[0037] The wire needs to pass through the wire seat, and the wire passing component in the prior art is designed with many wire-free structures to achieve wire-free, for example, the wire passing component in the Chinese utility model patent with publication number CN 115233386 A includes a wire seat and a wire passing porcelain sleeve arranged in the middle of the wire seat. The middle of the wire seat is formed with a mounting hole for clamping the wire passing porcelain sleeve. The bottom of the wire passing porcelain sleeve is formed with a clamping block matching the size of the mounting hole. The top of the wire passing porcelain sleeve is formed with a bending structure. The bending structure and the clamping block form a wire passing hole therebetween. The faceplate is formed with a mounting position matching the wire seat. The mounting position is a groove formed on the surface of the faceplate. The size of the groove is consistent with the cross-sectional size of the wire seat, so that the wire seat is clamped on the mounting position. The adjacent mounting positions are formed with a spacing strip, so that the wire seat is individually stressed during use. The stress on the wire seat does not affect the adjacent wire seats. The wire seat and the mounting position of the faceplate are in interference fit, so that the wire seat transmits external force to the faceplate when stressed, ensuring the stability of the wire seat. The mounting hole is in rectangular structure. The clamping block is in corresponding rectangular structure. The clamping block and the mounting hole are in interference fit, realizing the fixed connection of the wire passing porcelain sleeve on the wire seat. The bending structure is arranged close to the wire seat, so that there is a gap between the bending structure and the wire seat. The gap facilitates the disengagement of the wire from the wire seat. The wire seat is provided with a wire protection spring arranged around the mounting hole. The wire seat is formed with a plug-in seat for plugging the end of the wire protection spring. The wire protection spring is in U-shaped structure. The wire seat is formed with a placing groove along the inner circle of the mounting hole. The wire protection spring is positioned vertically on the wire seat. The end of the wire protection spring is formed with two plug-in pieces. The wire seat is formed with a plug-in seat for plugging the two plug-in pieces, realizing the horizontal positioning of the wire protection spring and the stable connection of the wire protection spring on the wire seat. The wire protection spring is arranged around the wire passing porcelain sleeve. The middle of the wire protection spring is formed with an arc-shaped section corresponding to the bending structure. The arc-shaped section and the bending structure form a small gap, facilitating the manual disengagement of the wire from the wire passing component.

[0038] Due to the complex structure and many components, the cost is high. The present embodiment is to overcome this drawback. A wire passing component 200 is provided, which includes a row of wire seats 21 arranged in the transverse direction. The wire seat 21 includes transverse side walls and a rear bottom wall 213 connected to the rear ends of the two side walls. Here, the transverse side walls are located on the opposite sides of the wire seat 21, which are the first side wall 211 and the second side wall 212. In addition, the wire seat 21 is provided with an opening 214 between the front ends of the first side wall and the second side wall, so as to form an open groove structure on the wire seat 21.

[0039] The first side wall 211 is provided with a blocking line portion 217 extending to the second side wall 212, the second side wall 212 is provided with a groove 215, the head end of the blocking line portion 217 extends into the groove and is provided with a line gap 216 between the blocking line portion 217 and the groove 215. In this way, the line can be threaded from front to back without up and down threading, and since the head end of the blocking line portion extends into the groove, the line is not easy to come out of the line seat, so that the threading is facilitated and the line is prevented from coming out, and compared with the prior art, the line guard spring is not needed, the structure is simplified and the cost is reduced.

[0040] Specifically, the blocking line portion 217 extends from the front of the first side wall to the rear side wall of the groove in a slanting or arc shape, that is, is inclined or arc-shaped as a whole, so as to form a line guiding opening between the front side of the blocking line portion and the second side wall of the line seat, thereby facilitating the threading of the line, and the rear side of the blocking line portion is also inclined or arc-shaped, thereby forming a line passing groove with the first side wall 211, the second side wall 212 and the rear bottom wall 213, and the line passes through the line passing groove. Furthermore, the head end of the blocking line portion 217 is provided with an upper and lower gap between the upper and lower side walls of the groove and a front and rear gap between the rear side wall of the groove, the upper and lower gap and the front and rear gap cooperate to form the line gap, and the front and rear gap is larger than the upper and lower gap, thereby facilitating the threading of the line and preventing the line from coming out.

[0041] In addition, the head end of the blocking line portion 217 is provided with an arc-shaped wire guide surface for guiding the line into the line gap. The groove 215 extends transversely through the second side wall 212, and the head end of the blocking line portion is located at the transverse middle position of the groove 215. The edge of the opening of the groove 215 is provided with a circular arc chamfer.

[0042] Since a plurality of line seats 21 are arranged side by side, in order to facilitate the installation of the line seat, the line passing component further comprises a base plate 22, the line seat 21 is arranged on the base plate 22, and the base plates of the plurality of line seats are integrally arranged along the transverse direction, and the base plate is fixed to the panel. For example, the base plate is provided with a positioning groove, and the line seat 21 is positioned in the positioning groove and can be fixed by buckling or by screws.

