A screw centering mechanism

Abstract

The invention discloses a screw rod alignment mechanism which comprises a left alignment unit, a right alignment unit and an alignment motor, wherein the left and right alignment units are driven by the alignment motor to drive a screw rod; the left and right sides of the screw rod are correspondingly connected with a left section thread and a right section thread; the left section thread is connected with the left alignment unit through a left nut structure; the right section thread is connected with the right alignment unit through a right nut structure; walking tracks are arranged on two sides parallel to the screw rod; a left pulley rod and a right pulley rod are correspondingly arranged at the middle parts of the left and right alignment units; and a left alignment end and a right alignment rod are correspondingly arranged at the end parts of the left and right pulley rods. The screw rod alignment mechanism is high in automation degree, can realize multilayer free alignment, and is higher in working efficiency and higher in practicability.

Description

technical field [0001] The invention relates to the technical field of construction machinery application, in particular to a screw rod centering mechanism. Background technique [0002] In the packaging and processing process of the automatic production line of non-woven fabrics, a very precise position is required to ensure the quality requirements of packaging and processing, so a centering mechanism is required to ensure the accurate position of materials and products. At present, simple equipment and manual operation are still used in many domestic production lines, which are labor-intensive and production efficiency is too low; the existing centering devices on the market generally use more complicated connecting rod mechanisms, or are realized by cylinders and chain structures. The effect of synchronous centering, the cost is relatively high, and the structure is relatively complicated, which is not suitable for economical and effective technological development; at t...

Problems solved by technology

At present, simple equipment and manual operation are still used in many domestic production lines, which are labor-intensive and production efficiency is too low; the existing centering devices on the market generally use more complicated connecting rod mechanisms, or are realized by cylinders and chain structures. The effect of synchronous centering, the cost is relatively high, and the structure is relatively complicated, which is not suitable for economical and effective technological development; at the same time, multi-layer non-woven fabric products are usually stacked by multiple cylindrical small cloth rolls, which require a reasonable design of the centering bracket To ensure that the small cloth rolls do not move relative to each other during the centering process
