Technical Field

[0001] The utility model relates to the field of sewing equipment, in particular to a device for assisting a sewing machine in sewing. Background Art

[0002] With the rapid development of the times, the types of shoes have become diversified, and the manufacturing process of the shoe body has also been continuously improved. In the existing shoe body manufacturing process, it is necessary to overlap two kinds of fabrics and sew them at the same time. Some finished shoe bodies need to have a through groove structure to adapt to various shoe shapes and meet the wearing needs of users.

[0003] In the existing shoe body manufacturing process, in order to ensure that the grooves of the two fabrics can be aligned as much as possible after overlapping to avoid the problem of groove deviation during stitching, bonding glue is usually brushed between the two fabrics before overlapping to increase the adhesion between the two fabrics, thereby making stitching more convenient. However, the glue brushing process is added before the sewing machine stitching, which reduces the efficiency of producing the finished product. Inaccurate control of the glue brushing time will cause glue to leak onto the fabric during stitching, and uneven glue brushing will also cause the fabric to shift during stitching, which can easily reduce the quality of the finished shoe body and even directly lead to the scrapping of the fabric.

DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] It should be noted that the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of the present utility model, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0029] like Figure 1 As shown, the utility model relates to a device for assisting a sewing machine in suturing. The device is used in conjunction with a sewing machine, and is particularly suitable for a computer sewing machine. The sewing machine usually has a needle 8 and a press table 9. The needle 8 is used for suturing and can automatically sew according to a computer-programmed route. The press table 9 is used in conjunction with the needle 8. The press table 9 is usually used to place fabric to be sewed. The press table 9 includes a movable and rotatable drum and a fixed cylindrical table. The drum is movably arranged on the cylindrical table. The device can assist in sewing fabrics such as shoe bodies, shoe tongues, etc. This embodiment takes the shoe body as an example.

[0030] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0031] Figure 1 The device for assisting a sewing machine with suturing according to one embodiment of the utility model is schematically shown. Figure 1 As shown, the auxiliary sewing device includes a pressing plate 1, an adapter 2, a first driving device 3, a second driving device 4 and a third driving device 5.

[0032] The pressing plate 1 is used to press the fabrics. In the present embodiment, the fabrics to be sewn to the shoe body include the first fabric 6 and the second fabric 7. The first fabric 6 and the second fabric 7 need to be placed on the pressing platform 9, wherein the first fabric 6 and the second fabric 7 have a through-hole structure. The first fabric 6 and the second fabric 7 overlap to form a notch 67. The notch 67 is a through elliptical structure, generally located in the middle of the shoe body. The pressing plate 1 can approach the pressing platform 9 and simultaneously press the overlapping first fabric 6 and the second fabric 7, and the pressing plate 1 can abut against the notch 67. Specifically, the middle part of the pressing plate 1 can press one of the fabrics and abut against the notch 67, which is used for positioning before sewing the shoe body to avoid the problem of the first fabric 6 and the second fabric 7 being offset during the sewing process.

[0033] like Figure 3As shown, the pressing plate 1 includes a pressing frame 11 and a pressing block 12. The middle part of the pressing frame 11 is in the shape of an elliptical square frame plate, and the interior is a hollow structure, which is used to press the cloth and is the main part that contacts the cloth. Pressing feet 111 are provided on both sides of the pressing frame 11. The pressing feet 111 adopt a stepped structure to avoid the pressing platform 9 to prevent interference. The pressing block 12 is arranged in the hollow part of the pressing frame 11, and is made of a plastic material that is softer than the pressing frame 11. Its shape is adapted to the pressing frame 11, and it is a roughly elliptical plate-like structure. The pressing block 12 can abut against the notch 67 to have a positioning effect. A suturing interval 1a is formed between the pressing frame 11 and the pressing block 12, specifically, the gap between the pressing frame 11 and the pressing block 12, which is the hollow part of the pressing plate 1. The edge of the notch 67 that needs to be sewed is exposed on the suturing interval 1a, so the needle 8 can sew on the suturing interval 1a, and sew the edge of the notch 67 to sew the first cloth 6 and the second cloth 7.

