DETAILED DESCRIPTION

[0029] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0030] It should be noted that the following detailed descriptions are illustrative and are intended to provide further explanation of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present application belongs.

[0031] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" may include both "above" and "below". The device may also be positioned in other different ways, rotated 90 degrees or in other orientations, and the spatially relative descriptions used herein are interpreted accordingly.

[0032] like Figures 1 to 6 As shown, the hook wire feeder assembly of the first embodiment includes: a wire feeder 10, a hook wire device 20 and a driving structure 30. The wire feeder 10 has a first wire feeding portion 121 and a second wire feeding portion 122. The hook wire device 20 has a hook wire portion 22, and the hook wire portion 22 cooperates with the second wire feeding portion 122. The wire feeder 10 and the hook wire device 20 are both arranged on the driving structure 30.

[0033] The technical solution of the first application example is used, and the first sewing thread cooperates with the first thread feeding part 121, and the second sewing thread cooperates with the second thread feeding part 122. The thread hook 20 cooperates with the second sewing thread, so that the first sewing thread and the second sewing thread are used to sew the items to be sewn. The above structure does not require the installation of sewing thread spools on the thread hook and feeder assembly, which can ensure that the first sewing thread and the second sewing thread are within a controllable range, and will not cause the unsightly sewing items due to the uncontrollable sewing threads during the sewing process. The technical solution of the present application effectively solves the problem in the prior art that when the sewing machine shuttle is sewing clothes, the sewing object becomes unsightly due to the replacement of the sewing thread.

[0034] It should be noted that the uncontrollable sewing thread mentioned above refers to the second sewing thread being used up and the need to replace the second sewing thread spool, which results in obvious unsightly problems such as overlapping or intermittent sewing of the sewing thread on the sewn article. In addition, in this embodiment, the driving structure 30 drives the thread feeder 10 and the thread hook 20 to rotate, so that the first sewing thread and the second sewing thread sew the sewn article.

[0035] In the technical solution of the first embodiment, the driving structure 30 includes a driving shaft 31, and the wire feeder 10 and the wire hooker 20 are both arranged on the driving shaft 31. The above structure is compact and easy to operate. By rotating the driving shaft 31, the wire feeder 10 and the wire hooker 20 are driven to rotate and cooperate. The first wire feeding part 121 hooks the first sewing thread on the needle of the sewing machine body, the second wire feeding part 122 hooks the second sewing thread, and the wire hooker 22 hooks the second sewing thread on the second wire feeding part 122.

[0036] like Figure 2As shown, in the technical solution of embodiment 1, the wire feeder assembly also includes a reverse structure 40, the wire feeder 10 is directly arranged on the drive shaft 31, and the wire hooker 20 cooperates with the drive shaft 31 through the reverse structure 40. The reverse structure 40 can realize that the rotation directions of the wire feeder 10 and the wire hooker 20 are opposite. For example, the wire feeder 10 is arranged at the first end of the drive shaft 31, the wire hooker 20 is arranged between the first end of the drive shaft 31 and the second end of the drive shaft 31, and the output end of the drive motor 32 is connected to the second end of the drive shaft 31. As other embodiments, the wire feeder 10 cooperates with the drive shaft 31 through the reverse structure 40, and the wire hooker 20 is directly arranged on the drive shaft 31. When the wire feeder 10 cooperates with the drive shaft 31 through the reverse structure 40, the wire feeder 10 also includes a wire feed seat 11, the first wire feed part 121 and the second wire feed part 122 are both arranged on the wire feed seat 11, the wire feed seat 11 has a second through hole, the inner wall of the wire feed seat 11 has a second internal gear, the drive shaft 31 passes through the second through hole, and the second gear 42 is arranged between the first gear 41 and the second internal gear. In the first embodiment, only one drive motor 32 is required, and the transmission ratio of the reverse structure 40 is set so that the second wire feed part 122 and the hooking part 22 cooperate.

[0037] like Figure 1 and Figure 2 As shown, in the technical solution of embodiment 1, the reverse structure 40 includes a first gear 41 and a second gear 42, and the first gear 41 is mounted on the drive shaft 31. The gear transmission method is adopted, which is relatively stable. When the wire hook 20 cooperates with the drive shaft 31 through the reverse structure 40, the wire hook 20 also includes a wire hook seat 21, and the wire hook portion 22 is arranged on the wire hook seat 21. The wire hook seat 21 has a first perforation, and the inner wall of the wire hook seat 21 has a first internal gear. The drive shaft 31 passes through the first perforation, and the second gear 42 is arranged between the first gear 41 and the first internal gear. The above structure is compact and the transmission is stable. It should be noted that in this embodiment, the second gear 42 is set to multiple, so that the force of the wire hook 20 is more balanced, the rotation is more stable, and the rotation accuracy is higher, and the output end of the drive motor 32 is connected to the drive shaft. It is also possible for the second gear 42 to be a gear set composed of multiple gears.

