The main process steps of the belt layer feeding rack are as follows:

1) The 1# belt layer is guided from the feeding trolley 7 below the 1# conveying template 51 through the guide device 8 to form a storage pocket 13. The detection switch above the storage pocket 13 detects its up and down position and feeds back the signal to Decoupling device 8, to control its decoupling speed.

2) The 1# belt layer passes through the centering device 9 set at the rear end of the 1# conveying template 51 for pre-planning, and then conveys forward on the 1# conveying template 51. When it is conveyed to the front-end correcting device 11, it starts to correct the deviation .

3) The cylinder 23 connected to the 1# laminating template 41 is in a shrinking state at this time, so that the 1# laminating template 41 is on the plane where the 1# conveying template 51 is located. At this time, the 1# belt layer continues to be transported to the 1# fit on template 41. When the optical switch in the length measuring device 12 on the 1# laminating template 41 detects the 1# belt layer, the PLC starts counting and measures the length of the 1# belt layer passed through. When the length reaches the preset value, the 1# conveying mold 51 plate and the 1# bonding template 41 stop conveying, and the cutting device 10 implements cutting.

4) After the cutting is completed, the 1# conveying template 51 and the 1# laminating template 41 continue to convey the 1# belt layer, and at the same time, the PLC counts and measures, and measures the length of the belt layer for the second time. When the 1# belt layer moves in place, stop conveying, complete material preparation, and wait for lamination. At the same time, 2#, 3#, 4# belt layers have also completed material preparation and are waiting for bonding.
