In the embroidery process, the driving pulley and the elastic bead feeding clamp are used to achieve continuous bead feeding. In order to better limit the running stability of the driving pulley and the elastic bead feeding clamp, the driving pulley and the elastic bead feeding clamp are usually restricted in the slide groove of the base by using the upper cover plate or other parts that work together. However, the structure of the upper cover plate increases the installation complexity of the pulley and the elastic bead feeding clamp on the one hand, and the movement accuracy of the elastic bead feeding clamp will be affected when the upper cover plate is loosened on the other hand. On the other hand, upper covers of different structures need to be matched with elastic bead feeding clamps of different thicknesses for use.

DETAILED DESCRIPTION

[0039] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the implementation modes and the accompanying drawings. Here, the illustrative implementation modes and descriptions of the present application are used to explain the present application, but are not intended to limit the present application.

[0040] refer to Figures 1 to 15 ,like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, this embodiment provides an embroidery bead feeding mechanism, the base 1 of the embroidery bead feeding mechanism has a slide groove 11 that is slidably matched with the driving pulley 2, and an elastic clip guide structure is provided on the inner wall of the slide groove 11. The elastic clip guide structure cooperates with the elastic bead feeding clip 3 located in the slide groove 11 to guide and limit the sliding of the elastic bead feeding clip 3. A bead guide frame 4 is installed on the base 1, and the bead guide frame 4 is used to guide the embroidery beads into the elastic bead clamping opening 39 of the elastic bead feeding clip 3, wherein the inner wall of the slide groove 11 is composed of two groove side walls that are slidably fitted with the two sides of the driving pulley 2 and a groove bottom wall that is slidably fitted with the bottom surface of the driving pulley 2 and connected between the two groove side walls. The elastic clip guide structure cooperates with the elastic bead feeding clip to realize the motion guidance of the elastic bead feeding clip and the driving pulley, so that the elastic bead feeding clip can be stable during operation, saving the use of the upper cover plate, and simplifying the structure and installation process.

[0041] Specifically, one structure of the elastic clip guide structure is an elastic clip limiting groove 13 or an elastic clip limiting slider arranged on the inner wall of the slide groove 11, and the elastic clip limiting groove 13 or the elastic clip limiting slider slides with the guide connection part 31 of the elastic bead feeding clamp 3 to form a guide rail slider motion pair; another structure of the elastic clip guide structure is a roller arranged on the inner wall of the slide groove 11, and the roller is used to slide along the groove arranged on the side of the elastic bead feeding clamp 3 to limit the sliding of the elastic bead feeding clamp 3, or the roller is used to press on the top surface of the elastic bead feeding clamp 3 to limit the sliding of the elastic bead feeding clamp 3. When installing the driving pulley 2 and the elastic bead feeding clamp 3, they are directly installed by sliding in, and the installation process is simple. When the guide connection part 31 of the elastic bead feeding clamps of different thickness specifications has the same size specifications, the above structure can be used to conveniently replace the elastic bead feeding clamps of different thickness specifications for use to meet the use of beads of different heights.

[0042] In the present application, preferably, the elastic clip guide structure is an elastic clip limiting groove 13 or an elastic clip limiting slider arranged on the inner wall of the slide groove 11, and the elastic bead feeding clamp 3 has a guide connection part 31 that is slidably connected to the elastic clip limiting groove 13 or the elastic clip limiting slider, wherein the structure of the guide connection part 31 is a slide groove or a slide rail that slidably cooperates with the elastic clip guide structure.

