Abstract
The invention discloses a mechanism with double beams for an air-jet loom. The mechanism comprises a clamp ring, a fixed beam, a support capable of moving horizontally, a movable beam, and a movable beam holding bracket, wherein the movable beam holding bracket is connected to the support capable of moving horizontally; the movable beam is directly mounted in the internal cavity with an open end in the movable beam holding bracket; bearings are mounted at two ends of the fixed beam, tightly matched with the clamp ring and directly placed in semicircular devices of the support capable of moving horizontally. Due to the adoption of the invention, the wrap angle of warp yarn stays the same on the tension axis while the diameter size of loom beam changes and a pressure angle between the two beams remains unchanged, so that the mechanism keeps the tension stability of warp yarn, which improves the efficiency of the loom and ensures the high-speed rotation of the loom.
Description
Technical field
The present invention relates to the air-jet loom field, especially relevant with the mechanism of a kind of pair of back rest.
Background technology
In the existing air-jet loom, the back rest that has only an activity, because the cornerite of warp thread on tension axis changes with the variation of beam of a loom diameter, tension force changes with the variation of yarn beam diameter simultaneously, the defective of warp on loom tension force unusual fluctuations shows as the vibration of loom, makes loom can not produce high efficient, and rotating speed can not promote, loom can be turned round at a high speed and efficiently, stable warp tension must be arranged as prerequisite.
Summary of the invention
Purpose of the present invention is exactly will solve existing air-jet loom to lead the various defectives of warp thread with single back rest, provides a kind of warp tension to remain stable two back rest mechanism.For this reason, the present invention is by the following technical solutions:
The mechanism of a kind of pair of back rest is characterized in that: but described mechanism comprise collar, built-in beam, about shift bracket, walking beam and walking beam grip frame.But the two ends walking beam grip frame be connected by axle about on the shift bracket, and be screwed, walking beam directly is contained in two walking beams and grips in the inner chamber of both ends open of frame, and in the opening part bolted, built-in beam two ends dress bearing, behind the collar close-fitting, but about directly being placed in the two halves round belting on the shift bracket.
As the further of such scheme improved and replenish, the present invention also comprises following additional technical feature:
But described walking beam grip frame with about the relative position of shift bracket can adjust, also be that the cornerite of walking beam and built-in beam can be regulated.
Described walking beam and built-in beam are all the structure of hollow pipe.
Described collar is made of plastics, and is suitable for the frequent loading, unloading of built-in beam.
But shift bracket has the device greater than semicircle of anti slip about described.
When the present invention uses, but shift bracket is fixed by bolts on the corresponding scale position at loom frame two ends according to the needs of fabric about two ends, but two walking beams grip frame be connected to by axle about on the shift bracket, and be screwed, walking beam grips the frame other end and is installed in the corresponding part in the loom, walking beam directly is contained in two walking beams to grip in the inner chamber of both ends open of frame, requirement according to warp thread, regulate position with built-in beam, and in the opening part bolted, built-in beam two ends dresses bearing, and with the collar close-fitting after, but about directly being placed in the two halves round belting on the shift bracket.
Use the present invention can reach following beneficial effect: increasing by one on the carriage of the left and right sides can be with the built-in beam of warp thread rotation, because the cornerite of warp thread on tension axis do not change with the variation of beam of a loom diameter, and the pressure angle of walking beam and built-in beam remains constant, so can more accurately measure warp tension and keep stable, for the efficient that improves loom, guarantee that it runs up, provide good mechanism to guarantee.When axle need be changed, need not any instrument and just fixedly sill bolt collar, bearing can be taken off together, just can change through axle, rational in infrastructure, easy to use, simple.

Fig. 2 is the front view that walking beam grips frame 5 among the present invention.
Fig. 3 is the cutaway view of two beams among the present invention.
Among the figure: 1, collar; 2, built-in beam; But shift bracket 3; 4, walking beam; 5, walking beam grips frame.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is described in detail.
As shown in Figure 1-Figure 3, but the present invention includes collar 1, built-in beam 2, about shift bracket 3, walking beam 4 and walking beam grip frame 5.But two walking beams grip frame 5 be connected by axle about on the shift bracket 3, and be screwed, walking beam 4 directly is contained in two walking beams and grips in the inner chamber of both ends open of frame 5, and in the opening part bolted, built-in beam 2 two ends dress bearing, and with collar 1 close-fitting after, but about directly being placed in the two halves round belting on the shift bracket 3; Described walking beam 4 and built-in beam 2 are all the structure of hollow pipe, and described collar 1 is made of plastics, and is suitable for frequent loading, unloading, but shift bracket 3 has the device greater than semicircle of anti slip about described.
When the present invention uses, but shift bracket 3 is mounted and fixed on the corresponding scale position at loom frame two ends according to the needs of fabric about two ends, but two walking beams grip frame 5 be connected to by axle about on the shift bracket 3, and be screwed, walking beam grips frame 5 other ends and is installed in the corresponding part in the loom, demand according to warp thread, walking beam 4 directly is contained in walking beam to grip in the inner chamber of both ends open of frame 5, regulate position with built-in beam 2, and in the opening part bolted, built-in beam 2 two ends dress bearing, and with collar 1 close-fitting after, but about directly being placed in the two halves round belting of shift bracket 3, when when axle need be changed, need not any instrument just can be with fixing sill bolt collar 1, bearing takes off together, just can change, finish changing behind axle, directly with built-in beam 2 band collars 1 through axle, but bearing is packed into two ends about get final product on 3 on the shift bracket.
