Multiple Infeed Lanes
The wraping system emerged with multiple infeed lanes to guide bottles into the correct one with smart sensors. With the high automatic wrapper, you can integrate the wrap process into your Steplead PacTek filling line to shrink-wrapping different kinds of products.
Control System
Moreover, the infeed tunnels integrated intelligent sensor helps to tell the presence or absence of products. By sending signals to upstream to regulate the conveyor speed when it detects too many
When detecting many products infeeding, by sending signals to upstream to regulate the conveyor speed, it will assure a smooth flowing for the wrapping process. Conversely, if no products detected at all, it will stop the wrap machine automatically, only restarts it once new batch of products arrives.
Heat System
This heat tunnel adopts good eco ability to save your money: heat tunnel with high quality insulation material to save electricity power consumption, with high wrapper efficiency to suit thinner films but achieving the same wrapping quality.
A high level of insulation design has been applied for the heat tunnel, so as to minimise the heat energy loss and greatly cut down the unnecessary cost for your power consumption. To lower the any damage possibility on the outfeed unit, it will automatically cool the product batches when it emerge from the heat tunnel.

Working principle of the shrink wrapping machine for beverage production
The bottle and other container which need to be packed is transferred to block bottle plate along bottle separate device. The bottle conveyor will stop when photoelectrical inspector on the top send out a signal, while block bottle plate stand back to release pressed force of bottle. The separate plate up rises to separate packing bottle and bottles to be packed. Push bottle device pushes packing bottle and film along with guild bottle device to sealing & cutting position, meanwhile pushes the last package onto conveyor of thermal shrinkage equipment, meanwhile film feeding device is working. Then the thermal sealing & cutting move downward, to sealing and cutting. The package which been pushed on to thermal conveyor is go ahead and finish thermal shrinking function, finally it goes to storage shelf after cooled by cold wind. The above process fulfills an automatic packing cycle.
The above movements are all done by air cylinder under PLC control, except conveyor system.

Press“seclude bottle”:split the bottles on conveyor
Press “push bottles” : Separate bottles into one packing, then push separate bottles, they are composite move, and set correspond time well.Touch “package press”:package press is convenient for covering film& sealing film.
Press”package press”, pressing bottles package before film press for better film placing, sealing and cutting.
Press“film press”: touch “film press”, the film at extreme lower position, touch “film press” again, cancel the action of press film, the cylinder back to original place.
Press“cool”: Touch “cool” can accomplish cooling working
Press“shrink cutting”:it is a process of cutting film, touch one time, it can accomplish press bags, cutting film, set cutting film actions& cutting time well.
Arisen break down, then work out break down, press“ fault reset” ,then the machine can re-start working.
Set parameter as picture(6):
1.“shrink cut time”: Holding the cutter at the lower end of waiting time 0.5 ~ 1.2S
2.“cool time”: After heat shrink are all completed, then cooling time 0.5 ~ 2.0S
Seclude time: There photodetector material in place, after a delay, seclude bottle time is usually 0.3 ~ 0.8S
4.“Push bottle delay time”: After the completion of seclude bottles, after a delay push package usually 0.2 ~ 0.8S
5.“Push bottle stay time”: Refers to pushed back the package in place then delay for some time and then back into place, usually 0.3 ~ 0.6S.
6.“Reverse time”: Photodetector the bottle in place, the forward stop and reverse open 0.1 ~ 0.3S, easy to push the bottle.
“Lack bottle time”: This parameter is only delivery device head, otherwise no need to set, mainly to prevent the bottle conveyor is insufficient to ensure that each bottle pushing the number of correct
8.“Save parameter”: This button means after parameters are set well, in order to prevent parameter is missing after the machine a long time off working, press this button will call the stored parameters automatically
Note: The first start to use the machine or turn on the machine after a long time stopping, pls check the settings interface parameter settings are normal first, otherwise the device is not operating normally, the specific parameter values can be found in Table (1)

Installation and maintenance of the shrink wrapping machine for beverage production
Installation of machines
First labelingpushed by the roller to position, regulate the delivery and the sleeve labeling machine output is the or to the same level, as your need to adjust connecting Next, adjust the seclude bottle deflector and guardrail installed as needed and adjust distance, the bottles can be adjusted by hand before. And then install and adjust the four photodetectors point position and height.
PushShrinking machine to the back of labeling machine, adjustment it 90 degrees.
Rotaryscrew of beneath four feet of labeling machine to make fixed equipment rises, according to the height of filling machine to adjust the height of shrink machine. Adjust woking height between filling machine and shrink machine is same, then the foot nut tightened.
Adjust feetof Shrinking machine to make it to a substantially horizontal height, the same foot nut tightened.
The Order of the shelves located behind the shrinking machine, adjust the height of conveyor belt same with shelves’level, and finally tighten the nuts of
The main control box side has a protruding threading pipe, connect the control lines to right place, closethe rear door, it sits at the side of labeling machine back bottle conveying machine.
Turn onthe power and compressed air, on the display screen selected manual position, idling each operation check again, and check if the motor direction of rotation meet the requirements.
Finally, select “Auto” positionon display, the empty state press the green “Auto” button, then bottle conveying the work, and then use the opaque plate while blocking four photodetectors (when plate stretch out, the plate was immediately withdrawn), the device automatically enters the work program. Note: can only block the photoelectric switch in the bottle conveying the work, each time a block is one At this time all the equipment installation and testing is completed.
Maintenance of equipment
① equipment must be grounded reliability, it is particularly important to do production in the high humidity environment
② removed garbage before turn on the machine
