Oil path system used for double-needle-bar warp knitting machine

Abstract

The invention discloses an oil path system used for a double-needle-bar warp knitting machine. The oil path system comprises a heating pump oil device and an oil conveying pipe; the oil conveying opening of the heating pump oil device communicates with the oil conveying pipe; the oil absorption opening of the heating pump oil device communicates with oil holes in a bar body; the oil conveying pipeis mounted in the bar body; a plurality of threaded holes are formed in the pipe body of the oil conveying pipe; and an oil spraying system or an end cap is detachably connected with the threaded holes. According to the oil path system, the pressure of the oil path system can be adjusted freely, thereby improving the heat exchange performance of the oil path system and improving the lubricating performance on a connecting rod frame group in movement; for a wide double-needle-bar warp knitting machine, an uniform lubricating scheme for the connecting rod frame group is provided, and a scheme for uniformly heating the bar body and the weaving region is also provided; and the problem in lubrication of the connecting rod frame group in the movement process of an ultra-high-speed double-needle-bar warp knitting machine is solved, and performance guarantee for increasing the rotating speed of the double-needle-bar warp knitting machine to be 1200cpm or above is provided.

Description

technical field [0001] The invention relates to an oil circuit system for a double-needle bed warp knitting machine, which belongs to the technical field of warp knitting machines. Background technique [0002] The double-needle-bed warp knitting machine mainly drives the various mechanisms of the main engine to knit according to the designed stroke through the movement of the front and rear two-compartment connecting rod groups; the double-needle-bed warp knitting machines currently on the market are mainly concentrated in the width of 138 inches. The speed is mainly below 800cpm. The connecting rod frame group of the double needle bed warp knitting machine currently on the market is mainly soaked in the bed filled with lubricating oil, and the lubricating oil is splashed and lubricated to realize the lubrication of the front and rear two compartments of the connecting rod frame group. , and some are equipped with a heating cycle device to heat the lubricating oil in the fr...

[0002] The double-needle-bed warp knitting machine mainly drives the various mechanisms of the main engine to knit according to the designed stroke through the movement of the front and rear two-compartment connecting rod groups; the double-needle-bed warp knitting machines currently on the market are mainly concentrated in the width of 138 inches. The speed is mainly below 800cpm. The connecting rod frame group of the double needle bed warp knitting machine currently on the market is mainly soaked in the bed filled with lubricating oil, and the lubricating oil is splashed and lubricated to realize the lubrication of the front and rear two compartments of the connecting rod frame group. , and some are equipped with a heating cycle device to heat the lubricating oil in the front and rear compartments inside the bed, but in the face of wide-width double-needle bed warp knitting machines, such as 170 inches, 190 inches, 210 inches, etc., the splash of lubricating oil Lubrication and conventional heating circulation devices cannot ensure that the temperature of the front and rear cabins inside the wide-width double-needle bed warp knitting machine body is evenly heated. In the long-width knitting area, the uneven temperature will cause the knitting elements to be caused by temperature imbalance. Deformation, resulting in fabric weaving flaws; In addition, currently for high-speed double-needle bed warp knitting machines, such as ultra-high-speed double-needle bed warp knitting machines with a speed greater than 1200cpm and above, the existing lubrication methods and oil circuit systems cannot meet the continuous The lubrication requirements of the rod frame group will accelerate the wear of the connecting rod frame group under the high-speed motion state, which will affect the service life of the warp knitting machine
