Segmental calendering device for flexible flat cable

A segmental calendering device for a flexible flat cable, comprising:

• a framework, including:
• a left wallboard, with a left rolling chamber formed in the left wallboard;
• a right wallboard, with the right wallboard disposed opposite to the left wallboard, a right rolling chamber, corresponding to the left rolling chamber, formed in the right wallboard, the right rolling chamber having the same shape and size as the left rolling chamber;
• a supporting bar connected between the left wallboard and the right wallboard;
• and
• a frame roof, with a left end of the frame roof fixed to a top of the left wallboard, a right end of the frame roof fixed to a top of the right wallboard;
• a pair of left-rolling sliding guide mechanisms fixed opposite to each other within the left rolling chamber;
• a pair of right-rolling sliding guide mechanisms fixed opposite to each other within the right rolling chamber;
• an upper-calendering roller and a supporting mechanism of the upper-calendering roller, with the upper-calendering roller rotatably supported within the supporting mechanism of the upper-calendering roller and disposed above a position between the left wallboard and the right wallboard, the supporting mechanism of the upper-calendering roller sliding along the pair of left-rolling sliding guide mechanisms and the pair of right-rolling sliding guide mechanisms;
• a lower-calendering roller disposed below the upper-calendering roller correspondingly and rotatably supported between the left wallboard and the right wallboard;
• a pressing mechanism for applying a pressure on the supporting mechanism of the upper-calendering roller and for adjusting the pressure, with the pressing mechanism disposed on the frame roof and connected to the supporting mechanism of the upper-calendering roller;
• and
• a space-controlling pole of the flexible flat cable, including:
• a mandrel;
• at least one positioning wheel fixed to the mandrel;
• a rod group;
• a left-control block slidably disposed on the mandrel;
• a right-control block slidably disposed on the mandrel;
• a left-pin wheel group configured to slide along the mandrel disposed on a left side of the positioning wheel;
• and
• a right-pin wheel group configured to slide along the mandrel disposed on a right side of the positioning wheel;
• wherein the left-pin wheel group and the right-pin wheel group are constructed as a set of wheel groups, each of two sides of the set of wheel groups is disposed with a fixing wheel fixed to the mandrel, the rod group comprises a left merging rod, a left separating rod, a right merging rod and a right separating rod, the left merging rod is connected to a first pin wheel of a left-side of the left-pin wheel group, the right merging rod is connected to a first pin wheel of a right-side pin wheel of the right-pin wheel group, the left separating rod toggles from a second pin wheel of the left-side of the left-pin wheel group to a pin wheel of a right-side of the left-pin wheel group when shifting left, the right separating rod toggles from a second pin wheel of the right-side of the right-pin wheel group to a pin wheel of a left-side of the right-pin wheel group when shifting right, the left-control block is connected to the left merging rod and the left separating rod, and the right-control block is connected to the right merging rod and the right separating rod.
