Description

Technical Field

[0001] The utility model belongs to the technical field of sewing equipment and relates to a wire dividing piece of a sewing machine and a sewing machine. Background Art

[0002] The rotary shuttle and the needle play a vital role in the process of sewing fabrics to form stitches. Usually, the rotary shuttle is set under the needle plate of the sewing machine, including the outer shuttle frame, the inner shuttle frame, the pressure plate and the positioning hook, etc. The outer shuttle frame is fixed on the lower shaft, and rotates circumferentially with the up and down movement of the needle, and rotatably supports the inner shuttle frame.

[0003] In order to separate the surface thread, a dividing piece is often provided near the rotary hook device. Regarding the function and installation position of the dividing piece, reference may be made to the connection structure between the disengagement mechanism of the rotary hook surface thread and the working platform in a mold transporting machine disclosed in application number 201420114502.2.

[0004] During the sewing process, when the upper thread passes around the rotary shuttle at high speed, due to inertia, the upper thread is sometimes thrown too long, and the thread dividing plate in the prior art has a single structure and it is difficult to block the thrown upper thread, resulting in the appearance of thrown points in the stitches of the upper thread sewn on the fabric (the excessively long upper thread forms a semicircle or partial circle after sewing). Summary of the invention

[0005] The utility model aims at the above problems existing in the prior art and provides a thread dividing piece for a sewing machine. The technical problem to be solved by the utility model is: how to prevent the occurrence of throwing points on the fabric.

[0006] The purpose of the utility model can be achieved through the following technical solutions:

[0007] A wire dividing plate for a sewing machine, comprising a plate body 1, characterized in that a plate body 2 is arranged on one side of the plate body 1, the plate body 2 extends from top to bottom, and when the plate body 1 is installed on a casing, the plate body 2 is located on one side of a rotary hook.

[0008] When in use, the sheet one in the thread dividing sheet is used to be installed on the casing of the sewing machine. After installation, the sheet two is located on one side of the rotary shuttle. The sheet two extends from top to bottom, and it is closer to the rotary shuttle. Therefore, when the upper thread is thrown too long when passing around the rotary shuttle at high speed, the sheet two can block the upper thread that is thrown too long, play a role in protecting the thread, prevent the occurrence of throwing points on the sewing track on the fabric, and improve the sewing effect.

[0009] In the above-mentioned thread dividing plate of a sewing machine, the second plate body is arc-shaped and extends along the outer shuttle frame of the rotary shuttle.

[0010] The outer shuttle frame of the rotary shuttle is basically annular, and the arc-shaped piece two is closer to the shape of the outer shuttle frame. The piece two extends along the outer shuttle frame. This structure makes the piece two closer to the outer shuttle frame, which has a good blocking effect on the opposite line, better prevents the occurrence of throwing points on the fabric, and improves the sewing effect.

[0011] In the above-mentioned wire dividing plate of a sewing machine, the upper end of the second plate is connected to the first plate, and the lower end of the second plate has a convex edge extending outward, and the convex edge extends horizontally or extends obliquely downward.

[0012] A convex edge extending horizontally or downwardly is provided on the second sheet body, and the convex edge increases the length of the second sheet body. This structure can block the longer surface thread, prevent the occurrence of throwing points on the sewing track on the fabric, and improve the sewing effect.

[0013] In addition, when the convex edge extends downward, it not only increases the length of the second sheet, but also makes the convex edge closer to the outer shuttle frame of the rotary shuttle, so that the second sheet can better block the surface line, prevent the occurrence of throwing points on the fabric, and further improve the sewing effect.

[0014] In the above-mentioned thread dividing plate of a sewing machine, the plate body 1 and the plate body 2 are an integrally formed structure.

[0015] The sheet body 1 and the sheet body 2 are an integrated structure, and the branching sheet of this structure has higher strength and is easy to process.

[0016] In the above-mentioned wire dividing plate of a sewing machine, a mounting hole for the bolt to pass through is arranged on the plate body.

[0017] During installation, the bolts pass through the installation holes and are threadedly connected to the casing, thereby fixing the sheet body on the casing. This structure greatly improves the convenience of installation.

[0018] The utility model also provides a sewing machine, which comprises any one of the above-mentioned wire dividing pieces.

[0019] Compared with the prior art, the advantages of the utility model are as follows:

[0020] 1. The second piece of the thread dividing piece extends from top to bottom, and it is closer to the rotary shuttle. The second piece can block the upper thread that is thrown too long, play a role in protecting the thread, prevent the sewing track on the fabric from throwing points, and improve the sewing effect.

[0021] 2. The convex edge of the dividing piece increases the length of the second piece, which can block the longer surface thread, prevent the sewing track on the fabric from being thrown, and improve the sewing effect. BRIEF DESCRIPTION OF THE DRAWINGS
