PP Strap Inward-Winding Conveyor-Type Fully Automatic Winding Machine

Product Introduction

Pursuing perfect winding quality is the core of our machine design. This machine adopts a fully servo-driven system (for both winding shaft and traversing shaft), eliminating errors from traditional mechanical transmission and achieving millimeter-precise traversing and constant tension control. Through a unique tension arm angle feedback and adjustable spring mechanism, the system can fine-tune winding speed and tension in real-time, actively adapting to straps of different weights and widths. All of this serves one goal: to minimize “curvature deformation” and “bridging” after winding, ensuring every coil is tight, flat, and visually uniform, achieving a near-perfect winding state.

Main Functions

1) Uses a servo motor for traversing guidance. Winds PP strapping bands with widths from 5 to 19 mm. Select the corresponding strap width on the touch screen for winding.

2) Requires a paper core (mandrel) and features automatic outer-layer film wrapping. After winding is completed, the machine stops automatically, replaces the paper tube, cuts the strapping band, clamps and secures the band head, wraps the outer layer with film, flips the finished coil 90 degrees onto the conveyor belt, returns to the origin, and continues the automatic winding process. The entire cycle is completed automatically.

3) The winding shaft is driven by a servo gear motor. The winding speed is regulated by controlling the angle position of the tension arm. Tension can be adjusted via the spring screw, allowing appropriate winding tension for strapping bands of different weights or widths, minimizing curvature deformation after winding.

4) After winding is complete, the discharged strapping band is automatically moved onto the conveyor.

5) Measurement modes: Two modes available: by length (meter) and by weight.

Technical Specifications

FAQ:

Q1: What are the advantages of servo drives over ordinary motors? How does it specifically improve my product quality?
A1: Servo motors offer fast response, precise control, and smooth operation. In winding applications, they enable more accurate traversing, preventing edge overlap or uneven gaps; they allow for softer starts/stops and speed changes, reducing instantaneous impact on the strap; combined with tension control, they effectively minimize issues like “tight inner layers and loose outer layers” or deformation caused by tension fluctuations. This directly enhances coil appearance and the smoothness of unwinding in subsequent use.

Q2: How do I adjust the machine to handle different strap specifications?
A2: Adjustments are very intuitive. First, select the corresponding strap width parameter on the touch screen. Secondly, for straps of different weights (thicknesses), manually rotate the “spring adjustment screw” on the machine to change the preset pressure on the tension arm, finding the optimal winding tension. The servo system will automatically optimize its operating parameters.
