Common representation method of steel cord conveyor belt: take st1000h1000? 4.0-6.0-6.0 as an example: st1000 represents the strength specification, 1000N / MMH represents the performance level of covering glue: 1000 represents the width of the product, unit: mm, 4.0 represents the diameter of steel cord, unit: mm, 6.0-6.0 represents the thickness of upper and lower covering glue, unit: mm. Expression method of whole core conveyor belt: PVC and PVG whole core flame retardant conveyor belt used in general coal mine is expressed by strength grade and conveyor belt width.

強(qiáng)度級別一般分為：4級、5級、6級、7級、8級、9級、10級、11級和到16級輸送帶，分別對應(yīng)的強(qiáng)度為680S、800S、1000S、1250S、1400S、1600S、1800S、2000S、2240S、2500S、2800S、3100S和3400S。

The strength grades are generally divided into four grades: Grade 4, grade 5, grade 6, Grade 7, Grade 8, grade 9, grade 10, grade 11 and up to grade 16. The corresponding strength is 680s, 800s, 1000s, 1250s, 1400s, 1600s, 1800s, 2000s, 2240s, 2500s, 2800s, 3100s and 3400s respectively.

橡膠輸送帶寬度一般為：500mm、650mm、800mm、1000mm、1200mm、1400mm、1600mm、1800mm等。所有的運(yùn)輸帶必須接成環(huán)形才能實(shí)際使用，所以輸送帶的接頭是非常關(guān)鍵的。接頭的好壞直接影響著橡膠運(yùn)輸帶的使用壽命和輸送線能否平穩(wěn)順暢地運(yùn)行。

The width of rubber conveyor belt is generally 500mm, 650mm, 800mm, 1000mm, 1200mm, 1400mm, 1600mm, 1800mm, etc. All conveyor belts must be connected into a ring in order to be used in practice, so the joint of conveyor belt is very critical. The quality of the joint directly affects the service life of the rubber conveyor belt and the smooth operation of the conveyor line.

分層橡膠運(yùn)輸帶的接頭：可以根據(jù)需要采用機(jī)械接頭、冷粘接頭、熱硫化接頭等接頭方法。一般冷粘接頭、熱硫化接頭采取的是階梯式結(jié)構(gòu)接頭。 PVC和PVG整芯阻燃運(yùn)輸帶的接頭：由于整芯帶的結(jié)構(gòu)比較特殊，接頭不太容易，所以大多數(shù)采用機(jī)械接頭辦法，即皮帶扣接頭。但是8級以上的輸送帶，為了保證接頭效果，一般還是采用熱硫化接頭的方法。接頭的結(jié)構(gòu)都是指狀接頭。PVC和PVG整芯阻燃運(yùn)輸帶的熱硫化接頭工藝比較復(fù)雜，對設(shè)備的要求也比較高。

Joint of layered rubber transport belt: mechanical joint, cold bonding joint, hot vulcanization joint and other joint methods can be used as required. Generally, the cold bonded joint and hot vulcanized joint are of stepped structure. Joint of PVC and PVG whole core flame retardant conveyor belt: due to the special structure of the whole core belt, the joint is not easy, so most of them adopt mechanical joint method, namely belt buckle joint. But for the conveyor belt above grade 8, in order to ensure the joint effect, the hot vulcanization joint is generally used. The structure of joint is finger joint. The heat vulcanization joint process of PVC and PVG whole core flame retardant conveyor belt is more complex, and the requirements of equipment are also higher.

使用重錘張緊裝置的皮帶運(yùn)輸機(jī)在運(yùn)輸帶打滑時(shí)可添加配重來解決，添加到運(yùn)輸帶不打滑為止。但不應(yīng)添加過多，以免使皮帶承受不必要的過大張力而降低運(yùn)輸帶產(chǎn)品使用壽命，使用螺旋張緊或液壓張緊的皮帶運(yùn)輸機(jī)出現(xiàn)打滑時(shí)可調(diào)整張緊行程來增大張緊力。但是，有時(shí)張緊行程已不夠，橡膠輸送帶產(chǎn)品出現(xiàn)了性變形，這時(shí)可將運(yùn)輸帶截去一段重新進(jìn)行硫化，在使用尼龍輸送帶或EP輸送帶時(shí)要求張緊行程較長，當(dāng)行程不夠時(shí)也可重新硫化或加大張緊行程來解決，運(yùn)輸帶上下兩側(cè)是相互影響又相互獨(dú)立的。

When the belt conveyor uses the heavy hammer tensioning device, the counterweight can be added to solve the problem until the belt does not slip. However, it should not be added too much, so as not to make the belt bear unnecessary excessive tension and reduce the service life of the belt products. When the belt conveyor with spiral tension or hydraulic tension skids, the tension stroke can be adjusted to increase the tension. However, sometimes the tension stroke is not enough, and the rubber conveyor belt product has permanent deformation. At this time, a section of the conveyor belt can be cut off and vulcanized again. When nylon conveyor belt or EP conveyor belt is used, the tension stroke is required to be longer. When the stroke is not enough, the tension stroke can be vulcanized again or increased. The upper and lower sides of the conveyor belt are mutually affected and independent.