[0034] Furthermore, since the finished shape of the shoe body needs to have an arc, the press table 9 in this embodiment adopts a cylindrical shape, and the press table 9 has an arc-shaped placement surface 91. The first fabric 6 and the second fabric 7 can be placed on the placement surface 91 of the press table 9 after overlapping, so that the shoe body has a curved arc after the suturing operation is completed. Therefore, the pressing plate 1 has an arc shape that needs to be compatible with the surface of the press table 9, and the fabric can be bent into shape when the pressing plate 1 presses the fabric. Specifically, the outer shapes of the pressing frame 11 and the pressing block 12 both have a curved arc. The first fabric 6 and the second fabric 7 are pressed between the pressing plate 1 and the placement surface 91. During actual operation, the pressing cylinder of the press table 9 drives the first fabric 6 and the second fabric 7 to move on the cylindrical table of the press table 9, and then cooperates with the needle 8 to sew the line to form an outer shape with an arc shape. The arc structure of the pressing plate 1 and the placement surface 91 makes it easier for the finished shoe body to form an arc, and improves the efficiency of subsequent processing steps.

[0035] like Figure 4 As shown, the first driving device 3 is arranged on the rotating drum of the press table 9. In this embodiment, the first driving device 3 is arranged on the side of the press table 9, and is connected to the pressing plate 1 for driving the pressing plate 1 to move up and down, with the end pointing in the direction of gravity as the bottom. The output end of the first driving device 3 is connected to the presser foot 111 of the pressing frame 11, which can drive the pressing frame 11 to move downward and press the first cloth 6 and the second cloth 7 at the same time. It can be seen that the number of the first driving devices 3 in this embodiment is provided with two, which are arranged on both sides of the pressing plate 1, respectively, and can drive the pressing plate 1 to press the cloth downward. The first driving device 3 is preferably a cylinder, and can also be an oil cylinder, an electric telescopic rod, etc., as long as it can drive the pressing plate 1 to move up and down.

[0036] like Figure 4As shown, the second driving device 4 and the adapter 2 are arranged on the rotating cylinder of the press table 9. The second driving device 4 and the adapter 2 cooperate to enable the pressing block 12 to move up and down simultaneously with the pressing frame 11. Specifically, the second driving device 4 is preferably a cylinder, which is fixedly arranged on the press table 9 and located between the two first driving devices 3. The adapter 2 is drivingly connected to the second driving device 4, so that the adapter 2 is movably arranged on the press table 9, and the adapter 2 is connected to the pressing block 12 to drive the pressing block 12 to move up and down. In addition, the first driving device 3 and the second driving device 4 can output driving force at the same time, so that the pressing frame 11 and the pressing block 12 can move and reset at the same time.

[0037] The output end of the third driving device 5 is connected to the adapter 2, and is used to drive the adapter 2 to flip. Similarly, the third driving device 5 is movably arranged on the press table 9, and is driven by the second driving device 4 to move up and down to drive the adapter 2 to move. Specifically, in order to facilitate the second driving device 4 to drive the third driving device 5 and the adapter 2 at the same time, a connecting member 45 is provided between the third driving device 5 and the second driving device 4. The connecting member 45 adopts a bent plate structure. The third driving device 5 is arranged on the connecting member 45, and the output end of the second driving device 4 is drivingly connected to the connecting member 45 to drive the connecting member 45 to move. The third driving device 5 is preferably a motor, and can also be a cylinder, which is controlled by the program of the computer sewing machine.

