Abstract
The utility model relates to a bearing formula roller compression roller belongs to a twisting wire drive feed unit who is exclusively used in in the twisting frame. This bearing formula roller compression roller, including lift arm and compression roller, its characterized in that: still include main shaft and bearing. The compression roller of this product makes away the silk smooth and easy naturally in the effect of sending an in -process through the bearing to reach and reduce the yarn strength damage, improve the even rate of the number of turns.
Description
Technical field
The utility model relates to a kind of bearing-type roller pressure roller, belongs to the twisting wire feeder be exclusively used in twisting machine.
Background technology
All also at use iron core roller on existing twisting machine, the situation such as hard draw, strong mill can be produced in wire feed process in actual production process, final result can make yarn strength damaged, the twist is uneven, therefore, need certain technological improvement is carried out for existing roller pressure roller, make it possible to solve the problem.
Utility model content
The utility model object is to provide one to solve the above-mentioned problems in the prior art, can reduce yarn strength breakage, improves the bearing-type roller pressure roller of twist evening ratio.
The utility model object is achieved through the following technical solutions:
A kind of bearing-type roller pressure roller, comprise lift arm and pressure roller, it is characterized in that, also comprise main shaft and bearing, main shaft is through in pressure roller, and pressure roller is provided with bearing, and pressure roller is rotationally connected with on lift arm by main shaft and bearing.
As preferably, also include bearing cover and set bolt, described bearing comprises clutch shaft bearing and the second bearing, described pressure roller towards lift arm while be provided with clutch shaft bearing, another side is provided with the second bearing, bearing cover and set bolt, and described clutch shaft bearing, the second bearing, bearing cover and set bolt are all positioned at pressure roller.
As preferably, described lift arm comprises lift arm and lower lift arm, and upper lift arm narrows gradually to terminal end width, and lower lift arm is U-shaped.
As preferably, described pressure roller is encapsulate pressure roller.
Compared with prior art, the pressure roller of this product makes wire naturally smooth and easy through the effect of bearing in wire feed process, thus it is damaged to reach minimizing yarn strength, improves twist evening ratio.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the exploded view of Fig. 1.
Fig. 3 is the sectional view of pressure roller A-A in Fig. 1.
Label declaration: lift arm 1, upper lift arm 11, lower lift arm 12, pressure roller 2, main shaft 3, clutch shaft bearing 4, second bearing 5, bearing cover 6, set bolt 7.
Detailed description of the invention
Below in conjunction with specific embodiment, the utility model is described, the following example, only for illustration of the technical solution of the utility model, does not limit protection domain of the present utility model.
Embodiment:
As Figure 1-3, the product of the present embodiment comprises lift arm 1, pressure roller 2, main shaft 3 and bearing, and main shaft 3 is through in pressure roller 2, and pressure roller 2 is provided with bearing, and pressure roller 2 is rotationally connected with on lift arm 1 by main shaft 3 and bearing; Lift arm 1 comprises lift arm 11 and lower lift arm 12, and upper lift arm 11 to terminal end width narrows gradually, and lower lift arm 12 is U-shaped, and pressure roller 2 is a kind of encapsulate pressure roller 2.
The present embodiment also includes bearing cover 6 and set bolt 7, bearing comprises clutch shaft bearing 4 and the second bearing 5, pressure roller 2 towards lift arm 1 while be provided with clutch shaft bearing 4, another side is provided with the second bearing 5, bearing cover 6 and set bolt 7, and clutch shaft bearing 4, second bearing 5, bearing cover 6 and set bolt 7 are all positioned at pressure roller 2.
The present embodiment installs main shaft 3 and bearing additional inside original iron core roller pressure roller 2, and do datum mark with pressure roller 2 lift arm 1, by a main shaft 3, bearing is joined at two, and add bearing cover 6, machine operation wire feed process middle roller is sent to retwist ingot position yarn easily by bearing, reaching the breakage of minimizing yarn strength while simple to operation, improving and twisting with the fingers evening ratio.
Particularly, as polyester filament 1000D/3, technological requirement: first twist 380, the sewing thread of retwist 200 or sealing line, about increasing by 5 grams of dawn by bearing pressure roller 2 roller yarn brute force than common iron core pressure roller 2 roller, in twisting unevenness, bearing roller can reach 1.5%, and common iron core pressure roller 2 can only reach 3%.
Be only the specific embodiment of the application above, but the application is not limited thereto, the changes that any person skilled in the art can think of, all should drops in the protection domain of the application.
