砂浆袋装物料缠绕包装机是一种专为袋装砂浆、腻子粉、瓷砖胶等干粉状或颗粒状物料设计的自动化包装设备。这种机器通过拉伸薄膜对码放在托盘上的袋装物料进行环绕包裹，以提供稳定、紧凑且防尘防水的包装效果，从而在运输和储存过程中保护物料不受潮湿、污染和破损。

其工作原理通常包括以下步骤：

1. 

托盘定位：首先将装满袋装砂浆物料的托盘放置到缠绕机的工作台上。

2. 

薄膜固定与拉伸：机器自动释放预先切割好的拉伸薄膜，并利用预拉装置对薄膜进行适度拉伸，以提高包装紧实度并节省薄膜成本。

3. 

自动缠绕：旋转臂按照预设程序围绕托盘上的物料进行多层交叉缠绕，确保每袋物料都能被薄膜均匀覆盖。

4. 

切断与贴合：缠绕结束后，薄膜会通过热熔或冷粘的方式切断并牢固贴合在自身上，形成稳定的包装结构。

5. 

出料：完成包装后的托盘由输送系统送出，准备进入下一环节。

这种包装方式提高了工作效率，降低了人工成本，并有助于实现生产线的连续作业和物料搬运过程中的安全性。

Mortar bag material wrapping machine is an automatic packaging equipment specially designed for dry powder or granular materials such as bagged mortar, putty powder, tile glue, etc. The machine wraps the bagged material stacked on a pallet with stretch film to provide a stable, compact and dustproof and waterproof packaging that protects the material from moisture, contamination and breakage during transport and storage.

How it works typically consists of the following steps:

1. 

Pallet positioning: First, the pallet filled with bagged mortar material is placed on the table of the wrapping machine.

2. 

Film fixation and stretching: The machine automatically releases the pre-cut stretch film, and uses the pre-stretching device to stretch the film moderately to improve the packaging compactness and save the film cost.

3. 

Automatic wrapping: The rotating arm cross-wraps multiple layers around the material on the pallet according to a preset program to ensure that each bag of material is evenly covered by the film.

4. 

Cutting and lamination: After the winding is completed, the film will be cut by hot melt or cold bonding and firmly attached to itself to form a stable packaging structure.

5. 

Discharging: The pallets after the packaging are sent out by the conveyor system and are ready to enter the next link.

This type of packaging increases productivity, reduces labor costs, and helps to achieve continuous operation of the production line and safety during material handling.
