Spring tube winding machine

Abstract

Disclosed therein is a spring tube winding machine including: a winding roller (10) formed in a cylindrical shape to wind a first rubber sheet (T1), a first code topping paper (C1), a second code topping paper (C2) and a second rubber sheet (T2), which are the spring tube materials, in order, the winding roller (10) including an uneven portion (12) formed on the outer circumferential surface thereof, a nozzle (14) disposed at an end for injecting compressed air, and a plurality of discharge holes (16) for ejecting compressed air injected through the nozzle (14) outwardly from the inside; and a table (20) having a reference line (22) for setting a seating angle in such a fashion that the spring tube materials wound on the winding roller (10) are seated in an unfolded state and the codes (C) embedded in the first code topping paper (C1) and the second code topping paper (C2) are intersected with each other. The spring tube materials are seated at correct positions and wound on the winding roller through the reference lines marked on the table so as to be exactly arranged at the preset code intersection angle, and so, the spring tube winding machine can keep even quality of the spring tube and even buffering force. Moreover, the spring tube winding machine enables the spring tube materials to be easily removed from the winding roller after completion of the stacking and winding process because the discharge hole is formed to spray the compressed air in the outward direction from the inside.
