Abstract
The utility model relates to a press bar of an up-lap-guard attack area used for a ring spinning frame. The structure of the utility model is that the portion of the press bar positioned at the front end of the lower rim of an upper pin spring block of an upper pin body is produced into a block-typed bar body after being installed, and the cross section of the block-typed bar body is in the formation that the front-lower end is in the shape of a circular arc and the rear upper end is in the shape of a sharp corner which is slantingly up-warping. After installing the press bar on the upper pin body of draft zone of the spinning frame, a slantingly up-warping baffle which faces the forward motion direction of a fiber strand is arranged on the barred body portion of a baffle plate, thereby effectively preventing partial fiber in the fiber strand from winding up and forcing the fiber strand to pass through the bottom of the press bar successfully, thus not only distribution uniformity of friction field in the draft zone can be controlled effectively to ensure the effect of curve drafting, but also the splitting of the fiber strand can be avoided and the quality of spinning evenness can be improved obviously.
Description
Technical field
The utility model relates to the parts on a kind of ring throstle, specifically a kind of anti-going up around the proparea pressure bar.
Background technology
In the spinning process of ring throstle, yarn is by the draw zone between forward and backward roller the time, wherein Jue Daduoshuo fiber is pressed the speed motion of front roller again after instantaneous speed change on a certain cross section, but minority fiber, it mainly is the part staple fibre, each speed change is instantaneous finishing, and has repeatedly rapid change at draw zone.This just makes the speed change point of fiber head end disperse, and causes the changeable of fiber movement, has increased the inhomogeneities of resultant yarn thus.For improving yarn quality, people are provided with the pressure bar of a horizontal before the shank on draw zone, and pressure bar is in the front end of shank spring of top apron cradle piece.Pressure bar is pressed on the yarn during work, and yarn is played a kind of boundling effect, also forces yarn to produce certain bending simultaneously.Like this, both reached the effect of curve drawing, and increased the grip hold arc length of yarn and front roller simultaneously again, the distributing homogeneity of draw zone friction field is strengthened, yarn quality improves.Therefore the use of ring throstle draw zone pressure bar is more and more universal.But, when the pressure bar compressing makes the yarn bending, yarn for some raw material that passes through draw zone, the fiber that has part is not normally to pass through from the below of pressure bar, but, promptly formed the yarn split around the top of having arrived pressure bar, the spun yarn bar that is spun is done interrupted, will form a joint fault after connecting, influence one-tenth cloth quality afterwards.
The utility model content
The purpose of this utility model just provides a kind of not only can bring into play curve drawing effect, but also anti-the going up around the proparea pressure bar that can avoid yarn split phenomenon to take place.
The utility model is achieved in that anti-going up around the proparea pressure bar is that pressure bar is made for baffle plate shape barred body in this part that is in shank spring of top apron cradle piece lower edge front end behind the dress, and the cross section of this baffle plate shape barred body part is that preceding lower end is that circular arc, upper end, back are the forms of the oblique pointed shape that upwarps.After this pressure bar being installed on the last shank of ring throstle draw zone, the barred body part of its baffle plate shape has an oblique baffle plate that upwarps owing to face the forward motion direction of yarn, thereby stoped going up of part fiber in the yarn effectively, forced the yarn all successfully to pass through from the below of pressure bar around situation.Like this, use of the present utility model both can have been controlled the distributing homogeneity of draw zone friction field effectively, had guaranteed the effect of curve drawing, had avoided the generation of yarn split phenomenon again simultaneously, thereby the quality that the spinning bar is done significantly improves.
Below in conjunction with accompanying drawing the utility model is further described.

Fig. 2 is the cross sectional representation of the utility model baffle plate shape barred body part.
Fig. 3 is the structural representation of another implementation of the utility model.
The specific embodiment
Embodiment 1:
As shown in Figure 1, the anti-pressure bar of going up in the pressure bar of proparea 1 of present embodiment is a long and thin metal straight-bar, baffle plate shape barred body 2 is set on the both sides of pressure bar 1, the stage casing of pressure bar 1 is plugged in the preformed hole of spacing block 4, respectively the peg graft baffle plate 3 of a metal or nonmetal system of the both sides of pressure bar 1 constitutes baffle plate shape barred body 2.As shown in Figure 2, the cross section of baffle plate shape barred body 2 is that preceding lower end is that circular arc, upper end, back are the oblique pointed shape that upwarps.
After the spacing block 4 with pressure bar 1 middle part was loaded on shank, the baffle plate shape barred body 2 on pressure bar both sides just in time was in the front end of shank spring of top apron cradle piece lower edge, with this can stop effectively part fiber in the yarn 5 go up around.
Embodiment 2:
As shown in Figure 3, anti-the going up around the proparea pressure bar of present embodiment is a bending bar, baffle plate shape barred body 2 is arranged on one side of pressure bar 1, the another side of pressure bar 1 is the right angle bending section, the end of this right angle bending section can directly be plugged on the shank, make baffle plate shape barred body 2 be in the front end of a spring of top apron cradle piece lower edge on the shank, with this can stop effectively part fiber in the yarn go up around.
Certainly adopt this structure, will be on same the both sides of the spacing block of shank respectively peg graft on opposite be provided with anti-around the proparea pressure bar.
In the present embodiment, can also can singly do a baffle plate 3, be plugged into again on the pressure bar 1 of round bar shape, formation baffle plate shape barred body 2 with metal or nonmetallic materials with baffle plate shape barred body 2 and pressure bar 1 whole machine-shaping as embodiment 1.
As shown in Figure 2, the cross section of the baffle plate shape barred body 2 in the present embodiment also is that preceding lower end is that circular arc, upper end, back are the oblique pointed shape that upwarps.
The utility model also can be equipped with or prepare overhead gage mechanism on other known or unknown parts that play the pressure bar effect, go up around the proparea pressure bar around the anti-of situation on the part fiber to constitute to stop in the yarn.
Claims (3)
1. prevent going up around the proparea pressure bar for one kind, the part that it is characterized in that being in behind pressure bar (1) dress shank spring of top apron cradle piece lower edge front end is a baffle plate shape barred body (2), and the cross section of this baffle plate shape barred body part is that preceding lower end is to be the oblique pointed shape that upwarps on circular arc, the back.
