Sanitary towel package sealing machine and sealing method
Technical field
The present invention relates to a kind of sanitary towel package sealing machine and sealing method that the sanitary towel package full automaticity seals that be used for, belong to package sealing machine and make the field.
Background technology
CN2778697 Y, title " Sealing bodies of plastic packaging machine ", including heat melts on the chip shape, lower cutter and with last, the open-close type driver train that lower cutter links together, open-close type driver train among the design is by the base plate that is fixed on the plastic sealing pack machine frame, be vertically located in the guide pillar on the base plate, be sleeved on the guide pillar and be slip cooperating relationship on, bottom guide, by tapped through hole and last, the screw rod that bottom guide is assembled together with positive and negative two sections screw threads, and form with the direct-connected drive motor of screw rod, on, extended cantilever and last on the bottom guide, lower cutter is fixed together.Its weak point: the full-automation that can't be applicable to sanitary towel package is sealed.
Summary of the invention
Design goal: the weak point of avoiding background technology to exist, design a kind of can enforcement entirely from sanitary towel package sealing machine and the sealing method of changing packing packaged sanitary napkin.
Design plan: in order to realize above-mentioned design goal.1, the packaging bag passage is positioned on the frame work top and the packaging bag passage has the criss-cross groove and adopts the propulsion source of Rodless cylinder as the sanitary towel package propulsive mechanism, is one of feature of the present invention.The purpose of doing like this is: because Rodless cylinder can advance in the straight trough in the criss-cross groove of packaging bag passage and reset apace, and can accurately move to the position of its setting along its guide rail, therefore adopt the propulsion source of Rodless cylinder as the sanitary towel package propulsive mechanism, the packaging bag that can guarantee to be equipped with sanitary napkin can be advanced to the position of its setting quickly and accurately along road packaging bag passage.2, descending cylinder lower end be provided with hot melt pressure head and cutting knife and with the design that the base plate of the up cylinder piston end face of up cylinder operation mechanism that is arranged in frame work top below is complementary, be two of feature of the present invention.The purpose of doing like this is: the hot melt pressure head of descending cylinder piston end and cutting knife match with the base plate of up cylinder piston end, can make the sack of therebetween sanitary towel package extrusion bonded, be cut off, thereby realize the purpose that quick heat sealing, unnecessary waste material cut off by cutting knife and base plate relativity by hot melt pressure head and base plate.3, the setting of pneumatic turning mechanism is three of a feature of the present invention.The purpose of doing like this is: because the limb shape of the limb adapter plate in this pneumatic turning mechanism is triangular in shape, when by the sanitary towel package that sealed by the exhaust of pneumatic exhaust stop gear pressing plate, positioning plate spacing after, its limb adapter plate that is positioned at the sanitary towel package both sides is inserted into the required groove that seals in drive following moment of duplex cylinder with sanitary towel package.4, the design of pneumatic exhaust stop gear is four of a feature of the present invention.The purpose of doing like this is: when sealing owing to sanitary towel package, must be with the air exhaustion in the bag, can guarantee rectangular bag shape after sanitary towel package seals, otherwise, the bag shape of the sanitary towel package after sealing is with angry capsule situation, can't enter in the packing chest and pack, also can't neatly stack.Therefore, with the air exhaustion in the sanitary towel package, can make the air in the sanitary towel package after sealing reduce to minimum, the shape invariance shape of the sanitary towel package after guaranteeing to seal by pneumatic pressing plate and the pressing plate of pressing down.5, the design of pneumatic exhaustion mechanism is five of a feature of the present invention.The purpose of doing like this is: since in the pneumatic exhaustion mechanism pull bar cylinder have simple in structure, reciprocating speed is fast, the therefore handle that drives by the pull bar cylinder, enough sanitary towel packages after will sealing are apace pulled out the passage after packaging bag.
Technical scheme 1: sanitary towel package sealing machine, it comprises frame, gas circuit and control setup, the packaging bag passage is positioned on the frame work top and the packaging bag passage has the criss-cross groove, the Rodless cylinder propulsive mechanism be positioned on the frame and Rodless cylinder anterior to drive push pedal reciprocating along the criss-cross groove, door frame and descending cylinder lower end that descending cylinder operation mechanism is positioned at the cross recess top are provided with hot melt pressure head and cutting knife, work top below and up cylinder piston end face that relative with descending cylinder operation mechanism up cylinder operation mechanism is positioned at frame are equipped with base plate, the end face that pneumatic turning mechanism is positioned at cross recess both sides and two cylinder pistons is equipped with the limb adapter plate, pneumatic exhaust stop gear is positioned on the frame and is positioned at the top of packing passage, and pneumatic exhaustion mechanism is positioned on the frame of packing channel rear portion.
Technical scheme 2: the sealing method of sanitary towel package sealing machine, sanitary towel package after the pack is pushed in the seal package structure by push pedal in the Rodless cylinder pushing mechanism, the up cylinder of pressing plate and up cylinder operation mechanism that is arranged in the pneumatic exhaust stop gear of packaging bag top drives and moves common air exhaustion with packaging bag on the base plate, spacing duplex cylinder drive positioning plate moves down spacing in the pneumatic exhaust stop gear, two duplex cylinders drive respectively that two limb adapter plates are two-way to be inserted to the packaging bag both sides in the pneumatic turning mechanism 11, make packaging bag both sides concavity, descending cylinder drives that the hot melt pressure head presses down and with plastic packaging bag sack hot melt leak free simultaneously in this moment descending cylinder operation mechanism, the unnecessary part of packaging bag sack that the duplex cylinder will drive after cutting knife will seal is cut away, hot melt pressure head and cutting knife are up under descending cylinder drives, the waste material that is cut off is inhaled useless mouth negative suction pipeline and is transported in the collection box, two duplex cylinders drive two limb adapter plates respectively and reset in the pneumatic turning mechanism 11, this moment, spacing duplex cylinder drove horizontal reset on the positioning plate, and the pull-out assembly in the pneumatic exhaustion mechanism is pulled out by the packaging bag that handle will seal.
The present invention compares with background technology, and the one, not only realize the automation of closing that sanitary towel package seals, and realized sealing the automatic recovery of back waste material; The 2nd, structure design novelty, uniqueness, simple, stable work in work, reliable; The 3rd, environmental protection, pollution-free, energy consumption is low.
