Description

Technical Field

[0001] The present invention relates to the technical field of clothing production, and particularly relates to a sewing mold applicable to inner lining cloth and a method for sewing inner lining cloth using the sewing mold for inner lining cloth. Background Art

[0002] Currently, in the clothing and textile industry, during the process of inner lining cloth operation, the traditional method is to use a single-needle machine for manual operation. Workers hold the inner lining cloth piece and the cup body for sewing operation, and require the overall flatness of the product to be relatively high and the turned edge at the edge to be within 2 mm. The operation difficulty for workers is large, the work efficiency is relatively low, and the quality cannot be guaranteed. Summary of the Invention

[0003] In view of this, in order to overcome the defects of the prior art, the purpose of the present invention is to provide a sewing mold for inner lining cloth. Using this mold for sewing inner lining cloth has good effects, the sewn product is flat and fitting, and the sewing thread is very close to the edge of the inner lining cloth piece.

[0004] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0005] A sewing mold for inner lining cloth includes a first template and a second template for clamping the inner lining cloth piece. A first sewing groove penetrating through the thickness direction is formed on the first template, and a second sewing groove penetrating through the thickness direction is formed on the second template. The first sewing groove and the second sewing groove have the same shape. A limiting line for limiting the sewing position of the sewing needle is arranged in the first sewing groove and / or the second sewing groove, and a blocking strip for blocking the edge of the inner lining cloth piece is arranged on the first sewing groove and / or the second sewing groove.

[0006] The inner lining cloth piece is clamped by the first template and the second template, and sewing grooves corresponding to the sewing paths are formed on the templates. A limiting line for limiting the sewing operation of the sewing needle is arranged in the sewing grooves, so that the position of the sewing needle during insertion is more concentrated and does not swing, making the product flat and fitting, and the sewing thread is very close to the edge of the inner lining cloth piece, and the product quality is controllable.

[0007] Preferably, the opening shapes of the first sewing groove and the second sewing groove match the preset sewing paths. The preset sewing paths are set according to the styles of the products.

[0008] Preferably, the limiting line is perpendicular to the extending direction of the first sewing groove and the second sewing groove, that is, the limiting line is parallel to the width direction of the sewing groove and perpendicular to the width direction of the sewing groove. The width of the sewing groove is greater than the width of the preset sewing thread.

[0009] Preferably, the limiting lines are evenly distributed at equal intervals in the first sewing groove and / or the second sewing groove.

[0010] More preferably, the distance between adjacent limiting lines is 0.1 - 1 mm.

[0011] Preferably, one end of the limiting line is fixed to the edge of the first sewing groove or the second sewing groove, and the other end of the limiting line is a free end. If limiting lines are provided in both the first sewing groove and the second sewing groove, the limiting lines in the two sewing grooves correspond one by one and are overlapped to better limit the sewing needle. In some embodiments, the limiting line is horsehair interlining, which is cheap and easy to obtain, and has a good limiting effect, ensuring that the sewing needle always operates within the sewing groove during sewing and does not touch the edge of the sewing groove.

[0012] The horsehair interlining in the present invention is a semi-finished fabric, similar to the form of false eyelashes in shape, and has multiple freely movable fibers at its end. When it is attached to the template corresponding to the sewing groove, it can limit the movement of the sewing needle.

[0013] Preferably, the number of the blocking strips is greater than or equal to the number of the lining pieces. The position of the blocking strip matches the edge of the lining piece. For example, if there are 3 lining pieces, 3 blocking strips are provided on the sewing die corresponding to the 3 lining pieces to achieve the function of blocking each lining piece. The blocking strip is a sponge strip.

[0014] More preferably, the distance between the sewing groove and the nearest blocking strip is 1 - 2.2 mm to ensure that the sewing thread of the sewn product is less than or equal to 2 mm away from the edge of the lining piece.

[0015] Preferably, the first template and the second template are further provided with pressing blocks for pressing the lining pieces, and the pressing blocks and the blocking strips are respectively located on both sides of the sewing groove.

[0016] In some embodiments, the first template and the second template are provided with a rotating mechanism for rotatably connecting the first template and the second template. The rotating mechanism is a hinge or a hinge, which facilitates opening and fitting the first template and the second template.

[0017] Corresponding positioning holes for cooperating with the workbench on the sewing equipment are provided on the first template and the second template to control the consistent position of the sewing die during sewing, making the quality of the product more uniform and controllable.

[0018] The present invention also provides a method for sewing the circular lining using the above circular lining sewing die, including the following steps:

[0019] 1) Design: Design the style of the lining and preset the sewing path and the width of the sewing line;

[0020] 2) Prepare materials: Prepare the lining pieces according to the lining style designed in step 1);

[0021] 3) Feeding: Place the lining piece corresponding in the circular lining sewing die, with the edge of the lining piece corresponding to the blocking strip. Then rotate and fit the first template and the second template so that the lining piece is located between the first template and the second template, and the pressing block presses the lining piece.

[0022] 4) Sewing: Place the circular lining sewing die with the clamped lining piece on the sewing equipment. During sewing, the sewing needle of the sewing equipment sews in the sewing groove.

[0023] Due to the adoption of the above technical solution, compared with the prior art, the beneficial effects of the present invention are as follows: The circular lining sewing die of the present invention clamps the lining piece through the first template and the second template, and a sewing groove corresponding to the sewing path is opened on the template. A limiting line for limiting the sewing operation of the sewing needle is arranged in the sewing groove, so that the position of the sewing needle during insertion is more concentrated and there is no swing. It can not only speed up the sewing speed of employees and improve production efficiency, but also the sewing quality is controllable. Description of the Drawings
