[0002] In the production of automotive curtain fabrics, long straight seams are frequently required, such as sewing long leather strips onto fabric.

[0003] In the prior art, long straight line sewing is generally done manually. When sewing, the material to be sewn needs to be pressed down so that the sewn material fits together smoothly for easy sewing. Currently, the position of the two pieces of fabric is generally aligned manually, and the fabric is pressed down by hand and slowly pushed forward during the sewing process. Manual operation has the following problems: 1) The placement error of the fabric is large, and it depends entirely on manual adjustment and visual inspection; 2) During the process of manually feeding the fabric forward, the manual operation error is large, and the slightest carelessness can easily cause the stitches to shift. At the same time, when manually aligning the position of the upper and lower layers of fabric, including the long leather strip and the fabric, there will also be a certain deviation, which can easily cause the two layers of material to be misaligned, resulting in a relatively high defective rate of the sewn product; 3) Manual sewing requires sewing one side before continuing to sew the other side. Not only is the manual operation cumbersome, but it is also not conducive to improving production efficiency. 4) Because the sewing thread is long, long-term work requires a high level of manual concentration. These problems undoubtedly have a great impact on product production efficiency, qualification rate, and cost. Utility Model Content

DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention.

[0031] Example 1, as Figure 1-8As shown, a double-sided automatic sewing workstation includes a workbench 1, an upper surface of the workbench 1 is provided with a strip slide 2 along the length direction of the workbench 1, and a first slide rail 3 is fixedly installed in the strip slide 2 along the length direction of the workbench 1. In this embodiment, two first slide rails 3 can be provided, and the two first slide rails 3 are arranged in parallel and spaced apart; a support plate 4 is slidably connected to the top of the first slide rail 3 through a slider; a material discharge platform 5 is fixedly installed above the support plate 4, and the material discharge platform 5 is rectangular, and the two long sides of the material discharge platform 5 are parallel to the length direction of the workbench 1. A drive motor 6 is fixedly installed at one end of the support plate 4, and a gear is fixedly installed on the output shaft of the drive motor 6, and a rack 7 is installed parallel to the inner side surface of one of the first slide rails 3, and the gear is meshed with the rack 7;

[0032] Two sewing workbenches 8 are provided in the middle of the workbench 1. The two sewing workbenches 8 are arranged at intervals along the width direction of the workbench 1. A sewing machine head assembly 11 and a leather strip feeding mechanism 12 are installed above each sewing workbench 8. The leather strip output end of the leather strip feeding mechanism 12 corresponds to the sewing end of the sewing machine head assembly 11; the sewing ends of the two sewing machine head assemblies 11 and the leather strip output ends of the two leather strip feeding mechanisms 12 respectively correspond to the two long sides of the discharge platform 5.

[0033] Working principle:

[0034] The working task is to sew on both sides of the cloth in a straight line direction and sew two long leather strips to the cloth at the same time. The long leather strips are input by two leather strip feeding mechanisms 12.

[0035] First, the fabric to be sewn is positioned by the positioning strip 104 and then laid on the material discharge platform 5 and pressed and fixed so that the areas to be sewn on the left and right sides of the fabric are exposed; then the drive motor 6 is controlled to operate, so that the gear on the output shaft of the drive motor 6 is engaged with the rack 7 to drive the entire supporting plate 4 to slide on the first slide rail 3 along the length direction of the workbench 1 from the starting point to the end point, and the starting point and end point are respectively located at the two ends of the length direction of the workbench 1.

[0036] When the starting position of the cloth area to be sewn on the discharge platform 5 corresponds to the output end of the leather strip of the leather strip feeding mechanism 12, the sewing machine head assemblies 11 and the leather strip feeding mechanism 12 on the left and right sides of the workbench 1 are controlled to operate, and the leather strip is conveyed through the leather strip feeding mechanism 12 so that the head end of the leather strip is located at the starting position of the cloth area to be sewn. At the same time, the two sewing machine head assemblies 11 are controlled to sew the areas to be sewn on both sides of the cloth respectively. During this process, the drive motor 6 operates synchronously to drive the discharge platform 5 to move at a uniform speed along the strip chute 2, and the first slide rail 3 is used to effectively ensure the straightness of the cloth during the conveying process. The sewing machine head assemblies 11 on the two sewing workbenches 8 operate synchronously, thereby achieving the effect of simultaneous sewing on both sides.

[0037] After sewing is completed, the discharge platform 5 is moved to the end position by the drive motor 6, and the sewn fabric is manually removed from the discharge platform 5; then the output shaft of the drive motor 6 is controlled to rotate in the opposite direction, and then the gear and rack 7 are engaged to drive the entire support plate 4 to return to the starting position along the first slide rail 3 to carry out sewing work on the next product.

