Two independent label disks are used to reduce the time used to replace label rolls in production and improve production efficiency.
High transmission power, compact structure of the transmission system, thin belt body, rich flexibility, suitable for high-speed transmission, low heat generation, stable rotation, heat resistance, oil resistance, wear resistance, low elongation in use, and long service life.
Bottle feeding mechanism:
Dedicated bottle feeding screw with torque limiter installed to ensure stable and reliable high-speed bottle feeding. Both the screw and bottle protecting push plate are fast.
The structure is dismantled, and all positioning and adjustment are completed at one time, no adjustment is required in the later period, and the replacement of the mold is simple and quick.
Bottle inlet and outlet star wheel:
Connected with the main turntable gear, responsible for the transition between the bottle feeding screw and the main turntable, install torque limiter, quick-release structure, and all have positioning, one adjustment is completed, no adjustment is required in the later period, and the replacement of the mold is simple and quick.
The Working Principle of Labeling
- The hot melt adhesive OPP labeling machine is a new type of labeling machine with the rotary and continuous operation; the equipment can automatically adjust the in and out the transmission of the container; the container conveyed by the conveyor belt is separated by the separation screw according to the spacing of the star wheel After a certain distance, the bottle-in star wheel transfers the container to the container turntable. After the container is fixed by the bottle pressing mechanism and the container’s mold seat, the container starts to rotate at a certain speed for positioning and labeling.
- When the container reaches the detection position of the electric eye, the computer host controls the label delivery system to deliver the label. When a label delivery action is completed, the high-speed cutter cuts off a label; due to the use of Yaskawa’s small inertia high-speed servo motor, high-speed label delivery is guaranteed. Accuracy and stability of label cutting.
- The cut labels are sent to the gluing system; in this part, the system applies glue to the two parts of the label’s leading and trailing edges. This gluing method minimizes the consumption of hot melt adhesive.
- When the glued label is transferred to the labeling position, the label can accurately and effectively adhere to the container. Since the container is in a rotating state during the transfer process of the label, the label can be affixed to the container smoothly and tightly. The adhesive strip at the end of the sizing can form a good label lap seal, completing the labeling process.
Equipment Safety Protection Function Part
When the power supply has overvoltage, Undervoltage, phase loss, or phase error, it will cut off the main circuit and give an alarm to prevent damage to electrical components.
When the protective door is opened, the equipment is prohibited from running and starting, and the emergency stop switch can be pressed in an emergency state to prevent personal injury.
Label status: When the label is used up, it will slow down and stand by and give an alarm to remind you to replace the label. When the label tension is abnormal, it will stop and alarm to reduce the influence of label stretching on label cutting accuracy. When the color mark detection is continuously lost and the mark cut deviation is too large, the machine will stop and alarm to reduce the unqualified products.
when the temperature of the glue does not reach the melting value, the equipment is prohibited from starting to prevent damage to the equipment. When the temperature of the glue exceeds the upper limit, the probe is open, and the heater is disconnected, it stops heating and shuts down and alarms. When the glue tank level is low, the glue When it is about to run out, it will give an alarm and wait for a delay in slowing down.
Missing labeling alarm:
When there is labeling missing, the equipment will slow down and stop the alarm to prevent the label drum from being cut and reduce the downtime.
When there is a shortage of bottles at the end of the bottle or the end of the bottle is blocked, the equipment will slow down and stand by, the standby indicator will prompt, and the production speed will automatically resume after the state is released.
When the servo drive and variable frequency drive fail, and the control power supply is short-circuited, the equipment stops and alarms.
Air pressure detection:
When the air pressure does not meet the production requirements of the equipment, the equipment will be shut down to prevent the production of defective products.
When the main turntable, the feeding screw, and the bottle star wheel are blocked and jammed, the machine will stop and alarm.