[0038] like Figure 3 and Figure 4 As shown, in the technical solution of the first embodiment, the second wire feeding portion 122 is arranged on one side of the arc-shaped protrusion of the first wire feeding portion 121, and the tip of the second wire feeding portion 122 is at a predetermined distance from the tip of the first wire feeding portion 121. The above structure is compact and saves materials, and the second wire feeding portion 122 does not need to be arranged on the wire feeding seat 11.

[0039] like Figures 3 to 5As shown, the wire feeder of the first embodiment includes: a wire feeding seat 11 and a wire feeding structure 12. The wire feeding structure 12 is connected to the wire feeding seat 11, and the wire feeding structure 12 has a first wire feeding part 121 and a second wire feeding part 122, and an end of the first wire feeding part 121 away from the wire feeding seat 11 and an end of the second wire feeding part 122 away from the wire feeding seat 11 have a predetermined distance.

[0040] By applying the technical solution of this embodiment, the first sewing line cooperates with the first thread feeding part 121, and the second sewing line cooperates with the second thread feeding part 122. The end of the first thread feeding part 121 away from the thread feeding seat has a predetermined distance from the end of the second thread feeding part 122 away from the thread feeding seat 11, so that when the first thread feeding part 121 cooperates with the first sewing line, the second thread feeding part 122 will not interfere; when the second thread feeding part 122 cooperates with the second sewing line, the first thread feeding part 121 will not interfere. The above structure does not require the installation of sewing lines on the thread feeder 10, so that the sewing lines can be ensured to be within a controllable range, and will not cause the problem of unqualified sewn items due to the uncontrollable sewing lines during the sewing process. The technical solution of this embodiment effectively solves the problem of unsightly sewn items caused by replacing the sewing lines when sewing clothes in the prior art sewing machine shuttle.

[0041] It should be noted that the wire feeder 10 of the present embodiment needs to be used in conjunction with the wire hooker 20 , and the specific structure and the method of cooperation of the wire hooker 20 are described in detail below.

[0042] like Figure 3 and Figure 4 As shown, in the technical solution of this embodiment, the first end of the first wire feeding part 121 is connected to the wire feeding seat 11, the first end of the second wire feeding part 122 is connected to the first wire feeding part 121, and the second wire feeding part 122 is located on the side of the first wire feeding part 121 away from the wire feeding seat 11. Such a structure ensures that the distance between the first wire feeding part 121 and the second wire feeding part 122 is set reasonably on the one hand, and on the other hand, the groove formed by the first wire feeding part 121 and the second wire feeding part 122 can form a good constraint on the sewing line (the sewing line refers to the first sewing line and the second sewing line), specifically, the second sewing line.

[0043] It should be noted that the first wire feeding portion 121 and the second wire feeding portion 122 have the same rotation direction, that is, the first wire feeding portion 121 and the second wire feeding portion 122 have the same extending direction.

[0044] like Figure 3 and Figure 4As shown, in the technical solution of this embodiment, in the projection in the direction parallel to the axis of the wire feeder, the first end of the second wire feeder 122 and the second end of the second wire feeder 122 are both located between the first end of the first wire feeder 121 and the second end of the first wire feeder 121. Such a structure allows the first sewing line to be avoided and then the second sewing line of the second wire feeder 122 can be used to perform the next cycle of sewing under the action of the thread hook 20. It should be noted that in the present application, the end of the first wire feeder 121 away from the wire feeder seat 11 corresponds to the second end of the first wire feeder 121, and the end of the second wire feeder 122 away from the wire feeder seat 11 corresponds to the second end of the first wire feeder 121.

[0045] like Figures 3 to 5 As shown, in the technical solution of this embodiment, the end of the first wire feeding portion 121 away from the wire feeding seat 11 has a pointed tip, and the cross-sectional area of ​​the first wire feeding portion 121 from the end away from the wire feeding seat 11 to the end close to the wire feeding seat 11 at least partially gradually increases. The second end of the first wire feeding portion 121 is a pointed tip, and such a structure is easy to cooperate with the first sewing thread. The cross-sectional area of ​​the first wire feeding portion 121 from the end away from the wire feeding seat 11 to the end close to the wire feeding seat 11 at least partially gradually increases, and such a structure enables the first sewing thread to have enough space to pass through the second wire feeding portion 122 under the action of the first wire feeding portion 121, and the second wire feeding portion 122 can send the second sewing thread to a suitable position to cooperate with the first sewing thread.

