Flexible material moving device and method, and sewing device

Abstract

The invention provides flexible material moving device and method, and a sewing device. The moving device comprises a hollow device main body, an elastic part, a ranging sensor and an air pump controller; a steel needle fixing seat is movably arranged in the hollow device main body; a plurality of steel needles are convexly arranged on the lower surface of the steel needle fixing seat and pass through the bottom of the hollow device main body for inserting a flexible material; the upper surface of the steel needle fixing seat and the hollow device main body encircle a closed air pressure chamber which provides driving force for needling; the air pressure chamber is connected with an air pump through an air pipe; the elastic part is arranged in a clearance between the lower surface of the steel needle fixing seat and the hollow device main body and is extruded by the steel needle fixing seat to deform to provide elasticity for the steel needle fixing seat; the ranging sensor is arranged in the air pressure chamber and faces the upper surface of the steel needle fixing seat to measure the spacing between the steel needle fixing seat and the ranging sensor; the air pump controller is connected with the air pump to control the air pump so as to drive the steel needle fixing seat to move; the air pump controller is further electrically connected with the ranging sensor and drives the steel needle fixing seat to move until the spacing is equal to the preset threshold value. The moving device is accurate in controlling of the needling depth and is simple in structure.

Description

Technical field [0001] The invention relates to the field of sewing technology, in particular to a movement device, a movement method and a sewing device of flexible materials. Background technique [0002] At present, most sewing operations use vacuum suction to grasp the fabric. However, it is impossible to perform operations such as rotating the fabric when sewing the fabric on the operating table by this method, so operations such as needle piercing are required. [0003] However, there is no device in the prior art that can precisely control the thickness of the needle stick and has a simple structure, which greatly affects the quality of clothing, which is actually a technical problem to be solved in the industry. Summary of the invention [0004] In view of the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide a movement device, a movement method and a sewing device for flexible materials, and solve various defects in the prior ...
