Technical Field
The utility model relates to an enameled round wire rolls off production line make-up machine technical field, in particular to enameled round wire rolls off production line make-up machine's automatic pay-off.
Background
At present, the conventional enameled round wire inserting forming machine in China only utilizes a wire feeding pressing cylinder and a wire pressing device to directly pull an enameled round wire coil arranged on a pay-off rack under the drive of a servo motor to finish the wire feeding action. During the wire feeding process, the friction force of the motor dragging and compressing needs to overcome the factors such as the weight of a wire coil and the friction force of a pay-off rack, and the armature coil after the wire is off-line molded requires that the length error of the inner pin and the outer pin of the wire body is within 0.5mm and the wire body is continuous, stable and consistent.
In a conventional offline forming machine, the enameled round wire is in pressing contact with a lower cambered surface and a top surface, and the pressing friction force is limited. In addition, in order to reduce the waste at the head end and the tail end of the wire coil, 60KG weight is adopted for wire coil loading; a rotating shaft of a wire coil arranged on the pay-off rack and a support of the pay-off rack adopt direct cambered surface contact to increase friction force so as to prevent the wire coil from loosening and being separated from the wire coil caused by too many rotation turns of the wire coil in the wire feeding process. The drum generally adopts the cask, and the drum spoke center is very difficult very accurate with shaft hole center processing concentricity, causes the drum to appear the swing back-draw phenomenon before the rotation stops easily when eccentric great. To sum up, when the conventional enameled round wire inserting molding machine works in a full load of a 60KG wire loading disc, the inserting molded product is easy to be damaged due to unstable wire feeding length, material scrapping and shutdown production reduction.

The adjusting screw 702 is vertically mounted on the bracket 3, and the end of the adjusting bracket 701 rides over the adjusting nut 703. When the adjusting nut 703 rotates upward, the adjusting bracket 701 drives the friction wheel 5 to swing toward the direction close to the wire spool 4, and adjusts the pressure between the friction wheel 5 and the wire spool 4, so that the enameled round wire can generate a proper friction force with the wire spool 4 when passing through the space between the friction wheel 5 and the wire spool 4.
