[0031] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application.

[0032] As Figures 1-4As shown, the auxiliary fastening device of the sewing machine in this embodiment of the invention includes: a frame 1, a rotating component 2, and a reciprocating component 3.

[0033] The frame 1 is used for mounting on the needle plate 100 of the sewing machine. The rotating assembly 2 is connected to the frame 1 and includes a rotating member 21, at least a portion of which rotates about a first axial direction (i.e., as shown in the image). Figure 1 The reciprocating assembly 3 is rotatable in the up-down direction. The reciprocating assembly 3 is connected to the rotating part 21 so that the rotating part 21 rotates and drives the reciprocating assembly 3 to rotate. The reciprocating assembly 3 includes a reciprocating part 31. The reciprocating assembly 3 is movable between a first position and a second position. In the first position, the first end of the reciprocating part 31 (i.e., the lower end of the reciprocating part 31) is radially spaced from the needle plate 100 of the sewing machine so that the fabric 300 is placed between the reciprocating part 31 and the needle plate 100 of the sewing machine. In the second position, the first end of the reciprocating part 31 inserts the fabric 300 onto the sealing needle 200 of the needle plate 100.

[0034] It is understandable that, as shown in the figure, the frame 1 and the needle plate 100 of the sewing machine can be connected by plugging or snapping to facilitate the assembly and disassembly of the frame 1. At least a portion of the rotating component 21 can be connected to a motor to achieve rotation about a first axis.

[0035] Specifically, such as Figure 1 As shown, the reciprocating component 31 is movable in the left-right direction, meaning that the second position is closer to the turntable of the sewing machine than the first position. The reciprocating component 31 can also be driven by a telescopic motor or a drive device with linear reciprocating function (such as a gear and rack device driven by a motor).

[0036] In other words, the worker only needs to place the fabric 300 between the reciprocating part 31 and the needle plate 100 of the sewing machine, drive the reciprocating part 31 to move from the first position to the second position, thereby inserting the fabric 300 onto the sealing needle 200 of the needle plate 100. Then, the worker moves the reciprocating part 31 from the second position to the first position, starts the rotating part 21 and rotates it in one direction (clockwise or counterclockwise) by a certain angle, and repeats the movement of the reciprocating part 31 between the first and second positions, thereby inserting the fabric 300 onto the needle plate 100 along the circumference of the needle plate 100 of the sewing machine.

[0037] In other words, the auxiliary buckle device of the sewing machine in this embodiment of the invention can first allow the worker to place the fabric 300, cloth, etc. between the reciprocating part 31 and the needle plate 100 of the sewing machine, and then move the reciprocating part 31 from the first position to the second position, thereby inserting the fabric 300 onto the sealing needle 200 of the needle plate 100, avoiding close contact between the worker's hand and the sealing needle 200 of the needle plate 100, and reducing the possibility of the worker being pricked.

[0038] Therefore, the auxiliary buttoning device of the sewing machine can conveniently push the cloth into the needle disc 100, reduce the possibility of workers being stabbed, and improve the production efficiency.

[0039] Optionally, the rotating assembly 2 further comprises a first driving member 22, the rotating member 21 comprises a fixed part 211 and a rotating part 212, the fixed part 211 is connected with the rack 1, and the first driving member 22 is connected with the rotating part 212, so as to drive the rotating part 212 to rotate around the first axis.

[0040] Specifically, as shown in the figure, Figure 1 the fixed part 211 is detachably connected with the rack 1 through bolts or screws, and the rotating part 212 is rotatable relative to the fixed part 211.

[0041] It can be understood that the rotating member 21 is a bearing, that is, the fixed part 211 is an outer ring of the bearing, and the rotating part 212 is an inner ring of the bearing. Optionally, the first driving member 22 can be a steering engine, a stepping motor, a brushless motor, etc. The output shaft of the first driving member 22 is connected with the rotating part 212 through a shaft coupling, so as to drive the rotating part 212 to rotate, thereby driving the reciprocating assembly 3 to rotate.

