[0002] Currently, many office or home chairs often have sponges, cotton, or other soft materials stuffed inside the backrest to improve comfort. This requires sewing or other stitching techniques to close the opening, resulting in vertical or horizontal stitch lines, collectively known as standard lines. To improve the sturdiness and aesthetics of the chair back, these standard lines must be aligned horizontally or vertically.

[0003] In the existing technology, the standard line of chair back is usually aligned manually, which makes it difficult to ensure that the standard line can be aligned. Moreover, multiple people are needed to complete the sewing work. Therefore, a simple chair back standard line alignment auxiliary device is needed. Utility Model Content

[0014] The beneficial effects of this utility model are:

[0015] 1. This simple chair back standard line alignment auxiliary device works by moving the rear clamping plate to the inside of the sewing area when the chair back needs to be sewn, and then activating the clamping cylinder. The clamping cylinder moves the clamping plate to the L-shaped plate, thereby fixing the sewing fabric with the cooperation of the clamping plate and the L-shaped plate. Then, the drive motor is activated, and the output shaft of the drive motor rotates to rotate the bidirectional screw. The rotation of the bidirectional screw brings the two sets of threaded blocks closer together, so that the sewing fabric can be sewn together after they are close together, eliminating the need for manual holding and fixing operations and reducing the sewing cost.

[0016] 2. This simple chair back standard line alignment auxiliary device, by activating the lifting cylinder during the sewing process, causes the output end of the lifting cylinder to retract, moving the mounting frame upward. This allows the L-shaped plate and the clamping plate to move upward while providing space for fabric sewing, enabling the standard line to be aligned and improving the processing efficiency of the chair back standard line.

Detailed Implementation

[0024] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0025] Example: Figures 1-5 As shown, this utility model provides a simple chair back standard line alignment auxiliary device, which includes a mounting plate 1 and an auxiliary alignment mechanism 2 provided on the rear side of the mounting plate 1.

[0026] The auxiliary alignment mechanism 2 includes a mounting frame 6. Inside the mounting frame 6, there are bidirectional screws 9 and threaded blocks 10. With the cooperation of the bidirectional screws 9 and threaded blocks 10, the sewn fabrics can be brought closer together. The bidirectional screws 9 are rotatably connected to the middle of the inner side of the mounting frame 6. Threaded blocks 10 are threadedly connected to the left and right sides of the outer periphery of the bidirectional screws 9. L-shaped plates 11 are fixedly connected to the rear side walls of the threaded blocks 10. Clamping cylinders 12 are set in the middle of the side walls of the two sets of L-shaped plates 11 that are close to each other. The clamping cylinders 12 are set inside the L-shaped plates 11. During the operation of the clamping cylinders 12, they can drive the clamping plates 13 to move to one side of the L-shaped plates 11. The output end of the clamping cylinders 12 is fixedly connected to the clamping plates 13. Placement grooves 14 are set in the middle of the side walls of the clamping plates 13 and L-shaped plates 11 that are close to each other. Clamping rollers 15 are rotatably connected to the inner side of the placement grooves 14. The clamping rollers 15 are set so that the L-shaped plates 11 and clamping plates 13 can move up and down to adjust the clamping position while maintaining the clamping state.

[0027] All clamps 13 are located on the inner rear side of the L-shaped plate 11. A stitching groove 4 is provided in the middle of the mounting plate 1. The mounting frame 6 is slidably connected to the inner side of the mounting groove 3. The mounting groove 3 is located in the middle of the rear wall of the mounting plate 1. The mounting groove 3 provides space for the installation of the mounting frame 6 and the lifting cylinder 5.

[0028] A lifting cylinder 5 is fixedly connected to the middle of the top wall of the sewing groove 4. The output end of the lifting cylinder 5 is fixedly connected to the middle of the top wall of the mounting frame 6. Multiple sets of evenly distributed control buttons 16 are provided in the middle of the top wall of the mounting plate 1. A handle 17 is fixedly connected to the outer side of the top of the mounting plate 1. Pressing the control button 16 can control the lifting cylinder 5, the clamping cylinder 12 and the drive motor 8 respectively.

[0029] A drive motor 8 is fixedly connected to the middle of the right side wall of the mounting frame 6. The output end of the drive motor 8 is fixedly connected to the bidirectional screw 9. A connecting groove 7 is provided in the middle of the right side wall of the mounting groove 3. The connecting groove 7 is clearance-fitted with the drive motor 8. The control buttons 16 are all located inside the handle 17. The control buttons 16 are electrically connected to the lifting cylinder 5, the clamping cylinder 12 and the drive motor 8 respectively. When the lifting cylinder 5 works, it causes the mounting frame 6 and its internal components to move up and down. When the drive motor 8 works, it can drive the bidirectional screw 9 to rotate. The clamping cylinder 12 can clamp and fix the fabric.

[0030] Working principle: When the chair back needs to be sewn, the rear clamping plate 13 is moved to the inside of the sewing area and the clamping cylinder 12 is activated. The clamping cylinder 12 moves the clamping plate 13 to the side of the L-shaped plate 11, thereby fixing the sewing fabric with the cooperation of the clamping plate 13 and the L-shaped plate 11. Then, the drive motor 8 is activated. The output shaft of the drive motor 8 rotates, causing the bidirectional screw 9 to rotate. The rotation of the bidirectional screw 9 causes the two sets of threaded blocks 10 to move closer to each other, so that the sewing fabric can be brought closer together for sewing, eliminating the need for manual holding and fixing. During the sewing process, the lifting cylinder 5 is activated. The output end of the lifting cylinder 5 retracts, causing the mounting frame 6 to move upward, thereby allowing the L-shaped plate 11 and the clamping plate 13 to move upward while providing space for sewing the fabric, so that the standard line can be aligned. Then, the aligned fabric can be sewn through the sewing groove 4.
