From above-mentioned, be necessary the back rest mechanism of water jet looms in prior art further to improve.
Summary of the invention
Task of the present invention is to solve the technological deficiency that the back rest mechanism of water jet looms in prior art etc. exists, and provides one to exempt from detachable back rest mechanism.
Its technical solution is:
One is exempted from detachable back rest mechanism, comprises left side back rest hold-down support, right side back rest hold-down support, the fixing back rest, oscillating back rest, left side back rest movable bearing support and right side back rest movable bearing support; Above-mentioned left side back rest hold-down support is fixed on loom left side warp let-off wallboard, one end of left side back rest movable bearing support is hinged on the back rest hold-down support of left side by axle, right side back rest hold-down support is fixed on loom right side warp let-off wallboard, one end of right side back rest movable bearing support is hinged on the back rest hold-down support of right side by axle, the two ends of the fixing back rest connect respectively the other end of left side back rest movable bearing support and the other end of right side back rest movable bearing support, on left side back rest movable bearing support and/or right side back rest movable bearing support, are provided with crowbar; The two ends of above-mentioned oscillating back rest are hinged in the corresponding end of the fixing back rest by left side back beam swinging arm and right side back beam swinging arm respectively.
Each end of above-mentioned oscillating back rest connects with corresponding back beam swinging arm by axle sleeve.
On the posterior segment, top of above-mentioned each back rest hold-down support, be provided with a semicircle positioning recess.
On above-mentioned each back rest hold-down support, be provided with an arc-shaped limit groove, the spacer pin on each back rest movable bearing support inserts in arc-shaped limit groove.
The two ends of the above-mentioned fixing back rest are respectively provided with an extension, are provided with tension force swing arm on extension.
The present invention has following useful technique effect:
The present invention is in the time that loom changes the outfit warp beam, can drive back rest movable bearing support upwards to swing by manually lifting crowbar, and carry on the fixing back rest and oscillating back rest and lift by back rest movable bearing support, warp beam changes the outfit after each back rest rises displacement, change the outfit etc. warp beam complete, reverse operating crowbar just can make each back rest synchronous reset, has easy to operate, safe, can not make the back rest come off and cause the features such as industrial accident.
Brief description of the drawings
Below in conjunction with accompanying drawing, the present invention is further described:
Fig. 1 is the structural principle schematic diagram of one embodiment of the present invention, only shows the partial structurtes of its corresponding loom side one side.
Fig. 2 is the plan structure principle schematic of Fig. 1 mode.
Detailed description of the invention
In conjunction with Fig. 1 and Fig. 2, one is exempted from detachable back rest mechanism, comprises left side back rest hold-down support, right side back rest hold-down support 1, the fixing back rest 2, oscillating back rest 3, left side back rest movable bearing support and right side back rest movable bearing support 4.Above-mentioned left side back rest hold-down support is fixed on loom left side warp let-off wallboard, and one end of left side back rest movable bearing support is hinged on the back rest hold-down support of left side by axle.Above-mentioned right side back rest hold-down support is fixed on loom right side warp let-off wallboard 5, and one end of right side back rest movable bearing support is hinged on the back rest hold-down support of right side by axle 6.The left end of the above-mentioned fixing back rest connects the other end of left side back rest movable bearing support, and the right-hand member of the fixing back rest connects the other end of right side back rest movable bearing support.On above-mentioned left side back rest movable bearing support and/or right side back rest movable bearing support, be provided with crowbar 7, in this example, crowbar is arranged on the back rest movable bearing support of right side.The left end of above-mentioned oscillating back rest is hinged on by left side back beam swinging arm on the left end of the fixing back rest, and the right-hand member of oscillating back rest is hinged on the right-hand member of the fixing back rest by right side back beam swinging arm 8.
