It can be seen that the material moving mechanism 8 moves forward once, so that the purpose of moving the bean curd slices on all stations to the next station is achieved, in addition, the turning-over is realized in the moving process, and the whole process flow of material loading, double-sided frying and material discharging is completed by matching with the frying mechanism 7.

In the invention, the fan-shaped cover 805 is fixedly arranged between the parallel double racks 801 and is positioned on the coaxial line with the roller at the rear end of the first conveying belt 802, and the width of a gap left between the fan-shaped cover 805 and the surface at the rear end of the first conveying belt 802 is slightly larger than the thickness of the bean curd slices, so that the bean curd slices can fall into the fan-shaped cover 805 in sequence and turn over is completed. In order to improve the conveying effect, the lower edge of the fan-shaped cover 805 is close to a horizontal angle, and the inner surface of the fan-shaped cover 805 can be lubricated to avoid the phenomena of pause, extrusion and damage of the bean curd slices.

To this end, in a preferred embodiment, the present invention further modifies the structure of blade 804 as follows:

two sides of the shovel plate 804 are rotationally connected with the parallel double racks 801 through the protruding shaft 808, the protruding shaft 808 and the front end roller of the first conveyer belt 802 are coaxially arranged, the outer ring of the protruding shaft 808 is connected with an outer shaft sleeve 809 in a damping rotation (capable of rotating but with certain rotational resistance), the parallel double racks 801 are also provided with a second roller 810 which is in rolling connection with the double gear rails 2, and the second roller 810 is connected with the outer shaft sleeve 809 through a conveyer belt; based on the design, the material moving mechanism 8 moves back and forth in a reciprocating manner, when the material moving mechanism 8 moves forward along the double-tooth rail 2, the second idler wheel 810 rolls along the double-tooth rail 2, and simultaneously the outer shaft sleeve 809 drives the protruding shaft 808 to rotate, so that the shovel plate 804 rotates until the edge of the front end faces downwards and contacts with the surfaces of the stations of the platform 1, and shoveling is realized; when the material moving mechanism 8 moves backwards along the double-tooth rail 2, the second roller 810 rolls along the double-tooth rail 2, and simultaneously the protruding shaft 808 is driven to rotate through the outer shaft sleeve 809, so that the shovel plate 804 rotates until the edge of the front end faces upwards and is separated from the surfaces of all stations of the platform 1, and the bean curd sheets are prevented from being disturbed when moving backwards. Moreover, because the protruding shaft 808 is connected with the outer shaft sleeve 809 in a damping rotation manner, when the shovel 804 contacts with the surface of the platform 1 or is attached to the first conveyor belt 802, the shovel 804 does not rotate any more, and the movement of the material moving mechanism 8 is not influenced to drive the second roller 810 to rotate; in addition, when the shovel plate 804 moves forward, a downward pressure is always provided, so that the shovel plate 804 is always tightly attached to the surface of the platform 1, and the shoveling effect is improved.

In the invention, the front end of the shovel plate 804 is in a tip shape, which is beneficial to improving the shoveling effect, and the rear end of the shovel plate 804 is in an arc shape matched with the front end roller of the first conveying belt 802, so that a space for adjusting the shovel plate 804 to rotate up and down can be provided.

In the process of frying by the frying mechanism 7, oil is required to be supplied continuously, sufficient edible oil is generally required to be supplied during frying, and the edible oil is remained after the frying is finished, so that the remaining edible oil can influence the shoveling and conveying of the bean curd sheets, the later-stage packaging and eating taste are also influenced, and the edible oil is wasted. To this end, the present invention provides a further improvement to the frying mechanism 7:

the frying mechanism 7 comprises a frying box 701 fixed on the platform 1, an electric heating plate 702 flush with the surface of the platform 1 is arranged on the top surface of the frying box 701, resistance wires are arranged in the electric heating plate 702, micropores are uniformly distributed, a movable plate 703 is transversely arranged in the frying box 701, oil absorption fibers 704 are filled in a cavity above the movable plate 703, the frying mechanism 7 further comprises an oil storage box 705, the oil storage box 705 is communicated with the cavity above the movable plate 703 through an oil pipe, a one-way valve 706 for preventing oil return is arranged on the oil pipe, when the movable plate 703 is moved upwards to an oil supply position, the oil in the oil absorption fibers 704 is extruded to pass through the micropores of the electric heating plate 702 to reach the surface of a station, when the movable plate 703 is moved downwards to the oil absorption position, the oil absorption fibers 704 suck back redundant oil on the surface of the station, and simultaneously suck a certain amount of oil in the oil storage box through the oil pipe to supplement the 705, and prepare for next oil supply.

