二、主要特点

1. 精准称重：

• 采用高精度称重传感器和先进的计量控制系统，确保每袋物料的重量精确无误。称量精度通常可达到±0.2%或更高，部分设备甚至能达到更高的精度要求。

• 自动去皮、自动校正等功能，进一步提高了称重的准确性和稳定性。

2. 给袋式自动灌装：

• 自动供袋装置将预制的吨袋输送到包装工位，无需人工干预。

• 开袋装置（如吸盘、机械臂等）自动打开吨袋口，准备接受物料填充。这不仅提高了包装效率，还减少了人工操作带来的误差和污染风险。

3. 高效自动化：

• 整个包装过程高度自动化，包括供袋、开袋、称重、充填、封口、切断等步骤。可根据生产需求设定包装速度，通常可达到每小时数十至数百袋不等。

• 自动化程度高，减少了人工操作环节，降低了劳动强度。

4. 多功能一体化：

• 部分机型配备除尘系统、防爆系统等装置，适用于不同物料和特殊环境的包装需求。

• 可根据客户需求定制各种规格和功能的包装机，满足不同行业的包装要求。

5. 操作简便：

• 配备先进的PLC控制系统和触摸屏操作界面，操作简便直观。

• 自动化程度高，降低了对操作人员的技能要求，减少了培训成本。

三、工作原理

吨袋包装机的工作原理主要包括以下几个步骤：

1. 自动供袋：将预制的吨袋放置在供袋装置上，设备自动将吨袋输送到包装工位。

2. 开袋与定位：开袋装置自动打开吨袋口，并通过定位装置确保吨袋位置准确。

3. 精准称重：物料通过输送装置进入称重斗进行精准计量，达到设定重量后停止进料。

4. 快速充填：计量完成后，物料快速充填到吨袋中。部分机型采用气力输送或螺旋输送等方式进行充填。

5. 封口与切断：充填完成后，封口装置对吨袋口进行热压封口或缝制封口，确保封口牢固可靠。然后切断装置将吨袋从供袋装置上切断，形成独立的包装单元。

综上所述，吨袋包装机（精准称重、给袋式自动灌装设备）是一种高效、精确、自动化的包装设备，广泛应用于多个行业。在选购时，建议综合考虑生产需求、设备质量、操作简便性和性价比等因素。

Big bag packaging machine, especially those equipment with accurate weighing, bag-feeding automatic filling function and high measurement accuracy, is an indispensable packaging equipment in modern industrial production. Here's a closer look at this type of device:

1. Product Overview

The ton bag packaging machine integrates multiple functional modules such as automatic bag feeding, accurate weighing, rapid filling, sealing and cutting, etc., which can automatically complete the entire packaging process. It is suitable for ton bag packaging of various powders and granular materials, such as montmorillonite, flour, starch, etc. Through a high degree of automation and precise control, this equipment significantly improves packaging efficiency and product quality.

Second, the main features

Accurate Weighing:

High-precision load cells and advanced metrology control systems are used to ensure that the weight of each bag of material is accurate. Weighing accuracy can often reach ±0.2% or more, and some equipment can even achieve higher accuracy requirements.

Automatic tareping, automatic correction and other functions further improve the accuracy and stability of weighing.

Automatic filling of bag type:

The automatic bag feeding device conveys the prefabricated big bags to the packaging station without human intervention.

The bag opening device (such as suction cup, robotic arm, etc.) automatically opens the mouth of the ton bag, ready to accept the material filling. This not only improves packaging efficiency, but also reduces the risk of errors and contamination caused by manual handling.

Efficient Automation:

The whole packaging process is highly automated, including bag feeding, bag opening, weighing, filling, sealing, cutting and other steps. Packing speeds can be set according to production needs, typically ranging from tens to hundreds of bags per hour.

The degree of automation is high, which reduces the manual operation link and reduces the labor intensity.

Multi-functional integration:

Some models are equipped with dust removal systems, explosion-proof systems and other devices, which are suitable for packaging needs of different materials and special environments.

Packaging machines with various specifications and functions can be customized according to customer needs to meet the packaging requirements of different industries.

Easy to operate:

Equipped with advanced PLC control system and touch screen operation interface, the operation is simple and intuitive.

The high degree of automation reduces the skill requirements of operators and reduces training costs.

Third, the working principle

The working principle of the ton bag packaging machine mainly includes the following steps:

Automatic bag feeding: The prefabricated ton bags are placed on the bag feeding device, and the equipment automatically conveys the ton bags to the packaging station.

Bag opening and positioning: The bag opening device automatically opens the mouth of the ton bag, and ensures the accurate position of the ton bag through the positioning device.

Accurate weighing: The material enters the weighing hopper through the conveying device for accurate measurement, and stops feeding after reaching the set weight.

Fast filling: After the measurement is completed, the material is quickly filled into the ton bag. Some models are filled by pneumatic conveying or screw conveying.

Sealing and cutting: After the filling is completed, the sealing device will hot-press and seal or sew the mouth of the ton bag to ensure that the sealing is firm and reliable. Then the cutting device cuts the ton bag from the bag feeding device to form an independent packaging unit.

To sum up, the ton bag packaging machine (precision weighing, bag-feeding automatic filling equipment) is an efficient, accurate and automated packaging equipment, which is widely used in many industries. When purchasing, it is recommended to comprehensively consider the production needs and equipment quality
