[0002] Continuous plastic film sealing machines are widely used in packaging for industries such as food, pharmaceuticals, daily chemicals, agricultural products, fertilizers, and clothing. Their working principle is as follows: the plastic packaging bag is driven by a bag conveyor belt, which feeds the sealed portion of the bag into a running film bag opening heat-sealing clamping conveyor belt mechanism. The bag is then heated and sealed before being conveyed out. Compared to traditional manual sealing operations, this significantly improves sealing efficiency and quality.

[0003] A search revealed Chinese patent publication number CN218023973U, which discloses a continuous sealing machine for plastic film of traditional Chinese medicine decoction pieces. The machine features a telescopic rod bolted to the upper end of a heat insulation plate, with a cylinder connected to the upper end of the telescopic rod. A photoelectric sensor is positioned between the right-angle plate and the lower heating block, and the sensor is fixed to the front shell of the machine body with screws. This design addresses the problems of existing continuous sealing machines for plastic film, such as the lack of scalding protection on the outside of the heating block and the simple structure of the cooling block leading to poor heat dissipation. However, the aforementioned patent for a continuous sealing machine for plastic film of traditional Chinese medicine decoction pieces has the following shortcomings: During use, the product is conveyed after heat sealing, but it is prone to detachment during transport, causing the product to fall out of the plastic package during use, resulting in inconvenience. Furthermore, the packaged product cannot be easily collected, leading to collection difficulties during use. Utility Model Content
