One side of the two ends of the inside of the sterilization frame is hinged with a limited hinge rod, and one side of the top of the two groups of the limited hinge rods is provided with a groove. The above device can pull the telescopic plate out from the inside of the two groups of storage grooves through the mutual cooperation between the roller, the storage frame, the adjustment component, the telescopic plate, the storage groove, the rope and the third through groove, and the length of the conveying device can be adjusted.

However, the above-mentioned conveyor is not convenient for effectively reducing the production rate of oil bacteria on the circular conveyor belt during conveying operations, thereby ensuring the food safety of the circular conveyor belt during long-term use. On the other hand, it is not convenient to use the dynamic movement of the conveying equipment during food transportation to reduce the adhesion rate of fried food to the circular conveyor belt during transportation and to achieve rapid removal of excess oil on the fried food. At the same time, the existing device is not convenient for realizing personnel safety protection when the conveying mechanism performs conveying operations. Based on this, the present invention provides a safe conveying device for food processing to solve the problems raised in the above background technology. Summary of the invention

[0003] The present invention aims at the technical problems existing in the prior art and provides a safe conveying equipment for food processing to solve the problems that, on the one hand, the existing conveyor is not convenient for effectively reducing the production rate of oil bacteria on the circular conveyor belt during conveying operation, thereby ensuring the food safety of the circular conveyor belt during long-term use; on the other hand, it is not convenient to reduce the adhesion rate of fried food with the circular conveyor belt during transportation through the dynamic movement of the conveying equipment during food transportation and to achieve rapid removal of excess oil on the fried food. At the same time, the existing device is not convenient for achieving the problem of personnel safety protection when the conveying mechanism performs conveying operations.

[0005] The beneficial effects of the present invention are: 1. In the present invention, when the endless conveyor mesh belt rotates, the limiting roller and the cleaning brush shaft rotate slavedly. After the limiting roller and the cleaning brush shaft rotate slavedly, the spiral brush piece can repeatedly clean the outer surface of the endless conveyor mesh belt in a spiral manner layer by layer. The endless conveyor mesh belt is cleaned back and forth layer by layer, so as to effectively reduce the residual rate of oil stains on the surface of the endless conveyor mesh belt, and then effectively avoid the generation of oil bacteria on the endless conveyor mesh belt, thereby ensuring the food safety of the endless conveyor mesh belt during long-term use. At the same time, when the endless conveyor mesh belt rotates, the cam shaft rotates. After the cam shaft rotates, the reciprocating frame is driven to move back and forth in the vertical direction. Through the reciprocating movement of the reciprocating frame, the layout shape and layout angle of the endless conveyor mesh belt are reciprocated, and then the cleaning angle of the spiral brush piece to the endless conveyor mesh belt and the layout angle of the mesh holes on the endless conveyor mesh belt are reciprocated, thereby improving the sewage discharge of the endless conveyor mesh belt and the self-discharge effect of impurities in the mesh holes of the endless conveyor mesh belt.

[0006] 2. When conveying fried foods, the conveying equipment can realize synchronous axial reciprocating displacement and longitudinal reciprocating displacement of the fried foods conveyed on the annular conveyor mesh belt. The above-mentioned movement of the annular conveyor belt can effectively reduce the adhesion rate of the fried foods to the annular conveyor mesh belt during transportation and enable the excess oil on the fried foods to be quickly removed, thereby improving the de-oiling and oil recovery efficiency of the fried foods during transportation. In addition, the conveying equipment is provided with a safety protection component, thereby effectively improving the safety performance of the conveying equipment during use.

[0007] 3. When the present invention is used, the temperature data of the fried food conveyed on the circular conveyor mesh belt can be monitored in real time by setting a temperature sensor.

After the shaft shifting frame moves back and forth along the conveying direction of the annular conveyor mesh belt, the fried food transported on the annular conveyor mesh belt is shifted back and forth, thereby effectively reducing the adhesion rate of the fried food to the annular conveyor mesh belt during transportation. By reducing the adhesion rate, the integrity of the fried food after transportation is effectively guaranteed and the contamination rate of the annular conveyor mesh belt is reduced.

[0015] Furthermore, the longitudinal moving component includes a fixed transmission shaft and a circular shaft rotatably connected to the frame, and a movable shaft sleeve rotatably connected to the shaft shifting frame.
