Description

Technical Field

[0001] The utility model relates to the technical field of fabric positioning, in particular to a jacquard fabric positioning device. Background Art

[0002] The jacquard fabric positioning device requires the use of a fixture to fix and position the fabric. It is usually used in the processing and cutting process to ensure that the fabric maintains the correct position and shape during the processing. Positioning auxiliary tools such as marking pens, rulers, templates, etc. are used to mark or assist in positioning on the fabric to help operators process and cut more accurately.

[0003] The existing patent (publication number: CN214114385U) proposes a fabric positioning device, which can effectively position the fabric. By adjusting the position of the adjusting roller, it can position fabrics of different materials or stretch degrees. It adopts a variety of positioning methods to facilitate the cutting of the fabric. At the same time, an auxiliary positioning component is added to make the fabric more stable and smooth during the positioning process, so that the cut fabric is very close to the expected specifications.

[0004] The above-mentioned fabric positioning device includes a workbench, a positioning roller A, a positioning roller B, an adjusting roller, a positioning roller C and a positioning roller D. The middle part of the workbench is provided with an empty groove inclined upward; a sliding mechanism is provided at the connection between the adjusting roller and the empty groove, and two groups of auxiliary positioning mechanisms are symmetrically provided on both sides of the sliding mechanism with the central axis of the sliding mechanism as the axis; the sliding mechanism includes a coupling, a screw, a screw slider and a rotating handle; the auxiliary positioning mechanism includes a rotating shaft A, a rotating shaft B, a buffer assembly and an auxiliary positioning assembly. The existing fabric positioning device is usually unable to position fabrics of different shapes and sizes. When the fabric is smaller than the positioning device, the fabric cannot be positioned. When the fabric is of an irregular shape, the positioning device can only partially position the fabric, so that the operator cannot perform the next step of the fabric operation. During the processing and cutting process, it is impossible to ensure that the fabric maintains the correct position and shape during the processing. Therefore, the utility model proposes a jacquard fabric positioning device to solve the above problems. Utility Model Content