[0043] In addition, in order to solve the problem of inconvenient adjustment of the threader spring nut adjusting structure in the prior art, the threader of the present embodiment is provided with a threader spring adjusting structure, which comprises a threader spring nut assembly 100 mounted on the panel 300. The threader spring nut assembly 100 is partially structured according to the prior art, and the threader spring nut assembly 100 comprises a threader spring 12, a threader spring screw rod 11 passing through the threader spring, and a threader spring nut 14 connected to the front end of the threader spring screw rod. The threader spring 12 is provided with a thread hook 122, and the line passes through the thread hook. During the threading process, the line pulls the thread hook and moves from the start point of the threading stroke to the end point of the threading stroke. The threader spring nut assembly 100 is mounted in the mounting hole 31.

[0044] The panel 300 has multiple gears in the embodiment, and the thread tension spring nut assembly 100 further comprises the following components:

[0045] An adjusting component 13 is sleeved on the thread tension spring screw 11 and can be operated to rotate and axially move relative to the thread tension spring screw 11, so that the adjusting component 13 can be selectively engaged with one gear of the panel, and the thread tension spring 12 is driven to change the thread tension angle of the thread tension hook 122 by the rotation of the adjusting component 13.

[0046] An elastic component is used to bias the adjusting component 13 towards the panel, and the adjusting component 13 has a tendency to be engaged with the gear under the bias of the elastic component.

[0047] In order to form gears on the panel, the panel 300 has gear grooves 312 distributed in the projection circumference of the thread tension spring nut assembly, and the adjusting component 13 is provided with a gear part 132 for cooperation with the gear groove 312. The adjusting component 13 has an adjusting state and a gear setting state, in the gear setting state, the elastic component drives the gear part 132 to cooperate with the gear groove 312, in the adjusting state, the gear part 132 is disengaged from the gear groove 312 by axially moving the adjusting component forward, and the gear part 132 is cooperated with the gear groove 312 after changing the gear by rotating the adjusting component 13, so as to change the thread tension stroke of the thread tension hook.

[0048] In the above technical solution, the adjusting component can move forward and backward along the axial direction of the thread tension spring screw, when the adjusting component moves forward, the elastic component is compressed, the adjusting component is released, and the elastic component can drive the adjusting component to reset. In addition, the adjusting component can rotate around the thread tension spring screw, the adjusting component is connected with the thread tension spring, and the rotation of the adjusting component can change the thread tension angle (rotation angle during the thread tension process, i.e. thread tension stroke) of the thread tension hook. After the change of the thread tension angle, the thread tension suitable for embroidery is obtained.

[0049] In order to keep the position of the adjusting component after rotation and keep the set thread tension angle, the adjusting component is provided with a gear part, and after the gear part cooperates with the gear groove on the panel, the adjusting component can keep the position.

[0050] Compared with the prior art, in order to realize the adjustment of the thread tension spring, only one adjusting component needs to be set, and the gear groove can be directly machined on the panel, and the elastic component is a conventional component in the existing thread tension spring nut assembly, so that the number of components is less and the cost is lower.

[0051] In addition, in the adjustment, the adjustment component is axially moved to disengage the gear portion from the gear slot, and the adjustment component is rotated to engage the gear portion with the gear slot after the gear is changed. In the gear setting state, the elastic component drives the adjustment component to engage the gear portion with the gear slot, and no additional locking is needed, so the adjustment and gear setting locking are convenient.

[0052] Furthermore, compared with the prior art, the thread tension for embroidery can be obtained by changing the thread lifting stroke of the thread lifting spring, and the change before and after the adjustment is more obvious.

[0053] The adjustment component 13 can be a circular plate structure, and a handle portion can be arranged on the outer circle of the adjustment component to facilitate the axial movement and rotation of the adjustment component.

[0054] It can be understood that the gear slot only needs to be arranged at the corresponding projection circumferential local position of the face plate of the thread lifting spring nut assembly, because this can meet the adjustment requirement of the thread lifting spring.

[0055] It can be understood that the adjustment component and the gear cooperation structure on the face plate can also be replaced by other conventional structures.

[0056] In the embodiment, the thread lifting hook is rotated to change the thread lifting angle, the relative position of the thread lifting hook is changed, and the starting point of the thread lifting stroke is changed. Specifically, the thread lifting hook 122 is provided with a limiting portion 123, the adjustment component 13 is provided with a limiting surface 1311, the limiting surface 1311 cooperates with the limiting portion 123 to position the starting point of the thread lifting stroke of the thread lifting hook, and the limiting surface of the adjustment component 13 is changed after the gear is changed, thereby changing the starting point of the thread lifting stroke of the thread lifting hook.

