Automatic air sweeping device of cloth paving machine

Abstract

The invention discloses an automatic air sweeping device of a cloth paving machine. An air sweeping rod assembly is located at the front end of a cutter assembly, the two ends of the air sweeping rodassembly are each connected with a swing rod arm, the swing rod arms are connected with the lower end of a steel wire rope, the upper end of the steel wire rope is connected with a cloth pressing shaft of the cutter assembly through a support, the cloth pressing shaft rotates in one direction to pave cloth, the cloth pressing shaft rotates to drive the steel wire rope to move, the lower end of thesteel wire rope enables the swing rod arms to do downward indexing motion due to the gravity of the air sweeping rod assembly, the air sweeping rod assembly is pressed on the surface of the cloth andslides, and air below the cloth is scraped and swept out; and the cloth pressing shaft rotates in the other direction to carry out cloth paving return stroke, the lower end of the steel wire rope isdriven to enable the swing rod arms to do upward lifting motion through a pulley assembly, and the air sweeping rod assembly leaves the surface of the cloth. The automatic air sweeping device has theadvantages that efficiency is high, the cloth paving quality is good, and the problems that due to the fact that air exists in airtight sealing cloth, wrinkles are generated, and displacement is generated due to secondary air sweeping are effectively solved.

Description

technical field [0001] The invention relates to the field of cloth spreading machines, in particular to an automatic wind sweeping device for cloth spreading machines. Background technique [0002] In the process of laying the fabric, the spreader adopts a multi-layer structure. Air will be generated between the upper fabric and the lower fabric, especially for airtight sealed fabrics. Fabric is difficult to lay neatly. At present, the sweeping device of the spreader is always pressed on the cloth, and the cloth is repeatedly scraped back and forth with the movement of the spreader, which can easily cause the cloth to move due to the repeated scraping of the sweeping device. , which in turn leads to misalignment of both ends of the spread, resulting in poor spread quality and low production efficiency. This is the problem that this application needs to focus on solving. Contents of the invention [0003] The technical problem to be solved by the present invention is to ...

[0002] In the process of laying the fabric, the spreader adopts a multi-layer structure. Air will be generated between the upper fabric and the lower fabric, especially for airtight sealed fabrics. Fabric is difficult to lay neatly

At present, the sweeping device of the spreader is always pressed on the cloth, and the cloth is repeatedly scraped back and forth with the movement of the spreader, which can easily lead to the movement of the cloth that has been laid flat due to the repeated scraping of the sweeping device. , which in turn leads to misalignment of both ends of the spread, resulting in poor spread quality and low production efficiency
