Description

Technical Field

[0001] The utility model relates to the technical field of bean curd roll production equipment, and in particular to a mechanism for removing unqualified ring rolls. Background Art

[0002] The Chinese invention patent with patent number CN114766524 B discloses a fried bean curd roll production line, which adopts a clamping rod to clamp the bean curd, and realizes the function of clamping the bean curd by forming a gap between two clamping rods for the bean curd to be inserted. In order to ensure that the clamping position of the bean curd can be fully fried, the gap between the two clamping rods is greater than the thickness of the bean curd, so this structure does not have a clamping force on the bean curd, which also leads to the situation that the bean curd falls off from the clamping rod and the bean curd moves backward during the frying process. Once the bean curd falls into the oil pan, excessive frying will cause the bean curd to be burnt black. If the bean curd moves backward, the clamping rod cannot effectively roll up the bean curd or does not roll up all the bean curd. When the clamping rod puts the bean curd between the first arc-shaped piece and the second arc-shaped piece, part of the bean curd will be exposed outside the first arc-shaped piece and the second arc-shaped piece. If the unqualified bean curd roll is not removed in time, the unqualified bean curd roll will be mixed with the qualified bean curd roll, which will affect the subsequent production of bean curd rolls.

[0023] The utility model can effectively remove unqualified bean curd rolls, because the clamping rod 2' does not have a clamping force on the bean curd, and the bean curd may fall during the frying process. In order to timely pick up the fallen bean curd and avoid over-frying, the utility model sets a first sensor 7 at the de-oiling plate 5' to sense whether there is bean curd on the clamping rod 2' moving there. If the bean curd falls, the first sensor 7 cannot detect the bean curd and transmits a signal to the controller. The controller controls the scooping net 2 to work and pick up the fallen bean curd. In addition, the scooping net 2 can be automatically dumped. Specifically, in the initial state, the scooping net 2 is located at the front side of the oil pan 1'. , when the scoop net 2 moves from front to back for salvage, it moves to the end. At this time, the movable side plate 22 is located at the front side of the bottom plate 21, and the scoop net 2 moves upward out of the oil pan 1'.

While completing the reversal, the residue on the bottom plate 21 will be discharged, thereby completing the salvage. When the sensor cannot detect the bean curd skin again, at this time, the scoop net 2 located at the rear side of the oil pan 1' moves from back to front for salvage, and moves to the end. At this time, the movable side plate 22 is located at the rear side of the bottom plate 21. The scoop net 2 moves upward out of the oil pan 1', and the rotator 3 drives the scoop net 2 to rotate clockwise. Because the movable side plate 22 is slidably mounted on the bottom plate 21, when the bottom plate 21 rotates, the center of gravity of the movable side plate 22 changes, and it will move from back to front. While completing the reversal, the residue on the bottom plate 21 will be discharged. This is the front-end rejection process of unqualified bean curd rolls. If the bean curd does not fall into the oil pan 1', but the position of the bean curd is offset, or the position of the bean curd changes when the clamping rod 2' leaves the oil pan 1', that is, one end of the bean curd is not effectively fixed on the clamping rod 2', resulting in the clamping rod 2' failing to effectively drive the bean curd to roll or not rolling it completely when rotating. In order to remove the bean curd resulting from this situation, the utility model is further provided with a second sensor 9. Since the clamping rod 2' cannot drive the bean curd to be rolled or is not completely rolled up when rotating, when the clamping rod 2' puts the bean curd into the first arc-shaped piece 6' and the second arc-shaped piece 7', part of the bean curd will be exposed under the first arc-shaped piece 6' and the second arc-shaped piece 7'. At this time, the second sensor 9 located under the first arc-shaped piece 6' and the second arc-shaped piece 7' will sense the existence of the bean curd, and through the controller, control the second driver 8' to output the unqualified bean curd roll to the waste basket 1, thereby completing the subsequent unqualified bean curd roll removal process.