[0043] Specifically, taking the elastic clip guide structure as the elastic clip limiting groove 13 as an example for specific description, the elastic clip limiting groove 13 can be located on the groove side wall or the groove bottom wall of the slide groove 11. When the elastic clip limiting groove 13 is located on the groove side wall of the slide groove 11, and when the driving pulley 2 and the elastic bead feeding clamp 3 are overlapped as shown in the figure, the driving pulley 2 is located below the elastic bead feeding clamp 3. One implementation method is: the guide connection part 31 located on the side of the elastic bead feeding clamp 3 slides with the corresponding elastic clip limiting groove 13. Preferably, the elastic clip guide structure is located on the groove side wall of the slide groove 11, and the cross-section of the elastic clip limiting groove 13 / elastic clip limiting slider is rectangular, semicircular or triangular. When the elastic clip limiting groove 13 slides with the guide connection part 31 of the elastic bead feeding clamp 3, the elastic bead feeding clamp 3 and the driving pulley 2 can be simultaneously realized. Limiting, the two convex shafts 24 arranged on the driving pulley 2 respectively cooperate with the two driving grooves 35 located on the two elastic clamping arms 34 of the elastic bead feeding clamp 3, and the cooperative working principle of the driving pulley 2 and the elastic bead feeding clamp 3 belongs to the prior art, such as CN207176261U; when the elastic clamp guide structure is located on the bottom wall of the slide groove 11 (not shown in the figure), the guide connecting part 31 is located on the bottom surface of the elastic bead feeding clamp 3 (not shown in the figure), the structure of the elastic clamp guide structure and the structure of the guide connecting part 31 that are slidably connected together are a guide groove or guide rail with a T-shaped or dovetail-shaped cross-section, and when the bottom wall of the slide groove 11 is provided with a boss 12 located between the two sliding arms 22 of the driving pulley 2, the elastic clamp guide structure is arranged on the top surface of the boss 12, and the two convex shafts 24 are respectively located on the corresponding sliding arms 22.

[0044] In the embodiment of the present application, a pulley guide structure may be provided on the inner wall of the chute 11, and the pulley guide structure cooperates with the driving pulley 2 located in the chute 11 to guide and limit the sliding of the driving pulley 2, wherein the specific structure of the pulley guide structure may refer to the structure of the elastic clip guide structure mentioned above. The structure can be used to prevent the driving pulley 2 from tilting during operation and causing vibration of the elastic bead feeding clamp 3, so that the elastic bead feeding clamp 3 can also work stably under high-speed operation conditions.

[0045] When the driving pulley 2 and the elastic bead feeding clamp 3 are overlapped and arranged, and the pulley guiding structure is located on the groove side wall of the slide groove 11 (not shown in the figure), the limiting connection part located on the side of the driving pulley 2 slides with the corresponding pulley guiding structure, and the pulley guiding structure and the elastic clip guiding structure located on the groove side wall of the slide groove 11 are independently arranged, respectively completing the sliding limit of the driving pulley 2 and the elastic bead feeding clamp 3; when the pulley guiding structure and the elastic clip guiding structure located on the groove side wall of the slide groove 11 are connected and merged into one, the driving pulley 2 and the elastic bead feeding clamp 3 can be guided and limited together; another embodiment is: the pulley guiding structure is located on the groove side wall of the slide groove 11, the elastic clip guiding structure is arranged on the groove bottom wall of the slide groove 11, the limiting connection part located on the side of the driving pulley 2 slides with the corresponding pulley guiding structure, and the elastic clip guiding structure located on the groove bottom wall of the slide groove 11 slides and is connected with the guiding connection part 31 (not shown in the figure) located on the bottom surface of the elastic bead feeding clamp 3. Another embodiment is: the pulley guide structure and the elastic clip guide structure are both located on the bottom wall of the slide groove 11, the limiting connection part located at the bottom of the driving pulley 2 is slidably matched with the corresponding pulley guide structure, and the corresponding elastic clip guide structure is slidably matched with the corresponding guide connection part 31 (not shown in the figure) located on the bottom surface of the elastic bead feeding clamp 3; Another embodiment is: the pulley guide structure is located on the bottom wall of the slide groove 11, the limiting connection part located at the bottom of the driving pulley 2 is slidably matched with the corresponding pulley guide structure, the elastic clip guide structure (not shown in the figure) arranged on the slide arm 22 of the driving pulley 2 cooperates with the guide connection part (not shown in the figure) located on the bottom surface of the bead supporting plate 32 of the elastic bead feeding clamp 3 to guide and limit the sliding of the elastic bead feeding clamp 3, and at the same time, the side of the elastic bead feeding clamp 3 is provided with a guide connection part 31 that cooperates with the elastic clip guide structure located on the groove side wall of the slide groove 11, wherein, when a boss 12 is provided on the bottom wall of the slide groove 11, the pulley guide structure is located on one side of the boss 12.

