the double-rack 2 is provided with a material moving mechanism 8, the material moving mechanism 8 comprises a parallel double-rack 801, a first conveying belt 802 and a second conveying belt 803 which are arranged between the parallel double-rack 801, the first conveying belt 802 is positioned in the front end direction, the front end of the first conveying belt 802 is provided with a shovel plate 804, the shovel plate 804 can be in surface contact with the platform 1, the rear end of the first conveying belt 802 is provided with a fan-shaped cover 805, the front end of the second conveying belt 803 is positioned below the rear end of the first conveying belt 802 to form partial overlapping in the height direction, the first conveying belt 802 and the second conveying belt 803 are linked through a conveying belt, the parallel double-rack 801 is provided with a first idler wheel 806 and a reversing wheel 807 which are meshed with each other, the parallel double-rack 801 is in rolling connection with the double-rack 2 through the first idler wheel 806, and the reversing wheel 807 is linked with the first conveying belt 802 or the second conveying belt 803 through the conveying belt; when the material moving mechanism 8 moves forward along the double-tooth rail 2, the first roller 806 rolls along the double-tooth rail 2, and simultaneously drives the first conveyor belt 802 and the second conveyor belt 803 to rotate through the reversing wheel 807, the shovel plate 804 at the front end of the first conveyor belt 802 shovels along the surface of each station, sequentially shovels the bean curd on the surface of each station, and after the bean curd is conveyed through the first conveyor belt 802, falls off through the turnover of the fan-shaped cover 805, and is conveyed through the second conveyor belt 803, falls to the next station.

It should be noted that, the height difference between the first conveyor belt 802 and the second conveyor belt 803 and between the second conveyor belt 803 and the surface of the platform 1 is small, and is slightly larger than the thickness of the skin of soya-bean milk, so that the skin of soya-bean milk is not turned over during the dropping process, and the skin of soya-bean milk is prevented from being stacked. In addition, in order to match the conveying process of the bean curd sheets on the conveyor belt with the moving process of the material moving mechanism 8 on each station, the front-back width of the material moving mechanism 8, the total conveying path length of the conveyor belt and the conveying speed need to be set adaptively, for example, the front-back width of the material moving mechanism 8 is set to be equal to the front-back width of each station, the total conveying path length of the material moving mechanism 8 is set to be twice the front-back width of each station, and the conveying speed is equal to the moving speed of the material moving mechanism 8.

During operation, the cut bean curd sheets are placed on the feeding station 3, the material moving mechanism 8 is located at the rear end of the feeding station 3 and moves forward, and during the moving process, the first roller 806 can rotate clockwise (referring to the view angle of fig. 3) under the action of the double rack rails 2, so that the reversing wheel 807 and the first and second conveying belts 802 and 803 are driven to rotate anticlockwise; when the shovel plate 804 shovels the bean curd sheets on the feeding station 3, the bean curd sheets are conveyed backwards by the first conveyor belt 802, at the rear end of the first conveyor belt 802, the bean curd sheets are turned over and fall onto the surface of the second conveyor belt 803 by the action of the fan-shaped cover 805 to be conveyed backwards continuously, and finally fall off the second conveyor belt 803, in the process of conveying the bean curd slices backwards, the material moving mechanism 8 continuously moves forwards, when the shovel plate 804 reaches the critical line between the feeding station 3 and the first frying station 4, the bean curd slices on the feeding station 3 are all scooped up, at the moment, the scooped bean curd slices just occupy half of the conveying path of the conveying belt in the material moving mechanism 8, when the material moving mechanism 8 continues to move forward, the shoveling plate 804 shovels the bean curd sheets on the surface of the first frying station 4, and the same is conveyed backward, when the shovel plate 804 reaches the critical line between the first frying station 4 and the second frying station 5, the fried tofu pieces on one side of the first frying station 4 are all shoveled, at this time, the half way of the upper rear end of the conveyor belt of the material moving mechanism 8 is the tofu piece raw material on the feeding station 3, while the half of the front end is the bean curd slices on one surface which are already fried on the first frying station 4, the material moving mechanism 8 continues to move forwards, the half of the rear end, namely the bean curd slice raw material which is scooped up by the feeding station 3, just begins to fall to the first frying station 4, the scooping plate 804 also gradually scoops up the bean curd slices which are both fried on the two surfaces on the second frying station 5, when the shovel plate 804 reaches the critical line between the second frying station 5 and the discharging station 6, the whole of the bean curd slices fried on both sides of the second frying station 5 are shoveled, the bean curd slice raw material provided by the feeding station 3 is laid on the first frying station 4, the bean curd slices on one side fried in the first frying station 4 are positioned on the rear half of the upper end of the conveyor belt; the material moving mechanism 8 continues to move forwards, the fried bean curd slices on one side gradually fall to the second frying station 5 after being turned over until the second frying station 5 is completely paved, and at the moment, the two fried bean curd slices on the front side and the back side of the second frying station 5 are positioned in the half-way of the upper back end of the conveyor belt; the material moving mechanism 8 continues to move forwards, and the fried bean curd slices on the two sides are discharged from the discharging station 6. It can be seen that the material moving mechanism 8 moves forward once, so that the purpose that bean curd slices on all stations move backward is achieved, in addition, the turning-over is achieved 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 frames 801 and is positioned at the position coaxial 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 bean curd sheets, so that the bean curd sheets 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.

