主要特點

1. 大承載能力

：大型復合板托盤纏繞機設計時充分考慮了對大尺寸、重載荷托盤的處理能力，能夠穩定地對裝載大量貨物或重型貨物的復合板托盤進行纏繞包裝。

2. 高強度結構

：設備主體采用高強度鋼材制造，確保在長期、重負荷作業下的結構穩定性，并能抵抗因托盤旋轉產生的離心力。

3. 精準控制

：配備先進的電子控制系統和伺服驅動技術，實現對纏繞速度、拉伸比、層數、轉角等參數的精確控制，滿足不同貨物包裝需求。

4. 適應性廣

：能夠適應多種規格的復合板托盤以及不同類型的纏繞膜（如預拉伸膜、手用膜等），并可通過調整或加裝附件適應特殊形狀或高度不一的貨物。

5. 安全性高

：設有緊急停止按鈕、光電感應防護裝置等安全措施，防止操作人員誤傷及設備異常情況下的及時停機。

6. 節能高效

：采用節能電機和優化的傳動系統，減少能耗的同時提高包裝效率，有助于降低運營成本。

工作原理

大型復合板托盤纏繞機的工作流程一般包括以下幾個步驟：

裝載托盤

：將裝滿貨物的復合板托盤放置在纏繞機的轉臺上。

固定與啟動

：通過機械或液壓方式壓緊托盤，防止其在旋轉過程中移動。啟動設備后，轉臺開始勻速旋轉。

薄膜纏繞

：纏繞膜架上的薄膜隨轉臺轉動而釋放，并通過預拉伸機構（如有）預先拉伸薄膜以增強包裹力。薄膜均勻地裹覆在托盤及貨物上，形成多層螺旋狀包裹層。

封口與斷膜

：當達到設定的纏繞層數或高度后，設備自動切斷薄膜并進行熱熔或膠帶封口，確保纏繞膜的末端牢固粘貼在托盤上。

卸載托盤

：完成纏繞包裝的托盤被移出纏繞區域，準備進行下一步的物流或存儲操作。

常見配置

? 轉臺

：中心帶有滾軸或滾筒的旋轉平臺，承載托盤并帶動其旋轉。

? 膜架系統

：包括膜卷支架、膜卷軸、張力調節裝置、膜端夾持器等，用于安裝纏繞膜卷并控制薄膜釋放。

? 預拉伸機構

（可選）：通過電動或氣動方式拉伸薄膜，提高包裝緊度和薄膜利用率。

? 升降機構

（可選）：使膜架上下移動，適應不同高度的貨物或實現頂部覆蓋纏繞。

? 控制系統

：包含操作面板、PLC控制器、變頻器等，用于設定和監控包裝參數、設備狀態。

? 安全裝置

：如光電感應器、急停按鈕、防護欄桿等，保障操作安全。

綜上所述，大型復合板托盤纏繞機是針對復合板材質托盤特性和重型貨物包裝需求而設計的專業化包裝設備，憑借其強大的承載能力、精準控制、高適應性和優良的安全性能，有效提升物流包裝效率和貨物保護水平。

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.