[0057] Further, the face plate 300 is provided with gear indication grooves 311 corresponding to the circumferential interval distribution of the thread lifting spring nut assembly, and the adjustment component 13 is provided with a gear indication portion 131, which cooperates with the gear indication groove 311 to indicate the gear after adjustment. It can be understood that, in order to facilitate observation, the gear indication groove 311 extends to the radial outside of the projection of the thread lifting spring nut assembly, and the gear indication portion 131 extends to the radial outside of the projection of the thread lifting spring nut assembly. Specifically, the gear indication portion 131 is L-shaped, including a radial extension portion located at the rear side of the adjustment component and an axial extension portion connected to the radial outer end of the radial extension portion and extending forward, wherein the axial extension portion is located at the radial outside of the projection of the thread lifting spring nut assembly on the projection of the face plate. The gear indication portion 131 not only has the function of indicating the gear, but also has the same gear setting function as the gear portion 132.

[0058] Further, the limiting surface 1311 can be arranged on the gear position indicating part 131. Thus, the gear position indicating part can serve multiple purposes, and an additional limiting part is not needed. Of course, an additional limiting part can also be arranged, and the limiting surface can be arranged on the limiting part.

[0059] In the prior art, in order to detect whether the thread take-up spring nut assembly is working normally, a conductive part is usually arranged. If working normally, the thread hook 122 will contact the conductive part during the reciprocating thread taking process. If a fault occurs, the thread hook 122 cannot reciprocate to take thread, and of course, will not contact the conductive part, so that the electric signal is interrupted, and the fault is detected to alarm. Usually, the conductive part is provided with a conductive element, and the conductive element is fixed on a part connected with the thread take-up spring by a screw. This is not only troublesome to fix, but also not beautiful.

At the same time, the gear position indicating part is in conductive connection with the conductive sheet, and the conductive part is connected with the conductive sheet.

[0060] Specifically, the conductive sheet is integrally injection molded with the adjusting part 13, and the gear position indicating part 131 and the conductive sheet are an integral structure. Thus, the number of parts can be reduced, and the cost can be reduced. The conductive part comprises an inductive compression spring 15, and the front end of the inductive compression spring 15 abuts against the conductive sheet, so that the conductive connection can be maintained at all times. In addition, the conductive part further comprises an alarm connecting sheet 33, and the inductive compression spring 15 is connected with the alarm connecting sheet 33. The inductive compression spring 15 is provided with a connecting ring 152 and a connecting segment 151 connecting the connecting ring and the compression spring body, and the alarm connecting sheet 33 is connected with a fastening screw 331 fixing the connecting ring 152 thereon. In addition, the face plate 300 is provided with a through hole 32 on the radial outer side of the mounting hole 31, the connecting segment 151 passes through the through hole 32, and the alarm connecting sheet 33 is located on the rear side of the face plate. In the present embodiment, the conductive alarm structure connects the conductive sheet and the alarm connecting sheet by using the inductive compression spring. Since the front end of the inductive compression spring abuts against the conductive sheet, the conductive connection can be maintained at all times, and the inductive compression spring does not need to be fixed by a fastening screw. In addition, the conductive sheet is integrally injection molded with the adjusting part 13, and the conductive sheet does not need to be additionally assembled. Thus, the structure is simplified. One alarm connecting sheet 33 can be used to connect a row of thread take-up spring nut assemblies 100, and the wiring is simplified.

[0061] Specifically, the thread tension spring screw 11 is a stepped shaft, wherein a middle part is provided with a large diameter section 111, a front part is provided with a threaded section 112 with a smaller diameter than the large diameter section, and a limiting slot 113 extending in axial direction and penetrating in radial direction, and a rear part is provided with a small diameter section 114 with a smaller diameter than the large diameter section, and the small diameter section penetrates through the mounting hole 31 on the face plate. The thread tension spring 12 is sleeved on the large diameter section, the large diameter section is provided with a clamping groove 1111 on an outer circle, the thread tension spring is provided with a clamping leg 121, the clamping leg 121 cooperates with the clamping groove 1111, so that the position of the thread tension spring is fixed, the thread tension spring cannot rotate relative to the thread tension spring screw, and the starting position of the thread tension hook can be changed, so that the thread tension force can be changed.

[0062] In addition, with reference to the prior art, the thread tension spring nut assembly 100 further comprises a thread passing wheel 16 movably sleeved on the thread tension spring screw 11 and located between the adjusting part front side and the thread tension spring nut 14, a thread clamping bowl 17, and a thread clamping spring 18, wherein the bowl opening of the thread clamping bowl 17 faces the thread clamping spring 18, and the thread clamping spring 18 is a tower spring, and a large diameter end of the thread clamping spring 18 is located in the thread clamping bowl. Felt 161 is arranged between the thread passing wheel 16 and the thread clamping bowl 17, and between the thread passing wheel 16 and the adjusting part 13. A recess is formed on an end surface of the thread clamping nut 14 facing the thread clamping spring, a tooth surface is formed on a bottom surface of the recess, a stop ring 19 is arranged in the recess and cooperates with the tooth surface, the stop ring 19 is sleeved on the thread tension spring screw 11, and a limiting strip 191 of the stop ring is inserted into the limiting slot 113 of the thread clamping screw. Here, the thread clamping spring 18 serves as an elastic part, and can drive the adjusting part to move rearward, so that the gear part cooperates with the gear slot.
