PRODUCT DESCRIPTION

The fully automatic PUR roller coating machine is a glue application device used in production processes. It operates in a fully automated manner, enabling efficient and precise, uniform roller coating of PUR adhesive onto the desired surfaces. It is widely used in the mattress manufacturing industry. The main features of the fully automatic PUR roller coating machine are…

Advantages include:

Efficiency: Fully automated operations can boost production efficiency while reducing labor costs and wasted time.
Precision: Ensures uniform roller coating of adhesive, enhancing product quality and consistency.
Flexibility: The roller coating machine is suitable for products of various sizes and can meet the needs of different customers.
Cost savings: Automated operations reduce the need for manual glue application, thereby lowering glue waste and costs.

Functional Features

1. Water-based adhesives require 24–48 hours to dry; PUR adhesives develop initial tack in 2–3 minutes and can be used directly for subsequent operations, with full curing occurring after 2.5 hours.
The rolls can be compressed directly, eliminating the need for extra storage and drying facilities.
2. PUR adhesive requires a small amount per square meter and boasts extremely high adhesion, reducing costs by roughly 5–6 times compared to water-based adhesives.
3. Water-based adhesives are aqueous fluids that generate significant liquid waste upon use, leading to substantial pollution, whereas PUR hot-melt adhesives are in solid form, more…
It produces little pollution as solid waste.

PUR Hot Melt Adhesive vs. Traditional Water-Based Adhesives

	PUR hot melt adhesive	Water-based adhesive
Drying speed	After applying the adhesive, a certain initial viscosity develops within 2–3 minutes, allowing for direct subsequent cutting and fire‑resistance liner installation. After 2.5 hours, the product can be directly compressed and rolled into packages, creating a complete production line. There is no need for additional warehousing or drying facilities.	The drying process is slow, taking 24–48 hours before the next operation can be carried out.
Water resistance	PUR hot melt adhesive is a moisture-curing, reactive polyurethane hot melt adhesive. When heated, the hot melt adhesive reacts with moisture, giving it far superior water resistance and mold prevention compared to water-based adhesives.	It has poor water resistance; in humid areas, the bonded joints often fail to dry over long periods, and mold may even develop.
Pollutant	PUR hot melt adhesive is in solid form; after cleaning, it mostly becomes solid waste, which is relatively easy to handle.	Water-based adhesives are water‑based fluids that generate a significant amount of liquid waste after use. This liquid waste cannot be discharged directly; instead, it must be treated with dedicated filtration and recovery equipment, otherwise it will lead to serious environmental issues.
Bonding performance	The bond is extremely strong.	General bonding
Economic efficiency	Apply 10–25 g of adhesive per square meter; at a rate of 30 yuan/kg, the cost of adhesive per square meter is approximately 0.3 yuan. For a 2 m × 2 m mattress, the cost of a single layer of sponge is 1.2 yuan. Daily hot melt adhesive expenses amount to 1,200 yuan.	Apply approximately 75 g of adhesive per square meter. At a price of 25 yuan/kg, the cost of adhesive per square meter is about 1.857 yuan. For a 2 m × 2 m mattress with a single layer of foam, the cost is 7.428 yuan. When daily production capacity reaches 1,000 units, daily adhesive costs will amount to 74,280 yuan.
Production and Warehousing	The hot-melt adhesive roller coating method allows for the rapid development of strong initial adhesion after bonding the sponge, enabling processes such as banding and compression rolling. It eliminates the need for dedicated warehousing space, reducing monthly overall costs by 84,000 in unnecessary storage and labor expenses.	When daily output reaches 1,000 pieces and the bed dimensions are 2m × 2m, stacking 7 mattresses per pile requires at least 700–800 square meters of dedicated storage and material handling space for water-based adhesive‑coated foam to cure. Monthly factory rental costs are approximately 2.1 yuan, while 8 warehouse workers are needed for storage, material handling, and transportation, at a rate of 8,000 yuan per worker per month. The total monthly labor cost for storage, handling, and transportation comes to 64,000 yuan, with fixed monthly expenses totaling 85,000 yuan.
Power consumption comparison	The PUR hot-melt roller adhesive machine has a preheating time of approximately 0.5 hours. Calculated at 0.76 yuan per kilowatt-hour, the preheating power consumption is about 48 kW, with preheating electricity costs totaling roughly 18 yuan—normal operation… The operating heating power is approximately 10 kW, with 10 hours of operation per day. Daily electricity costs are about 94 yuan, resulting in monthly electricity expenses of 2,820 yuan. The electricity cost of using hot melt adhesive is… Water-based adhesive costs about 1,000 yuan more.	The water-based adhesive machine has a running power of 8 kW. Calculated at 0.76 yuan per kilowatt-hour, with 10 hours of operation per day, the daily electricity cost is approximately 60 yuan, and the monthly electricity bill comes to 1,000 yuan.
