Abstract
The utility model discloses a rear beam structure for an air-jet loom. The rear beam structure comprises a fixed rear beam and a swing rear beam, wherein the fixed rear beam and the swing rear beam are supported by upper rear beam brackets arranged on the left side and the right side of the loom. The rear beam structure is characterized in that the upper rear beam brackets are fixedly connected with loom wallboards; lower supporting seat blocks are arranged below the upper rear beam brackets and also fixedly connected with the loom wallboards; supporting screw rods are arranged between the upper rear beam brackets and the corresponding lower supporting seat blocks; and the two ends of a beam roller are movably connected with swing arms through a shaft sleeve respectively. According to the rear beam structure, the upper rear beam brackets are connected with the loom wallboards directly or through the lower supporting seat blocks, so that the overall rigidity of the loom can be further enhanced and the stability of the loom is also greatly improved in the weaving process. Therefore, the rear beam structure is very suitable for a high-speed air-jet loom, especially a high-speed air-jet broad loom.
Description
Technical field
The utility model relates to a kind of air-jet loom, and is especially relevant with the back rest part of air-jet loom.
Background technology
Air-jet loom of the prior art, back rest part mostly adopts single-beam or twin-spar construction, compensates the variation of warp thread through the swing of a walking beam.Above-mentioned air-jet loom back rest structure comprises the fixedly back rest and an oscillating back rest, the above-mentioned fixedly back rest and oscillating back rest are supported by the T-shaped rear boom support that is arranged on the loom arranged on left and right sides, each T-shaped rear boom support lays respectively at the rear portion of the left and right wallboard of loom, adjacent wallboard.The beam roller of oscillating back rest is hinged on T-shaped rear boom support by the swing arm at two ends, is fixed the connection between the two ends of beam roller and swing arm, and namely beam roller self can not rotate.Be difficult to satisfy the requirement of weaving machine high-speed running due to the rigidity intensity of above-mentioned T-shaped rear boom support, therefore stability and bad when weaving machine high-speed turns round, especially true when being used for high-speed air-jet loom in wide size.Moreover because the beam roller can not rotate, the friction to warp thread in weaving process is large, easily causes broken yarn, has too much parking shift, fabric of poor quality.In addition, be positioned at the inboard of T-shaped rear boom support due to the swing arm at its two ends, assembling is complicated, also can bring difficulty to maintenance.
By as seen above-mentioned, be necessary the back rest of air-jet loom in prior art is partly further improved.
The utility model content
Task of the present utility model is to solve the technological deficiency that air-jet loom back rest of the prior art partly exists, and a kind of back beam structure for air-jet loom is provided.
Its technical solution is:
A kind of back beam structure for air-jet loom, comprise the fixedly back rest and oscillating back rest, fixedly the back rest and oscillating back rest by the top that is arranged on the loom arranged on left and right sides after boom support support, the swing arm of the beam roller of oscillating back rest by two ends is hinged on respectively behind each top on boom support; Be fixed together between the rear end face of the leading section of boom support and respective side loom side behind above-mentioned each top, above each after boom support below be provided with a supported underneath saddle, the leading section of each supported underneath saddle also and between the rear end face of respective side loom side is fixed together, and is provided with the studdle that can adjust bearing height between the supported underneath saddle that rear boom support is corresponding with it up; The two ends of above-mentioned beam roller are flexibly connected between the swing arm by axle sleeve and respective side respectively.
Above-mentioned beam roll cladding has hard chrome coating.
The two ends of above-mentioned beam roller are one section of boom support behind the top of outstanding institute respective side respectively, and each swing arm is positioned at the outside of boom support behind the top of respective side, the two ends of beam roller up after the outside of boom support be connected with the swing arm of institute respective side.
The utlity model has following useful technique effect:
1, the mode that behind top of the present utility model, boom support is taked directly and linked together by supported underneath saddle and loom side, can further strengthen the integral rigidity of loom, its stability also is largely increased in woven process, be highly suitable for high-speed air-jet looms, be particularly useful for high-speed air-jet loom in wide size.
2, oscillating back rest beam roller of the present utility model is owing to rotating, therefore when warp let-off process central sill roller changes corresponding swing with warp tension, can also corresponding rotation under the drive of warp thread, can greatly less roll body to the friction of warp thread, broken yarn can not appear, be conducive to significantly reduce parking shift, improve the quality of fabric.
3, oscillating back rest beam roller of the present utility model two ends one section of boom support behind the top of outstanding institute respective side respectively, namely lengthen the beam roller, make assembling, and maintenance is more convenient.
