1、 Definition and core characteristics

The retractable Feida feeder (retractable label peeling machine) is an automated feeding equipment designed specifically for roll or sheet labels, which uses reverse
Realize the separation of labels and base paper through peeling technology. Its core features include:

Reverse peeling mechanism: When the device is running, the label backing paper retracts backwards to reduce material stretching deformation, suitable for high-precision scenarios (such as ± 0.1mm precision)
Degree of demand).

Modular design: Supports synchronous peeling of single-layer/double-sided labels, compatible with single row, multi row labels, and irregular sheet materials (such as Mylar sheets and conductive tape).

Intelligent control: Integrated fiber optic sensors and closed-loop feedback system, real-time adjustment of feed length, suitable for high-speed production lines (such as 600 pieces/minute or more).

2、 Typical Structure and Working Principle

core component

Drive system: servo motor precision gear set, combined with tension control module to ensure material flatness.

Sensor positioning: Fiber optic sensors detect the position of labels, with an error controlled within ± 0.1mm.

Stripping mechanism: achieves label separation by retracting the backing paper, reducing static interference and wrinkling risks.

workflow

Loading: The label roll is fixed to the adapter shaft (compatible with 75mm/150mm inner diameter), and the tension device automatically adjusts the tightness.

Stripping: The motor drives the backing paper to retract, and the label is peeled off and pushed to the picking position, which is precisely grasped by a robotic arm.

Correction: The visual system or sensor calibrates the label position in real-time to ensure the accuracy of the attachment.

4、 Selection and maintenance suggestions

Key parameters for selection

Accuracy: In high-speed scenarios, closed-loop control systems (such as Longhai Huanyu LH1406H, with an accuracy of ± 0.1mm) are preferred.

Material compatibility: Labels with a thickness less than 0.1mm require customized vacuum adsorption modules to avoid peeling failure.

Brand recommendation:

Longhai Huanyu: High precision model, supporting non-standard customization.

Ant swarm intelligence: modular design, quick material change (pull-out slide rail).

Maintenance points

Daily maintenance: Clean the sensor and peel off the blade every week to prevent adhesive residue from affecting accuracy.

Replacement of vulnerable parts: Check the synchronous belt and bearings every 3-6 months, and replace them if necessary (cost approximately 200-500 yuan/piece).

5、 Limitations and coping strategies

Limited solutions

Ultra thin materials (<0.05mm) are prone to wrinkling, so adding a vacuum adsorption platform or customizing silicone pressure wheels can assist in peeling.

Regularly calibrate the servo motor encoder for accuracy degradation after long-term operation, upgrade firmware and optimize control algorithms.

The initial cost is relatively high (about 10000-20000 yuan/unit), so choose domestic brand basic models and gradually upgrade the functional modules.
