[0022] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0023] like Figure 1-6 As shown, a pressing and positioning mechanism for a cylindrical pattern making machine includes a mounting base 1, a cylinder 2 rotatably connected to the mounting base 1, a connecting ring 3 fixedly sleeved on one end of the cylinder 2 away from the mounting base 1, an arc-shaped support plate 4 fixedly connected inside the cylinder 2 and protruding from the cylinder 2, a guide ring assembly 5 fixedly connected to the connecting ring 3, a main pressing mold assembly 6 fixedly connected to the connecting ring 3, two guide positioning assemblies 7 fixedly connected to the connecting ring 3 and distributed on both sides of the main pressing mold assembly 6, and two auxiliary pressing mold assemblies 8 slidably connected to the guide ring assembly 5 and distributed on both sides of the main pressing mold assembly 6. The arc-shaped support plate 4 is used to support the arc-shaped clamp 9, the guide positioning assembly 7 is used to position the arc-shaped clamp 9, and the main pressing mold assembly 6 and the auxiliary pressing mold assembly 8 are used together to press the arc-shaped clamp 9.

[0024] The material positioning mechanism is mounted on a cylindrical pattern sewing machine via a mounting base 1. In use, the curved clamp 9 clamps and shapes the fabric to be sewn, and the curved support plate 4 supports the curved clamp 9. The guide positioning assembly 7 positions the curved clamp 9, and the main pressing mold assembly 6 and the auxiliary pressing mold assembly 8 jointly press the curved clamp 9, improving its connection stability. When the cylinder 2 rotates, the curved support plate 4, connecting ring 3, guide ring assembly 5, main pressing mold assembly 6, guide positioning assembly 7, and auxiliary pressing mold assembly 8 rotate synchronously with the cylinder 2, keeping the curved clamp 9 in a pressed state at all times. This helps prevent the curved clamp 9 from shifting during sewing, which could cause the sewing thread to deviate. The curved clamp 9 is existing technology and will not be described in detail here.

[0025] Furthermore, the mounting base 1 is recessed with an annular limiting groove 10, and the annular limiting groove 10 accommodates a bearing 11. The cylinder 2 is rotatably connected to the mounting base 1 through the bearing 11.

[0026] Furthermore, the main pressure mold assembly 6 includes a first cylinder seat 61 that passes through and is fixedly connected to the connecting ring 3, a first lifting cylinder 62 connected to one end of the first cylinder seat 61 near the mounting base 1, a first lifting connecting seat 63 connected to the output end of the first lifting cylinder 62, and a main pressure plate 64 fixedly connected to the first lifting connecting seat 63. The bottom surface of the main pressure plate 64 is arc-shaped. When it is necessary to press the arc-shaped clamp 9, the first lifting cylinder 62 drives the first lifting connecting seat 63, causing the main pressure plate 64 to press down onto the arc-shaped clamp 9, so that the arc-shaped clamp 9 is pressed between the main pressure plate 64 and the arc-shaped support plate 4.

[0027] Furthermore, the main compression mold assembly 6 also includes a first vertical plate 65 connected to the end of the first cylinder seat 61 away from the mounting seat 1, a first slide rail 66 fixedly connected to the first vertical plate 65, and a first slider 67 slidably connected to the first slide rail 66. The first lifting connecting seat 63 is fixedly connected to the first slider 67, which helps to prevent the first lifting connecting seat 63 from shifting.

[0028] Furthermore, the guide positioning assembly 7 includes a guide connecting seat 71 fixedly connected to the side of the connecting ring 3 away from the mounting base 1. The guide connecting seat 71 extends with guide blocks 12. The guide blocks 12 of the two guide positioning assemblies 7 cooperate to position the arc-shaped clamp 9. After the arc-shaped clamp 9 is placed on the arc-shaped support plate 4, it is pushed towards the connecting ring 3. The guide blocks 12 of the two guide positioning assemblies 7 position the arc-shaped clamp 9, so that the arc-shaped clamp 9 reaches a specific position, so that the main pressing mold assembly 6 and the auxiliary pressing mold assembly 8 can be used to press the arc-shaped clamp 9 together.