[0046] When only a pulley guide structure is provided on the inner wall of the slide groove 11: the driving pulley 2 and the pulley guide structure slide in cooperation to guide and limit the sliding of the driving pulley 2, and the elastic clip guide structure (not shown in the figure) arranged on the slide arm 22 of the driving pulley 2 cooperates with the guide connection part (not shown in the figure) located on the bottom surface of the elastic bead feeding clamp 3 to guide and limit the sliding of the elastic bead feeding clamp 3, and the guide connection part is a guide groove or guide rail with a T-shaped or dovetail-shaped cross-section, so as to prevent the elastic bead feeding clamp 3 from lifting up and separating from the driving pulley 2, affecting the working reliability.

[0047] When the driving pulley 2 and the elastic bead feeding clamp 3 are arranged flat, such as CN109881395B, when the driving pulley 2 slides with the pulley guide structure located on the groove side wall of the slide groove 11, the structure of the pulley guide structure is a slide groove or slide rail with a rectangular, semicircular, triangular or trapezoidal cross-section, and when the driving pulley 2 slides with the pulley guide structure located on the groove bottom wall of the slide groove 11, the structure of the pulley guide structure is a guide groove or guide rail with a T-shaped or dovetail-shaped cross-section, and the driving groove 35 is in a bottom sealing shape. The driving arm of the driving pulley 2 is used to block the bottom of the driving groove 35 to form a downward pressure to achieve the limitation of the elastic bead feeding clamp 3, or the slide arm 22 of the driving pulley 2 is provided with a guide groove or guide rail that slides with the guide connection part 31 of the elastic bead feeding clamp 3 on the inner side surface close to the elastic bead feeding clamp 3, or the slide arm 22 is provided with a roller shaft that can prevent the elastic bead feeding clamp 3 from tilting up.

[0048] During the implementation of the present application, an elastic clip guide structure can also be set on the top surface of the base 1. The elastic clip guide structure is a guide groove or guide rail with a T-shaped or dovetail-shaped cross-section. The elastic bead feeding clamp 3 is limited by sliding cooperation of the guide connection part set on the side of the elastic bead feeding clamp 3, and the sliding position of the driving pulley 2 is limited at the same time.

[0049] In the present application, preferably, the driving pulley 2 is overlapped with the elastic bead feeding clamp 3, and the two elastic clamp limiting grooves 13 located on the two opposite groove side walls of the slide groove 11 are respectively slidably matched with the guide connecting parts 31 located on the corresponding sides of the elastic bead feeding clamp 3, which is simple to install and process.

[0050] In the embodiment of the present application, the front end of the base 1 and the front end of the elastic bead feeding clamp 3 are both pointed, and the angle of the pointed corner of the elastic bead feeding clamp 3 is smaller than the angle of the pointed corner of the base 1 .

[0051] Specifically, the front end of the base 1 is pointed, which makes it smaller than the existing rectangular or trapezoidal shape, and the pointed shape is preferably an isosceles triangle. The angle of the pointed corner of the elastic bead feeding clamp 3 is smaller than the angle of the pointed corner of the base 1, so that the elastic bead feeding clamp 3 will not exceed the width range of the base 1 when it is retreated and the bead receiving port is opened, thereby ensuring that it will not affect the normal operation of other embroidery machines used in conjunction with it. Preferably, the pointed corner of the pointed corner is set in an arc shape, and the arc shape setting can shorten the invalid extension length of the base 1 as much as possible, and the movement stroke of the elastic bead feeding clamp 3 can be reduced to improve production efficiency. The front end of the elastic bead feeding clamp 3 is pointed, and the position of the driving groove 35 needs to be moved backward to meet normal use. The backward movement of the driving groove 35 will increase the distance between the driving groove 35 and the elastic bead clamping port 39 of the elastic bead feeding clamp 3, thereby reducing the force exerted by the elastic bead clamping port 39 on the beads and reducing the breakage rate of the beads during the bead feeding process.

