1、 Definition and structural characteristics

Forward push label feeder is an automated feeding equipment designed specifically for roll shaped labels, which utilizes a "platform to carry forward push peeling"
To achieve precise label delivery. Its core structure includes the following parts:

Platform structure: A platform made of materials with anti sticking properties is used, which can effectively avoid the situation of labels getting stuck due to adhesive problems.

Drive system: The drum/gear is driven by a stepper motor or servo motor, which can achieve low friction feeding and has adjustable feeding speed
(For example, supporting 9-speed adjustment).

Control system: Integrated with PLC or intelligent module, supporting the use of fiber optic sensors for positioning (positioning accuracy within ± 0.15mm to ± 0.2mm)
It has a closed-loop feedback function and can dynamically adjust the feeding length.

Stripping mechanism: achieved by flipping the peeling knife or mechanical structure to separate the label from the base paper, capable of supporting synchronous peeling of single or multiple rows of labels
Get away from the operation.

2、 Working principle

Loading and tension control: The label roll is fixed on the platform, and the tension device ensures that the material remains flat; The feeding shaft is compatible with 75
Label rolls with an inner diameter of mm or 150mm.

Drive and positioning: The motor drives the drum to pull the label forward. When the fiber optic sensor detects the preset position, it triggers the shutdown operation, and then
Cooperate with labeling equipment to complete the labeling process.

Accuracy guarantee: The encoder can monitor the motor's speed in real time, and the friction brake device can prevent overshoot caused by inertia, ensuring that the machine is stopped
Stability.

3、 Typical application scenarios

electronics manufacturing

Suitable for the bonding work of precision accessories such as mobile phone battery labels and FPC reinforcement sheets, it can support a bonding accuracy of ± 0.2mm.

Pharmaceutical Packaging

It can achieve continuous transportation of drug aluminum foil labels and instructions, and be linked with the visual system to achieve labeling accuracy of ± 0.1mm level.

Food and Daily Chemicals

Capable of meeting the high-speed labeling requirements for bottled/boxed products (with a production capacity of over 400 cans per minute).

4、 Technical advantages and limitations

Advantage:

Capable of compatibility with single/multi row labels and adaptable to flexible production modes for ultra-thin materials (thickness<0.1mm);
Limitations: Wrinkles are prone to occur, and the labeling accuracy is relatively high (accuracy range is ± 0.15mm to ± 0.2mm). During long-term operation,
Regular maintenance of transmission components is requiredSupport rapid material replacement operation (using pull-out slide rail design) with initial purchase cost higher than simple vibration feeding
Feeder

5、 Selection suggestions

parameter matching

In terms of speed: In medium and low-speed application scenarios, stepper motors can be selected; And in high-speed application scenarios (such as production capacity reaching 600 pieces/minute)
For the above, a servo motor needs to be selected.

In terms of material thickness: For labels with a thickness greater than 0.15mm, priority should be given to choosing a platform feeder; For ultra-thin materials, customization is required
Vacuum adsorption scheme.

Brand and Maintenance

Recommended domestic brands: Longhai Huanyu (labeling accuracy up to ± 0.15mm), Yuqi Precision (adopting integrated design), Sanyi Intelligent (with
Equipped with 9-stage speed regulation function.

Regular maintenance is required for vulnerable parts such as synchronous belts and bearings to avoid equipment accuracy degradation.

VI. Summary

Forward push label feeder, with its characteristics of "high precision and strong compatibility", has become the mainstream feeding solution for industries such as electronics and pharmaceuticals
Plan. When selecting, it is necessary to consider the characteristics of the material and the specific needs of the production line, and prioritize the selection of intelligent control (such as closed-loop reverse)
Provide feedback functions and improve the brand's after-sales support to enhance the overall efficiency of equipment use