In the invention, when the material moving mechanism 8 moves forwards, the shoveling plates 804 need to be shoveled along the surface of the platform 1, which is not beneficial to the resetting of the material moving mechanism 8, and the double-tooth rails 2 need to be arranged annularly, which undoubtedly greatly increases the floor area of the equipment and is not beneficial to driving. 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 protruding shafts 808, the protruding shafts 808 and front end rollers of the first conveying belt 802 are coaxially arranged, outer rings of the protruding shafts 808 are connected with outer shaft sleeves 809 in a damping rotation mode (capable of rotating but with certain rotation resistance), the parallel double racks 801 are further provided with second rollers 810 in rolling connection with the double gear rails 2, and the second rollers 810 are connected with the outer shaft sleeves 809 through the conveying belts; 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-toothed rail 2, the second roller 810 rolls along the double-toothed 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 upwards and is separated from the surfaces of the stations of the platform 1, and the bean curd slices 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 frying process of the frying mechanism 7, oil needs to be supplied continuously, sufficient edible oil needs to be supplied generally during frying, and the edible oil can be remained after the frying is finished, so that the remained edible oil can influence the shoveling and conveying of the bean curd skin, the later-stage packaging and eating taste, 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 box body 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 box body 701, resistance wires are arranged in the electric heating plate 702, micropores are uniformly distributed, a movable plate 703 is transversely arranged in the box body 701, oil absorption fibers 704 are filled in a cavity above the movable plate 703, the frying mechanism 7 further comprises an oil storage tank 705, the oil storage tank 705 is communicated with the cavity above the movable plate 703 through oil pipes, a one-way valve 706 for preventing oil return is arranged on each oil pipe, when the movable plate 703 is moved upwards to an oil supply position, the edible 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 supply position, the oil absorption fibers 704 suck back redundant edible oil on the surface of the station, meanwhile, a certain amount of edible oil in the oil storage tank is sucked through the oil pipes for supplement, and preparation is made for next oil supply 705.

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 box 701, and the extension plate 708 is positioned on a moving path of the push rod 811 (naturally drooping by the action of gravity of the push rod 811) 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 shoveling 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 to facilitate 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, a driving part is arranged on the platform 1 and used for driving the material moving mechanism 8 to move along the double gear rails 2, and the platform has the function of linear reciprocating driving in the preferred embodiment. One of the structures of the driving piece is as follows: the double-rack type double-rack driving device comprises a motor 9 and a threaded rod 10 arranged at the output end of the motor 9, wherein the threaded rod 10 is arranged in parallel with the double racks 2 and is in threaded connection with the parallel double racks 801. In operation, the 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 collecting box 601 to be collected, so that subsequent quality inspection and packaging are facilitated.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed 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.
