With the economic development of the increasingly high demand for the environment, the tube with a machine as a closed transport of materials, more and more widely used to various occasions. Now with a basic knowledge of tube machine to do a brief introduction:

First, the structural characteristics:

   Tape machine is a hexagonal arrangement of the roller to force the edge of the tape wrapped around each other into a circular tube to convey the material of a new belt conveyor. The head, tail, receiving point, unloading point and tensioning device of the pipe belt machine are basically the same as those of the ordinary belt conveyor. Conveyor belt at the end of the transition section after receiving, and gradually rolled into a circular tube-shaped material for closed delivery, to the head transition section and then gradually open until the discharge. The detailed structure of the pipe machine is shown in the following figure: It is composed of drive equipment and drive roller, tailstock, screw tensioning device, steering roller, transitional frame, belt, pillar, truss, support stick, walkway, hexagonal roller Group, the level of rewinding equipment, the center rack, tower and other components. Conveyor belt at the end of the transition section after receiving, and gradually rolled into a circular tube-shaped material for closed delivery, to the head transition section and then gradually open until the discharge.

Second, compared with belt conveyor belt conveyor strengths

   1, environmental protection superior performance

   Material completely sealed by tape, will not leak, thus, transport block, powder, toxic and dust from the material will not form environmental pollution.

   2, small radius bending advantage

   Compared with other belt conveyors, one of the main advantages of the tube is a small radius of twists and turns. For most applications, this advantage is the most important, when the sharp change in the direction of transport, do not need to set transit points. The rollers are looped around the conveyor belt, which can twist in any direction. Twists and turns can be in the horizontal plane, straight and even together in the level of the two straight face. Eliminating the transfer point, but also eliminates the need for additional rollers, hopper, dust collector, and thus significantly reduce the loss of materials. The most important thing is to avoid the transfer point of protection. Tubing machine can have multiple zigzag section, so a tube with a machine can replace multiple general-purpose belt conveyor and the forwarding point and additional equipment.

   3, large-angle tilt function

   Compared with the general belt conveyor, the belt conveyor has a larger inclined conveying angle. The circular cross section increases the contact area between the material and the conveyer belt, increasing the transport angle by 50% and up to 27 °. The greater the tilt angle, the shorter the length of the conveyor, the more economical. So that the tube into the machine in the space and functional limitations of only a feasible material handling solutions.

   4, the return belt into a round tube

   The conveyor belt can also be designed as a round tube, with the conveyor belt rolled up and some of the bottom of the tube in the loop, which not only makes the same conveyor belt with the same side of the tortuous road, but also dirty conveyor belt One side is wrapped up, the possibility of material dripping very small.

   5, the same amount of transport and general-purpose belt conveyor

   Tube conveyor with the general, with the bandwidth of its diameter 2.5 to 3 times the same as the general belt conveyor. For example, a 300mm (12in) tube conveyor is the same as a conventional belt conveyor with a belt width of 800mm (30in), a roller angle of 20 °, and a discharge angle of 20 °, and a tubular belt type Conveyor stands are only 635mm (25 in) wide, with a minimum of 1 050mmn (41in) wide for universal belt conveyors. In the conveyor equipment space restricted by the tunnel, the use of tubular belt conveyor can reduce the tunnel cross-section.

   6, the use of standardized components

   The pipe belt machine can use the same standard parts as the general belt conveyor. Because the belt conveyor belt is flat in the head, tail and tensioning roller, and belt speed series are common, so you can use the standard universal belt conveyor roller, bearing and drive equipment

   7, the upper and lower travel can be transported together

   As with the general belt conveyor, the pipe conveyor with the upper transport material, the next trip can also be transported material. In order to transport the material in the backhaul, it is necessary to turn the conveyor 180 ° so that some of the overlap is on top and the dirty side of the conveyor is still facing inward. No need to add roller and drive equipment, 1 tube with machine than 2 general-purpose belt conveyor economy.

Third, the belt machine debugging

   After the installation of the equipment with the pipe end, you can carry out no-load debugging. Check the operation status of the reducer, motor, roller, belt and other equipment, record the heat and vibration of reducer, motor and drum. Special attention should be paid to check the belt section over the operation of the situation, to see the overdue section of the flat belt can be rolled into a tubular belt, the tubular belt into a flat belt, as the tube or flattening is not ideal, to adjust the overdraft care stick, Belt overlap Some are not in the upper six PSK roller, to adjust the PSK roller.

   After commissioning:

   1, the belt coincidence must be in the upper six PSK roller.

   2, tubular belt does not occur snake turn.

   3, PSK care stick with the belt in good contact.

   4, reducer, motor vibration, temperature rise to reach the requirements.

   5, start and stop, tighten the normal operation of equipment, tape, no slip phenomenon.

   6, there is no scratch tape and not allowed the existence of conflict.

   7, feeding, all rollers should be sensitive to rolling.

   8, bearing temperature rise should be stable, sliding bearing temperature <65 ℃, rolling bearing temperature <80 ℃.

   9, bearing and rolling without exception.

   10, no oil, oil phenomenon.

   11, the control system is accurate, operating sensitive operation.

   12, output to reach specification.

   13, interlock and the terminal button is normal.

   14, guide trough rubber skirt and tape the gap between the right.

   15, the fluid coupling without heating phenomenon.
