Abstract

The utility model provides a kind of device of adjustable drawing-off roller on spinning preparation machine, and it comprises rocking arm, slide block and holding screw; Be shaped with two gathering sills in the middle part of rocking arm, two gathering sill bottoms are respectively shaped with a rubber roll shaft loose slot for the activity of drawing-off rubber roll shaft; Slide block is shaped with the guide pad of the projection that can be bumped on rocking arm in gathering sill, under guide pad, is shaped with roller position holddown groove; Slide block is arranged in the gathering sill of rocking arm by holding screw and also can moves left and right, fixing after making roller to correct position by adjusting slider, thus realizes the grip hold arc being conducive to sliver quality index.

Description

A kind of device of adjustable drawing-off roller on spinning preparation machine
Technical field
The utility model relates to a kind of device of adjustable drawing-off roller on spinning preparation machine.
Background technology
In spinning preparation machine combing process, 8 drafting of sliver are become web by drafting unit, then through and intersection bundle becomes 1 sliver to export.Drawing-off part adopts the drawing-off mode of corresponding five rollers of three rollers, as shown in Figure 1, drawing-off part roller bottom being arranged in and superposed roller are to the quality of the clamping degree direct influence sliver of web (Fig. 1 middle part lines), wherein two, three rollers are fixed on same rocking arm, two rollers and two, three rollers are tangent, and three rollers and four, five rollers are tangent.Due to the accumulation of part's machining errors and rigging error, two, three rollers can only be tangent with a roller under normal circumstances.As shown in Figure 2, existing roller is arranged in the roller position holddown groove of existing rocking arm bottom, and its installation site is unadjustable, and therefore web cannot form desirable drawing-off grip hold arc in the drafting process of roller and roller, has had a strong impact on the evenness quality of yarn.
Utility model content
The technical problem that the utility model solves: the device providing a kind of adjustable drawing-off roller on spinning preparation machine, to solve the uncontrollable problem in existing roller installation site.
A device for adjustable drawing-off roller on spinning preparation machine, is characterized in that: comprise rocking arm, slide block and holding screw; Be shaped with two gathering sills in the middle part of rocking arm, two gathering sill bottoms are respectively shaped with a rubber roll shaft loose slot for the activity of drawing-off rubber roll shaft; Slide block is shaped with the guide pad of the projection that can be bumped on rocking arm in gathering sill, under guide pad, is shaped with roller position holddown groove; Slide block is arranged in the gathering sill of rocking arm by holding screw and also can moves left and right.
This device of the utility model is made up of two parts, and a part is rocking arm, and another part is slide block.Roller is arranged in the roller position holddown groove on slide block, and this structure can realize the adjustment of roller installation site on rocking arm, thus makes roller can be just tangent with two rollers matched, and realizes the grip hold arc being conducive to sliver quality index in drafting process.Slide block is arranged in rocking arm gathering sill and also can moves left and right, and is processed with roller position holddown groove on slide block simultaneously.Fixing after making roller to correct position by adjusting slider, thus realize the grip hold arc being conducive to sliver quality index.The utility model compared with prior art greatly reduces the problem produced in whole production process, thus realizes the grip hold arc being conducive to sliver quality index.

Detailed description of the invention
Below in conjunction with accompanying drawing 3,4,5, a kind of embodiment of the present utility model is described.A device for adjustable drawing-off roller on spinning preparation machine, is characterized in that: comprise rocking arm 1, slide block 2 and holding screw 3; Be shaped with two gathering sill 1-1 in the middle part of rocking arm 1, two gathering sill 1-1 bottoms are respectively shaped with a rubber roll shaft loose slot 1-2 for the activity of drawing-off rubber roll shaft; Slide block 2 is shaped with the guide pad 2-1 of the projection that can be bumped on rocking arm 1 in gathering sill 1-1, under guide pad 2-1, is shaped with roller position holddown groove 2-2; Slide block 2 is arranged in the gathering sill 1-1 of rocking arm 1 by holding screw 3 and also can moves left and right.Guide pad 2-1 on described rocking arm 1 on gathering sill 1-1 and slide block 2 forms matched in clearance, and fit clearance controls within 0.10mm, and the length of gathering sill 1-1 is compared with the large 3mm of the length of guide pad 2-1.
Operation principle: slide block 2 is arranged in the gathering sill on rocking arm 1, the gathering sill matched in clearance on the guide pad on slide block 2 and rocking arm 1, slide block 2 with rocking arm 1 on can horizontally slip.Drawing-off roller two is arranged in the roller position holddown groove on slide block 2, and the position of adjusting slider 2 just can reach the relative position regulating roller.When the position of adjusting slider 2 makes roller and the roller matched all tangent, be fixed on rocking arm 1 with screw by slide block 2, now drawing-off roller just in time forms desirable grip hold arc with roller, sliver.