[0042] Optionally, the rack 1 comprises a base 11, a first mounting frame 12 and a second mounting frame 13, the first mounting frame 12 and the second mounting frame 13 are both connected with the base 11, the base 11 is connected with the needle disc 100 of the sewing machine, the first driving member 22 is connected with the first mounting frame 12, and the fixed part 211 is connected with the second mounting frame 13.

[0043] Specifically, as shown in the figure, Figure 1 the first mounting frame 12 and the second mounting frame 13 are connected with the base 11 through a rigid column 14, that is, the first mounting frame 12 and the second mounting frame 13 are both circular rings, and mounting openings are arranged on the first mounting frame 12 and the second mounting frame 13, the contour of the mounting opening is matched with the contour of the outer circumferential surface of the rigid column 14, so that after the rigid column 14 is connected with the base 11 through bolts, the first mounting frame 12 and the second mounting frame 13 are sleeved on the rigid column 14 through the mounting openings.

[0044] It can be understood that, as shown in the figure, Figure 1 the first mounting frame 12 and the second mounting frame 13 are arranged in sequence along the up-down direction, and the first mounting frame 12 is located below the second mounting frame 13. Taking the rotating member 21 as a bearing for example, the second mounting frame 13 is two, and the two second mounting frames are arranged in a stacked manner on the upper and lower sides of the fixed part 211, and the rotating part 212 of the rotating member 21 is located at the middle position of the second mounting frames, so as to be connected with the output shaft of the first driving member 22. The two second mounting frames fix the fixed part 211 through bolts.

[0045] That is, the first driving member 22 and the rotating member 21 are respectively installed on the first mounting frame 12 and the second mounting frame 13, and the first mounting frame 12 and the second mounting frame 13 are detachably connected with the base 11, so that the rotating assembly 2 and the reciprocating assembly 3 are conveniently detached from the base 11.

[0046] In other words, since there are different models of the sewing disc machine, the specifications of the needle disc on the different models of the sewing disc machine are also different, and more specifically, the size and the height of the needle disc are different. Therefore, the auxiliary buttoning device of the sewing disc machine according to the embodiment of the present application can select a suitable base 11 according to the needle disc 100 of the sewing disc machine of different specifications. Since the rotating assembly 2 and the reciprocating assembly 3 are connected with the base 11 through the first mounting frame 12 and the second mounting frame 13, after selecting a new base 11, the first mounting frame 12 and the second mounting frame 13 on the original base 11 are removed and then mounted on the new base 11, so that the auxiliary buttoning device of the sewing disc machine according to the embodiment of the present application can be used on the needle disc 100 of the sewing disc machine of different specifications. In addition, after mounting the base 11, the height of the push handle 312 can be adjusted by using the adjusting member 33, so that the middle position of the push handle 312 is at the same height as the sewing disc needle on the needle disc. Therefore, the auxiliary buttoning device of the sewing disc machine according to the embodiment of the present application also has the advantage of wide application range.

[0047] Optionally, the base 11 has an annular groove 111, which is located on the side of the base 11 adjacent to the needle disc 100 of the sewing disc machine, and the annular groove 111 is matched with the annular protrusion on the needle disc 100 of the sewing disc machine.

[0048] Specifically, as shown in Figure 1 and Figure 2 , the annular groove 111 is formed on the lower bottom surface of the base 11, the base 11 is cylindrical, and the center line of the base 11 coincides with the center line of the annular groove 111. That is, by matching the annular groove 111 with the annular protrusion, the center alignment and connection and fixation of the base 11 and the needle disc 100 of the sewing disc machine can be achieved.

[0049] It can be understood that generally, the upper surface of the needle disc 100 of the sewing disc machine is provided with an annular protrusion, so that when the base 11 is matched with the needle disc 100 of the sewing disc machine, the annular protrusion can be matched in the annular groove 111, and adhesive can also be used for bonding, so as to improve the stability of the connection between the base 11 and the needle disc 100.

