It is also necessary to explain that, for ease of description, only the parts related to the invention are shown in the accompanying drawings.

[0042] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0043] Please see Figure 1 The present application provides a thread passing mechanism, including a thread passing plate 10, wherein the thread passing plate 10 is provided with at least one thread passing hole 20 and a blocking column 30 matched with the at least one thread passing hole 20, wherein the circumferential surface of the blocking column 30 includes an embroidery thread contact area 31 and an embroidery thread non-contact area 32, wherein the cross-sectional shape of the embroidery thread contact area 31 in a direction perpendicular to the axis of the blocking column 30 is an arc, and a ceramic contact layer 33 is provided on the embroidery thread contact area 31.

[0044] Figure 2 FIG. 2 shows a schematic diagram of the embroidery thread passing through the thread passing mechanism. The embroidery thread 1 passes through the thread passing hole 20, is tangent to the circumferential surface of the blocking column 30 from one side a of the blocking column 30, and passes around a part of the circumferential surface of the blocking column 30 (i.e., the embroidery thread contact area 31), and then passes through the thread passing hole 20 from the other side b of the blocking column 30. Figure 2 The embroidery thread 1 is shown in the state of being not tensioned. The embroidery thread contact area 31 is the area where the embroidery thread is bypassed on the blocking column 30, and the other areas of the circumferential surface of the blocking column 30 except the embroidery thread contact area 31 are all embroidery thread non-contact areas 32.

[0045] It should be noted that the shape of the embroidery thread contact area 31 is not limited in the embodiment of the present application. The cross-sectional shape of the embroidery thread contact area 31 can be a circular arc or an elliptical arc, and the embroidery thread can contact the embroidery thread contact area 31 on the embroidery thread contact area 31. It is set as needed in different embodiments.

[0046] In one embodiment of the present application, Figure 3-4 As shown, the wire plate 10 can be fixedly arranged on the wire panel 50. The wire plate 10 is provided with at least one mounting hole 11 and a support 40 fixedly arranged on the mounting hole 11, the wire hole 20 is arranged on the support 40, and the support 40 is made of ceramic material.

[0047] In the embodiment of the present application, a support 40 made of ceramic material is provided on the thread passing hole 20, so that the friction between the embroidery thread and the support 40 can be reduced when the embroidery thread passes through the thread, making the thread passing smoother, reducing problems such as thread breakage and wool, and improving the embroidery quality and the service life of the embroidery machine.

[0048] It is understandable that the number of the wire holes 20 and the supports 40 is not limited in the embodiment of the present application and can be adjusted as needed.

[0049] In one embodiment of the present application, the blocking column 30 is rod-shaped, and a plurality of the wire holes 20 share the same blocking column 30 ; a support frame 12 is provided on the wire plate 10 , and the blocking column 30 is fixedly provided on the support frame 12 .

[0050] In the embodiment of the present application, the fixing method is simple by using a method in which multiple thread holes 20 share the same blocking column 30. The axis direction of the blocking column 30 is arranged along the arrangement direction of the thread holes 20, and the axis direction of the blocking column 30 is perpendicular to the thread passing direction of the embroidery thread. The blocking column 30 can be fixedly arranged above the thread hole 20 or below the thread hole 20.

[0051] In one embodiment of the present application, Figure 5 As shown, the number of the blocking posts 30 corresponds to the number of the wire-passing holes 20 , and the blocking posts 30 are fixedly disposed in the wire-passing holes 20 of the support 40 .

[0052] In the embodiment of the present application, the axis direction of the blocking column 30 is perpendicular to the thread passing direction of the embroidery thread. By arranging the blocking column 30 in the thread passing hole 20, the space of the embroidery machine can be saved, and other thread passing mechanisms can be prevented from being affected, thereby improving the space utilization rate. By arranging the blocking column 30 on the support 40, the component structure is simplified and the assembly is convenient.

[0053] It should be noted that the structure and shape of the blocking column 30 are not limited in the embodiment of the present application, and a variety of configurations of the blocking column 30 are shown in the present application.

[0054] In an optional embodiment of the present application, the cross-sectional shape of the blocking column 30 may be circular, and the material of the blocking column 30 may be ceramic. Then, the ceramic contact layer 33 covers both the embroidery thread contact area 31 and the embroidery thread non-contact area 32 .

[0055] In an optional embodiment of the present application, Figure 6 As shown, the cross-sectional shape of the blocking column 30 can be circular, and the cross-sectional shape of the ceramic contact layer 33 can be annular. The ceramic contact layer 33 is sleeved on the outer peripheral surface of the blocking column 30, and the ceramic contact layer 33 covers both the embroidery thread contact area 31 and the embroidery thread non-contact area 32.

