Development Prospects and Challenges of the Woven Bag Market

As an important packaging material widely used in agriculture, food packaging, chemical materials and many other fields, woven bags are experiencing stable demand growth, while the requirements for high efficiency and automation in their production process are also constantly increasing.

Market research data shows that the Chinese woven bag machinery market has reached tens of billions of yuan, showing a steady growth trend. From 2016 to 2021, the compound annual growth rate (CAGR) of the Chinese woven bag machinery market reached 7.5%, and the market size is expected to reach hundreds of billions of yuan by 2025.

This growth trend is mainly attributed to the widespread use of woven plastic bags in the packaging industry and the demand for efficient and environmentally friendly production. However, with increasing market competition and stricter environmental requirements, woven bag manufacturers face numerous challenges.

Traditional take-up rollers have significant drawbacks in the feeding process, requiring manual clamping and positioning operations, such as tightening nuts and adjusting clamp positions, to ensure the take-up roller does not shift or wobble during subsequent processing. The entire process is complex and heavily reliant on manual operation, consuming both manpower and time, inevitably slowing down the overall processing pace.

Breakthrough in Intelligent Manufacturing Systems

The newly developed intelligent woven bag processing system offers an innovative solution to the problem of manually locking and limiting the winding rollers.

The system includes components such as a base plate, a support frame, a first drive motor, and a feeding roller. The base plate is fixedly installed on one side of the main body, and the support frame is installed on the top of the base plate. The support frame has first sliding grooves on both sides. A base is installed on the bottom inner side of the support frame, and support seats are installed at both ends of the top of the base. The base has second sliding grooves on both sides.

A connecting rod is slidably connected to the inner side of the second groove, and a top rod is slidably connected inside the two support seats. The bottom of the top rod is fixedly installed on the top of the connecting rod.

The ingenuity of this design lies in the fact that the first drive motor drives the lead screw to connect threadedly inside the moving frame, causing the moving frame to press the limiting seat against the top of the feeding roller, thus clamping and limiting the feeding roller. During feeding, the first drive motor reverses, driving the moving frame to move upward, and through the threaded rod, nut, mounting seat, connecting rod, and push rod, pushes the feeding roller out of the inner side of the support seat.

This makes the operation convenient and quick, eliminating the need for manual locking of the feeding roller, reducing labor costs and increasing subsequent work efficiency.

Revolutionary breakthrough of high-efficiency dual-station production line

The industry's latest 2-in-1 fully automatic multi-functional integrated machine for making plastic woven bags represents a significant improvement in production efficiency. The system includes a main unit, with two outer bag unwinding mechanisms on each side of the main unit, and two inner bag making mechanisms located to the left of one of the outer bag unwinding mechanisms.

On the other side of the main machine, an inner bag pulling mechanism is provided corresponding to each inner bag making mechanism. An inner bag conveying bridge mechanism is provided between each inner bag making mechanism and its corresponding inner bag pulling mechanism. The whole machine adopts PLC and servo control, realizing a high degree of automated production.

This dual-station fully automatic multi-functional machine for ironing inner bags, bagging, and sewing has been successfully tested and can reach a speed of more than 30 bags per minute, which has nearly doubled the production efficiency and completely replaced the original two-in-one plastic woven bag processing machine.

Breakthrough in the research of precision bagging technology for inner membrane bags

In the production of woven bags, the inner lining bag is a crucial step. Because the inner lining bag is very light, when a traditional robotic arm grips the inner lining bag and inserts it into the woven bag, some parts are folded. These folds can form seams due to long-term external pressure. After the material is filled, the seams may rupture due to internal pressure, affecting the waterproof performance of the inner lining bag.

To address this issue, the newly developed composite woven bag processing device incorporates several innovative technologies. The device includes a placement rack, a slide rail, a sliding frame, a push rod, and a clamping head.

The fixing mechanism is fixed to the inner wall of the clamping head. When the electric telescopic rod extends, it smooths the inner film bag inside the woven bag through negative pressure. The adsorption mechanism is fixed to the inner wall of the clamping head, providing negative pressure suction for the fixing mechanism.

An electrostatic mechanism is also fixed to the inner wall of the clamping head, used to drive the adsorption mechanism and generate static electricity. These innovative technologies effectively solve the problem of wrinkles and stretching at the corners of the inner film bag, reduce excessive creases at the corners of the inner film bag, and ensure the sealing of the plastic.

Advantages of automated integrated systems

The most advanced woven bag production equipment has achieved fully automated production. Taking the automatic bagging and sewing machine for plastic woven bags as an example, this equipment uses a servo motor to drive the feeding rollers to automatically feed the fabric, and a servo motor to drive the hot cutting knife to cut the cylindrical fabric, while automatically folding the ends together.

The servo-driven suction slide moves the bag into the automatic inner film bag process. At the same time, the inner film bag is automatically rolled up. The frequency converter controls the geared motor to drive the cloth clamping roller to pull the inner film bag into a roll. The upper and lower heating plates seal the bottom of the inner film bag.

The fabric is then automatically fed by a servo motor-driven feeding roller. The fabric is blown into the cut cylindrical woven bag through upper and lower air inlets and then pulled into the bottom-sewing conveyor belt by the slide table suction port, proceeding to the hemming and bottom-sewing processes. After being conveyed to the automatic flipping and folding bag process, it enters the automatic counting and shifting process. Finally, the counted finished bags are manually collected.

This highly integrated design makes operation convenient, saves time and effort, and has high precision and high yield, greatly improving production efficiency.
