[0030] The present invention will be further described below with reference to specific embodiments. See also: Figure 1 —9:

[0031] This utility model provides a distance-adjustable feeding device, which includes a platform 1 and a machine head 2 disposed on the platform 1; a feeding module 3 is disposed on the platform 1 along the feeding direction on one side of the machine head 2, and a feeding plate 4 is mounted on the feeding module 3. The feeding plate 4 is driven by the feeding module 3 to reciprocate along the feeding direction; the front and rear end areas of the feeding plate 4 are respectively provided with a front clamping component and a rear clamping component for clamping the sewing material; a laser positioning light 5 is installed on the machine head 2 or the platform 1, and the illumination light path of the laser positioning light 5 is pointed to the upper surface of the sewing material on the feeding plate 4, for checking whether there is any offset in the position from the buttonhole to the side of the sewing material.

[0032] This invention can be directly used with electronic buttonhole machines. It provides a precise visual reference through a laser positioning light, and combined with an automated feeding module and front and rear clamping components, it achieves rapid and accurate positioning of the buttonhole and stable, automatic feeding of the sewing material. Its adjustable distance design allows the device to flexibly adapt to different processing requirements, significantly improving positioning accuracy, processing efficiency, and adaptability when used with electronic buttonhole machines.

[0033] It should be noted that "front and back" here refers to the feeding direction. Taking the operator facing the machine head 2 as a reference, the end closer to the operator is the front, and the end farther from the operator is the back. Correspondingly, the left and right directions are defined as the operator's left side as the left and the right side as the right.

[0034] As one embodiment of the front-end clamping assembly, the front-end clamping assembly includes an adjustment module 6 fixed below the front end of the feeding plate 4 and a movable plate 8 fixedly connected to a slider 7 of the adjustment module 6. The adjustment module 6 drives the movable plate 8 to reciprocate along the feeding direction, thereby achieving automatic adjustment of the position of the movable plate 8. A first driving member 9 is fixedly installed on the movable plate 8, and a front pressure cloth plate 10 is connected to the actuating end of the first driving member 9. The front pressure cloth plate 10 is driven by the first driving member 9 to cooperate with the movable plate 8 to press the cloth. A first signal button 11 for controlling the action of the first driving member 9 is also fixedly installed on the movable plate 8. The first signal button 11 is electrically connected to an electronic control system. In this embodiment, the first driving member 9 is a first cylinder, and the actuating end is a piston rod. In addition, a stepper motor combined with a lead screw can also replace the first cylinder.

[0035] Another implementation of the front-end clamping assembly differs primarily in the method of fixing the movable plate 8. In this implementation, the movable plate 8 is manually adjusted in position on the feeding plate 8. Specifically, a slotted hole is provided on the feeding plate 4, which is used to adjust the forward and backward position of the movable plate 8 along the movement path of the feeding plate 4. Fasteners are detachably installed on the movable plate 8 through the slotted hole, thus achieving the installation of the feeding plate 4 and the movable plate 8. Specifically, the fastener is a screw, and a corresponding threaded hole is provided on the movable plate 8 for screwing into it.

[0036] In order to achieve alignment of the sides, the present invention provides a front baffle block 12 on the movable plate 8.

[0037] Furthermore, the rear clamping assembly of this utility model includes a rear pressure plate 13 and a second driving member 14 fixed to the rear end of the feeding plate 4. The actuating end of the second driving member 14 is connected to the rear pressure plate 13, and the second driving member 14 drives the rear pressure plate 13 to cooperate with the feeding plate 4 to press the fabric. A second signal button 15 for controlling the action of the second driving member 14 is provided on the rear pressure plate 13. The second signal button 15 is also electrically connected to the electronic control system.

[0038] Furthermore, the rear pressing plate 13 is n-shaped and has two first arms 16 and second arms 17 arranged at an interval. The lower ends of the first arms 16 and the second arms 17 are bent to both sides to form a first bent portion 18 and a second bent portion 19, respectively. The first bent portion 18 cooperates with the feeding plate 4 to press the cloth, and the second bent portion 19 is connected to the execution end of the second driving member 14.

[0039] In this embodiment, the second driving component 14 is a second cylinder, and the actuating end is a piston rod. Alternatively, a stepper motor combined with a lead screw can also replace the second cylinder.

[0040] To facilitate adjustment of the left and right positions of the back pressing plate 13, this utility model also provides a waist-shaped hole on the second bending part.

[0041] Furthermore, this utility model provides a rear baffle block 20 on the feeding plate 4 on one side of the rear pressure plate 13. The rear baffle block 20 is L-shaped, with the portion arranged in the left and right directions serving as a reference positioning point for the sewing material in the front and back directions, and the portion arranged in the front and back directions cooperating with the front baffle block 12 to serve as a reference positioning point for the sewing material in the left and right directions.

[0042] This invention also includes a protective tube 21 fixedly installed on the platform 1. The area enclosed by the protective tube 21 is larger than the maximum range of motion of the front end of the feeding plate 4. The protective tube 21 serves as a safety protection, preventing the feeding plate 4 from injuring the operator during its forward movement.

[0043] The laser positioning light 5 of this utility model is fixedly installed on the machine head 2 or the platform 1 by a light mounting base 22.

[0044] Furthermore, the feeding module 3 is fixedly connected to the platform 1 via a module connecting plate 23.

[0045] The feeding plate 4 of this invention is also provided with a feeding rack 24 on one side. When sewing heavy fabric, placing the fabric on the feeding rack 24 can prevent the fabric from being pulled off the sewing position due to its weight.

[0046] The working principle of this utility model is as follows:

[0047] When the position of the movable plate 8 is automatically adjusted, the operator can directly set the corresponding size of the garment on the electronic control screen. The adjustment module 6 will automatically adjust the position of the movable plate 4 back and forth according to the set size, thereby changing the distance between the front pressure plate 10 and the rear pressure plate 13. After the operator places the fabric in the corresponding position, pressing the first signal button 11 and the second signal button 15 will activate the corresponding first and second cylinders, causing the front pressure plate 10 to press down in conjunction with the movable plate 8 to press the fabric, and the rear pressure plate 13 to press down in conjunction with the feed plate 4 to press the fabric. After clamping the fabric at both ends, the laser positioning light 5 is used to inspect the buttonhole sewing position for any deviation. If there is a deviation, the fabric is moved to make adjustments.

[0048] When manually adjusting the position of the moving plate 8, the operator loosens the fasteners securing the moving plate 8 according to the length of the fabric, adjusts the position of the moving plate 8 on the feed plate 4 back and forth to fit the fabric length, and then tightens the fasteners. After the operator places the fabric in the corresponding position, they press the first signal button 11 and the second signal button 15, activating the first and second cylinders. This drives the front pressure plate 10 to cooperate with the moving plate 8 to press the fabric, and the rear pressure plate 13 to cooperate with the feed plate 4 to press the fabric. After clamping the fabric at both ends, the laser positioning light 5 is used to inspect the buttonhole sewing position for any misalignment. If misalignment is found, the fabric is moved for adjustment.

[0049] The above embodiments are only one of the preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes made in accordance with the shape, structure and principle of this utility model should be covered within the protection scope of this utility model.