[0056] In an optional embodiment of the present application, Figure 7 As shown, the blocking column 30 includes a first column 21 and a second column 22 which are fixedly connected, the first column 21 is made of ceramic material, the second column 22 is made of non-ceramic material or ceramic material, the embroidery thread contact area 31 is arranged on the circumferential surface of the first column 21, the embroidery thread non-contact area 32 is arranged on the circumferential surface of the second column 22, and the diameter of the second column 22 is smaller than the diameter of the second column 22.

[0057] In the embodiment of the present application, a two-stage barrier column 30 structure is adopted. By setting the embroidery thread contact area 31 on the first column 21 and making the diameter of the second column 22 of the non-embroidery thread contact area 31 smaller than the diameter of the first column 21, the embroidery thread can be prevented from contacting the barrier column 30, thereby reducing friction, preventing problems such as embroidery thread breakage and wool yarn, and improving the embroidery quality.

[0058] The first column 21 is provided with a groove 23 , and the second column 22 is provided with a protrusion 24 that is snap-fitted with the groove 23 ; or the first column 21 is provided with a groove 23 , and the second column 22 is provided with a groove 23 that is snap-fitted with the protrusion 24 .

[0059] In the present application, the first column 21 and the second column 22 can be fixedly connected by bonding or other methods, and the groove 23 and the protrusion 24 are provided for clamping, thereby improving the positioning accuracy and connection strength of the first column 21 and the second column 22. In the embodiment of the present application, the arrangement of the groove 23 and the protrusion 24 is not limited, and can be adjusted as needed in different embodiments.

[0060] In an optional embodiment of the present application, Figure 8As shown, the embroidery thread non-contact area 32 of the blocking column 30 is parallel to the plane where the diameter of the blocking column 30 is located. That is, only the first column 21 is included, and the shape of the first column 21 is semicircular, and the first column 21 is made of ceramic material. By only providing the first column 21, the friction between the embroidery thread and the embroidery thread can be reduced, and the problems of thread breakage and wool can be reduced, thereby improving the embroidery quality.

[0061] It should be noted that the height of the blocking column 30 is not limited in this embodiment, and the height of the blocking column 30 can be equal to the radius of the circle where the embroidery thread contact area 31 is located. Of course, the height of the blocking column 30 can also be less than the radius of the circle where the embroidery thread contact area 31 is located, so as to reduce the length of the embroidery thread contact area 31 and reduce the friction of the embroidery thread.

[0062] In an optional embodiment of the present application, the embroidery thread non-contact area 32 may also be a curved surface shape. For example, the shape of the first cylinder 21 may be an ellipse (eg Fig. 9 as shown) or crescent-shaped (as Fig.10 As shown), etc., can be set as needed in different embodiments.

[0063] Optionally, the wire hole 20 is an elongated hole. In the embodiment of the present application, the shape of the support 40 is not limited, and the shape of the support 40 can match the shape of the wire hole 20, and the shapes of the support 40 and the mounting hole 11 can both be set to be elongated.

[0064] It should be noted that the length direction of the thread hole 20 described in the embodiment of the present application can be along the axial direction perpendicular to the blocking column 30, and the embroidery thread can extend from one side of the length direction of the thread hole 20 through the blocking column 30 to the other side of the length direction of the thread hole 20, which is convenient for threading and can make the threading operation space larger and convenient for operation.

[0065] In one embodiment of the present application, Figure 11-12 As shown, the support 40 includes a main body 41 and a first limiting portion 42 disposed on one side of the main body 41. The support 40 is embedded in the mounting hole 11. The length of the main body 41 is less than the length of the mounting hole 11, and the length of the first limiting portion 42 is greater than the length of the mounting hole 11. The wire-passing plate 10 includes a first surface 101 and a second surface 102 disposed opposite to each other. In one embodiment, the first limiting portion 42 is located above the first surface 101. When the support 40 is embedded in the mounting hole 11, the support 40 can be limited by the first limiting portion 42, thereby simplifying the installation method.

[0066] In another embodiment, the first limiting portion 42 is located below the second surface 102. When the support 40 is embedded in the mounting hole 11, the embroidery thread generates an upward force on the support 40 when passing through the blocking column 30. The support 40 can be limited by the first limiting portion 42 located below the second surface 102. It is set as needed in different embodiments.

[0067] In one embodiment of the present application, Figure 13-14 As shown, the support 40 includes a first limiting portion 42 and a second limiting portion 43 that are relatively arranged, and a slot 44 is formed between the first limiting portion 42 and the second limiting portion 43; the mounting hole 11 is provided with a socket 13 that cooperates with the slot 44, and the slot 44 is inserted into the mounting hole 11 through the socket 13.
