450L+BS-4020 Heat shrink machine is a new type of arbitrary combination of automatic laminated film sealing heat shrink packaging machine, which belongs to the film sealing heat shrink packaging machine. There is a feeding bracket, the lower conveyor belt and the upper conveyor belt are installed on the upper end of the feeding bracket; the front end of the feeding frame is connected with a stacked feeding bracket, and the front end of the stacked feeding bracket is a film sealing and cutting mechanism; the stacked feeding bracket is close to the upper and lower conveyors There is a lifting table at the belt. The two sides of the upper end of the lifting table are provided with turning blades, the top of the lifting table is provided with a turning start motor, and the middle of the stacking feeding bracket is a stacking table. The upper side of the stacked feeding bracket is equipped with a counting switch that rises to the upper conveyor belt, and the upper end of the stacked feeding bracket is also provided with a bulletproof device for the packaged objects near the upper and lower conveyor belts. When working, according to the number of packages to be imported, it can be packaged from one item to one hundred, or even any package of more items.

The working principle of 450L+BS-4020 Heat shrink machine is to use the heat shrinkable film to change the irregular arrangement of the original molecules in the heated state. Under the heat radiation such as infrared rays, the plastic molecules are rearranged tightly, so that the original area It is greatly reduced and attached to the surface of the product to achieve the purpose of packaging.

Maintenance tips of 450L+BS-4020 Heat shrink machine

450L+BS-4020 Heat shrink machine Some parts need regular maintenance, so which parts of the heat shrink machine need regular maintenance?
1. We must check some parts regularly, such as once every half a month or once a month. The inspection parts include: worm gear, worm, bolts on the lubricating block, bearings and other moving parts to see if these parts are flexible and wearable. , If defects are found, they should be repaired in time, and should not be used reluctantly.
2. Secondly, the heat shrinking machine should be used in a dry and clean room, and must not be used in places where the atmosphere contains acids and other gases that are corrosive to the body.
3. After using the 450L+BS-4020 Heat shrink machine, you should take out the rotating drum to clean and brush the remaining powder in the bucket, and then install it properly to prepare for the next use.
4. If the drum moves back and forth during work, please adjust the M10 screw on the front bearing to the proper position. If the gear shaft moves, please adjust the M10 screw at the back of the bearing frame to an appropriate position, adjust the clearance so that the bearing does not make noise, and the hand pulley should be properly tightened. Too tight or too loose can cause damage to the machine.
5. Finally, if the packaging machine equipment is not used for a long time, the whole body of the machine must be cleaned, the smooth surface of the machine parts should be coated with anti-rust oil, and covered with a cloth. If the device has not been used for a long time, it must be checked whether all parts are normal before it can be turned on.
