Description

Technical Field

[0001] The invention relates to the technical field of loom equipment, and in particular to a light-load back beam system. Background Art

[0002] The back beam system of the current loom has a large moving mass and moment of inertia. When weaving light and thin fabrics, in order to reduce the breakage of the warp yarn, it is necessary to reduce the speed of the loom to increase the compensation effect of the back beam on the warp yarn tension fluctuations, thereby reducing the dynamic tension amplitude of the warp yarn, which makes the loom unable to operate efficiently.

[0005] A light-load rear beam system comprises a rear beam bracket, a base, a support beam, a roller bracket, a fixed support, a connecting seat, a swing shaft, a support seat, a swing rod, a fixed rod, and a rear guard rod. The base is installed on the rear beam bracket, a support beam is installed between two bases, fixed supports are installed on the sides of the support beam near both ends, a swing shaft is installed between the two fixed supports, a plurality of connecting seats are installed on the side of the support beam, the connecting seat and the fixed support are arranged in a straight line, the swing shaft passes through the connecting seat, a fixed rod is installed on the side of the connecting seat away from the support beam, a plurality of support seats are installed on the swing shaft, a swing rod is installed on the upper part of the support seat, a groove is opened on the fixed support, the rear guard rod is installed in the groove on the fixed support, the roller bracket is installed on both ends of the swing shaft passing through the fixed support, and a roller compression spring is connected between the roller bracket and the base.

[0006] Preferably, the fixed support and the swing shaft are connected via a bearing.

[0007] Preferably, a tension rod bracket is installed at the bottom of the connecting seat, and the tension rod is installed on the tension rod bracket.

[0008] Preferably, a baffle is installed on the inner side of the fixed support.

[0009] Compared with the prior art, the invention has the following beneficial effects: the warp let-off is stable and uniform, the yarn tension is kept constant, and the efficient operation of the loom is ensured. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 2 It is a schematic diagram of the working surface of the present invention. DETAILED DESCRIPTION

[0012] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0013] like Figure 1-2 As shown, a light-load rear beam system includes a rear beam bracket 1, a base 2, a support beam 3, a roller bracket 4, a fixed support 5, a connecting seat 6, a swing shaft 7, a support seat 8, a swing rod 9, a fixed rod 10, and a rear guard rod 11. The base 2 is installed on the rear beam bracket 1. The rear beam bracket 1 is provided with a plurality of adjustment holes. By adjusting the connecting hole positions, the relative position can be changed. A support beam 3 is installed between the two bases 2. The two ends of the support beam 3 are connected to the base 2 by screws through a plurality of hole positions. Two fixed supports 5 and a plurality of connecting seats 6 are installed on the side of the support beam 3. The fixed supports 5 and the connecting seats 6 are arranged along the length direction of the support beam 3. The fixed seats 5 are located on the side of the support beam 3 near the two ends. The swing shaft 7 is inserted into the holes on the fixed support 5 and the connecting seat 6. The fixed support 5 and the swing shaft 7 are connected by a bearing to limit the axial movement of the swing shaft 7. The side of the connecting seat 6 away from the support beam 3 is installed with a fixed rod 10 by screws. The upper part of the support seat 8 is installed with a swing rod 9. The support seat 8 is installed on the swing shaft 7 by screws. After the support seat 8 is loosened, it can rotate radially on the swing shaft 7 to adjust the angle between the swing rod 9 and the fixed rod 10, that is, the surrounding angle of the warp yarn to the swing rod 9. A groove is provided on the fixed support 5, and the rear guard rod 11 is installed in the groove on the fixed support 5. The roller bracket 4 is installed on both ends of the swing shaft 7 passing through the fixed support 5. A roller compression spring 15 is connected between the roller bracket 4 and the base 2. The roller compression spring 15 absorbs the high-frequency fluctuation energy generated by the swing shaft 7 under the action of dynamic tension to ensure accurate detection of the tension sensor.

[0014] A tension rod bracket 13 is installed at the bottom of the connecting seat 6, and a tension rod 14 is installed on the tension rod bracket 13. The installation of the tension rod 14 avoids the change of the surrounding angle of the warp yarn to the fixed rod 10 caused by the change of the diameter of the weaving beam.

[0015] A baffle 12 is installed on the inner side of the fixed support 12 to limit the axial movement of the tension rod 14 on the tension rod bracket 13.

[0016] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for those skilled in the art, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
