Doffer spool case
Technical field
The utility model relates to a kind of doffer spool case.
Background technology
At present, there is a kind of doffer not only can take out, and empty spool can be inserted on the spindle, promptly can finish tube drawing and intubate work twining full spool on the fine spining machine.There is the spool case of placing empty spool this doffer top, has the spool outlet in the middle of the spool case bottom, and spool falls into the Intubaction device of below through this outlet.Because spool two ends thickness is inhomogeneous, the upper end of spool is thin, the lower end is thick, gap in storing the spool case of spool between the thin end is bigger, and the gap between the butt end is little, in case the spool of below falls behind down, the spool of top and both sides thin end mutual extrusion in the process that falls can cause spool to tilt and stop up the spool outlet, must be after artificial auxiliary cleaning could normal descend, so operating personnel's operational ton is still bigger.
Summary of the invention
The purpose of this utility model is at the deficiencies in the prior art part, and a kind of doffer spool case is provided, and spool is difficult for stopping up the spool outlet, the artificial little advantage of auxiliary operation amount.
For achieving the above object, the utility model has adopted following technical scheme: have the spool outlet in the middle of the spool box plate, it also comprises a tube pulling unit, described tube pulling unit is by the tube pulling sheet, turning cylinder, cursor and draw-gear are formed, spool exports and has the through hole that passes through for turning cylinder on the base plate of a side, turning cylinder is located on the spool box plate by through hole and axle sleeve vertical rack, the tube pulling sheet is fixed on the turning cylinder of spool box plate top, the tube pulling sheet movable end moving axis that can rotate rotates to spool outlet top and covers the spool outlet, cursor is connected on the turning cylinder of spool box plate lower end, the cursor other end and reciprocating draw-gear hinge.
Draw-gear drives cursor and does intermittent motion, make the tube drawing sheet moving axis that rotates do gap swing, after tube drawing sheet movable end goes to the outlet top, the spool that is tilted in the outlet top is unpluged, spool is arranged neat under the effect of deadweight again, every swing is once promptly cleared up once outlet, thereby can substitute artificial periodic cleaning spool outlet.
A preferred version of the present utility model is: be positioned at the tube pulling sheet outer side edges that spool exports a side and be arranged in parallel at initial position and spool outlet.The tube drawing sheet under static state, when the exit fell, can whole move, and can not cause its inclination by the spool two ends by tube drawing sheet outer side edges for spool, the tube drawing sheet is little to the spool influence of falling.
Owing to adopted above-mentioned technical solution, make the utility model can effectively solve the problem that spool is blocked outlet spout, and volume is little, required drive is little, and is easy for installation, easy operating; And pipe drawing device is simple in structure, and moulding is easy, makes can reduce artificial input when automated production, can reach the automation target that reduces cost, improves output.

The specific embodiment
As depicted in figs. 1 and 2, the utility model spool case 1 is placed on the support 2 on the doffer, have spool outlet 12 in the middle of spool case 1 base plate 11, tube pulling unit is by tube pulling sheet 3, turning cylinder 5, cursor 6 and draw-gear are formed, draw-gear is a telescopic cylinder 7, spool exports and has the through hole that passes through for turning cylinder 5 on the base plate 11 of 12 1 sides, turning cylinder 5 is located on spool box plate 11 and the support 2 by through hole and axle sleeve 4 vertical racks, tube pulling sheet 3 is fixed on the turning cylinder 5 of spool box plate 11 tops, being arranged in the tube pulling sheet outer side edges 31 that spool exports 12 1 sides is that Fig. 2 dotted portion present position and spool outlet 12 be arranged in parallel at initial position, and the tube pulling sheet 3 movable ends moving axis 5 that can rotate rotates to spool and exports 12 tops and cover spool outlet 12.Cursor 6 is connected on the turning cylinder 5 of spool box plate 11 and support 2 lower ends, and the piston rod of cursor 6 other ends and telescopic cylinder 7 71 is hinged, and telescopic cylinder 7 is fixed on the doffer and communicates with gas control device on the doffer.
During tube drawing, as shown in Figure 3, the piston rod 71 of telescopic cylinder 7 drives cursor 6 and does intermittent motion, make tube drawing sheet 3 moving axis 5 that rotates do gap swing, after tube drawing sheet 3 movable ends go to outlet 12 tops, the spool 8 that is tilted in the outlet top is unpluged, spool 8 is arranged neat under the effect of deadweight again, every swing is once promptly cleared up once outlet, thereby can substitute artificial periodic cleaning spool outlet.
