Customized conveyor should pay attention to the parameters

Generally based on the requirements of material handling systems, material handling location of a variety of conditions, the production process and material characteristics to

determine the main parameters.

① Transmission capacity: conveyor Flexible Roller Conveyor transport capacity per unit time is the amount of material transported. In transport bulk materials, transportation of materials per hour mass

or volume calculations; during transportation into items, the number of pieces per hour transport calculations.

② Conveyor speed: increase transmission speed can increase transmission capacity. In order to make the traction belt conveyor length pieces and large, the conveying speed

increasing day by day. But high-speed powered roller conveyor operation of the belt should pay attention to vibration, noise, and start braking and other issues. For parts of the chain as a traction

Conveyors, conveyor speed should not be too large to prevent increased dynamic loads. Simultaneous process operation conveyors, conveyor speed production process requirements

should be determined.

③ component size: scantling including conveyor belt width, belt width, hopper volume, pipe diameter and vessel size. These have a direct impact scantlings conveyor conveying

capacity.

④ transport length and angle: transfer line length and inclination of the conveyor directly affect the size of the total resistance and the power required.

Conveyor drive means

known as the process zone. Fifteen period, the domestic production of light-duty conveyor belt a breakthrough, and gradually occupy in the Extendable conveyor belt industry

Important position, type specification has reached hundreds of different kinds, in many fields has been widely used.
A lightweight conveyor belt structure: light conveyor belt consists of cover, skeleton layer, the bottom, the skeleton is there mezzanine floor above the fabric. Cover is a

light conveyor belt conveying surface, according to the nature of the material transport, should have good heat resistance, oil resistance, water resistance

Resistance, aging resistance, corrosion resistance, antistatic, non-toxic, etc., materials are rubber, rubber blends, PVC, TPU, TPE, polyamide and fabrics. The core skeleton

layer fabric is generally one to three, the most commonly used for the floor. Warp the fabric material with a high modulus low stretch polyester filament as

More commonly used 1000D and 1500D two kinds. With polyester filament yarn, polyester monofilament nylon filament several, when the conveying transverse rigidity is required

when the choice yarn is a polyester monofilament as a skeletal layer of polyester fabric. Fabric structure by weaving style is plain, twill and straight through straight weft,

etc.

. To ensure that the cover layer and between the layers with good adhesion. Need to be activated or impregnated fabric processing. Bottom is lightweight belt transmission

surface, either supporting or roller support plate are in contact with the supporting material and transmission, usually skeleton fabric, and some light

Conveyor bottom layer is laminated and the cover layer or coating of the same material. Laminated material can be the same as or different from the coating. The thickness of the

light conveyor belt is generally 0. 5-4mm, between the thickness of not more than 7mm.
