Heat curing conveyor belt connecting method

1 fabric conveyor belt heat curing connection method:
A. Features: HTV HTV connection method is through the roller conveyor ends are connected together with a joint strength, long life characteristics, but
A joint long time.
B. Connection of heat curing operation
 a. joint length to determine the centerline positioning joints cutting, peeling, grinding, washing, drying and cold glue to connect the same law, covering the glue should be

cut
45 ° slope.
 b. glue evenly with a brush brushing with termination site, if the coarse mesh fabric with a core, you need to paint the third time.
 c. etc. glue dry, according to the direction of the tape core intermediate buffer area covered with gum paste and put gum paste and with a core net emission of air between the

gum paste and cored
Pressed, the tape ends bonded (laminated strip can be taken in the tape and adhesive tape on the interface syrup, adhesive sealing strip firmly and fully rolled
Real.
d. Check in a straight line on the center line
 e. curing temperature.
f. vulcanization time: curing time the temperature rose from curing temperature curing flatbed when the start time
Cotton canvas core ordinary band: 6 + (with a core layer + upper and lower rubber thickness / 1.5) × 1.5
Nylon, polyester vertical conveyor belt (except heat resistant conveyor belt): 12 + (with a core layer + upper and lower gum total thickness / 1.5) × 2 Units: minutes
 Heat resistant conveyor belt: 18 + (with a core layer + upper and lower gum total thickness / 1.5) × 2 Units: minutes
g. vulcanization after maintaining the pressure until the temperature dropped below 80 ℃, and then relief, open vulcanizing machine, remove the belt and check whether a

centerline
Straight line.
h. excessive width at the sides of the connector repairs. Lap joints length Table: Minimum lap length (unit: mm)

j. Precautions:
① vulcanizing machine width, length, and connectors should width, length match. Heating plate vulcanizing machine on each side of the longitudinal joints should exceed at least

50mm, each side should be higher than the transverse transport bandwidth of at least 50m
Heating plate vulcanization vulcanization segment should have been pressed on the more than 50 mm in length.
② vulcanizing machine according to the angle shall determine the direction of the joint angle in the direction of belt.
