Description
Technical field
The utility model relates to packing machinery technology, particularly a kind of heat-sealing head reciprocator.
Background technology
Heat-sealing bag is generally applied in the fields such as daily chemical products packaging, food and medicine packaging.Heat Sealing heats sealing part material by some way, and after making it reach viscosity flow state, pressurization makes it seal, generally completes with hot-press sealed device or heat sealing machine.Heat-sealing head is the actuating unit of Heat Sealing, according to the version of heat-sealing head and the difference of method of heating, the method for hot-press sealed can be divided into: ordinary hot press seal is legal, fusing involution, pulse involution, ultrasonic sealing function, high-frequency heat sealing and induction heat involution is several.Ordinary hot press seal is legal is current most popular heat-sealable way because it to have its efficiency high, the advantages such as equipment price is low.The legal crank motion by heat-sealing head of ordinary hot press seal, realizes the continuous sealing operation of packaging bag.Common heat-sealing head is connected to cylinder, and drive heat-sealing head to move back and forth by cylinder, its cost is larger, and in motion process, its reciprocating speed is identical, because in upward stroke, heat-sealing head will control in lower speed, so cause its work efficiency lower, cost is higher.
Utility model content
The purpose of this utility model is to provide a kind of heat-sealing head reciprocator, realizes heat-sealing head upward stroke medium velocity comparatively slow, and ensure heat-sealing effect, decline process medium velocity is very fast, increases work efficiency.
The utility model solves the technical scheme that its technical matters adopts:
A kind of heat-sealing head reciprocator, comprise support platform, heat-sealing head, upper mounting plate, driven shaft, driven shaft sleeve, lever, extension spring, lever support, electromagnet, damper, needle-valve, described upper mounting plate and support platform be arranged in parallel up and down, the driven shaft sleeve of vertical direction is fixed with between described upper mounting plate and support platform, described driven shaft concentric and can slide up and down and be arranged in driven shaft sleeve, the upper end of described driven shaft is provided with heat-sealing head, the side of described driven shaft is provided with spacing touching block, the upper end of described spacing touching block is provided with upper stroke switch, the lower end of described spacing touching block is provided with lower stroke switch, described upper stroke switch is all connected electromagnet with lower stroke switch, described electromagnet comprises fixed bearing and movable core, described fixed bearing is fixed on upper mounting plate, described movable core is bar-shaped, and in being vertically arranged in fixed bearing, between the movable core that described lever support is arranged on and driven shaft, the centre of described lever is hinged on lever support, the left end of described lever is hinged on movable core, the right-hand member of described lever is hinged on driven shaft, described extension spring and driven shaft are in the same side, described extension spring one end is connected on upper mounting plate, the other end is connected on lever, described damper is immediately below electromagnet, on described movable core, concentric is fixed with piston ring, described piston ring can slide up and down and be arranged in damper, and damper is divided into upper cavity and lower chamber, the lower end of described movable core is also provided with air channel, the two ends of air channel are positioned at the top and bottom of piston ring, the lower end of described air channel connects needle-valve, described piston ring is provided with the check valve can only ventilated from upper cavity toward lower chamber.
Further, O shape is had to enclose between described damper and movable core.
Compared to the prior art the utility model, has the following advantages and effect: upper stroke switch and lower stroke switch control the power on/off of electromagnet.There is O shape to enclose between damper and movable core, ensure that damper good seal, prevent air from passing in and out damper.Driven shaft is upward movement under the effect of extension spring, the movable core of electromagnet moves downward, because the air in the lower chamber of damper can only enter upper cavity through needle-valve and air channel, therefore form damping and make driven shaft drive heat-sealing head upward movement with lower speed.When the spacing touching block on driven shaft touches upper stroke switch, electromagnet is energized, movable core upward movement, because the air of the now upper cavity of damper enters lower chamber rapidly by check valve, therefore driven shaft can move downward with speed faster under the effect of lever.It is comparatively slow that the utility model effectively realizes heat-sealing head upward stroke medium velocity, and ensure heat-sealing effect, decline process medium velocity is very fast, increases work efficiency.
