Description
Technical field
The utility model relates to textile industries, it particularly relates to a kind of variable-ratio drawing frame.
Background technique
The effect of drawing frame is to improve the internal structure of strip, to improve its long segment uniformity, while reducing weight
Irregularity keeps the straightening of fibers in strip parallel, reduces crotch, fineness is made to meet regulation.In weaving variety classes or different product
The raw material of matter is mixed evenly, and needs to set different weaving speed, and existing common method is the attached with frequency converters on motor, at
This is higher.
For the problems in the relevant technologies, currently no effective solution has been proposed.
Utility model content
For above-mentioned technical problem in the related technology, the utility model proposes a kind of variable-ratio drawing frames, can.
To realize the above-mentioned technical purpose, the technical solution of the utility model is achieved in that
A kind of variable-ratio drawing frame, including rack, the upper end of the rack is equipped with material guide mechanism and hold-down mechanism, described
The bottom of rack is provided with material collecting barrel；The hold-down mechanism includes the first roller and second of arranged side by side and synchronous backward rotation
Roller is additionally provided with the motor for driving the first roller rotation in the rack；The first roller is connected with conical drum,
The motor is connected with the disk with conical drum rotation connection；Slideway is additionally provided in the rack, the motor is sliding
Move on the slideway and the disk always with the conical drum be rotatablely connected, the motor, which is additionally provided with locking system, to be made
The motor is fixed on the slideway.
Further, cleaning vacuum plant is provided at the first roller and second roller.
Further, second roller is provided with spring pressuring.
Further, the conical drum surface is rough surface.
Further, the disc surfaces are rough surface.
The utility model has the beneficial effects that the utility model changes the position change disk of motor by slideway and taper is rolled
The contact point of cylinder to change the transmission ratio of disk and conical drum to adjust the revolving speed of first roller, and then adjusts drawing frame
Drafting speed.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Needed in attached drawing be briefly described, it should be apparent that, the accompanying drawings in the following description is only the utility model
Some embodiments for those of ordinary skill in the art without creative efforts, can also be according to this
A little attached drawings obtain other attached drawings.
Fig. 1 is the structural schematic diagram of variable-ratio drawing frame.
In figure: 1. racks, 2. material collecting barrels, 3. first rollers, 4. second rollers, 5. motors, 6. conical drums, 7. disks,
8. slideway.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art's every other embodiment obtained, all belongs to
In the range of the utility model protection.
As shown in Figure 1, according to a kind of variable-ratio drawing frame of the utility model embodiment, including rack 1, rack 1 it is upper
End is equipped with material guide mechanism and hold-down mechanism, and the bottom of rack 1 is provided with material collecting barrel 2；Hold-down mechanism includes arranged side by side and same
Counter-rotational first roller 3 and the second roller 4 are walked, the motor 5 for driving first roller 3 to rotate is additionally provided in rack 1；First
Roller 3 is connected with conical drum 6, and motor 5 is connected with the disk 7 being rotatablely connected with conical drum 6；Cunning is additionally provided in rack 1
Road 8, motor 5 slides on slideway 8 and disk 7 is rotatablely connected with conical drum 6 always, and motor 5, which is additionally provided with locking system, to be made
Motor 5 is fixed on slideway 8.
In a specific embodiment of the utility model, vacuum cleaning is provided at first roller 3 and the second roller 4
Device.
In a specific embodiment of the utility model, the second roller 4 is provided with spring pressuring.
In a specific embodiment of the utility model, 6 surface of conical drum is rough surface.
In a specific embodiment of the utility model, 7 surface of disk is rough surface.
In order to facilitate the above-mentioned technical proposal for understanding the utility model, below by way of practical new to this in specifically used mode
The above-mentioned technical proposal of type is described in detail.
When specifically used, a kind of variable-ratio drawing frame according to the present utility model adjusts position of the motor 5 on slideway 8
It sets, is then fixed on motor 5 on slideway 8 with locking system.When butt end of the disk 7 close to conical drum 6, transmission is compared
Small, drawing frame speed is slower.When taper end of the disk 7 close to conical drum 6, it is driven bigger, drawing frame fast speed.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection scope within.
