Common expression of steel wire rope core conveyor belt: st1000h1000? 4.0-6.0-6.0 as an example: st1000 represents the strength specification, 1000N / MMH represents the performance level of the covering glue: 1000 represents the width of the product, in mm, 4.0 represents the diameter of the steel wire rope, in mm, and 6.0-6.0 represents the thickness of the upper and lower covering glue, in mm. Expression method of whole core conveyor belt: PVC and PVG whole core flame retardant conveyor belt for 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**高到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: Grade 4, grade 5, grade 6, Grade 7, Grade 8, grade 9, grade 10, grade 11 and * * high to grade 16 conveyor belts. 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 before they can be actually used, 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 whether the conveyor line can run smoothly.

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。

Joints of layered rubber conveyor belt: mechanical joints, cold adhesive joints, hot vulcanization joints and other joint methods can be adopted as required. Generally, cold bonded joints and hot vulcanized joints adopt stepped structure joints. 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. However, for conveyor belts above grade 8, in order to ensure the joint effect, the method of thermal vulcanization joint is generally adopted. The structures of joints are finger joints. The hot vulcanization joint process of PVC and PVG whole core flame retardant conveyor belt is relatively complex, and the requirements for equipment are also relatively high.

使用重錘張緊裝置的皮帶運(yùn)輸機(jī)在運(yùn)輸帶打滑時可添加配重來解決，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)打滑時可調(diào)整張緊行程來增大張緊力。

When the belt conveyor using the heavy hammer tensioning device slips, the counterweight can be added until the belt does not slip. However, too much should not be added to prevent the belt from bearing unnecessary excessive tension and reducing the service life of the conveyor belt. When the belt conveyor with spiral tension or hydraulic tension slips, the tensioning stroke can be adjusted to increase the tensioning force.

但是，有時張緊行程已不夠，橡膠輸送帶產(chǎn)品出現(xiàn)了性變形，這時可將運(yùn)輸帶截去一段重新進(jìn)行硫化，在使用尼龍輸送帶或EP輸送帶時要求張緊行程較長，當(dāng)行程不夠時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。一般情況，下托輥平行度、輥筒水平度不夠均會引起運(yùn)輸帶下側(cè)跑偏。

However, sometimes the tensioning stroke is not enough and the rubber conveyor belt products have permanent deformation. At this time, a section of the conveyor belt can be cut off and vulcanized again. When using nylon conveyor belt or EP conveyor belt, the tensioning stroke is required to be long. When the stroke is not enough, it can also be vulcanized again or increased. The upper and lower sides of the conveyor belt affect and are independent of each other. In general, insufficient parallelism of idlers and levelness of rollers will cause the lower side of the conveyor belt to deviate.

下側(cè)跑偏，而上側(cè)正常這種情況基本上是由于清掃裝置不良、下托輥粘有物料、配重的輥筒不平行、或配重支架偏斜、下托輥相互不平行所致，具體情況要根據(jù)實(shí)際情況來調(diào)整。一般的講，下側(cè)跑偏是可以糾正的，可以通過改善清掃裝置工作狀況、輥筒、托輥上粘有的物料、調(diào)整下側(cè)平托輥、下側(cè)V型托輥、或安裝下側(cè)調(diào)心托輥來達(dá)到糾偏的目的。

The lower side deviates, while the upper side is normal. This situation is basically caused by poor cleaning device, materials adhered to the lower idler, non parallel rollers of counterweight, deflection of counterweight support and non parallel lower idler. The specific situation shall be adjusted according to the actual situation. Generally speaking, the lower side deviation can be corrected by improving the working condition of the cleaning device, removing the materials stuck on the roller and idler, adjusting the lower flat idler, lower V-shaped idler, or installing the lower self-aligning idler.
