Description

Technical Field

[0001] The utility model relates to the technical field of knitted fabric sewing, in particular to an edge sewing mechanism for knitted fabrics. Background Art

[0002] In the production process of modern knitted fabrics, the edge of knitted fabrics is mainly sealed by wrapping and sewing the edges of the knitted fabrics. Therefore, in the process of sewing the edges, the fabric used for the hemming needs to be pre-cut to make its length match the edge length of the knitted fabric. Therefore, in the operation process, the two sides of the hemming must be symmetrical to avoid the problem that one side of the hemming cannot be sewn during sewing. At this stage, how to plan the symmetrical folding of the hemming mostly depends on the control of workers. This requires not only that the workers can align the hemming, but also that the workers can effectively prevent the edge of the knitted fabric from being difficult to operate on the fold line of the hemming, which affects production efficiency and increases the difficulty of workers' operation. In view of this, in-depth research was conducted on the above-mentioned issues, resulting in this case. Utility Model Content

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-3 The utility model provides an implementation scheme: in the modern knitting industry, the edges of knitted fabrics are mostly sewn and sealed with an edge binding structure. In the process of sewing and sealing, the alignment of the edge binding is mainly manual alignment at this stage. The fabric is pushed while the edge binding is pushed through the sewing machine, which is inconvenient to operate. Therefore, the application discloses an edge sewing mechanism for knitted fabrics. The sewing base 1 is fixed on the sewing machine. A thread routing groove for the insertion of the suture needle is arranged on the sewing base 1. The sewing position completes the sewing of the knitted edge and the edge binding through the thread routing groove under the back and forth insertion of the suture needle. In order to solve the problem that the edge binding needs to be folded in half and then the edge of the fabric is wrapped and pushed inconveniently, the application opens a straight line groove 3 on one side of the needle routing groove 2 of the sewing base 1. The straight line groove 3 is a through groove of a rectangular structure. An edge binding and curling mechanism is arranged through the straight line groove 3. The edge binding and curling mechanism carried by the straight line groove 3 is used to fold the edge binding.

[0021] According to the instruction manual Figure 1-3 It can be known that in the specific implementation process, the hemming and curling mechanism includes a sliding seat 4, which is assembled in the linear groove 3. The sliding seat 4 can slide in the linear groove 3, and then push the hemming and the knitted fabric through the needle groove 2. A pair of sliding seats 5 are symmetrically arranged at both ends of the sliding seat 4, and an elastic clamping claw 6 is installed on each of the pair of sliding seats 5. The elastic clamping claw 6 can adopt a threaded structure to control and clamp the midpoints of the two ends of the hemming. A pair of threaded holes are opened on the pair of sliding seats 5, which are respectively engaged with the symmetrical threads of the coaxial bidirectional screw rod 7. The coaxial bidirectional screw rod 7 is engaged with the threaded holes to control the relative movement of the pair of sliding seats 5 on the sliding seat 4, so that the pair of sliding seats 5 pull the hemming to be straight, and then the knitted fabric is placed on the side close to the center line of the hemming.

[0022] According to the attached drawings in the specification, one side of the sliding seat 4 is hinged with an electric buckle plate 10, which can be flipped 180°. The flipped electric buckle plate 10 is pressed on the center line of a pair of sliding seats 5. By controlling the state of the electric buckle plate 10, it is flipped 180°, so that the hemming originally laid flat on the electric buckle plate 10 is flipped to one side of the knitted fabric, and then the hemming is folded in half and pressed on the other side of the knitted fabric. At the same time, corresponding to the linear groove 3, a slide rail 8 is provided on the bottom surface of the sewing base 1 and wrapped around the sliding seat 4. A control cylinder 9 is provided at one end of the slide rail 8, and the telescopic end of the control cylinder 9 is connected to the sliding seat 4. The extension of the control cylinder 9 pushes the sliding seat 4 to move linearly in the slide rail 8 through one side of the needle groove 2. The needle groove 2 is located at the edge after the hemming is folded in half, and the sewing is completed by the sewing needle. In this way, the hands only need to support the knitted fabric to move forward, and the operation is simpler and more convenient.

[0023] As a preferred solution, further, the pushing direction of the control cylinder 9 is toward the needle groove 2 side.

[0024] As a preferred solution, further, the electric buckle plate 10 is a rectangular structured plate and is movably mounted on the sliding seat 4 at both ends by a pair of hinges. The electric buckle plate 10 is driven by a limit motor and rotates around the hinges. At the same time, when the electric buckle plate 10 is buckled to the edge, its edge should be at least 5 mm away from the center line of the needle groove 2, that is, the edge after folding should expose at least 105 mm of the electric buckle plate.

[0025] As a preferred solution, further, the power of the coaxial bidirectional screw 7 comes from the stepper motor 11, and the stepper motor 11 is connected to the manual control button. The stepper motor 11 is driven to rotate by the manual control button, so that the stepper motor 11 drives the coaxial bidirectional screw 7 to rotate.

[0026] As a preferred solution, further, the pair of slide seats 5 is a pair of rectangular structured plates, and the elastic clamping claws 6 is a pair of elastic narrow-edge clamping structures to avoid clamping too much of the center line of the edging.

[0027] As a preferred solution, further, the straight groove 3 extends through one side of the needle groove 2.

[0028] From the above, it can be generally known that the edge sewing mechanism for knitted fabrics adopts a cylinder-controlled sliding seat 4 as a feeding and pushing device to complete the advancement of the edge during sewing. At the same time, relatively moving clamping devices are arranged at both ends of the sliding seat 4 to clamp the center line of the edge. With the flipping function of the electric buckle plate 10, the edge can be folded in the center. On the one hand, it can buckle the edge of the edge and the knitted fabric, and on the other hand, it can help feeding. The operation is more convenient and the structure is simpler.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
