When the distance between the two transferring and conveying components is required to be adjusted, the corresponding transferring and conveying components are dragged through the locking bolts 17 and then locked.
In order to transfer and cut off the ends of the two pulled-apart strip-shaped dough-dividing blocks, in the embodiment, a cutting and transferring device 5 capable of synchronously cutting off the front ends of the two strip-shaped dough-dividing blocks to form two dough-dividing blocks and transferring the dough-dividing blocks is arranged on the outer sides of the two transferring and conveying devices 4;

after the ends of the two strip-shaped dough dividing blocks move to the corresponding side weighing and transferring device 6, the two strip-shaped dough dividing blocks are transversely cut by the cutting knife 18 respectively after the set time or weight is reached, so that two independent dough dividing blocks are formed, and the dough dividing blocks are continuously transferred to the corresponding secondary weighing and transferring device 6 to carry out secondary weighing, so that the purpose of accurate weighing is achieved.
In particular, in the present embodiment, the primary weighing and transferring device 6 and the secondary weighing and transferring device 7 are each constituted by a weighing device and a micro conveyor (the micro conveyor has a structure similar to that of the main conveyor 1) fixedly mounted on top of the weighing device (the weighing device is a common weight sensor fixedly mounted on an outer frame to form a stable structure).

The adjusting mode is simple, and when the deviation device 2 drives the main conveying belt 1 to deviate integrally, the defect of belt deviation caused by end part adjustment can be effectively avoided.
In particular, in this embodiment, in order to achieve more accurate weight balance of the feedback-adjusted dough, a dough pressing roller 8 for pressing the long dough piece directly below the output end of the main conveyor 1 is further provided directly above the output end of the main conveyor 1.
