In countries around the world mining industry and sea port wharf, agricultural processing should be able to see as a major railway station transport rubber conveyor belt, because of this rubber
Rubber conveyor belt connection becomes the primary issue.
Rubber conveyor belt is divided into layers, such as steel wire, PVC type, and rubber conveyor belt of seamless connection only adapt to the cold layers and length changes smaller stationary rubber lose
To send belt, not adapt to the mining working face telescopic connection of rubber conveyor belt, the rubber conveyor belt cold TIP TOR seamless connection technology is a Germany company long-term practice and summed up.

1.1 to determine the length of the connection
According to different purposes of multi-layer rubber conveyor rubber belt, choose the number of layers is different, if the lap length to choose long the waste material, and the overlapping part of will
In bearing strength is not enough to cause a tear of the conveyor belt or strip break accident. Rubber conveyor belt of the lap length is associated with the selected the strength of the conveyor belt,
Its computation formula is as follows:
(1) 1!Additional lap size (see table 1 for joint length).
(2) the width of the tape! Oblique cutting (about 16 "0.3).
For example: width 1000 mm belt strength rating (up or move, see table) + 630/4750 mm 300 mm (oblique) = 105 (0 the tape length) left oblique cut materials as shown in figure 2.
Figure 2 inclined cut diagram under the first layer basketwork 30 mm material at the end of tape when draw a 90 "of the CB baseline (see figure 2) according to the width of tape! = about 16" 0.3 cross diagonal line.
Table 1 rubber conveyor belt cold seamless connection reference this size only at one end of the tape measure and the line. Sometimes we need to cut down part of the multilayer conveyer belt in the middle, and then connect it up.
1.2 to replace a damaged belt
(1) the tape on the conveyor to release tension, and with the tension device to pull the adhesive tape tightly together. Mark chamfered edge on two central tension device, and cut off the tape.
(2) is replaced the tape parallel to the segment of chamfered edge cut down (the tape need to brace) on the shelf.
(3) the lap length calculation. Before and after connection or connection length (see chart). 2 + replaced tape section length + width of tape! Oblique section 0.3.
Storage conditions: in the storage and transportation should isolate the fire source, avoid sharp instrument, and has a larger corrosive chemicals contact, avoid long-term stored in sunlight.
Quality standard: 1. The ordinary conveyor belt (including high tenacity nylon conveyor belt) products perform GB7984-2001 standard.
2. The three resistant conveyor belt, heat resistant, acid and alkali resistant) perform GB10822-89 standard.
3. The flame retardant conveyor belt products perform MT147-95 standard.
