OVERVIEW

BELT QUICK CONNECTOR is a latest innovation that creates a new method of conveyor belt joint (Invention Patent No: ZL200610053597.1). The most significant advantages are: fast assemble, high strength, low cost and long service life. BELT QUICK CONNECTOR is departed into two slices. The upper slice is thicker than the lower slice. There is a 20mm oblique section at both ends of the quick connector (see Figure 1).

INSTALLATION

STEP 1. Make a fitting body

Peel off the top and bottom rubber layer of the conveyor belt joint body about 11-16mm (According to different product specification). (See Figure 2)

Figure 2

STEP 2. Apply the adhesive

2.1 Clamp the two ends of upper slice or tie them with ropes or wires (see Figure 3).

2.2 Clean the dust on the surface of the quick connector inner part.

2.3 Apply the adhesive (conveyor belt cold bonding adhesive) with a brush to the inner surface of quick connector repeatedly, as well as both sides of the belt fitting body

Figure 3

STEP 3. Assemble and bond

It should be done when the adhesive is nearly dry (when the adhesive is not sticky).

3.1 Cover a nylon film or fabric on each side of the belt fitting body surface to avoid the fitting body easily sticking to the connector.

3.2 Put the two belt fitting bodies in position and make sure the edge of conveyor belt and the edge of quick connector lie on a straight line (see Figure 4).

3.3 Pull out the bottom nylon film first to fix the conveyor belt joint body. Then, pull out the top nylon film. Untie the upper slice of the quick connector and press the surface to ensure a good firm bond.

STEP 4. Reinforce by bolts

4.1 Drill holes on the conveyor belt with a hand electric drill according to the holes location on the quick connector.

4.2 Put the specially-made bolts and nuts through the holes of the connector. Fix and tighten the bolts with a hexagonal wrench (see figure 5).

STEP 5. Seal the edge

Nail barbed sealing nails on the joint edge of up direction to prevent the edge cocked. Sealing nails are often used at 2-3 cm intervals (see Figure 6).

TIPS：

1. EASY JOINT METHOD：SCREW DOWN THE BOLTS FIRST, THEN APPLY THE ADHESIVE. First insert both ends of the belt fitting bodies into BELT QUICK CONNECTOR sleeves, screw down the bolts after drilling holes. Then apply the adhesive to the inner surface of joint part outside the screws. Finally nail the sealing nails. This method can speed up the belt joint, particularly in a humid environment where adhesive cannot be cured in time.

2. THE WIDTH OF BELT QUICK CONNCTOR SHOULD BE A LITTLE NARROWER THAN THE BELT. If the BELT QUICK CONNECTOR is wider than the belt, it would be easily damaged in case of belt deviation, thus seriously reduce its service life. BELT QUICK CONNECTOR could be cut. It is normally 10mm narrower than the belt.

3. THE BOLTS MAY MEED TO BE HANDLED. The bolts should fit the belt thickness. If the bolts are too long, they should be grinded off by the grinder.

4. HOW TO MASTER THE ADHESIVE. Apply the adhesive twice for better performance. The second applying should be done when the first applied glue is nearly dry. The optimum time to glue: the adhesive is not sticky when put your finger on it. If the adhesive is hard to dry at a low temperature, blowing it with a drier.

5. HOW TO TIGHTEN THE BOLTS. The bolts should be tightened gradually and repeated three times. Because the rubber is elastomer. The general tightening torque is 150N. If the belt will run immediately as soon as the belt joint finished when

the adhesive has not yet dry, the tightening torque should be increased to 200N.

6. THE BOTTOM RUBBER LAYER OF THE CONVEYOR BELT JOINT BODY MAY NOT BE PEELED OFF. If the bottom rubber layer is very thin, it may not be peeled off. But it must be roughened by the hand-held grinder before applying the adhesive.