In order to simplify the driving of the movable plate 703 and to achieve complete adaptation of the oil supply and oil absorption processes to the moving process of the moving mechanism 8, the matching problem is avoided. The invention preferably comprises the following components: the outer side edge of the front end of the parallel double frame 801 is rotatably connected with a push rod 811 and a limit block 812 for limiting the push rod 811 from rotating backwards, the bottom surface of the movable plate 703 is supported by a plurality of elastic members 707, the movable plate 703 is provided with an extension plate 708 extending out of the side surface of the frying box 701, and the extension plate 708 is positioned on a moving path of the push rod 811 (naturally drooping by the push rod 811 under the action of gravity) moving along with the material moving mechanism 8.

When the material moving mechanism 8 moves forward to the first frying station 4 or the second frying station 5 along the double-tooth rail 2, the first frying station 4 is taken as an example for explanation: when the shovel plate 804 on the material moving mechanism 8 reaches or is about to reach a critical line between the feeding station 3 and the first frying station 4, the push rod 811 contacts with the station extension plate 708, the push rod 811 cannot rotate backwards due to the limiting effect of the limiting block 812, so that the extension plate 708 is pushed to move downwards, the movable plate 703 is further moved downwards to an oil absorption level, and the residual edible oil on the surface of the first frying station 4 is absorbed back into the oil absorption fiber 704, so that when the shovel plate 804 shovels along the surface of the first frying station 4, the fried bean curd slices do not carry a large amount of edible oil, the drying performance in the conveying process is facilitated, the edible oil is saved, and the mouthfeel is improved; in addition, the length of the extension plate 708 is such that when the shovel plate 804 shovels along the surface of the first frying station 4, the movable plate 703 does not move upwards and is always located at the oil suction level; when the material moving mechanism 8 moves forward along the double gear rails 2 away from the first frying station 4, the push rod 811 disengages from the extension plate 708, the movable plate 703 of the station moves upward to the oil supply level through the elastic member 707, and the surface of the first frying station 4 is replenished with new cooking oil to prepare for the next frying. When the material moving mechanism 8 moves backward along the double gear rails 2, the push rod 811 is blocked by the extension plate 708 and can rotate forward and stagger, so that the extension plate 708 is not pushed to move downward, the movable plate 703 keeps the oil supply level, and the frying process is not affected.

In the present invention, the rear end of the extension plate 708 is formed with an inclined surface for sliding contact with the push bar 811, so as to facilitate the downward movement of the extension plate 708, and the front end of the extension plate 708 is formed with a vertical surface for blocking the push bar 811.

In the invention, the platform 1 is provided with a second driving member for driving the material moving mechanism 8 to move along the double-tooth rail 2, and the preferred embodiment has the function of linear reciprocating driving. One of the structures of the second driving piece is as follows: the double-rack-type electric bicycle comprises a second motor 9 and a second threaded rod 10 arranged at the output end of the second motor 9, wherein the second threaded rod 10 is arranged in parallel with the double rack rails 2 and is in threaded connection with the parallel double racks 801. In operation, the second driving member is controlled by the controller to drive the material moving mechanism 8 to move back and forth once at set time intervals, for example, 3 minutes is set, namely, the material is moved once every 3 minutes, and the frying time of each surface of the bean curd block is also 3 minutes.

In the invention, the discharging station 6 is a rectangular gap, and a collecting box 601 is arranged below the rectangular gap. In addition, the double-tooth rails 2 with certain length are still reserved at the front end of the discharging station 6, so that the material moving mechanism 8 can convey all the bean curd blocks to fall. After the material moving mechanism 8 moves the second frying station 5 to the discharging station 6, the bean curd blocks fall into the collection box 601 to be collected, and the collection box 601 is used for collecting the fried bean curd blocks for the packaging device 12.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is specific and detailed, but not to be understood as limiting the scope of the present invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
