大型货物缠绕包装机是一种专为体积大、重量重的货物设计的自动化包装设备，主要用于提高货物运输过程中的稳定性、防尘、防水及减少因搬运和运输过程中造成的潜在损坏。这种包装机主要采用预拉伸薄膜或拉伸膜对货物进行环绕裹包。

以下是一些典型特点：

自适应高度调节

：根据货物的高度自动调整转盘高度或者薄膜架的高度，以确保薄膜能够紧密贴合包裹在货物表面。

预拉伸技术

：通过预拉伸机构将薄膜预先拉紧，这样既节约了材料成本，又使薄膜具有更好的包裹效果和紧固性。

旋转台结构

：托盘转动式包装方式是常见的一种类型（如T系列-托盘缠绕机），通过转台带动托盘上的货物旋转，同时薄膜架固定不动或做往复运动进行薄膜缠绕。

智能控制系统

：配备先进的PLC控制系统，可以根据不同货物尺寸和包装要求设置包装层数、转速、拉伸比等参数，并具备故障诊断与安全防护功能。

自动断膜与贴接

：完成包装后能自动切断薄膜并利用热熔胶或搭接的方式实现薄膜尾部的牢固粘接。

定制化设计

：针对特殊形状或超大尺寸的货物，可以提供定制化的解决方案，包括非标机型的设计与制造。

高效节能

：现代大型货物缠绕包装机通常注重能源效率，采用低能耗部件和技术来降低运行成本。

综上所述，大型货物缠绕包装机广泛应用于化工、建材、食品、饮料、家电、造纸、物流等行业的大宗货物包装环节，大大提高了包装作业的效率和质量。

Large cargo wrapping machine is an automatic packaging equipment designed for large volume and heavy goods, which is mainly used to improve the stability, dustproof, waterproof and reduce potential damage caused by handling and transportation during cargo transportation. This type of packaging machine mainly uses pre-stretch film or stretch film to wrap around the goods.

Here are some typical features:

Adaptive height adjustment

: Automatically adjust the height of the turntable or the height of the film rack according to the height of the goods to ensure that the film can be tightly wrapped on the surface of the goods.

Pre-stretching technology

: The film is pre-tensioned through the pre-stretching mechanism, which not only saves the material cost, but also makes the film have a better wrapping effect and fastening.

Turntable structure

Pallet rotation packaging is a common type (such as T series - pallet wrapping machine), which drives the goods on the pallet to rotate through the turntable, and the film rack is fixed or does reciprocating motion for film winding.

Intelligent control system

Equipped with advanced PLC control system, it can set the number of packaging layers, speed, stretching ratio and other parameters according to different cargo sizes and packaging requirements, and has the functions of fault diagnosis and safety protection.

Automatic film breaking and bonding

After the packaging is completed, the film can be automatically cut off and the film tail can be firmly bonded by hot melt adhesive or lap joint.

Customized design

For special shapes or oversized goods, we can provide customized solutions, including the design and manufacture of non-standard models.

Energy-efficient

: Modern large-scale wrapping machines often focus on energy efficiency, employing low-energy components and technologies to reduce operating costs.

To sum up, large-scale cargo wrapping machines are widely used in bulk cargo packaging in chemical, building materials, food, beverage, home appliances, papermaking, logistics and other industries, which greatly improves the efficiency and quality of packaging operations.
