[0016] Compared with the prior art, the utility model has the following advantages:

[0017] (1) The utility model can realize automatic frying of bean curd skin, realize automated production, get rid of manual production, effectively improve production efficiency, and ensure frying quality. Specifically, the bean curd skin is placed on the feeding tray manually or mechanically. Because the two groups of feeding mechanisms are symmetrically arranged, only one worker or one device is needed between the two groups of feeding mechanisms to place the bean curd skin on the feeding tray. The feeding tray is then driven by the feeding assembly to move to the skewers. The skewers are just inserted into the feeding tray from the inlet, and the bean curd skin is just located between the two skewers. Then, the skewers are driven by the longitudinal assembly to move downward from the outlet to move out of the feeding tray. One end of the bean curd skin is folded in half and moved downward to the oil pan under the drive of the skewers to start frying. Moreover, the skewers are driven by the transverse assembly to move to the right to ensure that the frying is fully carried out. At the same time, the skewers are kept fixed to the bean curd skin so that the bean curd skin can be picked up after frying, thereby completing the entire frying operation of the bean curd skin.

[0018] (2) The utility model can complete the automatic rolling process of the bell roll, with high production efficiency and good product uniformity. The bean curd skin is processed into the bell roll immediately after being fried, and the bell roll is made before the bean curd skin is cooled to ensure that the bean curd skin can remain in a rolled state after cooling, thereby providing a bell roll with excellent appearance. Specifically, one end of the bean curd skin is folded in half and fixed between two skewers to ensure that the skewers can drive the bean curd skin to move. When rolling, the skewers first move toward the de-oiling plate, and the bean curd skin is clamped between the skewers and the de-oiling plate, and After that, the transverse component cooperates with the longitudinal component to drive the skewer to move upward along the de-oiling plate, and spread the bean skin flat on the de-oiling plate. Because the bean skin is fixed on the skewer by folding in half, the skewer does not have a clamping force on the bean skin. Therefore, in order to prevent the bean skin from detaching from the skewer when the skewer drives the bean skin to move upward, the de-oiling plate is used to receive the bean skin to prevent the bean skin from detaching from the skewer, and the oil on the bean skin can flow back to the oil pan along the de-oiling plate. Then, the rotating component drives the skewer to rotate. Because one end of the bean skin is fixed on The rotation of the skewer will drive the bean curd skin to roll, thereby completing the rolling of the bell roll, and because the skewer is in contact with the de-oiling plate, the skewer will also generate an extrusion force on the bean curd skin during the process of rolling the bean curd skin, squeezing out the oil in the bean curd skin, thereby ensuring the efficient and oil-free production of the bell roll. In addition, the utility model can ensure that the bell roll is well kept in a rolled state before it is completely cooled, thereby ensuring that the produced bell roll is of good quality and consistent in appearance. Specifically, the bean curd skin is immediately processed into a bell roll after frying, and the bell roll is made into a bell roll before the bean curd skin is cooled, and then sent to between the two opened barrel sheets. When it is transported to the right place, the finger cylinder controls the two barrel sheets to close, and fixes the bell roll between the two barrel sheets. The circular cavity formed by the two barrel sheets can well keep the bell roll in a rolled state, so as to ensure that the bean curd skin can remain in a rolled state after cooling, thereby providing a bell roll with excellent appearance, and then, the third driver drives the two barrel sheets to move out, and the finger cylinder controls the two barrel sheets to open, and transports the bell roll out;

[0019] (3) The utility model also provides a structure for salvaging residues and unqualified bell rolls. Since the skewers do not have a clamping force on the bean curd, the bean curd may fall during the frying process. In order to salvage the fallen bean curd in time and avoid over-frying, the utility model provides a sensor at the de-oiling plate to sense whether there is bean curd on the skewers moving there. If the bean curd falls, the sensor cannot detect the bean curd and transmits a signal to the controller. The controller controls the scooping net assembly to salvage the fallen bean curd. In addition, the scooping net can be automatically dumped. Specifically, in the initial state, the scooping net is located at the front side of the oil tank. When the scooping net moves from front to back for salvaging, it moves to the end. At this time, the movable side plate is located at the bottom plate. The front side of the scoop net moves upward out of the oil tank, and the rotator drives the scoop net to rotate counterclockwise. Because the movable side plate is slidably mounted on the bottom plate, when the bottom plate rotates, the movable side plate will move from front to back, and while completing the reversal, the residue on the bottom plate will be discharged, thereby completing the salvage. When the sensor cannot detect the bean skin again, at this time, the scoop net located at the back side of the oil tank moves from back to front for salvage, and moves to the end. At this time, the movable side plate is located at the back side of the bottom plate, and the scoop net moves upward out of the oil tank, and the rotator drives the scoop net to rotate clockwise. Because the movable side plate is slidably mounted on the bottom plate, when the bottom plate rotates, the center of gravity of the movable side plate changes, and it will move from back to front, and while completing the reversal, the residue on the bottom plate will be discharged.

