Grouping manner and in accordance with the number of layers required to complete the bag , plastic blocks , box palletizing and other products . Optimized design makes the stack tightly , neatly.2 Characteristics and Principles2.1Features Coal belt conveyor is ideal for efficient continuous transport equipment , compared with other transport equipment ( such as locomotive class ) , has the advantage of long distance transportation , large volume, continuous conveyor , etc., and reliable operation, easy to automate and centralize control , especially for high-yield and efficient mine , coal mining conveyor has become mechatronics technology and equipment critical equipment . The main feature is the body belt conveyor can easily scalable with belt storage , tail can advance with the coalface elongation or shortening , compact, not to set the foundation , laid directly on the roadway floor , rack lightweight, very easy disassembly . When the transmission capacity and transport distance is large, can be equipped with an intermediate drive to meet the requirements. According transport process requirements , can be stand-alone transport , but also multi- level synthesis unit or inclined transportation system to transport materials . Belt Conveyor is widely used in metallurgy, coal , transport , utilities, chemical and other sectors , because it has a transmission capacity, simple structure, easy maintenance , low cost , versatility , etc. . Conveyor is also used in building materials , electricity, light industry, food , ports , shipbuilding and other sectors. Stacking machine structural characteristics : in low stacking machine is mainly composed of flattened conveyor, slow stop conveyor , transfer conveyor , pallet warehouse , pallet conveyors, grouping machines, pushing bag device , palletizing equipment , transport pallets machine. Its structural design optimization, smooth and reliable action. Palletizing process is completely automatic , without human intervention during normal operation , has a wide range of applications.2.2 Work Mainly by the belt conveyor belt , drive roller , tensioning device , roller racks and gear parts and other components . After the tape around the ends of the drum by using tape clamp or curing method, the two together to make it a closed loop structure. Tape from the upper and lower supporting rollers , the tape tensioning the tensioning means , with a certain tension. When the driving motor rotates the drum is driven by means of drive rollers and the friction between the tape with a tape of continuous operation , which will be installed on the carrier tape to unload cargo unloaded from the drum 2 . Layer of the workpiece and the workpiece flat on the pallet stacking machine meets the requirements of flat workpieces move forward until the pallet vertical . Top of the gauge rod drop , another tripartite positioning clamping lever start , then flat reset. Each piece down to the pallet flat , flat underside and away from the plane pallet 10mm, drop a workpiece pallet height . Back and forth until the pallet stacking above reaches the set requirements.2.3 Transmission Principle Features 1.traction belt conveyor is through friction between the drive pulley and the belt to pass , it must be the tape taut with tension device , so that the tape has a certain tension in the early separation of the transfer drum roller . 2. tape together with cargo runs on rollers . Tape as the drag mechanism , and a loading mechanism , there is no relative movement between the cargo and the tape , the tape running and eliminating the friction cargo . Since built with roller bearings, rolling friction between the tape and rollers, thus greatly reducing the running resistance , thereby reducing power consumption , increasing the transport distance . For a conveyor belt, the size of its traction transmission capacity , the decision of the coefficient of friction between the belt tension on the drive belt drum circumference tape wrap angle and the drive roller . To ensure the belt conveyor belt does not slip on the drive roller , normal operation , to take appropriate measures in the production practice under different circumstances . Improve traction transmission capacity available from the following aspects: increasing tension force ( initial tension ) . Belt Conveyor in operation, the tape to stretch , resulting in decreased traction , so depending on the circumstances , the use of the tape tensioning device properly tensioned belt tension is increased to improve traction. increase the coefficient of friction. The specific measures are: to protect the well -covered wood lining the drive roller or rubber pads to increase the coefficient of friction , on the other hand less water coal, preventing friction coefficient decreases. increase Wai corners . Because mine belt conveyor poor working conditions , the required traction , so many dual drum drive to increase Wai corners .3 Conveyor3.1 Technical advantages The first is its reliable operation. In many important production units require continuous operation , such as the transport of coal power plants conveying bulk materials steel mills and cement plants , as well as loading and unloading of ships in the harbor , are using belt conveyors . On these occasions , such as shutdown , the loss is huge. When necessary, the belt conveyor can take a class to a group of continuous work . Conveyor low power consumption . Due to the material and almost no relative movement of the conveyor belt , not only the running resistance is small ( about 1/3-1/5 scraper conveyor ) , but also for cargo wear and crushing are small , high productivity . These are conducive to lower production costs.Transport conveyor line adaptable and flexible. Line length according to the need. As short as a few meters , length up to 10km or more. Can be installed in a small tunnel above the ground can also be set up in the traffic chaos and danger areas. According to process requirements , can be very flexible conveyor from the feed point or points by . You can also multi-point or a few sections to discharge . When both the feed ( coal preparation plant conveyor position under ) or at several points along the length direction of the conveyor belt according to any point on the conveyor through the feed device to a uniform feed conveyor , belt conveyor machine has become a major transport trunk . You can stockpile conveyor roadway below reclaimer at coal storage field , when needed , but also the various different materials mixed heap . Material may be simply discharged from the head of the conveyor , can also be moved or plow unloader unloading vehicle longitudinal direction at any point of the discharge conveyor .3.2 Design Points 1, the working environment , conditions and conditions Need to consider the time of day operation , the operating frequency , the service life of the belt conveyor , feeding and unloading methods .Work environment conditions : ambient temperature, outdoor or indoor , environmental requirements, mobile or fixed , telescopic requirements. 2 , transmission lines and conveyor problems Requires detailed consideration of the size of the transfer line , comprising: a tilt angle , the maximum length , lifting height ; straight segment , the size of the curve segment ; connection size.Conveyor belt: the maximum sag requirements simulation of friction coefficient , friction coefficient, the safety factor. 3 , the nature and amount of material transported The specific nature of the materials to be considered , including : bulk density , angle of repose , the material particle size , the largest block , the humidity of the material , abrasion resistance, adhesion and coefficient of friction material.
