Description

Double-roller tension adjusting mechanism of weaving machine

Technical Field

The utility model relates to a loom technical field especially relates to a two roller tension adjustment mechanism of loom.

Background

A weaving machine is a machine for forming fabrics, wherein a shuttle loom is a weaving machine in which a shuttle is used as a weft carrier to introduce a weft thread into a shed. The shuttle loom has a long history, exposes more defects in the using process, but has low operation and maintenance cost, still has advantages in many aspects and is widely used.

The pile warp tension roller is an important part of a shuttle loom, a spring is usually adopted to provide elasticity for the single pile warp tension roller, the pile warp tension roller is utilized to provide yarn tension, but the tension is difficult to adjust in the production process, the machine needs to be stopped, the production efficiency is influenced, and improvement is needed.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a two roller tension adjustment mechanism of loom realizes tensile regulation on line, promotes production efficiency.

To achieve the purpose, the utility model adopts the following technical proposal:

a twin roller tension adjustment mechanism for a weaving loom comprising: frame, first tension roller, second tension roller and gear drive, the frame both sides are provided with the carousel relatively, radially be provided with the spout on the carousel, be provided with the slider in the spout respectively, first tension roller sets up between two relative sliders, be provided with the spring that is connected with the slider in the spout, second tension roller sets up between two relative carousels and is located the below of first tension roller, be provided with one section arc rack on the excircle of carousel, gear drive sets up in the frame and is located arc rack one side, gear drive's output is provided with the gear with arc rack toothing.

Wherein the gear driving device is a motor.

The first bearings corresponding to the first tension rollers are respectively arranged in the sliding blocks, and the second bearings corresponding to the second tension rollers are arranged on the rotary table.

Wherein, be provided with the integral key shaft that runs through two carousels in the frame.

The frame is provided with a first guide roller positioned on one side of the first tension roller and a second guide roller positioned below the second tension roller.

And square grooves corresponding to the thickness of the rotary table are arranged on two sides of the sliding block.

The utility model has the advantages that: a double-roller tension adjusting mechanism of a weaving machine is characterized in that a first tension roller and a second tension roller are specially designed, a spring is used for elastically supporting a sliding block and the first tension roller, a certain tension is given to yarn passing through the first tension roller, a gear driving device is used for driving the gear and a rotary table to rotate, so that the second tension roller is gradually contacted with or separated from the yarn passing through the second tension roller, the tension of the yarn is changed, the on-line adjustment of the tension is realized, the machine does not need to be stopped, and the production efficiency is improved.

Fig. 1 is a schematic structural diagram of the present invention.

Detailed Description

The technical solution of the present invention is further explained by the specific embodiment with reference to fig. 1.

A twin-roller tension adjusting mechanism for a weaving machine as shown in fig. 1, comprising: frame 1, first tension roller 10, second tension roller 7 and gear drive 4, frame 1 both sides are provided with carousel 13 relatively, in this embodiment, be provided with the integral key shaft 8 that runs through two carousels 13 on the frame 1, ensure the synchronous rotation of two carousels 13.

The radial spout 11 that is provided with on the carousel, be provided with slider 12 in the spout 11 respectively, slider 12 both sides are provided with the square groove that corresponds with carousel 13 thickness, promote the stability that slider 12 removed along spout 11. The first tension roller 10 is arranged between two opposite sliding blocks 12 and moves along with the sliding blocks 12, and first bearings corresponding to the first tension roller 10 are respectively arranged in the sliding blocks 12, so that the rotation of the first tension roller 10 is facilitated.

In this embodiment, the chute 11 is provided with a spring 9 connected to the slider 12, and the spring 9 gives an elastic force to the slider 12 and the first tension roller 10, and gives a constant tension to the yarn 14 passing through the first tension roller 10, and elastically expands and contracts to accommodate irregular jumping of the yarn 14.

As shown in fig. 1, the second tension roller 7 is disposed between two opposite rotating discs 13 and below the first tension roller 10, and a second bearing corresponding to the second tension roller 7 is disposed on the rotating discs 13 to facilitate rotation of the second tension roller 7. In this embodiment, the frame 1 is provided with a first guide roller 2 located on one side of the first tension roller 10 and a second guide roller 6 located below the second tension roller 7, the yarn 14 runs through the first guide roller 2, the first tension roller 10, the second tension roller 7 and the second guide roller 6 in sequence, and the second tension roller 7 may not contact with the yarn 14 when the tension of the yarn 14 is sufficient.

Be provided with one section arc rack 5 on the excircle of carousel 13, gear drive 4 fixes in frame 1 and is located arc rack 5 one side, in this embodiment, gear drive 4 is the motor, can adopt servo motor, carries out rotation control through the PLC controller, and the precision is high. The output end of the gear driving device 4 is provided with a gear 3 meshed with the arc-shaped rack 5, when tension adjustment is needed, the gear driving device 4 drives the gear 3 to rotate, and then the rotary table 13 is driven to rotate for a certain angle, so that the second tension roller 7 is gradually contacted with or gradually separated from the yarns in the path, the tension of the yarns 14 is changed, and the tension on-line adjustment is realized.

The above description is only for the preferred embodiment of the present invention, and for those skilled in the art, there are variations on the detailed description and the application scope according to the idea of the present invention, and the content of the description should not be construed as a limitation to the present invention.
