[patent description] is an automatic leak detector for gloves

[technical field]

The invention belongs to the field of nitrile and latex glove production equipment, and relates to an automatic glove leak detection equipment with automatic control.

Background technology

At present, the main products of plastic glove production line include:7 nitrile, latex gloves, etc.The production line of gloves has two rows (commonly known as single hand mold line) or four rows of hand touch (commonly known as double hand mold line) continuous running production, the running speed is 120-160 ^/ min.

Gloves are divided into surgical gloves, medical examination gloves and industrial gloves according to their USES.As medical-grade gloves, they can only be used as medical-grade gloves after sampling inspection in proportion to check no leakage and meeting the requirements.

The current detection method is to manually remove the gloves in accordance with the sampling inspection ratio, hang the gloves on a special pipe and inject clean water. After 3 minutes, the surface of the gloves is detected to determine whether there is water leakage, so as to define whether the gloves are leaking.After inspection, statistical data are collected to determine whether this batch of gloves meet the requirements for medical use.Due to the time-consuming and laborious traditional leak detection process, the automatic inspection cannot be realized, the inspection accuracy is low, and the inspection results lag behind. Besides, the gloves cannot be used as medical gloves after the water lifting inspection. Especially in the mass production and supply of medical gloves, the amount of gloves consumed for inspection is enough to greatly increase the production cost.Therefore, there is an urgent need for a kind of testing equipment that can automatically and efficiently check the quality of gloves without polluting the gloves and affecting the continued sales and use, so as to meet the current market demand for mass production.
