Description

A kind of raw silk cohesion detection device and its detection method that multifibres ingot detects simultaneously
Technical field
The present invention relates to a kind of raw silk detection device and method, especially a kind of raw silk cohesion detection and detection method.
Background technology
Raw silk cohesion refers to raw silk in the complexity to crack after friction.The obvolvent row of raw silk is raw silk quality One important indicator.
The raw silk of coherent difference, drawing force is also poor, cannot stand high speed loom friction, is easy in manufacturing process Hair, or even cut off;It is white at the position of obvolvent difference after woven into fabric, easily produce raw uneven dyeing, color not after dyeing The faults such as vivid.
Presently, there are with Y731 types currently in use shut out wave obvolvent machine, friction velocity be 80 ~ 125 times/min, meet The not rate request of fast-developing high speed shuttleless loom.The method examined at present is that the raw silk of single silk ingot is wound on device On, 20 in total, the knife rest that then rubs first grinds raw silk 45 observations once, and often 10 observations of mill are primary later, if half Raw silk cracking is more than 6mm, stops friction, records Rubbing number.A silk ingot is finished, continues next ingot, until finishing 20 A ingot takes obvolvent number of the average value round numbers of 20 silk ingots as this batch of silk, obvolvent number to be more than 120 times, then sentence Disconnected this batch of raw silk is 6A ranks.
Obvolvent service check is one of the subsidy inspection project of raw silk quality detection, in the world to raw silk not yet authority and Unified standard and technical specification.There are two main problems for existing obvolvent service check:1, raw silk cohesion is evaluated so far It still can go to evaluate using human eye sense organ, there are more human factor, different people may to the detection judging result of same a collection of silk Have very big difference, even if same person under different conditions to having Different Results the testing result of same a collection of silk.2, it lacks A weary method that can trace quality check process, the result of each detection are all recorded in raw silk notarial survey obvolvent and examine record Dan Shang, heavy workload, efficiency are low.
Therefore it is badly in need of being improved existing raw silk cohesion detection method and device.To improve silk industry quality Management level and competitiveness.
Invention content
It is an object of the invention to provide a kind of high degree of automation, accurate, testing result for raw silk cohesion detection Objective reliable raw silk cohesion row detection device.
Purpose to realize the present invention, the technical solution adopted is that:A kind of raw silk cohesion detection that multifibres ingot detects simultaneously Device, it is characterised in that:The raw silk cohesion detection device that multifibres ingot detects simultaneously includes linear reciprocation friction mechanism, clamping machine Structure, take-up mechanism, fixed thread mechanism, counting detection system, image capturing system, linear reciprocation friction mechanism include friction knife rest, Servomotor, support of motor, incomplete rack, partial gear, sliding rail, sliding block, sliding block are mounted on sliding rail, solid thereon Dingan County equipped with friction knife rest, servomotor be mounted on support of motor on connect with partial gear, incomplete rack with rub Knife rest is wiped to connect and be meshed with partial gear;Silk rolling hook is mounted in rack, from left to right successively by fixed thread mechanism, wrapping wire Mechanism and clamp system are mounted in rack;Clamp system includes upper clamp plate, lower clamp plate, steering engine, upper clamp plate and lower clamp plate and rudder Machine connects;Take-up mechanism includes upper brake pad, screw, roller, stepping motor, lower brake pad, upper brake pad and lower brake pad It is mounted on roller by screw, roller is connect with stepping motor;Fixed thread mechanism includes stepping motor, fixed thread bar, fixed thread Bar is connect with stepping motor;Data collecting card, microcontroller, computer and sensor for countering form counting detection system;Image Acquisition system includes camera, camera bracket, computer, and camera bracket is fixed on the rack, and is installed with takes the photograph thereon As head, camera is connect with computer.
The linear reciprocation friction mechanism connects partial gear by servomotor and drives incomplete rack linear It moves back and forth, realizes friction knife rest to raw silk reciprocating friction.
Brake pad and lower brake pad adjust the frictional force with roller by screw on the take-up mechanism, pass through stepping Motor carries out wrapping wire to 20 silk ingots simultaneously, and clamps upper brake pad by the upper clamp plate of clamp system and lower clamp plate and rub under Cleaning block keeps the tensile force of 20 raw silks invariable.
The fixed thread mechanism by raw silk across silk rolling hook be then passed through on fixed thread bar with one-to-one 20 holes of silk rolling hook, Drive fixed thread bar that raw silk is made to take up on fixed thread bar with stepping motor again.
The application method of the present invention is as follows:
Cracking situation of each section of raw silk by friction on 20 silk ingots is compared by observation, Rubbing number is recorded, judges raw silk Obvolvent performance, detailed process are:
Step 1)The raw silk of 20 silk ingots is passed through into 20 silk rolling hooks, then passes through fixed thread bar, then raw silk is fixed on 20 On brake pad;
Step 2)Rotate stepping roller, raw silk is wound on upper brake pad and lower brake pad, then rotate fixed thread bar by raw silk around It fastens on it, is rotated further by roller, protected by 20 upper brake pads and lower brake pad force of sliding friction equal with roller Demonstrate,prove the uniform tension in order of 20 raw silks.Finally by brake pad and lower brake pad on upper clamping plate and lower clamping board clamping;
Step 3)The speed that servomotor drives partial gear is controlled by microcontroller, to control friction knife rest(9)It is past Linear motion, and Rubbing number is recorded by sensor for countering;
Step 4)By camera acquire it is rubbed after raw silk image, be uploaded to computer carry out image procossing, if half Raw silk cracking is more than 6mm, stops friction, and record Rubbing number;
Step 5)It is repeated 20 times the content of step 2 ~ step 4, the inspection of 20 silk ingots is completed, takes the average value of 20 Rubbing numbers The obvolvent number of raw silk as the batch.Raw silk, image information and reviewer are stored to database, report is automatically generated Table.
In detection process, raw silk is tensed as a result of the force of sliding friction of upper and lower brake pad and roller so that every The tensile force that root raw silk is subject to is the same, then pass through clamp system clamp up and down brake pad so that raw silk when being rubbed above and below rub Cleaning block will not skid with rolling, and tension suffered by raw silk in friction process is kept not change.Simultaneously to silk on 20 silk ingots, and Silk was compared on silk ingot one by one in the past, had saved manual labor, improved the efficiency of detection.
The rotating speed for using microcontroller control servomotor, the information fed back by sensor for countering can make friction Knife rest rests on same position every time, facilitates each Image Acquisition.The raw silk image of acquisition carries out Computer Image Processing, sentences Medium well silk cracking situation, avoids the error for thinking that observation generates, improves the accuracy rate of detection.