[0038] Further, such as Figure 4 As shown, the adapter 2 is rotatably connected to the pressing block 12 (connected by a hinge structure), the third driving device 5 can drive the adapter 2 to flip on the pressing block 12, and the adapter 2 is provided with a bending portion 21, and the bending portion 21 adopts a "U"-shaped structure. In actual use, the third driving device 5 is located on the outside of the first fabric 6 and the second fabric 7, and the adapter 2 connected to the pressing block 12 has a portion that blocks the suture spacing 1a. During the routing of the needle 8, there is a suture segment that avoids the adapter 2, so that the final sewing route is incomplete. Therefore, in order to avoid the above-mentioned problem, the adapter 2 in this embodiment is flipped by its bending portion 21 to avoid the suture route, which effectively solves the above-mentioned problem. Specifically, before sewing, the needle 8 is positioned on the suture spacing 1a and is located in the bending portion 21. When the needle 8 is halfway through the suture routing, as shown in FIG. Figure 5 As shown, the third driving device 5 is controlled to output power to flip the adapter 2, thereby driving the bending portion 21 to flip. Therefore, the part of the bending portion 21 that blocks the suture spacing 1a before suturing is moved to the line segment where suturing is completed by flipping, and the originally blocked position of the bending portion 21 is exposed on the suture spacing 1a that has not yet been routed, so that the edge of the slot 67 is sutured and routed, so that the sutured line forms a complete closed loop.

[0039] It should be noted that the first drive device 3, the second drive device 4, and the third drive device 5 are the implementation parts for driving the moving components. In this embodiment, the air pump, control mechanism (switch) and control method thereof equipped with the above parts are well known to technicians in this field and will not be repeated here.

[0040] In other embodiments, the pressing block 12 is disposed in the pressing frame 11 and connected to the pressing frame 11, and the second driving device 4 can be omitted. For example, one end of the adapter 2 is rotatably connected to the pressing block 12, and the other end of the adapter 2 is rotatably connected to the pressing frame 11, and the third driving device 5 is disposed on the pressing block 12 or the pressing frame 11, so that the adapter 2 can be flipped, and the first driving device 3 can simultaneously drive the adapter 2 and the pressing plate 1 to move up and down, and can avoid the interference of the needle 8, thereby simplifying the driving structure. Alternatively, the adapter 2 can be directly set as a fixed structure, as long as it can connect the pressing frame 11 and the pressing block 12, and the normal suture routing process can also be carried out, which can be selected according to the actual use.

[0041] In some embodiments, an alignment mark (not shown) is provided on the arc-shaped placement surface 91 on the press table 9, and the alignment mark is exposed on the notch 67. When the first cloth 6 and the second cloth 7 are placed on the press table 9, the position of the notch 67 can be manually adjusted by the alignment mark, so that the pressing block 12 can be more accurately abutted against the notch 67 when pressed down, ensuring that the routing position of the needle 8 is more accurate. The alignment mark can be a notch, scale, mark, etc. on the press table 9, which can be easily identified.

[0042] Working principle: firstly, overlap the first fabric 6 and the second fabric 7 on the press table 9 to form a notch 67 after overlapping, and control the first drive device 3 and the second drive device 4 to output driving force at the same time so that the press frame 11, the press block 12 and the third drive device 5 move downward at the same time, so that the press plate 1 simultaneously presses the first fabric 6 and the second fabric 7, and the press block 12 abuts against the notch 67, and the edge of the notch 67 is exposed on the suture spacing 1a, the needle 8 is first positioned in the bending portion 21 of the adapter 2, and the needle 8 starts to suture and traverse, and the computer sewing machine controls the movement of the press table 9. When nearly half of the traverse process is passed, as shown in FIG. Figure 5 As shown, at this time, the needle 8 is located at the relative position of the initial position, and the needle 8 and the adapter 2 will not interfere with each other. Then the third driving device 5 is controlled to output a driving force, so that the bending portion 21 is flipped to the stitched line segment, and the part of the stitching interval 1a blocked by the initial position of the bending portion 21 is exposed again. In this process, the needle 8 does not stop moving. Figure 6 As shown, the stitching is continued to the initial position to complete the closed stitching, and finally the first driving device 3 and the second driving device 4 are controlled simultaneously to reset the pressing frame 11 and the pressing block 12, and the shoe body can be taken out.

[0043] The above description is only a preferred embodiment of the present invention. In order to make the description concise, not all possible combinations of the various technical features in the above embodiments are described. This does not limit the present invention in any form. Therefore, any modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the technical solution of the present invention are still within the scope of the technical solution of the present invention.
