工作原理

大型复合板托盘缠绕机的工作流程一般包括以下几个步骤：

装载托盘

：将装满货物的复合板托盘放置在缠绕机的转台上。

固定与启动

：通过机械或液压方式压紧托盘，防止其在旋转过程中移动。启动设备后，转台开始匀速旋转。

薄膜缠绕

：缠绕膜架上的薄膜随转台转动而释放，并通过预拉伸机构（如有）预先拉伸薄膜以增强包裹力。薄膜均匀地裹覆在托盘及货物上，形成多层螺旋状包裹层。

封口与断膜

：当达到设定的缠绕层数或高度后，设备自动切断薄膜并进行热熔或胶带封口，确保缠绕膜的末端牢固粘贴在托盘上。

卸载托盘

：完成缠绕包装的托盘被移出缠绕区域，准备进行下一步的物流或存储操作。

常见配置

• 转台

：中心带有滚轴或滚筒的旋转平台，承载托盘并带动其旋转。

• 膜架系统

：包括膜卷支架、膜卷轴、张力调节装置、膜端夹持器等，用于安装缠绕膜卷并控制薄膜释放。

• 预拉伸机构

（可选）：通过电动或气动方式拉伸薄膜，提高包装紧度和薄膜利用率。

• 升降机构

（可选）：使膜架上下移动，适应不同高度的货物或实现顶部覆盖缠绕。

• 控制系统

：包含操作面板、PLC控制器、变频器等，用于设定和监控包装参数、设备状态。

• 安全装置

：如光电感应器、急停按钮、防护栏杆等，保障操作安全。

综上所述，大型复合板托盘缠绕机是针对复合板材质托盘特性和重型货物包装需求而设计的专业化包装设备，凭借其强大的承载能力、精准控制、高适应性和优良的安全性能，有效提升物流包装效率和货物保护水平。

Large composite plate pallet wrapping machine is an automatic mechanical equipment specially used for efficient and stable wrapping and packaging of pallets made of large composite materials. This type of equipment is usually widely used in logistics, warehousing, manufacturing and other industries, aiming to ensure the safety and integrity of goods in the process of transportation and storage by fastening, dustproof, waterproof, anti-collision and other multiple protections on the goods on the pallet through stretch film. The following is a detailed introduction to the main features, working principle and common configuration of the large composite plate pallet wrapping machine:

Key features:

1. Large carrying capacity

The design of the large composite plate pallet wrapping machine fully considers the processing capacity of large-size and heavy-duty pallets, and can stably wrap and package composite pallets loaded with large quantities of goods or heavy goods.

2. High-strength structure

The main body of the equipment is made of high-strength steel to ensure structural stability under long-term and heavy-duty operation, and can resist the centrifugal force generated by the rotation of the pallet.

3. Precise control

Equipped with advanced electronic control system and servo drive technology, it can accurately control the winding speed, stretching ratio, number of layers, turning angle and other parameters to meet the needs of different cargo packaging.

4. Wide adaptability

: It can adapt to a variety of specifications of composite board pallets and different types of stretch film (such as pre-stretch film, hand film, etc.), and can be adjusted or installed with accessories to adapt to special shapes or different heights of goods.

5. High security

It is equipped with emergency stop button, photoelectric induction protection device and other safety measures to prevent accidental injury of the operator and timely shutdown of the equipment under abnormal conditions.

6. Energy saving and high efficiency

: The use of energy-efficient motors and an optimized drive system reduces energy consumption while improving packaging efficiency, helping to reduce operating costs.

How it works

The workflow of a large composite plate pallet wrapping machine generally includes the following steps:

Load pallets

: A pallet of composite panels filled with goods is placed on the turntable of the wrapping machine.

Fixed & Activated

: Mechanically or hydraulically press the pallet to prevent it from moving during rotation. After starting the machine, the turret begins to rotate at a constant speed.

Film wrapping

: The film on the stretch film frame is released as the turntable rotates, and the film is pre-stretched by a pre-stretching mechanism (if any) to enhance the wrapping force. The film is evenly wrapped around the pallet and the cargo, forming a multi-layer spiral wrap.

Sealing and film breaking

When the set number of ply layers or height is reached, the machine automatically cuts the film and seals it with hot melt or tape to ensure that the end of the preform film is firmly attached to the tray.

Unload the pallet

: The pallet that has been wrapped is removed from the wrapping area and is ready for the next logistics or storage operation.

Common configurations

• Turntable

: A rotating platform with rollers or rollers in the center that carries the pallet and drives it to rotate.

• Membrane rack system

: Including film roll holder, film reel, tension adjustment device, film end gripper, etc., for installing the spiral film roll and controlling the film release.

• Pre-stretching mechanism

(Optional): Stretch the film electrically or pneumatically to improve package tightness and film utilization.

• Lifting mechanism

(Optional): Move the film frame up and down to accommodate loads of different heights or to achieve top cover wrapping.
