The spiral mesh chain conveyor provides a long conveying distance under the condition of small occupied area, so that longer cooling time can be obtained, and the spiral mesh chain conveyor is widely applied to the food baking industry.
The existing spiral type net chain conveyor comprises a rotary drum, a net chain is spirally wound on the periphery of the rotary drum and synchronously rotates along with the rotary drum, a rotary drum central shaft is arranged at the center of the rotary drum, and the upper end and the lower end of the rotary drum central shaft are respectively supported on a rack through bearing seats; the bottom of each layer of net chain is supported on the spiral ring rail to slide, each layer of spiral ring rail is fixed on the radial support rod, the outer end of each radial support rod is fixed on the stand column, and the stand columns are uniformly distributed by taking the axis of the rotary drum as the center.
The existing spiral type net chain conveyor has the following defects: 1. the net chain directly enters the arc-shaped limiting guide section for forced steering from the straight line advancing section, and all pin shafts of the net chain are changed into a fan-shaped opening state with the outer side spacing larger than the inner side spacing from a mutually parallel state. In this process, the inner sides of the net chains need to be close to each other to adapt to the change of the outer circumference.

2. Because the frame is the welding piece, the bearing frame at rotary drum center pin both ends is difficult to guarantee than higher concentricity, and can not guarantee with the straightness that hangs down on ground.