[0052] During the implementation of the present application, when it is necessary to arrange multiple bases 1 according to the arrangement positions of multiple embroidery machine heads, the structure of the front end of the base 1 and the front end of the elastic bead feeding clamp 3 can also be adjusted as needed. When two bases 1 are used in combination, the front end of the base 1 and the front end of the elastic bead feeding clamp 3 can be angled. When three bases 1 are used in combination, the front end of the base 1 located on both sides and the front end of the elastic bead feeding clamp 3 can be angled, and the front end of the base 1 located in the middle position and the front end of the elastic bead feeding clamp 3 are pointed.

[0053] In the embodiment of the present application, the rear side of the base 1 has an extension 16 for installing the bead guide frame 4, and the arm of the bead guide frame 4 with the bead hole 41 is located in the space directly above the base 1. By installing the bead guide frame 4 on the side, the width of the front end of the base 1 can be made as narrow as possible, making the present application compact and better meeting the needs of small spaces and multi-type embroidery machines.

[0054] Specifically, the extension portion 16 is as close as possible to the rear end portion of the base 1 (the end away from the elastic bead clamping mouth 39 of the elastic bead feeding clamp 3), and the front end width of the base 1 is reduced by not providing a side connecting portion at the front end of the base 1, thereby facilitating the completion of bead embroidery work in a small space, and the turning arm of the bead guide frame 4 with the bead hole 41 is located in the space directly above the base 1, which can prevent the bead guide frame 4 from exceeding the width range of the base 1 and affecting the normal operation of other embroidery machines used in conjunction with it, thereby minimizing the occupied space of the present application as much as possible.

[0055] In the embodiment of the present application, the bead guide frame 4 may be provided with front and rear limit parts that can limit the maximum movement stroke of the driving pulley 2. The driving pulley 2 may move forward too much, causing excessive bead clamping force, or move backward too much, causing excessive deformation of the elastic clamp arm 34 of the elastic bead feeding clamp 3, which is difficult to reset. The specific structure can refer to the existing embroidery bead feeding mechanism.

[0056] In the embodiments of the present application, preferably, Fig. 9 and Fig.10 As shown, a boss 12 is provided in the slide groove 11, and the boss 12 is located between the two slide arms 22 of the driving pulley 2. The elastic bead feeding clamp 3 works in close contact with the boss 12, and a sliding groove is provided on the top surface of the boss 12. The limit column 37 located on the bottom surface of the elastic bead feeding clamp 3 can move in the sliding groove. When in use, the front and / or rear limit movement positions of the elastic bead feeding clamp 3 can be limited by the cooperation between the limit column 37 and the sliding groove to avoid overshoot of the elastic bead feeding clamp 3. At the same time, the scattered beads or broken beads can be temporarily stored in the sliding groove to avoid the beads or broken beads affecting the continuous movement and working reliability of the elastic bead feeding clamp 3.

[0057] In the embodiment of the present application, the sliding groove includes an upper groove 14 with a sealed bottom and a leak hole 15 connected to the rear end of the upper groove 14, and the width of the leak hole 15 is greater than the width of the upper groove 14. The width of the upper groove 14 is slightly greater than the diameter of the limiting column 37 to form a clearance fit. When the limiting column 37 moves, the broken beads or beads in the upper groove 14 can be pushed into the leak hole 15. The leak hole 15 has a large width and can quickly discharge the beads to avoid a large amount of accumulation of broken beads or beads. In actual use, the upper groove 14 can also be processed into a through hole shape that passes through the bottom as needed.

[0058] In an embodiment of the present application, the length of the sliding groove is equal to or greater than the movement stroke of the elastic bead feeding clamp 3. When the length of the sliding groove is equal to the movement stroke of the elastic bead feeding clamp 3, the front and rear limit positions of the elastic bead feeding clamp 3 can be limited.

