The cooling hole-punching method of a kind of infusion bag of the present invention, is specially:
1) on upper cold plates, lower cold plates, the position corresponding with the non-welding region of bag body arranges the perforate of given shape;
2) at tapping, vacuum cup is set and drives bagging apparatus;
3) when upper cold plates, lower cold plates are pushed down bag and are carried out cooling punching, vacuum cup is driven bagging apparatus the two-layer co-extrusion film of non-welding region is pulled open mutually, make upper and lower two-layer co-extrusion film remain on the state of a relative separation, after punching completes, vacuum fails co-extrusion film is unclamped, and bag is circulated to follow-up station.
Step 2) in perforate be according to the non-welding region of bag body size and at bag position with it, the perforate arranging in upper cold plates, the corresponding position of lower cold plates, in the time that upper cold plates, lower cold plates are pushed down bag, the region of perforate matches with a bag body non-welding region, and the co-extrusion film in this part region plate that is not cooled is pushed down.
Vacuum cup is installed at fluting place and is driven bagging apparatus, refer on the cold plates of fluting place and a contact bag relative side sucker cylinder is installed, cylinder rod, through cold plates, is fixed vacuum cup by being connected and fixed bar at the front end of cylinder rod, makes vacuum cup be positioned at the area of space of fluting.
When upper cold plates, lower cold plates are pushed down bag to carry out cooling punching, vacuum cup is opened bag assembly effect the co-extrusion film of non-welding region is withstood and pulled open, but the very little upper and lower two membranes of the distance of pulling open remains on the state of a relative separation, after punching completes, vacuum fails film is unclamped, cylinder action resets, and bag is circulated to follow-up station.Its concrete algorithm refers to that the bag after hot synthetic type is sent to cooling punching station, cold plates moves up and down cylinder and moves upper cold plates, lower cold plates is pushed down bag, the action of punching cylinder drives the punching head that the firm front end of punching cylinder is installed to carry out punching to bag, when bag is pushed down in cold plates action, be arranged on, vacuum cup is withstood on bag body fill type bag body of infusion bag the not co-extrusion film of welding region by bag cylinder action of opening on lower cold plates, action of vacuum sucker holds the co-extrusion film in this region from upper and lower both sides, opening bag cylinder again moves film is pulled open to the distance very little to, make co-extrusion film state in film layering in cooling punching of non-welding region, after punching completes, vacuum fails film is unclamped, cylinder action resets, bag is circulated to follow-up station.
As shown in Figures 1 to 5, the cooling hole punched device of a kind of infusion bag of the present invention, comprises that cold plates moves up and down cylinder 1, upper cold plates 3, lower cold plates 4, opens bag cylinder 5, punching cylinder 6, punching head 7, vacuum cup 10, pipe link 14.The cold plates that is provided with its motion of control on upper cold plates 3 and lower cold plates 4 moves up and down cylinder 1.Opening bag cylinder 5, pipe link 14, vacuum cup 10 entirety forms vacuum cups and drives bagging apparatus.
According to tail fill with the reserved bag body afterbody of formula infusion bag 2 afterbodys not weld zone 12 size, position with it of bag and on cold plates 3,2 bags of bodies of lower cold plates 4 and tail filling formula infusion bag situation about contacting, in upper cold plates 3, the corresponding position of lower cold plates 4, square fluting 11 is set, the region of square fluting 11 does not match weld zone 12 with bag body afterbody, and the co-extrusion film in this part region is not pushed down by upper cold plates 3, lower cold plates 4.
On upper cold plates 3, lower cold plates 4, the corresponding position of square fluting 11 is all installed with out bag cylinder 5, opening bag cylinder 5 pipe links runs through by the first group of manhole arranging on upper cold plates 3, lower cold plates 4, vacuum cup 10 is fixed on out the front end of bag cylinder 5 pipe links, and the vacuum cup 10 fixing is positioned at the area of space of square fluting 11.Open bag cylinder 5 and drive pipe link, control vacuum cup 10 up-and-down movement in the area of space of square fluting 11.Vacuum cup 10 can hold the co-extrusion film in this region from upper and lower both sides, and upper layer film 8 and the lower membrane 9 of weld zone 12 do not keep the state of film layering in the time of cooling punching to make bag body afterbody.
On upper cold plates 3, be also provided with support 15, be provided with punching cylinder 6 on support 15, the front end of punching cylinder 6 is provided with punching head 7.Punching head 7 is corresponding to the location hanging hole 13 of infusion bag afterbody.On upper cold plates 3, be provided with second group of manhole, punching head 7 runs through by second group of manhole.
Concrete workflow: the tail after hot synthetic type is filled with formula infusion bag 2 and is sent to cooling punching station, cold plates moves up and down cylinder 1 action by upper cold plates 3, lower cold plates 4 is pushed down tail filling formula infusion bag 2 bags and is carried out cooling, 6 actions of punching cylinder drive the punching head 7 that is arranged on its front end to carry out die-cut location hanging hole 13 to tail filling formula infusion bag 2, at upper cold plates 3, when bag is pushed down in lower cold plates 4 actions, bag cylinder 5 of opening being arranged on cold plates 3 and lower cold plates 4 moves vacuum cup 10 is withstood on bag to the not co-extrusion film of weld zone 12 of bag body afterbody, action of vacuum vacuum cup 10 holds the co-extrusion film in this region from upper and lower both sides, opening bag cylinder 5 again moves film is pulled open to the distance very little to, make not upper layer film 8 and lower membrane 9 state in film layering in cooling punching of weld zone 12 of bag body afterbody.
The beneficial effect that the present invention has: by fluting being set in the specific position of cold plates, the reserved not co-extrusion film of welding region as liquid medicine filling mouth on bag body fill type bag body of infusion bag in the time that pushing down bag, cold plates is not held down, the vacuum open bag sucker device that is simultaneously arranged on fluting place can make the reserved not co-extrusion film state in layering in the time carrying out cooling punching of welding region as liquid medicine filling mouth on bag body fill type bag body of infusion bag, thereby guarantee can again not be sticked together as the reserved not co-extrusion film of welding region of liquid medicine filling mouth, for the follow-up filling bag pretreatment that carried out opening, improve the filling bag efficiency of opening, reduce cost, improve benefit.
