Pocket seals outspoken fast cooling mechanism
(1) technical field
What the present invention relates to is a kind of cooling mechanism, specifically a kind of cooling mechanism that is used for package packing machine.
(2) background technology
Adopting monofilm or complex film at present is the heat-sealing mouth wrapping machine of packing, if seal refrigerating function, adopt compressor formula air conditioner cooling system without exception, the technology of this system own is ripe, but its component units is more, complex structure, and volume is big, relatively poor with the associativity of wrapping machine, operation and maintenance cost are higher; Compressor formula air conditioner cooling system has a fatal shortcoming in addition, and system's dichlorodifluromethane is a cooling media, and the dichlorodifluromethane material has destructive effect to ozone layer, has begun progressively to ban use of the dichlorodifluromethane material in the world.
(3) summary of the invention
The object of the present invention is to provide a kind of reliability that cools off rapidly, can improve pocket heat-sealing mouth, the pocket that reduces bag opened rate seals outspoken fast cooling mechanism.
The object of the present invention is achieved like this: it comprises the suspension bracket that is installed on the bag forming automatic packaging machine frame, suspension bracket is made up of horizontal segment and vertical section, vertical section bottom at suspension bracket is provided with installation base plate, fixedly an airduct and a movable airduct respectively are set in the both sides of installation base plate, have air outlet on the fixed and movable airduct, fixedly airduct is fixed on the installation base plate, rotating shaft is installed on installation base plate, movable airduct is installed in the rotating shaft, pivoted arm is installed in the rotating shaft, cylinder is installed on the installation base plate, the piston rod of cylinder links to each other with pivoted arm, the eddy current cooling vessel is installed in the vertical section of suspension bracket, and the eddy current cooling vessel links to each other with fixing airduct with movable by blast pipe.
The present invention is one of important component part of bag forming automatic packaging machine.After pocket behind the heat sealing is sent to and seals the cooling station, cylinder by pivoted arm and rotating shaft drive activity cool air hose to lower swing, pocket sack heat seal position is clamped, the low-temperature airflow that the eddy current cooling vessel is produced by boasting directly cools to heat seal portion, the cooling exhaust hood is by pivoted arm and the counter motion of rotating shaft drive activity cool air hose, unclamp pocket, finish a working cycle, a pocket is successively through twice cooling.Device of the present invention utilizes the eddy current cooling principle, the pocket of the cold wind air-flow that produces below 0 ℃ (minimum reaching-40 ℃ below) with instrument wind after to heat-sealing seals and carries out front and back twice and cool off, the cold wind that vortex tube produces props up to connect to blow to and seals, effectiveness of regenerator is high and reliable like this, pocket sealed also and can in time cool off when assurance ambient temperature height and package speed were fast, had guaranteed the reliability that seals.Power consumption in service is little, and system does not have dichlorodifluromethane material, environmentally safe.Device of the present invention can be reduced to solidification temperature with the heat-sealing mouth of pocket from the melt temperature of pocket at short notice, improves the reliability of pocket heat-sealing mouth, reduces bag opened rate.