[0038] In this embodiment, the sewing machine head assembly 11 adopts a well-known technical solution in the prior art, which is already understood by those skilled in the art and will not be described in detail here.

[0039] Example 2, as Figure 2 As shown in the figure, as a further preferred embodiment of the first embodiment, the workbench 1 includes a front loading platform 101 and a rear unloading platform 102. The rear end of the front loading platform 101 is connected to the front end of the rear unloading platform 102 via a connecting plate 103. Therefore, when not in use, the connecting plate 103 can be directly removed to separate the front loading platform 101 and the rear unloading platform 102 from each other, so that the entire device can be stored conveniently.

[0040] In the third embodiment, as a further preferred embodiment of the second embodiment, positioning bars 104 are fixedly mounted on both the left and right sides of the upper surface of the front loading platform 101. Thus, when the fabric to be sewn is laid on the unloading platform 5, the positioning bars 104 can be used to quickly position the fabric in the left and right longitudinal directions.

[0041] Example 4, as Figure 4-5 As shown, as a further preferred embodiment of the first embodiment, the discharge platform 5 includes a support plate 501 and a pressing frame 502. The support plate 501 is fixedly installed above the supporting plate 4. The front and rear ends of the support plate 501 are vertically installed with lifting slide modules 503. The sides of the lifting slide module 503 are slidably connected with sliding blocks 504. The sliding blocks 504 are respectively connected to the front and rear sides of the pressing frame 502. The pressing frame 502 is directly opposite to the support plate 501 up and down.

[0042] In the initial state, the pressing frame 502 is located above the support plate 501, with sufficient space between the pressing frame 502 and the support plate 501 for laying the fabric to be sewn. In use, the fabric to be sewn is first laid on the upper surface of the support plate 501 and aligned. After laying is completed, the lifting slide modules 503 are controlled to operate synchronously to drive the sliding block 504 to slide downward, thereby driving the pressing frame 502 to move downward. The pressing frame 502 is pressed against the upper surface of the support plate 501 to achieve a tight and fixed effect on the fabric to be sewn.

[0043] When sewing is completed, each lifting slide module 503 is controlled to operate in the reverse direction to drive the sliding block 504 to slide upward, and then drive the pressing frame 502 to move upward to the initial position, so that the staff can take out the sewn fabric on the support plate 501.

[0044] In this embodiment, the lifting slide module 503 adopts a well-known technical solution in the prior art, which is already understood by those skilled in the art and will not be described in detail here.

[0045] In the fifth embodiment, as a further preferred embodiment of the fourth embodiment, a plurality of pressing cylinders 505 are evenly mounted on the left and right edges of the upper surface of the pressing frame 502. The telescopic shafts of the pressing cylinders 505 pass through the pressing frame 502 and are fixedly connected to the pressing plates 506. Therefore, after the pressing frame 502 is driven downward to press the upper surface of the fabric to be sewn by the lifting slide module 503, the telescopic shafts of the pressing cylinders 505 can be controlled to extend, thereby driving the pressing plates 506 to move downward to press the upper edges of the fabric to be sewn, thereby further ensuring the stability of the fabric to be sewn during the sewing process.

[0046] In this embodiment, the pressing cylinder 505 adopts a well-known technical solution in the prior art, which is already understood by those skilled in the art and will not be described in detail here.

[0047] Example 6: Figure 6 As shown, as a further preferred embodiment of the first embodiment, a second slide rail 9 is fixedly installed above the sewing workbench 8 along the width direction of the workbench 1, and the length direction of the second slide rail 9 is perpendicular to the length direction of the first slide rail 3.

[0050] In this embodiment, the first guide wheel group 1204 includes a guide wheel A and a guide wheel B, wherein the end of the leather strip passes around the guide wheel A and the guide wheel B in sequence and then is connected to the second guide wheel group 1205. In addition, a rewinding cylinder can be provided above the guide wheel A, and the rewinding cylinder is fixedly mounted on the cross frame 1202. The telescopic shaft of the rewinding cylinder is connected to the driven wheel through the rotating shaft seat, and the outer circumference of the driven wheel cooperates with the outer circumference of the guide wheel A, so that when the leather strip passes around the guide wheel A, the pressure of the driven wheel can be used to ensure the stability of the leather strip during transportation. The guide wheel B can be installed on the output shaft of the output motor, and the output motor is fixedly mounted on the cross frame 1202, so that the guide wheel B is driven to rotate by the output shaft of the output motor, thereby realizing the transportation of the leather strip.
