Because the heating sheet with a larger area is adopted, the sealing area is large, the thickness of the garbage bag at the sealing position is thinner, and the heating temperature can be properly reduced, so that the high-temperature resistant requirement and the circuit requirement on the sealing base 21 are reduced, and the cost is effectively reduced.
Simultaneously, the heating plate has higher intensity and longer service life relative to the heating wire, and the stability and the reliability of the sealing and packaging device are further improved.
It should be noted that the blade 212 may be replaced by other available garbage bag cutting structures known in the art. Such as movable saw teeth, movable flywheels, movable grinding wheels, movable blades, and heating wires, among others. Specifically, a base through hole may be formed in the middle of the sealing base, and the saw teeth, the flywheel, the grinding wheel, or the blade having a small horizontal size may be installed at one end of the base through hole and may be moved to the other end along one end of the base through hole by being driven by a driving device. When the saw teeth, the flywheel, the grinding wheel or the blade move to the other end along one end of the through hole of the base, the garbage bag in contact with the saw teeth, the flywheel, the grinding wheel or the blade is cut off.
The driving of the saw teeth, the flywheel, the grinding wheel or the blade and the driving of the flywheel, the grinding wheel and the rotation belong to the conventional technical means in the field, and the technical scheme can be easily understood by a person skilled in the art and is realized by arranging a corresponding structure. For example, the flywheel is horizontally arranged, a driving rotating shaft of the flywheel is in transmission connection with a reduction gear of a driving motor through a transmission gear and a transmission belt, the bottom of the driving rotating shaft is rotatably installed on the bottom plate, the driving motor is also installed on the bottom plate, the bottom plate is driven by another driving device to enable the bottom plate to move to the other end along one end of the base through hole, so that the flywheel is driven to move to the other end from one end of the base through hole, and meanwhile, the garbage bag is cut off by the rapidly rotating flywheel.
When the garbage bag cutting structure is a heating wire, two tail ends of the heating wire are connected with a heating circuit.
Of course, adopt the blade to cut off the structure as disposal bag, and the cutting part of blade front end is followed the structure that the length direction of sealing the terminal surface extends, the structure is simplest, and the cost is the lowest, and the good reliability.
It should be noted that, as is easily understood by those skilled in the art, the heating sheet is made of conductive metal material, similar to the heating wire, and is connected to the heating circuit.
As will be readily understood by those skilled in the art, the heating circuit is communicably connected to a control device so as to control the heating sheet to heat up to the melting temperature of the garbage bag when sealing is performed, and not to heat up when sealing is not required. This is a conventional technique.
Preferably, as shown in fig. 4, the end surface 41 of the pressing rod has a pressing rod groove 411 or a pressing rod through hole, the pressing rod groove 411 or the pressing rod through hole matches with the edge of the blade 212, and the pressing rod groove 411 or the pressing rod through hole and the blade cooperate to cut off the garbage bag, so as to form a new bag bottom and a new bag opening.
Preferably, the pressing rod 40 can be an integrated structure, and the pressing rod end surface 41 is provided with a pressing rod groove or a pressing rod through hole; or
The pressing rod is of a split structure and comprises an upper pressing rod and a lower pressing rod, and a pressing rod through hole is formed between the upper pressing rod and the lower pressing rod.
It should be noted that the function of the pressing bar groove 411 is to provide a certain space for the garbage bag cutting structure (preferably, the blade portion of the blade), so that when the garbage bag is sealed by the sealing end face, the blade portion of the blade can enter the pressing bar groove 411 and cut off the garbage bag. As will be readily understood by those skilled in the art, the strut groove may also be a strut through hole.
Preferably, as shown in fig. 5, in the orthographic projection view, the blade portion of the blade 212 is inclined from one end to the other end so that when the pressing rod end surface 41 contacts the sealing end surface 211 for sealing, one end of the blade portion is first cut off by contacting the garbage bag, and the other end is then cut off by contacting the garbage bag.
The cutting part of the blade is obliquely arranged, so that the pressure intensity in the process of cutting the garbage bag can be improved, the thrust required for cutting off the garbage bag is greatly reduced, the garbage bag is easier to cut off, the cutting reliability is improved, and the garbage bag can be effectively cut off completely.