[0046] like Figure 4 As shown, in the technical solution of the present embodiment, the side of the first wire feeding portion 121 facing the wire feeding seat 11 is an arc or an arc surface. The first wire feeding portion 121 applies a force to the first sewing line on the side facing the wire feeding seat 11, and the side of the first wire feeding portion 121 facing the wire feeding seat 11 is an arc or an arc surface, so that the force and running trajectory of the first wire feeding portion 121 on the first sewing line are a gradual transition, and it is not easy to have a sudden change in the force and running trajectory, that is, the first sewing line is more stable. It should be noted that the side of the first wire feeding portion 121 facing the wire feeding seat 11 is a gradual arc or a gradual arc surface. In the direction from the second end of the first wire feeding portion 121 to the first end of the first wire feeding portion 121, the slope of the first wire feeding portion 121 on the side of the wire feeding seat 11 gradually increases (the above slope may have some slight mutations).

[0047] like Figure 4As shown, in the technical solution of this embodiment, the second wire feeding portion 122 has a pointed end away from the first wire feeding portion 121, and the cross-sectional area of ​​the second wire feeding portion 122 from the end away from the first wire feeding portion 121 to the end close to the first wire feeding portion 121 gradually increases at least in part. The second wire feeding portion 122 has a pointed end away from the first wire feeding portion 121, and such a structure makes it easy for the second wire feeding portion 122 to cooperate with the second sewing thread, and then when the second sewing thread gradually increases in the second wire feeding portion 122, the second sewing thread is easy to cooperate with the thread hook 20. In the direction from the second end of the second wire feeding portion 122 to the first end of the second wire feeding portion 122, the slope of the second wire feeding portion 122 toward the side of the first wire feeding portion 121 increases (the above slope may have some slight mutations).

[0048] It should be noted that the wire feeding structure 12 is plate-shaped, and the first end of the plate-shaped wire feeding structure 12 is connected to the wire feeding seat 11, and the second end of the plate-shaped wire feeding structure 12 forms two tips, namely the tip of the first wire feeding part 121 and the tip of the second wire feeding part 122, and there is a groove between the tip of the first wire feeding part 121 and the tip of the second wire feeding part 122.

[0049] like Figure 4 As shown, in the technical solution of this embodiment, the side of the second thread feeding part 122 facing the first thread feeding part 121 is an arc or an arc surface, and the side of the first thread feeding part 121 facing the second thread feeding part 122 is an arc or an arc surface. In this way, the operation of the second sewing line is more stable. As another embodiment, the side of the second thread feeding part 122 facing the first thread feeding part 121 is an arc or an arc surface.

[0050] like Figures 1 to 5 As shown, in the technical solution of the present embodiment, the wire feeding seat 11 includes a mounting portion 111 and a connecting portion 112, the mounting portion 111 is connected to the connecting portion 112, the mounting portion 111 is connected to the driving structure 30, and the wire feeding structure 12 is arranged on the connecting portion 112. The mounting portion 111 is connected to the driving structure 30, so that the setting of the connecting portion 112 is more flexible and is not easy to interfere with the setting of the wire feeding structure 12. The connecting portion 112 is connected to the wire feeding structure 12. It should be noted that the mounting portion 111, the connecting portion 112 and the wire feeding structure 12 are an integral structure. In the present embodiment, the mounting portion 111 is a cylindrical structure, the driving structure 30 extends into the middle mounting hole of the mounting portion 111, and the driving structure 30 is connected to the mounting portion 111 by a top screw, and as another connection method, it can also be an interference connection. The connecting portion 112 is a circular plate-shaped structure, and the mounting portion 111 and the wire feeding structure 12 are respectively located on both sides of the connecting portion 112.

[0051] like Figure 1 , Figure 2 and Figure 6As shown, the thread hook 20 cooperates with the thread feeder 10, the thread feeder 10 is the above-mentioned thread feeder 10, and the thread hook 20 includes: a thread hook seat 21 and a thread hook portion 22. The first end of the thread hook portion 22 is connected to the thread hook seat 21. The thread hook portion 22 can hook the second sewing thread of the second thread feeding portion 122 on the thread feeder 10, so that the second sewing thread is separated from the second thread feeding portion 122, and prepares for the second thread feeding portion 122 to cooperate with the second sewing thread.

