Cotton thread spring forming equipment

Abstract

The invention discloses cotton thread spring forming equipment. The cotton thread spring forming equipment comprises a thread feeding mechanism, a wire feeding mechanism, a winding mechanism, a carrying mechanism, a cropping mechanism and a carrier assembly. The winding mechanism comprises a winding bottom plate, a screw pitch module, a vertical plate, a large gear, a winding drive gear and a winding sleeve, and the screw pitch module can drive the vertical plate to move front and back. The center of the vertical plate is provided with a main shaft through a bearing in an erected manner, wherein the main shaft can rotate relative to the vertical plate, and the large gear is fixed to the main shaft and is in meshing connection with the winding drive gear. A through hole is formed in the center of the main shaft. A cotton thread conveying rod of the thread feeding mechanism penetrates out of the through hole of the main shaft, and the winding sleeve fixedly sleeves the outer end of the cotton thread conveying rod. The cotton thread spring forming equipment is high in machining precision, screw pitch adjustment is convenient, lubricating oil filling is not needed, the spiral inner diameter of a metal wire can be smaller than the outer diameter of a cotton thread in a free state, tight attachment of the metal wire and the cotton thread is achieved, and accordingly accurate controlover the effective resistance value and the heating effect of a resistance wire is achieved.

Description

technical field [0001] The invention belongs to the technical field of automatic processing equipment, and in particular relates to a cotton thread spring forming equipment. Background technique [0002] When the core component of the electronic cigarette device is processed, the resistance wire needs to be spirally formed on the cotton thread. When using the traditional spring machine to process the core part, due to the limitation of the forming principle, it is not only necessary to add lubricating oil to cause pollution of the resistance wire, but also the forming inner diameter of the resistance wire needs to be larger than the outer diameter of the cotton thread, otherwise cotton thread and metal wire will be produced intertwined. However, if the forming inner diameter of the resistance wire is larger than the outer diameter of the cotton thread, the resistance wire may move along the axis of the cotton thread, and the heating effect of the resistance wire will also b...

When using the traditional spring machine to process the core part, due to the limitation of the forming principle, it is not only necessary to add lubricating oil to cause pollution of the resistance wire, but also the forming inner diameter of the resistance wire needs to be larger than the outer diameter of the cotton thread, otherwise cotton thread and metal wire will be produced intertwined

However, if the forming inner diameter of the resistance wire is larger than the outer diameter of the cotton thread, the resistance wire may move along the axis of the cotton thread, and it will also affect the heating effect of the resistance wire.
