Specifically, the middle chain plate feeding unit comprises a first charging barrel 52 arranged along the vertical direction, and an opening for the first push plate 51 to pass through is formed in the lower end of the first charging barrel 52. When the seed chain plate is in operation, the middle chain plate is manually placed into the first material placing barrel 52, and the seed chain plate automatically falls into the front end of the first push plate 51 under the action of gravity.
Further, as shown in fig. 9, the first push plate 51 is further provided with a material receiving channel 511 disposed along a length direction, and the material receiving channel 511 penetrates through the first push plate 51 along a vertical direction. The middle chain plate conveying module 5 further comprises a receiving component 8, the receiving component 8 comprises a receiving cylinder 81 and a plug 82, and the plug 82 is positioned below the middle chain plate feeding unit and aligned with the receiving channel 511. The material receiving cylinder 81 drives the top 82 to move up and down.

Because the middle chain plate conveying module 5 is opposite to the dislocation assembly from side to side, the middle chain plate just enters the profiling groove of the dislocation assembly after being pushed into the middle chain plate feeding station 121.
After the middle chain plate 01 enters the imitation groove, the transverse driving unit 32 drives the first dislocation slide block 33 to move relative to the second dislocation slide block 34, at the moment, the second dislocation slide block 34 is still in a static state in contact with the limiting unit 35 under the elastic force of the elastic piece 37, and in the process, the first clamping plate and the second clamping plate are gradually dislocated, and the middle chain plate is synchronously driven to complete dislocation.
During the movement of the first dislocating slider 33 relative to the second dislocating slider 34, the elastic element 37 gradually resets until it is transformed from a compressed state to an extended state. When the elastic member 37 extends to a certain extent, the elastic force of the elastic member 37 drives the second dislocating slider 34 to start to move synchronously with the first dislocating slider 33, and at this time, the dislocating process of the middle chain plate is completed.