[0052] like Figure 6 As shown, in the technical solution of this embodiment, the cross-sectional area of ​​the thread hooking portion 22 is at least partially gradually increased in the direction from the second end of the thread hooking portion 22 to the first end of the thread hooking portion 22. The second end of the thread hooking portion 22 is a pointed end, which is convenient for hooking the thread, that is, hooking the second sewing line, more accurately.

[0053] like Figure 6 As shown, in the technical solution of this embodiment, the side of the thread hooking portion 22 facing the thread hooking seat 21 is an arc surface or an arc line, and in the direction from the second end of the thread hooking portion 22 to the first end of the thread hooking portion 22, the slope of the thread hooking portion 22 on the side facing the thread hooking seat 21 gradually increases. The side of the thread hooking portion 22 facing the thread hooking seat 21 is an arc surface or an arc line, so that the thread hook 20 is relatively smooth when cooperating with the second sewing thread. The slope of the thread hooking portion 22 on the side facing the thread hooking seat 21 gradually increases, so that the movement effect of the second sewing thread is better. It should be noted that the above-mentioned slope of the thread hooking portion 22 on the side facing the thread hooking seat 21 gradually increases to the main part of the thread hooking portion 22. In order to achieve a better thread hooking effect, the end of the second end of the thread hooking portion 22 may have some mutations.

[0054] like Figure 1 and Figure 2 As shown, the embodiment of the present application uses the wire feeder 10 to feed the wire, and the hooking device 20 cooperates with the wire feeder 10 to hook the sewing thread on the wire feeder 10 or feed it to the wire feeder 10, so that the first sewing thread and the second sewing thread are sewn together. The hooking wire feeder assembly replaces the existing rotary hook function, and there is no need to set a sewing thread spool on the hooking wire feeder assembly, which effectively avoids the unqualified sewing product caused by the use of the sewing thread.

[0055] like Figure 7As shown, the difference between the technical solution of the second embodiment and the technical solution of the first embodiment is that the reverse structure 40 includes an active member 43, a first follower 44 and a second follower 45, the first follower 44 and the wire feeder 10 are connected to the drive shaft 31, the second follower 45 is connected to the wire hook 20, the second follower 45 is rotatably sleeved on the drive shaft 31, and the active member 43 cooperates with the first follower 44 and the second follower 45. The above structure only needs to set up one drive motor 32, which can save costs and is easy to control. The first follower 44 and the second follower 45 are set to the same structure, which can achieve the same rotation period of the wire feeder 10 and the wire hook 20.

[0056] like Figure 7 As shown, in the technical solution of the second embodiment, the first follower 44 includes a first plate 441, a second plate 442 and a plurality of first connecting rods 443, the axis of the driving shaft 31 is perpendicular to the first plate 441 and the second plate 442, and the plurality of first connecting rods 443 are evenly spaced between the first plate 441 and the second plate 442, the second follower 45 includes a third plate 451, a fourth plate 452 and a plurality of second connecting rods 453, the third plate 451 and the fourth plate 452 are parallel to the first plate 441, and the plurality of second connecting rods 453 are evenly spaced between the third plate 451 and the fourth plate 452, the active member 43 includes a fifth plate 431 and a plurality of shifting rods 432, and the plurality of shifting rods 432 are evenly spaced on the fifth plate 431. The above structure can be flexibly arranged according to the space. It should be noted that the output end of the driving motor is connected to the fifth plate 431. The connecting rod mentioned above may also be a gear structure or other structures, all of which are within the protection scope of the present application.

[0057] like Figure 8 As shown, in the technical solution of the third embodiment, the driving shaft 31 includes a first driving shaft and a second driving shaft, the wire feeder 10 is arranged on the first driving shaft, the wire hooker 20 is arranged on the second driving shaft, and the wire feeder 10 and the wire hooker 20 are arranged opposite to each other. This embodiment is controlled by setting two independent driving motors 32, and such a structural design is convenient, and there is no need to set a separate reverse structure 40, which has relatively low requirements for designers.

[0058] The present application also provides a sewing machine, comprising a sewing machine body and a hook feeder assembly arranged on the sewing machine body, wherein the hook feeder assembly is the above-mentioned hook feeder assembly. The driving structure 30 is movably mounted on the sewing machine body, so that it is convenient to adjust the positional relationship between the wire feeder 10 and the hook thread device 20, and it is also convenient to adjust the positional relationship between the hook feeder assembly and the machine needle of the sewing machine body.
