[0002] 3D computer pattern sewing machines, including cylindrical pattern sewing machines, have a cylindrical drive structure and are high-end sewing equipment that integrates computer control, precision mechanics and automation technology. They are designed specifically for sewing three-dimensional curved surfaces. When in use, the cylinder is driven to rotate at a certain angle to sew three-dimensional fabrics such as the curved surfaces of shoe heels.

The arc-shaped support plate 3 is used to support the lower arc-shaped clamping mold 13 of the arc-shaped fixture, the mold guiding assembly 6 is used to guide and limit the lower arc-shaped clamping mold 13 of the arc-shaped fixture, and the output end of the mold positioning drive assembly 4 presses against the mold locking group 5 and is used to drive the mold locking group 5 to lock the lower arc-shaped clamping mold 13 of the arc-shaped fixture.

[0021] The material placement mechanism is mounted on a cylindrical pattern-making machine via a fixed base 1. When using the lower arc-shaped clamping mold 13 and the upper clamping mold of the arc-shaped clamp to shape the fabric to be sewn, the lower arc-shaped clamping mold 13 of the arc-shaped clamp is placed on the arc-shaped support plate 3 for support. The mold guiding component 6 guides and limits the lower arc-shaped clamping mold 13 of the arc-shaped clamp. Then, the mold positioning drive component 4 drives the mold locking group 5 to lock the lower arc-shaped clamping mold 13 of the arc-shaped clamp, preventing the lower arc-shaped clamping mold 13 from shifting and affecting the placement and positioning of the fabric to be sewn.

[0022] Furthermore, an arc-shaped extension plate 7 extends from the top of one side of the bending connecting seat 2, and a support block 8 is connected to the bottom of the bending connecting seat 2. The arc-shaped support plate 3 is fixedly connected to the arc-shaped extension plate 7 and the support block 8.

[0023] Furthermore, the mold positioning drive assembly 4 includes a cylinder seat 41 fixedly connected to one side of the bending connecting seat 2, and a first drive cylinder 42 fixedly connected to the cylinder seat 41. The output end of the first drive cylinder 42 presses against the mold locking assembly 5 and is used to drive the mold locking assembly 5 to lock the lower arc-shaped clamping mold 13 of the arc surface fixture.

[0024] Furthermore, the mold locking assembly 5 includes a vertical plate 51 slidably disposed on one side of the bending connecting seat 2, a bending block 52 fixedly connected to one side of the vertical plate 51 and extending to the bottom of the output end of the mold positioning drive assembly 4, a first bolt 53 fixedly connected to the bending connecting seat 2 and located above the vertical plate 51, a second bolt 54 fixedly connected to the vertical plate 51, a tension spring 55 sleeved on the first bolt 53 and the second bolt 54, two first bending arms 56 fixedly connected to both ends of the vertical plate 51, and a positioning bolt 57 connected to the top of the first bending arm 56. The output end of the first drive cylinder 42 presses against the bending block 52. The top of the bending connecting seat 2 is provided with a clearance opening 9 for the first bending arm 56 to pass through. The positioning bolt 57 is used to lock the lower arc-shaped clamping mold 13 of the arc-shaped fixture. After the mold guide assembly 6 guides the lower arc-shaped clamping mold 13 of the limiting arc-shaped fixture, the output end of the first drive cylinder 42 descends, driving the bending block 52 to descend. The bending block 52, the upright plate 51, the first bending arm 56, and the positioning bolt 57 descend synchronously until the positioning bolt 57 locks into place with the lower arc-shaped clamping mold 13 of the arc-shaped fixture, preventing the lower arc-shaped clamping mold 13 from shifting and affecting the positioning of the fabric to be sewn. Specifically, the lower arc-shaped clamping mold 13 has a limiting opening 14 that locks into place with the positioning bolt 57. When it is necessary to release the lock, the first drive cylinder 42 stops operating, and under the action of the tension spring 55, the upright plate 51, the bending block 52, the first bending arm 56, and the positioning bolt 57 rise synchronously, and the output end of the first drive cylinder 42 is lifted a certain distance by the bending block 52.

[0025] Furthermore, the material handling mechanism also includes a Z-axis slide rail 10 fixedly connected to one side of the bending connecting seat 2, and a slider 11 that slides with the Z-axis slide rail 10, wherein the upright plate 51 is fixedly connected to the slider 11.

[0026] Furthermore, the mold guiding assembly 6 includes two second bending arms 61 fixedly connected to the top of the other side of the bending connecting seat 2, and bolt roller bearings 62 connected to the top of the second bending arms 61. The two second bending arms 61 are distributed on both sides of the mold locking assembly 5, and the two bolt roller bearings 62 cooperate to guide the lower arc-shaped clamping mold 13 of the limiting arc-shaped fixture. After the lower arc-shaped clamping mold 13 of the arc-shaped fixture is placed on the arc-shaped support plate 3, it is pushed towards one side of the bending connecting seat 2. The bolt roller bearings 62 of the two second bending arms 61 cooperate to guide the lower arc-shaped clamping mold 13 of the limiting arc-shaped fixture, so that the lower arc-shaped clamping mold 13 of the arc-shaped fixture reaches a specific position, so that the mold positioning drive assembly 4 can then drive the mold locking assembly 5 to lock the lower arc-shaped clamping mold 13 of the arc-shaped fixture.

[0027] Furthermore, the material placement mechanism also includes a pressing mold assembly 12 fixedly connected to the other side of the bending connecting seat 2, the pressing mold assembly 12 being used to press the arc-shaped fixture.

[0028] Furthermore, the pressing mold assembly 12 includes a second driving cylinder 121 fixedly connected to the other side of the bending connecting seat 2, a horizontal plate 122 fixedly connected to the output end of the second driving cylinder 121 at one end, a connecting block 123 fixedly connected to the bottom of the other end of the horizontal plate 122, and two pressing mold columns 124 fixedly connected to the bottom ends of the connecting block 123. The two pressing mold columns 124 are used to press the arc-shaped clamping fixture. After the fabric to be sewn is positioned on the lower arc-shaped clamping mold 13 of the arc-shaped clamping fixture, the upper arc-shaped clamping mold is placed on the fabric to be sewn and positioned. The second driving cylinder 121 drives the horizontal plate 122 to drive the connecting block 123 and the pressing mold columns 124 to press down, so that the upper arc-shaped clamping mold is pressed and locked onto the lower arc-shaped clamping mold 13.

[0029] 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.
