The sofa stuffing machine is used for product filling; it can handle materials such as PP cotton, shredded fabric cotton, fiber cotton, foam beads, crushed sponge, and poultry feathers—soft, loose-fill items—and can evenly blend multiple materials according to your specifications.

The sofa stuffing machine is used for product filling; it can handle materials such as PP cotton, shredded fabric wadding, fiber cotton, foam beads, crushed sponge, and poultry feathers—soft, loose items—and can evenly blend multiple materials according to your specifications. So, do you know how a sofa stuffing machine performs the stuffing process?

The correct method for stuffing cotton into a sofa is as follows:

1. A cotton‑surface height sensor in the fluff storage bin detects the height of the cotton surface; when the height falls below the set threshold, down is replenished into the bin.

2. Verify whether the weighing value of the weighing module is zero; if not, perform a zeroing operation.

3. When the pile height reaches the set value, open the solenoid valve on the air‑delivery pipe during the designated down‑feeding period, allowing the down from the storage bin to be conveyed via high‑pressure air through the pipe into the weighing chamber of the weighing module.

4. Set the wool‑feeding time period; once wool has been fed into the weighing hopper, allow a stabilization period to elapse, then verify the weight reading from the weighing module.

 

 

5. If the weighing module’s measured weight has not reached the preset target value, calculate and perform incremental filling based on the pressure and flow rate of the high-pressure gas in the gas delivery line.

6. Once the filling is complete, allow a stable period to elapse, then verify the weight reading from the weighing module.

7. If the weighing module’s reading reaches the preset weight, it will wait for the fluff-filling command.

8. If the weighing module’s measured value has not yet reached the preset target weight, the process shall continue.

Sofa stuffing machine It serves the same purpose as a cotton‑mixing machine in toy factories, sofa manufacturers, and pillow‑making facilities. Its operating principle involves the central shaft rotating to drive the cotton‑stirring teeth, evenly distributing the cotton into the cotton‑feeding hopper.
