World-Leading Technology PP Woven Block Bottom Valve Sack Production Line

World-Leading Technology PP Woven Block Bottom Valve Sack Production Line

Valve bag is a special packaging bag with a square bottom and a valve that can stand on its own and facilitate filling and discharging materials. Gachn group valve sack making machine Wholesaler is an automated equipment used to produce valve bags. It is different from the traditional automatic completion of a series of processes such as bag making, sealing, and cutting, thereby greatly improving production efficiency and reinforcing the quality of bottom stickers. The application of valve bags in the mineral field is indeed crucial, especially in the transportation and storage process of coal powder, ore powder and other minerals, because of its easy filling, recyclability, and high-speed production efficiency

There are significant differences between using GACHN GROUP valve bags and traditional transport vehicles for packaging, which are mainly reflected in the following aspects:

Structure and Design

Gachn group valve pocket:

There is a valve device in the center of the bag mouth, which can open and close the bag through compressed air.

It is divided into outer valve bag and inner valve bag. The sealing methods are different, but they can all achieve automatic or manual sealing.

Bulk:

It may be simpler in structure and has no valve device.

Sealing methods may require additional tools or steps, such as sewing, binding, etc.

Functions and features

Gachn group valve pocket:

It has good sealing performance and can effectively prevent leakage and contamination of minerals during transportation and storage.

It is easy to load and unload, and can be quickly filled and emptied through the valve, saving time and manpower.

Highly breathable, it facilitates ventilation and drying of minerals and reduces the risk of mildew and moisture.

It can be used repeatedly and has good moisture-proof, dust-proof, shock-proof and other functions.

Bulk:

The sealing performance may be poor, which may easily lead to leakage and contamination of minerals.

The loading and unloading process can be more tedious and require more time and manpower.

Breathability may be insufficient, which can easily lead to mineral moisture and mildew.

It is more likely to be used once, which is not conducive to environmental protection and cost control.

Applicability and efficiency

Gachn group valve pocket:

Suitable for packaging of various minerals, especially powdery or granular minerals.

It can improve packaging efficiency and accuracy and reduce material loss.

Neat and neat palletizing method makes transportation safer and more stable.

Bulk:

Applicability may be limited, particularly for packaging of powdered or granular minerals.

Packaging efficiency and accuracy may be low, easily leading to material loss.

The palletizing method may not be neat and stable enough, increasing risks during transportation.

Cost and environmental impact

Gachn group valve pocket:

The initial cost is higher, but over time the overall cost may be lower due to its reusability and efficiency.

It is beneficial to environmental protection and reduces the generation of packaging waste.

Bulk:

The initial cost is lower, but over time the overall cost may be higher due to its one-time use and lower efficiency.

The impact on the environment may be even greater.

There are significant differences between the use of valve bags for mineral packaging and the use of traditional car packaging in terms of structure and design, functions and characteristics, applicability and efficiency, as well as cost and environmental impact. In order to give valve bags superior performance and characteristics, GACHN Group's Production valve bag Machining Supplier has wider application prospects in the field of mineral packaging. Therefore, GACHN Group has developed the following products for the sealing, breathability, and tensile properties required for packaging minerals. Function:

Gachn group blowing uniform technology:

The quality of the back cover is the most important part of the valve bag production process. Instable back cover welding, gaps, and uneven pasting will cause serious quality problems such as bag breakage, powder leakage, and bottom sticker peeling off.

In order to improve the accuracy of patching, we also introduced a color mark motion tracking system. The system of Gachn group pp woven block bottom valve sack making machine Producer can identify and track the color mark on the patch to ensure that the position and angle of the patch are always consistent during the transportation process. The heat sealing welding system used in the bottom patch part has achieved efficient and stable performance by virtue of its unique technical advantages. Welding effect. The heat sealing welding system adopts uniform air blowing technology to ensure more uniform heat distribution during the welding process. This not only improves the welding quality, but also avoids welding defects caused by uneven heat. In order to achieve stable and reliable welding temperature, we adopt a constant temperature control system. The system can monitor and adjust the welding temperature in real time to ensure that the temperature during the welding process remains constant. The application of this technology further improves the welding firmness. The application of these technologies further improves the welding stability of the bag and ensures the tensile strength of the bottom seal.

Gachn group track lamination technology:

In order to avoid bags being broken, powder leakage, and wrinkles caused by bag irregularity during shipment, the discharging mechanism adopts crawler pressing technology. Through the tight pressing of the crawlers, the bottom of the finished bag is smoother and the bag is easier to discharge. Smooth. The application of this technology not only improves the appearance quality of the finished product, but also reduces the irregularity of the packaging.

Gachn group bag unwinding device：

In order to prevent problems such as bag jams and uneven bag tension caused by cloth rolls being too fast or too slow, Gachn Group has uniquely designed a bag unwinding device. It adopts a passive unwinding method, and drives the cloth roll to unwind smoothly through the transportation function of the traction motor. In order to ensure the stability of the tension during the unwinding process of the cloth roll, the device is specially equipped with a magnetic powder braking device, which can effectively control the unwinding speed of the cloth roll.

In terms of tension control, the bag unwinding device adopts a floating tension rod design. The tension can be adjusted according to actual needs and remains constant during operation. This feature ensures the flatness and stability of the material during unwinding. It also ensures the pulling force of the bag and ensures that the valve bag has stable weighing ability when loading minerals.
