The broad-adjustable bar-guiding device of a kind of drawing frame
Technical field:
The present invention relates to drawing frame technical field, more specifically to the broad-adjustable bar-guiding device of a kind of drawing frame.
Background technology:
The effect of drawing frame is the internal structure improving strip, thus improves its long segment uniformity, reduces weight unevenness simultaneously, make the straightening of fibers in strip parallel, reduce crotch, fineness is conformed with the regulations, the raw material of variety classes or different quality is mixed evenly, reaches the mixing ratio of regulation.But there is a certain distance between the width of the sliver of some pending draftings, so a guide strip rack generally can be provided with to process the stand out of sliver on drawing frame, but spacing between the every root guide rod on traditional guide strip rack manually operation adjustment, and the spacing adjustment carried out between every root guide rod is consuming time longer, operation is also inconvenient.
Summary of the invention:
Object of the present invention is exactly the deficiency for prior art, and provides a kind of drawing frame broad-adjustable bar-guiding device, and it is convenient to operation, can distance between all guide rods of disposable adjustment.
Technology solution of the present invention is as follows:
The broad-adjustable bar-guiding device of a kind of drawing frame, comprise base, base is fixed with support column, the upper end of support column is bolted to connection horizontal gripper shoe, gripper shoe is welded with rail brackets, the left side of rail brackets forms the conduit of concave shape, the conduit of described rail brackets is inserted with some connected voussoirs, voussoir is plugged with guide rod, the voussoir of described low order end is fixed on rail brackets, the voussoir of high order end is connected on contiguous block, the other end of contiguous block is plugged with push rod, the left end of push rod forms external screw thread and passes limited block, limited block is welded in gripper shoe 3, runner is provided with in described limited block, runner is screwed onto on push rod,
Described voussoir comprises square and T-shaped piece of composition, the upper end of square forms T-shaped piece, the upper end of T-shaped piece forms screwed hole, the front of described square forms the groove of concave shape, the upper side of groove forms rectangular recess, the back side of square forms ring-like boss, and described guide rod is plugged on ring-like boss; T-shaped piece of sleeve of one voussoir of described two adjacent voussoirs, in the groove of another voussoir, is provided with spring between two voussoirs, and spring one end sleeve is in T-shaped piece of screwed hole of voussoir, and the other end of spring is pressed against on the upper side wall of another voussoir rectangular recess; Described contiguous block) comprise square main body, the side of main body forms T-shaped split, and the side of the described main body relative with split forms circular hole, and push rod is plugged on the circular hole of contiguous block; The Split plugging of described contiguous block is enclosed within the groove of voussoir.
Outer wall on described push rod forms the thin trace of annular, the gripper shoe on rear side of thin trace is fixed with scale.
The outer wall of described runner is evenly distributed with some slotted eyes.
Beneficial effect of the present invention is:
It utilizes screw thread to realize moving left and right of promotion, thus realize the compression variation of spring on voussoir, make the spacing between the guide rod on voussoir carry out a shape adjustment, it is convenient to operation, the preparation run for drawing frame saves the time, thus improves production efficiency.

Detailed description of the invention:
Embodiment: as shown in Figure 1, the broad-adjustable bar-guiding device of a kind of drawing frame, comprise base 1, base 1 is fixed with support column 2, the upper end of support column 2 is bolted to connection horizontal gripper shoe 3, gripper shoe 3 is welded with rail brackets 4, the left side of rail brackets 4 forms the conduit of concave shape, the conduit of described rail brackets 4 is inserted with some connected voussoirs 5, voussoir 5 is plugged with guide rod 7, the voussoir 5 of described low order end is fixed on rail brackets 4, the voussoir 5 of high order end is connected on contiguous block 6, the other end of contiguous block 6 is plugged with push rod 9, the left end of push rod 9 forms external screw thread 9a and passes limited block 8, limited block 8 is welded in gripper shoe 3, runner 10 is provided with in described limited block 8, runner 10 is screwed onto on push rod 9,
Described voussoir 5 comprises square 5a and T-shaped piece of 5d composition, the upper end of square 5a forms T-shaped piece of 5d, the upper end of T-shaped piece of 5d forms screwed hole 5e, the front of described square 5a forms the groove 5b of concave shape, the upper side of groove 5b forms rectangular recess 5c, the back side of square 5a forms ring-like boss 5f, described guide rod 7 is plugged on ring-like boss 5f; T-shaped piece of 5d sleeve of one voussoir 5 of described two adjacent voussoirs 5 is in the groove 5b of another voussoir 5, spring 11 is provided with between two voussoirs 5, spring 11 one end sleeve is in T-shaped piece of 5d screwed hole 5e of voussoir 5, and the other end of spring 11 is pressed against on the upper side wall of another voussoir 5 rectangular recess 5c; Described contiguous block) comprise square main body 6a, the side of main body 6a forms T-shaped split 6b, the side of the described main body 6a relative with split 6b forms circular hole 6c, push rod 9 is plugged on the circular hole 6c of contiguous block 6; The split 6b sleeve of described contiguous block 6 is in the groove 5b of voussoir 5.
Outer wall on described push rod 9 forms the thin trace 9b of annular, the gripper shoe 3 on rear side of thin trace 9b is fixed with scale 12.
The outer wall of described runner 10 is evenly distributed with some slotted eye 10a.
Operation principle: the present invention rotates by the slotted eye 10a that rod is inserted in runner 10, thus drives moving left and right of push rod 9, realizes the length variations of spring 11 between voussoir 5, thus achieves the adjustable of the distance between voussoir 5 guide rod.And spring 11 is all identical springs 11 between voussoir 5, the deflection of its forced compression is all identical, all when spring 11 is out of shape, and between its all voussoir 5, spring 11 length is identical, so the spacing between two adjacent guide 7 is also identical.
