Problems solved by technology
[0002] At present, the folding mechanism of the slot insulation forming insertion machine basically does not have a pre-creasing device. The insulating paper enters the folding block through the guide block and is directly folded. The disadvantage is: because there is no pre-creasing, the insulating paper directly passes through the folding The block is folded 180°, the resistance is too large, it is easy to damage the insulating paper and cause the size of the hem to be unstable

The invention relates to electrical mechanical processing equipment, and particularly discloses a pre-creasing device for an insulation paper edge-folding mechanism on a slot insulation forming insertion machine. The pre-creasing device is characterized in that the right end of a guide block is provided with an edge-folding block, the left side of the edge-folding block is provided with an upper compression roller shaft, one end of the upper compression roller shaft is connected with the edge-folding block through a connecting plate, the other end of the upper compression roller shaft is provided with an upper compression roller with a triangular tip projection, the bottom of a base plate below the upper compression roller is provided with a lower compression roller shaft support, a lower compression roller shaft is installed in a central hole of the lower compression roller shaft support, and a lower compression roller with a V-shaped groove is arranged on the lower compression roller shaft. The pre-creasing device has the advantages that creases are made before edge-folding, the resistance for edge-folding is reduced, and edge-folding is stable.
Description
technical field [0001] The invention belongs to electrical machinery processing equipment, in particular to a pre-indentation device for a hemming mechanism on a groove insulation forming and inserting machine. Background technique [0002] At present, the folding mechanism of the slot insulation forming insertion machine basically does not have a pre-creasing device. The insulating paper enters the folding block through the guide block and is directly folded. The disadvantage is: because there is no pre-creasing, the insulating paper directly passes through the folding The block is turned over 180°, the resistance is too large, it is easy to damage the insulating paper and cause the size of the hem to be unstable. Contents of the invention [0003] The purpose of the present invention is to provide a pre-creasing device which reduces the resistance and injury probability of insulating paper folding and stabilizes the folding. [0004] The technical solution of the presen...
