Technical Field

[0001] The utility model relates to the technical field of sewing machines, in particular to a sewing machine with a positioning structure. Background Art

[0002] Sewing is a crucial process in modern industrial production. Traditional sewing machines typically require manual labor, which presents several significant drawbacks. First, manual sewing of synthetic fabrics relies heavily on operator proficiency and efficiency, leading to significant fluctuations in production efficiency. Furthermore, prolonged, repetitive work can easily lead to operator fatigue, compromising accuracy and stability. Furthermore, manual operation in large-scale production results in high labor costs. With rising labor costs, this has placed significant financial pressure on businesses.

[0003] In some sewing machines with a slightly higher degree of semi-automation, workers load the materials and the sewing machines automatically sew the synthetic fabrics, which improves production efficiency to a certain extent. However, the positioning effect of existing semi-automatic sewing machines is poor. The synthetic fabrics will deviate when they are loaded and sewn, causing the sewing machine to deviate, resulting in uneven sewing quality of the synthetic fabrics. Summary of the Invention

DETAILED DESCRIPTION

[0016] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0017] See also Figures 1 to 3 The utility model provides a sewing machine with a positioning structure, including a base plate 1, a fastener 2, a transmission member 3, a conveyor belt 4, a sewing machine head 5, a first sensor 6 and a first pneumatic positioning member 7; the conveyor belt 4 is arranged on one side of the sewing machine head 5, the transmission member 3 is arranged at the bottom of the conveyor belt 4, the base plate 1 is arranged on one side of the conveyor belt 4 and the sewing machine head 5, the fastener 2 is arranged on one side of the base plate 1, the first sensor 6 is fixedly connected to the sewing machine head 5, and is located on the side of the sewing machine head 5 close to the conveyor belt 4, and the first pneumatic positioning member 7 is arranged on one side of the sewing machine head 5.

[0018] In this embodiment, the base plate 1 provides installation conditions for the fastener 2. The fastener 2 adopts a hinge star structure, which is used to fix the four sides of the synthetic cloth and fix the synthetic cloth on the base plate 1. The transmission member 3 (a power transmission structure of a sampling gear driving a belt, which is a prior art) is used to drive the conveyor belt 4 to operate. The conveyor belt 4 is used to convey the base plate 1 to the sewing machine head 5. After the base plate 1 enters the sewing machine head 5, the base plate 1 is guided and positioned by the first pneumatic positioning member 7. The sensor 6 (existing technology) detects whether the base plate 1 reaches the specified position of the sewing machine head 5. At this time, the sewing machine head 5 operates based on a preset program control to sew the synthetic fabric fixed on the base plate 1. The sewing machine first fixes the synthetic fabric through the fastener 2 and then guides and positions it through the first pneumatic positioning member 7, thereby performing double positioning of the sewn synthetic fabric, ensuring the sewing accuracy of the sewing machine head 5, avoiding the occurrence of sewing deviation, and solving the problems of poor positioning effect and sewing deviation of the sewing machine.

[0019] Furthermore, the sewing machine with a positioning structure also includes a second pneumatic positioning member 8 and a positioning column 9. The second pneumatic positioning member 8 is arranged on the side of the conveyor belt 4 away from the transmission member 3, and the positioning column 9 is arranged on the side of the conveyor belt 4 close to the second pneumatic positioning member 8.

[0020] In this embodiment, when the conveyor belt 4 transports the base plate 1, the second pneumatic positioning member 8 and the positioning column 9 are used in conjunction to guide and position both sides of the base plate 1 to prevent the base plate 1 from shifting during transportation.

[0021] Furthermore, the sewing machine with a positioning structure further includes a second sensor 10 , which is fixedly connected to the conveyor belt 4 and is located on a side of the conveyor belt 4 close to the sewing machine head 5 .

[0022] In this embodiment, the second sensor 10 (existing technology) is used to detect whether the bottom plate 1 leaves the conveyor belt 4 .

[0023] Furthermore, the second pneumatic positioning member 8 includes a cylinder 11, a piston 12, a connecting rod 13 and a clamp 14. The cylinder 11 is fixedly connected to the conveyor belt 4 and is located on one side of the conveyor belt 4. The piston 12 is arranged on one side of the cylinder 11. The connecting rod 13 is fixedly connected to the piston 12 and is located on the side of the piston 12 away from the cylinder 11. The clamp 14 is fixedly connected to the connecting rod 13 and is located on the side of the connecting rod 13 away from the piston 12.

[0024] In this embodiment, the second pneumatic positioning member 8 and the first pneumatic positioning member 7 have the same structure. When the pneumatic clamping device is started, compressed air is introduced into the cylinder. Under the action of air pressure, the piston 11 performs linear motion in the cylinder 11. The movement of the piston 12 is transmitted to the clamping jaw 14 through the connecting rod 13. The connecting rod 13 converts the linear motion of the piston 12 into the opening and closing action of the clamping jaw 14. When it is necessary to clamp the base plate 1, the piston 12 pushes the connecting rod forward, causing the clamping jaw 14 to move inward. When closed, the base plate 1 is tightly clamped, thereby achieving the positioning of the base plate 1. The clamping jaws 14 can provide a stable and uniform clamping force to prevent the base plate 1 from moving or shaking. When the base plate 1 needs to be released, the direction of the compressed air is changed, and the piston 11 moves backward, driving the clamping jaws 14 to open outward and release the base plate 1 through the connecting rod 13. By controlling the air pressure in the cylinder 11 and the gas inlet and outlet time, the movement speed, strength and accuracy of the clamping jaws 14 can be adjusted to meet different positioning requirements of the base plate 1.

[0025] Furthermore, the sewing machine head 5 includes a mounting frame 15, a sewing head 16 and a sewing table 17. The sewing table 17 is arranged on one side of the conveyor belt 4. The mounting frame 15 is fixedly connected to the sewing table 17 and is located on the top of the sewing table 17. The sewing head 16 is arranged on one side of the mounting frame 15.

[0026] In this embodiment, the sewing table 17 provides installation conditions for the mounting frame 15 and the first sensor 6. The mounting frame 15 installs and supports the sewing head 16. The sewing head 16 can move on the mounting frame 15 and sew the synthetic fabric fixed on the base plate 1 based on a preset program control.

[0027] The above disclosure is only a preferred embodiment of a sewing machine with a positioning structure of the present application, and cannot be used to limit the scope of rights of the present application. Ordinary technicians in this field can understand that implementing all or part of the processes of the above embodiment and making equivalent changes in accordance with the claims of this application still fall within the scope covered by this application.
