Bottle shrink wrap machine is deeply recognized by customers, which is used in beverage packaging, mineral water packaging, beer packaging, glass bottle packaging, can packaging and other items for heat shrink packaging, so a large number of customers come to buy and use. can be connected with production to automatically feed, wrap, seal and shrink. Through the partition mold and the distribution convey line, sort the bottles into multiple rows and push the whole package to complete the bundle packaging. Format like 2×3, 3×4, 4×6 or any other packs. Speed can be 8 to 20 bundles per min, especially suitable for batch beverage or water production. So it is very important to operate it well. As a professional shrink machine manufacturer, the editor of SNCPACK to share some experience in the use of bottle shrink wrap machine.

Operation flow of automatic bottle shrink wrap machine

1. Put the automatic bottle  shrink wrap machine on the flat ground (be sure to ensure the level of the work table), and check whether the parts of the machine are loosened or shifted in the process of re-transportation. After checking correctly, connect to the power supply.

2. Install the propulsion cylinder kit attached to the packing box according to the instructions (in order to better fix the equipment and save packing space during shipping, some of the cylinders and conveying are disassembled)

Adjust bottle size and template

3. Connect the conveying table of the bottle shrink wrap machine, and adjust the distance between the guard plate and the isolation plate at the edge of the conveying table.

4. Adjust the cuff type automatic heat shrink packaging machine positioning gate, which is driven by a constant pressure cylinder, and its main function is to prevent the back package from squeezing the package in front of the propulsion plate. When mediating, make the knife just between the bottle and the bottle.

5. Connect one end of a flexible pipe with an outer diameter of 8 MM to the air source, and the other end to the air intake joint of the lower part on the right side of the machine, push the pipe into place, and finally fasten it with bolts.

6. When the air source pressure is ≥ 6kg/cm2, check whether the pressure gauge is at 4-6kg/cm2. When the machine is running normally, the pressure should not exceed 6kg/CM2, and the air source pressure of the external joint should not exceed 9.5kg/CM2.

7. Turn on the bottle shrink wrap machine power supply, adjust the appropriate sealing time, generally set to about 1.5 seconds, the specific sealing experiment can be determined; set constant pressure delay, the function of this delay is to reduce the inertia of the conveying line to squeeze the packaging already in place, so it is set to about 0.5 seconds. The setting of the detection delay is to make the last package in place smoothly, which is set at about 0.4 seconds. 

The above is only applicable to similar models, you need to refer to the manual

8. According to the material thickness of the shrink film, set the sealing temperature, which is about 180 °C.

9. According to the size of the package, adjust the travel of the package, adjust the pressing plate of the fixed package, and adjust the speed of the conveyer before and after.
10. After the above operations are completed, the work can be carried out.
