A spiral tower conveyor

Abstract

The invention relates to a spiral tower conveyor. The mesh chain is spirally wound around the outer periphery of the rotating drum and rotates synchronously with the rotating drum. The inner edge of the driving head is in a convex arc shape, with arc grooves on both sides or one side, and the driving vertical rods are evenly distributed on the outer periphery of the drum and meshed with the driving heads of each layer; the bottom of each layer of mesh chains are respectively The support slides on the spiral ring rail, and the spiral ring rails of each layer are respectively fixed on the radial support rods, and each radial support rod is fixed on the column, and each column is evenly distributed around the axis of the drum. The net chain enters the arc spiral section from the straight line through the turning transition section. The outer side of the net chain in the turning transition section forces the loose inner side of the net chain to adjust its position so that the inner side adapts to the circumference of the outer side. The drive pole engages. The conveyor's network chain runs smoothly and turns smoothly, and can keep moving forward smoothly in a slack state.

Description

technical field [0001] The invention relates to a conveyor, in particular to a spiral tower conveyor, which belongs to the technical field of conveying equipment. Background technique [0002] The baked food production line needs to use high temperature to bake the food. The high temperature food taken out of the oven cannot be packaged immediately, and needs to be cooled and transported for a long time. The food is completely cooled before being packaged. The spiral tower conveyor provides a long conveying distance in the case of a small footprint, so that a longer cooling time can be obtained, so it has been widely used in the food baking industry. [0003] The existing spiral tower conveyor has the following deficiencies: 1. When the network chain enters the turning transition section from the straight line, the inner side of the network chain needs to be close to each other to adapt to the change of the outer circumference. The meshing of the transition section is not s...

Problems solved by technology

[0003] The existing spiral tower conveyor has the following deficiencies: 1. When the network chain enters the turning transition section from the straight line, the inner side of the network chain needs to be close to each other to adapt to the change of the outer circumference. The meshing of the transition section is not smooth, or when the inner side of the network chain has not adapted to the change of the outer perimeter, the drive head engages with the drive pole in advance, so that the inner side of the network chain is limited by the reverse limit of the drive rod, and the straight line travels to the inner side of the turning transition section. The traction of the chain is limited, and the continuous unadapted accumulation on the inside of the chain will make the length of the outside of the chain less than the theoretical circumference, making the outside of the chain tight

[0005] 2. The rotation of the drum is usually achieved by the main drive sprocket driving the drum sprocket through the chain. Since the transmission ratio between the main drive sprocket and the drum sprocket is relatively large, the transmitted load is also relatively large. The main drive chain Tooth jumping is easy to occur between the wheel and the chain, which affects the stability of the equipment

[0006] 3. Because the length of the net chain is relatively long, there is usually a tensioning device. The floating of the counterweight device not only compensates for the length of the net chain, but also exerts an additional drag force on the net chain; and the beating of the counterweight Bringing a large impact load to the mesh chain, it is easy to cause impact movement and deformation and fracture, and it will increase the friction between the mesh chain and the support rail.

[0007] 4. According to the needs of the process, sometimes it is necessary to use two towers for conveying. Because the conveying distance is too long, especially when it is wound on the second tower from the transition section, it is easy to cause synchronization errors between the two towers, and the tightness of the network chain is inconsistent. There is no guarantee that the network chain is always in a stable slack state
