In the prior art, Authorization Notice No. is the Chinese patent of CN203080150U, discloses a kind of drawing frame.It includes
Feeding unit, drafting system and at strip device, are successively installed.Feeding unit have carriage, cotton cylinder material position in carriage in the following,
Shunting handle is installed on carriage.It is arranged in this way, so that the orderly smooth entrance drafting system of the carded sliver.
But in the utility model, after sliver passes through the slitting of shunting handle, enters on carriage, be easy to cause yarn
Item is not bonded with carriage.
Utility model content
The purpose of this utility model is to provide a kind of drawing frames, have and are bonded sliver with carriage, are readily transported
Advantage.
The above-mentioned purpose of the utility model has the technical scheme that
Setting before and after a kind of drawing frame, including feeding unit and drafting system, the feeding unit and the drafting system,
It is provided with conveying mechanism on the feeding unit, is provided with shunting handle along the conveying direction of sliver on the conveying mechanism,
The more vertical bars that the shunting handle includes cross bar and is vertically connected on cross bar side by side, be provided with above the shunting handle with
The parallel pressing roller of the cross bar.
Implement above-mentioned technical proposal, when more slivers convey on the conveyor, more slivers pass through shunting hand respectively
The channel that handle cross tube and vertical bar are formed is fed forward, and is reduced more slivers and is not separated showing of can winding when being fed forward
As, while when sliver conveys in the channel on the handle of shunting, in the case where sliver tensile force is inadequate, sliver and conveying
Frame is easy not to be bonded with carriage, sliver is pushed down by pressing roller, so that sliver is adjacent to carriage, preferably to pass through conveying
Frame conveys sliver.
Further, the conveying mechanism includes support frame and conveying roller on the support frame arranged side by side, the shunting hand
Handle connects on the support frame, and the conveying roller is arranged in front of conveying sliver direction in the shunting handle and the pressing roller
Side.
Implement above-mentioned technical proposal, after sliver avoids winding by shunting handle shunting, then pass through pressing roller to sliver into
After row tensioning so that sliver fits with conveying roller, to transport, reduction sliver be not tensioned be not bonded with conveying roller when, yarn
Item can not be the case where being fed forward on conveying roller.
Further, the cross bar is rotatably connected to cursor far from one end of support frame as described above, and the cursor is far from institute
The one end for stating cross bar is connect with the pressing roller.
Implement above-mentioned technical proposal, pressing roller is connect by cursor with cross bar, and cursor and cross bar are rotatablely connected, so that
Pressing roller can compress sliver by the rotation of pressing roller to adjust, so that sliver and conveying roller according to the tensioning degree of sliver
It fits.
Further, the shunting handle is provided with screw rod far from one end of support frame, and the cross bar is fixed with the screw rod
Connection, the cursor are socketed on the screw rod, and the nut for pushing against cursor is threaded on the screw rod.
Implement above-mentioned technical proposal, cursor is socketed on screw rod and is freely rotated, and cursor turns to pressing roller properly
When on position, by tightening on the cross bar that cursor is pushed against on the handle of shunting by nut, so that the position of pressing roller is fixed, with
Just sliver is preferably compressed.
Further, turning handle is provided on the nut.
Implement above-mentioned technical proposal, by being provided with turning handle on nut, conveniently nut is tightened or unscrews by turning handle.
Further, strut in front of the conveying roller and parallel with the conveying roller, institute are provided on support frame as described above
It states strut and one end of support frame as described above is provided with conducting bar hole.
Implement above-mentioned technical proposal, have sliver cylinder below conveying roller, sliver is placed in sliver cylinder, and sliver is logical from sliver cylinder
It crosses conducting bar hole to enter on conveying roller, sliver is facilitated to be bonded with conveying roller, so as to sliver transport.
Further, one layer of anti-static coating is covered on the conveying roller.
Implement above-mentioned technical proposal, be provided with anti-static coating by covering on conveying roller, reduces sliver by defeated
When sending roller, the short flannel on sliver is adsorbed on pressing roller and conveying roller.
Further, being arranged side by side on the drafting system has more follower arms.
Implement above-mentioned technical proposal, there are more follower arms by being arranged side by side on drafting system, so that sliver passes through phase
The channel that two adjacent follower arms are formed passes through, and there is a phenomenon where wind when avoiding a plurality of sliver together into figure drafting system.
In conclusion the utility model has the following beneficial effects:
One, in the case where sliver tensile force is inadequate, sliver is easy not to be bonded with carriage with carriage, passes through pressing roller
Sliver is pushed down, so that sliver is adjacent to carriage, preferably to convey sliver by carriage;
Two, pressing roller connect by cursor with cross bar, cursor and cross bar rotation connection, allow pressing roller according to
The tensioning degree of sliver compresses sliver by the rotation of pressing roller to adjust, so that sliver fits with conveying roller；
Three, be provided with anti-static coating by covering on pressing roller and conveying roller, reduce sliver by pressing roller and
When conveying roller, the short flannel on sliver is adsorbed on pressing roller and conveying roller.

Support frame 31 and more conveying rollers 32 being disposed side by side on support frame 31 are covered with one layer of anti-static coating on conveying roller 32
12, in the present embodiment, anti-static coating 12 is polyurethane coating, and a sliver cylinder is corresponding with below every conveying roller 32.
In conjunction with Fig. 2 and Fig. 3, shunting handle 4 is welded on carriage along the conveying direction of sliver, shunting handle 4 includes
Cross bar 41 and four vertical bars 42 being vertically welded on cross bar 41 side by side.It is provided with above shunting handle 4 parallel with cross bar 41
Conveying roller 32 is arranged in along the front in conveying sliver direction in pressing roller 5, shunting handle 4 and pressing roller 5.Cross bar 41 is far from support frame
31 one end is rotatably connected to cursor 6, and the one end of cursor 6 far from cross bar 41 is fixedly connected with pressing roller 5.Cross bar 41 is along it
Length direction is welded with screw rod 7 at its end, and cursor 6 is socketed on screw rod 7, is threaded on screw rod 7 and turns for pushing against
The nut 8 of swing arm 6 is welded with the turning handle 9 for rotating nut 8 on nut 8.
In conjunction with Fig. 2 and Fig. 3, it is provided on support frame 31 in 32 front of conveying roller and the strut parallel with the conveying roller 32
10, strut 10 is welded with the conducting bar hole 11 of taper far from one end of support frame 31.
Specific work process: sliver is entered on conveying roller 32 from sliver cylinder by conducting bar hole 11, and sliver enters down
When on one conveying roller 32, initially pass through will be entered simultaneously in the cavity that cross bar 41 and vertical bar 42 on shunting handle 4 are formed it is defeated
It send a plurality of sliver on roller 32 to be separated, them is avoided to wind.Further according to the sliver conveyed on each conveying roller 32 whether with
It is adjacent to, then by cursor 6 rotate pressing roller 5 so that sliver be tensioned so that sliver during transportation with conveying roller
32 are adjacent to.Nut 8 is turned by turning handle 9 again, cursor 6 is pushed against on the cross bar 41 of shunting handle 4, its position is fixed.It is more
Sliver is entered in drafting system 2 under the drive of conveying roller 32 by the separation of follower arm 13.
