The connection between the main components of the vacuum packing machine and the transport plane
The connection between the main components of the vacuum packing machine and the transport plane. The construction of vacuum packaging machine and other equipment are also different. Traction members (special chains or, in rare cases, wire ropes) are flexible in both horizontal and vertical directions, so the suspension conveyor can have spatial wiring, i.e. arbitrary steering in both horizontal and vertical planes. The steering of the traction member in the horizontal plane is carried out by using the steering wheel or the steering sprocket or the roller group. The steering in the vertical plane is carried out using the guide rail. Pneumatic vacuum packaging machine in the packaging process will have the role of vacuum inflation, with other vacuum packaging machine is also different.
The connection between the main components of the vacuum packing machine and the transport plane. As the traction component of the suspension conveyer arranged in the same horizontal plane (i.e., no bending in the vertical direction), various types of ordinary traction chain or wire rope can be used. For spatial transport, traction members are required to have a certain degree of flexibility in the two planes. Therefore, various detachable chains, welded chains made of round steel, special slice chains and double-joint chains of various structures, as well as various wire ropes are applied. The simple and reasonable traction component used in suspension transport is detachable chain, which has been widely used. Automatic packaging machine can achieve automatic packaging equipment, packaging efficiency is relatively high.
The connection between the main components of the vacuum packing machine and the transport plane. Less use is made of welded chains. It is only used in light transport aircraft, especially where small radius is required for vertical bending. The difference between the special type chain and the ordinary chain lies in: the clearance between the circular shaft and the bushing is large (up to 1mm along the radius direction) and the clearance between the bushing and the outer chain piece is also large; The chip chain is larger in weight and higher in price than the folding chain.
The connection between the main components of the vacuum packing machine and the transport plane. In order to find the radius of small vertical bending, a lot of double-joint chains with different structures are designed. Vertical and horizontal joint chains (i.e., universal chains) are one of them. A conveyer with a small bending radius (about 1.2m) and a vertical lift and fall can also be made by using a double chain with universal direction and a rigid triangular joint suspension (or suspension rod). The conveyer is sometimes used as a standard wire rope for the traction members of the suspension conveyer, usually 12.5~13mm in diameter and made of steel wire with a diameter of 0.5~1.0mm.
The connection between the main components of the vacuum packing machine and the transport plane. The basic type of suspension conveyer is a crane. The utility model comprises a roller with a shaft and a bearing, a bracket on which the roller is fixed, and a fork for fastening the chain to the bracket and the suspension of the material. The car is used to support the suspension (or transverse) of the material and make it move along the suspended road (working car or transverse car), or to support the chain to prevent it from having too much sag between the suspension (non-working car) the roller of the car is cast of cast iron or made of steel stamping. In order to extend the service life of the roller, the hardness of its periphery must be increased.
The connection between the main components of the vacuum packing machine and the transport plane. The profile around the roller is determined by the profile of the track running surface, which is usually conical when driving along i-bars, and cylindrical when driving along angles or flat bars. The conical roller will cause little additional friction loss when rolling, but it can ensure the stable position on the inclined flange of i-steel. Roller with rim and rim of the two, generally use the latter one. The structure of the bearing parts of the roller is varied according to the type and size of the bearing and the characteristics of the dustproof sealing device.
