the tea cake positioned on the clamping and positioning component 436 away from the clamping and positioning component 436 and into the packaging bag. After that, the first drive source 431 drives the clamping and positioning component 436 to reverse its operation, completing one feeding cycle.
