Description

Technical Field

[0001] This utility model relates to the field of water-based synthetic leather processing technology, specifically to a water-based synthetic leather foaming device. Background Technology

[0002] With the continuous development of technology, synthetic leather is gradually being used, including water-based polyurethane synthetic leather. Synthetic leather is a plastic product that simulates the composition and structure of natural leather and can be used as a substitute for it. It is usually foamed using foaming agents during the production process. When foaming synthetic leather, foaming equipment is often used. However, when using foaming equipment, it cannot automatically spray the foaming agent and still requires manual operation by the user, which brings inconvenience to the user and can no longer meet the user's needs.

[0003] Among its existing technical patents, such as the authorized announcement number CN221892443U, this utility model discloses a water-based synthetic leather foaming device, including a foaming machine for foaming, a material box fixedly installed on one side of the top of the foaming machine, a cavity opened inside the foaming machine, material rollers movably installed on both sides of the rear surface of the foaming machine via rotating shafts, a material pump fixedly installed at the middle position of the top of the foaming machine, and a spray pipe fixedly installed on one side of the top of the foaming machine. The bottom end of the spray pipe is connected to an atomizing nozzle. This water-based synthetic leather foaming device, by setting rubber rollers, abutment rollers, vibration sensing switches, a material pump, and a spray pipe, enables the device to automatically spray materials during use, eliminating the need for manual operation, greatly improving the efficiency of material foaming, reducing the workload of manual labor, bringing convenience to users, improving the practicality of the device, and meeting the user's needs.

[0004] In the aforementioned patent, a spray nozzle and atomizing nozzle are used for spraying. However, the spray nozzle and atomizing nozzle cannot be moved for spraying. When foaming and spraying, the width of the water-based synthetic leather is very large. When it is processed on an assembly line, the spraying point is fixed, and the spraying is uneven and incomplete. Utility Model Content
