Description
Technical Field
The utility model relates to an automatic twist screw device.
Background
At present, the slit extrusion type coating die head mainly realizes the slit gap adjustment process through three modes of bolt adjustment, micrometer adjustment or stepping motor adjustment. Micrometer adjustment or step motor adjustment utilizes rigid coupling with the differential head with adjust fast rigid connection, adjusts control slit clearance through adjusting the differential head.
The mode that the bolt is used for adjusting and controlling the slit gap means that the bolt is used for screwing down to apply acting force to the upper die lip or the lower die lip, the upper die lip or the lower die lip deforms, and the slit gap between the upper die and the lower die changes. The bolt adjusting mode has obvious effect at the initial stage of equipment use, but the adjustment is difficult due to lip deformation failure after the equipment is used for a period of time. In addition, due to the defects of abrasion, deformation, clamping stagnation and the like of the thread of the bolt, the quick adjustment of the coating process cannot be realized, and the gap of the slit cannot be accurately controlled; and the bolt adjusting process is seriously dependent on the experience of operators, and the adjustment has hysteresis.
The mode that the slit clearance is adjusted and controlled to the micrometer means that a structure similar to a micrometer is utilized, an extension rod of the micrometer is connected with a connecting rod through a coupler, the connecting rod is connected with an adjusting sheet, the adjusting sheet is controlled to ascend or descend by screwing a micrometer differential head by an operator, and the slit clearance between an upper die and a lower die is changed. The micrometer is adjusted to have scale value display, and the slit gap adjusting and controlling precision is high; the adjustment process also depends on the experience of operators, and the adjustment has hysteresis; because each micrometer structure is independently connected with one adjusting sheet, the height difference exists between the adjusting sheets, and the quality problems of stripes, dark marks and the like occur in the coating process; there is a risk of failure of the areal density control.
All need manual operation above the mode of regulation, and the manual bolt of twisting or twist the micrometer and adjust equipment, this process needs to spend a large amount of manpowers and time to operate.
