Description
Technical field
The utility model is related to packing machine field more particularly to a kind of automatic quantitative packings that can securely clamp packaging bag
Machine.
Background technology
Automatic quantitative packing machine, is that one kind is controlled by computer, and collection digital quantitative weighs, is packaged in integrated packaging facilities.
Scale hooper is added by feeder (pneumatic gate valve) in material, after controller receives the weight signal of sensor, by preset
Programmed value is controlled, carry out when beginning quickly (it is fast plus, in plus, it is slow plus simultaneously) feed；When weight >=(desired value-slightly metering
Value) when, stop the output of fast plus signal, into middling speed (in plus, slow plus simultaneously) feed；When weight >=(desired value-essence variable)
When, plus signal exports in stopping, into (slow to add) feed at a slow speed；When weight >=(desired value-overshoot magnitude), stop slow plus letter
Number output, feeding gate completely closes, and definite value, which weighs, to be completed.After the input of folder bag signal, scale hooper Dump gate automatically turns on, and works as weight
When≤zero position set point, scale hooper Dump gate is automatically closed, and material bag unclamps automatically to be fallen on conveyer belt, and sack closer seam is sent to
Enter subsequent processing after packet, while controller enters next control loop.
It is a kind of with self-cleaning function that number of patent application is that the utility model patent of CN201120481237.8 discloses
The filling discharging bag-clamping mechanism of automatic quantitative packing machine, belongs to packing machinery technology.Full-automatic quantitative packing machine includes machine
Frame, is installed with positioning disk in rack, and the center of positioning disk constitutes feed pipe sleeve of weighing, the center for feed pipe sleeve of weighing
It is configured to pan feeding chamber；Material storage mechanism；Weighing mechanism；Weigh feed pipe, the upper end and feed pipe sleeve connection of weighing, lower end with claim
Heavy-duty machine structure connects；A pair is weighed feed pipe clamp system；It weighs and expects discharging mechanism；Material compensation mechanism, filling discharging bag inserting machine
Structure includes filling discharging bag-clamping mechanism ontology comprising device is clamped in picking-up container and a pair of of packing bag mouth, is characterized in that wrapping
It packs and offers dust exhausting hole on the wall body of sack casing, dust flue, dust flue and negative pressure dust removing device are connected on dust exhausting hole
Connection.Advantage：Can the dedusting under non-stop-machine state, it is not necessary that by worker's manual operations, packaging efficiency is high, labor intensity
It is low.
Above-mentioned bag-clamping mechanism is substantially still drawn over to one's side two clamp arm using cylinder, to clamp the bag on discharge nozzle.
When cylinder movement, clamp arm is verted and is clamped the bag.But the pinch in clamp arm can only be contacted with packaging bag line, and the contact line
Clamping effect for level curve, pinch is poor, and packaging bag is easy to slide after being packed into more material.Due to the elongation of cylinder
It is not easy to accurately control, and the thickness of packaging bag is not easy, then in most cases can all occur can only line between pinch and packaging bag
The case where contact, packaging bag it is larger can not to fall probability by reliable grip.Enable in packaging bag reliable grip to discharge nozzle,
It must make that forming face contacts between clamp system and packaging bag or the line of vertical direction contacts.