[0039] The utility model can realize automatic frying of bean curd skin, realize automated production, get rid of manual production, effectively improve production efficiency, and ensure frying quality. Specifically, the bean curd skin is placed on the feeding tray 31 manually or mechanically. Because the two groups of feeding mechanisms 3 are symmetrically arranged, only one worker or one device is needed between the two groups of feeding mechanisms 3 to place the bean curd skin on the feeding tray 31 during feeding. The feeding tray 31 is then driven by the feeding assembly to move to the skewers 41. The skewers 41 are just inserted into the feeding tray 31 from the inlet 314, and the bean curd skin is just located between the two skewers 41. Then, the skewers 41 are driven by the longitudinal assembly 43 to move downward from the outlet 315 to move out of the feeding tray 31. One end of the bean curd skin is folded in half and moved downward to the oil pan under the drive of the skewers 41 to start frying.

Specifically, one end of the bean curd skin is folded in half and fixed between two skewers 41 to ensure that the skewers 41 can drive the bean curd skin to move. When rolling, the skewers 41 first move toward the de-oiling plate 51 to clamp the bean curd skin between the skewers 41 and the de-oiling plate 51, and then, the bean curd skin is moved horizontally. The forward component 44 cooperates with the longitudinal component 43 to drive the skewer 41 to move upward along the de-oiling plate 51, and spread the bean skin on the de-oiling plate 51. Because the bean skin is fixed on the skewer 41 by being folded in half, the skewer 41 does not have a clamping force on the bean skin. Therefore, in order to prevent the bean skin from being separated from the skewer 41 when the skewer 41 drives the bean skin to move upward, the de-oiling plate 51 is used to receive the bean skin to prevent the bean skin from being separated from the skewer 41, and the oil on the bean skin can flow back to the oil pan along the de-oiling plate 51. Then, the rotating component 42 drives the skewer 41 rotates, and because one end of the bean skin is fixed on the skewer 41, the rotation of the skewer 41 will drive the bean skin to roll, thereby completing the rolling of the bell roll, and because the skewer 41 is in contact with the deoiling plate 51, the skewer 41 will also generate an extrusion force on the bean skin during the process of rolling the bean skin, squeezing out the oil in the bean skin, thereby ensuring the efficient oil-free production of the bell roll. In addition, the utility model can ensure that the bell roll is well kept in a rolled state before it is completely cooled, thereby ensuring that the produced bell roll is of good quality and consistent appearance. Specifically, The bean curd skin is processed into a bell roll immediately after frying, and the bell roll is made before the bean curd skin is cooled, and then sent between the two opened cylinder sheets. When it is transported to the right place, the finger cylinder controls the two cylinder sheets to close, and fixes the bell roll between the two cylinder sheets. The circular cavity formed by the two cylinder sheets can well keep the bell roll in a rolled state, so as to ensure that the bean curd skin can be kept in a rolled state after cooling, thereby providing a bell roll with excellent appearance. Then, the third driver drives the two cylinder sheets to move out, and the finger cylinder controls the two cylinder sheets to open, and the bell roll is transported out;

[0041] The utility model also provides a structure for salvaging residues and unqualified bell rolls. Since the skewers 41 do not have a clamping force on the bean curd, the bean curd may fall during the frying process. In order to salvage the fallen bean curd in time and avoid over-frying, the utility model provides a sensor at the de-oiling plate 51 to sense whether there is bean curd on the skewers 41 that move there. If the bean curd falls, the sensor cannot detect the bean curd and transmits a signal to the controller. The controller controls the scooping net assembly to salvage the fallen bean curd, and the scooping net 23 here can be automatically dumped. Specifically, in the initial state, the scooping net 23 is located at the front side of the oil tank 21. When the scooping net 23 moves from front to back for salvaging, it moves to the end. At this time, the movable side plate 232 is located at the front side of the bottom plate 231, and the scooping net 23 moves upward out of the oil tank 21. The rotator drives the scoop net 23 to rotate counterclockwise. Since the movable side plate 232 is slidably mounted on the bottom plate 231, when the bottom plate 231 rotates, the movable side plate 232 will move from front to back. While completing the reversal, the residue on the bottom plate 231 will be discharged, thereby completing the salvage. When the sensor cannot detect the bean curd skin again, at this time, the scoop net 23 located at the rear side of the oil tank 21 moves from back to front for salvage. When it moves to the end, the movable side plate 232 is located at the rear side of the bottom plate 231, and the scoop net 23 moves upward out of the oil tank 21. The rotator drives the scoop net 23 to rotate clockwise. Since the movable side plate 232 is slidably mounted on the bottom plate 231, when the bottom plate 231 rotates, the center of gravity of the movable side plate 232 changes, and it will move from back to front. While completing the reversal, the residue on the bottom plate 231 will be discharged.
