Description

An adjustable weaving shaft device of a velveteen rapier loom

technical field

The invention belongs to the technical field of textile equipment and relates to an adjustable weaving shaft device of a velveteen rapier loom.

Background technique

The rapier loom is the most widely used type of shuttleless loom. Among shuttleless looms, rapier looms are general-purpose looms for weaving small-batch, medium-batch, and frequently refurbished fabrics. It occupies a considerable weight in the total number of looms in the world. The range of fabrics processed by rapier looms is relatively wide, from medium-thick fabrics to light and thin fabrics, from clothing fabrics to industrial fabrics, from single-layer fabrics to terry and double-layer fleece fabrics, all belong to the scope of rapier loom weaving.

At present, many looms in our country are difficult to improve the running speed and processing quality due to many design defects. Therefore, it is necessary to transform the old looms to achieve the purpose of improving machine speed and productivity.

For example, the Chinese utility model patent application (application number: 201220434335.0) discloses a high-performance rapier loom, which includes a weaving shaft, a twisted rod, a heald frame, a steel box, a weft feeder, a rapier disc, a weft-connecting rapier, Guide rollers and cloth rolling rollers; wherein, the weaving shafts, twisted rods, heald frames and steel boxes are arranged in sequence; warp stoppers are arranged on the twisted rods; healds are arranged at equal intervals on the heald frames; The sword-passing disc and weft-connecting rapier heads are respectively arranged on the left and right sides of the steel box; a sword belt is wound on the sword-passing disc; the guide roller is arranged at the front end of the steel box; the cloth rolling roller is arranged on the guide bottom of the roll. The high-performance rapier loom of the utility model has many advantages such as simple structure, fast running speed and high processing quality.

However, when the weaving beam is conveyed, its tension fluctuates greatly with the change of its own weight, which is difficult to keep consistent, and it is easy to cause yarn breakage or loosening.

Contents of the invention

The purpose of the present invention is to solve the above-mentioned problems in the prior art, and propose an adjustable weaving beam device of a velveteen rapier loom, so that the warp on the weaving beam can maintain a constant tension.

The warp is wound on the weaving beam. With the delivery of the warp on the weaving beam, the weight of the weaving beam will gradually decrease, and the pressure sensor will transmit the weight change information of the weaving beam to the electric control box. The drive assembly is controlled by the electric control box, and the drive assembly drives the lower pressure rod vertically arranged on the cover plate to move down, and the lower pressure rod moves down to squeeze the anti-slip pad on the bearing seat, and the anti-slip pad receives force and transmits the force to the bearing The bearing seats on the vertical plates on both sides drive the weaving shaft to move down as a whole. The height of the shaft center is automatically adjusted through the weight change of the weaving beam, so that the tension of the warp on the weaving beam is kept constant. In addition, the pressure gauge at the lower end of the pressure sensor can display the pressure index for people to watch.

The lower pressing rod is a linear sliding rod, and the linear sliding rod is slidably connected with the cover plate. The driving assembly includes a cylinder fixedly connected to the upper end of the lower pressing rod, and the electric control box is electrically connected with the cylinder.

There is a positioning hole on the cover plate for the linear sliding rod to pass through, the linear sliding rod can slide up and down relative to the positioning hole, and the upper end of the linear sliding rod is fixedly connected with the end of the push rod of the cylinder. The electric control box controls the cylinder so that the linear slide bar slides vertically along the positioning hole, and its lower end squeezes the anti-skid pad on the bearing seat.

The lower pressing rod is a threaded rod, and the threaded rod is threadedly connected with the cover plate. The drive assembly includes a driven wheel connected to the upper end of the threaded rod and a motor fixed on the side riser. A driving wheel is fixed on the output shaft of the motor, and the driving wheel and the The driven wheel rotates through the belt, and the motor is electrically connected with the electric control box.

The output shaft of the motor is set upward, and the lower end of the motor is fixed on the cover plate. The rotation of the motor drives the driving wheel to rotate, and then drives the driven wheel to rotate together through the belt. The driven wheel drives the threaded rod to rotate and controls the threaded rod to move up and down. The threaded rod moves down and its lower end squeezes the anti-skid pad on the bearing seat.

The adjusting groove is rectangular, and both sides of the bearing seat abut against the adjusting groove.

Both sides of the side vertical plate are provided with transparent protective plates covering both sides of the adjustment groove.

By adopting the above structure, the adjusting tank can be sealed, and it is convenient for the staff to observe the internal structure of the adjusting tank. Avoid the components in the adjustment slot from detaching or popping out of the adjustment slot, causing them to affect normal work or hurting people after being ejected.

The protective plate is rectangular and made of tempered glass or transparent plastic.

Both tempered glass and transparent plastic have a see-through effect, and tempered glass and transparent plastic are not as fragile as ordinary glass, which is easy to scratch the skin after being broken, and has low safety.

The elastic member is a rubber block or a sponge block.

Both the rubber block and the sponge block have good elasticity, and both the rubber block and the sponge block are relatively easy to purchase in the market, and the cost is relatively low.

The pressure sensor is an ordinary pressure sensor.

The adjustable weaving shaft device of the velveteen rapier loom does not require high precision of the pressure sensor, so the use of a common pressure sensor can not only reduce the cost input, but also realize the transmission of basic pressure changes to the electric control box.

Compared with the prior art, the advantage of the adjustable weaving shaft device of the velveteen rapier loom is that the adjustable weaving shaft device of the velveteen rapier loom can adjust the axis height of the weaving shaft by itself by sensing the weight change of the weaving shaft , so that the tension of the warp on the weaving shaft is kept constant, and the warp is prevented from being broken or loosened due to the change of tension during the conveying process, which affects the normal operation of the velveteen rapier loom.