[0050] Preferably, at least one of the base 11 and the needle disc 100 of the sewing disc machine is provided with a magnetic member 15, and the base 11 and the needle disc 100 of the sewing disc machine are magnetically attracted.

[0051] It can be understood that, as Figure 2As shown, the base 11 may be equipped with a magnetic element 15, and the needle plate 100 of the sewing machine may be made of a magnetic material that can magnetically attract the magnetic element 15; or, the needle plate 100 of the sewing machine may be equipped with a magnetic element 15, and the base 11 may be made of a magnetic material that magnetically attracts the magnetic element 15; or both the needle plate 100 and the base 11 of the sewing machine may be equipped with magnetic elements 15, and the magnetic poles of the two magnetic elements 15 may be opposite. This allows the magnetic element 15 to further improve the alignment and connection between the center of the base 11 and the needle plate 100 after they are engaged.

[0052] Optionally, the reciprocating assembly 3 further includes a second drive member 32, which is connected to the second end (i.e. the upper end of the reciprocating member 31) of the reciprocating member 31 so as to drive the reciprocating member 31 to move between a first position and a second position.

[0053] It is understandable that the second drive component 32 can be a telescopic motor, in which case the output shaft of the second drive component 32 can be directly connected to the second end of the reciprocating component 31; or, the second drive component 32 can be a motor-driven linear reciprocating device, such as a motor-driven crank-connecting rod mechanism, gear and rack mechanism, cam mechanism, and worm gear, etc. This allows the activation of the second drive component 32 to drive the reciprocating component 31 to reciprocate in the left-right direction (i.e., to move the reciprocating component 31 between the first and second positions).

[0054] Optionally, the reciprocating assembly 3 further includes an adjusting member 33, which includes an adjusting body 331 and an adjusting part 332. The adjusting part 332 is connected to the adjusting body 331 and is movable relative to the adjusting body 331. The second driving member 32 is connected to the adjusting body 331, and the second end of the reciprocating member 31 is connected to the adjusting part 332 so as to adjust the position of the reciprocating member 31 in the height direction of the frame 1.

[0055] Specifically, such as Figure 1 As shown, the adjusting body 331 is provided with a mounting groove, which runs through the adjusting body 331 in the left-right direction. The adjusting part 332 runs through the adjusting body 331 in the up-down direction. The middle section of the adjusting part 332 is placed in the mounting groove. The second end of the reciprocating part 31 is connected to the middle section of the adjusting part 332 and placed in the mounting groove, so as to use the inner wall surface of the mounting groove to limit the back-and-forth swaying of the reciprocating part 31 and improve the stability of the reciprocating part 31.

[0056] It is understood that the adjusting part 332 is a lead screw, and the second end of the reciprocating part 31 is provided with a lead screw nut that matches the lead screw. The adjusting part 332 and the second end of the reciprocating part 31 cooperate to form a lead screw nut structure, so that when the adjusting part 332 is rotated, the reciprocating part 31 can be driven to move in the up and down direction, thereby realizing the adjustment of the height between the reciprocating part 31 and the needle plate 100.

[0057] Optionally, the reciprocating assembly 3 further comprises a stabilizing member 34 connected to the rotating portion 212, the second driving member 32 comprises a driving portion 321 and a connecting portion 322, the connecting portion 322 is connected between the driving portion 321 and the adjusting body 331, and at least part of the connecting portion 322 penetrates through the stabilizing member 34, and the connecting portion 322 is movable relative to the stabilizing member 34.

[0058] It can be understood that, as shown in Figure 1 The stabilizing member 34 is connected to the rotating portion 212 by a screw or a bolt. The connecting portion 322 is in a rod shape, and the connecting portion 322 is connected between the driving portion 321 and the adjusting body 331, so that the driving portion 321 drives the adjusting body 331 (i.e., the resetting member) to move through the connecting portion 322.

