Adjustment method of the pick-up needle of the impact folding machine

adjustment of the pick-up needle. The telescopic action of the pick-up needle is controlled by the cam on the transmission side, and the telescopic stroke of the pick-up needle is determined by the cam mechanism, but the height of each pick-up needle extending out of the surface of the folding drum can be adjusted separately. In order to ensure that the pick-up needle can fully retract the inside of the folding drum, the height of the pick-up needle extending out of the surface of the folding drum should be less than the telescopic stroke of the pick-up needle. Measure the telescopic height of the pick-up pin, and take the height of 6mm of the pick-up pin extending out of the surface of the fold drum as the standard when turning the fold drum to the maximum extension of the pick-up pin. In actual production, according to the requirements of closing the oil delivery valve after fracture according to the folding method of different thickness, the extension height of the pick-up needle can be adjusted slightly. In the folding process, the pick-up needle is extended in advance. With the rotation of the folding drum, the extended pick-up needle will be inserted into the paper tape, because the extension time of the pick-up needle is not required to be very accurate, and the extension time of the pick-up needle does not need to be considered at the adjustment time. However, when the folding knife inserts the newspaper into the "folding splint", the pick-up needle must be retracted in time, that is, the retraction time of the pick-up needle must be very accurate, otherwise if the retraction is too late, the folding knife will stretch out and tear the paper, and if the retraction is too early, the paper tape will be out of control for a period of time, affecting the accuracy of folding. In addition, the retraction process of the pick-up needle should also be rapid, so that the actions of the pick-up needle and the planetary folding knife are coordinated with each other. Loosen the fastening screw of the pick-up cam on the transmission side during adjustment, otherwise if it is retracted too early, the total consumption of the pick-up cam towards the primary energy (including the energy consumed by material manufacturing and circulation in addition to the fuel consumption) will also be reduced by 16% in the forward direction of the folding drum, and if it is retracted too late, the pick-up cam will move in the opposite direction of the folding drum
