Description

Brim of a hat sewing machine with mounting fixture

Technical Field

The utility model belongs to the technical field of the technique of sewing machine and specifically relates to a brim of a hat sewing machine with mounting fixture is related to.

Background

The hat, a garment worn on the head, is mainly used for protecting the head by covering the whole top of the head, and has the functions of shading, decorating, warming and the like, so that the hat has a plurality of types and a plurality of choices. The baseball cap is formed by sewing a hemispherical cap body and a semicircular brim, wherein the brim is generally divided into an arc shape and a flat shape, so that the baseball cap can be used for shielding sunlight and has a decorative effect.

Referring to fig. 1, a visor includes a semicircular upper visor cloth 9, a semicircular lower visor cloth 91, and a semicircular visor leather 92 interposed between the upper visor cloth 9 and the lower visor cloth 91, in a conventional visor sewing process, the upper visor cloth 9 is generally stacked on an upper side of the lower visor cloth 91 first, so that the upper visor cloth 9 is aligned with an arc-shaped side of the lower visor cloth 91, and then a worker places the arc-shaped side to be sewn on an upper side of a sewing machine base, and the upper visor cloth 9 and the lower visor cloth 91 are sewn together along an arc-shaped trajectory in a reciprocating lifting process of a sewing machine needle, thereby forming a pocket 93, and then completely turning the inside of the pocket 93 to the outside, and then inserting the semicircular visor leather 92 into the pocket 93, thereby completing a sewing process of a visor.

The sewing machine used in the sewing process is a machine which uses one or more sewing threads to form one or more stitches on a sewing material and enables one or more layers of sewing materials to be interwoven or sewn. The sewing machine most used today is the sewing machine, the most important element of which is the shuttle hook and bobbin assembly, the bobbin being a winding placed under the fabric, which is located in the centre of the shuttle, which is rotated by the motor, synchronized with the movement of the needle, which, like the chain stitch, pulls one loop through the fabric, lifts it again while the feed dog moves the fabric forward, and then inserts another loop, but this sewing mechanism does not connect the different loops together, but connects them with another length of thread unwound from the bobbin, the rotating shuttle seizes the loop with the hook needle when the needle inserts the thread into the loop, and as the shuttle rotates, it pulls the loop around the thread from the bobbin, making the sewing very strong. Therefore, the sewing machine can sew fabrics such as cotton, hemp, silk, wool, artificial fiber and the like, and products such as leather, plastic, paper and the like, the sewed stitch is neat, beautiful, flat and firm, the sewing speed is high, the use is simple and convenient, and artistic forms such as hand-push embroidery, computer embroidery and the like are derived from the sewing machine, wherein the automatic sewing machine is widely applied to industrial production due to the advantages of high efficiency, low working strength and the like.

The traditional Chinese utility model patent with the reference of patent publication No. CN209836521U discloses a sewing machine easy to clamp and capable of preventing thread from being blocked, which comprises a sewing machine base, a sewing machine body, a thread inserting rod, a clamping mechanism, a telescopic rod base and a sewing machine needle, wherein the sewing machine base is rectangular, the sewing machine body is fixedly welded at the center of the left end of the sewing machine base, the head end of the sewing machine body is slidably connected with the telescopic rod base, the bottom of the telescopic rod base is fixedly connected with the sewing machine needle, and the thread inserting rod and the clamping mechanism are respectively arranged on the outer wall of the right side of the sewing machine body from top to bottom; above-mentioned utility model will twine the coil of lines and place on the coil fixing base, the line alternates the pore of telescopic link, the pore of inserted link in proper order, and it is tight with lines fixed clamp to pass through clamping mechanism again, through the clamping action between first clamp and the second clamp among the clamping mechanism, the effectual lines that make are difficult for droing at sewing machine operation in-process for sewing machine efficient operation more.

However, the above prior art solutions have the following drawbacks: when the sewing machine is used for sewing the upper brim cloth and the lower brim cloth, the upper brim cloth and the lower brim cloth which are stacked on the sewing machine base can be sewn together along with the reciprocating lifting of the sewing machine needle, but because the distance between the sewing machine needle and the sewing machine base is smaller, and meanwhile, the sewing area of the upper brim cloth and the lower brim cloth is in an arc shape, the operation of the sewing process is more complex, and the hands of workers are easily pricked by the sewing machine needle in the sewing process.
