DETAILED DESCRIPTION

[0021] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0022] Please refer to Figure 1 , Figure 2 and Figure 3 ,in Figure 1 A structural schematic diagram of a preferred embodiment of a sofa cover corner anti-deviation sewing device provided by the utility model; Figure 2 for Figure 1 The schematic diagram of the structure of the placement rack shown; Figure 3 for Figure 1 The structural schematic diagram of the partial cross-sectional view of the fixing platform shown in the figure, a sofa cover edge corner anti-deviation sewing device, comprising: a fixing platform 1, an anti-deviation component 2 is arranged on the top of the fixing platform 1, and a fixing component 3 is arranged inside the anti-deviation component 2;

[0023] The anti-deviating assembly 2 includes a sliding groove 21 which is transversely opened on the top of the fixed platform 1. A sliding frame 22 is longitudinally arranged on the rear side of the top of the fixed platform 1. A positioning plate 23 is arranged inside the sliding frame 22 so as to slide forward and backward.

[0024] By moving the positioning plate 23 on the inner side of the sliding frame 22 forward and backward, the position of the sofa cover sewing position can be positioned, and the position of the sofa cover can be preliminarily prevented from deflecting.

[0025] The fixing assembly 3 includes a placement rack 31 that can slide left and right along the inner side of the sliding groove 21, and a sliding rod 32 is vertically slidably arranged on the top of the placement rack 31. The bottom end of the sliding rod 32 passes through the top of the placement rack 31 and extends to the inner side thereof, and a pressing plate 33 is fixedly arranged on the bottom end of the sliding rod 32.

[0026] When fixing the sofa cover, the handle 35 is pulled upward to drive the pressing plate 33 to move upward, and then the sofa cover is put in. After adjusting the position, the handle is released, and the pressing plate 33 is relatively fixed on the placement frame 31 under the action of the pressing spring 34, thereby fixing the sofa cover.

[0027] A slot 24 is provided at the top of the fixed table 1 and in front of the sliding slot 21. A rotating screw 25 is rotatably arranged on the inner side of the slot 24. A threaded block 26 is connected to the rotating screw 25 on the circumferential side surface thereof so as to be movable left and right along its length. The back side of the threaded block 26 is fixedly connected to the bottom of the front side of the placement rack 31.

[0028] The rotation of the output end of the driving motor 27 drives the rotating screw 25 to rotate, and then drives the threaded block 26 to move to one side on the rotating screw 25, and then drives the placement rack 31 and the fixed sofa cover to move to one side, and cooperates with the sewing of the sewing device body 4 to sew the corners of the sofa cover. Since it slides along the sliding groove 21, the deviation that may be caused by manual movement is avoided, and after completing the sewing of one corner of the sofa cover, the next corner of the sofa cover can be directly removed and fixed. After fixing, the driving motor 27 can be reversed to drive the sofa cover to move to the other side, thereby improving the use efficiency of the sewing device.

[0029] A driving motor 27 for driving the rotating screw 25 to rotate is arranged on the right side of the bottom of the fixed platform 1. The right end of the rotating screw 25 passes through the inner side of the slot 24 and extends to the right side of the fixed platform 1. The output end on the right side of the driving motor 27 is connected to the right end of the rotating screw 25 by a belt.

[0030] The anti-deviating assembly 2 further includes a scale 28 disposed on the right side of the sliding frame 22 , and a tension bolt 29 is slidably disposed on the inner side of the sliding frame 22 and on the inner side of the positioning plate 23 .

[0031] The scale 28 is scaled from the front of the sliding frame 22 to the stitching point of the stitching device body 4. When the positioning plate 23 moves forward, the positioning plate 23 will block part of the scale. When the front of the positioning plate 23 is at the bottom of the stitching point, the scale 28 displays 0. The position of the adjusted positioning plate 23 can be fixed by the tightening bolt 29.

[0032] The fixing assembly 3 also includes a pressing spring 34 arranged on the inner side of the placement frame 31 and located on the side of the sliding rod 32. A handle 35 is slidably provided on the top of the placement frame 31, and the bottom of the handle 35 is fixedly connected to the top of the pressing plate 33.

[0033] A suturing device body 4 is provided at the rear side of the top of the fixing table 1 and inside the sliding frame 22 .

[0034] The working principle of the sofa cover corner anti-deviation sewing device provided by the utility model is as follows:

[0035] Step 1: When in use, loosen the tension bolt 29, determine the position of the positioning plate 23 according to the scale value of the scale 28 according to actual needs, and after the adjustment is completed, fix the positioning plate 23 with the tension bolt 29. By fixing the positioning plate 23, the rear side of the corner of the sofa cover can be prevented from deflection to a certain extent;

[0036] The second step: lift the pressing plate 33 through the handle 35, and then put the sewing part of the corner of the sofa cover into the inner side of the placement rack 31. When the back side of the corner of the sofa cover is completely close to the front side of the positioning plate 23, release the handle 35. Under the action of the pressing spring 34, the pressing plate 33 fixes the sofa cover. Finally, the rotation of the output end of the driving motor 27 drives the rotation of the rotating screw rod 25, and then drives the threaded block 26 to move to one side on the rotating screw rod 25, and then drives the placement rack 31 and the fixed sofa cover to move to one side, and cooperates with the sewing equipment body 4 to complete the sewing.

[0037] Compared with the related art, the sofa cover corner anti-deviation sewing device provided by the utility model has the following beneficial effects:

[0038] The pressing plate 33 is lifted up by the handle 35, and then the seamed corners of the sofa cover are placed inside the placement rack 31. The handle 35 is released and the pressing plate 33 is used to fix the sofa cover under the action of the pressing spring 34. Finally, the rotation of the output end of the driving motor 27 drives the rotation of the rotating screw rod 25, and then drives the threaded block 26 to move to one side on the rotating screw rod 25. Since the placement rack 31 slides along the sliding groove 21, the rear side of the sofa cover is always located at the front side of the positioning plate 23, avoiding the deviation that may be caused by manual movement.

[0039] Finally, it should be pointed out that the above embodiments are only representative examples of the present utility model. Obviously, the present utility model is not limited to the above embodiments, and there are many variations. Any simple modification, equivalent changes and modifications made to the above embodiments based on the technical essence of the present utility model should be considered to belong to the protection scope of the present utility model.
