The invention discloses a spun
yarn waxing device used for
spinning and capable of preventing
yarn breakage and relates to the technical field of spun
yarn waxing. The device comprises an anti-slidingblock and a first connecting rod, a support block is mounted above the anti-sliding block, a base is arranged above the support block, and vent holes are formed in the outer side of the base. A fixing block, an air cylinder, a
piston, a straight rod, an ejector rod, a casing, a hydraulic rod and a
wax groove are arranged in the spun yarn
waxing device used for
spinning and capable of preventing yarn breakage, a user can fix the air cylinder above the base through the fixing block, the user can slide the
piston up and down in the air cylinder, the
piston can well support the straight rod, thestraight rod can well support the ejector block, then, during use, the hydraulic rod can drive the
wax groove to
telescope upwards with reduction of a
wax block so as to enable the wax block to make contact with spun yarn, the user can use the device conveniently, non-uniform waxing of the spun yarn due to reduction of the wax block can be well avoided, and the
processing quality of the device isenhanced.
