Vulcanization joint method of belt vulcanizing machine

4. Pay attention to the usual maintenance of the belt vulcanizing machine. Before the belt vulcanizing machine, check and test the temperature of the heating plate, the leakage of the water pressure plate, the integrity of the electric control box and the cable. If multiple vulcanizing machines are used in combination, a piece of 0.3mm thick shall be laid on the joint seam

Copper skin around.

5. Before vulcanizing the tape, be sure to select a spacious, well-ventilated, low-temperature, low-moisture and dust place on the installation line of the tape conveyor; during the vulcanization process, the joints should not be exposed to rain. There is a place with a roof or a shed with tarpaulin.

6. The straightness of the tape joint is directly related to the use of the tape after the joint. It is the basic condition for ensuring the normal use of the tape. The center line of the tape must be carefully determined.

7. In order to reduce the stress of the joint part when passing through the roller during operation, and facilitate the laying, alignment and alignment of the tape joint part on the vulcanizing machine, the tape joint angle is consistent with the angle of the heating plate of the vulcanizing machine.

8. When stripping the head of canvas and nylon core tape and cutting the cloth layer, pay attention to prevent cutting the next cloth layer. When "peeling" the steel cord core tape, use nutcracker to clamp the rope end of the steel cord, apply horizontal force to the outside in the horizontal direction, and do not allow the steel cord to be bent. In addition, the wire rope at the joint should be stripped of the surface with glue to ensure the joint

9. When polishing the joints, the joints should be sufficiently roughened to ensure that the polished surface should fully contact the adhesive surface, but be careful not to damage the cloth layer.

10. When applying glue, don't do too much, do not miss the application. Each time you apply the glue, it must be dried. The degree of drying can be lightly adhered to the surface of the glue with your fingers.

11. When laying steel wire rope with steel wire core tape, the steel wire rope should be kept parallel to the center line of the tape and must not be bent. At the same time, the distance between each group of steel wire ropes and the original should be consistent; there should be core rubber spacing between the steel wire ropes and the filling amount should be sufficient.

12. Before bonding the adhesive tape, wipe the surface with solvent; when molding, you should repeatedly confirm whether the center line is consistent; when laying the steel rope, pay attention to the linearity of the steel rope.
 
13. After the two belt joints are combined, the adhesive should be laminated. You can use a wooden hammer to hit the surface in sequence, or use a needle to pierce the hole to eliminate the gas in the adhesive layer.

14. During the vulcanization process, pay close attention to the pressure of the water bladder, and make up for pressure in case of leakage. At the same time, pay attention to the vulcanization temperature display to prevent problems caused by insufficient or excessive vulcanization temperature caused by electrical appliance failure.

15. After the vulcanization and heat preservation time of the belt vulcanizing machine is reached, the vulcanizing machine can only be disassembled when the vulcanization temperature is reduced to 80 ° C.

16. Check the overall condition of the joint parts for bubbles, lack of glue and other abnormal conditions and check the deviation distance of the center line of the joint. At the same time, make the vulcanization record of the joint, and record the inspection in the "Joint Inspection Record Form".
