How Do You Filling The Fibers Into Your Pillowcase?

For Small Pillow Filling Machine, pillow processing factories and even plush toy factories, "how to punch fibers into pillowcases" is a core process throughout the entire workshop. Whether it is polyester cotton (PP cotton), feather velvet, seven-hole cotton, or higher-end memory cotton and siliconized hollow cotton, they all need to be loosened, quantitatively measured.

A. Why do we need "punching cotton" instead of "hand filling"?

Efficiency determines output

Traditional manual filling is slow, labor-intensive, and difficult to ensure that the filling amount of each pillow is accurate and consistent. Modern factories generally use the "punching cotton machine" + "quantitative Filling Cotton Machine" automation method to push the fiber into the pillowcase at high speed by air or mechanically. A single machine can complete the punching and filling of 5-10 pillows per minute, greatly increasing production capacity.

Consistency ensures quality

For home textile brands and OEM factories, batch products must meet the three requirements of "same fluffiness, same weight, and same feel". With the help of Quantitative Cotton Filling Machines, electronic weighing modules and other equipment, the fiber weight can be accurately controlled every time, and the "consistent weight" and "consistent looseness" are achieved to the extreme when flushing into the pillowcase.

Improve the workshop environment

During manual Pets House Fiber Filling Machine, a large amount of fiber dust fills the workshop, which not only affects the health of employees, but also easily causes waste of raw materials and difficulty in cleaning the workshop. The closed cotton flushing system transports the fiber to the pillowcase along the pipeline, reducing dust and keeping the workshop clean.

B. Introduction to key equipment Polyester Pillow Filling Machine

1. Fiber Opener

Before "flushing cotton", the original cotton wool (polyester cotton, feather velvet, seven-hole cotton, etc.) must be opened first. The functions of the opener are:

Disintegration: Break up the compressed cotton wool to make the fibers loose and fluffy;

Combing: Remove dust and impurities through multi-stage rollers and beater structures, and make the fibers evenly distributed;

Preliminary mixing: If different batches or different types of fibers are to be mixed, the built-in mixing function of the opener can achieve preliminary uniformity.

The fibers obtained after opening have high fluffiness and no large entanglements before entering the next step of quantitative weighing.

2. Quantitative Filling Machine (quantitative weighing module)

The "quantitative filling machine" can also be called "pillow fiber weighing machine" or "quantitative weighing machine", which is the core of the entire cotton punching process:

Electronic weighing: The error of the weighing sensor can be controlled within ±1-3 grams, and the fiber weight in the bin is monitored in real time;

Volume/weight dual measurement: Some high-end models are also equipped with volume sensors, which combine volume and weight dual calibration to improve measurement accuracy;

Automatic zeroing and circulation: After each filling, it automatically resets to zero, cleans up residual fibers, and enters the next weighing cycle.

Accurate weighing makes the filling weight of each pillow basically the same, avoiding the situation of "some are too hard and some are too soft".

3. Pneumatic cotton punching system Pp Cotton Filling For Pillow Pets Machine

The fibers that have been loosened and quantitatively input into the pillowcase are usually pneumatically punched. The specific components include:

High-pressure fan or vacuum fan: Provides a stable air source, "sucks" the fiber up through the pipeline, and then "blows" it into the pillowcase;

Transmission pipeline: Wear-resistant, electrostatically treated pipes to reduce fiber adhesion, the pipe diameter is generally φ50-φ100 mm;

Switch valve/diverter valve: If one fan serves multiple quantitative machines, the solenoid valve automatically controls the cotton delivery line to accurately distribute the fiber;

Cotton flushing gun or nozzle: According to the size and structure of the pillowcase opening, choose cotton flushing nozzles of different shapes to allow the fiber to enter evenly and quickly.

Pneumatic cotton flushing can inject quantitative fibers into the pillowcase within 1-3 seconds, with simple operation and a production cycle of up to 10 pieces/minute.

4. Control system Fibre Pillow Filling Machine Price

Modern cotton punching lines are generally equipped with PLC + touch screen, which can achieve:

Multiple sets of program presets: According to different pillowcase specifications (size, bag opening position), preset corresponding cotton punching parameters (wind pressure, time, weighing target);

Real-time monitoring and alarm: When the weighing error exceeds the standard, the pipeline is blocked or there is a lack of material, it will automatically alarm and stop the machine to reduce the defective rate;

Production line linkage: Quilt Fiber Filling Machine can be interconnected with upstream and downstream equipment such as openers and packaging machines to form a one-stop automated production line.

C. Process flow of fiber punching into pillowcases Filling Machines For Stuffed Toys

The following is the main line of "opening → quantitative weighing → pneumatic cotton punching" to sort out the specific steps.

Raw material warehouse delivery and opening

The operator puts the packaged cotton wool (PP cotton, feather velvet, etc.) into the opener bin

After the opener is started, the fiber is torn loose by the beater roller, and the vibrating screen removes impurities and dust.

After opening, the fibers flow into the transfer bin (or directly into the quantitative module)

If the opener and the quantitative filling machine are independent, the loose fibers need to be transported to the quantitative bin;

If the two devices are linked, the opened fibers can be directly sent to the quantitative bin by spiral feeding or pneumatic conveying.

Quantitative weighing and dosing Pp Cotton Filling Machine

On the quantitative filling machine, set the weighing target (such as 500 g±3 g) according to the product specifications;

After the program is started, the system automatically feeds, and when the weighing module shows that the target weight has been reached, the feed valve is automatically closed.

Pneumatic cotton flushing Machine For Stuffing Pillows

Open the nozzle switch of the cotton flushing gun, and the high-pressure airflow instantly injects the quantitative fiber into the pillowcase through the nozzle;

According to the pillowcase size and filling requirements, the operator can swing the nozzle left and right to ensure that the fibers are evenly distributed.