[0059] In the embodiment of the present application, preferably, the length of the sliding groove is greater than the movement stroke of the elastic bead feeding clamp 3, and the limit column 37 can be abutted against the inner wall of the groove of the leak hole 15 when retreating. Increasing the length of the sliding groove can increase the capacity, and avoid broken beads staying on the elastic bead feeding clamp 3 and / or the driving pulley 2 as much as possible, thereby reducing the frequency of shutdown for cleaning and improving production efficiency.

[0060] In the embodiments of the present application, Fig.11 and Fig.12 As shown, the driving pulley 2 also includes a slide seat 21 connected to two slide arms 22. The slide seat 21 is connected to the driving fork to drive the driving pulley 2 to move. The driving pulley 2 has a ball pushing inclined surface 23 facing the elastic bead feeding clamp 3 and located behind the elastic bead feeding clamp 3.

[0061] Specifically, the ball pushing slope 23 is located at the connection between the slide seat 21 and the slide arm 22. When the driving pulley 2 moves, the broken beads are pushed into the sliding groove by using the ball pushing slope 23. At the same time, the ball pushing slope 23 is also equivalent to setting a reinforcing rib, which improves the strength of the connection between the slide seat 21 and the slide arm 22, and enhances the structural strength and service life of the driving pulley 2. Among them, a lower groove 25 that can reduce the contact area is provided on the bottom surface of the slide arm 22, thereby reducing the contact friction, making the movement process of the driving pulley 2 labor-saving and smooth. The setting of the ball pushing slope 23 can also facilitate the installation of the driving pulley 2.

[0062] In the embodiments of the present application, Fig.13 , Fig.14 and Fig.15 As shown, the rear end of the elastic bead feeding clamp 3 away from the elastic bead clamping opening 39 has a bead scraping cut surface 38.

[0063] Specifically, the bead scraping surface 38 faces the bottom, which can prevent the beads from bouncing and scattering while scraping the beads.

[0064] In an embodiment of the present application, the elastic bead feeding clamp 3 comprises a bead supporting plate 32, side arms 33 respectively located on both sides of the bead supporting plate 32, and two elastic clamping arms 34, an elastic bead clamping opening 39 is formed between the two elastic clamping arms 34, the elastic clamping arm 34 is connected to the end of the corresponding side arm 33 through a U-shaped arm, the U-shaped arm is located between the corresponding side arm 33 and the bead supporting plate 32, and the front end of the side arm 33 has a guide slope 331.

[0065] The bead feeding clamp 330 is convenient to install in the limit groove 13 by utilizing the guiding slopes 331 on both sides, and the guiding slopes 331 also have the function of limiting the maximum opening range of the elastic bead feeding opening 39. When the elastic clamp arm 34 is driven by the convex shaft 24 to open the elastic bead feeding opening 39, the U-shaped arm will be deformed, and the deformation of the U-shaped arm and the squeezing of the elastic clamp arm 34 will drive the front end of the side arm 33 to deflect, thereby increasing the space for the swing of the elastic clamp arm 34, so that the elastic bead feeding opening 39 is enlarged to meet the needs of delivering beads of larger size. When the guiding slopes 331 are abutted against the side walls of the slide groove 11, the side arm 33 cannot continue to deform, thereby preventing the elastic clamp arm 34 from continuing to deform, limiting the maximum opening size of the elastic bead feeding opening 39, and avoiding excessive deformation of the elastic clamp arm 34 that affects the clamping reliability of the elastic bead feeding opening 39.

[0066] In an embodiment of the present application, at least one magnetic piece 36 is provided on the bottom surface of the bead supporting plate 32, and the width of the magnetic piece 36 is greater than the width of the leakage hole 15, so that the magnetic piece 36 is easy to install and not easy to fall off, wherein the magnetic piece 36 can be selected as a magnet or an electromagnetic coil connected to a power supply.

[0067] Based on the above technical solution disclosed in this application, this application discloses another technical solution:

[0069] The above description is only the preferred embodiment of the present application and is not intended to limit the present application.
