Cooling device for weft accumulator

Abstract

The invention discloses a cooling device for a weft accumulator. The cooling device comprises a cooling cover body and a cooling casing. The two ends of the cooling cover body are connected with the cooling cover body, a cooling disc is installed in the cooling cover body, the outer circumference of the cooling casing is provided with cooling convex pieces, the inner circumference of the cooling casing is provided with a routing mechanism, and a cooling groove is formed in the middle of the cooling cover body and matched with the cooling disc. The cooling disc comprises a central disc body and an outer wheel disc. A first cooling ring and a second cooling ring are arranged between the central disc body and the outer wheel disc, a first cooling strip is positioned between the central disc body and the first cooling ring, a second cooling strip is positioned between the first cooling ring and the second cooling ring, and a third cooling strip is arranged between the second cooling ring and the outer wheel disc. The device is simple in structure, scientific, convenient, convenient to manufacture, low in cost, high in targeted performance and good in cooling effect, and the service life of the weft accumulator is prolonged greatly.

Description

technical field [0001] The invention relates to a cooling device for a weft feeder. Background technique [0002] With the continuous development of the textile industry, our country is in the critical period of textile industry upgrading. A large number of emerging textile enterprises rely on technological progress and participate in the current fierce market competition. The focus of competition is the adjustment of product structure, the improvement of product grade and quality , and the fundamental shortcut to solve the problem of upgrading products is to accelerate the pace of technological progress in the weaving industry. [0003] The weft insertion rate of modern shuttleless looms is very high, usually above 1000m / min, the highest has exceeded 2000m / min, and the weft insertion process only takes 1 / 2 to 1 / 3 of the time of one revolution of the main shaft of the loom, so the weft yarn The take-out speed from the bobbin is very high, which is equivalent to 2 to 3 times...

AI Technical Summary

Problems solved by technology

The drum-type weft feeder uses the yarn storage drum with a large moment of inertia as the rotating part of the yarn winding, which is obviously very unfavorable for high-speed looms

[0005] With the continuous advancement of technology, the electronic weft feeder has entered the textile machinery industry and has become the main component of the current textile machinery. The existing electronic weft feeder is equipped with a circuit board inside to control the working state, but in order to improve the utilization rate, often The weft feeder is in an uninterrupted working state, and the circuit board will continuously generate heat. At present, the heat dissipation device of the circuit board generally adopts the traditional method of adding an aluminum plate on the circuit board as a radiator. Due to the weft storage Due to the limitation of the internal volume of the machine case, the aluminum plate radiator is generally small, so the heat dissipation effect is not good, and the circuit board in a high temperature state for a long time may burn out

Although the installation structure of adding an aluminum plate on the circuit board as a heat sink is simple, the heat dissipation effect is not obvious, and it is easy to damage the power board of the weft feeder, thereby affecting production efficiency
