Conveyor Belt Joint Technology
In order to standardize and improve the quality of the belt interface overhaul, especially for this Technical Specification.
1, the use of
1.1 equipment repair time.
1.2 by the use of equipment management department approval before using this method.
2, belt buckle overhaul Technical specifications
2.1 Belt buckle use specifications: B500 belt use 55 # belt buckle, B650 and B800 belt use 65 # belt buckle, B1000 belt use 75 # belt buckle.
2.2 cross-belt section perpendicular to the longitudinal centerline and belts, angle measurement verticality error is not larger than 2mm / m.
2.3 Belt sides of the interface to use pliers clamp and tighten the belt fixed, ensure that the interface section from Rally (interface length the need to ensure easy construction).
2.4 Belt buckle placed should be uniform, two pairs of belt buckles bite to positive, about deviation is less than 1mm; reserve pin gap should be uniform, 55 # and 65 # pin buckle reserve space no more than 8mm, 75 # belt buckle aside pin gap is not more than 10mm.
2.5 Belt buckle gluten is the working surface (ie, the strip layer).
2.6 Belt buckle placed on both sides of allowance should be uniform, usually 20-30mm. After installing the belt buckle aside part cut off by 60 ° angle.
2.7 When beating belt buckle, stud belt to pass through, while the exposed portion of the nail head to bend.
After 2.8 belt buckle finished, use pins to connect. When connecting to the pin length is longer than the belt buckle 40 ~ 60mm, one end sharpened, pointed end first gently tap to enter. After typing pin, need to be pointed end unnecessary portion is removed to ensure the pin is shorter than the belt buckle 4 ~ 8mm, the pin is placed between the belt buckle, belt buckle ends knocked flat to prevent the pin ran.
2.9 pin requirements: 55 # and 65 # 8 # wire belt buckles, belt buckles 75 # Ф6 round use. The need to ensure the unity of the pin shall not be welded or otherwise.
2.10 In order to reduce the leakage of material, belt buckle plastic glass available at filling the gap, before use to ensure that glass glue harden.
2.11 Demolition connected interfaces on both sides of the belt after belt pliers, conduct a trial run and adjust the belt, make sure that the belt is not deviation.
3, cold glue interface (adhesive interface) Maintenance Technical Specifications
3.1 Belt lap belt length is generally 1 to 1.2 times the width, each separated by 200mm ~ 300mm make a step. The first step stripping layer canvas layer, and so on.
3.1.1B500 lap belt length of 500-600mm, each separated by 200mm to make a step. The number of steps is 2-3.
3.1.2B650 lap belt length of 600-750mm, 200-250mm make each separated by a step. The number of steps is three.
3.1.3B800 lap belt length of 750-900mm, 250-300mm make each separated by a step. The number of steps is three.
3.1.4B1000 lap belt length 1050-1200mm, each separated by a step 350-400mm do. The number of steps is three.
3.1.5 lap belt scale length is 600mm, each separated by 200mm to make a step. The number of steps is 2-3.
3.1.6 The two sides before crossing plastic edge removal, both sides of the plastic side after crossing the reservation.
3.2 Interface Type
3.2.1 bevel, bevel angle of 60 °.
3.2.2 straight mouth. At present, I plant the basic use of this form.
3.3 straight butt, cross-belt section perpendicular to the longitudinal centerline and belt, angle measurement verticality error is not larger than 2mm / m. At the same time on both sides of the interface to use the belt clamping pliers and tighten the belt fixed, ensure that the interface section from Rally (interface length the need to ensure easy construction).
3.4 When stripping the interface, the material side stripping thin plastic surface (ie non-face), the other side of the thick rubber surface stripping (ie Face).
3.5 stripping steps to control the depth of cut of each step can not cut the lower line.
3.6 Use steel grinding wheel grinding belt. Grinding process should be uniform, must not be left dead, nor fight focal line layer can not be broken. After grinding, the interface surface debris with a broom sweeping clean, then wipe gasoline.
3.7 Belt interfaces before gluing to preheat temperature reaches about 50 ℃ before proceeding gluing. Glue before use to mix well. Gluing should be uniform, the first layer of glue around 0.5mm, a second layer of plastic about 0.3mm, total thickness not exceeding twice gum 1mm. To be glue dry and then brush the second layer.
3.8 gluing Heat uniformly, temperature controlled at around 40 ~ 60 ℃, hekou to glue tack appropriate.
3.9 hekou forward interface to pad below the real, on both sides of the positive and align the ends of the belt longitudinal centerline of the overlap deviation is less than 1mm / m.
3.10 hekou pressurized tamping, from the middle to the all around with a wooden hammer three times or more, prevent product gas within the interface. Belt on both sides of pliers with a belt clamping force from the belt to ensure that the docking section.
3.11 glued complete with spikes can be reinforced according to usage. Spike mainly for strengthening the position of head and tail of each step, each part of the two rows of studs reinforcement spacing between the spikes of 30-40mm.
3.12 gluing belt, roasted glue, when hekou to ensure a good working environment, good dust-proof measure.
Void filled with glue 3.13 interface.
3.14 Interface maintenance period of not less than three hours.
After removal of the interface on both sides of the belt belt 3.15 maintenance pliers, conduct test and adjust the belt, make sure that the belt is not deviation.
