Description

TECHNICAL FIELD

[0001] The utility model belongs to glove demolding technical field, and specifically is a powder-free demolding agent spraying device for nitrile glove. BACKGROUND

[0002] Nitrile gloves are widely used in medical, laboratory and industrial fields due to their excellent chemical resistance, puncture resistance and biocompatibility. In the traditional glove production process, talcum powder or corn starch is usually used as a release agent to prevent glove adhesion and facilitate wearing. However, these powders are prone to residue, which may cause user allergies or environmental pollution. Therefore, powder-free demolding technology has become an industry trend, and spraying liquid release agents (such as silicone oil emulsion or polymer coating) is currently the mainstream solution.

[0003] However, the spraying process of powder-free release agent still faces significant challenges. Uneven spraying is one of the core problems, as traditional release agent spraying devices are generally arranged at the top, which can result in uneven coating thickness on the glove surface, with some areas sticking and other areas affecting the touch due to excessive spraying. In addition, the lack of precision in the spraying system also leads to waste of release agent, increasing production costs. Release agents are generally expensive, and excessive spraying or ineffective use of the agent directly increases raw material waste; at the same time, uneven coating can also lead to an increase in defective products, further amplifying cost pressure.
