[0031] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] See also Figures 1 to 3 , the utility model embodiment discloses an auxiliary device for sewing feathers, including a connecting member 1, a presser foot member 2 and a blocking member 3;

[0033] The connecting member 1 and the presser foot member 2 are rotatably connected via a rotating shaft 4. The connecting member 1 is provided with a mounting groove 11 for connecting to a sewing machine. The front end of the presser foot member 2 is provided with a sewing groove 22 formed by a middle portion 21.

[0034] The blocking member 3 includes a fitting portion 31 and a baffle portion 32. The fitting portion 31 is installed on the bottom of the presser foot member 2. The fitting portion 31 is located below the sewing 22 and has an organic needle hole 33. The baffle portion 32 is integrally formed with the fitting portion 31 and is arranged on one side of the presser foot member 2.

[0035] Specifically, the fitting portion 31 and the baffle portion 32 of the blocking member 3 are respectively used to deal with the situation where the feather is caught in the needle position and the needle is stuck to the glue on the feather stem. A needle hole 33 is arranged on the fitting portion 31 corresponding to the needle position. When the needle is inserted into the feather stem and glue is attached, the edge of the needle hole 33 will scrape the glue attached to the needle away from the needle, so as to prevent the glue from clogging the needle eye and causing thread breakage, thereby interrupting the sewing process and affecting the sewing production efficiency.

[0036] Furthermore, the baffle portion 32 is connected to the fitting portion 31. During the sewing process, the baffle portion 32 can press down all the feathers on the seam side of the feather fabric to be sewn outside the seam, thereby preventing the feathers from being caught in the seam and causing thread breakage, thereby reducing the impact of interrupting the sewing process on production efficiency.

[0037] Furthermore, the blocking member 3 can be integrally formed or split-formed. In the present embodiment, the integrally formed production cost is relatively low. By selecting a piece of presser foot glue as the blocking member 3 for processing, the presser foot glue only needs to be attached to the bottom of the presser foot member 2 for installation, and a machine needle is used to process a needle hole 33 at the needle hole located under the machine needle. At the same time, a heating device (such as a lighter) can be used to heat the edge of the presser foot glue located at the presser foot member 2, so that the presser foot glue is processed into the baffle portion 32 in the blocking member 3 through plastic deformation, and then the bottom of the presser foot glue is polished into a smooth plane and can be put into use. After reading the present application, it is easy for technical personnel in this field to know that the use of other materials (such as metal) instead of presser foot glue can also achieve the technical effect achieved by the present application, and the choice of integral molding and split molding of the blocking member 3 can be changed according to the actual material and usage requirements, and both can achieve the purpose of avoiding thread breakage caused by sewing feathers and reducing the impact of interrupting the sewing process on production efficiency in the present application.

[0038] As a preferred embodiment, the cross-section of the connection between the fitting portion 31 and the baffle portion 32 is arc-shaped. The arc-shaped connection formed by the arc-shaped cross-section can increase the degree of depression of the blocking member 3 on the feather, and further enhance the ability of the baffle portion 32 to prevent the feather from being rolled into the needle eye position of the machine needle.

[0039] As a preferred embodiment, the bottom surfaces of the fitting portion 31 and the baffle portion 32 are both smooth surfaces. The fabric needs to be moved during the sewing process, and the smooth bottom surface can reduce the resistance generated by the friction between the blocking member 3 and the fabric when the fabric is moved, thereby improving production efficiency.

[0040] As a preferred embodiment, the width of the blocking member 3 is greater than the width of the presser foot member 2, and the length of the blocking member is not less than the length of the presser foot member 2. The actual size of the blocking member 3 is determined according to the size of the presser foot. The blocking member 3 only needs to ensure that it can fit the bottom of the presser foot member 2 while leaving space for the baffle portion 32.

[0041] As a preferred embodiment, a spring groove 12 is provided at the bottom of the connecting member 1, and a buffer spring 5 is installed in the spring groove 12, which respectively abuts against the connecting member 1 and the presser foot member 2. The buffer spring 5 can effectively reduce the mechanical wear of the presser foot caused by the machine needle when working, thereby extending the service life of the production tool.

[0042] As a preferred embodiment, the caliber of the needle hole 33 is the same as the inner diameter of the needle. The thickness of the needle can be made the same through the needle hole 33, which can facilitate the fitting part 31 to scrape off the glue attached to the needle at the needle hole 33, avoiding the glue from entering the needle eye position under the needle and clogging the needle eye, thereby avoiding production interruption caused by thread breakage, thereby improving production efficiency.

[0043] The utility model provides a blocking piece at the bottom of the sewing machine presser foot, so that when sewing feathers, the feathers of the sewing position attachment are limited to the other side through the baffle part, so as to prevent the feathers from being caught in the needle eye position of the machine needle and causing thread breakage. The utility model has a simple use method and can be used in production without the need for employees to invest learning costs, which can further improve the production efficiency of the process of sewing feather fabrics. By providing a blocking piece at the bottom of the sewing machine presser foot, the glue brought out by the machine needle when the feather stem is inserted will be rubbed off at the machine needle hole, which can reduce the occurrence of thread breakage caused by the machine needle sticking to the glue on the feather stem. The blocking piece has a simple structure and is easy to process, which can further improve the production efficiency of the process of sewing feather fabrics.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
