Common expression method of layered conveyor belt: take nn200 1000 * 6 * (6 + 3) as an example, nn200 represents nylon 200 type, 1000 represents the width of conveyor belt, 6 represents the number of layers of nylon cloth, and (6 + 3) represents that the upper and lower covering glue of conveyor belt is 6 mm and 3 mm thick respectively.

鋼絲繩芯輸送帶常用表示方法：以ST1000H1000?4.0-6.0-6.0為例：ST1000表示的是強(qiáng)度規(guī)格，為1000N/mmH表示的是覆蓋膠的性能級(jí)別：1000表示的是產(chǎn)品的寬度,單位mm，4.0表示的是鋼絲繩的直徑，單位mm，6.0-6.0表示的是上下覆蓋膠的厚度，單位mm。 整芯輸送帶的表示方法：一般煤礦用PVC和PVG整芯阻燃輸送帶用強(qiáng)度級(jí)別和輸送帶寬度來(lái)表示。

Commonly used representation method of steel cord conveyor belt: st1000h1000? 4.0-6.0-6.0 as an example: st1000 refers to the strength specification; 1000N / MMH refers to the performance level of the covering glue; 1000 refers to the width of the product, in mm; 4.0 refers to the diameter of the wire rope, in mm; 6.0-6.0 refers to 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 used in general coal mine is expressed by strength grade and conveyor belt width.

強(qiáng)度級(jí)別一般分為：4級(jí)、5級(jí)、6級(jí)、7級(jí)、8級(jí)、9級(jí)、10級(jí)、11級(jí)和到16級(jí)輸送帶，分別對(duì)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(jí)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(duì)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(lái)解決，添加到運(yùn)輸帶不打滑為止。但不應(yīng)添加過(guò)多，以免使皮帶承受不必要的過(guò)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(lái)增大張緊力。

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.

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(zhǎng)，當(dāng)行程不夠時(shí)也可重新硫化或加大張緊行程來(lái)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(huì)引起運(yùn)輸帶下側(cè)跑偏。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(lái)調(diào)整。一般的講，下側(cè)跑偏是可以糾正的，可以通過(guò)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(lái)達(dá)到糾偏的目的。

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. In general, the lack of parallelism of the lower idler and levelness of the roller will lead to the lower side deviation of the conveyor belt. This situation is basically caused by poor cleaning device, material sticking on the lower idler, non parallel roller of counterweight, deflection of counterweight support and non parallel lower idler. The specific situation should 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, the lower V-shaped idler, or installing the lower centering idler.