[0059] Specifically, as shown in Figure 1 The driving portion 321 and the connecting portion 322 are connected by two connecting rods, one end of the first connecting rod is connected to the output shaft of the driving portion 321, the other end of the first connecting rod is connected to one end of the second connecting rod, and the other end of the second connecting rod is connected to the connecting portion 322. Since the extension directions of the connecting rods and the connecting portion 322 are orthogonal to the extension direction of the output shaft of the driving portion 321, the driving portion 321, the connecting rods, and the connecting portion 322 constitute a “crank connecting rod mechanism”, and thus the driving portion 321 drives the reciprocating member 31 to realize reciprocating movement in the left-right direction.

[0060] It should be noted that the driving portion 321 of the second driving member 32 can be a stepper motor, a brushless motor, a servo motor, etc.

[0061] Optionally, the reciprocating member 31 comprises a reciprocating body 311 and a pushing hand portion 312, the reciprocating body 311 is connected between the pushing hand portion 312 and the adjusting portion 332, the pushing hand portion 312 is arranged adjacent to the needle disc 100 of the sewing machine, the pushing hand portion 312 is provided with a groove facing the needle disc 100 of the sewing machine and a pushing net covering the groove, and the needle disc 100 of the sewing machine is arranged in a spaced manner with the pushing net in a plane orthogonal to the height direction of the rack 1.

[0062] Optionally, the pushing net is made of a flexible material, and the pushing hand portion 312 is arc-shaped in the plane orthogonal to the height direction of the rack 1. That is, the pushing hand portion 312 is arc-shaped, which can increase the contact area of the pushing hand and the needle disc 100, and avoid the pushing hand intersecting with the needle disc 100 when the reciprocating member 31 is in the second position, so as to increase the deformation of the pushing net. That is, when the reciprocating member 31 is in the second position, the sewing machine needle on the needle disc 100 can be inserted into the groove, and since the circumferential wall of the needle disc 100 is arc-shaped, the pushing net will be deformed along the circumferential direction of the needle disc 100. Therefore, the pushing hand portion 312 is arc-shaped, which can better fit the needle disc 100, so that the pushing net can restore itself after deformation, and facilitate long-time work.

[0063] It should be noted that the push net can be a porous sponge, gauze, cashmere fabric, silk fabric, cotton silk fabric, etc.; the reciprocating body 311 can be made of resin material, PLA, ABS, polytetrafluoroethylene, etc.

[0064] That is, the push net is composed of flexible mesh material, which not only ensures damage-free contact with the fabric 300 during use, but also avoids the sewing disc machine needle on the needle disc when in the second position, thereby avoiding damage to the sewing disc machine needle and improving the service life of the auxiliary buttoning device of the sewing disc machine of the embodiment.

[0065] The use state of the auxiliary buttoning device of the sewing disc machine of the embodiment will be further described below. Figure 3 and Figure 4 The use state of the auxiliary buttoning device of the sewing disc machine of the embodiment will be further described below.

[0066] As shown in Figure 3 , when the push handle of the auxiliary buttoning device of the sewing disc machine of the embodiment is arranged at a distance from the needle disc 100, the reset member is in the first position, and the fabric 300 should be placed between the push handle and the needle disc 100. At this time, the position of the fabric 300 can be adjusted by the operator. After the position of the fabric 300 is determined, the second driving member 32 is started, and the reset member moves from the first position to the second position. The fabric 300 is pushed into the needle disc 100 by the push handle, and the reciprocating member 31 moves to the second position, i.e. Figure 4 , the push handle of the auxiliary buttoning device of the sewing disc machine of the embodiment completes a push-in action. Then the push handle is withdrawn from the needle disc 100 by the second driving member 32, i.e. the reset member moves from the second position to the first position. At this time, the fabric 300 will remain on the needle disc 100. The rotating assembly 2 is started again to rotate the auxiliary buttoning device of the sewing disc machine of the embodiment by a certain angle, and the push handle is repeatedly pushed in and pushed out, thereby realizing the winding of the fabric 300 on the needle disc 100.
