And the interval between the synchronous driving roller 321 and the synchronous driven roller 322 of the synchronous belt 32 is not less than the interval between the edge protection frames 21 at both sides to satisfy the movement and stop of the cutter 33.

Example 5

The embodiment of the application discloses cutting mechanism for steamed bun production.

Referring to fig. 1, in the present embodiment, in order to determine the position of the dough belt 41 while moving on the conveyor belt 22, opposed photoelectric switches are provided on both sides of the conveyor belt 22. When the opposed photoelectric switches are blocked, the dough strip 41 has moved to this position. One or more sets of correlation photoelectric switches can be arranged. In the present embodiment, a pair of opposed photoelectric switches, which may also be referred to as an on-off photoelectric switch 37, are provided downstream of the cutter frame 31 in the conveying direction of the conveyor belt 22, and the downstream position is a start position for activating the cutter 33. That is, the on-off photoelectric switch 37 is interlocked with the synchronous motor 324 of the synchronous belt 32, and the on-off photoelectric switch controls the start of the synchronous motor 324 after detecting the signal of the correlation photoelectric switch.

In the present embodiment, the on/off photoelectric switch 37 is interlocked with the conveying motor 224 of the conveyor belt 22, and can control the stop of the conveying motor 224. So that the conveyor belt 22 stops during cutting, and the cut dough pieces 42 are square to determine the total volume of the dough pieces 42. And the uniformity of the subsequent tablet press after the compression is more convenient. Of course, the conveyor belt 22 may not be stopped.

Preferably, in the present embodiment, a set of opposed photoelectric switches, which may also be referred to as tail-cut photoelectric switches 36, are provided at the cutting frame 31 and at the moving path of the cutting knife 33 for monitoring whether the dough strip 41 is present at the cutting knife 33.

The industrial control PLC system receives signals of the proximity switch 34 and the correlation photoelectric switch, sends out a control instruction and controls the conveying motor 224 and the synchronous motor 324 to move.

Specifically, in this embodiment, the dough output from the dough kneading device is primarily pressed to form the dough belt 41, and then enters the conveyer belt 22, and the conveyer motor 224 drives the conveyer belt 22 to rotate, so as to drive the dough belt 41 to convey forward. When the dough belt 41 passes through the tail-cutting photoelectric switch 36, the dough belt 41 is monitored to pass below the cutter 33, when the dough belt 41 passes through the start-cutting photoelectric switch 37, the dough belt 41 is monitored to pass through the start-cutting photoelectric switch 37, at the moment, the industrial control PLC system controls the conveying motor 224 to stop and the synchronous motor 324 to start, so that the dough belt 41 stops moving in the conveying direction of the conveying belt 22, and the cutter 33 moves from one side of the dough belt 41 to the other side, and the dough belt 41 is cut off to form the dough 42. After the cutting is completed, the dough pieces 42 can be transported to the sheeter of the next process by activating the transport motor 224 via the conveyor belt 22. And when the dough 42 completely falls into the tablet press, the conveying motor 224 is stopped, and a tail correlation photoelectric switch can be arranged at the tail of the conveying belt 22 to detect whether the dough completely falls or not. The conveying motor 224 is started again to be connected with the processes of the tablet press, the tablet press finishes the dough pressing and conveys the pressed dough pieces to the next process, and the dough blocks 42 are stopped on the conveying belt 22 after being cut to wait for the subsequent action. After the sheeter is automatically or manually discharged, the system signals the conveyor motor 224 of the conveyor belt 22 to move the conveyor belt 22 to feed the cut dough pieces 42 into the sheeter. Since it is not related to the structure of the present embodiment, it will not be described in detail here. After the conveying motor 224 is started again, the dough cutting block 42 is circulated, and the difference is only that the moving direction of the cutting knife 33 is opposite. When the length of the dough belt 41 is short, the dough belt 41 firstly reaches the end-cutting photoelectric switch 36, then the dough belt is continuously conveyed to the start-cutting photoelectric switch 37, at the moment, the tail part of the dough belt 41 passes through the end-cutting photoelectric switch 36, the end-cutting photoelectric switch 36 is not shielded, the dough cutting block 42 is not operated, and the situation that the small dough cannot be sent out after entering the continuous tabletting machine can be avoided.

In an embodiment of the present invention, a power switch is provided on a control box of the industrial PLC system to control power supply everywhere, and a start button, a stop button, an automatic button, a manual button, and the like are provided. Automatic and manual buttons may select the mode of operation of the device. When the automatic mode is selected, the equipment in the process is linked with the equipment in the next process, and the dough belt 41 automatically and sequentially feeds the flour blocks 42 into the tablet press in the next process through the conveying belt 22 after being cut. When the conveyer belt 22 is working normally, the cutter 33 stops at the proximity switches 34 at both sides of the conveyer belt 22. And a buzzer alarm is set, when the cutter 33 is not stopped at the proximity switches 34 at the two sides of the conveyer belt 22, the alarm is sent out, and the conveyer belt 22 can not be allowed to move.
