Let's talk about the wrapping machine.

The wrapping machine, also known as the winding packaging machine, is a device that fully or partially wraps goods through flexible packaging materials (such as stretch film, heat shrink film, etc.), aiming to meet the packaging requirements of goods for containerized storage, transportation and mechanical loading and unloading operations. The following is a detailed introduction to the wrapping machine:

I. Working Principle

The working principle of the wrapping machine is mainly based on the coordinated movement of the rotation of the turntable and the lifting and lowering of the mold frame. The specific steps are as follows:

Goods positioning: Place the wrapped object in the center of the turntable.

Turntable rotation: Start the turntable motor to drive the turntable to rotate, enabling the object to be wrapped and wound around the periphery.

Mold frame lifting: At the same time, the elevator motor starts, driving the winding and strapping machine assembly to move up and down, achieving the winding of objects in the height direction.

Complete packaging: Through the coordinated movement of the turntable and the mold frame, the entire surface of the object is wrapped and packaged.

Ii. Classification

Wrapping machines can be classified into various types based on different criteria:

According to the degree to which the packaging is wrapped:

Full wrapping wrapping machines: including knotting type, covering type, form-fitting type, seam type, etc.

Semi-wrapping wrapping machine: Only partially wraps the packaged items.

By structure:

Pallet wrapping machine: It is suitable for packaging goods transported on pallets, such as container transportation of bulk goods and packaging of loose parts on pallets.

Pallet-free wrapping machine: It can wrap and package goods without pallets.

Horizontal winding machine: It achieves winding packaging by rotating the arm system around the goods that are moving at a constant speed horizontally.

Cantilever winding machine: By rotating a cantilever around the goods, it achieves the winding and wrapping of the goods.

Circular winding machine: Through a film (tape) feeding device that runs around a circular track, the circular part of the circular goods is wound and wrapped.

Roller winding machine: It achieves winding and wrapping of the radial cylindrical surface by driving the rotation of the cylindrical goods through two power idlers on the turntable.

Steel band wrapping machine: It uses steel bands as packaging materials to wrap and package goods.

By the degree of mechanical automation:

Fully automatic winding machine: It realizes automated operation without the need for manual intervention.

Semi-automatic winding machine: Some operations require manual intervention, such as placing goods and starting the equipment.

Manual winding machine: Relying on manual operation, it is suitable for small-batch and low-efficiency packaging requirements.

According to the form of the membrane frame structure:

Pre-stretch wrapping machine: It achieves uniform film wrapping by setting the stretch ratio and features a high utilization rate of consumables.

Resistance stretch wrapping machine: It can adapt to different film materials by adjusting the friction damping, but it has insufficient stability for light and high goods.

Mechanical pre-stretching winding machine: It combines mechanical structure to achieve pre-stretching of films.

Iii. Advantages and Characteristics

Strong adaptability: It is not restricted by the size of the packaged object and can be used for winding packaging of goods of various shapes and sizes.

Good packaging effect: It can prevent dust, moisture and keep the packaged items clean, reduce surface scratches on the packaged items and improve surface quality.

High efficiency and low consumption: It adopts PLC automatic control, with reliable performance. The winding method and frequency can be changed as needed to improve packaging efficiency and reduce packaging costs.

Safe and reliable: It features protection functions such as overload and overcurrent to ensure the safe operation of the equipment.

Easy maintenance: The design is simple and clear, making maintenance extremely convenient.

Iv. Application Scenarios

Wrapping machines are widely used in the containerized packaging of products such as foreign trade exports, food and beverages, manufacturing and filling, papermaking, dyes, plastic chemicals, glass ceramics, and mechanical and electrical castings. Specific application scenarios include

Logistics and warehousing: Wrap the goods to facilitate their storage, transportation and mechanical loading and unloading.

Commodity processing: Wrap and package the processed products to protect the surface quality of the products and increase their added value.

Automated production line: Used in conjunction with automated production lines, it realizes the automated packaging and conveying of goods.
