The specific embodiment

The utility model now is described in conjunction with the accompanying drawings and embodiments.

The diameters of on-line measurement rubber roll is the basic skills of ensuring the quality of products, and the top roller diameter numerical value of only measuring is not enough, must the diameters that rubber roll is made be controlled in the margin of tolerance.Therefore, after automatically measuring the outside diameter of rubber roll, the diameter of measurement feeds back to feed control device, and feed control device is after comparison, and the amount of feeding of control feed control device reaches desired value up to the outside diameter of rubber roll.

The On-line Measuring Method of top roller diameter is a kind of discontiguous measuring method, carries out in the grinding process at 1 pair of rubber roll of emery wheel, just can dynamically reflect the outside diameter of rubber roll.As shown in Figure 1, rubber roll the 2, the 6th, about two in pairs configurations, the grinding of rubber roll also is two paired grindings together, therefore measure the cylindrical external diameter of rubber roll and must measure simultaneously by two rubber rolls 2,6.The top roller diameter measurement mechanism mainly is made up of optical sensor or capacitance sensor, signal amplifier and A/D converter.The top roller diameter measurement mechanism is made up of two-way.As shown in Figure 1, there are two sensors 5,4 to measure corresponding rubber roll 2,6 respectively.Rubber roll the 2, the 6th moves back and forth by direction of feed, and the position of sensor 5,4 is fixed, and in the rubber roll process, the distance of sensor and rubber roll external diameter changes.Sensor measurement goes out this change value, just can obtain as calculated rubber roll at linear diameter.A/D converter feeds back to feed control device with this at linear diameter.Feed control device mainly is made up of servo bag, servomotor, ball-screw, the action of the information of servo bag receiving converter control servomotor, and the driven by servomotor ball screw mobile table top that links controls the feeding and the retraction of mobile table top.

Rubber roll carries out grinding in use, returns mill according to the wearing and tearing and the yarn quality situation of rubber roll in specified period, presses outside diameter and returns mill number of times classification use, with the strict control of shelves rubber roll diameter difference, keep good concentricity.Shao Shi is a soft roll with the tubes having low hardness rubber roll for 72 °, and the regulation hardness of rubber roll is soft roll about Shao Shi is 65 °, uses soft roll to make and swims to distinguish and shorten 1.5-2mm, and curable grip is bigger than ebonite roller, and gripping irregularity can improve.

Emery wheel counterclockwise turns round, and rubber roll drives by transmission system and finishes rotation, and emery wheel is realized by emery wheel and rubber roll speed difference the grinding of rubber roll.Rubber roll is finished length feed by feed system in addition, and emery wheel carries out grinding to rubber roll when feeding.In process of production, emery wheel needs regular reconditioning owing to use some cycles.

Check the fineness degree behind the mill of rubber roll surface, desirable Surface Machining will reach the RA value of following setting: special carefully Surface Machining RA=0.4-0.6, medium Surface Machining RA=0.7-1.0.The rubber roll of this new technology processing, lap-ups clothing phenomenon will significantly reduce, and the rubber roll surface roughness can influence the glue roller winding flower clothing, and the rubber roll of special thin Surface Machining is the lap-ups clothing seldom.The curable grip of fiber is strengthened, and no sliding phenomenon is used novel rubber roll processor, and spun yarn joint time decreased shortens to originally 1/5th, does not have the generation of lap-ups phenomenon substantially.

Correct selection rubber roll cover difference and meticulous processing and fabricating are the rubber roll long service life, the key factor that operating condition and yarn quality are good.Rubber roll is the main special textile part in the spinning process, and its performance and manufacture craft play the heavy industry effect to the cotton yarn quality level, and the rubber roll technology is constantly progressive.
