Is the main device in belt conveyor frame fixed plate on the surface of the horizontal machining two rectangular slot. Swap device in belt conveyor roller and support. To make a vertical state, the straight slot is designed along the width direction of the fixed plate with an arc groove structure, bolt holes to start device on the fixing plate on the right side, and the arc direction extension, until the edge through in place,
The comprehensive exchange efficiency through this way can improve the product design of belt conveyor idlers and support, fully meet the needs of users in the field of efficient operation of the prominent point is mainly made of rubber cushion rubber ring more rapid extrusion to the two ends of the drum device with clamping ring, main axle is provided with strong support frame. Through the connecting rod buffering rubber ring, clamping bracket and support each other in series after hardening treatment, use this way to make the drive belt roller, can guarantee the special clamp is matched with the heat resistant conveyor belt used to type friction roller is more satisfactory.
