Description

Technical Field

[0001] This invention relates to the field of pillow processing technology, specifically to a production apparatus and process for a polyurethane pillow core with jelly balls. Background Technology

[0002] In the textile industry, there are many processes involved in the processing of textiles, which makes the division of labor in this field more detailed. For example, pillows are an essential bedding item for every family's sleep, and they are used and washed very frequently. In the process of processing pillows, the production of pillow cores naturally becomes one of the key points, and the quality of its packaging is also an important factor affecting buyers' desire to purchase.

[0003] The pillow filling materials on the market are diverse, including Chinese medicinal materials such as cassia seeds, wild chrysanthemums, and silkworm excrement; grains such as buckwheat hulls, rice bran, and cotton; and materials such as rush pith, cattail fluff, and waste tea leaves. In addition, materials processed using modern technology, such as porous vacuum cotton, slow rebound sponge, and polyurethane jelly balls, are also widely used filling materials on the market.

[0004] Existing pillow core production equipment cannot support the pillow inner sleeve during filling, resulting in poor filling effect. At the same time, the control of the amount of filling material each time is poor, resulting in different filling amounts of pillow cores, which affects product quality and greatly reduces production efficiency. Therefore, a production device and process for polyurethane pillow cores with jelly balls is proposed to solve the above problems. Summary of the Invention
