Description

Technical Field

[0001] The utility model discloses a hollow fabric splicing device, belonging to the technical field of fabric production and processing. Background Art

[0002] Fabric is the material used to make clothes. As one of the three elements of clothing, fabric can not only interpret the style and characteristics of clothing, but also directly affect the color and shape of clothing. In the world of clothing, clothing fabrics are varied and changing with each passing day. But generally speaking, high-quality and high-end fabrics are mostly comfortable to wear, sweat-absorbent and breathable, drape straight, visually noble, and soft to the touch. When processing and making clothes, fabrics of different materials or patterns need to be seamlessly spliced ​​to improve the beauty of the fabric. The existing fabric splicing usually manually puts two different fabrics together and then splices them by machine. However, when splicing fabrics, it is necessary to manually align and push the two pieces of spliced ​​fabrics into the sewing device. This not only poses certain safety hazards, but also the advancement speed of the two pieces of fabric cannot be well controlled and synchronized, which requires relatively high technical requirements for workers.

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.

[0017] like Figure 1-Figure 3 As shown, a hollow fabric stitching device, the sewing device 3 is located in the middle of the workbench 1, and cloth pressing mechanisms are arranged on both sides of the sewing device 3, the cloth pressing mechanism includes a fixed frame 2, a sliding seat 5, a swing arm 4 and a cloth pressing piece, the fixed frame 2 is fixed on the workbench 1, and a guide rail 21 is arranged on the fixed frame 2, the sliding seat 5 is slidably connected to the guide rail 21, the swing arm 4 is installed on the sliding seat 5, the cloth pressing piece includes a cloth pressing rod 8 and a pressing block 9, one end of the cloth pressing rod 8 is fixedly connected to the swing arm 4, and the other end is hinged to the pressing block 9 through a hinged ball head, the fixed frame 2 is provided with a driving member 6 for driving the sliding seat 5 to slide back and forth along the guide rail 21, and the sliding seat 5 is provided with a power member 7 for driving the swing arm 4 to rotate.

[0018] The driving member 6 includes a plurality of electromagnets 22 distributed at equal intervals, a boss 23 for mounting the electromagnets 22 is provided on the fixing frame 2, a notch 16 is provided in the middle of the sliding seat 5, the lower end of the electromagnet 22 is located in the notch 16, and permanent magnets 24 are provided on both sides of the sliding seat 5 corresponding to the electromagnets 22. The electromagnets 22 generate a changing magnetic field by passing a changing alternating current, and generate a thrust on the permanent magnets 24, so that the sliding seat 5 can be driven to slide in a straight line along the guide rail 21, and drive the swing arm 4 and the cloth pressing member to move, and continuously press and push the two pieces of hollow fabrics, thereby relying on the sewing device 3 to achieve the splicing of the two pieces of hollow fabrics.

[0019] Three pulleys 15 are rotatably mounted on the sliding seat 5. The three pulleys 15 are distributed in a triangle, and the two pulleys 15 located at the bottom have the same height. The three pulleys 15 respectively slide against the upper and lower ends of the guide rail 21. The three pulleys 15 can maintain the stability of the support of the sliding seat 5 and the guide rail 21, and during the sliding process of the sliding seat 5, the pulleys 15 can reduce the sliding resistance of the sliding seat 5 and the guide rail 21.

[0020] The power part 7 includes a motor 13 and a transmission rod 18. The end of the sliding seat 5 away from the guide rail 21 has a concave mounting portion 14, and one end of the swing arm 4 is located in the concave mounting portion 14. The cross-section of the connection between the transmission rod 18 and the swing arm 4 is a non-circular structure. One end of the transmission rod 18 is fixedly connected to the output shaft of the motor 13. The motor 13 drives the transmission rod 18 to rotate forward and backward by a certain angle, so that the swing arm 4 can drive the cloth pressing member to press the hollow fabric and push it to allow the sewing device 3 to sew the two hollow fabrics. When the cloth pressing member moves upward, the hollow fabric can be released and moved to another position to continue to press and push the hollow fabric. Automatic sewing processing can be achieved without manual operation. A guide sleeve 17 cooperating with the transmission rod 18 is provided on the concave mounting portion 14. By providing the guide sleeve 17, the resistance of the transmission rod 18 during rotation can be reduced, so that the rotation of the swing arm 4 is smoother.

[0021] The swing arm 4 includes a first swing member 19, a second swing member 10, a rotating shaft 11, a nut 20 and a torsion spring 12. The first swing member 19 is connected to the transmission rod 18, and the first swing member 19 and the second swing member 10 are rotatably connected through the rotating shaft 11. There are two torsion springs 12 and two nuts 20. The nut 20 is threadedly connected to the rotating shaft 11. A countersunk hole is provided on the second swing member 10, and the torsion spring 12 is located in the countersunk hole. The two ends of the torsion spring 12 are respectively connected to the first swing member 19 and the second swing member 10. The cloth pressing rod 8 is fixedly connected to the second swing member 10. There is a non-zero angle between the first swing member 19 and the second swing member 10. The torsion spring 12 can enable the first swing member 19 and the second swing member 10 to maintain a certain angle state, so that the hollow cloth can be pressed by the pressing block 9. The torsion spring 12 is in a force storage state. When the pressing block 9 is lifted, the angle between the first swing member 19 and the second swing member 10 is reduced, so that it can be prepared for pressing the cloth next time.