[0029] Furthermore, the guide positioning assembly 7 also includes a second cylinder seat 72 fixedly connected to the side of the connecting ring 3 near the mounting base 1, a push-pull cylinder 73 fixedly connected to the second cylinder seat 72, a hook 74 that movably passes through the connecting ring 3 and the guide connecting base 71 and is connected to the output end of the push-pull cylinder 73, and a limiting seat 75 hinged to the guide connecting base 71. The top of the limiting seat 75 extends with a protruding post 13 for the hook 74 to hook and for the limiting seat 75 to rotate backward. The bottom of the limiting seat 75 extends with a limiting post 14 for limiting and engaging with the arc-shaped clamp 9. The side of the limiting seat 75 away from the guide connecting base 71 extends with a braking block 15 for abutting and braking against the bottom of the hook 74. After the guide blocks 12 of the two guide positioning components 7 position the arc-shaped clamp 9, the push-pull cylinder 73 pushes the hook 74 forward. The hook 74 hits the brake block 15, causing the limiting seat 75 to rotate forward until the limiting post 14 engages with the arc-shaped clamp 9. Under the action of the hook 74 and the brake block 15, the limiting seat 75 is prevented from rotating backward. When it is necessary to remove the arc-shaped clamp 9, the push-pull cylinder 73 pulls the hook 74 backward. The hook 74 hooks the protrusion 13 and causes the limiting seat 75 to rotate backward. The limiting post 14 disengages from the arc-shaped clamp 9, thus releasing the limiting post 14 from the limiting engagement with the arc-shaped clamp 9. Specifically, the arc-shaped clamp 9 has a limiting opening 16 that engages with the limiting post 14.

[0030] Furthermore, the guide ring assembly 5 includes a helical toothed ring 51 fixedly sleeved on the outer periphery of the connecting ring 3, and an annular guide rail 52 fixedly connected to the side of the connecting ring 3. The auxiliary pressing mold assembly 8 engages with the helical toothed ring 51 for transmission, and the auxiliary pressing mold assembly 8 is slidably connected to the annular guide rail 52. Based on the distance between the two ends of the arc-shaped clamp 9, the auxiliary pressing mold assembly 8 moves along the annular guide rail 52 to adjust its position, so that the two auxiliary pressing mold assemblies 8 press against the two ends of the arc-shaped clamp 9, which helps to keep the arc-shaped clamp 9 stable during the sewing process.

[0031] Furthermore, the auxiliary pressure mold assembly 8 includes a second upright plate 81, an upper roller assembly 82 rotatably mounted on the second upright plate 81, a lower roller assembly 83 rotatably mounted on the second upright plate 81, a motor base 84 fixedly connected to the second upright plate 81, a stepper motor 85 fixedly connected to the motor base 84, a helical gear 86 fixedly connected to the output end of the stepper motor 85 and meshing with the helical gear ring 51, a second lifting cylinder 87 fixedly connected to the second upright plate 81, a second lifting connecting seat 88 fixedly connected to the output end of the second lifting cylinder 87, and an auxiliary pressure plate 89 fixedly connected to the second lifting connecting seat 88. The bottom surface of the auxiliary pressure plate 89 is arc-shaped, and the upper roller assembly 82 and the lower roller assembly 83 slide in cooperation with the upper and lower sides of the annular guide rail 52, respectively.

[0032] Furthermore, the auxiliary pressure mold assembly 8 also includes a second slide rail 810 fixedly connected to the second vertical plate 81, and a second slider 811 slidably connected to the second slide rail 810. The second lifting connecting seat 88 is fixedly connected to the second slider 811, which helps to prevent the second lifting connecting seat 88 from shifting.

[0033] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this utility model are within the protection scope of this utility model.
